Robert S. Herlin is Director at EVOLUTION PETROLEUM CORP (EPM). They have made 7 open-market trades across 3 companies since 2009, most recently 2025-12-04.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
2 open-market purchases totalling $26K since 2011, against 5 sales. Too few scored purchases to measure a record yet.
