NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(all tabular amounts stated in thousands of U.S. Dollars, other than share or per share data)

1.Basis of Presentation

The unaudited interim consolidated financial statements (or unaudited consolidated financial statements) have been prepared in accordance with United States generally accepted accounting principles (or GAAP). These unaudited consolidated financial statements include the accounts of Teekay Tankers Ltd. (or Teekay Tankers), which is incorporated under the laws of Bermuda, its wholly-owned subsidiaries, equity-accounted joint venture and the Entities under Common Control (as defined in note 3) (collectively, the Company).

Certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted and, therefore, these unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2024, filed on Form 20-F with the U.S. Securities and Exchange Commission (or the SEC) on March 14, 2025. In the opinion of management, these unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly, in all material respects, the Company’s unaudited consolidated financial position, results of operations, cash flows and changes in equity for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of those for a full fiscal year. Intercompany balances and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

During the three months ended June 30, 2025, the Company entered into various time deposits with financial institutions having a range of maturity dates up to five months from the origination date. The time deposits with initial maturity dates of more than three months, but less than or equal to twelve months from the origination date, are classified as short-term investments on the unaudited consolidated balance sheets. The Company classified these investments as held-to-maturity investments, which are carried at amortized cost.

2. Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (or FASB) issued Accounting Standards Update (or ASU) 2023-09, Improvements to Income Tax Disclosures (or ASU 2023-09), which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. This additional disclosure is intended to provide additional information and transparency of income tax disclosures by providing consistent categories and greater disaggregation of information in the rate reconciliation, as well as income taxes paid disaggregated by jurisdiction. The amendments in the standard are effective for annual periods beginning after December 15, 2024. Early adoption is permitted and should be applied prospectively, with retrospective application permitted. The Company will adopt this standard starting with its annual financial statements for the year ending December 31, 2025. The adoption of ASU 2023-09 is expected to result in additional disclosure for income tax reporting in the Company's consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses, which requires disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments require that, for each interim and annual reporting period, an entity:

•Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, and (d) intangible asset amortization included in each relevant expense caption on the face of the income statement within continuing operations;

•Include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements;

•Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively; and

•Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.

The amendments in the standard are effective for annual periods beginning after December 15, 2026 and for interim reporting periods beginning after December 15, 2027. Early adoption is permitted and should be applied prospectively, with retrospective application permitted. The Company expects to adopt this standard in its annual period beginning fiscal year 2027. The Company is currently evaluating the impact of this standard on its consolidated financial statements.

3. Acquisition of Entities under Common Control

On December 31, 2024, the Company acquired from Teekay Corporation Ltd. (or Teekay) (a) Teekay's Australian operations for a purchase price of $65.0 million plus a related working capital adjustment of $15.9 million and (b) all of Teekay's management service companies not previously owned by the Company for a purchase price of $17.3 million, which was the net working capital value of the entities being transferred to the Company. In addition, as part of the acquisition, Teekay transferred to the Company its $6.0 million supplemental retirement defined contribution plan liability, which relates to the management service companies included in the acquisition (collectively, the Acquired Operations). This liability was deducted from the total $98.2 million purchase price for Teekay's Australian operations and Teekay's management service companies, resulting in a net consideration of $92.2 million paid to Teekay. This

NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(all tabular amounts stated in thousands of U.S. Dollars, other than share or per share data)

acquisition is deemed to be a business acquisition between entities under common control. Accordingly, the Company has accounted for this transaction in a manner similar to the pooling of interests method. Under this method of accounting, all financial or operational information contained in the Company's unaudited consolidated financial statements for the periods prior to December 31, 2024, the date that the interests in the businesses were acquired by the Company, and during which the Company and the applicable businesses were under common control of Teekay, are retroactively adjusted or recast to include the results of these Acquired Operations and are collectively referred to as the “Entities under Common Control”.

As a result of the Company's acquisition of the Acquired Operations, the Company's unaudited consolidated financial statements prior to the transaction date of December 31, 2024 have been retroactively adjusted or recast to include 100% of the assets and liabilities and results of the Acquired Operations on a consolidated basis during the periods the Acquired Operations and the Company were under common control of Teekay. The effect of adjusting such information to accounts in periods prior to the Company's acquisition thereof is included in the Entities under Common Control in the unaudited consolidated financial statements. All intercorporate transactions between the Company and the Acquired Operations that occurred prior to the acquisition by the Company have been eliminated upon consolidation.

Assets and liabilities of the Acquired Operations are reflected on the Company’s unaudited consolidated balance sheets at the historical carrying values of the Acquired Operations. The purchase price of $98.2 million that was in excess of the Acquired Operations' historical carrying value of the net assets acquired of $36.8 million has been accounted for as a $61.4 million return of capital to Teekay.

The effect of adjusting the Company’s unaudited consolidated financial statements to account for this common control transaction increased the Company’s net income for the three and six months ended June 30, 2024 by $4.2 million and $8.3 million, respectively. The adjustments for the Entities under Common Control related to this transaction increased the Company’s revenues for the three and six months ended June 30, 2024 by $31.6 million and $61.6 million, respectively.

4. Revenues

The Company’s primary source of revenue is from chartering its vessels (Suezmax tankers, Aframax tankers and Long Range 2 (or LR2) tankers) to its customers and providing operational and maintenance marine services through its Australian operations. The Company utilizes two primary forms of contracts, consisting of voyage charters and time charters.

The extent to which the Company employs its vessels on voyage charters versus time charters is dependent upon the Company’s chartering strategy and the availability of time charters. Spot market rates for voyage charters are volatile from period to period, whereas time charters provide a stable source of monthly revenue. The Company also provides ship-to-ship (or STS) support services, which include managing the process of transferring cargo between seagoing ships positioned alongside each other, as well as management services to third-party owners of vessels. For descriptions of these types of contracts, see "Item 18 – Financial Statements: Note 4" in the Company’s audited consolidated financial statements filed with its Annual Report on Form 20-F for the year ended December 31, 2024.

Charters-out

As at June 30, 2025, one (December 31, 2024 - two) of the Company’s vessels operated under a fixed-rate time-charter contract, which is scheduled to expire in May 2029. As at June 30, 2025, the minimum scheduled future revenues to be received by the Company under this time charter were approximately $3.9 million (remainder of 2025), $7.7 million (2026), $7.7 million (2027), $7.7 million (2028), and $2.6 million (2029). The hire payments should not be construed to reflect a forecast of total charter hire revenue for any of the periods.

