Watchlist shifts & M&A
Small cap moves are showing up on sector watchlists: VRT acquired BMarko to boost capacity, and SNDK was listed as joining the Nasdaq‑100 replacing TEAM (x.com). Technical screens also flagged names like MRVL, LITE, CIEN and MU as tightening setups that traders are eyeing for potential entries (x.com).
Vertiv said Monday it bought BMarko Structures, adding factory capacity just as Sandisk is set to enter the Nasdaq-100 next week. (prnewswire.com) Vertiv announced the acquisition on April 13, 2026, saying BMarko’s custom structural fabrication will be folded into its North America infrastructure business. The company said the deal adds engineering control and manufacturing capacity for prefabricated and converged data-center systems. (prnewswire.com) BMarko recently expanded its South Carolina engineering and fabrication site to about 560,000 square feet, according to Vertiv and follow-on coverage of the filing. Vertiv said the facility sits near its existing Infrastructure Solutions operations and had already worked with Vertiv on long-term projects. (prnewswire.com; gurufocus.com) Nasdaq said on April 10 that Sandisk will replace Atlassian in the Nasdaq-100 before the market opens on Monday, April 20, 2026. The index includes 100 of the largest non-financial companies listed on Nasdaq, so membership can trigger buying by index funds and benchmark trackers. (finance.yahoo.com; indexes.nasdaqomx.com) Those two moves land in the same part of the market: companies tied to the build-out of artificial-intelligence infrastructure. Vertiv sells the power, cooling and physical systems around data centers, while Sandisk sells memory and storage products that ride the same spending cycle. (vertiv.com; indexes.nasdaqomx.com) The watchlist names traders are circling sit in that supply chain too. Marvell says its chips power artificial-intelligence, cloud and network infrastructure; Lumentum has been pitching optical products for scale-up and scale-out artificial-intelligence networks; Ciena reported first-quarter fiscal 2026 revenue of $1.43 billion, up 33% from a year earlier; and Micron has said demand for high-bandwidth memory remains unusually strong. (investor.marvell.com; investor.lumentum.com; quartr.com; finance.yahoo.com) Marvell and Nvidia said on March 31 they would connect Marvell products to Nvidia’s NVLink Fusion ecosystem, extending Marvell’s role in artificial-intelligence systems. Lumentum said in March it was demonstrating optical technologies for “scale-out, scale-up and scale-across” artificial-intelligence infrastructure at the Optical Fiber Communication Conference. (tmcnet.com; investor.lumentum.com) Ciena’s latest quarter gave the networking side of that theme hard numbers. The company said cloud-provider revenue rose enough to help push total first-quarter fiscal 2026 sales to a record $1.43 billion, while adjusted earnings per share reached $1.35. (quartr.com; finance.yahoo.com) Micron’s latest read-through has been even simpler: memory for artificial-intelligence servers is tight. Reports tied to the company’s recent disclosures said Micron’s 2026 output of high-bandwidth memory was already sold out, a sign that suppliers across chips, optics and power gear are being watched together. (finance.yahoo.com; markets.financialcontent.com) For now, the calendar is clear. Vertiv’s acquisition is already announced, and Sandisk’s index change is scheduled for April 20, giving traders two concrete dates around a group of stocks already clustered on artificial-intelligence infrastructure screens.
