Derek Lowe, Chief Executive Officer and Chief Financial Officer of KNOT Offshore Partners LP, stated, “We are pleased to report another strong performance in Q2 2025, marked by safe operation at full utilization from scheduled operations, close to 97% utilization when including drydockings, consistent revenue and operating income generation, and material progress in securing additional charter coverage for our fleet.

As of the date of this release and including contractual updates since June 30, 2025, we have now secured 100% of charter coverage for the second half of 2025 after allowing for scheduled dry dockings, and approximately 89% for 2026. We remain focused on further strengthening our fleetwide charter coverage and seizing those periodic opportunities that exist to re-charter vessels in the current tight market environment.

In Brazil, the main offshore oil market where we operate, new production start-ups in shuttle tanker-serviced pre-salt fields have continued to outpace Petrobras’s already-aggressive baseline schedule. As a result, the world’s biggest shuttle tanker market is both growing and materially tightening. The North Sea, our secondary geography, has also established some positive momentum as projects ramp up production in both the UK North Sea and, most significantly, the Barents Sea. While less dynamic than is the case in Brazil, these positive developments in the wider North Sea region are a welcome and notable change after a protracted period of relatively slack shuttle tanker demand.

Driven by these dynamics, we continue to believe that growth of offshore oil production in shuttle tanker-serviced fields across both Brazil and the North Sea is on track to outpace shuttle tanker supply growth throughout the coming years. We are aware of newbuild shuttle tanker orders, including seven for Knutsen NYK, all of which are scheduled for delivery over 2025-2028. We anticipate that all these new orders are backed by charters to clients in Brazil, and see this as a sign of confidence in the medium-to-long term demand for the global shuttle tanker fleet. Particularly when considered in the context of the increasing numbers of shuttle tankers reaching or exceeding typical retirement age, as well as yard capacity constraints limiting material new orders into at least 2028, we anticipate that these newbuild deliveries will be readily absorbed by the expanding market for shuttle tankers.

As the largest owner and operator of shuttle tankers (together with our sponsor, Knutsen NYK), we believe we are well positioned to benefit from such an improving charter market. We remain focused on generating certainty and stability of cash flows from long-term employment with high-quality counterparties, both through continued chartering and through the consummation of accretive dropdown transactions. We are also pleased to have reached an important milestone early in the third quarter, with our cashflow, financial strength, and overall outlook having improved to the extent that we felt it prudent to initiate a common unit buyback program, which is enabling us to take advantage of what we believe to be a pronounced value opportunity. We are confident that continued operational performance and the successful execution of our strategy in an improving market environment can increase our cash flow generation, strengthen our forward visibility, and create sustainable unitholder value in the quarters and years ahead.

Financial Results Overview

Results for Q2 2025 (compared to those for the three months ended March 31, 2025 (“Q1 2025”)) included:

Revenues of $87.1 million in Q2 2025 ($84.0 million in Q1 2025), with the increase due to higher utilization of the fleet, driven by the full effect of the sale of Dan Sabia and the addition of Live Knutsen to the fleet, and generally improved terms of contracts on certain vessels.

There was no gain from disposal of vessel in Q2 2025 ($1.3 million in Q1 2025).
Vessel operating expenses of $33.0 million in Q2 2025 ($30.6 million in Q1 2025), with the increase due primarily to bunker fuel expenses and higher maintenance and upgrading cost related to vessels in dry dock.
--- ---
Depreciation of $29.4 million in Q2 2025 ($28.8 million in Q1 2025).
--- ---
General and administrative expenses of $1.6 million in Q2 2025 ($1.8 million in Q1 2025).
--- ---

Operating income consequently of $22.2 million in Q2 2025 ($23.4 million in Q1 2025).
Interest expense of $15.3 million in Q2 2025 ($14.9 million in Q1 2025)
--- ---
Realized (i.e. cash) gain on derivative instruments of $2.5 million in Q2 2025 (gain of $3.1 million in Q1 2025), and unrealized (i.e. non-cash) loss of $2.9 million in Q2 2025 (unrealized loss of $4.5 million in Q1 2025). Together, there was a realized and unrealized loss on derivative instruments of $0.4 million in Q2 2025 (loss of $1.3 million in Q1 2025).
--- ---
Net income consequently of $6.8 million in Q2 2025 ($7.6 million in Q1 2025).
--- ---

By comparison with the three months ended June 30, 2024 (“Q2 2024”), results for Q2 2025 included:

