Notes to Condensed Consolidated Financial Statements

June 30, 2015 and 2014

(In thousands, except per share data)

The accompanying condensed consolidated financial statements of NN, Inc. have not been audited, except that the condensed consolidated balance sheet at December 31, 2014 was derived from our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014, which was filed with the U.S. Securities and Exchange Commission, or SEC, on March 16, 2015. In our opinion, these financial statements reflect all adjustments necessary to fairly state the results of operations for the three and six month periods ended June 30, 2015 and 2014, our financial position at June 30, 2015 and December 31, 2014, and the cash flows for the six month periods ended June 30, 2015 and 2014 on a basis consistent with our audited financial statements. These adjustments are of a normal recurring nature and are, in the opinion of management, necessary for fair statement of the financial position and operating results for the interim periods. As used in this Quarterly Report on Form 10-Q, the terms “NN”, “the Company”, “we”, “our”, or “us” mean NN, Inc. and its subsidiaries.

Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted from the interim financial statements presented in this Quarterly Report on Form 10-Q. These unaudited, condensed and consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our most recent Annual Report on Form 10-K for the year ended December 31, 2014, which we filed with the SEC on March 16, 2015. The results for the three and six month periods ended June 30, 2015 are not necessarily indicative of results for the year ending December 31, 2015 or any other future periods.

On May 29, 2015, NN completed the acquisition of Caprock Manufacturing, Inc. and Caprock Enclosures, LLC (collectively referred to as “Caprock”) for approximately $9,000 in cash. Caprock was a privately held plastic components supplier located in Lubbock, TX. Caprock serves multiple end markets including aerospace, medical and general industrial. The acquisition provides further balancing of our end markets and represents the first step in our focused plan toward transforming our plastics business. The results of Caprock have been consolidated with NN since the date of acquisition as part of the Plastic and Rubber Components Segment. We are in the process of finalizing fair market valuations of all the net assets acquired given the purchase was made close to the end of the quarter. The preliminary purchase price allocation includes $1,452 in net working capital, $2,960 in property plant and equipment, $2,490 in intangible assets, and $2,099 in goodwill, which we expect to be fully deductible for tax purposes. The goodwill is attributable to expected cost synergies and revenue growth plus the assembled work force.

On June 20, 2014, we acquired 79.2% of the outstanding shares of RFK Valjcici d. d. Konjic (“RFK”) for $9,756 in cash. RFK is a manufacturer of tapered rollers with operations in Konjic, Bosnia & Herzegovina. As of June 30, 2014, we reported a non-controlling interest of $2,559 for RFK representing the fair value of the 20.8% of the shares outstanding we did not own. NN purchased up to 99.7% of the shares of RFK in the second half of 2014 for $2,528 in cash and reclassified this amount from a non-controlling interest. RFK’s products, while complementary to NN’s existing roller bearing components, broadened our product offering and allowed penetration into adjacent markets. The results of the operations of RFK have been consolidated with NN since the date of acquisition as a part of the Metal Bearing Components Segment.

On January 30, 2014, we purchased the majority of the operating assets of V-S Industries, V-S Precision, LLC and V-S Precision SA de DV (collectively referred to as “VS”) from the secured creditors of V-S Industries for $5,580 in cash and assumed certain liabilities totaling $2,968. This was accounted for as a business combination. VS is a precision metal components manufacturer that supplies customers in a variety of industries including electric motors, HVAC, power tools, automotive and medical. The acquisition of VS provided us with a complementary, broader product offering and allowed penetration into adjacent markets. VS has two locations in Wheeling, Illinois and Juarez, Mexico and is included in Autocam Precision Components Segment.

Inventories are comprised of the following:

Inventories on consignment at customer locations as of June 30, 2015 and December 31, 2014 totaled $4,981 and $5,857, respectively.

Inventories are stated at the lower of cost or market. Cost is determined using the average cost method. The inventory valuations above were developed using normalized production capacities for each of our manufacturing locations. Any costs from abnormal excess capacity or under-utilization of fixed production overheads are expensed in the period incurred and are not included as a component of inventory valuation.

There were no anti-dilutive options excluded from the dilutive shares outstanding for the three and six month periods ended June 30, 2015 and 2014.

