Cloudflare, the web infrastructure and security company, just delivered its fastest quarterly revenue growth in nearly four years, and analysts at Truist say the results point to something bigger: the company is becoming essential plumbing for the "agentic internet."
For the September quarter, Cloudflare reported revenue of $782.5 million, up 39% from a year earlier and ahead of the $737.2 million that Wall Street had expected. The company also guided to $845–$846 million for the current quarter, above the $828.5 million consensus. That combination of a beat and a raise is what caught investors' attention.
What's driving the acceleration?
Truist, a U.S. bank, argues that the rebound is not a one-off product win. Instead, the strength looks broad-based. The bank points to stronger customer spending, more additions of large customers, and improving operating margins as evidence that Cloudflare's growth is sustainable.
That matters because Cloudflare operates in a competitive space, going up against larger, more established players like Akamai. While Akamai has been growing more slowly, Cloudflare's mix of faster growth and improving profitability stands out. Investors will be watching to see if similar trends show up when Palo Alto Networks and Zscaler report earnings soon.
The "agentic internet" is a term for a future where AI agents—software that can perform tasks autonomously—interact with websites, APIs, and other digital services. For that to work, there needs to be fast, secure, and reliable infrastructure underneath. Cloudflare's network, which sits between users and websites, is well-positioned to be that layer.
The catch: rising memory costs
But there's a wrinkle on the cost side. Truist flagged that higher memory prices are starting to lift Cloudflare's cost of revenue—essentially what it spends to run its network. Memory chips are a key input for Cloudflare's servers, and when prices rise, they can squeeze gross margin if the company can't pass those costs on to customers.
Cloudflare's management says the pressure is manageable. They point to earlier memory procurement—buying components ahead of price increases—plus productivity gains and the benefits of scale. In other words, they believe they can offset higher input costs without sacrificing growth.
That's a crucial claim. Markets like high growth, but they reward it most when each new dollar of revenue brings in more profit. If Cloudflare can maintain its growth while protecting margins, its improving operating leverage becomes a clearer differentiator versus slower-growing rivals.
What it means for investors
For everyday investors, the key question is whether Cloudflare's re-acceleration is as profitable as it is fast. The company's guidance for the current quarter suggests revenue will keep climbing, but the real test will be in the margin numbers.
If Cloudflare can deliver on its margin promises, it could set a positive tone for the entire cloud security group. As Palo Alto Networks and Zscaler report, investors will be listening for similar signals about demand and pricing power. A strong showing from Cloudflare could also boost sentiment for other companies that rely on AI-driven infrastructure spending.
On the other hand, if memory costs prove harder to offset than expected, Cloudflare's growth story could lose some of its shine. That's why the company's procurement strategy and productivity efforts are worth watching.
For now, Cloudflare's numbers are turning heads. The company is growing faster than it has in years, and analysts see that as evidence of a structural shift toward AI-ready infrastructure. But the margin story is still unfolding, and that's where the next few quarters will matter most.
