Introduction to the DoubleVerify Class Action Lawsuit
Our team monitored the DoubleVerify lawsuit through three devastating financial announcements. The company’s stock dropped 21.3% ($8.35 per share) at the time of February 28, 2024, after they reduced revenue growth expectations. The shares took another hit on May 7, 2024, falling 38.6% ($11.79 per share) when DoubleVerify lowered its full-year revenue outlook. The situation worsened on February 27, 2025, as disappointing Q4 earnings caused an additional 36% decline, which pushed the share price down to $13.90.
The case raises serious concerns, especially when you have allegations about DoubleVerify’s systematic overbilling of customers for ad impressions served to declared bots from known data center server farms. A damaging Adalytics Research report claimed the company’s advertisement verification services were nowhere near effective. These serious allegations have prompted a deadline of July 21, 2025, for investors to submit their lead plaintiff motions to the court.
DoubleVerify Faces Investor Lawsuit Over Stock Decline
DoubleVerify faces a major legal challenge as the Electrical Workers Pension Fund, Local 103, I.B.E.W. filed a federal class action lawsuit against the company on May 22, 2025. The digital advertising verification company has seen its stock price drop dramatically in the last year, and this lawsuit marks another significant development.
Class action filed in Southern District of New York
The United States District Court for the Southern District of New York received the DoubleVerify class action lawsuit under case number 25-cv-04332. The legal action names the corporation and two former senior executives, Mark Zagorski and Nicola Allais. This lawsuit represents all parties that bought or acquired DoubleVerify common stock between November 10, 2023, and February 27, 2025.
Affected shareholders have until July 21, 2025, to seek appointment as lead plaintiff in the lawsuit. This deadline is vital for shareholders who want to take an active role in the litigation.

Investors allege securities fraud and misleading statements
The lawsuit’s foundation rests on claims that DoubleVerify and its executives made false and misleading statements during the class period. The plaintiffs say the company failed to disclose vital information that ended up causing substantial financial losses.
Investors claim DoubleVerify hid that customers were moving their advertising spending from open exchanges to closed platforms like Meta and Amazon. The company’s technology had limited capabilities on these closed platforms and competed directly with the platforms’ native tools.
The lawsuit also claims DoubleVerify misled investors about:
- The actual costs and timeline to develop technology for closed platforms, which was “significantly more expensive and time-consuming than disclosed to investors”
- The fact that Activation Services on certain closed platforms would “take several years to monetize”
- The company’s competitive disadvantage in incorporating AI into offerings on closed platforms
- Systematic overbilling of customers “for ad impressions served to declared bots operating out of known data center server farms”
The complaint states that DoubleVerify’s risk disclosures were false and misleading because they presented existing problems as potential future risks. These allegations suggest the company’s positive statements about its business, operations, and prospects had no reasonable basis.
U.S. Senator Mark Warner’s involvement strengthened the lawsuit when he contacted the Federal Trade Commission and Department of Justice about systematic customer overcharging claims. A report from Adalytics Research on March 28, 2025, added weight by claiming DoubleVerify’s web advertisement verification and fraud protection services did not work effectively.
The company’s stock experienced three major drops during the class period, wiping out more than 80% of its market value. These dramatic declines followed disappointing financial announcements and revelations about DoubleVerify’s struggles to adapt as the industry moved toward closed advertising platforms.

What Triggered the DoubleVerify Lawsuit?
The DoubleVerify Class Action Lawsuit resulted from several devastating announcements that shook investor confidence in 2024 and early 2025. Stock prices dropped after four key disclosures, which led to legal action against this digital advertising verification company.
February 2024: Revenue growth expectations lowered
The company faced its first major setback on February 28, 2024. DoubleVerify announced lower revenue growth expectations for 2024’s first quarter. The company’s management blamed “a slow start by brand advertisers and a slow ramp by recently signed new large customers” as the main reasons behind this reduction. Investors reacted strongly to this unexpected news. The stock fell $8.35 per share (21.3%) and closed at $30.89.
This announcement served as the first red flag that showed DoubleVerify’s growth wasn’t going as planned. Investors started to wonder if these were just temporary problems or signs of deeper issues in the company’s business model.
May 2024: Full-year revenue outlook cut
Things got worse on May 7, 2024. DoubleVerify dealt another blow to investors by reducing its full-year 2024 revenue outlook. The company reduced its projections from earlier estimates because customers were “pulling back on their ad spending”. The market responded harshly. The company’s shares dropped even more, falling $11.79 per share (38.6%) to close at $18.78 on May 8, 2024.
