Fund summary

Investment objective

Putnam PanAgora ESG International Equity ETF seeks long term capital appreciation.

Fees and expenses

The following tables describe the fees and expenses you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Example

The following hypothetical example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. It assumes that you invest $10,000 in the fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year and that the fund’s operating expenses remain the same. Your actual costs may be higher or lower.

Portfolio turnover

The fund pays transaction-related costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or the above example, affect fund performance. The fund’s portfolio turnover rate will be available after the fund completes its first fiscal year.

Principal investment strategies

The fund invests mainly in common stocks (growth or value stocks or both) of companies of any size outside the United States with a focus on companies that the fund’s subadviser, PanAgora Asset Management, Inc. (“PanAgora”), believes offer attractive benchmark-relative returns and exhibit positive environmental, social and governance (“ESG”) metrics. In evaluating and selecting investments for the fund, PanAgora employs a proprietary framework using quantitative models that

2     Prospectus



 



identify companies that offer above-market return potential based on their ESG metrics, together with other proprietary factors measuring a company’s financial and operational health, and then construct a portfolio that integrates return potential and ESG metrics.

PanAgora uses advanced statistical and machine learning techniques, together with third-party and proprietary data sources, in evaluating companies’ ESG metrics and return potential. Metrics designed to evaluate companies’ environmental practices may include third-party or proprietary data sources, including those regarding a company’s environmental footprint or its environmental efficiencies. Metrics designed to evaluate companies’ social practices may include third-party or proprietary data sources, including those regarding board diversity levels at a company. Metrics designed to evaluate companies’ governance practices may include third-party or proprietary data sources, including those regarding a company’s shareholder structure. Additionally, PanAgora’s quantitative model may also use third-party and/or proprietary data sources to identify companies exhibiting improved ESG profiles or those investing in ESG initiatives. The ESG metrics and information used in the portfolio construction process may change over time and may not be relevant to all companies that are eligible for investment by the fund.

Under normal circumstances, the fund invests at least 80% of its net assets in equity securities of companies that meet PanAgora’s ESG criteria. PanAgora will assign each company an ESG rating using proprietary ESG scores. In order to meet PanAgora’s ESG criteria, a company must have an ESG score above 0, reflecting more positive characteristics. A negative ESG score indicates a lower (or worse) rating. PanAgora assigns companies an ESG score that ranges from -2 to +2, although the range of scores may change over time. This policy is non-fundamental and may be changed only after 60 days’ notice to shareholders. PanAgora may not apply ESG criteria to investments that are not subject to the fund’s 80% policy and such investments may not meet PanAgora’s ESG criteria.

The fund’s equity investments may include common stocks, preferred stocks, convertible securities, warrants, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). The fund invests mainly in developed countries but may also invest in emerging markets.

PanAgora may consider, among other factors, a company’s valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell investments. While PanAgora may consider independent third-party data as a part of its analytical process, the portfolio management team performs its own independent analysis of issuers, through its quantitative model and proprietary scoring system, and does not rely solely on third-party screens.

From time to time, the fund may invest a significant portion of its assets in companies in one or more related industries or sectors. The fund may also invest a significant portion of its assets in one or more related geographic regions, such as European and Asian countries.

makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund’s shares or to submit purchase and redemption orders for creation units. The market prices of the fund’s shares are expected to fluctuate, in some cases materially, in response to changes in the fund’s NAV, the intraday value of the fund’s holdings and supply and demand for the fund’s shares. PanAgora cannot predict whether the fund’s shares will trade above, below or at their NAV or the intraday value of the fund’s holdings. During such periods, investors may incur significant losses if they sell shares.

The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund’s shares are listed. 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, fixing or settlement times, bid-ask spreads on the exchange and the corresponding premium or discount to the shares’ NAV may widen.

