Executive Summary

A single large 10% owner, MegaChips Corp, sold $311.8M worth of SITM shares (~1.5% of market cap, a significant amount) in an open-market sale on May 14, 2026. This follows SITM's strong Q1 2026 earnings (revenue +88% YoY, non-GAAP EPS beat) reported on May 6. The insider cluster is a sell-only event by a strategic holder, not management, and its size relative to market cap is material.

Actionable Insight

A 10% owner selling ~1.5% of market cap post-earnings is a significant overhang. Monitor for further filings (Form 4 for additional sales, Schedule 13D amendment). The stock has rallied ~90% T+20 on prior neutral reports — this sale may indicate the large holder is taking profits at elevated levels. Watch for price support below the $779.50 trade price.

Key Facts

  • MegaChips Corp, a 10% owner, sold 400,000 shares on 2026-05-14 at $779.50/share for total proceeds of $311.8M.
  • The sale represents ~1.5% of SITM's $20.4B market cap, exceeding the 0.5-2% threshold for material insider selling.
  • Director Akira Takata sold 1,500 shares for $1.29M on 2026-05-12, a much smaller sale relative to MegaChips.
  • Director Christine Heckart gifted 9,305 shares on 2026-05-14 — a non-cash transaction with zero economic signal for valuation.
  • SITM reported Q1 2026 net revenue of $113.6M (+88.3% YoY) and non-GAAP EPS of $1.44 on May 6, 2026.
  • All in the cluster are sells by non-C-suite insiders (10% owner and two directors).
  • The cross-filing context includes earnings + insider cluster, which is an AMPLIFIER per actuarial verdicts.

Financial Impact

MegaChips Corp sold ~1.5% of market cap ($311.8M) in a single open-market transaction; $1.29M secondary sale by director Takata.

Risk Factors

  • Further sales by MegaChips Corp if this is part of a larger distribution plan.
  • Downward price pressure from the ~400K share overhang needing to be absorbed.
