Sezzle Inc.

Evaluation of Disclosure Controls and Procedures

As of September 30, 2026, Sezzle conducted an evaluation, under supervision and with the participation of management, including the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (Exchange Act).

Based upon that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were not effective at a reasonable assurance level, due to the material weakness described in Management’s Annual Report on Internal Control over Financial Reporting as disclosed in the Company’s 2025 Form 10-K. Disclosure controls and procedures are defined by Rules 13a-15(e) and 15d-15(e) of the Exchange Act as controls and other procedures that are designed to ensure that information required to be disclosed by us in reports filed with the SEC under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports filed under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

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 a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Management previously identified a material weakness in internal control over financial reporting as we did not design and maintain effective controls to evaluate the appropriate classification of the cash flows related to our notes receivable. This material weakness resulted in the restatement of our Consolidated Statement of Cash Flows for the year ended December 31, 2024, as well as a material misclassification of the Consolidated Statements of Cash Flows for the three months ended March 31, 2025 and 2024, six months ended June 30, 2025 and 2024, and nine months ended September 30, 2025 and 2024. If not remediated, this material weakness could result in misstatements of the aforementioned cash flow statements or related disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Remediation Plan

To remediate the material weakness in its internal control over financial reporting related to the classification of notes receivable in our Consolidated Statements of Cash Flows, we continue to execute upon the enhanced control over the classification of our notes receivable we introduced during the three months ended June 30, 2026. While the control we implemented has now operated as designed over the previous two quarters, the material weakness cannot be considered remediated until the control has operated for a sufficient period of time and management has concluded, through testing, that the control is operating effectively. We expect to conclude on the operating effectiveness of this control next quarter.

Changes in Internal Control Over Financial Reporting

As of September 30, 2026, our management, with the participation of our Principal Executive Officer and Principal Financial Officer, evaluated our internal control over financial reporting. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that no changes in our internal control over financial reporting occurred during the three months ended September 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
