Bridgewater, MA — October 23, 2014 — Chase Corporation (NYSE MKT: CCF) today reported revenues of $61.0 million for the quarter ended August 31, 2014.  This represents an increase of $2.5 million or 4.2% compared to $58.6 million in the same quarter of last fiscal year.  Net income attributable to Chase Corporation of $7.0 million in the current quarter increased $1.1 million or 19.0% from $5.9 million in the prior year period.  Earnings per diluted share of $0.75 in the fourth quarter of fiscal 2014 represented an increase of $0.11 compared to $0.64 per share in fiscal 2013.

For the fiscal year ended August 31, 2014, revenues increased $7.9 million or 3.7% to $224.0 million, compared to $216.1 million in the prior year.  Net income attributable to Chase Corporation increased $9.4 million or 54.7 % to $26.6 million or $2.86 per share in the current fiscal year from $17.2 million or $1.87 per share in fiscal 2013.

The Company also announced a cash dividend of $0.60 per share to shareholders of record on November 3, 2014 and payable on December 4, 2014.

Peter R. Chase, Chairman and Chief Executive Officer, commented,

“Fiscal Year 2014 was very successful despite many challenges that our leadership team overcame to achieve the results.  Our balance sheet is very strong with ample working capital for expected needs.

“We are increasing the annual dividend this year to a total of $0.60 per share.  We have been consistent in paying an annual dividend, recognizing its importance to many shareholders, and expect to maintain this practice.  In addition to our regular dividend on operating results of $0.50 per share is an additional distribution of $0.10 per share related to the sale of a non-strategic business earlier in the year.

Adam P. Chase, President and Chief Operating Officer, added,

“We had a strong finish to the fiscal year.  Solid performances from our European operations continued in the fourth quarter led by Middle East project demand for pipeline coatings and European automotive application demand for electronic coatings.

“Our strategic diversification continues to serve us well with several product lines in both segments exceeding expectations, offsetting shortfalls from others, and leading to growth for the quarter and fiscal year.  Several strategic operations initiatives were successfully completed in fiscal 2014.  Following the sale of our Insulfab® product line and associated assets in the first quarter, we consolidated other business from our former Taylorsville, NC plant into the nearby Lenoir facility.  The Enterprise Resource Planning (ERP) system implementation is on track for full company-wide deployment by the end of this calendar year.  We are grateful for the efforts our associates have demonstrated over the past two years to make this important project a success and for their dedication in driving continuous improvement.”

Peter R. Chase also commented,

“On a personal note, I am completing my 21st year as Chief Executive Officer of Chase Corporation.  I have been blessed with many dedicated, hard-working associates throughout the years and am grateful for their significant contributions toward the growth of the company.  During the past few years we have worked to upgrade our

management talent and succession planning at all levels which has enabled us to improve results.  Organizational development has included a number of new senior management positions.  In addition, Adam Chase, President and Chief Operating Officer, has steadily assumed more of the day-to-day management responsibility.  Effective with our annual shareholders meeting scheduled for February 3, 2015, and subject to final board approval at that time, Adam will be named Chief Executive Officer and I will move to Executive Chairman.  Adam and I have worked closely together for a number of years and will continue to do so for the foreseeable future.”

The following table summarizes the Company’s financial results for the three months and years ended August 31, 2014 and 2013.

As of August 31, 2014, the Company’s net working capital was approximately $90 million, including cash on hand of $53 million. Cash grew by $23.2 million over the fiscal year from a combination of both normal operations and $9.2 million from the sale of a non-strategic business.  The outstanding balance of the Company’s term debt is $58.8 million.  The Company’s $15.0 million line of credit is fully available.
