AOSL 10% Owner Mike Chang Receives RSUs; 14,419 Shares Withheld
What Happened
Mike F. Chang (reported as a 10% owner) was issued 22,500 restricted share units (RSUs) on March 16, 2026. To satisfy tax-withholding obligations when those RSUs vested, 14,419 shares were withheld (reported as a disposition) at $21.43 per share, totaling $308,999. The transaction report was amended to correct the number of shares withheld.
Key Details
- Transaction dates: 2026-03-16 (award and tax-withholding occurred same day).
- Award: 22,500 shares granted (code A) — reported acquisition at $0.00 (typical for RSU vesting).
- Withholding: 14,419 shares withheld to cover taxes (code F) at $21.43/share = $308,999 reported disposition.
- Net shares retained from the vesting: 22,500 − 14,419 = 8,081 shares (net delivered to insider).
- Shares owned after the transactions: not specified in the provided filing excerpt.
- Footnote: This is an amended Form 4 correcting an earlier reporting error in the number of shares withheld for taxes.
- Transaction types explained: A = award/grant (RSU vesting); F = shares withheld for tax withholding (not an open-market sale).
Context
This was an RSU vesting event with shares withheld to satisfy tax obligations — a routine administrative action rather than an intentional open-market sale or purchase. As a 10% owner, Chang’s filings are regulatory disclosures of beneficial ownership; withholding for taxes is common and does not by itself indicate a change in insider sentiment.
