RE:CEO bought 100k - just filedI think the insider buy is more of a strategic nature than a minor addition to the millions of shares that he already owns for growing wealth.
According to the last NR there was meetings scheduled with the top-10 pharma company with the sole purpose to nail a deal. So when the CEO bought his 100K the negotiation meetings had begun.
Pure speculation, but I think that SBM has put forward pretty aggressive terms and the top-10 pharma tries to get away cheap. The negitiation can take a long time and it's important that SBM does not starve to death in the process. The warrants due mid October are key. Bottom line, I think the CEO is trying to support the share price in order to encourage the warrant holders to exercise.
