INVESTMENT OBJECTIVE
Janus Henderson International Sustainable Equity ETF seeks long-term growth of capital.
 
FEES AND EXPENSES OF THE FUND
This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. Investors may pay brokerage commissions and other fees to financial intermediaries on their purchases and sales of Fund shares, which are not reflected in the table or in the example below.
 
ANNUAL FUND OPERATING EXPENSES
(expenses that you pay each year as a percentage of the value of your investment)
 
Management Fees
     0.60%  
Other Expenses
     0.00%  
Total Annual Fund Operating Expenses
     0.60%  
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
      1 Year      3 Years      5 Years      10 Years  
   $   61      $   192      $   335      $   750  
Portfolio Turnover:  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.
 
PRINCIPAL INVESTMENT STRATEGY
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities. The Fund seeks to invest in companies whose products and services are considered by the Adviser as contributing to positive environmental or social change and sustainable economic development, including those that are strategically aligned with environmental and social megatrends such as climate change, resource constraints, growing populations, and aging populations.
The Fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. A security is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the company’s revenues are derived from one or more countries; or (iii) a majority of the company’s assets are located in one or more countries. The Fund’s investments may be in non-U.S. currency or U.S. dollar-denominated. 
The Fund generally invests in a core group of 30-50 equity securities, which consist primarily of common stocks, but may also include other types of instruments, such as warrants. The Fund may also invest in equity securities of real estate-related companies, including real estate investment trusts (“REITs”) and similar REIT-like entities. The Fund will invest primarily in larger, well-established companies but may also invest in mid- and small-sized companies. The Fund’s uninvested assets may be held in cash, cash equivalents, and/or affiliated or unaffiliated exchange-traded funds (“ETFs”). 
 
2½Janus Henderson International Sustainable Equity ETF

The Fund is “actively managed” and does not seek to replicate the composition or performance of an index. In selecting investments, the portfolio managers employ a “bottom-up” approach that focuses on fundamental research. To identify the universe of investible securities for the Fund, the portfolio managers first employ positive selection criteria to identify companies that fall within at least one of ten environmental and social themes. Environmental themes include efficiency, cleaner energy, water management, environmental services, and sustainable transport. Social themes include sustainable property and finance, safety, quality of life, knowledge and technology, and health. 
Next, the portfolio managers apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from industries, activities, or assets considered by the portfolio managers to have a negative impact on society or the environment. A current list of such activities, which may evolve over time, follows: 
 
 
alcohol; 
 
animal testing (non-medical); 
 
armaments; 
 
chemicals of concern; 
 
fossil fuel extraction and refining; 
 
fossil fuel power generation; 
 
fur; 
 
gambling; 
 
genetic engineering; 
 
intensive farming; 
 
meat and dairy production; 
 
nuclear power; 
 
pornography; 
 
tobacco; and 
 
United Nations Global Compact and Organization for Economic Co-operation and Development violators. 
In selecting investments, the portfolio managers will then consider, among other factors, a company’s growth potential, competitive positioning, operational quality, and strategy. The portfolio managers may also consider factors such as a company’s historic and projected return on capital, balance sheets, and financial models. The portfolio managers will also consider environmental, social, and governance (“ESG”) factors including, but not limited to, climate change, deforestation, biodiversity, human rights, company culture, and community relations, board structure and diversity, executive pay, and corporate reporting. 
The portfolio managers seek to maintain a portfolio of securities that has a carbon footprint and carbon intensity that is at least 20% below the MSCI All Country World ex-USA IndexSM. At the portfolio managers’ discretion, the Fund will engage with a company’s management regarding matters that may evolve over time and may include shareholder rights, governance and remuneration, climate change, carbon emissions, pollution, biodiversity, human capital, and diversity and inclusion. 
The portfolio managers evaluate and apply ESG and sustainable investment criteria relying on a mix of third-party data and internally-generated analyses based on information that may include web-based research reports from a company or independent sources, as well as corporate engagement. The portfolio managers do not apply ESG and sustainable investment criteria in managing the Fund’s exposure to cash and cash equivalents. The Fund will generally consider selling a stock if, in the portfolio managers’ opinion, there has been a regulatory, industry, or position-level change that may impair a company’s revenue growth. The Fund will also consider selling a stock if, in the portfolio managers’ opinion, the company’s business model no longer meets the sustainable investment criteria employed in managing the Fund. 
 
PRINCIPAL INVESTMENT RISKS
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund invests primarily in common stocks, which tend to be more volatile than many other investment choices. The principal risks associated with investing in the Fund are set forth below.
Market Risk.  The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value (“NAV”) may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions 
 
3½Janus Henderson International Sustainable Equity ETF

and events (such as terrorism, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics, including COVID-19) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. 
Sustainable Investment Risk.  The Fund follows a sustainable investment approach by investing in companies that relate to certain sustainable development themes and demonstrate adherence to ESG practices. Accordingly, the Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector, which may make the Fund more vulnerable to unfavorable developments in a particular sector than funds that invest more broadly. Additionally, due to its exclusionary criteria, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for the Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. 
Industry and Sector Risk.  Although the Fund does not concentrate its investments in specific industries or industry sectors, it emphasizes certain themes and megatrends. As a result, at times, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector or that benefit from the same megatrend. Companies in the same industry or economic sector or that benefit from the same theme may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.  
Issuer Concentration Risk.  The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments. 
Geographic Concentration Risk.  To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance. 
Currency Risk.  Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency. 
Foreign Exposure Risk.  Foreign securities, including emerging markets, can be more volatile than the U.S. markets. As a result, the Fund’s returns and NAV may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries, if any, may involve risks greater than, or in addition to, the risks of investing in more developed countries. 
 
4½Janus Henderson International Sustainable Equity ETF

Emerging Markets Risk.  The risks of foreign investing are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. Additionally, foreign and emerging market risks, including but not limited to price controls, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, nationalization, and restrictions on repatriation of assets may be heightened to the extent the Fund invests in Chinese local market securities. 
Portfolio Management Risk.  The Fund is an actively managed investment portfolio and is therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable investment approach that the Fund employs. The Fund may underperform its benchmark index or other funds with similar investment objectives. 
Small- and Mid-Sized Companies Risk.  Investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. 
Liquidity Risk.  The Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, the Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. 
REIT Risk.  REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. 
Exchange-Traded Funds Risk.  The Fund may invest in ETFs for temporary liquidity purposes, to manage duration and cash positioning, and/or for other purposes. ETFs are typically open-end investment companies which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the NAV of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its NAV. As a result, the Fund may pay more or less than NAV when it buys ETF shares, and may receive more or less than NAV when it sells those shares. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will also bear a pro rata portion of the ETF’s expenses. Additionally, when purchasing or selling shares of an ETF, the Fund may pay commissions or other trading costs as part of the transaction. The Fund is also subject to the risks associated with the securities in which the ETF invests. 
 
5½Janus Henderson International Sustainable Equity ETF

Smaller Sized Fund Risk.  Because the Fund has a small asset base, large inflows and outflows may have a disproportionate impact, negative or positive, on the Fund’s performance, which may be more volatile than that of a larger fund. If a smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors. 
Exchange Listing and Trading Issues Risk.  Although Fund shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund’s shares trading at a premium or discount to its NAV. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund’s listing will continue to be met or will remain unchanged. 
Fluctuation of NAV and Market Price Risk.  The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund’s shares that differ significantly from the Fund’s NAV. Additionally, during a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly, resulting in Fund shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods, which may result in an increase in the variance between market prices of the Fund’s shares and the Fund’s NAV. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices. 
It cannot be predicted whether Fund shares will trade below, at or above the Fund’s NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV when the Exchange re-opens. The Fund’s bid-ask spread and the resulting premium or discount to the Fund’s NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities. 
Authorized Participant Risk.  The Fund may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund’s shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to NAV and possibly face delisting. 
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

MANAGEMENT
Investment Adviser:  Janus Henderson Investors US LLC
Portfolio Managers:  Hamish Chamberlayne, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception. Aaron Scully, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception.
 
PURCHASE AND SALE OF FUND SHARES
The Fund is an actively-managed ETF. Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called “Creation Units” through APs. The Adviser may modify the Creation Unit size with prior notification to the Fund’s APs. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund’s NAV. As a result, you may pay more than NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.
 
7½Janus Henderson International Sustainable Equity ETF

Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Historical information regarding the Fund’s bid/ask spread can be accessed on the Fund’s website at janushenderson.com/performance by selecting the Fund.
 
TAX INFORMATION
The Fund’s distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.
 
PAYMENTS TO BROKER‑DEALERS AND OTHER FINANCIAL INTERMEDIARIES
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

FEES AND EXPENSES OF THE FUND
This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. Investors may pay brokerage commissions and other fees to financial intermediaries on their purchases and sales of Fund shares, which are not reflected in the table or in the example below.
 
