Amendment Description	Explanatory Note This Amendment No. 1 to Form 10-Q (this Amendment) amends the Quarterly Report on Form 10-Q for the three and nine months ended October 31, 2015 originally filed with the Securities and Exchange Commission (SEC) on December 4, 2015 (the Original Filing) by Raven Industries, Inc. (the Company). Restatement As further discussed in Note 2 to our unaudited consolidated financial statements in Part I, Item 1. "Financial Statements" of this Quarterly Report on Form 10-Q/A, subsequent to the issuance of the Original Filing, we and our Audit Committee concluded that we should restate our previously issued consolidated financial statements to correct for errors related to (i) the impairment of goodwill, finite-lived intangibles, and other long-lived assets related to our Vista reporting unit; (ii) the fair value of acquisition-related contingent consideration; and (iii) income tax accounting. In connection with the restatement, the Company also recorded adjustments for certain other errors which management has concluded are immaterial. These corrections will also result in a restatement of our consolidated financial statements for the year ended January 31, 2016 and of our unaudited consolidated financial statements for the quarter ended April 30, 2016. We will file an amended Form 10-K and amended Form 10-Q to address these corrections. Disclosure Controls and Procedures Management has reassessed its evaluation of the effectiveness of the design and operation of its disclosure controls and procedures as of October 31, 2015. As a result of that reassessment, management has concluded that the Company did not maintain effective disclosure controls and procedures due to the material weaknesses in internal control over financial reporting which existed at that date. For a description of the material weaknesses in internal control over financial reporting and actions taken, and to be taken, to address the material weaknesses, see Part 1, Item 4. "Controls and Procedures" of this Amended Quarterly Report on form 10-Q/A. Amendment Accordingly, the purpose of this Amendment is to (i) restate our previously issued unaudited consolidated financial statements and related disclosures in Part I, Item 1. "Financial Statements" for the three and nine months ended October 31, 2015 as well as related disclosures in Part I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations," to reflect the correction of the errors described above and which were described in the Company’s Form 8-K filed with the SEC on November 23, 2016, and (ii) to amend and restate in its entirety Part I, Item 4. "Controls and Procedures" of the Original Filing to reflect the conclusions by the Company’s management that internal control over financial reporting and disclosure controls and procedures were not effective as of October 31, 2015 due to the identification of the material weaknesses which resulted in the errors described above and which were described in the Company’s Form 8-K filed with the SEC on November 23, 2016. Except as expressly set forth herein, this Amendment does not reflect events occurring after the date of the Original Filing or modify or update any of the other disclosures contained therein in any way other than as required to reflect the amendment discussed above and to enhance disclosures in Part I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations," to be consistent with the enhanced disclosures included in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2016. Accordingly, this Amendment should be read in conjunction with the Original Filing and our other filings with the SEC. The Company will also file an amendment to the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2016, originally filed with the SEC on March 29, 2016, to restate the Company's previously issued audited consolidated financial statements for the fiscal year ended January 31, 2016 to correct the errors referenced above. The Company will restate management's report on internal control over financial reporting and its evaluation of disclosure controls and procedures (to be included in its amended Annual Report on Form 10-K/A for the fiscal year ended January 31, 2016) and will receive an adverse opinion on internal control over financial reporting as of January 31, 2016 from its independent registered public accounting firm, PricewaterhouseCoopers LLP. With respect to its Form 10-Q for the quarterly period ended April 30, 2016, the Company will also restate its previously issued unaudited consolidated financial statements as well as Part I, Item 4. "Controls and Procedures."
