# Semtech locked in Tower wafer capacity and a $2.1 billion data-center target; the stock fell 10%

> On October 13 Semtech agreed to fund dedicated germanium wafer capacity at Tower Semiconductor across three countries; two days later it raised guidance and set a $2.1 billion data-center target for 2030. The stock closed down 10% anyway, at 97 times earnings.

On October 13, [Semtech](https://theinference.org/markets/companies/semtech) [agreed to fund dedicated silicon-germanium capacity at Tower Semiconductor's fabs in the United States, Israel and Japan](https://markets.businessinsider.com/news/stocks/tower-semiconductor-and-semtech-expand-sige-partnership-to-scale-power-efficient-analog-connectivity-for-data-centers-1036620080), turning a 20-year manufacturing relationship into a multi-year reservation. [1] Two days later it [raised guidance and set a 2030 target](https://www.sec.gov/Archives/edgar/data/88941/000008894126000041/0000088941-26-000041-index.htm). [2] The stock still [closed down 10.01% at $144.21](https://www.tokenpost.com/news/business/33074). [3]

## A 20-year partnership becomes a reservation

Silicon germanium is the material behind the analog front end that drives the signals on optical links and active copper cables between AI racks. [1] Tower (Nasdaq: TSEM), an Israeli foundry, runs the wafer process; Semtech (Nasdaq: SMTC) designs the amplifiers and equalizers built on it and will invest to hold capacity in all three regions. [1] "Connectivity is now a primary factor in how far AI systems can scale," chief executive Hong Hou said. [1] [Tower's shares closed up 2.6% that day](https://www.stocktitan.net/news/TSEM/tower-semiconductor-announces-third-quarter-2026-financial-results-3l8xi7muvulc.html). [4]

## A 2030 target with booked demand under it

At its October 15 analyst day, Semtech lifted its fiscal third-quarter outlook to $417.5 million of net sales and $1.14 of adjusted earnings per share, from $410 million and $1.05. [2] Its fiscal year ends in January, so this is the quarter now closing. The 2030 framework sets $3.2 billion of sales, $2.1 billion of it from data centers growing 75% a year; blended growth is 38%, with LoRa, its slower internet-of-things radio line, at 30%. [2] The filing labels the 2030 figures targets and goals, not guidance. [2]

Under it, the base is contracted: [data-center revenue hit a record $100 million in the July quarter](https://www.sec.gov/Archives/edgar/data/88941/000008894126000028/smtc-07262026x8k991.htm), up 91% year over year and guided up another 45% this quarter, and management expects $475 million of it this fiscal year and $1 billion the next. [5][6] The backlog is fully booked through fiscal 2027 and already covers more than 70% of the fiscal 2028 target. [5]

*Chart: **Data-center revenue: $475M this year, $1B next, $2.1B by 2030** Column chart of Semtech data center revenue targets: $475 million this fiscal year, $1 billion next, $2.1 billion by 2030.*

*Semtech's data-center revenue path from its October 15 analyst-day framework: $475 million in fiscal 2027, $1 billion in fiscal 2028 and $2.1 billion by 2030, growing 75% a year. All three are management targets, not reported figures. Sources: Semtech Form 8-K, October 15, 2026; Zacks Investment Research. [2][5]*

*Chart: **Ten straight quarters of rising sales, and the raised guide steps the line to $417.5M** Line chart of Semtech quarterly net sales rising steadily from $206 million to a record $341.9 million, with a dashed guided point at $417.5 million.*

*Semtech quarterly net sales in US$ millions from its SEC filings. Labels are fiscal quarters, tagged with the calendar year in which each fiscal year began (fiscal 2027 began in January 2026). The dashed final point is the October 15 8-K guidance midpoint for the October-ending fiscal Q3 2027, an estimate, not a report. [2][7]*

## The multiple did the falling

[Sales have risen ten straight quarters to the July quarter's record $341.9 million](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0000088941), reported in August, and the new guide sits 22% above it. [7][8] The stock slid nearly 17% intraday anyway, closing at 97 times earnings and a $13.7 billion market value, [after a year that ran from $60.28 to $201.99](https://www.msn.com/en-us/news/other/semtech-stock-rebounds-as-wall-street-turns-focus-to-near-term-earnings-targets/ar-AA2enHzs). [3][9][10]

The day turned on one question: can 38% blended growth carry 97 times earnings. Traders said no, and MACOM, a rival in analog connectivity, [fell more than 10% in sympathy before closing down 6.5%](https://seekingalpha.com/news/4653550-semtech-tumbles-as-analyst-day-comments-spook-investors). [9][10] Analysts at BMO Capital said yes, [raising their target from $155 to $230](https://www.ad-hoc-news.de/boerse/news/nebenwerte/bmo-lifts-target-to-usd-230-00-for-semtech-stock/70332895) the same week. [10] The company ended the week with reserved capacity and a booked backlog; the market compressed the multiple, and the stock slipped again Friday to $141.03. [6]

## The supplier reports first

Tower posts third-quarter results with fourth-quarter guidance on November 2, the first outside reading on whether the reservation is pulling wafers through the foundry. [4] Semtech's own raised quarter closes at the end of October, with the report to follow and no date posted as of Friday. [7] The tell either way is whether data-center revenue keeps compounding above that 38% blended curve.

## Takeaway

Semtech reserved silicon-germanium wafer capacity at Tower and raised guidance, but at 97 times earnings the market read the numbers as already priced in; Tower's November 2 results and Semtech's data-center compounding are the next checks.
