Modine Manufacturing Company, a Wisconsin corporation (the “Company” or “Modine”), and Gentherm Incorporated,
a Michigan corporation (“Gentherm”) consummated the previously announced spin-off of the Company’s Performance Technologies
business (the “Performance Technologies Business”) and the combination of the Performance Technologies Business with Gentherm
in a Reverse Morris Trust transaction (the “Closing”). Pursuant to (i) the Separation Agreement,
dated as of January 29, 2026 (the “Separation Agreement”), by and among the Company, Gentherm and Platinum SpinCo Inc.,
a Delaware corporation and, prior to the Distribution (as defined below), a wholly owned subsidiary of the Company (“SpinCo”),
and (ii) the Agreement and Plan of Merger, dated as of January 29, 2026 (the “Merger Agreement” and, together with
the Separation Agreement, the “Transaction Agreements”), by and among the Company, SpinCo, Gentherm and Platinum Gold Merger
Sub Inc., a Delaware corporation and a wholly owned subsidiary of Gentherm (“Merger Sub”): · the Company transferred, and caused certain of its subsidiaries to transfer, to SpinCo and the other members
of the SpinCo group, and SpinCo and such members accepted and assumed, the assets and liabilities of the Performance Technologies Business,
such that the Performance Technologies Business was separated from the remainder of the Company’s businesses (the “Separation”); · immediately prior to the Distribution (as defined below), SpinCo paid to the Company a cash distribution
in the amount of $155,991,275 (the “Cash Distribution”), which amount reflects a reduction from the $210,000,000 amount provided
in the Transaction Agreements as a result of the exchange ratio adjustment described below; · in addition to, and separate from, the Cash Distribution, the Separation Agreement provided for a cash
payment between SpinCo and the Company based on SpinCo's estimated net working capital, cash, indebtedness and certain expense reimbursements
as of the cut-off time specified in the Separation Agreement, which cash payment remains subject to post-closing adjustment in accordance
with the Separation Agreement; · following the Separation, the Company distributed, on a pro rata basis (the “Distribution”),
one share of SpinCo common stock, par value $0.001 per share (“SpinCo Common Stock”), for each share of Company common stock,
par value $0.625 per share (“Company Common Stock”), held by the Company’s shareholders as of the close of business
on September 28, 2026 (the “Record Date” and, such holders, the “Record Date Shareholders”); and · immediately following the Distribution, Merger Sub merged with and into SpinCo, with SpinCo surviving
the merger as a wholly owned subsidiary of Gentherm under the name “Modine Global, Incorporated” (the “Merger”
and, together with the Separation, the Cash Distribution and the Distribution, the “Transactions”), and each share of SpinCo
Common Stock issued and outstanding immediately prior to the effective time of the Merger (other than shares held by SpinCo as treasury
stock or by Gentherm or Merger Sub, which were canceled) was converted into the right to receive 0.44619 shares of common stock, without
par value, of Gentherm (“Gentherm Common Stock”), together with cash in lieu of any fractional share of Gentherm Common Stock. 1 Accordingly, each Record Date Shareholder became
entitled to receive 0.44619 shares of Gentherm Common Stock for each share of Company Common Stock held as of the close of business on
the Record Date, with cash in lieu of any fractional share. Upon completion of the Merger, Gentherm issued an aggregate of 23,735,961
shares of Gentherm Common Stock to the Record Date Shareholders. As previously disclosed, the exchange ratio was increased pursuant to
the adjustment mechanism in the Merger Agreement intended to preserve the tax-free treatment of certain aspects of the Transactions for
U.S. federal income tax purposes. As a result of the Merger, Merger Sub ceased to exist as a separate legal entity and SpinCo became a
wholly owned subsidiary of Gentherm. Immediately following the Closing, Record Date Shareholders (in their capacity as former holders
of SpinCo Common Stock) owned approximately 43.62% and Gentherm shareholders immediately prior to the Closing owned approximately 56.38%
of the combined company, in each case without taking into account any overlapping shareholder ownership. Item 1.01. Entry into a Material Definitive Agreement. On the Closing Date, in connection with the consummation
of the Transactions and in accordance with the Transaction Agreements, the Company, Gentherm and SpinCo (or, as indicated below, the applicable
parties) entered into the following additional agreements (the “Ancillary Agreements”): Tax Matters Agreement The Company, Gentherm and SpinCo entered into a Tax Matters Agreement
(the “Tax Matters Agreement”), which governs the parties’ respective rights, responsibilities and obligations with respect
to taxes of the Company, SpinCo and their respective subsidiaries (including taxes arising in the ordinary course of business and taxes,
if any, incurred as a result of any failure of the Separation, the Distribution or related transactions to qualify for their intended
