Kara Swisher reports[1] that his intent in selling stock was to raise money to donate to medical research:

There was, in fact, a question at a recent “tea time” — bi-weekly employee meetings with top execs — about Rowghani’s large sale of his shares. Those in attendance told me that Rowghani got up and told the audience that he was not thrilled to answer the question, but noted that he wanted the money to give to research to battle a disease that took his father’s life. It was an emotional address, said those present.