5. Segment Reporting

The Company has two operating segments: 1) tankers, which consists of the operation of all of the Company's tankers (including the operations from those tankers employed on full service lightering contracts), and the Company's U.S.-based ship-to-ship support service operations (including its lightering support services provided as part of full service lightering operations); and 2) marine services, which consists of operational and maintenance marine services provided to the Australian government, Australian energy companies and other third parties. As a result of the Company's acquisition of the Acquired Operations, the marine services operating segment is retroactively included in the Company's segment reporting for all periods prior to the transaction date of December 31, 2024. The primary focus of the Company’s organizational structure, internal reporting and allocation of resources by the chief operating decision maker (or CODM) is based on these two segments, both of which are presented accordingly on this basis. The CODM is the President and Chief Executive Officer of the Company. The CODM uses income from operations to assess the performance of each segment and to make decisions about allocating resources. The CODM does not assess the performance of each segment by geographic regions.

The accounting policies of the two segments are the same as those described in the summary of significant accounting policies. The measure of segment assets is reported on the balance sheet as total consolidated assets.

The following table includes the Company’s revenues, expenses, other segment items, income from operations and equity income by segment, and reconciles such amounts to the Company’s consolidated net income before income tax for the periods presented in these financial statements:

(1)Relates to the Company's obligation pertaining to the European Union FuelEU Maritime regulation which became effective as of January 1, 2025 in relation to certain voyages when not using low emission intensity fuels.

Obligation Related to EU ETS

As at June 30, 2025, the Company has recorded an obligation of $10.4 million (December 31, 2024 - $6.6 million) related to its emissions levels, of which $5.7 million (December 31, 2024 - $6.6 million) is related to the Company's 2024 emissions levels and was included as part of accrued liabilities and the remaining $4.7 million (December 31, 2024 - $nil) is related to the Company's 2025 emissions levels and was included as part of other-long term liabilities in the unaudited consolidated balance sheets. During the three and six months ended June 30, 2025, the Company also recognized expenses related to EU ETS of $2.1 million and $4.8 million (2024 - $1.3 million and $3.3 million), respectively, as part of voyage expenses in the unaudited consolidated statements of income.


Other Long-Term Liabilities	As at
	June 30, 2025	December 31, 2024
	$	$
Freight tax provision (note 15)	37,291	41,404

Defined contribution pension liability	4,800	5,091
Other	606	1,467
Other long-term liabilities	56,381	56,660

8. Long-Term Debt

As at June 30, 2025, the Company had one revolving credit facility (or the 2023 Revolver), which, as at such date, provided for aggregate borrowings of up to $220.1 million (December 31, 2024 - $254.0 million), of which $220.1 million (December 31, 2024 - $254.0 million) was undrawn. The 2023 Revolver matures in May 2029, and interest payments are based on the Secured Overnight Financing Rate (or SOFR) plus a margin of 2.00%, which, if the 2023 Revolver had been drawn, would have resulted in an interest rate of 6.3% as of June 30, 2025 (December 31, 2024 - 6.3%). As of June 30, 2025, the total amount available under the 2023 Revolver was scheduled to decrease by $33.9 million (remainder of 2025), $66.4 million (2026), $55.0 million (2027), $43.3 million (2028) and $21.5 million (2029). As of June 30, 2025, the 2023 Revolver was collateralized by 19 of the Company's vessels, together with other related security.

The 2023 Revolver requires the Company to maintain a minimum hull coverage ratio of 125% of the total outstanding drawn balance for the facility. This requirement is assessed on a semi-annual basis with reference to vessel valuations compiled by two or more agreed upon third parties. Should this ratio drop below the required amount, the lenders may request that the Company either prepay a portion of the loan in the amount of the shortfall or provide additional collateral in the amount of the shortfall, at the Company's option. As at June 30, 2025, the hull coverage ratio for the 2023 Revolver was not applicable due to no balance being drawn. In addition, the Company is required to maintain a minimum liquidity (cash, cash equivalents and undrawn committed revolving credit lines with at least six months to maturity) of the greater of $35.0 million and at least 5% of the Company's total consolidated debt. As at June 30, 2025, the Company was in compliance with all covenants in respect of the 2023 Revolver.

9. Operating Leases

The Company charters-in vessels from other vessel owners on time charter-in contracts, whereby the vessel owner provides use and technical operation of the vessel for the Company, and also on bareboat-in contracts, whereby the registered owner provides the vessel to the Company during which the Company is entirely responsible for the operation of the vessel, including technical services and the crew required for operation. Time charter-in contracts and bareboat-in contracts are typically for a fixed period of time, although in certain cases the Company may have the option to extend the charter. The Company typically pays the owner a daily hire rate that is fixed over the duration of the charter. Under time charter-in contracts, the Company is generally not required to pay the daily hire rate during periods the vessel is not able to operate, whereas this does not generally apply to bareboat-in contracts.

As at June 30, 2025, minimum commitments to be incurred by the Company under time charter-in contracts and bareboat-in contracts were approximately $20.0 million (remainder of 2025), $24.9 million (2026), $15.1 million (2027), $8.5 million (2028), and $7.4 million (2029).

10. Fair Value Measurements

For a description of how the Company estimates fair value and for a description of the fair value hierarchy levels, see "Item 18 – Financial Statements: Note 12" to the Company’s audited consolidated financial statements filed with its Annual Report on Form 20-F for the year ended December 31, 2024.

The following table includes the estimated fair value, carrying value and categorization using the fair value hierarchy of those assets and liabilities that are measured at their estimated fair value on a recurring and non-recurring basis, as well as certain financial instruments that are not measured at fair value on a recurring basis.

Advances to equity-accounted joint venture	Level 2	380	380	380	Note (2)

(1)As at June 30, 2025, the Company has recorded an obligation related to EU ETS for $10.4 million, of which $5.7 million (December 31, 2024 - $6.6 million) was included as part of accrued liabilities and the remaining balance of $4.7 million (December 31, 2024 - $nil) was included as part of other-long term liabilities in the unaudited consolidated balance sheets. This amount can include an accrual representing the difference between the total emissions liability and the carrying value of the EUAs held as at the end of the reporting period. The fair value of the accrual is estimated using the fair market value of an EUA that is traded on a regulated energy exchange at the end of the reporting period. As at June 30, 2025, no such accrual was made as the total emissions liability was less than the carrying value of the EUAs held (December 31, 2024 - $0.7 million).

(2)The advances to its equity-accounted joint venture, together with the Company’s investment in the equity-accounted joint venture, form the net aggregate carrying value of the Company’s interests in the equity-accounted joint venture in these unaudited consolidated financial statements. In July 2025, the Company signed an agreement to acquire the Very Large Crude Carrier (or VLCC) that is currently owned through the equity-accounted joint venture. The acquisition is expected to be completed in the third quarter of 2025, at which time the equity-accounted joint venture will use the proceeds to pay off any outstanding obligations, which include the Company's advances to its equity-accounted joint venture. As at June 30, 2025, the fair value of the Company's advances to its equity-accounted joint venture approximates the carrying value of the advances. As at December 31, 2024, the fair values of the individual components of such aggregate interests were not determinable.

