Company Overview

Solaris Energy Infrastructure, Inc. (“SEI”), formerly known as Solaris Oilfield Infrastructure, Inc., is a U.S.-based energy infrastructure and logistics company focused on providing equipment, power solutions, and operational services to the energy industry. The company historically built its business around mobile proppant management systems used in hydraulic fracturing operations and has expanded into distributed power generation and related energy infrastructure services. SEI operates primarily within the broader oilfield services, energy logistics, and distributed energy infrastructure sectors.

The company’s principal revenue drivers include equipment rentals, logistics systems, field services, and power infrastructure solutions supporting upstream oil and gas operations and industrial energy demand. SEI serves exploration and production companies, oilfield service providers, and industrial customers primarily in North America. Its strategic positioning has been tied to modular infrastructure systems designed to improve operational efficiency, reduce labor intensity, and support increasingly electrified field operations. The company evolved from a specialized last-mile proppant logistics provider into a broader infrastructure platform through organic expansion and investment in distributed power and energy solutions, as reflected in recent public filings and investor communications.
