To Our Stockholders,

Twenty-five years ago, we founded nLIGHT with the vision that semiconductor lasers would improve at a rapid rate and enable important new applications. We have worked relentlessly and deliberately to expand our vertically integrated U.S. based manufacturing to support our vision and today we are stronger than ever across our technology stack from leading semiconductor laser devices to our record 300 kilowatt coherently beam combined laser. Our vision remains the same and our mission has never been more consequential.

**Looking Back \|** Strong Growth and Expanding Leverage in 2025

We reported exceptional financial results in 2025 with full-year revenue of $261 million, an increase of 32% year-over-year. Record aerospace and defense revenue of $175 million grew 60% year-over-year, driven by strong execution on existing programs, successful production ramps, and new contract awards that provide clear visibility into continued growth.

Our accelerated top-line growth also drove significant improvements in bottom-line performance. In 2025, gross margins expanded to 30%, up from 17% in 2024; and operating cash flow increased to $21 million, up from negative $2.4 million in 2024. These results demonstrate the operating leverage inherent in our model as scale increases.

**Our Mission \|** Vertically integrated technology focused on national security

Our results in 2025 not only validated our long-standing vision but also provided heightened importance to our mission: ensuring that our vertically integrated U.S. based technology stack is aligned to support the critical technologies essential to national security in a more contested world.

We are in the midst of a multi-generational shift. The post–Cold War order that shaped global commerce, security, and innovation is giving way to sustained great-power competition and the weaponization of technology. We can no longer rely on legacy technologies alone. We are investing across every layer of our technology stack to deliver operational capability in next-generation high-power lasers to the United States and its allies.

**Our Strategy \|** focus on three critical technology areas

The U.S. government's list of critical technology areas provides clear reinforcement of our mission and focus. Within that framework, we are concentrated on three areas where our vertically integrated technology stack is meaningfully differentiated:

**1. Directed Energy** 

nLIGHT is uniquely positioned for directed energy lasers through more than two decades of investment in industry-leading, vertically integrated high-power laser technology. Our capabilities span the full stack—from chips and components to coherent beam-combined lasers and complete laser weapon modules, including beam directors and atmospheric correction. We believe that scaling output to hundreds of kilowatts using coherent-combined architectures with fast adaptive wavefront control is essential to provide effective defensive capability against advanced threats. In 2025, we made significant progress integrating and testing a 50 kW laser weapon module for the Army's DE M-SHORAD program, packaging our 300 kW laser for field testing against advanced threats, and we remain on track to scale to 1 megawatt under the Office of the Undersecretary of War for Research and Engineering (OUSW R&E) HELSI program.

**2. Laser Sensing**

We have a long track record of delivering highly reliable lasers and subsystems for precision guidance and threat detection. Our laser sensing portfolio supports missile guidance, proximity detection, ranging, and countermeasures, and is embedded in multiple long-running defense programs. We believe these applications will continue to grow for years to come, supported by ongoing development of advanced lasers for mission-critical systems.

**3. Advanced Manufacturing**

Our high-power lasers, combined with proprietary beam-shaping technology, enable partners to manufacture metal parts more efficiently and effectively through additive manufacturing processes. In 2025, we made a deliberate shift to focus exclusively on additive manufacturing and exit commoditized cutting and welding markets. Additive manufacturing is increasingly vital for space, defense, and industrial applications, and adoption of this critical capability is accelerating.

**Looking Ahead \|** Launching new products and scaling operations

We enter 2026 with $162 million in funded backlog. Early in 2026, we strengthened the balance sheet with a follow-on offering that generated $200 million of gross proceeds to accelerate new product launches, expand U.S. manufacturing capacity, and strengthen our supply chain.

Our priorities are clear: launch new high-power lasers into funded production programs with U.S. customers and allies; scale U.S. manufacturing with the quality and delivery rigor our partners depend on; de-risk critical components and deepen our domestic supply chain with key partners; and expand nLIGHT lasers across directed energy, sensing, and advanced manufacturing.

Our objective is straightforward: to build a durable, profitable company focused on the critical technologies essential to our nation.

**Our Mandate \|** Maintain urgency and remain vigilant

A quarter century after founding nLIGHT, it is deeply rewarding to reflect on our leadership in high-power laser technologies that both create shareholder value and serve national priorities. Our technology stack has never been stronger. We are addressing pressing challenges in a rapidly changing world. The moment has never demanded more of us.

We are optimistic about what lies ahead. We are also clear-eyed. The world that shaped the previous decades is gone. The world we now serve demands the same urgency that guided us at our founding yet with greater vigilance.

I am proud of our employees, grateful for your trust, and energized by the important work ahead.

**nLIGHT, INC.**

**PROXY STATEMENT FOR 2026 ANNUAL MEETING OF STOCKHOLDERS To Be Held at 9:00 a.m. Pacific Time on Friday, June 5, 2026** 

We are furnishing this proxy statement and the enclosed form of proxy in connection with a solicitation of proxies by our board of directors for use at the 2026 annual meeting of stockholders of nLIGHT, Inc., a Delaware corporation (the "Company"), and any postponements, adjournments or continuations thereof (the "Annual Meeting"). The Annual Meeting will be held virtually on Friday, June 5, 2026, at 9:00 a.m., Pacific Time. You can attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/LASR2026, where you will be able to listen to the meeting live, submit questions and vote online. The Notice of Internet Availability of Proxy Materials (the "Notice") containing instructions on how to access this proxy statement and our annual report is first being mailed on or about April 24, 2026, to all stockholders entitled to vote at the Annual Meeting.

The information provided in the "question and answer" format below is for your convenience only and is merely a summary of the information contained in this proxy statement. You should read this entire proxy statement carefully. Information contained on, or that can be accessed through, our website is not intended to be incorporated by reference into this proxy statement and references to our website address in this proxy statement are inactive textual references only.

**THE PROXY PROCESS AND STOCKHOLDER VOTING: <br>QUESTIONS AND ANSWERS**

**What matters am I voting on?**

You will be voting on:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the election of the one Class II director nominee who is named in the accompanying proxy statement to serve until our 2029 annual meeting of stockholders and until his respective successor is duly elected and qualified;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a proposal to ratify the appointment of KPMG LLP ("KPMG") as our independent registered public accounting firm for our fiscal year ending December 31, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a proposal to approve, on an advisory, non-binding basis, the compensation of our named executive officers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other business as may properly come before the Annual Meeting.

**How does the Board of Directors recommend I vote on these proposals?**

Our board of directors recommends a vote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "FOR" the election of Geoffrey Moore as a Class II director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "FOR" the ratification of the appointment of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "FOR" the approval, on an advisory, non-binding basis, of the compensation of our named executive officers.

**Who is entitled to vote?** 

Holders of our common stock as of the close of business on April 6, 2026, the record date for the Annual Meeting, may vote at the Annual Meeting. As of the record date, there were 56,406,459 shares of our common stock outstanding. Our common stock will vote as a single class on all matters described in this proxy statement for which your vote is being solicited. Stockholders are not permitted to cumulate votes with respect to the election of directors. Each share of common stock outstanding as of the record date is entitled to one vote.

*Registered Stockholders*. If your shares are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares and we provided the Notice to you directly. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or vote virtually at the Annual Meeting. Throughout this proxy statement, we refer to these registered stockholders as "stockholders of record."

*Street Name Stockholders*. If your shares are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in "street name," and the Notice was forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to attend the Annual Meeting. However, since a beneficial owner is not the stockholder of record, you may not vote your shares of our common stock virtually at the Annual Meeting unless you follow your broker's procedures for obtaining a legal proxy. If you request a printed copy of our proxy materials by mail, your broker, bank or other nominee will provide a voting instruction form for you to use. Throughout this proxy statement, we refer to stockholders who hold their shares through a broker, bank or other nominee as "street name stockholders."

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

**Is there a list of registered stockholders entitled to vote at the Annual Meeting?**

A list of registered stockholders entitled to vote at the Annual Meeting will be made available for examination by any stockholder for any purpose germane to the meeting for a period of at least ten days prior to the meeting between the hours of 9:00 a.m. and 5:00 p.m., Pacific Time, at our principal executive offices located at 4637 NW 18<sup>th</sup> Avenue, Camas, Washington 98607 by contacting our corporate secretary.

**How many votes are needed for approval of each proposal?**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Proposal No. 1*: The election of directors requires a plurality of the voting power of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. "Plurality" means that the nominees who receive the largest number of votes cast "FOR" are elected as directors. As a result, any shares not voted "FOR" a particular nominee (whether as a result of stockholder abstention or a broker non-vote (as defined below)) will not be counted in such nominee's favor and will have no effect on the outcome of the election. You may vote "FOR" or "WITHHOLD" on the nominee for election as a director.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Proposal No. 2*: The ratification of the appointment of KPMG requires the affirmative vote of a majority of the voting power of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions are considered votes present and entitled to vote on this proposal, and thus will have the same effect as a vote "AGAINST" the proposal. Broker non-votes will have no effect on the outcome of this proposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Proposal No. 3*: The advisory non-binding vote to approve the fiscal 2025 compensation of our named executive officers requires the affirmative vote of a majority of the voting power of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions are considered votes present and entitled to vote on this proposal, and thus will have the same effect as a vote "AGAINST" the proposal. Broker non-votes will have no effect on the outcome of this proposal. Because this vote is advisory only, it will not be binding on us, our board of directors or our compensation committee. Instead, our board of directors and our compensation committee will consider the outcome of the vote when determining the compensation of our named executive officers.

**What is a quorum?**

A quorum is the minimum number of shares required to be present at the Annual Meeting for the meeting to be properly held under our amended and restated bylaws (the "bylaws") and Delaware law. The virtual presence or representation by proxy of a majority of all issued and outstanding shares of common stock entitled to vote at the Annual Meeting will constitute a quorum at the meeting. A proxy submitted by a stockholder may indicate that all or a portion of the shares represented by the proxy are not being voted ("stockholder withholding") with respect to a particular matter. Similarly, a broker may not be permitted to vote stock ("broker non-vote") held in street name on a particular matter in the absence of instructions from the beneficial owner of the stock. See "How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?" The shares subject to a proxy that are not being voted on a particular matter because of either stockholder withholding or broker non-vote will count for purposes of determining the presence of a quorum. Abstentions are also counted in the determination of a quorum.

