April 22, 2026

Dear Fellow Stockholders:

On behalf of the Board of Directors (the "Board") of Shimmick Corporation ("Shimmick"), I would like to express our appreciation for your interest in our company. It is my pleasure to invite you to Shimmick's Annual Meeting of Stockholders (the "Annual Meeting"), to be held virtually on Tuesday, June 2, 2026, at 11:00 a.m., Eastern Time.

As we reflect on 2025, the year represented an important period of transition for the Company. Management advanced the strategic priorities established at the outset of the year, and we are pleased that the Company finished the year operating generally in line with expectations while making tangible progress during a transformational period.

Shimmick implemented a strategy centered on three core priorities: growing the business through disciplined pursuit of work aligned with Shimmick's technical strengths; completing and exiting legacy, lower-margin non-core Projects; and improving operating consistency through stronger execution and cost control. Over the course of the year, management made meaningful progress across each of these areas. Shimmick further concentrated its activity on more strategic projects, continued to wind down non-core projects, and took steps to improve operational discipline. While these efforts are still underway, the Board believes the actions taken in 2025 have strengthened the underlying foundation of the business.

From a financial perspective, results reflected this increased focus. Project mix continued to shift toward work better aligned with Shimmick's core capabilities, contributing to improved margins in the core portfolio. At the same time, revenue associated with Non-Core Projects declined as planned, consistent with Shimmick's objective to exit those activities in an orderly manner. Liquidity remained solid throughout the year, providing Shimmick with appropriate flexibility to support ongoing operations. We remain focused on ensuring that management balances growth with risk, maintains appropriate controls, and continues to prioritize execution quality.

In parallel with these operational developments, the Board has continued to focus on governance and its own evolution to ensure appropriate oversight during this period of transition. Over the past year, the Board has remained attentive to matters of composition, refreshment, and skill alignment, with an emphasis on maintaining a mix of experience relevant to Shimmick's project profile, risk environment, and strategic direction. The Board has also continued to refine its oversight approach, including its engagement with management on strategy, capital allocation, operational risk, and financial performance. As Shimmick advances its transformation and narrows its focus on core capabilities, the Board believes that effective governance, clear accountability, and constructive engagement between directors and management remain essential to supporting long-term stockholder value.

The formal Notice of Annual Meeting and Proxy Statement are enclosed with this letter. The Proxy Statement describes the matters to be acted upon at the Annual Meeting. It also describes how the Board operates and provides compensation and other information about the management team and Board.

Your vote is important. Whether or not you plan to attend the Annual Meeting, I strongly encourage you to vote as soon as possible. You may vote over the Internet, by telephone or by mailing a proxy or voting instruction card. For instructions on voting, please refer to the Notice of Internet Availability of Proxy Materials you received in the mail or the section entitled "How do I vote?" on page 5 of the Proxy Statement. If you received a paper copy of the Proxy Statement, please use your enclosed proxy card to vote.

On behalf of the Board and the officers and employees of Shimmick Corporation, I would like to take this opportunity to thank you for your continued support of our company. We look forward to seeing you at the meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•<u>www.virtualshareholdermeeting.com/SHIM2026</u>

***What is the purpose of the annual meeting?***

At the annual meeting, stockholders will act upon the matters outlined in the notice of meeting on the cover page of this proxy statement, consisting of

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.election of the five nominees named in this Proxy Statement as directors for terms expiring at the 2027 Annual Meeting of Stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.ratification of the selection of Deloitte & Touche LLP ("Deloitte") as the Company's independent registered public accounting firm for Fiscal 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.any other matters that properly come before the meeting.

***Who is entitled to vote at the meeting?***

Only our stockholders of record at the close of business on April 20, 2026, the record date for the meeting, are entitled to receive notice of and to participate in the Annual Meeting. If you were a stockholder of record on that date, you will be entitled to vote all of the shares you held on that date at the meeting, or any postponement(s) or adjournment(s) of the meeting. As of the record date, there were 36,300,928 shares of common stock outstanding, all of which are entitled to be voted at the Annual Meeting.

***What are the voting rights of the holders of our common stock?***

Holders of common stock are entitled to one vote per share on each matter that is submitted to stockholders for approval.

***Who can attend the meeting?***

All stockholders as of the record date, or their duly appointed proxies, may attend the meeting, and each may be accompanied by one guest. Please also note that if you hold your shares in "street name" (that is, through a broker or other nominee), you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the record date.

***What constitutes a quorum and why is a quorum required?***

A quorum is required to transact business at the Annual Meeting. The holders of a majority of the outstanding shares of common stock as of the record date, present in person or represented by proxy and entitled to vote, will constitute a quorum. Proxies received but marked as abstentions, if any, proxies returned without making any selections, if any, and broker non-votes (described below) will be included in the calculation of the number of shares considered to be present at the meeting for quorum purposes. If we do not have a quorum, we will reconvene the Annual Meeting at a later date.

