Gephart Brian 4

What Happened

• Brian Gephart, Chief Accounting Officer of Magnite, disposed of 3,789 shares on May 15, 2026 as payment for tax withholding obligations tied to vested restricted stock units. The shares were recorded at $12.82 each, totaling approximately $48,575.
• This was a non-discretionary forfeiture (tax withholding), not an open-market sale or a purchase — a routine administrative action when RSUs vest.

Context

• Tax-withholding forfeitures on RSU vesting are routine and administrative; they do not necessarily indicate the insider's view on the company's prospects.
• Because this was a withholding-for-taxes event (not an open-market sale), it should be interpreted differently than voluntary stock sales or purchases.
