Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, our co-principal executive officers andprincipal financial officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on their evaluation of our disclosure controls and procedures, our co-principal executive officers and principal financial officer concluded that our disclosure controls and procedures were effective as of September 30, 2026 to provide reasonable assurance that information required to be disclosed by the Company in the reports that we file or submit under the Exchange Act is (a) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (b) accumulated and communicated to management, including our co-principal executive officers and principal financial officer, as appropriate to allow for timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

Other than the on-going integration activities related to the Keystone acquisition which will be included in our December 31, 2026 assessment, there have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15(d)-15(f) promulgated under the Securities Exchange Act of 1934, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting during the period covered by this Quarterly Report on Form 10-Q.

Limitations on Internal Control over Financial Reporting

An internal control system over financial reporting has inherent limitations and may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.
