Plaintiffs say Wix overstated the strength of Base44 and Harmony while masking the cost of its AI push before a May 2026 margin miss sparked a 27% share drop.
Wix.com Ltd. (NASDAQ: WIX) is facing a proposed securities class action in federal court in Illinois on behalf of investors who bought or otherwise acquired the company's securities between Feb. 19, 2025 and May 12, 2026, with Sept. 22, 2026 set as the lead plaintiff deadline. The complaint alleges Wix overstated the competitiveness, performance and financial upside of AI offerings including Base44 and Wix Harmony while understating the cost of building and marketing them as competition from AI-driven website and app creation intensified. Plaintiffs point to a series of disclosures on May 21, 2025, Nov. 19, 2025 and May 13, 2026, culminating in first-quarter 2026 results that showed non-GAAP sales and marketing expense jumping 88% to $190.7 million, quarterly operating expenses rising 46% and non-GAAP operating margin falling to 5% from 21% a year earlier. The suit says the May 2026 disclosure helped drive a 27% share-price drop and more than $1.1 billion in lost market value as management acknowledged product gaps in Harmony and stronger competition for professional developer customers.
