The Offering was made pursuant to a shelf registration statement on Form S-3 (Registration File No. 333- 282778), which was filed with the U.S. Securities and Exchange Commission (the “Commission”) on October 22, 2024, and amended by Amendment No. 1 thereto, which was filed with the Commission on October 31, 2024, and became effective on November 4, 2024, and the related base prospectus included in the Registration Statement, as supplemented by the prospectus supplement dated June 24, 2025.

The Offering closed on June 25, 2025. The Company intends to use the net proceeds from the Offering for general corporate purposes, which may include among other things, capital expenditures and working capital.
