Case Study: Cornerstone Building Brands achieves $1M+ in savings and 77% reduction in hours per control with Workiva

Cornerstone Building Brands Reconstructs Internal Audit and SOX Compliance, Saves $1M+

Cornerstone Building Brands, North America’s largest manufacturer of exterior building products formed by merger, faced a fragmented and time-consuming SOX and internal audit process. The combined company was managing roughly 2,500 Excel files across 25 business units, averaging about 30 hours per control, and had under 10 months to implement a unified SOX program.

Cornerstone fast-tracked a Workiva implementation to harmonize controls, centralize documentation and give auditors direct access to support. The platform cut time per control by 77% (to about seven hours), eliminated outside SOX consultant spend (from $1.5M in FY2019 to $0 in FY2020), improved executive visibility and auditor collaboration, and created a repeatable framework for future reporting.
