Notes to the fund's portfolio
	Unless noted otherwise, the notes to the fund's portfolio are for the close of the fund's reporting period, which ran from January 1, 2024 through June 30, 2024 (the reporting period). Within the following notes to the portfolio, references to "Putnam Management" represent Putnam Investment Management, LLC, the fund's manager, an indirect wholly-owned subsidiary of Franklin Resources, Inc., and references to "ASC 820" represent Accounting Standards Codification 820 Fair Value Measurements and Disclosures.
*	Percentages indicated are based on net assets of $80,095,044.
	The dates shown on debt obligations are the original maturity dates.

ASC 820 establishes a three-level hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of the fund's investments. The three levels are defined as follows:

Level 1: Valuations based on quoted prices for identical securities in active markets.

Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3: Valuations based on inputs that are unobservable and significant to the fair value measurement.

The following is a summary of the inputs used to value the fund's net assets as of the close of the reporting period:

Putnam VT Government Money Market Fund (the fund) is a diversified series of Putnam Variable Trust (the Trust), a Massachusetts business trust registered under the 1940 Act as an open-end management investment company. The goal of the fund is to seek as high a rate of current income as Putnam Management believes is consistent with preservation of capital and maintenance of liquidity. The fund invests at least 99.5 percent of the fund's total assets in cash, U.S. government securities and repurchase agreements that are fully collateralized by U.S. government securities or cash. The fund invests mainly in debt securities that are obligations of the U.S. government, its agencies and instrumentalities and accordingly are backed by the full faith and credit of the United States (e.g., U.S. Treasury bills) or by the credit of a federal agency or government-sponsored entity (e.g., securities issued by Fannie Mae and Freddie Mac). The U.S. government securities in which the fund invests may also include variable and floating rate instruments and when-issued and delayed delivery securities (i.e., payment or delivery of the securities occurs at a future date for a predetermined price). Under normal circumstances, the fund invests at least 80% of the fund's net assets in U.S. government securities and repurchase agreements that are fully collateralized by U.S. government securities. This policy may be changed only after 60 days' notice to shareholders. The securities purchased by the fund are subject to quality, maturity, diversification and other requirements pursuant to rules promulgated by the SEC. Putnam Management may consider, among other factors, credit and interest rate risks and characteristics of the issuer or counterparty, as well as general market conditions, when deciding whether to buy or sell investments.

The fund offers class IA and class IB shares of beneficial interest. Class IA shares are offered at net asset value and are not subject to a distribution fee. Class IB shares are offered at net asset value and pay an ongoing distribution fee, which is identified in Note 2.

In the normal course of business, the fund enters into contracts that may include agreements to indemnify another party under given circumstances. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be, but have not yet been, made against the fund. However, the fund's management team expects the risk of material loss to be remote.

The fund has entered into contractual arrangements with an investment adviser, administrator, distributor, shareholder servicing agent and custodian, who each provide services to the fund. Unless expressly stated otherwise, shareholders are not parties to, or intended beneficiaries of these contractual arrangements, and these contractual arrangements are not intended to create any shareholder right to enforce them against the service providers or to seek any remedy under them against the service providers, either directly or on behalf of the fund.

Under the Trust's Agreement and Declaration of Trust, any claims asserted by a shareholder against or on behalf of the Trust (or its series), including claims against Trustees and Officers, must be brought in courts located within the Commonwealth of Massachusetts.

Note 1: Significant accounting policies

The fund follows the accounting and reporting guidance in Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946) and applies the specialized accounting and reporting guidance in U.S. Generally Accepted Accounting Principles (U.S. GAAP), including, but not limited to, ASC 946. The following is a summary of significant accounting policies consistently followed by the fund in the preparation of its financial statements. The preparation of financial statements is in conformity with accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations. Actual results could differ from those estimates. Subsequent events after the Statement of assets and liabilities date through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.

Investment income, realized gains and losses and expenses of the fund are borne pro-rata based on the relative net assets of each class to the total net assets of the fund, except that each class bears expenses unique to that class (including the distribution fees applicable to such classes). Each class votes as a class only with respect to its own distribution plan or other matters on which a class vote is required by law or determined by the Trustees. Shares of each class would receive their pro-rata share of the net assets of the fund, if the fund were liquidated. In addition, the Trustees declare separate dividends on each class of shares.

