Growth through acquisitions Recent and multiple acquisitions in 2026 (Ott Consulting Inc. and Mountain Research Inc. plus Ott Consulting earlier) indicate ARRO is actively expanding its service footprint, which creates opportunities to cross-sell engineering, environmental compliance, GIS, and planning solutions to new client bases and industries.

Regional expansion With 12 offices across the Mid-Atlantic and a 80-year track record in municipal engineering, ARRO’s regional scale suggests opportunities to win larger, multi-site projects, public-sector contracts, and recurring maintenance programs from municipalities and water/wastewater systems.

Financial capacity Reported revenue in the broad $50M–$100M range and a professional services profile position ARRO as a mid-market engineering firm capable of undertaking sizable, multi-year programs, potentially appealing to clients seeking partner firms with stability and scale.

Tech-enabled delivery Adoption of tools like Google Cloud, Power Apps, Webflow, and other tech platforms indicates a modern delivery approach; sales opportunities exist to partner on digital transformation, GIS integration, data analytics, and streamlined project delivery for municipalities.

Leadership and continuity A history of leadership promotions and a CFO appointment reflects organizational maturity and governance; sales conversations can emphasize reliability, long-term partnerships, and consistent project outcomes with a firm that has established executive stability.
