Reliant Asset Management

What Reliant Asset Management does

Reliant Asset Management is a specialty rental company that provides modular space solutions to enterprise and government customers across North America. Founded in 2003 by brothers Michael and Barry Roman, the company finances, manufactures, transports, constructs, and leases both relocatable and permanent modular buildings through a network of subsidiaries including Aries Building Systems, Advanced Modular Space, Class Leasing Inc., Aries Residence Suites, Bakken Residence Suites, Watford Place, RAM Modular Canada, and Aries PNW. Its customer base spans the energy sector (oil and gas workforce housing near the Bakken and Eagle Ford formations), education (DSA-approved relocatable classrooms for California school districts), healthcare, government, and commercial businesses.

The company's core product is factory-built commercial modular buildings designed for rapid deployment, with 60-90% of construction completed off-site in controlled environments and buildings engineered to meet all federal, state, and local codes. Relocatable buildings can be transported and re-installed multiple times over their useful life, while permanent modular structures are virtually indistinguishable from traditional construction and can support multi-story configurations. The vertical integration across design, manufacturing, transportation, construction, and financing enables 50% faster time from design to occupancy compared to traditional construction.

Reliant's revenue model is asset-heavy and subscription-based, generating recurring lease income from modular building fleets deployed across multiple verticals. The company grew rapidly during the 2011-2014 oil and gas boom, achieving 55,000% revenue growth and ranking #3 on Inc. Magazine's 5000 list of fastest-growing private companies. It expanded into Canada and the Pacific Northwest and diversified into education, healthcare, and government verticals. In May 2026, Reliant was acquired by Sunbelt Rentals for $650 million and now operates as Aries Building Systems within Sunbelt's specialty rental portfolio.
