Lima Peralta Maria Alicia 4

What Happened
Maria Alicia Lima Peralta, Chief Legal Officer of Companhia de Saneamento Básico do Estado de Sao Paulo (Sabesp, ticker SBSP3), had 6,039 restricted stock units (RSUs) convert to common shares upon vesting on May 1, 2026. The RSU conversion shows an acquisition at $0 (no exercise price). To cover tax liabilities, 1,661 of those shares were surrendered/withheld at an effective price of $6.69 per share, totaling $11,112. The filing records the RSU conversion (derivative code M) and the tax withholding (code F).

Key Details

• Transaction date: 2026-05-01; Form 4 filed 2026-05-15 (filing reflects foreign private issuer reporting).
• Acquired: 6,039 shares via RSU conversion (exercise/conversion, code M) at $0.00.
• Withheld/Disposed for taxes: 1,661 shares at $6.69 each = $11,112 (code F).
• Footnote: On April 29, 2025 the reporting person was granted 24,142 RSUs vesting pro rata on May 1 of 2026–2029 (each RSU converts to one common share upon vesting).
• Filing remarks note adjustments for dividend equivalents, a March 2026 capital increase, and an April 2026 stock split.
• The issuer is a foreign private issuer (Rule 3a12-3(b)), and the filing states transactions are exempt from Sections 16(b) and 16(c) of the Exchange Act.
• Shares owned after the transaction: not specified in this Form 4.

Context

• This was a vesting of RSUs, not an open-market purchase or sale. The withholding of shares to pay taxes is a routine, administrative event (common with award vesting) and does not necessarily indicate a buy/sell sentiment.
• The $0 exercise price reflects conversion of RSUs (no cash paid to acquire the vested shares). The partial disposition represents a cashless tax withholding.
