Is Datadog (DDOG) A Bargain After Soft Guidance Hit Its Valuation?

Why Datadog’s strong quarter rattled the stock

Datadog (DDOG) beat third quarter expectations on both earnings and revenue, then unsettled investors with fourth quarter guidance that pointed to roughly flat sales and softer operating margins despite solid customer metrics.

The guidance spelled out revenue of US$1.19b to US$1.20b for the coming quarter and US$4.515b to US$4.525b for 2026 as a whole. That outlook framed the entire market reaction more than the headline beat did.

That cautious outlook hit a stock that had already pulled back sharply, with a 1 day share price return of down 7.48% and a 7 day move of down 25.79%. This comes even though the year to date share price return is up 30.52% and the 3 year total shareholder return is up 68.45%, so recent momentum is clearly fading after a strong multi year run.

Recent headlines around Datadog now focus less on the Q3 beat and more on how flat near term guidance, heavier investment in AI tools like Scout 1.0 and Bits, and concentration in large customers are feeding into a 30 day share price return of down 35.65% and a 1 year total shareholder return of down 8.70% as investors reassess both growth potential and risk.

Datadog appears to be a high quality platform business based on this quarter, yet the share price has dropped sharply. Has the recent reset finally left the stock at a sensible valuation?

Most Popular Narrative: 40.3% Undervalued

Datadog last closed at $174.60 while the most followed narrative pegs fair value at about $292 per share. The story hinges on whether that gap is justified by AI and platform economics or closed by execution risk and customer concentration.

Customer movement toward autonomous operations and AI assisted development, highlighted by Bits AI and a roadmap for AI driven detection, investigation and remediation, can increase reliance on Datadog telemetry and analytics and support premium pricing, revenue growth and potentially higher operating margins.

See why 179 investors see Datadog as 40% undervalued.

Result: Fair Value of $292 (UNDERVALUED)

Still, a single nine figure customer already trimming usage, along with ongoing insider selling around US$320m in stock, could quickly challenge the optimistic Datadog narrative.

Another way to look at Datadog’s valuation

The fairness check using P/S paints a very different picture for Datadog. The stock trades at about 14.7x sales, while the US Software group sits nearer 3.5x and close peers average 7.8x. The fair ratio is 13.3x. That gap points to richer expectations and raises the question: How much execution miss would it take for the multiple to drift toward that fair ratio level?
