SAN DIEGO, June 30, 2025 (GLOBE NEWSWIRE) -- Robbins LLP reminds stockholders that a class action was filed on behalf of investors who purchased or otherwise acquired DoubleVerify Holdings, Inc.

The Allegations: Robbins LLP is Investigating Allegations that DoubleVerify Holdings, Inc. (DV) Misled Investors Regarding its Business Prospects

According to the complaint, during the class period, defendants failed to disclose that: (a) DoubleVerify’s customers were shifting their ad spending from open exchanges to closed platforms, where the Company’s technological capabilities were limited and competed directly with native tools provided by platforms like Meta Platforms and Amazon; (b) DoubleVerify’s ability to monetize on its Activation Services was limited because the development of its technology for closed platforms was significantly more expensive and time-consuming than disclosed to investors; (c) DoubleVerify’s Activation Services in connection with certain closed platforms would take several years to monetize; (d) DoubleVerify’s competitors were better positioned to incorporate AI into their offerings on closed platforms, which impaired DoubleVerify’s ability to compete effectively and adversely impacted the Company’s profits; (e) DoubleVerify systematically overbilled its customers for ad impressions served to declared bots operating out of known data center server farms; and (f) DoubleVerify’s risk disclosures were materially false and misleading because they characterized adverse facts that had already materialized as mere possibilities.

The complaint alleges that the truth was revealed on February 27, 2025, when DoubleVerify reported lower-than-expected fourth quarter 2024 sales and earnings due in part to reduced customer spending and the suspension of DoubleVerify services by a large customer. Defendants also disclosed that the shift of ad dollars from open exchanges to closed platforms was negatively impacting the Company. On this news, DoubleVerify’s stock price dropped $7.83 per share, or 36%, from a closing price of $21.73 on February 27, 2025, to a closing price of $13.90 on February 28, 2025.
