INTERNATIONAL SEAWAYS REPORTS

THIRD QUARTER 2025 RESULTS

New York, NY – November 6, 2025– International Seaways, Inc. (NYSE: INSW) (the “Company,” “Seaways,” or “INSW”), one of the largest tanker companies worldwide providing energy transportation services for crude oil and petroleum products, today reported results for the third quarter 2025.

HIGHLIGHTS & RECENT DEVELOPMENTS

Quarterly Results:

Fleet Optimization Program:

Healthy Balance Sheet:

Returns to Shareholders:

Lois K. Zabrocky, International Seaways President and CEO commented, “Seaways delivered another strong quarter of results, with solid contributions from all our asset classes in both crude and products. We continued to strengthen our platform through consistent shareholder returns, disciplined fleet renewal, and ongoing balance sheet optimization. We sold our oldest vessels, took delivery of two of six LR1 newbuildings, and completed a NOK bond transaction that will ultimately unencumber six vessels and enhance our financial flexibility.  As we continue to pull all the levers of capital allocation, we are pleased to deliver a consistent payout ratio of at least 75% of adjusted net income.”

Ms. Zabrocky continued, “Market conditions strengthened late in the third quarter and have remained firm, with forward fixtures well above year-ago levels. Looking ahead, fundamentals point to continued strength in tanker rates in the near term. Tanker demand is supported by oil demand growth of about 1% and oil supply growth from the Americas and OPEC+. There may be some restocking of inventory that should continue to support trade flows following last year’s draws. Geopolitical factors continue to create inefficiencies in the global trade that absorb tonnage, while fleet growth is modest at around 2%. Tanker supply remains constrained and the gap between older ships and the orderbook exceeds three to one.”

Jeff Pribor, the Company’s CFO stated, “During the quarter, we successfully completed a bond offering on attractive terms, marking an important milestone in diversifying our capital structure and broadening our access to new investor markets. The proceeds were used to retire higher-cost debt that had been instrumental in financing the company’s earlier growth. Combined with our low cash break-even under $15,000 per day in 2026 and disciplined balance sheet management, this transaction further enhances our financial flexibility and supports long-term value creation.”

THIRD QUARTER 2025 RESULTS

Net income for the third quarter of 2025 was $71 million, or $1.42 per diluted share, compared to net income of $92 million, or $1.84 per diluted share, for the third quarter of 2024. The decrease in results was primarily driven by lower TCE revenues(1) from spot earnings of approximately $3,300 per day across the total fleet and fewer revenue days.

Shipping revenues for the third quarter were $196 million, compared to $225 million for the third quarter of 2024. TCE revenues(1) for the third quarter were $192 million, compared to $220 million for the third quarter of 2024.

Adjusted EBITDA(1) for the third quarter was $108 million, compared to $130 million for the third quarter of 2024.

Crude Tankers

Shipping revenues for the Crude Tankers segment were $96 million for the third quarter of 2025, compared to $103 million for the third quarter of 2024. TCE revenues(1) were $93 million for the third quarter, compared to $99 million for the third quarter of 2024. This decrease was attributable to fewer revenue days for VLCCs and average spot earnings of the Suezmax sector of approximately $33,300 per day compared with $38,000 per day during the third quarter of 2024.

Product Carriers

Shipping revenues for the Product Carriers segment were $100 million for the third quarter of 2025, compared to $122 million for the third quarter of 2024. TCE revenues(1) were $99 million for the third quarter of 2025, compared to $121 million for the third quarter of 2024. The decrease is primarily attributable to fewer revenue days and average spot earnings in the LR1 and MR classes of approximately $34,600 and $25,600 per day, respectively, compared with approximately $46,900, and $29,000 per day, respectively in the third quarter of 2024.

FLEET OPTIMIZATION PROGRAM

During the third quarter of 2025, the Company took delivery of the Seaways Alacran, the first of six LR1 newbuildings under construction in Korea with K Shipbuilding Co., Ltd. The aggregate contract price for the six scrubber-fitted, dual-fuel ready LR1 vessels is approximately $359 million. As of September 30, 2025, the Company has approximately $230 million in remaining construction costs, of which approximately $200 million is expected to be drawn from the ECA Credit Facility in accordance with the delivery schedule.

During the third quarter, the Company sold five vessels, including three MRs and two LR1s, with an average age of 17.7 years for net proceeds of $67 million. During the nine months ended September 30, 2025, the Company has sold seven vessels, five MRs and two LR1s, with an average age of 17.7 years for proceeds of approximately $95 million, excluding two vessels that were swapped in early 2025.

In the first quarter of 2025, the Company concluded a vessel swap to exchange two of our oldest VLCCs and $3 million in cash for three 2015-built MRs through a series of individual vessel sales and purchase agreements with the same counterparty. Due to the timing of the transactions, the Company received net proceeds during the first quarter of 2025 of $50 million and paid $53 million in the fourth quarter of 2024.

In August 2025, the Company agreed to purchase a 2020-built, scrubber-fitted VLCC for $119 million that is expected to deliver during the fourth quarter of 2025. During the third quarter of 2025, the Company paid $12 million in connection with the agreement. The remainder of the purchase price is expected to be funded by proceeds from vessel sales and available liquidity.

As of October 1, 2025, the Company has 14 vessels on time charter agreements with an average duration of 1.5 years and total future contracted revenues through expiry of approximately $229 million, excluding any applicable profit share.

