The deal, expected to close in November, will add over 1,300 professionals and create a new government services subsidiary focused on disaster recovery.

BDO USA has announced its intention to combine with HORNE LLP, a professional services firm with a significant presence in the southern United States and Puerto Rico. The transaction will see more than 1,300 employees, including 30 principals, from HORNE join BDO, marking the firm's largest expansion to date. The deal is expected to close on November 1, 2025, pending regulatory approvals.

The move significantly expands BDO's geographic footprint across seven South and Southeastern states and substantially deepens its capabilities in the government sector. HORNE brings extensive experience in disaster recovery and federal program compliance, having managed over $126 billion in state and federal funding streams over the last 15 years.

As part of the integration, BDO will establish BDO Government Services, LLC, a new wholly owned subsidiary. This entity will be built around HORNE’s existing government services practice and its professionals in the continental U.S. and Puerto Rico. The combination also gives BDO a direct service presence for the government of Puerto Rico, where HORNE has maintained a team of over 130 professionals since 2018, primarily focused on recovery efforts following Hurricanes Irma and María.

"This strategic combination brings together two firms with complementary strengths and shared values," said Wayne Berson, CEO of BDO USA. Berson also pointed to the firm's employee stock ownership plan (ESOP) as a key factor in facilitating the expansion.

HORNE’s leadership cited cultural alignment as a primary reason for the move. "Joining BDO USA provides our people and clients with greater resources, capabilities, and solutions, expanding our ability to meet evolving needs," said Rusty Butcher, CEO and managing partner of HORNE LLP.

Upon completion, HORNE professionals will be integrated into BDO USA’s assurance, tax, advisory, and BDO Capital Advisors practices. The financial terms of the transaction were not disclosed.
