Competitive Strengths

High-precision manufacturing capabilities

We believe our ability to produce high-precision parts at high production volumes is among the best in the market. Our technology platform consists of high precision machining, progressive stamping, laser welding, material science, assembly, and design optimization. In-house tool design and process know-how create trade secrets that enable consistent production tolerances of less than one micron while producing millions of parts per day. Parts are manufactured to application-specific customer design and co-design standards that are developed for a specific use. The high-precision capabilities are part of our zero-defect design process, which seeks to eliminate variability and manufacturing defects throughout the entire product lifecycle. We believe our production capabilities provide a competitive advantage as few other manufacturers are capable of meeting tolerance demands the volume level requested by our customers. As the need for tight-tolerance precision parts, subassemblies, and devices continues to increase, we believe that our production capabilities will place us at the forefront of the industry. We have differentiated ourselves among our competitors by providing customers engineered solutions and a broad reach and breadth of manufacturing capabilities. We believe it is for these reasons, and because of our proven ability to produce high-quality, precision parts and components on a cost-effective basis, that customers choose us to meet their manufacturing needs.

Differentiated, system-critical products

The tight-tolerance and high-quality nature of our precision products is specifically suited for use in the most demanding applications that require superior reliability. Our products are critical components to the operation and reliability of larger mechanical and electrical systems. Precision parts are difficult to manufacture and the high cost of failure motivates our customers to focus on quality. Our products are developed for specific uses within critical systems and are typically designed in conjunction with the system designer. Our parts are often qualified for, or specified in, customer designs, reducing the ability for customers to change suppliers.

Our ability to make products with tight-tolerance and extreme precision requirements enables our customers to satisfy the critical functionality and performance requirements of their products. We are included in customer designs and deployed in

critical systems that involve high cost of failure applications and significant regulatory certification processes, including those for the Underwriters Laboratories.

Complete product lifecycle focus

Our engineering expertise and deep knowledge of precision manufacturing processes adds proprietary value throughout the complete lifecycle of our products. Our in-house engineering team works closely with our customers to provide parts that meet specific design specifications for a given application. The relationship with the customer begins early in the conceptual design process when we provide feedback on potential cost, manufacturability, and estimated reliability of the parts. Part designs are then prototyped, tested, and qualified in coordination with the customer design process before going to full-scale production. The close working relationship with our customers early in the product lifecycle helps to secure business, increase industry knowledge, and develop significant trade secrets. Performance verification, product troubleshooting, and post-production engineering services further deepen relationships with our customers as well as provide additional industry knowledge that is applicable to future design programs and provide continuous manufacturing process improvement.

Prototype products are developed for testing, and process validation procedures are instituted. In certain instances, we will file for regulatory production approval and include the customer’s proprietary processes, further reducing supplier changes. We will assist the customer with continuous supply chain management and comprehensive customer support for the lifetime of the product and continuously seek to identify new operational efficiencies to reduce the product’s cost and improve its quality. Once our solution is designed into a platform, it is often embedded through the multi-year manufacturing lifecycle and has a competitive advantage in supporting subsequent platforms. As an added benefit, customers generally fund development, prototypes, and manufacturing tooling expenses. This discourages supplier changes and drives recurring revenue for us.

Long-term blue-chip customer base

We maintain relationships with hundreds of customers around the world. Our customers are typically sophisticated, engineering-driven, mechanical and electrical systems manufacturers with long histories of product development and reputations for quality. We have no significant retail exposure, which limits volatility and provides enhanced sales visibility. Relationships with many of our largest customers, in terms of revenue, average more than ten years. We have significant exposure to emerging markets in Asia, South America, and Europe through these global customers as well as key local manufacturers. The diverse nature, size, and reach of our customer base provides resistance to localized market and geographic fluctuations and helps stabilize overall product demand.

Strategic global footprint

Our 27 facilities, on four continents, are strategically located to serve our customer base and provide local service and expertise. Our global footprint provides flexibility to locally supply identical products for global customers, reducing shipping time and expense, allowing us to match costs to revenue and to capitalize on industry localization trends. In total, we operate more than 1.5 million square feet of manufacturing space. North America constitutes the largest portion of our manufacturing operations with facilities in the U.S. and Mexico which are strategically located to serve major customers in those markets. Our foreign facilities are located in regional manufacturing hubs in France, Poland, China, and Brazil, and primarily serve global customers in those markets. We believe that the Chinese and South American facilities have significant growth potential as local customer bases expand and the markets for high-precision products grow in those regions.

