New options on MannKind available for July 25 expiration

Today, MannKind Corporation (NASDAQ:MNKD) shares opened at $10.09, a level not seen since March 19, 2010. The company still doesn’t generate revenues, but its Afrezza drug, if approved (which is highly likely), has the potential to generate more than $3.65 billion in annual sales by 2025. High expectations have given MannKind stock a valuation of close to $4 billion. Therefore, many investors remain cautious about the stock. Some others believe that the best way to play with MannKind is through options market. Yesterday, new options for MannKind became available, for the July 25th expiration.

Speaking at the Jefferies Global Healthcare Conference earlier this week, MannKind Corporation (NASDAQ:MNKD) CFO Matt Pfeffer discussed commercialization potential of Afrezza. He said the company’s Danbury facility has the capability to produce up to two billion insulin cartridges per year. The company hasn’t entirely built the facility before approval of the drug, so it will have to install equipment.
