TSEM: RF And SiPho Momentum Will Redefine Earnings Mix By 2027

Analysts have lifted their price target on Tower Semiconductor by $5, to $129, citing stronger long term earnings power driven by accelerating RF Infrastructure and SiPho demand, as reflected in recent post earnings estimate revisions.

Analyst Commentary

Bullish Takeaways

Bullish analysts point to stronger than expected Q3 results as evidence that Tower is executing well against its long term growth strategy, which they see as justifying higher price targets and upward estimate revisions.
Expectations that RF Infrastructure could account for 45 percent or more of total revenue by 2027 underpin a view that the business mix is shifting toward higher growth, higher visibility segments that support premium valuation multiples.
Street models incorporating annualized EPS of at least $5.50 exiting 2027 suggest meaningful earnings expansion, with some upside if RF demand and utilization trends remain favorable.
Commentary on SiPho points to robust acceleration in Q4 and beyond, reinforcing the narrative that Tower is well positioned in structural growth markets tied to data center and high speed connectivity, which could support multiple expansion.

Bearish Takeaways

Bearish analysts, while raising targets, maintain more neutral ratings. This signals concerns that a sizable portion of the near term upside is already reflected in the share price.
Execution risk around achieving a 45 percent RF Infrastructure revenue contribution by 2027 is seen as a key watch point, as delays or softer demand could pressure growth expectations and valuation.
SiPho driven upgrades are partly contingent on sustained end market strength in networking and AI infrastructure, leaving earnings vulnerable if demand normalizes faster than anticipated.
Some models embed ambitious margin and utilization assumptions into 2027 EPS targets, creating downside risk to estimates if supply chain, pricing, or capex efficiency fall short of current projections.

About Tower Semiconductor

An independent semiconductor foundry, provides technology, development, and process platforms for integrated circuits in the United States, Japan, rest of Asia, and Europe.What are the underlying business or industry changes driving this perspective?

Accelerating demand for data center, AI, and 5G infrastructure is driving increased adoption of Tower's Silicon Photonics and Silicon Germanium solutions, with meaningful capacity expansions and customer onboarding supporting strong revenue growth and higher margin product mix over the next several years.
The rapid ramp-up in silicon photonics shipments-including expansion from transmit-only to both transmit and receive functions, higher bandwidth modules (up to 1.6T with 3.2T on the roadmap), and adoption by Tier 1 customers-positions Tower to further penetrate the growing optical transceiver market, supporting future revenue acceleration and increased average selling prices.
Broadening partnerships with leading global customers (across U.S., Japan, Israel, and Europe) and the company's diversified worldwide manufacturing footprint enable Tower to capture market share as industries continue to digitize and regionalize supply chains, contributing to more stable recurring revenues and de-risked earnings outlook.
Tower's ongoing strategic CapEx investments in high-demand specialty platforms (SiPho, SiGe, RF, and advanced power management), with capacity coming online in 2025/26, are expected to drive significant operating leverage and margin improvement as fab utilization rises and high-value products scale.
The proliferation of IoT, edge computing, and electrification across industrial, automotive, and consumer sectors strengthens multiyear demand for analog, mixed-signal, and specialty nodes-core Tower offerings-supporting a sustained long-term revenue growth trajectory and resilience in earnings.

Assumptions

How have these above catalysts been quantified?

Analysts are assuming Tower Semiconductor's revenue will grow by 15.6% annually over the next 3 years.
Analysts assume that profit margins will increase from 13.2% today to 20.5% in 3 years time.
Analysts expect earnings to reach $469.8 million (and earnings per share of $3.16) by about September 2028, up from $196.5 million today.
In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 23.8x on those 2028 earnings, down from 36.8x today. This future PE is lower than the current PE for the US Semiconductor industry at 33.5x.
Analysts expect the number of shares outstanding to grow by 0.52% per year for the next 3 years.
To value all of this in today's terms, we will use a discount rate of 13.01%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

Tower's heavy capital expenditures for capacity expansion (over $1.15 billion in CapEx committed through 2026) may outpace actual long-term demand if industry trends change or customer forecasts do not materialize, potentially leading to underutilized fabs and weakened return on investment, which could negatively impact both net margins and free cash flow.
The company's strong current growth is heavily concentrated in Silicon Photonics (SiPho) and Silicon Germanium (SiGe) for optical transceivers, a niche specialty foundry segment; if industry technology shifts (e.g., rapid co-packaged optics adoption, disruption from competing materials like indium phosphide, or a move away from current process nodes) occur faster than expected, Tower may be exposed to obsolescence risk, resulting in long-term revenue decline.
While management highlights customer diversification and Tier 1 relationships, the dependence on a small number of high-growth customers in infrastructure and mobile segments increases customer concentration risk-any loss, reduction, or migration of these customers to local or larger foundry competitors could sharply reduce revenues and earnings.
Tower's manufacturing footprint spans Israel, the US, Japan, and Italy, but ongoing geopolitical risks (e.g., escalation in Israel, US-China trade tensions, or increased regionalization of semiconductor supply chains) could disrupt operations, limit export opportunities, or drive customers toward domestic fabs, creating revenue and margin volatility.
The ongoing need for high CapEx, coupled with Tower's focus on mature/specialty process nodes rather than advanced leading-edge technology, may expose the company to price competition and margin compression as larger mega-foundries (like TSMC and Samsung) expand their specialty offerings, and as cost pressure from new entrants, especially in Asia, increases-potentially leading to long-term declines in net margins and market share.

Valuation

How have all the factors above been brought together to estimate a fair value?

The analysts have a consensus price target of $68.66 for Tower Semiconductor based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $80.0, and the most bearish reporting a price target of just $59.3.
In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $2.3 billion, earnings will come to $469.8 million, and it would be trading on a PE ratio of 23.8x, assuming you use a discount rate of 13.0%.
Given the current share price of $64.57, the analyst price target of $68.66 is 6.0% higher. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
