Tesla’s vehicle sales recovered in the second quarter, but negative free cash flow, declining margins and increasing AI spending present new threats for TSLA investors.Tesla (TSLA) finally gave investors the car comeback they’ve been waiting for. But the profits and cash flow never came.Revenue jumped 26% to $28.24 billion in the second quarter from a year earlier, with automotive revenue rising 23% to $20.52 billion. Tesla delivered 480,126 vehicles, up 25%, following two consecutive quarters of improving sales.First, those advances look optimistic for a corporation whose main electric-vehicle industry has been beset by softer demand, rising competition, and pricing pressure.The rest of Tesla’s report offers a tougher narrative.Excluding one-time charges, earnings fell to 33 cents a share from 53 cents a year ago. Analysts polled by FactSet had forecast 53 cents per share, MarketWatch noted. Operating income fell 57% to $398 million, Tesla’s operating margin shrinking to 1.4% from 4.1% a year ago. Shares slumped 4.1% in after-hours trade after the announcement.Most significantly, Tesla generated negative free cash flow of $1.09 billion as quarterly capital expenditures surged 142% to $5.79 billion.This leaves Tesla shareholders with a big problem: The company’s auto industry is recovering just as its artificial intelligence, Robotaxi, and robotics ambitions are starting to burn much more cash.“This is a massive capex year, but I’m confident all the things we’re investing in will yield incredible returns,” CEO Elon Musk told investors, as The Wall Street Journal reported.Tesla’s vehicle rebound did not protect its marginsTesla’s record second-quarter deliveries prove there is demand for its automobiles.Deliveries of Model 3 and Model Y jumped 25% to 467,762. Global vehicle inventories declined to 15 days of supply from 24 days a year before. Automotive sales revenue, excluding leasing and regulatory credits, jumped 27% to $20.01 billion.The company’s profitability didn’t grow at the same pace.Related: Tesla now has a serious software rivalAutomotive gross margin decreased to 16.9% from 17.2% a year ago. Average vehicle costs were basically unchanged, as the negative sales mix and currency impact outweighed warranty advantages and decreased tariff expenses, Tesla said.Another headwind was regulatory credit revenue. Credit sales down 67% to $146 million from $439 million. Those credits cost little, so their loss can hit Tesla’s earnings disproportionately hard.Key numbers for Tesla investors$28.24 billion: Second-quarter revenue480,126: Vehicles delivered33 cents: Adjusted earnings per share1.4%: Operating marginNegative $1.09 billion: Free cash flow$5.79 billion: Capital expenditures$43.52 billion: Cash and short-term investmentsTesla’s energy sector also had mixed results. Storage installations rose 41% to 13.5 gigawatt-hours, while the segment’s gross margin decreased to 20.4% from 30.3% as revenue gained 13% to $3.14 billion.Tesla is asking investors to fund a different companyTesla’s cash-flow problem is a change in spending deliberately, not plummeting car revenue.Research and development costs rose 49% to $2.37 billion, largely due to higher spending on AI and other new programs. Tesla forecasts more than $25 billion in capital expenditures in 2026 as it expands data centers, computer infrastructure, production lines, Robotaxis, and the Optimus humanoid robot.More Tesla:Tesla merger with SpaceX won’t save investors, top analyst saysTesla stock gets a surprising SpaceX resetTesla’s $1.4 trillion valuation rests on what happens next in one cityThat spending is altering the investing thesis for Tesla.The business is increasingly trying to get investors to value it not as a car producer, but as an emerging AI, robotics, and autonomous-transportation platform. But its core automotive business still accounts for a large share of the profit that supports such endeavors.The Full Self-Driving subscriptions are a positive indication for Tesla. Active subscriptions rose by 56% to 1.48 million, possibly giving a substantial stream of recurring software revenue. The company also announced it has begun production of its Cybercab and grown its Robotaxi business.The question remains whether the company can obtain real returns.Tesla indicated capital spending could continue to increase over the next two to three years, the Associated Press reported. Its regulatory filing also cautioned that periods of increased investment may necessitate financing beyond cash from operations.

The stock takeaway from Tesla’s earnings missTesla’s quarter does not indicate that its automobile business is in free fall.Revenue and deliveries rebounded, inventory fell, and the corporation had $43.52 billion in cash and short-term investments. Those considerations give Tesla plenty of financial capacity to keep investing.The problem is that the increased sales are not creating the operating leverage that investors had hoped for.Lower regulatory-credit income, lower margins, and a quick increase in research and capital spending meant Tesla had negative free cash flow, even in a quarter of record deliveries.The positive argument is that Robotaxis, AI software, and Optimus will eventually create businesses with better margins and more recurring revenue than car-making.The pessimistic thesis is that Tesla invests tens of billions of dollars in such items before they generate enough cash flow to justify the investment.Tesla has proven that it can bring automobile consumers back. Its next challenge is more difficult: to prove its revived automotive industry can pay Musk’s costly technology goals without gradually eroding the financial results that underpin the stock.Related: Bank of America revamps Tesla forecast before earnings
