Despite outstanding performance, Broadcom Inc. (AVGO.US), the "king of AI custom chips," has a valuation lower than its peers. Is it a value trap?

After NVIDIA Corporation ignited the market with its record-breaking quarterly report, the spotlight turned to Broadcom Inc. (AVGO.US). The worlds third-largest chip manufacturer delivered an equally stunning performance on September 2 revenue of $29.59 billion, up 86% year-over-year, and adjusted earnings per share of $3.32, both far exceeding Wall Street expectations. More impressively, its free cash flow margin reached a historic high of 46%, with free cash flow growth outpacing revenue growth by 9 percentage points. However, despite this "textbook" performance, Broadcom Inc.'s stock price has plummeted 23% since its June peak, with only a 6% increase for the year, while the Philadelphia Semiconductor Index surged 61% during the same period. With NVIDIA Corporation having proven that the AI narrative is far from over, Broadcom Inc. is becoming the most attractive "hidden gem" in the AI hardware space, trading at only 18.5 times earnings for fiscal year 2027, compared to its competitor in custom chips, Marvell Technology (MRVL.US), which has a forward P/E ratio of 33 times. Q3 Performance Crushes Expectations: Record Revenue of $29.59 Billion, Semiconductor Business Soars 127% Year-Over-Year Broadcom Inc.'s Q3 earnings for fiscal year 2026 thoroughly surpassed market expectations: Revenue: $29.59 billion, up 86% year-over-year, exceeding expectations by $156.5 million; Adjusted earnings per share: $3.32, exceeding expectations by $0.08; Semiconductor solutions business: Revenue of $20.8 billion, up 127% year-over-year, a historic high; Infrastructure software business: Revenue of $8.8 billion, up 29% year-over-year. The semiconductor solutions business is Broadcom Inc.'s core growth engine, accounting for 70% of consolidated revenue. This business includes products such as custom AI accelerators, Ethernet switch chips, broadband access devices, and wireless components. Among these, custom AI accelerators (ASICs) are growing at an astonishing rate Broadcom Inc.'s clients include Alphabet Inc. Class C (TPU), Meta (MTIA), and the recently onboarded Anthropic. During the earnings call, Broadcom Inc. CEO Hock Tan revealed that Anthropic is expected to become Broadcom Inc.'s largest AI accelerator client by 2027. Anthropic is actively expanding its AI computing power and has signed agreements with several hardware suppliers to meet the demands of its AI services. This signal further confirms Broadcom Inc.'s irreplaceability in the AI custom chip sector. Broadcom Inc.'s guidance for Q4 is also strong with expected revenue reaching $34.8 billion, up 93% year-over-year, and accelerating 7 percentage points quarter-over-quarter. With a free cash flow margin of 46%, Q4 free cash flow is expected to exceed $16 billion. Profitability: Record Free Cash Flow Margin of 46%, a Money-Making Machine in the "Burn Cash" Race In the AI hardware arena, most "neocloud" companies are still struggling with losses, while Broadcom Inc. demonstrates rare profitability: Free cash flow: $13.7 billion (for the quarter), free cash flow margin of 46%, an expansion of 2 percentage points year-over-year; Gross margin: consistently maintained at an extremely high level of around 75%; Annualized free cash flow run rate: at least $55 billion. Broadcom Inc.'s free cash flow is not only impressive in scale but more importantly, in growth quality free cash flow growth outpacing revenue growth by 9 percentage points indicates that Broadcom Inc.'s scale expansion is becoming increasingly profitable. This suggests that as the AI custom chip business scales, there may still be upward potential for Broadcom Inc.'s profit margins. Broadcom Inc. and NVIDIA Corporation are currently the only two companies in the AI hardware space with free cash flow margins exceeding 40%. Both benefit from the same data center growth trend, achieving significant leaps in revenue, gross profit, and net income in the past year. Valuation Severely Underestimated: 18.5 Times Forward P/E vs. Competitors' 33 Times Broadcom Inc.'s current stock price is around $357.90, and its forward P/E ratio based on fiscal year 2027 earnings estimates is about 18.5 times. This valuation is significantly undervalued in the AI hardware space. According to 49 analysts tracked by S&P Global, there is a consensus "strong buy" rating for Broadcom Inc., with an average target price of $533.41, indicating about 49% upside from the current stock price. Jefferies maintains a "buy" rating with a target price of $550; Huatai has set a target price of $550.22. Analysts believe that accounting for Broadcom Inc.'s growth potential in free cash flow in the AI custom chip sector, a reasonable valuation should be a forward P/E of 25 times. Based on the consensus EPS for fiscal year 2027 of $19.37, a P/E of 25 corresponds to a target price of about $484. Considering the earnings revisions driven by better-than-expected Q4 guidance, this target price still has room for further upward adjustment. Key Catalysts: Anthropic Orders, Alphabet Inc. Class C TPU Moat, and Market Share Expansion Broadcom Inc.'s growth narrative is built on three core pillars: First, Anthropic becoming the largest client by 2027. As a leading AI lab, Anthropic is rapidly expanding its computational infrastructure and has signed agreements with several hardware suppliers. Hock Tan confirmed in the earnings call that Anthropic is expected to surpass all existing clients in 2027, becoming the largest source of revenue for Broadcom Inc.'s AI accelerator business. Second, the irreplaceability of Alphabet Inc. Class C TPU. Although Alphabet Inc. Class C has incorporated Marvell into its custom chip supply chain, raising market concerns about Broadcom Inc.'s loss of share, Morgan Stanley analysts believe these concerns are "overstated." Given the five-year agreement signed in April 2026, Broadcom Inc.s position as a key TPU partner for Alphabet Inc. Class C will not be supplanted. The addition of more partners by Alphabet Inc. Class C is intended to support its in-house team and the TPU ecosystem expansion, rather than to replace Broadcom Inc. Third, the ongoing expansion of the custom chip market. With a surge in demand for AI inference, the market for custom chips (ASICs) is growing significantly faster than the GPU market. As the absolute leader in this market, Broadcom Inc. will continue to benefit from this structural trend, leveraging its deep ties with core clients like Alphabet Inc. Class C, Meta, and Anthropic. Core Risks: Concentration of Ultra-Large Clients and Margins on Free Cash Flow Broadcom Inc. faces core risks stemming from rising customer concentration. If ultra-large clients become more cautious with chip procurement agreements, Broadcom Inc. may face a significant slowdown in growth. As the AI custom chip business increasingly dominates, Broadcom Inc. is becoming more dependent on this sector. Another metric to watch is the free cash flow margin. If Broadcom Inc.'s free cash flow margin falls below 40% or gross margin drops below 70%, it will trigger fundamental scrutiny of the valuation logic. Additionally, Broadcom Inc. is negotiating with lending institutions to raise over $60 billion in debt for a financing transaction that would benefit Anthropic. This news has sparked market concerns about Broadcom Inc.'s "revolving financing" model similar controversies have previously pressured NVIDIA Corporation's valuation. Broadcom Inc. needs to find a balance between pursuing scale expansion and maintaining financial health. Conclusion Broadcom Inc.'s earnings report tells a story about the underestimated king of AI infrastructure. A record revenue of $29.59 billion, a 127% growth in the semiconductor business, and a 46% free cash flow marginthese figures alone are enough to demonstrate Broadcom Inc.'s dominance in the AI custom chip market. However, the stock price has plunged 23% from its June peak, the forward P/E for fiscal year 2027 stands at only 18.5 times, and the valuation premium of its competitor Marvell at 33 times together present a rare "value pit" signal. In a market landscape where NVIDIA Corporation trades at 14.9 times forward P/E and Marvell at 33 times, Broadcom Inc., as the leader in AI custom chips with the strongest free cash flow generation capabilities, is clearly undervalued relative to its growth potential. As one analyst stated, Broadcom Inc. benefits from the same AI data center growth trend as NVIDIA Corporation, with both achieving significant leaps in key indicators such as revenue, gross margins, and net profit. As NVIDIA Corporations record earnings demonstrate that the AI narrative is far from over, Broadcom Inc. a giant in AI infrastructure with a 75% gross margin, a 46% free cash flow margin, and backing from both Anthropic and Alphabet Inc. Class C is becoming the most attractive "hidden gem" in the AI hardware sector.
