Convex Insurance

Specialty insurer for complex risks

Overview

Convex Group is an international specialty insurer and reinsurer that focuses on complex risks for large commercial clients. It underwrites a broad range of lines—property, casualty, and specialty areas such as aerospace, energy, marine, and financial lines—through direct underwriting and reinsurance, supported by a modern tech platform and outsourced operations to keep its underwriters focused. Led by veterans from Catlin and XL Catlin, it uses a legacy-free model and a partnership-based approach centered on fairness, transparency, and strong claims service. Its goal is to deliver expert underwriting for complex risks, maintain solid financial strength, and grow its global specialty insurance and reinsurance business, including the Lloyd’s Syndicate 1984 launched in 2025.

Simplify's take

What believers are saying

  • Onex and AIG backed Convex in February 2026, valuing equity at $7 billion.
  • Q3 2026 gross premiums reached $1.396 billion, up 20%, with 87% LTM combined ratio.
  • Kinetic launches in Q4 2026 and Syndicate 1987 started July 2026.

What critics are saying

  • Q3 2026 combined ratio jumped to 92.7%, showing underwriting discipline weakened.
  • AIG and Onex own 98% after February 2026, limiting independence and exit optionality.
  • A major catastrophe cycle would force capital support from Onex and AIG, threatening autonomy.

What makes Convex Insurance unique

  • Paul Brand and Stephen Catlin still anchor Convex’s underwriting culture and broker relationships.
  • Convex runs Bermuda, London, Luxembourg, and New Jersey platforms with dual Lloyd’s syndicates.
  • Its technology-enabled outsourcing model keeps expense ratios low and underwriting teams focused.

Convex writes $1.9bn in premiums. Created: Aug 14, 2026 05:44 PM AIG has acquired about a 35 per cent equity interest in Convex for approximately $2.1 billion (File photograph) Convex wrote $1.9 billion of gross premiums in the second quarter, up 8.1 per cent year on year, although net income fell 39 per cent to $169 million as its combined ratio rose to 85 per cent. The Bermudian-based speciality re/insurer said its combined ratio - a key measure of underwriting profitability - deteriorated from 80.7 per cent in the same period last year. A ratio below 100 per cent indicates underwriting profit. Net written premiums rose 4.7 per cent to $1.25 billion, while net premiums earned increased 6.5 per cent to $953 million. Over the 12 months to June 30, however, Convex reported net income of $719 million, excluding $41 million in one-off costs tied to the Onex and American International Group acquisition, up from $520 million a year earlier. Its combined ratio improved to 83.7 per cent from 94.2 per cent over the same period. Onex Corporation bought a 63 per cent stake in Convex in February this year for $4.9 billion along with AIG which acquired about a 35 per cent equity interest in Convex for approximately $2.1 billion, making it the second largest shareholder of the company founded in 2019 by industry veterans Stephen Catlin and Paul Brand with $1.7 billion in initial capital.

The combination of entrepreneurial underwriting, analytical rigour, and a relentless focus on portfolio performance creates an environment unlike any other in the market. I am excited to be rejoining the team and look forward to helping further enhance TFP's pricing, portfolio analytics and risk allocation capabilities as the business continues to grow."