Security valuation Portfolio securities and other investments are valued using policies and procedures adopted by the Board of Trustees (Trustees). The Trustees have formed a Pricing Committee to oversee the implementation of these procedures. Under compliance policies and procedures approved by the Trustees, the Trustees have designated the fund's investment manager as the valuation designee and has responsibility for oversight of valuation. The investment manager is assisted by the fund's administrator in performing this responsibility, including leading the cross-functional Valuation Committee (VC). The VC is responsible for making fair value determinations, evaluating the effectiveness of the pricing policies of the fund and reporting to the Trustees.

The valuation of the fund's portfolio instruments is determined by means of the amortized cost method (which approximates fair value) as set forth in Rule 2a-7 under the 1940 Act. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity and is generally categorized as a Level 2 security.

Joint trading account Pursuant to an exemptive order from the SEC, the fund may transfer uninvested cash balances into a joint trading account along with the cash of other registered investment companies and certain other accounts managed by Putnam Management. These balances may be invested in issues of short-term investments having maturities of up to 90 days.

Repurchase agreements The fund, or any joint trading account, through its custodian, receives delivery of the underlying securities, the fair value of which at the time of purchase is required to be in an amount at least equal to the resale price, including accrued interest. Collateral for certain tri-party repurchase agreements, which totaled $70,626,091 at the end of the reporting period, is held at the counterparty's custodian in a segregated account for the benefit of the fund and the counterparty. Putnam Management is responsible for determining that the value of these underlying securities is at all times at least equal to the resale price, including accrued interest. In the event of default or bankruptcy by the other party to the agreement, retention of the collateral may be subject to legal proceedings.

Security transactions and related investment income Security transactions are recorded on the trade date (the date the order to buy or sell is executed). Interest income, including amortization and accretion of premiums and discounts, is recorded on the accrual basis. Gains or losses on securities sold are determined on the identified cost basis.

Interfund lending The fund, along with other Putnam funds, may participate in an interfund lending program pursuant to an exemptive order issued by the SEC. This program allows the fund to lend to other Putnam funds that permit such transactions. Interfund lending transactions are subject to each fund's investment policies and borrowing and lending limits. Interest earned or paid on the interfund lending transaction will be based on the average of certain current market rates. During the reporting period, the fund did not utilize the program.

Lines of credit The fund participates, along with other Putnam funds, in a $320 million syndicated unsecured committed line of credit, provided by State Street ($160 million) and JPMorgan ($160 million), and a $235.5 million unsecured uncommitted line of credit, provided by State Street. Borrowings may be made for temporary or emergency purposes, including the funding of shareholder

6 Putnam VT Government Money Market Fund

redemption requests and trade settlements. Interest is charged to the fund based on the fund's borrowing at a rate equal to 1.25% plus the higher of (1) the Federal Funds rate and (2) the Overnight Bank Funding Rate for the committed line of credit and 1.30% plus the higher of (1) the Federal Funds rate and (2) the Overnight Bank Funding Rate for the uncommitted line of credit. A closing fee equal to 0.04% of the committed line of credit and 0.04% of the uncommitted line of credit has been paid by the participating funds and a $75,000 fee has been paid by the participating funds to State Street as agent of the syndicated committed line of credit. In addition, a commitment fee of 0.21% per annum on any unutilized portion of the committed line of credit is allocated to the participating funds based on their relative net assets and paid quarterly. During the reporting period, the fund had no borrowings against these arrangements.

Federal taxes It is the policy of the fund to distribute all of its taxable income within the prescribed time period and otherwise comply with the provisions of the Internal Revenue Code of 1986, as amended (the Code), applicable to regulated investment companies.

The fund is subject to the provisions of Accounting Standards Codification 740 Income Taxes (ASC 740). ASC 740 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The fund did not have a liability to record for any unrecognized tax benefits in the accompanying financial statements. No provision has been made for federal taxes on income, capital gains or unrealized appreciation on securities held nor for excise tax on income and capital gains. Each of the fund's federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

The aggregate identified cost on a financial reporting and tax basis is the same.

Distributions to shareholders Income dividends are recorded daily by the fund and are paid monthly. Distributions from capital gains, if any, are paid at least annually. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund's fiscal year. Reclassifications are made to the fund's capital accounts to reflect income and gains available for distribution (or available capital loss carryovers) under income tax regulations.

Expenses of the Trust Expenses directly charged or attributable to any fund will be paid from the assets of that fund. Generally, expenses of the Trust will be allocated among and charged to the assets of each fund on a basis that the Trustees deem fair and equitable, which may be based on the relative assets of each fund or the nature of the services performed and relative applicability to each fund.

Beneficial interest At the close of the reporting period, insurance companies or their separate accounts were record owners of all but a de minimis number of the shares of the fund. Approximately 32.7% of the fund is owned by accounts of one insurance company.

