FY 2025 performance highlights

*: at constant scope and December 2025 average exchange rates

Operational performance

On a full-year basis, Group revenue reached €8,001 million – or €8,030 million at September 30 currency – in line with the previously communicated target of “above €8 billion⁴”. Atos SBU generated revenue of €6,963 million, down -16.2% organically compared to FY 2024. The Eviden SBU revenue was up +6.7% compared to FY 2024, to €1,039 million in FY 2025.

Group operating margin reached €351 million in FY 2025 – or 4.4% of revenue (compared to 1.9% in FY 2024), above the previously communicated target of “around €340 million or above 4%”. This represents 104% organic growth year-on-year, despite a €1,282 million organic revenue decline. This performance demonstrates the benefits of the cost reduction measures implemented since the beginning of the year under the Genesis transformation plan.

 *: at constant scope and December 2025 average exchange rates

Atos – Germany, Austria & Central Europe revenue totaled €1,504 million in FY 25, representing a -9.7% organic decline compared to FY 2024, with a few large client-ramp downs following insourcing strategies. It also stemmed from managed exits from low-profitability contracts. That was partially offset by successful fertilization, cross-selling to existing clients and the acquisition of new clients.

Operating margin improved by 269 basis points (bps) year-on-year, driven by the restructured delivery of the existing contract portfolio and benefits from Genesis-driven cost-cutting initiatives.

Atos – North America revenue was €1,266 million in FY 2025, representing a -27.9% organic decline compared to FY 2024. This decrease was mostly driven by 2024 contract exit decisions related to the Group’s financial situation before successful financial restructuring, as well as a net scope reduction among existing clients. The business has not yet benefited from improving commercial momentum, although signs of recovery are emerging with growing order entry and some ramp-ups.

Operating margin improved by 193 bps compared to FY 2024 despite the material impact from revenue fall through, driven by the Genesis-led margin optimization actions already in place.

Atos – France revenue reached €1,140 million in FY 2025, down -10.3% organically from FY 2024, due to high exposure to a recently muted public sector market that led to a significant ramp down, as well as the impact of the financial restructuring process on client perception in 2024. 

Operating margin improved by 65 bps year-on-year despite declining revenues driven by the benefit of cost-cutting initiatives on indirect costs, an improved billability rate.

Atos – UK & Ireland revenue reached €1,128 million in FY 2025, down -23.0% organically year-on-year, mainly due to planned completion of large public sector Business Process Outsourcing (BPO) contracts in the fourth quarter of 2024. Subsequently, the fourth quarter has seen a return to organic growth (+2.5% yoy) supported by increased adoption of offerings among existing clients (notably with government clients), and new accretive revenue from new clients, especially in the financial services sector.

Operating margin improved by 159 bps compared to FY 2024. In absolute terms, it was stable year-on-year despite the sharp decrease in revenue due to the restructuring of low profitability contracts, successful delivery of new business and an already visible impact from cost-saving initiatives.

Atos – International Markets revenue was down -15.2% organically in FY 2025, to €1,112 million, mostly driven by softer performance in Asia Pacific, Switzerland and major events that benefited from the Olympics in fiscal year 2024.

Operating margin improved by 460 bps compared to FY 2024, doubling year-on-year in absolute terms. The contribution from lost revenue was more than offset by improved productivity, benefits from the Genesis transformation plan and lower one-off costs year-on-year with Olympics-related marketing costs incurred in fiscal year 2024.

Atos – BNN (Belux, Netherlands & Nordics) revenue stood at €801 million in FY 2025, down -3.5% organically compared to FY 2024, with churn partially offset by growing activity at existing clients.

Operating margin improved by 612 bps compared to FY 2024, to 6.9% in FY 2025, driven by the ramp down of lower profitability contracts, productivity improvement and positive impact from cost reduction initiatives.

Eviden revenue was €1,039 million in FY 2025, up 6.7% year-on-year, driven by the strong performance of the Advanced Computing activity with the delivery of the Jupiter supercomputer in the third quarter.

As a result, operating margin improved by 887 bps, reaching €48 million.

Global Structures costs stood at €-100 million in FY 2025, compared to -91 million euros in FY 2024 at constant scope and December 2025 average exchange rates.

Order Entry and Backlog

Commercial activity

In 2025, the Group carried out a comprehensive reset of its commercial organization to improve efficiency, increase accountability, and strengthen go-to-market performance. First benefits were already visible, particularly in productivity and pipeline quality.