***What is the difference between a stockholder of record and a beneficial owner?***

If your shares are registered directly in your name with Shimmick's transfer agent, Equiniti Trust Company, you are considered the "stockholder of record" with respect to those shares.

------

If your shares are held by a brokerage firm, bank, trustee or nominee, you are considered the "beneficial owner" of shares held in street name. Notice of Internet Availability of Proxy Materials ("Notice") has been forwarded to you by your nominee who is considered the "stockholder of record" with respect to those shares. As the beneficial owner, you have the right to direct your nominee on how to vote your shares by following its instructions for voting.

***How do I vote?***

To be valid, your vote by Internet, telephone or mail must be received by the deadline specified on the proxy card or voting information form, as applicable. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting.

The inspector of election for the Annual Meeting shall determine the number of shares of common stock represented at the meeting, the existence of a quorum and the validity and effect of proxies, and shall count and tabulate ballots and votes and determine the results thereof. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining a quorum. A "broker non-vote" will occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary power with respect to that proposal and has not received instructions from the beneficial owner. Other than Proposal 2, none of the proposals described in this Proxy Statement are related to "routine" matters. As a result, a broker will not be able to vote your shares with respect to Proposal 1 absent your voting instructions.

Pursuant to our Corporate Governance Guidelines, any nominee in an election who fails to receive the required vote for re-election must tender such director's irrevocable offer of resignation for consideration by the Nominating and Corporate Governance Committee (the "Governance Committee") who will recommend to the Board the action to be taken.

***What if I sign and return my proxy without making any selections?*** 

If you sign and return your proxy without making any selections, your shares will be voted "**FOR**" each of the five director nominees in Proposal 1 and "FOR" Proposal 2. If other matters properly come before the meeting, Messrs. Ural Yal and John P. Carpenter will have the authority to vote on those matters for you at their discretion. As of the date of this Proxy Statement, we are not aware of other business to be acted upon at the Annual Meeting other than as disclosed in this Proxy Statement

***What if I abstain from voting on a proposal?*** 

If you sign and return your proxy marked "**ABSTAIN**" on any proposal, your shares will not be voted on that proposal and will not be counted as votes cast in the final tally of votes with regard to that proposal. However, your shares will be counted for purposes of determining whether a quorum is present.

***Can I change my vote after I return my proxy card?***

Yes. The giving of a proxy does not eliminate the right to vote in person should any stockholder giving the proxy so desire. Stockholders have an unconditional right to revoke their proxy at any time prior to the exercise of that proxy, by voting in person at the Annual Meeting, by filing a written revocation or duly executed proxy bearing a later date with our Secretary at our headquarters.

***What does it mean if I receive more than one proxy card?***

If you receive more than one proxy card, it means that you hold shares of Shimmick in more than one account. To ensure that all your shares are voted, sign and return each proxy card.

Alternatively, if you vote by telephone or on the Internet, you will need to vote once for each proxy card you receive.

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

We will announce the results for the proposals voted upon at the Annual Meeting and publish final detailed voting results in a Form 8-K filed within four business days after the Annual Meeting.

***Who will count and certify the votes?***

Representatives of Broadridge and our Corporate Secretary will count the votes and certify the election results.

***Who pays for costs relating to the proxy materials and annual meeting of stockholders?***

------

The costs of preparing, assembling and mailing this proxy statement, the Notice of Annual Meeting of Stockholders and the enclosed Annual Report and proxy card, along with the cost of posting the proxy materials on a website, are to be borne by us. We have engaged Broadridge to assist us in the distribution of proxy materials and to provide voting and tabulation services for the Annual Meeting for an estimated cost of $12,000, plus expenses. Our directors, officers and employees may solicit proxies personally and by telephone, facsimile and other electronic means. They will receive no compensation in addition to their regular salaries. We may also request banks, brokers and other custodians, nominees and fiduciaries to forward copies of the proxy material to their principals and to request authority for the execution of proxies. We may reimburse these persons for their expenses in so doing.

***Who should I call with other questions?***

If you have additional questions about this Proxy Statement or the meeting or would like additional copies of this Proxy Statement or our Annual Report, please contact: Shimmick Corporation, 530 Technology Drive, Suite 300, Irvine, CA 92618, Attention: Investor Relations, Telephone: (949) 704-2350.