ANNUAL FUND OPERATING EXPENSES
(expenses that you pay each year as a percentage of the value of your investment)
 
Management Fees
     0.60%

(1)
Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in other investment companies. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the “Financial Highlights” table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
      1 Year      3 Years      5 Years      10 Years  
   $   62      $   195    $   340      $   762  
Portfolio Turnover:  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 74% of the average value of its portfolio.
 
PRINCIPAL INVESTMENT STRATEGY
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies whose products, services and activities are considered by the Adviser as contributing to or benefiting from the goal of achieving “net zero” carbon emissions through the decarbonization of the global economy, such as carbon reduction, energy transition, sustainable mobility, sustainable industry, and sustainable agriculture. The Fund generally will invest in global companies, primarily in the materials, energy, utility, agricultural, industrial and consumer staple sectors. The Fund seeks to invest in companies that are involved in the production and utilization of resources, equipment and/or commodity-related products that the Adviser believes are necessary to enable a transition to a low-carbon global economy and that the Adviser believes are well-positioned to benefit from ongoing and future demand for natural resources. 
The Fund generally invests in a core group of 35-60 equity securities of companies of any size, from larger, well-established companies to smaller, emerging growth companies. The Fund is classified as non-diversified, which allows it to hold larger positions in securities, compared to a fund that is classified as diversified. The securities in which the Fund invest may include common stocks, preferred stocks, and depository receipts. The Fund may invest in foreign securities, which may include investments in emerging markets. The Fund’s uninvested assets may be held in cash, cash equivalents, and/or affiliated or unaffiliated exchange-traded funds (“ETFs”). 
 
9½Janus Henderson Net Zero Transition Resources ETF

The Fund is “actively managed” and does not seek to replicate the composition or performance of an index. In deciding to add or reduce portfolio positions, the portfolio managers employ a “bottom-up” approach that focuses on fundamental research and considers, among other factors, a company’s growth potential, competitive positioning and operational quality, return on capital, risk profile, and strategy. Except as noted below, in selecting each investment, the portfolio managers will also consider environmental, social, and governance (“ESG”) factors such as carbon footprint, corporate governance, human capital and diversity, and business ethics. The portfolio managers evaluate and apply ESG factors relying on a mix of third-party data and internally-generated analyses based on information that may include web-based research reports from a company or independent sources, as well as corporate engagement, and may sell a portfolio position if, in the portfolio managers’ opinion, the company’s business model no longer satisfies the ESG factors. The portfolio managers do not apply the ESG factors in managing the Fund’s cash and cash equivalents. 
To identify the universe of investible securities for the Fund, the portfolio managers first apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from industries, activities, or assets considered by the portfolio managers to have a negative impact on society or the environment. A current list of such activities, which may evolve over time, follows: 
 
 
alcohol; 
 
animal testing (cosmetic); 
 
armaments; 
 
chemicals of concern; 
 
controversial fossil fuel power generation; 
 
controversial fossil fuel extraction and refining; 
 
fur; 
 
gambling; 
 
pornography; 
 
tobacco; and 
 
United Nations Global Compact violators. 
 
PRINCIPAL INVESTMENT RISKS
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund invests primarily in common stocks, which tend to be more volatile than many other investment choices. The principal risks and special considerations associated with investing in the Fund are set forth below. 
Market Risk.  The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value (“NAV”) may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as terrorism, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics, including COVID-19) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. 
Natural Resources Investment Risk.  Investment in companies in natural resources industries (including those in the energy sector) can be significantly affected by (often rapid) changes in supply of, or demand for, various natural resources. They may also be affected by changes in energy prices, international political and economic developments, environmental incidents, energy conservation, the success of exploration projects, changes in commodity prices, and tax and other government regulations. For example, the COVID-19 pandemic has drastically reduced the demand for various natural resources and has drastically increased the price volatility of natural resources and companies within the natural resources industry. An extended period of reduced (or negative) prices may significantly lengthen the time that companies within the natural resources industries would need to recover after a stabilization of prices. 
Industry and Sector Risk.  Although the Fund does not concentrate its investments in specific industries or sectors, it may a significant portion of its assets invested in securities of companies conducting similar business, or business within the same economic sector. Companies in the same industry or economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility. In 
 
10½Janus Henderson Net Zero Transition Resources ETF

addition, the Fund may be overweight or underweight in certain industries or sectors relative to its benchmark index, which may cause the Fund’s performance to be more or less sensitive to developments affecting those sectors. 
 
 
Industrials Sector Risk.  The industrials sector includes companies in the capital goods, commercial and professional services and transportation industry groups, including companies engaged in the business of human capital management, business research and consulting, air freight and logistics, airlines, maritime shipping and transportation, railroads and trucking, transportation infrastructure, and aerospace and defense. Companies in the industrials sector can be significantly affected by general economic trends, including such factors as employment and economic growth, interest rate changes, changes in consumer spending, legislative and government regulation and spending, import controls, commodity prices, and worldwide competition. Changes in the economy, fuel prices, labor agreements, and insurance costs may result in occasional sharp price movements in transportation securities. 
Sustainable Investment Risk.  The Fund follows a sustainable investment approach by investing in companies that relate to certain sustainable development themes and demonstrate adherence to ESG practices. Accordingly, the Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector, which may make the Fund more vulnerable to unfavorable developments in a particular sector than funds that invest more broadly. Additionally, due to its exclusionary criteria, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for the Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. 
Portfolio Management Risk.  The Fund is an actively managed investment portfolio and is therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable investment approach that the Fund employs. The Fund may underperform its benchmark index or other funds with similar investment objectives. 
Issuer Concentration Risk.  The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments. 
Small- and Mid-Sized Companies Risk.  Investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. 
Currency Risk.  Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency. 
Foreign Exposure Risk.  Foreign securities, including emerging markets, can be more volatile than the U.S. markets. As a result, the Fund’s returns and NAV may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a 
 
11½Janus Henderson Net Zero Transition Resources ETF

significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries, if any, may involve risks greater than, or in addition to, the risks of investing in more developed countries. 
Nondiversification Risk.  The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended. This gives the Fund’s portfolio managers more flexibility to hold larger positions in securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s NAV and total return. 
Smaller Sized Fund Risk.  Because the Fund has a small asset base, large inflows and outflows may have a disproportionate impact, negative or positive, on the Fund’s performance, which may be more volatile than that of a larger fund. If a smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors. 
Exchange-Traded Funds Risk.  The Fund may invest in ETFs for temporary liquidity purposes, to manage duration and cash positioning, and/or for other purposes. ETFs are typically open-end investment companies which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the NAV of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its NAV. As a result, the Fund may pay more or less than NAV when it buys ETF shares, and may receive more or less than NAV when it sells those shares. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will also bear a pro rata portion of the ETF’s expenses. The Fund is also subject to the risks associated with the securities in which the ETF invests. 
Exchange Listing and Trading Issues Risk.  Although Fund shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund’s shares trading at a premium or discount to its NAV. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund’s listing will continue to be met or will remain unchanged. 
Fluctuation of NAV and Market Price Risk.  The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund’s shares that differ significantly from the Fund’s NAV. Additionally, during a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly resulting in Fund shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods, which may result in an increase in the variance between market prices of the Fund’s shares and the Fund’s NAV. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices. 
It cannot be predicted whether Fund shares will trade below, at or above the Fund’s NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV when the Exchange re-opens. The Fund’s bid-ask spread and the resulting premium or discount to the Fund’s NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities. 
Authorized Participant Risk.  The Fund may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund’s shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In 
 
12½Janus Henderson Net Zero Transition Resources ETF

that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to NAV and possibly face delisting. 
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

MANAGEMENT
Investment Adviser:  Janus Henderson Investors US LLC
Portfolio Managers:  Tim Gerrard is Co-Portfolio Manager of the Fund, which he has co-managed since inception. Darko Kuzmanovic is Co-Portfolio Manager of the Fund, which he has co-managed since inception. Tal Lomnitzer, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception. Daniel Sullivan is Co-Portfolio Manager of the Fund, which he has co-managed since inception.
 
PURCHASE AND SALE OF FUND SHARES
The Fund is an actively-managed ETF. Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called “Creation Units” through APs. The Adviser may modify the Creation Unit size with prior notification to the Fund’s APs. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund’s NAV. As a result, you may pay more than NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.
Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Historical information regarding the Fund’s bid/ask spread can be accessed on the Fund’s website at janushenderson.com/performance by selecting the Fund.
 
TAX INFORMATION
The Fund’s distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.
 
