Executive Summary

Three OMER insiders (VP/General Counsel, Director, VP Finance) sold a combined ~$578K in open-market shares over a week, with most sales coinciding with option exercises. At 0.04% of the $1.4B market cap, the cluster is trivial and likely reflects routine tax-motivated or diversification selling, not a bearish signal.
