TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) 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 Seapeak LLC (or the Company), which is a limited liability company formed under the laws of the Republic of the Marshall Islands, its wholly-owned or controlled subsidiaries and any variable interest entities (or VIEs) of which it is the primary beneficiary. 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, which were included in the Company's Annual Report on Form 20-F for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission (or SEC) on March 14, 2025. In the opinion of the management of the Company, these unaudited consolidated financial statements reflect all adjustments consisting solely of a normal recurring nature, necessary to present fairly, in all material respects, the Company’s consolidated financial position, results of operations, changes in total equity and cash flows 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. 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 financial statements and accompanying notes. Actual results could differ from those estimates. It is possible that the amounts recorded as derivative liabilities and derivative assets could vary by material amounts prior to their settlement. The Company has made downward revisions to the outlook for its seven steam turbine liquefied natural gas (or LNG) carriers due to a combination of an oversupply of this type of vessel and reduced charterer interest due to their less efficient design. As such, effective January 1, 2025, the Company reduced the estimated useful life of these vessels, the oldest vessels in the Company's LNG fleet, from 35 years to 25 years. Had we continued to depreciate these vessels using an estimated useful life of 35 years instead of 25 years from the beginning of the fiscal period, depreciation and amortization would have decreased and net income would have increased by $4.7 million and $15.6 million for the three and nine months ended September 30, 2025, respectively. 2. Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (or FASB) issued Accounting Standards Update (or ASU) 2023-09 – Income Taxes (Topic 740) Improvements to Income Tax Disclosures (or ASU 2023-09). This ASU enhances the transparency and decision usefulness of income tax disclosures. More specifically, this ASU requires that additional income tax information be disclosed about the jurisdictions in which the Company operates within its income tax rate reconciliation, as well as its disclosure about income taxes paid. This ASU is effective for annual periods beginning after December 15, 2024. The amendments in this ASU are to be applied on a prospective basis. The Company does not expect that adoption of ASU 2023-09 will have a material impact on 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 (or ASU 2024-03). This ASU improves the disclosures about a public business entity’s expenses and addresses requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, selling, general and administrative expenses, and research and development). This ASU is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. The amendments in this ASU are applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this ASU or (2) retrospectively to any or all prior periods presented in the financial statements. The Company does not expect that adoption of ASU 2024-03 will have a material impact on the Company's consolidated financial statements. 3.Fair Value Measurements and Financial Instruments a)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 3a 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 and carrying value of those assets and liabilities that are measured at fair value on a recurring and non-recurring basis, as well as the estimated fair value of the Company’s financial instruments that are not accounted for at fair value on a recurring basis. 10 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) September 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 and cash equivalents and restricted cash (note 13) Level 1 124,612 124,612 187,968 187,968 Short-term investments Level 1 9,200 9,200 — — Derivative instruments (note 11) Interest rate swap agreements – assets Level 2 48,854 48,854 88,025 88,025 Interest rate swap agreements – (liabilities) Level 2 (390) (390) — — Foreign currency contracts - (liabilities) Level 2 (50) (50) (527) (527) Cross currency swap agreements – assets Level 2 1,587 1,587 937 937 Cross currency swap agreements – (liabilities) Level 2 (15,638) (15,638) (47,037) (47,037) Non-recurring: Vessels and equipment (note 14c) Level 3 105,613 105,613 294,631 294,631 Other: Loans to equity-accounted joint ventures (note 7a) (i) 104,381 (i) 99,806 (i) Long-term debt – public (note 8) Level 1 (99,688) (101,901) (174,720) (180,334) Long-term debt – non-public (note 8) Level 2 (777,957) (781,937) (884,819) (886,224) Obligations related to finance leases (note 5) Level 2 (1,836,869) (1,834,956) (1,727,553) (1,715,651) (i) The advances to equity-accounted joint ventures together with the Company’s equity investments in the joint ventures form the net aggregate carrying value of the Company’s interests in the joint ventures in these unaudited consolidated financial statements.

(ii) The changes in credit loss provision of $7.0 million and $20.0 million for the Company's consolidated vessels' direct financing and sales-type leases for the three and nine months ended September 30, 2025, respectively ($(2.3) million and $10.9 million for the three and nine months ended September 30, 2024, respectively), are included in other (expense) income in the Company's consolidated statements of (loss) income. The change in the credit loss provision for the nine months ended September 30, 2025 primarily reflects a decrease in the estimated charter-free valuations for certain types of its LNG carriers at the end of their time-charter contracts which are accounted for as direct financing and sales-type leases in the Company's consolidated balance sheets. These estimated future charter-free values are subject to change based on the underlying LNG shipping market fundamentals. The changes in credit loss provision of $8.8 million and $21.3 million for the three and nine months ended September 30, 2025, respectively, ($(4.0) million and $1.9 million for the three and nine months ended September 30, 2024, respectively), relating to the direct financing and sales-type leases and other within the Company's equity-accounted joint ventures are included in equity income in the Company's consolidated statements of (loss) income. The change in the credit loss provision for the nine months ended September 30, 2025 primarily reflects a decrease in the estimated charter-free valuations for certain types of LNG carriers at the end of their time-charter contracts, which are accounted for as direct financing and sales- type leases within investments in equity-accounted joint ventures in the Company's consolidated balance sheets. The changes in the credit loss provision for the Company's consolidated vessels and the vessels within the Company's equity-accounted joint ventures for the nine months ended September 30, 2025 do not reflect any material change in expectations of the charterers' ability to make their time-charter hire payments as they come due compared to the beginning of the period. 12 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) 4.Segment Reporting The following tables include results for the Company’s segments for the periods presented in these unaudited consolidated financial statements.

These 10 LNG carriers and 10 NGL carriers were sold by the Company to third parties (or Lessors) and leased back under 5.5 to 15-year bareboat charter contracts ending in 2026 through to 2035. At inception of these leases, the weighted-average interest rate implicit in these leases was 6.0% as at September 30, 2025 and December 31, 2024. The bareboat charter contracts are presented as obligations related to finance leases on the Company's consolidated balance sheets. The obligations of the Company's applicable subsidiaries under the bareboat charter contracts for the 10 LNG carriers and 10 NGL carriers are guaranteed by the Company. The guarantee agreements require the Company to maintain minimum levels of tangible net worth and aggregate liquidity, and not to exceed a maximum amount of leverage, for certain of its finance leases. As at September 30, 2025, the Company was in compliance with all covenants in respect of the bareboat charter contracts it guarantees. As at September 30, 2025, the remaining commitments related to the financial liabilities of these 10 LNG carriers and 10 NGL carriers, including the amounts to be paid to repurchase the vessels pursuant to the applicable finance leases, approximated $2.3 billion, including imputed interest of $448.5 million, repayable through 2035, as indicated below: Commitments as at September 30, 2025 Year $ Remainder of 2025 61,550 2026 328,539 2027 396,275 2028 366,637 2029 210,732 Thereafter 921,631 During the first quarter of 2024, the Company refinanced three of its NGL carriers, the Ineos Marlin, the Ineos Inspiration, and the Ineos Independence, by acquiring the vessels from their original Lessors for a total cost of $132.5 million, and then selling the vessels to different Lessors for $204.0 million. As a result of these refinancing transactions, the Company recognized gains totaling $6.2 million on the extinguishment of the original financing arrangements relating to the vessels. These gains are included in other (expense) income in the Company's consolidated statement of (loss) income for the nine months ended September 30, 2024. During June 2024, the Company refinanced the Seapeak Oak LNG carrier by acquiring the vessel from its original Lessor for a total cost of $120.8 million, and then selling the vessel to a different Lessor for $145.3 million. As a result of this refinancing transaction, the Company recognized a loss of $2.7 million on the extinguishment of the original financing arrangement, which is included in other (expense) income in the Company's consolidated statement of (loss) income for the nine months ended September 30, 2024. During the third quarter of 2024, the Company refinanced five of its NGL carriers, the Ineos Intuition, the Ineos Invention, the Ineos Insight, the Ineos Ingenuity, and the Ineos Intrepid, by acquiring the vessels from their original Lessors for a total cost of $169.3 million, and then selling the vessels to different Lessors for $170.4 million. As a result of these refinancing transactions, the Company recognized gains totalling $2.8 million on the extinguishment of the original financing arrangements relating to the vessels. These gains are included in other (expense) income in the Company's consolidated statements of (loss) income for the three and nine months ended September 30, 2024. 14 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) During January 2025, the Company entered into a new financing arrangement for the Marvel Swan LNG carrier whereby it sold the vessel to a third party for $213.0 million and chartered the vessel back for a period of 13 years under a bareboat charter contract. The quarterly charter-hire payments to be made by the Company consist of a fixed amount plus variable amounts based on the Secured Overnight Finance Rate (or SOFR) plus a margin. The Company has an option to repurchase the vessel in July 2032 for $145.7 million. During August 2025 and October 2025, the Company entered into new financing arrangements for the Seapeak Shearwater, the Seapeak Osprey, the Seapeak Kinabalu, the Seapeak Atlas, and the Seapeak Kittiwake LNG carrier newbuildings, which are scheduled for delivery throughout 2027 (see Note 12a). Under these new financing arrangements, the vessels will be sold to a third party upon their delivery for approximately $235.0 million per vessel, subject to conditions of closing. Each of the vessels will be chartered back for a minimum period of 10 years under a bareboat charter contract. The quarterly charter-hire payments to be made by the Company consist of a fixed amount plus variable amounts based on SOFR plus a margin. The Company has an option to repurchase the vessels after 10 years for $129.3 million per vessel. Certain bareboat charter agreements require that the Company maintain ratios of vessel values to the relevant outstanding underlying loan balances. As at September 30, 2025, the Company had five bareboat charter agreements, under which the aggregate outstanding loan balance was $302.0 million, that each requires the Company to maintain minimum vessel-value-to-outstanding-loan obligation balance ratios of 110%, if the vessels are employed under approved charters at such time, or 140%, if the vessels are not employed under approved charters at such time. As at September 30, 2025, the vessel-value-to-outstanding-loan obligation balance ratios were 166%, 163%, 160%, 160% and 138% under approved charters. The vessel values used in calculating these ratios are the appraised values provided by third parties. 6.Revenue The Company’s primary source of revenue is from chartering its vessels to its customers. The Company primarily utilizes two forms of contracts consisting of time-charter contracts and voyage charter contracts. The Company also generates revenue from the management and operation of vessels and the Bahrain LNG import terminal owned by the Company's equity-accounted joint ventures, as well as providing corporate management services to certain of these entities. Such services may include the arrangement of third-party goods and services for the vessel’s owner. For a description of these contracts, see Item 18 – Financial Statements: Note 6 in the Company's audited consolidated financial statements filed with its Annual Report on Form 20-F for the year ended December 31, 2024.

