Greenlight Capital Re, Ltd. $GLRE

The thesis

Greenlight Capital Re, Ltd., of Grand Cayman, provides multiline property and casualty insurance and reinsurance through its licensed and regulated reinsurers in the Cayman Islands and Ireland and its Lloyd's platform, Greenlight Innovation Syndicate 3456 (results release, Nov 2026). It invests through Solasglas Investments, LP, a related-party fund, and its Greenlight Re Innovations unit provides investment capital and risk capacity to technology companies in insurance (release). Our case is that a reinsurer earning an underwriting profit, with almost no debt, is buying back its shares well below book value, and that each share bought below book adds to the book value of the shares that remain.

The evidence

An underwriting profit. In the quarter to 30 September the combined ratio was 90.5%, against 86.6% a year earlier, for net underwriting income of $14.6M, down from $22.3M (release). Gross premiums written fell 1% to $181.9M and net premiums earned fell 7% to $153.4M; the Open Market segment wrote 10% less, at $138.8M, while the Innovations segment wrote $43.0M against $29.4M (release). Net income was $3.2M, or $0.10 a diluted share, against a loss of $4.4M, which the company puts mainly down to a smaller investment loss, led by gains from the partial divestiture of two Innovations investees, net of impairments (10-Q).

Book value up, price below it. Fully diluted book value per share was $20.78 at 30 September, up 0.8% in the quarter and 9.9% from $18.90 a year earlier; basic book value was $21.40 (release). The stock closed at $15.09 on 2 November, 27% below the fully diluted figure, for a market value of about $487M on the 32,240,043 shares outstanding at 30 October (10-Q, Yahoo Finance and Nasdaq). Debt was $4.8M against $694.5M of equity (release).

Buying back stock. The company bought 504,829 shares in the quarter at an average of $15.77, $8.0M, and $27.2M in the nine months at an average of $16.90, then 220,352 shares, $3.3M, from 1 to 30 October at $14.95 (release, 10-Q). Shares outstanding fell 4.8% in a year, to 32,460,395 at 30 September from 34,099,226 (release). At 30 September $28.1M was left under a $40.0M plan that runs from 15 May 2026 to 31 May 2027 (10-Q).

Insiders bought. Greg Richardson, the CEO, bought 30,000 shares at $12.63 on 6 November 2025 and 20,000 at $12.92 on 7 November in the open market, about $637,000 in all, and held 80,091 shares directly after (Form 4, Nov 2025). Director Leonard Goldberg bought 6,000 shares at $15.62 on 7 August 2026 and 6,000 at $15.42 on 10 August, through a family trust (Form 4, Aug 2026). No director or officer had a Rule 10b5-1 trading plan in the quarter (10-Q).

What the market is missing

The headline numbers move with Solasglas, which lost money in the quarter and the nine months, while the underwriting business earned $20.6M in the nine months (release, 10-Q). Buying shares at $15.77 when each carries $20.78 of fully diluted book value adds to the book value of every share left, and the company has kept doing it, at $14.95 in October (release). Fixed maturity investments grew to $178.9M at 30 September from $65.6M at the end of 2025 (release).

The risks

The investment side is the main risk. Solasglas held $487.4M at 30 September, 66.6% of the company's investments, and lost 3.3% in the quarter and 2.3% in the nine months (10-Q). Underwriting income fell by more than a third on a year earlier; the 10-Q says the higher loss ratio came mainly from more adverse development on prior-year reserves. Net premiums earned fell 7%, and a reinsurer's results swing with catastrophes and large losses (release, 10-Q). The nine-month net income of $9.4M was down from $25.6M, with a $6.0M foreign exchange loss against an $8.6M gain a year earlier (release). A family trust affiliated with chairman David Einhorn sells the company shares equal to 33% of the shares the company buys back from 5 November 2026 to 1 March 2027, at the same average price, because the company says a higher Einhorn ownership percentage would likely bring adverse tax consequences; the trust sold 106,060 shares to the company in the quarter and 120,335 on 30 October at $15.06 (8-K, 10-Q, Form 4).

What would change our mind

Fully diluted book value per share falling over the next two quarters; a combined ratio above 100% for the year; a halt to buybacks while the stock stays below book; or Solasglas losses large enough to take book value down on their own.
