If our stockholders approve this Proposal, and the Board elects to effect the Reverse Stock Split, we will effect the Reverse Stock Split by filing the Reverse Stock Split Amendment with the Secretary of State of the State of Delaware. The Reverse Stock Split will become effective, and the combination of, and reduction in, the number of our outstanding shares as a result of the Reverse Stock Split will occur automatically, at the effective time set forth in the Reverse Stock Split Amendment, without any action on the part of our stockholders and without regard to the date that stock certificates representing any certificated shares prior to the Reverse Stock Split are physically surrendered for new stock certificates. Beginning at the effective time of the Reverse Stock Split, each certificate representing pre-reverse stock split shares will be deemed for all corporate purposes to evidence ownership of post-reverse stock split shares. The text of the Reverse Stock Split Amendment is subject to modification to include such changes as may be required by the office of the Secretary of State of the State of Delaware and as the Board deems necessary and advisable to effect the Reverse Stock Split.

The Board reserves the right, notwithstanding stockholder approval and without further action by the stockholders, to elect not to proceed with the Reverse Stock Split if, at any time prior to filing the Reverse Stock Split Amendment, the Board, in its sole discretion, determines that it is no longer in the best interests of the Company and its stockholders to proceed with the Reverse Stock Split. By voting in favor of the Reverse Stock Split, you are expressly also authorizing the Board to delay (until May 31, 2025) or abandon the Reverse Stock Split. If the Reverse

Stock Split Amendment has not been filed with the Secretary of State of the State of Delaware by the close of business on May 31, 2025, the Board will abandon the Reverse Stock Split .

Certain U.S. Federal Income Tax Consequences of the Reverse Stock Split

The following discussion is a summary of certain tax consequences of the Reverse Stock Split. It addresses only stockholders who hold our common stock as capital assets for U.S. federal income tax purposes (generally, property held for investment). This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder, administrative rulings and judicial decisions as of the date hereof, all of which may change, possibly with retroactive effect, resulting in U.S. federal income tax consequences that may differ from those discussed below. It does not purport to be complete and does not address tax considerations under state, local, non-U.S. and other laws nor does it address stockholders subject to special rules, such as financial institutions, tax-exempt organizations, insurance companies, dealers in securities, foreign stockholders, stockholders who hold their pre-Reverse Stock Split shares as part of a straddle, hedge or conversion transaction, and stockholders who acquired their pre-Reverse Stock Split shares pursuant to the exercise of employee stock options or otherwise as compensation. We have not sought, and will not seek, an opinion of counsel or a ruling from the Internal Revenue Service (“IRS”) regarding the U.S. federal income tax consequences of the Reverse Stock Split and there can be no assurance that the IRS will not challenge the statements and conclusions set forth below or a court would not sustain any such challenge. The tax treatment of a stockholder may vary depending upon the particular facts and circumstances of such stockholder. Each stockholder is urged to consult with such stockholder’s own tax advisor with respect to the tax consequences of the Reverse Stock Split.

The Reverse Stock Split is intended to constitute a reorganization within the meaning of Section 368 of the Code. Assuming the Reverse Stock Split qualifies as reorganization, a stockholder generally will not recognize gain or loss on the Reverse Stock Split, except to the extent of cash, if any, received in lieu of a fractional share interest. The aggregate tax basis of the post-Reverse Stock Split shares received will be equal to the aggregate tax basis of the pre-Reverse Stock Split shares exchanged therefor (excluding any portion of the stockholder’s basis allocated to fractional shares), and the holding period of the post-Reverse Stock Split shares received will include the holding period of the pre-Reverse Stock Split shares exchanged. Treasury regulations promulgated under the Code provide detailed rules for allocating the tax basis and holding period of the shares of our common stock surrendered to the shares of our common stock received pursuant to the Reverse Stock Split. Stockholders holding shares of our common stock acquired on different dates and at different prices should consult their tax advisors regarding the allocation of the tax basis and holding period of such common stock.

A stockholder of the pre-Reverse Stock Split shares who receives cash in lieu of fractional shares will generally be treated as having exchanged a fractional share interest for cash in a redemption by us. The amount of any gain or loss will be equal to the difference between the portion of the tax basis of the pre-Reverse Stock Split shares allocated to the fractional share interest and the cash received and generally should be capital gain or loss and generally would be a long-term gain or loss to the extent that the stockholder’s holding period exceeds 12 months.
