What ENC does

ENC (ElDorado National California) is a U.S. heavy-duty transit and paratransit bus manufacturer operating from a 227,000-square-foot ISO 9001-certified facility in Riverside, California. Founded in 1975 and acquired by Rivaz Inc. in late 2024, ENC produces the AXESS platform (33', 35', and 40' lengths) in clean diesel, CNG, diesel-electric hybrid, and zero-emissions variants — including the AXESS EVO-BE battery-electric bus with up to 738 kWh of energy storage and the upcoming AXESS EVO-FC hydrogen fuel cell bus with nearly 400 miles of range. The company also manufactures the mid-sized E-Z Rider II (30', 32', 35') and supports an aftermarket parts operation with direct fulfillment from Riverside.

ENC's core technology stack combines a hand-welded 304-grade stainless steel monocoque body structure, BAE Systems Gen3 electric drive, Proterra battery systems, and I/O Controls Multiplex Electrical architecture. All vehicles are Buy America compliant, FTA Altoona tested for 12 years/500,000 miles, and FMVSS/DOT/EPA/NHTSA/ADA certified. Customers include public transit agencies (SFMTA, Foothill Transit, SEPTA, York Region Transit), airports (DFW, LAX, Denver, Cleveland Hopkins), universities (Harvard, UCSD, Rutgers, Clemson, Georgia State), and private operators (Academy Bus, United Airlines).

The company sells primarily through a direct regional field sales force (West, Southwest, Northeast, Midwest) supported by cooperative purchasing agreements (NEORide covering 40+ agencies across 12 states; Washington State DES covering 30+ agencies including Sound Transit and King County Metro), with Canadian distribution handled through dealer City View Bus Sales. Pricing is quote-based and not publicly disclosed; ENC offers a standard 2-year/50,000-mile warranty plus pass-through component warranties. Revenue derives from one-time bus sales and recurring aftermarket parts and warranty services, with the company in active production following its June 2025 restart under Rivaz ownership.

Direct peers

• New Flyer of America (NFI Group): The largest heavy-duty transit bus manufacturer in North America, offering diesel, hybrid, battery-electric, and hydrogen fuel cell buses. Directly competes with ENC in US and Canadian transit agency procurements with overlapping propulsion platforms and customer base.
• Gillig: A leading US heavy-duty transit bus manufacturer based in California, offering diesel, CNG, hybrid, and battery-electric configurations. Direct competitor to ENC in the Buy America-compliant domestic transit bus segment.
• Nova Bus (Volvo Group): Volvo-owned North American transit bus manufacturer producing heavy-duty buses for US and Canadian agencies. Directly competes with ENC, with John Obert (now ENC's VP Transit Sales) previously holding leadership at Nova Bus.
• Motor Coach Industries (MCI): NFI Group subsidiary manufacturing intercity coaches and commuter buses. Comparable to ENC in heavy-duty bus manufacturing and serving overlapping agency/private operator customer segments in North America.
• BYD Motors: Chinese electric vehicle manufacturer with growing North American transit bus presence, including battery-electric models. Competes with ENC in the zero-emission transit bus segment despite the Buy America preference for domestic OEMs.
• Blue Bird Corporation: US-based bus manufacturer producing Type A, C, and D school buses as well as activity and shuttle buses. Comparable to ENC's E-Z Rider II mid-sized platform in the smaller bus and shuttle segments.

Emerging players
