All balance sheet, income statement and cash flow figures below are from Datadog's Form 10-Q for the quarterly period ended June 30, 2026, as filed with the SEC. Customer counts, ARR percentages, non-GAAP measures and guidance are from the company's Q2 2026 earnings release and call. Growth rates for periods before 2025 are from prior filings, not this one.
Datadog is growing faster at a $4.5 billion run-rate than it was two years ago at a materially smaller scale — revenue rose 35.6% to $1.12 billion, against 32.2% in Q1 2026. But the return to GAAP profitability is thinner than the net income line implies: operating income was $5.5 million, a 0.49% margin, and $46.3 million of the $51.7 million in pre-tax income was net other income — chiefly $50.6 million of interest earned on the company's $4.55 billion marketable securities portfolio ($4.99 billion including cash), net of $3.3 million of interest expense and a $1.0 million other loss. Nearly 90% of Datadog's pre-tax income — and more than 100% of its after-tax net income — is a treasury outcome, not an operating one.
And that treasury engine is not growing. Interest income of $50.6 million was slightly below the $50.8 million earned in Q2 2025, and $99.8 million for the half against $101.5 million — a 1.7% decline — even as the portfolio itself grew 11.4% over six months. Datadog is earning less on more money, which means reinvestment yields are falling faster than the balance is rising. The line that currently supplies the entire bottom line is a decaying one.
The gap between GAAP and adjusted framings is wide — the company's reported 23% non-GAAP operating margin against a 0.49% GAAP margin is a distance of roughly 22 percentage points — though it is worth noting that stock compensation as a share of revenue is actually falling, from 21.7% to 19.6%. The gap is wide because the GAAP base is thin, not because the add-backs are growing.
1. Balance Sheet
1-1. Principal Asset Movements
| Item | Dec 31, 2025 ($M) | Jun 30, 2026 ($M) | Change % |
|---|---|---|---|
| Cash and cash equivalents | 401.3 | 435.0 | +8.4 |
| Marketable securities | 4,073.5 | 4,550.5 | +11.7 |
| Accounts receivable, net | 741.3 | 827.3 | +11.6 |
| Property and equipment, net | 338.1 | 409.6 | +21.2 |
| Goodwill | 530.6 | 706.7 | +33.2 |
| Intangible assets, net | 15.0 | 23.2 | +54.7 |
| Total assets | 6,643.8 | 7,547.7 | +13.6 |
The dominant feature is liquidity: cash plus marketable securities reached $4.99 billion, up 11.4%, and now equals 66% of total assets. Receivables grew 11.6% against 34.0% first-half revenue growth — collections are keeping pace with the business, not lagging it.
Goodwill rose $176.2 million — $178.7 million added by three acquisitions, less $2.5 million of foreign currency translation and other adjustments. Total purchase consideration was $191.5 million, of which $178.7 million was allocated to goodwill and only $11.5 million to intangible assets. That allocation ratio — 93% goodwill — signals acqui-hire and early-stage technology deals rather than revenue-generating businesses; management explicitly states the acquisitions were immaterial individually and in aggregate, and no pro forma results were presented.
The consideration mix deserves a caveat the filing itself invites. Datadog states the $191.5 million consisted of $98.5 million of cash (net of cash acquired), $14.3 million of deferred holdback payments, and the issuance of 796,509 restricted Class A shares — but the purchase-price note does not assign a dollar value to those shares. The supplemental cash flow disclosure values restricted shares issued for acquisitions at $75.3 million. Those three disclosed components sum to $188.1 million, roughly $3.4 million short of the stated $191.5 million. That residual is small, but it is a reconciliation gap, and it should not be papered over by back-solving the share value to $78.7 million as though the filing had stated it.
Property and equipment grew 21.2% on cash capital expenditure of just $21.2 million, because capitalized software development costs of $61.5 million — up 61.9% year over year — flow into the same line.
