Quarterly Results of Operations The following sets forth selected unaudited quarterly consolidated statements of operations data for each of the eight quarters in the period ended January 31, 2021, as well as the percentage that each line item represents of our revenue for each quarter. The information for each of these quarters has been prepared on a basis consistent with our audited annual consolidated financial statements included elsewhere in this report and, in the opinion of management, includes all adjustments of a normal, recurring nature that are necessary for the fair presentation of the results of operations for these periods in accordance with generally accepted accounting principles in the United States. This data should be read in conjunction with our audited consolidated financial statements and related notes included elsewhere in this report. These historical quarterly operating results are not necessarily indicative of the results that may be expected for a full fiscal year or any future period.
