PART I: INFORMATION ABOUT THE FUNDS

Part I of this Statement of Additional Information (the “SAI”) sets forth information about BlackRock LifePath^® Index Retirement Fund, BlackRock LifePath^® Index 2025 Fund, BlackRock LifePath^® Index 2030 Fund, BlackRock LifePath^® Index 2035 Fund, BlackRock LifePath^® Index 2040 Fund, BlackRock LifePath^® Index 2045 Fund, BlackRock LifePath^® Index 2050 Fund, BlackRock LifePath^® Index 2055 Fund, BlackRock LifePath^® Index 2060 Fund and BlackRock LifePath^® Index 2065 Fund (each, a “Fund” and collectively, the “Funds”), each a series of BlackRock Funds III (the “Trust”). It includes information about the Trust’s Board of Trustees (the “Board” or the “Board of Trustees”), the advisory and management services provided to and the management fees paid by the Funds, and information about other fees applicable to and services provided to the Funds. This Part I of this SAI should be read in conjunction with the Funds’ Prospectuses and those portions of Part II of this SAI that pertain to the Funds.

Please see the Funds’ Prospectuses for more information about each Fund’s investment objective and policies. Each Fund invests in a combination of equity and bond index funds and money market funds (the “Underlying Funds”) and may also invest in U.S. Government securities and short-term paper. BlackRock Fund Advisors (“BFA” or the “Manager”) serves as the investment adviser to the Funds. BlackRock Institutional Trust Company, N.A. (“BTC”) has granted the Trust a non-exclusive license to use the name “LifePath.” If the license agreement is terminated, the Trust, at BTC’s request, will cease using the “LifePath” name.

The investment objective and policies of a Fund determine the allocation of assets to the Underlying Funds, the degree of risk to which the Fund is subject and, ultimately, its performance. As with all investment companies, there can be no assurance that the investment objective of any Fund will be achieved.

In implementing each Fund’s investment strategy, from time to time, BFA, each Fund’s investment manager, may consider and employ techniques and strategies designed to minimize and defer the U.S. federal income taxes which may be incurred by shareholders in connection with their investment in such Fund.

Set forth below is a listing of some of the types of investments and investment strategies that a Fund and its Underlying Funds may use, and the risks and considerations associated with those investments and investment strategies. Please see Part II of this SAI for further information on these investments and investment strategies. Information contained in Part II about the risks and considerations associated with investments and/or investment strategies applies only to the extent a Fund makes each type of investment or uses each investment strategy. Information that does not apply to a Fund does not form a part of that Fund’s SAI and should not be relied on by investors in that Fund.

Only information that is clearly identified as applicable to a Fund is considered to form a part of that Fund’s SAI.

Regulation Regarding Derivatives. The Commodity Futures Trading Commission (“CFTC”) subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. To the extent a Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments.

The Funds may have investments in “underlying funds” (and such underlying funds themselves may invest in underlying funds) not advised by BFA (which for purposes of the no-action letter referenced below may include certain securitized vehicles, mortgage real estate investment trusts and/or investment companies that may invest in CFTC Derivatives), and therefore may be viewed by the CFTC as a commodity pool. BFA has no transparency into the holdings of these underlying funds because they are not advised by BFA. To address

I-10

this issue of lack of transparency, the CFTC staff issued a no-action letter on November 29, 2012 permitting the adviser of a fund that invests in such underlying funds and that would otherwise have filed a claim of exclusion pursuant to Rule 4.5 to delay registration as a “commodity pool operator” until six months from the date on which the CFTC issues additional guidance on the treatment of CFTC Derivatives held by underlying funds. BFA, the adviser of the Funds, has filed a claim with the CFTC for the Funds to rely on this no-action relief. Accordingly, BFA is not subject to registration or regulation as a “commodity pool operator” under the Commodity Exchange Act in respect of the Funds.

The Trust, on behalf of the Funds, has adopted restrictions and policies relating to investment of the Funds’ assets and their activities. Certain of the restrictions are fundamental policies of a Fund and may not be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities (which for this purpose and under the 1940 Act, means the lesser of (i) 67% of the shares represented at a meeting at which more than 50% of the outstanding shares are represented or (ii) more than 50% of the outstanding shares). The Trust, on behalf of the Funds, has also adopted certain non-fundamental investment restrictions, which may be changed by the Board without shareholder approval. None of the following fundamental or non-fundamental investment restrictions shall prevent a Fund from investing all of its assets in shares of another registered investment company with the same investment objective and fundamental policies (in a master/feeder structure).

