Welcome to our dedicated page for Costamare Bulkers Holdings SEC filings (Ticker: CMDB), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Costamare Bulkers Holdings Limited filings document the disclosure record of a foreign private issuer operating dry bulk vessels and the CBI dry bulk platform. Form 6-K reports furnish quarterly financial results, interim consolidated statements, predecessor carve-out financial statements, and press releases tied to Form 20-F annual reporting.
The filings also cover the company’s completed 2025 spin-off from Costamare Inc., NYSE-listed common stock, registration statement incorporation by reference, strategic cooperation materials, board appointments, a shareholders rights agreement amendment, and Series B high-vote, non-economic preferred stock used in voting-control and ownership-structure disclosures.
Costamare Bulkers Holdings Limited (NYSE: CMDB) disclosed a governance-focused transaction: it entered a Stock Subscription Agreement under which Konstantinos Konstantakopoulos will purchase 235 shares of a new, high‑vote, non‑economic Series B Preferred Stock for an aggregate $235.
Each preferred share carries 50,000 votes on all shareholder matters but has no dividend or distribution rights and only par value upon liquidation. The move was established in connection with a October 10, 2025 announcement by China’s Ministry of Transport regarding special port fees for U.S.-linked vessels. Following completion, the Konstantakopoulos family (none are U.S. persons) will control approximately 76.4% of the Company’s voting rights, up from about 65%, helping ensure U.S. persons cannot control over 25% of voting power.
The Series B is redeemable at the Company’s option—exercisable solely by the independent directors—at $1 per share, and all rights automatically terminate on the fifth anniversary of issuance. The Audit Committee of independent, disinterested directors reviewed and unanimously recommended approval.
Costamare Bulkers Holdings Limited reported that its board of directors appointed Mr. Dimitrios Sofianopoulos as a Class I director, effective October 2, 2025. He brings over 35 years of experience in the shipping sector and has worked with the Costamare group for the last 18 years. Mr. Sofianopoulos is qualified as both a Greek and UK lawyer and previously served as an equity partner at a major international law firm in New York, London, Monaco and Athens. Over his career, he has been involved in a wide range of shipping-related transactions, including mergers and acquisitions, IPOs, joint ventures, loan portfolios, commercial lending, leasing, fleet acquisitions and charter arrangements.
Costamare Bulkers Holdings Limited entered into a Strategic Cooperation Agreement with Cargill International S.A.. The company will transfer to Cargill the majority of its operating platform trading book, including most third-party chartered-in vessels, cargo transportation commitments and derivative positions, subject to counterparty consents. The net consideration for this transfer is expected to be immaterial to Costamare Bulkers.
The company believes this move will reduce its exposure to the volatile trading business and lead to more stable and predictable earnings while keeping its operating platform under Costamare Bulkers Inc. as a core part of its model. Costamare Bulkers and Cargill also plan broader cooperation in dry bulk, including bunker procurement, decarbonisation and vessel efficiency projects, and four additional Supramax time charters of owned vessels for four to six months.
After the transfer, a smaller book of third-party chartered-in vessels will remain under Costamare Bulkers Inc. Separately, Jens Jacobsen resigned as a director and Chief Commercial Officer of the company, and as a director of Costamare Bulkers Services ApS, on September 26, 2025.
