Sonder, a short-term rental operator, has not filed its financial results for Q4 and the full year 2023, resulting in the Nasdaq issuing a deficiency notification. Furthermore, the firm became the object of a class-action investigation by the Rosen Law Firm, due to potential misleading business information delivery.

The Nasdaq warning, issued on April 2, indicates a violation of its rule demanding Nasdaq-listed companies file all periodic reports on time with the US Securities and Exchange Commission. To regain compliance, Sonder has 60 days from receiving the notice to submit a plan.

From a financial perspective, an accounting error related to the valuation and impairment of operating lease right of use assets for fiscal years 2022 and 2023 was previously announced by the company.
