Added

Tariffs and changes in trade policy could materially increase our costs, disrupt our supply chain, and adversely affect our competitive position and results of operations.

Added

Several of the Company’s products are sourced internationally, including from China. The U.S. government has imposed, and may continue to impose, tariffs on products imported from China and other countries. Since early 2025, President Donald Trump signed executive orders imposing various tariffs on certain imports from Mexico, Canada, and China, and stated his intent to impose tariffs on any country that imposes tariffs on U.S. products. Certain products that we buy from our suppliers are, and may in the future be, subject to these tariffs, which could increase our manufacturing costs.

Added

We may not be able to pass these increased costs on to our customers without adversely affecting demand for our products. The scope, duration, and impact of current and future tariffs remain highly uncertain. Further, the imposition of tariffs on imports from China and other countries have the potential to materially and adversely impact the Company’s sales, profitability and future product launches.

Added

Additionally, the tariffs imposed by the U.S. have resulted, and may in the future result, in retaliatory tariffs by other countries against U.S. exports. The Company also sells its products on a global basis; and, therefore, if such retaliatory tariffs are imposed on exports of the Company’s products, this could make our exported products less competitive than products of our competitors who are not subject to such retaliatory tariffs.

Added

The U.S. government has indicated its intent to adopt a new approach to trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. The Company is evaluating U.S. government policy, which is subject to change in the current negotiating environment, pricing, its supply chain and its operational strategies to mitigate the impact of these tariffs; however, there can be no assurances that any mitigation strategies employed will remain available under government policy or that the Company will be able to offset tariff-related costs or maintain competitive pricing of its products. Any material reduction in sales or increase in costs resulting from tariffs or trade restrictions could have a material adverse effect on our business, financial condition, and results of operations.

Added

On February 20, 2026, subsequent to year end, the U.S. Supreme Court struck down tariffs imposed under the International Emergency Economic Powers Act (“IEEPA”). The President immediately imposed replacement tariffs under Section 122 of the Trade Act of 1974, which are temporary (150-day maximum duration), and has indicated intent to impose tariffs under other authorities going forward. The Company may be entitled to refunds of IEEPA tariffs paid during 2025, but to the extent PSI passed tariff costs through to customers, the Company may be required to reimburse customers for such amounts, which could reduce or eliminate any net benefit from refunds. The tariff environment remains highly uncertain.

Added

Furthermore, escalating geopolitical tensions, including the ongoing conflict in Ukraine and instability in the Middle East, and developments in Venezuela could disrupt global supply chains, increase commodity prices, and create broader economic uncertainty that adversely affects our business.

Removed

Several of the Company’s products are sourced internationally, including from China, where the U.S. has imposed tariffs on specified products imported from China. These tariffs have an impact on the Company’s material costs and have the potential to have an even greater impact, depending on the outcome of future trade negotiations and policies. The Company is evaluating U.S. government policy, which is subject to change in the current negotiating environment, pricing, its supply chain and its operational strategies to mitigate the impact of these tariffs; however, there can be no assurances that any mitigation strategies employed will remain available under government policy or that the Company will be able to offset tariff-related costs or maintain competitive pricing of its products. Further, the imposition of tariffs on imports from China and other countries have the potential to materially and adversely impact the Company’s sales, profitability and future product launches. U.S. government has indicated its intent to adopt a new approach to trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. For example, in early 2025, President Donald Trump signed executive orders imposing various tariffs on certain imports from Mexico, Canada, and China, and stated his intent to impose tariffs on any country that imposes tariffs on U.S. products. Certain products that we buy from our suppliers are, and may in the future be, subject to these tariffs, which could increase our manufacturing costs. Additionally, the tariffs imposed by the U.S. have resulted, and may in the future result, in threatened and actual retaliatory tariffs by other countries against U.S. exports. The Company also sells its products on a global basis; and, therefore, if such retaliatory tariffs are imposed on exports of the Company’s products, this could make our exported products less competitive than products of our competitors who are not subject to such retaliatory tariffs. Any material reduction in sales may have a material adverse effect on the Company’s results of operations.