Purchase and sale of fund shares

Shares of the fund are listed and traded on an exchange, and individual fund shares may only be bought and sold in the secondary market through a broker or dealer at market price. These transactions, which do not involve the fund, are made at market prices that may vary throughout the day, rather than at net asset value (NAV). Shares of the fund may trade at a price greater than the fund’s NAV (premium) or less than the fund’s NAV (discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares (bid) and the lowest price a seller is willing to accept for shares (ask) when buying or selling fund shares in the secondary market (the “bid-ask spread”). Recent information, including information regarding the fund’s NAV, market price, premiums and discounts, and bid-ask spread, is available at putnam.com.

Tax information

The fund’s distributions will be taxed as ordinary income or capital gains unless you hold the shares through a tax-advantaged arrangement, in which case you will generally be taxed only upon withdrawal of monies from the arrangement.

Financial intermediary compensation

The fund and its related companies may pay intermediaries, which may include banks, broker/dealers, or financial professionals, for the sale of fund shares and related services. Please bear in mind that these payments may create a conflict of interest by influencing the broker/dealer or other intermediary to recommend the fund over another investment. Ask your advisor or visit your advisor’s website for more information.

The fund’s equity investments may include common stocks, preferred stocks, convertible securities, warrants, ADRs and GDRs. The fund invests mainly in developed countries but may also invest in emerging markets.

The fund may engage in a variety of transactions involving derivatives, such as forward contracts, futures, options, warrants and swap contracts although they do not represent a primary focus of the fund.

PanAgora may consider, among other factors, a company’s valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell investments.

Principal investment risks

The principal and certain additional risks of investing in the fund are described below. These risks and other factors may adversely affect the fund’s NAV, market price and performance. When you sell your shares, they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund may not achieve its investment objective, and it is not intended to be a complete investment program. The fund’s Statement of Additional Information (“SAI”) contains additional information about the fund’s investment policies and risks.

example, PanAgora may, in reliance on faulty models or data, be unsuccessful in its efforts to manage the fund’s overall level of volatility and its efforts to diversify risk. Any hedging based on faulty models and data may prove to be unsuccessful. In addition, models may incorrectly forecast future behavior, leading to potential losses on a cash flow and/or mark-to-market basis. Use of these models in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind) also may result in losses for the fund. All models require data. Some of the models that PanAgora may use are typically constructed based on historical data, and the success of these models is dependent largely on the accuracy and reliability of the supplied historical data. If incorrect data is entered into a model, the resulting output will be incorrect. As a result, any investment decisions made in reliance on the incorrect output from a model may not produce the desired results and the fund may realize losses. Even when data is correctly inputted into a model, the resulting information may differ, sometimes substantially, from other available data. For example, “model prices” that are provided by a model will often differ substantially from market prices, particularly for instruments that are complex in nature, such as derivatives. Models also rely on the proper functioning of hardware and technology, which are subject to disruption risk. There is no guarantee that the hardware and technology on which the models rely will be uninterrupted or error free, or that any defects in such hardware or technology will be able to be corrected in a short time period.

The market price of shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers, or other participants that trade the particular security. In times of severe market disruption or volatility, the bid/ask spread can increase significantly. At those times, shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of shares is falling fastest, which may be the time that you most want to sell your shares.

Only an authorized participant may engage in creation or redemption transactions directly with the fund. There is no guarantee that the fund will be able to attract market makers and authorized participants. There are no obligations of market makers to make a market in the fund’s shares or of authorized participants to submit purchase or redemption orders for creation units.

The market prices of the fund’s shares are expected to fluctuate, in some cases materially, in response to changes in the fund’s NAV, the intraday value of the fund’s holdings and supply and demand for the fund’s shares. PanAgora cannot predict whether the fund’s shares will trade above, below or at their NAV or the intraday value of the fund’s holdings. During such periods, investors may incur significant losses if they sell shares.

The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund’s shares are listed. 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, fixing or settlement times, bid-ask spreads on the exchange and the corresponding premium or discount to the shares’ NAV may widen.

