Jacquemet Cyrille 4

What Happened
Cyrille Jacquemet, Chief Revenue Officer of Ouster, sold 10,000 shares of Ouster common stock on May 14, 2026, at $35.00 per share for proceeds of $350,000. The sale was reported on a Form 4 filed May 21, 2026.

Key Details

• Transaction date and price: May 14, 2026 — 10,000 shares sold at $35.00 each (total $350,000).
• Footnote F1: The sale was made pursuant to a Rule 10b5-1 trading plan dated June 13, 2025 (a pre‑arranged trading plan).
• Footnote F2: The filing also notes 616 shares were acquired by the reporting person on May 15, 2026 under the company’s 2022 Employee Stock Purchase Plan.
• Shares owned after transaction: Not specified in the provided excerpt of the filing.
• Timeliness: The Form 4 was filed May 21, 2026 for a May 14 transaction — this is beyond the standard 2-business-day SEC filing window and therefore appears late.

Context

• A sale under a 10b5-1 plan is a pre-arranged transaction designed to provide an affirmative defense against claims of trading on material nonpublic information; such sales are often routine and not necessarily a statement about the insider’s view of the company.
• For retail investors, purchases are generally more informative than routine sales; this filing documents a planned disposition rather than an opportunistic buy.
