Adrangi's hedge fund Kerrisdale Capital published a research paper that suggests Qualcomm's profits could be at risk as the company faces lawsuits, especially one in the United States.
If the company loses to the U.S. Federal Trade Commission, Kerrisdale said that Qualcomm would be forced to "license core patents to competitors and to renegotiate all of its existing licenses on fair terms."
That would create a "period of immense confusion and uncertainty about Qualcomm’s prospects - and ... could realistically cut Qualcomm's licensing revenue, earnings power, and stock price in half," the report says.
The Federal Trade Commission filed its case in the U.S. District Court for the Northern District of California and is alleging that Qualcomm's patent licensing and chip sale practices were anticompetitive and sought to preserve a monopoly on so-called premium LTE modem chips, which help mobile phones connect to wireless data network.
"In the past Qualcomm has been able to keep its business model going, but this time the threats are far more severe," Adrangi said. Previous legal troubles cost the company money.
A judgment against the company in this case could force an overhaul of its business model, the hedge fund argues. "As Qualcomm’s long-running game of monopoly draws to a close, there will be no 'Get Out of Jail Free' card," the report said.
Kerrisdale is arguing that Judge Lucy Koh, who is presiding over the case, has already ruled against the company on several matters and may be inclined to rule for the FTC.
Qualcomm's stock traded at $54.16 on Tuesday and Kerrisdale sees a chance for it to fall by half in the next year or two.
The company has a market capitalization of $66 billion and its stock is owned by mutual fund companies such as Vanguard and Fidelity.
Kerrisdale is a New York- based hedge fund managing roughly $150 million in assets. But it has taken on big targets before, including satellite communications company Globalstar. It has a large social media presence and boasts a 37 percent gain in 2018, far better than the average hedge fund which lost roughly 4.5 percent.
