Mayville Engineering Company

What Mayville Engineering Company does

Mayville Engineering Company, Inc. (NYSE: MEC) is a U.S.-based value-added manufacturing partner founded in 1945 and headquartered in Milwaukee, Wisconsin. The company operates 27 manufacturing facilities across nine states with over 3 million square feet of production space and 2,500+ employees, providing vertically integrated services spanning design, prototyping and tooling, metal stamping, laser cutting, welding (including robotic integration), CNC machining, tube laser and bending, roll forming, aluminum extrusion, coating and finishing (including military-grade CARC), electromechanical assembly, and aftermarket components. MEC holds ISO 9001:2015, ISO 14001:2015, IATF 16949:2016, and ITAR certifications, and has been named the nation's #1 fabricator by The Fabricator Magazine for 16 consecutive years.

MEC serves OEM manufacturers across six primary end markets: heavy- and medium-duty commercial vehicles (including PACCAR), construction and access equipment, powersports, agriculture, military, and datacenter/critical power. The company drives operational improvement through its proprietary MEC Business Excellence (MBX) framework, which standardizes lean practices, Kaizen events, and asset optimization across facilities. Strategic acquisitions have expanded capability and reach: Mid-States Aluminum Corp. (closed July 2023, ~$96M) added aluminum extrusion, and Accu-Fab, LLC (closed July 2025) added a foothold in the datacenter/critical power market that drove a 470% segment revenue surge in Q1 2026.

MEC generates revenue through project-based work and multi-year contracts with OEM customers under a quote-based pricing model, supplemented by an aftermarket components business that produces recurring revenue. The company became publicly traded on the NYSE in 2019, has been 100% employee-owned via ESOP since 1985, and raised $100M in a May 2026 underwritten equity offering led by William Blair and Craig-Hallum to fund growth-sector capex and reduce revolver borrowings. FY2025 net sales were $546.5M and FY2026 guidance is $590-620M. A consumer products sub-brand, MEC Outdoors, manufactures shotshell reloaders since 1955.
