Item 1 Comment:
This Amendment No. 2 to Schedule 13D (this "Amendment") amends and supplements the previously filed statement on Schedule 13D filed on April 17, 2025, as amended and supplemented by Amendment No. 1 thereto filed on August 7, 2025 (and as may be further amended and supplemented from time to time, the "Schedule 13D"). Except as set forth below, all Items of the Schedule 13D remain unchanged. Capitalized terms used in this Amendment and not otherwise defined shall have the respective meanings assigned to such terms in the Schedule 13D. The information set forth in response to each separate Item below shall be deemed to be a response to all Items where such information is relevant. This Amendment is being filed to reflect the reduction of the percentage beneficially owned by each of the Reporting Persons below 5% solely as a result of the issuance of additional Shares by the Issuer. As disclosed in a Form 6-K filed with the U.S. Securities and Exchange Commission (the "SEC") by the Issuer on September 12, 2025 (the "Form 6-K"), on September 11, 2025, the Issuer entered into an underwriting agreement (the "Underwriting Agreement") relating to an underwritten public offering of 5,769,230 Shares. Pursuant to the Underwriting Agreement, the underwriter was granted a 45-day option to purchase up to an additional 865,285 Shares. As disclosed by the Issuer in the Form 6-K, on September 11, 2025, the underwriter partially exercised the option to purchase an additional 864,770 Shares. The Issuer announced the closing of the offering on September 15, 2025. As a result of this offering, the Issuer issued a total of 6,634,000 Shares. The Schedule 13D is hereby supplementally amended as follows: | ||
| Item 5. | Interest in Securities of the Issuer | |
| (a) | See items 7 through 13 on each cover page to this Amendment. Pani is controlled by Mr. Panagiotidis. Mr. Panagiotidis may be considered to be a beneficial owner of the Shares held by Pani by virtue of his control of the equity and voting power of Pani. As of September 15, 2025, the Shares held by the Reporting Persons represent approximately 4.59% of the outstanding Shares. Such percentage is calculated based on a total number of 12,628,731 Shares outstanding, calculated as the sum of (i) 5,994,731 Shares outstanding as of September 12, 2025, as disclosed by the Issuer in a prospectus supplement filed with the SEC by the Issuer on September 12, 2025 (the "Prospectus Supplement") to a registration statement on Form F-3 filed with the SEC by the Issuer on April 24, 2025 and subsequently declared effective by the SEC on April 28, 2025, and (ii) 6,634,000 Shares issued pursuant to the Underwriting Agreement. Pelagos Holdings Corp., an entity controlled by Mr. Panagiotidis, also owns 40,000 Series B Preferred Shares of the Issuer. Each Series B Preferred Share has the voting power of 100,000 Shares. To the best knowledge of the Reporting Persons, the Sole Director does not own any Shares. | |
| (b) | Item 5(a) of this Amendment is incorporated by reference into this Item 5(b). | |
| (c) | Except as described in Amendment No. 1 to Schedule 13D filed on August 7, 2025, the Reporting Persons, and to their knowledge, the Sole Director, have not effected any transactions in the Shares during the past 60 days. | |
| (d) | Not applicable. | |
| (e) | On September 15, 2025, the Reporting Persons ceased to be the beneficial owners of more than five percent (5%) of Shares. | |
| SIGNATURE | |
After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