The Company is exposed to credit loss in the event of non-performance by the financial institutions where its cash, cash equivalents and short-term investments are held. In order to minimize credit risk, the Company only places deposits and short-term investments with counterparties that are rated A- or better by Standard & Poor’s or A3 or better by Moody’s at the time of the transaction. In addition, to the extent practical, cash deposits and short-term investments are held by and entered into with, as applicable, different counterparties to reduce concentration risk.

The Company's investment in marketable securities is exposed to equity price fluctuations that could have an impact on the fair value of the investment.

(all tabular amounts stated in thousands of U.S. Dollars, other than share or per share data)

b)Purchase Commitment

In June 2025, the Company signed an agreement to acquire one 2017-built Suezmax tanker for a purchase price of $64.3 million (note 20).

c)Legal Proceedings and Claims

The Company may, from time to time, be involved in legal proceedings and claims that arise in the ordinary course of business. The Company believes that any adverse outcome of existing claims, individually or in the aggregate, would not have a material effect on its financial position, results of operations or cash flows, when taking into account its insurance coverage and indemnifications from charterers.

d)Other

The Company enters into indemnification agreements with certain officers and directors. In addition, the Company enters into other indemnification agreements in the ordinary course of business. The maximum potential amount of future payments required under these indemnification agreements is unlimited. However, the Company maintains what it believes is appropriate liability insurance that reduces its exposure and enables the Company to recover future amounts paid up to the maximum amount of the insurance coverage, less any deductible amounts pursuant to the terms of the respective policies, the amounts of which are not considered material.

20. Subsequent Events

a.In July 2025, the Company completed the purchase of the 2017-built Suezmax tanker as described in note 19 using cash on hand.

b.In July 2025, the Company signed an agreement to acquire one 2013-built VLCC for a purchase price of $63.0 million. The VLCC is currently owned through the Company's 50/50 joint venture, and the vessel is expected to be delivered to the Company during the third quarter of 2025. Upon completion of the sale of this VLCC to the Company, the joint venture will be unwound and net proceeds, after the repayment of debt totaling $15.0 million and settlement of working capital, will be distributed to the shareholders of the joint venture.

c.In July 2025, the Company signed an agreement to sell one Suezmax tanker for a price of $34.5 million. The vessel was classified as held for sale as at June 30, 2025, and it is expected to be delivered to the purchaser during the third or fourth quarter of 2025.

d.In July 2025, the Company's Board of Directors declared a fixed quarterly cash dividend in the amount of $0.25 per outstanding common share for the quarter ended June 30, 2025. The dividend is payable on August 22, 2025 to all of Teekay Tankers Ltd.'s shareholders of record on August 11, 2025.

PART I - FINANCIAL INFORMATION

ITEM 2 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the unaudited consolidated financial statements and accompanying notes contained in "Item 1 – Financial Statements" of this Report on Form 6-K and with our audited consolidated financial statements contained in "Item 18 – Financial Statements" and "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in "Item 5 – Operating and Financial Review and Prospects" of our Annual Report on Form 20-F for the year ended December 31, 2024.

OVERVIEW

Our primary business is to own and operate crude oil and product tankers, and we employ a chartering strategy that seeks to capture upside opportunities in the tanker spot market while using fixed-rate time charters and full service lightering (or FSL) contracts to reduce potential downside risks. Our mix of vessels trading in the spot market or subject to fixed-term time charters will change from time to time. In addition to our core business, we also provide operational and maintenance marine services and ship-to-ship (or STS) support services, along with our tanker commercial management and technical management operations. As at June 30, 2025, our fleet consisted of 44 vessels, including seven chartered-in vessels and one 50%-owned Very Large Crude Carrier (or VLCC). The following table summarizes our fleet as at June 30, 2025:


	Owned Vessels	Chartered-in Vessels	Total

Fixed-rate:



Total Fixed-Rate Fleet	—	—	—

Spot-rate:
Suezmax Tankers (1)(2)	20	1	21
Aframax Tankers / LR2 Product Tankers (3)(4)	16	3	19
VLCC Tanker (5)	1	—	1
Total Spot Fleet (6)	37	4	41
STS Support and Bunker Tanker Vessels (7)	—	3	3
Total Teekay Tankers Fleet	37	7	44

(1)Includes four owned Suezmax tankers for which agreements were put in place between May 2025 and July 2025 to sell these vessels. The four tankers are expected to be delivered to their purchasers during the third or fourth quarter of 2025 and are all classified as held for sale as at June 30, 2025.

(2)The Suezmax tanker is currently time chartered-in for a period of 54 months expiring in June 2027 with an option to extend for one year.

(3)Includes one owned Aframax / LR2 tanker for which an agreement was put in place in June 2025 to sell the vessel. The tanker is expected to be delivered to its purchaser during the third quarter of 2025 and is classified as held for sale as at June 30, 2025.

(4)Includes one chartered-in Aframax / LR2 tanker that was redelivered to its owner in July 2025. One Aframax / LR2 tanker is currently time chartered-in for a period expiring in February 2026 with an option to extend for one year. One 2023-built Aframax / LR2 tanker is currently time chartered-in for a period expiring in January 2030 with three one-year extension option periods and a purchase option at the end of the second extension option period.

(5)The VLCC is owned through a 50/50 joint venture (or High-Q joint venture). As at June 30, 2025, the VLCC was trading on spot voyage charters in a pooling arrangement managed by a third party. In July 2025, we signed an agreement to acquire the remaining 50% ownership interest in the VLCC, which is expected to be delivered to us during the third quarter of 2025.

(6)As at June 30, 2025, a total of 40 of our owned and chartered-in vessels, as well as three vessels not in our fleet and owned by third parties, were subject to revenue sharing agreements (or RSAs).

(7)Includes one bunker tanker which is currently chartered-in for a period expiring in May 2029. This bunker tanker is time chartered-out for the same corresponding period.

ITEMS YOU SHOULD CONSIDER WHEN EVALUATING OUR RESULTS

There are a number of factors that should be considered when evaluating our historical financial performance and assessing our future prospects, and we use a variety of financial and operational terms and concepts when analyzing our results of operations. These items can be found in "Item 5 – Operating and Financial Review and Prospects" in our Annual Report on Form 20-F for the year ended December 31, 2024.

SIGNIFICANT DEVELOPMENTS IN 2025

Global Tariffs and Trade

During 2025, the U.S. administration has announced and taken actions to implement new or increased tariffs on foreign imports, which has resulted or may result in retaliatory tariffs being levied on certain U.S. goods and commodities and which may trigger trade wars. This activity has disrupted global markets, resulting in significant volatility in stock and commodity prices and an increase in general global economic uncertainty, including an increased risk of economic recessions. As a result of this rapidly changing and unpredictable geopolitical climate, the shipping industry is experiencing uncertainty as to future vessel demand, trade routes, rates and operating costs.

