Wix.com Ltd. faces a securities class action in the U.S. District Court for the Northern District of Illinois after its shares fell 27% in mid-May following the company’s Q1 2026 results. The complaint, Yappi v. Wix.com Ltd., et al., No. 26-cv-08852, seeks to represent investors who acquired Wix securities between Feb. 19, 2025, and May 12, 2026. Hagens Berman alleges Wix made false or misleading statements about the competitiveness, performance and costs of its AI products, Base44 and Harmony, as the company responded to vibe coding (building software through plain-language AI instructions). The firm says Wix’s non-GAAP sales and marketing expenses reached $190.7 million, up 88% year over year, while its non-GAAP operating margin fell from 21% to 5% and quarterly operating expenses increased 46%. Wix’s market capitalization fell by more than $1.1 billion on May 13, 2026, after management acknowledged product gaps, delayed updates and customer use of competing AI tools. Hagens Berman is urging investors with significant losses to contact the firm before the Sept. 22, 2026, lead-plaintiff deadline and is investigating whether Wix intentionally understated the impact of its AI initiatives on operating results.
