Richard Bartram

Richard Bartram, listed as finance chief, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Esperion Therapeutics, Inc. and MBX Biosciences, Inc. In total, 8 filings cover trades dated from 2 January 2018 to 2 February 2026.

On the market, this insider has only sold: 2 sales, €305k in total. Besides market trades, the filings include 5 share grants and 1 option exercise.

The record was last updated on 3 February 2026 with a share grant in MBX Biosciences, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
