MADDOCK ERNEST E 4

What Happened Ernest E. Maddock, a director of Ouster, Inc. (OUST), received a grant of 4,725 restricted stock units (RSUs) on June 17, 2026. The RSUs were issued at $0.00 (no cash paid) and represent a contingent right to receive one share of Ouster common stock per RSU when vested. This is an equity award (compensation) rather than a purchase or sale of shares.

Key Details

• Transaction date: 2026-06-17 (Grant / Code A)
• Amount: 4,725 RSUs; acquisition price reported as $0.00
• Filing date: 2026-06-22 (filed five days after the transaction; this appears to be later than the typical 2-business-day Form 4 reporting requirement)
• Shares owned after transaction: not specified in the provided excerpt of the filing
• Footnote: RSUs vest in quarterly installments through the earlier of June 17, 2027 or the Company’s next annual meeting, subject to continued service

Context RSUs are a common form of director compensation and do not represent immediately tradable shares until they vest (and may be subject to tax withholding at vesting). Because this was an award rather than an open-market purchase or sale, it should be viewed as routine compensation, not a direct market vote by the insider.
