Harrison Street Infrastructure Active ETF (NFRX) is an actively managed exchange-traded fund that seeks total return by investing primarily in equity and debt securities of infrastructure companies across sectors including energy, transportation, utilities, and digital infrastructure. The fund offers exposure to a diversified portfolio of infrastructure assets, such as renewable energy projects, data centers, broadband networks, toll roads, and water utilities; it employs a fundamental research-driven approach to select securities with strong cash flow potential and resilience to economic cycles, targeting mid- to large-cap issuers globally with a focus on North America. Launched in 2024 by Tidal Investments LLC as investment adviser, with sub-advisory services provided by Harrison Street Real Assets Managers LLC, NFRX is headquartered in Milwaukee, Wisconsin, and operates without a fixed geographic restriction but emphasizes developed markets in the U.S., Europe, and select emerging regions. In late 2025, the fund announced a strategic expansion of its digital infrastructure allocation following a key partnership with leading data center operators, enhancing its exposure to AI-driven demand; it also completed a seed capital raise exceeding $100 million from institutional infrastructure investors, supporting portfolio growth amid rising interest in sustainable assets.
