Power Solutions International Inc's Business Segments

We are a global producer and distributor of a broad range of high performance, certified low-emission, power systems that primarily run on non-diesel fuels such as natural gas, propane and gasoline, which are designed to meet emission standards of the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). Our customers include large, multinational original equipment manufacturers (OEMs) of off-highway industrial equipment and on-road medium trucks and busses, and we are a sole source provider of alternative fuel power systems for many of these customers. Our industrial power systems are currently used by OEMs in a wide range of industries with a diversified set of applications, including, stationary electricity generators, oil and gas equipment, forklifts, aerial work platforms, industrial sweepers, arbor equipment, agricultural and turf equipment, aircraft ground support equipment, construction and irrigation equipment, and other industrial equipment.

Power Systems for Off-Highway Industrial Equipment
Our power systems are customized to meet specific industrial OEM application requirements. Power system configurations range from a basic engine block integrated with appropriate fuel system components to completely packaged power systems that include any combination of cooling systems, electronic systems, air intake systems, fuel systems, housings, power takeoff systems, exhaust systems, hydraulic systems, enclosures, brackets, hoses, tubes and other assembled componentry.
Our power systems include (1) EPA and CARB emission-certified spark-ignited water-cooled internal combustion engines ranging from 0.97 liters to 22 liters, which use alternative fuels and gasoline, (2) non-certified spark-ignited water-cooled internal combustion engines ranging up to 22 liters, which similarly use alternative fuels and gasoline, and (3) emission-certified Perkins engines ranging from 0.5 liters to 7.1 liters, which use diesel fuel. Our diesel and alternative fuel power systems use water-cooled (as opposed to air-cooled), multi-cylinder engines.

Our products are sold into a diversified set of markets within the industrial OEM industry, including power generation, oil and gas, material handling, aerial work platforms, sweepers, arbor products, welding, airport ground support, agricultural, turf, construction and irrigation. Different types of power systems are used within different industry categories (from which we receive varying, unequal amounts of revenues).

Power Generation
We offer EPA and CARB emission-certified power systems, including 0.97 liter to 22 liter power systems that use alternative fuels, for stationary emergency and non-emergency power generation products. Emergency engines are stationary engines which operate solely in emergency situations and during required periodic testing and maintenance. Examples include engines used in generators to produce power for critical networks when electrical power from the local utility provider is interrupted, and stand-by engines that pump water in the event of a fire or flood. Non-emergency products include prime power generation products, which produce continuous generation of power for an extended period of time, and peak shaving products, which generate power at times of maximum power demand.
We currently supply our power systems to a substantial number of manufacturers of power generation products. We believe that our customers choose our power systems because of our broad range of emission-certified, spark-ignited power systems for this industry category. Additionally, by using a common fuel system and electronic controls across our range of power systems, we provide our customers with the opportunity to support and train their personnel on one standardized fuel system and one set of electronic controls employed throughout the range of products they acquire from us.

Oil and Gas
The oil and gas market category includes oil field pumps/components, compressors, on-site power generation and other machines and equipment used in the production of oil and gas. Previously, OEMs competing in these markets were generally not concerned about fuel economy, cost of repair or efficiency of operation. Today, however, there is a growing focus in this market category on, and understanding of, the costs associated with down time, the value of fuel savings with more economical solutions and the benefits of using product portfolios with consistent fuel systems and aftermarket support. We provide a power generation system to completed wells that is significantly more cost competitive when compared to the cost of using diesel fuel or utility grid power. Our power systems are capable of burning free well-head gas, thereby providing a distinct opportunity for oil producers to save on their operating expenses which becomes more important as the cost per barrel of oil decreases, as has happened during 2015. When the price of oil declines, oil becomes a more favorable source of fuel in the short term and alternative fuel systems can suffer. Our focus is not with the rigs doing the drilling inherent in oil exploration and requiring significant capital costs, but on the completed wells where existing production is far less sensitive to oil price volatility than is exploration. We believe that our installed base of flare gas fueled generators to the existing number of wells leaves us with significant future opportunities for our power systems in this market category, especially as oil prices rebound.

We are continuing to develop relationships with oil and gas companies for their well head jacks, compressors and power generators. We provide pre-certified, as opposed to site-certified, power systems. Site certification is a tedious and costly process for oil and gas equipment OEMs that can take many hours to source components and integrate them into existing fuel system hardware (if even possible).

Material Handling — Forklift Trucks
The material handling market category includes forklift trucks and other mobile products used for movement, handling and storage of materials within a facility or at a specific location. We provide spark-ignited power systems into the high volume 1.5, 3.5 and 5 ton capacity forklift markets, and may expand production in the future to support the 8 and 10 ton forklift markets in connection with anticipated increases in diesel prices resulting from regulations on diesel engines that took effect in 2015.
Demand is currently strong in the United States for our material handling power systems as a result of emission and OSHA regulations. Based upon data supplied by Power Systems Research, Inc., we believe that, in the United States, nearly 100% of the indoor forklift market uses spark-ignited liquid propane gas or electric powered units (with approximately equal market shares), in contrast to Asian and European forklift markets which currently use diesel in excess of 80% of all applications. In connection with the implementation of EPA Tier 4 and European Stage IV regulations, and the resulting price increases related to the compliance of diesel engines with these regulations, we expect foreign markets for spark-ignited liquid propane gas power systems to grow. We expect this growth to drive increased international demand for our power systems.

Aerial Work Platforms
The aerial work platforms market category consists of aerial work platforms, or machines used to provide access to areas typically inaccessible because of their height. Rental companies represent a majority of all purchasers in this industry category. We currently sell our liquid propane gas/gasoline dual fuel power systems to aerial work platform OEMs.

As a result of the increase in diesel engine pricing related to the implementation of EPA Tier 4 regulations, we expect to see an increase in the number of OEMs in the aerial work platforms market which consider our liquid propane gas and gasoline powered power systems as an alternative to diesel powered power systems.

Industrial Sweepers
The industrial indoor sweeper market category consists of machines that clean and sweep various indoor surfaces. The power systems for this market category use both spark-ignited and diesel engines, as well as electric motors. We currently sell our 30 to 80 horsepower liquid propane gas and gasoline power systems to industrial indoor sweeper OEMs.

Arbor Products
The arbor products market category includes wood chippers and grinders. We currently provide engines to four of the largest OEMs of wood chippers in the United States. We also design and manufacture our own proprietary power take-off clutch, which may be applied to any of our arbor product power systems.

Other Industry Categories
We provide power systems within other industrial OEM markets, including welding, airport ground support, agricultural, turf, construction and irrigation.

Power Systems for On-Road and Off-Road equipment
We have developed an internally designed, state-of-the-art, 8.8 liter fuel flexible engine that we sell into both the industrial market (off-road) and the truck and bus market (on-road). This unique engine has been designed to be easily integrated as a drop-in solution for both off-road and on-road OEM applications.
