Before you invest, you may want to review the Series’ statutory prospectus (and any supplements thereto), which contains more information about the Series and its risks. You can find the Series’ statutory prospectus and other information about the Series, including its statement of additional information and most recent reports to shareholders, online at delawarefunds.com/vip-literature. You can also get this information at no cost by calling 800 523-1918. The Series’ statutory prospectus and statement of additional information, both dated May 1, 2024 (and any supplements thereto), are incorporated by reference into this summary prospectus.

What is the Series’ investment objective?

Macquarie VIP Pathfinder Aggressive Series seeks to provide growth of capital consistent with a more aggressive level of risk as compared to the other Macquarie VIP Pathfinder Series.

What are the Series’ fees and expenses?

The following table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Series. The fee table and example do not reflect any fees or sales charges imposed by variable insurance contracts. If they did, the expenses would be higher.

Annual series operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Class	Service
Management fees	0.00%
Distribution and service (12b-1) fees	none
Other expenses	0.17%
Acquired fund fees and expenses	0.96%​1
Total annual series operating expenses	1.13%​2

1

Acquired fund fees and expenses sets forth the Series' pro rata portion of the cumulative expenses charged by the Underlying Funds (defined below) in which the Series invested during the last fiscal year. The actual acquired fund fees and expenses will vary with changes in the allocations of the Series' assets. The Acquired fund fees and expenses shown are based on the total expense ratio of each Underlying Fund for the Series’ most recent fiscal period. These expenses are not direct costs paid by Series shareholders, and are not used to calculate the Series' NAV.

The Total annual series operating expenses ratio shown above does not correlate to the expense ratio shown in the Financial Highlights table because that ratio does not include the Acquired fund fees and expenses.

Example

This example is intended to help you compare the cost of investing in the Series with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Series for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	Service
1 year	$115
3 years	$359
5 years	$622
10 years	$1,375

Summary prospectus

Portfolio turnover

The Series does not incur transaction costs, such as commissions, when it buys and sells shares of underlying funds, but it could pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Series shares are held in a taxable account. These costs, which are not reflected in the annual series operating expenses or in the example, affect the Series' performance. During the most recent fiscal year, the Series' portfolio turnover rate was 34% of the average value of its portfolio.

What are the Series’ principal investment strategies?

Macquarie VIP Pathfinder Aggressive Series seeks to achieve its objective by allocating its assets among asset classes so that approximately 75-95% of the value of the Series' assets are in equities (with a maximum of 35% allocated to international/global stocks) and approximately 5-25% of the Series' assets are in fixed income (including cash). The Series implements this allocation by investing primarily in other Delaware Funds (Underlying Funds). The Series typically will invest in Standard Class shares of an Underlying Fund. To the extent an Underlying Fund does not offer Standard Class shares, the Series generally will invest in Service Class shares of such Underlying Fund. Shorter-term allocations may vary from the target ranges described above. For the most current list of Underlying Funds in which the Series invests, please see the Series' most recent shareholder report or Series holdings disclosures. For more information about the investment strategies and risks of an Underlying Fund, see such Underlying Fund's prospectus.

These allocations are projections only and may be changed by Delaware Management Company (Manager), the Series' investment manager, from time to time. Actual allocations are not limited to the ranges described above and may vary. The Manager monitors the Series' holdings and cash flow and will periodically adjust the Series' asset allocation to realign it with the Series' risk profile and investment strategies. The Manager evaluates the Series' asset allocation on an ongoing basis in view of its risk profile and strategies. This means that allocation changes will be made as needed in the view of the Manager. The Manager applies a long-term investment horizon with respect to the Series; therefore, allocation changes may not be made in response to short-term market conditions. The Series does not intend to actively trade among the Underlying Funds, nor does it intend to attempt to capture short-term market opportunities.

By owning shares of the Underlying Funds, the Series indirectly holds a well-diversified mixture of both growth-oriented and value-oriented US and international/global stocks and, to a lesser extent, a mixture of investment-grade and non-investment-grade corporate bonds and US government securities, and money market instruments. Although the majority of the Series' indirect stock holdings are of US and foreign large-capitalization companies, the Series may have potentially significant exposure to mid-capitalization companies and small-capitalization companies.

The Series is intended for aggressive investors comfortable with incurring the risk associated with growth investing and investing in a high percentage of stocks, including foreign stocks, investors with long-term time horizons or investors who want to maximize long-term returns and who have a higher tolerance for possible short-term losses.

What are the principal risks of investing in the Series?

Investing in any mutual fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Series will increase and decrease according to changes in the value of the securities in the Series’ portfolio. An investment in the Series may not be appropriate for all investors. The Series’ principal risks include:

Market risk — The risk that all or a majority of the securities in a certain market — such as the stock or bond market — will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.

