For Class C shares, a 1% CDSC applies to redemptions within 12 months of purchase.

2	“Other expenses” account for Class R6 shares not being subject to certain expenses as described further in the section of this Prospectus entitled “Choosing a share class.”

The Fund’s investment manager, Delaware Management Company (Manager), has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any 12b-1 fees, acquired fund fees and expenses, taxes, interest, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and nonroutine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations) in order to prevent total annual fund operating expenses from exceeding 0.99% of the Fund’s average daily net assets for all share classes other than Class R6, and 0.84% of the Fund’s Class R6 shares’ average daily net assets, from July 31, 2026 through July 30, 2027. These waivers and reimbursements may only be terminated by agreement of the Manager and the Fund.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. In addition, the example shows expenses for Class C shares, assuming those shares were not redeemed at the end of those periods. The example also assumes that your investment has a 5% return each year and reflects the Manager’s expense waivers and reimbursements for the 1-year contractual period and the total operating expenses without waivers for years 2 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


Class	A	(if not redeemed) C	C	Inst.	R6	R	Y
1 year............	$694	$202	$302	$101	$86	$152	$126
3 years...........	$1,022	$703	$703	$396	$345	$551	$474
5 years...........	$1,372	$1,231	$1,231	$714	$625	$976	$846
10 years..........	$2,356	$2,677	$2,677	$1,613	$1,423	$2,159	$1,890

Portfolio turnover

The Fund pays 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 Fund shares are held in a taxable account. These costs,

which are not reflected in the annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

Nomura Climate Solutions Fund seeks to achieve its objective by investing in securities of U.S. and non-U.S. issuers, including non-dollar securities and securities of emerging market issuers. The Fund focuses its investments on equity securities and equity-related investments and may invest in common and preferred stocks, convertible securities and warrants of companies of any market capitalization. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of companies that the Manager and Van Eck Associates Corporation (the “Sub-Advisor”, together the “Management Team”) has identified as being capable of reducing, displacing and/or sequestering greenhouse gas (GHG) emissions or helping others to do so (80% policy). For purposes of the Fund’s 80% policy, the Fund includes companies that the Management Team has identified as being either a “reducer” or “facilitator” as described in the following paragraph.

The Management Team’s investment process for the Fund begins with idea generation, focusing on the identification of companies capable of reducing, displacing, and/or sequestering GHG emissions or helping others to do so. The Management Team’s investment process is designed to identify both “reducers” and “facilitators” for inclusion in the Fund’s portfolio. Companies identified as “reducers”, i.e., those reducing, displacing, and/or sequestering their own GHG emissions, are willing and able to make reductions in their absolute GHG emissions. Within these “reducer” companies, the Management Team gives preference to companies that are able to demonstrate a commitment to help remain on a transition pathway towards the goals of the United Nations Climate Change Paris Agreement of 2015 (Paris Agreement) by 2050. Companies identified by the Management Team as “facilitators”, i.e., those helping others reduce emissions, offer products and/or services that help reduce GHG emissions primarily through displacement and/or sequestration.

The ability of the Fund to measure a company’s progress as a reducer or facilitator is, to a significant extent, contingent on the information disclosed by the company. Data on emissions is sourced from company web sites, corporate sustainability reports, and third-party sources such as non-governmental organizations, sell-side research, and, on a limited basis, environmental, social and governance (ESG) data providers. For “reducers,” the Management Team will source the most recent reported Scope 1 and Scope 2 emissions. To estimate a company’s emission reduction by 2030, the Management Team will subtract current emissions from estimated emissions by 2030. Estimated emissions are sourced from company-disclosed targets and/or estimates from the Transition Pathway Initiative, which is a global, asset-owner led initiative that assesses companies’ preparedness for the transition to a low carbon economy. Some company-level emission estimates will be calculated by applying forecasted changes in carbon intensity on a percentage basis and applying that change to a base level of emissions. For

“facilitators,” measurement is based on annual estimated GHG emissions saved in comparison to existing higher GHG-emitting alternatives. Because company GHG emissions data are not standardized (and are further subject to estimation error when not company-reported), the data sets the Management Team must rely on may imperfectly represent companies’ true GHG emissions. Additionally, the company emissions targets that the Management Team sets are based on model assumptions and estimations that carry the inherent risk associated with any modeling or estimating process.

From this universe of companies identified pursuant to the process described above, companies with perceived superior financial risk-adjusted returns are selected. This selection process includes cash flow, earnings and net asset value analysis combined with a strong financial profile and balance sheet. The Management Team will also review a company’s corporate governance, shareholder alignment and capital allocation.

