SBSP3 Corporate Services Officer Do Valle Fehlberg Gustavo Exercises RSUs
What Happened
Do Valle Fehlberg Gustavo, a Corporate Services Officer at Companhia de Saneamento Básico do Estado de São Paulo (Sabesp, ticker SBSP3), had 7,371 restricted stock units (RSUs) vest on May 1, 2026. The vesting resulted in the issuance/conversion of 7,371 underlying shares (exercise/conversion of a derivative, code M). To cover tax obligations, 2,027 of those shares were withheld/disposed (code F) at $6.69 per share, generating $13,561 in cash.
Key Details
- Transaction date: May 1, 2026; Form 4 filed May 15, 2026. No late-file flag is indicated on the filing itself.
- Actions reported: Exercise/conversion of derivative (M) = 7,371 shares issued; tax withholding (F) = 2,027 shares withheld/sold at $6.69, proceeds $13,561.
- Shares owned after the transaction: not reported on this Form 4.
- Footnote: These shares are the first pro rata tranche from a 29,486-RSU grant made April 29, 2025 (vesting annually on May 1 in 2026–2029). Each RSU converts to one common share upon vesting.
- Filing remarks: Amounts reflect recent issuer events exempt from Section 16(a) reporting (dividend equivalents, a March 2026 capital increase, and an April 2026 stock split). The issuer is a foreign private issuer, and the filing notes exemptions from Sections 16(b) and 16(c).
Context
- This was a standard RSU vesting event, not an open-market purchase or voluntary sale for investment signaling. The tax-withholding (F) is routine—shares were surrendered to satisfy withholding rather than a public sale.
- For retail investors: vesting/issuance increases the insider’s share count (net of withholding) but does not necessarily indicate a positive or negative view of the company.
