DAVA Shareholder Alert: November 30, 2026 Lead Plaintiff Deadline in Endava plc Securities Class Action - Contact SueWallSt

Important Information Regarding Section 20(a) Individual Liability Claims: The complaint names Endava's CEO and CFO as alleged control persons over filings that described internal controls as effective while accounting for certain customer and supplier agreements allegedly required additional review.

NEW YORK, Oct. 1, 2026 /PRNewswire/ -- SueWallSt notifies investors in Endava plc (NYSE: DAVA) that CEO John Cotterell and CFO Mark Thurston face alleged personal securities liability, including Section 20(a) control person claims, in a class action filed on behalf of purchasers of Endava securities between September 4, 2025 and September 21, 2026. Find out if you may be eligible to recover losses. You may also contact Joseph E. Levi, Esq. at [email protected] or (888) SueWallSt.

Endava's American Depositary Shares fell $0.68 per share, or 24.37%, on September 22, 2026, on unusually heavy trading volume after the Company placed its CFO on administrative leave. The window to apply for lead plaintiff closes on November 30, 2026.

The Named Individual Defendants

The complaint charges that Mr. Cotterell and Mr. Thurston, who served as CEO and CFO at all relevant times, had the power to control the contents of Endava's SEC reports, press releases, and presentations to analysts and portfolio managers. Each allegedly received these materials before or shortly after release and could have stopped or corrected them.

On September 21, 2026, the Board, acting on the Audit Committee's recommendation, placed Mr. Thurston on leave pending an investigation by independent outside counsel and named an interim CFO from AlixPartners. As averred, the investigation followed concerns raised by Endava's outside auditors about the accounting treatment of certain customer and supplier agreements.

Alleged Section 20(a) Control Person Liability

• Authority over disclosures: Both officers allegedly shaped the fiscal 2025 annual report on Form 20-F and each quarterly results announcement issued during the Class Period.
• Controls sign-off: The FY2025 annual report stated that management, with the participation of the CEO and CFO, concluded internal control over financial reporting was effective as of June 30, 2025.
• Undisclosed review: The pleading asserts neither officer disclosed that the customer and supplier agreement accounting required additional review, which allegedly meant Endava would delay its fourth quarter and full year 2026 results.
• Alleged knowledge: Given their positions and access to non-public information, both defendants allegedly knew adverse facts were being withheld from the market.
• Two layers of claims: Each individual is named under Section 10(b) and Rule 10b-5 as well as Section 20(a), which targets those alleged to have controlled the Company.

Sarbanes-Oxley Certification Obligations

Sections 302 and 906 of the Sarbanes-Oxley Act generally require a company's principal executive and financial officers to personally certify its annual reports, while Section 404 requires a management report on internal controls. The complaint charges that there was reason to doubt the effectiveness of Endava's controls during the Class Period, despite the effective-controls conclusion reached with both officers' participation.

"Corporate officers have a duty to ensure their companies' public statements are accurate and complete. The complaint alleges that Endava's CEO and CFO took part in an assessment finding internal controls effective, while outside auditors later raised accounting concerns that preceded the CFO's administrative leave. This litigation will test whether those officers bear personal responsibility for the alleged investor losses," said Joseph E. Levi, Esq.
