#### ABOUT THIS PROSPECTUS SUPPLEMENT

This Prospectus Supplement No. 2 is being filed to amend and supplement information that appears under the caption "Selling Shareholders" in the Prospectus. Capitalized terms that are not defined in this Prospectus Supplement No. 2 are defined in the Prospectus.

#### SELLING SHAREHOLDERS

The following information is being provided to update the Selling Shareholders table in the Prospectus to reflect various estate planning transfers and prior sales under the Prospectus.

The following table sets forth information as of February 10, 2026 with respect to the number of shares of our Common Stock beneficially owned by each selling shareholder prior to this offering, the number of shares that may be offered for sale by each selling shareholder by the Prospectus and the number of shares that each selling shareholder would have following the sale of all of the shares of Common Stock offered by the selling shareholders under the Prospectus. Only those selling shareholders listed below, or their donees, pledgees, transferees, or successors-in-interest, may offer and sell the Common Stock pursuant to the Prospectus. The selling shareholders may offer for sale pursuant to the Prospectus from time to time none, some or all of the shares of our Common Stock listed below. Accordingly, the numbers of shares shown in the following table as beneficially owned after the offering are only estimates, based on the assumption that all of the shares offered by the selling shareholders under the Prospectus will be sold. In the past three years, none of the selling shareholders has had any material relationship with the Company or any of its predecessors or affiliates.

The percentage ownership data is based on 22,657,421 shares of Common Stock outstanding as of October 31, 2025.

The Company has prepared the table below based on information given to the Company by, or on behalf of, the selling shareholders on or before the date of Prospectus Supplement No. 2.