An increase of $20.9 million in operating income (to $22.2 million in Q2 2025 from operating income of $1.3 million in Q2 2024), driven primarily by the $16.4 million non-cash impairment of Dan Cisne and Dan Sabia as of June 30, 2024, whereas no impairment was recorded in Q2 2025. Higher utilization of the fleet and greater charter revenues also contributed to the increase. Adjusting for the impact of the impairment in Q2 2024, operating income increased by $4.5 million in Q2 2025.
An increase of $1.2 million in finance expense (to finance expense of $15.2 million in Q2 2025 from finance expense of $14.0 million in Q2 2024), due primarily to an unrealized and realized loss on derivative instruments in Q2 2025 compared to an unrealized and realized gain in Q2 2024.
--- ---
An increase of $19.7 million in net income (to a net income of $6.8 million in Q2 2025 from a net loss of $12.9 million in Q2 2024).

Financing and Liquidity

As of June 30, 2025, the Partnership had $104.8 million in available liquidity, which was comprised of cash and cash equivalents of $66.3 million and $38.5 million of capacity under its revolving credit facilities. The Partnership’s revolving credit facilities mature in November 2025 and, August 2027 respectively.

The Partnership’s total interest-bearing obligations outstanding as of June 30, 2025 were $918.6 million ($914.5 million net of debt issuance costs). These did not include the Daqing Facility described below, which was assumed on July 2, 2025. The average margin paid on the Partnership’s outstanding debt during Q2 2025 was approximately 2.23% over SOFR. These obligations are repayable as follows:

**** Sale & **** Period
(U.S. Dollars in thousands) Leaseback repayment Balloon repayment Total
Remainder of 2025 $ 7,357 $ 44,660 $ 81,077 $ 133,094
2026 15,060 74,461 284,203 373,724
2027 15,751 37,034 95,098 147,883
2028 16,520 19,080 78,824 114,424
2029 17,232 6,154 23,386
2030 and thereafter 85,370 40,704 126,074
Total $ 157,290 $ 222,093 $ 539,202 $ 918,585

As of June 30, 2025, the Partnership had entered into various interest rate swap agreements for a total notional amount outstanding of $421.2 million, to hedge against the interest rate risks of its variable rate borrowings. As of June 30, 2025, the Partnership receives interest based on SOFR and pays a weighted average interest rate of 2.54% under its interest rate swap agreements, which have an average maturity of approximately 1.58 years. The Partnership does not apply hedge accounting for derivative instruments, and its financial results are impacted by changes in the market value of such financial instruments.

As of June 30, 2025, the Partnership’s net exposure to floating interest rate fluctuations was approximately $273.8 million based on total interest-bearing contractual obligations of $918.6 million, less the Raquel Knutsen and Torill Knutsen sale and leaseback facilities of $157.3 million, less interest rate swaps of $421.2 million, and less cash and cash equivalents of $66.3 million.

The Daqing Facility became one of the Partnership’s debt obligations upon closing of the acquisition of the Daqing Knutsen on July 2, 2025, and is therefore not included in the Partnership’s outstanding debt as of June 30, 2025. The Daqing Facility is repayable in quarterly installments with a final payment due at maturity on June 13, 2027 of $62.3 million, which includes the balloon payment and last quarterly installment. The facility bears interest at a rate per annum equal to SOFR plus a margin of 1.94%. In connection with this acquisition, the Partnership and KNOT Shuttle Tankers AS became the sole guarantors. The facility is secured by a mortgage on the Daqing Knutsen.

On August 15, 2025, the Partnership closed the refinancing of the first of its two $25 million revolving credit facilities, with the facility being rolled over with NTT TC Leasing Co, Ltd... The new facility will mature in August 2027, bears interest at a rate per annum equal to SOFR plus a margin of 2.3%, and has a commitment fee on any undrawn portion of the facility that varies based on the aggregate borrowing amount: 0.70% per annum for borrowings up to $10 million, 0.60% per annum for borrowings between $10 million and $20 million, and 0.50% per annum for borrowings exceeding $20 million. The commercial terms of the facility are substantially unchanged from the facility entered into in August 2023 with NTT TC Leasing Co, Ltd.. The Partnership is continuing discussions and negotiations with the lender under its second $25 million revolving credit facility, which will mature in November 2025.

On September 16, 2025, the Partnership, through its wholly-owned subsidiary, Knutsen Shuttle Tankers 34 AS, which owns the Tove Knutsen, sold the Tove Knutsen to, and leased her back from, a Japanese-based lessor, for a lease period of 10 years. The gross sale price was $100 million and a portion of the proceeds were used to repay the outstanding loan secured by the vessel and to settle the related interest rate swaps. The bareboat rate under the lease consists of a fixed element per day and there is a fixed-price purchase obligation at maturity. Following closing and after repayment of the 5

loan and settlement of the interest rate swaps, the Partnership realized net proceeds of approximately $32 million after fees and expenses.