Added

Our liquidity could be adversely affected by volatility in demand, supply‑chain constraints, and significant capital investment requirements inherent in our engine manufacturing operations.

Added

Our business requires substantial liquidity to fund working capital, capital expenditures, research and development, inventory purchases, and long‑term strategic initiatives. We rely on cash generated from operations, supplemented by available credit facilities, to meet these needs. Our ability to maintain adequate liquidity depends on several factors outside our control. For example, fluctuations in customer demand—particularly in the heavy‑equipment, transportation, industrial, and power‑generation markets—can lead to uneven order patterns that impact cash inflows. A sudden or prolonged decline in sales volumes could reduce operating cash flows and negatively affect our liquidity position.

Added

Additionally, our manufacturing processes depend on the availability of raw materials and key components such as castings, electronics, and specialized metals. Supply‑chain disruptions, including shortages, delivery delays, or sudden cost increases, may require us to hold higher levels of inventory or pay premium prices to secure materials. These conditions could increase our working capital requirements, compress margins, and reduce available cash.

Added

We also operate in a capital‑intensive industry that requires ongoing investment in production equipment, testing facilities, tooling, and emissions‑compliance technology. If we are unable to generate sufficient cash from operations or secure financing on favorable terms, we may need to delay or scale back critical investments, which could impair our competitiveness and innovation pipeline.

Added

Our access to credit markets may be affected by factors such as rising interest rates, tightening lending standards, deterioration in our credit metrics, or adverse changes in macroeconomic conditions. If we are unable to refinance existing indebtedness or obtain additional funding when needed, we may face increased borrowing costs or constraints on our operational and strategic flexibility.

Added

If any of these risks materialize, our liquidity, financial condition, and ability to execute our business strategy could be materially and adversely affected.

Removed

The Company’s management has concluded as of the filing of this 2024 Annual Report that, due to uncertainty surrounding the Company’s ability to extend or refinance its current debt agreements, substantial doubt exists as to its ability to continue as a going concern. The Company’s plans to alleviate the substantial doubt about its ability to continue as a going concern may not be successful, and it may be forced to limit its business activities or be unable to continue as a going concern, which would have a material adverse effect on its results of operations and financial condition.

Removed

The consolidated financial statements included herein have been prepared assuming the Company will continue as a going concern. In August 2024, the Company refinanced its debt through a new Uncommitted Revolving Credit Agreement (the “Revolving Credit Agreement”), with Standard Chartered Bank (“Standard Chartered”) and two other lenders. Additionally, also in August 2024, the Company entered into a new Shareholder’s Loan Agreement (the “SLA”) with Weichai. The new Revolving Credit Agreement and the new SLA will mature on August 30, 2025 and August 31, 2025, respectively, and have borrowing capacity of $120.0 million and $105.0 million, respectively. As of December 31, 2024, the Company had $120.0 million of total borrowings outstanding under its debt agreements.

Removed

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. 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. These consolidated financial statements do not include any adjustments that might result from the outcome of the Company’s efforts to address these issues.

Removed

Furthermore, if the Company cannot raise capital on acceptable terms, it may not, among other things, be able to do the following:

Removed

•continue to expand the Company’s research and product investments and sales and marketing organization;

Removed

•expand operations both organically and through acquisitions; and

Removed

•respond to competitive pressures or unanticipated working capital requirements.

Removed

The Company’s management has concluded that, due to uncertainties surrounding the Company’s future ability to refinance, extend and amend, or repay its outstanding indebtedness under its existing debt arrangements and other requirements under the Revolving Credit Agreement and other outstanding debt, in the future, substantial doubt exists as to its ability to continue as a going concern within one year after the date that these financial statements are issued. The Company’s plans to alleviate the substantial doubt about its ability to continue as a going concern may not be successful, and it may be forced to limit its business activities or be unable to continue as a going concern, which would have a material adverse effect on its results of operations and financial condition.

