Akamai grew revenue 5% to $1.10 billion as security and cloud infrastructure offset a shrinking CDN business, but GAAP operating income fell 47% on a stock-compensation timing change and network build-out costs, and the company suspended buybacks to fund a $3.5 billion cloud capacity expansion.
Overview
Akamai grew revenue 5% in the June 2026 quarter and lost nearly half its reported operating profit doing it. Revenue was $1,099.7 million against $1,043.5 million a year earlier, but GAAP income from operations fell 47% to $80.3 million, and the GAAP operating margin — the share of revenue left after paying all the costs of running the business, before interest and tax — dropped from 14.5% to 7.3%.
That gap is the whole story of the quarter. Akamai is spending to convert itself from a content delivery network (a CDN — the global server footprint that caches websites and video close to end users) into a security and cloud-infrastructure vendor, and in Q2 2026 the spending arrived well ahead of the revenue.

Starting in Q1 2026, Akamai split its reporting into three revenue lines instead of two, carving cloud infrastructure services (compute and storage, the EdgeWorkers product, and third-party compute partners running on Akamai's platform) out as its own category. Prior-year figures were restated on the same basis, so the comparisons above are like-for-like.
Security ($604.4M, +9.5%) is now 55% of the company. The 10-Q attributes the growth to "key products in our security solutions portfolio, including our API security, web application and Guardicore segmentation solutions" — API security protects the machine-to-machine interfaces apps use to talk to each other, and Guardicore segmentation walls off parts of a corporate network so an intruder who gets into one part can't move freely through the rest.
Cloud infrastructure services ($99.3M, +39.0%) is the fastest-growing line and the smallest, at 9% of revenue. Growth came from "new and existing customers of our compute solutions, as well as the compute partner solutions running on our platform."
Delivery and other cloud applications ($395.9M, −5.8%) is the legacy CDN business, and it is shrinking for two distinct reasons that management separates: "downward pricing of contract renewals," plus a belief that "macroeconomic headwinds are causing some delivery and other cloud applications customers to increase their focus on cost optimization, which negatively impacted traffic on our network." The first is price; the second is volume. Both are pointed the same way.
Net of all three, total growth was 5.4% — and currency did essentially nothing to it this quarter. Exchange-rate moves cut revenue by $1.1 million in Q2, so the reported 5% and the constant-currency 5% are the same number. The six-month picture is different: a $17.5 million currency tailwind is the reason first-half revenue grew 6% as reported but 5% adjusted for exchange rates. Anyone reading the half-year figures should discount roughly a point of that growth as FX.
Why profit fell three times faster than revenue rose
Cost of revenue rose 13.9% to $485.9 million, taking 44% of revenue versus 41% a year ago. The 10-Q's own line-item detail shows where:

