PDF Solutions, Inc. (PDFS) – Form 4 insider filing

Chief Technology Officer Andrzej Strojwas reported an internal share transaction dated 01 July 2025. The filing shows a disposition of 2,497 common shares at a price of $21.87 each, coded “F,” which indicates the shares were automatically surrendered to the company solely to cover federal and state tax-withholding obligations triggered by the vesting of restricted stock units (RSUs). No shares were sold into the open market.

Following the withholding transaction, Strojwas’ direct ownership stands at 83,613 common shares. This figure already includes 479 shares purchased on 31 Jan 2025 under the company’s Employee Stock Purchase Plan. No derivative securities were involved or reported.

The transaction is routine, does not signal a discretionary sale, and does not materially change insider ownership levels or imply a change in strategic outlook.

PDF Solutions, Inc. (PDFS) – Comunicazione interna Modulo 4

Il Chief Technology Officer Andrzej Strojwas ha segnalato una transazione interna di azioni datata 01 luglio 2025. Il documento indica una cessione di 2.497 azioni ordinarie al prezzo di 21,87 $ ciascuna, codificata come “F”, che significa che le azioni sono state automaticamente consegnate all’azienda esclusivamente per coprire le obbligazioni fiscali di ritenuta federali e statali generate dal consolidamento delle Restricted Stock Units (RSU). Nessuna azione è stata venduta sul mercato aperto.

Dopo questa operazione di ritenuta, la proprietà diretta di Strojwas ammonta a 83.613 azioni ordinarie. Questa cifra include già 479 azioni acquistate il 31 gennaio 2025 tramite il Piano di Acquisto Azionario per Dipendenti dell’azienda. Non sono stati coinvolti o segnalati strumenti derivati.

La transazione è di routine, non rappresenta una vendita discrezionale e non modifica in modo significativo i livelli di proprietà interna né implica un cambiamento nella strategia aziendale.

Positive
  • None.
Negative
  • Minor share dilution: 2,497 shares were returned to the company treasury, marginally increasing outstanding shares and causing a negligible bookkeeping dilution.

Insights

TL;DR: Routine tax-related share surrender; neutral impact on PDFS valuation.

The “F” code confirms shares were withheld to settle RSU taxes, a common administrative event that does not reflect insider sentiment or market sale pressure. Post-transaction ownership remains sizeable (≈83.6 k shares), suggesting continued alignment with shareholders. Given the small volume (≈3% of his holdings and immaterial relative to PDFS’s average daily volume), the event is non-material for valuation or liquidity considerations.