The company adjusted its full-year revenue outlook to between $663 million and $675 million, which fell well below what the market expected. This second disappointing announcement made people more worried about the company’s health.
February 2025: Q4 earnings miss and platform shift disclosure
The lawsuit’s third major trigger came on February 27, 2025, with DoubleVerify’s fourth quarter 2024 results. The company reported revenue of $190.6 million, showing just 11% growth year-over-year, which missed expectations by a lot. The company achieved a 39% adjusted EBITDA margin, but investors weren’t impressed with the overall performance.
The biggest blow came when DoubleVerify revealed that “the shift of ad dollars from open exchanges to closed platforms was negatively affecting the Company”. This news hit hard because it showed a basic problem with DoubleVerify’s core business model. CEO Mark Zagorski admitted that “one of our largest customers facing billions of dollars of sharply escalating commodity costs, dramatically reduced its spend with DV as part of a sweeping cost reduction initiative”.
The stock price then crashed by about 36% and closed at $13.90 per share on February 28, 2025. This revelation became a key part of the lawsuit, as plaintiffs claimed the company knew about this change earlier but didn’t tell investors.
March 2025: Adalytics report exposes bot traffic issues
The final hit came on March 28, 2025. Market research company Adalytics Research published a damaging 240-page report that claimed DoubleVerify’s web advertisement verification and fraud protection services didn’t work well. The report stated that “DoubleVerify customers are regularly billed for ad impressions served to declared bots operating out of known data center server farms”.
The Wall Street Journal also reported that DoubleVerify “regularly misses detection of nonhuman traffic in contradiction to the Company’s claims that it helps brands avoid serving ads to nonhuman bot accounts”. Adalytics looked at “over a petabyte of web traffic data across more than two million websites over seven years” and found that “at least 40% of web traffic consists of fake users or computerized bots”.
DoubleVerify fought back against these claims. They called the report “inaccurate and misleading” and said Adalytics “manipulates data and uses these reports as marketing tools to sell its own services”. The damage to investor confidence was already done, which led to the class action lawsuit.
How Did the Market React to the Disclosures?
DoubleVerify’s market disclosures triggered immediate and harsh reactions from investors who responded aggressively throughout the class period.
Stock drops over 80% across three major announcements
The financial markets hammered DoubleVerify’s shares after each disclosure. The stock took a 21.3% dive ($8.35 per share) following their February 2024 announcement about lower revenue growth expectations. Things got worse in May 2024 when the revised guidance caused shares to nosedive by 38.6% ($11.79 per share), closing at $18.78.
The worst was yet to come. The February 2025 earnings report sent the stock crashing down 36% in a single day. Shares plunged from $21.73 to $13.90, hitting their lowest point ever.
These three announcements wiped out more than 80% of the company’s market value within a year. The February 2025 crash ranked among the stock’s steepest single-day falls since early May 2024. The stock had actually gained 13% year-to-date before these negative announcements.

Investor confidence shaken by repeated revenue misses
The company’s declining performance metrics steadily eroded investor confidence. Revenue growth showed a clear downward spiral – from 36% in both 2021 and 2022, dropping to 27% in 2023, then falling to 15% in 2024, with 2025 projections at just 10%.
Wall Street analysts reacted quickly. Goldman Sachs downgraded their rating and cut their price target from $24.00 to $20.00. Truist Securities pointed out that revenue suffered because “more ad spend going towards private marketplace and programmatic guaranteed on proprietary platforms at the expense of the open web”.
The situation worsened as six major customers reduced their spending in 2024. Another big customer cut back so drastically in Q4 that management excluded them completely from 2025 guidance.
Negative investor sentiment persisted beyond the class period. The stock dropped another 3.89% in after-hours trading following Q1 2025 results, despite beating revenue expectations. This reflected ongoing doubts about the company’s business model and long-term profitability.
What Are the Key Allegations in the DoubleVerify Class Action Lawsuit?
The DoubleVerify Class Action Lawsuit against DoubleVerify focuses on several serious claims of securities fraud. The legal complaint states that company executives misled their shareholders about key parts of their business model and operations.
