SoftBank stock has delivered an 84.3% return over the past 5 years, yet today’s valuation picture is split, with a Discounted Cash Flow (DCF) intrinsic value estimate pointing to around 11.1% upside while market based multiples suggest the shares are trading on the expensive side. That tension, combined with a low overall value score, makes the current price less straightforward than the long term return might suggest.
Over 5 years, SoftBank has returned 84.3%, which puts recent short term ups and downs into context and makes the current valuation debate more important for new capital.
Future cash flow from its telecom operations and related services can support the DCF view of upside, but any pressure on margins or higher capital needs may weigh on the market’s willingness to pay a premium multiple.
Across Simply Wall St’s broader checks, SoftBank scores 1 out of 6 on value, which signals the stock is not a clear bargain when looking beyond the intrinsic value model.
The issue now is whether SoftBank’s recent 5 year run and mixed valuation signals leave enough potential upside to compensate for the risks implied by the low value score.
Find out why SoftBank’s 1.4% return over the last year is lagging behind its peers.
Is SoftBank a Bargain on Cash Flow?
The Discounted Cash Flow (DCF) model estimates what SoftBank might be worth today based on the cash it is expected to generate for shareholders. For the latest twelve months, SoftBank reports free cash flow of about ¥724.1b, and the model assumes these cash flows generally grow before easing back over time as the business matures.
On these assumptions, the DCF model points to an intrinsic value of around ¥237.70 per share. Compared with the current share price, that implies SoftBank stock screens about 11.1% undervalued on a pure cash flow basis, even after factoring in a step down to lower projected free cash flow further out in the forecast period.
Overall, the DCF work suggests SoftBank looks undervalued relative to the cash the business is expected to generate.
Our Discounted Cash Flow (DCF) analysis suggests SoftBank is undervalued by 11.1%. Track this in your watchlist or portfolio, or discover 19 more high quality undervalued stocks.

Has SoftBank Run Too Far on Earnings?
Story Continues
P/E is a useful cross check for SoftBank because earnings are a core focus for many telecom investors. SoftBank trades on a P/E of about 18.7x, which sits above the Wireless Telecom industry average of roughly 15.5x and also above the peer group average of about 15.0x.
The fair P/E ratio implied by Simply Wall St’s model is around 14.0x, which is lower than both the current multiple and the industry benchmark. That gap suggests the market is paying a premium for SoftBank relative to what the model views as reasonable given its profile, even though the DCF work indicates potential upside on cash flows.
On earnings, SoftBank stock currently screens as overvalued, trading at a richer P/E multiple than both peers and the model’s fair ratio.

The Bottom Line
SoftBank sits in a grey zone, with the Discounted Cash Flow (DCF) work pointing to some intrinsic value upside while the market multiples say the stock is already trading at a premium. That split reflects different sensitivities: the DCF leans on how reliably SoftBank can convert its telecom cash flows over time, while the P/E view leans on how much investors are willing to pay for that profile versus peers. Broader valuation checks remain weak, so the key debate from here is whether SoftBank can sustain cash generation strongly enough to justify the richer multiple rather than drifting closer to the model’s fair ratio.
