FOR IMMEDIATE RELEASE

NN, INC. REPORTS STRONG SALES GROWTH AND IMPROVED OPERATING MARGINS FOR FIRST QUARTER 2021

First Quarter Net Sales Increased 9.1% Over Prior Year, Driving EBITDA to $16.9 Million on an Adjusted Basis

Charlotte, N.C., May 6, 2021 – NN, Inc. (NASDAQ: NNBR), a diversified industrial company, today reported its financial results for the first quarter ended March 31, 2021.

GAAP Results

Net sales for the first quarter of 2021 increased $10.6 million, or 9.1%, to $126.8 million, compared to $116.2 million for the first quarter of 2020, led by strong sales from Mobile Solutions, which increased 11.3%.

On a GAAP basis, income from operations for the first quarter of 2021 was $1.0 million, compared to loss from operations of $103.9 million for the same period in 2020. In the first quarter of 2021, the income from operations was primarily driven by an increase in sales volume and cost reduction initiatives. Income from operations for the first quarter of 2020 was impacted by a non-cash goodwill impairment of $92.9 million in the Power Solutions segment.

On a GAAP basis, income from operations for first quarter 2021 in the Mobile Solutions segment was $6.1 million, compared to income from operations of $0.3 million for the same period in 2020. On a GAAP basis, income from operations for first quarter 2021 in the Power Solutions segment was $2.4 million, compared to loss from operations of $90.3 million for the same period in 2020.

Net loss on a GAAP basis for the first quarter of 2021 was $4.9 million, compared to net loss on a GAAP basis of $248.2 million in the first quarter of 2020. Net loss on a GAAP basis for the first quarter of 2021 was driven by costs related to the refinancing transaction and termination of the interest rate swap, which were partially offset by the gross profit generated from incremental sales volume, operating efficiencies, reductions in SG&A, and interest expense. Net loss on a GAAP basis for the first quarter of 2020 was impacted by the non-cash goodwill impairment referenced above and the loss from discontinued operations of $140.1 million from the former Life Sciences business.

Adjusted Results

Adjusted income from operations for the first quarter of 2021 was $6.4 million, compared to $1.3 million for the same period in 2020. Adjusted EBITDA for the first quarter of 2021 was $16.9 million, or 13.3% of sales, versus $10.1 million, or 8.7% of sales, for the same period in 2020. Adjusted net income was $2.2 million, or $0.05 per diluted share, compared to adjusted net loss of $6.6 million, or $0.16 per diluted share, for the same period in 2020. Free cash flow for the first quarter of 2021 was $2.4 million, compared to a use of cash of $1.0 million for the same period in 2020.

Warren Veltman, President and Chief Executive Officer, said, “We are encouraged by the strong sequential and year-over-year growth we saw across our Mobile Solutions and Power Solutions businesses in the first quarter. We experienced strong growth in North America and our wholly owned China operations, driven by improved customer demand across our end markets. Our China joint venture also showed strong profitability during the quarter contributing to a $1.7 million improvement from prior year. Our sales volume, cost reductions, and improved manufacturing efficiencies all contributed to improve our bottom line and free cash flow generation during the quarter.”

Mobile Solutions

Net sales for the first quarter of 2021 were $77.8 million, compared to $69.9 million in the first quarter of 2020, an increase of $7.9 million, or 11.3%. The increase in sales was driven by higher demand within all markets that were negatively impacted by the pandemic in the prior year, as well as new business in the general industrial market. Adjusted income from operations for the first quarter of 2021 was $7.1 million, compared to $1.5 million of adjusted operating income in the first quarter of 2020. Adjusted operating income increased as a result of the increase in sales as well as variable and fixed cost reduction initiatives.

Power Solutions

Net sales for the first quarter of 2021 were $49.1 million, compared to $46.4 million in the first quarter of 2020, an increase of $2.7 million, or 5.8%. The increase in sales was driven primarily by higher commodity pricing on precious metals which are passed through at lower margins. The increase in sales was partially offset by decreases in demand from the electrical and medical markets as demand has been dampened by the pandemic, which did not begin to impact the segment until the second quarter of 2020. Adjusted income from operations for the quarter was $5.5 million, compared to $7.0 million in the first quarter of 2020. The reduction in adjusted operating income was due primarily to the lower margins on precious metals as well as the product mix which reduced overall segment profitability.

Mr. Veltman concluded, “Throughout the first quarter of 2021, we continued to make progress in executing our strategic plan by successfully completing our refinancing, providing us a long-term runway to achieve our 2025 goals for revenue and profitability growth. We also added new directors to our Board who possess specific experience and skill sets to assist our management team in shaping our strategy to leverage growth opportunities created by the evolution of the power grid and electric vehicles. Looking forward, we will continue to maintain our focus on end market penetration to drive growth and cost discipline to improve profitability, while remaining judicious in our capital investments.”