Operating lease assets of $206.0 million sit against total lease liabilities of $292.3 million ($44.2 million current, $248.0 million non-current). The $86 million excess of liability over right-of-use asset is ordinary under ASC 842 and does not indicate a hidden obligation. What is mildly informative is the direction: non-current lease liabilities fell from $256.2 million, meaning Datadog signed no material net new long-duration real estate in the half — a company scaling headcount through compute rather than floor space.
1-2. Debt Structure
Financial debt consists of a single instrument: $1.0 billion of 0.00% Convertible Senior Notes due December 2029, carried at $985.5 million. The coupon is genuinely zero — contractual interest expense on the notes was nil in Q2. Of the $3.3 million of total interest expense reported, only $1.05 million relates to the notes, and all of it is issuance-cost amortization (Note 8); the remaining $2.2 million arises outside the convertible. Against $49.5 million of quarterly interest and other income, net — that is, the $50.6 million of interest income less the $1.0 million other loss — the notes' issuance-cost amortization is covered more than 47 times over. The conditional conversion features were not triggered during Q2 2026, leaving the notes classified as non-current; the initial conversion price is approximately $217.60 per Class A share. With no maturities before 2029 and $4.99 billion of liquid assets against $1.0 billion of principal, refinancing risk is negligible.
Operating liabilities tell a more interesting story. Accounts payable more than doubled, from $148.8 million to $313.5 million, driven in part by cloud hosting and infrastructure payables of $191.5 million versus $122.7 million at year-end — a 56% increase that reflects rising compute intensity. The accounts payable movement flattered first-half operating cash flow by $155.1 million per the cash flow statement. That is a timing benefit, not earnings: it will not repeat at this magnitude unless payables keep expanding at the same rate. Deferred revenue, the contractual claim on future service, grew only 6.0% to $1.34 billion.
1-3. Capital Structure
Additional paid-in capital rose $560.0 million in six months to $4.14 billion, against retained earnings of just $234.9 million. The movement reconciles almost entirely to non-cash and employee-related issuance: $433.2 million of total stock compensation (including $16.1 million capitalized into software), $75.3 million of acquisition shares, $39.1 million of ESPP proceeds and $12.5 million of option exercises. Retained earnings increased by $97.1 million — exactly the six-month net income — confirming no dividends or buybacks.
Shares outstanding rose from 352.5 million to 359.0 million, up 1.82% in six months. Datadog operates no repurchase programme, so dilution runs uncorrected. Accumulated other comprehensive income swung from positive $15.4 million to negative $6.8 million, a $22.2 million move driven by $17.1 million of unrealized losses on the securities portfolio.
2. Income Statement
2-1. Quarterly Performance
| Item | Q2 2025 ($M) | Q1 2026 ($M) | Q2 2026 ($M) | YoY % |
|---|---|---|---|---|
| Revenue | 826.8 | 1,006.4 | 1,121.5 | +35.6 |
| Gross profit | 660.8 | 797.2 | 881.3 | +33.4 |
| Gross margin (%) | 79.9 | 79.2 | 78.6 | — |
| Operating income | (35.5) | 7.3 | 5.5 | — |
| Operating margin (%) | (4.29) | 0.73 | 0.49 | — |
| Net income | 2.6 | 52.6 | 44.6 | +1,583 |
| Net margin (%) | 0.32 | 5.22 | 3.97 | — |
Q1 and Q2 2026 both posted positive GAAP operating income, against operating losses in both quarters of the first half of 2025 (this filing covers 2026 and 2025 periods only; the full-year 2025 pattern is in the Annual Report). But the sequential detail undercuts the recovery narrative: revenue grew $115.0 million from Q1 to Q2 while operating income fell $1.9 million. Incremental operating margin on sequential growth was negative.
The cause is gross margin. Cost of revenue grew 44.7% against revenue growth of 35.6%, compressing gross margin 1.34 percentage points year over year and a further 0.62 points sequentially. Datadog is buying more compute per dollar of revenue than it used to — consistent with the $68.8 million increase in cloud hosting payables and with the infrastructure demands of AI-related observability workloads.
