Key Points

  • Fiscal third-quarter revenue and adjusted earnings per share (EPS) soared 62% and 60%, respectively, year over year, surpassing Wall Street's expectations.
  • Q4 guidance also exceeded the analyst consensus estimates on the top and bottom lines.
  • Nvidia's report indicates that the outlook for the AI market in general remains robust.

Shares of Nvidia (NASDAQ: NVDA) are up 4.5% in Wednesday's after-hours trading as of 5:57 p.m. ET, following the artificial intelligence (AI) tech leader's release of its report for its third quarter of fiscal 2026 (ended Oct. 26, 2025).

Investors' positive reaction is attributable to Q3 revenue and adjusted earnings per share both beating Wall Street's estimates, and Q4 guidance for both the top and bottom lines also coming in higher than analysts had expected.

The strong guidance was probably the most significant catalyst for Nvidia stock's upward move. It's an indication that the outlook for the AI market in general remains robust.

In recent weeks, Nvidia and other AI stocks have been struggling. Investors have become increasingly concerned about AI stock valuations, fearing that an AI stock bubble may be forming. These struggles were in part caused by the Nov. 4 revelation that Michael Burry, now a former hedge fund manager, took bearish positions (by buying put options) on Nvidia and Palantir stocks in the third quarter. 

Nvidia's key numbers

Metric Fiscal Q3 2025 Fiscal Q3 2026 Year-Over-Year Change
Revenue $35.08 billion $57.01 billion 62%
GAAP operating income $21.87 billion $36.01 billion 65%
GAAP net income $19.31 billion $31.91 billion 65%
Adjusted net income $20.01 billion $31.77 billion 59%
GAAP earnings per share (EPS) $0.78 $1.30 67%
Adjusted EPS $0.81 $1.30 60%

Generally accepted accounting principles (GAAP) numbers include one-time items. Investors should focus on the adjusted numbers, which exclude one-time items.

Wall Street was looking for adjusted EPS of $1.26 on revenue of $55.09 billion, so Nvidia exceeded both expectations. It also beat its own guidance, which was for adjusted EPS of $1.22 on revenue of $54 billion.

For the quarter, GAAP and adjusted gross margins were 73.4% and 73.6%, respectively.

Platform performance

Platform Fiscal Q3 2026 Revenue Year-Over-Year Change Quarter-Over-Quarter Change
Data center $51.22 billion 66% 25%
Gaming $4.27 billion 30% (1%)
Professional visualization $760 million 56% 26%
Automotive $592 million 32% 1%
OEM and other $174 million 79% 1%
Total $57.01 billion 62% 22%

The data center platform's performance was driven by "three platform shifts -- accelerated computing, powerful AI models, and agentic applications," Colette Kress said in her CFO commentary. She added that "Blackwell Ultra is now our leading architecture across all customer categories while our prior Blackwell architecture saw continued strong demand."

The 1% sequential slip in gaming revenue is no cause for concern. Kress said that distribution channels have reached "more normalized levels heading into the holiday season."

Professional visualization had a strong quarter, driven by the launch of the company's new DGX Spark (a compact AI supercomputer) and the growth of Blackwell sales.

Auto revenue growth was driven by the continued adoption of Nvidia's self-driving platforms, which are widely adopted by car companies and others developing driverless technology and driverless vehicles.

What the CEO had to say

CEO Jensen Huang stated in the earnings release:

Blackwell sales are off the charts, and cloud [computing] GPUs [graphics processing units] are sold out. Compute demand keeps accelerating and compounding across training and inference -- each growing exponentially. We've entered the virtuous cycle of AI. The AI ecosystem is scaling fast -- with more new foundation model makers, more AI start-ups, across more industries, and in more countries. AI is going everywhere, doing everything, all at once.

Guidance for the fourth quarter

For Q4 of fiscal 2026, which ends in late January, management expects revenue of $65 billion, representing a year-over-year growth rate of 65%.

Management also guided (albeit indirectly, by providing several inputs) for adjusted EPS of $1.50, representing 69% growth.

Going into the report, Wall Street had been modeling for Q4 adjusted EPS of $1.43 on revenue of $61.84 billion, so the company's outlook sprinted by both expectations.

Nvidia stock is not in a bubble

In short, Nvidia delivered yet another report with fantastic quarterly results and strong guidance.

Nvidia stock is not in a bubble. Shares were priced at 52 times trailing one-year earnings and 27 times forward one-year earnings at the close of Wednesday's regular trading session. These are reasonable valuations for a company that has just grown its quarterly adjusted EPS by 60% and guided for adjusted EPS growth of 69% next quarter.