The Company discloses in this presentation the non-GAAP financial measures of adjusted income from operations, adjusted EBITDA, adjusted net income (loss), adjusted net income per diluted share, free cash flow and net debt. Each of these non-GAAP financial measures provides supplementary information about the impacts of acquisition, divestiture and integration related expenses, foreign-exchange impacts on inter-company loans, reorganizational and impairment charges. Over the past five years, we have completed several acquisitions, two of which were transformative for the Company, and sold three of our businesses. The costs we incurred in completing such acquisitions, including the amortization of intangibles and deferred financing costs, and these divestitures have been excluded from these measures because their size and inconsistent frequency are unrelated to our commercial performance during the period, and which we believe are not indicative of our ongoing operating costs. We exclude the impact of currency translation from these measures because foreign exchange rates are not under management’s control and are subject to volatility. Other non-operating charges are excluded as the charges are not indicative of our ongoing operating cost. We believe the presentation of adjusted income from operations, adjusted EBITDA, adjusted net income (loss), adjusted net income per diluted share, free cash flow and net debt provides useful information in assessing our underlying business trends and facilitates comparison of our long-term performance over given periods.

The non-GAAP financial measures provided herein may not provide information that is directly comparable to that provided by other companies in the Company’s industry, as other companies may calculate such financial results differently. The Company’s non-GAAP financial measures are not measurements of financial performance under GAAP and should not be considered as alternatives to actual income growth derived from income amounts presented in accordance with GAAP. The Company does not consider these non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial results.

(a) Non-GAAP Adjusted income from operations represents GAAP income from operations, adjusted to exclude the effects of restructuring and integration expense; non-operational charges related to acquisition and transition expense, intangible amortization costs for fair value step-up in values related to acquisitions, non-cash impairment charges, and when applicable, our share of income from joint venture operations. We believe this presentation is commonly used by investors and professional research analysts in the valuation, comparison, rating, and investment recommendations of companies in the industrial industry. We use this information for comparative purposes within the industry. Non-GAAP adjusted income from operations is not a measure of financial performance under GAAP and should not be considered as a measure of liquidity or as an alternative to GAAP income from operations.

(b) Non-GAAP adjusted EBITDA represents GAAP net income (loss), adjusted to include income taxes, interest expense, write-off of unamortized debt issuance costs, interest rate swap payments and change in fair value, change in fair value of preferred stock derivatives and warrants, depreciation and amortization, charges related to acquisition and transition costs, non-cash stock compensation expense, foreign exchange gain (loss) on inter-company loans, restructuring and integration expense, costs related to divested businesses and litigation settlements, income from discontinued operations, and non-cash impairment charges, to the extent applicable. We believe this presentation is commonly used by investors and professional research analysts in the valuation, comparison, rating, and investment recommendations of companies in the industrial industry. We use this information for comparative purposes within the industry. Non-GAAP adjusted EBITDA is not a measure of financial performance under GAAP and should not be considered as a measure of liquidity or as an alternative to GAAP income (loss) from continuing operations.

(c) This line item reflects the aggregate tax effect of all nontax adjustments reflected in the respective table. NN, Inc. estimates the tax effect of the adjustment items identified in the reconciliation schedule above by applying the applicable statutory rates by tax jurisdiction unless the nature of the item and/or the tax jurisdiction in which the item has been recorded requires application of a specific tax rate or tax treatment.

(d) Non-GAAP adjusted net income (loss) represents GAAP net income (loss) adjusted to exclude the tax-affected effects of charges related to acquisition and transition costs, foreign exchange gain (loss) on inter-company loans, restructuring and integration charges, amortization of intangibles costs for fair value step-up in values related to acquisitions and amortization of deferred financing costs, non-cash impairment charges, write-off of unamortized debt issuance costs, interest rate swap payments and change in fair value, change in fair value of preferred stock derivatives and warrants, costs related to divested businesses and litigation settlements, income (loss) from discontinued operations, and preferred stock cumulative dividends and deemed dividends. We believe this presentation is commonly used by investors and professional research analysts in the valuation, comparison, rating, and investment recommendations of companies in the industrial industry. We use this information for comparative purposes within the industry. Non-GAAP adjusted income (loss) from segment operations is not a measure of financial performance under GAAP and should not be considered as a measure of liquidity or as an alternative to GAAP income (loss) from continuing operations.
