Guidance, Outlook, and Risks
- Outlook: Management expects Residential revenue to decrease in absolute dollars in Q4 2025 due to seasonality. The company continues to invest in technology and human capital to drive growth.
- Strategic Initiatives: The partnership with Redfin for multifamily rental listings is a key growth driver, though it has increased lead acquisition costs. Zillow Home Loans is prioritizing purchase loan originations.
- Capital Allocation: As of September 30, 2025, $943 million remained available under share repurchase authorizations. The company repurchased $38 million of Class A stock in Q3.
- Risks & Contingencies:
- Legal Proceedings: The FTC and several state Attorneys General filed complaints alleging the Redfin partnership harms competition in multifamily rentals. Additionally, a federal securities class action regarding Zillow Offers remains pending appeal.
- Market Conditions: Performance remains sensitive to interest rates, housing inventory, and inflation. High mortgage rates continue to impact transaction volumes.
Investor Verification Checklist
- Redfin Partnership Impact: Verify the long-term ROI of the $100 million Redfin partnership payment and the sustainability of the increased lead acquisition costs.
- Legal Exposure: Monitor the status of the FTC antitrust complaint regarding the Redfin partnership and the securities class action appeal.
- Mortgage Margin Trends: Assess the stability of the "gain on sale margin" for Zillow Home Loans amidst fluctuating interest rates.
- Seasonality: Confirm Q4 2025 revenue guidance, specifically the expected decline in Residential revenue.
- Cash Position: Review the trajectory of cash and short-term investments given the recent debt settlements and continued share repurchases.