PAYMENTS TO BROKER‑DEALERS AND OTHER FINANCIAL INTERMEDIARIES
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

FEES AND EXPENSES OF THE FUND
This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. Investors may pay brokerage commissions and other fees to financial intermediaries on their purchases and sales of Fund shares, which are not reflected in the table or in the example below.
 
ANNUAL FUND OPERATING EXPENSES

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
      1 Year      3 Years      5 Years      10 Years  
   $   56    $   176    $   307      $   689  
Portfolio Turnover:  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 9% of the average value of its portfolio.
 
PRINCIPAL INVESTMENT STRATEGY
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities that are economically tied to the United States. The Fund seeks to invest in companies whose products and services are considered by the Adviser as contributing to positive environmental or social change and sustainable economic development, including those that are strategically aligned with environmental and social megatrends such as climate change, resource constraints, growing populations, and aging populations. A security is deemed to be economically tied to the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in the United States, (ii) a majority of the company’s revenues are derived from the United States or (iii) a majority of the company’s assets are located in the United States.
The Fund generally invests in a core group of 30-50 equity securities, which consist primarily of common stocks, but may also include other types of instruments, such as warrants. The Fund may also invest in equity securities of real estate-related companies, including real estate investment trusts (“REITs”) and similar REIT-like entities. The Fund will invest primarily in larger, well-established companies but may also invest in mid- and small-sized companies. The Fund’s uninvested assets may be held in cash, cash equivalents, and/or affiliated or unaffiliated exchange-traded funds (“ETFs”).
The Fund is “actively managed” and does not seek to replicate the composition or performance of an index. In selecting investments, the portfolio managers employ a “bottom-up” approach that focuses on fundamental research. To identify the universe of investible securities for the Fund, the portfolio managers first employ positive selection criteria to identify companies that fall within at least one of ten environmental and social themes. Environmental themes include efficiency, cleaner energy, 
 
15½Janus Henderson U.S. Sustainable Equity ETF

water management, environmental services, and sustainable transport. Social themes include sustainable property and finance, safety, quality of life, knowledge and technology, and health. 
Next, the portfolio managers apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from industries, activities, or assets considered by the portfolio managers to have a negative impact on society or the environment. A current list of such activities, which may evolve over time, follows: 
 
 
alcohol; 
 
animal testing (non-medical); 
 
armaments; 
 
chemicals of concern; 
 
fossil fuel extraction and refining; 
 
fossil fuel power generation; 
 
fur; 
 
gambling; 
 
genetic engineering; 
 
intensive farming; 
 
meat and dairy production; 
 
nuclear power; 
 
pornography; 
 
tobacco; and 
 
United Nations Global Compact and Organization for Economic Co-operation and Development violators. 
In selecting investments, the portfolio managers will then consider, among other factors, a company’s growth potential, competitive positioning, operational quality, and strategy. The portfolio managers may also consider factors such as a company’s historic and projected return on capital, balance sheets, and financial models. The portfolio managers will also consider environmental, social, and governance (“ESG”) factors including, but not limited to, climate change, deforestation, biodiversity, human rights, company culture, and community relations, board structure and diversity, executive pay, and corporate reporting. 
The portfolio managers seek to maintain a portfolio of securities that has a carbon footprint and carbon intensity that is at least 20% below the S&P 500® Index. At the portfolio managers’ discretion, the Fund will engage with a company’s management regarding matters that may evolve over time and may include shareholder rights, governance and remuneration, climate change, carbon emissions, pollution, biodiversity, human capital, and diversity and inclusion. 
The portfolio managers evaluate and apply ESG and sustainable investment criteria relying on a mix of third-party data and internally-generated analyses based on information that may include web-based research reports from a company or independent sources, as well as corporate engagement. The portfolio managers do not apply ESG and sustainable investment criteria in managing the Fund’s exposure to cash and cash equivalents. The Fund will generally consider selling a stock if, in the portfolio managers’ opinion, there has been a regulatory, industry, or position-level change that may impair a company’s revenue growth. The Fund will also consider selling a stock if, in the portfolio managers’ opinion, the company’s business model no longer meets the sustainable investment criteria employed in managing the Fund. 
 
PRINCIPAL INVESTMENT RISKS
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund invests primarily in common stocks, which tend to be more volatile than many other investment choices. The principal risks associated with investing in the Fund are set forth below.
Market Risk.  The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value (“NAV”) may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as terrorism, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics, including COVID-19) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. 
 
16½Janus Henderson U.S. Sustainable Equity ETF

Sustainable Investment Risk.  The Fund follows a sustainable investment approach by investing in companies that relate to certain sustainable development themes and demonstrate adherence to ESG practices. Accordingly, the Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector, which may make the Fund more vulnerable to unfavorable developments in a particular sector than funds that invest more broadly. Additionally, due to its exclusionary criteria, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for the Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. 
Industry and Sector Risk.  Although the Fund does not concentrate its investments in specific industries or industry sectors, it emphasizes certain themes and megatrends. As a result, at times, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector or that benefit from the same megatrend. Companies in the same industry or economic sector or that benefit from the same megatrend may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility. 
Issuer Concentration Risk.  The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments. 
Portfolio Management Risk.  The Fund is an actively managed investment portfolio and is therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable investment approach that the Fund employs. The Fund may underperform its benchmark index or other funds with similar investment objectives. 
Small- and Mid-Sized Companies Risk.  Investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. 
Liquidity Risk.  The Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, the Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. 
REIT Risk.  REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue 
 
17½Janus Henderson U.S. Sustainable Equity ETF

Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. 
Exchange-Traded Funds Risk.  The Fund may invest in ETFs for temporary liquidity purposes, to manage duration and cash positioning and/or for other purposes. ETFs are typically open-end investment companies which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the NAV of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its NAV. As a result, the Fund may pay more or less than NAV when it buys ETF shares, and may receive more or less than NAV when it sells those shares. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will also bear a pro rata portion of the ETF’s expenses. Additionally, when purchasing or selling shares of an ETF, the Fund may pay commissions or other trading costs as part of the transaction. The Fund is also subject to the risks associated with the securities in which the ETF invests. 
Smaller Sized Fund Risk.  Because the Fund has a small asset base, large inflows and outflows may have a disproportionate impact, negative or positive, on the Fund’s performance, which may be more volatile than that of a larger fund. If a smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors. 
Exchange Listing and Trading Issues Risk.  Although Fund shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund’s shares trading at a premium or discount to its NAV. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund’s listing will continue to be met or will remain unchanged. 
Fluctuation of NAV and Market Price Risk.  The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund’s shares that differ significantly from the Fund’s NAV. Additionally, during a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly, resulting in Fund shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods, which may result in an increase in the variance between market prices of the Fund’s shares and the Fund’s NAV. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices. 
It cannot be predicted whether Fund shares will trade below, at or above the Fund’s NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV when the Exchange re-opens. The Fund’s bid-ask spread and the resulting premium or discount to the Fund’s NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities. 
Authorized Participant Risk.  The Fund may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund’s shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to NAV and possibly face delisting.

PURCHASE AND SALE OF FUND SHARES
The Fund is an actively-managed ETF. Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called “Creation Units” through APs. The Adviser may modify the Creation Unit size with prior notification to the Fund’s APs. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund’s NAV. As a result, you may pay more than NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.
Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Historical information regarding the Fund’s bid/ask spread can be accessed on the Fund’s website at janushenderson.com/performance by selecting the Fund.
 
TAX INFORMATION
The Fund’s distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.
 
PAYMENTS TO BROKER‑DEALERS AND OTHER FINANCIAL INTERMEDIARIES
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

ADDITIONAL INFORMATION ABOUT THE FUNDS
 
 
 
FEES AND EXPENSES
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended October 31, 2022.
 
 
“Annual Fund Operating Expenses” are paid out of a Fund’s assets. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
 
 
The “Management Fee” is the rate paid by each Fund to the Adviser for providing certain services. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
 
 
“Other Expenses”
  °  
include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, business development companies (“BDCs”) and exchange-traded funds (“ETFs”)) in which a fund invests or has invested during the period. If applicable, or unless otherwise indicated in the Fund’s Fees and Expenses table, such amounts are less than 0.01% and are included in the Fund’s “Other Expenses.”
 
