Endava American Depositary Shares Drop 24.37% to $2.11 Following Accounting Scrutiny and CFO Leave

Trading in Endava plc securities experienced a sharp contraction as American Depositary Shares surrendered nearly a quarter of their trading worth in a single trading session.¹ The equity units sustained a reduction of $0.68 per share during market activity concluded on September 22, 2026.¹ Expressed in proportional terms, this contraction represented a single-day loss of 24.37% of the equity value.¹ Following that day of heavy downward pressure, the American Depositary Shares established a closing level of $2.11.¹ The steep descent down to $2.11 reflected immediate shareholder reaction following revelations regarding internal company oversight and corporate accounting.¹

The primary catalyst for this downward price adjustment emerged late in the prior business cycle on September 21, 2026.¹ Following the formal conclusion of regular public trading on September 21, 2026, Endava made an official disclosure to the investing marketplace.¹ The corporate release disclosed that Chief Financial Officer Mark Thurston had been formally removed from active operational duties and placed on administrative leave.¹ This administrative separation of Mark Thurston represented a direct corporate leadership suspension occurring just before the equity price tumbled the following morning.¹

The executive suspension of Mark Thurston originated from a formal proposal issued by the Audit Committee inside Endava.¹ External auditors had previously documented specific reservations regarding the technical accounting treatment applied to particular contractual agreements.¹ In response to those accounting issues raised by auditing personnel, the Audit Committee directed that an inquiry be instituted.¹ The committee determined that Mark Thurston should remain on administrative leave while an independent outside legal counsel completes a formal inquiry into the disputed agreements.¹ This pending outside inquiry focuses squarely on the proper bookkeeping methodology applied to those underlying contracts.¹

The swift disclosure of these auditing objections immediately precipitated the market retreat recorded across Endava securities.¹ When regular markets resumed operations on September 22, 2026, market participants responded directly to the news that the finance chief was under scrutiny.¹ The decline of $0.68 per share directly erased 24.37% of the valuation held by American Depositary Shares prior to that trading day.¹ By the end of September 22, 2026, the equity rested at $2.11, setting off consequential legal steps for individuals and institutions who had acquired shares.¹

Legal rights to participate in the resulting collective judicial actions belong specifically to a defined class of securities holders.¹ Eligibility applies strictly to purchasers who obtained or accumulated Endava securities starting on September 4, 2025.¹ The qualifying calendar span closes on September 21, 2026, the specific calendar date when the corporate officer suspension was announced after market close.¹ Individuals or entities who purchased shares between September 4, 2025 and September 21, 2026 are counted among those eligible to pursue lead roles in the litigation.¹

Under established legal guidelines governing collective shareholder cases, one participant is designated by the court to guide the overall process.¹ This judicial designation names a court-appointed lead plaintiff selected from among qualifying class members.¹ The selection criteria require the court to appoint an adequate and typical representative possessing the largest financial interest in the claims.¹ Once confirmed in that specific judicial capacity, that designated individual or organization formally directs the broader court proceedings on behalf of the group.¹

Securities holders seeking to assume this leadership role must observe strict calendar boundaries established for the litigation.¹ Public notices provide an official reminder that the filing threshold is set for November 30, 2026.¹ Every eligible security purchaser retains the option to submit a formal motion to the judiciary before that calendar deadline lapses.¹ Applications petitioning the bench for appointment as the official lead plaintiff must be formally registered no later than November 30, 2026.¹

Shareholders examining their procedural choices have access to representation through specialized legal practices such as Faruqi & Faruqi LLP.¹ The legal practice of Faruqi & Faruqi LLP was originally established in the year 1995.¹ In describing its institutional record, the firm reports that it has successfully recovered hundreds of millions of dollars on behalf of aggrieved investors across the decades.¹ That cumulative recovery figure represents the firm's historical work across shareholder actions carried out since its establishment in 1995.¹

Eligible investors considering their options before the November 30, 2026 cut-off can reach out directly to obtain formal legal advice.¹ Legal counsel can be requested directly from Josh Wilson, who serves as a partner at Faruqi & Faruqi LLP.¹ Inquiries may be initiated through the toll-free telephone connection by dialing 877-247-4292.¹ Alternatively, investors may contact partner Josh Wilson via the New York telephone number 212-983-9330, using extension 1310.¹ These communication lines allow participants who held Endava securities between September 4, 2025 and September 21, 2026 to evaluate their position prior to November 30, 2026.¹