In addition, trading of shares in the secondary market may be halted, for example, due to activation of market-wide “circuit breakers.” If trading halts or an unanticipated early closing of the listing exchange occurs, a shareholder may be unable to purchase or sell shares of the fund.

If the fund’s shares are delisted from the listing exchange, PanAgora may seek to list the fund shares on another market, merge the fund with another exchange-traded fund or traditional mutual fund, or redeem the fund shares at NAV.

Shares of the fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short.

experience high levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices. These risks may be exacerbated during economic downturns or other periods of economic stress.

The novel coronavirus (“COVID-19”) pandemic and efforts to contain its spread have negatively affected, and are likely to continue to negatively affect, the global economy, the economies of the United States and other individual countries, and the financial performance of individual issuers, sectors, industries, asset classes, and markets in significant and unforeseen ways. The COVID-19 pandemic has resulted in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, and economic downturns and recessions, and these effects may continue for an extended period of time and may increase in severity over time. In addition, actions taken by governmental and quasi-governmental authorities and regulators throughout the world in response to the COVID-19 pandemic, including significant fiscal and monetary policy changes, may affect the value, volatility, and liquidity of some securities and other assets. Given the significant uncertainty surrounding the magnitude, duration, reach, costs and effects of the COVID-19 pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, it is difficult to predict its potential impacts on the fund’s investments. The effects of the COVID-19 pandemic also are likely to exacerbate other risks that apply to the fund, including the risks disclosed in this prospectus, which could negatively impact the fund’s performance and lead to losses on your investment in the fund.

reliant on only a few industries or commodities. In Japan, the economy is strongly impacted by government intervention and protectionism, as well as international trade, government support of the financial services sector and other troubled sectors, and geopolitical developments. Japan, as well as the other Asian countries, has historically been prone to natural disasters. The occurrence of a natural disaster, including subsequent recovery from a natural disaster, in the region could negatively impact the economy of the affected country or countries. Certain developing economies in Asia are characterized by frequent currency fluctuations, devaluations, and restrictions; unstable employment rates; rapid fluctuation in, among other things, inflation and reliance on exports; and less efficient markets. Currency fluctuations or devaluations in any one country can have a significant effect on the entire region.

Growth stocks — Stocks of companies PanAgora believes are fast-growing may trade at a higher multiple of current earnings than other stocks. The values of these stocks may be more sensitive to changes in current or expected earnings or heightened levels of inflation than the values of other stocks. If PanAgora’s assessment of the prospects for a company’s earnings growth is wrong, or if PanAgora’s judgment of how other investors will value the company’s earnings growth is wrong, then the price of the company’s stock may fall or may not approach the value that PanAgora has placed on it. In addition, growth stocks, at times, may not perform as well as value stocks or the stock market in general, and may be out of favor with investors for varying periods of time.

Value stocks — Companies whose stocks PanAgora believes are undervalued by the market may have experienced adverse business developments or may be subject to special risks that have caused their stocks to be out of favor. If PanAgora’s assessment of a company’s prospects is wrong, or if other investors do not similarly recognize the value of the company, then the price of the company’s stock may fall or may not approach the value that PanAgora has placed on it. In addition, value stocks, at times, may not perform as well as growth stocks or the stock market in general, and may be out of favor with investors for varying periods of time.

