STAR GROUP, L.P.

Controls and Procedures

a) Evaluation of disclosure controls and procedures

The General Partner’s chief executive officer and chief financial officer evaluated the effectiveness of the Company’s disclosure controls and procedures (as that term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended) as of March 31, 2026. Based on that evaluation, such chief executive officer and chief financial officer concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2026, at the reasonable level of assurance. For purposes of Rule 13a-15(e), the term disclosure controls and procedures means the controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the “Act”) (15 U.S.C. 78a et seq.) is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its chief executive officer and chief financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

b) Change in internal control over financial reporting

No changes in the Company’s internal control over financial reporting occurred during the Company’s most recent fiscal quarter that has materially affected or is reasonably likely to materially affect the Company’s internal control over financial reporting.

c) Other

The General Partner and the Company believe that a controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a Company have been detected. Therefore, a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Our disclosure controls and procedures are designed to provide such reasonable assurances of achieving our desired control objectives, and the chief executive officer and chief financial officer of the General Partner have concluded, as of March 31, 2026, that our disclosure controls and procedures were effective in achieving that level of reasonable assurance.
