The Deferred Compensation Plan for Non-Employee Directors of Solstice Advanced Materials Inc. has been created to provide an opportunity for the non-employee Directors of Solstice Advanced Materials Inc. to defer compensation paid for services as a member of the Solstice Advanced Materials Inc. Board of Directors. The Plan is unfunded for tax purposes. Unless otherwise provided, the terms of the Plan are effective as of the Effective Date.

Each non-employee Director of the Board of Directors (the "Board") of Solstice Advanced Materials Inc. (the "Corporation") or any of its subsidiaries (a "Director") will receive Compensation for each year of service as a Director. In accordance with the terms of the Plan, the Director may elect to defer such Compensation.

(d)Compensation. A Director’s “Compensation” includes the annual cash retainer paid to a Director for services on the Board and any additional amounts that the Director may receive from the Corporation related to services as a Director. For the initial Plan Year, Compensation will only include amounts earned after March 31, 2026.

(a)Timing of Election. Prior to the beginning of any Plan Year, each Director who is not then participating in the Plan may elect to participate in the Plan by directing that all or any part of the Director's Compensation, which otherwise would be payable as Compensation for services as a Director during the upcoming Plan Year, be credited to the Director's Account in the Plan as Elective Deferrals (“Deferral Election”). Such Deferral Election must be made prior to the

(b)Newly Eligible Directors. Any Director providing services on the Effective Date of the Plan and any person who thereafter becomes a Director may elect, within thirty (30) days after the date the Director becomes eligible to participate in the Plan, to defer all or any part of the Director's Compensation paid for services performed for calendar quarters beginning after the date of the Deferral Election, consistent with the requirements of Treasury Regulation Section 1.409A-2(a)(7). If a Director does not make a Deferral Election with respect to a Plan Year by the specified date, the Director will be deemed to have elected to receive their Compensation in cash. When a Deferral Election is made with respect to a Plan Year, the Non-Employee Director may not revoke or change that Deferral Election with respect to such Plan Year.

(c)Form and Duration of Election. A Deferral Election shall be made by on an Election Form provided by the Plan Administrator, executed by the Director and then returned to the Plan Administrator. Such Deferral Election is irrevocable for the Plan Year to which it applies and shall continue in effect for the current Plan Year and for further Plan Years until it is affirmatively revoked. Any change or termination to the amount of Elective Deferrals being made to the Plan during a Plan Year shall become effective for the next Plan Year. In the event the Director ceases to make Elective Deferrals to the Plan, the amounts credited to the Director's Account prior to the cessation of Election Deferrals shall not be affected by the change and shall remain as part of the Director’s Account.

(d)Adjustment of Future Elective Deferrals. Prior to the beginning of any Plan Year, a Director may file a new written Election Form with the Plan Administrator changing the percentage of Elective Deferrals to be credited to the Director's Account for services as a Director in the upcoming Plan Year. Elections for a particular Plan Year must be made on or before December 31 of the prior Plan Year in order to be effective for the next Plan Year. An Elective Deferral election made for the current Plan Year is irrevocable and will not be affected by the new Elective Deferral change and will continue to be made in accordance with the Deferral Election in place for the respective Plan Year and for subsequent Plan Years until it is affirmatively revoked.

(a)Available Investment Options. Once a Director makes an election to make Elective Deferrals to the Plan, such amounts shall be credited to the Director’s Account and shall be hypothetically invested in one or more investment options made available by the Corporation from time to time in its discretion. and which may correspond with one or more investment funds in the Solstice Advanced Materials Deferred Compensation Plan (“DCP”). If an investment option under the Plan that mirrors an investment in the DCP changes or the timing of the crediting of interest under the DCP with respect to the investment changes, such change shall be automatically applied to the Plan. The investment options under the Plan are used solely to calculate the earnings that are credited to each Director's Account in accordance with Paragraph 5(b) below, and do not represent any beneficial interest on the part of the Director in any asset or other property of the Corporation. At the inception of the Plan, the sole investment fund shall be the Annual RateFund in the DCP.

(b)Crediting of Earnings/Losses. The Director’s Account shall be credited with earnings and losses, as applicable, commencing on the date each such Elective Deferral is credited to the Director’s Account in the Plan. Any interest or earnings on the Elective Deferrals credited to the Plan shall accrue daily and will be credited for bookkeeping purposes to the Director's Account as soon as administratively possible on or after the last day of the month. The Director's Account shall continue to be hypothetically invested in accordance with Paragraph 5(a) from the date initially credited to Plan until distributed in accordance with the Plan.

All Compensation which a Director elects to defer under the Plan shall be credited to the Director's Account. All credits shall be made as unfunded book entries and the Director shall not have any interest in any amounts credited to the Director's Account until distributed in accordance with the terms of the Plan.

(b)Beneficiary Designation. A Director may elect and/or change the designated beneficiary (or beneficiaries) at any time during the Director's lifetime by completing a Beneficiary Designation Form provided by the Plan Administrator and return such form to the Plan Administrator. A Beneficiary Designation Form is not considered valid unless it has been received by and approved by the Plan Administrator. If a Director fails to designate a beneficiary, then the Director’s designated Beneficiary shall be deemed to be the Director’s estate. If a Director is divorced, any beneficiary designation previously made by the Director that designated the Director’s former spouse as beneficiary shall automatically be revoked and, if the Director did not make a subsequent beneficiary election, all amounts owed to the Director under the Plan shall be made to the Director’s estate.

The Plan Administrator may allow a Director to withdraw all or a portion of the Director Account in the event of an Unforeseeable Emergency, as defined below, consistent with Code Section 409A. The amount withdrawn may not exceed the amount needed to satisfy the financial hardship, including applicable taxes payable on such amount.

Distribution on account of Unforeseeable Emergency may not be made to the extent that such emergency is or may be relieved through reimbursement or compensation from insurance or otherwise, by liquidation of the Director’s assets, to the extent the liquidation of such assets would not cause severe financial hardship, or by cessation of deferrals under the Plan, consistent with Code Section 409A. The Administrator may require cancellation of the Director’s current Elective Deferral election in the event of a distribution on account of Unforeseeable Emergency.

The Corporation intends for the Plan to comply with the requirements of Code Section 409A of the Code and shall be operated and interpreted consistent with that intent. In no event may a Director, directly or indirectly, designate the Plan Year of a payment except in accordance with Code Section 409A.
