The call in brief
Read the Q3 2025 earnings summary ↗Akamai delivered a strong Q3 2025 with revenue of $1.055 billion, up 5% as reported (4% cc) and above guidance, non-GAAP operating margin improving to 31%, and non-GAAP EPS of $1.86, up 17% and $0.20 above the high end of guidance. Growth was led by Cloud Infrastructure Services, which reached $81 million and accelerated to 39% year-over-year (from ~30% in Q2), with all three top U.S. cloud providers now on CIS. Security revenue rose 10% to $568 million, and high-growth API Security plus Zero Trust hit $77 million, up 35%, with API Security more than doubling post-NoName and set to exit 2025 near a $100 million run rate. Total compute grew 8% to $180 million, held back roughly 5 points by a $7 million one-time deferred-revenue benefit in Q3 2024. Delivery declined 4% to $306 million but beat expectations, continuing its stabilization. The centerpiece was the launch of Akamai Inference Cloud with NVIDIA Blackwell 6000 across 17 locations, positioning Akamai for distributed, low-latency AI inference at the edge, a shift validated by a new IDC report. For Q4, management guided revenue of $1.065B-$1.085B and EPS of $1.65-$1.85, with full-year EPS of $6.93-$7.13; compute will land a touch under 15% on later contract ramps, and no shares were repurchased in Q3 despite a record $800 million YTD.
- Total revenue grew to $1.055 billion, up 5% year-over-year as reported and 4% in constant currency, coming in above the high end of guidance.
- Non-GAAP EPS reached $1.86, up 17% year-over-year both as reported and in constant currency, landing $0.20 above the high end of the guidance range.
- Cloud Infrastructure Services (CIS) revenue was $81 million, accelerating to 39% year-over-year growth from roughly 30% in the prior quarter, and all three of the top U.S. cloud providers are now using Akamai CIS.
- Security revenue was $568 million, up 10% year-over-year (9% in constant currency), with high-growth products API Security and Zero Trust Enterprise Security at $77 million, up 35% (34% cc).
- Non-GAAP operating margin improved to 31%, and the company generated non-GAAP net income of $269 million.
- Delivery revenue of $306 million (down 4%) came in slightly better than expected, marking another quarter of stabilization and improved trends in the delivery business.
- Akamai launched Akamai Inference Cloud with NVIDIA at GTC, live in 17 locations on NVIDIA Blackwell 6000 infrastructure, with strong early customer interest (Monks, Harmonic) for edge AI inference.
- Signed sizable cross-portfolio deals, including a $37 million two-year renewal with a Japanese gaming company, a $31 million multi-year security-and-compute commitment with a major European bank ($7M of it API Security), and a $20 million expansion with one of the world's largest airlines.
- Delivery revenue declined 4% year-over-year to $306 million, remaining a drag on total growth despite stabilization.
- Compute revenue growth of 8% as reported was held back by a tough compare: a $7 million one-time deferred-revenue benefit recorded in Q3 2024 that added about 5 percentage points to the prior-year compute growth rate.
- Full-year compute growth is now expected to be a touch under 15%, below prior expectations, because some larger CIS contracts ramped later in the year than anticipated.
- The Other Cloud Applications (OCA) portion of compute (~$100M) was roughly flat quarter-over-quarter, weighed down by storage and video-optimization workflow headwinds being transitioned to a partner.
- The company did not repurchase any shares in Q3, its first quarter without a buyback since around 2009.
- Q4 non-GAAP operating margin guidance of approximately 28%-30% implies sequential margin pressure, partly from a seasonal jump in sales commissions and early inefficiency from AI inference buildout.

As a reminder, we'll be referring to certain non-GAAP financial metrics during today's call. A detailed reconciliation of GAAP to non-GAAP metrics can be found under the financial portion of the investor relations section of akamai.com. With that, I'll now hand the call off to our CEO, Dr. Tom Leighton.
Thanks, Mark. I'm pleased to report that Akamai had a strong third quarter with results coming in above expectations for revenue, margin, and earnings per share. Revenue grew to $1.055 billion, up 5% year-over-year as reported, and up 4% in constant currency. Non-GAAP operating margins improved to 31%, and non-GAAP earnings per share was $1.86, up 17% year-over-year as reported and in constant currency. Our business performed well across the spectrum of our portfolio, with accelerating momentum for our cloud infrastructure services, or CIS, continued strong demand for our high-growth security products, and continued stabilization of our delivery revenue. We're especially pleased with the greater recognition of the strength of our distributed platform and differentiated strategy among customers and industry analysts.
