In particular, the Costco lawsuit alleges that (i) Costco lacked effective internal control over financial reporting; (ii) as a result of the foregoing, Defendants’ statements about Costco’s business, operations, and prospects, were false and misleading and/or lacked a reasonable basis. On October 4, 2018, Costco announces that “in its upcoming fiscal 2018 Annual Report on Form 10-K, it expects to report a material weakness in internal control.

The access issues relate to the extent of privileges afforded users authorized to access company systems.” Following this news, shares of Costco fell from a close of $231.68 on October 4, 2018, to a close of $218.82 the following day.
