January 2023 Investor Update January 6, 2023 NYSE: GTLS 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: the conditions to the completion of the acquisition of Howden (the “Acquisition”) may not be satisfied or the regulatory approvals required for the Acquisition may not be obtained on the terms expected, on the anticipated schedule, or at all; sufficient long-term financing may not be available on favorable terms, or at all; closing of the Acquisition may not occur or may be delayed; Chart may be unable to achieve the anticipated benefits of the Acquisition (including with respect to 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; 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 outbreak and continued uncertainty associated with the coronavirus (COVID-19) and 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 historical adjusted EBITDA and Free Cash Flow Conversion, as well as estimated future cost synergies, revenue synergies, free cash flow, adjusted EBITDA and adjusted EBITDA margins attributable to Chart as a result of the Acquisition. Please see the reconciliation table in the appendix for the adjusted EBITDA and Free Cash Flow Conversion reconciliations. Chart believes these forward-looking non-GAAP measures are of interest to investors and facilitate useful illustrations of Chart’s estimated future financial results if the Acquisition is completed, and this information is used by Chart in evaluating internal performance. With respect to Chart’s estimated future financial results if the Acquisition is completed, 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.

They are also a mission critical part of hydrogen liquefaction, helium liquefaction, CCUS, and water treatment, etc. Example: Piston compressors were traditional solution for hydrocrackers (a traditional refining process). They are now deployed in green hydrogen production to compress H2 produced by electrolysis. Diaphragm compressors had traditional applications in the chemical industry and are now the best solution when high pressures are needed in a hydrogen refuelling station.

Howden’s Digital Offering Overview Uptime Ventsim™ Design Simulates the ventilation environment Accurately model, design, evaluation, and optimize underground mine ventilation systems Sold as a license Ventsim technology is used globally in over 80% of large operating mines along with majority of ventilation consultants and mining universities Licensed to over 2,000 sites around the world Over 70 types of data incl. airflow, pressure, heat, gases, Radon, fire, financial, and DPM Digital platform for gathering, interpreting and analyzing data from Howden and other OEMs rotating equipment Anomaly detection and view of asset health AI powered machine learnings & analytics Digital twin Securely manage assets in the cloud Predictive maintenance Direct link to Howden experts Asset documentation AR HoloLens capability

Howden’s Uptime Technology in Action Situation Howden’s Uptime Solution Identifies wear or developing failures Advises on efficiency improvements and maintenance actions Supported by a Digital Twin Models root cause scenarios Visualization tools to plot vibration patterns and identify changes Customer has several reciprocating compressors installed at plant Wet process gas can lead to catastrophic failure by increasing the pressure up to five times its normal value. As a result, the rod load increases, leading to parts failure/ destruction, and increased power consumption Result: After installing Howden Uptime, the technology detected and increase in vibration on the compressor at both the crank end and head end. Audio playback confirmed the typical squeaking noise that is heard when wet gas is passing through a valve. It was concluded that a technician should review the gas condition and separator functioning, as well as cylinder lubrication

Howden’s Ventsim™ Case Study Situation Howden’s Ventsim™ Solution Customer was trying to maximize safety while minimize carbon emissions and energy usage One of the largest operational costs for an underground mine is the ventilation system. In the case of this mine, there was a total of approximately 18,000 HP of fans installed, 50% being underground auxiliary fans and 50% main surface fans Unique control strategy specific to customer’s requirement Analyze mine ventilation with a graphically-rich 3D simulation show airflow, velocity, pressure, and more, including costs. The speed of the main fans were governed by a “speed optimizer” while auxiliary fans were equipped with on/off starter. Different level of controls were used for scheduling and ventilation on demand (VOD) that tracked data collected by vehicles and personal tags Result: The project resulted is C$ savings of $2.9mn a year between the main and auxiliary fans. Further, the mine has more flexibility to draw more air when required improving response time to any adverse conditions