For investors who may be less familiar with how we have transformed Akamai's business model from the CDN pioneer to a leader in cloud security and distributed cloud computing, I encourage you to read the new report on Akamai from IDC titled, "Akamai: Navigating the Cloud Frontier, A Transformation from CDN to Distributed Cloud Provider." It offers an objective third-party perspective of how Akamai has evolved, our strategy, and our key differentiators in security and distributed cloud computing for AI inferencing at the edge. You can find the report on our website. As a great proof point for the advantages offered by Akamai's uniquely distributed compute capabilities, the top three cloud providers in the U.S. are all now using Akamai Cloud Infrastructure Services. In Q3, one of them signed an expanded multi-year renewal that solidifies Akamai's position to be their premier distributed cloud computing provider.
This customer has a dominant position at the core of the internet and uses our widely distributed Managed Container Service to get their business logic closer to end users for superior performance. Our revenue for Cloud Infrastructure Services in Q3 was $81 million, up 39% year-over-year as reported and in constant currency. That is an acceleration from the 30% growth rate we had in Q2. We signed many new and expanded contracts for our Cloud Infrastructure Services in Q3, including with a major global appliance and consumer electronics manufacturer in South Korea, a multinational financial services company in Singapore, a leading U.S. developer of analytic software, a U.S.-based supply chain planning software vendor, a European cybersecurity provider, a major U.S. airline, a leading American video game company, a leading media and entertainment company in India, and one of the largest media companies in the world.
Also, a multinational gaming company in Japan contracted for our Cloud Infrastructure Services as part of a larger $37 million two-year renewal for an array of Akamai products and services. Last week, I was with our team at the AI Industry Conference in VidyaGTC, where Akamai took a major step toward the future with the launch of Akamai Inference Cloud, our platform to support the growing demand to scale AI inference on the internet. With the rise of AI, the internet is undergoing a fundamental shift in architecture. The internet we're building today is driven by AI, where human intelligence is supported and augmented by intelligence systems powered by AI inference. Akamai is positioned to power inference the way we power the web, by bringing inference physically close to users. This will enable faster performance and global scale to support intelligent applications worldwide.
When the web was first taking hold, the need for performance and scale is what catalyzed Akamai's founding. Akamai helped to end what was known as the worldwide wait, enabling the internet to scale to provide real-time services to billions of people around the world. Subsequently, we introduced web security as a cloud service, enabling the web to be used safely for myriad critical applications such as banking and commerce. We see the same need for performance, scale, and security playing out again with AI inference today. By combining highly scaled GPU and compute capacity with Akamai's unparalleled global reach and security at the edge, Akamai Inference Cloud enables intelligence to run instantly, securely, and exactly where it's needed, right next to the user, agent, or device.
This is how Akamai can power the new generation of AI applications: conversational, personalized, and agentic, all designed to scale in real time to meet unprecedented demand. As we look at AI investment cycles, we see the market at a transition point. Until now, the AI story has largely focused on training, the initial creation of AI models from massive amounts of underlying data. To train foundation models, AI pioneers have relied on hyperscale clouds and their centralized data centers with their enormous concentrations of compute, power, and capital. We believe that AI inference, or the execution of queries against a trained model, is the new frontier, one that requires purpose-built infrastructure to enable distributed, low-latency, globally scalable inference at the edge, with response times measured in a few tens of milliseconds.
As AI systems are adopted at scale, we expect the growth of inference will drive enormous demand to this new intelligent layer of the internet. We are not the only ones who see it coming. Fortune Business Insights noted in a report on the rising global AI inference market that due to rising demand for real-time low-latency AI processing near data sources, edge inference leads the market and is projected to grow at the highest CAGR of all AI inference models.
