PART III - NARRATIVE

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

DZS Inc. (the “Company”) is unable to file its Quarterly Report on Form 10-Q for the three months ended June 30, 2023 within the prescribed time period without unreasonable effort or expense because of the circumstances described below.

As previously reported in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on June 1, 2023 (the “June Form 8-K”), the Audit Committee of the Board of Directors of the Company, in consultation with the Company’s management, determined that the Company’s previously issued unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2023 (the “Subject Period”) should no longer be relied upon and should be restated due to an accounting error relating to the timing of revenue recognition with respect to certain customer projects for the Subject Period. As a result of this error, the Audit Committee initiated a review of the Company’s accounting for revenue recognition and the extent to which these matters affect the Company’s internal controls over financial reporting. The Audit Committee’s review is ongoing and no conclusions have been reached at this time.

As a result, the Company is unable to complete its unaudited condensed consolidated financial statements and file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2023 (the “Second Quarter 10-Q”) by the prescribed due date for such filing. The Company plans to file the Second Quarter 10-Q as soon as reasonably practicable following the completion of the Audit Committee’s review and the restatement. The Company is unable to provide an expected filing date at this time.

The description of the restatement and accounting error in the June Form 8-K and above was and is preliminary, unaudited and subject to further change in connection with the ongoing Audit Committee review and the completion of the restatement. Accordingly, there can be no assurance as to the actual effects of the restatement or that the Company will not determine to restate any financial statements for periods other than the Subject Period or with respect to any additional accounting errors. Moreover, there can be no assurance as to what period the revenue previously recognized in the Subject Period will ultimately be recognized.
