Recent Company History

Over the past six months, White Mountains has combined earnings volatility with active capital deployment. Q4 2025 results on Feb 6, 2026 showed strong book value growth and were followed by a +2.75% move. In contrast, Q1 2026 results on May 6, 2026 highlighted a net loss and book value dip, with shares down 3.33%. Acquisition announcements in April and May 2026 produced small, mixed reactions, while a $131.3 million tender offer in late 2025 had little immediate impact. Today’s investor meeting notice fits into this pattern of generally modest news-driven price responses.

annual report on form 10-k regulatory

"The Company's 2025 Annual Report on Form 10-K, Notice of 2026 Annual..."

An annual report on Form 10‑K is a required, comprehensive filing that publicly traded companies give to regulators and investors summarizing their business, results of operations, detailed financial statements reviewed by independent auditors, material risks, legal issues and management’s discussion of performance. Investors use it like a company’s year‑end report card and medical checkup: it reveals how the business made money, where it is vulnerable, and the facts needed to compare value, judge risk and make informed investment decisions.

proxy statement regulatory

"Notice of 2026 Annual General Meeting of Members and Proxy Statement, and 2025..."

A proxy statement is a document companies send to shareholders ahead of a meeting that lays out the items up for a vote—like who will sit on the board, executive pay, and major corporate decisions—and provides background so shareholders can decide how to cast their votes or appoint someone to vote for them. Think of it as an agenda plus a ballot and briefing notes, important because the outcomes can change control, strategy, and value.

It’s like a TV broadcast but over the internet, allowing viewers from anywhere to tune in in real time or later.
