GlobalFoundries: A $21 Billion Headline, a Different Earnings Question
Japan-funded fabs, the separate equity agreement, a recovery below the 200-day average, and the earnings behind the headline.
In short
- GFS was $48.37, up 3.58% at 2:00 p.m. ET while SPY and QQQ were lower; the quote is separate from completed daily candles.
- Up to $21 billion is project investment, alongside separate CHIPS reallocation and equity arrangements; it is not immediate GF revenue or profit.
- Q2 revenue rose 5.81%, while IFRS operating profit fell 11.22%. Plan-linked sales and an automatic dividend-reinvestment purchase need their footnotes.

What “checked against the data” means
We compare public claims with numbers we can show. We do not promise returns, execute trades or hold funds.
Common questions
What does YieldTerminal actually do?+
It checks claims about the market against data and publishes the result either way. The Claim Checker runs popular trading rules on decades of daily prices. The daily stock review reads one company at a time. The movers, earnings and weekend pages report what happened rather than predict what happens next.
Is any of this financial advice?+
No. Everything here is educational commentary. YieldTerminal does not connect to a brokerage account, hold funds, or place orders, and it does not tell you what to buy or sell.
What is in the newsletter?+
One free email on Sunday with the week's reviews and research. You can unsubscribe from any issue.
Are the calculators free?+
Yes. The covered call and cash-secured put calculators are free and need no signup. Saving trades and the weekly Income Flow view require an account.
Do I need to understand an options chain to use them?+
No. You enter the stock price, strike, premium and expiration details from your broker. The calculators show the main outcomes in plain language before you place anything through your own broker.
