Jacobs Solutions Inc. is a leading international technical professional services firm that delivers end-to-end solutions across the asset lifecycle. The company's business model centers on providing high-value advisory, engineering, architectural design, and program management services rather than physical construction. Following the 2024 spin-off of its Critical Mission Solutions and Cyber & Intelligence businesses to Amentum, Jacobs streamlined its operations into two primary segments. The Infrastructure & Advanced Facilities (I&AF) segment generates the vast majority of the company's revenue (approximately 89% in fiscal 2025) and provides integrated design, engineering, and lifecycle management services for sectors including life sciences, data centers, semiconductors, water, energy, and transportation. The PA Consulting segment (approximately 11% of revenue) offers high-end management consulting, innovation, and technology-enabled advisory services to diverse industries. Geographically, Jacobs operates in over 40 countries, with a significant footprint in North America, Europe, and the Asia Pacific/Middle East (APME) regions. The company's competitive position is bolstered by its shift toward higher-margin, technology-driven consulting and its strong backlog of government and commercial contracts focused on infrastructure modernization and sustainability.
