PART III - NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

WEX Inc. (the “Company”) is unable, without unreasonable effort or expense, to file its annual report on Form 10-K for the year ended December 31, 2016 within the prescribed time period because it requires additional time to complete its assessment of the Company’s internal control over financial reporting; accordingly, the Company’s independent registered accounting firm, Deloitte & Touche LLP (“Deloitte”), has not yet completed its audit of the Company’s internal control over financial reporting as of December 31, 2016.  As a “large accelerated filer,” the Company is required to provide management’s report on its assessment of its internal control over financial reporting, together with Deloitte’s audit pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

In the course of completing its assessment of internal control over financial reporting as of December 31, 2016, management identified a number of deficiencies related to the design and operating effectiveness of information technology (“IT”) general controls for certain information systems that comprise part of the Company’s system of internal control over financial reporting and are relevant to the preparation of its consolidated financial statements (such information technology systems are referred to as the “affected IT systems”). These deficiencies involve user access controls and program change management controls. These controls are intended to ensure that access to financial applications and data is adequately restricted to appropriate personnel, and that changes affecting the financial applications and underlying account records are made by only authorized individuals. As a result of the deficiencies identified, there is a possibility that the effectiveness of business process controls, certain of which are dependent on the affected IT systems, or electronic data and financial reports, generated from the affected IT systems, could be adversely affected. Therefore, management has concluded that, as of December 31, 2016, there was a material weakness in internal control over financial reporting related to information technology general controls in the areas of user access and program change management for the affected IT systems. As a result, the Company undertook an extensive review and analysis of the affected IT systems, which is substantially complete. Those reviews and analyses, for which the initial focus was on the most critical systems and material account balances and classes of transactions continue, and accordingly, Deloitte's audit is not finished.

Based on the reviews and analyses to date, the Company does not expect adjustments to the previously announced financial results. The Company is working diligently to finalize the assessment of internal control over financial reporting and obtain the related attestation from Deloitte. The Company expects to finalize its financial results and file its Annual Report on Form 10-K no later than the prescribed due date allowed pursuant to Rule 12b-25.