Note 2: Management fee, administrative services and other transactions

The fund pays Putnam Management a management fee (based on the fund's average net assets and computed and paid monthly) at annual rates that may vary based on the average of the aggregate net assets of all open-end mutual funds sponsored by Putnam Management (excluding net assets of funds that are invested in, or that are invested in by, other Putnam funds to the extent necessary to avoid "double counting" of those assets). Such annual rates may vary as follows:

0.440%	of the first $5 billion,
0.390%	of the next $5 billion,
0.340%	of the next $10 billion,
0.290%	of the next $10 billion,
0.240%	of the next $50 billion,
0.220%	of the next $50 billion,
0.210%	of the next $100 billion and
0.205%	of any excess thereafter.

For the reporting period, the management fee represented an effective rate (excluding the impact from any expense waivers in effect) of 0.135% of the fund's average net assets.

Effective July 15, 2024, Putnam Management transferred its management contract with the fund to Franklin Advisers. As a result of the transfer, Franklin Advisers replaced Putnam Management as the investment adviser of the fund. In addition, effective July 15, 2024, Franklin Advisers has retained Putnam Management as a sub-adviser for the fund pursuant to a new sub-advisory agreement between Franklin Advisers and Putnam Management.

Putnam Management has contractually agreed, through April 30, 2026, to waive fees and/or reimburse the fund's expenses to the extent necessary to limit the cumulative expenses of the fund, exclusive of brokerage, interest, taxes, investment-related expenses, extraordinary expenses, acquired fund fees and expenses and payments under the fund's investor servicing contract, investment management contract and distribution plan, on a fiscal year-to-date basis to an annual rate of 0.20% of the fund's average net assets over such fiscal year-to-date period. During the reporting period, the fund's expenses were not reduced as a result of this limit.

Putnam Management may from time to time voluntarily undertake to waive fees and/or reimburse certain fund expenses in order to enhance the annualized net yield for the fund. Any such waiver or reimbursement would be voluntary and may be modified or discontinued by Putnam Management at any time without notice. For the reporting period, Putnam Management did not waive any specific distribution fees from the fund.

PIL is authorized by the Trustees to manage a separate portion of the assets of the fund as determined by Putnam Management from time to time. PIL did not manage any portion of the assets of the fund during the reporting period. If Putnam Management were to engage the services of PIL, Putnam Management would pay a quarterly sub-management fee to PIL for its services at an annual rate of 0.20% of the average net assets of the portion of the fund managed by PIL. Effective July 15, 2024, Putnam Management transferred its sub-management contract with PIL in respect of the fund to Franklin Advisers.

Effective June 1, 2024, under an agreement with Putnam Management, Franklin Templeton Services provides certain administrative services to the fund. The fee for those services is paid by Putnam Management based on the fund's average daily net assets and is not an additional expense of the fund.

The fund reimburses Putnam Management an allocated amount for the compensation and related expenses of certain officers of the fund and their staff who provide administrative services to the fund. The aggregate amount of all such reimbursements is determined annually by the Trustees.

Custodial functions for the fund's assets are provided by State Street. Custody fees are based on the fund's asset level, the number of its security holdings and transaction volumes.

Putnam Investor Services, Inc., an affiliate of Putnam Management, provides investor servicing agent functions to the fund. Putnam Investor Services, Inc. was paid a monthly fee for investor servicing at an annual rate of 0.07% of the fund's average daily net assets. During the reporting period, the expenses for each class of shares related to investor servicing fees were as follows:

Class IA	$14,569
Class IB	12,933
Total	$27,502

The fund has entered into expense offset arrangements with Putnam Investor Services, Inc. and State Street whereby Putnam Investor Services, Inc.'s and State Street's fees are reduced by credits allowed on cash balances. For the reporting period, the fund's expenses were reduced by $502 under the expense offset arrangements.

Each Independent Trustee of the fund receives an annual Trustee fee, of which $60, as a quarterly retainer, has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees also are reimbursed for expenses they incur relating to their services as Trustees.

The fund has adopted a Trustee Fee Deferral Plan (the Deferral Plan) which allows the Trustees to defer the receipt of all or a portion of Trustees fees payable from July 1, 1995 through December 31, 2023. The deferred fees remain invested in certain Putnam funds until distribution in accordance with the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension plan (the Pension Plan) covering all Trustees of the fund who have served as a Trustee for at least five years and were first elected prior to 2004. Benefits under the Pension Plan are equal to 50% of the Trustee's average annual attendance and retainer fees for the three years ended December 31, 2005. The retirement benefit is payable during a Trustee's lifetime, beginning the year following retirement, for the number of years of service through December 31, 2006. Pension expense for the fund is included in Trustee compensation and expenses in the Statement of operations. Accrued pension liability is included in Payable for Trustee compensation and expenses in the Statement of assets and liabilities. The Trustees have terminated the Pension Plan with respect to any Trustee first elected after 2003.

