critical components for fuel systems, engines and transmissions, power steering systems and electromechanical motors. This expertise has been gained through investment in technical capabilities, processes and systems, and skilled program management and product launch capabilities.

Research and Development

As a part of our strategic plan, we are in the process of enhancing our research and development efforts. We will initially focus on adjacent markets, manufacturing process enhancements and continuing to improve our product quality. In addition, we intend to develop patented products that can be presented to and sold by our customers. Patent applications for two medical devices were filed in 2015, a surgical knife and impactor adapter and screw assembly. In general, these research and development efforts will entail using dedicated internal experts and resources. The amounts spent on research and development activities by us during each of the last three fiscal years are not material and are expensed as incurred.

Customers

Our products are supplied primarily to manufacturers for use in a broad range of industrial applications, including automotive, electrical, agricultural, construction, machinery, heavy truck, rail, medical, aerospace and defense, HVAC, fluid power and diesel engines. Our top ten customers account for approximately 53% of our revenue. Sales to each of these top ten customers are made to multiple customer locations and divisions throughout the world. Only one of these customers, AB SKF (“SKF”), had sales levels that were over 10% of total net sales. Sales to various U.S. and foreign divisions of SKF accounted for approximately 16% of net sales in 2015. In 2015, 56% of our products were sold to customers in North America, 26% to customers in Europe, 13% to customers in Asia and the remaining 5% to customers in South America.

We sell our products to most of our largest customers under either sales contracts or agreed upon commercial terms. In general, we pass through material cost fluctuations when incurred to our customers in the form of changes in selling prices. We ordinarily ship our products directly to customers within 60 days, and in many cases, during the same calendar month of the date on which a sales order is placed. Accordingly, we generally have an insignificant amount of open (backlog) orders from customers at month end.

See Note 12 of the Notes to Consolidated Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations” for additional segment financial information.

Sales and Marketing

A primary emphasis of our marketing strategy is to expand key customer relationships by offering high quality, high-precision, application-specific customer solutions with the value of a single supply chain partner for a wide variety of products and components. Due to the technical nature of many of our products, our engineers and manufacturing management personnel also provide technical sales support functions, while internal sales employees handle customer orders and other general sales support activities. Each of our groups use a distinct direct sales force supported by senior segment management and engineering involvement. Our Precision Bearing Components Group marketing strategy focuses on our ability to provide consistent, high quality products that meet the most precise specifications of leading global brands. Our marketing strategy for the Precision Engineered Products Group and the Autocam Precision Components Group is to offer custom manufactured, high quality, precision products to markets with high value-added characteristics at competitive price levels. This strategy focuses on relationships with key customers that require the production of technically difficult parts and assemblies, enabling us to take advantage of our strengths in custom product development, equipment and tool design, component assembly and machining processes.

Competition

Precision Bearing Components Group

Our Precision Bearing Components Group operates in intensely competitive markets. Our primary domestic competitor is Hoover Precision Products, Inc., a wholly owned subsidiary of Tsubaki Nakashima Co., LTD. Our primary foreign competitors are Amatsuji Steel Ball Manufacturing Company, Ltd. (Japan), a wholly owned division of NSK LTD., Tsubaki Nakashima Co., LTD (Japan) and Jiangsu General Ball and Roller Co., LTD (China). Additionally, we compete with bearing manufacturers’ in-house (captive) production.

We believe that competition within the Precision Bearing Components Group is based principally on quality, price and the ability to consistently meet customer delivery requirements. Management believes that our competitive strengths are our precision manufacturing capabilities, our wide product assortment, our reputation for consistent quality and reliability, our global manufacturing footprint and the productivity of our workforce.

Precision Engineered Products Group

Our Precision Engineered Products Group also operates in intensely competitive markets. We must compete with numerous companies in each industry market segment. Many of these companies have substantially greater financial resources than we do and many currently offer competing products nationally and internationally.

Our primary competitors in the plastic bearing retainer market are Nakanishi Manufacturing Corporation, and Pressey. Domestically, National, Nypro Inc., Thermotech, GW Plastics, C&J Industries and Nyloncraft are amongst the largest players in the precision plastic components markets. Our primary competitors in the medical device

market are Tecomet, Inc., Lake Region Medical, Inc., and Vention Medical, Inc. Our primary competitors in the electrical market are Deringer-Ney, Inc., Doduco GmbH and Metalor Technologies International. Our primary competitors in the automotive and aerospace market are Interplex Industries, Inc. and Accu-Mold, LLC.

We believe that competition within the plastic injection molding, plastic bearing retainer, precision plastic components, medical device, electrical, automotive and aerospace markets is based principally on quality, price, design capabilities and speed of responsiveness and delivery. Management believes that our competitive strengths are product development, tool design, fabrication, and tight tolerance molding processes. With these strengths, we have built our reputation in the marketplace as a quality producer of technically difficult products.

Autocam Precision Components Group

In the market in which our Autocam Precision Components Group operates, internal production of components by our customers can impact our business as the customers weigh the risk of outsourcing strategically critical components or producing in-house. Our primary outside competitors are Häring, A. Berger, C&A Tool, American Turned Products, Camcraft and AB Heller. We generally win new business on the basis of technical competence and our proven track record of successful product development.

Raw Materials

Precision Bearing Components Group

The primary raw material used in our core ball and roller business of the Precision Bearing Components Group is 52100 Steel, which is high quality chromium steel. Our other steel requirements include metal strip, stainless steel, and type S2 rock bit steel.

The Precision Bearing Components Group businesses purchase substantially all of their 52100 Steel requirements from suppliers in Europe and Japan, and all of their metal strip requirements from European suppliers and traders. We purchase steel on the basis of composition, quality, availability and price. For precision steel balls, the pricing arrangements with our suppliers are typically subject to adjustment every three to six months in North America and contractually adjusted on an annual basis within the European locations for the base steel price and quarterly for surcharge adjustments. If any of our current suppliers were unable to supply 52100 Steel to us, higher costs and/or production interruptions could occur as a result of obtaining 52100 Steel from alternate sources. Our operating results would be negatively affected in the event that North American or European governments impose any significant quotas, tariffs or other duties or restrictions on the import of such steel, if the U.S. dollar decreases in value relative to foreign currencies or if supplies available to us would significantly decrease.

Precision Engineered Products Group

The Precision Engineered Products Group uses a wide variety of metals in various forms, including precious metals like gold, silver, palladium and platinum. 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 resins and metal stampings from several domestic and foreign suppliers.

For the Precision Engineered Products Group, we base purchase decisions on quality, service and price. Generally, we do not enter into written 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. In effect, we lease the precious metals for our own stock and buy the raw materials only on the same day customer shipments are priced, thereby eliminating speculation. In addition, our products with precious metal content are priced with a margin on the raw material cost to further protect against raw material price volatility and to provide incremental profit.

Autocam Precision Components Group

The Autocam Precision Components Group produces products from a wide variety of metals in various forms from various sources located in the North America, Europe and Japan. Basic types include hot rolled steel, cold rolled steel (both carbon and alloy), stainless, extruded aluminum, die cast aluminum, gray and ductile iron castings, hot and cold forgings and mechanical tubing. Some material is purchased directly under contracts, some is consigned by the customer, and some is purchased directly from the steel mills.

Table of Contents

In each of our three segments, we have historically been affected by upward price pressure on steel principally due to general increases in global demand. In general, we pass through material cost fluctuations to our customers in the form of changes in selling price.

Patents, Trademarks and Licenses

Historically, we have not owned any U.S. or foreign patents, trademarks or licenses that are material to our business; however, in connection with the PEP Acquisition, we acquired six U.S. patents, four patent applications and trademarks for various trade names. Furthermore, we intend to develop patented products that can be presented to and sold by our customers.

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 executive 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

Historically, due to a substantial portion of sales to European customers, seasonality has been a factor for our business in that some European customers typically reduce their production activities during the month of August.

