Tesla is working on many expensive projects, and its primary source of funding will have to be equity issuance. Let's take a look at Tesla's share count - will this drag down the price of the stock?The share count was over 148 million by the end of Q2 - but it doesn't stop there. The company's quarterly share count for EPS was 140 million, but that excluded almost 15 million shares because they were anti-dilutive. Also, if the SolarCity (NASDAQ:SCTY) deal goes through, that will add more than 10 million more shares to the count. If there is another equity raise before the Model 3 launch, it is quite possible that Tesla's outstanding share count could be 175 million by the end of 2017.The good news is that this is, so far, having little negative effect on the price of the stock. The Market is still optimistic about Tesla.
