The Doctors Company, a physician-owned insurer based in Napa, has officially closed its purchase of Birmingham-based ProAssurance in an all-cash deal valued at about $1.3 billion. The transaction pays $25 per share and folds ProAssurance into a larger physician-owned group that the companies say will control roughly $12 billion in assets. Together, the combined organization will insure more than 200,000 health care professionals and organizations across the country. ProAssurance will retain its name and operate as a wholly owned subsidiary while leadership conducts a post-closing review of its operating structure and systems.
Deal details
The final price tag came in at $25.00 per share in cash, putting the overall value of the transaction at about $1.3 billion. The companies say the merger closed last Friday. According to ProAssurance’s investor site, ProAssurance’s common stock will be deregistered and delisted from the New York Stock Exchange and the company will operate as a wholly owned subsidiary of The Doctors Company. The investor site also confirms the close and directs shareholders to payment details and frequently asked questions for post-closing logistics.
Executives on the deal
Company materials say the combined firm will lean on ProAssurance’s products and life sciences capabilities alongside The Doctors Company’s long-running physician-focused platform, according to The Doctors Company.
What this means for policyholders
For now, officials say it is business as usual. Existing policies remain in force, and insureds are being told to keep working with their current agents and brokers while the two companies align systems. ProAssurance’s investor site points policyholders and former shareholders to FAQs that walk through payment timing and certificate procedures. Company spokespeople say uninterrupted claims handling and on-time renewals are at the top of the to-do list as the integration gets underway.
Bigger picture
The acquisition marks another step in the ongoing consolidation of the medical malpractice market, leaving The Doctors Company and TDC Group as one of the largest physician-owned carriers, with roughly $12 billion in assets and more than 200,000 insureds on the books. As reported by Insurance Journal, the combined organization now sits just behind Berkshire Hathaway’s MedPro Group in overall scale. Documents filed with the SEC show that ProAssurance shareholders signed off on the plan in June 2025 and that state insurance regulators cleared the transaction ahead of last Friday's close; SEC filings lay out the approvals and timeline in detail.
Local reaction
The California Medical Association publicly backed the deal, saying physician ownership and California’s regulatory oversight would remain intact and would help protect consumers as the combined carrier grows. CMA issued its endorsement in February. Local coverage has cast the acquisition as a major milestone for the Napa-based insurer; see reporting in The Press Democrat for additional context.
