PLGO vs RNR: How Pelagos Insurance Capital and RenaissanceRe Holdings Compare (2026)

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: PLGO is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. PLGO and RNR share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined PLGO and RNR exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

Pelagos Insurance Capital writes specialty insurance and reinsurance from Bermuda, with underwriting entities in Bermuda, the Republic of Ireland and the United Kingdom, and reports in two segments, Insurance and Reinsurance. The lines are the ones that make headlines when something goes wrong: property and property catastrophe, marine, energy, aviation and aerospace, political risk, violence and terror, cyber, and asset-backed finance and portfolio credit. The company also participates at Lloyd's, taking a ~7.4% share of Syndicate 3123 for the 2025 and 2026 years of account and adding participations in other Lloyd's syndicates from January 1, 2026, including capacity behind The Fidelis Partnership's new TFP PVT Consortium for war, terror and political violence risks. Business is originated and underwritten by The Fidelis Partnership, a separate privately held managing general agent, while Pelagos carries the balance sheet and pays commissions for the flow. The company listed on the NYSE in July 2023 as Fidelis Insurance Holdings; shareholders approved the rebrand at the April 28, 2026 annual meeting, the name changed effective May 11, 2026, and the shares began trading as PLGO on May 12, 2026.

RenaissanceRe Holdings, founded in 1993 and headquartered in Bermuda, is a global provider of property, casualty, and specialty reinsurance, with a historical reputation built on sophisticated property-catastrophe risk modeling. The company operates two reporting segments: Property (led by catastrophe excess-of-loss cover for hurricanes, earthquakes, and other perils) and Casualty and Specialty (lines such as directors-and-officers, professional liability, credit, cyber, marine, and aviation). Through its Capital Partners unit it also manages third-party joint ventures and funds, earning management and performance fees on capital it does not have to hold on its own balance sheet.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• PLGO drivers: A repaired combined ratio on a growing premium base; Buying back stock below book value.
• RNR drivers: Property-catastrophe pricing cycle; Third-party capital and fee income.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Catastrophe concentration is the defining risk: Q1 2025's ~115.6% combined ratio came from a single January wildfire event, and a hurricane season or a second large-loss quarter can wipe out a year of underwriting profit. For RNR, the dominant risk is catastrophe volatility: a single major hurricane, earthquake, or wildfire season can turn a strong year into a loss and erode book value quickly.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick PLGO if you believe its drivers more; RNR if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the PLGO and RNR guides.

PLGO. The valuation is the whole argument in both directions: ~6.8x trailing earnings and ~0.95x book are what the market pays for underwriting income it does not expect to recur evenly, and the ~$15.94 to ~$26.34 range over the past year shows how fast that view resets. Reported Q1 2026 figures are strong (~$108.0 million of net income, ~$1.15 per diluted share, annualized ROAE of ~18.6%), but a single quarter of a catastrophe book is not a trend. Q2 2026 results were scheduled for release on August 12, 2026, with a call on August 13, so the figures above describe the position going into that print, not after it.

RNR. RNR trades at a low single-digit to high single-digit trailing P/E and around one times book value, a valuation typical of catastrophe reinsurers whose earnings are lumpy and event-driven. Q1 2026 produced roughly a 22% annualized operating ROE, helped by about $160 million of favorable reserve development and strong fee and investment income. Because a heavy loss year can compress earnings sharply, investors often weigh tangible book value per share growth over time rather than any single quarter's multiple.

Headline figures (approximate, August 2026): PLGO shows revenue (ttm) ~$2.45 billion, net income (ttm) ~$376 million, q1 2026 combined ratio ~86.6% (vs ~115.6% in Q1 2025), book value per diluted share ~$26.22 at March 31, 2026; RNR shows market cap ~$13 billion, gross premiums written (annual) ~$12 billion, q1 2026 operating income (common) ~$591 million, q1 2026 net income (common) ~$285 million.

PLGO and RNR are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined PLGO and RNR exposure against your real portfolio. It is not an investment adviser.
