The headline result was well ahead of the published earnings bar, but book value is the more useful measure here. Reported diluted EPS was $80.58 versus a published consensus near $27, though the gap was driven heavily by mark-to-market investment gains rather than recurring operating earnings. Book value per share rose 4.1% sequentially to $2,257.60, including dividends, after falling 0.8% in the first quarter (Book value per share table).

|---|---|---|---|
| Book value per share | $2,257.60 | $2,169.66 at Mar. 31, 2026 | Up 4.1% quarter over quarter (Book value per share table) |
| Diluted EPS | $80.58 | $47.75 | Boosted by investment gains (EPS table) |
| Comprehensive income to common shareholders | $199.4 million | $123.7 million | Higher year over year (Comprehensive income statement) |
| Ark combined ratio | 83.9% | 84.4% | Slightly better underwriting (Ark/WM Outrigger insurance ratios) |
| MediaAlpha gain | $58.4 million | $30.5 million | Major contributor to quarterly gains (Other Operations results) |
| Share repurchases | $191 million | — | Bought shares at 93% of quarter-end book value (Capital allocation disclosure) |
Ark delivered the cleanest operating improvement. Its combined ratio improved to 84.0% from 85.2%, despite $17 million of Iran-war losses, while net earned premiums rose to $375 million from $357 million (Ark segment results; Ark/WM Outrigger insurance ratios). The improvement is credible, but gross written premiums fell 5% as property-market pricing softened, so growth is no longer an unqualified tailwind (Ark segment results).
A large share of the earnings beat came from valuation-sensitive gains. MediaAlpha contributed a $58 million unrealized gain as its share price rose 35% during the quarter, while Kudu recorded $50 million of investment gains tied largely to lower discount rates and valuation step-ups from sale transactions (Other Operations results; Kudu results). Those gains lifted reported earnings and book value, but they are less repeatable than underwriting income; excluding MediaAlpha, the investment portfolio still returned a respectable 2.8%, but equity returns lagged the S&P 500's 15.2% quarterly gain (Portfolio return disclosure).
The rest of the portfolio was uneven, limiting the read to mildly positive rather than a broad operating beat. HG Global's gross pricing fell to 135 basis points from 206 basis points and pre-tax income declined to $10 million from $17 million, while Distinguished remained loss-making with a $10.5 million quarterly pre-tax loss despite improving managed premiums and ScaleCo adjusted EBITDA (HG Global results; Distinguished results). WTM Partners added $9 million of adjusted EBITDA and two acquisitions, but that contribution is still small relative to the investment-driven gains (WTM Partners results).
Capital allocation strengthened the quarter's message. White Mountains repurchased $191 million of stock at 93% of reported book value and received $90 million from HG Global's refinancing-related dividend, leaving roughly $0.8 billion of undeployed capital (Capital allocation disclosure; HG Global results). Net versus expectations: a clear reported earnings beat and a solid book-value quarter, supported by genuinely strong Ark execution and buybacks, but with enough reliance on MediaAlpha and fair-value gains—and weaker HG pricing—to keep the improvement from reading as a broad-based recurring earnings breakout.