Putnam VT Government Money Market Fund 7

The fund has adopted a distribution plan (the Plan) with respect to its class IB shares pursuant to Rule 12b-1 under the 1940 Act. The purpose of the Plan is to compensate Putnam Retail Management Limited Partnership, an indirect wholly-owned subsidiary of Franklin Templeton, for services provided and expenses incurred in distributing shares of the fund. Effective August 2, 2024, Franklin Distributors ,LLC, an indirect wholly-owned subsidiary of Franklin Templeton, will replace Putnam Retail Management Limited Partnership as the fund's distributor and principal underwriter. The Plan provides for payment by the fund to Putnam Retail Management Limited Partnership at an annual rate of up to 0.35% of the average net assets attributable to the fund's class IB shares. The Trustees have approved payment by the fund at an annual rate of 0.25% of the average net assets attributable to the fund's class IB shares. The expenses related to distribution fees during the reporting period are included in Distribution fees in the Statement of operations.

Note 3: Purchases and sales of securities

During the reporting period, the cost of purchases and the proceeds from sales (including maturities) of investment securities (all short-term obligations) aggregated $8,415,799,458 and $8,415,046,000, respectively. The fund may purchase or sell investments from or to other Putnam funds in the ordinary course of business, which can reduce the fund's transaction costs, at prices determined in accordance with SEC requirements and policies approved by the Trustees. During the reporting period, purchases or sales from or to other Putnam funds, if any, did not represent more than 5% of the fund's total cost of purchases and/or total proceeds from sales.

Note 4: Capital shares

At the close of the reporting period, there were an unlimited number of shares of beneficial interest authorized. Subscriptions and redemptions are presented at the omnibus level. Transactions in capital shares were as follows:

Putnam VT Government Money Market Fund 9

Board approval of management and subadvisory agreements (Unaudited)

At its meeting on June 28, 2024, the Board of Trustees of your fund, including all of the Trustees who are not "interested persons" (as this term is defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of the Putnam mutual funds, closed-end funds and exchange-traded funds (collectively, the "funds") (the "Independent Trustees"), approved a New Management Contract (defined below) between your fund and Franklin Advisers, Inc. ("Franklin Advisers"), a new Sub-Management Contract (defined below) for your fund between Franklin Advisers and its affiliate, Putnam Investments Limited ("PIL"), and a new subadvisory agreement (the "New Subadvisory Agreement") for your fund between Franklin Advisers and Putnam Investment Management, LLC ("Putnam Management") (collectively, the "New Advisory Contracts"). Franklin Advisers, Putnam Management, and PIL are each indirect, wholly owned subsidiaries of Franklin Resources, Inc. ("Franklin Templeton").

The Trustees considered the proposed New Advisory Contracts in connection with an internal reorganization (the "Reorganization") whereby the fixed income and Investment Solutions investment operations of Putnam Management, your fund's investment adviser prior to the Reorganization, were combined with those of Franklin Advisers. As part of the Reorganization, Franklin Advisers assumed the role of investment adviser for your fund and the other Putnam fixed income and Investment Solutions mutual funds, exchange-traded funds and closed-end funds (collectively, the "FI/IS Funds"), which was accomplished through a transfer by Putnam Management of all of its rights and obligations under the previous management contracts between Putnam Management and the FI/IS Funds (the "Previous Management Contracts") and the previous sub-management contract between Putnam Management and its affiliate, PIL, with respect to the FI/IS Funds (the "Previous Sub-Management Contract," and, together with the Previous Management Contracts, the "Previous Contracts") to Franklin Advisers (the "Contract Transfers") by means of assignment and assumption agreements (the Previous Management Contracts and the Previous Sub-Management Contract, as modified by the terms of the related assignment and assumption agreements, are hereinafter referred to as the "New Management Contracts" and the "New Sub-Management Contract," respectively). (Because PIL is an affiliate of Franklin Advisers and Franklin Advisers remains fully responsible for all services provided by PIL, the Trustees did not attempt to evaluate PIL as a separate entity.)

