CHASE CORPORATION ANNOUNCES SECOND QUARTER RESULTS

REVENUE OF $57.3 MILLION

EARNINGS PER SHARE OF $0.89

Westwood, MA – April 5, 2017 – Chase Corporation(NYSE MKT: CCF) today reported revenue of $57.31 million for the quarter ended February 28, 2017.  This is an increase of $2.38 million, or 4%, compared to $54.92 million recognized in the same quarter of the prior fiscal year.  Net income of $8.38 million for the current quarter increased  $1.41 million, or 20%, from $6.97 million in the prior year second quarter.  Earnings per diluted share of $0.89 for the second quarter of fiscal 2017 represented an increase of $0.15, or 20%, compared to $0.74 per diluted share in fiscal 2016. Adjusted EBITDA for the current quarter increased $2.01 million, or 14%, to $16.54 million compared to $14.53 million in the second quarter of last year.

For the six months ended February 28, 2017, revenue increased $6.26 million or 6% to $118.67 million, compared to $112.40 million recognized in the first six months of the prior year.  Net income of $18.75 million for the first six months of fiscal 2017 increased $4.33 million or 30% from $14.42 million in the prior year period.  Earnings per diluted share of $1.99 for the first half of fiscal 2017 represented an increase of $0.45, or 29%, compared to $1.54 per diluted share in fiscal 2016. Adjusted EBITDA in the current year-to-date period increased $5.81 million, or 20%, to $34.96 million compared to $29.14 million in the first six months of fiscal 2016.

Adam P. Chase, President and Chief Executive Officer, commented,

“Our Industrial Materials segment performed well in the quarter, with sales increasing over the prior year second quarter. Last quarter’s Resin Designs acquisition delivered solid results, which added to organic growth contributions from our electronic and industrial coatings and pulling and detection products. 

“With Middle East pipeline project delays and general weakness in that region continuing, our Construction Materials segment completed its normally seasonally slower second quarter behind the prior year. However, our coating and lining systems sales were a bright spot for the segment during the quarter.”

Kenneth J. Feroldi, Treasurer and Chief Financial Officer, added,

“After adopting ASU No. 2016-09 at the start of the fiscal year, the Company has continued to experience the anticipated volatility in its effective tax rate. For the second quarter of fiscal 2017, the Company recognized an effective tax rate of 33.7%, with the rate affected by a discrete tax benefit related to stock-based compensation.  Our effective tax rate for the year-to-date period was 31.3%.

“With less volatility in foreign currency exchange rates in the period, our recognized net transactional gains and losses were not significant for the current quarter, especially as compared to net gains recognized in the quarterly and year-to-date periods in the prior year.”

Mr. Chase also commented,

“We continue to make progress on our mergers, acquisitions and divestitures program. The integration of Resin Designs’ operations onto Chase’s ERP system continued during the quarter, and the post-acquisition financial results provided us a comparative benefit over the prior year. As previously announced, we sold our former Corporate headquarters in Bridgewater, MA in December, recognizing a gain on the sale.  In April, following the second quarter, we completed the sale of our fiber optic cable components business, for which a gain will be recognized in the third quarter.

“During the current quarter, Chase began utilizing its new $150 million credit facility. The size and flexibility of the new credit facility provides us ample capital to pursue our mergers and acquisitions program. Given the all-revolver nature of the new credit facility, we have begun utilizing excess cash to pay down the principal balance of our debt, and may draw on the facility in the future to finance M&A activity as well as other operational needs.”

As of February 28, 2017, the Company’s cash on hand was $40.81 million. The outstanding balance of the Company’s new $150 million revolving debt facility was $25.00 million.

The following table summarizes the Company’s financial results for the three and six months ended February 28, 2017 and February 29, 2016.
