One of Tuesday’s two experts, economist Michael Hartzmark, reviewed a report peppered with terms such as “but-for” and “consequential inflation” that made a case for calculating the damages suffered by Tesla shareholders during a 10-day period in August 2018 at anywhere from $4 billion to US$11 billion, or US$22.55 to $66.67 per Tesla share at that time.
Another expert, University of Maryland finance professor Steven Heston, reviewed an even denser report analysing the impact of Musk’s tweets on more than 2000 types of Tesla stock options, drawing largely upon a formula known as the Black-Scholes model widely used by companies to value executive compensation packages.
When pressed by a Musk lawyer about the reliability of his model, Heston acknowledged: “All models deviate from reality, which is why they are models.”
Heston, who said he was paid US$300,000 to $350,000 for his work in the case, demurred on trying to make a concrete estimate on the investor damages, saying that was a job for the jurors.
The crux of the case hinges on an August 7, 2018, tweet in which Musk declared “funding secured " to take Tesla private. Musk abruptly posted the tweet minutes before boarding his private jet after being alerted that the Financial Times was about to publish a story that Saudi Arabia’s Public Investment Fund had spent about US$2 billion buying a 5 per cent stake in Tesla to diversify its interests beyond oil, according to his testimony.
Amid widespread confusion about whether Musk’s Twitter account had been hacked or he was joking, Musk followed up a few hours later with another tweet suggesting a deal was imminent.
During roughly eight hours of sworn testimony, Musk repeatedly insisted he was looking after shareholders’ best interests and believed he had a financing commitment from the Saudi fund that was recanted after his “funding secured” tweet. Musk also testified he could have still pulled off the buyout by raising money from other investors and selling some of his stock in SpaceX, a rocket ship maker that he founded.
After consulting with Tesla’s major shareholders, Musk decided the electric automaker should remain publicly traded — a decision that has paid off for him and other investors. Tesla’s shares are now worth more than eight times what they were at the time of Musk’s buyout tweet, after adjusting for two stock splits that have occurred since then.