Unfavorable changes in currency exchange rates: Foreign investments are typically issued and traded in foreign currencies. As a result, their values may be affected by changes in exchange rates between foreign currencies and the U.S. dollar.
Political and economic developments: Foreign investments may be subject to the risks of seizure by a foreign government, direct or indirect impact of sovereign debt default, imposition of economic sanctions, tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures taken in response to such actions), and tax increases.
Unreliable or untimely information: There may be less publicly-available information, or less reliable publicly-available information, about foreign companies (including information related to companies' ESG practices), particularly with respect to emerging market companies, than about most publicly-traded U.S. companies, and foreign companies are usually not subject to accounting, auditing and financial reporting standards and practices as stringent as those in the United States. As a result, the fund’s ability to evaluate a foreign company, including with respect to its ESG or sustainability practices, may be more limited than its ability to evaluate a U.S. company. Foreign securities may trade on markets that are closed when U.S. markets are open. As a result, accurate pricing information based on foreign market prices may not always be available.
Limited legal recourse: Legal remedies for investors may be more limited than the remedies available in the United States.
Limited markets: Certain foreign investments may be less liquid (harder to buy and sell) and more volatile than most U.S. investments, which means PanAgora may at times be unable to sell these foreign investments at desirable prices. For the same reason, PanAgora may at times find it difficult to value the fund’s foreign investments.
Trading practices: Brokerage commissions and other fees are generally higher for foreign investments than for U.S. investments. The procedures and rules governing foreign transactions and custody may also involve delays in payment, delivery or recovery of money or investments.

The risks of foreign investments are typically increased in countries with less developed markets, which are sometimes referred to as emerging markets. Emerging markets may have less developed economies and legal and regulatory systems, and may be susceptible to greater political and economic instability than developed foreign markets. Countries with emerging markets are also more likely to experience high levels of inflation or currency devaluation, and investments in emerging markets may be more volatile and less liquid than investments in developed markets. For these and other reasons, investments in emerging markets are often considered speculative.

Certain risks related to foreign investments may also apply to some extent to U.S.-traded investments that are denominated in foreign currencies, investments in U.S. companies that are traded in foreign markets or investments in U.S. companies that have significant foreign operations.

Derivatives involve special risks and may result in losses. The successful use of derivatives depends on PanAgora’s ability to manage these sophisticated instruments. Some derivatives are “leveraged,” which means they provide the fund with investment exposure greater than the value of the fund’s investment in the derivatives. As a result, these derivatives may magnify or otherwise increase investment losses to the fund. The risk of loss from certain short derivatives positions is theoretically unlimited. The value of derivatives may move in unexpected ways due to unanticipated market movements, the use of leverage, imperfect correlation between the derivative instrument and the reference asset, or other factors, especially in unusual market conditions, and volatility in the value of derivatives could adversely affect the fund’s returns, obligations and exposures. Other risks arise from the potential inability to terminate or sell derivatives positions. Derivatives may subject the fund to liquidity risk due to the obligation to make payments of margin, collateral, or settlement payments to counterparties. A liquid secondary market may not always exist for the fund’s derivatives positions. In fact, certain over-the-counter instruments (investments not traded on an exchange) may not be liquid. Over-the-counter instruments also involve the risk that the other party to the derivative transaction may not be willing or able to meet its obligations with respect to the derivative transaction. The risk of a party failing to meet its obligations may increase if the fund has significant exposure to that counterparty. Derivative transactions may also be subject to operational risk, including due to documentation and settlement issues, system failures, inadequate controls and human error and legal risk due to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of the derivative contract. For further information about additional types and risks of derivatives, see Miscellaneous Investments, Investment Practices and Risks in the SAI.

Other investments

In addition to the main investment strategies described above, the fund may also invest in cash or cash equivalents, including money market instruments or short-term instruments such as commercial paper, bank obligations (e.g., certificates of deposit and bankers’ acceptances), repurchase agreements, and U.S. Treasury bills or other government obligations. The fund may also from time to time invest a portion of its cash balances in money market and/or short-term bond funds advised by PanAgora or its affiliates. The percentage of the fund invested in cash and cash equivalents and such money market and short-term bond funds is expected to vary over time and will depend on various factors, including market conditions, purchase and redemption activity by fund shareholders, and PanAgora’s assessment of the cash level that is appropriate to allow the fund to pursue investment opportunities as they arise and to meet shareholder redemption requests. Large cash positions may dampen performance and may prevent the fund from achieving its goal. These practices may be subject to other risks, as described under Miscellaneous Investments, Investment Practices and Risks in the SAI.