**How do I vote?**

If you are a stockholder of record, there are four ways to vote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;by Internet at www.proxyvote.com, 24 hours a day, seven days a week, until 11:59 p.m. Eastern Time on June 4, 2026 (have your Notice or proxy card in hand when you visit the website);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;by toll-free telephone at 1-800-690-6903 (have your Notice or proxy card in hand when you call), until 11:59 p.m. Eastern Time, on June 4, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;by completing and mailing your proxy card (if you received printed proxy materials) to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;by attending the Annual Meeting by visiting www.virtualshareholdermeeting.com/LASR2026, where stockholders may vote and submit questions during the meeting (have your Notice or proxy card in hand when you visit the website). Beneficial owners must obtain a legal proxy from their broker, bank or other nominee to vote during the meeting. Follow the instructions from your broker, bank or other nominee included with the Notice, or contact your broker, bank or other nominee, to request a legal proxy. All votes must be received by the inspector of elections before the polls close during the meeting.

Even if you plan to attend the Annual Meeting, we recommend that you also vote by proxy so that your vote will be counted if you later decide not to attend the Annual Meeting.

If you are a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to instruct your broker, bank or other nominee on how to vote your shares. Street name stockholders should generally be able to vote by returning an instruction card, or by telephone or on the Internet. However, the availability of telephone and Internet voting will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a street name stockholder, you may not vote your shares virtually at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

**Can I change my vote?**

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy any time before the Annual Meeting by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;entering a new vote by Internet or by telephone;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;completing and mailing a later-dated proxy card;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;notifying the corporate secretary of nLIGHT, Inc., in writing, at nLIGHT, Inc., Attn: Corporate Secretary, 4637 NW 18<sup>th</sup> Avenue, Camas, Washington 98607; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy). A stockholder's last vote is the vote that will be counted.

If you are a street name stockholder, your broker, bank or other nominee can provide you with instructions on how to change your vote.

**What do I need to do to attend the virtual Annual Meeting?**

You will be able to attend the Annual Meeting online, submit your questions during the meeting and vote your shares electronically at the meeting by visiting www.virtualshareholdermeeting.com/LASR2026. To participate in the Annual Meeting, you will need the control number included on your Notice or proxy card. The Annual Meeting webcast will begin promptly at 9:00 a.m. Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 8:45 a.m. Pacific Time, and you should allow ample time for the check-in procedures.

**How can I get help if I have trouble checking in or listening to the Annual Meeting online?**

If you encounter difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual meeting log-in page.

**What is the effect of giving a proxy?**

Proxies are solicited by and on behalf of our board of directors. Scott Keeney and Joseph Corso with full power of substitution and re-substitution have been designated as proxy holders by our board of directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors as described above. If any matters not described in this proxy statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned, the proxy holders can vote the shares on the new Annual Meeting date as well, unless you have properly revoked your proxy instructions, as described above.

**Who will count the votes?**

Julie Dimmick, our general counsel and corporate secretary, will tabulate the votes and act as inspector of elections.

**How can I contact nLIGHT's transfer agent?**

You may contact our transfer agent, Computershare Inc., by telephone at (800) 736-3001, or by writing Computershare via regular mail at P.O. Box 43078, Providence, RI 02940-3078, or via overnight/certified/registered delivery at 150 Royall Street, Suite 202, Canton, MA 02021. You also may also access instructions with respect to certain stockholder matters (e.g., change of address) via the Internet at www.computershare.com/investor.

**Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?**

In accordance with the rules of the Securities and Exchange Commission ("SEC"), we have elected to furnish our proxy materials, including this proxy statement and our annual report, primarily via the Internet. The Notice containing instructions on how to access our proxy materials is first being mailed on or about April 24, 2026, to all stockholders entitled to vote at the Annual Meeting. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials on the Internet to help reduce the environmental impact and cost of our annual meetings of stockholders.

**How do we solicit proxies for the Annual Meeting?**

Our board of directors is soliciting proxies for use at the Annual Meeting. We will bear all expenses associated with this solicitation. We will reimburse brokers or other nominees for reasonable expenses that they incur in sending our proxy materials to you if a broker, bank or other nominee holds your shares. In addition, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Our directors and employees will not be paid any additional compensation for soliciting proxies.

**How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?**

If you hold your shares in street name, you will need to follow the instructions your broker provides to instruct your broker on how to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to "routine" items, but not with respect to "non-routine" items. The ratification of the appointment of KPMG as our independent registered public accounting firm for the year ending December 31, 2026 (Proposal No. 2) is considered to be routine under applicable rules. Since a broker or other nominee may generally vote on routine matters, no broker non-votes are expected to exist in connection with this

------

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

proposal. The election of the Class II director (Proposal No. 1) and the advisory non-binding vote to approve the compensation of our named executive officers (Proposal No. 3) are considered "non-routine" under applicable federal securities rules. Absent direction from you, your broker will not have discretion to vote on these non-routine matters, and therefore there may be broker non-votes in connection with these proposals.

**Where can I find the voting results of the Annual Meeting?**

We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four business days after the Annual Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to the Current Report on Form 8-K after they become available.

**I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?**

We have adopted a procedure called "householding," which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, our proxy materials, to multiple stockholders who share the same address unless we have received contrary instructions from one or more of the stockholders. This procedure reduces our printing costs, mailing costs, and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice and, if applicable, our proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these materials. To receive a separate copy, or, if a stockholder is receiving multiple copies, to request that we only send a single copy of the Notice and, if applicable, our proxy materials, such stockholder may contact us at the following:

nLIGHT, Inc.

Attention: Corporate Secretary

4637 NW 18<sup>th</sup> Avenue

Camas, Washington 98607

Tel: (360) 566-4460

Street name stockholders may contact their broker, bank or other nominee to request information about householding.

**What is the deadline to propose actions for consideration at next year's annual meeting of stockholders or to nominate individuals to serve as directors?**

*Stockholder Proposals*

Stockholders may present proper proposals for inclusion in our proxy statement and for consideration at the next annual meeting of stockholders by submitting their proposals in writing to our corporate secretary in a timely manner. For a stockholder proposal to be considered for inclusion in our proxy statement for our 2027 annual meeting of stockholders, our corporate secretary must receive the written proposal at our principal executive offices not later than December 25, 2026. In addition, stockholder proposals must comply with the requirements of Rule 14a-8 regarding the inclusion of stockholder proposals in company-sponsored proxy materials. Stockholder proposals should be addressed to:

nLIGHT, Inc.

Attention: Corporate Secretary

4637 NW 18<sup>th</sup> Avenue

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

Our bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our proxy statement. Our bylaws provide that the only business that may be conducted at an annual meeting of stockholders is business that is (1) specified in our notice of annual meeting (or any supplement thereto) with respect to such meeting, (2) otherwise properly brought before such meeting by or at the direction of our board of directors, or any committee thereof that has been formally delegated authority to propose such business pursuant to a resolution adopted by the affirmative vote of a majority of the total number of authorized directors whether or not there exist any vacancies or other unfilled seats, or (3) properly brought before such meeting by a stockholder who is a stockholder of record (i) at the time of the giving of the advance notice, (ii) on the record date for the determination of stockholders entitled to notice of the annual meeting, (iii) on the record date for the determination of stockholders entitled to vote at the annual meeting, (iv) at the time of the annual meeting and (v) who has timely complied in proper written form with the notice procedures specified in our bylaws. To be timely for our 2027 annual meeting of stockholders, our corporate secretary must receive the written notice at our principal executive offices:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;not earlier than 8:00 a.m., Pacific time, on February 8, 2027; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;not later than 5:00 p.m., Pacific time, on March 10, 2027.

In the event that we hold our 2027 annual meeting of stockholders more than 25 days from the one-year anniversary of the Annual Meeting, notice of a stockholder proposal that is not intended to be included in our proxy statement must be received no earlier than 8:00 a.m., Pacific time, on the 120th day before our 2027 annual meeting of stockholders and no later than 5:00 p.m., Pacific time, on the later of the following two dates:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the 90th day prior to our 2027 annual meeting of stockholders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the 10th day following the day on which public announcement of the date of our 2027 annual meeting of stockholders is first made.

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting does not appear to present his, her or its proposal at such annual meeting, we are not required to present the proposal for a vote at the annual meeting.

*Recommendation and Nomination of Director Candidates*

**Director Independence**

Under the rules of the Nasdaq Stock Market, independent directors must comprise a majority of a listed company's board of directors. In addition, the rules of the Nasdaq Stock Market require that, subject to specified exceptions, each member of a listed company's audit, compensation and nominating and corporate governance committees must be independent. Under the rules of the Nasdaq Stock Market, a director will only qualify as an "independent director" if, in the opinion of that company's board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

------

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. To be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (ii) be an affiliated person of the listed company or any of its subsidiaries.

Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of our directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Our board of directors considered relationships and all other facts and circumstances deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director. In connection with its review and determination that Ms. Nichols is not independent, our board of directors considered Ms. Nichols' employment as Interim President of nLIGHT DEFENSE Systems, Inc., our wholly owned subsidiary, from April 2024 through December 2024.

There are no family relationships among any of our directors or executive officers.

Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined the following:

---

| | |
|:---|:---|
| **Directors** | **Status** |
| Scott Keeney | Not independent |
| Bandel Carano<sup>(1)</sup> | Independent |
| Bill Gossman | Independent |
| Gerald Haines | Independent |
| Mark Hartman | Independent |
| Raymond Link<sup>(1)</sup> | Independent |
| Gary Locke | Independent |
| Geoffrey Moore | Independent |
| Camille Nichols | Not independent |

---

<u>&nbsp;&nbsp;&nbsp;&nbsp;</u> 

<sup>(1)</sup> Messrs. Carano and Link are not standing for reelection and will cease to be members of our board of directors at the expiration of their terms at the Annual Meeting. Consequently, the size of our board of directors will be seven directors as of the Annual Meeting.

**Board Leadership Structure**

Scott Keeney, our president and chief executive officer, is also the chairman of our board of directors. Our board of directors has determined that having our principal executive officer also serve as the chairman of our board of directors, along with having a lead independent director, provides us with optimally effective leadership and is in the best interests of our company and stockholders. Mr. Keeney founded and has led our company since its inception. Our board of directors believes that Mr. Keeney's strategic vision for our business, his in-depth knowledge of our products, the laser industry and his experience serving as our president and chief executive officer since our inception make him well qualified to serve as chairman of our board.

The role given to the lead independent director helps ensure a strong independent and active board of directors. Our board of directors has appointed Bill Gossman to serve as our lead independent director. As lead independent director, Mr. Gossman presides over periodic meetings of our independent directors, serves as a liaison between the chairperson of our board of directors and the independent directors and performs

such additional duties as our board of directors may otherwise determine and delegate. Our corporate governance guidelines limit the service of our lead independent director to three years from the date of appointment unless the board of directors otherwise determines that continued service for more than three years would be in the best interests of our company and our stockholders.