Net Investments in Direct Financing and Sales-Type Leases As at September 30, 2025 and December 31, 2024, the Company had four LNG carriers, excluding the vessels in its equity-accounted joint ventures, that are accounted for as direct financing and sales-type leases. For a description of the Company's LNG carriers accounted for as direct financing leases and sales-type leases at December 31, 2024, see Item 18 – Financial Statements: Note 6 to the Company's audited consolidated financial statements included in its Annual Report on Form 20-F for the year ended December 31, 2024 . As at September 30, 2025, estimated lease payments to be received by the Company related to its direct financing and sales-type leases in each of the next five years were approximately $21.0 million (remainder of 2025), $82.3 million (2026), $83.6 million (2027), $78.9 million (2028), $50.6 million (2029) and an aggregate of $562.0 million thereafter. Two leases are expected to end in 2028, one lease is scheduled to end in 2039 and the remaining lease is scheduled to end in 2046. Operating Leases As at September 30, 2025, the minimum scheduled future rentals to be received by the Company in each of the next five years for the lease and non-lease elements related to charters that were accounted for as operating leases are approximately $112.5 million (remainder of 2025), $385.6 million (2026), $228.1 million (2027), $176.3 million (2028), and $149.0 million (2029).

Therefore, the minimum scheduled future rentals on operating leases should not be construed to reflect total charter hire revenues for any of these five years. Contract Liabilities As at September 30, 2025, the Company had $33.9 million of advanced payments recognized as contract liabilities included in unearned revenue (December 31, 2024 – $37.1 million, September 30, 2024 – $32.4 million and December 31, 2023 – $43.6 million).

The Company entered into cross currency rate swaps, to swap all interest and principal payments of the bonds into U.S. Dollars, with the interest payments fixed at 6.37% and the transfer of principal fixed at $117.0 million upon maturity in exchange for NOK 1.0 billion (see Note 11). The weighted-average interest rates for the Company’s long-term debt outstanding excluding the effect of related interest rate swaps as at September 30, 2025 and December 31, 2024 were 6.44% and 7.06%, respectively. The Company uses swaps to economically hedge certain of its floating-rate debt (see Note 11). The weighted-average interest rates including the effect of related interest rate swaps were 5.50% and 5.65% as at September 30, 2025 and December 31, 2024, respectively. Non-U.S.-denominated debt is revalued at the end of each period using the then-prevailing U.S. Dollar exchange rate. Due primarily to the revaluation of the Company’s NOK-denominated bonds and euro-denominated cash, and the change in the valuation of the Company’s cross currency swaps, the Company incurred foreign exchange losses of $0.9 million and $3.7 million for the three and nine months ended September 30, 2025, respectively ($4.8 million and $3.5 million for the three and nine months ended September 30, 2024, respectively). 17 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) The aggregate annual long-term debt principal repayments required under the Company's revolving credit facility, loans and bonds subsequent to September 30, 2025 are $20.8 million (remainder of 2025), $316.4 million (2026), $321.6 million (2027), $54.7 million (2028), $45.5 million (2029) and $124.0 million (thereafter). Certain loan agreements require that (a) the Company maintain minimum levels of tangible net worth and aggregate liquidity, (b) the Company maintain certain ratios of vessel values related to the relevant outstanding loan principal balance, (c) the Company not exceed a maximum amount of leverage, and (d) certain of the Company’s subsidiaries maintain restricted cash deposits. As at September 30, 2025, the Company had three credit facilities with an aggregate outstanding loan balance of $299.2 million that require it to maintain minimum vessel-value-to-outstanding-loan-principal-balance ratios of 110%, 120%, and 120%, which as at September 30, 2025, were 198%, 193%, and 194%, respectively. The vessel values used in calculating these ratios are the appraised values provided by third parties, where available, or prepared by the Company based on second-hand sale and purchase market data. Since vessel values can be volatile, the Company’s estimates of market value may not be indicative of either the current or future prices that could be obtained if the Company sold any of the vessels. The Company’s ship-owning subsidiaries may not, among other things, pay dividends or distributions if the Company's subsidiaries are in default under their term loans and, in addition, one of the term loans in the RasGas II Joint Venture requires it to satisfy a minimum vessel value to outstanding loan principal balance ratio to pay dividends. As at September 30, 2025, the Company was in compliance with all covenants relating to the Company’s credit facilities and other long-term debt. 9.Income Tax Recovery (Expense) The components of the provision for income tax recovery (expense) are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2025 2024 2025 2024 $ $ $ $ Current 669 (895) (1,266) (1,063) Deferred 312 214 570 1,061 Income tax recovery (expense) 981 (681) (696) (2) Included in the Company's current income tax recovery (expense) are provisions for uncertain tax positions relating to freight taxes. The Company does not presently anticipate that its provisions for these uncertain tax positions will significantly increase in the next 12 months; however, this is dependent on the jurisdictions in which vessel trading activity occurs. The Company reviews its freight tax obligations on a regular basis and may update its assessment of its tax positions based on available information at that time. Such information may include additional legal advice as to the applicability of freight taxes in relevant jurisdictions. Freight tax regulations are subject to change and interpretation; therefore, the amounts recorded by the Company may change accordingly. 10.Related Party Transactions a) The following table and related footnotes provide information about certain of the Company's related party transactions for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2025 2024 2025 2024 $ $ $ $ Voyage revenues (i)(ii) 32,171 31,702 96,803 96,453 Equity income (iii) 609 609 1,808 1,814 (i) In September 2018, the Company’s Floating Storage Unit, the Seapeak Bahrain, commenced its 21-year charter contract with the Bahrain LNG Joint Venture, in which the Company has a 30% ownership interest. Voyage revenues from the charter of the Seapeak Bahrain to the Bahrain LNG Joint Venture for the three and nine months ended September 30, 2025 amounted to $7.1 million and $21.8 million, respectively ($7.7 million and $23.6 million for the three and nine months ended September 30, 2024, respectively). In addition, the Company has an operation and maintenance contract with the Bahrain LNG Joint Venture relating to the LNG regasification terminal in Bahrain. Fees recognized in relation to the operation and maintenance contract from the Bahrain LNG Joint Venture for the three and nine months ended September 30, 2025 were $4.1 million and $12.6 million, respectively ($4.1 million and $13.1 million for the three and nine months ended September 30, 2024, respectively), and are included in voyage revenues in the Company's consolidated statements of (loss) income. (ii) The Company provides ship management and corporate services to certain of its equity-accounted joint ventures that own and operate LNG carriers on long-term charters. In addition, the Company is reimbursed for costs incurred by the Company for its seafarers operating these LNG carriers. During the three and nine months ended September 30, 2025, the Company earned management fees and cost reimbursements pursuant to these management agreements of $21.0 million and $62.4 million, respectively ($19.9 million and $59.8 million for the three and nine months ended September 30, 2024, respectively), which are included in voyage revenues in the Company's consolidated statements of (loss) income. (iii) During the three and nine months ended September 30, 2025 and 2024, the Company charged fees of $0.6 million and $1.8 million to the Yamal LNG Joint Venture, in which the Company has a 50% ownership interest, relating to the successful bid process for the construction and chartering of six ARC7 LNG carriers. The fees are reflected in equity income in the Company’s consolidated statements of (loss) income. 18 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) b)As at September 30, 2025 and December 31, 2024, non-interest-bearing amounts due from affiliates totaled $13.9 million and $19.7 million, respectively, and non-interest-bearing amounts due to affiliates totaled $13.0 million and $6.7 million, respectively. These amounts due to/from affiliates are unsecured and have no fixed repayment terms. c)For other transactions with the Company's equity-accounted joint ventures not disclosed above, please refer to Note 7. 11.Derivative Instruments and Hedging Activities The Company uses derivative instruments in accordance with its overall risk management policy. Foreign Exchange Risk From time to time, the Company economically hedges portions of its forecasted expenditures denominated in foreign currencies and portions of its foreign currency cash balances with foreign currency forward contracts. As at September 30, 2025, the Company was committed to the following foreign currency forward contracts: Contract Amount in Foreign Currency Average Contract Rate(i) Fair Value / Carrying Amount of Asset (Liability) $ Expected Maturity of Notional Amounts Currency 2025 $ 2026 $ Economic hedges of forecasted expenditures British Pound Sterling 4,500 0.7716 218 1,896 3,936 Canadian Dollar 8,700 1.3824 (1) 1,749 4,545 Euro 2,500 0.8568 17 2,918 — 234 6,563 8,481 Economic hedges of foreign currency cash balances Euro 72,853 0.8535 (284) 85,354 — (i) Average contractual exchange rate represents the contracted amount of foreign currency one U.S. Dollar will buy. The Company entered into cross currency swaps concurrently with the issuance of its NOK-denominated senior unsecured bonds (see Note 8), and pursuant to these swaps, the Company receives the principal amount in NOK on maturity dates of the swaps in exchange for payments of a fixed U.S. Dollar amount. In addition, the cross currency swaps exchange a receipt of floating interest in NOK based on NIBOR plus a margin for a payment of U.S. Dollar fixed interest. The purpose of the cross currency swaps is to economically hedge the foreign currency exposure on the payment of interest and principal of the Company’s NOK-denominated bonds due in 2026, and to economically hedge the interest rate exposure. The following table reflects information relating to the cross currency swaps as at September 30, 2025. Floating Rate Receivable Principal Amount NOK Principal Amount $ Reference Rate Margin Fixed Rate Payable