Integral Ad Science (IAS): Revisiting Valuation After a 17.9% 90-Day Share Price Rebound

Integral Ad Science Holding (IAS) has been quietly grinding higher this past quarter, and that steady climb is catching more investor attention. With solid double digit revenue and earnings growth, the stock’s recent move invites a fresh look.

See our latest analysis for Integral Ad Science Holding.

Over the past year, Integral Ad Science Holding’s share price has been choppy, but a 17.9% 90 day share price return from a recent low suggests momentum is rebuilding as investors warm to its growth profile and improving profitability.

If this kind of steady re rating interests you, it is worth scanning fast growing stocks with high insider ownership to spot other fast moving companies where insiders have real skin in the game.

With shares still trading below some valuation estimates but not dramatically under Wall Street targets, the key question now is simple: is Integral Ad Science Holding genuinely undervalued, or is future growth already priced in?

Most Popular Narrative: 2.9% Undervalued

With Integral Ad Science Holding last closing at $10.28 against a narrative fair value near $10.59, the story leans modestly in favor of upside, setting the stage for one core growth driver.

The continued shift of ad budgets from traditional to digital channels, along with growing complexity in digital ad environments such as Connected TV (CTV), social media, and mobile apps, is driving sustained demand for IAS's cross platform verification and optimization solutions supporting long term revenue and customer base growth.

Want to see what this demand story looks like in numbers? Behind this fair value sits a powerful mix of rising margins, accelerating earnings, and a future profit multiple that assumes IAS keeps earning premium status in the ad tech stack.

Result: Fair Value of $10.59 (UNDERVALUED)

However, this upside view could unravel if key platform partners internalize verification tools, or if tighter privacy rules blunt IAS’s measurement and targeting advantages.

Another View on Value

On earnings, IAS looks far less forgiving. The stock trades on a 36.9x price to earnings ratio, well above both the US Media industry at 15.4x and a 20.5x fair ratio, implying investors already pay up for growth. If the deal falters, does that premium still hold?