**Executive Sessions of Non-Employee Directors**

In order to encourage and enhance communication among non-employee directors, and as required under the applicable rules of the Nasdaq Stock Market, our corporate governance guidelines provide that the non-employee directors of our board of directors will meet in executive sessions without management directors or company management present on a periodic basis, but no less than twice a year.

**Board and Committee Meetings**

During 2025, our board of directors held seven meetings (including regularly scheduled and special meetings), and no director attended less than 75% of the aggregate of (1) the total number of meetings of our board of directors held during the period for which he or she has been a director and (2) the total number of meetings held by all committees of our board of directors during the periods that he or she served on those committees.

Although we do not have a formal policy regarding attendance by members of our board of directors at annual meetings of stockholders, we encourage our directors to attend. Eight of our directors who served at the time of the prior year's annual meeting of stockholders attended such meeting.

Our board of directors has an audit committee, a compensation committee, a nominating and corporate governance committee, and an information and technology security committee, each of which has the composition and the responsibilities described below as of the date of this proxy statement. Members serve on these committees until their resignation or until as otherwise determined by our board of directors. Messrs. Carano and Link are not standing for reelection and will cease to be members of our board of directors at the expiration of their terms at the Annual Meeting. Following the Annual Meeting, the board of directors will reconstitute the composition of its committees as appropriate to ensure continued compliance with applicable SEC rules and the rules of the Nasdaq Stock Market.

Some of the qualifications that our nominating and corporate governance committee considers include, without limitation, issues of character, integrity, judgment, diversity, age, independence, skills, education, expertise, business acumen, business experience, length of service, understanding of our business, other commitments and the like. Other than the foregoing, there are no stated minimum criteria for director nominees.

Our board of directors believes that our board should be a diverse body. Although our board of directors does not maintain a specific policy with respect to board diversity, our corporate governance guidelines provide that the nominating and corporate governance committee may consider diversity, with respect to professional background, education, race, ethnicity, gender, age and geography, as one factor in assessing director candidate qualifications. Our nominating and corporate governance committee also considers these and other factors as it oversees the annual board of directors and committee evaluations.

Our nominating and corporate governance committee evaluates additional director candidates from time to time using the criteria discussed above to identify qualified candidates. When qualified candidates are identified, we may appoint such candidates to vacancies on our board of directors separate from the election of directors by our stockholders at our annual meetings. Any vacancies on the board of directors occurring between our annual meetings of stockholders may be filled by persons selected by a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and any director so elected will serve for the remaining term of the class of directors in which the vacancy occurred.

**Stockholder Recommendations for Nominations to the Board of Directors**

The nominating and corporate governance committee will consider candidates for directors recommended by stockholders so long as such recommendations comply with the certificate of incorporation and bylaws of our company and applicable laws, rules and regulations including those promulgated by the SEC. The committee will evaluate such recommendations in accordance with its charter, our bylaws, and the regular nominee

criteria described above. This process is designed to ensure that the board of directors includes members with diverse backgrounds, skills and experiences, including appropriate financial and other expertise relevant to our business. Eligible stockholders wishing to recommend a candidate for nomination should contact our corporate secretary in writing. Such recommendations must include information about the candidate, a statement of support by the recommending stockholder, evidence of the recommending stockholder's ownership of our stock and a signed letter from the candidate confirming willingness to serve on our board of directors. The committee has discretion to decide which individuals to recommend for nomination as directors.

A stockholder of record can nominate a candidate directly for election to the board of directors by complying with the procedures in Section 2.4 of our bylaws. Any eligible stockholder who wishes to submit a nomination should review the requirements in the bylaws on nominations by stockholders. Any nomination for our 2027 annual meeting should be sent in writing to nLIGHT, Inc., Attention: Corporate Secretary, 4637 NW 18th Avenue, Camas, Washington 98607. To be timely for our 2027 annual meeting, nominations must be received observing the deadlines set forth above under "The Proxy Process and Stockholder Voting: Questions and Answers—What is the deadline to propose actions for consideration at next year's annual meeting of stockholders or to nominate individuals to serve as directors?"

**Communications with the Board of Directors**

The board of directors believes that management speaks for our company. Individual directors may, from time to time, meet or otherwise communicate with various constituencies that are involved with our company, but it is expected that directors would do this with knowledge of management and, in most instances, only at the request of management.

In cases where stockholders wish to communicate directly with the non-management directors, messages can be sent by mail to the attention of our corporate secretary at 4637 NW 18th Avenue, Camas, Washington 98607. We will forward such communications, as appropriate, to the appropriate member(s) of the board of directors or, if none is specified, to the chairperson or lead independent director, as applicable.

**Corporate Governance Guidelines and Code of Business Conduct and Ethics**

Our board of directors has adopted corporate governance guidelines that address items such as the qualifications and responsibilities of our directors and director candidates, including independence standards, and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The full text of our corporate governance guidelines and our code of business conduct and ethics is posted on our website, https://investors.nlight.net/governance/. The information on, or that can be accessed through, our website is not part of this filing. We intend to disclose any amendments to the code of business conduct and ethics, or any waivers of its requirements, on our website to the extent required by the applicable rules and exchange requirements.

**Insider Trading Policy**

Our board of directors has adopted an insider trading policy that governs the purchase, sale and other dispositions of our securities by directors, officers, employees and other covered persons that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations, and applicable stock exchange listing requirements. A copy of our insider trading policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025. In addition, with regard to trading in our own securities, it is our policy to comply with the federal securities laws and the applicable exchange listing requirements.

**Stockholder Engagement**

We maintain active, year-round engagement with our stockholders and regularly discuss a variety of topics, including but not limited to our financial and operating performance, our business and growth strategy, governance matters and executive compensation. We value the insights and feedback we gather from these engagements, which help inform board decisions. We believe our engagement program provides stockholders with an effective channel for two-way dialogue with both our board of directors and management.

**Risk Management**

Our board of directors plays an active role, as a whole and also at the committee level, in overseeing the management of our risks. The board of directors is responsible for general oversight of risks and regular review of information regarding our risks. The audit committee is responsible for the initial review and oversight of risk assessment and risk management for the company, as well as overseeing the management of risks relating to accounting matters, financial reporting and potential conflicts of interest. The compensation committee is responsible for overseeing the management of risks relating to our compensation philosophy and practices applicable to executives and all employees. The information and technology security committee is responsible for overseeing the management of risks relating to the physical and cyber security of our information, intellectual property, personnel, and facilities. The nominating and corporate governance committee is responsible for overseeing the management of risks relating to our corporate governance practices, the independence of the board of directors and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire board of directors is regularly informed through discussions from committee members about such risks. The board of directors believes its administration of its risk oversight function has not affected the board of directors' leadership structure.

**Outside Director Compensation Policy**

Our board of directors approved compensation to our non-employee directors under our outside director compensation policy, which was adopted by our board of directors in connection with our initial public offering, in consultation with an independent compensation consultant, and most recently amended effective April 1, 2026. The compensation committee periodically reviews the type and form of compensation paid to our non-employee directors. As part of this review, the compensation committee analyzes non-employee director compensation trends and data from companies comprising the same executive compensation peer group used by the compensation committee in connection with its review of executive compensation.

Under our outside director compensation policy as in effect for 2025 and through March 31, 2026, non-employee directors received compensation in the form of equity and cash, as described below:

In addition to the cash compensation structure described above, our outside director compensation policy provides for the following equity incentive compensation program for non-employee directors:

*Election to Receive RSUs in lieu of Cash Retainers.* Subject to the limits under our 2018 Equity Incentive Plan (the "2018 Plan"), each non-employee director may elect to convert his or her annual cash compensation under the outside director compensation policy into an award of restricted stock units ("RSUs") under our 2018 Plan. If the non-employee director makes this election in a timely manner in accordance with the outside director compensation policy, each such award of RSUs automatically will be granted on the first trading day after January 1 of the calendar year for which the election applies and have a value (as defined in our outside director compensation policy) equal to the aggregate amount of such annual cash compensation, rounded down to the nearest whole share. Each such award of RSUs will vest as to 100% of the award on the last day of the calendar year in which the date of grant of the award occurs, subject to the non-employee director's continued service with us through the applicable vesting date.

*Initial Award.* Subject to the limits in the 2018 Plan, each person who first becomes a non-employee director automatically is granted an initial award of RSUs, which we refer to as the initial award, covering a number of shares of our common stock having a value (determined in accordance with the outside director compensation policy) equal to $120,000 (or a lesser amount determined by our board of directors in its sole discretion before the grant date), which grant will be effective on the first trading date on or following the date on which such person first becomes a non-employee director, whether through election by our stockholders or appointment by the board of directors to fill a vacancy; provided, however, that the number of shares covered by an initial award will be rounded down to the nearest whole share. Each initial award is scheduled to vest one-third on each of the first three anniversaries of the date the initial award is granted, in each case, subject to the non-employee director continuing to be a service provider through the applicable vesting date.

For any new non-employee director elected at an annual meeting, his or her initial award will be granted in lieu of, and not in addition to, the annual award that otherwise would have been granted to the non-employee director for that annual meeting.

*Annual Award.* Subject to the limits in the 2018 Plan, each non-employee director automatically receives, on the date of each annual meeting of our stockholders, an annual award of RSUs, each of which we refer to as an annual award, covering a number of shares of our common stock having a value (determined in accordance with the outside director compensation policy) of $80,000, rounded down to the nearest whole share under our outside director compensation policy; provided that, for any annual award scheduled to be granted on the date of an annual meeting, any non-employee director who is not continuing as a director following the applicable annual meeting will not receive an annual award with respect to such annual meeting. Each annual award will vest on the earlier of (i) the one-year anniversary of the date the annual award is granted or (ii) the day prior to the date of the next annual meeting following the date the annual award is granted, in each case, subject to the non-employee director continuing to be a service provider through the applicable vesting date.

Under our outside director compensation policy, no non-employee directors may be paid, issued or granted, in any fiscal year, cash compensation with an aggregate value greater than $150,000 and equity compensation with an aggregate value greater than $300,000 (with the value of each award determined in accordance with the outside director compensation policy). Any cash compensation paid or equity awards granted to an individual for his or her services as an employee, or for his or her services as a consultant (other than as a non-employee director), will not count against this limitation.

We have a practice of reimbursing directors for travel, lodging and other reasonable expenses incurred in connection with their attendance at board or committee meetings. We encourage directors to participate in continuing education pertinent to their service on our board, and we reimburse directors for such expenses up to an annual limit of $2,000.

