Item 3.

Source and Amount of Funds or Other Consideration.

All of the Shares reported herein were purchased on behalf of the Reporting Persons using their investment capital or funds under management. The aggregate purchase price of 1,419,461 Shares reported herein was approximately $38,499,925 (including brokerage commissions and transaction costs). The aggregate purchase price of the call options referencing 470,000 Shares reported herein was approximately $502,271. All such transactions were effected in the open market unless otherwise noted in Schedule A.

Item 4.

Purpose of Transaction.

The Reporting Persons purchased the securities of the Issuer based on the Reporting Persons’ belief that such securities, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of securities of the Issuer at prices that would make the purchase or sale of such securities desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons are concerned with the Issuer’s long-term underperformance and believe shareholder representation on the Board of Directors of the Issuer (the “Board”) is needed to drive improvements to the Issuer’s governance, capital allocation and operations. The Reporting Persons are engaging in discussions with the Board and management regarding the composition of the Board and opportunities to enhance shareholder value.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the securities of the Issuer, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management, the Board and their advisors, engaging in discussions with shareholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capitalization, the ownership structure, the structure, composition and skill sets of the Board and senior management or the operations of the Issuer, purchasing additional securities of the Issuer, selling some or all of such securities, entering into financial instruments or other agreements that increase or decrease the Reporting Persons’ economic or beneficial exposure with respect to their investment in the Issuer, engaging in short selling of or any hedging or similar transaction with respect to the securities of the Issuer, including swaps and other derivative instruments, or changing their intention with respect to any and all matters referred to in Item 4.

Item 5.

Interest in Securities of the Issuer.

(a) – (b) The responses of the Reporting Persons to rows 7, 8, 9, 10, 11 and 13 on the cover pages of this Schedule 13D are incorporated herein by reference. As of the date of this Schedule 13D, the Reporting Persons beneficially owned 1,889,461 Shares, including 470,000 Shares underlying certain call options, representing approximately 8.5% of the outstanding Shares. The percentage in this paragraph relating to beneficial ownership of Shares is based upon 22,214,000 Shares outstanding as of July 1, 2023 as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 8, 2023.

To the knowledge of each of the Reporting Persons, other than as set forth above, none of the persons named in Item 2 is the beneficial owner of any Shares.

(c)       Except as set forth in Schedule A, none of the Reporting Persons has effected any transactions in the securities of the Issuer during the past 60 days. A transaction in the securities of the Issuer during the past sixty days by a certain affiliate of the Reporting Persons, which no longer owns any Shares, is set forth in Schedule A and is incorporated herein by reference.

(d)       SCM is an investment adviser whose clients have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock to which this Schedule 13D relates. Other than as described in this Schedule 13D, no other person is known to the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock to which this Schedule 13D relates.

(e)       Not applicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

SCM is the investment adviser of its clients pursuant to investment management agreements or limited partnership agreements providing SCM the authority to, among other things, (i) invest the funds of such clients in the Shares; (ii) vote and dispose of the Shares; and (iii) file this Schedule 13D on behalf of such clients. Pursuant to such limited partnership agreements, the general partner of such clients is entitled to allocations based on assets under management and realized and unrealized gains. Pursuant to such investment management agreements, SCM (or SCMGP) is entitled to fees based on assets under management and realized and unrealized gains.

On August 25, 2023, the Reporting Persons entered into a Joint Filing Agreement in which the Reporting Persons agreed to the joint filing on behalf of each of them of statements on Schedule 13D with respect to securities of the Issuer, to the extent required by applicable law. The Joint Filing Agreement is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

SCP has purchased in the over-the-counter market American-style call options referencing an aggregate of 470,000 Shares, which have a strike price of $25.00 and expire on September 15, 2023.
