WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience or resources. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 3 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020 founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs Bar. Many of the firms attorneys have been recognized by Lawdragon and Super Lawyers. DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (1) the Company would be unable to timely file its 2020 annual report due to delays related to the review of classification of certain costs and the recoverability of the right to use assets with certain leases; (2) the Company was reasonably likely to report material weaknesses in its internal control over financial reporting; and (3) as a result of the foregoing, defendants positive statements about the Companys business, operations, and prospects were materially misleading and/or lacked a reasonable basis. When the true details entered the market, the lawsuit claims that investors suffered damages.

You may also remain an absent class member and do nothing at this point. An investors ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
