Overview CACI International Inc (CACI), a Delaware corporation, is a holding company whose operations are conducted through subsidiaries primarily located in the U.S. and Europe. CACI was founded in 1962 as a simulation technology company and has grown into a leading provider of differentiated Technology and distinctive Expertise to customers in support of national security in the intelligence, defense, and federal civilian sectors, both domestically and internationally. Unless the context indicates otherwise, the terms “CACI,” the “Company,” “we,” “us,” and “our,” refer to CACI International Inc and its subsidiaries and joint ventures that are majority-owned or otherwise controlled by it. The term “the Registrant” refers to CACI International Inc only. •Technology – CACI provides technology that addresses our customers’ most challenging needs. This includes agile software development using open modern architectures and DevSecOps; advanced data platforms, applications, and analytics augmented by Artificial Intelligence (AI), Enterprise Resource Planning systems, electromagnetic spectrum capabilities, space-based sensors and ground site processors, photonics, and network modernization. CACI invests ahead of customer need with research and development (R&D) to create unique and differentiated technology addressing critical national security needs. •Expertise – CACI delivers talent with the specific technical and functional knowledge to support agency operations. Examples include individuals with talents such as software development, data and business analysis, operations support, naval architecture, engineering, life cycle support, intelligence and special operations support, and network exploitation analysis. Our proven Technology and Expertise and strong record of program delivery have enabled us to compete for and secure new customers and contracts, win repeat business, and build and maintain long-term customer relationships. We seek competitive business opportunities and have built our operations to support major programs through a market-focused business development organization. Our customers are primarily agencies and departments of the U.S. government as well as foreign governments and commercial enterprises. The demand for our Technology and Expertise is largely driven by the evolving national security and geopolitical environment, the increasingly complex network, systems, and information environments in which governments and businesses operate, and the ongoing need to stay current with emerging technology. For additional discussion and analysis on recent business developments, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of this Annual Report on Form 10-K.

Domestic Operations represented 96.8%, 97.0%, and 97.0% of our total revenues for the fiscal year ended June 30, 2026 (fiscal 2026), June 30, 2025 (fiscal 2025) and June 30, 2024 (fiscal 2024), respectively. International Operations Our International Operations are conducted primarily through our operating subsidiaries in Europe, CACI Limited and CACI BV, and account for substantially all revenues generated from international customers. Headquartered in London, our International Operations provide a diverse mix of IT services and proprietary data and software products, serving commercial and government customers throughout the U.K., continental Europe, and around the world. International Operations represented 3.2%, 3.0%, and 3.0% of our total revenues for fiscal 2026, 2025, and 2024, respectively. Competition We operate in a highly competitive industry that includes many competitors, some of which are larger in size and have greater financial resources than we do. We obtain much of our business on the basis of proposals submitted in response to requests from potential and current customers, who generally receive proposals from other firms. Non-traditional players have entered the market and have established positions related to such areas as cloud computing, cyber, satellite operations, and business systems. Additionally, we face indirect competition from certain government agencies that perform services for themselves similar to those marketed by us. We know of no single competitor that is dominant in our fields of technology. We have a relatively small share of the addressable market for our Technology and Expertise and intend to achieve growth and increase market share both organically and through strategic acquisitions. Strengths and Strategy We primarily offer our entire range of Technology and Expertise to defense, intelligence, and civilian agencies of the U.S. government. We also contract through our International Operations to provide our offerings to governments of other nations. As with other government contractors, our business is subject to government customer funding decisions and actions that are beyond our control. Our international commercial customer base consists primarily of large commercial and government enterprises in the U.K. This market is the primary target of a diverse mix of IT consultancy services and proprietary data and software products. Commercial bids are frequently negotiated as to terms and conditions for schedule, specifications, delivery, and payment. In order to effectively perform on our existing customer contracts and secure new customer contracts within the U.S. government, we must maintain expert knowledge of agency policies, operations, and challenges. We combine