Exhibit 10.2.1

FABRINET

2010 PERFORMANCE INCENTIVE PLAN

(As amended December 20, 2010, December 20, 2012, and June 26, 2014)

The purpose of this Fabrinet 2010 Performance Incentive Plan (this “Plan”) of Fabrinet, an exempted company formed under the laws of the Cayman Islands (the “Company”), is to promote the success of the Company and to increase shareholder value by providing an additional means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons.

The Administrator (as such term is defined in Section 3.1) may grant awards under this Plan only to those persons that the Administrator determines to be Eligible Persons. An “Eligible Person” is any person who is either: (a) an officer (whether or not a director) or employee of the Company or one of its Subsidiaries; (b) a director of the Company or one of its Subsidiaries; or (c) an individual consultant or advisor who renders or has rendered bona fide services (other than services in connection with the offering or sale of securities of the Company or one of its Subsidiaries in a capital-raising transaction or as a market maker or promoter of securities of the Company or one of its Subsidiaries) to the Company or one of its Subsidiaries and who is selected to participate in this Plan by the Administrator; provided, however, that a person who is otherwise an Eligible Person under clause (c) above may participate in this Plan only if such participation would not adversely affect either the Company’s eligibility to use Form S-8 to register under the Securities Act of 1933, as amended (the “Securities Act”), the offering and sale of shares issuable under this Plan by the Company or the Company’s compliance with any other applicable laws. An Eligible Person who has been granted an award (a “participant”) may, if otherwise eligible, be granted additional awards if the Administrator shall so determine. As used herein, “Subsidiary” means any corporation or other entity a majority of whose outstanding voting shares or voting power is beneficially owned directly or indirectly by the Company; and “Board” means the Board of Directors of the Company.

With respect to awards intended to satisfy the requirements for performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), this Plan shall be administered by a committee consisting solely of two or more outside directors (as this requirement is applied under Section 162(m) of the Code); provided, however, that the failure to satisfy such requirement shall not affect the validity of the action of any committee otherwise duly authorized and acting in the matter. Award grants, and transactions in or involving awards, intended to be exempt under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), must be duly and timely authorized by the Board or a committee consisting solely of two or more non-employee directors (as this requirement is applied under Rule 16b-3 promulgated under the Exchange Act). To the extent required by any applicable securities exchange, this Plan shall be administered by a committee composed entirely of independent directors (within the meaning of the applicable listing agency).

5.1.1 Share Options. A share option is the grant of a right to purchase a specified number of Ordinary Shares during a specified period as determined by the Administrator. An option may be intended as an incentive stock option within the meaning of Section 422 of the Code (an “ISO”) or a nonqualified share option (an option not intended to be an ISO). The award agreement for an option will indicate if the option is intended as an ISO; otherwise it will be deemed to be a nonqualified share option. The maximum term of each option (ISO or nonqualified) shall be ten (10) years. The per share exercise price for each option shall be not less than 100% of the fair market value of an Ordinary Share on the

5

date of grant of the option. When an option is exercised, the exercise price for the shares to be purchased shall be paid in full in cash or such other method permitted by the Administrator consistent with Section 5.4. Unless otherwise set forth in the applicable award agreement, options will be scheduled to vest as to twenty-five (25%) of the shares granted under the award on each annual anniversary of the award’s grant date over a period of four (4) years, subject to the award recipient’s continued employment or other service with the Company or its Subsidiaries through each applicable vesting date.

5.1.2 Additional Rules Applicable to ISOs. To the extent that the aggregate fair market value (determined at the time of grant of the applicable option) of shares with respect to which ISOs first become exercisable by a participant in any calendar year exceeds $100,000, taking into account both Ordinary Shares subject to ISOs under this Plan and shares subject to ISOs under all other plans of the Company or one of its Subsidiaries (or any parent or predecessor corporation to the extent required by and within the meaning of Section 422 of the Code and the regulations promulgated thereunder), such options shall be treated as nonqualified share options. In reducing the number of options treated as ISOs to meet the $100,000 limit, the most recently granted options shall be reduced first. To the extent a reduction of simultaneously granted options is necessary to meet the $100,000 limit, the Administrator may, in the manner and to the extent permitted by law, designate which Ordinary Shares are to be treated as shares acquired pursuant to the exercise of an ISO. ISOs may only be granted to employees of the Company or one of its subsidiaries (for this purpose, the term “subsidiary” is used as defined in Section 424(f) of the Code, which generally requires an unbroken chain of ownership of at least 50% of the total combined voting power of all classes of shares of each subsidiary in the chain beginning with the Company and ending with the subsidiary in question). There shall be imposed in any award agreement relating to ISOs such other terms and conditions as from time to time are required in order that the option be an “incentive stock option” as that term is defined in Section 422 of the Code. No ISO may be granted to any person who, at the time the option is granted, owns (or is deemed to own under Section 424(d) of the Code) outstanding Ordinary Shares possessing more than 10% of the total combined voting power of all classes of shares of the Company, unless the exercise price of such option is at least 110% of the fair market value of the shares subject to the option and such option by its terms is not exercisable after the expiration of five (5) years from the date such option is granted.