2-2. Operating Leverage
Operating expenses grew 25.8%, a full 9.8 points slower than revenue, improving the opex-to-revenue ratio from 84.2% to 78.1%. Research and development, the largest single cost at $478.0 million, fell from 46.9% to 42.6% of revenue; sales and marketing from 28.9% to 27.8%; general and administrative from 8.4% to 7.7%.
The bridge is worth stating plainly: 6.1 points of operating expense leverage, less 1.34 points of gross margin erosion, produced 4.78 points of operating margin improvement. Cost discipline is working — but roughly a fifth of the benefit is being consumed by infrastructure economics before it reaches the operating line.
Stock-based compensation is the item that separates the two views of this company, and it is worth being precise about which adjusted number is whose. Adding back the $220.3 million of Q2 stock compensation to GAAP operating income gives $225.8 million, a 20.1% margin — but that is a stock-compensation-only measure, not Datadog's reported figure. The company's own non-GAAP operating income for Q2 2026 was $257 million, a 23% margin, because it additionally excludes amortization of acquired intangibles, acquisition-related charges and employer payroll taxes on employee equity. The roughly $31 million between the two is the part of the non-GAAP margin that has nothing to do with stock compensation. Both versions exclude a cost that produced 1.82% share dilution in six months with no offsetting repurchase.
3. Cash Flow
| Item (six months) | H1 2025 ($M) | H1 2026 ($M) | Change % |
|---|---|---|---|
| Operating cash flow | 471.6 | 650.5 | +37.9 |
| Investing cash flow | (634.5) | (664.7) | — |
| Financing cash flow | (603.8) | 51.5 | — |
| Free cash flow | 409.7 | 567.8 | +38.6 |
| Ending cash | 489.0 | 435.0 | — |
Free cash flow, defined by the company as operating cash flow less both property purchases ($21.2 million) and capitalized software ($61.5 million), reached $567.8 million — a 26.7% margin, up from 25.8%. Total capital intensity held at 3.9% of revenue, though the mix shifted decisively: hardware spending fell 11.1% while capitalized software rose 61.9%.
Earnings quality by the conventional measure looks extraordinary — operating cash flow covers net income 6.70 times. That ratio is not a sign of exceptional collections; it is arithmetic driven by the $417.1 million SBC add-back, which alone is 4.3 times net income, plus the $155.1 million payables swing discussed above. The more useful figure for a subscription business is free cash flow less stock compensation: $150.7 million, a 7.1% margin, against $65.0 million and 4.1% a year earlier. Genuine improvement, but an order of magnitude below the headline FCF margin.
Stock compensation was 19.6% of revenue, down from 21.7% — the direction is right: SBC grew 21.0% while revenue grew 34.0%, so the charge is being diluted by growth rather than cut in absolute terms. Financing cash flow swung positive simply because the prior-year period included the $635.5 million repayment of the 2025 convertible notes.
4. What Deserves Closer Attention
Contracted backlog has stalled since December. Remaining performance obligations were $3,471.4 million at June 30, versus $3,461.2 million at year-end — a 0.3% increase over six months. Year over year the comparison is strong, up 43.1% from $2,425.8 million and outpacing revenue growth. But the entire gain was booked in a single quarter: RPO jumped 24.2% in Q4 2025 alone, then declined slightly from $3,484.4 million at March 31. Datadog books much of its revenue on usage-based drawdown contracts, and the filing warns explicitly that revenue timing on those contracts is uncertain — so RPO is a weaker signal here than at a pure committed-subscription vendor. Still, the pattern suggests a concentration of large multi-year commitments signed in late 2025 that has not yet repeated.
Billings tell a healthier story than RPO. Revenue plus the change in deferred revenue implies first-half billings of roughly $2.20 billion against $1.60 billion, growth of 38.1% — faster than the 34.0% revenue growth. Read together, the two metrics point to strong near-term billing momentum alongside shortening contract duration rather than weakening demand.
Growth is expansion, not acquisition. Customer count reached approximately 33,400 from 31,400, up just 6.4%, while revenue per customer rose 27.5%. Customers generating $100,000 or more of annual run-rate revenue grew 22.6% to 4,720 and now represent 91% of ARR, up from 89%. The land-and-expand engine is working on existing accounts; new logo acquisition is close to flat. Rising ARR concentration — 91% of ARR now sits with the 14% of customers spending $100,000 or more, up from 89% and 12% a year ago — raises the stakes on retention among a few thousand accounts.
