Exhibit 99.1

COSTAMARE BULKERS HOLDINGS LIMITED REPORTS RESULTS FOR THE
THIRD QUARTER AND NINE-MONTH PERIOD ENDED SEPTEMBER 30, 2025

Monaco, November 14, 2025 – Costamare Bulkers Holdings Limited (“Costamare Bulkers” or the “Company”) (NYSE: CMDB) today reported unaudited financial results for the third quarter and nine-month period ended September 30, 2025.

This earnings release focuses on the financial results and management’s discussion and analysis for the three-month period ended September 30, 2025, reflecting the Company’s performance during its first full quarter as an independent, publicly traded company.

Costamare Bulkers had no operating activity during the nine-month period ended September 30, 2024 and remained a wholly-owned subsidiary of Costamare Inc. (“Costamare”), a New York Stock Exchange (the “NYSE”) listed company, until May 6, 2025, when it became an independent, publicly traded company on NYSE through a spin-off from Costamare.

Costamare Bulkers had nominal operations from January 1, 2025 until late March 2025, when Costamare transferred to it the entities engaged in the dry bulk business, which own, have owned, or were formed with the intention to own dry bulk vessels. The results of these entities are included in Costamare Bulkers’ consolidated statement of operations for the three- and nine- month period ended September 30, 2025. On May 6, 2025, Costamare Bulkers also acquired from Costamare and a minority shareholder Costamare Bulkers Inc. (“CBI”), a dry bulk operating platform, whose results are included from that date forward. No comparative figures are presented for the three- and nine- month period ended September 30, 2024, as Costamare Bulkers had no operations during that time and all amounts would have been nil.

REALIGNMENT OF TRADING PLATFORM AND INTEGRATION WITH OWNED FLEET

Entered into a Strategic Cooperation Agreement (the “Cooperation Agreement”) with Cargill International S.A. (“Cargill”) (announced on September 29, 2025), which included among other things:

The transfer of the majority of CMDB’s trading book as of that date, including:

Chartered-in vessels;

Cargo transportation commitments (contracts of affreightment); and

Derivatives positions.

The charter-out of four Company-owned Supramax vessels for a period of four to six months.

The above-mentioned transfers are currently in progress with the timing for completion dependent on, among other things, the agreement of third parties and the vessels operations’ schedule.

As of November 13, 2025, the following transfers have been effected or have been agreed to become effected:

Novation or sub-charter to Cargill⁶ of 19 chartered-in vessels;

Novation or relet to Cargill⁷ of the entire forward cargo book under the Cooperation Agreement; and

Transfer of the entire FFA trading book under the Cooperation Agreement.

In addition to the Cooperation Agreement, we have:

Early-redelivered three chartered-in vessels.

Chartered-out on long-term period two chartered-in vessels.

The remaining chartered-in fleet consists of 12⁸ third-party owned dry bulk vessels of which:

8 vessels are expected to be redelivered within Q4 2025/Q1 2026.

4 vessels are expected to be redelivered within Q2 2026/Q4 2026.

The realigned trading platform will aim to:

focus on Kamsarmax-type vessels by building a balanced cargo-driven portfolio that optimizes earnings and manages downside exposure while maintaining flexibility through market cycles, and

support the owned fleet through improved market insight and operational flexibility.

III.

OWNED FLEET

Costamare Bulkers currently owns a fleet of 31⁹ dry bulk vessels of a total capacity of approximately 2.8 million DWT, consisting of:

7 Capesize vessels out of which 6 are on period charters.

7 Kamsarmax vessels out of which 5 are on period charters.

8 Ultramax vessels all of which are on period charters.

9 Supramax vessels out of which 7 are on period charters.

The majority of the period charters are on index-linked charter agreements with owner’s option to convert to fixed rate based on the prevailing FFA curve.

______________________________

⁶ On back-to-back terms with the original charterparties.

⁷ On back-to-back terms with the original agreements.

⁸ As of November 13, 2025 and excluding vessels agreed to be novated or sub-chartered on back-to-back terms pursuant to the Cooperation Agreement.

⁹ As of November 13, 2025.

IV.

DEBT FINANCING

Financed the acquisition of the Imperator through an existing hunting license facility. Total amount drawn of approximately $15.3 million.