ADDITIONAL INVESTMENT STRATEGIES AND GENERAL PORTFOLIO POLICIES
The Funds are actively managed ETFs and, thus, do not seek to replicate the performance of a specified index. Accordingly, the portfolio managers have discretion on a daily basis to manage the Funds’ portfolios in accordance with each Fund’s investment objective.
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days or as soon as reasonably practicable before making any such change it considers material. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
On each business day before commencement of trading in shares on the Exchange, each Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV per share. A description of each Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio holdings is available in the Fund’s SAI. Information about the premiums and discounts at which each Fund’s shares have traded is available at janushenderson.com/performance by selecting the Fund for additional details.
Unless otherwise stated, the following additional investment strategies and general policies apply to each Fund and provide further information including, but not limited to, the types of securities the Fund may invest in when implementing its investment objective. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. Except for each Fund’s policies with respect to investments in illiquid investments, borrowing and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit, other than illiquid investments, borrowing and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Each Fund may borrow to the extent permitted by the Investment Company Act of 1940, as amended (the “1940 Act”). At times, a Fund may be required to segregate or earmark certain assets determined to be liquid by the Adviser to cover borrowings. For temporary liquidity and cash management purposes, the Funds may invest in other ETFs that provide exposure that is consistent with each Fund’s respective investment objective.
Security Selection
In selecting investments, Janus Henderson International Sustainable Equity ETF’s and Janus Henderson U.S. Sustainable Equity ETF’s portfolio managers employ a “bottom-up” approach that focuses on fundamental research. To identify the universe of investible securities for the Fund, the portfolio managers first employ positive selection criteria to identify companies that fall within at least one of ten environmental and social themes. Environmental themes include efficiency, cleaner energy,
 
21½Janus Detroit Street Trust

water management, environmental services, and sustainable transport. Social themes include sustainable property and finance, safety, quality of life, knowledge and technology, and health.
In selecting investments, the portfolio managers will then consider, among other factors, a company’s growth potential, competitive positioning, operational quality, and strategy. The portfolio managers may also consider factors such as a company’s historic and projected return on capital, balance sheets, and financial models. The portfolio managers will also consider environmental, social, and governance (“ESG”) factors including, but not limited to, climate change, deforestation, biodiversity, human rights, company culture, and community relations, board structure and diversity, executive pay, and corporate reporting.
The portfolio managers seek to maintain a portfolio of securities that has a carbon footprint and carbon intensity that is at least 20% below each Fund’s respective benchmark index. At the portfolio managers’ discretion, the Fund will engage with a company’s management regarding matters that may include shareholder rights, governance and remuneration, climate change, carbon emissions, pollution, biodiversity, human capital, and diversity and inclusion.
The portfolio managers evaluate and apply ESG and sustainable investment criteria relying on a mix of third-party data and internally-generated analyses based on information that may include web-based research reports from a company or independent sources, as well as corporate engagement. The portfolio managers do not apply ESG and sustainable investment criteria in managing the Fund’s exposure to cash and cash equivalents. The Funds will generally consider selling a stock if, in the portfolio managers’ opinion, there has been a regulatory, industry, or position-level change that may impair a company’s revenue growth. The Funds will also consider selling a stock if, in the portfolio managers’ opinion, the company’s business model no longer meets the sustainable investment criteria employed in managing the Funds.
In deciding to add or reduce portfolio positions, for Janus Henderson Net Zero Transition Resources ETF, the portfolio managers employ a “bottom-up” approach that focuses on fundamental research and considers, among other factors, a company’s growth potential, competitive positioning and operational quality, return on capital, risk profile, and strategy. Except as noted below, in selecting each investment, the portfolio managers will also consider ESG factors such as carbon footprint, corporate governance, human capital and diversity, and business ethics. The portfolio managers evaluate and apply ESG factors relying on a mix of third-party data and internally-generated analyses based on information that may include web-based research reports from a company or independent sources, as well as corporate engagement, and may sell a portfolio position if, in the portfolio managers’ opinion, the company’s business model no longer satisfies the ESG factors. The portfolio managers do not apply these ESG factors in managing the Fund’s cash and cash equivalents.
All Funds
The portfolio managers apply broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that, in the determination of the Adviser, are significantly engaged in or derive more than de minimis revenue from (generally no more than 5-10%), industries, activities, or assets considered by the portfolio managers to have a negative impact on society or the environment.
In screening such investments, there may be instances where the de minimis limits cannot be expressed quantitatively, in which case the portfolio managers apply a qualitative assessment of an issuer. Among other things, the qualitative assessment looks at the extent to which an “avoided” activity is part of a company’s business, whether a company is taking action to address and improve upon such activity, and may consider certain issuers, industries or sectors that are in the process of transitioning to sustainable business practices, in which case a threshold of greater than 5-10% may initially be applied.
A current list of such activities, which may evolve over time, follows:

Cash Position
The Funds may not always stay fully invested. For example, when the portfolio managers believe that market conditions are unfavorable for investing, or when they are otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments, such as commercial paper, repurchase agreements and other short-duration fixed-income securities, and/or affiliated or non-affiliated money market funds (or unregistered cash management pooled investment vehicles that operate as money market funds), may increase. Due to differing investment strategies, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, a Fund may take positions that are inconsistent with its investment policies. As a result, a Fund may not achieve its investment objective.
Emerging Markets
Within the parameters of their specific investment policies, the Funds may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets IndexSM.
 
23½Janus Detroit Street Trust

Exchange-Traded Funds
Each Fund may invest in ETFs, including affiliated ETFs. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of each Fund, which will be indirectly paid by each Fund. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in underlying ETFs and may be higher than other ETFs or mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the NAV of their underlying investments, there may be times when ETFs trade at a premium or discount. In the case of affiliated ETFs, unless waived, the Adviser will earn fees both from such Fund and from the underlying ETF, with respect to assets of the Fund invested in the underlying ETF. Each Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
The Funds may invest in foreign securities. The portfolio managers seek investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. The Funds may at times have significant foreign exposure, including exposure to emerging markets.
Illiquid Investments
A Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
Nondiversification
Diversification is a way to reduce risk by investing in a broad range of stocks or other securities. Janus Henderson Net Zero Transition Resources ETF is classified as nondiversified. A Fund that is classified as nondiversified has the ability to take larger positions in securities than a fund that is classified as diversified. This gives a Fund which is classified as nondiversified more flexibility to focus its investments in companies that the portfolio managers have identified as the most attractive for the investment objective and strategy of the Fund. However, because the appreciation or depreciation of a single security may have a greater impact on the NAV of a Fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified. This fluctuation, if significant, may affect the performance of a Fund.
Portfolio Turnover
In general, each Fund intends to purchase securities for long-term investment, although, to a limited extent, a Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to purchases and redemptions of Creation Units), the nature of a Fund’s investments, and the investment style of the portfolio managers.
Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
REITs and Real Estate-Related Securities
A Fund may invest in equity and debt securities of real estate-related companies. Such companies may include those in the real estate industry or real estate-related industries. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operation companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may
 
24½Janus Detroit Street Trust

also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITS, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Sustainable Investing
Sustainable investing is an investment approach that focuses on companies that relate to certain sustainable development themes, including those that are strategically aligned with environmental and social megatrends such as climate change, resource constraints, growing populations, and aging populations.
 
RISKS OF THE FUNDS
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The following information is intended to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater a Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Affiliated Underlying Fund Risk.  The Adviser may invest in certain affiliated ETFs as investments for each Fund. The Adviser will generally receive fees for managing such funds, in addition to the fees paid to the Adviser by each Fund. The payment of such fees by affiliated funds creates a conflict of interest when selecting affiliated funds for investment in a Fund. The Adviser, however, is a fiduciary to each Fund and its shareholders and is legally obligated to act in its best interest when selecting affiliated funds. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of such Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any of the affiliated ETFs with respect to such Fund’s investment in such ETF, less certain operating expenses.
Cash Transaction Risk.  The Funds may require all APs to purchase Creation Units in cash when the portfolio managers believe it is in the best interest of the Funds. Cash purchases may cause a Fund to incur portfolio transaction fees or charges or delays in investing the cash that it would otherwise not incur if a purchase was made on an in-kind basis. To the extent a Fund determines to effect a Creation Unit redemption on a cash basis, it may be less tax-efficient for the Fund compared to an in-kind redemption and may cause the Fund to incur portfolio transaction fees or charges it would not otherwise incur with an in-kind redemption, to the extent such fees or charges are not offset by the redemption transaction fee paid by APs. In addition, a Fund’s use of cash transactions may result in wider bid-ask spreads in Fund shares trading in the secondary market as compared to ETFs that transact exclusively on an in-kind basis.
Currency Risk.  Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as each Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When each Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Depositary Receipts Risk.  Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency.
 
