$1.3 billion is the oddest number in Onto Innovation’s latest filing. The company’s cash balance rose from $217.5 million a year earlier, a 476.3% jump, even as the business generated less operating cash over the first six months.
The three months ended June 30, 2026 looked strong on the income statement. Revenue rose 35.3% to $343.1 million from $253.6 million in the comparable period, while operating income nearly doubled to $63.5 million. Gross margin widened from 48.2% to 53.4%.
Onto says the engine was demand for inspection and metrology systems used in advanced packaging and advanced-node semiconductor applications. Management also points to a more profitable product mix:
"This margin increase was primarily driven by a favorable shift in sales mix as product sales move toward high-margin inspection and metrology product lines."

That makes the profit improvement fairly legible: Onto sold more of the products it says carry higher margins. The less tidy part sits below net income, where inventory grew 40.3%, faster than revenue, and accounts receivable rose 18.2%.
Onto disclosed that its six-month operating cash flow decreased from the comparable period, citing the timing of receivable payments and higher inventory tied to revenue growth. The cash balance itself was lifted mainly by financing, not by the operating surge:
"This increase was primarily the result of $1.2 billion of cash provided by financing activities and $87.8 million of cash generated from operating activities partially offset by capital expenditures of $7.2 million."

So the filing presents two different kinds of strength. The operating business produced faster sales, wider margins, and a 97.1% increase in operating income. The balance-sheet cash headline came mostly from financing, while working capital absorbed cash during the six-month period.
That distinction matters because a cash balance can look enormous without being the same thing as cash generated by selling inspection equipment. Onto’s own explanation puts operating cash at $87.8 million against $1.2 billion from financing activities. Inventory and receivables also grew alongside the sales increase, leaving the next conversion step unreported here.
The financing context includes Goldman Sachs, which Onto identifies as a lender connection. The company disclosed the end of a bridge commitment after its 2031 notes offering and capped-call transactions:
"On May 21, 2026, following successful execution of the 2031 Notes offering and Capped Call Transactions, we 28 Table of Contents delivered an executed Notice of Bridge Commitment Termination to Goldman Sachs, terminating the Bridge Commitment in full."

That provides context on the financing activity, but it does not answer how quickly the working-capital build turns back into operating cash. At the latest close, Onto shares were $268.50, down 2.6% on the day, after a recent run of higher closes. The market context is a company valued at 96.7 times earnings, though the filing itself leaves the operating question more immediate than the multiple.
Onto’s next quarterly report will need to put the sales growth, inventory, receivables, and operating cash flow on the same page. How much of Onto’s $1.3 billion cash balance came from financing rather than operations?
Onto’s latest 10-Q reports stronger sales and margins, higher inventory and receivables, and cash supplied primarily by financing activities.
