ICON plc determined that its previously issued audited financial statements for 2023 and 2024 and unaudited quarterly results through September 30, 2025 should no longer be relied upon, following an Audit Committee investigation into accounting practices and controls.
The investigation found issues primarily in revenue recognition, with revenue overstated in 2023 and 2024 by amounts below the previously indicated upper limit of 2%, and smaller impacts in 2025. ICON plans to restate these periods in its upcoming 2025 Form 20-F and an amended Form 6-K, which will also describe identified material weaknesses and remediation plans.
The company stated there was no impact on customers, operations or cash flow, and emphasized that referenced 2025 financial results are preliminary estimates that may change, potentially materially, once the audit and 2025 consolidated financial statements are completed.
