Vertiv

Vertiv's Top Stability & Growth Strengths

Strong Revenue Growth: Net sales rose sharply through 2025–Q2 2026 (e.g., Q1 up 30% and Q2 up 24% year over year), with full‑year 2026 guidance lifted to about $13.8–$14.2B and ~31% organic growth. Order surges in late 2025 and a larger backlog underscore sustained demand.

Strong Market Position & Advantage: Independent industry trackers consistently place Vertiv at or near the top in data‑center thermal management and as a leader in large three‑phase UPS and power distribution. Multiple sources describe Vertiv as co‑leading global DCPI with Schneider Electric, with share gains on strong North American demand.