The Funds are subject to the following investment restrictions, all of which are fundamental policies. Each Fund may not:

(1) Purchase the securities of issuers conducting their principal business activity in the same industry if, immediately after the purchase and as a result thereof, the value of a Fund’s investments in that industry would equal or exceed 25% of the current value of the Fund’s total assets, provided that this restriction does not limit a Fund’s: (i) investments in securities of other investment companies, (ii) investments in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, or (iii) investments in repurchase agreements collateralized by U.S. government securities;

(2) Purchase the securities of any single issuer if, as a result, with respect to 75% of a Fund’s total assets, more than 5% of the value of its total assets would be invested in the securities of such issuer or the Fund’s ownership would be more than 10% of the outstanding voting securities of such issuer, provided that this restriction does not limit a Fund’s cash or cash items, investments in securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities, or investments in securities of other investment companies;

(3) Borrow money or issue senior securities, except to the extent permitted under the 1940 Act, including the rules, regulations and any orders obtained thereunder;

(4) Make loans to other parties, except to the extent permitted under the 1940 Act, including the rules, regulations and any orders obtained thereunder. For the purposes of this limitation, entering into repurchase agreements, lending securities and acquiring any debt securities are not deemed to be the making of loans;

(5) Underwrite securities of other issuers, except to the extent that the purchase of permitted investments directly from the issuer thereof or from an underwriter for an issuer and the later disposition of such securities in accordance with a Fund’s investment program may be deemed to be an underwriting; and provided further, that the purchase by the Fund of securities issued by an open-end management investment company, or a series thereof, with substantially the same investment objective, policies and restrictions as the Fund shall not constitute an underwriting for purposes of this paragraph;

(6) Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from investing in securities or other instruments backed by real estate or securities of companies engaged in the real estate business); and

I-11

(7) Purchase or sell commodities, provided that (i) currency will not be deemed to be a commodity for purposes of this restriction, (ii) this restriction does not limit the purchase or sale of futures contracts, forward contracts or options, and (iii) this restriction does not limit the purchase or sale of securities or other instruments backed by commodities or the purchase or sale of commodities acquired as a result of ownership of securities or other instruments.

Notations Regarding the Funds’ Fundamental Investment Restrictions

The following notations are not considered to be part of the Funds’ fundamental investment restrictions and are subject to change without shareholder approval.

For purposes of investment restriction (1) above, with respect to a Fund’s industry classifications, each Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to each Fund as to how to classify issuers within or among industries.

With respect to paragraph (3) above, the 1940 Act currently allows a Fund to borrow up to one-third of the value of its total assets (including the amount borrowed) valued at the lesser of cost or market, less liabilities (not including the amount borrowed) at the time the borrowing is made. In addition, the Funds have received an exemptive order from the SEC permitting them to borrow through the Interfund Lending Program (discussed below), subject to the conditions of the exemptive order. With respect to paragraph (4) above, the 1940 Act and regulatory interpretations currently limit the percentage of a Fund’s securities that may be loaned to one-third of the value of its total assets.

Under its non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, each Fund may not:

1. Purchase securities of other investment companies, except to the extent permitted by the 1940 Act. As a matter of policy, however, each Fund will not purchase shares of any registered open-end investment company or registered unit investment trust, in reliance on Section 12(d)(1)(F) or (G) (the “fund of funds” provisions) of the 1940 Act, at any time a Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraph (G) of Section 12(d)(1).

2. Make short sales of securities or maintain a short position, except to the extent permitted by each Fund’s Prospectus and Statement of Additional Information, as amended from time to time, and applicable law.

Notwithstanding any other investment policy or restriction (whether or not fundamental), the Underlying Funds in which the Funds may invest have adopted certain investment restrictions that may be different from those listed above, thereby permitting the Funds to engage indirectly in investment strategies that are prohibited under the restrictions listed above. The investment restrictions of each Underlying Fund are set forth in its respective statement of additional information.