As NVIDIA's founder and CEO, Jensen Huang, said when we launched Akamai Inference Cloud at GTC, quote, "Inference has become the most compute-intensive phase of AI, demanding real-time reasoning at planetary scale." Together, NVIDIA and Akamai are moving inference closer to users everywhere, delivering faster, more scalable generative AI and unlocking the next generation of intelligent applications." Akamai Inference Cloud brings together Akamai's globally distributed architecture and expertise with NVIDIA's Blackwell AI infrastructure to provide the computing needed to unlock AI's true potential. The service is available today with 17 locations around the world, and we're building out more points of presence as customer demand grows. One of our initial customers, Monks, the European digital-first marketing technology services and consulting company, said, quote.
With Akamai Inference Cloud, we will accelerate the delivery of key capabilities, including identifying players and plays, and delivering tactical insights to coaches while the game is still happening. That is only possible by distributing advanced GPUs to the edge, and we believe it will transform how we approach sports broadcasting and immersive fan experiences." Another customer, Harmonic, whose technology helps to distribute video content for television and the internet, said, quote, "Akamai Inference Cloud will allow us to run larger parameter, more capable models locally, expanding the number of functions we can deliver cost-effectively within the same compute instance to deliver fast response times, sophisticated personalization, and more enriching video content." At Akamai, we believe the technology ecosystem that enables the AI revolution will require multiple providers of AI infrastructure: the hyperscalers, NVIDIA, and also Akamai with our unique distributed capabilities and our unparalleled expertise at the edge.
We are very excited about what lies ahead. The edge, of course, is also where Akamai deploys our security solutions. As customers speak with us about their plans for AI inferencing, they tell us they see valuable synergy between Akamai's security and delivery product lines and our cloud computing capabilities, and how they trust Akamai to help make the internet faster, more reliable, and secure for their businesses. Akamai's security growth in Q3 continued to be driven by strong demand for our market-leading segmentation solution and by rapidly growing customer adoption of our API Security solution. Combined, these high-growth security products grew revenue 35% year-over-year as reported and 34% in constant currency.
Our segmentation wins in Q3 included a $3 million expansion contract to give one of North America's largest healthcare technology companies the visibility and control they didn't have before, a $1 million contract with a European insurance group that is also a net new Akamai customer, a multi-year contract with a large insurance company in Korea, and an expansion contract with a large bank in Mexico to extend their initial deployment across their operations in Latin America.
In Q3, we also continue to see growing interest in our market-leading API security solution as organizations shift towards an API-first strategy and expand their use of AI applications that rely on APIs in a fundamental way, adopt tools that enable them to discover and monitor deployed APIs and to manage risk, comply with stricter data protection regulations, especially in Europe, and respond to public reports of API-related breaches that have raised awareness and increased the stakes for financial and reputational loss. Akamai API security wins in Q3 included a $7 million contract for API security with one of Europe's most important banks as part of a $31 million multi-year commitment for security and compute. Adoption of API security as part of a $20 million expansion contract with one of the world's largest airlines.
Thank you, Tom. I'm pleased to report that we delivered strong third-quarter results with total revenue of $1.055 billion, up 5% year over year as reported and 4% in constant currency. We also had another quarter of very strong bottom-line performance with non-GAAP EPS of $1.86 per share, up 17% year-over-year as reported and in constant currency. Our strong EPS results were driven by higher-than-expected revenue and strong execution across the board. Moving now to revenue. Compute revenue, which is comprised of the fast-growing cloud infrastructure service or CIS solutions that Tom mentioned earlier, and our other cloud applications or OCA, was $180 million, up 8% year-over-year as reported, and up 7% in constant currency.
As a reminder, in Q3 2024, we recorded a $7 million one-time benefit related to the release of some deferred revenue in conjunction with the expiration of a long-term legacy compute contract. This revenue was part of our other cloud application products, and it had a 5 percentage point impact on the year-over-year total compute revenue growth rate. Total compute revenue was driven by continued strength in CIS. For Q3 2025, CIS revenue was $81 million, accelerating to 39% growth year over year as reported and in constant currency, a nice step up from approximately 30% growth last quarter. As a result, we continue to expect CIS ARR year-over-year growth in the range of 40%-45% in constant currency at year-end. Security revenue was $568 million, up 10% year-over-year as reported and 9% in constant currency.