Approximately $84.7 million is available through one hunting license facility for the financing of vessels acquisitions until December 2027.

No significant loan maturities until 2029.

Mr. Gregory Zikos, Chief Executive Officer of Costamare Bulkers Holdings Limited, commented:

“This is the first full quarter, during which the Company reports financial results as an independent, publicly traded entity.

During the quarter Costamare Bulkers generated net income of $7.4 million. With total cash of about $206 million and debt of ca. $160 million, the Company is in a net debt negative position, owning a fleet of 31 dry bulk vessels with an average age of approximately 13 years and an average size of ca. 91,700 DWT.

As previously announced, in September we entered into a Strategic Cooperation Agreement with Cargill whereby, among other things, we agreed to gradually transfer to Cargill the majority of our trading book. We have effectively transferred our entire forward cargo book and FFA positions, as well as the majority of the chartered-in vessels. We intend to maintain our operating platform as an integral part of our business mainly focusing on Kamsarmaxes with the goal to optimize earnings and tightly manage downside exposure.

We are progressing on our strategy to divest older and smaller tonnage and replacing it with younger and bigger-sized vessels. During the quarter we concluded the disposals of five Handysize ships and one Supramax vessel and we accepted delivery of one Capesize.

Regarding the market, the Capesize index retreated from late July by the end of August due to excess tonnage and softer Brazil flows, before rebounding in late September on the back of end-of-quarter Australia iron ore and Pacific weather disruptions. In October, China’s plan to impose reciprocal port restrictions on US-linked vessels triggered a brief spike in FFAs despite limited physical market impact. However, following the 30 October US–China meeting, the measures were suspended for a year under a trade de-escalation framework, leading Capes FFAs to ease. Panamax rates were lifted as well during October; however as measures were suspended they have since retreated.”

Financial Summary

(Expressed in thousands of U.S. dollars, except share and per share data)	Nine-month period ended September 30, 2025			Three-month period ended September 30, 2025

Voyage revenue	$	265,979		$	158,768
Voyage revenue – related parties	$	112,761		$	64,106
Total voyage revenue	$	378,740		$	222,874
Accrued charter revenue (1)	$	2		$	1
Total voyage revenue adjusted on a cash basis (2)	$	378,742		$	222,875
Adjusted Net Income / (Loss) (3)	$	(10,423	)	$	5,361
Weighted Average number of shares		13,754,628			24,241,640
Adjusted Earnings / (Losses) per share (3)	$	(0.76	)	$	0.22
Net Income / (Loss)	$	(19,161	)	$	7,354
Weighted Average number of shares		13,754,628			24,241,640
Earnings / (Losses) per share	$	(1.39	)	$	0.30

(1) Accrued charter revenue represents the difference between cash received during the period and revenue recognized during the period on a straight-line basis at the charter’s average rate. In the early years of a charter with escalating charter rates, voyage revenue will exceed cash received during the period and during the last years of such charter cash received will exceed revenue recognized on a straight-line basis. The reverse is true for charters with descending rates.

(2) Total voyage revenue adjusted on a cash basis represents Total voyage revenue after adjusting for non-cash “Accrued charter revenue” recorded under charters with escalating or descending charter rates. However, Total voyage revenue adjusted on a cash basis is not a recognized measurement under U.S. GAAP. We believe that the presentation of Total voyage revenue adjusted on a cash basis is useful to investors because it presents the charter revenue for the relevant period based on the then-current daily charter rates.

(3) Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share are non-GAAP measures. Refer to the reconciliation of Net Income / (Loss) to Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share.

Non-GAAP Measures

The Company reports its financial results in accordance with U.S. GAAP. However, management believes that certain non-GAAP financial measures used in managing the business may provide users of these financial measures additional meaningful comparisons between current results and results in prior operating periods. Management believes that these non-GAAP financial measures can provide additional meaningful reflection of underlying trends of the business because they provide a comparison of historical information that excludes certain items that impact the overall comparability. Management also uses these non-GAAP financial measures in making financial, operating and planning decisions and in evaluating the Company’s performance. The tables below set out supplemental financial data and corresponding reconciliations to GAAP financial measures for the relevant periods. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, voyage revenue, net income, or other measures determined in accordance with GAAP. Non-GAAP financial measures include (i) Voyage revenue adjusted on a cash basis (reconciled above), (ii) Adjusted Net Income / (Loss) and (iii) Adjusted Earnings / (Losses) per Share.

