First quarter revenue is expected to be between $179 million and $181 million, representing year-over-year growth of 7% to 8%. First quarter revenue outlook reflects continued strong growth in Dealer revenue driven by continued adoption of the Cars Commerce suite of products, the D2C acquisition, and the full period impact of the 2023 Marketplace Repackaging Initiative. OEM and National Advertising spend is also expected to be up year-over-year, but historically has experienced some seasonality from the fourth quarter to the first quarter. For the year, the Company anticipates continued growth across its platform with both dealer and OEM customers which is reflected in its revenue growth guidance of 6% to 8%.
Adjusted EBITDA margin for the first quarter of 2024 is expected to be between 27% and 29%. It's important to note, the Company has seasonally higher investments in Marketing and sales in the first quarter, due to the timing of in-person industry events. The Company expects margins to improve over the course of the year and deliver a full year Adjusted EBITDA margin between 28% to 30%.