Removed

The consolidated financial statements included herein have been prepared assuming that the Company will continue as a going concern and contemplating the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company’s ability to continue as a going concern is dependent on generating profitable operating results, having sufficient liquidity, maintaining compliance with the covenants and other requirements under the new Revolving Credit Agreement and the new SLA, in the future, and extending and amending, refinancing or repaying the indebtedness outstanding under the Company’s existing debt arrangements.

Reworded

The Company has a significant amount of indebtedness and is highly leveraged. ItsCompany’s existing debt or any potential new debt could adversely affect its business and growth prospects.

Reworded

As of December 31, 2024,2025, the Company’s total debt obligations, including indebtedness under the Revolving Credit Agreement andwere SLA was $120.2$96.6 million. The Company’s debt arrangements contain and may contain in the future certain requirements, including specific financial and other covenants or restrictions. The failure or the inability to meet such obligations under existing debt or any new debt could materially and adversely affect the Company’s business and financial condition. In addition, the Company’s debt obligations could make it more vulnerable to adverse economic and industry conditions and could limit its flexibility in planning for or reacting to changes in its business and the industries in which it operates. The Company’s indebtedness and the cash flow needed to satisfy its debt obligations and the covenants contained in current and potential future debt agreements could have important consequences, including the following:

Added

The Company’s new Revolving Credit Agreement places limitations on its ability to make acquisitions and restricts its ability to incur additional indebtedness.

Removed

The Company’s new Revolving Credit Agreement places limitations on its ability to make acquisitions and restricts its ability to incur additional indebtedness, while the SLA places limitations or restrictions on the Company’s usage of borrowed funds. Any future failure by the Company to comply with the financial covenants set forth under the Company’s debt agreements, if not cured or waived, could result in the acceleration of debt maturities or prevent the Company from accessing availability of funds under the SLA. If the maturity of the indebtedness is accelerated, the Company may not have sufficient cash resources, or have the ability to obtain financing through alternative resources, to satisfy its debt and other obligations, and the Company may not be able to continue as a going concern.

Reworded

The continued market acceptance and growth of the market for efficient alternative-fueled, spark-ignited power systems, including natural gas, propane and gasoline, is a key tenet of the Company’s growth strategy. The impact of diesel emission regulations is expected to increase the cost and complexity of diesel power systems, but this may not materialize to the expected extent or at all. Also, customers, or potential customers, may not substitute natural gas, propane and gasoline-powered power systems for diesel power systems in response to these regulations. In addition, to the extent that diesel power system manufacturers develop the ability to design and produce emission-compliant diesel power systems that are more competitive than the Company’s alternative-fueled power systems, customers and potential customers may be less likely to substitute alternative-fueled power systems for diesel power systems. Furthermore, if alternative-fueled power systems are substituted for diesel power systems, there can be no assurance that the Company’s power systems would capture any portion of the potential market increase. If the industrial OEM market generally, or more specifically any of the OEM categories that represent a significant portion of the Company’s business or in which it anticipates significant growth opportunities for its power systems, fails to develop or develops more slowly than the Company anticipates, its business could be materially adversely affected. Lastly, the Company also faces competition from other forms of power systems, including electrification and fuel cells, which could limit its ability to grow in the future.

Removed

Lastly, the Company also faces competition from other forms of power systems, including electrification and fuel cells, which could limit its ability to grow in the future.

Reworded

Ownership of the Company’s stock is concentrated with Weichai and the founder of the Company, and therefore other stockholders’ ability to influence corporate matters is limited.

Reworded

As of MarchFebruary 1726, 2025,2026, Weichai beneficially owned 51.1%46.0% of the Company’s outstanding shares of Common Stock. Additionally, Gary S. Winemaster, the Company’s founder, former Chairman of the Board of Directors (the “Board”), former Chief Executive Officer, President and nonexecutive Chief Strategy Officer, beneficially owned approximately 14.4% of the Company’s outstanding shares of Common Stock. Each of these stockholders, by virtue of theirWeichai’s significant equity ownership in the Company, may be able to significantly influence, and, in the case of Weichai,and control the outcome of all matters requiring stockholder approval, including the election and removal of directors and any merger or other significant corporate transactions. The interests of these stockholders may not coincide with the interests of other stockholders. The concentration of ownership might also have the effect of delaying or preventing a change of control of the Company that other stockholders may view as beneficial. Weichai alone owns a majority of the outstanding shares of Common Stock and, therefore, it possesses voting control over the Company sufficient to prevent any change of control from occurring.

