SoftBank (TSE:9434) Valuation Check as Shares Drift Higher After Strong Multi‑Year Returns

Simply Wall St·12/19/2025 14:24:17
Listen to the news

SoftBank (TSE:9434) has been drifting slightly higher this week, and with the stock still down over the past 3 months despite strong multi year returns, investors are revisiting the telecom giant’s valuation.

See our latest analysis for SoftBank.

At ¥217.8 per share, SoftBank’s recent drift lower follows a solid run, with an 11 percent year to date share price return and a 5 year total shareholder return of 117.41 percent, suggesting longer term momentum is still very much intact.

If SoftBank’s trajectory has you thinking about what else might be setting up for the next leg higher, now is a good time to explore fast growing stocks with high insider ownership.

With shares still trading at a discount to analyst targets and our estimate of intrinsic value despite steady earnings growth, the key question now is whether SoftBank is genuinely undervalued or whether the market has already priced in its next leg of growth.

Most Popular Narrative Narrative: 7.3% Undervalued

SoftBank’s most followed narrative pegs fair value at ¥234.93 per share, a moderate premium to the ¥217.8 last close, framing a measured upside case.

Strategic investment in domestic semiconductor initiatives (e.g., Rapidus) and collaborations with global technology leaders (e.g., NVIDIA) are likely to strengthen Japan's self-sufficiency in next-gen computing, supporting sustained long-term growth in SoftBank's technology and telecom portfolio and reducing future earnings volatility tied to supply chain/geopolitical risks.

Curious how steady revenue growth, rising margins and a lower future earnings multiple can still point to upside from here? The full narrative lays out the surprisingly ambitious financial path behind that conclusion, including how long term earnings power is modeled and why a modest discount rate still supports a higher fair value. Want to see the exact assumptions that make this valuation tick?

Result: Fair Value of ¥234.93 (UNDERVALUED)