Fair Value / Carrying Amount of Asset (Liability) $ Weighted- Average Remaining Term (Years) 1,000,000 117,000 NIBOR 4.90% 6.37% (14,050) 1.1 Interest Rate Risk The Company enters into interest rate swaps which exchange a receipt of floating interest for a payment of fixed interest to reduce the Company’s exposure to interest rate variability on certain of its outstanding floating-rate debt. 19 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) As at September 30, 2025, the Company was committed to the following interest rate swap agreements: Interest Rate Index Principal Amount $ Fair Value / Carrying Amount of Asset (Liability) $ Weighted- Average Remaining Term (years) Fixed Interest Rate (i) U.S. Dollar-denominated interest rate swaps (ii) SOFR 635,117 16,058 2.5 1.7% U.S. Dollar-denominated interest rate swaps (ii)(iii) SOFR 206,224 6,728 3.5 3.4% U.S. Dollar-denominated interest rate swaps (iv)(v)(vi) SOFR 64,635 19,827 0.6 3.0% U.S. Dollar-denominated interest rate swap (ii)(v)(vi) SOFR 34,472 5,851 1.9 3.2% 48,464 (i) Excludes an additional amount consisting of the margins and the credit adjustment spreads the Company pays on its floating-rate term loans, which, at September 30, 2025, ranged from 2.00% to 3.45%. (ii) Principal amount reduces quarterly. (iii) These interest rate swaps are subject to mandatory early termination in June 2027 and September 2029, whereby the swaps will be settled based on their fair value at that time. (iv) Principal amount reduces monthly. (v) Forward-starting interest rate swaps with effective start dates ranging from November 2025 to June 2026. (vi) These interest rate swaps are subject to mandatory early termination in 2026 and in 2027 whereby the swaps will be settled based on their fair value at that time. As at September 30, 2025, the Company had multiple interest rate swaps, cross currency swaps and foreign currency forward contracts with the same counterparty that are subject to the same master agreement. Each of these master agreements provides for the net settlement of all swaps subject to that master agreement through a single payment in the event of default or termination of any one swap. The fair value of these derivative instruments is presented on a gross basis in the Company’s consolidated balance sheets. As at September 30, 2025, these derivative instruments constituted an aggregate fair value asset of $48.8 million (December 31, 2024 – $88.0 million) and an aggregate fair value liability of $2.8 million (December 31, 2024 – $34.4 million). As at September 30, 2025, the Company had $3.8 million (December 31, 2024 – $19.5 million) of cash on deposit as security for swap liabilities under certain master agreements. The deposit is presented in restricted cash – current and long-term on the Company's consolidated balance sheets. Credit Risk The Company is exposed to credit loss in the event of non-performance by the counterparties to its derivative instruments. In order to minimize counterparty risk, the Company only enters into derivative transactions with counterparties that are rated A- or better by Standard & Poor’s or A3 or better by Moody’s at the time of the transactions. In addition, to the extent practical, derivative instruments are entered into with different counterparties to reduce concentration risk. The following table presents the classification and fair value amounts of derivative instruments (none of which are designated as cash flow hedges), segregated by type of contract, on the Company’s consolidated balance sheets. Accounts receivable $ Current portion of derivative assets $ Derivative assets $ Current portion of derivative liabilities $ Derivative liabilities $ As at September 30, 2025 Interest rate swap agreements 1,724 29,681 17,449 — 390 Foreign currency forward contracts — — — 50 — Cross currency swap agreements 210 1,377 — — 15,638 1,934 31,058 17,449 50 16,028 As at December 31, 2024 Interest rate swap agreements 2,070 35,042 50,913 — — Foreign currency forward contracts — — — 527 — Cross currency swap agreements 295 642 — 21,756 25,281 2,365 35,684 50,913 22,283 25,281 20 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) Realized and unrealized gains (losses) relating to non-designated interest rate swap agreements and foreign currency forward contracts are recognized in earnings and reported in realized and unrealized (loss) gain on non-designated derivative instruments in the Company’s consolidated statements of (loss) income.

As at September 30, 2025, expenditures incurred under these newbuilding contracts totaled $275.5 million and the estimated remaining expenditures to be incurred are $26.6 million (remainder of 2025), $243.4 million (2026), and $638.8 million (2027). The Company intends to finance substantially all of the remaining estimated pre-delivery expenditures with borrowings under two U.S. Dollar-denominated term loans maturing in 2027. In addition, the final construction installments due on delivery and the repayment of the two U.S. Dollar- denominated term loans maturing in 2027 will be financed with 10-year sale and leaseback financing arrangements, where the Samsung LNG Carrier Newbuildings will be sold to a third party upon their delivery for approximately $235.0 million per vessel (see Note 5). (b) In March 2023, the Exmar LPG Joint Venture entered into contracts with Hyundai Mipo Dockyard Co., Ltd. (or HMD) for the construction of two 45,000-cubic meter ammonia capable dual-fueled LPG carriers with scheduled deliveries in 2026. In March 2024, the Exmar LPG Joint Venture entered into contracts with HMD for the construction of two additional 45,000-cubic meter ammonia capable dual-fueled LPG carriers with scheduled deliveries in late-2026. The Company's proportionate share of the total fully built-up cost of these four vessels is approximately $173.7 million. As at September 30, 2025, the Company's proportionate share of expenditures incurred under these newbuilding contracts totaled $52.6 million and the Company's proportionate share of estimated remaining expenditures to be incurred are $10.3 million (remainder of 2025) and $110.8 million (2026). In January 2025, the Exmar LPG Joint Venture entered into contracts with Avance Gas Aries Ltd. for the assumption by the joint venture of shipbuilding contracts for the construction of four 40,000-cubic meter dual-fueled LPG carriers. These vessels are being constructed by Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd., with scheduled deliveries in late-2025 and 2026. The Company's proportionate share of the total fully built-up cost of these four vessels is approximately $151.5 million. As at September 30, 2025, the Company's proportionate share of expenditures incurred under these newbuilding contracts totaled $67.2 million and the Company's proportionate share of estimated remaining expenditures to be incurred are $25.4 million (remainder of 2025) and $58.9 million (2026). (c) The Company has a 30% ownership interest in the Bahrain LNG Joint Venture which has an LNG receiving and regasification terminal in Bahrain. In October 2025, the Bahrain LNG Joint Venture agreed on the remaining final construction installment payment and charges related to a dispute with the Bahrain LNG terminal contractor. The Bahrain LNG Joint Venture intends to finance the final construction installment payment and charges through its existing undrawn financing, its existing liquidity, and potential cash contributions from the shareholders (of which the Company’s proportionate share is estimated to be up to $5.9 million). (d) The Company owns 70% of Seapeak BLT Corporation (or the Tangguh Joint Venture), which is a party to operating leases whereby the Tangguh Joint Venture is leasing the Tangguh Hiri and Tangguh Sago LNG carriers (or the Tangguh LNG Carriers) to a third party, which is in turn leasing the vessels back to the joint venture. The Company’s minimum charter hire payments to be paid and received under these leases are described in more detail in Item 18 – Financial Statements: Note 14e to the Company’s audited consolidated financial statements filed with its Annual Report on Form 20-F for the year ended December 31, 2024. Under the terms of the leasing arrangement for the Tangguh LNG Carriers, whereby the Tangguh Joint Venture is the lessee, the lessor claims tax depreciation on its lease of these vessels. As is typical in these types of leasing arrangements, tax and change of law risks are assumed by the lessee. Lease payments under the lease arrangements are based on certain tax and financial assumptions at the commencement of the leases. If an assumption proves to be incorrect, the lessor is entitled to increase the lease payments to maintain its agreed after-tax margin. As at September 30, 2025, the carrying amount of this estimated tax indemnification obligation relating to the leasing arrangement through the Tangguh Joint Venture was $3.4 million (December 31, 2024 – $3.8 million) and was included as part of other long-term liabilities in the consolidated balance sheets of the Company. (e) Effective January 1, 2024, emissions emitted by the maritime industry have been integrated in the European Union Emissions Trading System (or EU ETS) and are being phased in over a three-year period. Emissions for voyages to or from Europe or within Europe included within the scope of EU ETS were based on 40% during 2024 and are based on 70% during 2025 and will be 100% in 2026. The Company is obligated to submit Emissions Allowances (or EUAs) for all vessels under its operational management on an annual basis prior to September 30th of each year. Each EUA represents a carbon credit that grants the holder the right to emit one tonne of CO2 equivalent under the EU ETS. In September 2025, the Company remitted 250,090 EUAs, which were related to emissions for voyages during the year ended December 31, 2024. For a description of the Company's environmental emissions' accounting policy, see Item 18 – Financial Statements: Note 1 to the Company’s audited consolidated financial statements filed with its Annual Report on Form 20-F for the year ended December 31, 2024. 22 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) The following table presents the classification and carrying amounts of assets and liabilities related to EU ETS on the Company’s consolidated balance sheets: Amounts due from affiliates $ Other current assets $ Accrued liabilities and other $ As at September 30, 2025 Amounts due from equity-accounted investees 14,807 — — Amounts due from charterers — 7,675 — EUAs held by the Company — 4,890 — Obligation to submit EUAs — — 28,072 14,807 12,565 28,072 As at December 31, 2024 Amounts due from equity-accounted investees 11,524 — — Amounts due from charterers — 6,404 — EUAs held by the Company — 70 — Obligation to submit EUAs — — 18,356 11,524 6,474 18,356 (f) Management is required to assess whether the Company will have sufficient liquidity to continue as a going concern for the one-year period following the issuance of its unaudited consolidated financial statements. The Company had a working capital deficit of $231.1 million as at September 30, 2025. This working capital deficit includes $113.9 million related to scheduled maturities and repayments of long-term debt in the 12 months following September 30, 2025. Based on the Company’s liquidity at the date these unaudited consolidated financial statements were issued, the liquidity it expects to generate from operations over the following year, and the cash distributions it expects to receive from its equity-accounted joint ventures, the Company estimates that it will have sufficient liquidity to continue as a going concern for at least the one-year period following the issuance of these unaudited consolidated financial statements. 