Rhea-AI Filing Summary

Power Solutions International, Inc. reported a weaker first quarter of 2026 compared with 2025. Net sales were $128.6 million, down 5% year over year, as lower power systems revenue, especially in oil and gas and uneven data center orders, outweighed growth in industrial and transportation markets.

Net income fell to $7.3 million from $19.1 million, with diluted EPS dropping to $0.32 from $0.83. Gross margin declined to 22.9% from 29.7% due to mix and elevated production costs from capacity ramp-up in Wisconsin, although margins improved sequentially from the fourth quarter of 2025.

Adjusted EBITDA decreased to $13.9 million from $26.1 million. Cash and cash equivalents rose to $45.1 million, and total debt increased to $103.4 million as of March 31, 2026. The company expects second-quarter 2026 revenue to be generally consistent with the first quarter and anticipates stronger sales in the second half, roughly in line with the second half of 2025, driven by larger Power Systems orders, while noting continued softness in oil and gas and ongoing ramp-up costs.

Positive

  • Liquidity and cash generation strengthened: Cash and cash equivalents increased to $45.1 million as of March 31, 2026 from $41.3 million at December 31, 2025, supported by net cash provided by operating activities of $19.1 million in the first quarter.
  • Sequential gross margin improvement: While year-over-year gross margin declined, management noted gross margin improved by approximately 100 basis points versus the fourth quarter of 2025, reflecting early benefits from efficiency efforts in Wisconsin.
  • Data center demand remains solid: The company continues to see strong demand for data center power solutions and anticipates stronger sales in the second half of 2026, approximately in line with the second half of 2025 as larger Power Systems orders move into production.

Negative

  • Significant profit decline: Net income fell 62% year over year to $7.3 million, with diluted EPS down from $0.83 to $0.32, reflecting weaker margins and higher operating expenses.
  • Margin compression from mix and ramp-up costs: Gross margin declined from 29.7% to 22.9%, driven by a lower mix of oil and gas products and elevated production costs associated with capacity ramp-up activities in Wisconsin.
  • Ongoing end-market and cost headwinds: Management expects continued softness in the oil and gas end market and persistent capacity ramp-up costs, with no formal full-year 2026 guidance provided and second-half strength subject to order timing and operational factors.

Insights

Q1 2026 shows sharp profit compression, with management leaning on second-half recovery.

Power Solutions International delivered Q1 2026 revenue of $128.6 million, down 5%, but profits fell more sharply. Net income dropped 62% to $7.3 million as gross margin compressed from 29.7% to 22.9%, reflecting a weaker power systems mix and higher Wisconsin ramp-up costs.

Operating expenses rose 15%, driven by higher selling, general and administrative costs and increased R&D to support new programs. As a result, operating income was nearly halved to $11.4 million. Adjusted EBITDA of $13.9 million was down 47%, indicating broad profitability pressure despite stable interest expense.

Management expects Q2 2026 revenue to be generally consistent with Q1 and anticipates stronger sales in the second half of 2026, approximately in line with the second half of 2025, as larger Power Systems orders convert. However, they highlight continued softness in oil and gas, dependency on customer schedules and manufacturing throughput, and ongoing Wisconsin ramp-up costs as key variables.

Gross margin financial
"Gross margin in the first quarter of 2026 was 22.9%, compared to 29.7% in the same period last year."
Gross margin is the difference between how much money a company makes from selling its products and how much it costs to produce them, expressed as a percentage of sales. It shows how efficiently a company is turning sales into profit before other expenses like marketing or salaries. Higher gross margin means the company keeps more money from each sale, which is a good sign of financial health.
Adjusted EBITDA financial
"Adjusted EBITDA * | | $ | 13,875 | | | $ | 26,069 | | | $ | (12,194) | | | (47) | %"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
Revolving Credit Agreement financial
"Total debt as of March 31, 2026 included borrowings of $95.0 million under the Company’s Revolving Credit Agreement."
A revolving credit agreement is a flexible loan arrangement where a borrower can borrow, repay, and borrow again up to a set limit, similar to a credit card. It matters because it gives businesses or individuals quick access to funds whenever needed, helping manage cash flow and cover expenses without applying for a new loan each time.
Non-GAAP financial measures financial
"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 are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
Stock-based compensation financial
"Amounts reflect non-cash stock-based compensation expense for the three months ended March 31, 2026 and 2025."
Stock-based compensation is when a company pays employees, directors or consultants with shares or the right to buy shares instead of or in addition to cash. It matters to investors because issuing stock or options spreads ownership thinner (like cutting a pie into more slices), which can reduce each existing share’s claim on profits and can also change reported earnings; investors watch it to assess true cost of running the business and how management is incentivized.
Capacity ramp-up activities financial
"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."
Net sales $128.6 million -5% year over year
Net income $7.3 million -62% year over year
Diluted EPS $0.32 down from $0.83 in Q1 2025
Gross margin 22.9% down from 29.7% in Q1 2025
Adjusted EBITDA $13.9 million down from $26.1 million in Q1 2025
Guidance

The company expects Q2 2026 revenue to be generally consistent with Q1 2026 and anticipates stronger sales in the second half of 2026, approximately in line with the second half of 2025, driven by larger Power Systems orders.

Power Solutions International Announces First Quarter 2026 Financial Results
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 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
($ in millions, except per share amounts)March 31, 2026March 31, 2025Change
Net Sales$128.6$135.4(5)%
Gross Profit$29.4$40.3(27)%
Net Income$7.3$19.1(62)%
Diluted Earnings per Share$0.32$0.83$(0.51)
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.

FAQ

How did Power Solutions International (PSIX) perform financially in Q1 2026?

Power Solutions International reported weaker results in Q1 2026 versus 2025. Net sales were $128.6 million, down 5%, while net income dropped 62% to $7.3 million. Diluted EPS declined from $0.83 to $0.32 as margins compressed and operating expenses increased.

What drove the revenue and margin changes for PSIX in the first quarter of 2026?

Lower power systems revenue and higher production costs drove the change. Sales fell mainly from softer oil and gas demand and uneven data center orders. Gross margin declined from 29.7% to 22.9% due to product mix and elevated Wisconsin capacity ramp-up costs.

What guidance or outlook did Power Solutions International (PSIX) provide for 2026?

The company is not issuing formal full-year 2026 guidance. Management expects second-quarter 2026 revenue to be generally consistent with the first quarter and anticipates stronger sales in the second half, approximately in line with the second half of 2025, depending on order timing and operations.

How did PSIX’s non-GAAP metrics like Adjusted EBITDA change in Q1 2026?

Non-GAAP profitability metrics declined significantly. Adjusted EBITDA fell to $13.9 million from $26.1 million, while adjusted net income decreased to $8.0 million from $19.2 million. These measures exclude stock-based compensation, severance and certain legal costs.

What is Power Solutions International’s (PSIX) liquidity and debt position as of March 31, 2026?

Liquidity improved modestly while debt increased. Cash and cash equivalents were $45.1 million and total debt was $103.4 million, including $95.0 million under the revolving credit agreement. Operating cash flow of $19.1 million supported the higher cash balance.

Which end markets are most affecting PSIX’s performance in 2026?

Power systems and oil and gas are key swing factors. Lower power systems sales, especially tied to oil and gas and uneven data center orders, hurt Q1 2026 results. Industrial and transportation end markets saw modest growth, partially offsetting the decline.
