Underberg Sharon E., EVP, GC & Corporate Secretary, has demonstrated a clear selling bias in her trading activity involving IDEXX Laboratories (IDXX), the sole company in her transaction history. Over 39 reported trades, her total sell value of $4,006,098 significantly outweighs her total buy value of $1,426,931. The most notable sale occurred on August 8, 2025, when she disposed of shares worth $3,551,220, followed by an acquisition of shares valued at $1,127,823 on the same day—likely reflecting a net reduction in position. More recently, her activity has leaned toward smaller transactions, including a $157,966 purchase on February 14, 2026, and a $99,589 sale on March 3, 2026.
Her trading pattern suggests a recurring cycle of stock awards and subsequent sales, with multiple transactions coded as "M" (market purchases) and "F" (tax withholdings) around mid-February each year—a timing often aligned with equity compensation vesting. Notably, several filings show zero-dollar transactions, likely representing stock awards or adjustments without immediate market activity. While her buys have been consistent in the low-to-mid six figures, the August 2025 sale stands out as a major liquidity event. The absence of recent buys beyond February 2026 further reinforces a trend toward gradual divestment rather than accumulation.
