Background

Reanda Audit & Assurance B.V. is an Amsterdam-based member firm of Reanda International and has audited Nebius Group N.V.'s annual accounts since 2024.

In the FY2025 20-F filed 30 April 2026, Reanda gave an adverse opinion on Nebius's internal control over financial reporting, having done the same for FY2024. The finding covered controls over fixed-asset depreciation start dates and asset-count reconciliation, including server and network equipment. Reanda's opinion on the financial statements themselves was unqualified: the numbers were not qualified, the process producing them was. The filing records no disagreement between Reanda and Nebius over accounting principles, disclosure or audit scope.

Nebius's board approved Reanda's dismissal in February 2026, effective once Reanda completes the FY2025 audit and the Q1 2026 review and shareholders approve a successor at the 2026 AGM. The board has so FAR only resolved to recommend Deloitte & Touche LLP to that meeting; Deloitte is nominated, not appointed.
