The $73.6 million firm is adding a Philadelphia-area practice and bringing its employees into the ownership plan.

In brief
• Prosperity Partners acquired Fabietti, Hale, Hammerstedt & Powers, its tenth announced deal.
• FHHP serves family-owned and closely held businesses around southern New Jersey and Philadelphia.
• FHHP employees will join Prosperity's broad-based employee ownership program.
Prosperity Partners has bought its way into another market. This time, the target is a firm founded in 1959 with deep ties to family-owned businesses around Philadelphia.
The deal gives Prosperity a local client base, an experienced team, and another office footprint. It also pushes the firm to ten acquisitions.
Terms were not disclosed.
A local firm with sticky clients
Fabietti, Hale, Hammerstedt & Powers serves closely held companies, individuals, trusts, estates, and other organizations across southern New Jersey and the greater Philadelphia area.
That mix matters. Family businesses and estate clients rarely buy one isolated service. They often need tax planning, financial reporting, succession help, trust work, and advice when ownership changes.
Prosperity says the combination will give those clients access to more specialized services, more capacity, and continued investment in technology and talent. The promise is familiar in accounting M&A. The hard part is delivering more without making a relationship-driven firm feel less personal.
The employee ownership piece
FHHP's team will enter Prosperity's Employee Purpose Plan, the firm's broad-based ownership program.
That is more than a recruiting line. Acquisitions create a basic retention problem: the people who carry client history can leave before the buyer captures the value it paid for.
Giving employees a stake can help align the old firm and the new platform. It does not guarantee retention, but it gives the team a reason to care about the combined firm's future instead of treating the transaction like someone else's payday.
Prosperity is building a map
The Chicago-based firm reported $73.6 million in revenue, 32 partners, 214 employees, and 10 offices before this deal. It ranked No. 94 on the 2026 Top 100 Firms list.
Its acquisition trail now reaches New York, Virginia, Vermont, Texas, California, Michigan, Maryland, and the Philadelphia market. That is not random office collecting. The firm is building a multi-market platform around advisory, accounting, and tax work for private businesses and their owners.
The capital structure has changed too. Lightyear Capital took a majority investment earlier in 2026, while prior investor Unity Partners kept a minority position. Prosperity had previously operated as NDH Advisors before its 2024 rebrand.
The integration test starts now
For clients, the early questions are practical. Will engagement teams stay intact? Who owns the relationship? Which systems, billing processes, and service lines change?
For the firm, the scorecard is just as clear. Keep the people. Keep the clients. Add useful services. Avoid turning a trusted local advisor into a confusing org chart.
Deal number ten makes Prosperity's strategy obvious. Whether it works will depend on what happens after the announcement.
