Documented cause
Lululemon acquired Mirror for $500M in June 2020 at peak pandemic fitness boom. Post-pandemic gym reopenings cratered demand; Mirror reported only $74M in revenue in 2022 against projections of $250M+. Lululemon wrote down the asset by $443M in 2022 and fully discontinued the Mirror product line in July 2023, pivoting to a digital-only app strategy. Hardware unit economics never scaled.
Lesson
“Pandemic-driven hardware demand is a temporary spike, not a sustainable market signal.”
