The filing adds to a run of disclosed insider activity across Medtronic's executive ranks over the prior year. President Harry Skip Kiil reported five open-market sale lines dated February 19, 2026, together worth about $5.13 million at prices between $97.66 and $97.86; those sales were disclosed in a Form 4 filed February 26, 2026, seven days after the trade date. Kiil also reported two sale lines dated September 3, 2025, worth roughly $788,000 near $91.58. Vice President Gregory L Smith reported seven sale lines dated November 19, 2025, totaling about $3.06 million at prices near $102, disclosed November 21, 2025. On the buy side, Director William R Jellison reported two open-market purchases in late August 2025: 2,500 shares at $92.73 on August 22 and 2,500 shares at $92.37 on August 25, a combined value of about $462,750, both disclosed August 25, 2025.
Congressional STOCK Act disclosures also list $MDT activity in 2026. Representative Kevin Hern reported a sale dated August 24, 2026 and disclosed September 1, with a midpoint value of $15,001. Representative Richard Dean Dr Mccormick reported a sale dated July 30, 2026, with a midpoint value of $1,001. Representative Ro Khanna reported multiple $MDT purchases and sales during 2026, and Representative Gilbert Cisneros reported a sale dated May 15, 2026. Those congressional dollar figures are midpoint estimates of the bracketed ranges disclosed in the filings, not exact transaction values.
Medtronic plc operates in the health care sector and carried a market capitalization of about $113.18 billion in the database. The October filing left Marinaro with a six-figure share position in the company, and no other Medtronic insider reported a transaction on October 15 in the database. Across the $MDT Form 4 records in the database, the disclosed activity consisted of sales along with the two August 2025 purchases by Jellison.