Order entry reached €7,084 million in FY 2025, bringing the book-to-bill ratio to 89% vs 82% restated last year and indicating early signs of renewed client confidence. Main contract signatures in 2025 included:

• A Cybersecurity contract with the EU Commission
• A Digital Workplace contract with the UK Department for Environment, Food & Rural Affairs (Defra)
• A Cloud & Modern Infrastructure contract with a leading insurance company in North America
• The application of the extension of the customer relationship agreement with Siemens in Germany.

Renewal rate reached 92% in FY 2025, compared to 89% in FY 2024.

Backlog and commercial pipeline

At the end of December 2025, the full backlog reached €10.7 billion, representing 1.3 years of revenue. The full qualified pipeline amounted to €4.2 billion at the end of December 2025, representing 6.2 months of revenue and showing a year-on-year increase in key business lines, such as Digital Applications and Data & AI.  

Update on the Genesis plan Execution

At the Capital Markets Day held on May 14, 2025, the Group unveiled “Genesis”, its strategic and transformation plan for the next four years. It includes 22 workstreams regrouped under seven pillars:

• Growth
• Human Resources
• Countries review
• Portfolio review
• Gross Margin
• Cost review
• Cash

During 2025 significant progress was achieved with 88%⁵ of the three-year savings target completed with initiatives implemented during the year, including the following:

• Countries review: To sharpen the geographical focus, the Group exited or terminated commercial operations in ten countries and disposal processes led or will lead to the exit of seven more
• Contract portfolio review: The Group reduced its exposure to low margin contracts (i.e., contracts with a project margin below 5%) to c.€16 million negative impact on operating margin compared to c. €122 million in 2024.
• Delivery and general and administrative (G&A) optimization: The billability rate improved from 76% to 79% and the G&A cost base was reduced by 26% compared to 2024. Overall, over three quarters of the three-year restructuring envelope of 700 million euros was incurred during the year. The total headcount was 63,193 at the end of the period.

ESG Performance in 2025 and Beyond

Atos Group has delivered on the promise it made in 2019 and has achieved its near-term Science Based Targets initiative (SBTi) objective to reduce its 2025 emissions by 50% compared to 2019. Furthermore, the Group reaffirmed its commitment during its Capital Markets Day in May 2025, to further reduce its GHG emissions to be net-zero by 2050 compared to 2025 and as defined by the SBTi. Atos Group will continue to mobilize its resources to decrease GHG emissions in its own operations and its supply chain, as well as to develop solutions and services to support its clients’ decarbonization ambitions.
Atos Group set a target to reach 40% female representation among new hires by the end of 2025. While significant progress was made and the target was not fully achieved, the Group continues to strengthen its initiatives to improve gender balance.

Atos Group also recognizes its responsibility to support and actively shape the transformation towards artificial intelligence and has therefore developed a training program. In 2025, 73% of the Group had completed the AI Fluency program, a strong indicator of our workforce readiness for AI-driven transformation.

Atos Group’s ambitions for sustainable digital business are reflected in very good assessment results. The Group is proud to be included for the 13th consecutive year in the S&P Global Sustainability Yearbook, reaffirming the company’s longstanding commitment to responsible business practices and leadership in environmental, social and governance (ESG) performance. Atos Group’s most recent Corporate Sustainability Assessment (CSA) score is 73/100, positioning the Group among the strongest performers worldwide across ESG dimensions within its industry. 

In 2025, the company was included in CDP’s Climate “B List”, demonstrating performance above the global average in the management of climate related risks, governance, and strategic climate action. This result confirms the credibility and structure of Atos’ climate strategy.

Furthermore, Atos Group has once again been awarded EcoVadis Platinum Medal for its Corporate Social Responsibility (CSR) performance, with an improved score of 84 out of 100. This recognition places the Group in the top 1% of companies assessed by EcoVadis in its industry.

Acceleration of the Group’s Technological Ambition

Atos Group’s positioning in mission-critical, regulated, complex IT environments makes AI a structural opportunity for the Group. Rather than displacing core services, AI increases complexity, security requirements, compliance burdens, and integration demand — all areas where the group is deeply embedded.

The Group’s defensive characteristics — long-term client relationship, complex project management, cybersecurity expertise, and sovereign positioning — create resilience against AI disruption risk while offering upside through automation and higher-value AI-powered services.

