A shareholder intends to sell up to 1,150,000 common shares through Goldman Sachs & Co. on or after 12 Aug 2025. The proposed block is valued at about $100.0 million and compares with 23,029,846 shares outstanding disclosed in the notice.

No sales were made during the past three months, and the filer certifies awareness of no undisclosed adverse information. Beyond the sale terms, the document contains no earnings or operational data.
