Summary
Private equity has emerged as a transformative force in the accounting services industry, deploying approximately $50 billion into CPA firms over the past six years. This capital influx has fundamentally altered growth dynamics and consolidation patterns across the sector, particularly among mid-tier and smaller firms seeking expansion opportunities.

Chicago's Mowery & Schoenfeld, generating $48 million in annual sales, has bucked the prevailing trend by declining private equity investment. The firm's decision to forgo PE backing stands out against a broader industry consolidation wave, where five of the top 26 accounting firms have accepted PE stakes since 2021. PE-backed firms are positioning themselves as "super aggressive consolidators," signaling an intensifying battle for market share among accounting service providers.

The PE model in accounting firms prioritizes efficiency, speed, and profitability at scale—operational demands that reshape traditional firm cultures and partner economics. However, this ownership structure has introduced regulatory scrutiny. Audit independence faces potential threats under PE ownership, raising questions about the profession's ability to maintain standards and client trust as financial incentives shift toward PE-investor returns.

CPA firms currently face a strategic inflection point: pursue PE backing to accelerate growth and access consolidation opportunities, or maintain independence while competing against increasingly well-capitalized PE-backed rivals. The trajectory suggests PE will continue targeting accounting firms as attractive platform acquisitions, with continued consolidation likely as the industry reshapes around PE-backed operators.