In addition to the New Management Contracts and New Sub-Management Contract, the Board of Trustees of your fund considered and approved the New Subadvisory Agreement pursuant to which Franklin Advisers retained Putnam Management as sub-adviser for each FI/IS Fund so that, following the Reorganization, Putnam Management's equity team, which was not part of the Reorganization, could continue to provide certain services that it had historically provided to the FI/IS Funds, including, as applicable, the management of the equity portion of a FI/IS Fund's portfolio, including equity trade execution services, the provision of derivatives and other investment trading facilities for a transitional period, and the provision of proxy voting services for a transitional period (the "Services").

In connection with the review process, the Independent Trustees' independent legal counsel (as that term is defined in Rule 0-1(a)(6)(i) under the 1940 Act) met with representatives of Putnam Management and Franklin Templeton to discuss the contract review materials that would be furnished to the Contract Committee. The Board of Trustees, with the assistance of its Contract Committee (which consists solely of Independent Trustees) and its independent legal counsel, requested and evaluated all information it deemed reasonably necessary under the circumstances in connection with its review of the New Management Contracts. Over the course of several months ending in June 2024, the Contract Committee met on a number of occasions with representatives of Putnam Management and Franklin Templeton, and separately in executive session, to consider the information provided. Throughout this process, the Contract Committee was assisted by the members of the Board of Trustees' independent staff and by independent legal counsel for the Independent Trustees.

At the Board of Trustees' June 2024 meeting, the Contract Committee met in executive session to discuss and consider its recommendations with respect to the approval of the New Advisory Contracts. At that meeting, the Contract Committee also met in executive session with the other Independent Trustees to discuss its observations and recommendations.

The Trustees noted that Franklin Templeton viewed the Reorganization as a further step in the integration of the legacy Putnam Management and Franklin Advisers fixed income and Investment Solutions organizations, offering potential operational efficiencies and enhanced investment resources for the FI/IS Funds. The Trustees also considered, among other factors, that:

• The Contract Transfers would not result in a change in the senior management at Franklin Templeton, so that the same management will be in place before and after the Contract Transfers, which contemplate no reduction in the nature and level of the advisory and administrative services provided to the FI/IS Funds;

• The portfolio managers who are responsible for the day-to-day management of the FI/IS Funds would be the same immediately prior to, and immediately after, the Contract Transfers, and these investment personnel would have access to the same research and other resources to support their respective investment management functions both before and immediately after the Contract Transfers; and

• The Contract Transfers would not result in an increase in the advisory fee rates payable by each FI/IS Fund and that, other than an acknowledgment by Franklin Advisers and Putnam Management that for purposes of the New Management Contracts, each applicable FI/IS Fund will continue to be "an open-end fund sponsored by Putnam Management," for purposes of calculating the advisory fee rates, and updating the parties to the agreements, the terms of the New Management Contracts and New Sub-Management Contract were substantially identical to those under the Previous Contracts (including with respect to the term of the New Management Contracts and New Sub-Management Contract, which run through June 30, 2025, unless the contracts are sooner terminated or continued pursuant to their terms).

With respect to the New Subadvisory Agreement, the Trustees considered that, under the agreement, Putnam Management would provide any necessary Services to the applicable FI/IS Fund under generally the same terms and conditions related to the FI/IS Fund as such Services were previously provided by Putnam Management under the FI/IS Fund's Previous Management Contract. The Trustees also considered that Franklin Advisers would be responsible for overseeing the Services provided to the FI/IS Funds by Putnam Management under the New Subadvisory Agreement and would compensate Putnam Management for such services out of the fees it receives under the New Management Contracts. The Trustees further noted Franklin Advisers' and Putnam Management's representations that Putnam Management's

10 Putnam VT Government Money Market Fund

appointment as sub-adviser to the FI/IS Funds would not result in any material change in the nature or level of investment advisory services provided to the FI/IS Funds.

The Trustees also considered that, prior to the Reorganization, counsel to Franklin Advisers and Putnam Management had provided a legal opinion that the Contract Transfers would not result in an "assignment" under the 1940 Act of the Previous Contracts or a material amendment of those contracts, and, therefore, the New Management Contracts and New Sub-Management Contract did not require shareholder approval. In addition, the Trustees considered that counsel to Franklin Advisers and Putnam Management had provided a legal opinion that shareholder approval of the New Subadvisory Agreement was not required under the 1940 Act.

General conclusions

In addition to the above considerations, the Independent Trustees' approvals were based on the following conclusions:

• That the fee schedule in effect for your fund represented reasonable compensation in light of the nature and quality of the services being provided to the fund, the fees paid by competitive funds and the application of certain reductions and waivers noted below; and

• That the fee schedule in effect for your fund represented an appropriate sharing between fund shareholders and Franklin Advisers of any economies of scale as may exist in the management of the fund at current asset levels.

