One-eighth of the initial 673,080 Class B Units issued by the Partnership convert to common units representing limited partner interests in the Partnership ("Common Units") on a one-for-one basis for each quarter (starting with the quarter ending September 30, 2021) that the Partnership pays distributions on the Common Units that are at or above $0.52 per quarter until no further Class B Units exist. Included in the amount beneficially owned are 245,895 Common Units, which represent the Common Units into which the 208,333 Series A Preferred Units beneficially owned were convertible at September 30, 2025.

** Calculation of percentage based on a total of 34,064,602 Common Units outstanding as of November 6, 2025. In calculating the percentage beneficially owned, 245,895 Common Units were included in both the numerator and denominator, which represent the Common Units into which the 208,333 Series A Preferred Units beneficially owned were convertible at September 30, 2025.

Explanatory Note

The Reporting Persons named in Item 2 below are hereby jointly filing this amendment (the "Amendment") to the Schedule 13D filed with the U.S Securities and Exchange Commission (the "Commission") on August 22, 2016, as amended by Amendment No. 1 filed on March 31, 2017, Amendment No. 2 filed on November 20, 2018, Amendment No. 3 filed on September 24, 2021 and Amendment No. 4 filed on November 3, 2025 (as amended, the "Schedule 13D"), to report that, on March 19, 2026, discussions between Knutsen NYK Offshore Tankers AS, a Norway limited company ("KNOT"), and the Conflicts Committee of the Board of Directors of KNOT Offshore Partners LP, a Marshall Islands limited partnership (the "Partnership" or the "Issuer"), regarding the Proposal (as defined in Item 4) were terminated.

In accordance with Rule 13d-1(k)(1)(iii) promulgated pursuant to the Exchange Act, the Reporting Persons named in Item 2 below have executed a written agreement relating to the joint filing of this Amendment (the "Joint Filing Agreement"), a copy of which is annexed hereto as Exhibit E.

**Item 4. Purpose of Transaction**

The information contained in Item 3 above is incorporated herein by reference.

KNOT acquired its Common Units (including any Common Units issuable upon conversion of the Class B Units and Series A Preferred Units) for investment purposes and (in the case of the original acquisition of the Subordinated Units) in order to effect the IPO. Each of the Reporting Persons at any time and from time to time may acquire additional Common Units or dispose of any or all of Common Units that it owns depending upon an ongoing evaluation of the investment in the Common Units, prevailing market conditions, other investment opportunities, other investment considerations and/or other factors.

Under the Limited Liability Company Agreement of the General Partner, dated February 20, 2013 (the "General Partner LLC Agreement"), KNOT has the right to designate the individuals that serve on the board of directors of the General Partner. The General Partner, in turn, has the right to appoint three of the seven directors of the Partnership. Through KNOT's right to appoint the board of directors of the General Partner and the General Partner's right to appoint three members of the board of directors of the Partnership (the "Board"), KNOT and, indirectly, the other Reporting Persons, have the ability to influence the management, policies and control of the Partnership with the aim of increasing the value of the Partnership, and thus of the Reporting Persons' investment.

Proposal

The information contained in the Explanatory Note above is incorporated herein by reference.

As previously reported, on October 31, 2025, KNOT submitted a non-binding offer letter (the "Proposal") to the Board to acquire all of the issued and outstanding Common Units that are not already beneficially owned by KNOT in exchange for cash. The Conflicts Committee of the Board and its independent advisors reviewed the Proposal and had several discussions with KNOT over the previous months regarding the Proposal. Following such discussions, the parties have determined that they will not be able to reach an agreement as to the transaction contemplated by the Proposal and have therefore terminated discussions regarding the Proposal.

The Reporting Persons continuously evaluate their investment in the Issuer and its subsidiaries and, depending on various factors including, but not limited to, the price of the Common Units, the terms and conditions of available transactions, prevailing market conditions and such other considerations as the Reporting Persons deem relevant may, at any time or from time to time, and subject to any required regulatory approvals, acquire or dispose of additional Common Units and/or other equity, debt, notes, instruments or other securities of the Issuer and/or its subsidiaries on the open market, in privately negotiated transactions, directly from or to the Issuer, upon the exercise or conversion of securities convertible into or exercisable or exchangeable for other securities or otherwise. Any such acquisition, disposition or other transaction could be effectuated through open market purchases, tender or exchange offers, exercise of the limited call right contained in the Partnership Agreement, negotiated merger transactions, privately negotiated transactions, sale transactions or otherwise.

The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.

The information contained in Items 2 and 3 above is incorporated herein by reference.

Partnership Agreement

In connection with the IDR Exchange, the Partnership amended the Previous Partnership Agreement and entered into a Fourth Amended and Restated Agreement of Limited Partnership, effective as of September 10, 2021 (the "Partnership Agreement"), which is filed as Exhibit 3.2 to the Partnership's Registration Statement on Form 8-A/A filed with the Commission on September 10, 2021.

General Partner's Right to Appoint Directors

The Partnership's board of directors consists of seven members, three of which are appointed by the General Partner ("Appointed Directors") and four of which are elected by holders of the Common Units and Class B Units ("Elected Directors"). Appointed Directors serve as directors for terms determined by General Partner. Elected Directors are divided into four classes serving staggered four-year terms. Whenever distributions payable on the Series A Preferred Units have not been declared and paid for four consecutive quarters, holders of Series A Preferred Units, together with the holders of any other series of preferred units upon which like rights have been conferred and are exercisable, will have the right to replace one of the Appointed Directors with a person nominated by such holders, such nominee to serve until all accrued and unpaid distributions on the preferred units have been paid.

Voting Restrictions

The Partnership Agreement provides that holders of the Common Units and Class B Units who are residents of Norway (including KNOT) are not eligible to vote in the election of Elected Directors. Further, if any person or group owns beneficially more than 4.9% of any class of units then outstanding, any such units owned by that person or group in excess of 4.9% may not be voted on any matter and are not considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes (except for purposes of nominating a person for election to the board of directors), determining the presence of a quorum or for other similar purposes, unless required by law. The General Partner, its affiliates (including KNOT) and persons who acquire Common Units and Class B Units with the prior approval of the board of directors are not subject to the 4.9% limitation except with respect to voting their Common Units and Class B Units in the election of the Elected Directors.

Registration Rights

Under the Partnership Agreement, the Partnership agreed to register for resale under the Securities Act of 1933, as amended, and applicable state securities laws any Common Units or other partnership interests proposed to be sold by the General Partner or any of its affiliates (including KNOT) or their assignees if an exemption from the registration requirements is not otherwise available or advisable. These registration rights continue for two years following any withdrawal or removal of the General Partner as the general partner of the Partnership. The Partnership is obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions.

Limited Call Right

Under the Partnership Agreement, if, at any time, the General Partner and its affiliates own more than 80% of the Common Units then outstanding, the General Partner has the right, but not the obligation, to purchase all, but not less than all, of the remaining Common Units at a price equal to the greater of (1) the average of the daily closing prices of the Common Units over the consecutive 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (2) the highest price paid by the General Partner or any of its affiliates for Common Units during the 90-day period preceding the date such notice is first mailed.

General Partner LLC Agreement

Under the General Partner LLC Agreement, KNOT has the right to designate the individuals that serve on the board of directors of the General Partner.

To the best knowledge of the Reporting Persons, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 with respect to any securities of the Partnership.
