The planned sale, through Morgan Stanley Smith Barney LLC Executive Financial Services on the NYSE, has an approximate aggregate market value of $302,300.00.

Onto Innovation Inc. completed the previously announced acquisition of 61,123,436 shares, representing 27% of the issued and outstanding common stock of Rigaku Holdings Corporation from Atom Investment, L.P., for an aggregate purchase price of approximately US$720 million. This is a minority equity stake and Onto Innovation will account for the investment under the fair value option method and will not consolidate Rigaku’s financial results. The investment deepens a strategic collaboration focused on advancing X-ray-based process control solutions for semiconductor manufacturing, and Onto Innovation will nominate a director to Rigaku’s board.
Onto Innovation Inc. delivered strong Q2 2026 performance, with revenue of $343.1 million, up 35.3% year over year, and gross margin of 53.4%. Net income was $60.1 million, or $1.21 diluted EPS. For the first half of 2026, revenue reached $635.1 million, a 22.1% increase from the prior year period, while net income was $93.9 million.
Liquidity strengthened sharply: combined cash, cash equivalents and marketable securities rose to about $1.9 billion, driven largely by issuing $1.5 billion of 0.00% convertible senior notes due 2031 and related capped call transactions, alongside $204.9 million of concurrent share repurchases. The planned $710 million purchase of a 27% stake in Rigaku Holdings represents a sizable strategic minority investment expected to close in the second half of 2026. The November 2025 acquisition of Semilab USA contributed $46.1 million of revenue and a $9.0 million operating loss in the first half of 2026.

ONTO Innovation director Su May reported receiving a grant of 761 shares of Common Stock in the form of restricted stock units. These RSUs vest 100% one year from the grant date and each unit converts into one share when settled. After this award, May holds 7,984 shares directly. The reporting person elected to defer settlement of these RSUs under the Onto Innovation Nonqualified Deferred Compensation Plan, so once vested the shares will be issued according to that deferral election.