Regulatory Matters

Environmental Compliance

Our operations and products are subject to extensive federal, state and local regulatory requirements both domestically and abroad relating to pollution control and protection of the environment. These laws and regulations govern, among other things, discharges to air or water, the generation, storage, handling, and use of automotive hazardous materials and the handling and disposal of hazardous waste generated at our facilities. Under such laws and regulations, we are required to obtain permits from governmental authorities for some of our operations. If we violate or fail to comply with these laws, regulations or permits, we could be fined or otherwise sanctioned by regulators. Under some environmental laws and regulations, we could also be held responsible for all the costs relating to any contamination at its past or present facilities and at third-party waste disposal sites. We maintain a compliance program to assist in preventing and, if necessary, correcting environmental problems. In the Precision Bearing Components Group, the Kysucke plant, the Veenendaal plant, the Pinerolo plant and Kunshan plant are ISO 14000 or 14001 certified and all received the EPD (Environmental Product Declaration), except for the Veenendaal plant’s stamped metal parts business.

Based on information compiled to date, management believes that our current operations are in substantial compliance with applicable environmental laws and regulations, the violation of which could have a material adverse effect on our business and financial condition. We have assessed conditional asset retirement obligations and have found them to be immaterial to the consolidated financial statements. We cannot assure that currently unknown matters, new laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future. More specifically, although we believe that we dispose of waste in material compliance with applicable environmental laws and regulations, we cannot be certain that we will not incur significant liabilities in the future in connection with the clean-up of waste disposal sites.

FDA Compliance

As a contract manufacturer of medical devices, certain of our subsidiaries, including PEP, are required to register as such with the U.S. Food and Drug Administration (“FDA”). Each of our facilities that manufacture finished medical devices is registered with the FDA. To maintain our registration, we deploy a robust quality management system across all of our manufacturing facilities.

With respect to medical products that we are specifically developing to sell to our customers, before these devices can be marketed, we will seek to obtain a marketing clearance from the FDA under Section 510(k) of the United States Federal Food, Drug, and Cosmetic Act. The FDA typically grants a 510(k) clearance if the applicant can establish that the device is substantially equivalent to a predicate device. Clearance under Section 510(k) typically takes about three months from the date of submission.

We may not realize all of the anticipated benefits from the six acquisitions closed since January 1, 2014 or any future strategic portfolio acquisition, or those benefits may take longer to realize than expected.

Our ability to realize the anticipated benefits of the six acquisitions closed since January 1, 2014 will depend, to a large extent, on our ability to integrate these businesses and any future strategic portfolio acquisitions. The integration process may disrupt the businesses and, if implemented ineffectively, would preclude realization of the full benefits expected. The difficulties of combining the operations of the acquired companies include, among others:

Many of these factors will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy, which could materially impact our business, financial condition, or results of operations.

Additionally, we incurred a significant amount of debt in connection with these six acquisitions. Finally, in relation to these acquisitions we have significantly higher amounts of intangible assets, including goodwill. These intangible assets will be subject to impairment testing and we could incur a significant impact to our financial statements in the form of an impairment if assumptions and expectations related to these five acquisitions are not realized.

A recession impacting our end markets or the geographic regions in which we or our customers operate could have a material adverse effect on our ability to finance our operations and implement our growth strategy.

During the three month period ended December 31, 2008 and the year ended December 31, 2009, we experienced a sudden and significant reduction in customer orders driven by reductions in automotive and industrial end market demand across all our businesses. Additionally, during the latter part of 2011 and all of 2012, we experienced the impacts of a European recession in our European businesses. Prior to this time, we had never been affected by a recession that had impacted both of our key geographic markets of the U.S. and Europe simultaneously. If we are impacted by a global recession in the future, this could have a material adverse effect on our business, financial condition, results of operations and cash flows from operations and could lead to additional restructuring and/or impairment charges being incurred and our ability to implement our growth strategy. However, we believe we would be in a much better position to weather any recession or economic downturn given the actions taken to permanently reduce our cost base including closing or ceasing operations at four former manufacturing locations.

The demand for our products is cyclical, which could adversely impact our revenues.

The end markets for fully assembled bearings and industrial and automotive components are cyclical and tend to decline in response to overall declines in industrial and automotive production. As a result, the market for the bearing components and precision metal and industrial plastic products we sell is also cyclical and impacted by overall levels of industrial and automotive production. Our sales have been, and can be in the future, negatively affected by adverse conditions in the industrial and/or automotive production sectors of the economy or by adverse global or national economic conditions generally. Additionally, any inflation in oil and any resulting increase in gasoline prices could have a negative impact on demand for our products as a result of consumer and corporate spending reductions.

We depend on a very limited number of foreign sources for our primary raw material and are subject to risks of shortages and price fluctuation.

The steel that we use to manufacture our precision bearing components is of an extremely high quality and is available from only a limited number of producers on a global basis. Due to quality constraints in the U.S. steel industry, we obtain substantially all of the steel used in our U.S. operations of our Precision Bearing Components Group from non-U.S. suppliers. In addition, we obtain most of the steel used in our European operations from a single European source. If we had to obtain steel from sources other than our current suppliers, we could face higher prices and automotive costs, increased duties or taxes and shortages of steel. Problems in obtaining steel, particularly 52100 chrome steel in the quantities that we require, on commercially reasonable terms could increase our costs, adversely impact our ability to operate our business efficiently and have a material adverse effect on our revenues and operating and financial results.

We depend heavily on a relatively limited number of customers, and the loss of any major customer would have a material adverse effect on our business.

Sales to various U.S. and foreign divisions of SKF, one of the largest bearing manufacturers in the world, accounted for approximately 16% of consolidated net sales in 2015. No other customers accounted for more than 10% of sales. During 2015, sales to various U.S. and foreign divisions of our ten largest customers accounted for approximately 53% of our consolidated net sales. The loss of all or a substantial portion of sales to these customers would cause us to lose a substantial portion of our revenue and would lower our operating profit margin and cash flows from operations.

Our substantial indebtedness could adversely affect our financial condition and results of operations.

We are highly leveraged. As of December 31, 2015, we had approximately $820 million of indebtedness outstanding, and had an additional $90.9 million available for borrowing under our debt agreements. Our high degree of leverage could have important consequences, including:

11

Table of Contents

If any one of these events were to occur, our financial condition and results of operations could be materially and adversely affected. For more information regarding our indebtedness, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.”

Despite our high indebtedness level, we will still be able to incur substantial additional amounts of debt, which could further exacerbate the risks associated with our substantial indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. Although our debt agreements contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions, and under certain circumstances, the amount of indebtedness that could be incurred in compliance with these restrictions could be substantial. If new debt is added to our and our subsidiaries’ debt levels, the related risks that we now face would increase.

Our debt agreements contain restrictions that will limit our flexibility in operating our business.

Our debt agreements contain various covenants that limit our ability to engage in specified types of transactions. These covenants will limit our ability to, among other things:

In addition, the restrictive covenants in our debt agreements require us to maintain specified financial ratios and satisfy other financial condition tests. Our ability to meet those financial ratios and tests will depend on our ongoing financial and operating performance, which, in turn, will be subject to economic conditions and to financial, market, and competitive factors, many of which are beyond our control. A breach of any of these covenants could result in a default under one or more of our debt agreements, and permit our lenders to cease making loans to us under our credit facilities. Furthermore, if we were unable to repay the amounts due and

12

Table of Contents

payable under our secured debt agreements, our secured lenders could proceed against the collateral granted to them to secure our borrowings. Such actions by the lenders could also cause cross defaults under our other debt agreements.

We may not be able to generate sufficient cash to service all of our indebtedness and we may not be able to refinance our debt obligations as they mature.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

As our debt obligations mature or if our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital, or restructure or refinance our indebtedness, including the Senior Notes. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of our existing or future debt instruments may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

Work stoppages or similar difficulties could significantly disrupt our operations, reduce our revenues and materially affect our earnings.

A work stoppage at one or more of our facilities could have a material adverse effect on our business, prospects, financial condition, results of operations or cash flows from operations. Also, if one or more of our customers were to experience a work stoppage, that customer would likely halt or limit purchases of our products, which could have a material adverse effect on our business, prospects, financial condition and results of operations or cash flows from operations.

We operate in and sell products to customers outside the U.S. and are subject to several risks related to doing business internationally.

