Key Details

• Transaction date and price: May 11, 2026 — 660,233 shares at $19.69 each; total value $12,999,988.
• How shares were acquired: Purchased through the company’s at-the-market (ATM) equity offering program (per footnotes), at the prevailing market bid price or better.
• Filing status: Amended Form 4 filed May 15, 2026 reporting the May 11 transaction.
• Entity holdings: Some reported shares are held via entities (Genius 24C Inc. and Blazon Corporation) for which the reporting person is sole shareholder (per footnotes).
• Other notes: Footnotes state the purchases occurred during an open trading window and reference ~700 shares inadvertently not reported in a Schedule 14A filing.

Context

• As a 10% owner (not a routine employee trade), this is a large-owner purchase reported directly by the beneficial owner. The acquisition was executed through the company’s ATM program (sales agent: TD Securities (USA) LLC), meaning shares were bought in the open market under the ATM offering rather than via a private transfer or option exercise.