The Partnership has commenced discussions and negotiations with its lending group and other institutions and advisors concerning the refinancing of its senior secured loan facility secured by the Synnove Knutsen, which matures in October 2025 with a repayment due at that time of $72.26 million.

Given the negotiations that are already underway and given the Partnership’s history of successfully obtaining financing or refinancing its debt, management believes that it will be able to conclude a refinancing of these facilities on similar terms (including that no re-leverage is required) prior to their respective maturities. However, no assurance can be given that such facilities will be timely refinanced on acceptable terms.

Common Unit Repurchase Program

On July 2, 2025, the Board authorized the repurchase of up to an aggregate of $10 million of the Partnership’s outstanding common units over the subsequent 12 months (the “Program”).

Purchases of common units under the Program will be at prevailing prices on the open market or in privately negotiated transactions, and will be subject to available liquidity, market conditions, credit agreement restrictions, applicable legal requirements, contractual obligations and other factors. The Program does not require the Partnership to acquire any specific number of common units. The Partnership intends to purchase common units under the Program opportunistically with available funds, while maintaining sufficient liquidity to fund its capital needs. The Program may be suspended from time to time, modified, extended or discontinued by Board at any time. As of September 25, 2025, the Partnership had paid $1.64 million to repurchase an aggregate of 226,374 common units at an average price of $7.24 per common unit. Common units repurchased under the Program are being cancelled.

Assets Owned by Knutsen NYK

Pursuant to the omnibus agreement the Partnership entered into with Knutsen NYK at the time of its initial public offering, the Partnership has the option to acquire from Knutsen NYK any offshore shuttle tankers that Knutsen NYK acquires or owns that are employed under charters for periods of five or more years.

While the Partnership continues to believe that key components of its strategy and value proposition are accretive investment in the fleet and a long-term, sustainable distribution, there can be no assurance that the Partnership will acquire any additional vessels from Knutsen NYK. Given the relationship between the Partnership and Knutsen NYK, any such acquisition would be subject to the approval of the Conflicts Committee of the Partnership’s Board of Directors.

As of the date of this release, Knutsen NYK owns, or has ordered, the following vessels and has entered into the following charters:

1. In July 2022, Frida Knutsen was delivered to Knutsen NYK from the yard in Korea and commenced in December 2022 on a seven-year time charter contract with Eni for operation in North Sea. The charterer has options to extend the charter by up to a further three years.
2. In August 2022, Sindre Knutsen was delivered to Knutsen NYK from the yard in Korea and commenced in September 2023 on a five-year time charter contract with Eni for operation in the North Sea. The charterer has options to extend the charter by up to a further five years.
--- ---
3. In November 2022, Knutsen NYK entered into a new fifteen-year time charter contract with Petrobras for a vessel to be constructed and which will operate in Brazil, where the charterer has an option to extend the charter by up to five further years. The vessel, named Eli Knutsen, has been built in China and is being delivered imminently.
--- ---

4. In February 2024, Knutsen NYK entered into a new ten-year time charter contract with Petrobras for each of three vessels to be constructed and which will operate in Brazil, where the charterer has an option to extend each charter by up to five further years. The vessels will be built in China and are expected to be delivered over 2026 - 2027.
5. In August 2024, Knutsen NYK entered into a new seven-year time charter contract with Petrorio for a vessel to be constructed and which will operate in Brazil, where the charterer has an option to extend the charter by up to eight further years. The vessel will be built in China and is expected to be delivered early in 2027.
--- ---
6. In October 2024, Hedda Knutsen was delivered to Knutsen NYK from the yard in China and commenced in December 2024 on a ten-year time charter contract with Petrobras for operation in Brazil. Petrobras has the option to extend the charter by up to five further years.
--- ---
7. In March 2025, Knutsen NYK entered into a new seven-year time charter contract with Equinor for a vessel to be constructed and which will operate in Brazil, where the charterer has an option to extend the charter by up to thirteen further years. The vessel will be built in China and is expected to be delivered early in 2028.
--- ---
8. In August 2025, Knutsen NYK entered into a new seven-year charter contract with Repsol for one vessel firm with an option to charter one further vessel, both to operate in Brazil. The firm vessel has already been ordered, while the optional vessel remains subject to declaration by the charterer. The charterer has an option to extend the firm charter by up to five additional years. The vessel(s) will be built in China and the firm vessel is expected to be delivered in early 2028.
--- ---

