Net Margin Near 48% On Trailing Basis

• On the trailing twelve month numbers, 3SBio reports net income of ¥8.5b on ¥17.7b of revenue, which translates to a 47.9% net margin compared with 23% in the prior year period.
• What stands out for a more bullish angle is that this very large earnings jump of 305.8% over the past year sits alongside that 47.9% margin, which heavily supports the idea that recent profitability is not just about top line size but also about how much of each yuan is being kept as profit.
  • Over the last twelve months, net income reached ¥8.5b on ¥17.7b of revenue, while five year annualized earnings growth is reported at 32.3% per year.
  • This combination of strong reported margin and multi year earnings growth gives bullish investors concrete figures to point to when they argue that the business model has been earning solid returns over this period.

Valuation Signals Look Compressed

• The shares trade on a P/E of 5.9x compared with 38.1x for the Asian Biotechs industry and 65.3x for peers. The current price of HK$22.64 is also well below the cited DCF fair value of HK$54.87.
• Critics highlight that even with this low P/E and the gap to the DCF fair value, the same dataset flags that revenue is forecast to decline by 21.2% per year and earnings by 53.4% per year over the next three years, so the compressed multiple may be reflecting those projections rather than ignoring them.
  • The forecasted earnings contraction contrasts sharply with the trailing 305.8% earnings growth, which means bearish investors can argue that the recent twelve month strength is not what the forward numbers are built on.
  • Because the stock trades around 58.7% below the DCF fair value estimate while carrying those decline forecasts, both bulls and bears can find support in the same set of figures when they debate whether the current valuation is attractive.

Half Year Profitability Outpaces Revenue

• In 2025 H1, revenue of ¥4,355.5m sits slightly below the ¥4,718.5m reported in 2024 H2, yet net income excluding extra items is ¥1,358.2m compared with ¥1,000.4m in 2024 H2 and ¥1,089.9m in 2024 H1.
• What is surprising for a more bearish reading is that the main flagged risk is the forecast decline in earnings and revenue, yet within the last three half year periods net income excluding extra items has moved from ¥1,089.9m to ¥1,000.4m to ¥1,358.2m while basic EPS has moved from ¥0.45 to ¥0.41 to ¥0.57. This gives bears a clear tension between the historical profit pattern and the forward projections they are relying on.
  • Over the same halves, revenue has stayed in a fairly tight band around ¥4.4b to ¥4.7b, while the trailing period as a whole sums to ¥17.7b, showing that the stronger trailing margin is being measured on a revenue base that has not surged.
  • This mix of steady recent revenue, rising trailing margin to 47.9% and very large reported earnings growth against forecasts of multi year decline is exactly the kind of data gap cautious investors point to when they argue that the recent run rate may not persist.
