Sale of Neo-Panamax 13,696 TEU container vessel M/V Buenaventura Express

On October 29, 2025, Capital Clean Energy Carriers Corp. (the “Company” or “CCEC”) signed a memorandum of agreement with a third party for the sale of the M/V Buenaventura Express (142,411 DWT / 13,696 TEU, hybrid scrubber-fitted, eco container vessel, built 2023, Hyundai Samho Industries Co. Ltd, South Korea). The vessel was delivered to its new owners on January 19, 2026, and we recognized a total book gain from the sale of $4.2 million. Cash proceeds were used to pay down outstanding debt of $84.4 million and for general corporate purposes. The divestment of this additional container vessel is consistent with the Company’s stated strategy to shift our strategic focus towards the transportation of various forms of gas to industrial customers, including liquefied natural gas (“LNG”) and emerging new commodities in connection with the energy transition. Since February 2024, CCEC has sold 14 container vessels generating gross proceeds of approximately $814.3 million. Following this sale, the Company retains only one 13,312 TEU container vessel in its fleet, which is on long-term time charter through 2033, with options to extend up to 2039.

Order for three latest specification liquefied natural gas carriers to be delivered in 2028 and 2029

On December 29, 2025, the Company announced it has ordered three latest technology LNG carriers (“LNG/Cs”) to be built at HD Hyundai Samho Co., Ltd in South Korea, scheduled for delivery in 2028 and 2029. Specifically, one vessel is scheduled for delivery in the third quarter of 2028 and two further deliveries are scheduled in the first quarter of 2029. The en-bloc ship building price of these vessels is $769.5 million.

With its latest order for three additional LNG/Cs, the Company has 12 LNG/Cs currently in the water and nine LNG/Cs on order (“Newbuild LNG/Cs”). In addition, CCEC has on order an additional nine gas carriers, including three handy liquid CO₂(“LCO₂”)/multi-gas carriers and six dual-fuel medium gas carriers (the “Gas Fleet”), with deliveries starting in the second quarter of 2026.

Delivery of 22,000 cubic meter low-pressure liquid CO₂ carrier LCO₂ Active

On January 6, 2026, the Company announced the delivery of the world’s first 22,000 cubic meters (“cbm”) low-pressure LCO₂ carrier, the LCO₂ Active, from Hyundai Mipo Dockyard Co., Ltd. (“HMD”). The LCO₂ Active is the first of four 22,000 cbm LCO₂/multi gas carriers under CCEC’s investment program at HMD. The vessel is designed to transport LCO₂, while remaining fully competitive in the conventional handy semi-refrigerated gas carrier market, as these ships feature multi-cargo capability and can carry LCO₂, liquefied petroleum gas (“LPG”), ammonia and selected petrochemicals.

The LCO₂ Active commenced a six-month time charter transporting LPG for an energy trading company, with an option to extend the charter for an additional six months.

The acquisition of the LCO₂ Active was financed with $29.4 million of cash on hand and a 12-year export credit agency-backed loan of $48.9 million. The loan is repayable in 48 quarterly instalments of $0.6 million, with a balloon payment of $18.0 million payable with the final instalment in January 2033. The Company may borrow an additional amount of up to $7.5 million if the vessel secures longer term employment.

As a result of the Company’s contracting for the three additional LNG/Cs and the delivery of the LCO₂ Active, the Company’s capital expenditure schedule (“CAPEX”) has been revised as follows:
