Dr Hal Barron

Dr Hal Barron discloses dealings in GSK plc to RNS (LSE). The record holds 66 filings, for trades running from 20 June 2023 to 10 July 2026.

On the open market, the record shows 12 purchases worth €118k and 4 sales worth €3.4M. The amount is not disclosed for 3 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 50 share grants.

In size, the median ticket on the buying side is €11k. On 11 out of 11 purchases, another insider of the same company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

Most recently, on 17 July 2026, the filings show a share grant worth €1,731 in GSK plc. The latest purchase dates back some time: it was published 390 days ago, on 22 September 2025. Between a trade and the moment it shows up on RNS (LSE), the median delay is 3 days. The legal deadline for notifying a trade is three business days (UK MAR). Every figure here comes from the filings published by RNS (LSE) and describes the past, not future prices; it is not investment advice.
