We are paying the cost of registering the shares covered by this prospectus as well as various related expenses.

PROSPECTUS SUMMARY
This summary highlights certain information about us, the Private Placement and selected information contained elsewhere in or incorporated by reference into this prospectus. This summary is not complete and does not contain all of the information that you should consider before making an investment decision. For a more complete understanding of our company, you should read and consider carefully the more detailed information included or incorporated by reference in this prospectus and any applicable prospectus supplement, including the factors described under the heading “Risk Factors” on page 4 of this prospectus, as well as the information incorporated herein by reference, before making an investment decision.
Company Overview
NN, Inc., a Delaware corporation, is a diversified industrial company that combines advanced engineering and production capabilities with in-depth materials science expertise to design and manufacture high-precision components and assemblies for a variety of end markets on a global basis.
Our enterprise and management structure is designed to accelerate growth and further balance our portfolio by aligning our strategic assets and businesses. Our businesses are organized into the Mobile Solutions group, which is focused on growth in the automotive, general industrial, and medical end markets, and the Power Solutions group, which is focused on growth in the electrical, general industrial, automotive, and medical end markets, and are based on the nature of the products manufactured.
Corporate Information
We were incorporated in Delaware in October 1980. Our principal executive offices are maintained at 6210 Ardrey Kell Road, Suite 120, Charlotte, North Carolina 28277 and our telephone number is (980) 264-4300. Our website address is www.nninc.com. The information contained on, or accessible through, our website is not incorporated by reference into this prospectus, and you should not consider any information contained in, or that can be accessed through, our website as part of this prospectus or in deciding whether to purchase our securities. We have included our website in this prospectus solely as an inactive textual reference.
Private Placement
On October 1, 2026, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors named in this prospectus pursuant to which we agreed to sell and issue (i) 11,275,605 shares of common stock at a purchase price of $3.30 per share and (ii) Pre-Funded Warrants to purchase 4,824,395 shares of common stock at a purchase price of $3.29 per Pre-Funded Warrant (which equals the per share purchase price of the common stock minus the $0.01 per share exercise price of each Pre-Funded Warrant). The Private Placement closed on October 5, 2026. The total aggregate purchase price paid by the Selling Stockholders was approximately $53 million, and we received net proceeds of approximately $50 million after deducting placement agent fees and other offering expenses.
In connection with the Private Placement, on October 1, 2026, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Selling Stockholders named in this prospectus, pursuant to which we agreed to prepare and file, within 45 days following the date of the Registration Rights Agreement, a registration statement with the SEC to register for resale the shares of our common stock issued at the closing under the Purchase Agreement and the shares issuable upon exercise of the Pre-Funded Warrants, and to use commercially reasonable efforts to cause the registration statement to promptly become effective.
For additional information regarding the Purchase Agreement and Registration Rights Agreement, refer to the summary of the Private Placement included under Item 1.01 of our Current Report on Form 8-K filed with the SEC on October 5, 2026, which is incorporated by reference herein.

Implications of Being a Smaller Reporting Company
We are a smaller reporting company and may continue to be a smaller reporting company if either (i) the market value of our shares held by non-affiliates is less than $250 million on the last business day of our most recently completed second fiscal quarter in our last completed fiscal year or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our shares held by non-affiliates is less than $700 million. Specifically, as a smaller reporting company, we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and are subject to reduced disclosure obligations regarding executive compensation.

RISK FACTORS
Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described under the heading “Risk Factors” contained in any applicable prospectus supplement and any related free writing prospectus, and under similar headings in our most recent Annual Report on Form 10-K, as updated by our subsequent annual, quarterly and other reports and documents that are incorporated by reference into this prospectus and any applicable prospectus supplement before deciding whether to purchase any of our securities being registered pursuant to the registration statement of which this prospectus is a part. Each of the risk factors described in the documents referenced above could adversely affect our business, operating results, and financial condition, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial, may also significantly impair our business operations. Please also read carefully the section below titled “Special Note Regarding Forward-Looking Statements.”

