Daiichi Sankyo (TSE:4568) Valuation After Patent Win and New ENHERTU, DATROWAY Oncology Milestones
Daiichi Sankyo Company (TSE:4568) has just cleared a major legal hurdle while pushing deeper into oncology, with a U.S. appeals court invalidating a Seagen patent and fresh clinical momentum around ENHERTU and DATROWAY.
See our latest analysis for Daiichi Sankyo Company.
The mix of a cleared patent overhang and steady ENHERTU and DATROWAY news flow has not yet turned the tide. The share price has delivered a year-to-date return of negative 19.3 percent and a one-year total shareholder return of negative 21.38 percent, suggesting sentiment is still resetting rather than building sustained momentum.
If oncology innovation is on your radar after Daiichi Sankyo, this could be a good moment to explore other healthcare stocks that might fit your strategy.
With the legal overhang easing, oncology assets scaling and the stock still trading at a steep discount to analyst targets, the key question is whether Daiichi Sankyo is now mispriced value or whether markets already anticipate its next leg of growth.
Most Popular Narrative: 37.4% Undervalued
With Daiichi Sankyo last closing at ¥3,470 against a narrative fair value near ¥5,546, the valuation debate centers on how durable its oncology-led growth really is.
Pipeline depth in antibody-drug conjugates, supported by ongoing R&D investment and multiple upcoming pivotal data readouts and regulatory submissions for several major tumor types, positions the company to capture higher margin opportunities as precision medicine gains traction. This could further boost future net margins and earnings as secular demand for innovative targeted therapies increases.
Want to see the math behind this gap? The narrative leans on accelerating oncology revenues, rising margins and a richer future earnings multiple. Curious which assumptions really move the fair value line.
Result: Fair Value of ¥5,546.47 (UNDERVALUED)

However, this upside case could be derailed if ENHERTU or DATROWAY stumble on safety, competition, or pricing pressure, undermining revenue concentration and margins.

Another Way to Look at Value
On earnings, Daiichi Sankyo does not look as cheap. The shares trade on roughly 23 times earnings versus about 15.3 times for the wider Japanese pharma sector, even though our fair ratio points closer to 29.5 times. That premium keeps the downside debate alive, especially if growth disappoints.