Increased U.S. Port Fees for Chinese-Built Ships

In April 2025, the Office of the U.S. Trade Representative (or USTR) announced that additional port docking fees will apply to Chinese-built ships docking at U.S. ports starting in October 2025, including Chinese-built ships owned by non-Chinese companies. Chinese vessel owners and operators are expected to be subject to fees starting at $50 per net ton, and non-Chinese operators using Chinese-built vessels are expected to be subject to fees starting at $18 per net ton, in each case, subject to annual fee increases. As a result, Chinese-built tankers importing oil and oil products into the United States may be subject to significant additional fees, potentially disrupting the competitive landscape within the tanker industry and global tanker trade routes. At this time, although we have certain Chinese-built vessels in our fleet, we are unable to determine with certainty the impact these additional fees will have on us, our operations or our industry.

Vessel Sales

During the first quarter of 2025, we entered into agreements to sell four Suezmax tankers and two Aframax / LR2 tankers for a total price of $182.5 million, which resulted in an aggregate gain on sales of $13.9 million and $52.9 million during the three and six months ended June 30, 2025, respectively. These six tankers were delivered to their purchasers during February 2025, March 2025, April 2025, and May 2025.

During the second quarter of 2025 and July 2025, we entered into agreements to sell four Suezmax tankers and one Aframax / LR2 tanker, for a total price of $158.5 million. These five tankers are expected to be delivered to their purchasers during the third or fourth quarter of 2025. All five tankers and their related bunker and lube oil inventory were classified as held for sale as at June 30, 2025.

Vessel Acquisitions

In May 2025, we completed the acquisition of one 2019-bulit Aframax / LR2 tanker for a purchase price of $63.0 million.

In June 2025, we signed an agreement to acquire one 2017-built Suezmax tanker for a purchase price of $64.3 million. The purchase of this vessel was completed in July 2025.

In July 2025, we signed an agreement to acquire one 2013-built VLCC for a purchase price of $63.0 million. The VLCC is currently owned through our 50/50 joint venture, and the vessel is expected to be delivered to us during the third quarter of 2025. Upon completion of the sale of this VLCC to us, the joint venture will be unwound and net proceeds, after the repayment of debt totaling $15.0 million and settlement of working capital, will be distributed to the shareholders of the joint venture.

Time Chartered-in Vessel

During the first quarter of 2025, one chartered-in Aframax / LR2 tanker was redelivered to its owner following the expiry of its time chartered-in contract.

Time Chartered-out Vessel

The time charter-out contract of one Aframax / LR2 tanker expired in May 2025, at which time the tanker was delivered back to us and has subsequently been trading in the spot market.

Special Cash Dividend Declaration

In May 2025, our Board of Directors declared a special cash dividend of $1.00 per common share. This dividend was paid in May 2025.

RESULTS OF OPERATIONS

In accordance with GAAP, we report gross revenues in our unaudited consolidated statements of income and include voyage expenses among our operating expenses. However, ship-owners base economic decisions regarding the deployment of their vessels upon anticipated time-charter equivalent (or TCE) rates, which represent net revenues (or income from operations before vessel operating expenses, charter hire expenses, depreciation and amortization, general and administrative expenses, gain or loss on sale and write-down of assets, and restructuring charges), which includes voyage expenses, divided by revenue days; in addition, industry analysts typically measure bulk shipping freight and hire rates in terms of TCE rates. This is because under time charter-out contracts, the customer usually pays the voyage expenses, while under voyage charters the ship-owner usually pays the voyage expenses, which typically are added to the hire rate at an

approximate cost. Accordingly, the discussion of revenue below focuses on net revenues and TCE rates (both of which are non-GAAP financial measures) where applicable.

The results of operations that follow have been divided into (a) tankers, which consists of the operation of all of our Suezmax and Aframax / LR2 tankers as well as our 50% ownership interest in a VLCC tanker (including the operations from those of our tankers employed on full service lightering contracts), and our U.S. based ship-to-ship support service operations (including our lightering support services provided as part of full service lightering operations); and (b) marine services and other, which consists of operational and maintenance marine services provided to the Australian government, Australian energy companies and other third parties, as well as management services provided to Teekay and third parties.

As a result of our acquisition on December 31, 2024 of Teekay Corporation Ltd.'s (or Teekay's) Australian operations and all of Teekay’s management service companies not previously owned by us, including the transfer to us of Teekay’s supplemental retirement defined contribution plan liability, which relates to the management service companies included in the acquisition (collectively, the Acquired Operations), all information related to these operating results for the periods prior to the respective dates the interests in the businesses were acquired by us, and during which we and the applicable businesses were under common control of Teekay, are retroactively adjusted or recast to include the results of the Acquired Operations and are collectively referred to as the “Entities under Common Control”.

Summary

Our consolidated income from operations was $129.4 million for the six months ended June 30, 2025, compared to $251.5 million in the same period last year. The primary reasons for this decrease in income are as follows:

•a decrease of $113.1 million as a result of lower overall average realized spot TCE rates earned by our Suezmax tankers and Aframax / LR2 tankers in the first half of 2025 compared to the same period in the prior year;

•a decrease of $37.5 million due to the sales of four Aframax / LR2 tankers and five Suezmax tankers between the start of the first quarter of 2024 and the end of the second quarter of 2025; and

•a decrease of $14.8 million due to the redeliveries of four chartered-in tankers to their owners during the second half of 2024 and the first quarter of 2025;

partially offset by:

•an increase of $41.3 million due to the gain on sales of two Aframax / LR2 tankers and four Suezmax tankers in the first half of 2025 compared to the gain on sale of one Aframax / LR2 tanker in the first quarter of 2024.

Details of the changes to our results of operations for the three and six months ended June 30, 2025, compared to the three and six months ended June 30, 2024, are provided below.

Three and Six Months Ended June 30, 2025 versus Three and Six Months Ended June 30, 2024

Tankers - Operating Results

We own and operate crude oil and product tankers that (i) are subject to long-term, fixed-rate time-charter contracts (which have an original term of one year or more), (ii) operate in the spot tanker market, or (iii) are subject to time charters that are priced on a spot market basis or are short-term, fixed-rate contracts (which have original terms of less than one year), including those employed on FSL contracts. In addition, we provide STS support services, along with our tanker commercial management and technical management services.

Please refer to "Item 2 – Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measure" for a definition and reconciliation of this non-GAAP financial measure to the most directly comparable financial measure calculated and presented in accordance with GAAP.

Net Revenues. Net revenues were $117.0 million and $232.6 million for the three and six months ended June 30, 2025, respectively, compared to $196.5 million and $418.3 million for the same periods in the prior year.

