(MEC) files its annual report describing a diversified, U.S.-based contract manufacturing business serving heavy- and medium-duty commercial vehicles, construction & access equipment, powersports, data center & critical power, agriculture and military markets through 27 facilities and roughly 2,400 employees.
The company emphasizes "MEC Business Excellence" to drive operational, commercial and capital discipline, including automation, reshoring-focused growth and expansion in data center & critical power. Customer concentration is significant: in 2025, the top customer accounted for 13.6% of net sales and the top ten for 62.3%, with John Deere alone at 10.0%.
Risk factors highlight exposure to macroeconomic and trade-policy uncertainty, inflation in wages and materials, supply-chain disruptions, labor availability, and dependence on a limited number of large OEMs and key suppliers. MEC also notes higher leverage following the Accu-Fab acquisition and an amended revolving credit facility, plus broad regulatory, environmental, cybersecurity and climate-related risks.
Mayville Engineering Company reported a weak fourth quarter of 2025, with net sales up 10.7% year over year but a net loss of $4.4 million, or ($0.22) per diluted share, driven by launch costs and softer legacy demand. Adjusted EBITDA was $6.3 million, or 4.7% of net sales, down from 7.6% a year earlier, while free cash flow was $10.2 million, roughly flat after adjusting for a prior-year legal settlement.
Data Center & Critical Power net sales jumped to $20.4 million in the quarter, helped by the Accu-Fab acquisition and 12.7% organic growth, while Commercial Vehicle and Military declined. For full-year 2025, net sales were $546.5 million and Adjusted EBITDA was $47.1 million.
For 2026, MEC guides net sales between $580 million and $620 million, Adjusted EBITDA of $50 million to $60 million, and free cash flow of $25 million to $35 million, assuming $40 million to $50 million of Accu-Fab cross-selling revenue and improving legacy end markets.
