ON24 (ONTF) CFO Steven Vattuone Sells Shares in Merger Cash-Out

What Happened

Steven Vattuone, Chief Financial Officer of ON24 Inc., had a large disposition of common stock as part of the company's merger closing on April 1, 2026. The Form 4 shows 511,936 shares of common stock were disposed to the issuer and converted to cash under the merger, generating roughly $4,146,681.60 (511,936 × $8.10).
The filing also records an acquisition (award) of 79,935 shares at $0.00 and two derivative dispositions of 90,982 and 9,018 shares at $0.00. These entries reflect conversion/cancellation of equity awards and options as part of the Merger Agreement, not open-market trades.

Key Details

Transaction date: April 1, 2026; Form 4 filed April 2, 2026 (timely).
Cash consideration for common stock: $8.10 per share under the Merger Agreement.
Cash realized from the 511,936 common-share conversion: approximately $4,146,681.60.
Derivative dispositions (90,982 and 9,018) show $0.00 cash in the filing; per the Merger Agreement, options were converted into a cash amount equal to $8.10 less the option exercise price (zero if not in-the-money).
The 79,935-share acquisition is recorded at $0.00; footnote indicates RSUs received similar merger treatment and unvested RSUs may remain subject to vesting conditions.
Shares owned after the transactions are not specified in the Form 4.

Context

These were merger-driven conversions/cancellations — dispositions to the issuer — not voluntary open-market sales. That means the activity reflects the deal mechanics (cash-out at $8.10/share and option/RSU treatment) rather than a trading decision by the insider.
For options showing $0.00 cash, the merger formula can produce no payout when the exercise price is equal to or exceeds the merger price.
