IndustrialsIndustrial - Pollution & Treatment Controlsmoderate - The business has meaningful fixed costs in engineering staff, compliance expertise, and service infrastructure, but variable costs scale with project volume. As revenue grows, incremental margins should improve significantly (evidenced by 10% revenue growth driving 58% net income improvement). However, small scale ($100M revenue) limits negotiating power with suppliers and creates overhead burden.
