NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(all tabular amounts stated in thousands of U.S. Dollars, other than share and 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). They include the accounts of Teekay Corporation Ltd.(or Teekay), which is incorporated under the laws of Bermuda, its wholly-owned or controlled subsidiaries and any variable interest entities of which Teekay is the primary beneficiary (collectively, the Company). Teekay's controlled subsidiaries include Teekay Tankers Ltd. (NYSE: TNK) (or Teekay Tankers). Teekay and its subsidiaries, other than Teekay Tankers, are referred to herein as Teekay Parent.

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 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 consolidated financial position, results of operations, cash flows and changes in total equity for the interim periods presented. The results of operations for the six months ended June 30, 2025, are not necessarily indicative of those for a full fiscal year. Significant 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.

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 captionon 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. 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.

Page 8

TEEKAY CORPORATION LTD. AND SUBSIDIARIES

NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

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

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 3" in the Company’s audited consolidated financial statements filed with its Annual Report on Form 20-F for the year ended December 31, 2024.

Revenue Table

The following table contains a breakdown of the Company’s revenue by contract type and segment (note 4) for the six months ended June 30, 2025, and 2024. The Company's lease income consists of the revenue from its voyage charters and time charters.

(2)Relates to non-lease revenues.

(3)Includes $5.6 million related to the recovery of severance costs during the six months ended June 30, 2025, resulting from the termination of a management contract related to the Company's Australian operations (note 12).

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. Future hire payments do not include any hire payments generated from new contracts entered into after June 30, 2025, or from variable consideration, if any, under contracts. In addition, future hire payments presented above have been reduced by estimated off-hire time for required periodic maintenance and do not reflect the impact of any applicable revenue sharing arrangements whereby time-charter revenues are shared with other revenue sharing arrangement participants. Actual amounts may vary given future events such as unplanned vessel maintenance.

Contract Liabilities

As at June 30, 2025, the Company had $nil (December 31, 2024 - $2.5 million) advanced payments recognized as contract liabilities that are expected to be recognized as time-charter revenues or voyage charter revenues in subsequent periods and which are included in accrued liabilities and other on the Company's unaudited consolidated balance sheets.

4. Segment Reporting

The Company allocates capital and assesses performance from the perspective of the Company's lines of business. The Company has two primary lines of business: (1) tankers and (2) marine services. The primary focus of the Company’s internal reporting and allocation of resources by the chief operating decision maker (or CODM) is on the two lines of business and its segments are presented accordingly on this basis. The tanker segment 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). The marine services and other segment consists of operational and maintenance marine services provided to the Australian government, Australian energy companies and other third parties, and includes corporate and general administrative expense.

The CODM is the 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 accounting policies applied to the reportable segments are the same as those used in the preparation of the Company’s consolidated financial statements.

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 income before income tax for the periods presented in these financial statements:

As part of the European Union Emissions Trading System (or EU ETS) requirements, as at June 30, 2025, the Company had acquired European Union allowances (or EUAs) for $13.5 million (December 31, 2024 -$5.9 million), which were recorded as indefinite-lived intangible assets. As at June 30, 2025, $5.7 million (December 31, 2024 - $5.9 million) of these intangible assets are presented as other current assets in the unaudited consolidated balance sheets as these EUAs are related to the Company's 2024 emissions levels and will be surrendered within one year from the balance sheet date, and the remaining $7.8 million (December 31, 2024 - $nil) of EUAs are related to the Company's 2025 emissions levels and will be surrendered more than one year from the balance sheet date.

The carrying amount of intangible assets, excluding EUAs classified as other current assets, is as follows:

	As at
	June 30, 2025	December 31, 2024
	$	$
Customer relationships     At cost of $5.7 million, less accumulated amortization of $5.6 million    (2024 - cost of $5.7 million, less accumulated amortization of $5.4 million) (1)	146	307

7. Long-Term Debt

As at June 30, 2025, the Company had one revolving credit facility (or the 2023 Revolver), for which Teekay Tankers is the borrower and 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 2.0%, 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 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.

8. 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).

9. 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 11" in 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.

		June 30, 2025		December 31, 2024
	Fair Value Hierarchy Level	Carrying Amount Asset (Liability) $	Fair Value Asset (Liability) $	Carrying Amount Asset (Liability) $	Fair Value Asset (Liability) $
Recurring
Cash, cash equivalents and restricted cash	Level 1	851,522	851,522	689,004	689,004
Short-term investments	Level 1	61,000	61,000	10,000	10,000
Marketable securities	Level 1	19,681	19,681	22,442	22,442
Obligation relating to EU ETS (note 6)	Level 1	(10,428)	Note (1)	(6,588)	(6,588)
Non-recurring
Operating lease right-of-use assets	Level 2			11,735	11,735
Other
Advances to equity-accounted joint venture – long-term	Level 2	380	380	380	Note (2)

(1)As at June 30, 2025, the Company has recorded an obligation related to EU ETS of $10.4 million, of which $5.7 million (December 31, 2024 - $6.6 million) was included as part of accrued liabilities and other 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.

17. Commitments and Contingencies

a)Liquidity

Management is required to assess if the Company will have sufficient liquidity to continue as a going concern for the one-year period following the issuance of these unaudited consolidated financial statements. Based on the Company's liquidity as at the date these unaudited consolidated financial statements were issued, and from the expected cash flows from the Company's operations over the following year, the Company estimates that it will have sufficient liquidity to meet its minimum liquidity requirements under its financial covenants and to continue as a going concern for at least a one-year period following the issuance of these unaudited consolidated financial statements.

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 18).

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.

18. Subsequent Events

a.In July 2025, the Company completed the purchase of the 2017-built Suezmax tanker as described in note 17 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 totalling $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.
