Negatives

• Gross margin decreased to 23.9% in Q3 2025 (from 28.9%) and 26.9% for the nine months ended September 30, 2025 (from 29.4%), primarily due to strong sales growth in comparatively lower-margin products and temporary inefficiencies related to accelerated production ramp-up.

• Selling, general and administrative (SG&A) expenses increased by 39% in Q3 2025 and 72% year-to-date, partly due to higher costs associated with employee incentive programs and customer relationship improvement efforts.

Risks

• The macro-economic environment, both in the U.S. and internationally, could impact business and expectations regarding industry growth.
• Uncertainties arising from global events (including the Russia-Ukraine and Israel-Hamas conflicts), natural disasters, or pandemics, and their impact on material prices.
• The ability to develop and successfully launch new products is crucial for sustained growth.
• Fluctuations in labor costs and other employment-related expenses could affect profitability.
• Loss of key suppliers and disruptions in the supply of raw materials pose operational risks.
• The company's ability to raise additional capital when needed and maintain sufficient liquidity is a concern.
• Uncertainties exist around the company's ability to meet funding conditions under its financing arrangements and access to capital.
• The impact of rising interest rates could increase borrowing costs.
• Changes in economic conditions, including inflationary trends in the price of raw materials, could affect costs and pricing.
• Reliance on information technology carries risks of potential security lapses and/or cyber-attacks.
• The ability to accurately forecast sales and the extent to which sales result in recorded revenues is critical.
• Changes in customer demand for products could impact sales volumes.
• Volatility in oil and gas prices affects a segment of the company's market.
• The impact of U.S. tariffs on imports and exports, including compliance disruptions such as the Uyghur Forced Labor Prevention Act (UFLPA), could delay goods from China.
• The potential impact of higher warranty costs and the company's ability to mitigate such costs remains a risk.
• Delays and challenges in recruiting and retaining key employees consistent with the company's plans could hinder operations.
• Damage to reputation or other adverse consequences could arise if employees, suppliers, or partners violate anti-bribery, competition, export/import, trade sanctions, data privacy, environmental, human rights, or other laws.
• The impact of unanticipated changes in the effective tax rate, the adoption of new tax legislation, or exposure to additional income tax liabilities could affect financial results.
• Weichai America Corp.'s beneficial ownership of approximately 46.5% of outstanding common stock and majority representation on the Board of Directors allows it to exercise control over matters requiring stockholders' approval, potentially delaying or preventing a change of control or changes in management without its support.

Future Outlook

The company expects continued positive trends in net sales growth and profitability, driven by its strategic prioritization of higher-growth, higher-margin markets like data centers and oil and gas. Management is actively pursuing initiatives to enhance and expand manufacturing capacity to meet increasing demand from data center markets. The company is committed to focusing on growth opportunities and investment while optimizing its cost structure to enhance growth and profitability and deliver sustained shareholder value.

Management Comments

• "PSIs growth in net revenue for the nine months in 2025 was driven by power systems markets, including data center and oil and gas products, partially offset by lower sales from more mature, lower-margin markets such as industrial."
• "This shift in markets reflects our conscious strategic prioritization toward higher growth, higher-margin markets with less emphasis on more mature markets."
• "We are 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, we are actively pursuing several initiatives to enhance and expand manufacturing capacity to meet the increasing demand from data center markets."
• "Pivoting the focus to these markets is driving current net sales growth and profitability. Through expanded capacity and strategic partnerships, we expect this positive trend to continue."
• "We are committed to efficiently managing expenses, including streamlining operating expenses and prioritizing certain R&D investments in support of long-term growth objectives."
• "We are committed to focusing on growth opportunities and investment while also optimizing our cost structure to enhance growth and profitability, ultimately delivering sustained value to our shareholders."

Industry Context

The company's strategic shift towards higher-growth, higher-margin markets, particularly data centers and oil and gas, aligns with broader industry trends. The data center market is experiencing rapid expansion, driving demand for power systems. While the oil and gas market has seen year-over-year growth from historic lows, the company acknowledges that sales levels may not reach previous highs due to lower rig counts, indicating a need for balanced investment and strategic positioning within this volatile sector. The company's focus on emission-certified engines and alternative fuels also positions it within the growing demand for cleaner energy solutions.

Stakeholder Impact

• **Shareholders:** Significant increases in net income and EPS, along with a stronger balance sheet and improved liquidity, are positive for shareholder value. Weichai's majority control limits the influence of other shareholders on certain corporate decisions.
• **Employees:** Higher costs associated with employee incentive programs indicate potential benefits for employees. The company's focus on growth and capacity expansion could lead to job creation or stability.

• **Suppliers:** Increased inventory purchases and expanded manufacturing capacity suggest higher demand for raw materials and components, benefiting suppliers. However, tariff costs and supply chain disruptions remain a risk.
• **Creditors:** Debt refinancing with an extended maturity date and increased borrowing capacity, coupled with improved profitability and cash flows, strengthens the company's creditworthiness. Full repayment of the Shareholders Loan Agreement also reduces certain debt obligations.

Key Dates

Recommendation

The company has demonstrated exceptional financial turnaround and growth, with net sales increasing by 60% and net income more than doubling year-to-date. The strategic pivot towards high-growth, high-margin markets like data centers is proving successful, and management is actively investing in capacity expansion to capitalize on this demand. The successful debt refinancing significantly improves the balance sheet and liquidity, removing a key concern. While gross margins saw a temporary dip due to product mix and ramp-up, the underlying growth and strategic direction are very compelling. The release of the deferred tax asset valuation allowance further bolsters the financial picture. These factors, combined with a clear growth strategy and improved financial health, suggest a strong positive outlook for investors.
