What happened Shares of Diebold Nixdorf Inc. (NYSE: DBD) were down 19.6% as of 11 a.m. EDT Wednesday after the ATM and POS solutions specialist reduced its 2017 revenue and earnings outlook. So what Diebold now expects full-year 2017 revenue in the range of $4.7 billion to $4.8 billion, down from previous guidance for $5 billion to $5.1 billion. On the bottom line, that should translated to a GAAP loss per share of $1.65 to $1.45 (compared to a GAAP loss per share of $0.70 to $0.40 previously), and adjusted (non-GAAP) earnings per share of $0.95 to $1.15 (down from prior guidance for adjusted EPS of $1.40 to $1.70). Diebold blamed its new forecast on its banking business, which "is increasingly made up of large, complex products with higher software content, resulting in a longer customer decision-making process and order-to-revenue conversion cycle." Consequently, these delays also hurt volumes in Diebold's service business, and will mean margin headwinds in the meantime. IMAGE SOURCE: DIEBOLD NIXDORF. Now what On a more encouraging note, CEO Andy Mattes remarked that the company is taking steps to accelerate cost reductions. Specifically, Diebold is increasing its net savings target under its multiyear business-integration and cost-savings program (dubbed DN2020) by $40 million, to $240 million. But that's little consolation to impatient investors as they watch Diebold's margins come under pressure in the near term. While Diebold's long-term story appears to remain intact, our market hates being told to effectively "hurry up and wait." So it's no surprise to see Diebold shares falling hard on today's news. 10 stocks we like better than DieboldWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
