Exhibit 99.1 

COSTAMARE BULKERS HOLDINGS LIMITED REPORTS RESULTS FOR THE SECOND QUARTER AND SIX-MONTH PERIOD ENDED JUNE 30, 2026

Monaco, August 3, 2026 – Costamare Bulkers Holdings Limited (“Costamare Bulkers” or the “Company”) (NYSE: CMDB) today reported unaudited financial results for the second quarter and six-month period ended June 30, 2026.

Financial Highlights¹ and Operational Updates

¹ This earnings release focuses on the financial results and management’s discussion and analysis of Costamare Bulkers for the three-month and six-month periods ended June 30, 2026. Costamare Bulkers became an independent publicly traded company upon its spin-off from Costamare Inc. on May 6, 2025, prior to which it did not operate as a separate legal entity. Accordingly, the results for the three- and six-month periods ended June 30, 2026 are not comparable to the corresponding periods of 2025, and comparative figures for the three- and six-month periods ended June 30, 2025 are not presented.

² Adjusted Net Income and respective per share figures are non-GAAP measures and should not be used in isolation or as substitutes for Costamare Bulkers’ financial results presented in accordance with U.S. generally accepted accounting principles (“GAAP”). For the definition and reconciliation of these measures to the most directly comparable financial measure calculated and presented in accordance with GAAP, please refer to Exhibit I.

³ Liquidity includes Cash (as defined in footnote 4) and $84.7 million of available undrawn funds from one hunting license facility as of June 30, 2026.

⁴ Cash denotes Cash and cash equivalents (including restricted cash) of $234.8 million plus margin deposits of $12.0 million relating mainly to our forward freight agreements (“FFAs”) and bunker swaps.

⁵ Debt denotes Long-term debt including current and non-current portion.

⁶ As of July 31, 2026, and excluding one vessel sub-chartered out to Cargill on back to back terms pursuant to the Strategic Cooperation Agreement.

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

“During the second quarter of the year Costamare Bulkers generated an adjusted net income of $10 million.

We finalized the transfer of the Company’s entire legacy trading portfolio that was earmarked for Cargill, effectively reducing the risk on our balance sheet. We expect that our trading platform will be free of the three remaining legacy positions by year end.

As part of our fleet renewal program, we recently agreed to sell our 2009-built Supramax vessel, which is expected to be delivered within the third quarter.

With total cash exceeding debt by approximately $110 million, the Company is net cash positive, positioning us favorably to grow countercyclically should a low asset value environment arise.

Regarding the market, this quarter has been characterized by heightened volatility, particularly in the Capesize segment, largely driven by geopolitical uncertainty, energy market turbulence, and weather-related disruptions. Capesize rates peaked in late May before correcting by nearly $20,000/day through the end of June but have since held at robust levels.

The Panamax market remained supported by strong Capesize rates and the return of Chinese seaborne coal demand.

Unlike the larger vessel segments, the Supramax market was on a gradual upward trend throughout the period, supported by firmer grain and minor bulk volumes, as well as rising Liberian iron ore exports, which strengthened Atlantic market conditions.”

⁷ As of July 31, 2026.

Financial Summary

(1) Adjusted Net Income and Adjusted Earnings per Share are non-GAAP measures. Refer to the reconciliation of Net Income to Adjusted Net Income and Adjusted Earnings 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 period. 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) Adjusted Net Income and (ii) Adjusted Earnings per Share.

Exhibit I

Reconciliation of Net Income to Adjusted Net Income and Adjusted Earnings per Share

Adjusted Net Income and Adjusted Earnings per Share represent Net Income before deferred charter-in expense, amortization of time-charter assumed, non-recurring, non-cash write-off of loan deferred financing costs, non-recurring expenses for realignment of operating platform, general and administrative expenses - non-cash component and loss on derivative instruments, excluding realized (gain)/loss on derivative instruments. However, Adjusted Net Income and Adjusted Earnings per Share are not recognized measurements under U.S. GAAP. We believe that the presentation of Adjusted Net Income and Adjusted Earnings 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 and Adjusted Earnings per Share are useful in evaluating our ability to service additional debt and make capital expenditures. In addition, we believe that Adjusted Net Income and Adjusted Earnings 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 and Adjusted Earnings 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 and Adjusted Earnings 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 and Adjusted Earnings per Share should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. Previously, the Company’s calculation of Adjusted Net Income and Adjusted Earnings per Share included adjustments for any gain/loss incurred in connection with the sale of vessels and for any loss on vessels held for sale. As the Company’s fleet management activities may, subject to market and other conditions, periodically include the sale of dry bulk vessels, the Company no longer includes such adjustments in its calculation of these non-GAAP measures beginning with the results for the first quarter ended March 31, 2026. We believe this updated methodology provides a more meaningful view of the Company’s operating performance.

Exhibit II

Owned Dry Bulk Fleet Utilization⁽¹⁾

⁽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:
