The Portfolio's prospectus and Statement of Additional Information, both dated May 1, 2024, as supplemented, are incorporated by reference into this Summary Prospectus.

Investment Objective

The Portfolio seeks total return which exceeds that of its benchmark.

Fees and Expenses of the Portfolio

This table describes the fees and expenses that you may pay if you buy, hold and sell Administrative Class shares of the Portfolio. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. Overall fees and expenses of investing in the Portfolio are higher than shown because the table does not reflect variable contract fees and expenses.

Shareholder Fees (fees paid directly from your investment):

N/A

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

	Administrative Class
Management Fees	0.71%
Distribution and/or Service (12b-1) Fees	0.15%
Other Expenses(1)	0.02%
Acquired Fund Fees and Expenses(1)	0.06%
Total Annual Portfolio Operating Expenses(2)	0.94%
Fee Waiver and/or Expense Reimbursement(3)	(0.04%)
Total Annual Portfolio Operating Expenses After Fee Waiver and/or Expense Reimbursement	0.90%

PIMCO Funds, PIMCO Equity Series and PIMCO ETF Trust indirectly incurred by the Portfolio in connection with its investments in series of PIMCO Funds, PIMCO Equity Series and PIMCO ETF Trust, up to a maximum waived amount that is equal to the Portfolio's aggregate advisory fee and supervisory and administrative fee. This waiver will automatically renew for one-year terms unless PIMCO provides written notice to the Trust at least 30 days prior to the end of the then current term.

Example.The Example is intended to help you compare the cost of investing in Administrative Class shares of the Portfolio with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 for the time periods indicated, and then hold or redeem all your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same. Although your actual costs may be higher or lower, the Example shows what your costs would be based on these assumptions. The Example does not reflect fees and expenses of any variable annuity contract or variable life insurance policy, and would be higher if it did.

	1 Year	3 Years	5 Years	10 Years
Administrative Class	$92	$296	$516	$1,151

Portfolio Turnover

The Portfolio pays transaction costs when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in the Annual Portfolio Operating Expenses or in the Example table, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 345% of the average value of its portfolio.

Principal Investment Strategies

The Portfolio seeks to achieve its investment objective by investing, under normal circumstances, in equity derivatives and other equity-related investments that provide equity-related exposure equivalent to 50-70% of its net assets (such portion of the Portfolio's Portfolio, the "Equity Sleeve") and the remainder of its net assets in a diversified portfolio of Fixed Income Instruments (such portion of the Portfolio's Portfolio, the "Fixed Income Sleeve"). "Fixed Income Instruments" include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The average portfolio duration of the Portfolio's Fixed Income Sleeve normally varies within 1 year (plus or minus) of the portfolio duration of the securities comprising the Bloomberg U.S. Aggregate Index, as calculated by PIMCO, which as of February 29, 2024 was 6.05 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.

The Equity Sleeve seeks to provide returns that are correlated to the returns of the S&P 500 Index and MSCI Europe Australasia Far East ("EAFE") Net Dividend Index (USD Unhedged) in proportion to their relative weights in the Portfolio's benchmark. Within the Equity Sleeve, the Portfolio will invest under normal circumstances in S&P 500 Index derivatives and MSCI EAFE Net Dividend Index (USD Unhedged) derivatives, backed by a portfolio of short-term Fixed Income

Instruments. Within the Equity Sleeve, the Portfolio will normally use equity derivatives instead of stocks to attempt to achieve the Portfolio's investment objective. However, the Portfolio may invest some or all of the net assets attributable to the Equity Sleeve in stocks. The value of equity derivatives should closely track changes in the value of underlying securities or indices. However, derivatives may be purchased with a small fraction of the assets that would be needed to purchase the equity securities directly, so that the remainder of the assets attributable to the Equity Sleeve may be invested in short-term Fixed Income Instruments.

