Middleton (CFO/Executive VP/See Remarks) made a large open market purchase on June 9, 2025, buying 650,000 shares for an estimated \$672,035. He also purchased 350,000 shares on May 16, 2025. * Non-Open Market Acquisitions (Grants): * Several directors and officers received shares through Acquisition (Non Open Market) or Grant transactions, particularly around October 2025 and July 2025. These acquisitions are often compensation-related and not necessarily a direct investment decision like an open market buy.Sales * Sales Activity: * Benjamin Haycraft (CSO & EVP of EMEA Region) had a sale of 10,972 shares in September 2025. * George C. McNamee (Director) made sales of 10,000 shares each in November 2024, August 2024, and May 2024. * The largest sale in the last year mentioned was by the former Executive VP & GM of Material Handling, Jose Crespo, for shares worth about US$230k in October 2023 (though this is slightly over 12 months from the current date).Important Note: Insider trading data is derived from required filings with the U.S. Securities and Exchange Commission (SEC) on Form 4. While an open market purchase or sale can indicate management's confidence (or lack thereof), many transactions, especially "Acquisition (Non Open Market)" or "Grant" transactions, are non-discretionary and relate to compensation plans. Investors should review the specific SEC filings (Form 4) for the full context of any transaction.Would you like me to look for any other specific insider trading details, such as transactions by a particular executive?
