Does sam waltons grandaughter own 50 percent or more of Lowe's controllable shares?

As of my last knowledge update in October 2023, Sam Walton's granddaughter, Steuart Walton, does hold a significant stake in Walmart, but there is no public information indicating that she owns 50 percent or more of Lowe's controllable shares. Ownership stakes in publicly traded companies like Lowe's can change frequently, so for the most accurate and up-to-date information, it's best to consult recent financial disclosures or news articles.
