What this transaction means for investors
By allocating $172.85 million to this single semiconductor name that now represents 26.47% of reported assets, Turiya Advisors is putting Tower Semiconductor squarely at the center of its portfolio thesis.
The disclosure’s timing is also notable. Tower just posted record fourth quarter revenue of $440.2 million, up 14% year over year, with net profit climbing to $80.1 million, or $0.71 per share, according to its earnings release. Full-year revenue reached $1.57 billion, up 9%, and net profit totaled $220.5 million. Profitability expanded alongside growth, with operating profit rising to $70.8 million in the quarter.
More important for long-term investors is the capital allocation story. Management is executing a $920 million combined investment in SiPho and SiGe capacity, with over 70% of planned SiPho capacity already reserved through 2028 and backed by customer prepayments. That kind of visibility reduces demand risk in a cyclical industry.
Compared with other top holdings, this position is second only to Alphabet and well ahead of diversified industrial bets like Cleveland-Cliffs and GEO. That seemingly makes this a clear conviction play.
