Infinity Pharmaceuticals Inc. (NASDAQ:INFI)’s stock price had been doing quite well, having been up 35% year to date as of the beginning of April before plunging this month (likely due to these share sales). It is now up only 5% for 2012, but over 200% in the last year. As a development stage company, it only receives revenue in the form of collaborative research and development funds, a figure which declined last year compared to 2011. Almost $120 million was used on research and development for the year, which made up the overwhelming majority of Infinity Pharmaceuticals Inc. (NASDAQ:INFI)’s expenses. The company used $80 million in cash on operations in 2012, raising cash from the issuance of common stock. At the end of the year, Infinity had $180 million in cash and cash equivalents as well as $150 million in liquid securities, which should be sufficient to cover operations for at least some time. Analysts are not expecting the company to be profitable this year or next year.
