Management Commentary for Second Quarter 2025:

Mr. Petros Panagiotidis, Chief Executive Officer of Castor, commented:

“Amid ongoing market headwinds in the dry bulk sector during the second quarter of 2025, we advanced our fleet renewal strategy through the sale of older vessels, further enhancing efficiency and overall quality.

While near-term market conditions remain challenging, we are confident in the sector’s long-term fundamentals and in our ability to capture future opportunities.

Backed by a solid balance sheet, the strength and strategic flexibility of our business model, reinforces our belief that disciplined capital deployment and portfolio renewal can deliver value.”

Earnings Commentary:

Second Quarter ended June 30, 2025, and 2024, Results

Total vessel revenues for the three months ended June 30, 2025, decreased to $10.2 million from $16.3 million in the same period of 2024. This variation was mainly driven by (i) the decrease in our Available Days (defined below), from 1,076 days in the three months ended June 30, 2024 to 825 days in the three months ended June 30, 2025, representing a 23.3% decrease, following the sale of one dry bulk vessel and one container vessel in the second quarter of 2025, as partially offset by the acquisitions of the M/V Magic Celeste on August 16, 2024, M/V Raphaela on October 3, 2024 and M/V Magic Ariel on October 9, 2024, and (ii) the decrease in prevailing charter rates of our dry bulk vessels.

Revenue from services for the three months ended June 30, 2025, amounted to $7.8 million and relates to revenue earned from our subsidiary acquired in late 2024, MPC Münchmeyer Petersen Capital AG (“MPC Capital”). Revenue from services is generated through the following streams: (i) transaction services, (ii) management services for companies and assets, and (iii) ship management services.

There was a decrease in voyage expenses to $0.7 million in the three months ended June 30, 2025, from $1.0 million in the same period of 2024, which was mainly associated with the decrease in brokerage commissions to third parties mainly due to the decrease of the revenue of our fleet, partially offset by increased port and other expenses, brokerage commissions to related party and the loss on bunkers.

Vessel operating expenses decreased by $1.9 million to $4.6 million in the three months ended June 30, 2025, from $6.5 million in the same period of 2024, mainly reflecting the decrease in the Ownership Days of our fleet to 883 days in the three months ended June 30, 2025, from 1,076 days in the same period in 2024.

Cost of revenue from services for the three months ended June 30, 2025 amounted to $5.8 million and relates to expenses for purchased services from third party providers and employee expenses from our subsidiary, MPC Capital.

Management fees in the three months ended June 30, 2025 amounted to $1.0 million, whereas in the same period of 2024, management fees totaled $1.1 million. This decrease in management fees is due to the net decrease in the total number of Ownership Days for which our managers charge us a daily management fee following the sales and acquisitions of vessels mentioned above, partly offset by a management fee adjustment for inflation under our Amended and Restated Master Management Agreement with effect from July 1, 2024.

Depreciation and amortization expenses are comprised of vessels’ depreciation, the amortization of vessels’ capitalized dry-dock costs, property and equipment depreciation and intangible assets amortization. Depreciation expenses decreased to $2.3 million in the three months ended June 30, 2025, from $3.1 million in the same period of 2024. The decrease by $0.8 million reflects mainly the net decrease in the Ownership Days of our fleet following the sales and acquisitions of vessels discussed above. Dry-dock and special survey amortization charges amounted to $0.3 million for the three months ended June 30, 2025, compared to a charge of $0.4 million in the respective period of 2024. This variation in dry-dock amortization charges primarily resulted from the decrease in aggregate amortization days, mainly as a result of the sale of vessels mentioned above as partially offset by the amortization related to the vessels M/V Magic Starlight and M/V Magic Ariel, which initiated and completed their scheduled dry-dock during the second quarter ended June 30, 2025. Further to the above, depreciation and amortization expenses for our asset management segment amounted to $0.5 million for the three-month period ended June 30, 2025, comprising property and equipment depreciation and intangible assets amortization.

General and administrative expenses in the three months ended June 30, 2025, amounted to $5.4 million, whereas, in the same period of 2024, general and administrative expenses totaled $1.5 million. This increase mainly reflects the increase in professional fees and other expenses, audit fees and personnel expenses following the acquisition of MPC Capital.

