DE GREEF RODERICK 4

What Happened

• Roderick De Greef, President & CEO and Director of BioLife Solutions (BLFS), had 11,101 shares withheld by the company to satisfy tax withholding obligations that arose upon the release of restricted stock units (RSUs). The shares were valued at $19.12 each, for a total of $212,251. This was a withholding/disposition to cover taxes—not an open-market sale or purchase.

Key Details

• Transaction date: 2026-03-19
• Price per share: $19.12; Shares withheld/disposed: 11,101; Total value: $212,251
• Shares owned after transaction: Not specified in the provided filing excerpt
• Footnote: F1 — the shares were withheld by the issuer to satisfy the reporting person’s tax withholding obligations on RSU release
• Filing date: 2026-03-23 (Form 4 filed within the typical 2-business-day window for a 3/19 transaction)

Context

• This was a routine tax-withholding event tied to RSU vesting (a common "cashless" or share-surrender mechanism). It does not represent an open-market sale by the insider and should not be interpreted on its own as a directional signal about the executive’s view of the company.