The segment information and the accounting policies of each segment are the same as those described in the notes to the consolidated financial statements entitled “Segment Information” and “Summary of Significant Accounting Policies and Practices,” respectively, included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, which we filed with the SEC on March 16, 2015. Autocam Corporation (“Autocam”) was added to the Precision Metal Components segment during the third quarter of 2014 and the segment was renamed the Autocam Precision Components Segment during the fourth quarter of 2014. We account for inter-segment sales and transfers at current market prices. We did not have any significant inter-segment transactions during the three and six month periods ended June 30, 2015 and 2014.

Long-term debt and short-term debt at June 30, 2015 and December 31, 2014 consisted of the following:

Our $350,000 term loan facility may be expanded upon our request with approval of the lenders by up to $50,000 under the same terms and conditions. The term loan has a seven year maturity with a 5% per annum repayment. The term loan agreement is a covenant lite agreement with no financial covenants. The term loan agreement does contain customary restrictions on, among other things, additional indebtedness, liens on our assets, sales or transfers of assets, investments, issuance of equity securities, and mergers, acquisitions and other fundamental changes in our business including a “material adverse change” clause, which if triggered would give the lenders the right to accelerate the maturity of the debt. Costs associated with entering into the revolving credit facility were capitalized and will be amortized into interest expense over the life of the facility. As of June 30, 2015, $8,434 of net capitalized loan origination costs related to the term loan are reflected in the condensed consolidated balance sheet within other non-current assets.

Our $100,000 asset backed loan, or ABL, may be expanded upon our request with approval of the lenders by up to $50,000 under the same terms and conditions. The ABL has a five year maturity and has one springing financial covenant in the event our availability on the ABL is less than $8,000. The ABL contains customary restrictions on, among other things, additional indebtedness, liens on our assets, sales or transfers of assets, investments, issuance of equity securities, and mergers, acquisitions and other fundamental changes in our business including a “material adverse change” clause, which if triggered would give the lenders the right to accelerate the maturity of the debt. The facility has a swing line feature to meet short term cash flow needs. Any borrowings under this swing line are considered short term. We incurred costs as a result of issuing the ABL, which have been recorded in the condensed consolidated balance sheet within other non-current assets and are being amortized over the term of the notes. The unamortized balance at June 30, 2015 was $1,158.

We believe the book values of the above credit facilities approximate their fair values given the interest rates are variable and are consistent with market rates for a company with our credit profile.

Our French operation (acquired with Autocam) has liabilities with certain creditors subject to Safeguard protection. The liabilities are being paid annually over a 10-year period until 2019 and carry a zero percent interest rate. Amounts due as of June 30, 2015, to those creditors opting to be paid over a 10-year period totaled $2,362 and are included in current maturities of long-term debt of $304 and long-term debt, net of current portion of $2,058.

The Brazilian lines of credit include facilities with certain Brazilian banks used to fund working capital needs, while the equipment notes represent borrowings from certain Brazilian banks to fund equipment purchases for Autocam’s Brazilian plants. These credit facilities have annual interest rates ranging from 2.5% to 22.4%.

The Chinese line of credit is a working capital line of credit with a Chinese bank bearing an annual interest rate of 4.95%.

The changes in the carrying amount of goodwill, net for the six month period ended June 30, 2015 are as follows:

The goodwill balances are tested for impairment on an annual basis during the fourth quarter and between annual tests if a triggering event occurs. As of June 30, 2015, there were no indications of impairment at the reporting units with goodwill balances.

With the Caprock acquisition, we acquired intangible assets with a preliminary aggregate acquired value of $2,490. The intangible assets are a customer relationship intangible asset with a preliminary estimated value of $2,430 and a trade name intangible asset with a preliminary estimated value of $60. The preliminary estimated useful lives of the intangibles are 12 years and one year, respectively. These intangible assets are subject to amortization of approximately $203 per year with year- to-date amortization expense and accumulated amortization of $22 at June 30, 2015.

Including the intangibles from the Caprock acquisition, we have gross intangible assets of $57,226 with accumulated amortization of 4,297, year to date amortization expense of $2,013 and annual expected amortization expense of $4,090.

