This is just one example of warrants being issued at a high price:
“STONY BROOK, NY--(Marketwired - November 25, 2015) - Applied DNA Sciences, Inc. (NASDAQ: APDN) (Twitter: @APDN), a provider of DNA-based supply chain, authentication and product identification solutions, anti-counterfeiting and anti-theft technology, and product genotyping solutions, announced the closing of its registered direct offering pursuant to securities purchase agreements with certain institutional investors of 2,500,000 shares of common stock at a price of $3.49 per share and its concurrent private placement of warrants to purchase 1,250,000 shares of common stock at a price of $.01 per warrant. The warrants have a per share exercise price of $4.30, are exercisable beginning six months from the date hereof and will expire five years from the date on which they become exercisable.”
When you look at the above and compare to the Sabby deal in December 2017, it is rather shocking.