On April 1, 2026, pursuant to the compensation committee's recommendation, our board of directors approved an amendment and restatement of our outside director compensation policy that increased the compensation of non-employee directors, effective on April 1, 2026, as follows:

The following additional changes were made to the policy:

*Initial Award.* For any new non-employee director elected at an annual meeting, his or her initial award will be in addition to the annual award granted to the non-employee director for that annual meeting.

Annual limit for outside director compensation was increased to allow for the changes noted above. Under our outside director compensation policy, no non-employee directors may be paid, issued or granted, in any fiscal year, cash compensation and equity compensation (with the value of each award determined in accordance with the outside director compensation policy) with an aggregate value greater than $1,500,000 for a non-employee director's first year of service or $1,000,000 in any subsequent year.

*Director Equity Ownership Guidelines*. We maintain equity ownership guidelines applicable to our non-employee directors who receive compensation pursuant to our outside director compensation policy. The guidelines allow for a compliance period, which in each case is the fifth anniversary of the later of the effective date of the guidelines or the date the applicable director becomes a director. The guidelines require non-employee directors to hold equity interests in our company with an aggregate value equal to three times the annual cash retainer for board service by the end of their respective compliance periods. For purposes of satisfying the equity ownership guidelines, equity interests only include issued shares of our common stock: (1) directly owned by a director or his or her immediate family members residing in the same household; (2) beneficially owned by director, but held in trust, limited partnerships, or similar entities for the sole benefit of the director officer or his or her immediate family members residing in the same household; and (3) held in retirement or deferred compensation accounts for the benefit of a director or his or her immediate family members residing in the same household.

The compensation committee may waive these requirements for non-employee directors joining our board of directors from government, academia or similar professions, and may temporarily suspend these requirements for a director if compliance would create severe hardship or prevent the director from complying

with a court order. As of December 31, 2025, all of our non-employee directors satisfy the equity ownership guidelines for non-employee directors or have time remaining in their compliance period to meet the guidelines.

**Director Compensation for Fiscal Year 2025** 

The following table sets forth information concerning the compensation paid or accrued for services rendered to us by members of the board of directors for the year ended December 31, 2025.

**PROPOSAL NO. 1 ELECTION OF DIRECTOR**<br>

Our board of directors is currently comprised of nine members. In accordance with our certificate of incorporation, our board of directors is divided into three staggered classes of directors.

Bandel Carano and Raymond Link are not standing for reelection at the Annual Meeting. Messrs. Carano and Link have been valuable members of our board of directors for many years. At the Annual Meeting, one Class II director will be elected for a three-year term to succeed the same class whose term is then expiring. Effective as of the end of Messrs. Carano and Link's current terms as directors at the Annual Meeting, the size of our board of directors will be seven directors.

Each director's term continues until the election and qualification of his or her successor, or such director's earlier death, resignation, or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of our company.

**Nominee**

Our nominating and corporate governance committee has recommended, and our board of directors has approved, Geoffrey Moore as nominee for election as a Class II director at the Annual Meeting. If elected, Dr. Moore will serve as a Class II director until our 2029 annual meeting of stockholders and until his successor is duly elected and qualified. Dr. Moore is currently a director of our company. For information concerning Dr. Moore, please see the section titled "Board of Directors and Corporate Governance."

If you are a stockholder of record and you sign your proxy card or vote by telephone or over the Internet but do not give instructions with respect to the voting of directors, your shares will be voted "FOR" the election of Dr. Moore. We expect that the director nominee will accept such nomination; however, in the event that he is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee designated by our board of directors to fill such vacancy. If you are a street name stockholder and you do not give voting instructions to your broker or nominee, your broker will leave your shares unvoted on this matter.

**Vote Required**

The election of directors requires a plurality vote of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon to be approved. Broker non-votes will have no effect on this proposal.

**THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE NOMINEE NAMED ABOVE.**

**PROPOSAL NO. 2 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**<br>

Our audit committee has appointed KPMG, independent registered public accountants, to audit our consolidated financial statements for our fiscal year ending December 31, 2026. During our fiscal year ended December 31, 2025, KPMG served as our independent registered public accounting firm.

Notwithstanding the appointment of KPMG and even if our stockholders ratify the appointment, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our audit committee believes that such a change would be in the best interests of our company and our stockholders. At the Annual Meeting, our stockholders are being asked to ratify the appointment of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2026. Our audit committee is submitting the appointment of KPMG to our stockholders because we value our stockholders' views on our independent registered public accounting firm and as a matter of good corporate governance. Representatives of KPMG will attend the Annual Meeting, and they will have an opportunity to make a statement and will be available to respond to appropriate questions from our stockholders.

If our stockholders do not ratify the appointment of KPMG, our audit committee may reconsider the appointment.

**Fees Paid to the Independent Registered Public Accounting Firm** 

The following table presents fees for professional audit services and other services rendered to our company by KPMG for the fiscal years ended December 31, 2025 and 2024 (in thousands):

<u>&nbsp;&nbsp;&nbsp;&nbsp;</u>

<sup>(1)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Audit fees consist of fees billed for professional services provided in connection with the audits of our annual consolidated financial statements and the effectiveness of our internal control over financial reporting, and the review of our quarterly consolidated financial statements included in our quarterly reports for fiscal years 2025 and 2024. Audit fees also include services that are normally provided by the independent registered public accounting firm in connection with statutory audits of our foreign subsidiaries in China and Finland.

<sup>(2)</sup> &nbsp;&nbsp;&nbsp;&nbsp;All other fees include any fees billed that are not audit or audit-related. In 2025 and 2024, these fees related to accounting research software.

(3)&nbsp;&nbsp;&nbsp;&nbsp;The audit fees for 2024 have been revised from the fees previously disclosed in the proxy statement for our 2025 Annual Meeting of Stockholders to include fees associated with statutory audits of our subsidiaries in China and Finland.

**Auditor Independence**

Pursuant to its charter and the policy described further below, our audit committee pre-approves audit and non-audit services rendered by our independent registered public accounting firm, KPMG. Our audit committee has determined that the rendering of non-audit services for tax compliance is compatible with maintaining the independence of KPMG.

**Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm**

The charter of the audit committee provides for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, KPMG. The chairperson of the audit committee, or a member of the audit committee delegated by the chairperson of the audit committee, may pre-approve all audit and permissible non-audit and tax services that may be provided by our independent registered public accounting firm, as long as this pre-approval is reported to the full audit committee at its scheduled meetings.

**Vote Required**

The ratification of the appointment of KPMG as our independent registered public accounting firm requires the affirmative vote of a majority of the voting power of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote "AGAINST" this proposal and broker non-votes will have no effect on this proposal.

**REPORT OF THE AUDIT COMMITTEE**

The audit committee is responsible for overseeing our accounting and financial reporting processes and internal control systems, the adequacy of the system of internal control over financial reporting, the appointment, compensation, retention and oversight of KPMG, our independent registered public accounting firm, and audits of our financial statements and the effectiveness of our internal control over financial reporting, all pursuant to the audit committee's written charter. KPMG reports directly to the audit committee. The audit committee has the authority to obtain advice and assistance from outside legal, accounting or other advisors as the audit committee deems necessary to carry out its duties.

With respect to the company's financial reporting process, the management of the company is responsible for (1) establishing and maintaining internal controls over preparation of the company's financial statements and (2) preparing the company's consolidated financial statements. KPMG is responsible for auditing these financial statements and the effectiveness of internal controls over financial reporting. It is the responsibility of the audit committee to oversee these activities. It is not the responsibility of the audit committee to prepare the company's financial statements. These are the fundamental responsibilities of management. In the performance of its oversight function, the audit committee has:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reviewed and discussed the audited financial statements with management, including a discussion of the company's internal control over financial reporting

**PROPOSAL NO. 3 ADVISORY VOTE ON COMPENSATION OF NAMED EXECUTIVE OFFICERS**<br>

At our 2021 annual meeting of stockholders, our board of directors recommended and our stockholders approved holding a non-binding advisory vote on the compensation of our named executive officers every year. Accordingly, pursuant to Section 14A of the Exchange Act and in accordance with SEC rules, we are providing our stockholders with the opportunity to cast a non-binding advisory vote to approve the compensation of our named executive officers as described in this proxy statement. This proposal gives our stockholders the opportunity to express their views on the design and effectiveness of our executive compensation program.

**Advisory Non-Binding Vote on Compensation of Named Executive Officers**

We believe that our compensation philosophy and program, as described below in the "Compensation Discussion and Analysis" section of this proxy statement, are effective in achieving our goals, and that the executive compensation reported in this proxy statement is appropriate, competitive, and aligned with our results. The compensation program for our named executive officers embodies a pay-for-performance philosophy. The program is designed to attract, motivate, and retain executive officers in a competitive market for executive talent, and to align the executive officers' interests with the interests of our stockholders to create long-term value, while at the same time avoiding the encouragement of excessive risk-taking. Our executive officers can achieve higher overall compensation if and to the extent we achieve challenging financial and strategic performance goals and our stock outperforms the market.

For a more detailed discussion of our compensation philosophy, objectives, principles, and programs, we strongly encourage our stockholders to review this proxy statement, and in particular the information contained in "Executive Compensation—Compensation Discussion and Analysis" and in the compensation tables and narrative that follow it in the "Executive Compensation" section of this proxy statement.

The vote on executive compensation is not intended to address any specific element of compensation or any specific named executive officer, but rather the overall compensation of all of our named executive officers and the philosophy, policies and practices described in this proxy statement.

Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to our named executive officers and will not be binding on us, our compensation committee, or our board of directors. Although the vote is non-binding, our compensation committee and our board of directors value the opinions expressed by our stockholders in their vote and will consider the outcome of the vote in making future compensation decisions for our named executive officers. After the vote held at the Annual Meeting, our next non-binding advisory vote on the compensation of our named executive officers is scheduled to be held at our 2026 annual meeting of stockholders.

At the Annual Meeting, we are asking stockholders to vote on the following non-binding advisory resolution:

**RESOLVED,** that the stockholders approve the compensation of nLIGHT's named executive officers as disclosed pursuant to the compensation disclosure rules of the SEC, in this proxy statement, including in the "Executive Compensation—Compensation Discussion and Analysis" section and in the compensation tables and narrative that follow it in the "Executive Compensation" section.

**Vote Required**

Approval of the compensation of our named executive officers requires the affirmative vote of a majority of the voting power of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote "AGAINST" this proposal and broker non-votes will have no effect on this proposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total revenue of $261.3 million increased 31.6% compared to 2024 as a record year from our Aerospace and Defense markets drove positive results.