25½Janus Detroit Street Trust

Emerging Markets Risk.  Within the parameters of their specific investment policies, the Funds may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and NAV may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets. Similarly, issuers in such markets may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which U.S. companies are subject. Information about emerging markets companies, including financial information, may be less available or reliable and the Fund’s ability to conduct due diligence with respect to such companies may be limited. In addition, certain emerging market jurisdictions materially restrict the Public Company Accounting Oversight Board’s (“PCAOB”) inspection, investigation, and enforcement capabilities which impairs the ability to conduct independent oversight or inspection of accounting firms located in, or operating in, certain emerging markets; therefore, there is no guarantee that the quality of financial reporting or the audits conducted by audit firms of emerging market issuers meet PCAOB standards. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. Moreover, the legal remedies for investors in emerging markets may be more limited than the remedies available in the United States and the ability of U.S. authorities (e.g., the SEC and the U.S. Department of Justice) to bring actions against bad actors may be limited. A shareholder’s ability to bring and enforce legal actions emerging market countries, or to obtain information needed to pursue or enforce such actions, may be limited and as a result such claims may be difficult or impossible to pursue. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
Eurozone Risk.  A number of countries in the European Union (“EU”) have experienced, and may continue to experience, severe economic and financial difficulties. In particular, many EU nations are susceptible to economic risks associated with high levels of debt, notably due to investments in sovereign debt. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries. As a result, financial markets in the EU have been subject to increased volatility and declines in asset values and liquidity. Responses to these financial problems by European governments, central banks, and others, including austerity measures and reforms, may not work, may result in social unrest, and may limit future growth and economic recovery or have other unintended consequences. All of these developments may continue to significantly affect the economies of all EU countries, which in turn may have a material adverse effect on a Fund’s investments in such countries, other countries that depend on EU countries for significant amounts of trade or investment, or issuers with exposure to debt issued by certain EU countries.
Exchange-Traded Funds Risk.  Each Fund may invest in ETFs, including affiliated ETFs. ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the NAV of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its NAV. When a Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in the Funds may be higher than the cost of investing directly in the underlying ETFs and may be higher than other ETFs or mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, the Fund may not be
 
26½Janus Detroit Street Trust

able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which a Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, a Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because a Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.
Foreign Exposure Risk.  The Funds may invest in foreign equity and/or debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity are located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:
 
 
Currency Risk.  As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
 
 
Political and Economic Risk.  Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the United States government on other countries or persons or issuers operating in such countries could restrict a Fund’s ability to buy affected securities or force a Fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, a Fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
 
     Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
 
 
Regulatory Risk.  There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
 
 
Foreign Market Risk.  Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.
 
 
Geographic Concentration Risk.  To the extent that a Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country
 
27½Janus Detroit Street Trust

 
or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.
 
 
Transaction Costs.  Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
Inflation Risk.  Inflation creates uncertainty over the future real value of an investment (the value after adjusting for inflation). The real value of certain assets or real income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of a Fund’s assets and distributions may decline. This risk is more prevalent with respect to debt securities held by a Fund. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy. Moreover, a Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders or adversely affect the real value of shareholders’ investment in a Fund. Fund shareholders’ expectation of future inflation can also impact the current value of a Fund’s portfolio, resulting in lower asset values and potential losses. This risk may be elevated compared to historical market conditions because of recent monetary policy measures and the current interest rate environment.
Issuer Concentration Risk.  A Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by a Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, a Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments.
Industry and Sector Risk.  Although each Fund does not concentrate its investments in specific industries or industry sectors, it emphasizes certain themes and megatrends. As a result, at times, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector or that benefit from the same megatrend. Companies in the same industry or economic sector or that benefit from the same megatrend may be similarly affected by economic or market events, making a Fund more vulnerable to unfavorable developments than funds that invest more broadly. As each Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
Liquidity Risk.  The Funds may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, the Funds may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, a Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect a Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that a Fund invests in restricted securities that are deemed to be illiquid investments.
Market Risk.  The value of a Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which a Fund invests. If the value of a Fund’s portfolio decreases, the Fund’s NAV will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, conflicts, including related sanctions, and social unrest, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
 
28½Janus Detroit Street Trust

 
COVID-19 Pandemic.  The effects of COVID-19 have contributed to increased volatility in global financial markets and have affected and may continue to affect certain countries, regions, issuers, industries and market sectors more dramatically than others. These conditions and events could have a significant impact on a Fund and its investments, a Fund’s ability to meet redemption requests, and the processes and operations of a Fund’s service providers, including the Adviser.
 
 
Russia/Ukraine Invasion.  Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions in the region are impossible to predict, but could be significant and have a severe adverse effect on the region, including significant negative impacts on the economy and the markets for certain securities and commodities, such as oil and natural gas, as well as other sectors.
Market Trading Risk.  The Funds are subject to secondary market trading risks. Shares of each Fund are listed for trading on an exchange; however, there can be no guarantee that an active trading market for such shares will develop or continue. Shares of a Fund may be listed or traded on U.S. and foreign exchanges other than the Fund’s primary U.S. listing exchange. There can be no guarantee that a Fund’s shares will continue trading on any exchange or in any market or that the Fund’s shares will continue to meet the listing or trading requirements of any exchange or market. A Fund’s shares may experience higher trading volumes on one exchange as compared to another and investors are subject to the execution and settlement risks of the market where their broker directs trades.
Secondary market trading in a Fund’s shares may be halted by an exchange because of market conditions. Pursuant to exchange or market rules, trading in a Fund’s shares on an exchange or in any market may be subject to trading halts caused by extraordinary market volatility. There can be no guarantee that a Fund’s exchange listing or ability to trade its shares will continue or remain unchanged. In the event a Fund ceases to be listed on an exchange, the Fund may cease operating as an “exchange-traded” fund and operate as a mutual fund, provided that shareholders are given advance notice.
Shares of a Fund may trade on an exchange at prices at, above, or below their most recent NAV. The per share NAV of a Fund is calculated at the end of each business day, as described below, and fluctuates with changes in the market value of the Fund’s holdings. The trading prices of a Fund’s shares fluctuate continuously throughout the trading day based on market supply and demand, and may not closely track NAV. The trading prices of a Fund’s shares may differ significantly from NAV during periods of market volatility, which may, among other factors, lead to the Fund’s shares trading at a premium or discount to NAV.
Buying or selling a Fund’s shares on an exchange may require the payment of brokerage commissions. In addition, you may also incur the cost of the spread (the difference between the bid price and the ask price). The commission is frequently a fixed amount and may be a significant cost for investors seeking to buy or sell small amounts of shares. The spread varies over time for shares of a Fund based on its trading volume and market liquidity, and is generally less if the Fund has more trading volume and market liquidity and more if the Fund has less trading volume and market liquidity. Due to the costs inherent in buying or selling a Fund’s shares, frequent trading may detract significantly from investment returns. Investment in a Fund’s shares may not be advisable for investors who expect to engage in frequent trading.
Nondiversification Risk.  Janus Henderson Net Zero Transition Resources ETF is classified as nondiversified under the 1940 Act, and therefore may hold a greater percentage of their assets in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s NAV and total return. Being nondiversified may also make the Fund more susceptible to financial, economic, political, or other developments that may impact a security. Although the Fund may satisfy the requirements for a diversified fund, the Fund’s nondiversified classification gives the Fund’s portfolio managers more flexibility to hold larger positions in securities than a fund that is classified as diversified. The Fund’s policy of concentrating its portfolio in a smaller number of holdings could result in more volatility in the Fund’s performance and share price. Since Janus Henderson Net Zero Transition Resources ETF normally invests primarily in a core portfolio of 35-60 equity securities, this risk may be increased.
Operational Risk.  An investment in each Fund can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in key personnel, technology and/or service providers, and errors caused by third party service providers. Among other things, these errors or failures, as well as other technological issues, may adversely affect each Fund’s ability to calculate its NAV, process fund orders, execute portfolio trades, or perform other essential tasks in a timely manner, including over a potentially extended period of time. These errors or failures may also result in a loss or compromise of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on each Fund. Implementation of business continuity plans by each Fund, the Adviser or third-party service providers in response to disruptive events such as natural disasters, epidemics and
 
29½Janus Detroit Street Trust

pandemics, terrorism, conflicts and social unrest may increase these operational risks to the Fund. While each Fund seeks to minimize such events through internal controls and oversight of third-party service providers, there is no guarantee that the Fund will not suffer losses if such events occur.
Portfolio Management Risk.  Each Fund is an actively managed investment portfolio and is therefore subject to the risk that the portfolio managers may not be successful in identifying investment opportunities that are aligned with the sustainable investment approach that a Fund employs. A Fund may underperform its benchmark index or other funds with similar investment objectives.
Private Placements and Other Restricted Securities Risk.  Investments in private placements and other restricted securities could decrease a Fund’s liquidity profile or prevent a Fund from disposing of them promptly at advantageous prices. Private placements and restricted securities may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. Transaction costs may be higher for these securities, and a Fund may get only limited information about the issuer of a private placement or other restricted security.
REIT Risk.  To the extent that a Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REITs and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which a Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. Each Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments, however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing the return to the Fund on its investment in such company.
Small- and Mid-Sized Companies Risk.  Each Fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, while small- and mid-sized companies may realize more substantial growth than larger or more established issuers, they may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on a Fund’s returns, especially as market conditions change.
Sustainable Investment Risk.  The Funds follow a sustainable investment approach by investing in companies that relate to certain sustainable development themes and demonstrate adherence to ESG practices. Accordingly, a Fund may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Additionally, due to its exclusionary criteria, a Fund may not be invested in certain industries or sectors. As a
 
