WOOD DALE, Ill., Nov. 06, 2025 (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, announced its record financial results for the third quarter 2025.

Financial Highlights

($ in millions, except per share amounts)	Quarter Ended
	September 30, 2025	September 30, 2024	Change
Net Sales	$203.8	$125.8	62%

Third Quarter 2025 Results

PSI reported record net sales of $203.8 million and net income of $27.6 million, or $1.20 per diluted share, for the three months ended September 30, 2025. This compares to net sales of $125.8 million and net income of $17.3 million, or $0.75 per diluted share, for the same period in 2024, representing increases of 62% in net sales and 59% in net income.

Dino Xykis, Chief Executive Officer, said, "We achieved the highest sales in our company's history this quarter, delivering strong financial performance with sales increasing 62% and net income rising 59%. These results underscore the robust demand for our power systems solutions, particularly within the data center market. During the quarter, we expanded our manufacturing capacity and increased production across key data center product lines. We are continuing to ramp up production to ensure on-time delivery while implementing targeted operational improvements to enhance efficiency, execution and future growth going forward."

Sales for the third quarter of 2025 were $203.8 million, an increase of $78.0 million, or 62%, compared to the third quarter of 2024, primarily as a result of a sales increase of $85.3 million in the power systems end market, offset by a decrease of $4.7 million and $2.6 million within the industrial and transportation end markets, respectively. This shift in market mix reflects our deliberate strategic focus on higher-growth sectors such as data centers and oil and gas. In particular, we are prioritizing the rapidly expanding data center sector by enhancing our manufacturing capacity and capabilities to meet evolving customer demand. The decline in industrial sales is largely attributable to softer demand in the materials handling market.

Gross profit increased by $12.3 million, or 34%, during the third quarter of 2025 as compared to the same period in the prior year. Gross margin in the third quarter of 2025 was 23.9%, a decrease of 5.0% compared to 28.9% in the same period last year. Gross margin was impacted due to strong sales growth in comparatively lower-margin products and temporary inefficiencies related to our accelerated production ramp-up.

Selling, general and administrative expenses were $15.3 million during the third quarter of 2025 and increased by $4.3 million, or 39%, compared to the same period in the prior year. The variance reflects higher costs associated with employee incentive programs, expense related to customer relationship improvement efforts, and increased sales and administrative expenses to support ongoing business growth in 2025.

Interest expense was $1.6 million in the third quarter of 2025 as compared to $2.8 million in the same period in the prior year, largely due to reduced outstanding debt and lower overall effective interest rates.

Income tax was a benefit of $0.9 million in the third quarter of 2025, compared to an expense of $0.3 million in the same period of the prior year. The tax benefit in the third quarter of 2025 was primarily driven by the release of a $7.0 million valuation allowance on deferred tax assets. The effective tax rate in the third quarter of 2024 was low mainly due to the utilization of net operating loss carryforwards and other tax credits.

Net income and diluted earnings per share were $27.6 million and $1.20, respectively, in the third quarter of 2025, compared to $17.3 million and $0.75, respectively, for the third quarter of 2024.

Balance Sheet Update

The Company's cash and cash equivalents were approximately $49.0 million, while total debt was approximately $96.7 million at September 30, 2025. This compares to cash and cash equivalents of approximately $55.3 million and total debt of approximately $120.2 million at December 31, 2024. Included in the Company's total debt at September 30, 2025 were borrowings of $95.0 million under the Revolving Credit Agreement.

Outlook for 2025

The Company anticipates strong sales growth of 45% for 2025 compared to 2024, driven by expected growth in the power systems end market including products supporting data centers, while sales in the industrial and transportation end markets are projected to remain flat.

Non-GAAP Financial Measures

In addition to the results provided in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") above, this press release 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 within the Company's Form 10-Q for the quarter ended September 30, 2025. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated below.

Non-GAAP Financial Measure	Comparable GAAP Financial Measure
Adjusted net income	Net income
Adjusted net income per share – diluted	Net income per share – diluted
EBITDA	Net income
Adjusted EBITDA	Net income

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.
