What happened

Shares of heavy-duty truck manufacturer Oshkosh Corp (NYSE:OSK) dropped as much as 10% on Friday after giving updated guidance to investors. At 3:00 p.m. EDT, shares were still down 9.5% for the day.

So what

Management said that 2016 revenue will be $6.1 billion to $6.2 billion and earnings per share will come in at $2.85 to $3.00. For 2017 the company expects revenue to grow to $6.5 billion to $6.7 billion and earnings of $3.00 to $3.40 per share.  

The market's negative reaction comes from analyst expectations being for $3.56 per share in earnings during 2017. So, on that basis, guidance was disappointing to investors.

Now what

Keep in mind that Oshkosh is expecting significant growth on both the top and bottom lines next year, despite the fact that it isn't expecting to hit analyst estimates. The estimates from Wall Street are, after all, a guess at earnings and they can be off by a wide margin.

I would be more encouraged by future growth than disappointed at missing a guess at earnings. The discount in shares today looks like a buying opportunity for investors looking at the long-term potential of Oshkosh.
