2012 2nd Quarter Recap

Transportation dollar volume increased more than 7%. Utility dollar volume was down 4% primarily due to generally mild weather across most of North America which decreased consumption. Overall, revenues for the quarter grew to $28.4 million, a 7% increase over the $26.6 million posted in 2011.

Net investment income decreased $.7 million, or 6%, primarily due to historically low interest rates.

Overall operating expenses were up $1.6 million, or 9%, primarily due to costs related to the integration of the company’s new environmental expense service line following its acquisition of Jacksonville, Fla.-based Waste Reduction Consultants, Inc. in January.

Six-Month 2012 Recap

For the six-month period ended June 30, 2012, the company earned $1.13 per diluted share, a 3% increase over the $1.10 per diluted share earned in the first half of 2011. Net income was $11.9 million, 4% higher than the $11.5 million earned in 2011. Revenues rose 8%, from $52.7 million in 2011 to $56.8 million in 2012.

Operating expenses were up 10%, or $3.8 million, for the reasons previously cited.

“Although sluggish economic activity and historically low interest rates present a difficult operating environment,” said Eric H. Brunngraber, Cass president and chief executive officer, “it is rewarding to see our progress on those things that we can control, such as initiatives that promise revenue growth over the long term. Our recent investment in Waste Reduction Consultants, which diversifies the Cass service portfolio, is a good example. Our strong balance sheet and ability to generate positive earnings results, despite the low interest rates, is encouraging.”

Cash Dividend Declared

On July 16, 2012, the company’s board of directors declared a third quarter dividend of $.17 per share payable September 14, 2012 to shareholders of record September 5, 2012. Cass has continuously paid regularly scheduled cash dividends since 1934.
