Nierenberg Investment Management Company, Inc.

Nierenberg Investment Management Company, Inc. is a declared insider at 8 companies; the most frequent names are Electro Scientific Industries Inc, Asset Acceptance Capital Corp and Natus Medical Inc. Between 1 December 2009 and 7 August 2024, the trades on record add up to 206 filings.

The open-market side counts 14 purchases for €1.1M alongside 118 sales for €81.6M. Taken together, the sales exceed the purchases by €80.4M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 51 share grants and 16 option exercises. Since January 2024: 9 purchases and no sales on the market.

A typical purchase (the median) is worth €30k. Across 9 purchases, this insider has always bought alone, with no colleague buying within 30 days.

On 7 August 2024 came the latest disclosure, an open-market purchase for €150k in Potbelly Corp. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
