Endava CFO Placed on Leave Amid 25% Stock Plunge; Governance Risk Compounds Turnaround Doubt

What happened

On September 22, 2026, Endava announced its CFO was placed on leave, triggering a >25% share decline and raising concerns over management integrity and accounting practices. This development compounds existing operational struggles: revenue contracted 5.9% YoY in Q2 FY2026, adjusted EBITDA margin fell to 5.8%, and the AI-native pivot (Dava.Flow) remains unproven with only two live engagements. The board's action suggests potential deficiencies in financial reporting or internal controls, contradicting the company's prior assertions of effective SOX-like controls in its FY2025 20-F. With net debt of $168.7 million (2.5x EBITDA) and interest coverage of 2.2x, any restatement or extended uncertainty could strain liquidity and violate covenants. Investors now face a dual risk: operational fragility plus governance failure, which may delay the validation of margin recovery and revenue stabilization that were prerequisites for a re-rating.

Implication

The CFO leave likely precedes an internal investigation or audit; watch for delayed filings or restatements. Key metrics to monitor: Q3 FY2026 revenue vs guided £182-185M range, any changes to guidance or disclosures around AI partnership costs. The bear case probability rises as governance risk adds to margin and growth concerns; fair value may fall below previous $3 bear case. If the investigation clears without restatement, the stock may rebound, but the damage to management credibility will linger. Until there is clarity, the stock is uninvestable for most long-only mandates; only high-risk traders should consider speculative positions.

Thesis delta

The investment thesis degrades from 'wait for operating proof points' to 'avoid until accounting integrity is re-established.' The CFO placement on leave directly contradicts the prior report's assumption of effective internal controls and adds a binary event risk (possible restatement) that was not previously priced. Consequently, the probability-weighted value shifts towards the bear case, and the recommended action changes from WAIT to AVOID/EXIT until the board completes its review and publishes clean findings.
