White Mountains Insurance Group reported exceptionally strong financial results for the fourth quarter and full year 2025, highlighted by a significant increase in book value per share (BVPS). The 25% annual BVPS growth was primarily fueled by the successful sale of Bamboo, which generated a substantial net gain and added approximately $320 to BVPS. The company also demonstrated robust capital management through significant share repurchases in Q4, reducing outstanding shares and further enhancing shareholder value. The turnaround in comprehensive income from a loss to a substantial gain underscores the positive operational and strategic execution. With a healthy amount of undeployed capital, White Mountains maintains flexibility for future investments or shareholder returns, positioning it well for continued performance.