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus, each applicable prospectus supplement, and the information incorporated by reference in this prospectus and each prospectus supplement contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and include this statement for purposes of complying with these safe harbor provisions. Forward-looking statements generally will be accompanied by words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “growth,” “guidance,” “intend,” “may,” “possible,” “potential,” “predict,” “project,” “trajectory,” “will” or the negative of those terms, and similar expressions that convey uncertainty of future events or outcomes. Forward-looking statements involve a number of risks and uncertainties that are outside of management’s control and that may cause actual results to be materially different from such forward-looking statements. Such factors include, among others, general economic conditions and economic conditions in the industrial sector; competitive influences; risks that current customers will commence or increase captive production; risks of capacity underutilization; quality issues; inflationary pressures and material changes in the cost or availability of raw materials, supply chain shortages and disruptions, the availability of labor and labor disruptions along the supply chain; our dependence on certain major customers, some of whom are not parties to long-term agreements (and/or are terminable on short notice); the impact of acquisitions and divestitures, as well as expansion of end markets and product offerings; our ability to hire or retain key personnel; the restrictions contained in our debt agreements; the level of our indebtedness and our ability to obtain financing at favorable rates, if at all, or to refinance existing debt as it matures; our ability to secure, maintain or enforce patents or other appropriate protections for our intellectual property; the impact of climate change on our operations; economic, social, political and geopolitical instability, military conflict, currency fluctuation, and other risks of doing business outside of the United States; uncertainty of government policies and actions in respect to global trade and tariffs, including the potential impacts of tariffs on the United States economy, the economy of other countries in which we conduct operations and our industry; cyber liability or potential liability for breaches of our or our service providers’ information technology systems or business operations disruptions; and other risks and uncertainties set forth in documents filed, or to be filed, with the SEC. For the reasons described above, we caution against relying on any forward-looking statements, which should also be read in conjunction with the sections entitled “Business,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in other sections incorporated by reference from our Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, as applicable, as well as our other filings with the SEC. You should be aware that the occurrence of any of the events discussed under the heading “Risk Factors” in any applicable prospectus supplement and any documents

Table of Contents
incorporated by reference herein or therein could substantially harm our business, operating results, and financial condition and that if any of these events occurs, it could adversely affect the value of an investment in our securities.

The cautionary statements made in this prospectus are intended to be applicable to all related forward-looking statements wherever they may appear in this prospectus or in any prospectus supplement or any documents incorporated by reference herein or therein. We urge you not to place undue reliance on these forward-looking statements, which speak only as of the date they are made. Except as required by law, we assume no obligation to update our forward-looking statements, even if new information becomes available in the future.

USE OF PROCEEDS
We will not receive any of the proceeds from the sale or other disposition of shares of our common stock held by the Selling Stockholders pursuant to this prospectus. We will receive nominal proceeds from the exercise of the Pre-Funded Warrants if such warrants are exercised for cash at the exercise price of $0.01 per share. We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of shares of our common stock to be sold by the Selling Stockholders pursuant to this prospectus.