Because we obtain a majority of our raw materials from overseas suppliers, actively participate in overseas manufacturing operations and sell to a large number of international customers, we face risks associated with the following:

13

Table of Contents

These and other risks may also increase the relative price of our products compared to those manufactured in other countries, thereby reducing the demand for our products in the markets in which we operate, which could have a material adverse effect on our business, financial condition, results of operations and cash flows from operations.

In addition, we could be adversely affected by violations of the Foreign Corrupt Practices Act (the “FCPA”) and similar worldwide anti-bribery laws, as well as export controls and economic sanction laws. The FCPA and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Our policies mandate compliance with these laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. We cannot assure you that our internal controls and procedures will always protect us from the improper acts committed by our employees or agents. If we are found to be liable for FCPA, export control or sanction violations, we could suffer from criminal or civil penalties or other sanctions, including loss of export privileges or authorization needed to conduct aspects of our international business, which could have a material adverse effect on our business, prospects, financial condition, results of operations and cash flows from operations.

In addition, due to the typical slower summer manufacturing season in Europe, we expect that revenues in the third fiscal quarter of each year will be lower than in the other quarters of the year.

We have international operations that are subject to foreign economic uncertainties and foreign currency fluctuation.

Approximately 39% of our revenues are denominated in foreign currencies, which may result in additional risk of fluctuating currency values and exchange rates and controls on currency exchange. Changes in the value of foreign currencies could increase our U.S. dollar costs for, or reduce our U.S. dollar revenues from, our foreign operations. Any increased costs or reduced revenues as a result of foreign currency fluctuations could affect our profits. In 2015, the U.S. dollar continued to strengthen compared to the euro, which adversely affected our revenue by $39.1 million. Further strengthening of the U.S. dollar may adversely affect our financial condition and results of operations.

Environmental, health and safety laws and regulations impose substantial costs and limitations on our operations; environmental compliance may be more costly than we expect, and any adverse regulatory action may materially adversely affect our business.

We are subject to extensive federal, state, local and foreign environmental, health and safety laws and regulations concerning matters such as air emissions, wastewater discharges, solid and hazardous waste handling and disposal and the investigation and remediation of contamination. The risks of substantial costs, liabilities and limitations on our operations related to compliance with these laws and regulations are an inherent part of our business, and future conditions may develop, arise or be discovered that create substantial environmental compliance or remediation liabilities and costs.

Compliance with environmental, health and safety legislation and regulatory requirements may prove to be more limiting and costly than we anticipate. To date, we have committed significant expenditures in our efforts to achieve and maintain compliance with these requirements at our facilities, and we expect that we will continue to make significant expenditures related to such compliance in the future. From time to time, we may be subject to legal proceedings brought by private parties or governmental authorities with respect to environmental matters, including matters involving alleged noncompliance with or liability under environmental, health and safety laws, property damage or personal injury. New laws and regulations, including those which may relate to emissions of greenhouse gases, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or the imposition of new clean-up requirements could require us to incur costs or become the basis for new or increased liabilities that could have a material adverse effect on our business, prospects, financial condition or results of operations.

Our medical devices are subject to regulation by numerous government agencies, including the FDA and comparable agencies outside the U.S. To varying degrees, each of these agencies requires us to comply with laws and regulations governing the development, testing, manufacturing, labeling, marketing and distribution of our medical devices. We cannot guarantee that we will be able to obtain marketing clearance for our new products or enhancements or modifications to existing products. If such approval is obtained, it may:

14

Table of Contents

Both before and after a product is commercially released, we have ongoing responsibilities under FDA regulations. We are also subject to periodic inspections by the FDA to determine compliance with the FDA’s requirements, including primarily the quality system regulations and medical device reporting regulations. The results of these inspections can include inspectional observations on FDA’s Form-483, warning letters, or other forms of enforcement. Since 2009, the FDA has significantly increased its oversight of companies subject to its regulations, including medical device companies, by hiring new investigators and stepping up inspections of manufacturing facilities. The FDA has recently also significantly increased the number of warning letters issued to companies. If the FDA were to conclude that we are not in compliance with applicable laws or regulations, or that any of our medical devices are ineffective or pose an unreasonable health risk, the FDA could ban such medical devices, detain or seize adulterated or misbranded medical devices, order a recall, repair, replacement or refund of such devices, refuse to grant pending pre-market approval applications or require certificates of foreign governments for exports, and/or require us to notify health professionals and others that the devices present unreasonable risks of substantial harm to the public health. The FDA may also impose operating restrictions on a company-wide basis, enjoin and/or restrain certain conduct resulting in violations of applicable law pertaining to medical devices, and assess civil or criminal penalties against our officers, employees, or us. The FDA may also recommend prosecution to the Department of Justice. Any adverse regulatory action, depending on its magnitude, may restrict us from effectively marketing and selling our products.

Foreign governmental regulations have become increasingly stringent and more common, and we may become subject to more rigorous regulation by foreign governmental authorities in the future. Penalties for a company’s non-compliance with foreign governmental regulation could be severe, including revocation or suspension of a company’s business license and criminal sanctions. Any domestic or foreign governmental law or regulation imposed in the future may have a material adverse effect on us.

Failure of our products could result in a product recall.

The majority of our products are components of our customers’ products that are used in the automotive industry and other critical industrial applications. A failure of our components could lead to a product recall. If a recall were to happen as a result of our components failing, we could bear a substantial part of the cost of correction. In addition to the cost of fixing the parts affected by the component, a recall could result in the loss of a portion of or all of the customer’s business. A successful product recall claim requiring that we bear a substantial part of the cost of correction or the loss of a key customer could have a material adverse effect on our business, prospects, financial condition, results of operations and cash flows from operations.

Our growth strategy depends in part on companies outsourcing critical components, and if outsourcing does not continue, our business could be adversely affected.

Our growth strategy depends in part on major customers continuing to outsource components and expanding the number of components being outsourced. This requires manufacturers to depart significantly from their traditional methods of operations. If major customers do not continue to expand outsourcing efforts or determine to reduce their use of outsourcing, our ability to grow our business could be materially adversely affected.

Our market is highly competitive, and many of our competitors have significant advantages that could adversely affect our business.

The global markets for precision bearing components and precision metal and plastic components are highly competitive, with a majority of production represented by the captive production operations of large manufacturers,    and the balance represented by independent manufacturers. Captive manufacturers make components for internal use and for sale to third parties. All of the captive manufacturers, and many independent manufacturers, are significantly larger and have greater resources than we do. Our competitors are continuously exploring and implementing

15

Table of Contents

improvements in technology and manufacturing processes in order to improve product quality, and our ability to remain competitive will depend, among other things, on whether we are able to keep pace with such quality improvements in a cost effective manner. Due to this competitiveness, we may not be able to increase prices for our products to cover cost increases. In many cases we face pressure from our customers to reduce prices, which could adversely affect our business, financial condition, results of operations and cash flows from operations. In addition, our customers may choose to purchase products from one of our competitors rather than pay the prices we seek for our products, which could adversely affect our business, prospects, financial condition, results of operations and cash flows from operations.

Our production capacity has been expanded geographically in recent years to operate in the same markets as our customers.

We have expanded our precision bearing components production facilities and capacity over the last several years. Historically, precision bearing component production facilities have not always operated at full capacity. Over the past several years, we have undertaken steps to address a portion of the capacity risk including closing or ceasing operations at certain plants and downsizing employment levels at others. As such, the risk exists that our customers may exit the geographic markets in which our production capacity is located and/or develop vendors in lower cost countries in which we do not have production capacity.

The price of our common stock may be volatile.

The market price of our common stock could be subject to significant fluctuations and may decline. Among the factors that could affect our stock price are:

The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In addition, due to the market capitalization of our stock, our stock tends to be more volatile than large capitalization stocks that comprise the Dow Jones Industrial Average or Standard and Poor’s 500 Index.

Provisions in our charter documents and Delaware law may inhibit a takeover, which could adversely affect the value of our common stock.

