Willis Re has appointed Jim (James) Summers as CEO of Global Specialties, effective immediately, drawing one of the longest-tenured marine and specialty broking executives from Guy Carpenter — and doing so despite a High Court ruling earlier this year that found Summers had shared confidential compensation data during the hiring process. On the same day, Arch Insurance International announced the elevation of independent non-executive director Kendra Felisky to Chair of the boards of Arch Insurance (UK) Ltd. (AIUK) and Arch Managing Agency Ltd. (AMAL), replacing Patrick Storey after nine years in the role. Together, the two announcements underscore how aggressively specialty platforms are investing in senior talent as the battle for Lloyd’s and international reinsurance market share intensifies.
Jim Summers: Four Decades of Marine Broking, One High Court Case, and a New Mandate at Willis Re
Summers brings more than 40 years of experience across the Lloyd’s and international reinsurance broking markets to his new role. He joined WTW’s relaunched Willis Re platform from Guy Carpenter, where he had served since 2011 as Deputy CEO, Global Specialties and Global Head of Marine & Energy Specialty (METL). Before that, he had been appointed CEO of Cooper Gay and Co Ltd. in 2006, cementing a career profile that runs from Lloyd’s box broking through senior management of a mid-market specialty firm and then nearly 14 years at the top of one of the two dominant reinsurance brokers.
Lucy Clarke, WTW president of risk and broking and a Willis Re board member, said in a statement reported by Insurance Journal: “Jim is one of the most respected leaders in the global specialty market, with an outstanding track record of building long-term client partnerships and high-performing businesses, making him an exceptional addition to the Willis Re leadership team.”
The appointment comes against a legally complicated backdrop. A High Court judgment handed down on February 24, 2026 ([2026] EWHC 361 (KB)) — widely reported by Insurance Business Magazine — found that Summers had breached his duties to Guy Carpenter by sharing confidential compensation data during Willis Re’s recruitment outreach, but rejected the broader allegation of a systematic, coordinated poaching conspiracy. Willis Re proceeded with the hire. The company’s decision to move forward reflects a calculated judgment that his market relationships and specialty expertise outweigh the legal friction — a posture that speaks to just how thin the bench of genuinely senior specialty broking talent is at this level.
The wider hiring campaign that preceded Summers’ own move was substantial. Court filings documented the scale of senior Guy Carpenter talent that migrated to Willis Re — a cohort large enough to anchor an independent reinsurance distribution platform. Willis Re was relaunched as a joint venture between Bain Capital (BCIS) and WTW, marking WTW’s return to treaty reinsurance after it had sold Willis Re’s treaty brokerage operations to Gallagher for $3.25 billion in 2021. Building a credible specialty practice from near-scratch in a market where the top four reinsurance brokers hold approximately 90% market share requires exactly the kind of embedded market relationships Summers carries.

Arch’s Counter-Move: Felisky Brings Actuarial Rigor to the London Specialty Chair
The Arch announcement is structurally different — a governance succession rather than an external hire — but it is no less deliberate. Felisky has served as an independent non-executive director on both AIUK and AMAL boards since February 2021, meaning Arch is promoting from within its own governance structure rather than importing an outsider unfamiliar with its underwriting culture and risk appetite framework.
Her professional profile is unusually quantitative for a board chair role. She previously led the general insurance actuarial practice at Deloitte and served as Chief Risk Officer at Travelers. She holds the designation of Fellow of the Casualty Actuarial Society and is a member of the Worshipful Company of Actuaries — credentials that position her to engage directly with the modelling and capital assumptions underpinning Arch’s Lloyd’s syndicate and insurance company vehicles.
Felisky’s elevation follows the retirement of Patrick Storey, who had chaired the boards for nine years and oversaw, among other milestones, Arch’s Consumer Duty compliance programme in the UK and what the company describes as more than trebling its GWP since 2019, now underwriting over $2 billion across more than 20 lines of business. Arch Capital’s group-wide insurance segment now spans more than $2bn across over 20 lines of business, providing context for how significant the UK platform is within the broader group.
Simultaneously, Jon Perkins — former Group Chief Actuary at Chaucer Group with more than 20 years at that firm — was named Chair of the Board Risk Committee across both AIUK and AMAL. The pairing of an actuarially credentialed Chair with an equally quantitative Risk Committee Chair signals that Arch is doubling down on technical governance depth at a moment when Lloyd’s faces continued pressure around model transparency and reserving adequacy. Hugh Sturgess, CEO of Arch Insurance International, said the appointment “reflects our commitment to strong, forward-looking governance,” according to reporting in Insurance Business Magazine.
This governance build-out at the specialty level mirrors a pattern visible elsewhere. When Berkshire Hathaway restructured its reinsurance leadership and when Swiss Re appointed Dean Galligan to lead L&H transactions, the common thread was the same: carriers and brokers building out specialist leadership structures that can operate with genuine technical authority, not merely managerial oversight.
The Willis Re vs. Guy Carpenter Talent War: What the High Court Actually Decided
The legal dimension of Summers’ hire deserves a factual summary for B2B readers who may need to assess its implications. Guy Carpenter brought proceedings against Willis Re and a group of former employees, arguing that the scale and coordination of Willis Re’s hiring campaign constituted a tortious conspiracy and breach of fiduciary duties. The High Court’s February 2026 judgment was split in outcome.
On the narrow question of Summers specifically, the court found he had improperly shared confidential Guy Carpenter compensation data with Willis Re during recruitment discussions prior to his resignation — a breach of duty to his then-employer. On the broader question of whether Willis Re orchestrated a systematic, unlawful raid, the court rejected that characterisation. The conspiracy allegation did not survive.
For Willis Re, the outcome was mixed but manageable. The firm hired Summers anyway, with the blessing of its board. From a market-positioning perspective, the episode illustrates the structural scarcity of experienced specialty broking leadership — the talent pool at Summers’ level is narrow enough that a High Court finding of a duty breach does not function as a market disqualifier when the skills on offer are sufficiently rare.
