FibroGen, Inc. (NASDAQ: FGEN)

Class Period: November 8, 2019 to April 6, 2021

Lead Plaintiff Deadline: June 11, 2021

On August 18, 2019, the Company issued a press release announcing, "Positive Phase 3 Pooled Roxadustat Safety and Efficacy Results" and that shortly thereafter on December 23, 2019, FibroGen announced that it had submitted a New Drug Application to the Food and Drug Administration for roxadustat.

On April 6, 2021, the Company revealed that its previously disclosed safety data included undisclosed post-hoc changes to the stratification factors and did not include analyses based on the pre-specified stratification factors. As a result of these changes, FibroGen was forced to concede that roxadustat, contrary to prior representations, did not reduce the risk of cardiovascular events or hospitalization as compared to a currently approved anemia injection used as a control based on pre-specified stratification factors.

On this news, the Company's share price fell $14.90, or 43%, to close at $19.74 per share on April 7, 2021.

The complaint, filed on April 12, 2021, alleges that defendants failed to disclose to investors: (i) that the Company's prior disclosures of U.S. primary cardiovascular safety analyses from the roxadustat Phase 3 program for the treatment of anemia of CKD included post-hoc changes to the stratification factors; (ii) that FibroGen's analyses with the pre-specified stratification factors result in higher hazard ratios (point estimates of relative risk) and 95% confidence intervals; (iii) that, based on these analyses, the Company could not conclude that roxadustat reduces the risk of (or is superior to) MACE+ in dialysis, and MACE and MACE+ in incident dialysis compared to epoetin-alfa; (iv) that, as a result, the Company faced significant uncertainty that its NDA for roxadustat as a treatment for anemia of CKD would be approved by the FDA; and (v) that, as a result of the foregoing, defendants' statements about the Company's business, operations and prospects were materially misleading and/or lacked a reasonable basis.

Canaan, Inc. (NASDAQ: CAN)

Class Period: February 10, 2021 to April 9, 2021

Lead Plaintiff Deadline: June 14, 2021

Canaan designs, manufactures and sells bitcoin mining machines, primarily in the Peoples Republic of China (the "PRC"). It is organized under the laws of the Cayman Islands, headquartered in Hangzhon PRC and its ADRs are listed and trade on the NASDAQ Global Market.

On Monday, April 12, 2021, Canaan issued a press release finally disclosing its actual 4Q20 and FY20 financial results for the period ended December 31, 2020, including a 93% year-over-year decrease in computing power sold and net revenues for the quarter.

On this news, the market price of Canaan ADRs collapsed from their close of $18.67 per ADR on April 9, 2021 to close at $13.14 per ADR on April 12, 2021, a decline of nearly 30%.

The complaint, filed on April 15, 2021, alleges that the statements Canaan issued during the Class Period about the Company's business metrics and financial prospects were materially false and misleading in that they concealed that due to ongoing supply chain disruptions and the introduction of the Company's next-generation A12 series bitcoin mining machines – which had cannibalized sales of the older product offerings – Canaan's 4Q20 sales had declined more than 93% year-over-year compared to its fourth quarter fiscal year 2019 ("4Q19") sales and more than 93% quarter-over-quarter compared to its third quarter FY20 ("3Q20") sales. As a result, Canaan's 4Q20 total net revenues had decreased to RMB38.2 million (US$5.9 million) from RMB463.2 million in the 4Q19 and RMB163.0 million in the 3Q20.

Credit Suisse Group AG (NYSE: CS)

Class Period: October 29, 2020 to March 31, 2021

Lead Plaintiff Deadline: June 15, 2021

The complaint, filed on April 16, 2021, alleges that during the Class Period defendants issued materially false and misleading statements regarding the Company's business metrics and financial prospects. Specifically, defendants concealed material defects in the Company's risk policies and procedures and compliance oversight functions and efforts to allow high-risk clients to take on excessive leverage, including Greensill Capital ("Greensill") and Archegos Capital Management ("Archegos"), exposing the Company to billions of dollars in losses.

As a result of defendants' false statements, Credit Suisse ADRs traded at artificially inflated prices, reaching a high of $14.95 per ADR by February 2021.

Subsequently, Credit Suisse revealed billions of dollars in losses tied to the collapse of its Greensill-linked funds and the implosion of total return swap positions Credit Suisse had entered into with Archegos.

These corporate scandals have revealed grave deficiencies in Credit Suisse's risk and compliance activities, causing the price of Credit Suisse ADRs to plummet, reaching a low of just $10.60 per ADR by March 31, 2021.
