Revenue drivers

• Industrial end market — Second-largest end market, at $26.8M or 18% of Q2 2026 net sales; applications include arbor care, material handling and forklifts, agricultural and turf, construction, pumps and irrigation, compressors and utility vehicles.
• Transportation end market — Smallest end market, at $3.4M or 2% of Q2 2026 net sales; covers light- and medium-duty vocational trucks and school and transit buses.
• United States geographic concentration — The U.S. accounted for $143.0M, or 94%, of Q2 2026 net sales, with the remainder split across North America outside the U.S., Pacific Rim, Europe and others.

Recent performance

Second quarter 2026 net sales were $152.5 million, down 21% from $191.9 million a year earlier, with declines of $34.6 million in power systems, $3.0 million in industrial and $1.7 million in transportation. Gross profit fell 24% to $41.4 million and gross margin was 27.1% versus 28.2%, though margin improved about 420 basis points sequentially from the first quarter. Net income was $16.9 million and diluted EPS $0.73, versus net income of $51.2 million and EPS of $2.22 in the prior-year quarter. Sales rose 18.6% from the first quarter of 2026, and total debt was reduced by about $30.8 million during the quarter.

Strategy

Management says it is prioritizing products with strong demand and higher gross margins while strengthening the balance sheet. The company is expanding manufacturing capacity to serve data center power markets and expects that pivot to drive net sales growth and profitability. It is pursuing operational improvement efforts at its Wisconsin facility, where capacity ramp-up costs are being incurred. It is also managing operating expenses, streamlining costs and prioritizing certain R&D investments.

Risks

• Oil and gas softness — Management cites ongoing softness in the oil and gas market as a drag on Power Systems demand and product mix.
• Data center revenue timing — The company says the timing and ultimate volume of data center power revenue depend on customer scheduling, manufacturing throughput and supply chain factors, and it is not predicting a specific level.
• Wisconsin ramp-up costs — Elevated production costs tied to capacity ramp-up at the Wisconsin operations weighed on Q2 2026 gross margin and are expected to persist.
• Revolving credit demand right — Listed risk factors include potential acceleration of maturity at any time under the uncommitted revolving credit agreement if a lender exercises its demand right.

Outlook

Management expects second-half 2026 sales to exceed first-half 2026 sales as larger Power Systems orders move into production. It points to strong demand for data center power solutions, partially offset by continued oil and gas softness. The company cautions that shipment timing and quarterly results may vary, and it is not predicting any specific level of data center revenue in any future period.
