MANAGEMENT COMMENTARY

“Our second quarter results reflect stronger-than-expected order activity within our Commercial Vehicle end market and continued momentum across our Datacenter & Critical Power end market," said Jag Reddy, President and Chief Executive Officer. "Our execution remained strong as we continued to invest in resources and equipment necessary to support the accelerating customer demand. As volumes increased, margins improved through better capacity utilization, though we continued to absorb project launch costs associated with the ramp up of new Datacenter & Critical Power programs. At the same time, we are making selective decisions to prioritize capacity for higher-value, higher-margin programs that support long-term profitable growth."

"During the quarter, we secured approximately $40 million of new Datacenter & Critical Power project awards as customer demand remained robust," Reddy continued. "Our qualified opportunity pipeline continues to exceed $125 million, supported by strong customer quoting activity. Within our Commercial Vehicle end market, demand trends improved during the quarter, and we expect continued recovery through the remainder of the year, complemented by steady activity in our Construction & Access end market. Reflecting these favorable trends, we are raising our full-year 2026 net sales guidance by approximately 5%."

"We also completed a common stock offering during the quarter, generating approximately $94 million in net proceeds," Reddy concluded. "The proceeds were immediately used to reduce debt and strengthen our balance sheet, increasing our available liquidity to more than $100 million. Given the significant opportunities we continue to see across the Datacenter & Critical Power infrastructure market, we also intend to use a portion of the net proceeds from the offering to invest an incremental $50 million in organic growth initiatives across 2026

​

and 2027 to expand capacity to support higher-value programs. These investments position MEC to deliver attractive, sustainable returns on invested capital as we capitalize on a multi-year secular growth opportunity."

PERFORMANCE SUMMARY

Net sales increased by 23.2% on a year-over-year basis in the second quarter of 2026, primarily due to organic growth in the Datacenter & Critical Power, Commercial Vehicle, and Construction & Access end markets and the impact of the Accu-Fab acquisition completed in the third quarter of 2025. These increases were partially offset by lower demand in the Powersports, Agriculture and Military end markets.

Manufacturing margin was $17.7 million in the second quarter of 2026, or 10.9% of net sales, versus $13.6 million, or 10.3% of net sales, in the prior year period. The year-over-year increase in manufacturing margin was primarily attributable to higher margin sales contribution from the Accu-Fab acquisition and improved capacity utilization as demand in several legacy end markets improved. This increase was partially offset by $2.1 million of project launch costs and higher costs associated with ongoing workforce expansion to support demand.

Bonuses and deferred compensation expense was $4.8 million in the second quarter of 2026 as compared to $1.5 million in the prior year period. Other selling, general and administrative expenses were $9.3 million in the second quarter of 2026 as compared to $10.3 million for the same prior year period. The decrease in other selling, general and administrative expenses primarily reflects non-recurring executive transition expenses and Accu-Fab acquisition-related costs in the prior year period, partially offset by incremental SG&A expenses associated with the acquisition.

Interest expense was $3.5 million in the second quarter of 2026, as compared to $1.4 million in the prior year period, due to increased average borrowings and interest rate under the Company’s revolving credit facility and the timing of debt
