Can SMS (TSE:2175) Stay Cheap After A 69% Run?

Simply Wall St·08/17/2026 10:21:06
Listen to the news

SMS stock has delivered a strong 68.5% return year to date, while both the Discounted Cash Flow (DCF) intrinsic value estimate and the market multiples currently point to the shares trading on the cheap side rather than at a premium.

  • The 68.5% gain year to date suggests SMS has already re-rated sharply. However, valuation models still see room between the current share price and the intrinsic value estimate.
  • Future cash flow growth and the timing of that cash generation can support the current valuation, while any setback in execution or weaker profitability would quickly test how much undervaluation is really in the price.
  • On Simply Wall St's broader checks, SMS screens as undervalued in 3 of 6 areas. This is a mixed picture rather than a clear bargain or clear overvaluation, and that is captured in its 3 out of 6 value score.

The issue now is whether SMS's current share price already reflects most of that perceived undervaluation or if investors are still being offered a genuine discount to intrinsic value.

Find out why SMS' 44.0% return over the last year is lagging behind its peers.

Is SMS Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model used here values SMS by projecting future free cash flows and discounting them back to today. For SMS, the latest twelve month free cash flow is about ¥4.7b, and the model assumes these cash flows continue to grow rather than contract over time.

On that basis, the 2 Stage Free Cash Flow to Equity model points to an estimated intrinsic value of about ¥3,396 per share. Compared with the current share price, this implies roughly a 33.0% discount. That gap suggests the market is pricing SMS below what its current and projected cash generation support, although the result remains sensitive to how these future cash flows actually develop.

Overall, the DCF analysis indicates that SMS currently appears undervalued relative to its projected cash flows.

Is SMS a Bargain on Sales?

The P/S ratio is a useful cross check for SMS because revenue is less affected by accounting choices than earnings. SMS currently trades on a P/S of about 2.8x, compared with an industry average of roughly 0.9x and a peer group average near 2.5x.

The valuation model that adjusts for SMS's size, margins and risks suggests a fair P/S closer to 4.2x. That level is above both the current multiple and the peer and industry benchmarks. The gap indicates the market is assigning a lower value to each yen of SMS revenue than this tailored fair value estimate, even after the strong year to date share price move.

On this P/S measure, SMS stock appears undervalued relative to what the model indicates would be a fair revenue multiple.

The Bottom Line

For SMS, both the Discounted Cash Flow (DCF) intrinsic value estimate and the revenue multiple work in the same direction and point to an undervalued stock rather than a stretched one. The broader checks remain mixed though, so the case is not a straightforward bargain and still rests on how SMS converts its current business into sustained cash generation.

The real dividing line between the bull and bear views is whether SMS can deliver the cash flows and profitability that the intrinsic value model assumes. If that execution holds up, today’s discount can appear justified. If it slips, the perceived undervaluation can close quickly.
