Nias James 4

What Happened
James Nias, Chief Accounting Officer of nLight, sold a total of 3,052 shares in two open-market transactions to cover tax withholding tied to vested restricted stock units. On May 15, 2026 he sold 1,487 shares at $75.16 for $111,763, and on May 18, 2026 he sold 1,565 shares at $70.82 for $110,833 — total proceeds about $222,596. These were sales (not purchases) and were mandated as "sell-to-cover" to satisfy tax obligations, not discretionary trades.

• Notable footnotes: F1 — sales were sell-to-cover for tax withholding (mandated by issuer); F2/F4 — weighted average prices per sale provided; F5 — filing notes shares from the ESPP purchase period (Nov 16, 2025–May 15, 2026) purchased at 85% of the Nov 17, 2025 closing price are included in holdings.
• Filing timeliness: Form 4 filed May 19, 2026; this appears timely (within the required two business days of the May 15/18 transactions).

Context
These were routine sell-to-cover transactions associated with RSU vesting and tax withholding — common and generally not interpreted as a sign of changed insider conviction. The filing also references ESPP purchases that increased holdings; no option exercises or discretionary open-market purchases were reported.