Our certificate of incorporation and bylaws, as well as Delaware corporate law, contain provisions that could delay or prevent a change of control or changes in our management that a stockholder might consider favorable and may prevent shareholders from receiving a takeover premium for their shares. These provisions include, for example, a classified board of directors and the authorization of our board of directors to issue up to five million preferred shares without a stockholder vote. In addition, our certificate of incorporation provides that stockholders may not call a special meeting.

We are a Delaware corporation subject to the provisions of Section 203 of the Delaware General Corporation Law, an anti-takeover law. Generally, this statute prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years after the date of the transaction in which such person became an interested stockholder, unless the business combination is approved in a prescribed manner. A business combination includes a merger, asset sale or other transaction resulting in a financial benefit to the stockholder. We anticipate that the provisions of Section 203 may encourage parties interested in acquiring us to negotiate in advance with our board of directors, because the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction that results in the stockholder becoming an interested stockholder.

These provisions apply even if the offer may be considered beneficial by some of our stockholders. If a change of control or change in management is delayed or prevented, the market price of our common stock could decline.

We may be unable to integrate PEP’s businesses with ours successfully or realize the anticipated synergies and other benefits of the PEP Acquisition or do so within the anticipated timeframe.

We will be required to devote significant management attention and resources to integrating the operations and business practices of PEP with our existing operations and business practices. Potential difficulties we may encounter as part of the integration process include the following:

These potential difficulties could adversely affect our and the managers of PEP’s ability to maintain relationships with customers, suppliers, employees and other constituencies and the ability to achieve the anticipated benefits of the PEP Acquisition, and could adversely affect our business, prospects, financial results or operations.

We may be unable to realize the anticipated cost or capital expenditure savings or may incur additional and/or unexpected costs in order to realize them.

There can be no assurance that we will be able to realize the anticipated cost or capital expenditure savings from the PEP Acquisition in the anticipated amounts or within the anticipated timeframes or at all. We anticipate

17

Table of Contents

implementing a series of cost savings initiatives that we expect to result in recurring, annual run-rate cost savings. We expect to incur one-time, non-recurring costs to achieve such synergies, including certain costs during 2015 and 2016. These or any other cost or capital expenditure savings that we realize may differ materially from our estimates. We cannot provide assurances that these anticipated savings will be achieved or that our programs and improvements will be completed as anticipated or at all. In addition, any cost savings that we realize may be offset, in whole or in part, by reductions in revenues or through increases in other expenses.

Our projections and assumptions related to cost savings are based on our current estimates, but they involve risks, uncertainties, projections and other factors that may cause actual results, performance or achievements to be materially different from any future results, performance or achievements, express or implied. Neither our independent auditors nor any other independent auditors, have examined, compiled or performed any procedures with respect to these projections, nor have they expressed any opinion, or any other form of assurance on such information or their achievability. Assumptions relating to our projections involve subjective decisions and judgments with respect to, among other things, the estimated impact of certain operational adjustments, including Six Sigma/OpEx optimization programs, product grouping and rationalization, facility rationalization and shared services cost savings and other cost and savings adjustments, as well as future economic, competitive, industry and market conditions and future business decisions, all of which are inherently uncertain and may be beyond the control of our management.

Failure to realize the expected costs savings and operating synergies related to the PEP Acquisition could result in increased costs and have an adverse effect on our business, prospects, financial results or operations.

Our future results could suffer if we cannot effectively manage our expanded operations following the PEP Acquisition.

As a result of the PEP Acquisition, the size of our operations were significantly increased. Our future success depends, in part, upon our ability to manage the expanded operations, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurance that we will be successful or that we will realize any operating efficiencies, cost savings, revenue enhancements or other benefits currently anticipated from the PEP Acquisition.

We may be unable to retain key employees as a result of the PEP Acquisition.

Our success will depend in part upon the ability to retain key former employees of PEP, as well as our key employees. Key employees may depart because of, among other things, issues relating to the uncertainty and difficulty of integration or a desire not to remain with us following the PEP Acquisition. Accordingly, no assurance can be given that we will be able to retain key employees to the same extent as in the past.

PEP operates in a different line of business from our historical business, and the PEP Acquisition is significantly larger than any other acquisition we have made to date. We may face challenges managing PEP as a new business and may not realize anticipated benefits.

The PEP Acquisition, our largest acquisition to date in terms of acquisition price, resulted in our being significantly engaged in lines of business of which we have little to no historical operations. Because we are entering into a new line of business, we may not have the expertise, experience and resources to pursue all of our businesses at once, or we may be unable to successfully operate the businesses. The administration of our businesses will require implementation of appropriate operations, management, compliance and financial reporting systems and controls. We may experience difficulties in effectively implementing these and other systems. PEP’s management team will require the focused attention of their management team, including a significant commitment of its time and resources. The need for management to focus on these matters could have a material and adverse impact on our revenues and operating results. If PEP’s operations are less profitable than we currently anticipate or if we do not have the experience, the appropriate expertise, or the resources to pursue all of our businesses, our business, prospects, financial results or operations may be materially and adversely affected.

We incurred substantial expenses related to the PEP Acquisition and expect to incur substantial expenses relating to the integration of our operations with PEP.

We expect to incur substantial expenses in connection with the Acquisition and the integration of our operations with PEP. There are a large number of processes, policies, procedures, operations, technologies and systems that must be

18

Table of Contents

integrated, including purchasing, accounting and finance, sales, payroll, pricing, marketing and benefits. While we have assumed that a certain level of expenses will be incurred, there are many factors beyond our control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These integration expenses may result in us taking significant charges against earnings following the consummation of the Acquisition, and the amount and timing of such charges are uncertain at present.

The following table sets forth the high and low closing sales prices of the common stock, as reported by NASDAQ for our two most recent fiscal years.

The following graph and table below compares the cumulative total shareholder return on our common stock with the cumulative total shareholder return of: (i) the Value Line Machinery Index (“Machinery Index”); (ii) the Standard & Poors 500 Stock Index; (iii) the Standard & Poors SmallCap 600; and (iv) a customized peer group, for the period from December 31, 2010 to December 31, 2015. The Machinery Index is an industry index comprised of 74 companies engaged in manufacturing of machinery and machine parts, a list of which may be obtained by writing to NN, Inc., Attention: Secretary, 207 Mockingbird Lane, Johnson City, Tennessee 37604. The customized peer group consists of the following companies, which we believe are in similar lines of business: Actuant Corporation, Altra Industrial Motion Corp., Ametek Inc., CIRCOR International, Inc., Colfax Corporation, Crane, Kaman Corporation, Park-Ohio Holdings Corp. and Worthington Industries, Inc. (collectively, the “Peer Group”). The following graph and table assumes that a $100 investment was made at the close of trading on December 31, 2010 in our common stock and in the Machinery Index, the Standard & Poors 500 Stock Index, the Standard & Poors SmallCap 600 and the Peer Group. We cannot assure you that the performance of our common stock will continue in the future with the same or similar trend depicted on the graph.

In our Annual Report on Form 10-K for the year ended December 31, 2014, we used the Standard & Poors 500 Stock Index as our broad equity market index and the Machinery Index as our line of business index for our performance graph comparison. However, we have determined that the Standard & Poors SmallCap 600 is a more appropriate broad equity market index because it has more companies that have a market capitalization similar to us. Additionally we have determined that the Peer Group is a more appropriate comparative group than the Machinery Index, as the companies comprising the Peer Group include diversified industrial manufacturers like NN. In light of the diversification of our end markets and the broadening of our portfolio of products, services and solutions over the last two years, primarily due to the acquisitions of Autocam and PEP, we believe the Peer Group is comprised of companies that better reflect our current business.

The following selected financial data has been derived from our audited financial statements. The selected financial data should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the audited Consolidated Financial Statements, including the Notes thereto.

The year ended December 31, 2015 was significantly impacted by certain costs related to the PEP Acquisition and to a lesser extent the Caprock acquisition completed in 2015, as well as the issuance of shares of our common stock. The total impact of these costs was $43.0 million (before tax) and $29.4 million (after tax). The balance sheet for the year ended December 31, 2015 includes the impact of these costs. With these acquisitions, we acquired current assets and total assets of $71.2 million and $741.6 million, respectively, and assumed current liabilities and total liabilities of $21.7 million and $111.3 million, respectively.

