Kim Peter Sung-Jip 4

What Happened

• Kim Peter Sung-Jip, SVP & GM, Industrial Business at Littelfuse, exercised options for 5,488 shares (code M) on Feb 2, 2026 at an exercise price of $166.63 per share (total cost $914,465) and then sold 5,488 shares in multiple open-market transactions (code S) the same day for aggregate proceeds of $1,790,984.

Context

• This appears to be a cashless exercise: options were exercised and the resulting shares were immediately sold. Transaction codes: M = exercise/conversion of derivative; S = open-market sale.
• Sales by insiders are often routine (liquidity or tax-related). Purchases typically convey a clearer positive signal; this filing documents an exercise followed by sales and is informational rather than an explicit endorsement of share direction.
