Crum Brian T 4

What Happened

• Brian T. Crum, SVP, General Counsel & Secretary of Lexicon Pharmaceuticals (LXRX), had restricted stock units (RSUs) convert/vest into 273,006 shares on February 28, 2026 (reported as derivative exercise/conversion, code M).
• The company withheld 105,019 of those shares to satisfy tax withholding obligations (transaction coded F) at $1.47 per share, totaling approximately $154,378. After withholding, about 167,987 shares were delivered to Mr. Crum. The conversion entries show N/A for acquisition price because these were RSU conversions, not cash purchases.

Context

• This was a vesting/conversion of RSUs, not an open-market buy or sale. The withheld shares represent tax withholding (a common administrative step), not a market sale by the insider.
• Transaction codes: M = exercise/conversion of a derivative (here, RSUs converting to common stock); F = payment/withholding to cover taxes.
• For retail investors: RSU vesting is routine compensation-related activity and does not necessarily signal a personal buy/sell decision about the company's outlook.