**proposal 1 - election of directors**

**_________________________________________________________**

Under our Bylaws, directors are elected for a one-year term expiring at the next annual meeting of stockholders or until his or her successor is elected and qualified. Upon the recommendation of the Governance Committee, our Board has nominated the following five current directors for re-election at the Annual Meeting: Mitchell B. Goldsteen, Geoffrey E. Heekin, Joseph A. Del Guercio, Peter Kravitz and Ural Yal (collectively, the "Director Nominees"). The Board has nominated each of these persons to serve as a director for a one-year term that will expire at the 2027 Annual Meeting of Stockholders or until his successor is elected and qualified, and each has consented to serve if elected. Steven E. Richards will retire from the Board, effective as of the Annual Meeting, and his term as director will expire at the Annual Meeting.

The Board would like to take this opportunity to express its sincere gratitude to Mr. Richards for his service and invaluable contributions to the Company over the last 45 years, which included serving as Chief Executive Officer from March 2020 through December 2024 and guiding the Company through its November 2023 initial public offering. Effective immediately following the Annual Meeting, the size of the Board will be reduced to five members.

We believe that each of our nominated directors possesses the experience, skills and qualities to fully perform his duties as a director and contribute to our success. Our directors were nominated because the Board believes each possesses the highest standards of personal integrity and interpersonal and communication skills, is highly accomplished in his field, has an understanding of the interests and issues that are important to our stockholders and is able to dedicate sufficient time to fulfilling his obligations as a director. Our directors as a group complement each other and each other's respective experiences, skills and qualities.

Each director's principal occupation and other pertinent information about the particular experiences, qualifications, attributes and skills that led the Board to conclude that such person should serve as a director appears as follows.

**Corporate governance**

**_________________________________________________________**

The Board is committed to strong corporate governance. We believe strong corporate governance promotes the long-term interests of stockholders, strengthens board and management accountability and helps build public trust in our Company. The Board and its committees have adopted policies and processes that foster effective board oversight of critical matters such as strategy, risk management, including cybersecurity, financial and other controls, human capital and sustainability considerations, compliance and management succession planning. The Board reviews our major governance documents, policies and processes regularly in the context of current corporate governance trends, regulatory changes and recognized best practices, taking into consideration the perspectives of our stockholders. Through our website, *www.shimmick.com*, our stockholders have access to key corporate governance documents such as our Corporate Governance Guidelines, Business Code of Conduct and Ethics and charters of each committee of the Board.

The following sections provide an overview of our corporate governance structure, policies and processes, including key aspects of the Board operations.

**Board Structure and Composition** 

Our business and affairs are managed under the direction of our Board, which currently consists of six members. Effective immediately following the Annual Meeting, the size of the Board will be reduced to five members. Our Board is not classified, and each of our directors is subject to re-election annually.

The roles of Executive Chairman of the Board and Chief Executive Officer are separate. Our independent directors will meet separately in executive sessions on a regular basis, typically during a portion of, or immediately after, each regularly scheduled meeting of our Board. Mr. Goldsteen, our Executive Chairman presides at all meetings of the Board and of the stockholders. Our Corporate Governance Guidelines also provide that, when the position of Executive Chairman is not held by an independent director, an independent Lead Director will be appointed by the independent members of the Board. Mr. Kravitz currently serves as our Lead Director. As Lead Director, Mr. Kravitz serves as the liaison between the Executive Chairman and the independent directors. The Board believes that its current leadership structure is appropriate for the Company because it separates the leadership of the Board from the day-to-day leadership of the Company. The Board also believes that separating the position of Executive Chairman from Chief Executive Officer better positions the Board to evaluate the performance of management and enables the Executive Chairman to provide guidance to the Chief Executive Officer.

**Director Independence** 

The rules of Nasdaq require that a majority of our Board be independent. An "independent director" is defined generally as a person who, in the opinion of the Board, has no material relationship with the listed company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). Our Board has undertaken a review of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, our Board has determined that Mr. Heekin, Mr. Del Guercio and Mr. Kravitz qualify as "independent directors," as defined under the rules of Nasdaq. As required by Nasdaq listing standards, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present.

**Director Candidates**

The Governance Committee considers possible director nominee candidates from many sources, including management and stockholders. Detailed information regarding the procedures that our stockholders must follow to submit recommendations of director nominees, as well as the policies that the Board must follow to review such recommendations, can be found in Section 2.03 of Article II of our Bylaws.

------

The Governance Committee evaluates the suitability of potential candidates nominated by stockholders in the same manner as other candidates recommended to the Governance Committee. In identifying individuals to nominate for election to our Board, the Governance Committee, to the extent deemed relevant by the Governance Committee in its sole discretion, seeks candidates that, among other things, have:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•proven strength of integrity and character, sound, independent judgment, a track record of accomplishment in leadership roles and significant professional and corporate expertise, skills and experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•demonstrated notable or significant achievements in business, education or public service;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the requisite intelligence, education and experience to make a significant contribution to the Board and bring a range of skills, diverse perspectives and backgrounds to its deliberations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the highest ethical standards, a strong sense of professionalism and intense dedication to serving the interests of the stockholders.