13.Supplemental Cash Flow Information The following is a tabular reconciliation of the Company's cash, cash equivalents and restricted cash balances for the periods presented in the Company's consolidated statements of cash flows. September 30, 2025 December 31, 2024 September 30, 2024 December 31, 2023 $ $ $ $ Cash and cash equivalents 103,732 153,726 196,884 168,409 Restricted cash – current — 9,210 2,380 2,910 Restricted cash – long-term 20,880 25,032 19,700 13,075 124,612 187,968 218,964 184,394 The Company maintains restricted cash deposits relating to certain term loans, collateral for derivatives (see Note 11), vessels held for sale, obligations related to finance leases and amounts received from charterers to be used only for dry-docking expenditures and emergency repairs. 23 Table of Contents SEAPEAK LLC AND SUBSIDIARIES NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (all tabular amounts stated in thousands of U.S. Dollars, unless otherwise indicated) 14.(Write-down) and Gain on Sales of Vessels a) In February 2024, the Company sold the Seapeak Napa multi-gas carrier for net proceeds of $10.4 million, resulting in a gain on sale of $0.5 million, which is included in (write-down) and gain on sales of vessels for the nine months ended September 30, 2024 in the Company's consolidated statement of (loss) income. In March 2024, the Company sold the Seapeak Cathinka multi-gas carrier for net proceeds of $6.5 million, resulting in a gain on sale of $0.2 million, which is included in (write-down) and gain on sales of vessels for the nine months ended September 30, 2024 in the Company's consolidated statement of (loss) income. In April 2024, the Company sold the Seapeak Camilla for net proceeds of $6.7 million, resulting in a gain on sale of $0.3 million, which is included in (write-down) and gain on sales of vessels for the nine months ended September 30, 2024 in the Company's consolidated statement of (loss) income. b) In August 2024, the Company sold the Seapeak Pan multi-gas carrier for net proceeds of $6.5 million, resulting in a gain on sale of $3.4 million, which is included in (write-down) and gain on sales of vessels for the three and nine months ended September 30, 2024 in the Company's consolidated statements of (loss) income. c) As at September 30, 2025, the Company's LNG segment included seven steam turbine LNG carriers, the oldest vessels in our LNG fleet. To reduce the Company's operating costs, three of these vessels were placed in lay-up in early 2025. As at September 30, 2025, these vessels were presented as held for sale in the Company's consolidated balance sheet. The 20-year charters for three of the Company’s seven steam turbine LNG carriers, consisting of the RasGas II Joint Venture (or RasGas II) vessels, are scheduled to expire during October 2026 to February 2027. Steam turbine LNG carriers are currently facing acute market pressure amid weak demand and a record number of such vessels are currently inactive. The outlook for these vessels is not expected to significantly improve by late-2026 and early-2027. Therefore, it is expected that the RasGas II vessels will be sold, unless a suitable charter can be found prior to the expiration of their existing charters. As a result, in September 2025, the carrying values of these vessels were written down to their estimated fair values. The total impairment charge of $61.8 million is included in (write-down) and gain on sales of vessels for the three and nine months ended September 30, 2025 in the Company's consolidated statements of (loss) income. The vessels were written down to their estimated fair values using a discounted cash flow approach based on the vessels operating to age 20 years on their existing long-term fixed-rate charter contracts and subsequent sale at a price which is based on recent transactions for LNG carriers of a similar age. 15.Total Capital Common Unit Distributions On February 27, 2025, the Company declared and paid a cash distribution of $1.0005 per common unit, totaling $100.0 million, to its sole common unitholder, Stonepeak Limestone Holdings L.P. (or Stonepeak). On March 25, 2024, the Company declared and paid a cash distribution of $2.0010 per common unit, totaling $200.0 million, to Stonepeak. 16.Restructuring Charges During the three and nine months ended September 30, 2025, the Company recognized restructuring charges of $1.5 million and $20.7 million, respectively. The restructuring charges primarily relate to severance costs resulting from the dismissal of substantially all of the Company’s Spanish seafarers. This severance follows the Company’s decision to restructure the operations of the four steam turbine LNG carriers, which comprise its Spanish fleet, due to the adverse market conditions affecting steam turbine LNG carriers. 17.Subsequent Events On October 23, 2025, the Company entered into a U.S. Dollar-denominated term loan agreement, which allows for borrowings of up to $258.5 million. The term loan is collateralized by first-priority mortgages on the Seapeak Kinabalu, the Seapeak Atlas and the Seapeak Kittiwake LNG carrier newbuildings. Interest payments are based on SOFR plus a margin of 2.0%. The term loan is repayable at maturity in 2027. On October 31, 2025, the Company borrowed $103.4 million from this term loan. 24 SEAPEAK LLC AND SUBSIDIARIES SEPTEMBER 30, 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 with "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. Included in our Annual Report on Form 20-F is important information about items that you should consider when evaluating our results, information about the types of contracts we enter into and certain non-GAAP measures we utilize to measure our performance. Unless otherwise indicated, references in this Report to “we,” “us” and “our” and similar terms refer to Seapeak LLC and its subsidiaries. OVERVIEW Seapeak LLC is an international provider of marine transportation services focusing on liquefied natural gas (or LNG) and natural gas liquid (or NGL). Our primary strategy focuses on servicing customers through our fleet of vessels under medium to long-term, fixed-rate charters. We may evaluate and enter into adjacent liquefied gas markets, renewable markets, and other maritime opportunities. In executing our strategy, we may engage in vessel or business acquisitions or enter into joint ventures and partnerships with companies that provide increased access to emerging opportunities from global expansion of the LNG and NGL sectors. SIGNIFICANT DEVELOPMENTS IN 2025 Steam Turbine LNG Carriers As at September 30, 2025, our LNG segment included seven steam turbine LNG carriers, the oldest vessels in our LNG fleet. To reduce our operating costs, three of these vessels were placed in lay-up in early 2025. As at September 30, 2025, these three vessels were classified as held for sale in our September 30, 2025 consolidated balance sheet. In addition, we have recognized $20.7 million of restructuring charges during the nine months ended September 30, 2025, which primarily relate to severance costs resulting from the dismissal of substantially all of our Spanish seafarers. This severance follows our decision to restructure the operations of the four steam turbine LNG carriers, which comprise our Spanish fleet, due to the adverse market conditions affecting steam turbine LNG carriers. The 20-year charters for three of our seven steam turbine LNG carriers, consisting of the RasGas II Joint Venture (or RasGas II) vessels, are scheduled to expire during October 2026 to February 2027. Steam turbine LNG carriers are currently facing acute market pressure amid weak demand and thus a record number of such vessels are currently inactive. The outlook for these vessels is not expected to significantly improve by late-2026 and early-2027. Therefore, it is expected that the RasGas II vessels will be sold, unless a suitable charter can be found prior to the expiration of their existing charters. As a result, in September 2025 we have reduced our estimate of their useful lives from 25 years to 20 years. In addition, the carrying values of these vessels were written down to their estimated fair values at September 30, 2025, resulting in an impairment charge of $61.8 million. MALT LNG Carrier Charter Contracts Two of the six LNG carriers in our 52%-owned MALT Joint Venture, the Seapeak Marib and Seapeak Arwa, were chartered-out to Yemen LNG Company Limited (or YLNG) under long-term charter contracts. However, due to the political unrest in Yemen, YLNG decided to temporarily close operation of its LNG plant in Yemen in 2015. As a result, commencing January 1, 2016, the MALT Joint Venture agreed to successive deferral arrangements with YLNG pursuant to which a portion of the charter payments was deferred. In March 2025, the MALT Joint Venture entered into a third suspension agreement (or the Third Suspension Agreement) with YLNG to further extend the charter deferral period for the Seapeak Marib and the Seapeak Arwa for up to an additional three years until March and April 2028, respectively. Should the LNG plant in Yemen resume operations during the term of the Third Suspension Agreement, YLNG will be required to repay the applicable deferred amounts plus interest in installments over a specified time period. However, there are no assurances if or when the LNG plant will resume operations, or if YLNG will repay, or be able to repay, all or any portion of the deferred amounts. As was the case with the previous suspension agreements, pursuant to the Third Suspension Agreement, the MALT Joint Venture is permitted to directly charter the Seapeak Marib and the Seapeak Arwa for its own account to third parties. 