Share Repurchase Program
Our board of directors has authorized a share repurchase program (the "Share Repurchase Program") under which we may purchase up to $600.0 million of our outstanding Common Shares. The Share Repurchase Program does not have a fixed expiration, may be modified, suspended or discontinued at any time and any repurchases made pursuant to the Share Repurchase Program are subject to compliance with applicable covenants and restrictions under our financing agreements and the Business Combination Agreement.
There were no share repurchases during each of the three and six months ended June 30, 2026 and 2025. As of June 30, 2026, we had approximately $175.0 million available for share repurchases pursuant to the Share Repurchase Program.
