Berkshire Share Repurchase Agreement    
Berkshire share repurchase agreement
On April 30, 2024, the Company entered into an agreement (the share repurchase agreement) with Berkshire Hathaway Inc. on behalf of itself and its affiliates (collectively, Berkshire). Under the share repurchase agreement, at any time Berkshire beneficially owns at least 45.0% of the issued and outstanding common stock of the Company in the aggregate, the Company will repurchase from Berkshire, and Berkshire will sell to the Company, on a quarterly basis, a number of shares of common stock sufficient to return Berkshire’s aggregate beneficial ownership to 45.0% of the Company's issued and outstanding common stock. The per share price the Company will pay Berkshire for any such share repurchase will be the volume-weighted average price per share paid by the Company for any shares of common stock repurchased by the Company from public stockholders pursuant to the Company’s share repurchase program during the applicable repurchase period.
Under this agreement, repurchases of common stock by the Company from Berkshire will occur on the date that is two business days prior to the date of the Company’s regular quarterly or annual investor call to publicly report earnings; however, if at any time the Company determines that Berkshire beneficially owns or will beneficially own shares of common stock representing more than 49.5% of the issued and outstanding common stock in the aggregate, such determination will trigger immediate share repurchases under this agreement.
Pursuant to the April 30, 2024 share repurchase agreement with Berkshire Hathaway Inc. on behalf of itself and its affiliates, the Company had a repurchase obligation at December 31, 2025 to purchase shares from Berkshire for $199,940 in the aggregate, recorded as a payable and classified as due to related party on the Company's consolidated balance sheet. On January 29, 2026, the Company settled the Berkshire repurchase obligation in total for 1,658 shares of common stock for $199,940, at an average price paid of $120.56 per share.
Berkshire standstill agreement
Berkshire remains subject to a standstill agreement with the Company, as amended and restated as of February 9, 2022 (the standstill agreement). The standstill agreement currently restricts Berkshire’s actions with respect to acquiring additional shares of the Company’s common stock, and for any matter presented to Company stockholders, the standstill agreement requires Berkshire to vote any shares it beneficially holds in excess of 40% of the then-outstanding voting stock of the Company in accordance with the recommendation of the Board of Directors of the Company (Board). The standstill agreement also restricts Berkshire from taking certain actions, including, among other things, actions relating to stockholder proposals and actions seeking to control or influence the Board, management or policies of the Company. The standstill agreement provisions vary depending on Berkshire’s ownership levels and in the event of certain specified leadership changes at Berkshire.
The standstill agreement may be terminated by Berkshire at any time it ceases to beneficially own more than 15% of the Company's then-outstanding common stock, and terminates automatically if the Company enters into or publicly announces a plan to enter into a definitive agreement concerning a transaction involving all or a controlling portion of the Company's equity securities or all, or substantially all, of the Company's assets.
