Nexstar Media Group, Inc.

Nexstar Media Group, Inc.'s Top Stability & Growth Strengths

Strong Revenue Growth: Net revenue reached record levels in Q2 2026 with a sharp year-over-year increase following the March 2026 addition of TEGNA and stronger legacy distribution and advertising. First-half 2026 results also show meaningful top-line momentum versus the prior year.

Healthy Cash Flow: Adjusted EBITDA and free cash flow were robust in Q2 2026, and the company simultaneously paid dividends and reduced debt. These actions point to solid cash generation supporting both investment and shareholder returns.

Strong Market Position & Advantage: The company is the largest U.S. local TV broadcaster and expanded further by acquiring TEGNA, while also controlling The CW and operating NewsNation. This scale, coupled with a rising distribution mix, enhances negotiating leverage with distributors and advertisers.
