French IT giant Atos reported estimated Q4 2025 group revenue of €2,004 million, marking a 9.3 percent decline from Q4 2024. This downturn stemmed from 2024 contract losses, voluntary exits — particularly in the Atos Strategic Business Unit (SBU) — and a challenging IT services market. Despite headwinds, full-year revenue aligned with guidance at around €8 billion, Atos said.

Atos CEO Philippe Salle highlighted the organic decline of 13.8 percent for FY 2025 during a media call, attributing it to persistent contract erosion. Yet, positive signals emerged in order entry and regional momentum, signaling a potential turnaround for the debt-restructured firm.
Atos SBU and Eviden SBU Breakdown: Mixed Regional Performance
The Atos SBU, the company’s core IT services arm, posted Q4 revenue of €1,738 million — a 9 percent drop year-over-year. Quarter-on-quarter improvements shone in North America and the UK & Ireland, buoyed by stabilizing demand.
Eviden, Atos’ advanced computing and AI-focused unit, saw Q4 revenue fall 11.2 percent to €265 million, lacking a large high-performance computing (HPC) contract from the prior year.
On a full-year basis:
Atos SBU: €6,963 million, down 16.2 percent organically from FY 2024.
Eviden SBU: €1,039 million, up 6.7 percent organically—its lone bright spot amid group pressures.
These figures underscore Atos’ shift toward high-margin areas like AI and advanced computing while trimming low performers.
Strong Order Entry and Book-to-Bill Surge in Q4 2025
Atos notched Q4 order entry of €2,444 million, fueled by momentum in core business lines and advanced computing. Key regions like North America, Germany, and Benelux accelerated, aided by the Customer Relationship Agreement (CRA 2.0) with Siemens AG.
The group book-to-bill ratio hit 122 percent in Q4 2025, up 4 points from last year. Segment details:
Atos SBU: 106 percent, down 19 points due to tough comps post-2024 restructuring.
Eviden SBU: A stellar 229 percent, +156 points year-over-year, driven by the Alice Recoque supercomputer deal.
This commercial uptick hints at returning customer confidence, as Salle noted: “We can see customer confidence is gradually returning.”
Profitability Outlook and 2026 Roadmap: Exceeding Targets
Atos anticipates surpassing its FY 2025 operating margin goal, exceeding €340 million (over 4 percent of revenues). Long-term ambitions remain intact, with FY 2026 targets set for March 6, 2026, alongside audited FY 2025 results.
Post-debt restructuring — valued at €1 billion versus a €10 billion peak — Atos continues divestments, planning exits from 10 more countries in 2026 after Scandinavia and Latin America sales. Job cuts and asset disposals aim to streamline operations in telecom, digital transformation, and renewables-adjacent tech, Reuters news report said.