DESCRIPTION OF CAPITAL STOCK
General
Our authorized capital stock consists of 185,000,000 shares, consisting of 180,000,000 shares of common stock, $0.01 par value per share, and 5,000,000 shares of preferred stock, $0.01 par value per share (“Preferred Stock”). Our board of directors (the “Board”) is authorized, without stockholder approval, except as required by the listing standards of the Nasdaq Stock Market, to issue additional shares of our capital stock. In addition, our board of directors may, without further action by our stockholders, designate the rights, preferences, privileges, and restrictions of our Preferred Stock in one or more series.
As of October 7, 2026, we had outstanding 93,744,210 shares of common stock.
Common Stock
The following description of common stock is a summary and is qualified in its entirety by reference to the actual terms and provisions contained in our Restated Certificate of Incorporation, as amended from time to time (the “Certificate of Incorporation”), and our Amended and Restated Bylaws, as amended from time to time (the “Bylaws”), each of which is filed as an exhibit to the registration statement of which this prospectus is a part. We encourage you to read our Certificate of Incorporation, our Bylaws, and the applicable provisions of the Delaware General Corporation Law (“DGCL”) for additional information.
Dividends
Subject to preferential rights of any other class or series of Preferred Stock, holders of common stock may receive dividends pro rata out of assets that we can legally use to pay dividends, when, as and if they are declared by our Board.
Voting Rights
Holders of common stock will have the exclusive power to vote on all matters presented to our stockholders, including the election of directors, except as otherwise provided by Delaware law or as provided with respect to any other class or series of stock. Holders of common stock are entitled to one vote per share. There is no cumulative voting in the election of our directors, which means that, subject to any rights to elect directors that are granted to the holders of any class or series of Preferred Stock, a majority of the votes cast at a meeting of stockholders at which a quorum is present is required to elect a director in any uncontested election and a plurality of the votes cast at a meeting of stockholders at which a quorum is present is required to elect a director in any contested election.
Liquidation Rights
In the event we are liquidated, dissolved or our affairs are wound up, after we pay or make adequate provision for all of our known debts and liabilities, each holder of common stock will receive dividends pro rata out of assets that we can legally use to pay distributions, subject to any rights that are granted to the holders of any class or series of Preferred Stock.
Fully Paid and Nonassessable
The outstanding shares of our common stock are fully paid and nonassessable.

Table of Contents
Absence of Other Rights
Holders of common stock have no preference, appraisal or exchange rights, except for any appraisal rights provided by Delaware law. Furthermore, holders of common stock have no conversion, sinking fund or redemption rights, or preemptive rights to subscribe for any of our securities.
Preferred Stock
Our Certificate of Incorporation authorizes our Board, without stockholder approval, to designate and issue up to 5,000,000 shares of Preferred Stock, in one or more series and to fix the rights, preferences, privileges and restrictions granted to or imposed upon each such series of Preferred Stock, including voting rights, dividend rights, conversion rights, terms of redemption, liquidation preference, sinking fund terms, subscription rights and the number of shares constituting any series or the designation of a series. Our Board can issue, without stockholder approval, Preferred Stock with voting and conversion rights that could adversely affect the voting power of the holders of common stock and reduce the likelihood that such holders will receive dividend payments or payments upon liquidation. Such issuance could have the effect of decreasing the market price of the common stock. The issuance of Preferred Stock or even the ability to issue Preferred Stock could also have the effect of delaying, deterring or preventing a change of control or other corporate action. There are currently no issued and outstanding shares of Preferred Stock.
Warrants
As of October 5, 2026, there were Pre-Funded Warrants to purchase up to 4,824,395 shares of common stock at an exercise price of $0.01 per share outstanding, which are exercisable at any time until exercised in full. In addition, as of October 5, 2026, there were warrants to purchase up to 1,215,000 shares of common stock at an exercise price of $11.03 per share outstanding, which are exercisable, in full or in part, at any time prior to December 11, 2026.
Pre-Funded Warrants
In connection with the Private Placement, we issued Pre-Funded Warrants to purchase 4,824,395 shares of common stock. The Pre-Funded Warrants have an exercise price of $0.01 per share, are immediately exercisable, and may be exercised at any time until exercised in full. The Pre-Funded Warrants may be exercised on a cashless basis. The exercise price and number of shares of common stock issuable upon exercise of the Pre-Funded Warrants are subject to adjustment for stock splits, stock dividends, reclassifications and similar events.
A holder of a Pre-Funded Warrant may not exercise the warrant to the extent that, after giving effect to the exercise, such holder (together with its affiliates and any other persons acting as a group together with such holder) would beneficially own more than 4.99% (or, at the election of the holder at the time of issuance, 9.99%) of the outstanding shares of our common stock. A holder may increase or decrease this limitation upon 61 days’ prior notice to us. However, holder of a Pre-Funded Warrant may not exercise the warrant to the extent that, after giving effect to the exercise, such holder (together with its affiliates and any other persons acting as a group together with such holder) would beneficially own more than 19.99% of the outstanding shares of our common stock, which beneficial ownership limitation may not be amended or waiver by the hold or the Company unless and until stockholder approval is obtained in accordance with Nasdaq Listing Rule 5635(b).
Delaware Anti-Takeover Statute
We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, Section 203, subject to certain exceptions, prohibits a publicly held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that such person or entity became an interested stockholder, unless:
7