Asset allocation risk — The risk associated with the allocation of a series’ assets amongst varying underlying styles. Portfolio managers may make investment decisions independently of one another, and may make conflicting investment decisions which could be detrimental to a series’ performance. There is a risk that the allocation of assets may skew toward a category or underlying fund that performs poorly relative to other categories or funds, or to the market as a whole, which could result in a series performing poorly.

Derivatives risk — Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in the opposite direction from what the Manager anticipated. When used for hedging, the change in value of the derivatives instrument may also not correlate specifically with the currency, rate, or other risk being hedged, in which case a series may not realize the intended benefits. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to, among other reasons, financial difficulties (such as a bankruptcy or reorganization).

Fund of funds risk — The ability of a fund of funds to meet its investment objective is directly related to its investments in underlying funds and the ability of those funds to meet their investment objectives. A fund of funds’ share price will likely change daily based on the performance of the underlying funds in which it invests. In general, a fund of funds is subject to the same risks as those of the underlying funds it holds.

2

Equity funds risk. The Series invests in underlying equity funds that are subject to market risk. Market risk is the risk that all or a majority of the securities in a certain market — such as the stock or bond market — will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.

Bond funds risk. The Series invests in underlying fixed income funds that are subject to fixed income risk. Fixed income risk is the risk that bonds may decrease in value if interest rates increase; anissuer may not be able to make principal and interest payments when due; a bond may be prepaid prior to maturity; and, in the case of high yield bonds (“junk bonds”), such bonds may be subject to an increased risk of default, a more limited secondary market than investment grade bonds, and greater price volatility. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. A series may be subject to a greater risk of rising interest rates when interest rates are low or inflation rates are high or rising.

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected by political instability, changes in currency exchange rates, inefficient markets and higher transaction costs, foreign economic conditions, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards.

Investment company securities risk — The risk that when a series invests in another investment company, shareholders of the series bear their proportionate share of the other investment company’s fees and expenses as well as their share of the series’ fees and expenses, which could result in the duplication of certain fees. Investment in other investment companies also typically reflects the risks of the types of securities in which the investment companies invest.

Leveraging risk — The risk that certain portfolio transactions, such as reverse repurchase agreements, short sales, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivatives instruments, may give rise to leverage, causing a series to be more volatile than if it had not been leveraged, which may result in increased losses to the series.

Other risks applicable to a fund of funds structure — There are other risks associated with a fund of funds structure. The Manager has the authority to select and replace underlying funds. The Manager is subject to a potential conflict of interest in doing so because the Manager serves as the investment manager to the affiliated underlying funds and the advisory fees paid by some of the affiliated underlying funds are higher than fees paid by other underlying funds. It is important to note, however, that the Manager has a fiduciary duty to the Series and must act in the Series' best interests.

Liquidity risk — The possibility that investments cannot be readily sold within seven calendar days at approximately the price at which a series has valued them.

IBOR risk — The risk that changes related to the use of the London Interbank Offered Rate (LIBOR) or similar interbank offered rates (“IBORs,” such as the Euro Overnight Index Average (EONIA)) could have adverse impacts on financial instruments that reference LIBOR or a similar rate. While some instruments may contemplate a scenario where LIBOR or a similar rate is no longer available by providing for an alternative rate setting methodology, not all instruments have such fallback provisions and the effectiveness of replacement rates is uncertain. The abandonment of LIBOR and similar rates could affect the value and liquidity of instruments that reference such rates, especially those that do not have fallback provisions. The use of alternative reference rate products may impact investment strategy performance.

Active management and selection risk — The risk that the securities selected by a series’ management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.

How has Macquarie VIP Pathfinder Aggressive Series performed?

The bar chart and table below provide some indication of the risks of investing in the Series by showing changes in the Series’ performance from year to year and by showing how the Series’ average annual total returns for the 1-, 5-, and 10-year periods compare with those of a broad measure of market performance. On April 30, 2021, the Series became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Series' investment manager. The returns shown from before April 30, 2021 are from the Series' prior investment manager. The Series’ past performance is not necessarily an indication of how it will perform in the future. The returns reflect any expense caps in effect during these periods. The returns would be lower without the expense caps.

Please refer to the Fund’s prospectus and statement of additional information for more details regarding the purchase and sale of Fund shares.

Tax information

The dividends and distributions paid from the Series to the insurance company separate accounts will consist of ordinary income, capital gains, or some combination of both. Because shares of the Series must be purchased through separate accounts used to fund variable annuity contracts or

variable life insurance contracts (variable contracts), such dividends and distributions will be exempt from current taxation by contract holders if left to accumulate within a separate account. You should refer to your variable contract prospectus for more information on these tax consequences.

Payments to broker/dealers and other financial intermediaries

If you purchase shares of the Series through a broker/dealer or other financial intermediary (such as an insurance company), the Series and its related companies may pay the intermediary for the sale of Series shares and related services. These payments may create a conflict of interest by influencing the broker/dealer or other intermediary and your salesperson to recommend the Series over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
