John McEwen

John McEwen is a declared insider of Tantalus Systems Holding Inc. (formerly RiseTech Capital Corp.), with filings sourced from SEDI. The record holds 6 filings, for trades running from 23 May 2024 to 8 August 2026.

The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The record was last updated on 13 August 2026 with an option exercise (€1,708) in Tantalus Systems Holding Inc. (formerly RiseTech Capital Corp.). Filings reach the SEDI feed a median of 5 days 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.
