Solstice Advanced Materials
Supplemental Pension Plan
(Effective October 30, 2025)
Article I - Purpose
Effective October 30, 2025, Solstice Advanced Materials US, Inc. adopted the Solstice Advanced Materials Supplemental Pension Plan. The purpose of the Plan is to provide eligible participants and their joint annuitants and beneficiaries under the Pension Plan with the amount of retirement income that is not provided under the Pension Plan because the participant deferred compensation under one or more nonqualified deferred compensation plans of Solstice Advanced Materials US, Inc. or a US affiliate, including the Solstice Advanced Materials Deferred Compensation Plan or, by reason of the limits imposed by Section 415 and 401(a)(17) of the Code. The Plan is also intended to cover any contractual obligation Solstice has to pay pension benefits that cannot be provided under the provisions of the Pension Plan.
The Plan applies to a participant who (i) has any portion of a Supplemental Benefit that accrues on or after October 30, 2025, or (ii) has any portion of an unpaid Supplemental Benefit that accrued prior to October 30, 2025 under the terms of a supplemental pension plan sponsored by Honeywell International Inc. and was transferred to Solstice in connection with the spinoff transaction that was effective October 30, 2025.
Except to the extent otherwise indicated, and to the extent otherwise inappropriate, the Pension Plan and the provisions thereof are hereby incorporated by reference.

Article IV - Supplemental Benefit
4.01 Payment of Supplemental Benefit
(a) Supplemental Benefits shall be payable directly to such participant, or such participant's joint annuitant or beneficiary, as applicable, from the general assets of Solstice and Solstice shall not be under any obligation to set aside any funds or other assets for the payment of the Supplemental Benefits under this Plan. Solstice may, in its sole discretion, establish funds for payment of these Supplemental Benefits. However, any and all such funds shall remain assets of Solstice and subject to the claims of creditors of the corporation. Such funds, if any, shall not be deemed to be assets of this Plan.
(b) The following rules shall be used in determining the time and form of payment for a participant’s Supplemental Benefit:
(1) Except as otherwise provided in this paragraph (b), the Actuarial Equivalent value of a participant’s Supplemental Benefit shall be paid in a single lump sum payment as of the first day of the month following 105 days after the later of the participant’s Separation from Service Date or Earliest Retirement Date. For purposes of this clause (1), the Earliest Retirement Date of a participant who participates in the Retirement Earnings Plan formula of the Pension Plan shall be his Separation from Service Date.
(2) A participant who was provided a payment election for his Supplemental Benefit prior to January 1, 2009 under the terms of the corresponding supplemental pension plan sponsored by Honeywell International Inc. and who elected an annuity as his payment form shall, prior to his benefit commencement date, be entitled to elect from among the Actuarially Equivalent annuity forms of payment available to the participant under the Pension Plan other than annuity forms with a level income option. Such payments will begin as of the first day of the month following 105 days after the later of the participant’s Separation from Service Date or Earliest Retirement Date. If a participant fails to elect an annuity payment form by the required date, his Supplemental Benefit shall be paid in a single life annuity if he is unmarried on his benefit commencement date or in a joint and 50% survivor annuity, with his opposite sex spouse on his benefit commencement date as his contingent annuitant, if he is married on his benefit commencement date.
(3) A participant who is entitled to disability pension benefits under the Pension Plan that qualify as “ancillary benefits” shall continue to receive such benefits as required by the Pension Plan as long as the participant satisfies the conditions applicable to such benefits. The Actuarial Equivalent value of such participant’s Supplemental Benefit at retirement shall be paid as of the first day of the month following 105 days after the latest date the ancillary disability pension benefits could be paid, whether or not the ancillary disability pension benefits continue to be paid to such date. The form of payment shall be determined in accordance with clause (1) or (2) as applicable.
(c) A participant’s Supplemental Benefit shall include an estimate of any service or compensation (such as during a severance period or bridge leave of absence) following the participant’s benefit commencement date that is required to be taken into account in calculating a participant’s Supplemental Benefit. In no event shall Solstice be required to recalculate or otherwise true up the Supplemental Benefit actually paid.
(d) Except as otherwise provided on Appendix A, for the purpose of determining the Actuarial Equivalent present value of a participant's accrued Supplemental Benefit, the "Applicable Mortality Table" and the "Applicable Interest Rate" shall be used, as defined below.

