Chart Industries Reports 2013 First Quarter Results

Cleveland, Ohio – April 25, 2013 – Chart Industries, Inc. (NASDAQ: GTLS), a leading independent global manufacturer of highly engineered equipment used in the production, storage and end-use of hydrocarbon and industrial gases, today reported results for the first quarter ended March 31, 2013. Highlights include:

Net income for the first quarter of 2013 was $15.5 million, or $0.51 per diluted share. This compares with $14.1 million, or $0.47 per diluted share, for the first quarter of 2012. First quarter 2013 earnings would have been $0.54 per diluted share excluding $1.2 million, or $0.03 per diluted share, of acquisition related retention and severance expense recorded in the quarter. First quarter 2012 earnings would have been $0.48 per share excluding $0.5 million, or $0.01 per diluted share, of acquisition related earn-out adjustments.

Net sales for the first quarter of 2013 increased 27% to $273.6 million from $216.1 million in the comparable period a year ago. Gross profit for the first quarter of 2013 was $79.5 million, or 29.0% of sales, versus $67.6 million, or 31% of sales, in the comparable quarter of 2012.

“Chart is well positioned to capitalize on growing global demand fueled by major investments across the LNG value chain,” stated Sam Thomas, Chart’s Chairman, President and Chief Executive Officer. “The major order we announced today, which will be reflected in second quarter 2013 orders and backlog, continues to validate our status as an integrated supplier of mission critical equipment for the liquefaction, distribution, storage and end use of liquefied natural gas (“LNG”).”

Mr. Thomas continued, “This latest award from PetroChina, in excess of $45 million, is similar to the order we received in the fourth quarter of 2012, it includes LNG fueling stations, self-contained LNG station modules, storage tanks and trailers for LNG service, and is indicative of the significant commitment that China has made to LNG use. In addition, the recent LNG liquefaction and long-haul trucking investments announced by several companies highlight the opportunities in the North American market due to low-cost natural gas, which are encouraging and continue to validate the LNG infrastructure build-out that is underway. We remain excited about our prospects going forward.”

Backlog at March 31, 2013 was $586.6 million, down 5% from the December 31, 2012 level of $617.4 million. Orders for the first quarter of 2013 were $243.6 million and do not include the recent PetroChina award, which will be reflected in second quarter 2013 orders and backlog. First quarter 2012 had record orders of $385.1 million including major LNG project awards in excess of $150 million for several baseload LNG projects in Australia.

Selling, general and administrative (“SG&A”) expenses for the first quarter of 2013 increased $6.6 million compared with the same period in 2012 to $47.2 million, or 17.2% of sales, which

was down as a percentage of sales from 18.8% in the prior year’s quarter. The additional costs are primarily due to the AirSep acquisition and employee-related costs as we pursue LNG-related growth opportunities.

Interest expense was $4.0 million for the first quarter of 2013, which included $2.4 million of non-cash accretion expense associated with the Company’s Convertible Notes. Therefore, cash interest was $1.6 million.

Income tax expense was $6.6 million for the first quarter of 2013 and represented an effective tax rate of 29%, the same as the prior year quarter.

Cash and short-term investments were $126.3 million at March 31, 2013, compared to $141.5 million at December 31, 2012.

SEGMENT HIGHLIGHTS

Energy & Chemical (“E&C”) segment sales increased 17.5% to $80.9 million for the first quarter of 2013 compared with $68.8 million for the same quarter in the prior year. Gross margins were lower due to project mix and some higher costs as we execute on multiple projects, including a record number of large baseload projects, and concentrate on maximizing throughput. Higher costs due to some labor inefficiencies and project scope changes negatively impacted margins about 4% in the quarter. This project was shipped during the second quarter and certain costs associated with the project scope changes may possibly be recovered. In addition, the prior year quarter margin improved about 3.5% due to completion of projects including income recognition of project reserves.

Distribution & Storage (“D&S”) segment sales increased 22.5% to $128.7 million for the first quarter of 2013 compared with $105.1 million for the same quarter in the prior year. The increase was led by substantial growth in sales of LNG equipment. D&S gross profit margin was 28.4% in the quarter compared with 28% a year ago. Gross margins improved due to product mix and higher volume.

BioMedical segment sales increased 51.8% to $64.1 million for the first quarter of 2013 compared with $42.2 million for the same quarter in the prior year. This increase is due to the AirSep acquisition that was completed during the third quarter of 2012, partially offset by continued weakness in the European market and the delay in the Medicare competitive bidding process in the U.S. BioMedical gross profit margin decreased to 34.4% in the quarter compared with 38.9% for the same period in 2012. Lower respiratory volume and product mix contributed to the decline.

OUTLOOK

Order and shipment trends are progressing as expected in 2013, with significant growth in LNG and petro-chemical opportunities, including related inquiries. We are reiterating our 2013 guidance with sales expected to be in the range of $1.2 to $1.3 billion. Full year earnings per share for 2013 are still expected to be in the range of $2.90 to $3.30 per diluted share, on approximately 30.5 million weighted average shares outstanding. Included in our 2013 earnings estimates are approximately $0.10 per diluted share for acquisition related restructuring charges associated with the AirSep acquisition. Excluding these charges, earnings are expected to be in a range of $3.00 to $3.40 per share.

Our weighted average shares projection excludes any potential future dilution impact associated with the Company’s Convertible Notes and related derivative securities, which is driven by the Company’s average stock price and would, if applicable, result in additional shares being included in weighted average shares outstanding. Upon conversion, our hedge on the Convertible Notes protects against dilution up to $84.96 per share, but until conversion occurs, the hedge is considered anti-dilutive under Generally Accepted Accounting Principles and cannot be factored when computing earnings per share.