Network build-out grew fastest "particularly due to partner costs as we expand our compute partner program" — Akamai is paying partners to run compute capacity on its platform, which grows revenue and cost of revenue together and structurally caps how profitable that revenue can be. Co-location (renting space and power in third-party data centers), bandwidth, and equipment depreciation all rose from "investment in our network, particularly as we build out our platform, including to support cloud infrastructure services and AI applications."
Below the gross-margin line, every operating expense category grew double-digits: R&D +18.3% to $148.8 million, sales and marketing +16.3% to $170.0 million (driven by headcount from "our reinvestment in our go-to-market strategy"), and G&A +15.4% to $187.7 million.
A large slice of that expense growth is an accounting change in disguise, not a cash cost. Total stock-based compensation was $146.3 million, up $33.5 million, and the 10-Q repeats the same explanation in all four expense sections: "a new benefit that reduced the service period for retirement eligible employees effective in 2026." Shortening the vesting period pulls expense that would have landed in later years into 2026, so the recognized cost jumps without the underlying awards changing. Add the $3.1 million increase in amortization of previously capitalized stock compensation, and stock-related expense accounts for roughly $36.6 million of the $71.2 million operating-income decline — a bit over half of it. Management says explicitly to expect this pressure for the rest of the year.
Strip out stock compensation, acquisition intangible amortization and restructuring, and non-GAAP operating income fell 12.3% to $270.7 million, with margin down five points to 24.6%. That smaller decline is the cleaner read on the underlying business: real, but a fraction of the 47% GAAP drop.
Two items below the operating line cushioned net income, which fell 23.4% — only half the rate of operating income. Interest and marketable-securities income more than doubled to $31.7 million, "primarily due to interest earned from marketable securities purchased during the three months ended June 30, 2026 using proceeds from our convertible senior notes." And the effective tax rate fell to 20.6% from 31.8%. Neither has anything to do with operations.
GAAP EPS fell harder still, 26.8% to $0.52, because diluted share count rose to 153.7 million from 145.2 million — despite Akamai retiring 5.0 million shares in the first half. New convertible notes pull potential shares into the GAAP diluted count, and GAAP does not let the company offset them with the hedges it bought for exactly that purpose. Akamai's non-GAAP share count subtracts 5.4 million shares for that hedge benefit, which alone accounts for $0.06 of the $1.07 gap between GAAP and non-GAAP EPS.
The $3.5 billion financing, and the buyback that stopped
In May 2026 Akamai issued $1.75 billion of convertible notes due 2030 and $1.75 billion due 2032, both at zero coupon interest, "to fund the accelerated capital expenditure requirements in support of our cloud infrastructure services, prioritizing the rapid build-out of our global footprint." Total convertible debt outstanding is now $7.64 billion, and total liabilities climbed to $10.32 billion from $6.50 billion at year-end 2025.
Three things in that disclosure matter more than the headline:
The capex surge has not started yet. First-half purchases of property, equipment and capitalized software were $417.6 million, essentially flat against $419.8 million a year earlier. The $3.5 billion raised went into marketable securities ($2.27 billion of purchases in the half), not the ground. So the depreciation drag from this build is still almost entirely ahead of Akamai, not in the current margin. Two leading indicators say it is close: accrued-but-unpaid capex in payables tripled to $191.2 million from $75.6 million, and new operating lease commitments taken on in the half more than doubled to $399.6 million from $182.7 million — data-center space signed but not yet drawing depreciation.
Share repurchases are over for the year. Akamai bought back $410 million of stock in Q2 at an average $134.54, and $615.7 million across the half at $123.19. But the 10-Q states flatly: "We do not expect any share repurchases for the remainder of 2026 as we continue to invest in our platform to support cloud infrastructure services." That leaves $564.8 million of the May 2024 authorization unused. A company that has historically bought back stock to offset employee equity dilution is now suspending that while stock compensation is rising 30% — dilution should be expected to continue building.
One tranche is now convertible on demand. The 2033 notes were moved into current liabilities because the share-price trigger was met at June 30, making them convertible at holders' option during Q3. No holder has converted yet, per the filing. It is a reporting consequence of a higher share price rather than a liquidity problem — Akamai holds $4.616 billion of cash and marketable securities — but it is real optionality sitting with noteholders.
Operating cash flow was $326 million in the quarter, 30% of revenue; the half-year figure fell to $638.8 million from $710.3 million on "timing of customer collections, higher payroll and related costs due to increased headcount and higher lease payments for co-location facilities."
The demand case
The strongest evidence for the strategy is contractual rather than in the income statement. Management disclosed more than $2.8 billion of multi-year cloud-infrastructure contracts signed year-to-date, including one new US technology customer committing more than $600 million over four years to power robotics development. Company-wide remaining performance obligations — revenue under signed, non-cancellable contracts not yet delivered — stood at $7.6 billion at quarter-end, with roughly 40% expected to convert to revenue in the next twelve months and another 40% over two to three years.
Against $99.3 million of quarterly cloud-infrastructure revenue, a $2.8 billion signed backlog implies a step-change in that line. It also explains the debt: serving those commitments requires the footprint before the revenue arrives, and the filing names the execution risk directly, including "our ability to deploy the infrastructure necessary to service such commitments on anticipated timelines and our ability to procure sufficient hardware and memory at anticipated costs."
Takeaway: Akamai has pre-sold $2.8 billion of cloud-infrastructure capacity it has not yet built, funded with $3.5 billion of zero-coupon converts that are still sitting in marketable securities. The 47% GAAP operating-income drop this quarter is mostly a stock-compensation timing change plus co-location and partner costs — the depreciation from the actual build has barely begun, and management has cut off buybacks to pay for it. The transition is now financed and contracted; what remains unproven is the margin it earns once the capacity is live.

The Q3 revenue midpoint of $1,117.5 million is only 1.6% above Q2, and the full-year midpoint of $4,487.5 million implies second-half revenue of about $2,314 million, roughly 6.5% above the first half's $2,173 million. That is a modest acceleration, consistent with cloud infrastructure compounding off a small base while delivery keeps eroding. Non-GAAP margin guidance of 25–26% for the year effectively says Q2's 24.6% is the floor and management does not expect further compression — a claim to test against its own warnings in the same filing about rising co-location, server and memory prices "due to market dynamics driven by hyperscalers."
Our read: the revenue path is the more credible half of this guidance, because the security line is growing near 10% off a $2.4 billion annualized base and the cloud backlog is contracted rather than forecast. The margin path is the harder half. Three costs management has already told investors will rise through the rest of 2026 — stock compensation from the retirement-eligibility change, co-location and hardware prices, and partner payments under the compute program — are the same three that produced this quarter's compression, and the depreciation from the $3.5 billion build has not yet entered the P&L at all. Holding 25% non-GAAP margin against that requires the newly signed cloud revenue to land on schedule and at better unit economics than the current mix. Watch two things in the Q3 filing: whether cash capex finally inflects from its flat ~$210 million-per-quarter run rate, and whether cloud infrastructure revenue growth holds near 39% as the comparison base rises.