These conclusions were based on a comprehensive consideration of all information provided to the Trustees and were not the result of any single factor. Some of the factors that figured particularly in the Trustees' deliberations and how the Trustees considered these factors are described below, although individual Trustees may have evaluated the information presented differently, giving different weights to various factors. The considerations and conclusions discussed herein were also informed by the fact that there would be continuity in the management of the FI/IS Funds, including your fund, immediately following the Reorganization (i.e., the same portfolio managers that managed the fund prior to the Reorganization would be in place immediately following the Reorganization). The Trustees also considered that the FI/IS Funds had no operating history with Franklin Templeton or its affiliates prior to 2024.

Management fee schedules and total expenses

Under its Previous Management Contract and under its New Management Contract, your fund has the benefit of breakpoints in its management fee schedule that provide shareholders with reduced fee levels as assets under management in the Putnam family of funds increase ("Fund Family Breakpoints"). The Trustees considered that breakpoints in a fund's management fee schedule, such as the Fund Family Breakpoints in place for your fund, were one way in which economies of scale in managing a fund can be shared with the fund's shareholders. The Trustees reviewed the total expenses of each Putnam fund, recognizing that in most cases management fees represented the major, but not the sole, determinant of total costs to fund shareholders. (Two mutual funds and each of the exchange-traded funds have implemented so-called "all-in" or unitary management fees covering substantially all routine fund operating costs.)

As in the past, the Trustees also focused on the competitiveness of each fund's total expense ratio. The Trustees, Putnam Management and the funds' investor servicing agent, Putnam Investor Services, Inc. ("PSERV"), have implemented expense limitations. These expense limitations were: (i) a contractual expense limitation applicable to specified mutual funds, including your fund, of 25 basis points on investor servicing fees and expenses and (ii) a contractual expense limitation applicable to specified mutual funds, including your fund, of 20 basis points on so-called "other expenses" (i.e., all expenses exclusive of management fees, distribution fees, investor servicing fees, investment-related expenses, interest, taxes, brokerage commissions, acquired fund fees and expenses and extraordinary expenses). These expense limitations attempt to maintain competitive expense levels for the funds. Most funds, including your fund, had sufficiently low expenses that these expense limitations were not operative during their fiscal years ending in 2023. Franklin Advisers, who now serves as your fund's investment adviser following the Reorganization, and PSERV have agreed to maintain these expense limitations until at least April 30, 2026. Franklin Advisers' and PSERV's commitment to these expense limitation arrangements, which were intended to support an effort to have fund expenses meet competitive standards, was an important factor in the Trustees' decision to approve your fund's New Advisory Contracts.

The Trustees reviewed comparative fee and expense information for a custom group of competitive funds selected by Broadridge Financial Solutions, Inc. ("Broadridge"). This comparative information included your fund's percentile ranking for effective management fees and total expenses (excluding any applicable 12b-1 fees), which provides a general indication of your fund's relative standing. In the custom peer group, your fund ranked in the first quintile in effective management fees (determined for your fund and the other funds in the custom peer group based on fund asset size and the applicable contractual management fee schedule) and in the fourth quintile in total expenses (excluding any applicable 12b-1 fees) as of December 31, 2023. The first quintile represents the least expensive funds and the fifth quintile the most expensive funds. The fee and expense data reported by Broadridge as of December 31, 2023 reflected the most recent fiscal year-end data available in Broadridge's database at that time.

In connection with their review of fund management fees and total expenses, the Trustees also reviewed the costs of the services provided and the profits realized by Putnam Management and its affiliates from their contractual relationships with the funds. This information included year-over-year data with respect to revenues, expenses and profitability of Putnam Management and its affiliates relating to the investment management, investor servicing and distribution services provided to the funds, as applicable. In this regard, the Trustees also reviewed an analysis of the revenues, expenses and profitability of Putnam Management and its affiliates, allocated on a fund-by-fund basis, with respect to (as applicable) the funds' management, distribution and investor servicing contracts. For each fund, the analysis presented information about revenues, expenses and profitability in 2023 for each of the applicable agreements separately and for the agreements taken together on a combined basis. The Trustees also reviewed the revenues, expenses and profitability of Franklin Templeton's global investment management business and its U.S. registered investment company business, which includes the financial results of Franklin Advisers. Because the FI/IS Funds had no operating history with Franklin Templeton or its affiliates, the Trustees did not review fund-by-fund profitability information for Franklin Templeton. The Trustees concluded that, at current asset levels, the fee schedules in place for each of the funds, including the fee schedule for your fund, represented reasonable compensation for the services to be provided by Franklin Advisers (which are substantially identical to those historically provided by Putnam Management) and represented an appropriate sharing between fund shareholders and Franklin Advisers of any economies of scale as may exist in the management of the funds at that time.

