With the headline numbers in place, the next step is to assess how these results align with widely followed growth and risk narratives around Keysight, and where the earnings story might challenge those views.

Margins Strengthen Alongside US$5.7b Trailing Revenue

• Over the last twelve months, Keysight generated about US$5.7b in revenue and US$981 million in net income, which works out to a 17.3% net margin compared with 12.2% a year earlier.
• Consensus narrative points to higher software and services exposure as a key support for margins. The recent 60.6% earnings growth alongside the 17.3% margin fits that view, but the slower forecast revenue growth of about 8.5% per year than the broader US market limits how confident investors might be that this margin level can consistently support long term earnings growth.
  • Analysts expecting around 13% annual earnings growth are effectively counting on the current profit per dollar of sales staying healthy even as revenue grows at a mid single to high single digit pace.
  • At the same time, the past five year earnings trend shows a 5.2% annual decline, which is a reminder that the latest margin profile is only one part of a longer earnings story that has not been in a straight line.

Premium Valuation vs 59.8x P/E And DCF Fair Value

• Keysight is trading around US$342 with a trailing P/E of about 59.8x, compared with an industry average near 30.1x and peer average near 48.6x, while the DCF fair value in the data is US$223.38.
• Bears argue that paying such a premium multiple leaves little room for error. The combination of a 59.8x P/E and a share price above the US$223.38 DCF fair value supports that caution, even though earnings grew 60.6% over the last year.
  • The gap between the current price of roughly US$342 and analyst target level of US$371.46 in the dataset is narrower than the gap to the DCF fair value, so different valuation lenses point in different directions on upside potential.
  • Forecast earnings growth of about 13% per year with revenue at roughly 8.5% per year is solid, but bears focus on the five year earnings decline of 5.2% annually as evidence that the high multiple is grounded more in recent momentum than in a long multi year track record.

Skeptics watching the high P/E and DCF gap often want more detail on the cautious case before deciding how much risk they are taking on 🐻 Keysight Technologies Bear Case.

Fast EPS Recovery Tests The Bullish Growth Story

• EPS moved from a loss of US$0.42 in Q4 2024 to US$0.98 in Q1 2025 and then to US$1.63 by Q1 2026, alongside quarterly revenue rising from US$1.29b to US$1.6b over the same period.
• Bulls highlight this sharp EPS recovery and the 60.6% year over year earnings growth as evidence that Keysight can support forecasts around 13% annual earnings growth. The trailing twelve month EPS of US$5.71 with US$5.7b of revenue strongly supports that optimism, even though the longer five year trend still shows earnings declining 5.2% per year.
  • The move from US$611 million in trailing net income at the start of the period to US$981 million is consistent with the idea that profit drivers such as AI test demand and higher margin software can keep pulling EPS higher from here.
  • However, the fact that revenue in the trailing twelve month data rose from US$5.0b to US$5.7b while analyst growth forecasts sit below broader US market levels is a reminder that the bullish view leans heavily on continued margin strength rather than an expectation of very fast top line expansion.