Temporary defensive strategies

In response to adverse market, economic, political or other conditions, PanAgora may take temporary defensive positions, such as investing some or all of the fund’s assets in cash and cash equivalents that differ from the fund’s usual investment strategies. However, PanAgora may choose not to use these temporary defensive strategies for a variety of reasons, even in very volatile market conditions. If PanAgora does employ these strategies, the fund may miss out on investment opportunities and may not achieve its goal. Additionally, while temporary defensive strategies are mainly designed to limit losses, they may not work as intended.

Fund management

Investment manager

The Trustees have retained Putnam Management, which has managed mutual funds since 1937, to be the fund’s investment manager, responsible for making investment decisions for the fund and managing the fund’s other affairs and business.

The fund pays an annual all-inclusive management fee of 0.49% to Putnam Management based on the fund’s average daily net assets. The management fee is calculated and accrued daily. The management fee covers all of the other expenses of the fund with limited exceptions.

Putnam Management’s address is 100 Federal Street, Boston, MA 02110.

Putnam Management has retained its affiliate PanAgora to make investment decisions for such fund assets as may be designated from time to time for its management by Putnam Management. Putnam Management (and not the fund) pays a quarterly sub-advisory fee to PanAgora for its services at the annual rate of 0.17% of the average net asset value of the fund.

PanAgora is located at One International Place, 24th Floor, Boston, Massachusetts 02210.

Shareholder information

Valuation of fund shares

The price of the fund’s shares is based on its NAV. The NAV per share of each class equals the total value of its assets, less its liabilities, divided by the number of its outstanding shares. Shares are only valued as of the scheduled close of regular trading on the NYSE each day the exchange is open.

The fund values its investments for which market quotations are readily available at market value. It values all other investments and assets at their fair value, which may differ from recent market prices. For example, the fund may value a stock at its fair value when the relevant exchange closes early or trading in the stock is suspended. It may also value a stock at fair value if recent transactions in the stock have been very limited or if, in the case of a security traded on a market that closes before the NYSE closes, material information about the issuer becomes available after the close of the relevant market.

20     Prospectus



 



The fund translates prices for its investments quoted in foreign currencies into U.S. dollars at current exchange rates, which are generally determined as of 4:00 p.m. Eastern Time each day the NYSE is open. As a result, changes in the value of those currencies in relation to the U.S. dollar may affect the fund’s NAV. Because foreign markets may be open at different times than the NYSE, the value of the fund’s shares may change on days when shareholders are not able to buy or sell them. Many securities markets and exchanges outside the U.S. close before the close of the NYSE, and the closing prices for securities in those markets or exchanges may not reflect events that occur after the close but before the scheduled close of regular trading on the NYSE. As a result, the fund has adopted fair value pricing procedures, which, among other things, require the fund to fair value foreign equity securities if there has been a movement in the U.S. market that exceeds a specified threshold. Although the threshold may be revised from time to time and the number of days on which fair value prices will be used will depend on market activity, it is possible that fair value prices will be used by the fund to a significant extent. As noted above, the value determined for an investment using the fund’s fair value pricing procedures may differ from recent market prices for the investment.

Additional information about the fund

The fund is an actively managed ETF. Like other ETFs, shares of the fund are generally purchased and redeemed in creation unit aggregations through authorized participants, shares of the fund are listed and traded on a stock exchange, and individual investors can purchase or sell shares in less than creation unit sizes and for cash in the secondary market through a broker.

Derivative actions

The fund is a series of Putnam ETF Trust (the Trust). The Trust’s Amended and Restated Agreement and Declaration of Trust imposes certain conditions on derivative actions that are not otherwise required by law, including, in the case of any claim not arising under the federal securities laws, a requirement that the holders of 10% or more of the total outstanding shares of the applicable fund join the request to commence the action. Although these conditions are intended to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to a fund or its shareholders as a result of spurious shareholder demands and derivative actions, they may make it more difficult or costly for fund shareholders to bring derivative actions on behalf of the Trust.

