Alpern, Vice President and General Counsel of Arteris, exercised 5,000 derivative shares at $0.56 ($2,800 cash cost) and, on the same day (2026-02-02), sold 5,000 Arteris shares in the open market for a weighted average price of $15.48, generating approximately $77,377.

Key Details

• Transaction date: February 2, 2026 (Form 4 filed February 4, 2026 — timely filing)
• Exercise: 5,000 shares at $0.56 = $2,800 (code M — exercised/conversion)
• Sale: 5,000 shares sold at weighted avg $15.48 ≈ $77,377 (code S). Price range per footnote: $15.05–$15.93.
• Additional derivative line: 5,000 shares reported disposed at $0.00 (code M) — reflects conversion/settlement of a derivative instrument as reported; no cash proceeds shown on that line.
• Plan/footnotes: Sale made pursuant to a 10b5-1 trading plan adopted June 5, 2025 (F1). Weighted-average sale price reported; seller can provide per-lot prices on request (F2). Vesting history for these derivative awards: 25% vested Aug 26, 2020, then monthly vesting thereafter per footnote (F3).

Context

• The sequence (exercise and same-day sale) is a common pattern where vested options/derivatives are converted to shares and those shares are sold; this is effectively a cashless exercise/sale. Because the sale was made under a 10b5-1 plan, the trades were pre-arranged and not necessarily active, ad-hoc insider selling. This transaction is factual reporting of insider activity and does not, by itself, indicate company performance or insider motivations.
