Broadcom's Q3 Guidance Falls $1.2 Billion Short of Expectations, Post-Market Drop Exceeds 13% — Is the AI Narrative 'Cooling Off'?
- Core Thesis: Broadcom's fiscal Q2 2026 results hit a record, but its Q3 AI semiconductor revenue guidance of $16 billion fell short of market expectations of $17.2 billion, triggering a post-market stock plunge of over 13%. This also impacted the AI networking-related supply chain, including A-share optical module stocks.
- Key Elements:
- Broadcom's Q2 revenue reached $22.19 billion, up 48% year-over-year, with AI semiconductor revenue hitting $10.8 billion, up 143% year-over-year, both exceeding guidance. Profit performance was also strong, with adjusted EBITDA reaching $15.2 billion.
- Q3 AI semiconductor revenue guidance of $16 billion fell below the analyst consensus estimate of $17.2 billion. The company did not raise its full-year AI chip revenue guidance, maintaining its target of over $100 billion for fiscal 2027.
- CEO Hock Tan, for the first time, stated that the AI networking business's revenue share would decline from 40% to 30%. This directly pressures the valuations of A-share optical module leaders (such as Zhongji Innolight), which rely on the AI networking narrative.
- Broadcom fell 13.78% in post-market trading, wiping out over $270 billion in market cap. The options market had already priced in a 7.8% move, and AI networking concept stocks like Marvell followed suit, falling about 6% in after-hours trading.
- Despite the lower-than-expected guidance, Hock Tan still described AI chip demand as "insatiable." UBS and other institutions believe that high valuations may be the primary reason for profit-taking, and the long-term outlook has not been negated.

After the market close on June 3, Eastern Time, Broadcom announced its fiscal year 2026 second-quarter results for the period ending May 3, 2026. By absolute numbers, this was a record-breaking quarterly report. Revenue reached $22.19 billion, up 48% year-over-year, marking 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 wasn't on Q2, but on Broadcom's Q3 guidance for AI chip revenue: $16 billion, representing over 200% year-over-year growth, but nearly 7% below the sell-side consensus estimate of $17.2 billion. This gap, coupled with a slight miss in the company's software business, triggered a sharp stock price reaction.
Q2 Results Near 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 previous guidance of $10.7 billion given in March. CEO Hock Tan stated in the earnings release that the quarter's growth was driven by "dual drivers 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 comprises 72% of this segment. 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 consensus of $7.32 billion, a gap of approximately $140 million.
Profitability was also strong. 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, up $5.4 billion quarter-over-quarter.
Q3 Revenue Guidance Beats, But AI Semiconductor Revenue 'Misses by $1.2 Billion'
Broadcom's Q3 guidance for total revenue is $29.4 billion, up 84% year-over-year, above the analyst consensus of $28.54 billion; semiconductor revenue guidance is $20.5 billion, up 124% year-over-year. However, the AI semiconductor revenue guidance within this is $16 billion, which is 7% below the sell-side consensus estimate of $17.2 billion compiled by LSEG and other agencies; the gap is even wider compared to some more optimistic buy-side expectations.
More critically, Hock Tan did not raise the fiscal year 2026 AI chip revenue guidance during the earnings call. According to a CNBC report, he reiterated in the call that "the company expects this momentum to continue into fiscal 2027 and maintains its guidance for AI semiconductor revenue to exceed $100 billion unchanged." Bernstein analyst Stacy Rasgon commented that it was the Q3 AI performance guidance that weighed on Broadcom's stock.
Summing up the realized revenue from Q1 ($8.4 billion) and Q2 ($10.8 billion), along with expectations for Q3 and Q4, Broadcom's total AI chip sales for the current fiscal year are projected to be around $56 billion, still about a $1.6 billion gap from the analyst consensus estimate of $57.6 billion.
Down Over 13% After Hours, Options Market Had Already Priced in Significant Volatility
Broadcom's stock reacted violently in after-hours trading. After the earnings release at 4:00 PM Eastern Time on June 3, AVGO initially dropped about 5%; as details of the guidance from the earnings call were disclosed, the decline widened, 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 erosion exceeded $270 billion.
It's worth noting that the capital market was already preparing for significant volatility following Broadcom's earnings report. Citing multiple media reports, the options market before the earnings release had priced in a single-day swing of around 7.8% for Broadcom post-earnings, significantly higher than the historical average. This pricing reflected investor dilemma; before entering the earnings season, Broadcom's stock had rebounded over 60% from its March lows, gaining nearly 40% year-to-date in 2026, with a valuation (around 90x P/E) far exceeding the semiconductor peer average of about 69x.
Precisely due to this valuation concern, the market's implicit bar for Broadcom's earnings report was a "comprehensive blowout," and any guidance falling short of a "stellar" performance could trigger profit-taking.
AI Networking Revenue Share to Drop from 40% to 30%
For the A-share optical module sector, Hock Tan's remarks on the AI networking business during the earnings call may be more impactful than the overall AI guidance.
According to the earnings call transcript cited by Yahoo Finance, Tan confirmed that the AI networking business accounted for "close to 40%" of AI semiconductor revenue this quarter. However, he also stated that he expects this proportion to "normalize over time to the closer to 30% level rather than staying around 40%."
This is the first time Broadcom management has clearly outlined a downward path for the AI networking business's share. AI networking (including components like Ethernet switch chips and optical transceiver connection chips) is precisely the downstream narrative corresponding to the core revenue sources of Chinese A-share optical module leaders: Zhongji Innolight, Eoptolink Technology, and T&S Communications. These three companies' stocks have risen significantly this year, with their combined market cap once surpassing that of Kweichow Moutai. Zhongji Innolight has a forward P/E of about 66x, while T&S Communications 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 robust, the share of the networking segment may peak first. If this signal is accepted by buy-side investors, the previous valuation premium of A-share optical module leaders will face a direct test.
Contagion Effect: Marvell Follows Decline After Hours, 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 before narrowing to around 6% as of press time. Other AI networking/connectivity concept stocks like Astera Labs and Credo Technology also faced pressure after hours. It's worth noting that Marvell had surged 32% on June 2 after NVIDIA CEO Jensen Huang called it the "next trillion-dollar company," and its regular shares continued to rise 3.73% on June 3. However, this after-hours pullback suggests the previous day's "NVIDIA premium" is facing concentrated profit-taking pressure.
For the Asian market, 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 on the decline in the networking share. Second, whether South Korean stocks like SK Hynix and Samsung Electronics, as HBM suppliers, will be dragged down by the overall cooling of the AI narrative. Considering the capital concentration where Zhongji Innolight's single-day trading volume on June 2 exceeded the entire daily 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 the demand for AI chips as "insatiable" during the earnings call and reiterated the goal of AI chip revenue exceeding $100 billion by fiscal 2027. Institutions like UBS also entered a "buy the dip" logic following a similar post-earnings decline for Broadcom last December. Whether this round of pullback is a narrative inflection point or a routine profit-taking event for high-valuation stocks requires monitoring subsequent earnings calls from leading companies and the capital expenditure trends of hyperscale cloud providers to determine.