Table of Contents
•     prior to such date, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
•     upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding specified shares; or
•     at or subsequent to such date of the transaction that resulted in a person or entity becoming an interested stockholder, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 662∕3% of the outstanding voting stock that is not owned by the interested stockholder.
The application of Section 203 may limit the ability of stockholders to approve a transaction that they may deem to be in their best interests. In addition, Section 203 makes it more difficult for an interested stockholder to effect various business combinations with a corporation for a three-year period, although the stockholders may, by adopting an amendment to our Certificate of Incorporation or Bylaws, elect not to be governed by this section, effective 12 months after adoption.
In general, Section 203 defines “business combination” as:
•     any merger or consolidation involving the corporation and the interested stockholder;
•     any sale, lease, exchange, mortgage, pledge, transfer or other disposition of 10% or more of the assets of the corporation to or with the interested stockholder;
•     subject to certain exceptions, any transaction which results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
•     any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or
•     the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.
In general, Section 203 defines an “interested stockholder” as any person that is:
•     the owner of 15% or more of the outstanding voting stock of the corporation;
•     an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the relevant date; or
•     an affiliate or associate of the above.
Our Certificate of Incorporation and Bylaws do not exclude us from the restrictions imposed under Section 203. We anticipate that the provisions of Section 203 may encourage companies 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 resulted in the stockholder becoming an interested stockholder.
Other Corporate Governance Matters
Under our Certificate of Incorporation, directors shall be elected for a one-year term expiring at the next annual meeting. Directors elected to succeed those directors whose terms then expire shall be elected for a term of office to expire at the succeeding annual meeting after their election, with each director to hold office until his or her successor shall have been duly elected and qualified.

Table of Contents
Subject to the preferential rights of any other class or series of preferred stock, any director, or the entire Board, may be removed from office at any time, with or without cause, by the affirmative vote of the holders of a majority of the voting power of all the then outstanding shares of voting stock of the Company, voting together as a single class. Our Bylaws require that stockholders provide the Secretary of our company with notice of the nomination of a person for election as a director with respect to an election to be held at an annual meeting of stockholders, not less than 90 nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting of stockholders or special meeting in lieu of an annual meeting, provided, however, that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be given, not earlier than the 120th day prior to such annual meeting and not later than the 90th day prior to such annual meeting or, if later, the 10th day following the day on which public disclosure of the date of such annual meeting was first made. To be timely, a stockholder’s notice for nominations to be made at a special meeting must be made not earlier than the 120th day prior to such special meeting and not later than the 90th day prior to such special meeting or, if later, the 10th day following the day on which public disclosure of the date of such special meeting was first made. Our Bylaws provide that special meetings of stockholders of our company may be called only by: (i) the Chairman of the Board, (ii) by a majority of the Board, or (iii) the Chief Executive Officer of our Company. Our Certificate of Incorporation, as well as applicable provisions of the DGCL, provide that no action required or permitted to be taken at any annual or special meeting of our stockholders may be taken without a meeting, unless the consent of two-thirds of the voting power of the then outstanding shares of stock of the company entitled to vote on the matter is obtained. These provisions may diminish the likelihood that a potential acquirer would make an offer for our common stock or that there would otherwise be a change in control of our company.
Transfer Agent and Registrar
The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.. The transfer agent’s address is 462 South 4th Street, Louisville, Kentucky 40202.