–Record revenue of $175.3 million from our Aerospace and Defense markets grew 60% year-over-year on the successful execution against a number of existing programs, increased fiber amplifier shipments, and new awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin increased to 29.8% in 2025, compared to 16.6% in 2024 on higher volumes, more favorable customer and product mix, and better cost absorption.

–2025 products gross margin of 37.8% increased from 21.0% in 2024.

<sup>(1)&nbsp;&nbsp;&nbsp;&nbsp;</sup>A reconciliation of GAAP net loss to adjusted EBITDA (non-GAAP) for 2024 and 2025 is provided in Appendix A.

***Executive Compensation Philosophy***

Our executive compensation program is designed to achieve the following three primary objectives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Attract, retain and motivate highly skilled individuals based upon their contribution to the success of our company, and that of our stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Drive outstanding achievement of business objectives and reinforce our strong pay-for-performance culture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Align our named executive officers' interests with the long-term interests of our stockholders, with a focus on performance that drives value creation for our stockholders.

Our executive compensation program emphasizes long-term equity compensation as the most significant component of each named executive officer's compensation, aligning the compensation of our named executive officers with stockholder returns. The only fixed component of our named executive officers' annual compensation is base salary.

The compensation committee of our board of directors oversees our executive compensation program and seeks to provide compensation opportunities for our executive officers in a manner consistent with our business strategy, competitive market practice, sound corporate governance principles and stockholder interests. The core principle of our executive compensation philosophy is to pay-for-performance.

Our compensation philosophy continues to focus on pay-for-performance. We closely aligned the compensation paid to our named executive officers with achievement of both near-term financial objectives and long-term stockholder value. In 2025, we structured our compensation mix such that approximately 91% of the target total direct compensation awarded to our chief executive officer was in the form of equity awards and variable cash incentives and only 9% in the form of base salary. The allocation of shares in our equity awards was one-half time-based and one-half performance-based to reward long-term performance consistent with retention incentives. The graphic below shows the target total direct compensation mix for 2025 for our chief executive officer. The target total direct compensation mix for 2025 reflects actual salary, target cash incentive awards, and the grant date fair value of the annual grant of time-vested and

performance-based equity awards, with the performance-based equity valued based on Total Shareholder Return.

In August 2025, the compensation committee of our board of directors approved a special performance-based equity grant to incentivize achievement of certain stock price thresholds. This special grant is not reflected in the graphic below.

**Compensation Governance Practices**

***What We Do***

---

| | |
|:---|:---|
| ***Independent Compensation Committee and Compensation Consultant.*** The compensation committee is comprised solely of independent directors. The compensation committee solicits advice from independent compensation consultants retained directly by the compensation committee.<br>***Risk Analysis.*** Compensation programs are structured to avoid inappropriate risk taking by our executives and all employees by having the appropriate pay philosophy to support reasonable business objectives.<br>***Incentive Award Opportunities Capped.*** We limit our performance-based cash incentive awards to 160% of the target, and we limit our performance-based equity incentive awards to 200% of the target. The special PRSU grant in August 2025 does not have a multiplier.<br>***Pay-for-Performance.*** Named executive officer compensation is heavily weighted toward at-risk performance-based compensation, with cash incentives based upon achievement of financial targets and performance-based equity being earned based upon achievement of relative Total Shareholder Return. | ***Double-Trigger Change in Control Provisions.*** All equity awards granted to named executive officers since our initial public offering in 2018 are subject to "double-trigger" provisions under our change in control agreements, and the level of severance thereunder is reasonable and comparable to market-competitive levels.<br>***Annual Executive Compensation Review.*** The compensation committee conducts an annual review of our executive compensation program, including a review and determination of our compensation peer group used for comparative purposes and other factors.<br>***Strict Equity Ownership Guidelines.*** We have adopted strict equity ownership guidelines for our executive officers and directors.<br>***Clawback Policy.*** The compensation committee has adopted a compensation recovery policy that is intended to comply with the requirements of the Exchange Act and NASDAQ listing standard. Our policy allows us to recover certain incentive-based compensation payable to an executive officer if we are required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement under applicable securities laws.  |

***What We Don't Do***

---

| | |
|:---|:---|
| ***No Special Perquisites.*** We did not provide, nor do we have any plans to provide, any special benefits or perquisites to our named executive officers in 2025.<br>***No Hedging or Pledging.*** Our insider trading policy strictly prohibits our directors and executive officers from purchasing options on our securities, pledging our stock in a margin account or otherwise entering into transactions designed to hedge or offset any decrease in the market value of our stock.<br>***No Guarantees of Employment.*** We do not have any employment contracts with any of our executive officers that guarantee a term of employment, contain extraordinary severance provisions or guarantee salary increases or bonus amounts. | ***No Special Retirement or Health and Welfare Benefit Plans.*** We do not offer, nor do we have plans to offer, supplemental pension arrangements, defined benefit retirement plans, nonqualified deferred compensation plans, or any special health and welfare benefits programs to our executive officers that are different from or in addition to what is offered to our other employees.<br>***No Dividends or Dividend Equivalents Payable on Unvested Equity Awards.*** We do not pay, nor do we have any plans to pay, dividends or dividend equivalents on unvested or unearned equity compensation awards. |

**Compensation-Setting Process**

The compensation committee is responsible for determining our executive compensation philosophy, objectives, policies and programs and retains authority to determine all matters of compensation and benefits for our named executive officers. With respect to our named executive officers, the compensation committee

------

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

reviews and approves their annual base salaries, cash incentive opportunities and payments, long-term equity compensation opportunities and payments and other compensation, if any.

Our chief executive officer provides input with respect to adjustments to annual base salaries, annual cash incentive opportunities, long-term equity incentive compensation opportunities, program structures and other compensation-related matters for our named executive officers. The compensation committee reviews and discusses these recommendations and proposals with our chief executive officer and uses them as one factor in determining and approving the compensation for our named executive officers. Our chief executive officer does not determine his own compensation.

The compensation committee has the authority to select and retain an independent compensation consultant to provide advice and recommendations on competitive market practices and input on specific compensation decisions, and in 2025 the compensation committee engaged Compensia.

***Peer Group***

The compensation committee periodically examines the compensation practices of a defined peer group of companies, supplemented by survey data using similar peer group parameters, to assess the competitiveness of the elements of our executive officer compensation programs. The compensation committee completed its annual review of our peer group, taking into consideration changes in our market capitalization and the perspectives of outside investors and governance advisory groups. Based on this review in 2025, the only change to our peer group was removal of Axcelis Technologies. In reviewing the specific companies, the compensation committee considered objective criteria, such as industry, market capitalization, revenues and headcount, as well as stage of the company and if the company considered us a peer. The revised peer group consisted of 12 companies for the purposes of evaluating the competitiveness of our executive officer and non-employee director compensation in 2025. Our peer group includes companies in related industries with market capitalization ranging from approximately 0.3x to 6.6x our market capitalization and revenues ranging between approximately 0.4x and 4.3x our annual revenues, as of the date of the analysis in 2025.

---

The compensation committee used the competitive market data to inform its judgment about 2025 executive compensation decisions but did not benchmark or target compensation of any executive officer to a specific percentile. In 2025, the compensation committee used the competitive market data to inform discussions about non-employee director compensation and changes effective in 2026.

**Elements of Executive Compensation**

Our executive compensation program emphasizes the following three primary components:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• base salary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performance-based cash incentives that will only be paid based on achievement of key financial targets approved by the compensation committee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• long-term equity incentives that are issued in the form of both performance-based RSUs, for encouraging performance based on goals aligned with delivering value for our stockholders, and time-vested RSUs, for retention and reinforcing our ownership culture and alignment with stockholders.

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

In addition, each of our executive officers participates in a variety of benefit plans that are generally available to all U.S. employees, and has an employment agreement providing for severance benefits in connection with a qualifying termination.

The compensation committee takes a holistic view on our executive compensation program, seeking to ensure the overall program is meeting the company's objectives while providing the compensation committee with the flexibility to structure individual compensation packages that are market-competitive.

We focus on total target direct compensation, and factor in all aspects of pay, including base salary, performance-based cash incentives and time- and performance-based long-term equity incentives, to maintain an executive compensation program that is competitive. The compensation committee does not have a specific formula that is used between the elements of pay but applies its business judgment in providing compensation opportunities for our executives that promote the interests of our stockholders over both the near-term and long-term. To inform its judgment, the compensation committee examines peer group compensation practices, and with an understanding of those practices, seeks to create an appropriately leveraged, variable compensation program for our named executive officers that reinforces our pay-for-performance culture.

***Base Salaries***

Base salaries are designed to provide a level of fixed compensation.

The compensation committee reviews base salaries for our executive officers on an annual basis. Adjustments are determined by the compensation committee based on a number of factors, including the level of responsibility, expertise, and experience of the individual, internal equity, individual and company performance, competitive conditions in the industry, and base salaries for individuals in comparable positions at comparable companies, while taking into account the company's cash flow considerations. The compensation committee also considers recommendations made by our chief executive officer regarding salary rate adjustments for his direct reports.

The compensation committee approved an increase in the base salary of Mr. Keeney from $460,000 to $483,000 and an increase in the base salary of Mr. Corso from $315,000 to $330,750 effective April 2025.

***Performance-Based Cash Incentive Opportunities***

Each named executive officer was assigned a target cash incentive opportunity, the amount of which was calculated as a percentage of their 2025 annual base salary paid for the year. The following table shows the target incentive of each named executive officer for 2025 compared to 2024:

---

| | | |
|:---|:---|:---|
| **Named Executive Officer** | **2025 Target Cash Incentive as a % of Base Salary** | **2024 Target Cash Incentive as a % of Base Salary** |
| Scott Keeney | 100% | 100% |
| Joseph Corso | 65% | 65% |

---

***Cash Incentive Structure and Objectives***

The 2025 annual cash incentive awards for our named executive officers were determined based on the achievement of revenue and profitability targets set at the beginning of the year based on our annual operating plan, as set forth below. Overall achievement is weighted 50% on revenue and 50% on adjusted EBITDA, with a maximum aggregate cash incentive payout of 160% of the target opportunity. For revenue, a minimum threshold of 90% achievement is required for a 90% payout, and the maximum payout is 120% for 120% achievement of the revenue target. For adjusted EBITDA, a minimum threshold of 25% achievement must be met before any cash incentive payout is earned with a maximum payout of 200%. We believe that the measures of revenue and adjusted EBITDA used for cash incentive awards are well aligned with how investors assess our operating performance and therefore represents an appropriate basis in implementing our pay-for-performance approach.