The net decreases for the three and six months ended June 30, 2025 compared to the same periods in the prior year were primarily the result of:

•net decreases of $43.2 million and $72.8 million for the three and six months ended June 30, 2025, respectively, due to the sales of four Aframax / LR2 tankers and five Suezmax tankers between the start of the first quarter of 2024 and the end of the second quarter of 2025, as well as the redeliveries of four chartered-in tankers to their owners during the second half of 2024 and the first quarter of 2025, partially offset by the acquisition of two Aframax / LR2 tankers between the third quarter of 2024 and the second quarter of 2025;

•decreases of $38.4 million and $113.1 million for the three and six months ended June 30, 2025, respectively, due to lower overall average realized spot rates earned by our Suezmax tankers and Aframax / LR2 tankers compared to the same periods in the prior year;

•decreases of $0.4 million and $1.1 million for the three and six months ended June 30, 2025, respectively, due to lower bunker commissions earned and lower revenues earned from our responsibilities in employing the vessels subject to RSAs compared to the same periods in the prior year;

•decreases of $0.3 million and $1.9 million for the three and six months ended June 30, 2025, respectively, primarily due to certain vessels returning from time charter-out contracts at various times and earning a lower average rate compared to the previous rate; and

•a decrease of $1.9 million for the six months ended June 30, 2025 due to one fewer calendar day compared to the same period in the prior year;

partially offset by:

•increases of $1.8 million and $3.7 million for the three and six months ended June 30, 2025, respectively, due to higher revenues related to certain STS support service activities and a higher volume of operational jobs compared to the same periods in the prior year; and

•increases of $1.0 million and $1.5 million for the three and six months ended June 30, 2025, respectively, due to fewer off-hire days and lower off-hire bunker expenses related to the timing of dry dockings compared to the same periods in the prior year.

Vessel Operating Expenses. Vessel operating expenses were $32.4 million and $68.2 million for the three and six months ended June 30, 2025, respectively, compared to $38.4 million and $75.9 million for the same periods in the prior year.

The decreases for the three and six months ended June 30, 2025 compared to the same periods in the prior year were primarily the result of:

•net decreases of $4.0 million and $5.5 million for the three and six months ended June 30, 2025, respectively, resulting from the sales of four Aframax / LR2 tankers and five Suezmax tankers between the start of the first quarter of 2024 and the end of the second quarter of 2025, partially offset by the acquisition of two Aframax / LR2 tankers between the third quarter of 2024 and the second quarter of 2025;

•a decrease of $1.1 million for the six months ended June 30, 2025 due to lower ship management costs during the first half of 2025; and

•decreases of $1.6 million and $0.7 million for three and six months ended June 30, 2025, respectively, resulting from lower repair and maintenance related expenditures during the first half of 2025.

Charter Hire Expenses. Charter hire expenses were $11.0 million and $24.8 million for the three and six months ended June 30, 2025, respectively, compared to $19.7 million and $39.2 million for the same periods in the prior year.

The net decreases for the three and six months ended June 30, 2025 compared to the same periods in the prior year were primarily the result of:

•decreases of $8.9 million and $14.8 million for the three and six months ended June 30, 2025, respectively, resulting from the redeliveries of four chartered-in tankers to their owners during the second half of 2024 and the first quarter of 2025; and

•decreases of $0.8 million and $1.5 million for the three and six months ended June 30, 2025, respectively, due to the impairments of operating lease right-of-use assets related to three chartered-in vessels between the fourth quarter of 2024 and first quarter of 2025;

partially offset by:

•increases of $1.2 million and $2.1 million for the three and six months ended June 30, 2025, respectively, resulting from an increase in the daily hire rate for one Aframax / LR2 tanker after extending its chartered-in contract during the second quarter of 2024.

Depreciation and Amortization. Depreciation and amortization was $20.9 million and $44.2 million for the three and six months ended June 30, 2025, respectively, compared to $22.4 million and $45.7 million for the same periods in the prior year. The net decreases were primarily due to the sales of three Aframax / LR2 tankers and five Suezmax tankers between the start of the fourth quarter of 2024 and the end of the second quarter of 2025, partially offset by the acquisition of two Aframax / LR2 tankers between the third quarter of 2024 and the second quarter of 2025, as well as the dry docks of certain vessels that are subject to a shorter amortization period compared to the previous dry docks.

General and Administrative Expenses. General and administrative expenses were $14.5 million and $24.2 million for the three and six months ended June 30, 2025, respectively, compared to $14.0 million and $27.8 million for the same periods in the prior year. The increase for the three months ended June 30, 2025 compared to the same period in the prior year was primarily due to higher expenditures related to equity-based compensation. The decrease for the six months ended June 30, 2025 compared to the same period in the prior year was primarily due to lower expenditures related to compensation, benefits and payroll taxes, partly resulting from organizational changes made during the second half of 2024.

Gain on Sale and Write-Down of Assets. The gain on sale and write-down of assets of $13.9 million and $52.1 million for the three and six months ended June 30, 2025, respectively, were related to:

•the sales of two Suezmax tankers, which resulted in an aggregate gain on sales of $13.9 million during the three and six months ended June 30, 2025, as well as the sales of two Aframax / LR2 tankers and two Suezmax tankers, which resulted in an aggregate gain on sales of $39.0 million during the six months ended June 30, 2025;

partially offset by:

•the impairment recorded for two of our operating lease right-of-use assets resulting from a decline in the prevailing short-term time-charter rates, which resulted in a write-down of $0.8 million during the six months ended June 30, 2025.

The gain on sale of assets of $11.6 million for the six months ended June 30, 2024 was related to the sale of one Aframax / LR2 tanker in February 2024.

Equity Income. Equity income was $0.7 million and $0.9 million for the three and six months ended June 30, 2025, respectively, compared to $0.9 million and $2.3 million for the same periods in the prior year. The decreases were primarily due to lower spot rates realized by our 50% ownership interest in a VLCC, which has been trading in a third-party managed VLCC pooling arrangement.

Tanker Market

Mid-size crude tanker spot rates improved during the second quarter of 2025 compared to the first quarter of 2025, primarily due to the impact of longer average voyage distances during April. Rates subsequently softened during the remainder of the quarter in line with normal seasonal trends, though the market saw a brief period of volatility in mid-June following the escalation of hostilities between Israel and Iran. However, there was no material disruption to regional oil production, exports, or tanker movements, with several spot charters failing subjects and rates quickly reverting to prior levels once a ceasefire was announced.

In the near term, rising crude oil production and seaborne exports during the second half of the year should be positive for tanker demand heading into the seasonally stronger winter months. The OPEC+ group continues to unwind the 2.2 million barrels per day (or mb/d) of voluntary production cuts that have been in place since late-2023 with the announcement of a 548 thousand barrels per day (or kb/d) increase during August. This follows the return of 137 kb/d of production in April and the unwinding of 411 kb/d in each of May, June, and July. By August, the group is expected to have returned 1.9 mb/d of the 2.2 mb/d in voluntary supply cuts and is expected to unwind the full amount by September 2025, a year ahead of the original schedule.

While OPEC+ is in the process of returning production to the market, we have yet to see this being fully reflected in seaborne exports as a portion of this extra production is being consumed in the Middle East to meet rising power demand during the summer months. However, we expect that Middle East crude oil exports will rise after the summer, creating additional tanker demand during the latter part of the third quarter and into the fourth quarter of 2025. New offshore oil production coming online in Brazil and Guyana should also increase overall volumes and support crude tanker tonne-mile demand during the second half of the year.