Atos Group’s transformation is built on three mutually reinforcing tech‑strategic pillars — Agentic AI, Digital Sovereignty and Cybersecurity. Atos enters the AI‑first era with strong differentiators: deep partnerships, enterprise‑scale AI operations, mission‑critical expertise and secure‑by‑design delivery, enabling clients to move beyond proofs of concept and deploy AI in regulated, brownfield and operationally critical environments. AI becomes truly transformative when embedded into sovereign architectures and protected by advanced cyber capabilities, creating a self‑reinforcing flywheel where sovereignty ensures trust, cybersecurity ensures resilience and AI accelerates value creation.

In particular, Eviden – Atos Group branch providing security, cybersecurity and defense products and systems delivers deterministic, safety critical solutions — built on decades of expert data and robust command and control platforms, which remain unmatched for reliability. GenAI and agentic AI act as force multipliers, not replacements, expanding Eviden’s market through natural language control for non‑experts, context aware intelligence that enhances situational awareness, and optimized AI models deployable at the edge. With strong credentials in sovereignty and compliance, Eviden is positioned to provide safer, more resilient, and more predictive critical systems while remaining a trusted integrator for uptime, safety, and regulatory assurance.

Since 2025, Atos Group operationalized this strategy by appointing a new CTO, creating a dedicated Data & AI business line, developing workforce skills and launching a full portfolio redesign built around agentic AI, digital sovereignty and cybersecurity. It is now further accelerating industrialization through the launch of Atos Sovereign Agentic Studios in the U.S., the UK, France and Germany, enabling safe, governed, production‑grade AI agents embedded directly into clients’ operations and designed to scale autonomous execution, secure orchestration and software‑driven delivery for mission‑critical environments.

Atos Group also launched Atos Amplify, a unified AI‑powered consulting business unit designed to accelerate client transformation by combining deep industry expertise, advanced technology capabilities, and a strong focus on AI, cybersecurity and digital sovereignty. With a proven track record across major European and global clients, Atos Amplify brings an AI‑ready consult‑to‑build model that delivers tangible business outcomes, integrating Atos’ people, processes and assets with responsible AI guardrails to ensure secure, tailored and high‑impact transformation at scale.

Together, these moves position Atos to accelerate its development in the AI era with a robust, sovereign and secure foundation.

Human Resources

The total headcount was 63,193 at the end of December 2025, a decrease of -19.1% compared with the end of December 2024 essentially as a result of the execution of the Genesis headcount reduction program.

During the year, the Group hired 6,041 staff (of which 92.4% were direct employees), while attrition rate in FY 2025 was at 15.3% vs 15.6% in 2024.

Net income

Other Operating Income (OOI)
Other operating income and expenses amounted to €–1,179 million for full-year 2025, compared to –€2,858 million for full-year 2024. It mostly included restructuring and other non-recurring charges in relation to the Genesis transformation plan, as well as litigation and some onerous contracts provisions and asset impairment in the context of the disposal of Advanced Computing activities.
Financial income
Net financial expense was €-437 million for full-year 2025, compared to €3,121 million for full-year 2024, reflecting the new debt structure of the Group and the fair value adjustment of the net debt.

As a result of the above net result Group share was a loss of €–1,404 million for full-year 2025, compared to a win of €248 million for full-year 2024.

Net Change in Cash⁶

Net change in cash⁶ for the period stood at €-326 million euros for the period, in line with the previously communicated target of “better than €-350 million”, and reflecting the following items:

• Operating margin before depreciation and amortization (OMDA) of €883 million
• Capex of €-170 million, or 2.1% of revenues
• Leases paid for €-278 million
• Change in working capital requirement (excluding WCA) of €33 million, mostly driven by lower activity in 2025
• Cash restructuring of €-445 million, mostly in relation to the Genesis transformation plan
• Tax paid of €-31 million
• Net cash cost of debt of €–160 million, including €34 million of financial income
• Other items for €–157 million, which included litigation and onerous contracts

Net Debt and Debt Covenants

At December 31, 2025, net debt was €1,843 million (€945 million including IFRS 9 debt fair value adjustment), compared to €1,238 million as of December 31, 2024 (€275 million including IFRS 9 debt fair value adjustment), and mainly consisted of:

• Cash and cash equivalents for €1,265 million
• Borrowings for €3,064 million (nominal value, excluding PIK) or €2,285 million including IFRS 9 fair value adjustment and PIK. The Group is considering the possibility of repurchasing bond debt on the market. It will evaluate any such transaction in the future in light of existing market conditions.