The following is an illustration of the calculation of individual cash incentive payments for our named executive officers.

|:---|:---|:---|:---|:---|
| **2025 Financial Targets** | **Target** | **Actual** | **Weight** | **Achievement** |

| Adjusted EBITDA (in millions) <sup>(1)</sup> | $0.0 | $31.2 | 50% | 200% |
| Total |  |  | 100% | 159% |

---

<sup>(1)&nbsp;&nbsp;&nbsp;&nbsp;</sup>The target and actual adjusted EBITDA used in the calculation of cash incentive compensation achievement excludes incentive compensation and the effect of any non-ordinary course events determined by the compensation committee to be not within the annual operating plan used to set applicable performance targets under the cash incentive compensation plan.

In accordance with our 2025 incentive compensation plan, we paid incentive compensation to our named executive officers in March 2026 equal to approximately 159% of their target incentive opportunity. The 2025 non-equity (cash) incentive compensation earned but not paid as of December 31, 2025 is reflected in the Summary Compensation Table below.

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

***Long-Term Equity Incentives***

Our 2018 Plan authorizes us to grant different types of equity awards, including stock options, time-based restricted stock awards ("RSAs") or RSUs and performance-based RSAs or RSUs. Equity awards to our named executive officers are determined by the compensation committee in accordance with the 2018 Plan and our administrative guidelines. Equity compensation is used to reward performance and contributions to our company, as well as to promote retention.

The compensation committee believes that equity compensation is a key component of our pay-for-performance compensation philosophy and is an effective way to align compensation for named executive officers over a multi-year period directly with the interests of our stockholders by motivating and rewarding creation and preservation of stockholder value. Equity awards to our named executive officers are generally made on an annual basis, along with the annual equity awards made to other employees of our company. All annual grants are approved by the compensation committee under our guidelines for equity awards and typically are scheduled to vest during what we anticipate will be an open trading window under our insider trading policy. The compensation committee also considers and grants equity awards for special situations, such as promotions, from time to time.

***2025 Annual Equity Awards***

In 2025, the compensation committee issued annual equity awards in the form of a combination of time-vested and performance-based RSUs to our named executive officers.

Time-vested RSUs were granted for their retentive effect and because their value is directly impacted by all stock price changes and therefore tied directly to stockholder value. Performance-based RSUs ("PRSUs") were also granted to our named executive officers in 2025. The vesting of these PRSUs is subject to our achievement of a three-year Total Shareholder Return goal ("TSR") based on our TSR relative to the Russell 2000 index. As a result, the value of these PRSUs is directly impacted by our stock performance relative to peers and tied to stockholder value, reflecting our continued commitment to a pay-for-performance philosophy.

The size of the annual equity grants made to our named executive officers is determined in light of the compensation committee's objective of providing total target direct compensation that is competitive with market practices but also taking into account recent stock price performance.

However, 2025 was a year of transitions for us, and it was no different for our long-term equity incentive programs. Our compensation committee noted the transitions in our business plan and retention needs and determined that an additional pay for performance program would be appropriate. Therefore, it undertook a vigorous special-cycle analysis of our equity compensation programs and following that analysis, in August 2025, approved a special one-time grant of performance-based RSUs ("Special PRSUs") in addition to the annual time-based and performance-based RSUs. The number of units earned is based on achievement of ambitious and rigorous stock price goals that must be achieved during a 6-year period, beginning on August 13, 2025. The compensation committee believes that the Special PRSUs demonstrate and reinforce our commitment to a philosophy of pay-for-performance by only vesting in the event that we are able to achieve significant increases in stockholder value and that such increases are sustained over a 60-day period. Our compensation committee believes that the Special PRSUs present a clear pay-for-performance linkage by only rewarding executives in the event that stockholders recognize significant gains. Although our compensation program has historically been heavily weighted toward long-term performance-based equity compensation, the Special PRSU program increased that weighting significantly in 2025. However, the Special PRSUs were designed with a dual-performance and incentive structure, with the intention of incentivizing long-term retention of our executive team, with 50% of earned Special PRSUs remaining unvested and subject to continued service requirements until January 3, 2028, and 50% until January 3, 2029, subject to certain protections in the case of qualified terminations. This provides us with three years of

retention value with respect to our executives, and we believe that, in the fast-paced and every changing market in which we operate, this retention value will provide long-term benefits to our stockholders.

The individual amounts for the 2025 annual and special equity awards granted to our named executive officers are set forth in the table below:

<sup>(1)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Annual performance-based RSUs reflect the "target" number of shares that can be earned based on performance. Actual shares earned may vary from 0% to 200% of the "target" number.

<sup>(2)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Special performance-based RSUs reflect the maximum number of shares that can be earned based on performance.

The time-based RSUs granted to our named executive officers vest over a period of three years from the effective date, with one-third vested on March 1, 2026 and one-twelfth vesting each quarter thereafter for the next eight calendar quarters subject to the executive officer's continued service with us, and further subject to vesting acceleration as described in the "Potential Payments upon Termination or Change-In-Control" section below.

The PRSUs granted to our named executive officers in 2025 will vest following the end of a three-year performance period, subject to the executive officer's continued service to us, with the number of units eligible for vesting determined based on performance of our TSR for the period from May 9, 2025 through March 31, 2028 (the period is subject to adjustment in the event we experience a change in control as described below) relative to the TSRs for the same time period of the companies identified as being part of the Russell 2000 Index as of May 9, 2025, that remain listed on any established stock exchange or national market system as of March 31, 2028. The PRSUs that become eligible for vesting based on our relative TSR performance will be between 0% and 200% of the target amount, with a maximum vesting of 100% if our TSR is negative, as measured by a third-party valuation firm and approved by the compensation committee.

The table below reflects selected details relating to the PRSUs granted to our named executive officers in 2025.

_________________

<sup>(1) &nbsp;&nbsp;&nbsp;&nbsp;</sup>The percentage of PRSUs eligible for vesting is capped at 100% if our TSR over the performance period is negative.

<sup>(2)</sup> &nbsp;&nbsp;&nbsp;&nbsp;If our TSR over the performance period is between the 25th and 50th percentile, or it is positive and between the 50th and 75th percentile, then the percentage of the target number of PRSUs that will be eligible to vest will be interpolated linearly between the corresponding percentages designated for those percentiles.

In the event that we experience a change in control as defined in the 2018 Plan before March 31, 2028, then performance on the relative TSR goal for these PRSUs will be measured over a reduced period from May 9, 2025 to the third trading day prior to the date of the change in control, and our TSR for this period will be measured using the per share price payable in the change in control as the ending stock price.

the possibility of double-trigger vesting upon a qualifying termination if provided under another agreement, such as an employment agreement.

The Special PRSUs granted to our named executive officers on August 13, 2025 will be earned subject to the achievement of specified stock price goals, measured on a volume-weighted average stock price over a trailing consecutive 60-day period ("Stock Price Goals") during the 6-year period beginning on August 13, 2025 and continued service through the applicable date of certification of achievement. The Stock Price Goals are (i) $30, (ii) $35, and (iii) $40, for each one-third tranche of Special PRSUs, respectively. The $30 Stock Price Goal was achieved in December 2025, and both the $35 and $40 Stock Price Goals were achieved in January 2026, and this achievement was certified by the Compensation Committee, such that all of the Special PRSUs granted are now earned ("Earned Units"). Approximately 50% of the Earned Units will vest January 3, 2028, and 50% of the Earned Units will vest January 3, 2029, in each case subject to continued service through the applicable vesting date. If the Company's volume-weighted stock price did not exceed the Stock Price Goals, then no Special PRSUs would become Earned Units or become eligible to vest.

In the event that we experience a change in control, and the successor or acquiring entity does not assume or substitute for the Earned Units, the Earned Units will vest in connection with the change in control; otherwise, the Earned Units will remain subject to the applicable service-based requirements. The form of Special PRSU Agreement provides that Special PRSUs are subject to accelerated vesting upon certain qualifying terminations of employment and continued vesting eligibility upon certain qualifying terminations of service, subject to the effectiveness of a release of claims, as described in the Special PRSU Agreement and, with respect to Mr. Keeney, his Amended Employment Agreement.

See the table entitled "Grants of Plan-Based Awards in Fiscal Year 2025" in this section of the proxy statement for additional information regarding these equity awards to our named executive officers in 2025.

**Change of Control and Severance Benefits; Transition Arrangements**

Our change of control severance agreements with our named executive officers and certain of our other officers are described in this Proxy Statement under "Employment Arrangements."

The compensation committee believes that these agreements protect the interests of our stockholders by providing a framework for avoiding the distraction and loss of key management personnel that may occur in connection with rumored or actual fundamental corporate changes. The uncertainty about the future status of employment among management that can arise in the face of a potential change of control could result in the untimely departure or distraction of key officers. Change of control severance agreements provide support to officers to remain with our company despite uncertainties while a change of control is under consideration or pending and the compensation committee believes that the potential benefits under these agreements are reasonable and generally comparable to competitive agreements offered by our peer companies to their senior executives. Severance benefits are "double-trigger," which means that they are provided to the executive only in the event that the executive is terminated, or the executive involuntarily experiences material changes in terms of employment, as defined in each agreement, following a change of control. We do not provide for gross ups for excise taxes under Section 280G of the Internal Revenue Code of 1986, as amended (the "Code").

Under our 2018 Plan, if a change in control occurs, any outstanding equity awards that are not assumed or substituted for in the transaction will become fully vested and exercisable, and all such performance-based equity awards will be deemed earned at the greater of target or actual results immediately prior to the change in control.

**Other Benefits and Perquisites**

Our named executive officers participate in various employee benefit plans, including health, dental and vision care plans, life insurance and our 401(k) plan and stock purchase plans. These benefit plans are the same plans offered to our other employees.

**Consideration of Stockholder Advisory Vote on Executive Compensation**

At our 2025 Annual Meeting of Stockholders, approximately 93% of the votes on our non-binding, advisory proposal to approve compensation provided to our named executive officers in 2024 voted "FOR" the approval of the proposal. Although this advisory vote is not binding on our compensation committee, the compensation committee considers this result in its review and approval of our executive compensation programs and policies.