The Fixed Income Sleeve seeks to provide returns that equal or exceed the returns of the Bloomberg U.S. Aggregate Index. Within the Fixed Income Sleeve, the Portfolio invests primarily in investment grade debt securities, but may invest up to 10% of its total assets in high yield securities ("junk bonds"), as rated by Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Services ("S&P") or Fitch Ratings, Inc. ("Fitch"), or, if unrated, as determined by PIMCO. In the event that ratings services assign different ratings to the same security, PIMCO will use the highest rating as the credit rating for that security. Within the Fixed Income Sleeve, the Portfolio may invest up to 15% of its total assets in securities denominated in foreign currencies, and may invest beyond this limit in U.S. dollar-denominated securities of foreign issuers. Within the Fixed Income Sleeve, the Portfolio will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 5% of its total assets. Within the Fixed Income Sleeve, the Portfolio may invest up to 5% of its total assets in securities and instruments that are economically tied to emerging market countries.

The Portfolio also may invest in affiliated and unaffiliated exchange-traded funds and mutual funds.

The Portfolio may invest, without limitation, in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities, subject to applicable law and any other restrictions described in the Portfolio's prospectus or Statement of Additional Information. Within the Fixed Income Sleeve, the Portfolio may invest up to 10% of its total assets in preferred securities. The Portfolio may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

Principal Risks

It is possible to lose money on an investment in the Portfolio. The principal risks of investing in the Portfolio, which could adversely affect its net asset value, yield and total return, are listed below.

Allocation Risk:the risk that the Portfolio could lose money as a result of less than optimal or poor asset allocation decisions. The Portfolio could miss attractive investment opportunities by underweighting markets that subsequently experience significant returns and could lose value by overweighting markets that subsequently experience significant declines

Equity Risk:the risk that the value of equity or equity-related securities, such as common stocks and preferred securities, may decline

due to general market conditions which are not specifically related to a particular company or to factors affecting a particular industry or industries. Equity or equity-related securities generally have greater price volatility than fixed income securities. In addition, preferred securities may be subject to greater credit risk or other risks, such as risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rates, regulatory changes and special redemption rights

Interest Rate Risk:the risk that fixed income securities will fluctuate in value because of a change in interest rates; a portfolio with a longer average portfolio duration will be more sensitive to changes in interest rates than a portfolio with a shorter average portfolio duration

Call Risk:the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer's credit quality). If an issuer calls a security that the Portfolio has invested in, the Portfolio may not recoup the full amount of its initial investment or may not realize the full anticipated earnings from the investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features

Credit Risk:the risk that the Portfolio could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivative contract, or the issuer or guarantor of collateral, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations

High Yield Risk:the risk that high yield securities and unrated securities of similar credit quality (commonly known as "junk bonds") are subject to greater levels of credit, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments, and may be more volatile than higher-rated securities of similar maturity

Market Risk:the risk that the value of securities owned by the Portfolio may go up or down, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industries

Issuer Risk:the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, changes in financial condition or credit rating, financial leverage, reputation or reduced demand for the issuer's goods or services

Liquidity Risk:the risk that a particular investment may be difficult to purchase or sell and that the Portfolio may be unable to sell illiquid investments at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may

be higher than normal, causing increased supply in the market due to selling activity

Derivatives Risk:the risk of investing in derivative instruments (such as forwards, futures, swaps and structured securities) and other similar investments, including leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative or other similar investment may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Portfolio could lose more than the initial amount invested. Changes in the value of a derivative or other similar instrument may also create margin delivery or settlement payment obligations for the Portfolio. The Portfolio's use of derivatives or other similar investments may result in losses to the Portfolio, a reduction in the Portfolio's returns and/or increased volatility. Non-centrally-cleared over-the-counter ("OTC") derivatives or other similar investments are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for non-centrally-cleared OTC derivatives or other similar investments. The primary credit risk on derivatives or other similar investments that are exchange-traded or traded through a central clearing counterparty resides with the Portfolio's clearing broker or the clearinghouse. Changes in regulation relating to a registered fund's use of derivatives and related instruments could potentially limit or impact the Portfolio's ability to invest in derivatives, limit the Portfolio's ability to employ certain strategies that use derivatives or other similar investments and/or adversely affect the value of derivatives or other similar investments and the Portfolio's performance

