The sector includes companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment such as communications equipment, cellular phones, computers and peripherals, electronic equipment and related instruments, and semiconductors and related equipment and materials. Certain information technology companies, including semiconductor-related companies, may be particularly sensitive to supply and demand cycles, reduced demand for end-user products, underutilization of manufacturing capacity, inventory adjustments, high capital costs, reliance on a limited number of customers, suppliers, or specialized manufacturing facilities, shortages or price fluctuations in key components or raw materials, supply chain disruptions, research and development costs, trade restrictions, export controls, tariffs, intellectual property disputes, government regulation, and geopolitical developments.

These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. The rapid growth of artificial intelligence (“AI”) applications has significantly increased demand for products sold by semiconductor-related companies. If AI-related demand fails to meet market expectations, the value of these companies may substantially decline, resulting in a decline in the Portfolio’s value. Many companies involved in the information technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than the overall market, especially over the short term.</div> <div class="p0 ft0" style="text-align: left; padding-left: 230px; margin-top: 0px; margin-bottom: 0px; font: bold 15px 'arial'; line-height: 18px;"><span class="sec-hidden" style="-sec-ix-hidden: t_5_1adffc92_bde6_5bc7_a5ae_69aaebba42ae;">VOYA PARTNERS, INC.</span></div> <div class="p1 ft2" style="text-align: left; padding-left: 131px; margin-top: 0px; margin-bottom: 0px; font: 15px 'arial'; line-height: 17px;">VY<span class="ft1" style="font: 9px 'arial'; line-height: 12px;">^® </span>T.