SELLING STOCKHOLDERS
The Selling Stockholders may sell some, all or none of their shares. We do not know how long the Selling Stockholders will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the Selling Stockholders regarding the sale or other disposition of any of the shares. The shares covered hereby may be offered from time to time by the Selling Stockholders. As a result, we cannot estimate the number of shares of common stock the Selling Stockholders will beneficially own after termination of sales under this prospectus. In addition, the Selling Stockholders may have sold, transferred or otherwise disposed of all or a portion of their shares of common stock since the date on which they provided information for the table below.
Information regarding each additional Selling Stockholder, if any, will be set forth by a prospectus supplement to the extent required prior to the time of any offer or sale of such Selling Stockholder’s shares pursuant to this prospectus. Any prospectus supplement may add, update, substitute, or change the information contained in this prospectus, including the identity of each Selling Stockholder and the number of shares registered on its behalf. A Selling Stockholder may sell or otherwise transfer all, some or none of such shares in this offering. See “Plan of Distribution.”
Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to our common stock. Generally, a person “beneficially owns” shares of our common stock if the person has or shares with others the right to vote those shares or to dispose of them, or if the person has the right to acquire voting or disposition rights within 60 days.
The information in the table below and the footnotes thereto regarding shares of common stock to be beneficially owned after the offering assumes the sale of all shares being offered by the Selling Stockholders under this prospectus. This information has been obtained from the Selling Stockholders. The percentage of shares owned after the offering is based on 93,744,210 shares of common stock outstanding as of October 7, 2026. In computing the number of shares of common stock beneficially owned by a Selling Stockholder and the percentage ownership of that Selling Stockholder, we deemed outstanding shares of common stock subject to Pre-Funded Warrants or other options, warrants or convertible securities held by that Selling Stockholder that are currently exercisable or exercisable within 60 days of October 7, 2026. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other Selling Stockholder.
Except for the ownership of shares of our common stock and Pre-Funded Warrants issued pursuant to the Purchase Agreement and the registration rights granted pursuant to the Registration Rights Agreement, none of the Selling Stockholders has had any material relationship with us or any of our predecessors or affiliates within the past three years. None of the Selling Stockholders is a broker-dealer or an affiliate of a broker-dealer.

PLAN OF DISTRIBUTION
Each Selling Stockholder of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on any stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:
•     ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
•     block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
•     purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
•     an exchange distribution in accordance with the rules of the applicable exchange;
•     privately negotiated transactions;
•     settlement of short sales;
•     in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;
•     through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
•     a combination of any such methods of sale; or
•     any other method permitted pursuant to applicable law.
The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.
Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.
In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
We agreed to keep the registration statement of which this prospectus is a part effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and

The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.
Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the shares of common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the shares of common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Item 15.   Indemnification of Directors and Officers.
Under Section 145 of the DGCL, we have broad powers to indemnify our directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act. Section 145 of the DGCL generally provides that a Delaware corporation has the power to indemnify its present and former directors, officers, employees and agents against expenses incurred by them in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in or not opposed to, the best interests of the corporation and, with respect to any criminal action, they had reasonable cause to believe their conduct was lawful.
Our Restated Certificate of Incorporation, as amended from time to time (the “Certificate of Incorporation”) includes provisions that (i) limit the personal liability of our current and former directors, officers, employees and agents for monetary damages resulting from breaches of their fiduciary duty to the fullest extent permitted under applicable law, (ii) require us to indemnify our directors, officers, employees and agents to the fullest extent permitted by the DGCL or other applicable law, (iii) upon satisfaction of certain conditions, we are required to advance expenses incurred by a director in advance of the final disposition of any action or proceeding and (iv) permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law.
We believe that these provisions of the Certificate of Incorporation and Amended and Restated Bylaws, as amended from time to time, are necessary to attract and retain qualified persons as directors and officers. These provisions do not eliminate our directors’ or officers’ duty of care, and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under the DGCL. In addition, each director will continue to be subject to liability pursuant to Section 174 of the DGCL, for breach of such director’s duty of loyalty to us, for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for acts or omissions that such director believes to be contrary to our best interests or the best interests of our stockholders, for any transaction from which such director derived an improper personal benefit, for acts or omissions involving a reckless disregard for such director’s duty to us or to our stockholders when such director was aware or should have been aware of a risk of serious injury to us or to our stockholders, for acts or omission that constitute an unexcused pattern of inattention that amounts to an abdication of such director’s duty to us or to our stockholders, for improper transactions between such director and us and for improper loans to directors and officers. Under Section 102(b)(7) of the DGCL, as amended, the limitation of liability for officers does not apply to (i) any breach of the duty of loyalty to the corporation or its stockholders, (ii) any acts or omissions not in
17

