For the year ended December 31, 2019, Cass earned $2.07 per diluted share, an increase of 2% over the $2.03 per diluted share it earned in 2018. Net income was $30.4 million, compared to $30.3 million in 2018. Revenues rose 6%, from $148.3 million in 2018 to $157.2 million in 2019.

“We are pleased to report record earnings for the fourth consecutive year. Exceeding $150 million in revenue, representing 6% growth over 2018’s record results, and again surpassing $30 million in net income while continuing to fund initiatives that support future growth are noteworthy accomplishments,” stated Eric H. Brunngraber, Cass chairman and chief executive officer.

2019 4th Quarter Recap

Transportation volumes for both invoices and dollars declined 6% as a historically robust 2018 created a difficult comparison in 2019. With manufacturing companies representing an important component of the transportation customer base, the widely reported fourth quarter 2019 contraction in this sector created year-over-year trials for the division.

Facility-related (electricity, gas, waste and telecom expense management) transaction volume was down 11%, primarily due to the loss of a high transaction volume customer, while facility expense dollar volume fell only 2%, as new, high spend customer acquisitions overcame most of the transaction shortfall.

Consolidated operating expenses increased $1,029,000 (3%) due mainly to the aforementioned investment in technology and staff required to win new business and support service growth with existing clients. Additionally, the integration costs related to the Gyve on-line generosity platform that was purchased in September are included in the fourth quarter results.

“As previously reported, the volatile business climate, competitive marketplace and the impact of a lower interest rate environment converged to create headwinds during the fourth quarter,” continued Brunngraber. “However, our sales pipelines remain strong and we continue to introduce new services that promise to accelerate earnings and overcome these challenges.”

Cash Dividend Declared

On January 28, 2020, the company’s board of directors declared a first quarter dividend of $.27 per share payable March 13, 2020 to shareholders of record March 3, 2020. Cass has continuously paid regularly scheduled cash dividends since 1934.

“Our history of uninterrupted dividend payments combined with share repurchase activity that returned nearly $23 million to shareholders during 2019 reflect the company’s commitment to rewarding shareholders in a meaningful way,” Brunngraber stated.