On July 1, 2015 we closed a registered follow-on offering of public common stock. The total number of shares of common stock sold was approximately 7.6 million at a public offering price of $24.00 per share. The net proceeds received from the offering, after deducting underwriter discounts, commissions and offering expenses, were approximately $173.1 million. Of these proceeds, $148.7 million was used for repayment of principal and interest on existing debt.

On October 19, 2015, concurrent with the PEP Acquisition, we: (i) entered into a new senior secured term loan facility in the amount of up to $525.0 million (with a $100.0 million accordion feature) and a seven year maturity (the “New Term Loan Credit Facility”); (ii) entered into a new senior secured revolving credit facility in the amount of up

23

Table of Contents

to $100.0 million with a five year maturity (the “New Senior Secured Revolving Credit Facility”, and together with the New Term Loan Credit Facility, the “New Senior Credit Facilities”); and (iii) issued $300.0 million of 10.25% senior notes due 2020 (the “Senior Notes”). Proceeds from the New Term Loan Credit Facility and the Senior Notes were used to finance the purchase price of the PEP Acquisition and pay down debt. The New Senior Credit Facilities replaced our existing credit facilities. On November 9, 2015, an incremental term loan of $50.0 million was drawn on the New Term Loan Credit Facility and the proceeds were used to repurchase approximately $50.0 million of the Senior Notes. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for more information. Additional details regarding the financing of the PEP acquisition may be found in our Current Report on Form 8-K filed with the Securities and Exchange Commission on October 20, 2015.

The year ended December 31, 2014 was significantly impacted by certain costs related to the Autocam acquisition and to a lesser extent the three other acquisitions completed in 2014. The total impact of these costs was $14.8 million (before tax) and $13.6 million (after tax). In addition, related to the Autocam acquisition, we discontinued use of certain trade names and incurred a $0.9 million impairment charge. The balance sheet for the year ended December 31, 2014 includes the impact of four acquisitions closed during 2014. With these acquisitions, we acquired current assets and total assets of $92.9 million and $433.9 million, respectively, and assumed current liabilities and total liabilities of $52.9 million and $124.4 million, respectively. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for more information.

The year ended December 31, 2012 was impacted by a favorable tax benefit of a net $7.3 million from removing valuation allowances on deferred tax assets in the U.S. Additionally, results for the year ended December 31, 2012 were negatively impacted by impairments of $1.0 million and after tax foreign exchange losses of $1.1 million related to intercompany notes.

The year ended December 31, 2011 was impacted by certain items including $5.0 million in additional start-up costs from new multi-year sales programs (all in our Precision Engineered Products Group, formerly known as our Plastics and Rubber Group) and $0.8 million in a one-time tax benefit from removing valuation allowances on certain deferred tax assets in Europe.

The following discussion should be read in conjunction with, and is qualified in its entirety by, the Consolidated Financial Statements and the Notes thereto and Selected Financial Data included elsewhere in this Annual Report on Form 10-K. Historical operating results and percentage relationships among any amounts included in the Consolidated Financial Statements are not necessarily indicative of trends in operating results for any future period. Unless otherwise noted herein, all amounts are in thousands, except per share numbers.

Our significant accounting policies, including the assumptions and judgment underlying them, are disclosed in Note 1 of the Notes to Consolidated Financial Statements. These policies have been consistently applied in all material respects and address such matters as revenue recognition, inventory valuation and asset impairment recognition. Due to the estimation processes involved, management considers the following summarized accounting policies and their application to be critical to understanding our business operations, financial condition and results of operations. We cannot assure you that actual results will not significantly differ from the estimates used in these critical accounting policies.

Business Combinations. We allocate the total purchase price of the acquired tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the business combination date, with the excess purchase price recorded as goodwill. The purchase price allocation process required us to use significant estimates and assumptions, including fair value estimates, as of the business combination date. Although we believe the assumptions and estimates we have made are reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired company, in part based on valuation models that incorporate projections of expected future cash flows and operating plans and are inherently uncertain. Valuations are performed by management or third party valuation specialists under management’s supervision. In determining the fair value of assets acquired and liabilities assumed in business combinations, as appropriate, we may use one of the following recognized valuation methods: the income approach (including discounted cash flows from relief from royalty and excess earnings model), the market approach and/or the replacement cost approach.

Examples of significant estimates used to value certain intangible assets acquired include but are not limited to:

However, different assumptions regarding projected performance and other factors associated with the acquired assets may affect the amount recorded under each type of assets and liabilities, mainly between property plant and equipment, intangibles assets, goodwill and deferred income tax liabilities and subsequent assessment could result in future impairment charges. The purchase price allocation process also entails us to refine these estimates over a measurement period not to exceed one year to reflect new information obtained surrounding facts and circumstances existing at acquisition date.

Goodwill and Acquired Intangibles. For new acquisitions, we use estimates, assumptions and appraisals to allocate the purchase price to the assets acquired and to determine the amount of goodwill. These estimates are based on market analyses and comparisons to similar assets. Annual procedures are required to be performed to assess whether recorded goodwill is impaired. The annual tests require management to make estimates and assumptions with regard to the future operations of its reporting units, and the expected cash flows that they will generate. These estimates and assumptions could impact the recorded value of assets acquired in a business combination, including goodwill, and whether or not there is any subsequent impairment of the recorded goodwill and the amount of such impairment.

Goodwill is tested for impairment on an annual basis as of October 1 and between annual tests if a triggering event occurs. The impairment procedures are performed at the reporting unit level. In testing goodwill, we have the option to first assess qualitative factors to determine whether it is necessary to perform a two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount including goodwill, the quantitative impairment test is required. Otherwise, no further testing is required. The decision to perform a qualitative assessment or perform a complete step 1 analysis is an annual decision made by management based on several factors including budget to actual performance, economic, market and industry considerations such as automotive production rates in the geographic markets we serve and cash flow from operations.

Generally accepted accounting principles in the U.S. (“GAAP”) prescribes a quantitative two-step process of testing for goodwill impairments. The first step is to determine if the carrying value of the reporting unit with goodwill is less than the related fair value of the reporting unit. We considered three main approaches to value (cost, market and income) the fair value of the reporting unit and market based multiples of earning and sales methods obtained from a grouping of comparable publicly trading companies. We believe this methodology of valuation is consistent with how market participants would value reporting units. The discount rate and market based multiples used are specifically developed for the units tested regarding the level of risk and end markets served. Even though we do use other observable inputs (Level 2 inputs under the GAAP hierarchy) the calculation of fair value for goodwill would be most consistent with Level 3 under the GAAP hierarchy. We conducted tests for goodwill impairment for years end 2015 and 2014 and concluded no impairment of goodwill had occurred. The PEP Acquisition was not part of 2015 testing of goodwill.

If the carrying value of the reporting unit, including goodwill, is less than fair value of the reporting unit, the goodwill is not considered impaired. If the carrying value is greater than fair value then the potential for impairment of goodwill exists. The potential impairment is determined by allocating the fair value of the reporting unit among the assets and liabilities based on a purchase price allocation methodology as if the reporting unit was acquired in a business combination. The fair value of the goodwill is implied from this allocation and compared to the carrying value with an impairment loss recognized if the carrying value is greater than the implied fair value.

Our indefinite lived intangible asset is accounted for similarly to goodwill. This asset is tested for impairment at least annually by comparing the fair value to the carrying value, using the relief from royalty rate method, and if the fair value is less than the carrying value, an impairment charge is recognized for the difference. The indefinite lived intangible asset was impaired during the year ended December 31, 2014, as management is in the process of phasing out the use of the trade name as a result of the Autocam acquisition.

