TTM profit growth slows to 6.2%

• Over the last 12 months, profit growth is cited at 6.2%, compared with a five year earnings growth rate of 29.5% per year. The recent pace is well below the longer trend even though trailing 12 month net income excluding extra items is still US$1.9b on US$6.8b of revenue.
• What stands out for bullish investors is that this slower 6.2% one year earnings growth sits alongside earnings that are described as high quality. This creates a tension between:
  • Multi year strength, with that 29.5% annual earnings growth over five years pointing to a long track record of profit expansion.
  • The recent moderation, where the 6.2% trailing growth and a trailing net profit margin of 27.3% suggest the latest year has been less strong than that history.

Margins ease from 29.3% to 27.3%

• The data flags a trailing net profit margin of 27.3%, compared with 29.3% a year earlier, alongside trailing 12 month revenue of US$6.8b and net income excluding extra items of US$1.9b.
• Critics point to the margin slip as a bearish sign, and that concern lines up with other figures here, because:
  • One year earnings growth of 6.2% is lower than the 29.5% per year pace over five years, so the margin dip comes at the same time as slower profit growth.
  • Analyst forecasts in the dataset of about 9.95% annual earnings and revenue growth are also below the cited broader US market growth rates, which bears may read as a slower growth profile combined with slightly lower margins.

P/E of 33.2x and DCF gap

• Fortinet is trading on a trailing P/E of 33.2x at a share price of US$82.76, compared with a DCF fair value in the data of US$109.45 and a US Software industry average P/E of 26.9x, while the peer group average P/E is 50.9x.
• Supporters of the bullish view often highlight this valuation mix, and the numbers here give them specific talking points as well as some pushback, because:
  • The stock price is about 24.4% below the cited DCF fair value, which they may see as valuation headroom if the roughly 9.95% earnings growth forecasts are reached.
  • At the same time, the 33.2x P/E stands above the wider US Software industry average and follows a year where earnings growth was 6.2% and margins eased, which can limit how strong that bullish argument feels.