Mortgage-Related and Other Asset-Backed Securities Risk:the risks of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit risk. The Portfolio may invest in any tranche of mortgage-related and other asset-backed securities, including junior and/or equity tranches (to the extent consistent with the other of the Portfolio's guidelines), which generally carry higher levels of the foregoing risks

Foreign (Non-U.S.) Investment Risk:the risk that investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a portfolio that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, political changes, diplomatic developments or the imposition of sanctions and other similar measures. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

Emerging Markets Risk:the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

Sovereign Debt Risk:the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer's inability or unwillingness to make principal or interest payments in a timely fashion

Currency Risk:the risk that foreign (non-U.S.) currencies will change in value relative to the U.S. dollar and affect the Portfolio's investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies

Leveraging Risk:the risk that certain transactions of the Portfolio, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Portfolio to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss

Management Risk:the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO and the individual portfolio managers in connection with managing the Portfolio and may cause PIMCO to restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the Portfolio will be achieved

Short Exposure Risk:the risk of entering into short sales or other short positions, including the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale or other short position will not fulfill its contractual obligations, causing a loss to the Portfolio

Convertible Securities Risk:as convertible securities share both fixed income and equity characteristics, they are subject to risks to which fixed income and equity investments are subject. These risks include equity risk, interest rate risk and credit risk

LIBOR Transition Risk:the risk related to the discontinuation and replacement of the London Interbank Offered Rate ("LIBOR"). Certain instruments held by the Portfolio rely or relied in some fashion upon LIBOR. Although the transition process away from LIBOR for most instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or the continued use of LIBOR on the Portfolio, or on certain instruments in which the Portfolio invests, which can be difficult to ascertain and could result in losses to the Portfolio

Please see "Description of Principal Risks" in the Portfolio's prospectus for a more detailed description of the risks of investing in the Portfolio. An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information shows summary performance information for the Portfolio in a bar chart and an Average Annual Total Returns table. The information provides some indication of the risks of investing in the Portfolio by showing changes in its performance from year to year and by showing how the Portfolio's average annual returns compare with the returns of a broad-based securities market index. The Portfolio's performance information reflects applicable fee waivers and/or expense limitations in effect during the periods presented. Absent such fee waivers and/or expense limitations, if any, performance would have been lower. Performance shown does not reflect any charges or expenses imposed by an insurance company, and, if it did, performance shown would be lower. The bar chart and the table show performance of the Portfolio's Administrative Class shares. The Portfolio's past performance is not necessarily an indication of how the Portfolio will perform in the future.

The Portfolio's broad-based securities market index is the 35% S&P 500 Index / 25% MSCI EAFE Index / 40% Bloomberg U.S. Aggregate Index. The 35% S&P 500 Index / 25% MSCI EAFE Index / 40% Bloomberg U.S. Aggregate Index is a blended index. The S&P 500 Index is an unmanaged market index generally considered representative of the stock market as a whole. The S&P 500 Index focuses on the large-cap segment of the U.S. equities market. The MSCI EAFE (Morgan Stanley Capital International Europe, Australasia, Far East) Index is a free float-adjusted market capitalization index that is designed to measure the equity market performance of developed markets, excluding the US & Canada. The Bloomberg U.S. Aggregate Index represents securities that are SEC-registered, taxable, and dollar denominated. The Bloomberg U.S. Aggregate Index covers the U.S. investment grade fixed rate bond market, with index components for government and corporate securities, mortgage pass-through securities, and asset-backed securities. These major sectors are subdivided into more specific indices that are calculated and reported on a regular basis.

Performance for the Portfolio is updated daily and monthly and may be obtained as follows: daily updates on the net asset value may be obtained by calling 1-888-87-PIMCO and monthly performance may be obtained at www.pimco.com/pvit.

Payments to Insurance Companies and Other Financial Intermediaries

The Portfolio and/or its related companies (including PIMCO) may pay the insurance company and other intermediaries for the sale of the Portfolio and/or other services. These payments may create a conflict of interest by influencing the insurance company or intermediary and your salesperson to recommend a Variable Contract and the Portfolio over another investment. Ask your insurance company or salesperson or visit your financial intermediary's Web site for more information.