(1) The "Applicable Mortality Table" means the mortality table prescribed by the Secretary of the Treasury pursuant to Code Section 417(e). Such table shall be based on the prevailing commissioners' standard table (described in Code Section 807(d)(5)(A)) used to determine reserves for group annuity contracts issued on the date as of which the present value is being determined (without regard to any other subparagraph of Code Section 807(d)(5)).
(2) The "Applicable Interest Rate" means the average annual rate of interest on 30-year Treasury securities determined as of the third calendar month preceding the month during which the benefit commencement occurs.
(e) In the event that a Supplemental Benefit becomes payable and the relevant Pension Plan or agreement is terminated in accordance with its terms, then the participant shall have a right to only the Supplemental Benefit accrued to the date of termination of the relevant Pension Plan or agreement. In such event, Solstice shall remain liable for the payment of the Supplemental Benefit and payment shall be made at such times and in such manner as provided in this Section 4.01.
(f) The rights and interest of any participant, joint annuitant, or beneficiary to a Supplemental Benefit under this Plan shall be the same as any other unsecured creditor of Solstice (or any successor thereto). In the event of any bankruptcy proceeding by or against Solstice, a participant, joint annuitant or beneficiary shall be entitled to prove a claim for any unpaid portion of the benefit provided by the Plan.
(g) No person shall have a right to acceleration of any payment under the Plan. No person shall be entitled to anticipate such benefit by assignment, pledge or transfer in any form or manner prior to actual or constructive receipt of payment.
(h) Notwithstanding any provision of this Section 4.01 to the contrary, if a participant is a Specified Employee at his Separation from Service Date and payment under this Section 4.01 is required to be made or commence within the 6-month period following his Separation from Service Date, such payment shall be delayed if it is to be made in a single lump sum payment or accumulated if it is to be made in an annuity until the earlier of the first day of the seventh month following the Separation from Service Date or the first day of the month following the participant’s death, with no interest or earnings accruing on the delayed payments.
the seventh month following the Separation from Service Date or the first day of the month following the participant’s death, with no interest or earnings accruing on the delayed payments.
4.02 Death Benefits
(a) If a participant receives his Supplemental Benefit in a single lump sum payment, no Supplemental Benefit shall be paid to his surviving spouse or beneficiary following his death.
(b) If a participant elects to receive his Supplemental Benefit in an annuity that provides a survivor annuity or death benefit, the participant’s surviving spouse or beneficiary, as applicable, shall receive the applicable survivor benefit or death benefit following the participant’s death.
(c) If a participant dies before he receives his Supplemental Benefit, his surviving spouse or beneficiary shall receive the Actuarial Equivalent value of any pre-retirement surviving spouse benefits or death benefits provided by the Pension Plan (1) in the form of the annuity required by the Pension Plan if the participant elected to receive his Supplemental Benefits in an annuity, or (2) in all other cases, in the form of a single lump sum payment. Such payment will be paid or begin to be paid as of the first day of the month following 105 days after the later of the participant’s death or the date that would have been the participant’s Earliest Retirement Date.
Article V - Administration

5.01 Plan Administrator - The Plan Administrator shall be the Vice President, Total Rewards & HR Services of Solstice. Such Plan Administrator shall serve at the convenience of Solstice and shall serve without compensation. The Plan Administrator shall keep such records as necessary for the proper administration of the Plan and shall report to the Solstice Board of Directors at such time or times as the Solstice Board of Directors shall designate.
5.02 Benefit Determination - The Plan Administrator shall determine the amount and timing of any benefit paid under the Plan. The Plan Administrator shall rely on the records of Solstice in determining any participant's eligibility for and amount of benefit under the Plan. In the event that the Plan Administrator's reliance on the records of Solstice causes a benefit to be over or under paid, the Plan Administrator shall adjust future payments to be increased or decreased as required. If such future payments are insufficient to recover any overpayment to a participant, the Plan Administrator shall withhold any payments then due a participant and take any action deemed appropriate to recover the balance of the overpayment.
5.03 Benefit Claims and Appeals - The Plan Administrator shall establish a claims and appeals procedure as defined by U.S. Department of Labor regulations. Such procedures will provide that the participant has sixty (60) days upon receipt of any benefits or denial of benefits to file an appeal with the Plan Administrator. The Plan Administrator must respond within sixty (60) days of receiving the appeal, in writing, specifically identifying those Plan provisions on which the benefit denial was based and indicating what information the participant must supply in order to perfect a claim for benefits.
5.04 Nonduplication of Benefits - To avoid the duplication of benefits, the amount of any similar benefits under this Plan shall be offset and reduced by the amount of any similar benefit provided the participant under other supplemental pension plans sponsored by Solstice or its subsidiaries or affiliates for which the participant may be eligible, provided however that payment under all plans shall begin at the same time and in the same form of payment.
5.05 Compliance with Section 409A of the Code – The Plan is intended to comply with the applicable requirements of Section 409A of the Code, and will be administered in accordance with Section 409A of the Code to the extent that Section 409A of the Code applies to the Plan. Notwithstanding any provision of the Plan to the contrary, distributions from the Plan may only be made in a manner, and upon an event, permitted by Section 409A of the Code. If any payment or benefit cannot be provided or made at the time specified herein without incurring penalties under Code section 409A, then such benefit or payment will be provided in full at the earliest time thereafter when such penalties will not be imposed. To the extent that any provision of the Plan would cause a conflict with the applicable requirements of Section 409A of the Code, or would cause the administration of the Plan to fail to satisfy the applicable requirements of Section 409A of the Code, such provision shall be deemed null and void to the extent permitted by applicable law.
Article VI - Amendment and Termination