Net gain/(loss) on sale of vessels in the three months ended June 30, 2025, amounted to $0.1 million following the sales of the: (i) M/V Gabriela A on May 7, 2025 and (ii) M/V Magic Callisto on April 28, 2025. Gain on sale of vessels in the three months ended June 30, 2024, amounted to $11.4 million following the sales of the: (i) M/V Magic Nebula on April 18, 2024, (ii) M/V Magic Venus on May 10, 2024, (iii) M/V Magic Vela on May 23, 2024, and (iv) M/V Magic Horizon on May 28, 2024.

Net gain on disposal of assets in the three months ended June 30, 2025, amounted to $0.4 million following the sale of an asset management contract.

Net loss from equity method investments in the three months ended June 30, 2025 and 2024, amounted to $0.1 million and $0, respectively, representing our share in jointly owned companies or equity method investments (all of which relate to the asset management segment).

Net gain from equity method investments measured at fair value in the three months ended June 30, 2025 and 2024, amounted to $1.6 million and $0, respectively, resulting from the revaluation of such investments. These represent our share in MPC Container Ships ASA (“MPCC”) and MPC Energy Solutions N.V for which we have elected the fair value option.

During the three months ended June 30, 2025, we incurred net interest and finance costs of $0.9 million, compared to $0.1 million during the same period in 2024. The increase is primarily due to a decrease in interest income earned from our time and cash deposits, which resulted from lower average cash balances during the three months ended June 30, 2025.

Other income in the three months ended June 30, 2025 amounted to $2.9 million and mainly includes (i) a gain of $3.2 million from our investments in listed equity securities, (ii) dividend income on equity securities of $1.4 million, (iii) dividend income of $0.4 million from our investment in 140,000 1.00% Series A Fixed Rate Cumulative Perpetual Convertible Preferred Shares of Toro (the “Toro Series A Preferred Shares”), (iv) foreign exchange losses amounting to $4.1 million, and (v) other net amounting to $2.0 million due to recoveries of prior year allowances and reversals of provisions.

Dividend income from equity method investments measured at fair value (related party) amounted to $5.5 million in the six months ended June 30, 2025 and includes the dividend income from MPCC.

Other income, net in the three months ended June 30, 2024, amounted to $7.4 million, which includes (i) a gain of $5.1 million from our investments in listed equity securities, (ii) dividend income on equity securities of $2.0 million, and (iii) dividend income of $0.4 million from our investment in the Toro Series A Preferred Shares.

Recent Financial Developments Commentary:

Liquidity/Financing/Cash flow update

Our consolidated cash position as of June 30, 2025, decreased by $43.1 million to $44.8 million, as compared to our cash position on December 31, 2024, which amounted to $87.9 million. The decrease was mainly the result of: (i) $4.0 million of net operating cash outflows during the six months ended June 30, 2025, (ii) net outflows of $20.0 million associated with the sale and purchase of equity method investments, (iii) $101.1 million used for scheduled principal repayments, early prepayments in connection with the sale of vessels and voluntary prepayments, mainly to the term loan from Toro, on our debt, (iv) $2.1 million of dividends paid relating to our 5.00% Series D Cumulative Perpetual Convertible Preferred Shares, (v) $2.8 million for cash dividends paid to non-controlling interests, as offset by (vi) $61.9 million inflow of net proceeds from the sales of the M/V Ariana A, M/V Magic Eclipse, M/V Magic Callisto and M/V Gabriela A, (vii) $1.6 million proceeds related to a loan facility, and (viii) net inflows of $20.7 million associated with the purchase and sale of equity securities.

As of June 30, 2025, our total debt, gross of unamortized deferred loan fees, was $5.3 million, of which $1.2 million is repayable within one year, as compared to $103.7 million of gross total debt as of December 31, 2024, a decrease mainly due to the prepayments made in connection with vessel dispositions and voluntary prepayments of our long term debt.

More specifically, on March 24, 2025 and March 31, 2025, Castor made partial prepayments to Toro for its term loan amounting to $13,500,000 and $34,000,000, respectively, in addition to $2,500,000 as part of the scheduled repayment of the loan. On April 29, 2025 we prepaid $14,000,000 of the term loan from Toro, and on May 5, 2025, we prepaid the amount of $36,000,000 that remained outstanding as of that date.