this comprehensive knowledge with Technology and Expertise for our customers. Our capabilities provide us with opportunities either to compete directly for, or to support other bidders in competition for, multi-million dollar and multi-year award contracts from the U.S. government. We have strategic business relationships with a number of companies across the industry. These strategic partners have business objectives compatible with ours and offer Technology and Expertise that complement ours. We intend to continue development of these kinds of relationships wherever they support our growth objectives. Our marketing and new business development is conducted by many of our officers and managers including the Chief Executive Officer (CEO), executive officers, vice presidents, and division managers. We employ business development professionals who identify and qualify major contract opportunities, primarily in the federal government market. Much of our business is won through submission of formal competitive bids. Government and commercial customers typically base their decisions regarding contract awards on their assessment of the quality of past performance, responsiveness to proposal requirements, price, and other factors. The terms, conditions, and form of contract of government bids, however, are in most cases specified by the customer. In situations in which the customer-imposed contract type or terms appear to expose us to inappropriate risk or do not offer us a sufficient financial return, we may negotiate alternate arrangements or opt not to bid for the work. Essentially all contracts with the U.S. government, and many contracts with other government entities, permit the government customer to terminate the contract at any time for the convenience of the government or for default by the contractor. Although we operate under the risk that such terminations may occur and have a material impact on operations, they have been rare and, generally, have not materially affected operations. Our contracts and subcontracts are composed of a wide range of contract types, including fixed-price, cost reimbursement, time-and-materials, Indefinite Delivery/Indefinite Quantity (IDIQ), and Government Wide Acquisition Contracts (known as GWACS) such as General Services Administration (GSA) schedule contracts. By company policy, significant fixed-price contracts require the approval of at least two of executives. For fiscal 2026, the top ten revenue-producing contracts, many of which consist of multiple task orders, accounted for 22.5% of our revenues, or $2.2 billion. 5 Recent Acquisitions During the past three fiscal years, we completed a total of eight acquisitions, including: •During fiscal 2026, the Company completed two acquisitions that enhanced our ability to deliver advanced technology for our national security customers in the space domain and to provide specialist data and cloud migration services to government clients. •During fiscal 2025, the Company completed three acquisitions that expanded our software-defined offerings, specialized technologies, and customer presence. •During fiscal 2024, the Company completed three acquisitions that enhance our capabilities and customer relationships. Seasonal Nature of Business Our business is generally not seasonal. Variations in our business also may occur at the expiration of major contracts until such contracts are renewed or new business is obtained. The U.S. government’s fiscal year ends on September 30 of each year. It is not uncommon for government agencies to award extra tasks or complete other contract actions in the weeks before the end of a fiscal year in order to avoid the loss of unexpended funds. Moreover, in years when the U.S. government does not complete the budget process for the next fiscal year before the end of September, government operations, whose appropriations legislation has not been signed into law, are funded under a continuing resolution (CR) that authorizes them to continue to operate but traditionally does not authorize new spending initiatives. Human Capital Our People Our employees are our most valuable resource. We are in continuing competition for highly skilled professionals in all of our market areas. The success and growth of our business is significantly correlated with our ability to recruit, train, promote, and retain high quality people at all levels of the organization. As of June 30, 2026, we employed approximately 27,000 talented full and part-time employees that help make CACI a respected and recognized industry leader. Our Culture Our culture defines who we are, how we act, and what we believe to be the right way to conduct business. It is the driving force behind our success. Our culture unifies us as a company and strengthens our resolve to meet our customers’ – and our country’s – most critical missions. We believe that there are two pillars to our culture: Character and Innovation. Character is demonstrated in our commitment to ethics and integrity as we expect all of our employees and independent contractors to comply with our high standards for the conduct of our business that are reflected in our policies and practices. We require all of our employees, including officers and directors, as well as independent contractors working on customer engagements, to execute and affirm to the code of ethics applicable to their activities annually. In addition, we require annual ethics and