Needham has identified a group of communications and enterprise infrastructure companies that it believes are positioned to report stronger results than market guidance would imply, driven largely by demand linked to data-center buildouts, AI infrastructure and telecommunications equipment upgrades.
The firm focused on firms operating in optical components, transceivers and switching platforms, noting where revenue guidance, capacity expansions and customer progress will be closely watched by investors ahead of quarterly earnings. Below is a company-by-company summary of the key expectations Needham outlined and the specific metrics and developments it highlighted.
Applied Optoelectronics (NASDAQ:AAOI)
Needham projects Applied Optoelectronics will report second quarter fiscal 2026 revenue near the upper end of its $180 million to $198 million guidance range. Attention is centered on the Data Center segment, where consensus models approximately $113 million in revenue, a 38% sequential increase. Investors will be watching commentary on hyperscaler order progression and any effects on the company’s fiscal 2026 revenue outlook, which was previously raised to about $1.1 billion. According to Needham, a second-quarter upside coupled with meeting the third-quarter fiscal 2026 revenue consensus of $278 million would be important to support the stock.
Needham also noted that Applied Optoelectronics has started construction to expand manufacturing capacity in Texas and has put in place an at-the-market equity program covering up to $600 million.
Arista Networks (NYSE:ANET)
The brokerage expects Arista to deliver a typical top-line beat versus guidance and to report approximately 28% year-over-year revenue growth. The firm cited billings growth of 54% year-over-year in the first quarter of fiscal 2026, attributing strength to AI-related demand and deferred revenue dynamics. Needham added that Arista appears to be gaining share with Google, which could emerge as a 10% customer in 2026, and anticipates management may raise its 2026 AI revenue target from $3.5 billion. Needham suggests investors will be watching for management to lift fiscal 2026 guidance toward at least 30% growth from the roughly 28% level.
Arista has introduced the 7060XE7 Series, a 1.6T networking platform designed for AI infrastructure, and the company recently received an upgrade to a Buy rating from Erste Group, according to Needham’s review.
Coherent (NYSE:COHR)
Needham expects Coherent to beat the high end of its fourth quarter fiscal 2026 revenue guidance range of $1.91 billion to $2.05 billion, driven by strength in Data Center and Networking where consensus models $1.52 billion. The firm pointed to Coherent’s accelerated ramp of internal indium phosphide (InP) laser production using new 6-inch wafer equipment and noted the company shipped its first transceiver produced from a 6-inch fab in the first quarter of fiscal 2026.
Coherent is slated to receive up to $50 million in CHIPS Act funding to expand its Texas facility and has secured a three-year indium phosphide wafer supply agreement with AXT Inc., items Needham highlighted as supportive of capacity expansion.
Extreme Networks (NASDAQ:EXTR)
Needham expects Extreme Networks to modestly beat both revenue and earnings guidance for the fourth quarter of fiscal 2026, where management previously guided revenue of $330 million to $335 million and earnings per share of $0.28 to $0.30. The firm observed that the company has been addressing memory cost inflation and that supply appears secured through at least 2027.
Extreme has launched a new multi-beam wireless solution targeted at high-density venues, and the stock has seen constructive gestures from other firms, with Rosenblatt and BofA Securities raising price targets, according to Needham.
Fabrinet (NYSE:FN)
For Fabrinet, Needham expects a solid beat on fourth quarter fiscal 2026 revenue relative to guidance of $1.25 billion to $1.29 billion, and anticipates management will raise first quarter fiscal 2027 expectations versus the consensus of $1.32 billion. Fabrinet reported record revenue of $1.214 billion and non-GAAP earnings per share of $3.72 in its third quarter fiscal 2026 report, both figures that surpassed expectations and were noted by Needham.
Lumentum (NASDAQ:LITE)
Needham looks for Lumentum to outperform its revenue guidance range of $960 million to $1,010 million, with particular investor focus on forward-looking commentary tied to transceiver growth and an optical circuit switch (OCS) ramp. The firm also noted Lumentum was added to the Nasdaq-100 Index on May 18, 2026.
Viavi Solutions (NASDAQ:VIAV)
Needham expects modest upside to Viavi’s fourth quarter fiscal 2026 results versus guidance of $427 million to $437 million, and anticipates another constructive guide for the first quarter of fiscal 2027. S&P Global Ratings upgraded Viavi to BB from B+ after the company repaid its term loan B, and the company has introduced a new validation solution aimed at AI data-center networks, items Needham flagged as relevant to near-term momentum.
Summary
Overall, Needham’s note highlights a set of companies across networking and optical technology that are expected to report results above guidance or demonstrate constructive forward commentary. The analysis places emphasis on data-center and AI-related demand drivers, manufacturing capacity ramps in Texas, transceiver production milestones and supply agreements that underpin revenue expectations.
Key points
- Several companies are expected to report revenue above guidance driven by data-center and AI infrastructure demand.
- Manufacturing capacity expansions and supply agreements - including Texas facility buildouts and wafer supply deals - are central to the outlook for optical and transceiver suppliers.
- Networking billings and AI-related product launches are contributing to anticipated top-line strength for switching and networking vendors.
Risks and uncertainties
- Company guidance and investor expectations could be disappointed if hyperscaler order progress or bookings momentum does not materialize as projected, impacting revenue outlooks in the data-center supply chain.
- Supply chain or manufacturing execution issues related to capacity expansions and wafer production ramps could delay transceiver shipment schedules and revenue recognition.
- Cost pressures, such as memory inflation for networking equipment, could erode margins if not managed or if supply assurances change before 2027.
Needham’s note provides a framework for investors to evaluate upcoming quarterly reports from firms tied to the data-center and optical ecosystem, focusing on the specific metrics and operational milestones that would validate upbeat expectations.