Added

Our relationship with Weichai, a Chinese state-owned entity, and heightened U.S.-China geopolitical tensions could subject us to increased regulatory scrutiny, reputational harm, and operational restrictions.

Added

The relationship between the United States and China has become increasingly strained in recent years, with ongoing tensions related to trade, technology, national security, and other matters. The U.S. government has taken, and may continue to take, actions that could affect companies with significant Chinese ownership or business relationships, including:

Added

•Enhanced scrutiny by the Committee on Foreign Investment in the United States (CFIUS) of transactions involving Chinese-affiliated entities;

Added

•Export control restrictions that could limit our ability to share technology or conduct business with Weichai or other Chinese entities;

Added

•Sanctions or other restrictions targeting Chinese state-owned enterprises or their affiliates;

Added

•Legislative or regulatory actions that could restrict or prohibit business relationships with Chinese state-owned entities; and

Added

•Increased disclosure requirements or other regulatory burdens applicable to companies with significant foreign government ownership.

Added

Any such actions could disrupt our strategic collaboration with Weichai, limit our access to certain markets or technologies, increase our compliance costs, or subject us to reputational harm. Additionally, negative public perception of companies with Chinese state ownership could adversely affect our relationships with customers, suppliers, and other business partners, particularly those in the defense, government contracting, or critical infrastructure sectors.

Added

We cannot predict the nature, timing, or impact of future geopolitical developments or government actions. Any material adverse developments in U.S.-China relations or actions targeting companies with Chinese state ownership could have a material adverse effect on our business, financial condition, results of operations, and stock price.

Reworded

In March 2017, Weichai entered into an Investor Rights Agreement (the “Rights Agreement”) with the Company upon execution of the SPA.Company. The Rights Agreement provides Weichai with majority representation on the Company’s Board and management representation rights. Weichai currently has four representatives on the Board which constitutes the majority of the directors serving on the Board. According to the Rights Agreement, during any period when the Company is a “controlled company” within the meaning of the Nasdaq Listing Rules, it will take such measures as to avail itself of the “controlled company” exemptions available under Rule 5615 of the Nasdaq Listing Rules of Rules 5605(b), (d) and (e). With Weichai being the majority owner of the Company’s outstanding shares of its Common Stock, Weichai is able to exercise control over matters requiring stockholders’ approval, including, among other matters, the election of the Directors, amendment of the Company’s Certificate of Incorporation and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of the Company or changes in management and will make the approval of certain transactions impractical without the support of Weichai.

Added

Artificial Intelligence Risk Factors

Added

The increasing use of artificial intelligence technologies by our competitors, customers, and suppliers could impact our competitive position.

Added

Artificial intelligence (“AI”) and machine learning technologies are rapidly evolving and are increasingly being adopted across industries, including in manufacturing. Our competitors, customers, and suppliers may adopt AI technologies that could affect our competitive position. If we fail to effectively adopt and integrate AI technologies, or if our competitors do so more successfully, we could experience a decline in our competitive position.

Added

We may also face risks from AI technologies used by third parties, including vendors, customers, and service providers, over which we have limited control. Any material disruption to our supply chain or competitive disadvantage resulting from third-party AI adoption could adversely affect our business, financial condition, and results of operations.

Removed

The Company’s inability to generate sufficient taxable income in the future may limit the Company’s ability to use net operating loss (“NOL”) carryforwards to reduce future tax payments.

Removed

The Company has NOL carryforwards with which to offset its future taxable income for U.S. federal income tax reporting purposes. If the Company should fail to generate a sufficient level of taxable income prior to the expiration of the NOL carryforward periods, then it will lose the ability to apply the NOLs as offsets to future taxable income. Similar limitations also apply to certain U.S. federal tax credits.

