Mayville Engineering screens cheap on a growth-adjusted basis with a recent earnings beat streak, but heavy insider selling, weak momentum, and quality metrics well below the engine's floor keep the exit signal in place.

About Mayville Engineering Company, I
About Mayville Engineering Company, I
Mayville Engineering Company runs 27 U.S. manufacturing facilities across nine states, totaling approximately three and a half million square feet, serving OEM customers in heavy- and medium-duty commercial vehicles, construction and access equipment, powersports, data centers, and agriculture. The company's top customer, PACCAR, represented 13.6% of 2025 net sales, while its top ten customers combined accounted for 62.3%, and the company employs approximately 2,400 people.
Mayville earns revenue as a value-added contract manufacturer, taking OEM parts from design and prototyping through fabrication, aluminum extrusion, coating, and assembly, then passing through commodity-price swings via contractual mechanisms that the company says limits its exposure to tariffs and raw-material volatility. Its more than 40-year relationship with John Deere, which generated $54 million, or 10.0% of 2025 revenue across more than 65 platforms, illustrates how the company expands wallet share within existing accounts rather than relying on new-logo growth alone. Because most customer arrangements consist of open-ended requirement contracts rather than firm-volume commitments, Mayville depends on OEM production schedules and forecasts that customers can revise or cancel with limited notice. The company has also pursued acquisitions, including Accu-Fab, to build out capacity in the data center and critical power end market, an area of increasing capital allocation focus.
Show full overview
Mayville's growing bet on the data center and critical power end market via the Accu-Fab acquisition ties an increasing share of future results to hyperscaler capital-spending cycles, a historically more volatile demand source than the company's legacy commercial-vehicle and agriculture business. The 10-K also flags that OEM customers could choose to insource fabrication work currently outsourced to Mayville, or shift production quantities with little notice since most supply arrangements lack firm long-term volume commitments - a structural risk distinct from any single customer's share of sales.
