Is Keysight Technologies (KEYS) Overvalued or Undervalued? A Complete Valuation Analysis 2026

The short answer

Short answer: Keysight Technologies looks overvalued at current levels. Compared with the recent share price of $355.06, the current DCF output near $97.65 suggests Keysight Technologies is about 263.6% overvalued on these cash flow assumptions. Keysight Technologies is being valued in the context of a business with gross margin near 61.9%, which helps show what kind of operating model investors are paying for. The fair answer depends on whether the business can keep converting its current position into enough earnings, growth, and cash flow to justify the market price.

Why valuing this kind of technology company is more complex than it looks

Keysight Technologies operates in Hardware, Equipment & Parts. Companies in this part of the market are usually valued on a mix of current earnings, expected growth, margin durability, and cash generation.

The reason this matters is simple. Two companies can show similar headline multiples and still deserve very different valuations because their margins, cash conversion, and growth durability are not the same.

What the numbers tell us

The first thing to notice with Keysight is the gap between trailing and forward earnings valuation. Trailing P/E is near 72.5x while forward P/E is near 204.2x, which tells you the market is already underwriting a specific earnings path.

Keysight's forward P/E is not offering much relief versus the trailing multiple, so the market may still be paying up before the earnings improvement is fully visible.
Keysight's PEG ratio near 1.1x matters because it tests whether the earnings multiple is being balanced by a credible growth rate.
Keysight's price to sales multiple near 10.7x needs to be read beside revenue growth near 8.0%, because rich revenue multiples only hold up when growth quality stays intact.

What would make Keysight Technologies look cheaper or more expensive?

What would make it look cheaper

What would make it look expensive

Keysight would also look expensive if margins weakened but the stock kept the same quality premium.

Technology valuation context

The verdict
