Listen to the news

Agilent Technologies (A) just secured U.S. FDA approval for its PD-L1 IHC 22C3 pharmDx test in first line ovarian and related cancers, extending the assay’s use as a companion diagnostic for Merck’s Keytruda.

See our latest analysis for Agilent Technologies.

Agilent’s latest FDA approval and ongoing automation push come while the 1 month share price return of 9.9% decline and 3 year total shareholder return of 13.24% decline signal pressure on both short and long term performance, suggesting sentiment is still resetting rather than building momentum.

With Agilent shares down over the past year even as revenue and net income growth remain positive, is the recent FDA win and AI automation push an overlooked entry point, or is the market already pricing in future growth?

Most Popular Narrative: 25.8% Undervalued

Agilent Technologies closed at $125.81, while the most followed narrative anchors fair value at $169.67, framing the latest FDA win within a wider, long term thesis.

Strategic investments in higher margin recurring revenue streams including consumables, software, services, and digital platforms are gaining traction, with CrossLab and services delivering consistent mid single digit growth and high customer satisfaction, indicating further margin expansion and greater earnings stability in future periods.

Read the complete narrative.

Curious what supports a higher fair value when recent returns are under pressure? The narrative focuses on recurring revenue, margin expansion, and a richer earnings profile projected a few years out.

Result: Fair Value of $169.67 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, this hinges on tariff costs and supply chain reshuffling not biting harder than expected, and it also depends on lab customers not stretching out replacement cycles longer than analysts assume.

Another View: P/E And Fair Ratio Send A Different Signal

Analysts see upside from today’s $125.81 price, yet Agilent trades on a 27.3x P/E versus a fair ratio of 24.4x, the US Life Sciences industry at 35.2x and peers at 30.8x. The stock therefore appears cheaper than its sector but richer than its own fair ratio, raising the question of whether you see more valuation risk or opportunity here.