Putnam VT Government Money Market Fund 11

The information examined by the Trustees in connection with their review of the New Advisory Contracts included information regarding services provided and fees charged by Putnam Management and its affiliates to other clients, including collective investment trusts offered in the defined contribution retirement plan market, sub-advised mutual funds, private funds sponsored by affiliates of Putnam Management, model-only separately managed accounts and Putnam Management's manager-traded separately managed account programs. This information included, in cases where a product's investment strategy corresponds with a FI/IS Fund's strategy, comparisons of those fees with fees charged to the funds, as well as an assessment of the differences in the services provided to these clients as compared to the services provided to the funds. The Trustees also considered information regarding services provided and fees charged by Franklin Advisers and its other Franklin Templeton affiliates to other clients, including U.S. registered mutual funds, funds organized outside of the United States (i.e., offshore funds), separate accounts (including separately managed accounts), collective investment trusts and sub-advised funds, which included, where applicable, the specific fees charged to strategies that are comparable to those of the FI/IS Funds. The Trustees observed that the differences in fee rates between these clients and the funds are by no means uniform when examined by individual asset sectors, suggesting that differences in the pricing of investment management services to these types of clients may reflect, among other things, historical competitive forces operating in separate marketplaces. The Trustees considered the fact that in many cases fee rates across different asset classes are higher on average for 1940 Act-registered funds than for other clients, and the Trustees also considered the differences between the services that Putnam Management historically provided and that Franklin Advisers will provide to the FI/IS Funds as investment adviser and those that they provide to their other clients. The Trustees did not rely on these comparisons to any significant extent in concluding that the management fees paid by your fund are reasonable.

Investment performance

The quality of the investment process provided by Putnam Management represented a major factor in the Trustees' evaluation of the quality of services provided by Putnam Management under your fund's Previous Management Contract and was also a significant factor in considering approval of your fund's New Management Contract, since the portfolio managers of your fund that were employed by Putnam Management prior to the Reorganization would continue to serve as portfolio managers of your fund immediately following the Reorganization as employees of Franklin Advisers. The Trustees were assisted in their review of Putnam Management's investment process and performance by the work of the investment oversight committees of the Trustees and the full Board of Trustees, which met on a regular basis with individual portfolio managers and with senior management of Putnam Management's Investment Division throughout the year. The Trustees concluded that Putnam Management generally provided a high-quality investment process - based on the experience and skills of the individuals assigned to the management of fund portfolios, the resources made available to them and in general Putnam Management's ability to attract and retain high-quality personnel - but also recognized that this does not guarantee favorable investment results for every fund in every time period. In addition to Putnam Management's investment process and performance, the Trustees considered aggregate performance information for Franklin Advisers' fixed income and Investment Solutions investment strategies, and also met with senior investment leadership at Franklin Advisers, including the respective heads of the fixed income and Investment Solutions teams and the Head of Public Market Investments.

The Trustees considered that, in the aggregate, peer-relative and benchmark-relative Putnam fund performance was generally strong in 2023 against a backdrop of largely solid fixed income markets and strong but volatile equity markets, which were characterized by a concentration of performance among large-cap growth stocks. The Trustees also noted that corporate earnings and employment figures continued to generally show strength, underpinning market rallies in 2023, while inflation concerns, Federal Reserve actions to reduce inflation and geopolitical tensions continued to be a focus of investors. For the one-year period ended December 31, 2023, the Trustees considered that the Putnam funds, on an asset-weighted basis, ranked in the 32nd percentile of their peers as determined by LSEG Lipper ("Lipper") and, on an asset-weighted-basis, outperformed their benchmarks by 2.8% gross of fees over the one-year period. The Committee also noted that the funds' aggregate performance over longer-term periods continued to be strong, with the funds, on an asset-weighted basis, ranking in the 31st, 21st, and 22nd percentiles of their Lipper peers over the three-year, five-year and ten-year periods ended December 31, 2023, respectively. The Trustees further noted that the funds, in the aggregate, outperformed their benchmarks on a gross basis for each of the three-year, five-year and ten-year periods. The Trustees also considered the Morningstar, Inc. ratings assigned to the funds, noting that 45 funds were rated four or five stars at the end of 2023, which represented an increase of 5 funds year-over-year. The Trustees also considered that 18 funds were five-star rated at the end of 2023, which was a year-over-year increase of 11 funds, and that 90% of the funds' aggregate assets were in four- or five-star rated funds at year end.