Outlook

As at June 30, 2025: (i) the Partnership had charters with an average remaining fixed duration of 2.6 years, with the charterers of the Partnership’s vessels having options to extend their charters by an additional 4.2 years on average and (ii) the Partnership had $895 million of remaining contracted forward revenue, excluding charterers’ options and charters agreed or signed after that date. As at June 30, 2025, the eighteen vessels which comprised the Partnership’s fleet had an average age of 10.1 years. During Q2 2025, fourteen of the vessels in our fleet operated in Brazil. With the acquisition on July 2, 2025, of the Daqing Knutsen, the average age of our fleet reduced further (to 9.7 years) and the number of vessels being operated in Brazil increased to fifteen. The market for shuttle tankers in Brazil has continued to tighten, driven by a significant pipeline of new production growth over the coming years, a limited newbuild order book, and typical long-term project viability requiring a Brent oil price of only $35 per barrel.

Shuttle tanker demand in the North Sea has remained subdued for some years, driven by the impact of COVID-19-related project delays. These conditions persisted into recent quarters, awaiting anticipated new oil production starts. Most notably, the long-anticipated Johan Castberg field in the Barents Sea and the new Penguins FPSO in the North Sea entered production recently.

Looking ahead, based on supply and demand factors with significant forward visibility and committed capital from industry participants, we believe that the overall medium and long-term outlook for the shuttle tanker market remains favourable.

In the meantime, the Partnership intends to pursue long-term visibility from its charter contracts, build its liquidity, pursue accretive dropdown transactions supportive of long-term cash flow generation, and position itself to benefit from its market-leading role in an improving shuttle tanker market. The Partnership continues to believe that key components of its strategy and value proposition are accretive investment in the fleet and a long-term sustainable distribution and buy-back program.

Moving forward, our day-to-day commercial focus remains on securing further long-term charters with high-quality counterparties that provide the Partnership with stable, predictable cashflows. We are confident that strong operational performance and the successful execution of our strategy will continue to expand our strategic and financial flexibility and to support multi-faceted value creation for our unitholders in the quarters and years ahead. 7

In the near term, the Partnership believes that there are compelling opportunities to deploy a material portion of its cash flow to facilitate dropdown transactions. The Partnership believes that dropdowns will lead to an increase in the Partnership’s capital value, with growth in contractual backlog leading to increasing cash flow over time. Together with reductions in the average age of the fleet, this increased cash flow should also facilitate refinancings. Combined with strong market fundamentals, this should provide the opportunity to increase sustainable distribution levels in the future.

The Partnership’s financial information for the quarter ended June 30, 2025 included in this press release is preliminary and unaudited and is subject to change in connection with the completion of the Partnership’s quarter end close procedures and further financial review. Actual results may differ as a result of the completion of the Partnership’s quarter end closing procedures, review adjustments and other developments that may arise between now and the time such financial information for the quarter ended June 30, 2025 is finalized.

APPENDIX A—RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

EBITDA and Adjusted EBITDA

EBITDA is defined as earnings before interest, depreciation, impairments and taxes. Adjusted EBITDA is defined as earnings before interest, depreciation, impairments, taxes and other financial items (including other finance expenses, realized and unrealized gain (loss) on derivative instruments and net gain (loss) on foreign currency transactions). EBITDA is used as a supplemental financial measure by management and external users of financial statements, such as the Partnership’s lenders, to assess its financial and operating performance and compliance with the financial covenants and restrictions contained in its financing agreements. Adjusted EBITDA is used as a supplemental financial measure by management and external users of financial statements, such as investors, to assess the Partnership’s financial and operating performance. The Partnership believes that EBITDA and Adjusted EBITDA assist its management and investors by increasing the comparability of its performance from period to period and against the performance of other companies in its industry that provide EBITDA and Adjusted EBITDA information. This increased comparability is achieved by excluding the potentially disparate effects between periods or companies of interest, other financial items, taxes, impairments and depreciation, as applicable, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect net income between periods. The Partnership believes that including EBITDA and Adjusted EBITDA as financial measures benefits investors in (a) selecting between investing in the Partnership and other investment alternatives and (b) monitoring the Partnership’s ongoing financial and operational strength in assessing whether to continue to hold common units. EBITDA and Adjusted EBITDA are non-GAAP financial measures and should not be considered as alternatives to net income or any other indicator of Partnership performance calculated in accordance with GAAP.

The table below reconciles EBITDA and Adjusted EBITDA to net income, the most directly comparable GAAP measure.
