Growth, Stability, and Capital: The 3 Signals Behind IMG's New CEO

SiriusPoint Ltd., a global specialty insurer and reinsurer, has appointed Will Nihan as the new Chief Executive Officer of its wholly owned subsidiary, International Medical Group (IMG). This change is effective on November 3, 2025, and Nihan will replace Adam Hirschfeld, who served as Interim CEO since March 2025 while retaining his General Counsel duties. Nihan brings extensive experience, having previously served as President and CEO of Travelex Insurance Services and holding senior roles at other major financial institutions.

SiriusPoint CEO Scott Egan expressed confidence in Nihan's ability to drive global transformation and growth for IMG, while also thanking Hirschfeld for his interim leadership. SiriusPoint is further described as a global underwriter with approximately $2.8 billion in capital, offering Property & Casualty and Accident & Health insurance and reinsurance solutions.

Corporate leadership announcements are more than just personnel updates; they are strategic signals about a company's future direction. The recent news that SiriusPoint has appointed Will Nihan as the new Chief Executive Officer of its subsidiary, International Medical Group (IMG), a leader in global insurance benefits and assistance services, is a prime example. This post decodes the three key strategic takeaways from this significant leadership change.

Takeaway 1: A Clear Mandate for Growth and Transformation

The selection of Will Nihan is a clear signal that the mandate is for aggressive growth and transformation, not just maintenance. His resume is not that of a caretaker but of a builder. As the former President and CEO of Travelex Insurance Services, he "drove top line growth, improved profitability and created a strong performance culture."

Critically, this experience is complemented by senior roles at Zurich Global Ventures, Prudential Financial, and AIG, providing him with a uniquely broad perspective.

This diverse background directly validates the strategic rationale outlined by SiriusPoint's CEO, Scott Egan.

"Will is a seasoned leader, with experience in driving global transformation and growth strategies. He brings strong experience of different products, sectors and geographies. We are excited for the future of IMG, and we are delighted to have Will join the team."

The appointment is an evidence-based bet that Nihan's proven ability to drive results across varied insurance landscapes is precisely what IMG needs to execute its next chapter of ambitious growth.

Takeaway 2: Blending New Vision with Institutional Stability

While bringing in an external change agent, SiriusPoint is masterfully de-risking the transition by ensuring leadership continuity. Adam Hirschfeld, who has served IMG for over 20 years, is not departing. Instead, after seven months as Interim CEO—a role he assumed alongside his General Counsel responsibilities—he will remain on the executive team to work closely with Nihan. This dual-hatted leadership is a powerful testament to his value and commitment.

This respect for deep institutional knowledge was underscored by Scott Egan.

“I would also like to extend my thanks to Adam Hirschfeld for leading IMG over the past seven months. He has done an excellent job and is a hugely valued member of the IMG family, having worked for the company for over 20 years.”

By retaining a leader who possesses such deep operational and legal knowledge of the business, SiriusPoint has created an environment where Nihan's transformative vision can be implemented on a stable and deeply understood foundation.

Takeaway 3: The Power of a Financially Strong Parent Company

IMG is not undertaking this new chapter alone. As a "wholly owned subsidiary" of SiriusPoint, a "global specialty insurer and reinsurer" listed on the NYSE (SPNT), it is backed by formidable financial strength.

This foundation is evidenced by approximately $2.8 billion in total capital and a suite of impressive financial strength ratings: A- (Excellent) from AM Best, S&P, and Fitch, as well as an A3 from Moody’s. This financial insulation grants the new CEO the strategic latitude to pursue long-term, capital-intensive transformation projects without being beholden to short-term market pressures—a critical advantage in the competitive global insurance landscape.

Conclusion: A New Chapter for IMG

The appointment of Will Nihan signals a new era for IMG, defined by a growth-focused leader, deep internal stability, and powerful financial backing from its parent company, SiriusPoint.

With all the pieces in place for a major transformation, what will this new chapter of leadership mean for the future of global insurance benefits?
