Semtech's analyst-day growth outlook makes the stock look cheap if guidance holds. Management guided to $3.2B FY30 revenue at 38% CAGR and estimated 70% gross and 48-50% operating margins. Backlog alone underpins more than doubling datacenter revenue in FY27 and FY28, versus the 80% and 70% previously modeled; LoRa's 30% CAGR tops the prior 20% assumption. Later forecasts are more conservative, so growth could beat 38%. At 25x FY30 earnings (January 2030), the stock should trade at $320. x.com  … Show more

Semtech is gaining share in a growing market, with content per unit about to jump and a higher-margin business left after its divestiture. FiberEdge's 800G share rose from 18% to over 50% as transceiver units roughly tripled, and it expects over 50% of 1.6T this year. Content per transceiver rises from high single digits to $80-90 as the industry moves to 3.2T in 18-24 months. Gross margin should start at 64% after the cellular module sale, versus 53% two quarters ago. x.com 

Semtech's valuation already assumes strong execution, so the stock needs growth to keep pace with a fast-expanding optical market. It is one of the few names with real products across all three AI networking layers, from scale-up copper to scale-out optics chips and, via the HieFo laser deal, scale-across. FY26 data center revenue rose 58% to $223M, with over 50% growth guided for FY27. BofA sees the optical market growing from $14B in 2025 to $73B by 2030, a pace that would ease the multiple. … Show more

Semtech is put forward as a stock to own. x.com 

Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com 

Semtech does not deserve its status as a hot optical stock, since it is mostly a low-quality analog business with only a couple of data center parts. The move has been striking, though being wrong is possible. x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

Semtech looks cheap against its earnings, trading at 25x forward earnings when chipmakers usually get 38x. Applying 38x to next year's $5.84 EPS estimate, give or take 12%, puts fair value at $195.14 to $248.36, leaving the stock 24% below where fair value starts. The case leans on the forecast, since the forward earnings read is 397% above the trailing one, and it is a levels-only read off reported earnings and revenue estimates with no fundamental work. x.com 

Semtech is not an attractive holding because of its historic cyclicality, unless the business has materially changed. x.com 

Semtech should lead semiconductors higher once yields eventually behave, and $250 within six months would be no surprise. It is resting on support at its previous all-time highs and is no longer screaming cheap, worth about $210, but it has been extremely strong. Management gave incredible visibility into 2027, so the story is somewhat derisked and now comes down to execution. x.com  x.com