Revenue from our high-growth security products, by that I mean API Security and Zero Trust Enterprise Security, was $77 million, an increase of 35% year over year and 34% in constant currency. Given the continued strength in our API Security business, we now expect to exit 2025 with a run rate of approximately $100 million for that product line on both an as-reported and constant-currency basis. Finally, we continue to expect the combined ARR for our high-growth security solutions to increase by 30%-35% year-over-year in constant currency for 2025. Moving to delivery, revenue was $306 million, down 4% year-over-year as reported and in constant currency. This result was slightly better than expected, marking another quarter of improved trends in our delivery business. International revenue was $525 million, up 9% year-over-year, or up 8% in constant currency, representing 50% of our total revenue in Q3.
Foreign exchange fluctuations had a positive impact on revenue of $4 million on a sequential basis and positive $8 million on a year-over-year basis. Moving to profitability. In Q3, we generated non-GAAP net income of $269 million, or $1.86 of earnings per diluted share, up an impressive 17% year-over-year as reported and in constant currency, and $0.20 above the high end of our guidance range. Finally, our Q3 CapEx was $224 million, or 21% of revenue, as we continue to invest in our fast-growing CIS business. Moving to cash in our capital allocation strategy. As of September 30, our cash and cash equivalents and marketable securities totaled approximately $1.8 billion. During the third quarter, we did not repurchase any shares. As a reminder, year to date, we spent $800 million to buy back approximately 10 million shares, marking the largest annual buyback in our history.
As it relates to our use of capital, our intentions remain the same: to continue buying back shares over time to offset dilution from employee equity programs and to be opportunistic in both M&A and share repurchases when market and business conditions warrant. Before I provide our Q4 and full-year 2025 guidance, I want to touch on some housekeeping items. First, as in prior years, seasonality plays a significant role in determining our financial performance for the fourth quarter. Typically, we see higher-than-normal traffic from our large media customers and a pickup in seasonal online retail activity from our e-commerce customers. However, both are difficult to predict. Second, regarding Q4 operating expenses, as is typical for our business, we expect them to be higher than in Q3. The main driver is the seasonal jump in sales commissions as our most successful reps achieve their annual quota accelerators.
Finally, on July 4th, 2025, the One Big Beautiful Bill Act was signed into law, introducing significant provisions such as the permanent extension of certain expiring tax cuts and Jobs Act provisions, international tax framework modifications, and it restored some business tax benefits. This new legislation, however, has not had a material impact on our tax rate in 2025. With those factors in mind, I'll move to our Q4 guidance. For Q4, we are projecting revenue in the range of $1.065 billion-$1.085 billion, up 4%-6% as reported, and up 3%-5% in constant currency over Q4 2024. At current spot rates, foreign exchange fluctuations are expected to have a negative $5 million impact on Q4 compared to Q3 levels and a positive $11 million impact year-over-year.
For the full year, at current spot rates, our guidance assumes foreign exchange will have a positive $13 million impact on revenue in 2025 on a year-over-year basis. At these revenue levels, we expect cash gross margins of approximately 72%-73%. Q4 non-GAAP operating expenses are projected to be $322 million-$331 million. We expect Q4 EBITDA margin to be approximately 42%-43%. We expect non-GAAP depreciation expense to be between $143 million-$145 million, and we expect non-GAAP operating margin of approximately 28%-30% for Q4. Moving on to CapEx, we expect to spend approximately $171 million-$181 million. This represents approximately 16% of our total projected revenue. Based on our expectations for revenue and cost, we expect Q4 non-GAAP EPS in the range of $1.65-$1.85.
This non-GAAP guidance assumes taxes of $57 million-$60 million based on an estimated quarterly non-GAAP tax rate of approximately 18%-19%. It also reflects a fully diluted share count of approximately 147 million shares. Our complete guidance for full year 2025 is available in today's press release, but let me walk you through the highlights for now. For the full year, we expect total revenue to grow 4%-5% in constant currency, non-GAAP operating margin of approximately 29%-30%, and EPS in the range of $6.93-$7.13. In closing, we continue to be very pleased with the performance of our cloud infrastructure service and high-growth security solutions. We were very excited about the potential of the Akamai Inference Cloud as we extend AI to the edge. With that, I'll wrap things up, and Tom and I are happy to take your questions. Operator?
