We are pleased to welcome them to the Ambac family as a highly valuable addition to our platform.”

Ed Walker, Chief Executive Officer of ArmadaCare, said, “We could not be more excited to join the Ambac family of MGAs. Ambac’s commitment to empowering their MGAs, coupled with our deep relationships with long-term underwriting partners, will fuel the continued growth and future success of our business and further establish our position as a leading health insurance solutions provider.”

Scott Egan, Chief Executive Officer of SiriusPoint, added, “We are delighted to continue our long-term capacity agreement with Armada and look forward to the team continuing to drive strong underwriting performance for our Accident and Health segment. We wish the team well for an exciting new chapter under the ownership of Ambac.”

• Deeply Integrated Carrier Relationships, Based on Long-Term Track Record of Performance: ArmadaCare will continue its valued partnership with current capacity providers, including through a new five-year commitment with SiriusPoint.
• Complementary Capabilities with Revenue Synergy Opportunities: ArmadaCare offers a highly complementary product offering to Ambac’s existing A&H businesses, providing a strong distribution network with direct C-suite access, bringing significant cross-sell opportunities.
• Strengthens Financial Profile: The transaction is expected to materially accelerate Ambac’s path toward its 2028 EBITDA targets and become accretive to Ambac shareholders by 2026, delivering clear and measurable value creation.