The Board consists of twelve individuals (each, a “Trustee”), ten of whom are not “interested persons” of the Trust as defined in the 1940 Act (the “Independent Trustees”). The registered investment companies advised by the Manager or its affiliates (the “BlackRock-advised Funds”) are organized into the BlackRock Multi-Asset Complex, the BlackRock Fixed-Income Complex, and the iShares Complex (each, a “BlackRock Fund Complex”). The Trust is included in the BlackRock Fund Complex referred to as the BlackRock Multi-Asset Complex. The Trustees also oversee as board members the operations of the other open-end registered investment companies included in the BlackRock Multi-Asset Complex.

The Board has overall responsibility for the oversight of the Trust and each Fund. The Chair of the Board is an Independent Trustee, and the Chair of each Board committee (each, a “Committee”) is an Independent Trustee. The Board has five standing Committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Ad Hoc Topics Committee. The role of the Chair of the Board is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys and other Trustees generally between meetings. The Chair of each

I-12

Committee performs a similar role with respect to the Committee. The Chair of the Board or the Chair of a Committee may also perform such other functions as may be delegated by the Board or the Committee from time to time. The Independent Trustees meet regularly outside the presence of Fund management, in executive session or with other service providers to each Fund. The Board has regular meetings five times a year, and may hold special meetings if required before its next regular meeting. Each Committee meets regularly to conduct the oversight functions delegated to that Committee by the Board and reports its findings to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and to allocate areas of responsibility among Committees and the full Board to enhance effective oversight.

The Board has engaged the Manager to manage each Fund on a day-to-day basis. The Board is responsible for overseeing the Manager, other service providers, the operations of each Fund and associated risks in accordance with the provisions of the 1940 Act, state law, other applicable laws, the Trust’s charter, and each Fund’s investment objective and strategies. The Board reviews, on an ongoing basis, each Fund’s performance, operations and investment strategies and techniques. The Board also conducts reviews of the Manager and its role in running the operations of each Fund.

Day-to-day risk management with respect to each Fund is the responsibility of the Manager or of sub-advisers or other service providers (depending on the nature of the risk), subject to the supervision of the Manager. Each Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by the Manager and the sub-advisers or other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Funds. Risk oversight forms part of the Board’s general oversight of each Fund and is addressed as part of various Board and Committee activities. The Board, directly or through a Committee, also reviews reports from, among others, management, the independent registered public accounting firm for each Fund, sub-advisers and internal auditors for the investment adviser or its affiliates, as appropriate, regarding risks faced by each Fund and management’s or the service provider’s risk functions. The Committee system facilitates the timely and efficient consideration of matters by the Trustees, and facilitates effective oversight of compliance with legal and regulatory requirements and of each Fund’s activities and associated risks. The Board has appointed a Chief Compliance Officer, who oversees the implementation and testing of the Trust’s compliance program and reports to the Board regarding compliance matters for the Funds and their service providers. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Audit Committee. The members of the Audit Committee (the “Audit Committee”) are Henry R. Keizer (Chair), Neil A. Cotty, Lena G. Goldberg and Kenneth L. Urish, all of whom are Independent Trustees. The principal responsibilities of the Audit Committee are to approve, and recommend to the full Board for approval, the selection, retention, termination and compensation of each Fund’s independent registered public accounting firm (the “Independent Registered Public Accounting Firm”) and to oversee the Independent Registered Public Accounting Firm’s work. The Audit Committee’s responsibilities include, without limitation, to (1) evaluate the qualifications and independence of the Independent Registered Public Accounting Firm; (2) approve all audit engagement terms and fees for each Fund; (3) review the conduct and results of each independent audit of each Fund’s annual financial statements; (4) review any issues raised by the Independent Registered Public Accounting Firm or Fund management regarding the accounting or financial reporting policies and practices of each Fund and the internal controls of each Fund and certain service providers; (5) oversee the performance of each Fund’s Independent Registered Public Accounting Firm; (6) review and discuss with management and each Fund’s Independent Registered Public Accounting Firm the performance and findings of each Fund’s internal auditors; (7) discuss with Fund management its policies regarding risk assessment and risk management as such matters relate to each Fund’s financial reporting and controls; (8) resolve any disagreements between Fund management and the Independent Registered Public Accounting Firm regarding financial reporting; and (9) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Audit Committee. The Board has adopted a written charter for the Audit Committee. During the fiscal year ended December 31, 2023, the Audit Committee met four times.

