Arm Holdings faces a sharp margin slide as revenue rose 23% in fiscal 2026 but R&D and operating costs surged 43% and 33%, respectively, shrinking its operating margin by 370 basis points to 43%. The stock has slipped 10%, signaling a shift from royalty‑based growth to a scrutiny of silicon spend.

Supply constraints on memory, wafers, and packaging threaten Arm’s ability to meet a doubled demand forecast of $2 billion through fiscal 2028. Analysts note that while wafer supply is within Arm’s influence, memory shortages could keep customers hesitant to lock in orders, keeping revenue projections conservative.

Snap’s advertising arm shows muted headline growth, yet after adjusting for Middle East‑related disruptions, revenue could have risen 4‑5% instead of the reported 3%. Lower‑funnel ad products and a growing small‑to‑medium business customer base suggest underlying strength, prompting analysts to maintain a buy rating.

These developments underscore that investors now weigh operational discipline and supply chain resilience more heavily than past royalty narratives, reshaping valuation expectations for both firms.
