The company said it expects to file the Form 10-K as soon as possible, but no later than the end of the fifteenth calendar day extension period provided under Rule 12b-25.
Vaccinex said it has filed all other periodic reports required during the preceding 12 months. It also said it does not expect a significant change in results of operations from the corresponding period of the last fiscal year to be reflected in the report.
