GM Q3 2026 Earnings on October 20: What to Expect, and What GM Stock Did on Every Earnings Day Since 2011

General Motors reports third-quarter 2026 results on Tuesday, October 20, at about 6:30 AM Eastern, with the call at 8:30, so the stock reacts in the same session. Wall Street expects a much better quarter than a year ago even though GM sold fewer vehicles in the United States, and the stock has become one of the market's bigger earnings movers after a decade of barely reacting. This preview covers the time and what to expect, the numbers the report turns on, and what we measured about GM's stock on every report day since its 2010 listing. It is education, not advice.

When does GM report Q3 2026 earnings?

Tuesday, October 20, 2026. GM's investor relations notice puts the release at approximately 6:30 AM ET, before the market opens, with the conference call at 8:30 AM ET. Because the news lands before the open, the reaction happens on Tuesday itself, which is also the day Netflix reports after the close. Our week-ahead guide has the full schedule.

What Wall Street expects

Consensus going into the week is around $3.60 of adjusted earnings per share on roughly $48.8 billion of revenue, against $2.80 a share in the third quarter of 2025. GM has beaten the consensus estimate in each of the last twelve quarters, a streak that goes back to the third quarter of 2023, which is one reason the bar keeps moving up.

The company itself set the frame in July. Its second-quarter release showed revenue of $48.0 billion, net income of $1.3 billion and EBIT-adjusted of $3.9 billion, an 8.2% margin, with North America at $3.4 billion and 8.6%. It raised full-year 2026 guidance for the second time this year: EBIT-adjusted of $14 to $16 billion, adjusted EPS of $12 to $14, net income of $8.4 to $9.8 billion and adjusted automotive free cash flow of $9.5 to $11.5 billion. It also reported $2.8 billion of buybacks in the first half and kept the quarterly dividend at $0.18.

Three things the report turns on

• Fewer vehicles, more profit per vehicle. GM's own October 1 sales release reported 670,974 U.S. deliveries in the quarter, down 5.5% from a year earlier, while Silverado sales rose 13% and small SUVs set a record. The quarter is expected to show higher earnings on lower volume, which means the North America margin is the number to read first. If pricing and the truck mix held, the margin holds; if discounts crept in, it does not.
• EV volume and charges. GM's U.S. EV sales fell about 62% in the quarter, to roughly 25,000 from 66,500, after the federal credit ended and some models were discontinued. The question is whether the EV business cost more than planned, and whether there are new write-downs or capacity charges on top of the ones already taken.
• The guide. After two raises, the third quarter is where the full-year range either gets narrowed toward the top, held, or trimmed for tariffs and EV costs. Historically the guide, not the quarter, is what moves this stock by midday.

What GM stock has done on every earnings day since 2011

We took every quarterly earnings report GM has filed since its November 2010 IPO, 66 of them from February 2011 through July 2026, using the Form 8-K filing dates on SEC EDGAR, and matched each to the stock's close that day against the close before. GM reports before the open, so the report day is the reaction day.

• The stock rose on 34 of 66 report days (52%). The median move, up or down, was 3.5%.
• A 5% move happened 19 times out of 66; a 10% move only 2 times: a 10.9% drop in November 2011 and a 14.9% gain in October 2025, the largest earnings-day move in the company's listed history.
• The last twelve reports are a different stock. From the October 2023 report onward, the start of the beat streak, the median move has been 7.1%, more than double the 3.2% median of the 54 reports before it, and the stock rose after 7 of the 12. In order: -2.3%, +7.8%, +4.4%, -6.4%, +9.8%, -8.9%, -0.6%, -8.1%, +14.9%, +8.8%, +1.3%, +4.9%.
• October reports have leaned up. GM has reported in October 13 times and the stock rose on 9 of them, including +9.8% in 2024 and +14.9% in 2025. The two October losses of note were 2016 (-4.2%) and 2021 (-5.4%).

Why the change? For most of its listed life GM was priced as a steady, cheap automaker whose quarters rarely surprised. Since 2023 the stock has carried a debate about tariffs, EV losses and buybacks, so each report resolves more uncertainty and the reaction is bigger in both directions: four of the last twelve moves were drops of 6% or more, and four were gains of 7% or more.

Does the first day's move hold?

We also checked what happened in the five trading days after a big report-day move. After the 21 report days where GM rose 3% or more, the median gain measured from the pre-report close was +7.5% a week later, and the stock was above its report-day close one week on in 52% of cases. After the 18 report days where it fell 3% or more, the median one-week result was -5.0%, and the stock was below its report-day close a week later 50% of the time. In plain terms, a GM earnings move is about as likely to extend as to fade over the following week, so the first hour settles less than it seems to.

Where the stock sits going in

GM closed Friday, October 16 at $83.96, up about 3% for the year and about 7% below its July 28 closing high of $90.30. The last report in July produced a 4.9% gain on the day. The setup, then, is a stock that has already rewarded the last two reports, sitting below its summer high, with a consensus that assumes the beat streak continues. That is the kind of position where a merely in-line quarter can trade down, which the July 2024 and January 2025 reports showed: both were drops of 6% or more on quarters that were not disasters.

How to hold GM through the report

• Size for a 7% day, not a 3% one. The recent median is the honest expectation. A position that would hurt on a 7% gap is too big for Tuesday morning. Position sizing is the control that works before the open.
• A stop does not protect you through a pre-market release. GM reports at 6:30 AM and the stock opens at whatever price the report produces; a stop fills there. If you need protection across the release, reduce the position Monday, or accept the gap. The earnings-season guide covers the gap problem in detail.
• Write the four outcomes down on Monday. Gap up and extend, gap up and fade, gap down and extend, gap down and fade. GM's own record says each pair is close to a coin flip over the following week, so the plan matters more than the prediction. The earnings playbook has a template.
• Keep Tesla separate. Tesla reports Wednesday evening and the two stocks are often lumped together as 'autos'. They are not the same trade: our Tesla piece has that stock's record, which moves almost twice as much.

JorgAI exists for mornings like Tuesday's: the position cap, the stop, the profit target and the daily loss brake are set once and enforced inside your own brokerage account while the report lands. Set your rules before the open rather than after it.