During the three and six month periods ended June 30, 2015 and 2014, approximately $988 and $1,771 in 2015 and $714 and $1,286 in 2014, respectively, of compensation expense was recognized in selling, general and administrative expense for all share-based awards. During the six month period ended June 30, 2015, there were 115 restricted stock awards and 55 option awards to non-executive directors, officers and certain other key employees. Additionally, during the six months ended June 30, 2015, there were 70 performance stock units issued. During the six month period ended June 30, 2014, there were 97 restricted stock awards and 98 option awards to non-executive directors, officers and certain other key employees.

The restricted shares granted during the six month period ended June 30, 2015, vest pro-rata over three years for officers and certain other key employees and over one year for non-executive directors. The restricted shares granted during the six month period ended June 30, 2014, vest pro-rata over three years. During the six month periods ended June 30, 2015 and 2014, we incurred $1,079 and $575, respectively, in expense related to restricted stock. The fair value of the shares issued was determined by using the grant date closing price of our common stock.

The performance stock units granted during the six month period ended June 30, 2015, will be satisfied in the form of company stock during 2018 depending on meeting certain performance and/or market conditions. We are recognizing the compensation expense over the three year period in which the performance and market conditions are measured. During the six month periods ended June 30, 2015 and 2014, we incurred $182 and $0, respectively, in expense related to performance stock units. The fair value of the shares issued was determined by using the grant date closing price of our common stock for the units with a performance condition and a Monte Carlo valuation model was used to determine the fair value for shares that have a market condition.

We incurred $510 and $711 of stock option expense in the six month periods ended June 30, 2015 and 2014, respectively. The fair value of our options cannot be determined by market value, because our options are not traded in an open market. Accordingly, we utilized the Black Scholes financial pricing model to estimate the fair value.

The following table provides a reconciliation of option activity for the six month period ended June 30, 2015:

For the six month periods ended June 30, 2015 and 2014, our effective tax rates were 22% and 32%, respectively. The difference between the U.S. federal statutory tax rate of 34% and our effective tax rates was due to non-U.S. based earnings being taxed at lower rates reducing the effective rates for the six month periods ended June 30, 2015 and 2014, by 8% and 2%, respectively. As of June 30, 2015, we do not foresee any significant changes to our unrecognized tax benefits within the next twelve months.

Brazil ICMS Tax Matter

Prior to our acquisition of Autocam, Autocam’s Brazilian subsidiary received notification from the Brazilian tax authorities regarding ICMS (State Value Added Tax or VAT) tax credits claimed on intermediary materials (tooling and perishable items) used in the manufacturing process. The Brazilian tax authority notification disallowed state ICMS credits claimed on intermediary materials based on the argument that these items are not intrinsically related to the manufacturing processes. Autocam Brazil filed an administrative defense with the Brazilian tax authority arguing, among other matters, that it should qualify for ICMS tax credit, contending that the intermediary materials are directly related to the manufacturing process.

We believe that we have substantial legal and factual defenses and plan to defend our interests in this matter vigorously. While we believe a loss is not probable, we estimate the range of possible loss related to this assessment is from $0 to $6,000. No amount was accrued at June 30, 2015 for this matter. There has been no change in the status of this matter from December 31, 2014 to June 30, 2015.

We are entitled to indemnification from the former shareholders of Autocam, subject to the limitations and procedures set forth in the agreement and plan of merger. Management believes the indemnification would include amounts owed for the tax, interest and penalties related to this matter.

All other legal proceedings are of an ordinary and routine nature and are incidental to our operations. Management believes that such proceedings should not, individually or in the aggregate, have a material adverse effect on our business, financial condition, results of operations or cash flows. In making that determination, we analyze the facts and circumstances of each case at least quarterly in consultation with our attorneys and determine a range of reasonably possible outcomes.

As part of the acquisition of Autocam, we acquired a 49% investment in a joint venture with an unrelated entity called Wuxi Weifu Autocam Precision Machinery Company, Ltd. (“JV”), a Chinese company located in Wuxi, China.

Below are the components of our JV investment balance at June 30, 2015:

Set forth below is summarized balance sheet information for the JV:

No dividends were declared by the JV during the three and six months ended June 30, 2015. We had sales to the JV of $44 and $64 during the three and six months ended June 30, 2015, respectively. Amounts due to us from the JV were $122 as of June 30, 2015. The JV had net sales in 2014 of $50,466 and net income of $9,004. In the first half of 2015, the JV had net sales and net income of $27,887 and $5,630, respectively.

