Needham’s Thematic Outlook on Networking and Optical Technology Stocks

Needham has compiled a shortlist of seven publicly‑traded companies operating in the communications and enterprise‑infrastructure space that are expected to deliver strong quarterly and fiscal‑year performance, primarily driven by accelerating demand for data‑center infrastructure, transceiver production, and AI‑related networking equipment.

Applied Optoelectronics Inc (NASDAQ:AAOI)

Needham projects AAOI’s second‑quarter fiscal 2026 revenue to fall toward the higher end of its $180 million‑$198 million guidance, with the Data Center segment alone expected to generate $113 million—representing 38 % quarter‑over‑quarter growth. Management is anticipated to comment on hyperscaler order progress and the impact on the full‑year fiscal 2026 revenue target, which was previously raised to roughly $1.1 billion. The company has also begun construction to expand its Texas manufacturing capacity and entered an at‑the‑market equity agreement that could raise up to $600 million.

Arista Networks Inc (NYSE:ANET)

Arista is expected to post a top‑line beat with approximately 28 % year‑over‑year revenue growth, supported by a 54 % YoY increase in billings for the first quarter of fiscal 2026, driven by AI workloads and deferred‑revenue dynamics. Needham notes that Google could become a new 10 % customer in 2026, and anticipates management to lift the fiscal 2026 AI‑revenue target from $3.5 billion to a higher figure. The firm recently launched the 7060XE7 Series—a 1.6 Tbps networking platform for AI infrastructure—and received an upgrade to a Buy rating from Erste Group.

Coherent Inc (NYSE:COHR)

Coherent is projected to beat the upper bound of its fourth‑quarter fiscal 2026 revenue guidance of $1.91 billion‑$2.05 billion, with analysts modeling $1.52 billion for the Data Center and Networking segment. The company is aggressively expanding internal indium‑phosphide (InP) laser production on new 6‑inch wafer equipment and shipped its first 6‑inch‑fab transceiver in the first quarter of fiscal 2026. Coherent will receive up to $50 million in CHIPS Act funding to expand its Texas facility and has secured a three‑year InP wafer supply agreement with AXT Inc.

Extreme Networks Inc (NASDAQ:EXTR)

Needham expects Extreme Networks to slightly beat both revenue and earnings expectations after the company guided fourth‑quarter fiscal 2026 revenue to $330 million‑$335 million with EPS of $0.28‑$0.30. Management has indicated that memory‑cost inflation is under control, with supply secured through at least 2027. The firm launched a new multi‑beam wireless solution targeting high‑density venues, and both Rosenblatt and BofA Securities have raised their price targets on the stock.

Fabrinet Inc (NYSE:FN)

Fabrinet is forecast to deliver a solid beat versus its fourth‑quarter fiscal 2026 revenue guidance of $1.25 billion‑$1.29 billion, and analysts anticipate a raise for first‑quarter fiscal 2027 revenue versus consensus of $1.32 billion. In its third‑quarter fiscal 2026 report, Fabrinet disclosed record revenue of $1.214 billion and non‑GAAP earnings per share of $3.72, both surpassing expectations.

Lumentum Inc (NASDAQ:LITE)

The analyst expects Lumentum to exceed its revenue guidance range of $960 million‑$1.010 billion, with particular investor focus on forward‑quarter guidance driven by transceiver growth and optical‑carrier‑signal (OCS) ramp‑up. Lumentum was added to the Nasdaq‑100 Index on May 18, 2026.

Viavi Solutions Inc (NASDAQ:VIAV)

Viavi is projected to post modest upside versus its fourth‑quarter fiscal 2026 guidance of $427 million‑$437 million, with an additional constructive outlook 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 Viavi launched a new validation solution for AI data‑center networks.

Overall Implications

Needham’s analysis underscores a sector‑wide expectation of revenue beats and product‑launch momentum across the highlighted firms, reflecting robust demand in data‑center and AI‑driven networking markets. The guidance upgrades, capacity expansions, and strategic partnerships (e.g., AAOI’s Texas expansion, Coherent’s CHIPS Act funding, Extreme’s memory‑cost mitigation) collectively suggest a favorable near‑term outlook for investors targeting the networking and optical technology space.