**Equity Ownership Guidelines**

We have equity ownership guidelines for our executive officers as well as our non-employee directors. For more information about our equity ownership guidelines for non-employee directors, see "Board of Directors and Corporate Governance—Outside Director Compensation—Director Equity Ownership Guidelines." The guidelines require our chief executive officer to hold shares equal in value to three times annual base salary. Other executive officers must hold shares equal in value to their annual salary. Executive officers have five years from November 1, 2019, when the guidelines were adopted, or if later, from the time they become executive officers, to meet the ownership guidelines. Shares counted for this purpose include issued shares owned by the executive officer or members of the executive officer's immediate family members residing in the same household, including shares held in trusts, limited partnerships, or similar entities for the sole benefit of the executive officer or his immediate family members residing in the same household.

As of December 31, 2025, all of our executive officers satisfy the equity ownership guidelines for executive officers.

**Compensation Recovery Policy**

Our compensation recovery policy is intended to comply with Section 10D and Rule 10D-1 of the Exchange Act and the relevant Nasdaq listing standards. Pursuant to the compensation recovery policy, if we are required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement under applicable securities laws, our compensation committee (or the independent members of our board of directors or another committee of independent members of our board of directors, if determined in the discretion of our board of directors) must determine what incentive-based compensation, if any, must be recovered from our executive officers. Subject to the limited exceptions set forth in the policy, the recovery of excess incentive-based compensation from current and former executive officers under the policy is non-discretionary, without regard to whether the executive officer was at fault for the accounting restatement. As described in more detail in the policy, excess compensation generally is incentive-based compensation that exceeds the amount an executive officer otherwise would have received had the compensation been determined based on the restated amounts. Excess compensation generally is covered by the policy if received by an executive officer on or after October 2, 2023 and during the three completed fiscal years immediately prior to the date it is determined that an accounting restatement is required, such amounts were received after the individual became an executive officer and such individual was an executive officer at any time during the applicable performance period for the incentive-based compensation.

**Policies and Practices Related to the Grant of Certain Equity Awards** 

We do not grant equity awards on a predetermined schedule, but typically approve equity awards at regularly scheduled meetings of our Compensation Committee during an open trading window. We have not granted, nor do we intend to grant, stock options in anticipation of the release of material, nonpublic information that is likely to result in changes to the price of our common stock, such as a significant positive or negative earnings announcement, and, we have not taken, nor do we intend to take, material nonpublic information into account when determining the timing or terms of stock options. Similarly, we have not timed, nor do we intend to time, the release of material, nonpublic information for the purpose of affecting the value of executive compensation or for any other purpose.

**Hedging and Pledging Prohibitions** 

We have an Insider Trading Policy, which, among other things, prohibits our employees, including officers, and our directors from making short sales, engaging in transactions in publicly-traded options (such as puts and calls) and other derivative securities relating to our common stock, pledging any of our securities as collateral for a loan and holding any of our securities in a margin account, whether such securities are granted as compensation or are held, directly or indirectly, by the employee or director. This prohibition extends to any hedging or similar transaction designed to decrease the risks associated with holding our securities.

**Deductibility of Executive Compensation** 

Section 162(m) of the Code generally limits the amount we may deduct from our federal income taxes for compensation paid to our chief executive officer and certain other executive officers to $1 million per executive officer per year, subject to certain exceptions. Neither our compensation committee nor its authorized committee has adopted a policy that all equity or other compensation must be deductible.

When approving the amount and form of compensation for our executive officers, we generally consider all elements of the cost to us of providing such compensation, including the potential impact of Section 162(m) of the Code, as well as our need to maintain flexibility in compensating executive officers in a manner designed to promote our goals. Our compensation committee or its authorized subcommittee, as applicable, may, in its judgment, authorize compensation payments that will or may not be deductible when it believes that such payments are appropriate to attract, retain or motivate executive talent.

**No Gross-Ups for Taxes on Parachute Payments and Deferred Compensation** 

We do not provide, and have no obligation to provide, any of our named executive officers with a "gross-up" or other reimbursement payment for any tax liability he or she might owe because of the application of Sections 280G, 4999 or 409A of the Code. If any of the payments or benefits provided for under the change of control and severance agreements or otherwise payable to a named executive officer would constitute "parachute payments" within the meaning of Section 280G of the Code and could be subject to the related excise tax, he or she would receive either full payment of such payments and benefits or such lesser amount that would cause no portion of the payments and benefits being subject to the excise tax, whichever results in the greater after-tax benefits to our named executive officer.

**Accounting for Stock-Based Compensation**

Our compensation committee considers accounting effects in designing compensation plans and arrangements for our executive officers and other employees. Chief among these is ASC 718, the standard which governs the accounting treatment of stock-based compensation awards. ASC 718 generally requires companies to measure the compensation expense for all share-based payment awards made to employees and directors, including stock options and restricted stock-based awards, based on the grant date "fair value" of these awards. This calculation is performed for accounting purposes and reported in the compensation

tables below, even though our executive officers may realize no value from their awards. ASC 718 also generally requires companies to recognize the compensation cost of their share-based payment awards in their income statements over the period that an executive officer is required to render service in exchange for the option or other award.

**Compensation Committee Report**

The compensation committee has reviewed and discussed the Compensation Discussion and Analysis provided above with management. Based on such review and discussions, the compensation committee has recommended to the board of directors that the Compensation Discussion and Analysis be included in our Annual Report on Form 10-K for the year ended December 31, 2025, and this proxy statement.

Respectfully submitted by the members of the compensation committee of the board of directors\*:

Bill Gossman (Chair)

Bandel Carano\*\*

Raymond Link\*\*

\*This compensation committee report is required by the SEC and, in accordance with the SEC's rules, will not be deemed to be a part of or incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act or the Exchange Act, except to the extent that we specifically incorporate this information by reference, and will not otherwise be deemed "soliciting material" or "filed" under either the Securities Act or the Exchange Act.

\*\* Messrs. Carano and Link are not standing for reelection and will cease to be members of our board of directors at the expiration of their terms at the Annual Meeting.

**Compensation Risk Analysis**

Our compensation committee reviews and discusses with management the risks arising from our executive compensation philosophy and practices applicable to all employees to determine whether they encourage excessive risk-taking and to evaluate compensation policies and practices that could mitigate such risks. Based on those reviews, the compensation committee structures our executive compensation program to align the executive officers' interests with the interests of our stockholders to create long-term value, while at the same time avoiding the encouragement of excessive risk-taking. We do believe that any potential risks arising from our compensation programs, policies and practices, including our executive compensation program, are not reasonably likely to have a material adverse effect on us.

<sup>(1)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Our named executive officers are eligible for a payout in the range of 0% to 160%.

<sup>&nbsp;&nbsp;&nbsp;&nbsp;</sup>

**CEO Pay Ratio Disclosure**

Under the Dodd-Frank Act and Item 402 of Regulation S-K under the Securities Act, we are required to disclose the ratio of the annual total compensation of our median-compensated employee to the annual total compensation of our CEO.

We selected December 31, 2025, the last day of our fiscal year 2025, as the date on which to determine our median employee. In order to identify our median-compensated employee, we aggregated compensation for all of our world-wide employees as of December 31, 2025, as follows: Annual base salary for regular salaried employees, or hourly rate multiplied by the expected annual work schedule for regular hourly employees, plus target annual bonus or commission. Components of compensation paid in foreign currency were converted to U.S. dollars based on currency exchange rates as of December 31, 2025 (other than our CEO). We then ranked this compensation measure for all of our worldwide employees and identified the median employee. Our median-compensated employee on a worldwide basis is an Engineering Technician in the United States. The compensation of our median employee does not include certain company-provided benefits such as health insurance, life insurance or employee stock purchase plan.

For 2025, the annual total compensation for Mr. Keeney, from the Summary Compensation Table above, was $37,333,189, and the annual total compensation for our median-compensated employee was $82,014, resulting in an estimated pay ratio of approximately 455:1.

As noted above, Mr. Keeney's cash compensation for 2025 was $1,247,189. The Summary Compensation Table total for Mr. Keeney for 2025 includes the following equity grants that are earned over time and subject to continued service:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the grant date fair value of time-based equity compensation awarded during 2025 that will be earned over three years;

------

<u>[Table of](#i191cf89563ef42329a4248f352f1efcd_16)[Contents](#i191cf89563ef42329a4248f352f1efcd_16)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the grant date fair value performance-based equity compensation awarded during 2025 that will be measured and earned in three years based on relative Total Shareholder Return, which is valued for purposes of the Summary Compensation Table and this pay ratio disclosure using a Monte Carlo simulation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the grant date fair value of performance-based equity compensation awarded during 2025 that will be earned in 2028 and 2029 based on achievement of specified Stock Price Goals, and is valued for purposes of the Summary Compensation Table and this pay ratio disclosure using a Monte Carlo simulation.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations, worldwide locations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

**Pay Versus Performance**

Under rules adopted pursuant to the Dodd-Frank Act (the "PvP Rules"), we are required to disclose certain information about the relationship between the compensation actually paid to our named executive officers and certain measures of company performance. The material that follows is provided in compliance with these rules; however additional information regarding our compensation philosophy, the structure of our performance-based compensation programs, and compensation decisions made this year is described above in our Compensation Discussion and Analysis.

The following table provides information regarding compensation actually paid to our principal executive officer ("PEO"), and other named executive officers ("Other NEOs") for each year from 2021 to 2025, compared to our TSR from December 31, 2020, through the end of each such year, and our net income and total revenue for each such year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For purposes of the above adjustments, the fair value of equity awards on the applicable date were determined in accordance with FASB's ASC Topic 718, using valuation methodologies that are generally consistent with those used to determine the grant-date fair value for accounting purposes.

_______________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.We have not reported any amounts in our Summary Compensation Table with respect to "Change in Pension and Nonqualified Deferred Compensation" and, accordingly, the adjustments with respect to such items prescribed by the PvP rules are not relevant to our analysis and no adjustments have been made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.The amounts reflect the aggregate grant-date fair value reported in the "Stock Awards" column in the Summary Compensation Table for the applicable year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.In accordance with PvP Rules, the fair values of unvested and outstanding equity awards to our PEO were remeasured as of the end of each fiscal year, and as of each vesting date, during the years displayed in the table above. The assumptions used for determining the fair values shown in this table do not differ materially from those used to determine the fair values disclosed as of the grant date of such awards. Please see "Accounting Assumption Disclosures" for further discussion on the assumptions used for these remeasurements.

(5)&nbsp;&nbsp;&nbsp;&nbsp;Peer Group TSR represents the cumulative return on a fixed investment of $100 in the S&P 600 Technology Hardware & Equipment (Industry Group) for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, assuming reinvestment of dividends.

(6) &nbsp;&nbsp;&nbsp;&nbsp;The dollar amounts reported are our net income as reflected in our audited financial statements.

