Key Decisions for Investors

• Investors seeking thematic exposure to the U.S. water resources sector, particularly those interested in ESG and sustainable finance themes focused on water conservation and purification, may find PHO a relevant, albeit concentrated, investment vehicle.
• Careful consideration should be given to PHO's medium risk profile, evidenced by its 1.01 beta and 19.01% standard deviation, alongside its 0.59% expense ratio and recent performance (4.63% YTD, 2.48% past year as of May 2025), when evaluating its suitability for a portfolio.
• Prospective investors should compare PHO with alternative water-focused ETFs such as CGW (0.56% expense ratio) and FIW (0.53% expense ratio), which offer slightly lower fees and may present different risk-return characteristics or diversification benefits due to their distinct underlying indices and portfolio compositions.
