Exhibit 3.1

CERTIFICATE OF DESIGNATION

SERIES D PERPETUAL PREFERRED STOCK

NN, INC.

Pursuant to Section 151 of the General Corporation Law of the State of Delaware:

NN, Inc., a Delaware corporation (the “Corporation”), hereby certifies that, in accordance with the provisions of Section 151 of the General Corporation Law of the State of Delaware (“DGCL”), the Board of Directors of the Corporation has duly adopted the following resolutions:

RESOLVED, that, pursuant to Article IV of the Corporation’s Restated Certificate of Incorporation, as amended (which authorizes 5,000,000 shares of preferred stock, par value $0.01 per share of the Corporation (the “Preferred Stock”)), the Board of Directors of the Corporation hereby fixes the powers, designations, preferences and relative, participating, optional and other special rights, and the qualifications, limitations and restrictions, of a series of Preferred Stock as follows:

Section 1. Designation. There is hereby created out of the authorized and unissued shares of Preferred Stock of the Corporation a new series of Preferred Stock designated as the “Series D Preferred Stock”. The number of shares constituting the Series D Preferred Stock will be 65,000.

Section 2. Ranking. The Series D Preferred Stock shall rank, with respect to the payment of dividends and other distributions, including the distribution of assets upon liquidation, dissolution or winding up of the Corporation, (i) senior to the Common Stock and to any other class or series of the Preferred Stock, and (ii) junior to any existing or future secured or unsecured indebtedness of the Corporation.

Section 3. Dividends.

3.1 Holders of Series D Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors, and the Corporation shall pay, out of funds lawfully available therefor, cumulative quarterly dividends payable in cash (a “Series D Dividend”) on March 31, June 30, September 30, and December 31 in each year (each such date being referred to as a “Dividend Payment Date”), commencing on the first Dividend Payment Date after the Issuance Date, in an amount equal to 10.0% per annum of the Initial Liquidation Preference per share of Series D Preferred Stock (the “Cash Dividend Rate”). The period from the Issuance Date to and including March 31, 2021 and each period from but excluding a Dividend Payment Date to and including the following Dividend Payment Date is herein referred to as a “Dividend Period”. On any such Dividend Payment Date, if the Series D Dividend is not so paid in cash, the Liquidation Preference per share of Series D Preferred Stock shall be increased by an amount equal to 12.0% per annum (the “Preference Accrual Rate”) on the then current Liquidation Preference per share of Series D Preferred Stock (the “Liquidation Preference Adjustment”). On the Specified Date, the Cash Dividend Rate and the Preference Accrual Rate, expressed as a percentage, shall each increase by an amount equal to 2.5%, and shall continue to increase by an amount equal to 2.5% on each anniversary date following the Specified Date (such increase on the Specified Date and each anniversary thereafter, the “Specified Date Adjustment”). In addition to the foregoing, beginning on the Dividend Payment Date on September 30, 2027 and continuing on every Dividend Payment Date thereafter, the Board of Directors shall declare and the Company shall pay in cash a Series D Dividend unless otherwise prohibited by Delaware law or any then effective credit agreement to which the Corporation is then a party. For so long as any shares of Series D Preferred Stock remain issued and outstanding, the Liquidation Preference per share of Series D Preferred Stock shall continue to be adjusted pursuant to this Section 3.1 on each Dividend Payment Date.

3.2 Series D Dividends shall be payable in arrears on each Dividend Payment Date and shall accrue, whether or not earned or declared, from the most recent Dividend Payment Date, or, in the case of the first Dividend Payment Date, from the Issuance Date. Series D Dividends shall accrue on each outstanding share of Series D Preferred Stock on the basis of twelve 30-day months and a 360-day year, at the Cash Dividend Rate on the basis of the Liquidation Preference with respect to such share, as adjusted by the Liquidation Preference Adjustments that occurred on each Dividend Payment Date for which the Series D Dividend was not paid with respect to such share.

Section 4. Liquidation, Dissolution or Winding Up.