As of June 30, 2025, the remaining debt balance of $5.3 million pertained to our asset management segment.

Recent Business Developments Commentary:

New Series E Preferred shares

On September 29, 2025, we agreed to issue 60,000 Series E Cumulative Perpetual Convertible Preferred Shares (the “Series E Preferred Shares”) having a stated amount of $1,000 each to Toro for a total consideration of $60.0 million in cash. The distribution rate of the Series E Preferred Shares is 8.75%, paid quarterly, and they are convertible into common shares of Castor from the first anniversary of the issue date at a conversion price equal to the 5-day value weighted average price immediately preceding the conversion, subject to a minimum conversion price of $0.30.

APPENDIX B

Non-GAAP Financial Information

Daily Time Charter (“TCE”) Rate. The Daily Time Charter Equivalent Rate (“Daily TCE Rate”) is a measure of the average daily revenue performance of a vessel. The Daily TCE Rate is not a measure of financial performance under U.S. GAAP (non-GAAP measure) and should not be considered as an alternative to any measure of financial performance presented in accordance with U.S. GAAP. We calculate Daily TCE Rate by dividing total revenues (time charter and/or voyage charter revenues, and/or pool revenues, net of charterers’ commissions), less voyage expenses, by the number of Available Days during that period. Under a time charter, the charterer pays substantially all the vessel voyage related expenses. However, we may incur voyage related expenses when positioning or repositioning vessels before or after the period of a time or other charter, during periods of commercial waiting time or while off-hire during dry-docking. Under voyage charters, the majority of voyage expenses are generally borne by us whereas for vessels in a pool, such expenses are borne by the pool operator. The Daily TCE Rate is a standard shipping industry performance measure used primarily to compare period-to-period changes in a company’s performance and management believes that the Daily TCE Rate provides meaningful information to our investors since it compares daily net earnings generated by our vessels irrespective of the mix of charter types (i.e., time charter, voyage charter, or other) under which our vessels are employed between the periods while it further assists our management in making decisions regarding the deployment and use of our vessels and in evaluating our financial performance. Our calculation of the Daily TCE Rates may be different from and may not be comparable to that reported by other companies.

The following table reconciles the calculation of the Daily TCE Rate which is applicable only for our dry bulk and containership fleet to Total vessel revenues (applicable only to dry bulk and containership segments) for the periods presented (amounts in U.S. dollars, except for Available Days):

	Three Months Ended June 30,						Six Months Ended June 30,

EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA are not measures of financial performance under U.S. GAAP, do not represent and should not be considered as an alternative to net income, operating income, cash flow from operating activities or any other measure of financial performance presented in accordance with U.S. GAAP. We define EBITDA as earnings before interest and finance costs (if any), net of interest income, taxes (when incurred), depreciation and amortization of deferred dry-docking costs. Adjusted EBITDA represents EBITDA adjusted to exclude unrealized gain/loss on equity securities and equity method investments (including those measured at fair value) and non-recurring expenses, which the Company believes are not indicative of the ongoing performance of its core operations. EBITDA and Adjusted EBITDA are used as supplemental financial measure by management and external users of financial statements to assess our operating performance. We believe that EBITDA and Adjusted EBITDA assists our management by providing useful information that increases the comparability of our operating performance from period to period and against the operating performance of other companies in our industry that provide EBITDA information. This increased comparability is achieved by excluding the potentially disparate effects between periods or companies of interest, other financial items, depreciation and amortization and taxes for EBITDA, and further excluding unrealized gains/loss on securities and non-recurring expenses for Adjusted EBITDA, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect net income between periods. We believe that including EBITDA and Adjusted EBITDA as measures of operating performance benefits investors in (a) selecting between investing in us and other investment alternatives and (b) monitoring our ongoing financial and operational strength. Our basis of computing EBITDA and Adjusted EBITDA as presented below may be different from and may not be comparable to similarly titled measures of other companies.

