During the year ended December 31, 2024, the Spectrum segment completed the purchases of five Low Power Television licenses and stations for an aggregate consideration of $1.5 million, with $0.3 million payable on or before April 12, 2025. The acquisitions were accounted for as asset acquisitions.

The weighted-average period prior to the next renewal for FCC licenses was 5.4 years and 6.2 years as of December 31, 2024 and 2023, respectively, after taking into consideration licenses that were successfully renewed shortly after year-end. While broadcast television licenses are issued for a fixed period of time (generally eight years), renewals of these licenses have occurred routinely and at nominal cost. In addition, the Company does not believe that the expiration or non-renewal of any of its FCC licenses would have a material adverse effect on the expected future cash flows and profitability.

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
