New York, May 24, 2026, 10:04 (EDT)
Astera Labs finished the week on a high, with shares up 3.04% Friday to close at a record $306.88. That’s a gain of roughly 32% from last Friday. The U.S. stock market is closed for the weekend and for Memorial Day on Monday, May 25, so Nasdaq stocks, including Astera, won’t trade until Tuesday.
Astera’s move drew attention this time because last week’s rally wasn’t only about AI. Investors started pricing Astera as a bigger play on the data-center “fabric” trade, which covers the high-speed connections that tie together processors, memory, and networking chips inside AI server racks.
Astera sells semiconductor connectivity parts aimed at cloud and AI setups. It offers PCIe, CXL, and Ethernet chips and modules, Reuters reported. Basically, these parts move data fast between processors, memory and servers.
Scorpio and management drive Astera stock gains this week
Astera shares surged after management events and renewed attention on Scorpio, its AI switch line. The stock jumped 13.30% Tuesday, 17.69% Wednesday, picked up 3.60% Thursday and added another 3.04% Friday. Monday saw a decline, according to market data.
Astera’s latest move goes back to its May 5 earnings. The company posted first-quarter revenue of $308.4 million, up 93% year over year, and reported a GAAP gross margin of 76.3%. For the June quarter, Astera guided revenue to a range of $355 million to $365 million. CEO Jitendra Mohan said demand for the PCIe 6 line was “robust.” Astera Labs
Stocks got a lift as hopes in the Middle East and a good earnings run pushed sentiment higher, Reuters reported Friday. The Philadelphia Semiconductor Index was up, but Nvidia dropped 1.90%. James St. Aubin, chief investment officer at Ocean Park Asset Management, told Reuters earnings and data make the fundamental case “really solid.” Reuters
Astera plays in a tight space but it matters. Nvidia is still the key name for AI compute demand. Broadcom and Marvell are the big comparisons for networking and custom hardware. Astera wants the spot in between, working on connectivity, switching, and software to ease bottlenecks in AI racks.
Target changes by analysts got some notice. Markets Insider pointed to a May 19 Evercore note that kept a buy and set a $297 price target, along with other recent buy ratings from J.P. Morgan, Morgan Stanley, RBC, Stifel and Needham. The stock closed above $300 on Friday, so part of that bullish view is in the current share price.
Some outside analysts spelled it out. Patrick Moorhead at Moor Insights & Strategy said the bottleneck is moving “off the GPU and into the fabric.” Dylan Patel of SemiAnalysis said interconnect is where GPU use “goes to die” for AI labs. Both spoke at Astera’s Scorpio launch. Astera Labs
Short trading week ahead, but plenty for investors to watch. U.S. markets are closed Monday and reopen Tuesday, May 26. Astera is on the schedule to speak at TD Cowen’s tech conference in New York on Wednesday, May 27. The focus will be on Scorpio production ramps, custom product updates and news around optical connectivity.
But with the rally, there’s not much margin for error. Astera’s filings show insiders filing recent Form 144 notices for planned share sales, and a Form 4 on May 21 showed President and COO Sanjay Gajendra selling under a Rule 10b5-1 trading plan. That kind of selling doesn’t automatically mean insiders expect bad news, but it could give bears something to point to if the stock stops moving higher.
Astera has a clear risk. AI spending may hold up, but investors could be left waiting if the company can’t turn buzz for Scorpio into enough shipments. Any weakness in gross margin, a hint of caution from management at the Cowen event, or a move out of chip names after the recent rally could turn a record close into a tough base for the stock.
