The Globe and Mail reports in its Friday, April 3, edition that insiders buying a stock is often a bullish sign. The Globe's guest columnist Ted Dixon says he is keeping a close eye on what insiders are doing with their own money during the Iran war. Tantalus Systems Holdings offers smart devices and analytics to modernize electrical-distribution grids, benefiting from the North American grid's development. For 2025, Tantalus delivered record revenue, up 22 per cent year-over-year, and record adjusted EBITDA, representing 156-per-cent growth from the prior year. It added 17 new utility customers during the year, while annual recurring revenue grew 14 per cent to $14.5-million. Three Tantalus insiders spent a total of $41,538 buying 9,300 shares at an average price of $4.47 after the release of 2025 results on March 18. The buying took place as the stock has been more or less flat over the past three months. Although the total is relatively modest, it is also worth noting that the stock has more than doubled over the past year. Consequently, it is encouraging to see insider buying as Tantalus stock consolidates rather than insiders taking money off the table.
