ONTO

Onto Innovation is a financially pristine semiconductor metrology and inspection vendor — zero long-term debt, $346M cash (+62.5%), and a fortress 0.13x liabilities/equity ratio. The franchise is real, levered to advanced packaging and metrology for AI chips and advanced nodes, with revenue heavily concentrated in Taiwan (32%) and South Korea (28%). But the FY2026 (fiscal year ended January 3, 2026) results show the cyclical cracks: revenue grew only 1.8% to $1.01B while net income fell 32.2% to $137M and diluted EPS dropped 31.5% to $2.78. The MD&A attributes the systems softness to fewer inspection units shipped for AI advanced-packaging, and gross margin compressed from 52.2% to 49.7% on restructuring and excess/obsolete inventory write-downs.

The valuation is the core problem. At $333.76 the stock trades at 120.1x FY diluted EPS and 16.5x sales, yet it earns only a 6.5% return on equity and just delivered declining profitability. That is a multiple that demands strong, accelerating growth; instead the company posted a margin-led earnings decline. R&D spending rose 15.9% to $132M (now 13.1% of revenue), which is the right long-term move but pressures near-term operating margin (down to 13.2% from 19.0%).
