Just saw Zillow stock getting hammered today - down about 17% after they guided lower on earnings. Interesting because their actual business looks solid. Rental revenue jumped 45% and mortgage business grew 39% in Q4, so the growth story is definitely there. Revenue hit $654 million, up 18% year over year. But here's what spooked people: management's saying legal costs are going to take a 2 percentage point bite out of their EBITDA margins in Q1. Wall Street was expecting around $184 million in adjusted EBITDA, and Zillow's guiding for $160-175 million instead. That's a meaningful miss. The company's rental and mortgage segments are clearly doing the heavy lifting - their adjusted EBITDA actually climbed 33% to $149 million in Q4. Management sounds confident about their legal positions, saying they don't expect material long-term impact. But the market didn't buy it today. Classic case of strong fundamentals getting overshadowed by near-term headwinds. Worth watching how this plays out in Q1.
