Flowco Holdings Inc.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), has 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 of March 31, 2026.

Based on the evaluation of our disclosure controls and procedures, our CEO and CFO concluded that our disclosure controls and procedures were not effective as of March 31, 2026 due to the material weaknesses in our internal control over financial reporting described below.

Notwithstanding the material weaknesses discussed below, we believe our condensed consolidated financial statements fairly present, in all material respects, our financial condition, results of operations, and cash flows for the periods presented, in accordance with GAAP.

Previously Reported Material Weaknesses

As disclosed in Item 9A – Controls and Procedures, of our Annual Report, we previously identified material weaknesses in our internal control over financial reporting, which continue to exist as of March 31, 2026. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

We identified the following material weaknesses in our internal control over financial reporting:

•

We did not design and maintain an effective control environment commensurate with our financial reporting requirements. Specifically, we lacked a sufficient complement of resources with an appropriate level of accounting knowledge, experience and training to appropriately analyze, record and disclose accounting matters timely and accurately and establish effective processes and controls. Additionally, the lack of a sufficient number of professionals resulted in an inability to consistently establish appropriate authorities and responsibilities in pursuit of our financial reporting objectives, as demonstrated by, among other things, insufficient segregation of duties in the finance and accounting functions.

This material weakness contributed to the following additional material weaknesses:

•

We did not design and maintain effective controls related to the period-end financial reporting process, including designing and maintaining formal accounting policies, procedures and controls to achieve, complete, accurate and timely financial accounting, reporting and disclosures. Additionally, we did not design and maintain effective controls over the preparation and review of account reconciliations and journal entries, including maintaining appropriate segregation of duties for all significant accounts.

•

We did not design and maintain processes and controls to analyze and account for non-routine, unusual or complex transactions. Specifically, we did not design and maintain controls over the review of transactions utilizing a specialist.

•

We did not design and maintain effective IT general controls for information systems that are relevant to the preparation of our financial statements. Specifically, we did not design and maintain:

o

(i) program change management controls to ensure that program and data changes are identified, tested, authorized and implemented appropriately;

o

(ii) user access controls to ensure appropriate segregation of duties and to adequately restrict user and privileged access to appropriate personnel;

o

(iii) computer operations controls to ensure that processing and transfer of data, and data backups and recovery are monitored; and

o

(iv) program development controls to ensure that new software development is tested, authorized and implemented appropriately.

The material weaknesses resulted in a revision to a disclosure in the consolidated financial statements as of and for the year ended December 31, 2023, and immaterial adjustments to the consolidated financial statements as of and for the years ended December 31, 2023 and 2022, and as of and for the nine-month period ended September 30, 2024. The material weaknesses also resulted in adjustments recorded prior to the issuance of the consolidated financial statements as of and for the year ending December 31, 2024 and an adjustment to a disclosure recorded prior to the issuance of the condensed consolidated financial statements as of and for the nine-month period ended September 30, 2024. The material weaknesses also resulted in a revision to the previously issued consolidated financial statement for the interim periods prior to September 30, 2025, the annual period ended December 31, 2024 and the previously filed prospectus for the nine months ended September 30, 2024. These material weaknesses could result in misstatements of substantially all of our accounts or disclosures that would result in a material misstatement to the annual or interim financial statements that would not be prevented or detected.

Remediation Plans

We have taken, and will continue to take, steps to address the material weaknesses, including:

•

We have hired, and will continue to hire, additional accounting, internal audit, and information technology personnel to establish effective processes and controls, including establishing appropriate segregation of duties;

•

We have developed, and continue to refine, formal accounting policies, procedures and controls related to the period-end financial reporting process including designing and maintaining controls over account reconciliations, journal entries, and financial reporting and disclosures;

•

We have designed and maintained processes and controls to analyze and account for non-routine, unusual or complex transactions, including review of transactions utilizing a specialist; and

•

We have implemented, and plan to continue to enhance, information technology governance processes, including our program change management, computer operations, program development, and user access controls, enhancing role-based access, and more robust information technology policies and procedures.

We are committed to maintaining a strong internal control environment and implementing measures designed to help ensure that control deficiencies contributing to the material weaknesses are remediated. We have made progress towards remediation and will continue to implement our remediation plan for the material weaknesses in internal control over financial reporting described above. We will not consider the material weaknesses remediated until the applicable controls operate for a sufficient period of time, and management has concluded, through testing, that the controls are operating effectively.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act) during the period covered in this Quarterly Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.
