Chart Industries Reports 2012 Second Quarter Results

Cleveland, Ohio—August 2, 2012—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 second quarter ended June 30, 2012. Highlights include:

Net income for the second quarter of 2012 was $17.9 million, or $0.59 per diluted share. This compares with $10.6 million, or $0.35 per diluted share, for the second quarter of 2011. Second quarter 2012 earnings would have been $0.57 per diluted share excluding $1.1 million, or $0.02 per diluted share, of net favorable earn-out adjustments related to prior acquisitions partially offset by impairment charges and the write-off of deferred financing fees associated with the credit facility amendment which closed during the quarter. Second quarter 2011 earnings would have been $0.41 per diluted share excluding $2.8 million, or $0.06 per diluted share, of acquisition-related restructuring costs.

The second quarter of 2012 also included $1.8 million in foreign currency loss, or $0.04 per diluted share, largely due to a weak euro which impacted European operations, particularly in our BioMedical segment.

Net sales for the second quarter of 2012 increased 20% to a record $239.9 million from $200.7 million in the comparable period a year ago. Gross profit for the second quarter of 2012 was $74.1 million, or 30.9% of sales, versus $62.3 million, or 31.1% of sales, in the comparable quarter of 2011.

“We are very excited about the pending AirSep acquisition, which strengthens our BioMedical Group’s oxygen concentrator business and our gas processing business overall, providing a growth platform for on-site air separation gas generation,” stated Sam Thomas, Chart’s Chairman, President and Chief Executive Officer. “The acquisition also represents an attractive and stable complement to our large and rapidly growing energy business.”

Mr. Thomas continued, “In addition, during the quarter we announced our fourth major plant expansion project in response to continued strong LNG demand. This latest expansion will address large tank manufacturing capacity at our New Prague, Minnesota facility. We are committed to meeting our customers’ growth needs, as order rates for LNG tanks, combined with ongoing demand for large industrial tanks, have out-stripped current capacity.”

Backlog at June 30, 2012 was $648.1 million, down 1.7% from the record March 31, 2012 backlog of $659.3 million. Orders for the second quarter of 2012 were $228.0 million compared with record first quarter 2012 orders of $385.1 million. The first quarter of 2012 included two large Australian LNG-related orders for approximately $155 million. Excluding those two large awards, second quarter 2012 orders were down 1% sequentially compared to first quarter 2012 on weak European demand and softer industrial Packaged Gas demand, mostly offset by strong LNG infrastructure orders.

Selling, general and administrative (“SG&A”) expenses for the second quarter of 2012 decreased $1.6 million compared with the same period in 2011 to $34.7 million, or 14.5% of sales, which was down as a percentage of sales from 18.1% in the prior year quarter. The second quarter 2012 SG&A included $4.4 million in favorable net earn-out adjustments associated with prior acquisitions. Earn-out targets for one acquisition are not expected to be met and the liability was reversed. This was partially offset by higher stock compensation and employee-related costs as we continue to expand our resources to capture LNG-related growth opportunities.

Interest expense was $3.7 million for the second quarter of 2012, which included $2.3 million of non-cash accretion expense associated with the Company’s Convertible Notes. Therefore, cash interest was $1.4 million.

Income tax expense was $8.9 million for the second quarter of 2012 and represented an effective tax rate of 33.0%, which was the same as the tax rate in the prior year quarter. The increase from the first quarter 2012 tax rate is largely due to the increased mix of domestic earnings.

Cash and short-term investments were $254.7 million at June 30, 2012, approximately $12 million higher than balances at March 31, 2012. The AirSep acquisition is expected to close during the third quarter and will largely be funded from available U.S. cash.

SEGMENT HIGHLIGHTS

Energy & Chemical (“E&C”) segment sales increased 57% to $77.1 million for the second quarter of 2012 compared with $49.1 million for the same quarter in the prior year. Gross margins improved to 30.2% in the 2012 quarter compared with 29.0% in the same quarter of 2011. The improvement is primarily due to higher production throughput and pricing partially offset by higher training costs as we continue to ramp up production on large LNG projects.

Distribution & Storage (“D&S”) segment sales improved 12% to $113.4 million for the second quarter of 2012 compared with $101.7 million for the same quarter in the prior year. The increase in sales was largely due to improved volume, particularly LNG applications including mobile equipment and bulk storage tanks. The acquisition of GOFA in August 2011 also contributed to the improvement. D&S gross profit margin was 27.2% in the quarter compared with 28.2% a year ago. The year over year decline was primarily attributed to changes in product and geographic mix, rapid growth in the D&S China operation resulting in higher production costs in the quarter, in addition to facility ramp-up costs as a result of capacity expansion projects underway in both the U.S. and China to address LNG growth opportunities.

BioMedical segment sales were essentially the same at $49.4 million for the second quarter of 2012 compared with $49.9 million for the same quarter in the prior year. Gross margins improved to 40.4% in the 2012 quarter compared with 38.8% in the same quarter of 2011. Restructuring costs due to the shutdown of the Plainfield, Indiana facility negatively impacted margins by about 3% in the prior year quarter. Excluding restructuring costs, margins were somewhat lower in the second quarter of 2012 due to a weaker euro.

OUTLOOK

We continue to experience strong order intake and prospects for LNG-related opportunities, natural gas processing, and petro-chemical applications. While softening of activity in industrial gas and BioMedical respiratory, particularly in Europe, has tempered our expectations somewhat for the near term, we remain confident in our long-term prospects. We are reiterating our 2012 sales guidance range of $950 million to $1 billion, but tightening the range of our previous earnings guidance. Full year earnings per share for 2012 are now expected to be in the range of $2.60 to $2.80 per diluted share, on approximately 31 million weighted average shares outstanding. Our sales and earnings per share outlook does not reflect the pending acquisition of AirSep, but will be updated upon or after the close of this transaction.
