On July 8, 2024, after the market closed, Dril-Quip disclosed in a Form 8-K filing that it had made an error in the classification of certain inventory write-downs from 2021. Specifically, the Company stated that it had “misclassified inventory write-downs from 2021 totaling approximately $67 million” by classifying these charges as “Restructuring and other charges” when they should have been classified in “Cost of Sales.” Further, the Company said that “the Audit Committee concluded that management’s report on internal control over financial reporting as of December 31, 2023 should no longer be relied upon,” that it intends to file restated consolidated financial statements for the affected period, and that the Company “will disclose a material weakness” since it did not design and maintain effective controls over the financial statement classification of inventory write-downs related to restructurings. Following this news, the price of Dril-Quip shares fell $1.76 per share, or 9.9%, to close at $16.01 per share on July 9, 2024.
