Broadcom Rises 13% Post Q3 Earnings: Buy, Sell or Hold the Stock?

Broadcom (AVGO) shares jumped 13% following strong Q3 fiscal 2025 results, with non-GAAP earnings up 28% and revenue up 22% year-over-year, primarily fueled by a 63% surge in AI revenues to $5.2 billion driven by demand for XPUs and a rich partner ecosystem. The company maintains a robust financial position with $10.72 billion in cash and strong free cash flow, supporting its growth initiatives. However, the outlook indicates a projected 70 basis point sequential decline in Q4 gross margins due to a higher mix of lower-margin XPUs, and a sluggish non-AI business, raising questions about its premium valuation despite significant AI-driven top-line momentum.

Analysis

Broadcom delivered a robust third-quarter fiscal 2025 performance, sending its shares up 13% on the back of significant top and bottom-line beats. Revenues grew 22% year-over-year to $15.95 billion, while non-GAAP earnings surged 28%, driven by exceptional demand in its artificial intelligence segment. AI-related revenues soared 63% year-over-year to $5.2 billion, fueled by its XPU custom silicon for key clients like Alphabet and Meta, and the company guides for this momentum to continue with a projected 66% AI revenue growth in Q4. This strength is underpinned by a consolidated backlog of $110 billion and a powerful financial position, evidenced by $7.02 billion in free cash flow and a $10.72 billion cash balance. However, this positive AI narrative is tempered by notable headwinds. The company projects a 70 basis point sequential decline in Q4 gross margin due to a higher mix of lower-margin XPUs, a pressure point expected to persist. Furthermore, the non-AI business remains sluggish, with a meaningful recovery not anticipated until mid-to-late 2026. These concerns, coupled with a premium valuation at a 22.01x forward price-to-sales ratio, create a complex picture where strong AI-driven growth is pitted against margin compression and weakness in other core segments.

Key Decisions for Investors

• Investors with a long-term bullish view on the AI infrastructure theme may consider holding Broadcom, given its formidable competitive position, a $110 billion backlog, and strong free cash flow generation that supports capital returns.
• It is critical to monitor the company's gross margin performance, as the guided sequential decline of 70 basis points due to product mix could signal a trend of eroding profitability despite strong top-line growth in AI.
• Given the stock's premium valuation and the noted weakness in the non-AI business, potential investors or those looking to increase their position should exercise caution and might consider waiting for a more favorable entry point, particularly if a broader market downturn or further margin pressure materializes.