Prior to the nomination of a director for re-election, the Governance Committee reviews the performance of each director whose term is expiring and determines whether that director should be nominated for election to an additional term following an assessment of the director's performance. If the Governance Committee or the Board decides to nominate a new candidate for election, the Governance Committee identifies the desired skills and experience of any new nominee in light of the criteria above.

In selecting Board nominees, the Governance Committee strives to maintain a board that reflects a diversity of experience and personal backgrounds. These criteria will vary over time depending on the needs of the Board. Accordingly, the Board may adopt new criteria and amend or abandon existing criteria as and when it determines such action to be appropriate.

If any member of the Board does not wish to continue in service or if the Governance Committee or the Board decides not to re-nominate a member for re-election, the Governance Committee will identify the desired skills and experience of a new nominee in light of the criteria above. Pursuant to our Corporate Governance Guidelines, any nominee in an election who fails to receive the required vote for re-election must tender such director's irrevocable offer of resignation for consideration by the Governance Committee who will recommend to the Board the action to be taken.

**Controlled Company Exemption** 

Because our controlling stockholder controls a majority of the voting power of our common stock, we are a "controlled company" for purposes of the listing standards of Nasdaq and the rules of the SEC. As a "controlled company", exemptions under the listing standards of Nasdaq exempt us from certain of Nasdaq's corporate governance requirements, including the following requirements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•that our Board be composed of a majority of "independent directors," as defined under the rules of Nasdaq,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•that our Compensation and Human Capital Committee (the "CHC Committee") be composed entirely of independent directors, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•that our Governance Committee be composed entirely of independent directors.

We currently rely on the "controlled company" exemption from the general Nasdaq requirements that our Board be composed of a majority of independent directors and that our CHC Committee be composed entirely of independent directors. However, effective upon the conclusion of the Annual Meeting, we will no longer rely on the "controlled company" exemption with respect to the requirement that our Board be composed of a majority of independent directors. Furthermore, currently, and effective upon the conclusion of the Annual Meeting, our Governance Committee is, and will continue to be, composed entirely of independent directors even though we are exempt from such Nasdaq requirement as a controlled company. The Board believes that utilizing the "controlled company" exemption with respect to our CHC Committee such that Mr. Goldsteen may serve on our CHC Committee, given Mr. Goldsteen's background and experience, is in the best interests of the Company and our stockholders at this time. The Board does not believe our reliance on the "controlled company" exemption will materially adversely affect the ability of our CHC Committee to act independently or to satisfy the other Nasdaq requirements or the rules promulgated under the Exchange Act.

The Board regularly evaluates our governance structure and will continue to assess whether changes to our approach are warranted as the Company evolves. Accordingly, for so long as we are a "controlled company," holders of our common stock may not have the same protections afforded to stockholders of companies that are subject to all of Nasdaq's corporate governance requirements to the extent we elect to take advantage of these exemptions. In the event that we cease to be a "controlled company", we will be required to comply with these provisions within the transition periods specified in the rules of Nasdaq. These exemptions do not modify the independence requirements for our Audit Committee, and we adhere to the member independence requirement for the Audit Committee.

------

**Board Committees** 

Our Board has three standing committees: the Audit Committee, the CHC Committee and the Governance Committee. The Board also established the Special Committee in May 2024 to oversee certain matters, including the budget and use of funds under our credit agreements, material and non-ordinary course asset sales and other transactions and certain compensation matters. All the current members of our Audit Committee, CHC Committee, Governance Committee and Special Committee are independent under applicable Nasdaq listing rules, except for Mr. Richards, who currently serves on the Governance Committee, but who will cease service on the committee effective upon the conclusion of the Annual Meeting, and Mr. Goldsteen, who currently serves on the CHC Committee and will continue to serve on the CHC Committee upon the conclusion of the Annual Meeting pursuant to "controlled company" exemption from the general Nasdaq requirement that our CHC Committee be composed entirely of independent directors. In addition, all the members of our Audit Committee are currently independent under Section 10A-3 of the Exchange Act and will continue to be upon the conclusion of the Annual Meeting. The charter for each of the committees is available on our website at *www.shimmick.com*.

Each member of the Board attended 100% of the meetings of the Board (six meetings in 2025) and the committees on which he served in 2025. The following table shows the members of each committee as of the end of the 2025 fiscal year, as well as the number of meetings held during the 2025 fiscal year.

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)The term of Mr. Richards will expire at the Annual Meeting.