I-13

Governance and Nominating Committee. The members of the Governance and Nominating Committee (the “Governance Committee”) are Cynthia A. Montgomery (Chair), Susan J. Carter, Collette Chilton and Henry R. Keizer, all of whom are Independent Trustees. The principal responsibilities of the Governance Committee are to (1) identify individuals qualified to serve as Independent Trustees of the Trust and recommend Independent Trustee nominees for election by shareholders or appointment by the Board; (2) advise the Board with respect to Board composition, procedures and committees (other than the Audit Committee); (3) oversee periodic self-assessments of the Board and committees of the Board (other than the Audit Committee); (4) review and make recommendations regarding Independent Trustee compensation; (5) monitor corporate governance matters and develop appropriate recommendations to the Board; (6) act as the administrative committee with respect to Board policies and procedures, committee policies and procedures (other than the Audit Committee) and codes of ethics as they relate to Independent Trustees; and (7) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Governance Committee. The Governance Committee may consider nominations for Trustees made by each Fund’s shareholders as it deems appropriate. Fund shareholders who wish to recommend a nominee should send nominations to the Secretary of the Trust that include biographical information and set forth the qualifications of the proposed nominee. The Board has adopted a written charter for the Governance Committee. During the fiscal year ended December 31, 2023, the Governance Committee met nine times.

Compliance Committee. The members of the Compliance Committee (the “Compliance Committee”) are Lena G. Goldberg (Chair), Cynthia A. Montgomery, Donald C. Opatrny, Kenneth L. Urish and Claire A. Walton, all of whom are Independent Trustees. The Compliance Committee’s purpose is to assist the Board in fulfilling its responsibility to oversee regulatory and fiduciary compliance matters involving the Trust, the fund-related activities of BFA and any sub-adviser and the Trust’s third-party service providers. The Compliance Committee’s responsibilities include, without limitation, to (1) oversee the compliance policies and procedures of the Trust and its service providers and recommend changes or additions to such policies and procedures; (2) review information on and, where appropriate, recommend policies concerning the Trust’s compliance with applicable law; (3) review reports from, oversee the annual performance review of, and make certain recommendations and determinations regarding the Trust’s Chief Compliance Officer (the “CCO”), including determining the amount and structure of the CCO’s compensation and recommending such amount and structure to the full Board for approval and ratification; and (4) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Compliance Committee. The Board has adopted a written charter for the Compliance Committee. During the fiscal year ended December 31, 2023, the Compliance Committee met four times.

Performance Oversight Committee. The members of the Performance Oversight Committee (the “Performance Oversight Committee”) are Donald C. Opatrny (Chair), Susan J. Carter, Collette Chilton, Neil A. Cotty and Claire A. Walton, all of whom are Independent Trustees. The Performance Oversight Committee’s purpose is to assist the Board in fulfilling its responsibility to oversee each Fund’s investment performance relative to its agreed-upon performance objectives and to assist the Independent Trustees in their consideration of investment advisory agreements. The Performance Oversight Committee’s responsibilities include, without limitation, to (1) review information on, and make recommendations to the full Board in respect of, each Fund’s investment objective, policies and practices; (2) review information on each Fund’s investment performance; (3) review information on appropriate benchmarks and competitive universes and unusual or exceptional investment matters; (4) review personnel and other resources devoted to management of each Fund and evaluate the nature and quality of information furnished to the Performance Oversight Committee; (5) recommend any required action regarding changes in fundamental and non-fundamental investment policies and restrictions, fund mergers or liquidations; (6) request and review information on the nature, extent and quality of services provided to the shareholders; (7) make recommendations to the Board concerning the approval or renewal of investment advisory agreements; and (8) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Performance Oversight Committee. The Board has adopted a written charter for the Performance Oversight Committee. During the fiscal year ended December 31, 2023, the Performance Oversight Committee met four times.