The credit documentation requires the Group to maintain:

• A minimum liquidity level of €650 million, to be verified at the end of each financial quarter starting March 31, 2025.
• A maximum level of financial leverage (“Total Net Leverage Ratio Covenant”), applicable from 30 June 2027, as from each half-year end, which is defined as the ratio of financial indebtedness (mainly excluding IFRS 16 impacts and IFRS 9 debt fair value treatment) to pre-IFRS 16 OMDA; the ceilings thus applicable will be determined no later than 30 June 2026 with reference to a flexibility of 30% in relation to the Business Plan adopted by the Group at that time; these ceilings will in any event remain between 3.5x and 4.0x

As of December 31, 2025, the Group’s financial leverage ratio (as defined in the glossary) was 3.17x.

Outlook

Following the disposal of Advanced Computing activities, the Ideal GRP subsidiary in the Nordics and the Atos operations in South America, the Group’s baseline for establishing future ambition represented revenues and operating margin of €7,187 million and €314 million respectively⁷ in FY 2025.

From this baseline, in 2026, the Group anticipates a year of stabilization and aims to deliver:

• positive organic growth, with a downside scenario limited to –5% in a challenging market environment
• an operating margin of around 7%
• positive net change in cash⁸ before debt repayment, M&A and at constant currency.

The Group foresees an acceleration of profitable growth and cash generation to accelerate in 2027 and in 2028. Assuming the disposal of Advanced Computing in FY 2026 and a progressive reduction of its geographic footprint, the Group expects:

• To generate organic revenue CAGR of 5 to 7% between 2026 and 2028. Strategic, targeted and disciplined M&A could further increase revenue over the period
• To reach an operating margin of around 10% in FY 2028, supported by cost reduction measures and profitable growth, partially offset by an acceleration of R&D investments
• To achieve a leverage ratio below 1.5x net debt/OMDAL⁹ in fiscal year 2028. On the path to an investment grade rating, the Group expects to achieve a BB profile in 2027.

Restatement corresponds to the transfer of Cybersecurity Services from Eviden to Atos.

Scope effects on revenue amounted to €-148 million and €-17 million on operating margin. They are mainly related to the divestiture of Worldgrid in France, International Markets (Iberia) and Germany.

Currency effects contributed negatively to revenue for €-144 million and €-10 million on operating margin. They mostly came from the depreciation of the US dollar, the British pound, the Brazilian real, the Argentinian peso and the Turkish lira.

In accordance with IFRS 5, the Group determined that the asset group related to the contemplated disposal of “Advanced Computing” activities met the criteria to be classified as assets held for sale, given the advanced stage of negotiations with the French State and the expected completion of the transaction during the first half of 2026.

Furthermore, these activities held for sale were not classified as discontinued operations in the income statement within the meaning of IFRS 5, as they do not represent a major and separate line of business for the Group.

Glossary

Operational capital employed: Operational capital employed comprises net fixed assets and net working capital but excludes goodwill and net assets held for sale.

Current and non-current assets or liabilities: A current and non-current distinction is made between assets and liabilities on the consolidated statement of financial position. Atos has classified as current assets and liabilities those assets and liabilities that Atos expects to realize, use or settle during its normal cycle of operations, which can extend beyond 12 months following the period end. Current assets and liabilities, excluding the current portion of borrowings, lease liabilities and provisions, and current financial instruments represent the Group’s working capital requirement.

DSO: (Days of Sales Outstanding). DSO is the amount of trade accounts receivable (including contract assets) expressed in days of revenue (on a last-in, first-out basis). The number of days is calculated in accordance with the Gregorian calendar.

Organic growth: Organic growth represents the percent growth of a unit based on a constant scope and exchange rates basis.

CAGR: The Compound Annual Growth Rate reflects the mean annual growth rate over a specified period of time longer than one year. It is calculated by dividing the value at the end of the period in question by its value at the beginning of that period, raise the result to the power of one divided by the period length, and subtract one from the subsequent result. As an example:

2019-2021 revenue CAGR = (Revenue 2021 / Revenue 2018) (1/3) -1

Operating margin: Operating margin equals to External Revenues less personnel and operating expense. It is calculated before Other operating income and expense as defined below.

