Insights

Acquisition Synergy HORNE has joined BDO USA and expanded the Government Services practice, presenting opportunities to cross-sell government-focused accounting, advisory, and disaster recovery services to a broader federal and state client base.

Public Sector Focus Strong government, healthcare, franchise, and construction service footprint suggests upsell potential for compliance, program management, and state and local government consulting to existing BDO clients and the expanded HORNE portfolio.

Tech Ecosystem Current tech stack (Nessus, GitHub, WordPress, Sketch, GitLab, Fortinet, LinkedIn Sales Navigator, Slack) indicates readiness for cybersecurity, risk assessment, open-source collaboration, and digital transformation projects in regulated industries.

Financial Scale Operating revenue in the mid-market range and a sizable employee base signals capacity for larger, multi-year engagements in assurance, advisory, and government program services to large agency clients.

Growth Levers Recent corporate integration with BDO presents a door to joint marketing, expanded RFP access, and combined solutions in disaster recovery, compliance, and government program services to win larger contracts.
