• Earlier this year, ON Semiconductor reported Q4 2025 non-GAAP EPS of US$0.64, generated record free cash flow, approved a US$6.00 billion buyback, and introduced vertical GaN power semiconductors targeting AI data centers and electric vehicles.
• The combination of strong cash generation, a very large repurchase plan, and new GaN products aimed at high-growth power markets has sharpened investor focus on how ON Semiconductor balances capital returns with long-term technology investment.
• We’ll now examine how ON Semiconductor’s record free cash flow and very large buyback authorization may influence its existing investment narrative.

Find 49 companies with promising cash flow potential yet trading below their fair value.

ON Semiconductor Investment Narrative Recap

To own ON Semiconductor, you need to believe its power and sensing portfolio can convert EV, AI data center, and industrial electrification demand into durable free cash flow. The recent Q4 2025 print, record free cash generation, and vertical GaN launch support that cash story, but they do not remove the near term risk around utilization, legacy revenue exits, and exposure to cyclical auto demand, which still look like the key swing factors for the stock.

The US$6.00 billion repurchase authorization, combined with ongoing buyback execution in early 2026, is the most relevant announcement here. It reinforces how much management is leaning on capital returns at a time when earnings have been pressured by one off items and portfolio reshaping. For many investors, the critical question is whether this level of buybacks complements or competes with the investment needed to keep ON ahead in SiC, GaN, and AI focused power products.

Yet behind the strong cash generation and big buyback, investors should be aware of ON’s rising geopolitical and regulatory exposure...

ON Semiconductor's narrative projects $8.1 billion revenue and $2.2 billion earnings by 2029. This requires 10.3% yearly revenue growth and an earnings increase of about $1.6 billion from $573.7 million today.

Uncover how ON Semiconductor's forecasts yield a $103.97 fair value, a 11% downside to its current price.

Exploring Other Perspectives

While recent results highlight cash strength and buybacks, the lowest analysts took a tougher view, assuming revenue of about US$7.5 billion and earnings near US$1.7 billion by 2029, which may look ambitious if supply chain localization and tariff pressures raise costs faster than expected.