**Relationship between CAP vs. Cumulative TSR of Company and the Peer Group**

We believe our pay-for-performance philosophy is well reflected in the table above because the "compensation actually paid" (as reported in the Pay versus Performance table above) tracks well to the performance measures disclosed in such tables.

**Most Important Performance Measures**

Following is an unranked list of the financial performance measures we consider most important in linking company performance and compensation actually paid to our NEOs for the most recently completed fiscal year. Further information on our performance measures is described in our Compensation Discussion & Analysis (CD&A) above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total Revenue

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Product Gross Margin

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Relative TSR

**Accounting Assumption Disclosures**

In accordance with the PvP Rules, the fair values of unvested and outstanding equity awards to our named executive officers were remeasured as of the end of each fiscal year, and as of each vesting date, during the years displayed in the Pay versus Performance table above. We approached the determination of fair value in the same way as we historically have determined fair value and fair values as of each measurement date were determined using valuation assumptions and methodologies that are generally consistent with those used to estimate fair value at grant under GAAP. Other than as disclosed below, all other valuation assumptions are materially consistent with the grant date assumptions. See Note 16 "Stockholders' Equity and Stock-Based Compensation" to the Consolidated Financial Statements of the Form 10-K for additional details on the valuation assumptions used at grant for the most-recently disclosed fiscal year.

**TSR Awards:** For PSUs with a TSR metric, the fair values as of each measurement date (prior to the end of the performance period) were determined using a Monte Carlo simulation pricing model, with assumptions and methodologies that are generally consistent with those used to estimate the fair value at grant under U.S. GAAP. The range of estimates used in the Monte Carlo calculations are as follows:

---

| | |
|:---|:---|
| **Assumption** | **2025** |
| Volatility | 61.15% - 75.63% |
| Dividend Yield | 0% |
| Risk-Free Rate | 3.42% - 3.74% |
| Correlation Coefficient | 0.4892 - 0.6739 |

---

**Performance Awards Without Market Conditions:** For performance-based awards with only performance conditions, the fair values reflect the probable outcome of the performance vesting conditions as of each measurement date.

**Outstanding Equity Awards at December 31, 2025** 

The following table presents information concerning equity awards held by our named executive officers as of December 31, 2025.

**Employment Arrangements**

Below is a summary of the employment arrangements for our named executive officers. Each of our named executive officers has executed our standard form of confidential information, invention assignment and arbitration agreement.

***Scott Keeney***

We entered into an employment agreement with Mr. Keeney in March 2018, which was amended and restated in August 2025. The employment agreement does not have a specific term and provides that Mr. Keeney is an at-will employee.

Pursuant to the employment agreement with Mr. Keeney, if we terminate the employment of Mr. Keeney other than for death, "disability," or "cause" (as such terms are defined in Mr. Keeney's employment agreement) outside of a change in control period (as defined below), and Mr. Keeney executes a waiver and release of claims in our favor that becomes effective and irrevocable within 60 days following his termination, Mr. Keeney will be entitled to (i) continuing payments of his base salary for a period of 12 months and (ii) premium payments to maintain group health insurance continuation benefits pursuant to "COBRA" for him and his respective dependents for up to 12 months, or taxable monthly payments of an equivalent amount for the same period. Mr. Keeney's then-outstanding equity awards will remain outstanding for three months or until the occurrence of a "change in control" (as defined in Mr. Keeney's employment agreement) (whichever is earlier) so that Mr. Keeney will be eligible to receive the vesting acceleration benefits described below to the extent applicable.

In addition, pursuant to the employment agreement with Mr. Keeney, if, within the period beginning three months prior to and ending 12 months following a "change in control" (as defined in Mr. Keeney's employment agreement) (such period referred to as the "change in control period"), the employment of Mr. Keeney is terminated other than for death, "disability," or "cause" or Mr. Keeney resigns for "good reason" and Mr. Keeney executes a waiver and release of claims in our favor that becomes effective and irrevocable within 60 days following his termination, Mr. Keeney will be entitled to (i) a lump sum payment equal to 18 months of his base salary, (ii) premium payments to maintain group health insurance continuation benefits pursuant to "COBRA" for him and his respective dependents for up to 18 months, or taxable monthly payments of an equivalent amount for the same period, and (iii) 100% of the then-unvested shares subject to his outstanding equity awards will immediately become vested and exercisable (in the case of equity awards with performance-based vesting, all performance goals and other vesting criteria will be deemed achieved at the greater of actual performance measured as of the date of termination or 100% of target levels, unless the amended and restated employment agreement or the applicable equity award agreement provides otherwise).

Mr. Keeney's employment agreement includes a Section 280G "best results" provision, which provides that if the severance payments or other benefits provided to the NEOs constitute "parachute payments" under Section 280G of the Internal Revenue Code, his severance and other benefits will be either (i) delivered in full or (ii) delivered only to a lesser extent that would result in no portion of such severance benefits being subject to applicable excise tax, whichever results in the greatest amount of after-tax benefits. We included this provision in the employment agreements to be clear that no Section 280G tax gross-ups would be provided.

***Joseph Corso***

We entered into an employment agreement with Mr. Corso in August 2020. The employment agreement does not have a specific term and provides that Mr. Corso is an at-will employee.

Pursuant to the employment agreement with Mr. Corso, if we terminate the employment of Mr. Corso other than for death, "disability," or "cause" (as such terms are defined in Mr. Corso's employment agreement) outside the change in control period (as defined below), and Mr. Corso executes a waiver and release of claims in our favor that becomes effective and irrevocable within 60 days following his termination, Mr. Corso will be entitled to (i) continuing payments of his base salary for a period of six months and (ii) premium payments to maintain group health insurance continuation benefits pursuant to "COBRA" for him and his respective dependents for up to six months, or taxable monthly payments of an equivalent amount for the same period. Mr. Corso's then-outstanding equity awards will remain outstanding for three months or until the occurrence of a "change in control" (as defined in Mr. Corso's employment agreement) (whichever is earlier) so that Mr. Corso will be eligible to receive the vesting acceleration benefits described below to the extent applicable.

In addition, pursuant to the employment agreement with Mr. Corso, if, within the period beginning three months prior to and ending 12 months following a "change in control" (as defined in Mr. Corso's employment agreement) (such period referred to as the "change in control period"), the employment of Mr. Corso is terminated other than for death, "disability," or "cause" or Mr. Corso resigns for "good reason" and Mr. Corso executes a waiver and release of claims in our favor that becomes effective and irrevocable within 60 days following his termination, Mr. Corso will be entitled to (i) a lump sum payment equal to 12 months of his base salary, (ii) premium payments to maintain group health insurance continuation benefits pursuant to "COBRA" for him and his respective dependents for up to 12 months, or taxable monthly payments of an equivalent amount for the same period, and (iii) 100% of the then-unvested shares subject to his outstanding equity awards will immediately become vested and exercisable (in the case of equity awards with performance-based vesting, all performance goals and other vesting criteria will be deemed achieved at the greater of actual performance measured as of the date of termination or 100% of target levels, unless the applicable equity award agreement provides otherwise).

Mr. Corso's employment agreement includes a Section 280G "best results" provision as described above for Mr. Keeney.

**Potential Payments upon Termination or Change-In-Control** 

The following tables provide information concerning the estimated payments and benefits that would be provided in the circumstances described above, assuming that the triggering event took place on December 31, 2025, the last day of our fiscal year. For purposes of valuing accelerated vesting, the values indicated in the tables below are calculated, with respect to RSAs or RSUs, as $37.51 (the closing price of a share of our common stock on December 29, 2025, the last trading day of 2025), multiplied by the number of unvested shares subject to the RSAs or RSUs as of December 31, 2025 that are being accelerated (and for performance-based RSAs or RSUs, based on the target number of shares). Neither Mr. Keeney nor Mr. Corso had any unvested stock options as of December 31, 2025.

**BENEFICIAL OWNERSHIP OF SHARES OF COMMON STOCK**

The following table sets forth certain information with respect to the beneficial ownership of our capital stock as of April 6, 2026 for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each beneficial owner of more than 5% of our common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each of our directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each of our named executive officers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all directors and executive officers as a group.

Applicable percentage ownership is based on 56,406,459 shares of our common stock outstanding as of April 6, 2026. The holders of common stock have the right to one vote per share.

Information with respect to beneficial ownership has been furnished by each director, officer or beneficial owner of more than 5% of our common stock. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules take into account shares of common stock issuable pursuant to the exercise of stock options that are either immediately exercisable or exercisable on or before the 60th day after April 6, 2026. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Except as otherwise noted below, the address for each person or entity listed in the table is c/o nLIGHT, Inc., 4637 NW 18th Avenue, Camas, Washington 98607.

**CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS**

There are no transactions since January 1, 2025, to which we have been a party in which the amount involved exceeded $120,000 and in which any of our executive officers, directors, promoters or beneficial holders of more than 5% of our capital stock had or will have a direct or indirect material interest, other than compensation arrangements which are described under the section of this proxy statement captioned "Executive Compensation."

**Policies and Procedures for Transactions with Related Persons**

We have a formal, written policy that our executive officers, directors (including director nominees), holders of more than 5% of any class of our voting securities and any member of the immediate family of or any entities affiliated with any of the foregoing persons, are not permitted to enter into a related party transaction with us without the approval or, in the case of pending or ongoing related party transactions, ratification of our audit committee. For purposes of our policy, a related party transaction is a transaction, arrangement or relationship where we were, are or will be involved and in which a related party had, has or will have a direct or indirect material interest.

The audit committee of our board of directors has the primary responsibility for reviewing and approving transactions with related parties. Our audit committee charter provides that the audit committee shall review and approve any related party transactions. In reviewing proposed related party transactions, the audit committee will only approve or ratify related party transactions that are in, or not inconsistent with, the best interests of us and our stockholders.

**Limitations on Director and Officer Liability and Indemnification**

Our certificate of incorporation and bylaws provide the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law (the "DGCL"). In addition, our certificate of incorporation provides that our directors shall not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director and that if the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

As permitted by the DGCL, we have entered into separate indemnification agreements with each of our directors and certain of our officers that require us, among other things, to indemnify them against certain liabilities which may arise by reason of their status as directors, officers or certain other employees. We maintain insurance policies under which our directors and officers are insured, within the limits and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities that might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being or having been directors or officers. The coverage provided by these policies may apply whether or not we would have the power to indemnify such person against such liability under the provisions of the DGCL.

We believe that these provisions and agreements are necessary to attract and retain qualified persons as our officers and directors. At present, there is no pending litigation or proceeding involving our directors or officers for whom indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.