Our policy is to manage interest expense using a mix of fixed and variable rate debt. To manage this mix effectively, we may enter into interest rate swaps in which we agree to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount.

On December 16, 2014, we entered into a $150,000 interest rate swap that will go into effect on December 29, 2015 (one year delayed start), at which time our interest rate will be locked at 7.216% until December 31, 2018. Prior to December 16, 2014, we did not have any existing interest rate hedges. The hedge instrument will be 100% effective and as such the mark to market gains or losses on this hedge will be included in accumulated other comprehensive income (loss) to the extent effective, and reclassified into interest expense over the term of the related debt instruments.

(In thousands, except per share data)

The table below summarizes the fair value measurements of the gross asset and liability of this swap as of June 30, 2015, valued on a recurring basis:

The interest rate swap derivative is classified as Level 2. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs which are derived from or corroborated by observable market data such as interest rate yield curves, index forward curves, discount curves, and volatility surfaces. Counterparties to these derivative contracts are highly rated financial institutions which we believe carry only a minimal risk of nonperformance.

We have elected to present the derivative contracts on a gross basis in the Condensed Consolidated Balance Sheet included within other non-current assets and other non-current liabilities. Had we chosen to present the derivative contract on a net basis, we would have a derivative in a net liability position of $2,056 as of June 30, 2015. We do not have any cash collateral due under such agreements.

Derivatives’ Hedging Relationships

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 SEC. The total number of shares of common stock sold was 7,590 at a public offering price of $24.00 per share. All of the shares in the offering were sold by NN. The net proceeds to NN from the offering, after deducting underwriting discounts and commissions and offering expenses, were approximately $173,052. Of these proceeds, $148,739 was used for repayment of principal and interest on our Term Loan B and ABL Revolver subsequent to quarter end and the remainder is currently being held in cash.

Results of Operations

Factors That May Influence Results of Operations

The following is a description of factors that have influenced our three and six months ended June 30, 2015 results of operations that we believe are important to provide an understanding of our business and results of operations.

2014 and 2015 Acquisitions

During the year ended December 31, 2014, we completed the acquisition of four companies: Autocam Corporation (“Autocam”), RFK Valjcici d. d. Konjic (“RFK”), V-S Industries, V-S Precision, LLC and V-S Precision SA de DV(collectively referred to as “VS”) and Chelsea Grinding (“Chelsea”). The acquisitions of Autocam and Chelsea occurred subsequent to June 30, 2014. The RFK acquisition was completed June 20, 2014, which allowed for only ten days being included in the second quarter of 2014. Additionally, we acquired Caprock on May 29, 2015 and included one month of sales and income in the second quarter of 2015. 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 below for the three and six month periods ended June 30, 2015, the impacts of the four acquisitions completed subsequent to the second quarter of 2014. The remaining changes relate to the legacy NN businesses. For more information about the 2014 acquisitions including background on the acquired companies, the purchase price allocations and pro forma information, as required, please refer to Note 2 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 which we filed with the SEC on March 16, 2015 and Note 2 of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

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 accelerating during the fourth quarter of 2014 and the first quarter of 2015. During these periods, the Euro to U.S. Dollar rate dropped from approximately 1.36 in mid-July 2014 to 1.08 at March 31, 2015 representing an approximate 20% decline in value. During the second quarter of 2015 the euro recovered 3.5% of its value to end up at 1.12. The devaluation of the Euro significantly impacted the translation of our Euro denominated sales and costs when comparing the three and six months ended June 30, 2015 to the three and six months ended June 30, 2014. The Euro devaluation from translation negatively impacted the three and six months ended June 30, 2015 sales by $9.3 million and $17.6, respectively, and net income by $0.9 million and $1.7 million, respectively. The Euro translation impact, and the translation impact of other currencies, is highlighted below as “foreign exchange effects”. In addition to the translation effects, the devaluation of the Euro impacted the value of certain intercompany loan receivables denominated in Euros that resulted in an unfavorable transactional impact to earnings of $1.0 million reported below in “Other expense, net” for the six months ended June 30, 2015.

