He also forgot to point out that the media kept hitting hard on the "Tesla would be out of business if weren't for US subsidies, and loans" story. In fact, he mentions timing 8 days after conference call. Well, I'm not chronologically challenged, and I remember that shortly before Elon announced he was going to raise funds with secondary offering, Palin went crazy on social media about Tesla and Obama government support.
If you ask me, the finance round had more to do with Elon and Tesla being tired of always having to correctly point out that the loan wasn't a government bailout like GM and other car dealers got, but a DOE loan initiated during Bush administration.
During secondary offering, Elon raised funds to expand infrastructure, got rid of some of these ignorant complaints in the media, purchased more shares himself to insure he kept primary control of Tesla, and freed himself from government oversight on how to grow and manage his business. If you ask me, paying off the DOE loan early was among the first of a long series of positive and well timed media strikes. From May on, we had some kind of positive announcement in the Media about every 3 weeks which is what I believe is responsible for the large Market Cap it has today.