Looking further ahead, the medium-term demand outlook remains complex due to a combination of economic and geopolitical factors. Uncertainty surrounding U.S. trade tariffs continues to cloud the economic outlook, with most major forecasting agencies having lowered their outlook for global GDP and trade growth since the start of the year. As a result, the IEA has lowered its outlook for global oil demand growth in 2025 to 0.7 mb/d, compared to forecast growth of 1.0 mb/d at the start of the year, with further growth of 0.7 mb/d projected in 2026.

Geopolitical events continue to have an outsized influence on global oil and tanker markets. While the recent conflict between Israel and Iran did not have a material impact on regional oil production, exports, or tanker movements, it did highlight the importance of the region to the global oil trade with over 20 mb/d of oil flowing from the Middle East Gulf. More recently, Houthi rebels have resumed attacks on shipping in the Red Sea, which is likely to constrain vessel transits through the region and support tonne-mile demand as vessels take longer routes.

The conflict between Russia and Ukraine continues, with the EU recently implementing a new sanctions package that includes a lowering of the price cap from $60 per barrel to $47.60 per barrel, a ban on the import of refined products made from Russian crude, and the addition of 105 tankers to the sanctioned vessel list. Following the most recent round of sanctions a total of 530 Aframaxes, Suezmaxes, and VLCCs (or 19% of the fleet) with an average age of 20 years is now under some form of sanction. Should there be a reversal of sanctions, we believe that the majority of these vessels will have difficulty returning to conventional trading given that 60% are aged 20 years or older.

The pace of tanker orders(1) has slowed in 2025 with orders for just under 11 million deadweight tons (or mdwt) placed in the first half of 2025 compared to 42 mdwt in the same period of 2024. The orderbook for tankers(1), when measured as a percentage of the tanker fleet, has stabilized in recent months at approximately 15% across the tanker fleet(1). A lack of tanker scrapping means that the fleet continues to age, with the average age of the tanker fleet(1) at a 25-year high of 14.0 years as of the start of July 2025. We believe the combination of the current orderbook, an aging tanker fleet, and constraints on available yard space should result in relatively low levels of tanker fleet growth over the medium term.

In summary, we believe that the near-term outlook for spot tanker rates will be positive after the seasonally weaker summer months. However, while fleet supply fundamentals continue to look supportive, there are economic and geopolitical uncertainties that make it difficult to predict how, and along what specific timeline, things will unfold for the tanker market in the medium term.

Tankers - Fleet and TCE Rates

As at June 30, 2025, we owned 36 double-hulled oil and product tankers and time chartered-in three Aframax / LR2 tankers, one Suezmax tanker, one bunker tanker and two STS support vessels. We also owned a 50% interest in one VLCC, the results of which are included in equity income.

The following tables highlight the operating performance of our spot vessels (including those trading on voyage charters, in RSAs and in FSL) and our time charter-out vessels, measured in TCE rates, or net voyage per revenue day before costs to commercially manage our vessels, and off-hire bunker expenses:

Marine Services and Other - Operating Results

As part of our Australian operations, we provide marine services to the Australian government, energy companies and other third parties. Our marine services business in Australia provides operations, supply, maintenance and engineering support, as well as crewing and training services, primarily under long-term contracts with the Commonwealth of Australia, for 10 Australian government-owned vessels. In addition, we provide crewing services under a management contract, which will be terminated in August 2025, for an FPSO unit in Western Australia and bareboat charter-in a bunker tanker which is time chartered-out to a third party.

The following table presents the Marine Services and Other operating results for the three and six months ended June 30, 2025 and 2024:


	Three Months Ended June 30,			Six Months Ended June 30,
(in thousands of U.S. Dollars, except percentage changes)	2025	2024	% Change	2025	2024	% Change
Revenues (1)	37,216	31,671	17.5%	66,351	61,614	7.7	%
Vessel operating expenses	(28,056)	(27,387)	2.4%	(53,477)	(52,889)	1.1	%
Charter hire expenses	(627)	—	—%	(1,247)	—	—	%

Income from operations	2,965	4,740	(37.4)%	6,059	10,138	(40.2)	%

(1)Restructuring charges include severance costs of $5.6 million resulting from the termination of a management contract related to our Australian operations; the severance costs are fully recoverable from the customer, and the recovery is presented in revenues.

(2)Includes certain services which were provided to us by the Entities under Common Control, which offset the corresponding expense we paid to the Entities under Common Control prior to our acquisition of the Acquired Operations on December 31, 2024.

Income from operations for Marine Services and Other was $3.0 million and $6.1 million for the three and six months ended June 30, 2025, respectively, compared to $4.7 million and $10.1 million for the same periods in the prior year. The net decreases were primarily due to lower results from our operational and maintenance marine services in Australia related to higher crewing-related expenditures and a decrease in the number of vessels under management, as well as a reduced level of management services provided to Teekay, partially offset by the time charter-out of a bareboat charter-in bunker tanker that commenced in the fourth quarter of 2024.

Other Consolidated Operating Results

The following table compares our other consolidated operating results for the three and six months ended June 30, 2025 and 2024:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands of U.S. Dollars, except percentage changes)	2025	2024	% Change		2025	2024	% Change
Interest expense	(777)	(979)	(20.6)	%	(1,550)	(5,846)	(73.5)	%
Interest income	7,568	6,103	24.0	%	13,425	11,750	14.3	%
Other (expense) income	(257)	2,023	(112.7)	%	(4,415)	1,264	(449.3)	%
Income tax recovery (expense)	432	(3,789)	(111.4)	%	902	(942)	(195.8)	%

Interest Expense. Interest expense was $0.8 million and $1.6 million for the three and six months ended June 30, 2025, respectively, compared to $1.0 million and $5.8 million for the same periods in the prior year. The decrease for the six months ended June 30, 2025 was primarily due to the repurchase of eight Suezmax tankers during the first quarter of 2024, all of which were previously held under sale-leaseback arrangements.

Interest Income. Interest income was $7.6 million and $13.4 million for the three and six months ended June 30, 2025, respectively, compared to $6.1 million and $11.8 million for the same periods in the prior year. The net increases were primarily due to higher average balances for cash and short-term investments, partially offset by a lower average interest rate.

Other (expense) income. Other expense was $0.3 million and $4.4 million for the three and six months ended June 30, 2025, respectively, compared to other income of $2.0 million and $1.3 million for the same periods in the prior year. The changes were primarily due to unrealized losses on marketable securities recognized in the first half of 2025 and changes in foreign currency exchange rates related to our accrued tax and working capital balances. The result for the six months ended June 30, 2025 also included premiums paid during the first quarter of 2024 in relation to the repurchase of eight Suezmax tankers which were previously under sale-leaseback arrangements.

