Tower Semi CEO Sold $45M Near Peak; Q3 Hits $526M Record
NEW YORK, November 8 —
Three months after Tower Semiconductor Ltd. (TSEM) CEO Russell Craig Ellwanger sold $45.61 million of shares at $243 to $264 apiece, the stock has surrendered nearly half that value. The company just reported the strongest quarter in its history: record revenue, a doubling net margin, and Q4 guidance that sets up a $2 billion year.
- Q3 revenue hit a record $526 million, up 36% from $396 million year-earlier; Q4 guidance midpoint is $600 million.
- Net income doubled to $120 million at a 23% margin, up from $54 million and 14% in Q3 2025.
- CEO Russell Craig Ellwanger made 27 open-market sales on August 10-11, totaling $45.61 million, with zero purchases.
Silicon Photonics Is Doing the Work
Tower Semiconductor Ltd. is an independent foundry that offers customizable process platforms across silicon photonics, silicon germanium, mixed-signal CMOS, RF CMOS, image sensors, and integrated power management. Its customers are device makers who cannot or choose not to build their own fabs. The SiPho platform generated roughly $240 million in Q3 2026 revenue alone, with management projecting the annualized run rate to exceed $1.1 billion by Q4. That single platform is why a company that posted $1.57 billion in full-year 2025 revenue now guides to $2 billion for 2026. BCD revenue also grew, up approximately 10% year-over-year, with blended prices forecast to rise 20% in 2027.
An Exit at Twice Today's Price
The stock's current level makes the CEO's August transactions look prescient. Per regulatory filings, Russell Craig Ellwanger executed 27 open-market sales on August 10-11, 2026, at prices between $243.32 and $263.78, collecting $45.61 million against zero purchases. The stock has since halved to $137.34. That gap coincides with a quarter in which gross profit rose 92% to $179 million, operating profit reached 2.5 times the year-prior figure, and diluted EPS came in at $1.05 against a year-earlier $0.47. Whether Ellwanger saw multiple compression coming or the market has mispriced a growing foundry is a question the Q3 results cannot answer. The DCF calculator can help size the discount.

The Q4 Number That Changes the Frame
Q4 guidance of $600 million, a 14% sequential jump from Q3's $526 million, is the first checkpoint for whether the stock's decline was a valuation call or indiscriminate sector selling. The company is mid-stride through a $920 million CapEx plan for SiPho and SiGe capacity; roughly 65% is paid, the balance due across Q4 and H1 2027, with management expecting full return within one year. Tower has beaten consensus EPS estimates in each of the past three reported quarters; a miss on that Q4 target would sharpen the CEO-timing argument, while a beat would reopen the sector-dislocation case.

Tower Semiconductor just reported the strongest quarter in its history — record revenue of $526 million, a 23% net margin that more than doubled year-over-year, and Q4 guidance of $600 million — yet the stock trades at $137.34, far below the $243–$264 range at which CEO Russell Craig Ellwanger sold shares across 27 open-market transactions just three months ago. Whether the CEO's exit reflects a rational call on valuation or an overreaction by a market selling the sector indiscriminately is the question the results alone cannot answer.
