Third Quarter of 2025 Compared to Second Quarter of 2025

GAAP net income for the third quarter of 2025 increased compared to the second quarter of 2025, primarily due to the $25.9 million gain from the sales of three vessels, the $8.3 million gain on distribution from equity-accounted investment, as well as the $4.6 million unrealized gain on investment in marketable securities, compared to the $13.9 million gain from the sales of two vessels in the second quarter of 2025. In addition, GAAP net income and non-GAAP adjusted net income for the third quarter of 2025 included the acquisition of three vessels during the second and third quarters of 2025, the annual recognition of equity-based compensation in the second quarter of 2025, as well as the sales of five vessels during the second and third quarters of 2025.

Third Quarter of 2025 Compared to Third Quarter of 2024

GAAP net income for the third quarter of 2025 increased compared to the same period of the prior year, primarily due to the $25.9 million gain from the sales of three vessels, the $8.3 million gain on distribution from equity-accounted investment, as well as the $4.6 million unrealized gain on investment in marketable securities for the third quarter of 2025. In addition, GAAP net income for the third quarter of 2025 included certain fleet changes resulting from the sales of 11 vessels, the acquisition of four vessels, and the redelivery of five chartered-in vessels between the start of the third quarter of 2024 and the end of the third quarter of 2025, a lower number of scheduled dry dockings, as well as lower average spot tanker rates. Non-GAAP adjusted net income for the third quarter of 2025 decreased compared to the same period of the prior year, primarily due to the aforementioned fleet changes, as well as lower average spot tanker rates.

CEO Commentary

“In the third quarter of 2025, Teekay Tankers posted its best quarterly results so far this year, generating GAAP net income of $92.1 million and adjusted net income of $53.3 million,” commented Kenneth Hvid, Teekay Tankers’ President and Chief Executive Officer. “Spot tanker rates remained counter-seasonally strong during the quarter, with rates meaningfully above the historical average for a third quarter as a result of the OPEC+ unwinding of supply cuts and seaborne crude oil trade volumes approaching all-time highs. To date in the fourth quarter, we have seen this trend continue, with spot rates strengthening and what we believe is a tanker market well-positioned for a firm winter as a result of higher seaborne crude oil trade volumes, growing trade inefficiencies due to sanctions, low global oil inventories, lower oil prices, and a weaker U.S. dollar. With our significant exposure to the spot market, Teekay Tankers is ideally suited to benefit from these anticipated tailwinds.”

“Since reporting earnings in July 2025, Teekay Tankers has continued to execute on its fleet renewal strategy. We completed the purchases of one modern Suezmax tanker and the remaining 50% ownership interest in a VLCC, and we completed four of the five previously announced vessel sales in the third and fourth quarters, with the last vessel expected to be delivered in the coming days. In addition, we took advantage of the firming time charter market and fixed out one Suezmax and two Aframax-sized tankers at attractive rates over periods ranging from 12 to 18 months.”

“With our low cash flow break-even levels, integrated operating platform, and significant balance sheet strength, we believe Teekay Tankers is well positioned to continue generating significant free cash flow, while also taking incremental steps on fleet renewal and returning capital to shareholders through our quarterly dividend.”

Summary of Recent Events

The Company time chartered-out one Suezmax tanker for $42,500 per day for one year and two Aframax-sized tankers for an average rate of $33,275 per day for periods between 12 and 18 months. Two of these charters commenced in October 2025 and the remaining charter is scheduled to commence in November 2025.

Vessel Purchases

In July 2025, the Company completed the purchase of a 2017-built Suezmax tanker for $64.3 million.

In August 2025, the Company completed the purchase of a 2013-built VLCC for a purchase price of $63 million. The VLCC was sold to the Company by the Company's 50/50 joint venture. Upon completion of the sale, the joint venture repaid outstanding debt totaling $15.0 million, settled working capital and distributed a majority of the remaining capital to the shareholders of the joint venture, which resulted in the Company recording an $8.3 million gain in equity income. The net outflow for the Company after receiving distributions was approximately $37.4 million and the Company expects the joint venture to be wound up in 2026.

Vessel Sales

In August and September 2025, the Company completed the sales of one 2006-built and two 2009-built Suezmax tankers for $97 million, which resulted in a gain on sale of $25.9 million in the third quarter of 2025.

In October 2025, the Company completed the sale of a 2009-built Suezmax tanker and the remaining 2007-built Aframax-sized tanker sale is expected to be completed by the end of October 2025. Gross proceeds for the sales were $61.5 million and the Company expects to record gains from sales of approximately $21.6 million in the fourth quarter of 2025.

The Company's Board of Directors declared its fixed quarterly cash dividend in the amount of $0.25 per outstanding common share for the quarter ended September 30, 2025. This dividend is payable on November 21, 2025 to all of Teekay Tankers' shareholders of record on November 10, 2025.

Tanker Market

Mid-size crude tanker spot rates improved counter-seasonally during the third quarter of 2025. An increase in global oil supply due to the unwinding of OPEC+ supply cuts and rising production in the Atlantic basin led to a sharp increase in global seaborne crude trade volumes during September to the highest level since early 2020. Rates were further boosted by an increase in long-haul crude oil movements between the Atlantic and Pacific basins, particularly in the Suezmax and VLCC segments.

With OPEC+ expected to continue to unwind supply cuts through at least November, we expect global seaborne trade volumes to increase further during the fourth quarter. In addition, tighter sanctions against Russia, including the recent announcement of U.S. sanctions against Russian oil producers Rosneft and Lukoil, are expected to introduce more trading inefficiencies while also pushing more seaborne trade volumes onto the compliant fleet as refiners, particularly in India, may look to reduce their purchasing of Russian oil and replace with barrels from non-sanctioned sources. We believe these factors, coupled with normal seasonal weather delays, could support a firm tanker market through the winter months.

