SABINE ROYALTY TRUST

Sabine Royalty Trust (the “Trust”) is an express trust formed under the laws of the State of Texas by the Sabine Corporation Royalty Trust Agreement (as amended, the “Trust Agreement”) made and entered into effective as of December 31, 1982, between Sabine Corporation, as trustor, and InterFirst Bank Dallas, N.A. (“InterFirst”), as trustee. The current trustee of the Trust is Argent Trust Company, a Tennessee chartered trust company (“Argent”). In accordance with the successor trustee provisions of the Trust Agreement, Argent, as trustee of the Trust (the “Trustee”) is subject to all terms and conditions of the Trust Agreement. The principal office of the Trust (sometimes referred to herein as the “Registrant”) is located at 3838 Oak Lawn Avenue, Suite 1720, Dallas, Texas, 75219. The telephone number of the trust is 1-855-588-7839.

The Trust maintains an Internet website, and as a result, reports such as its annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to such reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, will now be made available athttp://www.sbr-sabine.com as soon as reasonably practicable after such information is electronically filed with or furnished to the SEC.

On November 12, 1982, the shareholders of Sabine Corporation approved and authorized Sabine Corporation’s transfer of royalty and mineral interests, including landowner’s royalties, overriding royalty interests, minerals (other than executive rights, bonuses and delay rentals), production payments and any other similar, nonparticipatory interests, in certain producing and proved undeveloped oil and gas properties located in Florida, Louisiana, Mississippi, New Mexico, Oklahoma and Texas (the “Royalty Properties”) to the Trust. The conveyances of the Royalty Properties to the Trust were effective with respect to production as of 7:00 a.m. (local time) on January 1, 1983.

In order to avoid uncertainty under Louisiana law as to the legality of the Trustee’s holding record title to the Royalty Properties located in that state, title to such properties has historically been held by a separate trust formed under the laws of Louisiana, the sole beneficiary of which was the Trust. Sabine Louisiana Royalty Trust was a passive entity, with the trustee thereof, Hibernia National Bank in New Orleans, having only such powers as were necessary for the collection of and distribution of revenues from and the protection of the Royalty Properties located in Louisiana and the payment of liabilities of Sabine Louisiana Royalty Trust. Argent now serves as Trustee of the Sabine Louisiana Royalty Trust, since Louisiana law now permits anout-of-state company to act in this capacity. A separate trust also was established to hold record title to the Royalty Properties located in Florida. Legislation was adopted in Florida in 1992 that eliminated the provision of Florida law that prohibited the Trustee from holding record title to the Royalty Properties located in that state. In November 1993, record title to the Royalty Properties held by the trustee of Sabine Florida Land Trust was transferred to the Trustee. As used herein, the term “Royalty Properties” includes the Royalty Properties held directly by the Trust and the Royalty Properties located in Louisiana and Florida that were held indirectly through the Trust’s ownership of 100 percent beneficial interest of Sabine Louisiana Royalty Trust and Sabine Florida Land Trust. In discussing the Trust, this report disregards the technical ownership formalities described in this paragraph, which have no effect on the tax or accounting treatment of the Royalty Properties, since the observance thereof would significantly complicate the information presented herein without any corresponding benefit to Unit holders.

Certificates evidencing units of beneficial interest (the “Units”) in the Trust were mailed on December 31, 1982 to the shareholders of Sabine Corporation of record on December 23, 1982, on the basis of one Unit for each outstanding share of common stock of Sabine Corporation. The Units are listed and traded on the New York Stock Exchange under the symbol “SBR.”

In May 1988, Sabine Corporation was acquired by Pacific Enterprises. Through a series of mergers, Sabine was merged into Pacific Enterprises Oil Company (USA) (“Pacific (USA)”), which in turn was merged and consolidated into

Sempra Energy, effective January 1, 1993. As of August 1, 2006, Sempra sold its various interests and rights to Providence Energy Corporation (“PEC”). PEC in turn transferred its interests and rights to RJ Holdings, Inc. (“RJ Holdings”) as of June 1, 2021. These transactions had no effect on the Units. RJ Holdings, Inc. as successor to Sabine, has assumed by operation of law all of Sabine’s rights and obligations with respect to the Trust. References herein to RJ Holdings, Inc. shall be deemed to include Sabine Corporation where appropriate.

In connection with the transfer of the Royalty Properties to the Trust upon its formation, Sabine Corporation had reserved to itself all executive rights, including rights to execute leases and to receive bonuses and delay rentals. Through a series of mergers, Sabine was merged into Pacific Enterprises Oil Company (USA) (“Pacific (USA)”), a California corporation which in turn was merged and consolidated into Sempra Energy, effective January 1, 1993. In January 1993, Pacific (USA) completed the sale of substantially all of Pacific (USA)’s producing oil and gas assets to Hunt Oil Company. The sale did not include the executive rights relating to the Royalty Properties, and Pacific (USA)’s ownership of such rights was not affected by the sale. The Trustee currently reviews all leases executed on the Trust’s behalf.

On January 9, 2014, Bank of America, N.A. (as successor to InterFirst Bank Dallas, N.A.) gave notice to Unit holders that it was resigning as the Trustee subject to certain conditions including the appointment of Southwest Bank as trustee of the Trust. At a special meeting of Trust Unit holders, the Unit holders approved the appointment of Southwest Bank as successor trustee of the Trust, once Bank of America, N.A.’s resignation took effect. The effective date of Bank of America, N.A.’s resignation and the effective date of Southwest Bank’s appointment as successor trustee was May 30, 2014.

Effective October 19, 2017, Simmons First National Corporation (“SFNC”) completed its acquisition of First Texas BHC, Inc., the parent company of Southwest Bank. SFNC is the parent of Simmons Bank. SFNC merged Southwest Bank with Simmons Bank effective February 20, 2018.

On November 4, 2021, Simmons Bank, as Trustee, announced that it had entered into an agreement with Argent, pursuant to which Simmons Bank would resign as trustee of the Trust and would nominate Argent as successor trustee of the Trust. At a special meeting of Trust Unit holders, the Unit holders approved the appointment of Argent as successor trustee of the Trust. Simmons Bank’s resignation as trustee, and Argent’s appointment as successor trustee, became effective December 30, 2022.

The defined term “Trustee” as used herein shall refer to Bank of America, N.A. for periods prior to May 30, 2014, shall refer to Southwest Bank for periods from May 30, 2014 through February 19, 2018, shall refer to Simmons Bank for periods on and after February 20, 2018 through December 29, 2022, and shall refer to Argent for periods on and after December 30, 2022.

The definitions, formulas, accounting procedures and other terms governing the Trust are complex and extensive and no attempt has been made below to describe all such provisions. Capitalized terms not otherwise defined herein are used with the meanings ascribed to them in the Trust Agreement.