5.1.3 Share Appreciation Rights. A share appreciation right or “SAR” is a right to receive a payment, in cash and/or Ordinary Shares, equal to the excess of the fair market value of a specified number of Ordinary Shares on the date the SAR is exercised over the “base price” of the SAR, which base price shall be set forth in the applicable award agreement and shall be not less than 100% of the fair market value of an Ordinary Share on the date of grant of the SAR. The maximum term of an SAR shall be ten (10) years. Unless otherwise set forth in the applicable award agreement, SAR awards will be scheduled to vest as to twenty-five (25%) of the shares granted under the award on each annual anniversary of the award’s grant date over a period of four (4) years, subject to the award recipient’s continued employment or other service with the Company or its Subsidiaries through each applicable vesting date.

6

5.1.4 Other Awards. The other types of awards that may be granted under this Plan include: (a) share bonuses, restricted shares, performance shares, share units, phantom shares, dividend equivalents, or similar rights to purchase or acquire shares, whether at a fixed or variable price or ratio related to the Ordinary Shares, upon the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions, or any combination thereof; or (b) any similar securities with a value derived from the value of or related to the Ordinary Shares and/or returns thereon. Unless otherwise set forth in the applicable award agreement, such awards will be scheduled to vest as to twenty-five (25%) of the shares granted under the award on each annual anniversary of the award’s grant date over a period of four (4) years, subject to the award recipient’s continued employment or other service with the Company or its Subsidiaries through each applicable vesting date.

7

In no event shall any shares newly-issued by the Company be issued for less than the minimum lawful consideration for such shares or for consideration other than consideration permitted by applicable state law. Ordinary Shares used to satisfy the exercise price of an option shall be valued at their fair market value on the date of exercise. The Company will not be obligated to deliver any shares unless and until it receives full payment of the exercise or purchase price therefor and any related withholding obligations under Section 8.5 and any other conditions to exercise or purchase have been satisfied. Unless otherwise expressly provided in the applicable award agreement, the Administrator may at any time eliminate or limit a participant’s ability to pay the purchase or exercise price of any award or shares by any method other than cash payment to the Company.

8

5.6.1 Limitations on Exercise and Transfer. Unless otherwise expressly provided in (or pursuant to) this Section 5.6 or required by applicable law, (a) all awards are non-transferable and shall not be subject in any manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or charge; (b) awards shall be exercised only by the participant; and (c) amounts payable or shares issuable pursuant to any award shall be delivered only to (or for the account of) the participant.

5.6.2 Exceptions. The Administrator may permit awards to be exercised by and paid to, or otherwise transferred to, family members (or trusts or other entities on their behalf) or charitable organizations or entities pursuant to such conditions and procedures, including limitations on subsequent transfers, as the Administrator may, in its sole discretion, establish in writing. Any permitted transfer shall be subject to compliance with applicable federal and state securities laws and shall not be for value (other than nominal consideration, settlement of marital property rights, or for interests in an entity in which more than 50% of the voting interests are held by the Eligible Person or by the Eligible Person’s family members).

5.6.3 Further Exceptions to Limits on Transfer. The exercise and transfer restrictions in Section 5.6.1 shall not apply to:

Unless otherwise expressly provided in the applicable award agreement, upon (or, as may be necessary to effect the adjustment, immediately prior to) any event or transaction described in the preceding paragraph or a sale of all or substantially all of the business or assets of the Company as an entirety, the Administrator shall equitably and proportionately adjust the performance standards applicable to any then-outstanding performance-based awards to the extent necessary to preserve the level of incentives intended by this Plan and the then-outstanding performance-based awards.

It is intended that, if possible, any adjustments contemplated by the preceding two paragraphs be made in a manner that satisfies applicable U.S. legal, tax (including, without limitation and as applicable in the circumstances, Section 424 of the Code and Section 409A of the Code) and accounting (so as to not trigger any charge to earnings with respect to such adjustment) requirements.

Without limiting the generality of Section 3.3, any good faith determination by the Administrator as to whether an adjustment is required in the circumstances pursuant to this Section 7.1, and the extent and nature of any such adjustment, shall be conclusive and binding on all persons.

