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.
Price Chart
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.
