Impax Asset Management’s “Impax US Sustainable Economy Fund” recently released its Q4 2025 investor letter, detailing the fund’s performance and key holdings. The letter highlighted that equity markets were volatile during the quarter, but the portfolio managed to outperform the Russell 1000 benchmark, thanks to sustainability tilts and stock-specific gains in sectors like Health Care and Financials.
In 2025, the Fund’s Institutional Class delivered a total return of 16.00%, slightly below the Russell 1000’s return of 17.37%. The performance was influenced by changing market leadership rather than macroeconomic factors, with gains in pharmaceutical and payment processing holdings offset by weakness in certain Consumer Staples names. Despite the challenges, management remains cautiously optimistic, citing falling interest rates, resilient corporate earnings, and investments in businesses poised to benefit from the shift towards a more sustainable economy.
One of the fund’s highlighted stocks in the Q4 2025 investor letter was Oracle Corporation (NYSE: ORCL). Oracle provides enterprise cloud infrastructure and software solutions, positioning itself at the forefront of AI-driven data center expansion and digital transformation initiatives. Despite a one-month return of -11.45%, Oracle Corporation traded between $118.86 and $345.72 over the last 52 weeks, closing at approximately $153.97 per share on February 17, 2026.
The fund noted that Oracle Corporation stands out for its strong sustainability profile, offering opportunities in Digital Infrastructure, Education, and Innovation. However, concerns arose over the company accumulating debt to finance its AI data center expansion, supported by OpenAI. While Oracle Corporation is not among the 30 Most Popular Stocks Among Hedge Funds, 122 hedge fund portfolios held the stock at the end of the third quarter.
While acknowledging the potential of Oracle Corporation as an investment, the fund believes that other AI stocks may offer greater promise for higher returns in a shorter time frame. For investors seeking undervalued AI stocks that could benefit from current economic trends, the fund recommends exploring their report on the best short-term AI stock.
In conclusion, Impax Asset Management’s “Impax US Sustainable Economy Fund” continues to navigate market challenges with a focus on sustainable investments and strategic stock picks like Oracle Corporation. With a cautiously optimistic outlook, the fund remains committed to delivering value for its investors in the evolving landscape of sustainable investing.
