NOGLOWS WILLIAM P 4

What Happened

• William P. Noglows, a director of Littelfuse, exercised stock options to acquire 911 shares on February 4, 2026. He paid $199.24 per share, for a cash outlay of about $181,508. The filing shows the option/derivative converted into common shares (no sale of shares reported).

Key Details

• Transaction date: 2026-02-04; Filing date: 2026-02-06 (timely filing).
• Transaction type/codes: M = exercise/conversion of derivative. One line shows 911 shares acquired at $199.24 ($181,508); a second line shows the derivative conversion (911 shares disposed at $0), which is SEC reporting convention for option conversion, not a market sale.
• Shares owned after transaction: Not specified in this Form 4 (not disclosed in the filing).
• Footnotes of note:
  • F1/F2: Some shares are held in trusts for the benefit of his son and daughter.
  • F3: The option for these 911 shares vested in thirds annually beginning April 26, 2019.
• No 10b5-1 plan, tax‑withholding sale, or open‑market sale was indicated in the filing.

Context

• This was an exercise of vested options, not a sale of shares to the open market. Exercising options is a way for insiders to convert vested option rights into stock by paying the strike price; it does not by itself signal buying or selling pressure unless shares are then sold.
• Because the filing was made two days after the transaction, it appears timely and routine. The trusts noted in footnotes indicate some shares are held for family beneficiaries, which is a common estate‑planning arrangement and not a market transaction.