Buying and selling shares in the secondary market

Shares of the fund are listed and traded on an exchange, and individual fund shares may only be bought and sold in the secondary market through a broker. The fund does not impose any minimum investment for shares of the fund purchased on an exchange. These transactions are made at market prices that may vary throughout the day and may be greater than the fund’s NAV (premium) or less than the fund’s NAV (discount). As a result, you may pay more than NAV when you purchase shares, and receive less than NAV when you sell shares, in the secondary market. If you buy

Prospectus    21



 



or sell shares in the secondary market, you will generally incur customary brokerage commissions and charges and you may also incur the cost of the spread between the price at which a dealer will buy fund shares and the somewhat higher price at which a dealer will sell shares. Due to such commissions and charges and spread costs, frequent trading may detract significantly from investment returns.

The fund is designed to offer investors an investment that can be bought and sold frequently in the secondary market without impact on the fund, and such trading activity is designed to enable the market price of fund shares to remain at or close to NAV. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive or short-term trading by these investors.

The fund accommodates frequent purchases and redemptions of creation units by authorized participants and does not place a limit on purchases or redemptions of creation units by these investors. The fund reserves the right, but does not have the obligation, to reject any purchase or redemption transaction (subject to legal and regulatory limits regarding redemption transactions) at any time. In addition, the fund reserves the right to impose restrictions on disruptive, excessive, or short-term trading.

Precautionary notes

Note to registered investment companies

Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in the securities of other investment companies, including shares of the fund. Registered investment companies are permitted to invest in the fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions, including that such investment companies enter into an agreement with the fund.

Note to authorized participants regarding continuous offering

Certain legal risks may exist that are unique to authorized participants purchasing creation units directly from the fund. Because new creation units may be issued on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act of 1933 (the Securities Act), could be occurring. As a broker-dealer, certain activities that you perform may, depending on the circumstances, result in your being deemed a participant in a distribution, in a manner which could render you a statutory underwriter and subject you to the prospectus delivery and liability provisions of the Securities Act.

For example, you may be deemed a statutory underwriter if you purchase creation units from the fund, break them down into individual fund shares, and sell such shares directly to customers, or if you choose to couple the creation of a supply of new fund shares with an active selling effort involving solicitation of secondary market demand for fund shares. A determination of whether a person is an underwriter for purposes of the Securities Act depends upon all of the facts and circumstances pertaining to that person’s activities, and the examples mentioned

here should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Dealers who are not “underwriters” but are participating in a distribution (as opposed to engaging in ordinary secondary market transactions), and thus dealing with shares as 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. This is because the prospectus delivery exemption in Section 4(a)(3) 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, you should note that dealers who are not underwriters but are participating in a distribution (as opposed to engaging in ordinary secondary market transactions) and thus dealing with the shares that are part of an overallotment within the meaning of Section 4(a)(3)(A) of the Securities Act would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. Firms that incur a prospectus-delivery obligation with respect to shares of the fund are reminded that, under Rule 153 under the Securities Act, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on an exchange is satisfied by the fact that the prospectus is available at the exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

Certain affiliates of the fund may purchase and resell fund shares pursuant to this prospectus.

Note to secondary market investors

The Depository Trust Company (DTC), a limited trust company and securities depository that facilitates the clearance and settlement of trades for its participating banks and broker-dealers, has executed an agreement with Foreside Fund Services, LLC (Foreside), the Fund’s distributor. DTC, or its nominee, is the registered owner of all outstanding shares of the fund. Putnam Management will not have any record of your ownership. Your ownership of shares will be shown on the records of DTC and the DTC participant broker through which you hold the shares. Your broker will provide you with account statements, confirmations of your purchases and sales, and tax information. Your broker will also be responsible for distributing income and capital gain distributions and for sending you shareholder reports and other information as may be required.

