Semtech Corp (SMTC) shares fell 10.01% to $144.21 on Wednesday. The decline followed a data center analyst day where the company outlined long-term growth targets that spooked investors.

What Happened

Semtech reported that it expects an EPS CAGR of 64% to 66% for fiscal years 2026 through 2030. The company also projected fiscal year 2030 revenue of $3.2 billion, driven primarily by data center and LoRa technologies. Despite raising its Q3 EPS view to $1.12 to $1.16 from $1.02 to $1.08, the stock dropped 10% after the event. A Form 8-K filed on October 15, 2026, disclosed the preliminary results under Regulation FD.

What The Data Shows

The stock has moved 21.3% lower over the last eight sessions, falling from $197.20 to $155.15. Semtech currently trades at a P/E of 98.6 with a market cap of $16.1 billion. The 52-week range spans from $60.28 to $201.99. On October 15, the stock printed four fresh 52-week highs and 16 fresh 52-week lows. Options activity showed call buyers dominating as the stock dropped. Recent insider filings show 12 sells totaling $3.8 million in the last 90 days, with no buys. The most recent sales were by CEO Hou Hong Q on October 2, CFO Lin Mark on October 1, and EVP Jason Green on October 7.

What To Watch

Analysts have recently raised price targets, with BMO Capital raising its target to $230 and Stifel raising its target to $220. Investors will monitor how the market digests the new long-term revenue guidance and whether the high valuation multiple sustains the recent price action.
