Endava puts CFO on leave, names interim finance chief

Endava plc (DAVA) announced a leadership change in its finance function and a related reporting delay.

Rhea-AI Filing Summary

Endava plc (DAVA) announced a leadership change in its finance function and a related reporting delay. The Board appointed Conor McShane of AlixPartners LLP as Interim Chief Financial Officer, and designated him as principal financial officer and principal accounting officer, effective September 21, 2026. This follows the Board’s decision, based on a recommendation from the Audit Committee, to place current CFO Mark Thurston on administrative leave, effective the same date.

Mr. Thurston’s leave is pending the conclusion of an ongoing investigation led by independent outside counsel for the Audit Committee regarding the company’s accounting treatment of certain customer and supplier agreements and related matters. Endava also disclosed that its fiscal fourth quarter and full year 2026 earnings release, conference call and Annual Report on Form 20-F for the year ended June 30, 2026 will occur on a later-than-usual timetable, with the company intending to report and file by November 2, 2026, consistent with applicable SEC deadlines.

5 terms

administrative leave regulatory

"to place Mark Thurston, the Company’s Chief Financial Officer, on administrative leave"

independent outside counsel regulatory

"an ongoing investigation being conducted by independent outside counsel for the Committee"

Annual Report on Form 20-F regulatory

"file its Annual Report on Form 20-F for the year ended June 30, 2026"

An annual report on Form 20-F is a standardized filing that foreign companies submit to the U.S. securities regulator to disclose their financial results, business operations, risks, and management’s discussion of performance. It matters to investors because it provides a complete, audited snapshot—like a company’s financial report card and shareholder letter combined—used to assess transparency, compare companies, and judge whether the stock’s price matches underlying business strengths and risks.

registration statement on Form F-3 regulatory

"expressly incorporated by reference into the Company’s registration statement on Form F-3"

A registration statement on Form F-3 is a streamlined filing used by eligible foreign companies to register securities for sale in the U.S., often as a “shelf” that lets them offer shares quickly when market conditions are right. For investors it matters because it signals that the company can raise capital on short notice—potentially increasing liquidity but also the risk of share dilution if new stock is issued—similar to a company keeping a pre-approved credit line ready to use.

forward-looking statements regulatory

"This report includes forward-looking statements within the meaning"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
