Each Employment Agreement Amendment amends the relevant employment agreement to, among other things, (i) increase the cash severance multiple payable to Messrs. Hotchkiss, Vinci and Brinkman from 100% to 200% of each of base salary and the greater of (A) the target annual bonus for the fiscal year of termination and (B) the target annual bonus for the prior fiscal year, and (ii) increase the number of months used to calculate the lump sum payment representing the premium subsidy that Chart otherwise would have paid on the individual’s behalf had the individual remained employed with Chart from 12 months following the date of termination to 24 months following the date of termination, in each case, upon a specified qualifying termination of each such individual within two years following a change in control.

The Belling Employment Agreement replaces in full Mr. Belling’s previously existing letter agreement (dated as of May 30, 2023) and provides for, among other things, upon a specified qualifying termination within two years following a change in control, severance payable to Mr. Belling which consists of (i) 150% of each of his base salary and the greater of (A) the target annual bonus for the fiscal year of termination and (B) the target annual bonus for the prior fiscal year, and (ii) a lump sum payment equal to the premium subsidy that Chart otherwise would have paid on Mr. Belling’s behalf had he remained employed with Chart for 18 months following the date of termination.

With respect to each Employment Agreement, any payments and benefits payable upon a specified qualifying termination within two years following a change in control are subject to the respective individual’s (i) execution and non-revocation of a general release of claims against Chart and its affiliates and (ii) compliance with non-competition, non-solicitation, confidentiality and assignment of intellectual property provisions.

The descriptions contained herein of the Employment Agreements are qualified in their entirety by reference to the full text of the Employment Agreements, which are filed herewith as Exhibits 10.2, 10.3, 10.4 and 10.5, and are incorporated herein by reference.

Item 7.01 Regulation FD Disclosure.

On November 17, 2025, Chart issued a press release (the “Press Release”) announcing Ms. Evanko’s decision to resign. A copy of the Press Release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information furnished under Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

The matters discussed in this Current Report on Form 8-K include “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, about the plans, strategies, objectives, goals or expectations of Chart. These statements include, but are not limited to, statements about the benefits of the proposed Merger, the expected timing of the completion of the Merger, and other statements that are not historical facts. You can identify forward-looking statements by terminology such as “may,” “will,” “should,” “could,” “expects,” “believes,” “projects,” “forecasts,” “intends,” “plans,” and similar expressions. These forward-looking statements are based upon current plans, estimates, and expectations that are subject to risks, uncertainties, and assumptions, many of which are beyond the control of Chart and Baker Hughes, that could cause actual results to differ materially from those expressed in such statements. Key factors that could cause actual results to differ materially include, but are not limited to, the risks detailed in Chart’s filings with the Securities and Exchange Commission (the “SEC”), including in Chart’s most recent filings on Forms 10-K and 10-Q, factors and matters described herein and in Chart’s Definitive Proxy Statement with respect to the Merger (filed on September 8, 2025), as supplemented, and the following factors: (1) the risk that the Merger may not be completed in a timely manner or at all, which may adversely affect the businesses and the market price of the common stock of Chart; (2) the failure to obtain, or delays in obtaining, required regulatory approvals from governmental authorities, or the imposition of conditions on such approvals that may have an adverse effect on Chart or Baker Hughes or may cause the parties to abandon the Merger; (3) the occurrence of any event, change, or other circumstance that could give rise to the termination of the Merger Agreement, including in circumstances that would

require Chart or Baker Hughes to pay a termination fee; (4) the effect of the announcement and pendency of the Merger on Chart’s business relationships, operating results, and business generally, including the risk of potential difficulties in employee retention and the risk of disruption to management’s attention from ongoing business operations; and (5) the risk of litigation related to the Merger. Additional risks and uncertainties are described in the “Risk Factors” sections of Chart’s and Baker Hughes’ most recent Annual Reports on Form 10-K and in subsequent filings with the SEC. The foregoing list of factors is not exhaustive. You should not place undue reliance on any forward-looking statements, which are based only on information currently available to Chart. Chart does not undertake any obligation to update or revise any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law.