Income Tax Recovery (Expense). Income tax recovery was $0.4 million and $0.9 million for the three and six months ended June 30, 2025, respectively, compared to income tax expense of $3.8 million and $0.9 million for the same periods in the prior year. The changes were primarily due to higher recoveries during the first half of 2025 related to the expiry of the tax limitation period in certain jurisdictions, as well as changes in vessel trading activities. The results for the six months ended June 30, 2025 include a partial offset related to the reversal of certain freight tax liabilities during the first quarter of 2024 based on an assessment of our tax position for a certain jurisdiction. For additional information, please read "Item 1 – Financial Statements: Note 16 - Income Tax Recovery (Expense)" of this report.

LIQUIDITY AND CAPITAL RESOURCES

Sources and Uses of Capital

We generate cash flows primarily from chartering out our vessels, from managing vessels for the Australian government and from providing management services to Teekay and certain third parties. We employ a chartering strategy for our tanker segment that seeks to capture upside opportunities in the tanker spot market while using fixed-rate time charters and FSL contracts to reduce potential downside risks. Our short-term charters and spot market tanker operations contribute to the volatility of our net operating cash flow, and thus may impact our ability to generate sufficient cash flows to meet our short-term liquidity needs. Historically, the tanker industry has been cyclical, experiencing volatility in profitability and asset values resulting from changes in the supply of, and demand for, vessel capacity. In addition, tanker spot markets historically have exhibited seasonal variations in charter rates. Tanker spot markets are typically stronger in the winter months as a result of increased oil consumption in the northern hemisphere and unpredictable weather patterns that tend to disrupt vessel scheduling. However, there can be other factors that override typical seasonality, such as global oil trade routes and tonne-mile demand being impacted by Russia's invasion of Ukraine or attacks by Houthi rebels on vessels in the Red Sea area. While exposure to the volatile spot market is the largest potential cause for changes in our net operating cash flow from period to period, variability in our net operating cash flow also reflects changes in interest rates, fluctuations in working capital balances, the timing and the amount of dry-docking expenditures, repairs and maintenance activities, the average number of vessels in service, including chartered-in vessels, and vessel acquisitions or vessel dispositions, among other factors. The number of vessel dry dockings varies each period depending on vessel maintenance schedules.

Our other primary sources of cash are short-term investments, long-term bank borrowings, lease or equity financings, and the proceeds from the sales of our older vessels.

As of June 30, 2025, we have one credit facility, our 2023 Revolver, and we had no vessels subject to financing leases. Our 2023 Revolver is described in "Item 1 – Financial Statements: Note 8 - Long-Term Debt" of this report. Our 2023 Revolver contains covenants and other restrictions that we believe are typical of debt financing collateralized by vessels, including those that restrict the relevant subsidiaries from: incurring or guaranteeing additional indebtedness; making certain negative pledges or granting certain liens; and selling, transferring, assigning or conveying assets. Our 2023 Revolver requires us to maintain certain financial covenants. The terms of and compliance with these financial covenants are described in further detail in "Item 1 – Financial Statements: Note 8 - Long-Term Debt" of this report. If we do not meet these financial or other covenants, the lenders may declare our obligations under the agreement immediately due and payable and terminate any further loan commitments, which depending upon our other liquidity at the time, could significantly affect our short-term liquidity requirements. As at June 30, 2025, we were in compliance with all covenants under our 2023 Revolver. Our 2023 Revolver requires us to make interest payments based on SOFR plus a margin. Depending upon the amount of our floating-rate credit facility and balance from time

to time, significant increases in interest rates could adversely affect our results of operations and our ability to service our debt. From time to time, we use interest rate swaps to reduce our exposure to market risk from changes in interest rates. As at June 30, 2025, we were not committed to any interest rate swap agreements.

Our primary uses of cash include the payment of operating expenses, dry-docking expenditures, costs associated with modifications to our vessels, funding our other working capital requirements, dividend payments on our common shares, repurchase of our common shares under our share repurchase program, debt servicing costs, as well as scheduled repayments of long-term debt. In addition, we may use cash to acquire new or second-hand vessels. The timing of the acquisition of vessels depends on a number of factors, including newbuilding prices, second-hand vessel values, the age, condition and size of our existing fleet, the commercial outlook for our vessels and other considerations. As such, vessel acquisition activity may vary significantly from year-to-year.

Cash Flows

The following table summarizes our consolidated cash and cash equivalents provided by (used for) operating, financing and investing activities for the periods presented:


	Six Months Ended June 30,
	2025	2024
(in thousands of U.S. Dollars)	$	$
Net cash flow provided by operating activities	130,065	285,345
Net cash flow used for financing activities	(51,487)	(226,975)
Net cash flow provided by investing activities	56,734	12,520

Net Operating Cash Flow

The $155.3 million decrease in net operating cash flow for the six months ended June 30, 2025, compared to the same period in 2024 was primarily due to:

•a net decrease of $157.4 million in cash inflows primarily due to lower operating earnings during the first half of 2025 resulting from lower average realized spot tanker rates, the sales of four Aframax / LR2 tankers and five Suezmax tankers between the start of the first quarter of 2024 and the end of the second quarter of 2025, as well as the redeliveries of four chartered-in tankers to their owners during the second half of 2024 and the first quarter of 2025, partially offset by lower interest expense resulting from the repurchase of eight tankers during the first quarter of 2024, all of which were previously held under sale-leaseback arrangements, as well as the acquisition of two Aframax / LR2 tankers between the third quarter of 2024 and the second quarter of 2025;

partially offset by:

•an increase of $2.7 million in cash inflows related to changes in net working capital during the first half of 2025 compared to the same period of the prior year.

Net Financing Cash Flow

Net cash flow used for financing activities decreased by $175.5 million for the six months ended June 30, 2025, compared to the same period in 2024. The net decrease was primarily due to:

•a decrease of $142.2 million in cash outflows primarily due to a decrease in prepayments and scheduled repayments on our finance lease obligations resulting from the repurchase of eight Suezmax tankers under their previous sale-leaseback financing agreements in the first quarter of 2024; and

•a decrease of $33.9 million in cash outflows due to cash dividends on our common shares paid during the first half of 2025 compared to the same period of the prior year;

partially offset by:

•a decrease of $1.4 million in cash inflows due to proceeds received upon the exercise of stock options during the first half of 2025 compared to the same period of the prior year.