25 Russia-Ukraine War The ongoing Russia-Ukraine war has disrupted energy markets and supply chains, has resulted in various sanctions on Russian entities individuals, and sectors, and has caused volatility in global energy markets. The United States has been in discussions with Russia and Ukraine aimed at ending the war since the first quarter of 2025. While much uncertainty remains regarding the global impact and remaining duration of the war, and the impact of any additional sanctions that may be imposed on Russia and its trading partners, it is possible that continued hostilities between Russia and Ukraine and any actions taken by the U.S. administration or by other nations in response to those hostilities could adversely affect our business, financial condition, results of operations and cash flows. In October 2025, the EU announced that effective January 1, 2027, there will be a ban on imports of Russian LNG into the EU. It is possible that third parties with which we have charter contracts or business arrangements may be impacted directly or indirectly by the war, which could adversely affect our operations and financial condition. To date, we have not experienced any material adverse financial impact as a result of the Russia-Ukraine war. Geopolitical and Economic Uncertainty The U.S. administration continues to negotiate and implement new or increased tariffs on foreign imports, which may result in retaliatory tariffs being levied on certain U.S. goods and commodities and potential 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-Connected Ships In early 2025, the Office of the U.S. Trade Representative announced that port docking fees will apply to vessels connected with China and that dock at U.S. ports. Commencing on October 14, 2025, Chinese vessel owners and Chinese vessel operators were subject to fees starting at $50 per net ton, and non-Chinese operators using Chinese-built vessels are subject to fees starting at $18 per net ton, in each case, subject to annual fee increases but up to a cap of five visits per year per vessel. As a result, vessels connected with China (either via Chinese ownership/ operations or by virtue of being built in China) and transporting NGL to and/or from the United States are subject to significant fees, potentially disrupting the competitive landscape within our industry and global NGL carrier routes. At this time, we are unable to determine with certainty the impact these additional fees will have on us, our operations or our industry, as there are numerous exemptions available (including if a non- Chinese operator that uses a Chinese-built vessel arrives to a U.S. port in ballast condition, and a fee exemption for LNG vessels). A total of 14 of our vessels, including two vessels in which we have a 30% ownership interest and two vessels in which we have a 20% ownership interest, are Chinese-built. In addition, in January 2025, our 50%-owned Exmar LPG Joint Venture entered into contracts with Avance Gas Aries Ltd. to assume its shipbuilding contracts for the construction of four new 40,000-cubic meter LPG carriers being constructed by Chinese shipbuilder, Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. The Exmar LPG Joint Venture also entered into contracts for the in-chartering of four new 40,000-cubic meter LPG carriers and two new 48,000-cubic meter LPG carriers in August 2023 and July 2024, respectively, that are currently being constructed by Chinese shipbuilder, Jiangsu Yangzi-Mitsui Shipbuilding Co., Ltd. In October 2025, China also announced retaliatory port fees on vessels connected with the U.S. and that dock at Chinese ports. The fee, which will also be effective from October 14, 2025, starts at RMB 400 per net ton (approximately $56 per net ton), and is subject to a cap of five visits per calendar year. At this time, we are unable to determine with certainty the impact these additional fees will have on us, our operations or our industry. In November 2025, the U.S. announced that the U.S. and China agreed on a reciprocal one-year suspension of their respective port fees. Accordingly, at this time, we do not expect our business to be materially impacted by such proposed port fees. Other Fleet Developments We have three 52%-owned LNG carriers that recently completed their long-term charter contracts and have been operating on short-term charter contracts since their redeliveries to us. Additionally, we have one wholly-owned LNG carrier which is expected to complete its long-term charter contract in December 2025. LNG project delays have caused a near-term oversupply of LNG carriers. As a result, our results for 2025 and beyond may be negatively impacted to the extent that there are periods within 2025 or subsequent years that we have LNG carriers without charter contracts or we have rechartered our LNG carriers at rates lower than they earned on their prior charter contracts. RESULTS OF OPERATIONS The following includes a comparison of the components of our results of operations for the three and nine months ended September 30, 2025 as compared to the same periods of the prior year. 26 Liquefied Natural Gas Segment As at September 30, 2025, our LNG segment fleet included 50 LNG carriers (including five LNG carriers under construction), and one LNG regasification terminal in Bahrain, in which our interests ranged from 20% to 100%. The following table compares our LNG segment’s operating results, revenue days, calendar-ship-days and utilization for the three and nine months ended September 30, 2025 and 2024, and compares its net voyage revenues (which is a non-GAAP financial measure) for the three and nine months ended September 30, 2025 and 2024 to (loss) income from vessel operations, the most directly comparable GAAP financial measure. With the exception of equity income, all data in this table only includes 21 LNG carriers that are accounted for under the consolidation method of accounting for the three and nine months ended September 30, 2025 (2024 – 20 LNG carriers) and the ship management and corporate services we provide to certain of our equity-accounted joint ventures. A comparison of the results from vessels and assets accounted for under the equity method is described later in this section under "Equity Income".

(ii) Includes direct general and administrative expenses and indirect general and administrative expenses (allocated to each segment based on estimated use of resources). See the discussion under “Other Operating Results” below. For the nine months ended September 30, 2025, total calendar-ship-days of the LNG segment were 5,733 compared to 5,480 days for the same period of the prior year. The increase in total calendar-ship-days is primarily due to the purchase of the Marvel Swan in October 2024. Net Voyage Revenues. Net voyage revenues decreased by $11.2 million and $35.4 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily as a result of: • decreases of $15.6 million and $48.1 million for the three and nine months ended September 30, 2025 due to the lay-up of the Seapeak Asia (formerly Seapeak Catalunya), the Seapeak Hispania, and the Seapeak Madrid LNG carriers during the nine months ended September 30, 2025 and lower short-term charter rates earned following the scheduled completion of their previous charter contracts; and • decreases of $4.2 million and $14.3 million for the three and nine months ended September 30, 2025 primarily due to lower charter rates earned by the Seapeak Vancouver LNG carrier following the scheduled completion of its previous charter contract in March 2025; partially offset by: • increases of $7.7 million and $22.9 million for the three and nine months ended September 30, 2025 due to the purchase of the Marvel Swan LNG carrier in October 2024; • increases of $1.1 million and $2.2 million for the three and nine months ended September 30, 2025 due to higher reimbursement of seafarers' costs (offset in vessel operating expenses) and ship management fees from certain of our equity-accounted joint ventures during 2025; and • an increase of $1.4 million for the nine months ended September 30, 2025 due to fewer off-hire days for unscheduled repairs on certain of our LNG carriers during 2025. Vessel Operating Expenses. Vessel operating expenses increased by $0.5 million and $4.9 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily due to: • increases of $1.6 million and $4.3 million for the three and nine months ended September 30, 2025 due to the purchase of the Marvel Swan LNG carrier in October 2024; • increases of $1.1 million and $2.0 million for the three and nine months ended September 30, 2025 due to higher reimbursable seafarers' costs related to vessels operating in certain of our equity-accounted joint ventures during 2025 (offset in voyage revenues); and • an increase of $0.9 million for the nine months ended September 30, 2025 due to the timing of repairs and maintenance on the Bahrain LNG terminal and certain of our LNG carriers; partially offset by: • decreases of $1.9 million and $3.2 million for the three and nine months ended September 30, 2025 due to the lay-up of three of our steam turbine LNG carriers since early 2025; and • a decrease of $1.1 million for the three months ended September 30, 2025 due to the timing of repairs and maintenance on the Bahrain LNG terminal and certain of our LNG carriers. 28 Depreciation and Amortization. Depreciation and amortization decreased by $1.9 million and $4.5 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily due to: • decreases of $2.9 million and $7.2 million for the three and nine months ended September 30, 2025 due to the write-down of our seven steam turbine LNG carriers during the fourth quarter of 2024; partially offset by the reduction in the estimated useful life of these LNG carriers effective January 1, 2025; and • decreases of $0.8 million and $2.4 million for the three and nine months ended September 30, 2025 due to the acquisition cost of the 20- year time-charter contract for the Seapeak Madrid being fully amortized upon its scheduled completion in December 2024; partially offset by: • increases of $1.8 million and $5.2 million for the three and nine months ended September 30, 2025 due to the purchase of the Marvel Swan LNG carrier in October 2024. Write-down of vessels. Write-down of vessels was $61.8 million for the three and nine months ended September 30, 2025 and relates to the write-down of three of our steam turbine LNG carriers to their estimated fair values in September 2025 as a result of changes in our expectations of their future opportunities. Equity Income. Equity income decreased by $26.3 million and $28.4 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year. The changes in equity income include decreases of $12.8 million and $19.4 million related to changes in our unrealized credit loss provisions recorded in certain of our equity-accounted joint ventures, primarily due to a decrease in the estimated charter-free vessel fair values for vessels servicing time-charter contracts accounted for as direct financing or sales-type leases for the three and nine months ended September 30, 2025 and a decrease of $2.6 million due to unrealized losses on non-designated derivative instruments for the nine months ended September 30, 2025, compared to unrealized gains during the same period of the prior year, primarily due to changes in long-term forward benchmark interest rates. The decrease in equity income for the three months ended September 30, 2025 was partially offset by an increase of $5.5 million due to lower unrealized losses on non-designated derivative instruments for the three months ended September 30, 2025, compared to the same period of the prior year. Excluding the changes in unrealized credit loss provisions and unrealized (losses) gains on non-designated derivative instruments, equity income decreased by $19.0 million and $6.4 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily due to: • MALT LNG Joint Venture: decreases of $10.6 million and $15.5 million for the three and nine months ended September 30, 2025, primarily