Decreased Guidance During the earnings report, management decreased guidance for both FY 17 reported GAAP earnings, and adjusted earnings per share. Tennant now expects 2017 fully year reported GAAP earnings in the range of $0.05 to $0.25, down from the previously expected range of $0.85 to $1.05 per share. Further, adjusted earnings per share is now expected to be in a range of $1.50 to $1.70, well below the earlier expected range of $2.20 to $2.40. According to the report, “ The change in guidance is attributed to continued operational challenges within our business, including field service productivity, manufacturing efficiencies, and raw material inflation, which accounted for approximately $0.37 per share.” Management’s Take According to Chris Killingstad, President and CEO, “ Our third quarter results reflect slower growth in North America attributed to timing of key strategic account deals, the restructuring of our field service team, continued manufacturing inefficiencies and raw material inflation, matters we continue to address. While we faced some near-term setbacks, we are staying the course strategically and positioning Tennant to be operationally stronger than ever before. We are ahead of our acquisition plans for IPC, our core Tennant EMEA business grew by 14.6 percent in the quarter and a steady stream of new products has raised our vitality index to 47 percent. I remain confident that we are building the right platform for long-term profitable growth.” Price and Earnings Consensus Graph As you can see below, the decreased guidance, and gross margin issues have weighed heavily on the stock price and future earnings estimates.
