Intuitive reached the settlement in October 2026, after a mediation. It will make a one-time payment of $450 million and accept mutually agreed injunctive relief, meaning a court order on how it does business, without admitting liability or wrongdoing.1 It booked the full $450 million as a selling, general and administrative expense in the third quarter. After tax the charge is $347 million , or $0.99 a share, which implies a tax saving of about $103 million .2 The deal still needs preliminary and final court approval. The company says there is no assurance the court will approve it or that class members will not object.3

It equals 6.6% of the $6.80 billion of cash and investments at September 30, about 15% of one quarter's revenue and about 18% of 2025 free cash flow.1 After tax it is about 0.24% of a market value of about $143 billion , using the quarter's 351.6 million average diluted shares and the $407.99 after-hours price.2 Cash and investments exceed total liabilities of $3.23 billion by about $3.57 billion , so debt ratios and interest coverage are not a concern here.3

The hospitals in the class get a cash payment instead of waiting for that trial.1 What the conduct limits require is the open question. Instruments and accessories brought in $1.80 billion of the quarter's $3.05 billion of revenue, so any limit on how Intuitive controls instruments could matter more over time than the one-time cash.2 The release describes only the class action as settled; the two appeals above were still pending in the June 10-Q.3

Adjusted net income rose to $1.05 billion from $867 million .1 The $532 million gap between the two comes from items the adjusted figure leaves out: litigation charges, stock pay of $216 million in the quarter, amortization of acquired intangibles, acquisition items and tax adjustments. Stock pay is a real cost that the company itself says will stay significant and recurring for the foreseeable future.2 Adding back the $0.99 settlement charge, reported earnings would have been about $2.48 a share, up about 27% from $1.95. 3 Two loose ends remain. Total litigation charges were $454.9 million , about $4.9 million more than the settlement, and the per-share table shows $1.00 for litigation against the $0.99 in the text.4 The adjusted $3.00 also includes a $22 million , or $0.06 a share, benefit from refunds of tariffs paid in earlier periods; the second quarter carried a similar $0.08 and the year-earlier quarter none. Without it, adjusted earnings were $2.94, up 22.5% from $2.40. 5
