“So where specifically will you be in terms of capital requirements?” asked Toni Sacconaghi, an analyst covering Tesla for Sanford C. Bernstein.

“Excuse me,” Mr. Musk responded, according to a Bloomberg transcript of the call. “Next. Boring bonehead questions are not cool. Next?”

Another analyst then tried to ask about orders for the Model 3, the mass-market Tesla vehicle seen as crucial to the company’s future.

“We’re going to go to YouTube,” Mr. Musk answered. “Sorry. These questions are so dry. They’re killing me.”

He then turned a large portion of the call over to a series of questions from Galileo Russell, who hosts a “financial talk show geared towards millennials" on YouTube, according to his profile on LinkedIn. Mr. Russell had asked on Twitter before the call if he could pose a question on behalf of individual investors, and Mr. Musk had agreed.

Over the last five years, Tesla has at times been one of the hottest stocks in the market and it has been widely owned by both individual investors and technology enthusiasts, as well as institutional investors excited about the long-term business prospects for the company.

Since the start of 2013, its shares are up more than 700 percent, dwarfing the gain of more than 80 percent for the broader Standard & Poor’s 500-stock index. But since peaking in September 2017, the shares have slumped by more than 26 percent, as concern has grown about ongoing production problems for the Model 3, and the prodigious amount of cash the company is burning through.