4.1 Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation (a “Liquidation”), after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of Series D Preferred Stock shall be entitled to receive, in respect of any shares of Series D Preferred Stock held by them, out of assets of the Corporation available for distribution to stockholders of the Corporation or their assignees, and subject to the rights of any outstanding shares of Senior Securities and before any amount shall be distributed to the holders of Junior Securities, a liquidating distribution (the “Liquidation Distribution”) in an amount equal to the Liquidation Preference. If, upon a Liquidation, the assets of the Corporation, or proceeds thereof, distributable among the holders of the then outstanding shares of Series D Preferred Stock and the holders of any shares of Parity Securities ranking on a parity with the Series D Preferred Stock with respect to any distribution of assets upon Liquidation are insufficient to pay in full the amount such Liquidation Distribution and all liquidation preference payable with respect to any such Parity Securities, then the holders of Series D Preferred Stock and such Parity Securities shall share ratably in any distribution of assets in proportion to the full respective preferential amounts to which they are entitled.

4.2 The Corporation shall provide the holders of Series D Preferred Stock appearing on the stock books of the Corporation as of the date of such notice at the address of said holder shown therein with written notice of any Liquidation not less than thirty (30) days prior to the payment date stated therein, which notice shall set forth the payment date, the amount of proceeds to be paid with respect to each share of Series D Preferred Stock and each share of Senior Securities, Parity Securities and Junior Securities in connection therewith; provided that in the case of any involuntary Liquidation, the Corporation shall provide notice within ten (10) Business Days upon the Corporation becoming aware of any instituted proceeding in respect thereof.

4.3 After the payment in cash or proceeds to the holders of shares of the Series D Preferred Stock of the full amount of the Liquidation Distribution with respect to outstanding shares of Series D Preferred Stock, the holders of outstanding shares of Series D Preferred Stock shall have no right or claim, based on their ownership of shares of Series D Preferred Stock, to the remaining assets of the Corporation, if any. Whenever any such distribution shall be paid in property other than cash, the value of such distribution shall be the fair market value of such property, as determined in the good faith reasonable discretion of the Board of Directors or liquidating trustee, as the case may be, and each holder of shares of the Series D Preferred Stock shall be notified in writing of such distribution and of the value of such other securities or property at least thirty (30) days prior to the scheduled distribution. If, however, holders of a majority of the outstanding shares of Series D Preferred Stock shall give the Board of Directors written notice at least twenty (20) days prior to the scheduled distribution that such holders disagree with the value placed upon such property (other than cash) by the Board of Directors, then such holders and the Board of Directors shall attempt to agree upon a fair market value. Should such holders and the Board of Directors be unable to agree during the five-day period immediately following the

giving of the written notice of such disagreement as to the fair market value without the employment of appraisers, then the Corporation, on the one hand, and such holders, on the other hand, shall each select an appraiser experienced in the business of evaluating or appraising the market value of the relevant securities or property other than securities. The appraisers so selected (the “Initial Appraisers”) shall, on or prior to the scheduled distribution, appraise such securities or other property. If the difference between the resulting appraisals is no greater than ten percent of the higher appraisal, then the average of the appraisals shall be deemed the fair market value; otherwise, the Initial Appraisers shall select an additional appraiser (the “Additional Appraiser”), who shall be experienced in a manner similar to the Initial Appraisers. The Additional Appraiser shall then choose from the values determined by the Initial Appraisers the value that the Additional Appraiser considers closest to the fair market value of the property to be distributed, and such value shall be the fair market value. The Corporation shall pay the expenses and fees of each Appraiser. The fair market value determined pursuant to this provision shall apply to all holders of Series D Preferred Stock, including any holders of Series D Preferred Stock not providing notice of a challenge pursuant to this provision.

4.4 For purposes of this Section 4, the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property and assets of the Corporation (by way of merger, consolidation or otherwise) shall not be deemed a voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, nor shall the merger, consolidation, statutory exchange or any other business combination transaction of the Corporation into or with any other Person or the merger, consolidation, statutory exchange or any other business combination transaction of any other Person into or with the Corporation be deemed to be a voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation.

Section 5. Voting Rights.

5.1 Voting Generally. Except as otherwise set forth herein or to the extent required by the DGCL, the holders of the Series D Preferred Stock shall have no voting rights, and their consent shall not be required for taking any corporate action.

