Pax World Management

What Pax World Management does

Pax World Management, founded in 1970 in Portsmouth, New Hampshire, is one of the pioneers of sustainable investing in the United States and operates as part of the broader Impax Asset Management Group. The firm specializes in the full integration of environmental, social, and governance (ESG) factors across investment portfolios, building strategies around the transition to a more sustainable global economy. Pax World is led by founders Luther Tyson and Jack Corbett, and the broader organization is structured with operating entities in the US (Impax Asset Management LLC), UK (Impax Asset Management Limited), and Ireland (Impax Asset Management Ireland Limited), under the publicly listed parent Impax Asset Management Group Plc.

The product platform comprises 10 mutual funds spanning US large cap, US small cap, global equities, environmental markets, gender lens (Global Women's Leadership), systematic quantitative US and International sustainable economy strategies, core and high yield fixed income, and multi-asset allocation. The firm also operates the Impax Global Sustainable Infrastructure ETF (NYSE: BLDX) and offers 18+ institutional strategies covering global listed equities (leaders, climate, water, sustainable food, social leaders, sustainable infrastructure), Asian equities, US equities, and a full fixed income range (core, core plus, US/global high yield, emerging markets corporate, short duration variants). The proprietary 'Sustainability Lens' investment methodology integrates ESG factors across portfolio construction and security selection.

The business model is asset management fee-based, generating recurring revenue through management fees on AUM across mutual funds, ETFs, and separately managed accounts. Distribution is multi-channel: direct institutional sales to pension funds, endowments, foundations, and sovereign wealth; intermediary distribution via Foreside Financial Services for US mutual funds; financial advisor networks with published fee breakpoints; NYSE exchange access for the ETF; and self-serve direct investor accounts. The firm maintains 8 global offices across North America, Europe, and Asia, and is supported by dedicated ESG research, stewardship and advocacy (now in ninth annual report edition), and a Policy & Advocacy function.