Board members are generally expected to attend our annual meeting of stockholders, either in person, by phone or by other remote communication. All of the current members of the Board that were directors on the date of the 2025 Annual Meeting of Stockholders were present at the 2025 Annual Meeting of Stockholders.

*Audit Committee* 

The Audit Committee assists the Board in overseeing: (i) the integrity of our financial statements, (ii) our compliance with legal and regulatory requirements, (iii) the independence and qualifications of our independent registered public accounting firm, and (iv) the performance of our independent registered public accounting firm. The Audit Committee also reviews all related party transactions. Our Board has determined that each of Mr. Del Guercio and Mr. Kravitz is an audit committee financial expert within the meaning of the rules and regulations of the SEC. In addition, we must certify to Nasdaq that the audit committee has, and will continue to have, at least one member who has past employment experience in finance or accounting, requisite professional certification in accounting, or other comparable experience or background that results in the individual's financial sophistication. Our Board has determined that each of Mr. Del Guercio's, Mr. Heekin's and Mr. Kravitz's qualifications also satisfy Nasdaq's definition of financial sophistication.

*Compensation and Human Capital Committee* 

The CHC Committee reviews and approves the compensation of our Chief Executive Officer and our other executive officers and administers and makes recommendations to the Board with respect to the Shimmick Corporation 2023 Equity Incentive Plan (the "2023 Omnibus Incentive Plan") and any other compensation plans. In performing these duties, the CHC Committee also evaluates the performance of our Chief Executive Officer and oversees the performance evaluation of our other executive officers and key employees. In addition, the CHC Committee oversees the Company's human capital management, including the Company's policies with respect to performance management, talent management, an inclusive and equitable work culture and the development and retention of the Company's workforce.

*Nominating and Corporate Governance Committee* 

The Governance Committee assists the Board in identifying candidates qualified to become members of our Board, recommending a slate of nominees for election by the stockholders, recommending committee assignments for directors to the Board, overseeing the

------

evaluation of the Board and management and developing, updating and recommending to the Board appropriate corporate governance principles for the Company. In performing these duties, the Governance Committee also reviews and approves compensation for non-employee directors.

*Special Committee*

On May 20, 2024, we entered into a series of transactions (the "Transactions") with AECOM and Berkshire Hathaway Specialty Insurance Company ("BHSI"). The Transactions included, among other things, entry into a $60 million revolving credit facility (the "Credit Agreement"), a mutual release and settlement of certain claims with AECOM and a corresponding agreement to issue 7,745,000 shares of our common stock to AECOM, termination of the Financing Agreement, dated March 26, 2024, with BHSI and amendments to our previously existing Revolving Credit Facility, dated March 27, 2023, with MidCap Financial Services, LLC.

In connection with the Transactions, we also entered into a side letter to the Credit Agreement, which provides for, among other things, establishment of a special committee of independent directors (the "Special Committee"). The Special Committee is tasked with, among other things, overseeing the budget and use of funds under the Credit Agreement, material and non-ordinary course asset sales and other transactions and certain compensation matters. The Special Committee is comprised of three independent directors, with each of Shimmick, AECOM and BHSI selecting one director. Mr. Del Guercio, Mr. Kravitz and Mr. Heekin have currently been selected to serve as the designees for Shimmick, AECOM and BHSI, respectively.

**Code of Ethics / Related Party Transaction Policy**

Our Board adopted a code of ethics that applies to all of our directors, officers and employees, including our Chief Executive Officer and Chief Financial Officer. Our code of ethics prohibits all conflicts of interest unless they have been approved or ratified by a majority of the independent directors on our Board (or an authorized committee of our Board). This code of ethics is available on our website at www.shimmick.com, and we will disclose any future amendments or waivers of certain provisions of our code of ethics on our website in a Current Report on Form 8-K, as legally required.

The Company's legal staff, in consultation with the Company's finance team, determines, based on the facts and circumstances, whether each known transaction, arrangement and relationship in which the Company and a related party are participants constitutes a related parties transaction requiring compliance with our Related Party Transactions Policy. Our Related Party Transactions Policy provides that our Audit Committee must approve (or if the Audit Committee includes one or more directors with a material financial interest in the related party transaction, then the majority of the members of the Board who are not interested parties), in advance (to the extent feasible), all related party transactions involving any executive officer, Board member, Board nominee or beneficial owner of more than 5% of any class of the Company's voting securities or their immediate family members or any entity in which any of the foregoing persons is employed or has a 5% or greater beneficial ownership interest. If advance approval is not feasible, then the related party transaction may be preliminarily entered into by management upon prior approval of the transaction by the Chairperson of the Audit Committee (as long as the Chairperson is not an interested party) subject to ratification of the transaction by the Audit Committee (or, if applicable, the disinterested directors). Current SEC rules define transactions with related parties to include any transaction, arrangement or relationship (i) in which the Company is a participant, (ii) in which the amount involved exceeds $120,000, and (iii) in which any executive officer, director, director nominee, beneficial owner of more than 5% of the Company's common stock, or any immediate family member of such persons has or will have a direct or indirect material interest. All directors must recuse themselves from any discussion or decision affecting their personal, business or professional interests. All related party transactions will be disclosed in our applicable SEC filings as required under SEC rules.

