Key Details

• Transaction date: May 26, 2026; Form 4 filed May 28, 2026 (timely filing).
• Total shares sold: 13,809; total proceeds: approximately $2,141,004.
• Price details: the filing reports weighted-average prices for three lots with specified price ranges (see above); one lot shows a single price.
• Notable footnote: Sales were made pursuant to a Rule 10b5-1 trading plan adopted by Ullal on November 14, 2025.
• Ownership after transaction: The Form 4 does not specify the total shares beneficially owned by the reporting person after these sales.
• Other footnotes indicate certain shares are held in family trusts for which Ullal serves as trustee/co-trustee and that she disclaims beneficial ownership of those trust-held shares.

Context

These sales were executed under a pre-established 10b5-1 plan, which usually means the trades were planned in advance and are not ad hoc reactions to company news. For retail investors, selling by insiders is common for diversification or tax/liquidity needs and is less informative than insider buying when gauging management’s view of future prospects.