The Fund is nondiversified, meaning that it may invest a significant portion of its total assets in a limited number of issuers. In addition, the Fund has a policy to concentrate (invest at least 25% of its net assets under normal circumstances) in companies within the energy industry. Companies in the energy industry include, but are not limited to, oil companies, oil and gas drilling, equipment and services companies, oil and gas exploration and production companies, oil and gas storage and transportation companies, natural gas pipeline companies, refinery companies, energy conservation companies, coal, transporters, utilities, alternative energy companies and innovative energy technology companies. Notwithstanding the foregoing, the Fund may also invest its assets across different industries outside of the energy industry.

What are the principal risks of investing in the Fund?

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 Fund will increase and decrease according to changes in the value of the securities in the Fund’s portfolio. An investment in the Fund may not be appropriate for all investors. The Fund’s principal risks include:

Climate change investment focus risk — The Fund’s focus on securities of issuers that seek to reduce, displace and/or sequestor GHG emissions or help other to do so may affect the Fund’s exposure to certain sectors or types of investments. The Fund’s relative investment performance may also be impacted depending on whether such sectors or investments are in or out of favor with the market. Certain investments may be dependent on U.S. and foreign government policies, including tax incentives and subsidies, as well as on political support for certain environmental initiatives and developments affecting companies focused on sustainable energy and climate change solutions generally.

ESG screening risk — Using ESG criteria in the investment process may exclude certain companies for non-investment reasons and, therefore, the Fund may forgo some market opportunities available to funds that do not use ESG factors. In addition, because company GHG emissions data are not standardized (and are further subject to estimation error when not

company-reported), the data sets the Fund must rely on may imperfectly represent companies’ true GHG emissions. Also, the company emissions targets that the Management Team sets are based on model assumptions and estimations that carry the inherent risk associated with any modeling or estimating process.

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.

Nondiversification risk — A nondiversified fund has the flexibility to invest as much as 50% of its assets in as few as two issuers with no single issuer accounting for more than 25% of the fund. The remaining 50% of its assets must be diversified so that no more than 5% of its assets are invested in the securities of a single issuer. Because a nondiversified fund may invest its assets in fewer issuers, the value of its shares may increase or decrease more rapidly than if it were fully diversified.

Concentration risk — The risk that a concentration in a particular industry will cause a fund to be more exposed to developments affecting that single industry or industry group than a more broadly diversified fund would be. A fund could experience greater volatility or may perform poorly during a downturn in the industry or industry group because it is more susceptible to the economic, regulatory, political, legal and other risks associated with those industries than a fund that invests more broadly.

Utilities sector risk — Companies in the utilities sector face a wide range of challenges that may adversely impact their operations, profitability, and securities. These include sensitivity to interest rate fluctuations, financing difficulties, and the high costs associated with capital-intensive projects, particularly during periods of inflation or unsettled markets. Government regulation plays a significant role, as restrictions on rates charged to customers, environmental compliance costs, and delays due to regulatory approvals can constrain profitability. Additionally, technological advancements may render existing infrastructure obsolete, and natural or man-made disasters, including wildfires, may lead to substantial liabilities or operational disruptions. Companies in this sector may also be affected by energy conservation policies, climate-related regulations, and fluctuations in commodity prices, all of which could reduce demand or increase operating costs. Renewable energy and alternative energy companies face unique risks, such as short product cycles, technological obsolescence, and stricter regulatory oversight.

Industry and sector risk — The risk that the value of securities in a particular industry or sector (such as utilities) will decline because of changing expectations for the performance of that industry or sector.

Initial public offering (IPO) risk — The risk that any positive effect of investments in IPOs may not be sustainable because of a number of factors. Namely, a fund may not be able to buy shares in some IPOs, or may be able to buy only a small number of shares. Also, the performance of IPOs generally is volatile, and is dependent on market psychology and economic

conditions. To the extent that IPOs have a significant positive impact on a fund’s performance, this may not be able to be replicated in the future. The relative performance impact of IPOs also is likely to decline as a fund grows.

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

Foreign and emerging markets risk — The risk that investments in foreign securities (particularly those of issuers 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. Securities of issuers in emerging markets may be subject to greater risks than securities of issuers in more developed foreign markets because, among other things, emerging markets may have less stable political and economic environments. In addition, there often is substantially less publicly available information about issuers and such information tends to be of a lesser quality. Economic markets and structures tend to be less mature and diverse and the securities markets may also be smaller, less liquid, and subject to greater price volatility.

Foreign currency exchange transactions and forward foreign currency contracts risk — The risk that a fund’s use of foreign currency exchange transactions and forward foreign currency contracts to hedge certain market risks (such as interest rates, currency exchange rates and broad or specific market movement) may increase the possibility of default by the counterparty to the transaction and, to the extent the Manager’s judgment as to certain market movements is incorrect, the risk of losses that are greater than if the investment technique had not been used.

Currency risk — The risk that fluctuations in exchange rates between the US dollar and foreign currencies and between various foreign currencies may cause the value of an investment to decline.

Government and regulatory risk — The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance.

Active management and selection risk — The risk that the securities selected by a fund’s 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.