11

Without limiting the preceding paragraph, in connection with any event referred to in the preceding paragraph or any change in control event defined in any applicable award agreement, the Administrator may, in its discretion, provide for the accelerated vesting of any award or awards as and to the extent determined by the Administrator in the circumstances.

The Administrator may adopt such valuation methodologies for outstanding awards as it deems reasonable in the event of a cash or property settlement and, in the case of options, SARs or similar rights, but without limitation on other methodologies, may base such settlement solely upon the excess if any of the per share amount payable upon or in respect of such event over the exercise or base price of the award.

In any of the events referred to in this Section 7.2, the Administrator may take such action contemplated by this Section 7.2 prior to such event (as opposed to on the occurrence of such event) to the extent that the Administrator deems the action necessary to permit the participant to realize the benefits intended to be conveyed with respect to the underlying shares. Without limiting the generality of the foregoing, the Administrator may deem an acceleration to occur immediately prior to the applicable event and/or reinstate the original terms of the award if an event giving rise to an acceleration does not occur.

Notwithstanding the foregoing, to the extent a participant is subject to U.S. income taxation, a transaction will not be deemed to occur under this Section 7.2 unless the transaction qualifies as a change in control event within the meaning of Section 409A of the Code (“Section 409A”), as it has been and may be amended from time to time, and any proposed or final Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated thereunder from time to time.

12

Without limiting the generality of Section 3.3, any good faith determination by the Administrator pursuant to its authority under this Section 7.2 shall be conclusive and binding on all persons.

13

14

In any case where a tax is required to be withheld in connection with the delivery of Ordinary Shares under this Plan, the Administrator may in its sole discretion (subject to Section 8.1) require or grant (either at the time of the award or thereafter) to the participant the right to elect, pursuant to such rules and subject to such conditions as the Administrator may establish, that the Company reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their fair market value or at the sales price in accordance with authorized procedures for cashless exercises, necessary to satisfy the minimum applicable withholding obligation on exercise, vesting or payment. In no event shall the shares withheld exceed the minimum whole number of shares required for tax withholding under applicable law.

15

8.7.1 Effective Date. This Plan is effective as of the Registration Date. This Plan shall be submitted for and subject to shareholder approval no later than twelve months after the adoption of the Plan by the Board. Unless earlier terminated by the Board, this Plan shall terminate at the close of business on the day before the tenth anniversary of the adoption of the Plan by the Board. After the termination of this Plan either upon such stated expiration date or its earlier termination by the Board, no additional awards may be granted under this Plan, but previously granted awards (and the authority of the Administrator with respect thereto, including the authority to amend such awards) shall remain outstanding in accordance with their applicable terms and conditions and the terms and conditions of this Plan.

8.7.2 Board Authorization. The Board may, at any time, terminate or, from time to time, amend, modify or suspend this Plan, in whole or in part. No awards may be granted during any period that the Board suspends this Plan.

8.7.3 Shareholder Approval. To the extent then required by applicable law or any applicable listing agency or required under Sections 422 or 424 of the Code to preserve the intended tax consequences of this Plan, or pursuant to any repricing under Sections 3.2(g) and 3.2(j), or deemed necessary or advisable by the Board, any amendment to this Plan shall be subject to shareholder approval.

8.7.4 Amendments to Awards. Without limiting any other express authority of the Administrator under (but subject to) the express limits of this Plan, the Administrator by agreement or resolution may waive conditions of or limitations on awards to participants that the Administrator in the prior exercise of its discretion has imposed, without the consent of a participant, and (subject to the requirements of Sections 3.2 and 8.7.5) may make other changes to the terms and conditions of awards. Any amendment or other action that would constitute a repricing of an award is subject to the limitations set forth in Section 3.2(g).

8.7.5 Limitations on Amendments to Plan and Awards. No amendment, suspension or termination of this Plan or amendment of any outstanding award

16

8.9.1 Choice of Law. This Plan, the awards, all documents evidencing awards and all other related documents shall be governed by, and construed in accordance with the laws of the State of California.

8.9.2 Severability. If a court of competent jurisdiction holds any provision invalid and unenforceable, the remaining provisions of this Plan shall continue in effect.

8.9.3 Plan Construction. It is the intent of the Company that the awards and transactions permitted by awards be interpreted in a manner that, in the case of participants who are or may be subject to Section 16 of the Exchange Act, qualify, to the maximum extent compatible with the express terms of the award, for exemption from matching liability under Rule 16b-3 promulgated under the Exchange Act. Notwithstanding the foregoing, the Company shall have no liability to any participant for Section 16 consequences of awards or events under awards if an award or event does not so qualify.
