SAN JUAN BASIN ROYALTY TRUST

The Trust maintains a system of internal disclosure controls and procedures that is designed to ensure that the information required to be disclosed in the Trust’s filings under the Exchange Act is recorded, processed, summarized, and reported within the times specified in the SEC’s rules and forms. In its evaluation of its disclosure controls and procedures, the Trustee has relied, to the extent considered reasonable, on information provided by Hilcorp, the owner of the properties. Consequently, the Trust’s ability to timely and accurately disclose relevant information in its periodic reports is dependent upon Hilcorp’s timely delivery of accurate oil and gas revenue and production cost information and, therefore, the Royalty Income owed to the Trust.

The Conveyance that transferred the royalty to the Trust obligates Hilcorp to provide the Trust with certain financial and operational information, including information concerning calculations of Royalty Income owed to the Trust. Once the Trust receives the financial information from Hilcorp, the Trust engages independent public accountants, compliance auditors, attorneys, and petroleum engineers in order to assist the Trustee in evaluating the accuracy and completeness of the information required to be disclosed in the Trust’s periodic reports. These outside professionals advise the Trustee in its review and compilation of this information for inclusion in this Quarterly Report on Form 10-Q and the other periodic reports provided by the Trust to the SEC.

The Trustee continues to engage with Hilcorp regarding its ongoing accounting and reporting to the Trust, and the Trust’s third-party compliance auditors continue to audit payments made by Hilcorp to the Trust, inclusive of sales revenues, production costs, capital expenditures, adjustments, actualizations, and recoupments. The Trust’s auditing process has also included detailed analysis of Hilcorp’s pricing and rates charged. As previously disclosed in the Trust’s filings, these revenues and costs (along with all costs) are the subject of the Trust’s ongoing comprehensive audit process by our professional consultants and outside counsel to help evaluate compliance with the underlying operative Trust agreements and evaluate potential remedies in the event there is suspected non-compliance.

The Trustee has evaluated the Trust’s internal disclosure controls and procedures as of September 30, 2025, and has concluded that such disclosure controls and procedures are effective, at the “reasonable assurance” level (as such term is used in Rule 13a-15(f) of the Exchange Act), to ensure that material information received from Hilcorp is gathered on a timely basis to be included in the Trust’s periodic reports and recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Additionally, during the three months ended September 30, 2025, there were no changes in the Trust’s internal control over financial reporting (as such term is used in Rule 13a-15(f) of the Exchange Act) that materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting. Because the Trust does not have, nor does the Indenture provide for, officers, a board of directors or an independent audit committee, the Trustee has reviewed neither the Trust’s disclosure controls and procedures nor the Trust’s internal control over financial reporting in concert with management, a board of directors or an independent audit committee.
