Sax, a Top 75 Firm based in Parsippany, New Jersey, has received a minority investment from Cobepa, a private equity firm with offices in Brussels and New York, the latest firm to receive a PE investment.
As is common with PE deals, Sax will restructure to accommodate the investment, providing attest services through Sax LLP, a licensed CPA firm, and advisory, consulting and other professional services through Sax Advisory Group. The firm plans to preserve its independence without disrupting client engagements or relationships.
Sax plans to pursue strategic acquisitions to expand its footprint along the East Coast, improve its service offerings and drive further technological innovation across its practice areas.
“I think our deal is much different than the rest of the industry in that we are selling on a fully diluted basis less than 20%, so it’s a very, very minority deal,” said Sax Advisory Group CEO Joseph Damiano. “We’re going to use a lot of the money to go out and grow the practice and for investments in technology. It’s an exciting part of Sax history.”
The firm dates back to 1956. “We’re going to reach 70 years old next year in 2026, and I think this is probably the most exciting day of Sax history as we take this journey,” Damiano said. “I took over in 2015 and the firm was about a $25 million firm. In 2025, we’ll probably do revenues of $130 million. In a very short period of time of nine years, it’s really taken off for the firm. It’s been a fun ride to get there, but now we want to take it to the next level. We saw the industry changing. So many firms were taking private equity deals, but we are still an independent firm and trying to get the best of both worlds, getting a minority partner that was willing to basically let me run the firm the way I want to run the firm and go forward and join us in that group journey.”
Sax is contributing $1 million to its charity, the Sax Foundation. The firm has been heavily involved in fundraising and charitable work .
“Today marks a historic day in Sax’s history with our PE investment that well positions the firm for continued and sustainable growth as we move towards the Top 50 bracket,” said Peter J. Scalise, national partner-in-charge of Sax’s Federal Tax Credits & Incentives Practice, who has been spearheading many of the firm’s philanthropic efforts, teaming up Sax with other firms in the Accounting Industry Leadership Council to support causes like the Alzheimer’s Association, the USO and the American Cancer Society.
Sax lost out on some M&A deals that were able to leverage the private equity model. “Now we should be able to compete on those deals,” said Damiano. “We have a better story than a lot of the firms, so it’s an exciting time to be a Sax partner.”
“Our investment in SAX is a direct result of their proven business model, strong leadership team and client-first culture,” said Andrew Hollod, managing director North America for Cobepa, in a statement. “We share a common vision for the business and believe that our “hands-with” approach will unlock compelling opportunities to continue growing the company and expanding its reach while maintaining the same high-quality client service that defines the firm.”
The deal was facilitated by Houlihan Lokey, represented by managing director Louis Trimble. Sax was advised by Lowenstein Sandler, led by Nicholas San Filippo IV, and Vedder Price, led by Steven R. Berger. Cobepa was advised by Weil, Gotshal & Manges LLP, led by Luke Laumann.
Financial terms of the deal were not disclosed. Sax ranked No. 66 on Accounting Today‘s 2025 list of the Top 100 Firms, with $109 million in annual revenue. Last month, Sax acquired Sewald & Anastasia, based in Parsippany, New Jersey. Damiano hopes to build Sax into a Top 50 Firm and a Top 20 Firm in terms of assets under management on Accounting Today‘s Wealth Magnets list. It currently has a little under $4 billion in assets under management.
Sax is in discussions with three other CPA firms and three wealth management firms.
Damiano declined to specify the amount of the investment from Cobepa, which operates a $5.9 billion fund. “They’ve been looking in the accounting space for a while now for the right partner, and hopefully they found that in us,” he said. “They’re a little bit unique in that they have a closed fund, and they don’t really accept new money. They’re made up of five families. They are a family office from very wealthy families that have basically contributed their money together to create a private equity firm that continues to grow.”
Sax also solidified a $40 million acquisition line of credit with Valley Bank, its existing bank, with an accordion feature of up to $75 million.
“I think we have a very unique deal that’s not similar to any of the other deals,” said Damiano. “Part of what we did is we’ve created a couple of different ways for the younger generation to share this, and we want to make sure that the younger generation that wants to become equity partners in the future have that same ability to become an equity partner as we have.”