Income taxes. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The calculation of tax assets, liabilities, and expenses under GAAP is largely dependent on management judgment of the current and future deductibility and utilization of taxable expenses and benefits using a more likely than not threshold. Specifically, the realization of deferred tax assets and the certainty of tax positions taken are largely dependent upon management weighting the current positive and negative evidence for recording tax benefits and expenses. Additionally, many of our positions are based on future estimates of taxable income and deductibility of tax positions. Particularly, our assertion of permanent reinvestment of foreign undistributed earnings is largely based on management’s future estimates of domestic and foreign cash flows and current strategic foreign investment plans. In the event that the actual outcome from future tax consequences differs from management estimates and assumptions or management plans and positions are amended, the resulting change to the provision for income taxes could have a material impact on the consolidated results of operations and statement of financial position. (See Notes 1 and 13 of the Notes to Consolidated Financial Statements).

We did not record a U.S. deferred tax liability for the excess of the book basis over the tax basis of our investments in foreign subsidiaries to the extent the foreign earnings meet the indefinite reversal criteria. As of the year ended December 31, 2015, we consider the unremitted foreign earnings of our foreign subsidiaries to be reinvested indefinitely. We base this assertion on two factors. First, our intention to invest in foreign countries that are strategically important to our Precision Bearing Components Group and our Autocam Precision Components Group and our customers. With the acquisitions completed in 2015, we have expanded our domestic and international base of operations adding subsidiaries in Mexico and China, which will require more foreign investment. Second, we have sufficient access to funds in the U.S. through projected free cash flows and the availability of our credit facilities to fund currently anticipated domestic operational and investment needs. As such, we do not expect unrepatriated foreign earnings to become subject to U.S. taxation.

Impairment of Long-Lived Assets. Our long-lived assets include property, plant and equipment. The recoverability of the long-term assets is dependent on the performance of the companies which we have acquired or built, as well as the performance of the markets in which these companies operate. In assessing potential impairment for these assets, we will consider these factors as well as forecasted financial performance based, in large part, on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Future adverse changes in market conditions or adverse operating results of the underlying assets could result in having to record additional impairment charges not previously recognized.

Results of Operations

During the year ended December 31, 2014, we completed the acquisition of four companies: V-S, RFK, Chelsea and Autocam. The acquisitions of V-S, RFK, Chelsea and Autocam occurred on January 20, 2014, June 20, 2014, July 15, 2014 and August 29, 2014, respectively. As such only eleven, six, five, and four months of operations were included in the year ended December 31, 2014 with respect to V-S, RFK, Chelsea and Autocam, respectively. During the year ended December 31, 2015, we completed the acquisition of two companies: Caprock and PEP. We acquired Caprock on May 29, 2015 and PEP on October 19, 2015. As such seven and two months of operations were included in the year ended December 31, 2015 with respect to Caprock and PEP. In an effort to enhance the comparability of the current and prior year periods, we have aggregated into “acquisitions” within each financial line item comparison for the years ended December 31, 2015 and 2014 that were not included in the comparative prior year period. The remaining changes related to our legacy business.

Devaluation of the Euro against the U.S. Dollar

The euro devalued against the U.S. dollar beginning in the latter part of the third quarter of 2014 and accelerated during the fourth quarter of 2014 and into the first quarter of 2015. During these periods, the euro to U.S. dollar dropped from approximately $1.36 in June 2014 to $1.08 in March 2015, representing an approximate 20% decline in value. The exchange rate ranged between $1.08 and $1.12 for the remainder of the year. The devaluation of the euro significantly impacted the translation of our euro denominated sales and costs when comparing year over year activity. The euro translation impact, and the translation impact of other currencies, is highlighted below in the overall results as “foreign exchange effects”. In addition to translation effects, the devaluation of the euro impacted the value of certain intercompany loan receivables denominated in euros that resulted in an unfavourable transactional impact.

As a Percentage of Net Sales

For the Year Ended December 31,

Sales Concentration

Sales to various U.S. and foreign divisions of SKF, one of the largest bearing manufacturers in the world, accounted for approximately 16% of consolidated net sales in 2015. During 2015, sales to various U.S. and foreign divisions of our ten largest customers accounted for approximately 53% of our consolidated net sales. None of our other customers individually accounted for more than 10% of our consolidated net sales for 2015. The loss of all or a substantial portion of sales to these customers would cause us to lose a substantial portion of our revenue and have a corresponding negative impact on our operating profit margin due to the operational leverage these customers provide. This could lead to sales volumes not being high enough to cover our current cost structure or to provide adequate operating cash flows or cause us to incur additional restructuring and/or impairment costs. Due to a limit on the amount of excess bearing component production capacity in the markets we serve, we believe it would be difficult for any of our top ten customers to take a significant portion of our business away in the short term.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014.

The year ended December 31, 2015, was significantly impacted by certain costs related to the PEP Acquisition and to a lesser extent one other acquisition completed in 2015. The net after tax impact of these costs was $43.2 million. The following is a summary of these costs:

OVERALL RESULTS

Net Sales Net sales increased during 2015 compared to 2014 principally due to sales from the companies acquired in 2014 and 2015. Three of the four companies acquired during 2014 were acquired subsequent to the first half of 2014 and two were acquired during 2015. Additionally, sales growth came from overall volume growth in the markets we serve, from new sales programs with existing customers and sales with new customers in each of these geographic markets. Partially offsetting these increases was the impact of devaluation of the euro on euro denominated sales, as discussed above.

Cost of Products Sold (exclusive of depreciation and amortization shown separately below). Cost of products sold was primarily impacted by the addition of production costs added with the 2015 and 2014 acquisitions, as discussed above. Additionally, the total was impacted by increased production costs at those units that experienced higher sales volumes, as discussed above. Finally, we incurred $7.5 million of costs directly related to acquisitions and integrations specifically $4.3 million related to a step-up in value of inventory of an acquired company and $3.3 million related to integration costs. Partially offsetting these increases was the impact of devaluation of the euro on euro denominated costs, as discussed above.

29

Table of Contents

Selling, General and Administrative. The majority of the increase during 2015 was due to the selling, general and administrative costs carried over from the companies acquired in 2015 and 2014.

Acquisition related costs excluded from selling, general and administrative. Acquisition related costs are third party legal, accounting, valuation consulting and investment banking advisory fees incurred directly related to the PEP Acquisition and the Caprock acquisition in 2015, and Autocam acquisition and our other acquisitions in 2014.

Depreciation and Amortization. The increase in 2015 was due to depreciation and amortization from the 2015 and 2014 acquisitions. The additional depreciation and amortization includes the related step-ups of certain property, plant and equipment to fair value and the addition of intangible assets principally for customer relationships and trade names related to the purchase price allocation of the new acquisitions.

Interest expense. Interest expense increased in 2015 from the interest on the debt we undertook to complete our acquisitions. Additionally, 2015 included a $5.2 million charge related to amortizing a large portion of a backlog intangible asset acquired in 2015.

Write-off of unamortized debt issuance costs. Write-off of debt issuance costs increased due to the refinancing of acquisitions in both 2015 and 2014.

Provision for Income Taxes. The 2015 effective tax rate of 46% is consistent with the 2014 effective rate of 44%. Both rates are impacted by non-deductible mergers and acquisition cost.

RESULTS BY SEGMENT

PRECISION BEARING COMPONENTS GROUP

Net sales decreased from 2014 to 2015 principally due to the impact of devaluation of the euro on euro denominated sales, as discussed above. Partially offsetting, the unfavorable foreign exchange effects was greater demand for our products in the North American, Asian and European automotive and general industrial markets. This greater demand was from market share gains with our customers and from winning business with new customers. Additionally, sales increased with the addition of the companies the segment acquired subsequent to the first half of 2014.

Segment income from operations was unfavorably impacted by $3.3 million due to the depreciation in value of Euro denominated income from operations relative to the U.S. Dollar. Additionally, the segment incurred $1.8 million in restructuring costs related to reduce headcount at certain European plants.

PRECISION ENGINEERED PRODUCTS GROUP

The Precision Engineered Products Group includes the Plastic and Rubber Components Segment as presented in previous filings. The name of this segment was changed during 2015 after the PEP Acquisition and disposal of Delta Rubber. The increase in sales was primarily due to the acquisition of Caprock during the second quarter of 2015 and the PEP Acquisition in the fourth quarter of 2015. Loss from operations was primarily due to increased depreciation and amortization related to the PEP Acquisition. Specifically included in income from operations was $4.3 million related to a step-up in value of inventory of an acquired company, a charge of $5.2 million related to amortizing a large portion of a backlog intangible asset of an acquired company and $1.6 million of acquisition and integration costs directly attributable to acquisitions within the segment.

