Strong AI-Driven Optical Communication Demand; Target Price Raised to $175

Overview

Morgan Stanley’s report highlights accelerating growth momentum for Semtech in AI-driven optical communications. Sustained strong demand for 800G optical modules, along with upcoming volume ramp of ACC (Active Copper Cables) and 1.6T optical modules, has significantly improved the company’s data center business outlook. Although recent stock price appreciation has led to a relatively full valuation, improved visibility and upward revisions to earnings forecasts prompted the firm to raise its target price to $175 while maintaining an 'Equal-weight' rating.

Core views

The data center segment has become the core growth engine. Latest quarterly results show Semtech’s data center revenue reached a record $71.6 million, up 14% sequentially and 39% year-over-year, primarily driven by strong demand for 800G FiberEdge TIAs in both traditional optical modules and LPO (Linear-drive Pluggable Optics) deployments. Management noted exceptionally strong orders and backlog, significantly enhancing forward visibility. New product lines are driving continued growth. Beyond mature 800G offerings, CopperEdge/ACC revenue began contributing in Q1 and has already secured dominant share with major hyperscale customers, with significant volume expected within the year. Additionally, initial revenue from 1.6T optical modules is expected to start in Q2, with substantial growth anticipated in the second half of the year. Accordingly, the firm has sharply revised its FY27 data center growth forecast upward from over 60% to nearly doubling (~100%). LoRa business shows steady growth. On the non-data-center side, LoRa revenue reached $44.5 million, up 12% sequentially and 14% year-over-year. Demand is broad-based across smart infrastructure and industrial IoT applications, with favorable supply-demand dynamics supporting pricing. Management guided for LoRa revenue to grow more than 15% sequentially in Q2. Meanwhile, the Sierra Wireless cellular module divestiture is nearing completion. Financial forecasts and valuation have been upgraded. Based on these positive developments, Morgan Stanley has substantially raised its earnings forecasts: projecting 2026 and 2027 revenue growth of 31.0% and 21.3%, respectively; and revising Non-GAAP EPS from $2.24/$2.98 to $2.72/$3.67. The new $175 target price is derived using a 48x P/E multiple on FY27 Non-GAAP EPS of $3.67. While this multiple is above historical averages, it is deemed reasonable compared to small-cap peers with similar AI exposure.

Analysis framework

The firm employs a combined top-down and bottom-up analytical approach. First, it tracks AI data center capex trends to confirm sustained demand for 800G and higher-speed optical interconnects. Second, it breaks down the company’s product pipeline, distinguishing between mature products (800G TIA) and emerging growth drivers (ACC/CopperEdge, 1.6T), evaluating production ramp timelines and customer penetration rates. Finally, incorporating management’s order visibility, it rebuilds revenue growth and margin models and benchmarks valuation against small-cap semiconductor peers with comparable AI exposure to determine an appropriate P/E multiple.

Methodology notes

• Valuation MethodPE/PEG valuation

  Applying a specific P/E multiple to next year’s expected EPS

  The report uses FY27 estimated Non-GAAP EPS multiplied by a 48x P/E to derive the target price. This method is commonly used for growth-oriented tech companies, assessing valuation reasonableness by comparing multiples of peers with similar AI growth narratives.

• Industry/Sector Analysis FrameworkVolume-price decomposition

  Breaking down revenue growth into volume and price components

  In analyzing the LoRa business, the report notes 'favorable supply-demand dynamics continue to support pricing,' implying growth stems not only from volume expansion but also price support—a key factor in assessing gross margin trajectory.

• Event Arbitrage & Behavioral FinanceExpectation Gap / Guidance Management

  Deviation between actual results/guidance and market consensus expectations

  The report details discrepancies between actual performance, management guidance, and both Street consensus and the firm’s own prior estimates, highlighting significant beats in revenue and earnings as the primary driver behind the stock price and rating adjustments.

• Semtech Corp. (SMTC.US)

  Direct beneficiary; core supplier in AI optical communications and LoRa

  Strengths

  Market leadership in 800G TIA, dominant ACC share with hyperscalers, robust LoRa ecosystem

  Weaknesses

  Valuation at historical highs, high reliance on a single hyperscale customer

  Comparison

  Commands premium vs. general analog peers but trades in line with AI-focused small-cap peers

  Risks

  Macroeconomic uncertainty, high leverage, slower-than-expected adoption of new technologies

Key data

• Q1 Data Center Revenue$71.6 millionUp 14% QoQ, 39% YoY—record high
• Q1 Total Revenue$291 millionUp 6.1% QoQ, 15.9% YoY—above expectations
• Q1 Non-GAAP EPS$0.51Above consensus of $0.45 and firm estimate of $0.46
• FY27 Data Center Growth Forecast~100%Sharply revised upward from previous >50%
• FY27E Non-GAAP EPS$3.67Raised from prior $2.98
• New Target Price$175Based on 48x FY27E EPS, previously $155

Impact & implications

The report argues that Semtech is evolving from a standalone optical component supplier into a broader AI interconnect platform provider, encompassing TIAs, ACC, lasers, and future CPO/XPO architectures. This transformation significantly expands its content opportunity per AI data center deployment. In the near term, volume ramps of 800G and ACC ensure high-growth visibility for coming quarters; long-term, the company’s execution on next-generation photonic integration will determine its market share capture. For investors, while valuation is no longer cheap, continued earnings upgrades may offset valuation pressure.

Risks

• Failure to commercialize new data center opportunities
• Slowing capex by hyperscale cloud providers, reducing data center growth outlook
• Macro weakness, ongoing tariffs, and geopolitical challenges affecting analog chip recovery and consumer spending
• Financial risk stemming from the company’s high leverage

What to watch

• Announcements of new data center customer partnerships
• Increased deployment of LPO/CPO in optical interconnects
• Volume ramp progress of ACC products with major hyperscalers
• Revenue ramp trajectory of 1.6T optical modules from H2 2026 through 2027
• Final closing of the Sierra Wireless divestiture