due to lower charter rates earned by certain LNG carriers and the vessels being temporarily idle between short-term charter contracts during 2025. • Bahrain LNG Joint Venture: decreases of $7.4 million and $0.3 million for the three and nine months ended September 30, 2025, primarily due to increases in legal expenses and interest costs associated with the settlement of a dispute with the Bahrain LNG terminal contractor in October 2025, partially offset by decreases in Bahrain LNG terminal repair costs during 2025. • Yamal LNG Joint Venture: decrease of $1.0 million for the three months ended September 30, 2025, primarily due to unrealized foreign exchange losses due to the period-end revaluation of Euro cash deposits for financial reporting purposes into U.S. Dollars and higher depreciation expense due to the completion of the first scheduled dry dockings of certain LNG carriers in the second half of 2024. partially offset by: • Yamal LNG Joint Venture: increase of $10.1 million for the nine months ended September 30, 2025, primarily due to unrealized foreign exchange gains due to the period-end revaluation of Euro cash deposits for financial reporting purposes into U.S. Dollars; partially offset by higher depreciation expense due to the completion of the first scheduled dry dockings of certain LNG carriers in the second half of 2024. Natural Gas Liquid Segment As at September 30, 2025, our NGL segment fleet, which consists of LPG, ethane and multi-gas carriers, included 44 NGL carriers, in which our interests ranged from 25% to 100% (including seven time chartered-in NGL carriers, eight NGL carriers under construction and six time chartered-in NGL carriers under construction). The following table compares our NGL segment’s operating results, revenue days, calendar-ship-days and utilization for the three and nine months ended September 30, 2025 and 2024, and compares its net voyage revenues (which is a non-GAAP financial measure) for the three and nine months ended September 30, 2025 and 2024 to income from vessel operations, the most directly comparable GAAP financial measure. With the exception of equity income, all data in this table only includes an average of 10 wholly-owned NGL carriers that are accounted for under the consolidation method of accounting for the three and nine months ended September 30, 2025 (2024 – 12 wholly- owned NGL carriers and six chartered-in NGL carriers). A comparison of the results from vessels and assets accounted for under the equity method are described below under "Equity Income". 29 (in thousands of U.S. Dollars, except for days and percentages) Three Months Ended September 30, Change % Change 2025 2024 Voyage revenues 28,939 35,848 (6,909) (19.3) Voyage expenses (540) (1,419) 879 (61.9) Net voyage revenues(i) 28,399 34,429 (6,030) (17.5) Vessel operating expenses (8,614) (11,836) 3,222 (27.2) Time-charter hire expenses — (2,108) 2,108 (100.0) Depreciation and amortization (8,006) (7,920) (86) 1.1 General and administrative expenses(ii) (706) (1,360) 654 (48.1) Gain on sales of vessels — 3,368 (3,368) (100.0) Income from vessel operations 11,073 14,573 (3,500) (24.0) Equity income 6,555 2,722 3,833 140.8 Operating Data: Calendar-ship-days (B) 920 1,501 (581) (38.7) Less: Scheduled dry-docking days 21 — 21 100.0 Unscheduled off-hire and idle days — 33 (33) (100.0) Revenue days (A) 899 1,468 (569) (38.8) Utilization (A)/(B) 97.7% 97.8% (in thousands of U.S. Dollars, except for days and percentages) Nine Months Ended September 30, Change % Change 2025 2024 Voyage revenues 85,513 110,075 (24,562) (22.3) Voyage expenses (842) (6,468) 5,626 (87.0) Net voyage revenues(i) 84,671 103,607 (18,936) (18.3) Vessel operating expenses (25,418) (36,093) 10,675 (29.6) Time-charter hire expenses — (6,409) 6,409 (100.0) Depreciation and amortization (23,770) (23,286) (484) 2.1 General and administrative expenses(ii) (2,505) (4,355) 1,850 (42.5) Gain on sales of vessels — 4,339 (4,339) (100.0) Income from vessel operations 32,978 37,803 (4,825) (12.8) Equity income 18,610 21,532 (2,922) (13.6) Operating Data: Calendar-ship-days (B) 2,730 4,781 (2,051) (42.9) Less: Scheduled dry-docking days 60 46 14 30.4 Unscheduled off-hire and idle days 25 128 (103) (80.5) Revenue days (A) 2,645 4,607 (1,962) (42.6) Utilization (A)/(B) 96.9% 96.4% (i) This is a non-GAAP financial measure; for more information about this measure, including a reconciliation to the most directly comparable financial measure calculated and presented in accordance with GAAP, please read “Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Non-GAAP Financial Measures”. (ii) Includes direct general and administrative expenses and indirect general and administrative expenses (allocated to each segment based on estimated use of resources). See the discussion under “Other Operating Results” below. For the nine months ended September 30, 2025, total calendar-ship-days of the NGL segment were 2,730 compared to 4,781 days for the same period of the prior year. The decrease in total calendar-ship-days is due to the redelivery of six chartered-in NGL carriers to their owners in December 2024 and the sales of the Seapeak Napa, the Seapeak Cathinka, the Seapeak Camilla and the Seapeak Pan, in February 2024, March 2024, April 2024 and August 2024, respectively. 30 Net Voyage Revenues. Net voyage revenues decreased by $6.0 million and $18.9 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily due to: • decreases of $4.8 million and $15.5 million for the three and nine months ended September 30, 2025 due to the scheduled redelivery of six time chartered-in NGL carriers to their owners in December 2024; • a decrease of $3.1 million for the nine months ended September 30, 2025 due to the sales of our multi-gas carriers, the Seapeak Napa, the Seapeak Cathinka, the Seapeak Camilla, and the Seapeak Pan during 2024; and • a decrease of $0.8 million for the three months ended September 30, 2025 due to an increase in scheduled dry dockings of certain of our NGL carriers during the third quarter of 2025. Vessel Operating Expenses. Vessel operating expenses decreased by $3.2 million and $10.7 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily due to: • decreases of $3.1 million and $8.9 million for the three and nine months ended September 30, 2025 due to the scheduled redelivery of six chartered-in NGL carriers to their owners in December 2024; and • a decrease of $2.5 million for the nine months ended September 30, 2025 due to the sales of the Seapeak Napa, the Seapeak Cathinka, the Seapeak Camilla and the Seapeak Pan during 2024; partially offset by: • an increase of $0.9 million for the nine months ended September 30, 2025 due to higher seafarers' costs on certain of our NGL carriers primarily due to the timing and location of crew changes during the first half of 2025. Time-Charter Hire Expenses. Time-charter hire expenses decreased by $2.1 million and $6.4 million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, due to the scheduled redelivery of six chartered-in LPG carriers to their owners in December 2024. Gain on Sales of Vessels. Gain on sales of vessels was $3.4 million and $4.3 million for three and nine months ended September 30, 2024 and relates to the sales of the Seapeak Napa, the Seapeak Cathinka, Seapeak Camilla, and the Seapeak Pan in February 2024, March 2024, April 2024 and August 2024, respectively. Equity Income. Equity income from the Exmar LPG Joint Venture increased (decreased) by $3.8 million and $(2.9) million for the three and nine months ended September 30, 2025, compared to the same periods of the prior year, primarily due to: • increases of $2.6 million and $5.5 million for the three and nine months ended September 30, 2025 due to an increase in earnings related to the deliveries of the Champagny and the Courchevel LPG carriers during 2025; and • an increase of $2.3 million for the three months ended September 30, 2025 due to lower unrealized losses on non-designated derivative instruments, compared to the same period of the prior year primarily due to changes in long-term forward benchmark interest rates during these periods; partially offset by: • a decrease of $5.1 million for the nine months ended September 30, 2025 due to a $6.5 million gain recognized on the sale of the Severin Schulte LPG carrier during the second quarter of 2024 and $0.9 million due to an impairment of the right of use asset associated with the in-chartered Severin Schulte LPG carrier during the first quarter of 2025, as a result of a reduction in our estimated future hire rates compared to a $2.3 million gain recognized on the sale of the Sophie Schulte LPG carrier during the second quarter of 2025; • decreases of $0.6 million and $1.7 million for the three and nine months ended September 30, 2025 due to the net impact of sale- leasebacks of two in-chartered LPG carriers at higher rates; and • a decrease of $0.8 million for the nine months ended September 30, 2025 due to unrealized losses on non-designated derivative instruments, compared to unrealized gains during the same period of the prior year primarily due to changes in long-term forward benchmark interest rates during these periods. 31 Other Operating Results The following tables compares our other operating results for the three and nine months ended September 30, 2025 and 2024: Three Months Ended September 30, Change % Change (in thousands of U.S. Dollars) 2025 2024 General and administrative expenses (13,549) (7,007) (6,542) 93.4 Restructuring charges (1,460) — (1,460) 100.0 Interest expense (41,353) (44,620) 3,267 (7.3) Interest income 3,059 3,724 (665) (17.9) Realized and unrealized loss on non- designated derivative instruments (1,261) (28,065) 26,804 (95.5) Foreign currency exchange loss (924) (4,789) 3,865 (80.7) Other (expense) income (7,480) 5,599 (13,079) (233.6) Income tax recovery (expense) 981 (681) 1,662 (244.1) Other comprehensive loss (2,359) (18,678) 16,319 (87.4) Nine Months Ended September 30, Change % Change (in thousands of U.S. Dollars) 2025 2024 General and administrative expenses (27,953) (22,459) (5,494) 24.5 Restructuring charges (20,724) — (20,724) 100.0 Interest expense (126,125) (133,824) 7,699 (5.8) Interest income 9,311 10,590 (1,279) (12.1) Realized and unrealized (loss) gain on non- designated derivative instruments (26,476) 3,465 (29,941) (864.1) Foreign currency exchange loss (3,737) (3,485) (252) 7.2 Other expense (21,469) (3,943) (17,526) 444.5 Income tax expense (696) (2) (694) 34,700.0 Other comprehensive loss (16,266) (9,150) (7,116) 77.8 General and Administrative Expenses. General and administrative expenses were $13.5 million and $28.0 million for the three and nine months ended September 30, 2025, as compared to $7.0 million and $22.5 million for the same periods of the prior year. The increases for the three and nine months ended September 30, 2025 were primarily due to a discretionary compensation payment to directors and management approved by our sole common shareholder. Restructuring charges. Restructuring charges were $1.5 million and $20.7 million for the three and nine months ended September 30, 2025 and primarily relate to severance costs resulting from