Margins Under Pressure At 11.5%

• On a trailing basis, net income was US$206.1 million on US$1.79b of revenue, giving a net margin of 11.5% compared with 16.1% a year earlier.
• What stands out for a cautious, more bearish view is that trailing EPS slipped from 2.57 US$ to 2.00 US$ while revenue moved from US$1.59b to US$1.79b.
  • Critics highlight that net income only edged up from US$203.1 million to US$206.1 million even as revenue rose by over US$200 million, which lines up with the margin compression.
  • This tension between higher sales and lower trailing net margin is exactly the kind of pattern bears point to when questioning how efficiently new revenue is turning into profit.

Trailing Revenue Up 7.4% With Softer Profit

• Revenue on a trailing 12 month basis increased from US$1.59b to US$1.79b, a growth rate of about 7.4% per year, while trailing earnings declined and margin moved from 16.1% to 11.5%.
• Supporters with a more bullish tilt often focus on the five year earnings growth rate of about 20.1% per year and the 19.1% earnings growth forecast.
  • That longer term earnings growth profile sits beside the current 7.4% revenue growth and lower 11.5% margin, which suggests past profitability trends and the latest margin data are pulling in different directions.
  • This mix heavily supports the bullish case that the business model can still produce strong earnings growth, while the recent margin step down is a concrete metric bulls need to keep testing against those expectations.

P/E Of 22.9x And DCF Gap

• The stock trades on a P/E of 22.9x, below the US Software industry average of 29.3x and peer average of 40.1x, and the current US$46.65 share price sits below a DCF fair value of US$65.92 and below an analyst price target level of US$64.00.
• Consensus style thinking that ACI Worldwide offers potential value is strongly anchored in these gaps.
  • The discount to the DCF fair value of US$65.92 and to the US$64.00 analyst price target range sits alongside analysts’ indication of about 37.2% implied upside from the current US$46.65 price.
  • At the same time, the high debt flag and the margin move from 16.1% to 11.5% give concrete reasons for more cautious investors to question how quickly the share price might close that valuation gap.
