David Wallace Cornhill discloses dealings in AltaGas Ltd. to SEDI. The record holds 8 filings, for trades running from 22 June 2026 to 16 October 2026.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The newest entry dates from 16 October 2026: an option exercise of €86k, in AltaGas Ltd. Filings reach the SEDI feed a median of 1 day after the trade. This delay matters because a trade only becomes useful information once it is public. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
