2019 3rd Quarter Recap

Third quarter revenue and net income both increased a healthy 8%. Factors continuing to influence performance were an expanding customer base and the development and deployment of new revenue-generating services. The positive bottom-line results were achieved despite significant on-going investment in technology and infrastructure to support global expansion and future service growth.

Transportation invoice volume declined 3% as a historically robust 2018 created a challenging comparison in 2019. Additionally, dollar volume decreased 2% as a result of a softening carrier market.

Facility-related (electricity, gas, waste and telecom expense management) dollar volume was up a strong 12% due to significantly increased “spend” by several major clients plus contributions from new customers. Facility expense transactions volume increased slightly as the mix of customers, particularly in telecom expense management, changed from a relatively high transaction/low dollar to a relatively low transaction/high dollar average customer. Actual customer counts increased for the quarter.

Consolidated operating expenses increased $2.0 million (7%) due mainly to on-going strategic investment in the technology and staff required to win new business and support service growth with existing clients.

“It is gratifying to see internal investments that we have made in recent years contribute to another record setting earnings performance in the third quarter,” stated Eric H. Brunngraber, Cass chairman and chief executive officer. “While we are pleased with the third quarter results, we are closely monitoring today’s volatile business climate, increasingly competitive marketplace, and the impact of a lower interest rate environment on our net interest margin. We are confident that our strong financial position and on-going commitment to investing in the people and technology required to execute our long-term plan for growth, will serve us well.”

2019 Earnings Up 6% at Nine-Month Mark

For the nine-month period ended September 30, 2019, the company earned $1.64 per diluted share, an increase of 6% from the $1.55 per diluted share it earned in the same period in 2018. Net income was $24.0 million, compared to $23.2 million in 2018. Revenues rose 8%, from $110.0 million in 2018 to $118.3 million in 2019.

Consolidated operating expenses were up 8%, or $6.8 million, due to increased business and the strategic investments previously cited.

4% Increase in Cash Dividend

On October 22, 2019, the company’s board of directors declared a fourth quarter dividend of $.27 per share payable December 13, 2019 to shareholders of record December 3, 2019. The new quarterly dividend is one cent or 4% higher than the previous pay-out of $.26 per share. Cass has continuously paid regularly scheduled cash dividends since 1934.

Additionally, after repurchasing more than 300,000 shares of common stock in the past 12 months, the board voted to restore the capacity of the company’s stock repurchase program to 500,000 shares.

“Our history of dividend payments combined with the return of nearly $16 million to shareholders through share repurchase activity over the past 12 months reflects our solid operating performance, strong capital base and the board’s continued optimism about the company’s long-term prospects,” said Brunngraber.
