| 2026-10-08 | editorial note | Verdict changed: The business ran past the June bull case — Data Center +107%, a $13B Q3 guide, and management now guiding Data Center revenue to more than double in 2027 — while the stock rose only …Before (deep-dive-2026-09-25.md): The business ran past the June bull case — Data Center +107%, a $13B Q3 guide, and management now guiding Data Center revenue to more than double in 2027 — while the stock rose only ~18%, so the multiple compressed rather than expanded. The June "priced for perfection" charge is weaker than it was; what replaced it is a larger, more concentrated, more debt-and-prepayment-funded bet on one ramp (Helios/MI450) that has not shipped a rack yet. After (deep-dive-2026-10-08.md): AMD signed a merger agreement on 2026-09-26 to buy World Labs, Fei-Fei Li's spatial-AI lab, for about $8.2B paid entirely in AMD stock. The share count is not fixed; it floats on a 10-day VWAP ending two trading days before closing. At recent prices that is roughly 12.6M to 13.7M new shares, about 0.8% of the 1.632B shares outstanding, so the dilution is small next to the 320M-share OpenAI/Meta warrants. It is the largest of AMD's 2026 tuck-ins and its second-largest deal ever by press count, but it does not move the earnings path. Taalas and FastFlowLM are still NOT confirmed by any AMD SEC filing; only press reports and AMD's own (non-filed) announcements describe them. The thesis rides on Helios exactly as before. Direction WATCHING, conviction MEDIUM, unchanged. | dossier |
