## Customers

The company sells primarily to global OEMs and direct end users that need engines and power systems tailored to specific applications and emissions requirements. Its products are used across power generation, industrial equipment, and transportation end markets, where customers value engineering support, certification, and application fit.

- **Global OEMs** (primary) — Buy engines and integrated power systems to embed in their equipment and rely on PSI for engineering support and certification.
- **Direct end users** (primary) — Purchase power systems for specific operating applications where emissions compliance and performance matter.
- **Power systems end market** (primary) — Includes standby, prime power, microgrid, demand response, and combined heat and power users.
- **Industrial equipment customers** (secondary) — Buy engines for forklifts, pumps, irrigation, compressors, arbor care, and construction equipment.
- **Transportation customers** (secondary) — Use engines in light- and medium-duty vocational trucks, school buses, transit buses, and utility vehicles.

- Global OEMs that integrate PSI engines into finished equipment
- Direct end users needing application-specific power solutions
- Power generation customers for standby and prime power systems
- Industrial equipment makers in material handling and construction
- Transportation customers such as bus and vocational vehicle builders

## Geography

Power Solutions International is headquartered and primarily operates from the United States, with manufacturing, assembly, engineering, R&D, sales, and distribution facilities in suburban Chicago, Illinois and in Darien and Beloit, Wisconsin. The company also sells internationally and sources a significant portion of materials from outside the U.S., which makes its business sensitive to trade policy, logistics, and currency movements.

- **United States** (94%) — Q1 2025 revenue disclosure
- **North America (outside of United States)** (3%) — Q1 2025 revenue disclosure
- **Pacific Rim** (2%) — Q1 2025 revenue disclosure
- **Europe** (1%) — Q1 2025 revenue disclosure
- **Other** (0%) — Q1 2025 revenue disclosure

- Primary operating base in suburban Chicago, Illinois
- Additional facilities in Darien and Beloit, Wisconsin
- Most revenue is generated in the United States
- International sales include North America outside the U.S., Europe, and Asia-Pacific
- Global sourcing exposes the company to tariffs and supply-chain delays

## Strategy

The company is focused on expanding higher-growth power systems applications, especially where demand is tied to data centers, oil and gas, and other specialized power needs. It also emphasizes new product development, manufacturing capacity expansion, and international distribution partnerships to broaden its addressable market and strengthen its competitive position.

- **Expand power systems capacity** (short-term) — Capacity is needed to serve growing demand in data center and related markets.
- **Shift toward higher-return end markets** (medium-term) — Focusing on stronger-demand applications can improve mix and competitive positioning.
- **Broaden international reach** (medium-term) — Distribution partnerships extend the product line into new regions without building a full direct footprint.
- **Increase aftermarket and component sales** (medium-term) — Installed-base monetization can deepen customer relationships and improve recurring revenue opportunities.

- Prioritize higher-growth, higher-return power systems applications
- Expand manufacturing capacity for data center demand
- Develop new natural gas and diesel engine products
- Leverage the Weichai relationship for product and market reach
- Grow international distribution through partners such as Baudouin
- Increase aftermarket sales of value-added components

## Risks

The business is exposed to tariff changes, cross-border supply-chain disruption, and geopolitical volatility because it sources materials globally and sells into multiple regions. It also faces customer concentration, cyclical demand in oil and gas and industrial markets, and execution risk if it cannot scale capacity or adopt new technologies as quickly as competitors.

- **Tariffs and trade policy changes** [high] — The company sources internationally, including from China, and may not fully pass higher costs to customers.
- **Customer concentration** [high] — The largest customer represented 20% of consolidated net sales in 2025, so demand loss would be meaningful.
- **Cyclical end-market demand** [medium] — Oil and gas, industrial, and transportation demand can weaken with macro conditions and rig count changes.
- **Supply-chain disruption** [high] — A majority of supplier facilities are outside the U.S., increasing exposure to delays and interruptions.
- **Technology and competitive adoption** [medium] — Competitors or suppliers adopting AI and other manufacturing technologies faster could weaken PSI's position.

- Tariffs can raise input costs and disrupt sourcing
- Global supply chain creates logistics and currency exposure
- Customer concentration can amplify the loss of a major account
- Oil and gas demand is cyclical and tied to rig counts
- Goodwill and warranty estimates can affect reported results

## Accounting

Revenue is recognized mainly when control of products transfers to the customer, typically on shipment or delivery, but some contracts are recognized over time during construction. Goodwill, indefinite-lived intangibles, and warranty obligations require judgment, so changes in assumptions can affect earnings and balance sheet values.

- **Revenue recognition timing** — Can shift reported revenue between periods
- **Goodwill impairment** — Could create non-cash charges if fair value declines
- **Warranty reserves** — Affects gross margin and liabilities
- **Credit loss allowance** — Can increase bad debt expense and reduce earnings

- Point-in-time revenue recognition for most shipped products
- Over-time revenue for certain construction-type contracts
- Extended warranty revenue recognized over the warranty period
- Goodwill impairment testing uses qualitative and quantitative judgments
- Warranty reserves and credit loss allowances depend on estimates
