Zscaler (ZS): Sacrificing free cash flow to hoard physical servers [Q4 2026]

Zscaler closed out Q4 2026 with record operating margins and incredible sales productivity, yet still chose to strategically torpedo its quarterly free cash flow to stockpile physical data center equipment.

In ~10 minutes:

• Why they accelerated $218.5M in CapEx to outrun processor inflation 💾

• How the new frictionless Z-Flex model bypassed procurement for $770M in TCV

• Why they are cutting 3% of the workforce during peak sales performance

• The CFO’s quiet write-off of the Red Canary acquisition’s net new ARR for FY27

Behind the massive software wins and AI-driven pipeline growth lies a deeply analog anxiety: to secure the cloud against autonomous rogue agents, you still need to physically own the metal to route the traffic.