Table of Contents
good faith or which involve intentional misconduct or a knowing violation of law, (iii) any transaction from which the officer derived an improper personal benefit, or (iv) any action by or in the right of the corporation. These provisions also do not affect a director’s or officer’s responsibilities under any other law, such as the federal securities law or state or federal environmental laws.
As permitted by Delaware law, we have entered into indemnification agreements with each of our current directors and executive officers pursuant to the foregoing provisions. We also maintain customary directors’ and officers’ liability insurance.

Item 17.   Undertakings.
The undersigned registrant hereby undertakes:
(a)   (1)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)   To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii)   To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end
18

Table of Contents
of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC, pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” in the effective registration statement; and
(iii)   To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
Provided, however, that the undertaking set forth in paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement, or are contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.
(2)   That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)   To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)   That, for the purpose of determining liability under the Securities Act to any purchaser:
(i)   Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(ii)   Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(b)   That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)   Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant

has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person of the registrant in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: NN,Inc. Registration Statement on Form S-3

Ladies and Gentlemen:

In our capacity as special counsel to NN, Inc. a Delaware corporation (the “Company”), we have been asked to render this opinion in connection with a Registration Statement (the “Registration Statement”) on Form S-3 filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), covering the resale of up to an aggregate of 16,100,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), consisting of (i) 11,275,605 shares of Common Stock (the “Shares”) and (ii) 4,824,395 shares of Common Stock issuable upon the exercise of pre-funded warrants (the “Pre-Funded Warrants” and shares of Common Stock underlying the Pre-Funded Warrants, the “Pre-Funded Warrant Shares” and together with the Shares, the “Shares”). The Shares and the Pre-Funded Warrants were issued pursuant to a Securities Purchase Agreement, dated October 1, 2026 by and among the Company and the purchasers named therein (the “Purchase Agreement”).
 
We are delivering this opinion to you at your request in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.
 
In connection with rendering this opinion, we have examined and are familiar with the Company’s (i) certificate of incorporation and bylaws, each as amended and restated; (ii) the Registration Statement, including the Prospectus; (iii) corporate proceedings of the Company relating to the issuance of the securities described herein; (iv) the Purchase Agreement, (v) the Pre-Funded Warrants, and (vi) such other instruments and documents as we have deemed relevant under the circumstances.
 
In making the aforesaid examinations, we have assumed the genuineness of all signatures and the conformity to original documents of all copies furnished to us as original or photostatic copies. We have also assumed that the corporate records furnished to us by the Company include all corporate proceedings taken by the Company to date. We have assumed without investigation that there has been no relevant change or development between the dates as of which the information cited in the preceding sentence was given and the date of this letter. As to certain factual matters, we have relied upon a certificate of officers of the Company and have not sought to independently verify such matters.
 
Based upon the foregoing, and in reliance thereon, and subject to the qualifications, limitations and exceptions stated herein, we are of the opinion, having due regard for such legal considerations as we deem relevant, that:

1.the Shares are validly issued, fully paid and nonassessable; and

2.the Pre-Funded Warrant Shares when issued in accordance with the Pre-Funded Warrants, will be validly issued, fully paid and nonassessable.
