Ziff Davis, Inc. (ZD) experienced a significant after-hours plunge of 10.39% following the release of its fourth quarter and full year 2025 financial results.

The digital media company reported quarterly earnings that fell short of analyst expectations. Q4 revenue of $406.7 million missed the consensus estimate of $416.4 million, while adjusted EPS of $2.56 came in below the expected $2.71. Most notably, the company's net income for the quarter plummeted 99.4% year-over-year to just $0.4 million, impacted by a $58 million pre-tax loss on the sale of a business and a $19.7 million loss on an equity method investment.

Adding to investor concerns, the company announced it is deferring its fiscal 2026 financial guidance as it evaluates strategic options, including potential sales of entire divisions. This combination of earnings misses, a dramatic profit decline, and near-term uncertainty prompted the sharp sell-off in post-market trading.
