Earlier this morning, we released our fiscal 2026 fourth quarter and annual results, along with certain outlook information. Before I turn the call over, I'd like to note an update to our segment reporting implemented during the fourth quarter. As a result of the recent acquisition of Power Solutions, we are now reporting our business in two reportable segments: Communications and Building Systems. This new segment reporting reflects how Dycom's business is managed and the positioning of the company's strategies and expanding platform to provide comprehensive solutions as we address the growing demands for digital infrastructure.
The Communications segment provides specialty contracting services for telecommunications providers, underground facility locating services for various utilities, including telecommunications providers, as well as other construction and maintenance services for electric and gas utilities. The Building Systems segment provides comprehensive building infrastructure solutions, including electrical, energy management, security, and fire safety systems for data centers and other critical facilities. This segment includes the results of Power Solutions following the closing of the acquisition on December 23rd, 2025. Dycom's fourth quarter results are an excellent finish to a record year as we set new benchmarks across nearly every financial metric we track.
Our performance highlights our unique ability to capitalize on a diverse and intensifying demand environment. We delivered on the two pillars we set as priorities: meaningful margin expansion and improved operating cash flow. Our strategy and focus on scaled efficiencies strengthened our balance sheet and built a platform for sustained high-performance growth. Beyond our solid organic growth, we fundamentally broadened Dycom's reach through strategic M&A.
