Tim Santo, Adtran's SVP and CFO, commented, "While the timing is unfortunate and requires the postponement of the annual meeting of stockholders, we are fully committed to filing the restatements on or before May 19, and we do not expect the restatements to set forth material changes to the financial information presented in the preliminary earnings release." Completion and filing of the Restatements with the SEC are expected to be completed as soon as practicable, at which time the Company will notify stockholders of the new date and time of its Annual Meeting.