tax treatment), tax benefits and attributes, the preparation and filing of tax returns, the control of tax audits and other tax proceedings,
and cooperation in respect of tax matters. The Tax Matters Agreement also imposes restrictions on the parties with respect to actions
that could cause the Separation and the Distribution to fail to qualify for their intended tax treatment and allocates responsibility
among the parties for taxes that may arise if the Transactions fail to qualify for their intended tax treatment. Employee Matters Agreement The Company, Gentherm and SpinCo entered into
an Employee Matters Agreement (the “Employee Matters Agreement”), with respect to the transfer of the employment of certain
employees of the Company and the Performance Technologies Business and other employee-related matters, including allocation among the
parties of assets, liabilities and responsibilities related to employee benefit plan and compensation arrangements and with respect to
terms of employment, benefit plan transition and coverage and other compensation and labor matters, as well as responsibility for employee
and benefit plan liabilities for certain current and former employees of the Company and the Performance Technologies Business. Transition Services Agreement The Company and SpinCo entered into a Transition
Services Agreement (the “Transition Services Agreement”), pursuant to which the Company and SpinCo will provide to each other
certain services on a transitional basis to facilitate the transition of the Performance Technologies Business to Gentherm and the operation
of the Company’s remaining businesses following the Separation. Modine will provide to SpinCo various services (which may include
HR, legal, supply chain, administrative, finance and accounting and IT) for durations anticipated to range from one to three months up
to 12 months. SpinCo will provide to Modine certain IT-related services for durations anticipated to range up to 12 months. The service
recipient may terminate any service early on 45 days’ notice and may also extend any service for up to six months in accordance
with the terms of the Transition Services Agreement. 2 Intellectual Property Matters Agreement The Company, Gentherm and SpinCo entered into an Intellectual Property
Matters Agreement (the “Intellectual Property Matters Agreement”) pursuant to which Modine and SpinCo will license to each
other certain intellectual property used in their respective businesses. Pursuant to the Intellectual Property Matters Agreement, Modine
and SpinCo each granted the other a worldwide, fully paid-up, royalty-free, irrevocable, non-exclusive license under the intellectual
property (other than trademarks, Internet domain names and social media accounts) owned by the licensor and used in the operation
of the licensee’s business to use, make, have made, sell and otherwise exploit the licensee’s products or services in the
licensee’s field of business and the improvements, enhancements and natural evolutions and extensions thereof (but excluding the
field of the licensor’s business as of the Separation). The licenses are granted without representations or warranties. The term
of the Intellectual Property Matters Agreement continues with respect to each licensed intellectual property right for so long as the
intellectual property right remains in force. Trademark Matters Agreement The Company and SpinCo entered into a Trademark
Matters Agreement (the “Trademark Matters Agreement”). In the Separation, the “Modine” trademark was transferred
to SpinCo as part of the Performance Technologies Business. Under the Trademark Matters Agreement, SpinCo granted the Company a royalty-free
license to use the “Modine” trademark to advertise, market, distribute and sell certain products and services for Modine’s
commercial, industrial, and building heating, ventilation, air conditioning, and refrigeration (“HVAC&R”) and heat transfer
products businesses. The license is exclusive for the first four years, then becomes non-exclusive, in the field of Modine’s HVAC&R
business. The license is non-exclusive with respect to Modine’s heat transfer business. In addition, SpinCo granted Modine a royalty-free,
non-exclusive transitional license to use the “Modine” trademark as otherwise used in Modine’s business as of the Separation:
(a) for up to two years after the Distribution, with three months thereafter to sell off inventory manufactured or labeled with the
trademarks; and (b) for up to two years after the Distribution to exhaust existing stock of signs, advertising, promotional and other
materials bearing the “Modine” trademark. The initial term of the license is four years for the HVAC&R business, renewing
thereafter for successive two-year periods unless Modine notifies SpinCo of non-renewal, provided that Modine is not in material breach
of the agreement. The term of the license is two years for the heat transfer business. As the Company previously announced, the Company
intends to change its name to Modexus Solutions, subject to shareholder approval of an amendment to the Company’s Articles of Incorporation. The foregoing descriptions of the Ancillary Agreements