30½Janus Detroit Street Trust

result, the Fund may be overweight or underweight in certain industries or sectors relative to its benchmark index, which may cause the Fund’s performance to be more or less sensitive to developments affecting those sectors. In addition, because sustainable and ESG investing takes into consideration factors beyond traditional financial analysis, the investment opportunities for a Fund may be limited at times. Sustainability and ESG-related information provided by issuers and third parties, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable and ESG investing in the United States is still developing and future rules and regulations may require a Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to engage in sustainable and ESG practices may fall out of favor, which could potentially limit a Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable and/or ESG-related business practices, which may result in a Fund selling a security when it might otherwise be disadvantageous to do so. There is no guarantee that sustainable investments will outperform the broader market on either an absolute or relative basis.
Trading Issues Risk.  Although Fund shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in shares is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of a Fund will continue to be met or will remain unchanged or that the shares will trade with any volume, or at all. In addition, during periods of significant volatility, the liquidity of the underlying securities held by a Fund may affect the Fund’s trading prices. During a “flash crash,” the market prices of a Fund’s shares may decline suddenly and significantly. Such a decline may not reflect the performance of the portfolio securities held by a Fund. Flash crashes may cause APs and other market makers to limit or cease trading in a Fund’s shares for temporary or longer periods. Shareholders could suffer significant losses to the extent that they sell a Fund’s shares at these temporarily low market prices.
Transaction and Spread Risk.  Investors buying or selling Fund shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions can be a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for shares (the “bid” price) and the price at which an investor is willing to sell shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for shares based on trading volume and market liquidity, and is generally lower if a Fund’s shares have more trading volume and market liquidity and higher if the Fund’s shares have little trading volume and market liquidity. Further, increased market volatility and trading halts affecting any of a Fund’s portfolio securities may cause increased bid/ask spreads. Due to the costs of buying or selling shares, including bid/ask spreads, frequent trading of shares may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments.
Warrants and Rights Risk.  The price, performance and liquidity of warrants and rights to purchase equity securities are typically linked to the underlying stock. These instruments have many characteristics of convertible securities and, similarly, will react to variations in the general market for equity securities. Rights are similar to warrants, but normally have a short duration and are distributed directly by the issuer to its shareholders. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

MANAGEMENT OF THE FUNDS
 
 
 
INVESTMENT ADVISER
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. The Adviser is responsible for the day-to-day management of each Fund’s investment portfolio and furnishes continuous advice and recommendations concerning each Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of each Fund. The Adviser utilizes a personnel-sharing arrangement with its foreign (non-U.S.) affiliates, Janus Henderson Investors (Jersey) Limited (“HIJL”) and Janus Henderson Investors (Australia) Institutional Funds Management Limited (“JHIAIFML”) pursuant to which certain Janus Henderson employees, acting for HIJL and JHIAIFML may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for HIJL and JHIAIFML are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to each Fund on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
Each Fund may rely on the Securities and Exchange Commission’s (the “SEC”) exemptive and no action relief that permits the Adviser, subject to the approval of the Trustees, to appoint or replace affiliated and unaffiliated subadvisers to manage all or a portion of each Fund’s assets and enter into, amend, or terminate such subadvisory agreements without obtaining shareholder approval (a “manager-of-managers structure”).
Pursuant to the relief, the Adviser, with the approval of the Trustees, has the ultimate responsibility, subject to oversight by the Board, to oversee subadvisers and recommend their hiring, termination and replacement. The Adviser, subject to the review and oversight of the Trustees, has responsibility to: set each Fund’s overall investment strategy; evaluate, select and recommend subadvisers to manage all or a portion of each Fund’s assets; and implement procedures reasonably designed to ensure that each subadviser complies with each Fund’s investment goal, policies and restrictions. Subject to review and oversight by the Trustees, under the manager-of-managers structure, the Adviser will allocate and, when appropriate, reallocate each Fund’s assets among subadvisers and monitor and evaluate the subadvisers’ performance. The relief also permits each Fund to disclose subadvisers’ fees only in the aggregate in the SAI. In the event that the Adviser hires a new subadviser pursuant to the manager-of-managers structure, the affected Fund would provide shareholders with information about the new subadviser and subadvisory agreement within 90 days.
The Trustees and the initial shareholder of each Fund have approved the use of a manager-of-managers structure for each Fund.
 
MANAGEMENT EXPENSES
Each Fund uses a unitary fee structure, under which each Fund pays the Adviser a “Management Fee” in return for providing certain investment advisory, supervisory, and administrative services to each Fund, including the costs of transfer agency, custody, fund administration, legal, audit, and other services. The Adviser’s fee structure is designed to pay substantially all of each Fund’s expenses. However, each Fund bears other expenses which are not covered under the Management Fee which may vary and affect the total level of expenses paid by shareholders, such as distribution fees (if any), brokerage expenses or commissions, interest and dividends (including those relating to short positions (if any)), taxes, litigation expenses, acquired fund fees and expenses (if any), and extraordinary expenses.
Each Fund’s Management Fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the Management Fee and other expenses that such Fund must pay.

A discussion regarding the basis for the Trustees’ approval of each Fund’s investment advisory agreement is included in each Fund’s semiannual report (for the period ending April 30) to shareholders. You can request each Fund’s annual or semiannual reports (as they become available), free of charge, by contacting your broker-dealer, plan sponsor, or financial intermediary, or by contacting a representative at 1-800-668-0434. The reports are also available, free of charge, at janushenderson.com/info.
Expense Limitation
The Adviser has contractually agreed to waive and/or reimburse a portion of each Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated ETFs in which the Fund invests. Pursuant to this agreement, the waiver amount is equal to the amount of Fund assets invested in the affiliated ETF, multiplied by an amount equal to the current daily unitary management fee of the affiliated ETF less certain asset-based operating fees and expenses incurred on a per-fund basis and paid by the Adviser with respect to the affiliated ETF (including, but not limited to custody, sub-administration and transfer agency fees). The fee waiver agreement will remain in effect at least through February 29, 2024. The fee waiver agreement may be modified or terminated prior to this date only at the discretion of the Board of Trustees.

Information about the portfolio managers’ compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund(s) that they manage, is included in the Funds’ SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades.
In addition, from time to time, the Adviser or its affiliates may, subject to compliance with applicable law, purchase and hold shares of a Fund for their own accounts, or may purchase shares of a Fund for the benefit of their clients, including other Janus Henderson funds. Increasing each Fund’s assets may enhance the Fund’s profile with financial intermediaries and platforms, investment flexibility and trading volume. The Adviser and its affiliates reserve the right, subject to compliance with applicable law, to dispose of at any time some or all of the shares of a Fund acquired for their own accounts or for the benefit of their clients. A large sale of Fund shares by the Adviser or its affiliates could significantly reduce the asset size of each Fund, which might have an adverse effect on the Fund’s investment flexibility or trading volume. The Adviser considers the effect of redemptions on each Fund and other shareholders in deciding whether to dispose of its shares of the Fund.
The Adviser believes it has appropriately designed and implemented policies and procedures to mitigate these and other potential conflicts of interest. A further discussion of potential conflicts of interest and policies and procedures intended to mitigate them is contained in the Funds’ SAI.

OTHER INFORMATION
 
 
 
DISTRIBUTION OF THE FUND
Creation Units for the Funds are distributed by ALPS Distributors, Inc. (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

DIVIDENDSDISTRIBUTIONS AND TAXES
 
 
 
DISTRIBUTIONS
To avoid taxation of each Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually.
Distribution Schedule
Dividends from net investment income are generally declared and distributed to shareholders quarterly. Distributions of net capital gains are declared and distributed at least annually. Dividends may be declared and paid more frequently to comply with the distribution requirements of the Internal Revenue Code. The date you receive your distribution may vary depending on how your intermediary processes trades. Dividend payments are made through Depository Trust Company (“DTC”) participants and indirect participants to beneficial owners then of record with proceeds received from each Fund. Please consult your financial intermediary for details.
How Distributions Affect each Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of each Fund, regardless of how long the shares have been held. Undistributed income and net capital gains are included in each Fund’s daily NAV. A Fund’s NAV drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If a Fund’s NAV was $10.00 on December 30, the Fund’s NAV on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable fund do not increase the value of your investment and may create income tax obligations.
No dividend reinvestment service is provided by the Trust. Financial intermediaries may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of Fund shares for reinvestment of their dividend distributions. Beneficial owners should contact their financial intermediary to determine the availability and costs of the service and the details of participation therein. Financial intermediaries may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and net capital gains will be automatically reinvested in additional whole shares of a Fund purchased in the secondary market.
 