Costs associated with creations and redemptions

The fund generally imposes a creation transaction fee and a redemption transaction fee to offset transfer and other transaction costs associated with the issuance and redemption of creation units of shares. Information about the procedures regarding creation and redemption of creation units and the applicable transaction fees is included in the SAI.

Distribution plans and payments to intermediaries

Principal distributor

Foreside distributes creation units for the fund on an agency basis, does not maintain a secondary market in shares of the fund, and has no role in determining the investment policies of the fund or the securities that are purchased or sold by the fund. Foreside is not affiliated with Putnam Management, PIL, or any other service provider for the fund.

Foreside’s address is Three Canal Plaza, Suite 100, Portland, ME 04101.

Intermediaries may receive from Putnam Management, Foreside, and/or their respective affiliates compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses, and compensation for services intended to result in the sale of fund shares. These payments are described in more detail in this section and in the SAI.

Distribution and service plan

The fund has adopted a distribution and service plan pursuant to Rule 12b-1 under the 1940 Act that authorizes the fund to pay distribution fees in connection with the sale and distribution of its shares and service fees in connection with the provision of ongoing shareholder support services. No Rule 12b-1 fees are currently paid by the fund, and there are no current plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, because these fees are paid out of the fund’s assets on an ongoing basis, these fees will increase the cost of your investment in the fund.

No dealer, sales representative, or any other person has been authorized to give any information or to make any representations, other than those contained in this prospectus and in the related SAI, in connection with the offer contained in this prospectus. If given or made, such other information or representations must not be relied upon as having been authorized by the fund or Foreside. This prospectus and the related SAI do not constitute an offer by the fund or by Foreside to sell shares of the fund to or to buy shares of the fund from any person to whom it is unlawful to make such offer.

Payments to intermediaries

Investors may purchase shares of the fund on an exchange through intermediaries (including any broker, intermediary, bank, bank trust department, registered investment advisor, financial planner, retirement plan administrator and any other institution that offers shares of the fund to its customers). In addition to distribution and service plans, Putnam Management and its affiliates may make payments to intermediaries that do not increase your fund expenses, as described below.

Putnam Management and its affiliates also pay additional compensation to selected intermediaries in recognition of their marketing support and/or program servicing (each of which is described in more detail below). These payments may create an

24     Prospectus



 



incentive for an intermediary firm or its representatives to recommend or offer shares of the fund or other Putnam funds to its customers. These additional payments are made by Putnam Management and its affiliates and do not increase the amount paid by you or the fund as shown under Fund summary — Fees and expenses. The additional payments to intermediaries by Putnam Management and its affiliates are generally based on one or more of the following factors: average net assets of a fund attributable to that intermediary, sales or net sales of a fund attributable to that intermediary, or reimbursement of ticket charges (fees that an intermediary firm charges its representatives for effecting transactions in fund shares), or on the basis of a negotiated lump sum payment for services provided.

Marketing support payments are generally available to most intermediaries engaging in significant sales of Putnam fund shares. These payments are individually negotiated with each intermediary firm, taking into account the marketing support services provided by the intermediary, including business planning assistance, educating intermediary personnel about the Putnam funds and shareholder financial planning needs, placement on the intermediary’s preferred or recommended fund company list, access to sales meetings, sales representatives and management representatives of the intermediary, market data, as well as the size of the intermediary’s relationship with Putnam Management.

Program servicing payments, which are paid in some instances to intermediaries in connection with investments in the fund through intermediary platforms and other investment programs. These payments are made for program or platform services provided by the intermediary, including shareholder recordkeeping, reporting, or transaction processing, as well as services rendered in connection with intermediary platform development and maintenance, fund/investment selection and monitoring, or other similar services.

You can find a list of all intermediaries to which Putnam made marketing support and/ or program servicing payments in the SAI, which is on file with the SEC and is also available on Putnam’s website at putnam.com. You can also find other details in the SAI about the payments made by Putnam Management and its affiliates and the services provided by your intermediary. Your intermediary may charge you fees or commissions in addition to those disclosed in this prospectus. You can also ask your intermediary about any payments it receives from Putnam Management and its affiliates and any services your intermediary provides, as well as about fees and/or commissions it charges.

