Brottem John L. 4

What Happened

• John L. Brottem, General Counsel of Outset Medical (OM), disposed of 2,638 shares of common stock on May 15, 2026 at $3.70 per share, generating $9,761 in proceeds.
• The sale was a "sell-to-cover" to satisfy tax-withholding obligations tied to the vesting of RSUs and is reported as a routine, non-discretionary transaction.

Key Details

• Transaction date and price: May 15, 2026 — 2,638 shares sold at $3.70/share (proceeds $9,761).
• Reason: Footnote F1 states the shares were sold to cover taxes on the vesting of an aggregate 5,033 RSU shares granted Jan 12, 2024 and Jun 10, 2025; not a discretionary sale.
• Reporting correction: Footnote F2 corrects a prior Form 4 (filed Feb 19, 2026) that misreported a separate withholding sale as 2,842 shares instead of the correct 2,862 shares.
• Shares owned after transaction: Not specified in the materials provided.
• Filing timeliness: Report filed May 19, 2026; this filing falls within the typical 2-business-day Form 4 deadline and is therefore timely.

Context

• Sell-to-cover transactions are common when equity awards vest and generally reflect tax-related mechanics rather than an insider signaling confidence or concern about the company.
• No purchase or options-exercise behavior is indicated here; the filing documents only the tax-withholding sale and a correction to a prior report.
