Key Takeaways
- • Private equity has deployed $29 billion into U.S. accounting firms across 53 notable transactions between 2020 and mid-2025, with projections indicating more than half of the largest 30 CPA firms will have PE investment or strategic partnerships by late 2025—a dramatic shift from 2020 when none had external PE ownership.
- • PE investors are employing two primary consolidation strategies: the platform model (acquiring a sizable firm and using it to purchase smaller regional practices for economies of scale) exemplified by Citrin Cooperman, Aprio, and EisnerAmper; and the umbrella/network model (maintaining independent operations under a parent company providing shared services) as seen with Ascend.
- • PE-backed accounting firms are prioritizing aggressive technology-driven growth strategies, including AI adoption and accelerated digital transformation, positioning themselves to address talent shortages and enhance operational efficiency across the sector.
- • Market observers highlight a dual concern: while PE investment enables strategic acquisition capability and operational scaling, critics warn that the profit-focused restructuring trend poses risks to audit quality, firm culture, and employee morale in an industry historically built on partnership-based governance models.
- • The upcoming 2026 election could materially impact PE acquisition velocity in public accounting, with potential regulatory or policy changes affecting equity-based ownership structures in CPA firms.
Summary
Private equity's penetration of the public accounting industry has accelerated into a transformational phase, reshaping one of America's most traditionally partnership-driven sectors. Between 2020 and mid-2025, PE investors completed 53 notable transactions representing $29 billion in capital deployment into U.S. accounting firms, according to analysis by CPA advisor Joseph Tarasco. By late 2025, more than half of the largest 30 U.S. accounting firms were projected to carry some form of PE investment or strategic partnership—a striking contrast to 2020, when no top-tier CPA firm had accepted external PE capital.
PE buyers have structured their accounting firm acquisitions around two primary models. The platform strategy involves acquiring a substantial anchor firm and using it as a consolidation engine to acquire smaller regional and specialty practices, generating economies of scale in technology, operations, talent management, and marketing. Market examples include Citrin Cooperman, Aprio, and EisnerAmper. An alternative approach—the umbrella or network model—maintains greater operational independence for acquired firms while centralizing shared services including technology infrastructure, HR, marketing, recruiting, and acquisition capital. Ascend exemplifies this decentralized ownership structure. Both models aim to expand service offerings and competitive reach while improving profitability metrics.
Technology acceleration represents a core value-creation thesis driving PE capital into accounting. According to industry reporting, PE-backed firms are pursuing aggressive technology-driven growth strategies, with particular emphasis on artificial intelligence capabilities and digital transformation initiatives. This technology push directly addresses a persistent sector challenge: talent shortages exacerbated by traditional promotion models that have historically favored technical skill advancement over business development or operational management.
However, PE's entry into public accounting has generated substantive debate within the industry. Proponents emphasize enhanced growth capability, strategic acquisition capacity, and operational modernization. Critics voice concerns that PE's profit-optimization mandate threatens audit quality, erodes partnership-based firm culture, and depresses employee morale—traditionally foundational elements of CPA firm identity. A survey cited in recent industry coverage found divided opinion: some practitioners view PE involvement favorably for growth acceleration, while others question long-term cultural sustainability and professional independence standards.
External factors could influence future PE activity in the sector. Industry observers note that the 2026 election outcome may impact PE's continued acquisition momentum, with potential regulatory or legislative changes potentially affecting equity ownership structures in accounting firms and the broader professional services landscape.