TAXES
As with any investment, you should consider the tax consequences of investing in each Fund. The following is a general discussion of certain federal income tax consequences of investing in a Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in a Fund. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by a Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied.
Dividends received from REITs, certain foreign corporations, and income received “in lieu of” dividends in a securities lending transaction generally will not constitute qualified dividend income. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by each Fund and capital gains from any sale or exchange of Fund shares. Each Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although each Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (“IRS”).
 
36½Janus Detroit Street Trust

Each Fund may derive “excess inclusion income” from certain equity interests in mortgage pooling vehicles either directly or through an investment in a U.S. REIT. Please see the Funds’ SAI for a discussion of the risks and special tax consequences to shareholders in the event a Fund realizes excess inclusion income in excess of certain threshold amounts.
Under 2017 legislation commonly known as the Tax Cuts and Jobs Act, “qualified REIT dividends” (i.e., ordinary REIT dividends other than capital gain dividends and portions of REIT dividends designated as qualified dividend income) are treated as eligible for a 20% deduction by noncorporate taxpayers. Each Fund may choose to pass through the special character of “qualified REIT dividends” to its shareholders, provided the Fund and the shareholder meet certain holding period requirements.
Taxes on Sales
Any time you sell the shares of a Fund in a taxable account, it is considered a taxable event. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility.
U.S. federal income tax withholding may be required on all distributions payable to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS that they are subject to backup withholding. The current backup withholding rate is applied.
For shares purchased and sold from a taxable account, your intermediary will report cost basis information to you and to the IRS. Your financial intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your financial intermediary’s default method, which is often the average cost method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by a Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes.
Certain fund transactions may involve futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. A Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
Each Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important for each Fund to meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in a partnership, however, it may be subject to state tax liabilities.
If a Fund redeems Creation Units in cash, it may recognize more capital gains than it will if it redeems Creation Units in-kind.
For additional information, see the “Income Dividends, Capital Gains Distributions, and Tax Status” section of the SAI.

SHAREHOLDERS GUIDE
 
 
 
Each Fund issues or redeems its shares at NAV per share only in Creation Units. Shares of each Fund are listed for trading on a national securities exchange and trade on the secondary market during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. There is no minimum investment. When buying or selling Fund shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and offered price in the secondary market on each purchase and sale transaction. Fund shares are traded on the Exchange under the trading symbol SXUS for Janus Henderson International Sustainable Equity ETF, JZRO for Janus Henderson Net Zero Transition Resources ETF and SSPX for Janus Henderson U.S. Sustainable Equity ETF. Share prices are reported in dollars and cents per share.
APs may acquire Fund shares directly from each Fund, and APs may tender their Fund shares for redemption directly to the Fund, at NAV per share, only in Creation Units and in accordance with the procedures described in the Funds’ SAI.
 
PRICING OF FUND SHARES
The per share NAV of each Fund is computed by dividing the total value of the Fund’s portfolio, less any liabilities, by the total number of outstanding shares of the Fund. Each Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“Business Day”). However, the NAV may still be calculated if trading on the NYSE is restricted, provided there is sufficient pricing information available for a Fund to value its securities, or as permitted by the SEC. Foreign securities held by a Fund, as applicable, may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not Business Days in the United States and on which you will not be able to purchase or sell the Fund’s shares.
Securities held by each Fund are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940 (the “1940 Act”) and approved by and subject to the oversight of the Trustees (“Valuation Procedures”). To the extent available, equity securities (including shares of ETFs) are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, if applicable, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The methodologies employed when fair valuing securities may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
The value of the securities of mutual funds held by each Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
All purchases, sales, or other account activity must be processed through your financial intermediary or plan sponsor.

DISTRIBUTION AND SERVICING FEES
Distribution and Shareholder Servicing Plan
The Trust has adopted a Distribution and Servicing Plan for shares of each Fund pursuant to Rule 12b-1 under the 1940 Act (the “Plan”). The Plan permits compensation in connection with the distribution and marketing of Fund shares and/or the provision of certain shareholder services. The Plan permits each Fund to pay the Distributor, or its designee, a fee for the sale and distribution and/or shareholder servicing of the shares at an annual rate of up to 0.25% of average daily net assets of the shares of each Fund (“12b-1 fee”). However, payment of a 12b-1 fee has not been authorized at this time.
Under the terms of the Plan, the Trust is authorized to make payments to the Distributor or its designee for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in each Fund.
The 12b-1 fee may only be imposed or increased when the Trustees determine that it is in the best interests of shareholders to do so. Because these fees are paid out of each Fund’s assets on an ongoing basis, to the extent that a fee is authorized and payments are made, over time they will increase the cost of an investment in the Fund. The 12b-1 fee may cost an investor more than other types of sales charges.
 
PAYMENTS TO FINANCIAL INTERMEDIARIES BY ADVISER OR ITS AFFILIATES
From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries for making certain funds available to their clients or otherwise distributing, promoting or marketing the funds. The Adviser or its affiliates also make payments to one or more intermediaries for information about transactions and holdings in the funds, such as the amount of fund shares purchased, sold or held through the intermediary and or its salespersons, the intermediary platform(s) on which shares are transacted and other information related to the funds. Payments made by the Adviser and its affiliates may eliminate or reduce trading commissions that the intermediary would otherwise charge its customers or its salespersons in connection with the purchase or sale of certain funds. Payment by the Adviser or its affiliates to eliminate or reduce a trading commission creates an incentive for salespersons of the intermediary to sell the Janus Henderson funds over other funds for which a commission would be charged. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different intermediaries. The Adviser may determine to make payments based on any number of factors or metrics. For example, the Adviser may make payments at year-end and/or other intervals in a fixed amount, an amount based upon an intermediary’s services at defined levels, an amount based upon the total assets represented by funds subject to arrangements with the intermediary, or an amount based on the intermediary’s net sales of one or more funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. The Adviser currently maintains asset-based agreements with certain intermediaries on behalf of the Trust. The amount of compensation paid by the Adviser varies from intermediary to intermediary. More information regarding these payments is contained in the Funds’ SAI.
With respect to non-exchange-traded Janus Henderson funds not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to selected brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via National Securities Clearing Corporation (“NSCC”) or other means) in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary.
In addition, the Adviser or its affiliates may also share certain marketing expenses with intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, and support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Janus Henderson funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-
 
39½Janus Detroit Street Trust

specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments, reimbursements and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other funds (or non-mutual fund investments), with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell shares of the Funds. Please contact your financial intermediary or plan sponsor for details on such arrangements.
 
PURCHASING AND SELLING SHARES
Shares of each Fund are listed for trading on a national securities exchange during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. However, there can be no guarantee that an active trading market will develop or be maintained, or that each Fund shares listing will continue or remain unchanged. Each Fund does not impose any minimum investment for shares of the Fund purchased on an exchange. Buying or selling each Fund’s shares involves certain costs that apply to all securities transactions. When buying or selling shares of each Fund through a financial intermediary, you may incur a brokerage commission or other charges determined by your financial intermediary. Due to these brokerage costs, if any, frequent trading may detract significantly from investment returns. In addition, you may also incur the cost of the spread (the difference between the bid price and the ask price). The commission is frequently a fixed amount and may be a significant cost for investors seeking to buy or sell small amounts of shares.
Shares of each Fund may be acquired through the Distributor or redeemed directly with the Fund only in Creation Units or multiples thereof, as discussed in the “Creation and Redemption of Creation Units” section of the Funds’ SAI. Once created, shares of each Fund generally trade in the secondary market in amounts less than a Creation Unit.
Each Fund’s primary listing exchange is NYSE Arca (the “Exchange”). The Exchange is open for trading Monday through Friday and is closed on the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
A Business Day with respect to each Fund is each day the Exchange is open. Orders from APs to create or redeem Creation Units will only be accepted on a Business Day. On days when the Exchange closes earlier than normal, each Fund may require orders to create or redeem Creation Units to be placed earlier in the day. In addition, to minimize brokerage and other related trading costs associated with securities that cannot be readily transferred in-kind, each Fund may establish early trade cut-off times for APs to submit orders for Creation Units, in accordance with the 1940 Act. See the Funds’ SAI for more information.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, social security number, and permanent street address to assist in verifying your identity. You may also be asked to provide additional documents that may help to establish your identity. Until verification of your identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if
 
