The quarter was, by most measures, excellent. Broadcom reported Q2 revenue of $22.19 billion on June 3, up 48% year-over-year, with AI semiconductor sales reaching $10.8 billion — a 143% increase from the same period a year earlier, and above the company's own forecast. Adjusted EPS came in at $2.44, beating the Wall Street consensus of $2.39.

The stock dropped 14% after hours.

The problem was not what Broadcom reported. It was what Broadcom declined to promise. CEO Hock Tan maintained the company's full-year fiscal 2026 AI chip revenue guidance at $56 billion — short of the analyst consensus estimate of $57.6 billion. Q3 AI chip guidance came in at $16 billion, below the $17.2 billion analysts had penciled in. In a market that had spent two months pricing in perpetual upside revisions, a held number read as a miss.

When the ceiling becomes the story

Two other disclosures from the earnings call accelerated the after-hours slide. Tan acknowledged that Google would likely draw on multiple chip suppliers going forward. He also flagged that the rapid growth in AI semiconductor revenue was diluting the company's overall gross margins — a structural tension that tends to make long-duration investors uncomfortable. Tan framed it plainly: it was the mix shift, specifically the ratio of high-volume AI silicon to higher-margin software, that was compressing the blended figure.

Broadcom did guide Q3 consolidated revenue at $29.4 billion, implying 84% year-over-year growth and topping the $28.25 billion analysts had expected. Free cash flow hit a record $10.26 billion in Q2, representing 46% of revenue. The company ended the quarter with $19.6 billion in cash. For fiscal 2027, Tan reiterated a target of more than $100 billion in AI chip revenue.

None of it was enough to stop what happened Friday.

The contagion ran wide

By the end of the June 6 session, the Nasdaq Composite had dropped 4.18% — its largest single-day decline since the tariff turmoil of early 2025 — closing at 25,709.43. The S&P 500 fell 2.64% to 7,383.74. The Dow dropped 695.15 points to 50,866.78, ending at 50,866.78. The losses pushed the S&P 500 to its first losing week in ten.

Chip stocks absorbed the worst of it. Over the two trading sessions following Broadcom's earnings, Micron Technology fell 17%, AMD dropped 12.6%, and Intel slid 9%. The sell-off crossed the Pacific: South Korea's Kospi ended Friday's session down 5.54% at 8,160.59, with Samsung Electronics falling 6.40% and SK Hynix dropping 9.92%.

A May jobs report released Friday morning added a second variable. The U.S. economy added 172,000 jobs in May — nearly double the 85,000 economists had expected — while the unemployment rate held at 4.3%. The stronger-than-expected reading reduced the likelihood of near-term Federal Reserve rate cuts and pushed Treasury yields higher, compounding the pressure on growth stocks already trading at elevated multiples.

Broadcom's situation is not unusual for companies at the leading edge of an AI build-out cycle: the underlying business is accelerating, but the stock had priced in something faster. With AI semiconductor companies and their customers all eyeing mega-capex plans through 2027 and beyond, the math of expectation management is getting harder. For small businesses evaluating AI chip investments — or service providers whose vendor costs are tied to hyperscaler infrastructure pricing — the dynamic matters: when the companies setting the price of AI compute miss their own guidance bars, the downstream pricing environment becomes less predictable, not more.

Broadcom's fiscal year ends in October. The Q3 report, and whether Tan chooses to raise the $56 billion full-year target then, will answer the question the market is currently refusing to leave open.
