Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »
Tesla's revenue rose 26% year over year to $28.2 billion in the second quarter. The gains were fueled by a 23% jump in automotive sales to $20.5 billion, a 13% rise in energy generation and storage revenue to $3.1 billion, and a 50% surge in services and other revenue to $4.6 billion.
But sales weren't the issue. Soaring costs and declining margins were.
The electric vehicle (EV) maker's operating margin fell to 1.4% from 4.1% in the prior-year quarter, driven by a 47% surge in operating expenses.
All told, Tesla's adjusted net income declined 17% to $1.2 billion, or $0.33 per share. That was well below Wall Street's estimates, which had called for per-share profits of $0.54, according to Yahoo! Finance.
Worse still, Tesla's free cash flow turned negative as its capital expenditures outpaced its operating cash flow.
Investors would likely have more patience if they were confident that this spending would produce strong returns. But as Musk ramps up Tesla's capital expenditures -- to more than $25 billion in 2026 alone -- he's failing to meet previously communicated timelines for key projects such as the company's Robotaxi service and Optimus robots.
Shareholders are growing increasingly frustrated. And many investors decided to sell their shares today.
