Q1 2020 Financial Highlights
Total revenue decreased $38.1 million, or 5.5%, to $652.5 million in Q1 2020 compared to $690.6 million in Q1 2019 primarily due to a decrease in average unit volumes driven by a decrease in comparable restaurant sales. While store weeks increased 5.3%, comparable restaurant sales decreased 8.4%. The decrease in average unit volumes is primarily due to the temporary closure of our dining rooms in mid-March related to the pandemic.
