The letter arrives at a time of declining share values and increasing controversy, much of which is centered on Musk's leadership. Last week, the automaker held its first quarterly earnings call of the year, revealing dwindling profits and income-generating solutions which struggled to win over concerned investors, who have grown increasingly anxious over the company's price-cutting strategy. During the call, the CEO noted further discounts were likely since the company was now prioritizing demand over profit margins. Musk posited that self-driving subscriptions would recoup any losses from lower automotive revenue and promised that the brand would have software capable of autonomous driving later this year. These assurances failed to prevent share prices from trading nearly 10% down the day after the call. Since the start of the month, Tesla stock has fallen 22% in total.