5.2 Adverse Changes. So long as any shares of Series D Preferred Stock remain outstanding, the affirmative vote or consent of the holders of at least a majority of the shares of Series D Preferred Stock outstanding at such time, voting together as a separate class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating any of the following actions by the Corporation, whether or not such approval is required pursuant to the DGCL:

(i) any amendment or waiver (whether by merger, consolidation or otherwise) of any provision of the Organizational Documents (as defined in the Securities Purchase Agreement) of the Corporation or any of its Subsidiaries, in either case, in a way that materially and adversely affects the rights, preferences and privileges or power of the Series D Preferred Stock;

(ii) the authorization, creation or issuance of, or the combination or reclassification of any securities into (in each case whether by merger, consolidation, or otherwise), any additional shares of Series D Preferred Stock, any Parity Securities or any Senior Securities or any other class or series of Capital Stock of the Corporation or its Subsidiaries ranking senior to (or otherwise having a priority on payment to), or on a parity basis with, the Series D Preferred Stock as to dividend or distribution rights, redemption rights or rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation;

(iii) the declaration or payment of any dividend or distribution on, or redemption or repurchase of, any issued and outstanding shares of Common Stock or any other Junior Securities; provided that the Corporation may (a) acquire shares of Common Stock or Junior Securities in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of present or former employees or directors of the Corporation and its Subsidiaries for the purposes of satisfying applicable taxes or netting of applicable exercise price or otherwise as required by any such plan, agreement or arrangement; and (b) acquire Junior Securities as a result of an exchange or conversion of such shares of Junior Securities for any other shares of Junior Securities and purchase any fractional shares of Junior Securities in connection therewith; and

(iv) the incurrence of Indebtedness, other than (a) any Indebtedness that would be permitted to be incurred under both the New Term Loan and the New ABL, (b) without duplication of the foregoing, any Indebtedness incurred to refinance or replace Indebtedness outstanding on the Issuance Date (including successive refinancings or replacements), in an aggregate principal amount at maturity not to exceed the sum of (1) the principal amount at maturity of the Indebtedness being refinanced, (2) accrued and unpaid interest on the Indebtedness being refinanced, (3) premiums, fees and expenses payable in connection with the repayment of such and provided that after such incurrence the Corporation and its Subsidiaries would not have a Consolidated Net Leverage Ratio greater than 3.50:1.00, and (c) any Indebtedness, the net proceeds of which are contemporaneously used to redeem outstanding shares of Series D Preferred Stock;

(v) the making of any Dispositions unless (a) such Dispositions are otherwise permitted under the New Term Loan and the New ABL and (b) the Corporation uses the Net Cash Proceeds from such Disposition to permanently repay Indebtedness and extinguish all commitments for the Indebtedness and, insofar as there are any remaining Net Cash Proceeds from any Dispositions after repayment and extinguishment of all such Indebtedness in excess of $25 million, such excess is applied to redeem shares of Series D Preferred Stock;

(vi) any voluntary Liquidation or bankruptcy filing; and

(vii) agree to take any of the foregoing actions.

provided, however, that the authorization or creation of, or the increase in the number of authorized or issued shares of, or any securities convertible into shares of, or the reclassification of any security (other than the Series D Preferred Stock) into, or the issuance of, Junior Securities will not require the vote of the holders of the Series D Preferred Stock as long as the proceeds from any such issuance consist entirely of cash and the net proceeds are used by the Corporation to repay indebtedness of the Corporation and/or its Subsidiaries from any such issuance (after payment of related expenses and underwriting, placement agent or broker fees in connection with such issuance) or to redeem shares of Series D Preferred Stock and/or pay any Series D Dividend, or pursuant to an equity incentive plan.

5.3 Remedies. In addition to, and without limiting, any of the rights and remedies the holders of Series D Preferred Stock would have at law or in equity, in the event of a breach of any provision of Section 5.2 by the Corporation or its Subsidiaries: (a) the Corporation shall be required to give prompt notice of such breach to the holders of Series D Preferred Stock; (b) the then effective Cash Dividend Rate and Preference Accrual Rate shall each increase by an amount equal to 4.0% per annum above the amount otherwise applicable under Section 3.1 hereof (and subject to additional increases pursuant to the terms thereof) from the date such breach first occurred until the date (if any) that the Corporation shall have remedied such breach; and (c) in the event that the Corporation shall not have cured such breach within thirty (30) days of the first occurrence of the breach, each holder of Series D Preferred Stock shall have the right to require the redemption of, and the Corporation shall be required to redeem, any or all of its shares of Series D Preferred Stock in accordance with the terms and procedures set forth in Section 7.2(i)(b).