Table of Contents

AUTOCAM PRECISION COMPONENTS GROUP

The increased sales from 2014 to 2015 were due to sales added with the acquisition during 2014. The increase in income from operations was primarily from the companies acquired in 2014 partially offset by $2.6 million in restructuring costs related to the Wheeling Plant closure.

Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013.

The year ended December 31, 2014, was significantly impacted by certain costs related to the Autocam acquisition and to a lesser extent the three other acquisitions completed in 2014. The net after tax impact of these costs was $13.6 million. The following is a summary of these costs:

31

Table of Contents

OVERALL RESULTS

Net Sales. Net sales increased during 2014 compared to 2013 principally due to sales from the four companies acquired in 2014. Net sales reported for 2014 includes four month of Autocam, six months of RFK, five months of Chelsea, and 11 months of V-S. Additionally, net sales increased due to greater demand for our products in the European, North American and Asian automotive markets. The growth with our customers over the prior year was generally consistent with the overall growth in automotive production in those geographic regions. Additionally, we have continued to benefit from improved market share with certain customers and adjacent market expansion.

The reduction in price and raw material pass-through (in 2014 compared to 2013) was driven mainly by lower levels of material inflation in our businesses which led to lower pass-through to our customers and due to contractual price decreases for certain long-term sales programs. The unfavorable sales impact related to mix was due to experiencing higher volumes of certain products that have lower prices than our average product assortment sold during the comparable period. The majority of the unfavorable mix occurred in the first six months of 2014.

Cost of Products Sold (exclusive of depreciation and amortization shown separately below). Cost of products sold was primarily impacted by the addition of production costs added with the four companies acquired in 2014 as discussed above. Additionally, we experienced increased production costs at those units with higher sales volumes, as discussed above. Partially offsetting the increase in cost of products sold were benefits from specific continuous improvement projects undertaken subsequent to 2013.

Selling, General and Administrative. The majority of the increase was due to the selling, general and administrative costs brought over from the four companies acquired in 2014. Additionally, spending has increased as we have invested in certain key functional positions and research and development costs related to the execution of our strategic plans for growth.

Acquisition related costs excluded from selling, general and administrative. Acquisition related costs are third party legal, accounting, valuation consulting and investment banking advisory fees incurred directly related to the Autocam acquisition and the three other acquisitions in 2014 to a lesser extent.

Depreciation and Amortization. The increase in depreciation and amortization was due to adding depreciation and amortization from the four acquisitions closed during 2014 including the related step-ups of certain property, plant and equipment to fair value and the addition of intangible assets related to the purchase price allocation.

Interest expense. Interest expense increased $3.0 million in 2014 compared to 2013 due to the acquisition related expenses from writing off debt issuance costs and make whole interest payments related to our former credit facilities as part of the Autocam acquisition. Additionally, interest on our $350.0 million term loan entered into to complete the Autocam acquisition amounted to an additional $6.7 million in interest including the amortization of debt issuance costs.

Table of Contents

Provision for Income Taxes. The 2014 effective tax rate of 44% reflects the impact of two items related to the merger and acquisition activity in 2014 including (1) $2.0 million for non-deductible third party merger and acquisition as these cost were directly facilitative to the acquisitions; and (2) $1.3 million for the expiration of foreign tax credits that could not be utilized during 2014 because of the merger related acquisition costs. In addition, the rate reflects an offset to the items above for the impact of foreign earnings taxed at lower rates of $1.7 million.

RESULTS BY SEGMENT

PRECISION BEARING COMPONENTS GROUP

Net sales increased during 2014 compared to 2013 principally due to increased sales volumes resulting from greater demand for our products in the European, North American and Asian automotive markets and from better overall market penetration with our customers. The reduction in price and raw material pass-through was driven mainly by lower levels of material inflation in our businesses which led to lower pass-through to our customers. The unfavorable sales impact related to mix was due to certain products sold during 2014 being lower priced than our average product assortment sold during 2013. Finally, the segment benefited from the additional sales RFK (for six months) and Chelsea (for five months), each of which was acquired in 2014.

Increased sales volumes in 2014 compared to 2013 added $5.3 million in incremental income from operations and the acquisition of RFK and Chelsea added $0.2 million in income from operations. Additionally, continuous improvement projects added $4.3 million to income from operations. Partially offsetting these increases were the unfavorable impacts of price/mix of $3.9 million and inflation of $1.5 million.

PRECISION ENGINEERED PRODUCTS GROUP

The Precision Engineered Products Group includes the Plastic and Rubber Components Segment as presented in previous filings. The name of this segment was changed during 2015 after the PEP Acquisition and disposal of Delta Rubber. Sales decreased due to lower volume from certain sales programs ending. Segment income from operations was up $0.6 million due to benefits from continuous improvement projects had a favorable $1.3 million impact on income from operations more than offsetting the unfavorable volume effects.

33

Table of Contents

AUTOCAM PRECISION COMPONENTS GROUP

The increased sales during 2014 compared to 2013 were due to sales added with the acquisitions of Autocam (four months of sales) and V-S (eleven months of sales). Additionally, sales increased due to greater demand with certain customers in the North American automotive market generally in line with the overall growth in automotive production and greater demand with our HVAC customer.

The main driver of the increased segment income from operations was income from operations of the two acquired companies which added $3.6 million. The segment income from operations was further impacted by $2.5 million in incremental income from increased sales volumes and $2.3 million in income from continuous improvement projects and operational improvement. Partially offsetting these increases were the unfavorable impacts of price/mix of $1.6 million.

Changes in Financial Condition from December 31, 2014 to December 31, 2015.

From December 31, 2014 to December 31, 2015, our total assets increased by $680.8 million and our current assets increased by $37.4 million. The majority of these increases were due to total assets and current assets acquired of $741.6 million and $71.2 million, respectively, and the related preliminary fair value step-ups for the two acquisitions completed in 2015. Foreign exchange translation impacted the balance sheet in comparing changes in account balances from December 31, 2014 to December 31, 2015 by decreasing total assets $35.7 million and current assets $12.5 million.

Beyond acquisition and foreign exchange effects, the accounts receivable balance at December 31, 2015, was higher due to increased sales volume experienced in 2015 compared with sales levels in 2014. Our inventory balance increased $28.4 million due primarily to the PEP Acquisition. Additionally, other non-current assets increased by $5.4 million due to debt issuance cost incurred related to our new credit facilities entered into concurrent with the PEP Acquisition, net of amortization.

From December 31, 2014 to December 31, 2015, our total liabilities increased $540.6 million. The majority of the increase was from the $469.9 million increase in long-term debt and current maturities of long-term debt primarily due to the two acquisitions in 2015 and $111.3 million of liabilities assumed related to the two acquisitions completed in 2015.

Working capital, which consists principally of accounts receivable and inventories offset by accounts payable and current maturities of long-term debt, was $146.8 million at December 31, 2015 as compared to $105.2 million at December 31, 2014. The increase in working capital was due primarily to acquiring $49.5 million in net working capital in the two acquisitions completed in 2015. The remainder of the increase was due primarily to the increase in accounts receivable and inventory discussed above.

Cash provided by operations was $33.3 million in 2015 compared with cash provided by operations of $30.7 million in 2014. The difference was increased results of operations, offset by higher interest costs incurred servicing the debt for the acquisitions. Cash flow provided by operations was $30.7 million for 2014 compared with $31.7 million for 2013. The difference was better working capital management in 2014.

Cash used by investing activities was $665.8 million in 2015 compared with cash used by investing activities of $281.6 million in 2014. The difference was primarily due to the $628.2 million in cash paid to acquire PEP and Caprock, net of cash received. Cash used by investing activities was $281.6 million in 2014 compared with cash used by investing activities of $15.2 million in 2013. The difference was primarily due to the $257.7 million in cash paid to acquire Autocam, V-S, Chelsea and RFK, net of cash received.

