Summy Amy B., EVP and Chief Marketing Officer, has demonstrated a consistent pattern of selling activity in her transactions involving Laboratory Corporation of America Holdings (LH), as disclosed in SEC Form 4 filings. Over 34 reported trades, Summy has exclusively sold shares, with no recorded purchases, resulting in total proceeds of approximately $2.3 million. Her recent activity includes three significant sales in 2026, with the largest transaction occurring on March 26, 2026, valued at $492,745.68. This follows a series of smaller sales earlier in the year, such as $21,920.80 on February 9, 2026, and $25,502.40 on February 6, 2026. The trend extends back to 2024, with notable transactions including a $760,515 sale on April 1, 2024, and a $468,224.34 sale on March 27, 2024. Summy’s trading history reveals a focus on LH, the sole company in her portfolio, and a clear preference for divesting shares rather than acquiring them. While the filings indicate occasional acquisitions of shares through non-open market transactions (coded as “A”), these are accompanied by no reported monetary value, suggesting they may be related to equity awards or other compensatory mechanisms. Summy’s consistent selling activity highlights a strategic reduction in her holdings of LH shares over time.
