All statements, other than statements of historical facts, included or referenced in this presentation which address activities, events or developments which White Mountains expects or anticipates will or may occur in the future are forward-looking statements. The words “could”, “will,” “believe,” “intend,” “expect,” “anticipate,” “project,” “estimate,” “predict” and similar expressions are also intended to identify forward-looking statements.

These statements are based on certain assumptions and analyses made by White Mountains in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors believed to be appropriate in the circumstances. However, whether actual results and developments will conform to its expectations and predictions is subject to risks and uncertainties that could cause actual results to differ materially from expectations, including: (i) the risk factors set forth in our Form 10-K for the year ended December 31, 2022; (ii) claims arising from catastrophic events, such as hurricanes, windstorms, earthquakes, floods, wildfires, tornadoes, tsunamis, severe winter weather, public health crises, terrorist attacks, war and war-like actions, explosions, infrastructure failures, or cyber-attacks; (iii) recorded loss reserves subsequently proving to have been inadequate; (iv) the market value of White Mountains’s investment in MediaAlpha; (v) the trends and uncertainties from the COVID-19 pandemic, including the judicial interpretations on the extent of insurance coverage provided by insurers for COVID-19 pandemic-related claims; (vi) business opportunities (or lack thereof) that may be presented to it and pursued; (vii) actions taken by rating agencies, such as financial strength or credit ratings downgrades or placing ratings on negative watch; (viii) the continued availability of capital and financing; (ix) deterioration of general economic, market or business conditions, including due to outbreaks of contagious disease (including the COVID-19 pandemic) and corresponding mitigation efforts; (x) competitive forces, including the conduct of other insurers; (xi) changes in domestic or foreign laws or regulations, or their interpretation, applicable to White Mountains, its competitors or its customers; and (xii) other factors, most of which are beyond White Mountains’s control. Consequently, all of the forward-looking statements made in this presentation are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations. White Mountains assumes no obligation to publicly update any such forward-looking statements, whether as a result of new information, future events or otherwise.
