With the latest numbers on the table, the next step is to see how this earnings story lines up with the dominant narratives around IES Holdings, and where those narratives might be challenged by the data.

TTM earnings growth outpaces revenue

• Over the last twelve months, total revenue moved from about US$3.0b to US$3.5b while EPS over the same period went from US$10.89 to US$17.04, so earnings have risen faster than sales.
• What stands out for a bullish view is that earnings growth of 54.8% year over year and a five year average of 45.6% a year sit on top of this revenue step up. This supports the idea of stronger earnings power, yet it also raises the bar for bulls to show that this gap between earnings and revenue growth can stay in place as the business scales.
  • The trailing twelve month net income excluding extra items is US$338.9 million on US$3.5b of revenue, compared with US$218.9 million on US$3.0b a year earlier, so profit has moved ahead by more than US$100 million on roughly US$500 million of extra sales.
  • Quarter by quarter, net income excluding extra items went from US$55.2 million in Q1 2025 to US$91.0 million in Q1 2026, which lines up with the bullish view that profitability has strengthened, even if future growth rates moderate from recent levels.

Margins improve to 9.7% on TTM basis

• The trailing net profit margin sits at 9.7% compared with 7.3% a year ago, and Q1 2026 net income of US$91.0 million on US$871.0 million of revenue is consistent with that higher margin profile.
• Supporters of a bullish narrative point to these margin levels and describe past earnings as high quality. The current numbers give them concrete backing while also creating a test of how long that quality label holds if growth becomes more dependent on maintaining close to a 10% margin.
  • Over the last five reported quarters, net income excluding extra items rose from US$62.1 million in Q4 2024 to US$100.5 million in Q4 2025 and then US$91.0 million in Q1 2026, so profitability has stayed well ahead of the US$55.2 million level from Q1 2025.
  • EPS followed a similar pattern, moving from US$3.10 in Q4 2024 to US$5.06 in Q4 2025 and US$4.58 in Q1 2026, which fits a bullish claim that the business is earning more per share across different recent periods, not just in a single spike.

Valuation signals send a mixed message

• The current share price of US$655.64 sits well above the DCF fair value of about US$248.92, while the trailing P/E of 38.6x is a little below peers at 39.1x and below the US Construction industry average of 46.3x.
• Investors taking a more cautious, valuation first stance are likely to focus on this split, because the DCF gap suggests the price is above that modelled value even as the P/E ratio screens slightly cheaper than peers. The numbers leave room for bullish arguments about relative value and strong growth as well as more bearish questions about paying far above the DCF fair value for those traits.
  • The forecast earnings growth rate of about 17.4% a year and revenue growth of about 13.6% a year are often used by bulls to justify paying up, yet the DCF output still points to a lower figure than the current share price.
  • At the same time, the P/E sitting under both peer and industry averages can be used by bulls to argue the stock is not stretched compared with other construction names, even though absolute price compared with DCF fair value gives a very different signal.