34

Table of Contents

Cash provided by financing activities was $611.9 million in 2015, compared with cash used by financing activities of $287.0 million in 2014. The difference was primarily related to using debt to fund the PEP Acquisition and the offering of our common stock. Cash used by financing activities was $287.0 million for 2014 compared with cash used by financing activities of $32.2 million in 2013. The difference was primarily related to using debt to fund the acquisitions of Autocam, V-S, Chelsea and RFK.

Liquidity and Capital Resources

On July 1, 2015, we closed an underwritten registered public offering of common stock offered pursuant to a shelf registration statement on Form S-3 that was previously filed with, and declared effective by, the Securities Exchange Commission (the “SEC” or “Commission”). The total number of share of common stock sold was approximately 7.6 million at a public offering price of $24.00 per share. All of the shares in the offering were sold by us. The net proceeds to us from the offering, after deducting underwriting discounts and commissions and offering expenses, were approximately $173.1 million. Of these proceeds, $148.7 million was used for repayment of principal and interest on our debt.

On October 19, 2015, concurrent with the PEP Acquisition, we: (i) entered into the New Term Loan Credit Facility; (ii) entered into the New Senior Secured Revolving Credit Facility; and (iii) issued $300.0 million of the Senior Notes. Proceeds from the New Term Loan Credit Facility and the Senior Notes were used to finance the purchase price of the PEP Acquisition and pay down debt. The New Senior Credit Facilities replaced our existing credit facilities. On November 9, 2015, an incremental term loan of $50.0 million was drawn on the New Term Loan Credit Facility and the proceeds were used to repurchase approximately $50.0 million of the Senior Notes. During the year ended December 31, 2015, we were not subject to debt covenants.

Our New Term Loan Credit Facility requires us to pay quarterly 0.25% of the initial principal amount over the next seven years with the remaining principal amount due on the maturity date. Additionally, as long as LIBOR stays below 1.00%, we will be paying 5.75% per annum in interest. If the LIBOR exceeds 1.00%, then the rate will be the variable LIBOR rate plus an applicable margin of 4.75%. We believe that funds generated from our consolidated operations will provide sufficient cash flow to service these required debt payments.

Our arrangements with our domestic customers typically provide that payments are due within 30 to 60 days following the date of our shipment of goods, while arrangements with foreign customers of our domestic business (other than foreign customers that have entered into an inventory management program with us) generally provide that payments are due within 60 to 120 days following the date of shipment to allow for additional transit time and customs clearance. Under the Metal Bearing Components Group’s inventory management program with certain customers, payments typically are due within 30 days after the customer uses the product. Our arrangements with European customers regarding due dates vary from 30 to 90 days following date of sale for European based customers and 60 to 120 days from customers outside of Europe to allow for additional transit time and customs clearance. Our sales and receivables can be influenced by seasonality due to our relative percentage of European business coupled with many foreign customers slowing production during the month of August. For information concerning our quarterly results of operations for the years ended December 31, 2015 and 2014, see Note 17 of the Notes to Consolidated Financial Statements.

We invoice and receive payment from many of our customers in euros as well as other currencies. Additionally, we are party to various third party and intercompany loans, payables and receivables denominated in currencies other than the U.S. dollar. As a result of these sales, loans, payables and receivables, our foreign exchange transaction and translation risk has increased. Various strategies to manage this risk are available to management including producing and selling in local currencies and hedging programs. As of December 31, 2015, no currency hedges were in place. In addition, a strengthening of the U.S. dollar and/or euro against foreign currencies could impair our ability to compete with international competitors for foreign as well as domestic sales.

During 2015, we expect to spend approximately $40 to $50 million on capital expenditures, the majority of which relate to new or expanded business. We believe that funds generated from operations and borrowings from the credit facilities will be sufficient to finance our capital expenditures and working capital needs through December 2015. We base this assertion on our current availability for borrowing of up to $90.9 million and our forecasted positive cash flow from operations for the year ending December 31, 2015.

Table of Contents

The table below sets forth our contractual obligations and commercial commitments as of December 31, 2015 (in thousands):

There are $6.1 million of long-term post-employment benefits, the payment of which depends on various factors including the date of the employee’s termination. Based on the best available information, we believe the vast majority of these payments will be made after 5 years.

We have approximately $5.7 million in unrecognized tax benefits and related penalties and interest accrued within the liabilities section of our balance sheet. We are unsure when or if at all these amounts might be paid to U.S. and/or foreign taxing authorities. Accordingly, these amounts have been excluded from the table above. (See Note 13 of the Notes to the Consolidated Financial Statements).

Functional Currencies

We currently have operations in Slovakia, Italy, Netherlands and France, all of which are euro participating countries. Each of our European facilities sell product to customers in many of the euro participating countries. The euro has been adopted as the functional currency at all of our locations in Europe. The functional currency of both NN Asia and Autocam Asia are the Chinese yuan and Autocam, Poland is the zloty.

Seasonality and Fluctuation in Quarterly Results

Our net sales historically have been seasonal in nature, due to a significant portion of our sales being to European customers who significantly slow production during the month of August. For information concerning our quarterly results of operations for the years ended December 31, 2015 and 2014, see Note 17 of the Notes to the Consolidated Financial Statements.

Off-Balance Sheet Arrangements

We are not a party to any off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Inflation and Changes in Prices

The cost base of our operations has been materially affected by steel inflation during recent years. Due to the ability to pass on this steel inflation to our customers the overall financial impact has been minimized. The prices for steel, engineered resins and other raw materials which we purchase are subject to material change. Our typical pricing arrangements with steel suppliers are subject to adjustment every three to six months in the U.S. and annually in Europe for base prices but quarterly for scrap surcharge adjustments. In the past, we have been able to minimize the impact on our operations resulting from the steel price fluctuations by adjusting selling prices to our customers periodically in the event of changes in our raw material costs.

We are exposed to changes in financial market conditions in the normal course of our business due to our outstanding debt balances as well as from transacting in various foreign currencies. To mitigate our exposure to these market risks, we have established policies, procedures and internal processes governing our management of financial market risks. We are exposed to changes in interest rates primarily as a result of our borrowing activities. At December 31, 2015, we had $569.0 million outstanding under the variable rate credit facilities and $244.5 million outstanding under the fixed rate 10.25% Senior Notes. At December 31, 2015, a one-percent increase in the interest rate charged on our outstanding variable rate borrowings would result in interest expense increasing annually by approximately $5.6 million.

Our policy is to manage interest expense using a mix of fixed and variable rate debt. As such, we entered into a $150.0 million interest rate swap on December 16, 2014 that went into effect on December 29, 2015 and will fix our interest rate at 6.966%. The nature and amount of our borrowings may vary as a result of future business requirements, market conditions and other factors.

Translation of our operating cash flows denominated in foreign currencies is impacted by changes in foreign exchange rates. Our Precision Bearing Components Group invoices and receives payment in currencies other than the U.S. dollar including the euro. Additionally, we participate in various third party and intercompany loans, payables and receivables denominated in currencies other than the U.S. dollar. To help reduce exposure to foreign currency fluctuation, we have incurred debt in euros in the past and have, from time to time, used foreign currency hedges to hedge currency exposures when these exposures meet certain discretionary levels. We did not use any currency hedges in 2015, nor did we hold a position in any foreign currency hedging instruments as of December 31, 2015.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of NN, Inc.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income and comprehensive income (loss), of changes in stockholder’s equity and of cash flows present fairly, in all material respects, the financial position of NN, Inc. and its subsidiaries at December 31, 2015 and December 31, 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under item 9A. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded Precision Engineered Products (“PEP”) and Caprock Manufacturing, Inc. and Caprock Enclosures, LLC (collectively referred to as “Caprock”) from its assessment of internal control over financial reporting as of December 31, 2015 as they were acquired by the Company in purchase business combinations during 2015. We have also excluded PEP and Caprock from our audit of internal control over financial reporting. PEP and Caprock are wholly-owned subsidiaries, whose total assets and total revenues represent approximately 9% and 7% (Caprock is less than 1% of each metric), respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2015.
