Growth through acquisitions ARRO has been actively expanding through acquisitions in 2026, including Mountain Research and Ott Consulting, signaling a growth strategy that likely increases service breadth, cross-selling opportunities, and geographic footprint in the Mid-Atlantic.

Strong regional footprint Headquartered in Lancaster County with twelve offices serving the Mid-Atlantic suggests a robust regional presence ideal for sales outreach, partnership opportunities, and localized project pipelines across municipal engineering, water, and environmental services.

Public sector focus ARRO’s core offerings in municipal engineering, water and wastewater, stormwater, GIS, planning, and environmental compliance align with public sector funding cycles and infrastructure modernization programs, presenting recurring project opportunities with government agencies.

Financially solid With estimated revenue between 50 and 100 million dollars and a multi-decade operating history, ARRO presents a stable, mid-market target for strategic partnerships, retained services, and long-term advisory engagements.

Technical capabilities Proficiency in Autodesk AutoCAD Civil 3D, GIS, and modern tech stack (Python, PHP, API-ready tools) positions ARRO to pursue digital transformation, data-driven planning, and infrastructure modernization projects, enabling cross-sell of technology-enabled services.
