(1) The shares of common stock will be offered for resale by the selling stockholders named herein pursuant to the prospectus contained herein. Pursuant to Rule 416 under the Securities Act of 1933, as amended (the “Securities Act”), this registration statement also covers such additional number of shares of common stock issuable upon stock splits, stock dividends, reclassifications, recapitalizations, combinations or similar events, with respect to the shares of common stock being registered pursuant to this registration statement.

(2) Estimated solely for the purpose of calculating the amount of the registration fee in accordance with Rule 457(c) under the Securities Act. The proposed maximum offering price per share and proposed maximum aggregate offering price are based upon the average of the high and low sales prices of the registrant’s common stock on May 1, 2024, as reported on the New York Stock Exchange.

(3) Pursuant to Rule 415(a)(6) under the Securities Act, (a) 73,530 shares of common stock included in this registration statement are unsold securities previously registered under a registration statement on Form S-3 (Registration No. 333-255772) filed by the registrant on May 5, 2021 (the “2021 Registration Statement”) (as to which shares a filing fee of $663.75 was previously paid), (b) 219,572 shares of common stock issuable upon exercise of a warrant included in this registration statement are unsold securities previously registered under the 2021 Registration Statement (as to which shares a filing fee of $1,982.06 was previously paid) and (c) 280,428 shares of common stock issuable upon exercise of a warrant included in this registration statement are unsold securities previously registered under a post-effective

amendment to the 2021 Registration Statement filed on June 9, 2021 (as to which shares a filing fee of $1,994.17 was previously paid). Accordingly, an aggregate of $4,639.98 in filing fees was previously paid in connection with such unsold shares and will continue to be applied to such unsold shares pursuant to Rule 415(a)(6). All 573,530 of those unsold shares of common stock (and associated filing fees) are being carried forward and registered under this registration statement. The filing fee of $64.62 being paid herewith relates to the 10,287 shares of common stock issuable upon exercise of a warrant newly registered under this registration statement. Pursuant to Rule 415(a)(6), the offering of the unsold securities registered under the 2021 Registration Statement will be deemed terminated as of the date of effectiveness of this registration statement.