**Board Role in Management of Risk**

The Board is actively involved in the oversight and management of risks that could affect the Company. Oversight and management are conducted primarily through the committees, but the full Board has retained responsibility for general oversight of risks. The Audit Committee is primarily responsible for overseeing the risk management and risk assessment function. In carrying out its responsibilities, the Audit Committee reviews our policies and processes with respect to risk assessment and risk management, and discusses with management and Deloitte our major financial and critical accounting practice risk exposures, as well as data privacy, security and cybersecurity risk exposure, and the steps management has taken to monitor and control such exposures. The Board believes that the administration of its risk oversight function has not affected its leadership structure.

**Anti-Hedging Policy**

Our directors and certain other senior officers are prohibited from pledging the Company's securities as collateral for a loan or hedging Company securities. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put option or put equivalent position or call option or call

------

equivalent position) with respect to any Company securities or with respect to any security that includes, relates to, or derives any significant part of its value from such securities.

**Insider Trading Policy**

We have adopted an insider trading policy (the "Insider Trading Policy") that governs the purchase and sale of our securities by employees, directors, officers of Shimmick and its subsidiaries and certain other persons that are subject to the policy on account of having access to material nonpublic information. We believe our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules, and regulations as well as the exchange listing standards applicable to us. Our Insider Trading Policy prohibits our employees, directors, officers and other persons subject to the policy from, either directly or indirectly through family members or other persons or entities, (i) engaging in or recommending to others transactions in securities while in possession of material, non-public information relating to the securities, whether the issuer of such security is Shimmick or any other company and (ii) directly or indirectly communicating material, nonpublic information to anyone outside of Shimmick (except in accordance with our policies regarding the protection or authorized external disclosure of our information) or to anyone within Shimmick other than on a need-to-know basis, among other things. In addition, it is our intent to comply with applicable laws and regulations relating to trading in our securities.

In addition to the above restrictions, our Insider Trading Policy requires that members of our Board and certain senior officers pre-clear every transaction involving our securities with our Corporate Secretary. Pre-clearance obligations apply to all transactions in the Company's securities, including without limitation, acquisitions and dispositions of Shimmick stock and gifts. Additionally, members of our Board, certain of our officers and other employees with regular access to material, non-public information are prohibited from trading in Shimmick securities during certain blackout periods, except pursuant to a trading plan intended to comply with Securities and Exchange Commission (the "SEC") Rule 10b5-1 that is entered into and maintained in compliance with our Insider Trading Policy and applicable law. The foregoing summary of our Insider Trading Policy does not purport to be complete and is qualified by reference to our Insider Trading Policy, a copy of which can be found as an exhibit to our Annual Report.

**Practices Related to Timing of Equity Grants**

Neither the Board nor the CHC Committee takes into account material non-public information when determining the timing or terms of equity awards, nor do we time disclosure of material non-public information for the purpose of affecting the value of executive compensation. During fiscal year 2025, we did not grant stock options to any executive officer during any period beginning four business days before and ending one business day after the filing of any periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any current report on Form 8-K that disclosed material non-public information.

<br>**Sustainability and Corporate Responsibility** 

***Environmental***

Our work contributes to addressing the nation's need for reliable and resilient infrastructure, particularly in water end-markets. Our water infrastructure projects incorporate systems for treating and repurposing wastewater, which can help reduce strain on freshwater resources.

We also construct projects that are designed to protect regions from flooding. We build flood control systems to mitigate the impact of sea-level rise and flooding events on communities. Additionally, our work along the nation's inland waterways supports efficient transportation of goods.

Our projects are often constructed in environmentally sensitive areas and urban locations where minimizing negative impacts of construction on the community is a priority. Our Safety, Health, and Environmental ("SH&E") program includes specific guidelines to protect people and the environment and minimize impacts of construction activities.