That concentration risk is not hypothetical — it has already fired. On the Q2 call, management disclosed that its largest customer, an AI-native business, is reducing usage beginning in Q3, and said it has fully derisked that account in guidance for the remainder of the year. This is the single most consequential disclosure of the quarter, and it is not visible anywhere in the balance sheet or income statement above. Its effect appears in guidance instead: Q3 revenue is guided to $1.135–$1.145 billion, implying roughly 28–29% year-over-year growth against the 35.6% just delivered. Full-year 2026 revenue is guided to $4.45–$4.47 billion, about 30% growth. Datadog beat on revenue, beat on EPS and raised the full-year outlook — and the stock still fell roughly 17–19% on August 6, because the market read the largest-customer cut as evidence that AI-native buyers optimize their observability spend once workloads mature. Anyone reading the Q2 acceleration as a trend should read the Q3 guide alongside it.
Growth is also increasingly American. North America revenue rose 40.6% to $824.7 million while international grew 23.6% to $296.8 million, cutting the international share from 29.0% to 26.5%. US revenue alone rose 41.2%. Geographic diversification is moving backwards.
A deferred tax asset sits unrecognised. The effective tax rate was 13.9% for the quarter and 12.2% for the half, well below statutory, because a full valuation allowance is maintained against substantially all US net deferred tax assets. Management states realization is not more likely than not. Sustained profitability would eventually force a reassessment, and releasing that allowance would produce a large one-off increase in net income unrelated to operations. The filing also flags the One Big Beautiful Bill Act, enacted July 2025, which reverses mandatory capitalization of domestic R&E expenses — materially relevant for a company spending $478 million a quarter on R&D, and a factor in any future valuation-allowance judgement. Cash taxes paid, meanwhile, doubled to $23.6 million.
Governance changed quietly. Datadog completed its reincorporation from Delaware to Nevada on April 21, 2026. The dual-class structure remains, with 24.5 million Class B shares outstanding against 334.4 million Class A. Legal contingencies are unremarkable — the company reports no proceedings expected to have a material adverse effect, and no reasonably possible loss ranges are disclosed.
5. Key Implications
What grew. Revenue growth of 35.6% beat the 32.2% posted in Q1 2026, and both are well above the rates Datadog was printing two years ago — 26.7% in Q2 2024, per prior filings. That is an unusual pattern at this scale. But it should be described as what it is: two quarters of sequential improvement visible in this filing, not a long verified streak. The intervening quarters are not in this 10-Q, and the company's own Q3 guide of 28–29% says the sequence stops here.
What actually carried earnings. Operating expense discipline delivered 6.1 points of leverage, offset by 1.34 points of gross margin erosion, for a 4.78-point operating margin improvement. That is real. But it lifted GAAP operating income only to $5.5 million on $1.12 billion of revenue. Ninety percent of pre-tax income came from the securities portfolio, and that portfolio's yield is falling — interest income declined year over year in both the quarter and the half despite an 11.4% larger balance. Strip out the treasury and Datadog is approximately break-even at the operating line.
What to watch. Three things, in order. First, the largest-customer usage reduction and whether it proves idiosyncratic or the leading edge of AI-native customers optimizing observability spend — the 91%-of-ARR concentration means this question dominates the others. Second, gross margin, which has now compressed four consecutive readings in the table above and is the mechanism by which compute costs eat operating leverage before it reaches the bottom line. Third, RPO, which has been flat for six months after a single strong Q4 2025; another flat quarter would make the billings-versus-backlog divergence harder to read as shortening duration rather than softening commitment.
The honest summary. This is a business converting scale into operating leverage faster than most software companies its size, while its reported profitability still depends on interest rates rather than its own operations, and while its largest customer has just told it to expect less. The Q2 numbers are good. The Q3 guide is the more informative document.
