Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the potential merger transaction, including the expected time period to consummate the potential merger transaction, and the anticipated benefits (including synergies) of the potential merger transaction. All such forward-looking statements are based upon current plans, estimates, expectations and ambitions that are subject to risks, uncertainties and assumptions, many of which are beyond the control of Chart and Flowserve, that could cause actual results to differ materially from those expressed in such forward-looking statements. Key factors that could cause actual results to differ materially include, but are not limited to: the risk that regulatory approvals are not obtained or are obtained subject to conditions, limitations or restrictions that are not anticipated by Chart and Flowserve; the failure to receive, on a timely basis or otherwise, the required transaction-related approvals of Chart’s stockholders and Flowserve’s shareholders; potential delays in consummating the proposed merger transaction, including as a result of failure to receive any regulatory approvals (or any conditions, limitations or restrictions placed on such approvals); the ability to integrate the operations of Chart and Flowserve in a successful manner and in the expected time period; the possibility that any of the anticipated benefits and projected synergies of the proposed merger transaction will not be realized or will not be realized within the expected time period; the possibility that competing offers or acquisition proposals may be made; the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement, including in circumstances which would require Chart or Flowserve to pay a termination fee; risks that the anticipated tax treatment of the proposed merger transaction is not obtained; unforeseen or unknown liabilities; customer, stockholder, regulatory and other stakeholder approvals and support; unexpected future capital expenditures; the combined company’s ability to pay a quarterly dividend as expected; potential litigation relating to the proposed merger transaction that could be instituted against Chart, Flowserve or their respective directors; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the effect of the announcement, pendency or completion of the proposed merger transaction on the parties’ business relationships and business generally; risks that the proposed merger transaction disrupts current plans and operations of Chart or Flowserve and potential difficulties in employee retention as a result of the proposed merger transaction, as well as the risk of disruption of management and ongoing business operations during the pendency of, or following, the proposed merger transaction; uncertainties as to whether the proposed merger transaction will be consummated on the anticipated timing or at all or, if consummated, will achieve its anticipated economic benefits, including as a result of risks associated with third party contracts containing material consent, anti-assignment, transfer or other provisions that may be related to the proposed merger transaction which are not waived or otherwise satisfactorily resolved; changes in commodity prices; negative effects of this announcement, and the pendency or completion of the proposed merger transaction on the market price of Chart’s or Flowserve’s common stock and/or operating results; rating agency actions and the ability to access short- and long-term debt markets on a timely and affordable basis; various events that could disrupt operations, including severe weather, cybersecurity attacks, as well as security threats and governmental response to them, and technological changes; labor disputes; changes in labor costs and labor difficulties; the effects of industry, market, economic, political or regulatory conditions outside of Chart’s or Flowserve’s control; legislative, regulatory and economic developments targeting public companies in the industrial sector; global supply chain disruptions and the current inflationary environment; the substantial dependence of Chart’s and Flowserve’s sales on the success of the energy, chemical, power generation and general industries; economic, political and other risks associated with the international operations of Chart and Flowserve; potential adverse effects resulting from the implementation of tariffs and related retaliatory actions and changes to or uncertainties related to tariffs and trade agreements; and the risks described in Item 1A “Risk Factors” of Chart’s and Flowserve’s most recent Annual Reports on Form 10-K and in subsequent filings with the SEC.

Non-GAAP Meas ures Certain financial measures included herein, including EBITDA, Adjusted EBITDA, Adjusted EPS, Net Debt and estimates of cost and revenue synergies, among others, are not made in accordance with U.S. GAAP, and use of such terms varies from others in the same industry. Non-GAAP financial measures should not be considered as alternatives to net income (loss), net income margin or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance or cash flows as measures of liquidity. Non-GAAP financial measures have important limitations as analytical tools, and you should not consider them in isolation or as substitutes for results as reported under U.S. GAAP. Projected GAAP financial measures and reconciliations of projected non-GAAP financial measures are not provided herein because such GAAP financial measures are not available on a forward-looking basis and such reconciliations could not be derived without unreasonable effort.
