SI-BONE, Inc. (SIBN) – Form 4 filing dated 07/07/2025

Senior Vice President, Operations & Administration and Chief Legal Officer Michael A. Pisetsky reported a routine “sell-to-cover” transaction tied to the vesting of restricted stock units (RSUs) on 07/02/2025. To satisfy withholding taxes, Pisetsky sold an aggregate 3,127 common shares in three market transactions at weighted-average prices between $18.26 – $18.38 per share.

Following the sales, the executive retains 261,681 common shares, which includes 145,043 shares underlying un-settled RSUs. No derivative securities were involved, and the filing states the sales were non-discretionary and solely for tax purposes.

The disposition represents approximately 1.2 % of the executive’s post-transaction holdings and does not alter overall insider ownership meaningfully. There is no indication of strategic intent or change in outlook for SIBN; the filing is considered administratively routine under Section 16 rules.

매도 후, 해당 임원은 261,681 보통주를 보유 중이며, 이 중에는 미결제 RSU에 해당하는 145,043주가 포함되어 있습니다. 파생 증권은 포함되지 않았으며, 제출 서류에는 매도가 비재량적이고 세금 목적만을 위한 것임이 명시되어 있습니다.

이번 처분은 임원의 거래 후 보유 주식의 약 1.2%에 해당하며, 내부자 지분에 큰 변화를 주지 않습니다. SIBN에 대한 전략적 의도나 전망 변화의 징후는 없습니다; 이 제출은 섹션 16 규정에 따른 행정적 일상 절차로 간주됩니다.

Insights

TL;DR: Routine sell-to-cover of 3,127 shares; negligible impact on SIBN outlook.

The Form 4 shows a standard tax-withholding sale by SVP & CLO Michael Pisetsky. Post-sale ownership remains high at 261,681 shares (≈145 k RSUs pending). The 3,127-share disposition equals roughly one trading day’s volume (<1 % float impact) and just 1.2 % of the insider’s stake. Because the transaction is nondiscretionary and required by RSU vesting, it does not imply bearish sentiment. Consequently, the filing is neutral for valuation and sentiment purposes.
