Donal L. Mulligan

Donal L. Mulligan is a declared insider at 3 companies (board member); the most frequent names are Tennant Co, Herbalife Ltd. and Energizer Holdings, Inc. Over a trading history stretching from 6 May 2021 to 12 August 2026, the count stands at 25 filings.

Every open-market trade on record is a purchase: 7 purchases worth €2.0M, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 10 share grants and 8 option exercises. 2026 to date brings 2 purchases and no sales.

A typical purchase (the median) is worth €270k. On 5 out of 7 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The newest entry dates from 13 August 2026: an open-market purchase of €467k, in Tennant Co. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
