Mayville Engineering Company, Inc. (MEC) · Nov 3, 2026 · Earnings
Guidance cut — FY26 adjusted EBITDA midpoint cut to $50M from $56M; FCF midpoint to -$11M from $11M
Mayville Engineering’s earnings show accelerating data-center demand and a sales beat, but lower EBITDA and cash-flow guidance raise execution concerns.
MEC is shifting its growth engine toward Datacenter & Critical Power while expanding capacity to keep up with demand; after raising its 2026 sales outlook in August, the company is now using the quarter to show that demand is arriving but execution and cash conversion remain strained. The Thomson, Georgia facility and planned investment are intended to add roughly $50 million of annual capacity by 2028, with broader earnings contribution beginning in 2027.
The quarter beat the revenue bar but only met the earnings bar. Sales reached $170.4 million versus a published consensus of roughly $165.1 million, while adjusted diluted EPS of $0.15 was approximately in line with consensus. The operating improvement was real—Datacenter & Critical Power sales rose 64.9% year over year and adjusted EBITDA margin improved to 10.0%—but launch, outsourcing and premium-labor costs continued to absorb much of the benefit.
| Metric | Q3 2026 | Q3 2025 | Consensus / Prior guidance |
|---|---|---|---|
| Net sales (Results) | $170.4M (+18.1%) | $144.3M | ~$165.1M consensus |
| Adjusted diluted EPS (Adjusted Net Income) | $0.15 | $0.10 | ~$0.15 consensus |
| Adjusted EBITDA (Reconciliation) | $17.0M (+20.4%) | $14.1M | $17.0M Q3 midpoint guidance |
| Free cash flow (Reconciliation) | $(3.4)M | $(1.1)M | — |
| FY26 net sales guidance (Financial Guidance) | $630M–$640M | $546.5M actual | $620M–$650M prior |
| FY26 adjusted EBITDA guidance (Financial Guidance) | $48M–$52M | $47.1M actual | $52M–$60M prior |
| FY26 free cash flow guidance (Financial Guidance) | $(16)M–$(6)M | $26.9M actual | $7M–$15M prior |
The important change is the full-year reset, not the quarterly beat. MEC kept the sales midpoint at $635 million but narrowed the range, cut the adjusted EBITDA midpoint from $56 million to $50 million, and moved free-cash-flow guidance from positive $7 million–$15 million to negative $16 million–$6 million. That says demand is strong enough to support growth, but the cost of launching programs, expanding capacity and funding working capital is running materially heavier than the prior outlook. 〔0〕
The growth story is advancing, but profitability is lagging the ramp. MEC secured approximately $45 million of new Datacenter & Critical Power awards and said its qualified pipeline exceeds $200 million, while that end market generated $37.2 million of quarterly sales. Yet free cash flow was negative as capital spending and working capital absorbed cash, and net debt stood at $146.6 million with only $30.3 million of cash and revolver availability.
The capacity investment is strategically logical but increases near-term execution pressure. MEC closed the Thomson facility on October 1 and expects it, together with equipment investment, to add approximately $50 million of annual revenue capacity by 2028; that supports the company’s stated bottleneck, but the benefits are deferred while spending and launch costs arrive first.
Bottom line: MEC is proving the data-center demand thesis with a revenue beat and new awards, but the lower EBITDA and sharply negative cash-flow outlook mean the growth is arriving less profitably and more capital-intensively than previously expected.maq