compliance training for all of our employees to provide them with the knowledge necessary to maintain our high standards of ethics and compliance. Innovation is demonstrated in our dedication to advancement and excellence. Our Center for Research, Application, Development, Learning, and Engagement (CRADLE℠) is a state-of-the-art collaboration facility that provides customers with an enhanced engagement experience, built to foster innovation, creative designs, and unique solutions. The CRADLE℠ brings together customers, industry partners, academia, and CACI personnel to explore and discover new ways to solve complex problems and challenges. Talent Acquisition, Development, and Retention Our industry is ever-evolving, and those who are most successful evolve with it, continually learning and growing throughout their careers. To ensure we have the talent to meet the needs of our customers, we employ broad recruiting and outreach efforts, including partnerships with universities, the military, and professional organizations, resulting in an inclusive pool of the most qualified candidates. We are able to retain our employees through our career mobility corporate culture, where we believe in growth at all levels. We encourage all employees to embrace a career growth mindset at CACI and strive to provide our employees with long-term professional advancement and a great workplace experience through professional development and a culture of mobility because our people drive our company. CACI has conducted employee engagement surveys, and we rank above external benchmark companies in the areas of sustainable engagement, inclusion, teamwork, supervision, and empowerment. Specifically, our employees report that they have a personal sense of accomplishment in their work, they feel safe to speak up, and they have pride in CACI. These indicators of an exceptionally strong culture and work environment puts CACI in an extremely competitive position to attract and retain talent and reach our organizational growth objectives. We continue to invest in the areas that produce such high engagement – leadership education, career resources for employees, comprehensive onboarding for new employees, and formal and informal communications that create a two-way dialogue among employees and leaders. We have a multilevel approach to developing our leaders, with cohort-style programs for first-line, mid-level, and executive leaders. These programs focus on leadership capabilities unique to each level of leadership and serve to increase self-awareness, strengthen skills, and expand networking for our leaders. Furthermore, we have a robust talent planning approach to identify potential future leaders, conduct rigorous assessments, and create actionable development plans to advance their readiness to take on our most senior roles as they evolve in our future. 6 Employee Wellbeing We value the social, physical, financial, and emotional well-being of our employees. We believe in curating environments and providing resources that support the CACI community’s well-being. We cultivate a culture that prioritizes wellness and encourages a healthy, balanced, and thriving lifestyle. It is our desire to provide our employees innovative and accessible resources that support them on their well-being journey to become their best selves. Our mission is to educate, support, and empower employees through the delivery of a comprehensive well-being program. Our well-being program includes Flexible Time Off, which allows employees to better balance their work and personal commitments by providing them the opportunity to take time off as needed without a set number of maximum days per year. In addition, CACI supports the financial wellness of our employees by providing unlimited access to fiduciary advice at no cost to the employee, as well as a full suite of tools and educational opportunities to enable our employees to meet their financial goals. Patents, Trademarks, Trade Secrets and Licenses Generally, our solutions and services are not substantially dependent upon obtaining or maintaining Intellectual Property (IP) protections, although our operations make use of such protections and benefit from them as discriminators in competition. The Company owns patents and claims copyright, trademark, and other proprietary rights in a variety of IP. We also maintain a number of trade secrets that contribute to our success and competitive distinction and endeavor to accord such trade secrets protection adequate to ensure their continuing availability to us. Our proprietary information is protected through a combination of contractual arrangements with our employees and third parties and IP laws. From time to time, we are required to assert our rights against former employees or other third parties who attempt to misappropriate our proprietary and confidential information. Although we are not materially dependent on the protection of our IP, we take such matters seriously and pursue claims against such individuals to the extent necessary to adequately protect our rights. It is important that we maintain access to software, data, and technology supplied by third parties, and we continue to enter into agreements that give us the right to distribute and receive income from third party software, data, and technology that serve our customers. The durations of such agreements are negotiated and vary according to the terms of the agreements.
