Public Policy Holding Company, Inc.

Disclosure Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, we carried out an evaluation of the effectiveness of our disclosure controls and procedures as of March 31, 2026. This evaluation was carried out under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q are effective at a reasonable assurance level in ensuring that information required to be disclosed in our Exchange Act reports is (1) recorded, processed, summarized and reported in a timely manner and (2) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures will prevent or detect all errors and all fraud. While our disclosure controls and procedures are designed to provide reasonable assurance of their effectiveness, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

As previously disclosed, when preparing the December 31, 2024 financial statements, we identified a material weakness in our internal control over financial reporting. Specifically, we determined that certain aspects of our control environment were not operating at the level of effectiveness required, in part due to an insufficient complement of qualified technical accounting and financial reporting personnel to consistently perform control activities, in particular those involving complex and/or non-routine transactions.

Throughout the year ended December 31, 2025, management implemented remediation actions to address this material weakness, including expanding and improving review processes, improving access to technical accounting resources, and supplementing the team with additional personnel possessing relevant experience and training. Despite these remediation efforts during the year ended December 31, 2025, management identified additional control deficiencies related to the accounting for certain transactions that, while more routine in nature than those previously identified, still required an appropriate level of judgment, technical analysis and review through the current period covered by this Quarterly Report on Form 10-Q. These deficiencies indicate that the material weakness identified in the prior year has not been fully remediated as of December 31, 2025 and has not been fully remediated as of the end of March 31, 2026.

Management has implemented and continues to refine measures designed to remediate the control deficiencies contributing to the material weakness. However, these remediation measures need to be operating effectively for a sufficient period of time to be considered appropriately remediated.

Management’s Annual Report on Internal Control over Financial Reporting

This Quarterly Report on Form 10-Q does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of the company’s registered public accounting firm due to a transition period established by rules of the SEC for newly public companies.

Changes in Internal Control over Financial Reporting.

Other than the remediation measures in regard to the material weakness mentioned above, there were no changes to our internal controls over financial reporting during the three months ended March 31, 2026 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.
