Grant Thornton LLP (US)'s Top Stability & Growth Strengths

Investor Backing & Capital Strength: A growth-oriented private equity investment from New Mountain Capital (with minority investments from CDPQ and OA Private Capital) in 2024 supplied an “investment war chest” to accelerate technology, AI-enabled services, talent acquisition, and strategic expansion.

The Advisors arm also combined with Grant Thornton Ireland in 2025 and has since grown its European footprint, signaling inorganic and international momentum.

Strong Market Position & Advantage: The firm is consistently ranked among the top U.S. accounting and professional services firms, operates across numerous U.S. offices, and is a premier leader for the mid‑market and private‑equity segments. Its inclusion among the small set of firms subject to annual PCAOB inspection underscores national scale and capital‑markets relevance.