The Company and Weichai executed the Collaboration Agreement in order to achieve their respective objectives, enhance the cooperation alliance and share experiences, expertise and resources. Among other things, the Collaboration Arrangement established a joint steering committee, permitted Weichai to employ a limited number of technical, marketing, sales, procurement and finance personnel to work at the Company and established several collaborations related to stationary natural-gas applications and Weichai diesel engines. The Collaboration Agreement also provides for the steering committee to create various subcommittees with operating roles and otherwise governs the treatment of intellectual property of the parties prior to the collaboration and the intellectual property developed during the collaboration. On March 22, 2023, the Collaboration Agreement was extended for an additional term of three years.years, expiring in March 2026. The Company received a renewal notice from Weichai and is in the process of negotiating the renewal of the Collaboration Agreement; however, no formal extension has been executed as of the date of this filing. The Company’s sales to Weichai were $1.8$1.3 million and $1.7$1.8 million during 20242025 and 2023,2024, respectively. The Company purchased $21.5$39.8 million and $6.2$21.5 million of inventory from Weichai during 20242025 and 2023,2024, respectively.

Added

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.

Added

The potential for continued economic uncertainty and unfavorable oil and gas market dynamics may have a material adverse impact on the levels of future customer orders and the Company’s future business operations, financial condition and liquidity. On July 30, 2025, the Company amended its Revolving Credit Agreement with Standard Chartered Bank and three other lenders. The amended Revolving Credit Agreement allows the Company to borrow up to $135.0 million and extends the maturity date to July 30, 2027.

Removed

The Company continues to experience inflationary cost pressures for certain raw materials and other goods, which the Company continues to try to mitigate through price increases and other cost reduction measures. Additionally, the Company continues to experience ongoing tariff costs for its supply chain products and is trying to mitigate these impacts through price increases and other measures, such as seeking certain tariff exclusions, where available. The potential for continued economic uncertainty and unfavorable oil and gas market dynamics may have a material adverse impact on the levels of future customer orders and the Company’s future business operations, financial condition and liquidity.

Added

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.

Removed

The Company anticipates an increase in sales 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 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.

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.

Reworded

Sales declined in the firstsecond quarter of 2026, primarily within the power systems end market, reflecting uneven customer ordering patterns and some softness in the oil and gas market. Looking ahead, we expect sales to improve in the second half of the year, driven by demand in data center-related markets, partially offset by ongoing softness in the oil and gas market.

Reworded

The Company is focused on leading the business through a growth phase with a stronger balance sheet while strategically prioritizing products that demonstrate strong demand and higher gross margins. Consistent with those goals, the Company is actively pursuing several initiatives to enhance and expand manufacturing capacity to meet the increasing demand from data center markets. PivotingThe Company expects that pivoting the focus to these markets will drive net sales growth and profitability. Through expanded capacity and strategic partnerships, management expects this positive trend to continue.

Reworded

Given ongoing variability in order timing and market conditions, the Company is not providing formal full-year guidance at this time. Based on the current visibility,production schedule and information available as of the date of this release, the Company currently expects second-quartersecond-half 2026 revenuesales to exceed first-half 2026 sales and 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.

Cash Flows for the ThreeSix Months Ended MarchJune 31,30, 2026

Reworded

Net cash provided by operating activities was $19.1$75.7 million for the threesix months ended MarchJune 31,30, 2026, compared to $8.8$25.5 million for the threesix months ended MarchJune 31,30, 2025, representing an increase of $10.3$50.3 million in cash provided by operating activities year-over-year. The increase occurred despite a decrease in net income of $11.8$46.1 million, driven primarily by favorable changes in working capital. These changes included a significant source of cash from accounts receivable, reflecting improved collections in the current period, as well as a lower use of cash for inventory purchases compared to the prior‑year period. These favorable impacts were partially offset by increased uses of cash related to accrued expenses and accounts payable during the threesix months ended MarchJune 31,30, 2026 compared to MarchJune 31,30, 2025.
