Mayville Engineering Company, Inc. (MEC)

Over the past six months, MEC's stock price has seen significant movement, with the share price at $18.17 as of April 6, 2026, a 47.13% increase from the previous year. The stock has traded between $11.72 and $22.37 over the past 52 weeks. Recent earnings announcements have impacted the stock, with third-quarter 2025 net sales of $144.3 million, a 6.6% year-over-year increase driven by the Accu-Fab acquisition, though organic net sales declined by 9.1%. Following the fourth-quarter earnings release, the stock drifted 9.5% lower. MEC's 2026 guidance is robust, with expected revenue of $580–$620 million and EBITDA of $50–$60 million, driven by strength in the data center and critical power market.

MEC experiences some demand seasonality, with the fourth quarter typically being a softer period for its legacy end markets. In 2025, the company faced challenging customer demand across most of its traditional end markets, particularly in Commercial Vehicle, Powersports, and Agriculture, with customers scaling back production capacity. Elevated inventory levels in the commercial vehicle market, coupled with uncertainty surrounding 2027 EPA regulations, also contributed to a weaker outlook. However, demand in the data center and critical power market has shown robust and sustained momentum and is expected to remain a consistent growth opportunity for MEC.
