American Century Sustainable Growth ETF (ESGY) is an actively managed exchange-traded fund that seeks to deliver competitive risk-adjusted returns through a large-cap growth equity portfolio integrating environmental, social, and governance (ESG) factors. The fund invests primarily in U.S. large-cap companies exhibiting improving business fundamentals and sustainable corporate behaviors, outperforming sector peers in managing ESG risks and opportunities; it employs a proprietary weighting scheme with approximately 85 holdings, concentrating around 62% of assets in its top 10 positions across sectors such as technology services (34.6%), electronic technology (29.1%), and retail trade (8.7%). Managed by a team including Joe Reiland, Rob Bove, Scott Marolf, and Rene Casis, the semi-transparent ETF publishes daily proxy portfolios while maintaining an expense ratio of 0.39%; it targets investors desiring positive impact alongside growth potential.
Headquartered in Kansas City, Missouri, as part of American Century Investments—a global asset manager founded in 1958 with over $300 billion in assets under management—the fund operates primarily in U.S. markets but holds minor international exposure (e.g., Ireland, Denmark). Geographically, its portfolio is overwhelmingly North American-focused (over 95% U.S. equities), serving institutional and retail investors seeking ESG-integrated large-cap growth strategies.
In a significant strategic shift, effective December 10, 2024, the fund was renamed American Century Large Cap Growth ETF and its ticker changed from ESGY to ACGR, reflecting an evolution from its explicit ESG branding while retaining active management and growth orientation. This rebranding aligns with broader American Century ETF lineup adjustments, including the 2021 launch of ESGY alongside income-focused peers like MUSI and AEMB to meet demand for differentiated active products. No recent acquisitions, partnerships, or funding rounds specific to the fund have been announced, though the issuer continues expanding its ETF offerings, such as the October 2025 launch of small-cap insights ETFs (ACSG and ACSV).