Looking ahead, global oil demand is projected to increase by 1.1 million barrels per day (mb/d) in 2026(1). Demand could be further supported by low oil prices, a weaker U.S. dollar, and an expected surplus of oil production relative to demand which could lead to a replenishment of global oil inventories. Tanker newbuild deliveries are set to increase in 2026, although the orderbook is stable at 16% of the existing fleet size delivering over the next three years, which is in line with long-term average levels(2). The average age of the global tanker fleet currently stands at 13.2 years, which is the highest since the 1990s(2).

While the medium-term tanker market outlook appears well balanced, there are a number of geopolitical uncertainties which could influence the direction of the tanker market depending on how they unfold. These factors include, among others:

•The outcome of the war in Ukraine and of related existing or future economic sanctions against Russia and the fleet of ships transporting Russian oil;

•Unrest in the Middle East and the disruption of vessel transits through the Red Sea; and

•The impact of U.S. trade tariffs and counter-tariffs, including, among others, measures taken by the U.S. and China to charge port fees on ships owned, operated, and / or built by entities or individuals having specified relationships with the other country when calling at U.S. and Chinese ports.

In summary, the Company believes that the tanker market is set for a strong winter given expected rising seaborne trade volumes, growing trade inefficiencies due to sanctions, low global oil inventories, lower oil prices, and a weaker U.S. dollar. While fleet supply fundamentals continue to look supportive, there are a number of 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.

(1) Net revenues is a non-GAAP financial measure. Please refer to "Definitions and Non-GAAP Financial Measures" for a definition of this term and Appendix D to this release for a reconciliation of this non-GAAP financial measure as used in this release to the most directly comparable financial measure under GAAP.

(2) Revenue days are the total number of calendar days the Company's vessels were in its possession during a period, less the total number of off-hire days during the period associated with events such as major repairs or modifications, dry dockings or special or intermediate surveys. Consequently, revenue days represent the total number of days available for the vessel to earn revenue. Idle days, which are days when the vessel is available to earn revenue but is not employed, are included in revenue days.

(3) Excludes one chartered-in bunker tanker on a time charter-out contract.

(4) Includes Suezmax tankers trading in the Teekay Suezmax RSA and on non-RSA voyage charters.

(5) Includes Aframax and LR2 tankers trading in the Teekay Aframax RSA and on non-RSA voyage charters.

(6) Includes one VLCC tanker, which was acquired by the Company from its 50/50 joint venture in August 2025, which is trading in a pooling arrangement managed by a third-party. For the three months ended September 30, 2025, the vessel earned an average TCE rate of $31,136 per day over 92 revenue days, including the days when the vessel was owned by the joint venture.

Definitions and Non-GAAP Financial Measures

This release includes various financial measures that are non-GAAP financial measures as defined under the rules of the Securities and Exchange Commission (SEC). These non-GAAP financial measures, which include Adjusted Net Income, Adjusted EBITDA, and Net Revenues, are intended to provide additional information and should not be considered substitutes for measures of performance prepared in accordance with GAAP. In addition, these measures do not have standardized definitions across companies, and therefore may not be comparable to similar measures presented by other companies. These non-GAAP measures are used by management, and the Company believes that these supplemental metrics assist investors and other users of its financial reports in comparing financial and operating performance of the Company across reporting periods and with other companies.

Entities under Common Control represent a transfer of a business between entities under common control. As a result, Teekay Tankers' consolidated financial statements prior to the date the interests in these entities were actually acquired by the Company are retroactively adjusted to include the results of these entities during the periods they were under common control of Teekay Corporation Ltd. (Teekay) and had begun operations.

Non-GAAP Financial Measures

Adjusted net income excludes certain items of income or loss from GAAP net income that are typically excluded by securities analysts in their published estimates of the Company’s financial results. The Company believes that certain investors use this information to evaluate the Company’s financial performance, as does management. Please refer to Appendix A of this release for a reconciliation of this non-GAAP financial measure to net income, the most directly comparable GAAP measure reflected in the Company’s consolidated financial statements.

Adjusted EBITDA represents EBITDA (i.e. net income before net income attributable to the Entities under Common Control, interest, taxes, and depreciation and amortization) adjusted to exclude certain items whose timing or amount cannot be reasonably estimated in advance or that are not considered representative of core operating performance. Such adjustments include foreign exchange gains and losses, write-downs of assets, gains and losses on sale of assets, unrealized credit loss adjustments, realized and unrealized gains and losses on marketable securities, unrealized gains and losses on derivative instruments, realized gains or losses on derivative instruments resulting from amendments or terminations of the underlying instruments, equity income or loss and gain on distribution from unconsolidated joint ventures, dividend income from marketable securities and any write-offs and certain other income or expenses. Adjusted EBITDA also excludes realized gains or losses on any interest rate swaps (as management, in assessing the Company's performance, views these gains or losses as an element of interest expense). Adjusted EBITDA is a non-GAAP financial measure used by certain investors and management to measure the operational performance of companies. Please refer to Appendix C of this release for a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP measure reflected in the Company’s consolidated financial statements.

Net revenues represents 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. Since the amount of voyage expenses the Company incurs for a particular charter depends on the type of the charter, the Company includes these costs in net revenues to improve the comparability between periods of reported revenues that are generated by the different types of charters and contracts. The Company principally uses net revenues, a non-GAAP financial measure, because the Company believes it provides more meaningful information about the deployment of the Company's vessels and their performance than does income from operations, the most directly comparable financial measure under GAAP. Please refer to Appendix D of this release for a reconciliation of this non-GAAP financial measure to income from operations, the most directly comparable GAAP measure reflected in the Company’s consolidated financial statements.
