In the following video, Motley Fool industrials analyst Blake Bos takes a look at why there was so much confusion around 3D Systems' (DDD 0.97%) earnings report. Whereas the press release stated EPS of $0.71 per share, this was prior to the split that the stock underwent Friday afternoon, and led to a lot of analyst and investor misinterpretation. The company's share count also increased by approximately 9 million shares, diluting shareholder returns. Blake tells us in the video what the actual earnings per share value is, and gives investors a much more meaningful way to calculate a company's earnings. He also tells us why diversification in 3-D printing investing is important.
