ClearPath® Forward Overview Chris Arrasmith Chief Operating Officer Sean Tinney SVP and GM Enterprise Computing Solutions Investor Presentation

Disclaimer Forward-Looking Statements This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Unisys cautions readers that the assumptions forming the basis for forward-looking statements include many factors that are beyond Unisys’ ability to control or estimate precisely, such as estimates of future market conditions and the behavior of other market participants. Words such as “anticipates,” “estimates,” “expects,” “projects,” “may,” “will,” “intends,” “plans,” “believes,” “should” and similar expressions may identify forward-looking statements and such forward-looking statements are made based upon management’s current expectations, assumptions and beliefs as of this date concerning future developments and their potential effect upon Unisys. There can be no assurance that future developments will be in accordance with management’s expectations, assumptions and beliefs or that the effect of future developments on Unisys will be those anticipated by management. Forward-looking statements in this presentation include, but are not limited to, any projections or expectations of revenue growth, margin expansion, investments in our solutions and artificial intelligence adoption and innovation, L&S revenue, economic conditions or performance. Additional information and factors that could cause actual results to differ materially from Unisys’ expectations are contained in Unisys’ filings with the U.S. Securities and Exchange Commission (SEC), including Unisys’ Annual Reports on Form 10-K and subsequent Quarterly Reports on Form 10-Q, recent Current Reports on Form 8-K, and other SEC filings, which are available at the SEC’s web site, http://www.sec.gov. Information included in this presentation is representative as of the date of this presentation only and while Unisys periodically reassesses material trends and uncertainties affecting Unisys’ results of operations and financial condition in connection with its preparation of management's discussion and analysis of results of operations and financial condition contained in its Quarterly and Annual Reports filed with the SEC, Unisys does not, by including this statement, assume any obligation to review or revise any particular forward-looking statement referenced herein in light of future events, except as required by applicable law. Non-GAAP Information This presentation includes certain non-GAAP financial measures that exclude certain items such as postretirement expense; debt extinguishment, certain legal and other matters related to professional services and legal fees, including legal defense costs, associated with certain legal proceedings; environmental matters related to previously disposed businesses; and cost-reduction activities and other expenses that the company believes are not indicative of its ongoing operations, as they may be unusual or non-recurring. The inclusion of such items in financial measures can make the company’s profitability and liquidity results difficult to compare to prior periods or anticipated future periods and can distort the visibility of trends associated with the company’s ongoing performance. Management also believes that non-GAAP measures are useful to investors because they provide supplemental information about the company’s financial performance and liquidity, as well as greater transparency into management’s view and assessment of the company’s ongoing operating performance. Non-GAAP financial measures are often provided and utilized by the company’s management, analysts, and investors to enhance comparability of year- over-year results. These items are uncertain, depend on various factors, and could have a material impact on the company's GAAP results for the applicable period. These measures should not be relied upon as substitutes for, or considered in isolation from, measures calculated in accordance with U.S. GAAP. A reconciliation of these non-GAAP financial measures to the most directly comparable financial measures calculated and reported in accordance with GAAP can be found below except for financial guidance and other forward-looking information since such a reconciliation is not practicable without unreasonable efforts as the company is unable to reasonably forecast certain amounts that are necessary for such reconciliation. This information has been provided pursuant to the requirements of SEC Regulation G.

ClearPath® Forward Why is ClearPath® Forward So Persistent? Replicating the CPF environment is costly and introduces significant migration risks Migration Challenges Mission-critical Platform Powers the most demanding, mission-critical business processes that delivers unmatched reliability, security, and performance where downtime is not an option Continuous Innovation Constantly evolving, with new features, integrations, and support for modern programming languages, AI, quantum, and cloud deployment options Expanding Ecosystem Easier to integrate with client environments, cloud services, third-party tools, allowing clients to accelerate digital initiatives Simplified Management Modern system tools and automation make it easier to administer and maintain the platform Embedded Processes Deeply integrated into client workflows, creating seamless alignment between business and the technology With migration failures commonplace, successful migrations typically take over a decade to complete with no guarantee of replicating the security, performance, scalability, and resilience of the CPF modern ecosystem. Application Modernization Rarely matches reliability and performance of original environment and often requires costly rewrites, loss of embedded business logic, and significant risk of operational disruption Data Migration Requires restructuring to maintain security, speed, and integrity which can be costly and introduce vulnerabilities or disrupt business continuity Infrastructure Integration Migration often integrating multiple platforms and technologies, increasing integration complexity and operational overhead Program and Change Management Costs Demand significant time, resources, and budget, typically exceeding estimates and delivering uncertain returns while also requiring clients to fundamentally reengineer embedded business processes Business and Security Risk Introduces operational risk, potential data loss, compliance gaps, and new security vulnerabilities Run Costs Typically, more expensive to replicate ClearPath® Forward’s built-in efficiency, resilience, and optimized workload management
