STAR GROUP, L.P.

(a) Evaluation of disclosure controls and procedures.

Our general partner’s chief executive officer and our 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 September 30, 2025. 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 September 30, 2025 at the reasonable level of assurance. For purposes of Rule 13a-15(e), the term disclosure controls and procedures means 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 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 our chief executive officer and chief financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b) Management’s Report on Internal Control over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) under the Securities Exchange Act of 1934, as amended. Under the supervision of management and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our evaluation of internal control over financial reporting, our management concluded that our internal control over financial reporting was effective as of September 30, 2025.

The effectiveness of our internal control over financial reporting as of September 30, 2025 has been audited by our independent registered public accounting firm, as stated in their report which is included at Item 8 – Financial Statements and Supplementary Data.

(c) Change in Internal Control over Financial Reporting.

There were no changes in our internal control over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(d) Other.

Our 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, or will be met, and that regardless of our evaluation of controls we cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Therefore, our controls system, no matter how well we believe it may be conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the Company's controls system are met, or will be 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 our general partner have concluded, as of September 30, 2025, that our disclosure controls and procedures were effective in achieving that level of reasonable assurance.
