Broadcom's Q3 guidance missed expectations by $1.2 billion, dropping over 13% in after-hours trading—is the AI narrative "cooling off"?

Original Author: Ada, Deep Tide TechFlow

After the market close on June 3rd Eastern Time, Broadcom reported its fiscal 2026 second-quarter results for the period ending May 3, 2026. In absolute terms, this was a record-breaking quarterly report. Revenue reached $22.19 billion, up 48% year-over-year, the company's highest single-quarter growth rate since January 2017; adjusted EPS was $2.44, exceeding the analyst consensus estimate of $2.40. However, the market's focus was not on Q2, but on Broadcom's Q3 AI chip revenue guidance of $16 billion, representing over 200% year-over-year growth, yet falling nearly 7 percentage points short of the sell-side consensus of $17.2 billion. This gap, along with a slight miss in the company's software business, triggered a sharp stock price reaction.

Q2 Results Nearly Perfect, AI Semiconductor Revenue Grows for 13 Consecutive Quarters

According to Broadcom's official disclosure, Q2 AI semiconductor revenue reached $10.8 billion, up 143% year-over-year, exceeding the company's guidance of $10.7 billion given in March. CEO Hock Tan stated in the earnings release that the quarter's growth was driven by a "dual engine of custom AI accelerators and AI networking demand."

By segment, semiconductor solutions revenue was $15.009 billion, up 79% year-over-year, accounting for 68% of total revenue; AI semiconductor revenue now accounts for 72% of this segment, while non-AI semiconductor revenue was $4.2 billion, up 6% year-over-year, with a backlog exceeding $6 billion, indicating a cyclical recovery. Infrastructure software revenue (i.e., VMware) was $7.178 billion, up 9% year-over-year, in line with the company's own guidance but below the StreetAccount analyst estimate of $7.32 billion, a shortfall of approximately $140 million.

Profitability was also robust. Adjusted EBITDA reached $15.2 billion, or 69% of revenue, a new historical record; free cash flow was $10.26 billion, or 46% of revenue; quarter-end cash balance was $19.63 billion, an increase of $5.4 billion quarter-over-quarter.

Q3 Revenue Guidance Beats Expectations, But AI Semiconductor Revenue Falls "Short by $1.2 Billion"

Broadcom's Q3 guidance for total revenue is $29.4 billion, up 84% year-over-year and above the analyst consensus estimate of $28.54 billion; it guides semiconductor revenue of $20.5 billion, up 124% year-over-year. However, the AI semiconductor revenue guidance of $16 billion is 7% lower than the sell-side consensus estimate of $17.2 billion compiled by LSEG and other firms; the gap is even wider compared to some more optimistic buy-side expectations.

More critically, Hock Tan did not raise the fiscal 2026 AI chip revenue guidance during the conference call. According to a CNBC report, he reiterated during the call that "the company expects this momentum to continue into fiscal 2027 and maintains the guidance for AI semiconductor revenue exceeding $100 billion unchanged." Bernstein analyst Stacy Rasgon commented that it was the Q3 AI performance guidance that dragged down Broadcom's stock price.

Summing up the realized revenue from Q1 ($8.4 billion) and Q2 ($10.8 billion) with the expectations for Q3 and Q4, Broadcom's total AI chip sales for this fiscal year are projected to be around $56 billion, still roughly a $1.6 billion gap compared to the analyst consensus estimate of $57.6 billion.

Down Over 13% in After-Hours Trading, Options Market Had Already Priced in Volatility

Broadcom's stock price reacted sharply in after-hours trading. Following the earnings release at 4 PM Eastern Time on June 3rd, AVGO initially dropped about 5%; as details from the conference call emerged, losses widened, with the stock plunging over 15% at one point before closing down 13.78%. Based on a pre-earnings closing price of approximately $479, the single-day market cap loss exceeded $270 billion.

Notably, the capital market was already preparing for significant volatility after Broadcom's earnings. According to multiple media reports, the options market had priced in a single-day movement of around 7.8% for Broadcom following its earnings report, significantly higher than the historical average. This pricing reflected investor dilemma, as Broadcom's stock had rebounded over 60% from its March lows before entering earnings season, was up nearly 40% year-to-date in 2026, and its valuation (approximately 90x P/E) was far above the semiconductor peer average of around 69x.

Due to this valuation concern, the implicit threshold set by the market for Broadcom's earnings was "a comprehensive blowout performance." Any guidance falling short of "stellar" results could trigger profit-taking.

AI Networking Revenue Share Expected to Drop from 40% to 30%

For the A-share optical module sector, Hock Tan's remarks on the AI networking business during the conference call could be more damaging than the overall AI guidance.

According to Yahoo Finance citing the conference call, Hock Tan confirmed that the AI networking business accounted for "nearly 40%" of AI semiconductor revenue this quarter. However, he also stated that he expects this share to "normalize over time towards the 30% level, rather than staying around 40%."

This is the first time Broadcom management has clearly outlined a declining path for the AI networking revenue share. AI networking (including Ethernet switch chips, optical transceiver connection chips, etc.) precisely underpins the downstream narrative for the core revenue sources of A-share optical module leaders Zhongji Innolight, Eoptolink Technology, and TFC Communication. These three companies' stocks have risen sharply this year, with their combined market cap once surpassing that of Kweichow Moutai. Zhongji Innolight's forward P/E is around 66x, while TFC Communication's reaches 139x, valuation assumptions built on expectations of sustained high growth in AI networking.

Hock Tan's latest statement implies that even if AI computing power demand remains strong, the share of the networking segment may be the first to peak. If buy-side investors accept this signal, the previous valuation premiums of A-share optical module leaders will face a direct test.

Contagion Effect: Marvell Follows in After-Hours Trading, Asian AI Chain Under Pressure Today

The impact of Broadcom's guidance is already spreading. Marvell's stock fell about 9% in after-hours trading, narrowing to approximately 6% as of press time. Other companies in the AI networking/connectivity space, such as Astera Labs and Credo Technology, also faced pressure after hours. It's worth noting that Marvell surged 32% on June 2nd after Nvidia CEO Jensen Huang called it the "next trillion-dollar company," and its regular stock continued to rise 3.73% on June 3rd, but the after-hours pullback suggests the previous day's "Nvidia premium" faced concentrated profit-taking pressure.

For Asian markets, the core focal points today are twofold. First, whether the A-share optical module leader trio ("Yi, Zhong, Tian") can digest Hock Tan's comments about the declining share of networking. Second, whether South Korean stocks like SK Hynix and Samsung Electronics, the HBM suppliers, will be dragged down by the overall cooling of the AI narrative. Considering that Zhongji Innolight's single-day trading volume on June 2nd exceeded the entire day's volume of half of the A-share market, the sector's emotional reaction could be amplified.

However, the earnings report itself did not negate the long-term prosperity of AI computing power. Hock Tan again described AI chip demand as "insatiable" during the conference call and reiterated the goal of exceeding $100 billion in AI chip revenue by fiscal 2027. Institutions like UBS also adopted a "buy the dip" logic last December after a similar post-earnings decline in Broadcom's stock. Whether this round of correction marks a narrative inflection point or simply routine profit-taking in high-valuation stocks requires observation of subsequent conference calls from leading companies and capital expenditure trends of hyperscale cloud providers.
