Intel said on Wednesday that it had appointed Lip-Bu Tan as its new CEO, as the chipmaker attempts to recover from a tumultuous four-year run under Pat Gelsinger.

Tan was previously CEO of Cadence Design Systems, which makes software used by all the major chip designers, including Intel. He was an Intel board member but departed last year, citing other commitments.

Tan replaces interim co-CEOs David Zinsner and MJ Holthaus, who took over in December when former Intel CEO Patrick Gelsinger was ousted. Tan is also rejoining Intel’s board.

The appointment closes a chaotic chapter in Intel’s history, as investors pressured the semiconductor company to cut costs and spin off businesses due to declining sales and an inability to crack the booming artificial intelligence market.

Intel shares rose over 12% in extended trading on Wednesday.

Tan becomes the fourth permanent CEO at Intel in seven years. Following Brian Krzanich’s resignation in 2018, after the revelations of an inappropriate relationship with an employee, Bob Swan took the helm in Jan. 2019. He departed two years later after Intel suffered numerous blows from competitors and chip delays. Swan was succeeded by Gelsinger in 2021.

Gelsinger took over with a bold plan to transform Intel’s business to manufacture chips for other companies in addition to its own, becoming a foundry. But Intel’s overall products revenue continued to decline, and investors fretted over the significant capital expenditures needed for such massive chip production, including constructing a $20 billion dollar factory complex in Ohio.

Last fall, after a disappointing earnings report, Intel appeared to be for sale, and reportedly drew interest from rival companies including Qualcomm. Analysts assessed the possibility of Intel spinning off its foundry division or selling its products division — including server and PC chips — to a rival.

In AI, Intel has gotten trounced by Nvidia, whose graphics processing units (GPUs) have become the chip of choice for developers over the past few years.

In January, Intel issued a weak forecast even as it beat on earnings and revenue. The company pointed to seasonality, economic conditions and competition, and said clients are digesting inventory. The prospect of tariffs was adding to the uncertainty, Zinsner said.

Intel said that Zinsner will return to his previous role of CFO. Holthaus will remain in charge of Intel Products.

Intel was removed from the Dow Jones Industrial Average in November and was replaced by Nvidia, reflecting the dramatic change of fortune in the semiconductor industry. Intel shares lost 60% of their value last year, while Nvidia’s stock price soared 171%. At Wednesday’s close, Intel’s market cap was $89.5 billion, less than one-thirtieth of Nvidia’s valuation.

Shares of iRobot plunged more than 30% on Wednesday after it said there is “substantial doubt” about its ability to stay in business.

The Roomba maker’s financial outlook has darkened since Amazon abandoned its planned $1.7 billion acquisition of the company in January 2024, citing regulatory scrutiny. Since then, iRobot has struggled to generate cash and pay off debts.

Massachusetts-based iRobot has been restructuring since the Amazon deal plunged into uncertainty. The company has laid off 51% of its workforce since the end of 2023, and iRobot has looked to reignite revenue growth by overhauling its product lineup. The company on Tuesday launched eight new Roombas in the hopes of “better positioning iRobot as the leader in the category that we created,” CEO Gary Cohen said in a statement.

“There can be no assurance that the new product launches will be successful,” iRobot said in its Wednesday earnings statement, citing limited consumer demand, tariff uncertainty and heightened competition.

“Given these uncertainties and the implication they may have on the company’s financials, there is substantial doubt about the company’s ability to continue as a going concern for a period of at least 12 months,” iRobot said in its earnings report.

The company’s fourth-quarter revenue sagged 44% year over year to $172 million, missing estimates of $180.8 million, according to FactSet. The Roomba maker posted a net loss of $77.1 million, or $2.52 per share. Excluding a one-time “manufacturing transition charge,” iRobot had a loss of $2.06 a share, exceeding the $1.73 per share projected by analysts surveyed by FactSet.

In July 2023, iRobot took a $200 million loan from the Carlyle Group to fund the company’s operations as a stopgap until the Amazon deal closed. The company amended the loan for a temporary waiver on certain financial obligations, which requires iRobot to pay a fee of $3.6 million.

As part of Wednesday’s report, iRobot said its board has initiated a strategic review of the business and is considering alternatives that could include refinancing its debt and exploring a potential sale. The board hasn’t set a deadline for when its review will conclude, the company said.

Shortly after the Amazon deal fell apart, Amazon CEO Andy Jassy criticized regulators’ approach to its iRobot acquisition. European Union regulators threatened to block the deal, and the Federal Trade Commission in the U.S. was reportedly expected to challenge the acquisition in court.

The proposed merger, which was announced in late 2022, would have allowed iRobot to scale and better compete with its rivals, Jassy said. Several of the fastest-growing robotic vacuum businesses are based in China, such as Anker, Ecovacs and Roborock, all of which have eaten into iRobot’s share of the market.

“We abdicate the acquisition, iRobot lays off a third of its staff, the stock price completely tanks, and now, there’s a real question of whether they’re going to be a going concern,” Jassy told CNBC’s Andrew Ross Sorkin in an interview last April.

The Federal Trade Commission asked a judge in Seattle to delay the start of its trial accusing Amazon of duping consumers into signing up for its Prime program, citing resource constraints.

Attorneys for the FTC made the request during a status hearing on Wednesday before Judge John Chun in the U.S. District Court for the Western District of Washington. Chun had set a Sept. 22 start date for the trial.

Jonathan Cohen, an attorney for the FTC, asked Chun for a two-month continuance on the case due to staffing and budgetary shortfalls.

The FTC’s request comes amid a push by the Trump administration’s Department of Government Efficiency to reduce spending. DOGE, which is led by tech baron Elon Musk, has slashed the federal government’s workforce by more than 62,000 workers in February alone.

“We have lost employees in the agency, in our division and on our case team,” Cohen said.

Chun asked Cohen how the FTC’s situation “will be different in two months” if the agency is “in crisis now, as far as resources.” Cohen responded by saying that he “cannot guarantee if things won’t be even worse.” He pointed to the possibility that the FTC may have to move to another office “unexpectedly,” which could hamper its ability to prepare for the trial.

“But there’s a lot of reason to believe … we may have been through the brunt of it, at least for a little while,” Cohen said.

John Hueston, an attorney for Amazon, disputed Cohen’s request to push back the trial date.

“There has been no showing on this call that the government does not have the resources to proceed to trial with the trial date as presently set,” Hueston said. “What I heard is that they’ve got the whole trial team still intact. Maybe there’s going to be an office move. And by the way, both in government and private sector, I’ve never heard of an office move being more than a few days disruptive.”

The FTC sued Amazon in June 2023, alleging that the online retailer was deceiving millions of customers into signing up for its Prime program and sabotaging their attempts to cancel it. Amazon has denied any wrongdoing, calling the FTC’s claims “wrong on the facts and the law.”

“Amazon tricked and trapped people into recurring subscriptions without their consent, not only frustrating users but also costing them significant money,” former FTC Chair Lina Khan said at the time.

The FTC brought a separate case against Amazon in September 2023 accusing it of wielding an illegal monopoly. The agency alleged that Amazon prevents sellers from offering cheaper prices elsewhere through its anti-discounting measures. That case is set to go to trial in October 2026.

In the time since the FTC filed its cases, Khan has been replaced as the head of the FTC by Trump appointee Andrew Ferguson. Tech companies, which are the target of several regulatory agencies, have sought to curry favor with Trump, including Amazon founder and executive chairman Jeff Bezos. He attended President Donald Trump’s inauguration in January, and Amazon was among several tech companies to donate $1 million to Trump’s inauguration committee.
