Atos Group

Message from Philippe Salle,

Chairman and chief executive officer

Philippe Sallet

A new chapter of AI-driven growth is unfolding before us, and we are ready.

Dear Madam, Dear Sir, Dear shareholder,

The year 2025 marked a decisive turning point for our Group, confirming the relevance of the discipline, strategic clarity and transformation initiated under the Genesis plan. We met or exceeded our financial targets, improving the Group’s profitability and cash generation. We restored our operational foundations with a more resilient, and performance-driven operating model. Major commercial wins, industry recognition and strong market positions reflect renewed and growing client confidence across our businesses.

In a world being rapidly reshaped by AI acceleration, cybersecurity imperatives, and digital sovereignty, we have a unique business opportunity. We are stepping forward to expand our role as a trusted mission-critical technology partner. Our AI-first operating model powered by four newly launched agentic studios, the rapid ramp-up of our Data & AI workforce and the launch of our new consulting brand, positions us to support clients in adopting AI at scale, securely and responsibly. As we enter 2026, Atos Group is fundamentally transformed: more focused, more competitive and more agile. A new chapter of AI‑led growth is now opening and we are ready. The future doesn’t wait... neither do we.

Thank you for your loyalty and your trust.

Philippe Salle,
Chairman and chief executive officer

Atos has once again been awarded the coveted EcoVadis Platinum Medal for its Corporate Social Responsibility (CSR) performance, with an improved score of 84 out of 100.

Shareholders’ corner

One question, one answer

How should we interpret the change in Fitch's rating, which in December raised its outlook on Atos to positive and confirmed its rating at “B-”?

This update reflects Fitch’s confidence in our ongoing transformation and financial progress.

Several factors led to this update:

  • Improving financial health: Expected sequential growth in EBITDA margin and free cash flow.
  • Stronger financial resilience: Anticipated increase in interest cover.
  • Robust liquidity: Providing a solid foundation for our restructuring efforts and long-term stability.

This recognition underscores the progress made in the execution of Atos Group’ strategic and transformation plan, called Genesis, aimed at strengthening our financial profile, operational performance, and long-term sustainability.
