Electrical distribution CSS backlog growth measures the year-over-year change in backlog for Wesco's Communications & Security Solutions segment.

Wesco reported approximately 95% CSS backlog growth at the end of the second quarter of 2026.

Data-center projects drove the increase

The company said record CSS backlog growth was driven by strong growth in data-center projects.

That makes backlog especially relevant as a forward-looking demand indicator for the segment, while still remaining distinct from recognized revenue.

Backlog is not booked sales

The metric remains subordinate to the generic backlog concept because orders can convert over different time horizons.

Read it with CSS organic sales growth and data center sales growth.