The following table reconciles EBITDA and Adjusted EBITDA to Net (loss)/ income, the most directly comparable U.S. GAAP financial measure, for the periods presented:

Adjusted Net Income. To derive Adjusted Net Income/(Loss) from Net Income/(Loss), we exclude certain non-cash items, as provided in the table below. We believe that Adjusted Net Income assists our management and investors by increasing the comparability of our performance from period to period since each such measure eliminates the effects of such non-cash item as unrealized losses from investments measured at fair value and other items which may vary from year to year, for reasons unrelated to overall operating performance. Our method of computing Adjusted Net Income may not necessarily be comparable to other similarly titled captions of other companies due to differences in methods of calculation. The following table reconciles Adjusted Net Income for the periods presented:

In addition to these important factors, other important factors that, in our view, could cause actual results to differ materially from those discussed in the forward‐looking statements include generally: the effects of the spin-off of our tanker business, the effects of our acquisition of MPC Münchmeyer Petersen Capital AG, our business strategy, expected capital spending and other plans and objectives for future operations, dry bulk and containership market conditions and trends, including volatility in charter rates (particularly for vessels employed in short-term time charters or index linked period time charters), factors affecting supply and demand, fluctuating vessel values, opportunities for the profitable operations of dry bulk and container vessels and the strength of world economies, changes in the size and composition of our fleet, our ability to realize the expected benefits from our past or future vessel acquisitions, our ability to realize the expected benefits of vessel acquisitions, increased transactions costs and other adverse effects (such as lost profit) due to any failure to consummate any sale of our vessels, our relationships with our current and future service providers and customers, including the ongoing performance of their obligations, dependence on their expertise, compliance with applicable laws, and any impacts on our reputation due to our association with them, our ability to borrow under existing or future debt agreements or to refinance our debt on favorable terms and our ability to comply with the covenants contained therein, in particular due to economic, financial or operational reasons, our continued ability to enter into time or voyage charters with existing and new customers and to re-charter our vessels upon the expiry of the existing charters, changes in our operating and capitalized expenses, including bunker prices, dry-docking, insurance costs, costs associated with regulatory compliance, and costs associated with climate change, our ability to fund future capital expenditures and investments in the acquisition and refurbishment of our vessels (including the amount and nature thereof and the timing of completion thereof, the delivery and commencement of operations dates, expected downtime and lost revenue), instances of off-hire, due to vessel upgrades and repairs, competition in the shipping and energy infrastructure management business, our ability to identify and develop new investment projects, our ability to maintain and increase the volume of the assets under our management and therefore our ability to earn fees, the financial performance or our investees over which we do not exercise control, fluctuations in interest rates and currencies, including the value of the U.S. dollar relative to other currencies, any malfunction or disruption of information technology systems and networks that our operations rely on or any impact of a possible cybersecurity breach, existing or future disputes, proceedings or litigation, future sales of our securities in the public market and our ability to maintain compliance with applicable listing standards, volatility in our share price, including due to high volume transactions in our shares by retail investors, potential conflicts of interest involving affiliated entities and/or members of our board of directors, senior management and certain of our service providers that are related parties, general domestic and international political conditions or events, including armed conflicts such as the war in Ukraine and the conflict in the Middle East, acts of piracy or maritime aggression, such as recent maritime incidents involving vessels in and around the Red Sea, sanctions, “trade wars”, tariffs, global public health threats and major outbreaks of disease, changes in seaborne and other transportation, including due to the maritime incidents in and around the Red Sea, fluctuating demand for dry bulk and container vessels and/or disruption of shipping routes due to accidents, political events, international sanctions, international hostilities and instability, piracy or acts of terrorism, changes in governmental rules and regulations or actions taken by regulatory authorities, including changes to environmental regulations applicable to the shipping industry, accidents, the impact of adverse weather and natural disasters and any other factors described in our filings with the SEC. The information set forth herein speaks only as of the date hereof, and we disclaim any intention or obligation to update any forward looking statements as a result of developments occurring after the date of this communication, except to the extent required by applicable law. New factors emerge from time to time, and it is not possible for us to predict all or any of these factors. Further, we cannot assess the impact of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement. Please see our filings with the Securities and Exchange Commission for a more complete discussion of these foregoing and other risks and uncertainties. These factors and the other risk factors described in this press release are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Given these uncertainties, investors are cautioned not to place undue reliance on such forward-looking statements.
