Gross Margin Slips Amid AI Surge: AVGO's Growth Promises Show Cracks

What happened

Broadcom's Q2 FY26 results revealed a sequential gross margin contraction as semiconductor mix surged, despite an 84% revenue jump driven by AI chip demand. The Zacks article highlights that while top-line growth remains robust, margin compression raises questions about the sustainability of profitability as lower-margin hardware scales. The DeepValue report already warned of these pressures, noting inventory buildup to $4.3B and a $29B contingent backstop exposure that could further strain margins. The market's focus has shifted from pure AI hype to the quality and convertibility of earnings, with packaging bottlenecks and customer concentration (42% from one distributor) adding execution risk. In short, the margin erosion validates the thesis that AVGO's growth is increasingly costly and lumpy, reinforcing a wait-and-see stance until shipment conversion proves durable.

Implication

Over the next 6 months, AVGO's elevated valuation (63.8x P/E) leaves no room for margin deterioration. The gross margin contraction intensifies the need to monitor Q3 FY26 guidance achievement and any expansion of the $29B contingent liability. If margins stabilize and AI shipments meet targets, the stock may recover; otherwise, downside risk to $330 entry is material.

Thesis delta

Gross margin contraction is a new confirmed risk, not just a theoretical one. The base case's 50% probability now requires margin stability to hold; any further compression could shift probabilities toward the bear case. The long-term thesis remains intact but the near-term margin of safety narrows, making the WAIT rating more appropriate.