I-14

Ad Hoc Topics Committee. The members of the Ad Hoc Topics Committee (the “Ad Hoc Topics Committee”) are Mark Stalnecker (Chair) and Lena G. Goldberg, both of whom are Independent Trustees, and John M. Perlowski, who serves as an interested Trustee. The principal responsibilities of the Ad Hoc Topics Committee are to (1) act on routine matters between meetings of the Board; (2) act on such matters as may require urgent action between meetings of the Board; and (3) exercise such other authority as may from time to time be delegated to the Ad Hoc Topics Committee by the Board. The Board has adopted a written charter for the Ad Hoc Topics Committee. During the fiscal year ended December 31, 2023, the Ad Hoc Topics Committee did not meet.

The Governance Committee has adopted a statement of policy that describes the experience, qualifications, skills and attributes that are necessary and desirable for potential Independent Trustee candidates (the “Statement of Policy”). The Board believes that each Independent Trustee satisfied, at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. Furthermore, in determining that a particular Independent Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Independent Trustees have balanced and diverse experience, skills, attributes and qualifications, which allow the Board to operate effectively in governing the Trust and protecting the interests of shareholders. Among the attributes common to all Independent Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with each Fund’s investment adviser, sub-advisers, other service providers, counsel and the Independent Registered Public Accounting Firm, and to exercise effective business judgment in the performance of their duties as Trustees.

Each Trustee’s ability to perform his or her duties effectively is evidenced by his or her educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Trust and the other funds in the BlackRock Fund Complexes (and any predecessor funds), other investment funds, public companies, non-profit entities or other organizations; ongoing commitment to and participation in Board and Committee meetings, as well as his or her leadership of standing and ad hoc committees throughout the years; or other relevant life experiences.

The table below discusses some of the experiences, qualifications and skills of each of the Trustees that support the conclusion that each Trustee should serve on the Board.

Each Trustee who is an Independent Trustee is paid as compensation an annual retainer of $335,000 per year for his or her services as a board member of the BlackRock-advised Funds in the BlackRock Multi-Asset Complex, including the Trust, and a $20,000 board meeting fee to be paid for each in-person board meeting attended (and may receive a board meeting fee for telephonic attendance at board meetings), for up to five board meetings held in a calendar year (compensation for meetings in excess of this number to be determined on a case-by-case basis), together with out-of-pocket expenses in accordance with a board policy on travel and other business expenses relating to attendance at meetings. The Chairs of the Audit Committee, Compliance Committee, Governance Committee and Performance Committee are paid as compensation an additional annual retainer of $45,000, respectively. The Chair of the Boards is paid an additional annual retainer of $150,000.

I-21

Investment Adviser

BFA provides investment advisory services to each Fund pursuant to an investment advisory contract (the “Advisory Contract”) with the Trust. Pursuant to the Advisory Contract, BFA furnishes to the Board periodic reports on the investment strategy and performance of each Fund.

BFA is an indirect wholly-owned subsidiary of BlackRock, Inc.

The Advisory Contract is subject to annual approval by (i) the Board or (ii) vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of a Fund, provided that in either event the continuance also is approved by a majority of Independent Trustees of the Trust, by a vote cast in person at a meeting called for the purpose of voting on such approval. The Advisory Contract is terminable without penalty on 60 days’ written notice by either party. The Advisory Contract will terminate automatically, as to each Fund, in the event of its assignment (as defined in the 1940 Act).

BFA is entitled to receive monthly fees at the annual rate of 0.05% of the average daily net assets of each Fund.

BlackRock Advisors, LLC (“BAL”) and BFA have contractually agreed to reimburse the Fund for Acquired Fund Fees and Expenses up to a maximum amount equal to the combined Management Fee and Administration Fee of each share class of the Fund, through June 30, 2025. In addition, BFA has contractually agreed to waive its management fees by the amount of investment advisory fees the Fund pays to BFA indirectly through its investment in money market funds managed by BFA or its affiliates, through June 30, 2025. The contractual agreements may be terminated upon 90 days’ notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund.

The fees and expenses of the Independent Trustees, counsel to the Independent Trustees and the independent registered public accounting firm that provides audit services in connection with the Funds (collectively

I-22

referred to as the “Independent Expenses”) are paid directly by the Funds. Each of BAL and BFA has contractually undertaken, through June 30, 2034, to reimburse or provide an offsetting credit to each Fund for such Independent Expenses.

For the past three fiscal years, each Fund paid BFA management fees, and BFA waived management fees and/or reimbursed expenses, as follows:
