Subscription StickinessNarrow moat

Broadcom's infrastructure software — the mainframe and enterprise tools of CA, the security assets of Symantec, and above all¹ VMware's virtualization platform — sells on multi-year subscriptions to businesses that depend on it to run their operations. This software is mission-critical, deeply embedded in customers' data centers, and painful to replace, which makes the subscription revenue exceptionally sticky. Enterprises do not lightly rip out the software their entire IT infrastructure is built upon.

The stickiness rests on the same logic as Broadcom's chip franchises: high switching costs on critical infrastructure. Migrating off VMware or a core CA mainframe tool means re-architecting systems, retraining staff, and risking disruption to operations that must not go down — a project so costly and dangerous that most enterprises renew rather than attempt it. The subscription model turns that reluctance into a predictable, recurring stream of high-margin revenue that renews year after year with little effort.

The caveat is that stickiness born of switching cost is strong but not absolute, and Broadcom's aggressive pricing tests it directly. Every large price increase raises the reward for undertaking the painful migration, and enough customers, pushed hard enough, will decide the pain is worth it — especially where cloud-based or open-source alternatives have matured into genuine substitutes. So the software revenue is genuinely sticky and valuable, but its stickiness is a wall that Broadcom's own pricing strategy is constantly testing the height of.