the dismissal of substantially all of our Spanish seafarers. This severance follows our decision to restructure the operations of the four steam turbine LNG carriers, which comprise our Spanish fleet, due to the adverse market conditions affecting steam turbine LNG carriers. Interest Expense. Interest expense was $41.4 million and $126.1 million for the three and nine months ended September 30, 2025, as compared to $44.6 million and $133.8 million for the same periods of the prior year. Interest expense primarily reflects interest incurred on our long-term debt and obligations related to finance leases. The decreases were primarily due to lower debt balances as a result of scheduled repayments and the lower utilization of our revolving credit facility, and lower floating interest rates during 2025; partially offset by the financing of the Marvel Swan LNG carrier during the first quarter of 2025 and the refinancing of certain of our vessels during 2024. Realized and Unrealized (Loss) Gain on Non-designated Derivative Instruments. We have entered into interest rate swaps which exchange a receipt of floating interest for a payment of fixed interest to reduce exposure to interest rate variability on certain of our outstanding U.S. Dollar- denominated and Euro-denominated floating rate debt. Our interest rate swaps typically require settlements every three months and the receipt of floating interest is based on the prevailing SOFR rate at the beginning of the settlement period. "Item 1 – Financial Statements: Note 11 – Derivative Instruments and Hedging Activities" provides details of our current derivative positions and a breakdown of realized and unrealized gains (losses) relating to these non-designated interest rate swap agreements for the three and nine months ended September 30, 2025 and 2024. Realized gains (losses) during a period reflect prevailing SOFR rates that are higher (lower) than the average fixed rates of our interest rate swaps. Unrealized gains (losses) will primarily reflect an increase (decrease) in the long-term SOFR yield curve during each relevant period. Realized and unrealized (losses) gains on non-designated derivative instruments were $(1.3) million and $(26.5) million for the three and nine months ended September 30, 2025, as compared to $(28.1) million and $3.5 million for the same periods of the prior year, primarily due to changes in the prevailing and forward SOFR rates during these periods. 32 Foreign Currency Exchange Loss. Foreign currency exchange loss was $0.9 million and $3.7 million for the three and nine months ended September 30, 2025, as compared to $4.8 million and $3.5 million for the same periods of the prior year. These foreign currency exchange losses were primarily due to the relevant period-end revaluation of our NOK-denominated debt and, for the three and nine months ended September 30, 2024, our Euro-denominated term loan for financial reporting purposes into U.S. Dollars, net of the realized and unrealized gains and losses on our cross currency swaps. Gains and losses on NOK-denominated and Euro-denominated monetary liabilities reflect a stronger (gains) or weaker (losses) U.S. Dollar against the NOK and Euro on the date of revaluation or settlement compared to the rate in effect at the beginning of the period. Our cross currency swaps economically hedge all of the foreign currency and interest rate exposure on our NOK- denominated debt. Our Euro-denominated debt was used to purchase two vessels that were on long-term charters which entitled us to payment of charter-hire in Euros. As such, our Euro-denominated debt was repaid with these fixed Euro charter hire receipts and consequently our Euro currency exposure was limited by this arrangement. As at September 30, 2025, we have no exposure to Euro-denominated debt as it matured in December 2024. Other (expense) income. Other (expense) income was $(7.5) million and $(21.5) million for the three and nine months ended September 30, 2025, as compared to $5.6 million and $(3.9) million for the same periods of the prior year. The change in other (expense) income was primarily due to increases of $10.1 million and $10.3 million in unrealized credit loss provisions for the three and nine months ended September 30, 2025, as compared to the same periods of the prior year, primarily due to decreases in the estimated charter-free vessel fair values for vessels servicing time-charter contracts accounted for as direct financing or sales-type leases, and their impact on our expectation of the value of such vessels upon completion of their existing charter contracts. Other (expense) income also includes $2.8 million and $6.3 million in financing extinguishment gains recognized upon the repurchases of certain NGL carriers during the three and nine months ended September 30, 2024. Income tax recovery (expense). Income tax recovery (expense) was $1.0 million and $(0.7) million for the three and nine months ended September 30, 2025, as compared to $(0.7) million and a nominal amount for the same periods of the prior year. The change in income tax recovery (expense) for the three months ended September 30, 2025 was primarily due to lower freight tax estimates compared to the same period of the prior year. The change in income tax recovery (expense) for the nine months ended September 30, 2025 was primarily due to estimated income taxes owing related to the transfer of certain of our NGL operations from France to Denmark and changes in current and deferred tax balances related to the timing of deductions in our Tangguh Joint Venture, in which we have a 70% ownership interest during 2025; partially offset by lower freight tax estimates during 2025. Other Comprehensive Loss. Other comprehensive loss was $(2.4) million and $(16.3) million for the three and nine months ended September 30, 2025, as compared to $(18.7) million and $(9.2) million for the same periods of the prior year. The changes in other comprehensive loss results were primarily due to changes in the forward SOFR benchmark interest rates, where the results of our joint ventures reflect the use of hedge accounting. The decrease in other comprehensive loss for the three months ended September 30, 2025 was primarily due to unrealized gains on our interest rate swap agreements, compared to unrealized losses for the same period of the prior year. The increase in other comprehensive loss for the nine months ended September 30, 2025 was primarily due to unrealized losses on our interest rate swap agreements, compared to unrealized gains for the same period of the prior year; partially offset by lower realized gains on our interest rate swap agreements, compared to the same period of the prior year. Liquidity and Capital Resources Sources and Uses of Capital For a description of our sources and uses of capital, please read “Item 5 – Operating and Financial Review and Prospects – Liquidity and Capital Resources” in our Annual Report on Form 20-F for the year ended December 31, 2024. Our sources of funds include borrowings from debt facilities and borrowings from obligations related to finance leases, which are described in "Item 1 – Financial Statements: Note 8 – Long-Term Debt and Note 5 – Chartered-in Vessels". We also guarantee our proportionate share of certain loan facilities and obligations on interest rate swaps for certain of our equity-accounted joint ventures. As at September 30, 2025, this proportionate share, based on the aggregate principal amount of the loan facilities and fair value of the interest rate swaps, was $812.2 million. As at September 30, 2025, our equity-accounted joint ventures were in compliance with all covenants relating to these loan facilities that we guarantee. Certain of our credit facilities and obligations related to finance leases require us to maintain financial covenants. If we do not meet these financial covenants, the lender or lessor may limit our ability to borrow additional funds under our credit facilities and accelerate the repayment of our revolving credit facility, term loans and bonds, and obligations related to finance leases, which would have a significant impact on our short-term liquidity requirements. The terms of and compliance with these financial covenants are described in further detail in "Item 1 – Financial Statements: Note 5 – Chartered-in Vessels and Note 8 – Long-Term Debt" included in this Report. Certain of our debt facilities and obligations related to finance leases require us to make interest payments based on NIBOR or SOFR. Significant increases in interest rates could adversely affect results of operations and our ability to service our debt; however, as part of our strategy to minimize financial risk, we use interest rate swaps and cross currency swaps to reduce our exposure to market risk from changes in interest rates. Our current positions are described in further detail in "Item 1 – Financial Statements: Note 11 – Derivative Instruments and Hedging Activities" included in this Report and the extent of our exposure to changes in interest rates is described in further detail in "Item 11 – Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 20-F for the year ended December 31, 2024. 33 Liquidity Our total liquidity, which consists of cash, cash equivalents, short-term investments, and undrawn credit facilities, was $252.9 million as at September 30, 2025, compared to $338.7 million as at December 31, 2024, a decrease of $85.8 million. This decrease was due to a $45.0 million increase in the amounts drawn on our revolving credit facility (which allows for borrowings of up to $350.0 million) and a decrease in cash and cash equivalents of $50.0 million; partially offset by an increase in short-term investments of $9.2 million (as detailed in "Item 1 – Financial Statements: Unaudited Consolidated Statements of Cash Flows" included in this Report, excluding a decrease in restricted cash of $13.4 million). The following table summarizes our contractual obligations as at September 30, 2025, excluding those of our equity-accounted joint ventures. We expect that our liquidity at September 30, 2025, combined with the operating cash flows we expect to generate from customer contracts in place at September 30, 2025, and the cash distributions we expect to receive from our equity-accounted joint ventures, will be sufficient to pay our obligations coming due in the next 12 months following September 30, 2025. Our ability to pay our obligations, and to refinance our long- term debt and finance leases coming due subsequent to September 30, 2025, will depend on, among other things, our ability to continue to service our long-term charter contracts, our financial condition and the condition of credit markets in the months leading up to the maturity dates. We may expand the size of our fleet through the acquisition of new or second-hand vessels or through the construction of additional new vessels. Our ability to continue to expand the size of our fleet over the long-term is dependent upon our ability to generate operating cash flow, obtain long-term bank borrowings, sale-leaseback financings and other debt, as well as our ability to raise debt or equity financing.