Other operating income and expense: 

Other operating income and expense include:

• The amortization and impairment of intangible assets recognized as part of business combinations such as customer relationships, technologies and goodwill
• When accounting for business combinations, the Group may record provisions in the opening statement of financial position for a period of 12 months beyond the business combination date. After the 12-month period, unused provisions arising from changes in circumstances are released through the income statement under “Other operating income and expense”
• the cost of acquiring and integrating newly controlled entities, including earn out with or without presence conditions
• the net gains or losses on disposals of consolidated companies or businesses
• the fair value of shares granted to employees including social contributions
• the restructuring and rationalization expense relating to business combinations or qualified as unusual, infrequent and abnormal. When a restructuring plan qualifies for Other operating income and expense, the related real estate rationalization & associated costs regarding premises are presented on the same line
• the curtailment effects on restructuring costs and the effects of plan amendments on defined benefit plans resulting from triggering events that are not under control of Atos management
• the net gain or loss on tangible and intangible assets that are not part of Atos core-business such as real estate
• other unusual, abnormal and infrequent income or expense such as major disputes or litigation.

Gross margin and indirect costs: Gross margin is composed of revenue less the direct costs of goods sold. Direct costs relate to the generation of products and/or services delivered to customers, while indirect costs include all costs related to indirect staff (defined hereafter), which are not directly linked to the realization of the revenue. The operating margin comprises gross margin less indirect costs.

EBITDA (Earnings Before Interest, Tax, Depreciation and Amortization): For Atos, EBITDA is based on Operating Margin less non-cash items and is referred to as OMDA (Operating Margin before Depreciation and Amortization).

OMDA (Operating Margin before Depreciation and Amortization) is calculated as follows:

Operating margin, plus:

• Depreciation of fixed assets (as disclosed in the “financial report”);
• Depreciation of right of use (as disclosed in the “financial report”);
• Net book value of assets sold/written of (as disclosed in the “financial report”);
• Net charge (release) of provisions (composed of net charge of provisions for current assets and net charge of provisions for contingencies and losses, both disclosed in the “financial report”);
• Net charge (release) of provisions for pensions (as disclosed in the “financial report”).

OMDAL: OMDA – lease repayments.

Gearing: The proportion, expressed as a percentage of net debt to total shareholders’ equity (Group share and minority interests).

Interest cover ratio: Operating margin divided by the net cost of financial debt, expressed as a multiple.

Leverage ratio: Net debt (before IFRS 9 fair value adjustment) / OMDAL last 12-months

Operating income (loss): Operating income (loss) comprises net income (loss) before deferred and current income taxes, net financial income (expense), and share of net profit (loss) of equity-accounted investments.

Cash flow from operations: Cash flow coming from the operations and calculated as a difference between OMDA, net capital expenditures, lease payment and change in working capital requirement.

Net cash or net debt: Net cash or net debt comprises total borrowings (bonds, short-term and long-term loans, securitization and other borrowings), short-term financial assets and liabilities bearing interest with maturity of less than 12 months, less cash and cash equivalents. Liabilities associated with lease contracts and derivatives are excluded from the net debt.

Free Cash Flow (FCF): The Free Cash Flow represents the change in net cash or net debt, excluding capital increase, share buyback, dividends paid to shareholders and non-controlling interests, net acquisition or disposal of companies.

Earnings (loss) per share (EPS): Basic EPS is the net income (loss) divided by the weighted-average number of common shares outstanding during the period. Diluted EPS is the net income (loss) divided by the diluted weighted-average number of common shares for the period (number of shares outstanding plus dilutive instruments with dilutive effect).

Revenue: Revenue related to Atos’ sales to third parties (excluding VAT).

TCV (Total Contract Value): The Total Value of a Contract at signature (prevision or estimation) over its duration represents the firm order and contractual part of the contract excluding any clause on the decision of the client, as anticipated withdrawal clause, additional option or renewal.

Order entry/bookings: The TCV, orders or amendments signed during a defined period. When an offer is won (contract signed), the total contract value is added to the backlog and the order entry is recognized.

Book-to-bill: The Book-to-Bill is the ratio expressed in percentage of the order entry in a period divided by revenue of the same period.

Backlog/Order cover: The value of signed contracts, orders and amendments that remain to be recognized over their contract lives. It may include revenue recognized on contracts based on the actual use of billable services such as volume-based considerations. It does not hence represent the transaction price allocated to performance obligations not yet satisfied (backlog) as defined by IFRS 15.

Pipeline: The value of revenues that may be earned from outstanding commercial proposals issued to clients. A qualified pipeline applies an estimated percentage likelihood of proposal success.

Direct Staff: Direct staff includes permanent staff and subcontractors, whose work is billable to a third party.
