(“Pavimar”), a related party controlled by Ismini Panagiotidis, the sister of the Company’s Chairman, Chief Executive Officer and Chief Financial Officer, Petros Panagiotidis, provided technical, crew and operational management services to the Company through the first half of 2022. With effect from July 1, 2022, Pavimar co-managed with Castor Ships the technical management of the Company’s dry bulk vessels, except for the M/V Magic Celeste, M/V Magic Ariel and M/V Magic Starlight, for which Castor Ships has provided the technical management since August 16, 2024, October 9, 2024 and December 18, 2024, respectively.

In addition, as of June 30, 2026, Castor had 74 majority-owned subsidiaries incorporated in Germany, two majority-owned subsidiaries incorporated in the Netherlands and one majority-owned subsidiary in each of Singapore, Colombia, Panama, and the People’s Republic of China.

During the six months ended June 30, 2026, 13 majority-owned subsidiaries that were previously consolidated by the Company were dissolved and, as a result, were removed from the scope of consolidation. The dissolutions were administrative in nature and did not result in any material cash payments, proceeds, or distributions to the Company. Additionally, no significant gains or losses were recognized in connection with these dissolutions, as the carrying amounts of the entities’ net assets were not material at the time of dissolution.
