TSEM: RF Connectivity And SiPho Execution Will Reshape Earnings Mix By 2027

The updated analyst price target for Tower Semiconductor moves from about US$134 to roughly US$136, as analysts point to stronger RF Infrastructure connectivity positioning and SiPho demand commentary from recent research as key supports for modestly higher fair value, revenue growth, and future P/E assumptions, despite slightly softer profit margin inputs.

Analyst Commentary

Recent research updates on Tower Semiconductor cluster around higher price targets and a stronger narrative for RF Infrastructure and SiPho, but there are still open questions that matter for execution and valuation risk.

Bullish Takeaways

Bullish analysts highlight Tower's position in RF Infrastructure connectivity as a key support for higher fair value, viewing this segment as a core driver for revenue mix and earnings power over the next several years.
Some expect the RF Infrastructure segment to account for 45% or more of total revenue by 2027. If achieved, this could justify higher long term earnings assumptions and help support the current P/E framework used in their models.
Updated research cites SiPho commentary pointing to what is described as "robust acceleration" in Q4 and beyond, which analysts view as supportive for growth in high value connectivity and data center oriented applications.
Across the bull camp, higher price targets are tied to management access and recent earnings commentary, which analysts treat as reinforcing confidence in execution on the RF and SiPho roadmaps.

Bearish Takeaways

Even with higher price targets, some bearish analysts maintain more neutral stock ratings, which suggests they see execution risk around turning RF Infrastructure and SiPho commentary into consistent, high quality earnings.
The expectation that RF Infrastructure could reach 45% or more of total revenue and that annualized EPS could meet or exceed US$5.50 exiting 2027 introduces a high bar. This leaves less room for missteps on customer demand, pricing, or capacity utilization.
References to "robust acceleration" in SiPho are based on company commentary rather than a long track record, so more cautious analysts may treat these forecasts as sensitive to changes in end market demand.
With multiple analysts already lifting targets, incremental upside from further estimate revisions may become harder to justify without clearer evidence on margins, capital intensity, and long term cash generation.

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.