Failure to disclose shift to closed platforms
The DoubleVerify Class Action Lawsuit claims DoubleVerify kept quiet about how customers were moving their advertising budgets from open exchanges to closed platforms like Meta and Amazon. This created problems because the company’s tech capabilities were limited on these closed platforms. The company also had to compete with tools that these platforms already offered. Their competitors were in a better position to use AI in their closed platform products, which made it harder for DoubleVerify to compete and hurt their profits.
Overbilling for bot traffic and ineffective fraud detection
The most serious claim in the DoubleVerify Lawsuit states DoubleVerify “systematically overbilled its customers for ad impressions served to declared bots operating out of known data center server farms”. This claim became more credible after Adalytics Research released a report showing the company’s web ad verification and fraud protection services didn’t work well. The Wall Street Journal later reported that DoubleVerify “regularly missed detection of nonhuman traffic” even though they claimed to help brands avoid showing ads to bots. The company strongly denied these claims and called the Adalytics report “inaccurate and misleading”. They also said the research firm “manipulates data and uses these reports as marketing tools”.
Misleading risk disclosures and monetization timelines
The DoubleVerify Lawsuit also claims DoubleVerify gave “materially false and misleading” risk disclosures by presenting existing problems as potential future risks. Investors say the company wasn’t honest about its ability to make money from Activation Services. They hid the fact that developing technology for closed platforms cost more money and took longer than what they told investors. The DoubleVerify Class Action Lawsuit points out that DoubleVerify’s Activation Services on some closed platforms would “take several years to monetize”, which was much longer than what investors expected.
What Can Investors in the DoubleVerify Lawsuit Do Now?
Legal options through the ongoing class action lawsuit remain open to investors affected by DoubleVerify’s alleged securities violations. Shareholders who bought company stock during the specified period can take action to protect their interests.
Deadline to file as lead plaintiff: July 21, 2025
The court requires potential lead plaintiffs in the DoubleVerify class action lawsuit to file their motions no later than July 21, 2025. This deadline applies to all potential lead plaintiffs whatever law firm represents them. Missing this crucial date could leave investors nowhere near the same influence over the litigation’s direction.
Criteria for lead plaintiff under PSLRA in the DoubleVerify Class Action Lawsuit
The court usually picks the investor or group with the greatest financial stake as lead plaintiff under the Private Securities Litigation Reform Act (PSLRA), provided they meet certain legal requirements. A lead plaintiff must:
- Buy DoubleVerify common stock during the Class Period (November 10, 2023 to February 27, 2025)
- Submit certification that they reviewed and authorized the complaint filing
- Show they can protect class interests fairly and properly
- Confirm they didn’t buy securities because their counsel told them to
- Share all relevant security transactions during the class period
These PSLRA rules aim to get institutional investors to step up as lead plaintiffs while keeping out “professional plaintiffs” with minimal shares.

How to join the DoubleVerify class action lawsuit
The law automatically includes investors who bought DoubleVerify stock during the class period and suffered a loss as class members. These shareholders can:
- Apply to become lead plaintiff by the July deadline
- Get personal counsel to represent individual interests
- Stay an “absent class member” without taking immediate action[222]
Investors don’t need to serve as lead plaintiff to share in any potential recovery from the lawsuit. Any settlement or judgment will benefit all class members equally.
Conclusion: Looking Ahead: The Future of DoubleVerify and Digital Ad Verification
The DoubleVerify class action lawsuit marks a defining moment that will change the digital advertising verification industry forever. Three consecutive disappointing financial announcements destroyed over 80% of the company’s market value between 2024 and 2025.
Of course, allegations against DoubleVerify tell a concerning story. The company allegedly hid vital information about customer migration to closed platforms and overbilled systematically for ad impressions served to known bots. Plaintiffs also claim DoubleVerify misled investors about knowing how to monetize Activation Services and provided deceptive risk disclosures.
Investors affected by this situation have several options available. The deadline to file as lead plaintiff comes up on July 21, 2025. Shareholders must choose between taking an active role in the litigation or staying as absent class members who would still benefit from any potential recovery.
This case reaches far beyond a single company. These events raise essential questions about transparency in ad verification technologies and adapting to faster changing digital advertising ecosystems. The situation also shows how crucial accurate disclosures become to investors, especially when core business models face serious threats.
This case will trigger more intense examination of verification claims across the digital advertising industry. Coming months will reveal if DoubleVerify can restore investor confidence or face devastating financial penalties. We will track all developments in this groundbreaking securities fraud action that has shaken the digital advertising verification world until its resolution.
