Zhang Shuo 4

What Happened
Zhang Shuo, a director of PDF Solutions, received an award of 2,689 restricted stock units (RSUs) on 2026-07-01 (transaction code A — Award/Grant). No purchase price or immediate cash value is reported (price listed as N/A); the RSUs convert to common shares only as they vest.

Key Details

• Transaction date: 2026-07-01 (Form 4 filed 2026-07-02; appears timely).
• Transaction type: Award/Grant (code A). Quantity: 2,689 RSUs. Price: N/A.
• Shares owned after the transaction: not reported in the provided filing.
• Vesting: RSUs vest in four equal installments (25% each) on the first day of each calendar quarter following the grant effective date, subject to continued service (see footnote).
• No 10b5-1 plan, tax-withholding sale, or immediate sale noted in the filing.

Context
RSUs are a form of equity compensation that only become actual shares (and taxable) as they vest; this grant is not an immediate purchase or sale and doesn’t by itself indicate the director’s market view. For retail investors, grants are routine compensation for directors and should be viewed as part of long-term alignment rather than a near-term trading signal.
