Argan, Inc. generates its primary revenue streams through large-scale, long-term engineering, procurement, and construction (EPC) contracts for power generation and industrial facility clients. By providing end-to-end management of complex building projects—including site development, technical engineering design, equipment procurement, and facility commissioning—the company earns significant contractual fees. Additionally, it secures reliable, ongoing revenue through professional operations and maintenance service agreements that extend well beyond the initial facility construction phase.
