Current report
The Company has experienced tariff costs associated with its supply chain products. The Supreme Court's decision to strike down tariffs and the administration's response have created significant uncertainty regarding the scope, rate, duration, and legal authority for future tariffs. We are actively assessing the evolving tariff environment and are committed to proactively mitigating any associated risks through strategic sourcing, pricing actions, and supply chain agility.
Current report
The company remains confident in the Company’s long-term strategy and market positioning. Given broader market conditions, ongoing operational initiatives, and variability in customer order timing, the Company has determined it is appropriate to take a disciplined approach and not provide business outlook for 2026 at this time. Management will continue to evaluate its ability to provide outlook as execution progresses and visibility improves.

Current report
Net sales increased $246.4 million, or 52%, compared to 2024, as a result of sales increases of $260.6 million in the power systems end market, partly offset by decreases of $8.5 million and $5.7 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 material handling market.
Current report
Gross profit increased by $44.4 million, or 32%, to $184.9 million in 2025, compared to $140.5 million in 2024. Gross margin was 25.6% and 29.5% in 2025 and 2024, respe ctively. Thedecrease in gross margin is primarily due toinefficiencies related to our accelerated production ramp-up for data center product lines.
Current report
R&D expenses in 2025 and 2024 were $18.2 million and $20.1 million, respectively. The decrease of $1.9 million, or 9%, was primarily driven by the timing of R&D program expenditures and the recovery of R&D costs from certain customers.
Current report
Selling, general and administrative (“SG&A”) increased in 2025 by $18.4 million, or 49%, compared to 2024. The increase is primarily due to a $4.3 million favorable non-recurring legal reserve reduction in 2024, $4.4 million higher costs associated with employee incentive programs, $3.9 million expense related to customer relationship improvement efforts, and $5.8 million mainly from increased sales and administrative expenses to support ongoing business growth in 2025.

Previous report
The Company anticipates an increase in sales for 2025 compared to 2024, driven by expected growth in the power systemsend market including products supporting data centers, while sales in the industrial and transportation end markets are projected to remain about flat. Notwithstanding this outlook, which is being driven in part by expectations for stable supply chain dynamics and a continuation of favorable economic conditions within the United States and across the Company’s various markets, the Company cautions that significant uncertainty remains as a result of supply chain challenges, inflationary costs, commodity volatility, ongoing geopolitical and macroeconomic uncertainties, especially with the latest tariff announcements and the possible impact on trade between the USA and the rest of the world, among other factors.
Previous report
Hyster-Yale Supply Arrangement: In 2023, Hyster-Yale began using alternative suppliers for several high-volume engines that the Company provides, including the 2.0L and 2.4L engines, due in part to supply chain issues related to UFLPA enforcement. As a result, the Company experienced a decline in sales volumes to Hyster-Yale in 2024.

Previous report
Net sales increased $17.0 million, or 4%, compared to 2023, as a result of sales increases of $100.6 million in the power systems end market, partly offset by decreases of $37.1 million and $46.6 million within the industrial and transportation end markets, respectively. Higher power systems end market sales were primarily due to increased demand for products across various applications, with the largest increases attributable to products used within the packaging market such as enclosures serving the fast-growing data center market, and oil and gas products. The Company is strategically prioritizing the rapidly expanding data center sector, improving and increasing our manufacturing capacity and capabilities to meet our customers’ evolving demands for our products. Decreased industrial end market sales are primarily due to decreases in demand for products used within the material handling and arbor care markets, as well as the direct effects of enforcement of the UFLPA, which limited the Company’s ability to import certain raw materials. The decreased sales within the transportation end market were primarily attributable to lower sales in the truck and school bus market from ceasing sales of emission-certified engines into this market, and new compliance and regulatory requirements that changed engine product offerings in this market.
Previous report
Gross profit increased by $34.7 million, or 33%, to $140.5 million in 2024, compared to $105.9 million in 2023. Gross margin was 29.5% and 23.1% in 2024 and 2023, respe ctively. The increase in gross margin is primarily due to improved sales mix, pricing actions, higher operating efficiencies, and lower warranty costs primarily attributable to the Company’s sales shift away from certain transportation customers. For the year ended December 31, 2024, warranty costs were $6.5 million, a decrease of $6.5 million compared to warranty costs of $13.0 million in the same period last year, mainly attributable to changes in estimates for preexisting warranties. A majority of the warranty activity is attributable to products sold within the transportation end market in prior years.
Previous report
R&D expenses in 2024 and 2023 were $20.1 million and $19.5 million, respectively. The increase of $0.6 million, or 3%, was primarily related to the testing of new products.
Previous report
Selling, general and administrative (“SG&A”) decreased in 2024 by $3.0 million, or 7%, compared to 2023. The decrease is primarily due to a decrease in accrued legal settlements of $4.7 million, lower professional fees and the decrease in selling expenses associated with decreased sales in the transportation market.

Previous report
The Company’s ability to continue as a going concern is dependent on extending and amending, refinancing or repaying the indebtedness outstanding under the Company’s existing debt arrangements. Without additional financing, the Company anticipates that it will not have sufficient cash and cash equivalents to repay amounts owed under its existing debt arrangements as they become due, which raises substantial doubt about the Company’s ability to continue as a going concern within one year from the date of filing. In order to provide the Company with a more permanent source of liquidity, management plans to seek an extension and amendment and/or replacement of its existing debt agreements or seek additional liquidity from its current or other lenders before the maturity dates in 2025. There can be no assurance that the Company’s management will be able to successfully complete an extension and amendment of its existing debt agreements or obtain new financing on acceptable terms, when required or if at all.

PSI’s business is impacted by the current macroeconomic and geopolitical environment, which has contributed to differing levels of recovery in the global economy. For example, although the oil and gas market, in which the Company has historically operated, has experienced year over year growth from its historic lows, sales levels may not reach their previous higher levels because of rising crude oil prices and lower rig counts. The Company has been actively navigating these challenges by balancing its investments, expenses, pricing and sales efforts in this market as well as others.