40½Janus Detroit Street Trust

it is unable to verify your identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about your financial intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Continuous Offering
The method by which Creation Units of shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of shares are issued and sold by each Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “Securities Act”), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirements and liability provisions of the Securities Act. For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells the shares directly to customers or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.
Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3)(C) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the shares that are part of an unsold allotment within the meaning of Section 4(a)(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.
Book Entry
Shares of each Fund are held in book-entry form, which means that no stock certificates are issued. The DTC or its nominee is the record owner of all outstanding shares of each Fund and is recognized as the owner of all shares for all purposes.
Investors owning shares of each Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Funds. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other exchange-traded securities that you hold in book-entry or “street name” form.
Share Prices
The trading prices of each Fund’s shares in the secondary market generally differ from the Fund’s daily NAV per share and are affected by market forces such as supply and demand, economic conditions, and other factors. Information regarding the intra-day net asset value of each Fund is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are primarily listed or by market data vendors or other information providers. The intra-day net asset value calculations are estimates of the value of each Fund’s NAV per Fund share based on the current market value of the securities and/or cash included in the Fund’s intra-day net asset value basket. The intra-day net asset value does not necessarily reflect the precise composition of the current portfolio of securities and instruments held by each Fund at a particular point in time. Additionally, when current pricing is not available for certain portfolio securities, including foreign securities and certain debt securities, the intra-day indicative value may not accurately reflect the current market value of each Fund’s shares or the best possible valuation of the current portfolio. For example, the intra-day net asset value is based on quotes and closing prices from the securities’ local market and may not reflect events that occur subsequent to the local market’s close. Therefore, the intra-day net asset value should not be viewed as a “real-time” update of the NAV, which is computed only
 
41½Janus Detroit Street Trust

once a day. The intra-day net asset value is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities and instruments included in each Fund’s intra-day net asset value basket. Each Fund is not involved in, or responsible for, the calculation or dissemination of the intra-day net asset value and makes no representation or warranty as to its accuracy. An inaccuracy in the intra-day net asset value could result from various factors, including the difficulty of pricing portfolio instruments on an intra-day basis.
Premiums and Discounts
There may be differences between the daily market prices on secondary markets for shares of each Fund and its NAV. NAV is the price per share at which a Fund issues and redeems shares. See “Pricing of Fund Shares” above. The price used to calculate market returns (“Market Price”) of a Fund generally is determined using the midpoint between the highest bid and the lowest offer on the national securities exchange on which shares of the Fund are primarily listed for trading, as of the time that the Fund’s NAV is calculated. A Fund’s Market Price may be at, above, or below its NAV. The NAV of a Fund will fluctuate with changes in the market value of its portfolio holdings. The Market Price of a Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.
Premiums or discounts are the differences (expressed as a percentage) between the NAV and the Market Price of a Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a Fund is trading below the reported NAV, expressed as a percentage of the NAV. A discount or premium could be significant. Information regarding a Fund’s premium/discount to NAV for the most recently completed calendar year and the most recently completed calendar quarters since that calendar year end (or the life of the Fund, if shorter) is available at janushenderson.com/performance by selecting the Fund for additional details.
Bid/Ask Spread
Investors purchasing or selling shares of a Fund in the secondary market may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (the “bid”) and the lowest price a seller is willing to accept for shares of the Fund (the “ask”). The spread varies over time for shares of a Fund based on its trading volume and market liquidity, and is generally less if the Fund has more trading volume and market liquidity and more if the Fund has less trading volume and market liquidity. Historical information regarding a Fund’s spread over various periods of time can be accessed at janushenderson.com/performance by selecting the Fund for additional details.
Investments by Other Investment Companies
The Trust and Janus Investment Fund are part of the same “group of investment companies” for purposes of Section 12(d)(1)(G) of the 1940 Act.
Under the 1940 Act, purchases or acquisitions by each Fund of shares issued by registered investment companies (including other ETFs) and BDCs and the purchase or acquisition of Fund shares by registered investment companies, BDCs, and investment vehicles relying on Section 3(c)(1) or 3(c)(7) of the 1940 Act are subject to the restrictions set forth in Section 12(d)(1) of the 1940 Act, except where an exemption is available, including as provided in Sections 12(d)(1)(F) and (G) and Rule 12d1-4 thereunder. Rule 12d1-4 permits registered investment companies and BDCs to invest in Fund shares beyond the limits in Section 12(d)(1)(A), subject to certain terms and conditions, including that the registered investment company or BDC first enter into a written agreement with the Trust regarding the terms of the investment, among other conditions.
 
EXCESSIVE TRADING
Unlike traditional mutual funds, the frequent trading of Fund shares generally does not disrupt portfolio management, increase a Fund’s trading costs, lead to realization of capital gains by the Fund, or otherwise harm Fund shareholders. The vast majority of trading in Fund shares occurs on the secondary market. Because these trades do not involve a Fund, they do not harm the Fund or its shareholders. A few institutional investors, referred to as Authorized Participants, are authorized to purchase and redeem Fund shares directly with each Fund in Creation Units. Creation Unit transactions that are effected using securities (i.e., in kind) do not cause any of the harmful effects to the issuing fund (as previously noted). However, Creation Unit transactions effected using cash can potentially subject the Fund and its shareholders to those harmful effects. As a result, each Fund requires Authorized Participants to pay transaction fees to cover brokerage and certain related costs when purchasing or redeeming Creation Units. Those fees are designed to protect each Fund and its shareholders from the dilutive costs associated with frequent creation and redemption activity. For these reasons, the Trustees of each Fund have determined that it is not necessary
 
42½Janus Detroit Street Trust

to adopt policies and procedures to detect and deter frequent trading and market timing of Fund shares. However, each Fund’s policies and procedures regarding frequent purchases and redemptions may be modified by the Trustees at any time.
 
FUND WEBSITE & AVAILABILITY OF PORTFOLIO HOLDINGS INFORMATION
Each Business Day, each Fund’s portfolio holdings information is provided by its custodian or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market. In addition, on each Business Day before commencement of trading in shares on the Exchange, each Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV. Each Fund is also required to disclose its complete holdings as an exhibit to its reports on Form N-PORT within 60 days of the end of the first and third fiscal quarters, and in the annual report and semiannual report to Fund shareholders.
For additional information on these disclosures and the availability of portfolio holdings information, please refer to the Funds’ SAI.
 
SHAREHOLDER COMMUNICATIONS
Statements and Reports
Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor is responsible for providing annual and semiannual reports, including the financial statements of each Fund. These reports show each Fund’s investments and the market value of such investments, as well as other information about the Fund and its operations. Please contact your financial intermediary or plan sponsor to obtain these reports. Each Fund’s fiscal year ends October 31.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

GLOSSARY OF INVESTMENT TERMS
 
 
 
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
 
EQUITY AND DEBT SECURITIES
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Duration is a measurement of price sensitivity to interest rate changes. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by a Fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, the Fund’s duration is usually shorter than its average maturity. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter duration. For example, the price of a bond portfolio with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. The Fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise.
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are index-based investment companies which hold substantially all of their assets in securities with equity characteristics. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short- and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that the Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that the Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Private placements are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices
 
47½Janus Detroit Street Trust

of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Restricted securities are securities acquired through nonpublic transactions that have limitations on their resale. Restricted securities are unregistered and may only be resold under certain circumstances as noted in Rule 144A of the Securities Act of 1933, as amended.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year. Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
 
FUTURES, OPTIONS, AND OTHER DERIVATIVES
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities, and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities.
Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. The Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. The Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. The Fund may also buy options on futures contracts. An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures
 
48½Janus Detroit Street Trust

contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges.
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. The Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. The Fund may purchase or write such options individually or in combination.
 
OTHER INVESTMENTS, STRATEGIES, AND/OR TECHNIQUES
Diversification is a classification given to a fund under the Investment Company Act of 1940, as amended (the “1940 Act”). Funds are classified as either diversified or nondiversified. To be classified as diversified under the 1940 Act, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as nondiversified under the 1940 Act, on the other hand, has the flexibility to take larger positions in securities than a fund that is classified as diversified. However, because the appreciation or depreciation of a single security may have a greater impact on the NAV of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.
Industry concentration for purposes under the 1940 Act is the investment of 25% or more of a Fund’s total assets in an industry or group of industries.
Leverage is investment exposure which exceeds the initial amount invested. Leverage occurs when the Fund increases its assets available for investment using reverse repurchase agreements, derivatives, or other similar transactions. In addition, other investment techniques, such as short sales, can create a leveraging effect.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Net long is a term used to describe when the Fund’s assets committed to long positions exceed those committed to short positions.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Reverse repurchase agreements involve the sale of a security by the Fund to another party (generally a bank or dealer) in return for cash and an agreement by the Fund to buy the security back at a specified price and time. This technique may be used for investment purposes, which may have a leveraging effect on the Fund’s portfolio. This technique may also be used for other temporary or emergency purposes.
When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.
