The extension of the rights offering deadline reflects an administrative adjustment rather than a substantive change in financing terms or strategic intent. By moving the expiration from Wednesday, April 15 to Monday, April 20, 2026, the Company provides additional time for record holders—and particularly street-name holders requiring broker coordination—to complete exercises, including under the over-subscription privilege. The unchanged subscription price of $59.00 per share and fixed exchange ratio of five rights per share indicate no repricing or dilution recalibration. While the offering remains subject to standard conditions (e.g., timely receipt of funds and valid exercise notices), the filing does not disclose total shares offered, expected proceeds, or use of proceeds—limiting assessment of capital impact. Because the rights were distributed on March 30, 2026 and the offering is governed by a prospectus supplement filed the same day, investors should refer to that supplement for full terms, including eligibility, allocation mechanics, and potential proration. No forward-looking guidance, financial results, or material risk updates beyond those already filed in the March 26, 2026 Form 10-K are provided in this 8-K.