(ii) Includes, in addition to lease payments, amounts to purchase the leased vessels at the end of their respective lease terms. Where applicable, accelerated timing of repayments may be required if the Company is not in compliance with certain covenants under its lease agreements. (iii) We have corresponding leases whereby we are the lessor and expect to receive approximately $74.4 million under these leases from the remainder of 2025 to 2029. (iv) During November 2022, we entered into contracts with Samsung Heavy Industries Co., Ltd. for the construction of five 174,000-cubic meter M-type, Electronically Controlled, Gas Admission propulsion LNG carriers (or the Samsung LNG Carrier Newbuildings), which are scheduled for deliveries throughout 2027. We intend to finance substantially all of the remaining estimated pre-delivery expenditures with borrowings under two U.S. Dollar- denominated term loans maturing in 2027. In addition, the final construction installments due on delivery and the repayment of the two U.S. Dollar- denominated term loans maturing in 2027 will be financed with 10-year sale and leaseback financing arrangements, where the Samsung LNG Carrier Newbuildings will be sold to a third party upon their delivery for approximately $235.0 million per vessel and leased back to us. In addition to the commitments in the table above, our equity-accounted joint ventures have commitments to fund newbuilding and other construction contract costs all of which are non-recourse to us. See "Item 1 – Financial Statements: Note 12 – Commitments and Contingencies" included in this Report. Critical Accounting Estimates and Risk Factors 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 materially differ from our assumptions and estimates, and such differences could be material. Accounting estimates and assumptions discussed in "Item 5 – Operating and Financial Review and Prospects – Critical Accounting Estimates" of our Annual Report on Form 20-F for the year ended December 31, 2024, are those that we consider to be the most critical to an understanding of our financial statements, because they inherently involve significant judgments and uncertainties. For a further description of our critical accounting policies, please read "Item 5 – Operating and Financial Review and Prospects – Critical Accounting Estimates" and "Item 18 – Financial Statements: Note 1 – Summary of Significant Accounting Policies" in our Annual Report on Form 20-F for the year ended December 31, 2024. Our three RasGas II Joint Venture steam turbine LNG carriers are expected to complete their 20-year fixed rate charters in late-2026 and early-2027. We and our joint venture partner will assess opportunities for these vessels throughout the remainder of 2025 and 2026. Because the sale of these vessels after they complete their existing charters is a probable outcome, we have reduced our estimate of their useful lives from 25 years to 20 years and the carrying values of these vessels were written down to their estimated fair values at September 30, 2025, resulting in an impairment charge of $61.8 million. There have been no other significant changes in accounting estimates and assumptions from those discussed in our 2024 Annual Report on Form 20-F. 34 In addition to the other information set forth in this Report on Form 6-K, you should carefully consider the risk factors discussed in Part I, “Item 3. Key Information – Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2024, which could materially affect our business, financial condition or results of operations. Non-GAAP Financial Measures Net Voyage Revenues Net voyage revenues is a non-GAAP financial measure. Consistent with general practice in the shipping industry, we use net voyage revenues 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 shipowner pays these expenses, we include voyage expenses in net voyage revenues. Some voyage expenses are fixed, and the remainder can be estimated. If we, as the shipowner, pay the voyage expenses, we typically pass on to our customers the approximate amount of these expenses by charging higher rates under the contract or billing the expenses to them. As a result, although voyage revenues from different types of contracts may vary, the net voyage revenues are generally comparable across the different types of contracts. We principally use net voyage revenues because it provides more meaningful information to us than voyage revenues. Net voyage revenues is also widely used by investors and analysts in the shipping industry for comparing financial performance between companies and to industry averages. How we use net voyage revenues and the reasons for such use may be unique to the shipping industry. Given that net voyage revenues is a measure which deducts certain operating expenses from revenue, this metric may be more commonly viewed as an alternative measure of gross profit. Viewed in this context, (loss) income from vessel operations would be the most directly comparable GAAP financial measure, and net voyage revenues has been defined as (loss) income from vessel operations before restructuring charges, write-down and (gain) on sales of vessels, general and administrative expenses, depreciation and amortization, time-charter hire expenses and vessel operating expenses. The following table reconciles net voyage revenues with income from vessel operations: LNG Segment NGL Segment Three Months Ended September 30, Three Months Ended September 30, (in thousands of U.S. Dollars) 2025 2024 2025 2024 (Loss) income from vessel operations (20,065) 60,175 11,073 14,573 Restructuring charges 1,460 — — — Write-down and (gain) on sales of vessels 61,792 — — (3,368) General and administrative expenses 12,843 5,647 706 1,360 Depreciation and amortization 25,606 27,458 8,006 7,920 Time-charter hire expenses — — — 2,108 Vessel operating expenses 46,246 45,782 8,614 11,836 Net voyage revenues 127,882 139,062 28,399 34,429 LNG Segment NGL Segment Nine Months Ended September 30, Nine Months Ended September 30, (in thousands of U.S. Dollars) 2025 2024 2025 2024 Income from vessel operations 58,436 184,098 32,978 37,803 Restructuring charges 20,724 — — — Write-down and (gain) on sales of vessels 61,792 — — (4,339) General and administrative expenses 25,448 18,104 2,505 4,355 Depreciation and amortization 77,769 82,295 23,770 23,286 Time-charter hire expenses — — — 6,409 Vessel operating expenses 139,441 134,519 25,418 36,093 Net voyage revenues 383,610 419,016 84,671 103,607 35 FORWARD-LOOKING STATEMENTS This Report on Form 6-K for the three and nine months ended September 30, 2025 contains certain forward-looking statements (as such term is defined in Section 27A of the Securities Act of 1933 as amended, and Section 21E of the Securities Exchange Act of 1934, as amended) concerning future events and our operations, performance and financial condition, including, in particular, statements regarding: • our liquidity needs, including our anticipated funds and sources of financing for liquidity and working capital needs and the sufficiency of cash flows and our expectation that we will have sufficient liquidity for at least a one-year period; • the expected timing of deliveries, costs and related financing relating to our LNG carrier newbuildings and the Exmar LPG Joint Venture's LPG carrier newbuildings; • our expectations as to the useful lives of our vessels, including those of our equity-accounted joint ventures, and the revenue that will be generated from these vessels; • expected exposure to interest rate volatility; • the potential expansion of the size of our fleet through the acquisition of new or second-hand vessels or through the construction of additional new vessels; • expected cash distributions from our equity-accounted joint ventures; • expected interest payments; • the possibility of future resumption of the LNG plant in Yemen operated by YLNG and the repayment of deferred hire amounts from YLNG on our two 52%-owned vessels, the Seapeak Marib and Seapeak Arwa; • general domestic and international political conditions and geopolitical conflicts, including the impact of the Russia-Ukraine war on the economy, our industry and our business; • the impact on our results for 2025 and beyond by any LNG carriers without charter contracts or LNG carriers rechartered at reduced rates; • future sales or chartering opportunities for the RasGas II JV steam turbine LNG carriers following expiration of their existing vessel charter contracts; • the impact of tariffs, and recent U.S and Chinese port docking fees on the economy, our industry and our business; • the impact of recent accounting pronouncements on our consolidated financial statements and related disclosures; and • expectations regarding the impact of uncertain tax positions and changes in corporate tax rates.
