AI Data Center Ambitions And Margin Pressures Will Restrain Long Term Upside

About MediaTek

MediaTek designs and supplies semiconductor solutions for smartphones, connected devices, automotive systems and data center customers.

What are the underlying business or industry changes driving this perspective?

• MediaTek is targeting at least a 10% to 15% share of a data center ASIC market that management now sizes at about US$50b by 2028. Any slowdown in hyperscaler AI capital expenditure or a smaller realized market could leave AI cloud revenues well below the US$1b in 2026 and the multiple billions discussed for 2027, which would weigh on revenue growth and scale benefits.
• The company is committing heavily to advanced process technologies, including 2 nanometer tape outs and complex 3.5D packaging. If end demand for AI computing and edge AI devices matures more slowly, that rising cost base could pressure gross margin and operating margin for longer than investors expect.
• Management is reallocating R&D and talent toward data center technologies and high speed interconnect IP while keeping R&D as a percentage of sales roughly flat or slightly lower. If AI ASIC projects or GB10 follow ons do not convert into the anticipated revenue scale, this shift could dilute returns on R&D and limit earnings growth.
• Flagship smartphone SoCs and AI smartphones are a key revenue driver, but management acknowledges that these products currently carry lower gross margin than the group average and rely on higher pricing to offset rising foundry and component costs. Intense competition or weaker AI phone demand could drag on net margins even if unit volumes hold up.
• The group is planning for tight leading edge capacity and higher wafer costs by trying to pass on price increases and prioritizing higher value segments such as automotive eCockpit and premium AI devices. If customers resist those price moves or face their own cost constraints, revenue mix could tilt toward lower margin products and keep net profit margin under pressure.

Assumptions

How have these above catalysts been quantified?

• This narrative explores a more pessimistic perspective on MediaTek compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts.
• The bearish analysts are assuming MediaTek's revenue will grow by 20.7% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from 16.9% today to 24.6% in 3 years time.
• The bearish analysts expect earnings to reach NT$256.4 billion (and earnings per share of NT$159.8) by about July 2029, up from NT$100.1 billion today. However, there is some disagreement amongst the analysts with the more bullish ones expecting earnings as high as NT$790.1 billion.
• In order for the above numbers to justify the price target of the more bearish analyst cohort, the company would need to trade at a PE ratio of 14.4x on those 2029 earnings, down from 59.0x today. This future PE is lower than the current PE for the TW Semiconductor industry at 47.7x.
• The bearish analysts expect the number of shares outstanding to grow by 0.14% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 9.67%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• MediaTek is already seeing AI driven demand across cloud and edge, including better than expected Dimensity 9500 uptake and GB10 moving into mass production, which could support revenue across multiple businesses over several years and help sustain earnings.
• Management describes the company as one of the few able to keep investing in advanced nodes such as 2 nanometer and complex 3.5D packaging, and successful early tape outs at TSMC could position MediaTek to win more high value designs that support gross margin and operating margin over time.
• The push into data center ASICs has already produced a first AI accelerated project that management expects to generate US$1b of cloud ASIC revenue in 2026 and multiple billions in 2027, and follow on projects plus a targeted 10% to 15% share of a US$50b ASIC market could lift long run revenue and operating profit.
• Flagship smartphone, Smart Edge and automotive businesses are all described as growing in U.S. dollar terms, with premium smartphone revenue targeted at more than US$3b in 2025 and auto revenue expected to more than double year over year in the fourth quarter, which could support group revenue growth and provide leverage to net profit margin as scale increases.

Valuation

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

• The assumed bearish price target for MediaTek is NT$1751.0, which represents up to two standard deviations below the consensus price target of NT$4841.78. This valuation is based on what can be assumed as the expectations of MediaTek's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of NT$10000.0, and the most bearish reporting a price target of just NT$1751.0.
• In order for you to agree with the more bearish analyst cohort, you'd need to believe that by 2029, revenues will be NT$1041.6 billion, earnings will come to NT$256.4 billion, and it would be trading on a PE ratio of 14.4x, assuming you use a discount rate of 9.7%.
• Given the current share price of NT$3700.0, the analyst price target of NT$1751.0 is 111.3% lower. Despite analysts expecting the underlying business to improve, they seem to believe the market's expectations are too high.
• 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.
