CHASE CORPORATION ANNOUNCES THIRD QUARTER RESULTS

REVENUE OF $64.9 MILLION

EARNINGS PER SHARE OF $1.26

Westwood, MA – July  5, 2017 – Chase Corporation (NYSE MKT: CCF) today reported revenue of $64.90 million for the quarter ended May 31, 2017.  This is an increase of $0.67 million, or 1%, compared to $64.24 million recognized in the same quarter of the prior fiscal year.  Net income of $11.86 million for the current quarter increased  $4.32 million, or 57%, from $7.53 million in the prior year third quarter.  Earnings per diluted share of $1.26 for the third quarter of fiscal 2017 represented an increase of $0.46, or 58%, compared to $0.80 per diluted share in fiscal 2016. Adjusted EBITDA for the current quarter increased $2.02 million, or 12%, to $18.79 million compared to $16.77 million in the third quarter of last year.

For the nine months ended May 31, 2017, revenue increased $6.93 million or 4% to $183.57 million, compared to $176.64 million recognized in the first nine months of the prior year.  Net income of $30.60 million for the first nine months of fiscal 2017 increased $8.65 million or 39% from $21.95 million in the prior year period.  Earnings per diluted share of $3.24 for the first three quarters of fiscal 2017 represented an increase of $0.90, or 38%, compared to $2.34 per diluted share in fiscal 2016. Adjusted EBITDA in the current year-to-date period increased $7.83 million, or 17%, to $53.74 million compared to $45.91 million in the first nine months of fiscal 2016.

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

“Our Industrial Materials segment produced sound results led by a favorable product mix in the quarter with revenue growing over the prior year third quarter. Our electronic and industrial coatings and pulling and detection products continued their strong organic growth in the quarter, and were further bolstered by sales from Resin Designs, acquired in the first quarter. Cable materials quarterly gains, especially sales into the communication cable markets, have the product line’s year-to-date sales favorable to the prior year. These results more than offset the low-margin revenue lost following the divestiture of our fiber optic cable component business in April. 

“Delays and non-repeating project work culminated in choppy third quarter results for our Construction Materials segment, especially as compared to the same period in the prior year. Middle East pipeline project work continued, but not at the levels seen in the recent past.  Sustained energy price weakness negatively impacted demand and was exacerbated by political instability in the region. Domestic commercial roofing, bridge work and waterproofing projects also did not recur at prior period levels, with certain projects delayed into our fourth quarter.”

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

“Following our adoption of ASU 2016-09 in the current year, and as anticipated, the Company continues to experience volatility in its effective tax rate.  For the third quarter of fiscal 2017, the Company recognized an effective tax rate of 30.7%, 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 31.1%. Further tax uncertainty exists concerning any potential future changes in the tax code regarding the repatriation of funds. As of May 31, 2017, over half of the

Company’s cash balance was held outside the United States, and changes in the code could influence the Company’s decision-making around repatriating and utilizing for domestic expansion or other uses.”

Mr. Chase also commented,

“Mergers, divestitures and acquisitions continue to be one of our stated strategies for sustainable growth. And with the sale of our fiber optic cable components business during the quarter, and the purchase of Resin Designs in September, we have effectively replaced some low-margin business with higher-margin business, adhering to our strategy and sustaining value creation for our shareholders.

“Our balance sheet remains strong, further strengthened by our $150 million revolving credit facility. We are aligned to continue pursuing our mergers and acquisitions program, while satisfying our operational cash needs.”

As of May 31, 2017, the Company’s cash on hand was $54.13 million. The outstanding balance of the Company’s $150 million revolving debt facility was $20.00 million.

The following table summarizes the Company’s financial results for the three and nine months ended May 31, 2017 and 2016.
