M&A roundup: EisnerAmper, BDO and Brady Martz expand

EisnerAmper, a Top 25 Firm based in New York, has added HDA Accounting Group, a firm in the Denver area that caters to dental practice clients.

The deal is expected to close in early 2025. Financial terms were not disclosed. 

HDA was founded in 2011 and has two partners and a staff of over 65 professionals. EisnerAmper has 450 partners and approximately 4,500 staff members; it ranked No. 17 on Accounting Today‘s 2024 list of the Top 100 Firms, with $848.7 million in annual revenue.

HDA provides services exclusively to dental practice owners and has over 800 dental practice clients across all 50 states. The firm offers tax compliance and planning, monthly accounting, benchmarking, profitability analytics and revenue advice, using proprietary software tailored to dental practices.

“This combination with EisnerAmper will allow us to enhance our clients’ experience through additional expertise, technology, and service offerings,” said HDA managing partner Morgan Hamon in a statement Thursday. “We can now offer our dental practice clients value-added advisory services such as cybersecurity, real estate, business valuation, wealth management and much more. We’re really excited about this big leap forward.”

EisnerAmper sees dental practices as an important niche for outsourced accounting.

“As the outsourced accounting sector becomes ever more focused on industry-tailored solutions, HDA represents a strategic move in both a key practice area and niche,” said Dan Gardiner, managing partner of outsourced solutions at EisnerAmper, in a statement. “We warmly welcome HDA and look forward to the exciting growth opportunities with EisnerAmper’s Health Care Group.”

Koltin Consulting Group CEO Allan Koltin advised both firms on the deal. “One reason for EisnerAmper’s continued growth has been its ability to add new, in-demand practice niches,” Koltin said in a statement. “This strategic pairing of EisnerAmper and HDA is all about the cultural fit along with the client-focused resources that each brings to the table.”

EisnerAmper has been busy on the M&A front since it received private equity funding in 2021 from TowerBrook Capital Partners, setting the stage for other accounting firms to follow its lead. The firm split into an alternative practice structure with Eisner Advisory Group LLC providing nonattest services and EisnerAmper LLP offering attest services to clients. Last fall, it added Tighe, Kress & Orr, a CPA firm based in Elgin, Illinois. In August, the firm announced it had added Krost CPAs, a Top 100 Firm based in the Los Angeles area, in a combination that’s expected to close this month. In May, it announced it would be adding Edelstein & Co., a Regional Leader based in Boston, in June, and in March, announced it was adding the Tidwell Group in Birmingham, Alabama. In 2023, it merged in Spielman Koenigsberg & Parker in New York, Morrison & Morrison in Chicago, and Top 100 Firm Postlethwaite & Netterville in Baton Rouge, Louisiana. In 2022, it added Lindsay & Brownell in La Jolla, California, Hoffman Group in Baltimore, Lurie in Minnesota and Florida, and Top 100 Firm Raich Ende Malter  and Popper & Co. in New York.
