Billionaire activist Bill Ackman is staking his reputation on his latest Herbalife expose.
The Pershing Square founder, in a TV interview to promote his presentation on the multi-level marketing company set for Tuesday morning, said the event “will be the most important presentation I’ve made in my career.”
“You’re going to learn why Herbalife is going to collapse,” he said on CNBC, acknowledging that “I’m raising expectations, but we won’t disappoint.”
The market took him at his word, with shares of Herbalife falling more than 11 percent, or $6.82, to close at $54.02. The stock had already fallen 5 percent since last Wednesday, when The Post first reported the upcoming event.
After restructuring most of his short to options, Ackman stands to gain $2 billion if the company fails.
Ackman said the presentation is the culmination of a two-year investigation by his team, with videos and internal documents showing how Herbalife’s nutrition clubs perpetuate the alleged fraud.
He also said he will show Herbalife execs are involved in the fraud and not just the company’s independent distributors.
Nutrition clubs have been the biggest driver of the company’s growth over the past five years, according to Ackman.
On Friday, he upgraded the event from a webcast to a live event in midtown Manhattan.
Herbalife, the LA-based peddler of protein shakes and other weight loss products, denies it is a pyramid scheme and has been on a massive PR blitz since The Post reported the upcoming expose.
Its Twitter feed “HerbalifeTruth” calls Ackman “The worst of Wall Street.”