OVERALL RESULTS

We have provided a reconciliation of net income to adjusted net income (a non-GAAP measure used by management) and income from operations to adjusted income from operations (a non-GAAP measure used by management) to provide supplementary information about the impacts of acquisition related expenses and foreign exchange impacts on intercompany loans. We believe that the presentation of adjusted income from operations and adjusted net income provides useful information to investors in assessing our results of operations and potential future results. These measures should not be considered as an alternative to GAAP net income or income from operations. You should not consider adjusted net income or adjusted income from operations in isolation, or as a substitute for analysis of our results as reported under GAAP. Additionally, because adjusted net income or adjusted income from operations may be defined differently by other companies in our industry, our definitions may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Table of Contents

Three Months Ended June 30, 2015 Compared to the Three Months Ended June 30, 2014

Net Sales. Net sales increased during the second quarter of 2015 from the second quarter of 2014 principally due to sales from the companies acquired in 2014 and 2015 subsequent to the second quarter of 2014. Additionally, sales increased from greater demand for our products in the European and North American markets served by our Metal Bearing Components Segment, namely automotive and general industrial markets. Partially offsetting these increases was the impact of devaluation of the Euro on Euro denominated sales, as discussed above.

16

Table of Contents

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 from the companies acquired during 2014 and 2015, as discussed above. Additionally, the total was impacted by increased production costs at those units that experienced higher sales volumes, as discussed above. Partially offsetting these increases was the impact of the devaluation of the Euro on Euro denominated costs, as discussed above.

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 2014 and 2015.

Depreciation and amortization. The increase in 2015 was due to depreciation and amortization from the acquisitions closed in 2014. This 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 $5.4 million in 2015 from the interest on the debt we undertook to complete the four acquisitions in 2014.

Provision for income taxes. The second quarter of 2015 effective tax rate of 21% is lower than the second quarter of 2014 effective tax rate of 31% primarily due to the geographic mix of pre-tax income. In the second quarter of 2015, a larger proportion of the pre-tax income was earned in foreign jurisdictions with lower statutory rates than that of the U.S.

RESULTS BY SEGMENT

METAL BEARING COMPONENTS SEGMENT

Net sales decreased during the second quarter of 2015 from the second quarter of 2014 principally due to the devaluation of the Euro on Euro denominated sales, as discussed above. Partially offsetting the foreign exchange impacts was greater demand for our products in the North American and European automotive markets. This greater demand was from market share gains with our customers and from winning business with new customers. Finally, sales increased with the addition of the companies the segment acquired in 2014.

The main drivers of the increased income from operations for the segment were $1.0 million in incremental income from the increased sales volumes and $0.2 million in additional income from operations of the acquired companies. Additionally, segment income from operation was favorably impacted by $0.6 from continuous improvement projects. Segment income from operations was unfavorably impacted $1.3 million due to the depreciation in value of Euro denominated income from operations relative to the U.S. Dollar.

17

Table of Contents

AUTOCAM PRECISION COMPONENTS SEGMENT

The increased sales in the second quarter of 2015 were due to sales added with the acquisition subsequent to the second quarter of 2014. The addition of the acquired company added $7.1 million to segment income from operations.

PLASTIC AND RUBBER COMPONENTS SEGMENT

The increase in sales and net income during the second quarter of 2015 was due primarily to the acquisition of Caprock.

Net Sales. Net sales increased during the first half of 2015 from the first half of 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. Additionally, sales increased from greater demand for our products in the European, Asian and North American markets served by our Metal Bearing Components Segment, namely automotive and general industrial markets. This sales growth came from overall 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 four companies acquired during 2014 and 2015, as discussed above. Additionally, the total was impacted by increased production costs at those units that experienced higher sales volumes, as discussed above. Partially offsetting these increases was the impact of devaluation of the Euro on Euro denominated costs, as discussed above.

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 2014 subsequent to the first half of 2014.

Depreciation and amortization. The increase in 2015 was due to depreciation and amortization from the four acquisitions closed in 2014. 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 the four acquisitions in 2014.

Other expense, net. Included in other expense, net during the first half of 2015 was $1.0 million related to foreign exchange losses on inter-company loans. These losses are a function of the depreciation of the Euro versus the U.S. Dollar.

Provision for income taxes. The first half of 2015 effective tax rate of 22% is lower than the first half of 2014 effective tax rate of 32% primarily due to the geographic mix of pre-tax income. In the first half of 2015, a larger proportion of the pre-tax income was earned in foreign jurisdictions with lower statutory rates than that of the U.S.
