Arista Networks sells equipment, software and support that help move data through cloud, artificial-intelligence and business networks. In the second quarter ended June 30, 2026, operating profit rose 39.7% from a year earlier, outpacing sales growth even as more sales went to large customers that generally receive bigger discounts. Supporting future demand also meant larger supplier commitments: non-cancellable purchase orders reached $9.7 billion, up from $6.8 billion at year-end. Arista has the finances to expand, but must turn those purchases into systems customers accept and sales that preserve its margins.
Reporting basis: This analysis covers Arista Networks, Inc. and its wholly owned subsidiaries under U.S. GAAP. Second-quarter results mean April–June; first-half results mean January–June. Balance-sheet comparisons are June 30, 2026 versus December 31, 2025. The information cutoff is August 5, 2026, the selected filing’s submission date; later operating developments are excluded.

1. More network sales are producing more profit despite discount pressure
Arista earned more operating profit from each revenue dollar because operating expenses grew more slowly than sales. Operating profit is what remains after product costs and the expenses of running the business, before investment income and taxes. Arista spread its engineering, selling and administrative costs across much larger sales.
Customers primarily pay Arista for switching and routing platforms. Switches connect devices within networks, while routers direct traffic between networks. Arista’s Extensible Operating System, or EOS, supplies the software that runs those products. Customers also purchase support, repairs and software updates, usually through contracts lasting one to three years.
Second-quarter product revenue rose 38.8% to $2,605.2 million, compared with $1,877.0 million a year earlier. Management attributed the increase to higher shipments across its customer base. Service revenue rose 31.3% to $430.5 million as the installed base expanded and customers bought new support contracts or renewed existing ones. Product sales supplied $728.2 million of the quarter’s $830.9 million revenue increase.

Gross margin measures the revenue left after the direct costs of products and services. The main source of pressure was specific: management said a larger proportion of sales went to large end customers that generally receive higher discounts. Calculated product gross margin fell from 62.3% to 59.8%. Service gross margin was much steadier, at 81.9% versus 82.0%. Support therefore left more revenue after direct costs than hardware did, measured as a percentage of sales. But hardware dominated revenue, so service growth could not prevent the overall gross-margin decline.
The filing identifies higher shipments and the shift toward large customers, but does not quantify separate price, volume and product-mix effects.
Operating expenses rose 17.7%, compared with revenue growth of 37.7%. That was enough to lift operating margin by a calculated 0.66 percentage points despite a 2.32-point gross-margin decline. In dollars, the quarter’s $471.7 million increase in gross profit exceeded the $79.9 million increase in operating expenses, leaving $391.8 million more operating profit.
The company was still investing. First-half research and development expense increased to $691.9 million from $562.9 million. Management identified $59.4 million more personnel expense and $58.8 million more new-product introduction costs as major drivers. Sales and marketing rose to $291.9 million from $243.1 million, principally because of hiring. The improved operating margin therefore came alongside greater development and selling activity.

The longer history supports genuine business expansion. Annual revenue increased from $5,860.2 million in 2023 to $7,003.1 million in 2024 and $9,005.7 million in 2025: growth of 19.5% and 28.6%, respectively. Separately, first-half 2026 revenue grew 36.5% against the same six months of 2025. The latest growth follows an already expanding business.
Geography adds an important qualification. The Americas supplied $1,305.4 million of the first half’s $1,535.1 million revenue increase. Europe, the Middle East and Africa added $217.0 million, while Asia-Pacific added only $12.7 million. Second-quarter Asia-Pacific revenue improved more strongly, reaching $259.6 million versus $199.1 million. The business is growing internationally, but the first-half expansion remained heavily tied to shipments in the Americas.
Reporting basis: Geographic revenue follows customers’ shipping addresses, not customer headquarters or ultimate use. Arista reports one operating segment; it does not provide separate AI, campus or cloud operating profits. VeloCloud was acquired on June 30, 2025, so the periods also differ in acquisition scope. The disclosed information does not support labelling total growth “organic.”

