Third Wave Insurance has entered into agreements to acquire five insurance and advisory agencies across Louisiana, Mississippi and Florida, creating a Gulf Coast operation spanning commercial property and casualty insurance, employee benefits, wealth management and self-funded health plan administration. The most consequential piece of this deal for other brokers isn't its geographic scale - it's that Third Wave is vertically integrating into plan administration, a capability most brokers currently refer out rather than own.
The acquisitions come about six months after TPG Growth launched Third Wave with Palmer & Cay as its flagship retail brokerage. TPG said at the time that the platform planned to expand through both organic growth and acquisitions. Following completion of the transactions, the five agencies will operate under the Palmer & Cay brand and be overseen by Jack Cay and the brokerage's existing management team. Financial terms were not disclosed.
The five-agency expansion stands out against a broader slowdown in insurance distribution deals. Buyers announced 292 insurance agency transactions in the United States and Canada during the first half of 2026, down 15% from the same period in 2025 and the lowest first-half total since 2016, according to OPTIS Partners data reported by Insurance Journal. Property and casualty agencies accounted for 198 transactions, or 68% of the total.
The businesses include Massad Olinde, a Baton Rouge-based employee benefits and retirement advisory firm; Acuity Group, a Ridgeland, Mississippi-based employee benefits brokerage; AWS, a commercial P&C agency serving the New Orleans market; Spielmann & Associates, a Lafayette-based wealth management and employee benefits adviser; and Alexander Financial Group, an Orlando-based commercial P&C agency.
Acuity Group also includes BAS, a third-party administrator for self-funded health plans. Its addition gives Third Wave an administrative capability alongside its employee benefits brokerage operations - and this is the piece of the deal worth other brokers' attention, because it changes what Third Wave can offer a large self-funded client relative to a broker who only advises on and places coverage.
Self-funding represents a substantial part of the employer health plan market. In 2025, 67% of workers with employer-sponsored coverage were enrolled in self-funded plans, including 80% of covered workers at companies with at least 200 employees, according to KFF. Among companies with 10 to 199 employees, 51% of covered workers were enrolled in either self-funded or level-funded arrangements, the latter generally combining employer funding, administrative services and stop-loss protection.
For a broker without in-house TPA capability, the practical question this deal raises is whether owning plan administration becomes a genuine competitive differentiator for winning and retaining large self-funded accounts, or whether it's primarily a margin play that captures administrative fees Third Wave would otherwise have referred to an outside TPA. The honest answer is probably both, and the balance likely depends on account size: for the largest self-funded clients, where claims data, plan design flexibility and a single point of accountability matter most, a broker that also owns the TPA relationship has a real structural advantage in retention conversations, since the client has fewer vendors to manage and one firm accountable for both advice and administration. For smaller self-funded and level-funded accounts, where standardized TPA platforms already handle most of the administrative load efficiently, owning a TPA matters less. Brokers competing for large self-funded business against Third Wave, or considering their own build-versus-partner decision on plan administration, should treat this deal as a data point that the largest platforms are choosing to own that capability rather than outsource it.
The P&C acquisitions also come as national commercial insurance pricing becomes more competitive. Average premiums across all account sizes declined 1.2% during the first quarter of 2026, the first overall decrease reported by The Council of Insurance Agents & Brokers' quarterly survey since the third quarter of 2017. Premiums declined an average of 2.7% for large accounts and 1.9% for medium-sized accounts, while small-account premiums increased 1.1%.
The national figures are not specific to catastrophe-exposed Gulf Coast accounts, but they provide broader context for Third Wave's expansion as brokers contend with changing pricing, underwriting appetite and competition for middle-market clients.
Massad Olinde will add employee benefits, retirement and wealth advisory operations in Baton Rouge. AWS and Alexander Financial Group will expand the platform's commercial P&C presence in Louisiana and Florida, while Spielmann & Associates will add wealth management and employee benefits operations in Lafayette.
"We built Third Wave as a modern insurance platform focused on investing in talented people and leveraging technology to deliver strong outcomes for clients," Third Wave Insurance CEO Brian Bair said. "These acquisitions are all high-quality businesses with strong reputations in their markets. We are excited to welcome their teams to Third Wave. These additions significantly expand our presence along the Gulf Coast and broaden the services we offer to middle-market clients."
Kelly Cox, a longtime Acuity Group executive, will lead the combined Gulf Coast operation and report to Cay. Cox has nearly three decades of experience in employee benefits, self-funded health care and regional operations.
