Portola Pharmaceuticals, Inc. (PTLA) Accused of Misleading Shareholders

According to the complaint, throughout the relevant period, Portola had issued a series of misleading statements that failed to disclose that Portola's internal control over financial reporting for reserve product returns was not effective. Specifically, the Company was shipping longer-dated product with 36-month shelf life without establishing adequate reserve for returns of prior shipments of short-dated product, which created a need for Portola to "catch up" on accounting for return reserves. As a result, on January 9, 2020, Portola announced preliminary net revenues of only $28 million for fourth quarter of 2019, citing a $5 million reserve adjustment for short-dated product and flat quarter-over-quarter demand for the disappointing financials. On this news, the Company's share price fell $9.98 per share, or approximately 40%, to close at $14.76. The stock continues to decline.
