McIntyre Pamela 4

What Happened

• Pamela McIntyre, Chief Accounting Officer of OneStream, was granted 45,000 restricted stock units (RSUs) on March 19, 2026. The reported acquisition price is $0.00, reflecting an equity award rather than a purchase. These RSUs are a contingent right to receive OneStream Class A common shares upon vesting.

Key Details

• Transaction date and type: 2026-03-19 — Award/Grant (code A).
• Shares/units granted: 45,000 RSUs; reported price $0.00 (no cash outlay).
• Vesting: RSUs vest as to 1/8th of the shares on each Quarterly Vesting Date (March 10, June 10, September 10, December 10) beginning June 10, 2026, subject to continued service. This implies full vesting over eight quarterly vesting events (approximately two years) if service continues. (Footnote F1)
• Reported shares include unvested RSUs. (Footnote F2)
• Shares owned after the transaction: not specified in the filing.
• Filing timeliness: Report covers 2026-03-19 and was filed 2026-03-20 — appears timely.

Context

• RSU grants are common employee compensation and do not represent an immediate market purchase or sale. They only convert into actual shares if and when the RSUs vest and any applicable conditions are met. This award does not by itself indicate an immediate change in insider buying/selling behavior.
