Apple on Thursday announced a redesigned blood oxygen feature for some Apple Watch users, following a yearslong intellectual property dispute over the capability.

Apple said the redesigned feature is coming to some Apple Watch Series 9, Series 10 and Apple Watch Ultra 2 users on Thursday. The update was possible because of a recent U.S. Customs ruling, the company said.

In 2023, the International Trade Commission found that Apple’s blood oxygen sensors infringed on intellectual property from Masimo, a medical technology company. Apple paused the sale of some of its watches and began selling modified versions of the wearables without the blood oxygen feature.

“Apple’s teams work tirelessly to create products and services that empower users with industry-leading health, wellness, and safety features that are grounded in science and have privacy at the core,” the company said in a release announcing the feature rollout.

CNBC has reached out to Masimo for comment.

Users who do not currently have the feature will be able to access it by updating their iPhone to iOS 18.6.1 and their Apple Watch to watchOS 11.6.1, Apple said. Users will be able to see their results in the Respiratory section of the Health app.

Apple has been pushing deeper into health care in recent years.

The company recently released a sleep apnea detection feature for Apple Watch users and hearing health features for its AirPods headphones. In February, Apple launched its first major health study in five years.

Warren Buffett’s Berkshire Hathaway revealed a new stake in troubled insurer UnitedHealth last quarter, according to a regulatory filing, a surprising buy because of the company’s current reputation, but perhaps not considering his history of bargain investing.

The Omaha-based conglomerate bought more than 5 million shares in the health care firm for a stake worth about $1.6 billion at the end of June. The stake puts it as the 18th biggest position in the Berkshire portfolio behind Amazon and Constellation Brands, according to VerityData.

Berkshire’s equity portfolio is worth about $300 billion, so it is possible that Buffett’s two investing lieutenants Todd Combs and Ted Weschler were more responsible for this purchase rather than the “Oracle of Omaha” himself. Buffett said one of his investment managers was behind the Amazon investment in 2019.

The insurer’s stock shot up 6% in extended trading following Berkshire’s disclosure.

Shares of UnitedHealth were down nearly 50% for 2025 through Thursday’s close before Buffett’s filing. The largest private health insurer has become the face of a public blowback in this country against the rising costs of health care. UnitedHealth is currently facing a Justice Department investigation into its Medicare billing practices.

In May, the company pulled its annual earnings outlook and CEO Andrew Witty stepped down. Last month, UnitedHealth gave a new 2025 outlook that was well short of Wall Street estimates, hitting the stock further.

Buffett, who’s turning 95 this month, has been critical of the healthcare system in the U.S., calling it a “tapeworm” on the economy due to its high costs. In 2018, he, along with Jeff Bezos and Jamie Dimon, launched a joint venture to improve healthcare for their employees and potentially for all Americans, but it was eventually shut down.

UnitedHealth isn’t the only stock Berkshire picked up recently. In fact, the conglomerate also took small stakes in steel manufacturer Nucor, outdoor advertising company Lamar Advertising and security firm Allegion. Berkshire also got back into homebuilders Lennar and DR Horton.

Shares of Nucor jumped nearly 8% in afterhours trading, while Lennar and DR Horton popped about 3% each.

Buffett also pared his positions in Bank of America and Apple. The Apple stake was cut by about 7%. Berkshire’s largest positions as of the end of the second quarter were Apple, American Express, Bank of America, Coca-Cola and Chevron.

The legendary investor is stepping down as Berkshire CEO at the end of the year, handing over the reins to Greg Abel. Buffett will stay on as chairman of the board. It’s still unclear who will be in charge of Berkshire’s gigantic equity portfolio, though Buffett has alluded that Abel will be making all capital allocation decisions at the conglomerate.

UnitedHealth attracted other buyers last quarter, according to filings, including Michael Burry and Appaloosa Management’s David Tepper. Shares of the insurer are trading at a price-earnings ratio of just under 12, near its lowest in more than a decade.

There was speculation regarding a mystery stock Buffett was buying as Berkshire had asked for permission to keep certain holdings secret last quarter. It turns out the secret stock was a combination of multiple positions and likely the stakes added in DR Horton, Nucor and Lennar “A” shares.

Lyft said Thursday its co-founders, Logan Green and John Zimmer, are stepping down from the ride-hailing services provider’s board, following the completion of a two-year transition plan.

Green and Zimmer began serving as the chair and vice chair of Lyft’s board in 2023 after stepping down as CEO and president, respectively, handing the reins to David Risher, who has been a board member since 2021.

The duo founded Lyft in 2012, with the company now operating across four continents and nearly 1,000 cities.

Sean Aggarwal, who was the chair of Lyft’s board from 2019 to 2023, will reprise his role.

Zimmer is launching a new consumer-focused business venture named YES&, while Green will continue as a venture partner at Autotech Ventures, a firm investing in the mobility and transportation sector.

Lyft, which recently completed its nearly $200 million acquisition of European mobility platform FreeNow, has signed a deal with China’s Baidu 9888.HK to introduce the search-engine giant’s robotaxis in the region.

It posted revenue of $1.59 billion in the second quarter, missing estimates of $1.61 billion, according to data compiled by LSEG.

Rides on Lyft’s platform grew 14% to a record high of 234.8 million in the quarter, slightly below estimates of 235.9 million, per Visible Alpha.