Other payments

Putnam Management and its affiliates may make other payments (including payments in connection with educational seminars or conferences) or allow other promotional incentives to intermediaries to the extent permitted by SEC and NASD (as adopted by FINRA) rules and by other applicable laws and regulations.

Fund distributions and taxes

The fund earns dividends, interest, and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. The fund also realizes capital gains from its investments and distributes these gains (less any losses) as capital gain distributions. If you purchased your shares in the secondary market, your broker is responsible for distributing the income and capital gain distributions to you. The fund normally distributes any net investment income and any net realized capital gains annually.

For federal income tax purposes, distributions of net investment income are generally taxable to you as ordinary income. Taxes on distributions of capital gains are determined by how long the fund owned (or is deemed to have owned) the investments that generated them, rather than by how long you have owned (or are deemed to have owned) your shares. Distributions that the fund properly reports to you as gains from investments that the fund owned for more than one year are generally taxable to you as long-term capital gains includible in net capital gain and taxed to individuals at long-term capital tax rates. Distributions of gains from investments that the fund owned for one year or less and gains on the sale of or payment on bonds characterized as market discount are generally taxable to you as ordinary income. Distributions that the fund properly reports to you as “qualified dividend income” are taxable at the reduced rates applicable to your net capital gain provided that both you and the fund meet certain holding period and other requirements.

Distributions by the fund to retirement plans that qualify for tax-advantaged treatment under federal income tax laws will not be taxable. Special tax rules apply to investments through such plans. You should consult your tax advisor to determine the suitability of the fund as an investment through such a plan and the tax treatment of distributions (including distributions of amounts attributable to an investment in the fund) from such a plan.

Unless you are investing through a tax-advantaged retirement account (such as an IRA), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution because doing so may cost you money in taxes. Distributions are taxable to you even if they are paid from income or gains earned by the fund before your investment (and thus were included in the price you paid). Contact your financial representative to find out the distribution schedule for your fund.

The fund’s investments in foreign securities may be subject to foreign withholding or other taxes. In that case, the fund’s return on those investments would be decreased. If the fund meets certain requirements relating to its asset holdings, and the fund elects to pass through to its shareholders foreign tax credits or deductions, taxable shareholders will receive a deemed dividend in the amount of such foreign taxes and generally will be entitled to claim a credit or deduction with respect to these foreign taxes. Even if the fund elects to pass through to its shareholders foreign tax credits or deductions, tax-exempt shareholders and those who invest in the fund through tax-advantaged accounts such as IRAs will not benefit from any such tax credit or

26     Prospectus



 



deduction. Deemed dividends allocable to non-U.S. shareholders may be subject to U.S. withholding tax. In addition, the fund’s investments in foreign securities or foreign currencies may increase or accelerate the fund’s recognition of ordinary income and may affect the timing or amount of the fund’s distributions.

The fund’s use of derivatives, if any, may affect the amount, timing and character of distributions to shareholders and, therefore, may increase the amount of taxes payable by shareholders.

Other tax considerations

Unlike other ETFs, the securities exchanged for a creation unit will not correspond pro rata to the positions in the fund’s portfolio, and the fund will effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the fund may be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the fund had effected redemptions wholly on an in-kind basis. If investors buy shares when the fund has realized but not yet distributed income or capital gains, they will be “buying a dividend” by paying the full price for the shares and then receiving a portion of the price back in the form of a taxable distribution. Any taxable distributions investors receive will normally be taxable to them when they receive them.

Taxes on transactions

Purchases and sales of shares, as well as purchases and redemptions of creation units, may result in a capital gain or loss for federal tax purposes.

The above is a general summary of the tax implications of investing in the fund. Please refer to the SAI for further details. You should consult your tax advisor for more information on your own tax situation, including possible foreign, state and local taxes.
