Chart Industries, Inc. Bank of America Industrials Conference London March 21, 2023 Exhibit 99.1

Forward-Looking Statements Certain statements made in this investor presentation are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements concerning Chart’s business plans, including statements regarding objectives, future orders, revenues, margins, earnings, performance or outlook, business or industry trends and other information that is not historical in nature. Forward-looking statements may be identified by terminology such as "may," "will," "should," "could," "expects," "anticipates," "believes," "projects," "forecasts," “indicators”, “outlook,” “guidance,” "continue," “target,” or the negative of such terms or comparable terminology. Forward-looking statements contained in this presentation or in other statements made by Chart are made based on management's expectations and beliefs concerning future events impacting Chart and are subject to uncertainties and factors relating to Chart’s operations and business environment, all of which are difficult to predict and many of which are beyond Chart’s control, that could cause Chart’s actual results to differ materially from those matters expressed or implied by forward-looking statements. Factors that could cause Chart’s actual results to differ materially from those described in the forward-looking statements include: Chart may be unable to achieve the anticipated benefits of the acquisition of Howden (the “Acquisition”) (including with respect to estimated future cost synergies); revenues following the Acquisition may be lower than expected; operating costs, customer losses, and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers and suppliers) resulting from the Acquisition may be greater than expected; our ability to successfully close on our intention to divest two product lines and achieve the anticipated proceeds from those divestitures; slower than anticipated growth and market acceptance of new clean energy product offerings; inability to achieve expected pricing increases or continued supply chain challenges including volatility in raw materials and supply; risks relating to the conflict between Russia and Ukraine, including potential energy shortages in Europe and elsewhere and the other factors discussed in Item 1A (Risk Factors) in Chart’s most recent Annual Report on Form 10-K filed with the SEC, which should be reviewed carefully. Chart undertakes no obligation to update or revise any forward-looking statement. Use of Non-GAAP Financial Information This presentation contains non-GAAP financial information, including estimated future cost synergies, commercial synergies, free cash flow, adjusted EBITDA and adjusted diluted EPS attributable to Chart as a result of the Acquisition. Chart believes these forward-looking non-GAAP measures are of interest to investors and facilitate useful illustrations of Chart’s estimated future financial results, and this information is used by Chart in evaluating internal performance. With respect to Chart’s estimated future financial results, Chart is not able to provide a reconciliation of each non-GAAP financial measure presented because certain items may have not yet occurred or are out of Chart’s control and/or cannot be reasonably predicted, and therefore such reconciliations are not available without unreasonable efforts.

Chart consolidated FY2023 is line with previously communicated 12-month pro forma illustrative EBITDA of ~$1B at the mid-point of the range EBITDA and Adjusted EBITDA are not measures of financial performance under U.S. GAAP and should not be considered as an alternative to net income in accordance with U.S. GAAP. Management believes that EBITDA and Adjusted EBITDA facilitate useful period-to-period comparisons of financial results and the information is used by us in evaluating our internal performance. “Free cash flow” and “adjusted free cash flow” are not measures of financial performance under U.S. GAAP and should not be considered as an alternative to net cash provided by (used in) operating activities in accordance with U.S. GAAP.  The Company believes this figure is of interest to investors and facilities useful period-to-period comparisons of the Company’s operating results.

Demand is Strong and Deleveraging a Focus Strong demand reflected in both Chart and Howden orders 2022 full year RECORD orders in both Howden and Chart Howden fourth quarter 2022 was the highest order quarter in history First quarter 2023 quarter-to-date (as of March 15, 2023) GTLS standalone orders of $520 million First quarter 2023 quarter-to-date orders for Howden ahead of original forecast Backlog Both Chart and Howden entered 2023 with stronger than typical backlog for conversion to revenue in that year Quality customers with strong banks and funding Neither company has direct or indirect links to or accounts with Silicon Valley Bank, First Republic, Silvergate Neither company has current customers paying from accounts at any of these banks and no exposure to receivables outstanding collections from customers paying from these banks Deleveraging focus Reiterating our year-end 2024 anticipated net leverage ratio of 2.5X to 2.9X, before divestiture proceeds Reiterating our financial policy of no material acquisitions and no share repurchases until we are in our target net leverage range