BALANCE SHEET ENHANCEMENTS

In September 2025, the Company successfully issued $250 million of senior unsecured bonds maturing in 2030 in the Norwegian bond market at a coupon rate of 7.125%. Proceeds from the issuance will be used for the exercise of declared purchase options on existing sale leaseback arrangements bearing interest at SOFR plus 405 basis points with an 18-year amortization profile. The purchase options are scheduled to be paid in November 2025 for $258 million, which will unencumber six VLCCs, reduce interest expense and eliminate approximately $22 million in annual mandatory principal payments.

In August 2025, the Company entered into the ECA Credit Facility with DNB Bank and K-Sure for up to $240 million, secured by six LR1 newbuildings delivering between the third quarter of 2025 and the third quarter of 2026. The 12-year facility combines for a 20-year amortization profile and a blended interest rate of SOFR plus 125 basis points across two tranches. Funds will be drawn under the facility in connection with the delivery of each vessel. In September 2025, the Company drew $41 million on the facility in connection with the delivery of the Seaways Alacran. In October 2025, an additional $41 million was drawn upon the delivery of the Seaways Balboa.

In the nine months ended September 30, 2025, the Company repaid $145 million on its revolving credit facilities, composed of $69 million, primarily borrowed for timing differences in connection with the vessel swap and $76 million to offset capacity reductions in our revolving credit facilities.

RETURNING CASH TO SHAREHOLDERS

In September 2025, the Company paid a combined dividend of $0.77 per share of common stock, composed of a regular quarterly dividend of $0.12 per share of common stock and a supplemental dividend of $0.65 per share.

On November 5, 2025, the Company’s Board of Directors declared a combined dividend of $0.86 per share of common stock, composed of a regular quarterly dividend of $0.12 per share of common stock and a supplemental dividend of $0.74 per share of common stock. Both dividends will be paid on December 23, 2025, to shareholders with a record date at the close of business on December 9, 2025.

In October 2025, the Company’s Board of Directors extended the expiry of the $50 million share repurchase program from the end of 2025 to the end of 2026.

Spot and Fixed TCE Rates Achieved and Revenue Days

The following tables provides a breakdown of TCE rates achieved for spot and fixed charters and the related revenue days for the three months ended September 30, 2025 and the comparable period of 2024. The information in these tables excludes commercial pool fees/commissions averaging approximately $1,004 and $954 per day for the three months ended September 30, 2025 and 2024, respectively.

(a) In May 2025, the 2010-built Seaways Raffles delivered into the Tankers International 15-plus pool, which is excluded from the average spot TCE rate presented in the table above. If the 15-plus pool was included, the average VLCC TCE spot rate would be $35,103 per day on 718 revenue days for the third quarter of 2025.

Revenue days in the above table exclude days related to full service lighterings and certain of the Company’s vessels that were employed in transitional voyages.

During the 2025 and 2024 periods, each of the Company’s LR1s participated in the Panamax International Pool and transported crude oil cargoes exclusively.

Fleet Information

As of September 30, 2025, INSW’s fleet totaled 76 vessels, of which 62 were owned and 14 were chartered in.

(1) Includes bareboat charters, but excludes vessels chartered in where the duration of the charter was one year or less at inception.

Reconciliation to Non-GAAP Financial Information

The Company believes that, in addition to conventional measures prepared in accordance with GAAP, the following non-GAAP measures may provide certain investors with additional information that will better enable them to evaluate the Company’s performance. Accordingly, these non-GAAP measures are intended to provide supplemental information, and should not be considered in isolation or as a substitute for measures of performance prepared with GAAP.

Adjusted Net Income

Adjusted net income consists of net income adjusted for the impact of certain items that we do not consider indicative of our ongoing operating performance. This measure does not represent or substitute net income or any other financial item that is determined in accordance with GAAP. While adjusted net income is frequently used as a measure of operating results and performance, it may not be necessarily comparable with other similarly titled captions of other companies due to differences in methods of calculation. The following table reconciles net income, as reflected in the condensed consolidated statement of operations, to adjusted net income:

EBITDA and Adjusted EBITDA

EBITDA represents net income before interest expense, income taxes, and depreciation and amortization expense. Adjusted EBITDA consists of EBITDA adjusted for the impact of certain items that we do not consider indicative of our ongoing operating performance. EBITDA and Adjusted EBITDA do not represent, and should not be a substitute for, net income or cash flows from operations as determined in accordance with GAAP. Some of the limitations are: (i) EBITDA and Adjusted EBITDA do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments; (ii) EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital needs; and (iii) EBITDA and Adjusted EBITDA do not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debt. While EBITDA and Adjusted EBITDA are frequently used as a measure of operating results and performance, neither of them is necessarily comparable to other similarly titled captions of other companies due to differences in methods of calculation. The following table reconciles net income as reflected in the condensed consolidated statements of operations, to EBITDA and Adjusted EBITDA:

Time Charter Equivalent (TCE) Revenues

Consistent with general practice in the shipping industry, the Company uses TCE revenues, which represents shipping revenues less voyage expenses, as a measure to compare revenue generated from a voyage charter to revenue generated from a time charter. Time charter equivalent revenues, a non-GAAP measure, provides additional meaningful information in conjunction with shipping revenues, the most directly comparable GAAP measure, because it assists Company management in making decisions regarding the deployment and use of its vessels and in evaluating their financial performance. Reconciliation of TCE revenues of the segments to shipping revenues as reported in the condensed consolidated statements of operations follow:
