Herr Amy E. 4

What Happened

• Amy E. Herr, a director of Bio-Techne Corp (TECH), executed derivative transactions on 2026-02-03. She exercised/converted a derivative position that resulted in 38 shares acquired at $0.00 and also had 38 derivative shares disposed (conversion/settlement). Separately, 16 shares were disposed to satisfy a tax liability at $64.63 per share, generating $1,034 in withholding. Overall, the transactions result in a net decline of 16 shares held by Herr (38 acquired − 38 disposed − 16 withheld = −16).

  • F (payment of exercise price/tax withholding): 16 shares disposed @ $64.63 = $1,034.
  • M (exercise/conversion – recorded as disposed): 38 shares disposed @ $0.00.

• Footnotes/notes: the F-coded disposition reflects tax withholding to satisfy withholding obligations. The filing includes multiple footnotes about vesting schedules for awards and options (see the filing for details).

Context

• The pattern (exercise/conversion combined with a small number of shares withheld/surrendered) is typical of option/RSU vesting or conversion where shares are used to cover taxes rather than a market-directed sale. The cash proceeds reported were $1,034 from the 16-share tax withholding. These transactions are usually routine compensation-related actions and should not be interpreted as a market timing signal.