***Social*** 

Our focus on corporate responsibility is not limited to sustainability. We also prioritize social responsibility across our operations and deploy operational best practices across all of our projects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Safety*. Safety is a core Shimmick value. We begin meetings with safety messages and conduct ongoing training programs that reinforce hazard awareness and safe work practices. All new employees undergo an initial safety orientation, and for certain types of projects, we conduct specific hazard training programs. Our project foremen and superintendents conduct regular on-site safety meetings, and our safety professionals perform site inspections and provide additional training when needed. In addition, our superintendents and project managers are required to complete OSHA-approved safety training. For the 2025 fiscal year, our total recordable incident rate ("TRIR") was 1.39 incidents per 100 full-time equivalent

------

employees. While our TRIR increased compared to the prior year, we achieved a 33.3% reduction in our lost time incident rate in the 2025 fiscal year, reflecting continued emphasis on reducing more serious injuries and maintaining safe jobsite conditions. During the 2025 fiscal year, we had no Occupational Safety and Health Administration ("OSHA") or Environmental Protection Agency ("EPA") citations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Harassment-Free Work Environment*. We are committed to an inclusive and equitable workplace, with a culture where employees are treated with respect. All our employees are responsible for maintaining a respectful workplace free of unlawful discrimination, harassment, and retaliation. We maintain an ethics hotline that employees can use to report incidents confidentially and without fear of retaliation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Business Partners*. We regularly partner with disadvantaged business enterprises to provide subcontracting opportunities. We have a team of small business program managers. We provide an outreach program that includes a mentor-protégé program.

***Governance*** 

Our governance framework is designed to promote transparency, ethical conduct, and accountability. Our board of directors comprises directors who provide strategic guidance and oversight and our executive management team is responsible for implementing our governance principles.

**Director Compensation** 

*Annual Retainer* 

The annual retainer fees for fiscal 2025 for our non-executive directors are set forth below, payable in cash. We do not pay meeting fees to our non-employee directors. Annual retainer fees are payable quarterly in arrears.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•An annual equity retainer of restricted stock units in the amount of $150,000;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•$90,000 for each non-employee director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•an additional $25,000 for the Lead Director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•an additional $5,000 for the Chairman of the Governance Committee; $2,500 for each member;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•an additional $12,000 - $170,000 for each member of the Special Committee.

*Expense Reimbursement* 

We reimburse directors for travel expenses related to attending Board and committee meetings and for other company related business. In certain circumstances, we may also invite director spouses to accompany directors to some of our Board meetings, for which we pay or reimburse travel expenses.

*2025 Director Compensation*

The following table sets forth the compensation paid in 2025 to each non-employee director.

**proposa** **l 2 - RATIFICATION OF INDEPENDENT** 

**REGISTERED PUBLIC ACCOUNTING FIRM**

**_________________________________________________________**

The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of Shimmick's independent registered public accounting firm. To execute this responsibility, the Audit Committee engages in a comprehensive annual evaluation of the independent registered public accounting firm's qualifications, performance and independence and whether the independent registered public accounting firm should be rotated, and considers the advisability and potential impact of selecting a different independent registered public accounting firm.

Deloitte & Touche LLP ("Deloitte") audited our consolidated financial statements for the 2025 and 2024 fiscal years. As discussed below, our Audit Committee, which has sole and direct responsibility for the appointment, compensation, oversight, evaluation, retention and termination of any independent registered public accounting firm engaged by the Company, considers Deloitte to be well qualified and has appointed Deloitte as our independent registered public accounting firm to audit our consolidated financial statements for Fiscal 2026. This proposal asks you to ratify the Audit Committee's appointment of Deloitte as our independent registered public accounting firm. Although ratification is not required by our Bylaws or otherwise, the Board is submitting the selection of Deloitte to our stockholders for ratification because we value our stockholders' views on the Company's independent registered public accounting firm and as a matter of good corporate practice.

The Audit Committee, along with senior management, reviewed Deloitte's performance as part of its consideration of whether to re-appoint Deloitte as our independent registered public accounting firm. As part of this review, the Audit Committee considered, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deloitte's independence and objectivity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the communication and interaction with our Deloitte team over the course of the prior year,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the breadth and complexity of our business and its national footprint and the resulting demands placed on the auditing firm;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•external data and management's perception relating to the depth and breadth of Deloitte's auditing qualification and experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deloitte's historical and recent performance; recent Public Company Accounting Oversight Board (United States) ("PCAOB") inspection reports on the firm;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the length of time that Deloitte has served as our independent registered public accounting firm; the quantity and quality of Deloitte's staff and national reach; the appropriateness of Deloitte's fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•and the potential impact of changing our independent registered public accounting firm.

The Audit Committee recognized the ability of Deloitte to provide both the necessary expertise to audit our business and the matching national footprint to audit the Company nationwide, as well as other factors, including the policies that Deloitte follows with respect to the rotation of its key audit personnel so that there is a new partner-in-charge at least every five years. The Audit Committee is involved in the selection of the new partner-in charge of the audit engagement when there is a rotation.

Based on the results of its review, the Audit Committee concluded that Deloitte is independent and objective and that it is in the best interests of the Company and its stockholders to appoint Deloitte to serve as the Company's independent registered public accounting firm for Fiscal 2026. Consequently, the Audit Committee has appointed Deloitte as the Company's independent registered public accounting firm for Fiscal 2026, and the Board is recommending that the Company's stockholders ratify this appointment.

If the Company's stockholders do not ratify the selection, the Audit Committee will reconsider whether or not to retain Deloitte but may, nonetheless, choose to retain Deloitte as the Company's independent registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may change the appointment at any time if it determines that such change would be in the best interests of the Company and its stockholders.

A representative of Deloitte is expected to be present at the Annual Meeting, will have the opportunity to make a statement if he or she desires and also will be available to respond to appropriate questions.

**<u>Required Vote</u>** 

Ratification of the appointment of Deloitte as the Company's independent registered public accounting firm requires the affirmative vote of the holders of a majority of the votes cast, either in person or by proxy, at the Annual Meeting.

<br>**Recommendation of the Board of Directors** <br>The Board unanimously recommends a vote "**FOR**" ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for Fiscal 2026. <br>

**Pre-Approval Policies and Procedures for Audit and Permitted Non-Audit Services** 

The Pre-Approval Policy of the Company provides that the Audit Committee is required to pre-approve all audit and non-audit services performed by the Company's independent auditor in order to assure that the provision of such services does not impair the auditor's independence. Any proposed services exceeding pre-approved cost levels require specific pre-approval by the Audit Committee. The term of any pre-approval is twelve months from the date of pre-approval, unless the Audit Committee specifically provides for a different period or amends such approval.

Pursuant to the Pre-Approval Policy, the Audit Committee may delegate pre-approval authority to the one or more members of the Audit Committee. The member or members to whom such authority is delegated must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee may not delegate its responsibilities to pre-approve services performed by the independent auditor to management.

Consistent with these policies and procedures, the Audit Committee approved all of the services rendered by Deloitte during fiscal year 2025 requiring approval as described above.

**Audit Committee Report**

The Audit Committee of the Board of Directors is responsible for providing independent, objective oversight of the Company's accounting functions and internal controls. The Audit Committee is composed of three directors, each of whom is independent as defined by the Nasdaq listing rules. The Audit Committee operates under a written charter approved by the Board of Directors and

------

held four meetings in fiscal 2025. A copy of the charter is available on the Company's website at www.shimmick.com by choosing the "Investors" link then clicking on the "Governance" section.

Management is responsible for the Company's internal controls over financial reporting, disclosure controls and procedures and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of the Company's consolidated financial statements. The Audit Committee's responsibility is to monitor and oversee both processes. The Audit Committee has established a mechanism to receive, retain and process complaints on auditing, accounting and internal control issues, including the confidential, anonymous submission by employees, vendors, customers and others of concerns on questionable accounting and auditing matters.

In connection with these responsibilities, the Audit Committee met with management and the independent registered public accounting firm to review and discuss the January 2, 2026 audited consolidated financial statements. The Audit Committee also discussed with the independent registered public accounting firm the matters required by Statement on Auditing Standards Update No. 61, as amended (AICPA, Professional Standards, Vol. 1, AU section 380), as adopted by the PCAOB in Rule 3200T. In addition, the Audit Committee received the written disclosures from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence, and the Audit Committee has discussed the independent registered public accounting firm's independence from the Company and its management.

Based upon the Audit Committee's discussions with management and the independent registered public accounting firm, and the Audit Committee's review of the representations of management and the independent registered public accounting firm, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company's Annual Report.

The Audit Committee also has appointed, subject to stockholder ratification, Deloitte as the Company's independent registered public accounting firm for Fiscal 2026.

We mailed the Notice containing instructions on how to access our proxy statement and annual report online on or about April 22, 2026. If you would like to receive a paper copy of the proxy materials, the Notice contains instructions on how to receive a paper copy.

**Householding** 

We have adopted a procedure approved by the SEC called "householding." Under this procedure, stockholders of record who have the same address and last name will receive only one copy of our Notice, unless one or more of these stockholders notifies us that they wish to continue receiving individual copies. This procedure will reduce our printing costs and postage fees.

If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the Notice, or if you hold stock in more than one account, and in either case you wish to receive only a single copy of the Notice for your household, please contact our Corporate Secretary at Shimmick Corporation, 530 Technology Drive, Suite 300, Irvine, CA 92618, (949) 704-2350.

If you participate in householding and wish to receive a separate copy of the Notice, or if you do not wish to participate in householding and prefer to receive separate copies of the Notice in the future, please contact our Corporate Secretary as indicated above. Beneficial owners of shares can request information about householding from their nominee.
