EARNINGS RELEASE—INTERIM RESULTS FOR THE PERIOD ENDED DECEMBER 31, 2023

Financial Highlights

For the three months ended December 31, 2023 (“Q4 2023”), KNOT Offshore Partners LP (“KNOT Offshore Partners” or the “Partnership”):

Other Partnership Highlights and Events

Derek Lowe, Chief Executive Officer and Chief Financial Officer of KNOT Offshore Partners LP, stated, “We are pleased to report another strong performance in Q4 2023, marked by safe operation at over 99% fleet utilization for scheduled operations, along with consistent revenue and operating income.

1 EBITDA and Adjusted EBITDA are non-GAAP financial measures used by management and external users of the Partnership’s financial statements. Please see Appendix A for definitions of EBITDA and Adjusted EBITDA and a reconciliation to net income, the most directly comparable GAAP financial measure.

Including those contracts signed since December 31, 2023, we now have 79% of charter coverage in 2024 from fixed contracts, which rises to 91% if charterers’ options are exercised. Having executed a number of new contracts, we remain focused on filling the remaining gaps in our charter portfolio.

In Brazil, the main offshore oil market where we operate, the outlook is continuing to improve, with robust demand and increasing charter rates. Driven by Petrobras’ continued high production levels and FPSO start-ups in the pre-salt fields that rely upon shuttle tankers, we believe the world’s biggest shuttle tanker market is tightening materially. Our secondary geography, in the North Sea, is taking longer to re-balance, where we anticipate progressive improvement during and beyond 2024.

We are aware that Knutsen NYK has recently ordered three new shuttle tankers with delivery over 2026-2027; and we note recent reports of another operator ordering three new shuttle tankers, with delivery by early 2027. 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-long term demand for the global shuttle tanker fleet. These new orders bring anticipated deliveries to a total of eleven within the coming three years. While delivery of these orders will add to the supply of vessels into the global shuttle tanker fleet, 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 in the coming years, particularly as increasing numbers of shuttle tankers reach or exceed typical retirement age.

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 cashflows from long-term employment with high quality counterparties, and are confident that continued operational performance and execution of our strategy can create unitholder value in the quarters and years ahead.”

Financial Results Overview

Results for Q4 2023 (compared to those for the three months ended September 30, 2023 (“Q3 2023”)) included:

By comparison with the three months ended December 31, 2022 (“Q4 2022”), results for Q4 2023 included:

Fleet utilization

The Partnership’s vessels operated throughout Q4 2023 with 99.6% utilization for scheduled operations, and 96.0% utilization taking into account the scheduled drydockings of the Torill Knutsen and the Ingrid Knutsen, which were offhire for 23 days and 33 days respectively in Q4 2023.

Financing and Liquidity

As of December 31, 2023, the Partnership had $63.9 million in available liquidity, which was comprised of cash and cash equivalents of $63.9 million. The Partnership’s revolving credit facilities are fully drawn and mature between August 2025 and November 2025.

The Partnership’s total interest-bearing obligations outstanding as of December 31, 2023 were $963.0 million ($956.8 million net of debt issuance costs). The average margin paid on the Partnership’s outstanding debt during Q4 2023 was approximately 2.28% over SOFR. These obligations are repayable as follows:

As of December 31, 2023, the Partnership had entered into various interest rate swap agreements for a total notional amount outstanding of $426.5 million, to hedge against the interest rate risks of its variable rate borrowings. As of December 31, 2023, the Partnership receives interest based on SOFR and pays a weighted average interest rate of 1.9% under its interest rate swap agreements, which have an average maturity of approximately 1.8 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 December 31, 2023, the Partnership’s net exposure to floating interest rate fluctuations was approximately $294.5 million based on total interest-bearing contractual obligations of $963.0 million, less the Raquel Knutsen and Torill Knutsen sale and leaseback facilities of $178.1 million, less interest rate swaps of $426.5 million, and less cash and cash equivalents of $63.9 million.

On January 9, 2024, the loan facility secured by the Dan Sabia was repaid in full with a $10.4 million payment. The Dan Sabia and the Dan Cisne are now debt-free and there are no plans to incur additional borrowings secured by these vessels until such time as the Partnership has better visibility on the vessels’ future employment.

In May 2024, the loan facility secured by the Hilda Knutsen is due for repayment, for which the balloon repayment is $57 million. Negotiations are well-advanced with potential lenders for a new facility, to be secured also by the Hilda Knutsen, sufficient to finance the balloon repayment of the maturing facility. Management believe that such facility will be refinanced on acceptable and similar terms prior to maturity. However, there can be no guarantees of the success of any financing exercise.

On November 2, 2023, the Partnership entered into an at-the-market sales agreement with B. Riley Securities, Inc. for a new ATM program pursuant to which the Partnership may offer and sell up to $100 million of common units from time to time, through the Agent. This new sales agreement replaces and supersedes the prior sales agreement with the Agent entered into on August 26, 2021, which had provided for a $100 million at-the-market offering program for our common units. The Partnership intends to use the net proceeds of any sales of offered units for general partnership purposes, which may include, among other things, the repayment of indebtedness or the funding of acquisitions or other capital expenditures.

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.

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.

Knutsen NYK owns, or has ordered, the following vessels and has entered into the following charters:

Outlook

At December 31, 2023, the Partnership’s fleet of eighteen vessels had an average age of 9.7 years, and the Partnership had charters with an average remaining fixed duration of 2.0 years, with the charterers of the Partnership’s vessels having options to extend their charters by an additional 2.1 years on average. The Partnership had $699 million of remaining contracted forward revenue at December 31, 2023, excluding charterers’ options and excluding contracts agreed or signed after that date.

The market for shuttle tankers in Brazil, where fourteen of our vessels have been operating, has continued to tighten in Q4 2023, 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. While the Dan Cisne and Dan Sabia stand out among the Partnership’s fleet as being of a smaller size than is optimal in today’s Brazilian market, we remain in discussions with our customers and continue to evaluate all our options for the Dan Cisne and Dan Sabia vessels, including but not limited to redeployment in the tightening Brazilian market, deployment to the North Sea, charter to Knutsen NYK (subject to negotiation and approvals) and sale.

Shuttle tanker demand in the North Sea has remained subdued, driven by the impact of COVID-19-related project delays. We expect these conditions to persist for several more quarters until new oil production projects that are anticipated come on stream.

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, and position itself to benefit from its market-leading position in an improving shuttle tanker market.

The Partnership’s financial information for the year ended December 31, 2023 included in this press release is preliminary and unaudited and is subject to change in connection with the completion of the Partnership’s year end close procedure and further financial review, Actual results may differ as a result of the completion of the Partnership’s year end closing procedures, review adjustment and other developments that may arise between now and the time the audit for the year ended December 31, 2023 is finalized.

APPENDIX A—RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

EBITDA and Adjusted EBITDA

EBITDA is defined as earnings before interest, depreciation 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.
