First Quarter Net Sales of $128.6 million
First Quarter Net Income of $7.3 million
Diluted EPS of $0.32 for the Quarter

WOOD DALE, Ill., May 11, 2026 (GLOBE NEWSWIRE) -- Power Solutions International, Inc. (the “Company” or “PSI”) (Nasdaq: PSIX), a leader in the design, engineering and manufacture of emission-certified engines and power systems, today announced its financial results for the first quarter of 2026.

Financial Highlights

Dino Xykis, Chief Executive Officer, said: “Our first quarter results were below the strong prior-year period, which had benefited from significant growth in our Power Systems business. The year-over-year declines in sales and profitability primarily reflected softer oil and gas demand, the timing of certain Power Systems shipments, and elevated production costs associated with the capacity ramp-up in our Wisconsin operations.

At the same time, demand related to data center applications remains solid. Gross margin improved sequentially from the fourth quarter of 2025, partially offset by unfavorable product mix.”

First Quarter 2026 Results

Net sales for the first quarter of 2026 were $128.6 million, a decrease of $6.9 million, or 5%, compared to the first quarter of 2025. The decrease reflected lower sales in the power systems end market of $10.2 million, partially offset by increases of $3.0 million and $0.3 million in the industrial and transportation end markets, respectively. Sales in the power systems end market declined primarily due to softness in oil and gas markets, together with uneven order patterns and shipment timing for data center-related products. The Company continues to see strong demand for data center power solutions, and expects sales to increase in the second half of 2026. However, the timing and ultimate volume of related shipments remain subject to customer scheduling, manufacturing throughput, supply-chain factors, and other variables, and the Company is not predicting any specific level of data center revenue in any future period.

Gross profit for the first quarter of 2026 was $29.4 million, a decrease of $10.9 million, or 27%, compared to the first quarter of 2025. Gross margin in the first quarter of 2026 was 22.9%, compared to 29.7% in the same period last year. Gross margin reflected a lower mix of oil and gas products, together with elevated production costs associated with capacity ramp-up activities supporting data center-related applications at the Company’s Wisconsin operations. On a sequential basis, gross margin improved by approximately 100 basis points compared to the fourth quarter of 2025, owing in part to the Company’s efforts to improve operational efficiency in Wisconsin, but was partially offset by an unfavorable product mix in the first quarter. The Company’s capacity ramp-up activities at its Wisconsin operations are continuing, and the Company expects related production costs to persist; the trajectory of any further sequential improvement remains subject to product mix, throughput and other operational factors.

Research and development expenses during the three months ended March 31, 2026 and 2025 were $4.8 million and $4.2 million, respectively. The increase was primarily driven by higher R&D program expenditures to support new programs in 2026 and the recovery of R&D costs from certain customers in 2025.

Selling, general and administrative expenses were $13.0 million during the first quarter of 2026, an increase of $1.9 million, or 17%, compared to the same period in the prior year. The variance primarily reflects higher compensation expense related to the revaluation of previously awarded SARs, incremental selling and administrative expenses associated with MTL Manufacturing and Equipment, and other administrative and management expenses supporting the business in 2026.

Interest expense was $1.7 million in the first quarter of 2026, compared to $1.8 million in the same period in the prior year, primarily due to lower overall effective interest rates.

Income tax expense was $2.4 million in the first quarter of 2026, compared to $3.8 million in the same period of the prior year. The decrease was primarily driven by lower pre-tax income in 2026, partially offset by a higher effective tax rate.

Balance Sheet Update

The Company’s cash and cash equivalents were approximately $45.1 million, and total debt was approximately $103.4 million, as of March 31, 2026. This compares to cash and cash equivalents of approximately $41.3 million and total debt of approximately $96.8 million as of December 31, 2025. Total debt as of March 31, 2026 included borrowings of $95.0 million under the Company’s Revolving Credit Agreement.

Outlook for 2026

Given ongoing variability in order timing and market conditions, the Company is not providing formal full-year guidance at this time. Based on current visibility, the Company currently expects second-quarter 2026 revenue to be generally consistent with the first quarter on a sequential basis. The Company anticipates stronger sales growth in the second half of 2026, approximately in line with sales in the second half of 2025, as larger Power Systems orders move into production and are recognized as revenue. However, the timing and ultimate volume of those shipments remain subject to customer scheduling, manufacturing throughput, supply chain factors and other variables. There can be no assurance that those orders will translate to a uniformly stronger second half. Continued softness in the oil and gas end market is expected to weigh on quarterly revenue trends, and capacity ramp-up activities at the Company’s Wisconsin operations and their related cost effects on gross margin are expected to continue.

Non-GAAP Financial Measures

In addition to the results provided in accordance with U.S. GAAP above, this report also includes non-GAAP (adjusted) financial measures. Non-GAAP financial measures provide insight into selected financial information and should be evaluated in the context in which they are presented. These non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP, and non-GAAP financial measures as reported by the Company may not be comparable to similarly titled amounts reported by other companies. The non-GAAP financial measures should be considered in conjunction with the consolidated financial statements, including the related notes, and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this report. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated below.

The Company believes that Adjusted net income, Adjusted net income per share – diluted, EBITDA, and Adjusted EBITDA provide relevant and useful information, which is widely used by analysts, investors and competitors in its industry as well as by the Company’s management in assessing the performance of the Company. Adjusted net income is defined as net income as adjusted for certain items that the Company believes are not indicative of its ongoing operating performance. Adjusted net income per share – diluted is a measure of the Company’s diluted earnings per common share adjusted for the impact of special items. EBITDA provides the Company with an understanding of earnings before the impact of investing and financing charges and income taxes. Adjusted EBITDA further excludes the effects of other non-cash charges and certain other items that do not reflect the ordinary earnings of the Company’s operations.

Adjusted net income, Adjusted net income per share – diluted, EBITDA, and Adjusted EBITDA are used by management for various purposes, including as a measure of performance of the Company’s operations and as a basis for strategic planning and forecasting. Adjusted net income, Adjusted net income per share – diluted, and Adjusted EBITDA may be useful to an investor because these measures are widely used to evaluate companies’ operating performance without regard to items excluded from the calculation of such measures, which can vary substantially from company to company depending on the accounting methods, the book value of assets, the capital structure and the method by which the assets were acquired, among other factors. They are not, however, intended as alternative measures of operating results or cash flow from operations as determined in accordance with U.S. GAAP.

The following table presents a reconciliation from Net income to Adjusted net income for the three months ended March 31, 2026 and 2025:
