Exhibit 10.12

November 20, 2019

Mr. Tom Rohrs

[XXXXX]

[XXXXX]

Dear Tom:

On behalf of Ichor Holdings, Ltd. (the “Company”), we would like to formally confirm our offer to you to serve as chairman (“Executive Chairman”) of the board of directors of the Company (the “Board”). This letter agreement (this “Agreement”) supersedes and replaces that certain Employment Agreement by and between you, Ichor Systems, Inc. and the Company, dated as of September 19, 2014 (the “Prior Agreement”), which, other than as set forth herein, shall be terminated in connection with this Agreement; provided, that, you agree that nothing contained in this Agreement shall constitute grounds for your resignation with Good Reason (as defined in the Prior Agreement).

As a member of the Board, you will be involved in the oversight of the Company and its subsidiaries. We strongly believe that the Company will benefit from your involvement and are looking forward to working with you in the future. This letter will provide you with information relating to your service as Executive Chairman of the Board, the compensation associated with such service, conditions applicable to our offer, and the other terms of your Board membership.

Duties: It is our understanding that you are familiar, in a general way, with the duties and obligations associated with board membership at public companies, and we will not attempt to review those responsibilities in this letter. However, as a practical matter, the Executive Chairman is generally responsible for oversight of the Board on a day-to-day basis.

Conflicts of Interest: You shall immediately disclose to the Company any conflict of interest that arises in relation to your service as Executive Chairman as a result of any present or future appointment, employment or other engagement.

Start Date: You will commence service as Executive Chairman on January 6, 2020, or such other date as mutually agreed between you and the Company (the “Start Date”).

Term: You agree to serve as Executive Chairman for an initial term of one year. The Company may extend your term as Executive Chairman on a year-by-year basis.

Cash Compensation for Board Service: You will be entitled to the following compensation in connection with your acceptance of the position as Executive Chairman, commencing as of the Start Date:

The Company may withhold (or cause there to be withheld, as the case may be) from any amounts otherwise due or payable under or pursuant to this letter agreement such federal, state and local income, employment, or other taxes or other amounts as may be required to be withheld pursuant to any applicable law or regulation.

Termination. Upon your separation from service with the Company for any reason, all compensation and benefits due to you shall be governed by the Company’s Select Severance Plan, in which you will participate as an Eligible Employee and, for avoidance of doubt, not as the Chief Executive Officer.

D&O Insurance. As a director of the Company, you will be covered by the Directors & Officers Liability insurance policy of the Company. This policy protects directors and officers of the Company from liability in the event of a claim or lawsuit against them alleging wrongdoing in connection with the Company’s business. This policy does not cover fines and penalties once a verdict of dishonesty or fraud by a court of law or other regulatory body has been made against the director.

Confidentiality. You hereby agree that, notwithstanding anything contained herein to the contrary, the restrictions, commitments and covenants set forth in Section 6 of the Prior Agreement shall survive the termination thereof and shall be incorporated into this Agreement by reference.

General: This Agreement supersedes any conversations we may have had about your service as Executive Chairman or compensation as a Board member, or any written materials previously provided to you relating to this subject. Further, this letter, if accepted by you, will represent our entire agreement relating to your service on the Board, subject only to written amendment. This Agreement resulting from its acceptance shall be governed by United States Law and any disputes arising or relating to the same shall be heard and determined only by a court sitting in Delaware.
