According to the lawsuit, defendants during the Class Period made materially false and/or misleading statements and/or failed to disclose that: (1) Gridsum lacked effective internal control over financial reporting; (2) consequently, Gridsum’s financial statements were inaccurate and misleading, and did not fairly present, in all material respects, the financial condition and results of operations of the Company; and (3) as a result of the foregoing, Gridsum’s public statements were materially false and misleading at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.
