Key Details

• Transaction date: 2026-06-04; Form 4 filed: 2026-06-09 (filed 5 days after the transaction; later than the SEC’s typical 2-business-day reporting window).
• Grant: 10,957 RSUs (acquisition code A), reported price $0, reported value $0.
• Vesting: 100% vests on the earlier of (i) the next annual stockholder meeting or (ii) one year from the Vesting Commencement Date, subject to Hilleman’s continued service as a director (per footnotes).
• Shares issuable: Footnotes confirm 10,957 shares will be issuable upon settlement of the RSUs.
• Shares owned after transaction: Not specified in the filing.
• No 10b5-1 plan, tax-withholding sale, or immediate sale of underlying shares is indicated in the filing.

Context This was a compensation award (RSUs) to a director rather than an open-market purchase or sale. RSUs have no upfront cash cost to the recipient; their eventual value depends on SI-BONE’s stock price when the units vest and are settled. The filing was submitted after the usual 2-business-day window, which is noted by investors but does not by itself indicate trading intent.
