Great Earnings, Big AI Story… So Why Did Broadcom’s Stock Crash?
On paper, Broadcom’s latest earnings release looked like a victory lap.
The company delivered almost a perfect score for Q4. Revenue hit $18.02 billion (up 28% year-over-year), and EPS came in at $1.95, comfortably beating the guidance of $1.87. Management even raised guidance for the next quarter, forecasting revenue of approximately $19.1 billion and signaling continued growth ahead.
The engine behind this success? AI semiconductors.
On the earnings call, the CEO highlighted that Q4 growth was driven by a massive 74% increase in AI-related semiconductor revenue. Looking ahead to Q1 of fiscal 2026, AI semi revenue is expected to double year-over-year to about $8.2 billion. On top of that, Broadcom boasts an AI-related backlog of $73 billion scheduled for delivery over the next 18 months.
Fundamentally, this reads like a textbook "AI winner" story. A huge pile of booked business with room for upside. So, why did the market panic?
The Market’s Reaction: Brutal for a “Perfect” Quarter
Despite the stellar headline numbers, investors didn't celebrate. Before the report, Broadcom (AVGO) traded near highs of $412. After the release, the stock plunged more than 11% in a single day.
This move erased over $200 billion in market cap, dropping from around $1.95 trillion to $1.73 trillion. Valuation compressed sharply as the P/E ratio fell from roughly 112 pre-earnings to around 76. Following the recent volatility with Oracle, this felt like a second punch to the broader AI trade.
The reason for the sell-off wasn't in the numbers, but in the narrative revealed during the conference call.
What Spooked Investors: 3 Key Takeaways
Many analysts argue that the reaction was driven by the tone and specific admissions made by management regarding margins, timelines, and supply.
1. The Reality of "Lower AI Margins"
Management acknowledged a critical detail: AI-related business currently commands lower margins than other legacy parts of the company.
They guided that gross margins would drop by about 1 percentage point next quarter, largely because AI’s share of the total business mix is rising. Broadcom often ships entire systems or racks (including memory and modules), making it harder to maintain the sky-high software-like margins investors love.
While a 1% drop isn't catastrophic, it was a psychological blow to a market priced for "AI = Super High Margins." Investors heard: "AI revenue is growing fast, but the profit per dollar isn't as juicy as we hoped."
2. OpenAI Revenue: A 2026 Story
An analyst asked the multi-billion dollar question: When will revenue from the OpenAI partnership show up meaningfully?
Given the hype, many expected near-term upside. The CEO’s answer, essentially, was "at least two years out." The "OpenAI jackpot" is now explicitly framed as a long-term story rather than a catalyst for the next few quarters. For short-term traders, this was a signal to sell.
3. Supply Chain Caution
When asked about the ability to fulfill the $73 billion backlog given global constraints at foundries like TSMC, the CEO was cautious rather than confident.
Instead of a clear roadmap, the message was: "So far things are fine, but we'll see." This reminded investors that Broadcom is not immune to global supply bottlenecks. There is a real execution risk in delivering all that hardware on time.
The Bigger Issue: Expectations vs. Reality
With Broadcom, the market is realizing that the company helped push expectations too high. Broadcom doesn't break out "AI revenue" as a clean line item. Instead, they lump switches, optical components, and other hardware into the "AI semiconductor" bucket. It’s not just pure silicon chips.
We’ve now learned that the margins on this broader basket of products are not dramatically higher than legacy products—in some cases, they are lower due to scale and complexity. While management wasn't misleading investors, they leaned hard into the AI narrative, only for the economics to appear more "ordinary" than the hype implied.
Final Thoughts: What This Drop Tells Us
The market's message is clear: Investors are tired of AI stories that lack high-quality profitability.
Broadcom stock was up nearly 70% this year before the drop. The 11% correction suggests a shift in how the market values AI stocks. Moving forward, the focus will be less on "How fast is revenue growing?" and more on:
This is where the next phase of AI stock sorting will likely happen—prioritizing quality of earnings over just headline growth.
