GW Pharmaceuticals Accused of Failing to Implement Adequate Internal Controls

According to the complaint, GW Pharmaceuticals filed a Form 20-F and several Forms 6-K with the U.S. Securities and Exchange Commission in 2014 and 2015, attesting to the accuracy of the financial information and affirming that any material changes to the company’s internal controls over financial reporting were disclosed. However, the complaint alleges these statements were false because the company failed to disclose that it lacked effective internal financial controls, as well as effective controls over completeness and valuation of clinical trial accruals.

On December 7, 2015, GW Pharmaceuticals disclosed in its annual report for the fiscal year ended September 30, 2015, that its internal financial controls were not effective as of September 30, 2015. The company stated that if the statements were prepared improperly, it would be required to restate its financial statements, which could result in a loss of investor confidence and a decline in the price of its American Depository Shares. The Form further stated that it lacked sufficient controls to ensure completeness of clinical trial accruals in connection with contractual progress payment liabilities. Then, on January 10, 2016, an article in The Sunday Times disclosed that GW Pharmaceuticals’ management had determined that it lacked effective controls over the completeness and valuation of clinical trial accruals. On this news, GW Pharmaceuticals stock fell $3.55 per share, or nearly 6%, to close at $56.31 per share on January 11, 2016.

They’ve been listed on NASDQ for a couple of years so lots of public sec filings are available. Financially, they’re not in the best of shape and are  dependant on a product-limited propriety technology platform and appear to face challenges even in those countries where the drug they currently market is legal . e.g., they may not get benefit of coverage under government reimbursement programs.
They’re currently  running at a loss. It looks like their last fiscal year revenues were $43 million and lost $67 million due to high high R&D costs.  They’re having an investor call on the 2/10 to report on the quarter ending December 2015

Why GW Pharmaceuticals Shares Tumbled 25% in January
February 02, 2016, 10:00:11 AM EDT By Todd Campbell, The Motley Fool, Motley Fool CommentWhat: Following reports that the company’s financials may lack adequate accounting controls, shares in GW Pharmaceuticals, plc fell 25.3% in January, according to S&P Capital IQ .

So what: Early last month, the company disclosed that it has material weaknesses in its accounting practices related to clinical trial costs and milestones.

That’s concerning given that there’s tremendous trial activity occurring at the company.

GW Pharmaceuticals is one of the most committed drugmakers to the study of marijuana-derived medicine and its trials have included research into marijuana’s use in cancer pain, diabetes, schizophrenia, and epilepsy.

In December, the company reported that its R&D costs were $25.5 million in its fiscal fourth quarter, up 107% from last year.
