Assessing SentinelOne (S) Valuation as Purple AI Momentum and $1B ARR Shift Focus Beyond Endpoint Security

Simply Wall St

SentinelOne (S) has landed squarely in the spotlight after crossing $1 billion in annual recurring revenue and showcasing its Purple AI driven platform in high profile breach investigations, giving investors fresh reasons to revisit the stock.

See our latest analysis for SentinelOne.

Despite the excitement around its AI platform and high profile breach work, SentinelOne’s 1 year total shareholder return of around negative 37% and year to date share price return of roughly negative 33% show sentiment has cooled, even as its 3 year total shareholder return stays modestly positive.

If you like SentinelOne’s AI driven angle but want to see what else is out there, this is a good moment to explore high growth tech and AI stocks for fresh ideas.

With shares trading at a discount to both analyst targets and high growth peers, yet still loss making as it pivots into a broader AI platform, is SentinelOne quietly undervalued, or is the market already discounting all that future growth?

Most Popular Narrative Narrative: 30.0% Undervalued

With the most followed narrative pointing to a fair value near 21.55 dollars against a 15.08 dollar last close, the valuation hinges on aggressive improvement in growth and margins over the next few years.

The new SentinelOne Flex licensing model is accelerating multi product adoption, leading to larger deal sizes, increased platform retention, and rising recurring revenue, all of which support both near term and long term net margin expansion through reduced sales friction and deeper customer integration.

However, execution risks around international expansion, combined with heavy reliance on hyperscaler partnerships, could pressure margins and growth if regulatory or competitive dynamics turn less favorable.

Another Angle on Valuation

On sales based metrics, SentinelOne looks far less cheap. Its price to sales ratio of 5.4 times tops the US Software industry at 4.9 times, even though our fair ratio suggests the market could justify 6 times. Is this a margin of safety, or a value trap in disguise?
