We have a 25% interest in Hydrogen Technology & Energy Corporation (“HTEC”) which totaled $72.0 and $68.9 at June 30, 2025 and December 31, 2024, respectively. Our investment in HTEC is accounted for under the equity method of accounting. HTEC designs, builds, and operates hydrogen fuel supply solutions to support the deployment of hydrogen fuel cell electric vehicles.

On April 30, 2025, (the “Effective Date”), we entered into a Co-Investment Agreement (the “Co-Investment Agreement”) with certain affiliates of MSD Partners, L.P., (collectively, “BDT&MSD”), in connection with BDT&MSD’s purchase (the “Share Purchase”) of all of the shares of common stock of HTEC, owned by (and from) ISQ HTEC HoldCo Limited, (“ISQ”), pursuant to a Share Purchase Agreement by and among BDT&MSD, ISQ, Chart and HTEC (the “SPA”). ISQ no longer owns any equity interests in HTEC.

•In the following circumstances, BDT&MSD shall have the right to sell to Chart all (and not less than all) of the shares of HTEC common stock acquired by BDT&MSD from ISQ on the Effective Date and which are still held by BDT&MSD at such time (the “Put Option”):

iii.the date upon which Chart, during the period from the Effective Date through the third anniversary of the Effective Date, has made certain distributions to its shareholders (including cash or other dividends, or via a spin-off transaction), in excess of $900.0,

•In the event that BDT&MSD exercises its Put Option, we shall pay to BDT&MSD an amount in cash equal to $323.0 or $51.20 per share (“Base Price”) in exchange for each relevant share of HTEC (the “BDT&MSD Put Option Consideration”); provided, however, that, upon the occurrence of the first triggering event that occurs on or after the third anniversary of the Effective Date (or if the first triggering event occurs prior thereto, but the closing of the Put Option has not been consummated prior to the third anniversary), the Base Price shall increase at the annualized rate of 11.25% until the closing of the Put Option.

•Conversely, at any time after the third anniversary of the Effective Date, Chart shall have the right to purchase from BDT&MSD up to an aggregate of 85% of the shares of HTEC common stock acquired by BDT&MSD from ISQ on the Effective Date and which are still held by BDT&MSD at such time (the “Call Option”). In the event that Chart exercises the Call Option, Chart shall pay to BDT&MSD an amount in cash in exchange for such common stock such that BDT&MSD shall realize the greater of (i) an internal rate of return of 12.75% and (ii) a multiple on BDT&MSD’s invested capital of 1.80x, in each case with respect to each share of HTEC common stock which is subject to the Call Option.

•The Co-Investment Agreement shall terminate automatically upon the consummation of an initial public offering by HTEC of its common stock.

In connection with the sale by ISQ of all of its equity interests in HTEC to BDT&MSD as further described above, the following agreements, each of which has been previously disclosed by us in our Annual Report on Form 10-K dated December 31, 2024, were terminated by all of the parties thereto as of the Effective Date: (i) that certain Co-Investment Agreement, dated as of September 7, 2021, by and between Chart and ISQ, and (ii) that certain Tri-Party Agreement, dated as of October 2, 2024, by and among Chart, HTEC, ISQ, Colin Armstrong and Cenco Innovations Ltd.

We record the Put and Call Options (together “the Options”) at fair value and record any change in fair value through earnings at each reporting period. The fair value of the put option and call option under the Co-Investment Agreement, dated as of April 30, 2025 was not material on June 30, 2025.
