Down About 18% From Recent Highs, Is Broadcom Stock a Buy?

Broadcom shares slid about 18% after fiscal Q4 results and guidance as management warned that rapidly rising AI semiconductor sales—AI revenue up 74% YoY and guided to double to $8.2 billion in fiscal Q1—will be dilutive to gross margin (about a 1 percentage-point q/q hit) and trim adjusted EBITDA to ~67% from 68%. The firm still delivered strong top-line growth (revenue +28% to just over $18 billion; semiconductor solutions +35%; infrastructure software +19%) and generated $26.9 billion of free cash flow in FY2025 while returning $17.5 billion to shareholders and raising the dividend, but non‑AI semiconductor revenue is roughly flat so near-term growth is concentrated in lower‑margin AI products. With a roughly $1.6 trillion market cap and a forward P/E near 36, the stock appears priced for near‑perfect execution, leaving limited room for disappointment absent a meaningful valuation reset or several quarters of results above expectations.

Analysis

Broadcom reported fiscal Q4 revenue of just over $18 billion, up 28% year over year, with semiconductor solutions revenue rising 35% and infrastructure software up 19%. AI semiconductor revenue grew 74% YoY in the quarter and management guided AI semiconductor revenue to double year over year to $8.2 billion in fiscal Q1, while non‑AI semiconductor revenue is expected to be roughly flat.

Management warned that the higher mix of lower‑margin AI products will be dilutive to gross profit margin by about one percentage point sequentially and guided adjusted EBITDA to ~67% of revenue (down from 68% in Q4). The company still produced $26.9 billion of free cash flow in FY2025, returned $17.5 billion to shareholders (including $11.1 billion in dividends and $6.4 billion in buybacks), and raised the quarterly dividend 10% to $0.65, but faces a market capitalization near $1.6 trillion and a forward P/E around 36.

The market reaction—a roughly 18% decline from recent highs—reflects investor concern that rapid AI mix shift could compress margins and leave little room for execution misses given the elevated valuation; near‑term outcomes hinge on whether scale drives operating leverage to offset lower AI gross margins and sustain the current valuation.

Key Decisions for Investors

• Reassess position sizing and avoid initiating new full exposures at current levels given a forward P/E near 36 and explicit guidance for a ~1 percentage‑point gross‑margin hit,
• Require several quarters of margin stability or beats (monitor fiscal Q1 AI revenue versus the $8.2 billion guide, sequential gross margin change, and adjusted EBITDA %) before adding meaningfully,
• Consider hedging existing exposure (options or collars) to protect against further downside while the AI product mix and margin trajectory are being resolved,
• Monitor free cash flow generation and capital return cadence as a secondary support signal; increasing buybacks/dividends alongside stable margins would materially de‑risk the valuation case