Raw Materials

Mobile Solutions

Mobile Solutions produces products from a wide variety of metals in various forms from various sources located in North America, Europe, South America, and Asia. Basic types include hot rolled steel, cold rolled steel (both carbon and alloy), stainless steel, steel alloys, copper alloys, extruded aluminum, aluminum alloy bar, gray and ductile iron castings, hot and cold forgings, titanium alloys, plastics, and mechanical tubing. Material is purchased directly from the raw material suppliers, some of which may be directed by customers.

Power Solutions

Power Solutions uses a wide variety of metals in various forms, including precious metals like gold, silver, palladium, and platinum, as well as copper, copper alloys, brass, brass alloys, inconel, steel alloys and plastics. Through our diverse network of suppliers, we minimize supplier concentration risk and provide a stable supply of raw materials at competitive pricing. This group also procures metal stampings from several domestic and foreign suppliers. Power Solutions bases purchase decisions on quality, service and price. Generally, we do not enter into long-term supply contracts with our suppliers or commit to maintain minimum monthly purchases of materials. However, we carefully manage raw material price volatility, particularly with respect to precious metals, through the use of consignment agreements, which allow us to buy the precious metals on the same day customer shipments are priced, thereby minimizing risk of price changes from procurement to product shipment.

Supply and Cost Pressures

In each of our segments, we at times have been affected by upward price pressure on the raw materials we purchase due to changes in commodity pricing. In general, we pass through material cost fluctuations to our customers in the form of changes in selling price. Most of the raw materials we use are purchased from various suppliers and are typically available from numerous sources, some of which are located in China and Europe. Supply chain disruptions, resulting in supply shortages and higher shipping charges, have impacted our suppliers and could continue to impact our ability to maintain supplies of products and the costs associated with obtaining raw materials and key components. In addition, geopolitical conflicts, tariffs, inflation and other factors have made the price of metals more volatile. We continue to monitor impacts on our supply chain in order to maintain regular and timely supply of raw materials to our business segments.

Patents, Trademarks and Licenses

We have one U.S. patent and numerous trademarks for various trade names throughout the world. However, we cannot be certain that we would be able to protect and enforce our intellectual property rights against third parties, and if we cannot do so, we may face increased competition and diminished net sales.

Furthermore, third parties may assert infringement claims against us based on their patents or other intellectual property, and we may have to pay substantial damages and/or redesign our products if we are ultimately found to infringe. Even if such intellectual property claims against us are without merit, investigating and defending these types of lawsuits takes significant time, may be expensive and may divert management attention from other business concerns.

Additionally, we rely on certain data and processes, including trade secrets and know-how, and the success of our business depends, to some extent, on such information remaining confidential. Each officer is subject to a non-competition and confidentiality agreement that seeks to protect this information. Additionally, all employees are subject to company code of ethics policies that prohibit the disclosure of information critical to the operations of our business.

Seasonal Nature of Business

General economic conditions impact our business and financial results, and certain businesses experience seasonal and other trends related to the industries and end markets that they serve. For example, European sales are often weaker in the summer months as customers slow production, automotive sales tend to slow in July and December, and sales to original equipment manufacturers are often stronger immediately preceding and following the launch of new products. However, as a whole, we are not materially impacted by seasonality.

Government Regulations and Environmental Matters

Our operations are subject to extensive federal, state, local, and foreign regulatory requirements, including those intended to protect public health and the environment. In the U.S. certain of our products and operations are regulated by the Environmental Protection Agency. Similar regulations have been adopted by authorities in foreign countries where we sell our products, and by state and local authorities in the U.S. In order to conduct our operations in compliance with these laws and regulations we must obtain and maintain numerous permits, approvals and certificates from various federal, state, local, and foreign governmental authorities.

We are also required to comply with increasingly complex and changing laws and regulations enacted to protect business and personal data in the U.S. and other jurisdictions regarding privacy, data protection, and data security, including those related to the collection, storage, use, transmission, and protection of personal information and other customer, supplier or employee data. Such privacy and data protection laws and regulations, and the interpretation and enforcement of such laws and regulations, are continuously developing and evolving and there is significant uncertainty with respect to how compliance with these laws and regulations may evolve and the costs and complexity of future compliance.

Based on information compiled to date, management believes that our current operations are in compliance with applicable governmental laws and regulations, the violation of which could have a material adverse effect on our business and financial condition. As of the date hereof, compliance with these laws and regulations has not had a material effect on our capital expenditures, results of operations, and competitive position.