Net Investing Cash Flow

Net cash flow provided by investing activities increased by $44.2 million for the six months ended June 30, 2025, compared to the same period in 2024. The net increase was primarily due to:

•an increase of $160.7 million in cash inflows resulting from higher net proceeds received from the sales of two Aframax / LR2 tankers and four Suezmax tankers during the first half of 2025 compared to net proceeds received from the sale of one Aframax / LR2 tanker in the same period of the prior year;

•a decrease of $7.1 million in cash outflows resulting from a deposit paid for the purchase of an Aframax / LR2 tanker during the first half of 2024; and

•a decrease of $2.9 million in cash outflows resulting from lower capital expenditures during the first half of 2025 compared to the same period of the prior year;

partially offset by:

•an increase of $63.0 million in cash outflows resulting from the acquisition of one Aframax / LR2 tanker during the first half of 2025;

•an increase of $61.0 million in cash outflows resulting from the purchase of short-term investments during the first half of 2025; and

•an increase of $2.3 million in cash outflows resulting from an investment in marketable securities during the first half of 2025.

Liquidity

Our primary sources of liquidity are cash and cash equivalents, short-term investments, net operating cash flow, our undrawn credit facility, and capital raised through financing transactions. The primary objectives of our cash management policy are to preserve capital, to ensure that cash investments can be sold readily and efficiently, and to provide an appropriate return. The nature and extent of amounts that can be borrowed under our 2023 Revolver are described in "Item 1 – Financial Statements: Note 8 - Long-Term Debt" of this report.

For information on our dividend policy and share repurchase program, please see "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" in "Item 5 – Operating and Financial Review and Prospects" in our Annual Report on Form 20-F for the year ended December 31, 2024.

Our total consolidated liquidity, including cash, cash equivalents, short-term investments and undrawn credit facility, increased by $165.2 million during the six months ended June 30, 2025 from $765.9 million as at December 31, 2024 to $931.1 million as at June 30, 2025. The net increase during the six months ended June 30, 2025 was primarily a result of the following events or changes during the first half of 2025: $184.1 million received from the sale of two Aframax / LR2 tankers and four Suezmax tankers; $130.0 million of net operating cash inflow during the first half of 2025; and $1.5 million of proceeds received upon the exercise of stock options; partially offset by $63.0 million for the purchase of an Aframax / LR2 tanker; $51.7 million of cash dividends paid on our common shares; $33.9 million of reduction in the borrowing capacity of our 2023 revolver; $2.3 million paid for an investment in marketable securities; and $1.0 million of expenditures for capital upgrades for vessels and equipment.

We anticipate that our liquidity at June 30, 2025, combined with cash we expect to generate during the 12 months following the date of this report, will be sufficient to meet our cash requirements for at least the one-year period following the date of this report.

Our 2023 Revolver matures in May 2029, and there was no amount outstanding under the facility as at June 30, 2025. Our ability to refinance our 2023 Revolver will depend upon, among other things, the estimated market value of our vessels, our financial condition and the condition of credit markets at such time. In July 2025, we completed the purchase of a 2017-built Suezmax tanker for a purchase price of $64.3 million using cash on hand. In addition, in July 2025, we committed to the purchase of a 2013-built VLCC for a price of $63.0 million. The VLCC is currently owned through our 50/50 joint venture, and the vessel is expected to be delivered to us during the third quarter of 2025. Approximately 50% of our fleet is currently aged 15 years and older, and we may continue the process of fleet renewal in the coming years. We expect that any fleet renewal expenditures will be funded using cash on hand, short-term investments, the undrawn revolving credit facility and new financing arrangements, including bank borrowings, finance leases and, potentially, the issuance of debt and equity securities.

The following table summarizes our other contractual obligations as at June 30, 2025:



(in millions of U.S. Dollars)	Total	12 Months Following June 30, 2025	Remainder of 2026	2027	2028	2029
U.S. Dollar-Denominated Obligations



Chartered-in vessels (operating leases) (1)	75.9	26.7	18.2	15.1	8.5	7.4
Total	75.9	26.7	18.2	15.1	8.5	7.4

(1)Excludes payments required if we exercise options to extend the terms of chartered-in leases signed as of June 30, 2025.

Other risks and uncertainties related to our liquidity include changes to income tax legislation or the resolution of uncertain tax positions relating to freight tax liabilities as described in "Item 1 – Financial Statements: Note 16 - Income Tax Recovery (Expense)" of this report, which could have a significant financial impact on our business, which we cannot predict with certainty at this time. In addition, as at June 30, 2025, the High-Q joint venture had a loan outstanding with a financial institution with a balance of $15.0 million, and we guarantee 50% of the outstanding loan balance. Finally, existing or future climate control legislation or other regulatory initiatives that restrict emissions of greenhouse gases could have a significant financial and operational impact on our business, which we cannot predict with certainty at this time. Such regulatory measures could increase our costs related to operating and maintaining our vessels and require us to install new

emission controls, acquire allowances or pay taxes or penalties related to our greenhouse gas emissions, or administer and manage a greenhouse gas emissions program. The inclusion of the maritime industry in the EU ETS as of January 1, 2024, requires us to acquire allowances related to our greenhouse gas emissions as outlined in, “Item 1 – Financial Statements: Note 6 – Intangible Assets” and “Item 1 – Financial Statements: Note 7 – Accrued Liabilities and Other Long-Term Liabilities” of this report. In addition to the EU ETS, the inclusion of the FuelEU Maritime regulation by the European Union as of January 1, 2025, requires us to pay financial penalties in relation to certain voyages when not using low emission intensity fuels. Increased regulation of greenhouse gases may, in the long-term, lead to reduced demand for oil and reduced demand for our services.

CRITICAL ACCOUNTING ESTIMATES

We prepare our consolidated financial statements in accordance with GAAP, which require us to make estimates in the application of our accounting policies based on our best assumptions, judgments and opinions. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material. Accounting estimates and assumptions that we consider to be the most critical to an understanding of our financial statements because they inherently involve significant judgments and uncertainties are discussed in "Item 5 – Operating and Financial Review and Prospects" in our Annual Report on Form 20-F for the year ended December 31, 2024. There have been no significant changes to these estimates and assumptions for the six months ended June 30, 2025.

NON-GAAP FINANCIAL MEASURE

Net Revenues - Tankers

Net revenues is a non-GAAP financial measure. Consistent with general practice in the shipping industry, we use “net revenues” (defined as income or loss from operations before vessel operating expenses, charter hire expenses, depreciation and amortization, general and administrative expenses, gain or loss on sale and write-down of assets, and restructuring charges) as a measure of equating revenues generated from voyage charters to revenues generated from time charters, which assists us in making operating decisions about the deployment of our vessels and their performance. Since under time charters the charterer pays the voyage expenses, whereas under voyage charters, the ship-owner pays these expenses, we include voyage expenses in net revenues. Some voyage expenses are fixed, and the remainder can be estimated. If we, as the ship owner, pay the voyage expenses, we typically pass the approximate amount of these expenses on to our customers by charging higher rates to them. As a result, although revenues from different types of contracts may vary, the net revenues are comparable across the different types of contracts. We principally use net revenues because it provides more meaningful information to us than income from operations, the most directly comparable GAAP financial measure. Net revenues is also widely used by investors and analysts in the shipping industry for comparing financial performance between companies and to industry averages. The following table reconciles net revenues with income from operations.
