Vicor Corporation - June 2026
“During the second quarter of 2026, the Polen 5Perspectives Small Growth Composite Portfolio returned 33.22% gross and 32.83% net of fees, respectively, compared to the 25.71% return of the Russell 2000 Growth Index. • The top contributors to relative performance in the period were Bloom Energy, DigitalOcean Holdings, and Vicor. The most significant detractors from the Portfolio’s relative performance in the quarter were Fastly, Credo Technology Group (not owned), and GeneDx. • While concerns surrounding economic growth, trade policy, and the durability of the AI investment cycle weighed on markets early in the quarter, many of those fears quickly subsided as the quarter progressed. Investor sentiment sharply improved and small caps staged one of their best quarterly returns of the past 25 years with the Russell 2000 Growth +25.71%. • Companies with exposure to long-duration secular growth themes—including AI infrastructure, electrification, aerospace, and defense modernization—were among the strongest performers.

While concerns surrounding economic growth, trade policy, and the durability of the AI investment cycle weighed on markets early in the quarter, many of those fears quickly receded to the background as the quarter progressed. Investor sentiment sharply improved and small caps staged one of their best quarterly returns of the past 25 years with the Russell 2000 Growth +25.71%. One of the defining features of the quarter was the market's ongoing debate surrounding AI-related capital spending. Following periods of concern earlier this year that investment in AI infrastructure could moderate, a steady stream of announcements from hyperscalers and enterprise customers assuaged those concerns and instilled confidence for the market that spending growth would continue. Rather than slowing, the race to build AI infrastructure appears to be accelerating, benefiting a broad range of companies across power generation, electrical equipment, networking, and data center infrastructure. Related, the market's attention increasingly shifted toward power availability as one of the primary bottlenecks on future AI growth. As electricity demand forecasts continued to move higher, investors focused on companies positioned to benefit from the need to expand generation capacity, strengthen grid infrastructure, and provide alternative power solutions. This dynamic was particularly evident among Industrials and select Technology businesses tied to the broader Electrification theme. While geopolitical developments and trade policy headlines remained sources of volatility throughout the quarter, market leadership generally broadened as investor confidence improved. Companies with exposure to long-duration secular growth themes—including AI infrastructure, electrification, aerospace, and defense modernization—were among the strongest performers, while many areas tied more closely to cyclical economic concerns lagged. Portfolio Performance & Attribution During the second quarter of 2026, the Polen 5Perspectives Small Growth Composite Portfolio (the “Portfolio”) returned 32.83% (net of fees) compared to the 25.71% return of the Russell 2000 Growth Index (the “Index”). The top contributors to the Portfolio’s relative performance in the quarter were Bloom Energy, DigitalOcean Holdings, and Vicor.”
