Net Margin Slips From 42.7% To 24.6%

• Over the last 12 months, net profit margin sat at 24.6%, compared with 42.7% the year before, while trailing 12 month earnings moved from US$59.2 million a year ago to US$23.3 million now.
• What stands out for a bearish narrative that focuses on worsening profitability is that margins and earnings have both weakened over the year. At the same time, trailing 12 month revenue of about US$94.6 million and five year earnings growth of 2.7% a year mean the business is still producing profit overall, which partly offsets the concern about the recent drop in margin.
  • Critics highlight that quarterly net income swung from US$45.8 million in Q4 2024 to a loss of US$5.4 million in Q4 2025, which lines up with the margin compression story.
  • At the same time, the trailing 12 month net income of US$23.3 million and positive five year growth rate show the earnings picture is not purely about recent losses.

Lumpy Revenue, From US$81.5m To US$3.8m

• Over the last six reported quarters, revenue has ranged from about US$81.5 million in Q4 2024 and US$81.1 million in Q2 2025 down to US$3.8 million in Q4 2025, with trailing 12 month revenue at roughly US$94.6 million.
• Bears often worry that such swings make the business hard to rely on. Yet the trailing 12 month profit of US$23.3 million and basic EPS of US$0.33 over that period show that even with low revenue in the latest quarter, the last year as a whole remained profitable.
  • Quarterly net income moved from US$35.5 million in Q2 2025 to a loss of US$6.4 million in Q3 2025 and a loss of US$5.4 million in Q4 2025, so the weak finish to the year contrasts with earlier profitability.
  • That contrast between strong quarters and recent losses is exactly what beginners should watch, because it highlights how much the business can depend on a few high revenue periods.

P/E Of 16.8x And 58% DCF Gap

• The trailing P/E of 16.8x sits below the US Pharmaceuticals industry average of 18x and the peer average of 43.5x, while the current share price of about US$5.48 is roughly 58% below a DCF fair value of about US$13.09.
• Supporters of a bullish view point out that the combination of a lower P/E than both industry and peers, plus a market price around US$5.48 compared with a DCF fair value of about US$13.09, heavily supports the idea that the stock looks inexpensive even after a year where earnings growth was negative.
  • Backing that up, trailing 12 month earnings of US$23.3 million and a five year earnings growth rate of 2.7% a year sit alongside a classification of earnings quality as high over the period.
  • What may surprise you is that this valuation picture comes despite margin compression from 42.7% to 24.6%, so the numbers are not relying on peak profitability to look comparatively cheap.