In addition to the performance of the individual Putnam funds, the Trustees considered, as they had in prior years, the performance of The Putnam Fund complex versus competitor fund complexes, as reported in the Barron's/Lipper Fund Families survey (the "Survey"). The Trustees noted that the Survey ranks mutual fund companies based on their performance across a variety of asset types, and that The Putnam Fund complex had performed exceptionally well in 2023. In this regard, the Trustees considered that The Putnam Fund complex had ranked 1st out of 49 fund companies, 1st out of 47 fund companies and 5th out of 46 fund companies for the one-year, five-year and ten-year periods, respectively. The Trustees also noted that 2023 had marked the seventh year in a row that The Putnam Fund complex had ranked in the top ten fund companies. They also noted, however, the disappointing investment performance of some Putnam funds for periods ended December 31, 2023 and considered information provided by Putnam Management regarding the factors contributing to the underperformance and, where relevant, actions being taken to improve the performance of these particular funds. The Trustees indicated their intention to continue to monitor the performance of those funds.

For purposes of the Trustees' evaluation of the Putnam funds' investment performance, the Trustees generally focus on a competitive industry ranking of each fund's total net return over a one-year, three-year and five-year period. For a number of Putnam funds with relatively unique investment mandates for which Putnam Management informed the Trustees that meaningful competitive performance rankings are not considered to be available, the Trustees evaluated performance based on their total gross and net returns and comparisons of those returns to the returns of selected investment benchmarks. In the case of your fund, the Trustees considered that its class IA share cumulative total return

12 Putnam VT Government Money Market Fund

performance at net asset value was in the following quartiles of its Lipper peer group (Lipper VP (Underlying Funds) - U.S. Government Money Market Funds) for the one-year, three-year and five-year periods ended December 31, 2023 (the first quartile representing the best-performing funds and the fourth quartile the worst-performing funds):

One-year period

Over the one-year, three-year and five-year periods ended December 31, 2023, there were 55, 54 and 52 funds, respectively, in your fund's Lipper peer group. (When considering performance information, shareholders should be mindful that past performance is not a guarantee of future results.)

Brokerage and soft-dollar allocations and other benefits; distribution

The Trustees considered various potential benefits that Franklin Advisers and Putnam Management may receive in connection with the services provided under the New Advisory Contracts your fund. These include benefits related to brokerage allocation and the use of soft dollars, whereby a portion of the commissions paid by a fund for brokerage may be used to acquire research services that are expected to be useful to Franklin Advisers and Putnam Management in managing the assets of the fund and of other clients. Subject to policies established by the Trustees, soft dollars generated by these means are used predominantly to acquire brokerage and research services (including third-party research and market data) that would enhance Franklin Advisers' and Putnam Management's investment capabilities and supplement their internal research efforts. The Trustees intend to continue to monitor regulatory and industry developments in this area with the assistance of their Brokerage Committee. In addition, with the assistance of their Brokerage Committee, the Trustees intend to continue to monitor the allocation of the funds' brokerage in order to ensure that the principle of seeking best price and execution remains paramount in the portfolio trading process. Your fund is not expected to generate a significant amount of soft-dollar credits.

The Trustees also considered other potential benefits that Franklin Advisers and Putnam Management may receive in connection with the services provided under the New Advisory Contracts your fund. These potential benefits included, among others, Franklin Advisers' and Putnam Management's registered fund businesses aiding in the growth of their non-registered fund businesses and the use of an affiliated transfer agent's services (in the case of your fund, PSERV, which is affiliated with Franklin Advisers and Putnam Management), where the fees for those services are paid by the fund.

Franklin Advisers may also receive benefits from payments made to Franklin Advisers' affiliates by the mutual funds for distribution services. In connection with the planned consolidation of Putnam Retail Management Limited Partnership ("PRM") with Franklin Distributors, LLC ("FD"), which is expected to take place in August 2024 (the "Consolidation"), the Trustees appointed FD as principal underwriter of the mutual funds, effective on or around the time of the Consolidation. Both PRM and FD are affiliates of Franklin Advisers and Putnam Management. In approving the continuation of your fund's distribution plans, the Trustees concluded that the fees payable by the mutual funds to PRM, prior to FD succeeding PRM as principal underwriter for the mutual funds, and to be paid to FD, once it assumes the role of principal underwriter, for distribution services were fair and reasonable in relation to the nature and quality of such services, the fees paid by competitive funds and the costs incurred by PRM and FD, as applicable, in providing such services.