Exhibit I

Reconciliation of Net Income / (Loss) to Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share

	Nine-month period ended September 30,			Three-month period ended September 30,
(Expressed in thousands of U.S. dollars, except share and per share data)	2025			2025
Net Income / (Loss)	$	(19,161	)	$	7,354
Accrued charter revenue		2			1
Deferred charter-in expense		145			91
General and administrative expenses - non-cash component		1,192			869
Loss on sale of vessels		10,399			3,830
Loss on vessel held for sale		1,058			1,058
Non-recurring, non-cash write-off of loan deferred financing costs		274			157
Gain on derivative instruments, excluding realized (gain) / loss on derivative instruments (1)		(4,332	)		(7,999	)
Adjusted Net Income / (Loss)	$	(10,423	)	$	5,361
Adjusted Earnings / (Losses) per Share	$	(0.76	)	$	0.22
Weighted average number of shares		13,754,628			24,241,640

Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share represent Net Income / (Loss) before non-cash “Accrued charter revenue” recorded under charters with escalating or descending charter rates, deferred charter-in expense, loss on vessel held for sale, loss on sale of vessels, non-recurring, non-cash write-off of loan deferred financing costs, general and administrative expenses - non-cash component and gain on derivative instruments, excluding realized (gain)/loss on derivative instruments. “Accrued charter revenue” is attributed to the timing difference between the revenue recognition and the cash collection. However, Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share are not recognized measurements under U.S. GAAP. We believe that the presentation of Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share are useful to investors because they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. We also believe that Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share are useful in evaluating our ability to service additional debt and make capital expenditures. In addition, we believe that Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share are useful in evaluating our operating performance and liquidity position compared to that of other companies in our industry because the calculation of Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share generally eliminates the effects of the accounting effects of certain hedging instruments and other accounting treatments, items which may vary for different companies for reasons unrelated to overall operating performance and liquidity. In evaluating Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of Adjusted Net Income / (Loss) and Adjusted Earnings / (Losses) per Share should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

(1)

Items to consider for comparability, when prior period figures are presented, include gains and charges. Gains positively impacting Net Income / (Loss) are reflected as deductions to Adjusted Net Income / (Loss). Charges negatively impacting Net Income / (Loss) are reflected as increases to Adjusted Net Income / (Loss).

Owned Dry Bulk Fleet Utilization⁽¹⁾

	Nine-month period ended September 30,			Three-month period ended September 30,
	2025			2025
Owned Dry Bulk Fleet Available Days ^(*)		6,535			3,259
Owned Dry Bulk Fleet Utilization^(*)		98.1	%		98.4	%

^(*) Since late March 2025, when Costamare transferred to Costamare Bulkers the entities engaged in the dry bulk business.

⁽¹⁾ We calculate utilization of our owned dry bulk fleet (including vessels chartered-in by CBI) by dividing (i) the aggregate number of our on-hire days and ballast days (excluding dry dock ballast days) in a period of our owned dry bulk fleet by (ii) the number of our available days (owned dry bulk fleet) during such period. We use the following definitions in our calculation of utilization of owned dry bulk fleet:

On-hire days. We define on-hire days as the total days that a vessel was on-hire during a period.

Ballast days (excluding dry dock ballast days). We define ballast days (excluding dry dock ballast days) during a period, as the total number of days that a vessel is not on-hire, but is conducting ordinary ship operations (other than dry dock ballast days) which includes repositioning from a discharging port to a loading port, sailing to a port for the conclusion of a prospective sale of a vessel or a change of the technical manager of a vessel.

Available days. We define available days as the number of our ownership days of our owned dry bulk fleet during a period less the aggregate number of dry dock days and dry dock ballast days during such period. We use the following definitions in our calculation of available days (owned dry bulk fleet):

Dry dock days. We define dry dock days as the days during a period that a vessel underwent scheduled repairs or repairs under guarantee, vessel upgrades, scheduled dry-docking or special surveys.

Dry dock ballast days. We define dry dock ballast days as the total days during a period that a vessel spends sailing to and from a shipyard for scheduled repairs or repairs under guarantee, vessel upgrades, scheduled dry-docking or special surveys.
