Henry Wallace, Diebold's executive chairman, called the company's 2012 results, along with its current 2013 outlook, "disappointing" and said that things need to improve.
Wallace said the company still expects to post a 2013 profit that is "flat to down modestly" from 2012 on relatively flat revenue. The first-quarter's results are also expected to be "weak" and come in "well below" year-ago levels, he said.
Analysts expect earnings of $2 per share on revenue of $3.03 billion.
Diebold shares fell 19 cents to $29.90 in morning trading Tuesday. They are near the low end of their 52-week range of $27.66 to $42.93.
