Fortinet Just Posted Record Margins. So Why Is Everyone Selling?

Fortinet reported Q3 2025 earnings on November 5th. 

The numbers looked solid on paper. But $FTNT ( ▲ 0.19% ) is still down 12.88% this year.

Here's what's really going on.

YTD Return: -12.88%
Market Cap: $60.26B
P/E Ratio: 33.89

Revenue came in at $1.72 billion. That's up 14% from last year. Billings hit $1.81 billion, also up 14%.

CEO Ken Xie highlighted two bright spots: Unified SASE grew 19% and SecOps jumped 33%. 

Those are the high-margin subscription businesses Wall Street loves.

Operating margin hit a record 36.9%. 

Free cash flow reached $600M+ with a 37% margin. These aren't the numbers of a struggling company.

So why is $FTNT underperforming?

Here's where it gets tricky. 

Management guided Q4 billings growth to ~11.5%. That's down from the 14% they just delivered in Q3.

Wall Street hates deceleration.

Even if you're growing at a healthy clip, slowing momentum kills sentiment. And that's exactly what's happening here.

Fortinet isn't failing. It's transitioning.

Product revenue grew 18% in Q3. That's actually strong. But service revenue only grew 13%. For a company trying to sell more subscriptions, that's not the mix investors want to see.

Look deeper and you see FortiSASE billings exploded 68% YoY. 

Unified SASE now represents 26% of total billings, up from 25% last quarter. 

SecOps is 11% of billings, up from 9%.

These are the high-value, recurring revenue streams that should command a premium valuation. 

Multiple law firms are still investigating whether Fortinet misled investors. These cases haven't been resolved. They probably won't be for months.

Lawsuits create uncertainty. And markets price in uncertainty with a discount. 

That's part of why you're seeing $FTNT trade at 33.88x earnings instead of the 40x+ multiples some cybersecurity peers command.

Is $FTNT cheap or expensive compared to competitors?

Zacks maintains their #2 ‘Buy’ rank. They point to Fortinet's position across networking and security as a competitive advantage.

One analyst noted: "Fortinet remains well-positioned in the cybersecurity space despite near-term headwinds."

But others downgraded price targets after Q4 guidance came into light. 

The concern isn't about today's business. It's about whether growth can reaccelerate in 2026.

Full year 2025 guidance calls for $7.37-7.47 billion in billings. That's 13.6% growth at the midpoint.

Management expects to hit their "Rule of 45" target. That means revenue growth plus operating margin adds up to at least 45%. They've beaten it five years running.

The question is 2026. 

Can FortiSASE and SecOps growth accelerate enough to offset any firewall headwinds? Can they land more of those $1M+ deals, which grew 32% in Q3?

CEO Xie keeps talking about "vendor consolidation" as the key driver. Companies want one platform for networking and security instead of buying from multiple vendors. 

Fortinet owns that integrated story better than anyone.

But Palo Alto $PANW ( ▲ 0.83% ) and CrowdStrike $CRWD ( ▲ 3.46% ) aren't standing still. They're pushing hard into the same accounts.

Should you buy this dip? That depends on what you believe.

If you think Fortinet's SASE and SecOps businesses will keep growing 20-30%+ and eventually dominate the revenue mix, this could be your entry point. 

The company is profitable, generates cash, and trades cheaper than it did a year ago.

The lawsuits are noise. They'll get resolved. 

The real question is whether Fortinet can prove it's still a growth story in 2026.
