Tesla's Q3 Profit Falls 43% as AI Spending and Lower Credits Bite

Tesla's third-quarter revenue held near $28 billion, but the cost of building its autonomy, robotics and manufacturing ambitions pushed reported profit sharply lower. Net income attributable to common shareholders fell 43% from a year earlier to $787 million, while the operating margin narrowed to 2.6% from 5.8%.

Automotive revenue declined 3% to $20.56 billion as lower average selling prices and a 2% drop in deliveries offset growth elsewhere. Tesla delivered 486,532 vehicles, about 6,400 more than in the second quarter but 10,567 fewer than a year earlier. Regulatory-credit revenue dropped as more rival automakers built their own electric-vehicle fleets.

Energy generation and storage revenue fell 16% to $2.88 billion, partly because of tariff-related customer refunds. That decline interrupted a recent growth engine even though Tesla said demand and backlog remained strong. Services and other revenue was the bright spot, rising 33% to $4.61 billion and producing a record $734 million of gross profit.

Spending rose faster than sales. Operating expenses increased 39% to $4.78 billion. Capital expenditures more than doubled to $4.73 billion as Tesla invested in AI compute, the Cybercab, Optimus, battery capacity and new factories. Free cash flow declined 62% to $1.53 billion despite $6.26 billion of operating cash flow.

The balance sheet still provides room to invest. Tesla ended the quarter with $45.45 billion in cash, cash equivalents and short-term investments, up 9% from a year earlier. That liquidity reduces near-term financing pressure, but it does not answer whether the new projects will earn attractive returns.

Management is trying to shift the profit mix from vehicle hardware toward software, autonomous fleets and robotics. The quarter shows the transition's cost before those businesses contribute at scale. Optimus entered early production in Fremont, Cybercab began operating in Austin, and active FSD subscriptions rose 67% to 1.74 million. Those are operating milestones, not yet replacements for automotive earnings.

Investors should watch operating margin, free cash flow and evidence of paid autonomy usage together. A higher subscription count or robot production target has limited value if expenses continue to rise faster than revenue. Tesla retains a large cash cushion, but the third quarter makes clear that its next phase is capital intensive and execution dependent.