2. Customer acceptance increasingly determines when shipments become sales
A growing amount of customer activity is waiting to become reported revenue. That gives Arista future business to work through, but it also makes the timing of customer tests and acceptance more important to quarterly results.
Three different arrangements affect when customer activity becomes revenue. They are not consecutive steps in every sale. First, Arista can place equipment with a customer for evaluation. Arista still owns it, and the customer is invoiced only if the trial finishes successfully and the equipment is accepted. Evaluation inventory increased from $403.7 million at year-end to $616.0 million in June. It represented about one-quarter of total inventory at June 30.
Second, a contract can contain customer-specific acceptance requirements that prevent revenue recognition even after shipment. Revenue held back under these arrangements forms part of deferred revenue. Arista also holds back the related product costs until the sale qualifies for recognition. Current deferred cost of goods sold rose from $1,197.0 million to $1,621.9 million, which the filing links to higher deferred product revenue.
Third, customers buy support covering future periods. Arista recognizes that revenue over the contract’s life as it provides the service. This also creates deferred revenue, but its release follows service delivery rather than a single equipment-acceptance event.
| Customer delivery and recognition measures; U.S. dollars in millions | December 31, 2025 | June 30, 2026 |
|---|---|---|
| Evaluation inventory, included in total inventory | 403.7 | 616.0 |
| Current deferred cost of goods sold | 1,197.0 | 1,621.9 |
| Deferred revenue, current and non-current | 5,372.4 | 6,865.9 |
| Separate cancellable-contract liabilities | 250.1 | 278.4 |
Sources: Second-quarter 2026 Form 10-Q, Note 3, pages 9–10; 2025 Form 10-K, Note 1, inventory valuation and revenue-recognition policies, pages 75 and 77–78.
Deferred revenue is turning into sales, rather than simply accumulating. Arista recognized $2,212.5 million from the opening deferred-revenue balance during the first half, compared with $735.8 million a year earlier. But $3,706.0 million of new deferrals remained unrecognized at June 30. That exceeded the amount released and lifted the ending balance by $1,493.5 million.
The company also reported $278.4 million of customer payments under cancellable contracts as a separate category of contract liabilities. These amounts sit within other liabilities, not within the deferred-revenue lines. Their separate presentation reflects different customer rights and transaction stages.
Including those two categories and other future obligations, Arista disclosed approximately $8.4 billion of revenue expected to be recognized in future periods. About 91% was expected within two years. The total includes $427.8 million of unbilled support and service contracts and $875.1 million of binding agreements primarily related to future product shipments.
This is meaningful visibility, but it is not a single pool of equipment orders ready to ship next quarter. It combines delivered products awaiting acceptance, future support and future shipments. Nor does deferred revenue equal cash already collected: some billings can still sit in accounts receivable.
Management explicitly connects more customer trials and acceptance clauses with new products and new AI Ethernet uses. It also warns that failed trials can lead to returns and inventory write-downs. The useful business conclusion is that Arista has substantially more customer deployment activity in progress, while successful qualification determines how much of that activity becomes profit and when.

3. Cash generation is strong, with a substantial contribution from payment timing
Operating cash comfortably covered purchases of property and equipment, helped by deferred revenue and taxes not yet paid. Those timing benefits are real sources of funding, but they are different from profit earned on completed sales.
First-half operating cash flow increased to $2,776.5 million from $1,841.8 million. Net income increased by $533.2 million over the same period. The rest of the $934.7 million cash-flow improvement came from changes in noncash adjustments and operating assets and liabilities.
| Profit-to-cash reconciliation; U.S. dollars in millions | First half 2025 | First half 2026 |
|---|---|---|
| Net income | 1,702.6 | 2,235.8 |
| Noncash adjustments, net | -154.1 | 64.3 |
| Operating asset and liability movements, net | 293.3 | 476.4 |
| Operating cash flow | 1,841.8 | 2,776.5 |
| Cash purchases of property and equipment | 52.4 | 84.2 |
| Free cash flow, calculated | 1,789.4 | 2,692.3 |
Reporting basis: Free cash flow here is operating cash flow less cash purchases of property and equipment. It excludes securities purchases, acquisitions and other investing outflows. It is a calculated measure, not a substitute for the full cash-flow statement.
Source: Second-quarter 2026 Form 10-Q, cash-flow statement, page 5, and “Cash Flows from Operating Activities,” page 20.
The largest positive operating movement was the $1,493.5 million increase in deferred revenue. However, other assets absorbed $619.7 million, primarily because product costs were being held for sales whose revenue was also deferred. These two statement lines together contributed $873.8 million. The second line includes other assets too, so this is a combined accounting contribution, not a precise measure of cash received on product deposits.
Growth also required funding customers and inventory. Accounts receivable consumed $379.3 million as product and service billings increased. In everyday terms, Arista had recorded more amounts due from customers that had not yet been collected. Inventory absorbed another $288.2 million as the company carried more components and finished products. Suppliers provided only $40.9 million of additional funding through accounts payable, compared with $160.0 million a year earlier.
Tax payment timing helped by $198.4 million. Arista owed more income tax at the end of the half; those future payments left more cash in the business during this period. Other liabilities supplied another $30.8 million, completing the $476.4 million net operating-balance contribution.
Arista added back $241.3 million of stock compensation and $46.7 million of depreciation and amortization because these expenses reduced profit without equivalent current-period operating cash payments. Conversely, the $213.1 million deferred-tax adjustment removed a tax benefit included in profit that did not itself bring in cash during the half. Management associated that movement primarily with increased deferred revenue. Other noncash adjustments reduced the reconciliation by $10.6 million.
Sources: Second-quarter 2026 Form 10-Q, cash-flow statement, page 5, and liquidity discussion, page 20.
Most investing cash went into financial assets. Arista bought $4,328.9 million of marketable securities and received $2,003.0 million from maturities and sales, for a net securities outflow of $2,325.9 million. Adding $84.2 million of property and equipment purchases and $35.0 million of other investing outflows gives total investing cash use of $2,445.1 million. There was no acquisition cash payment in this half, versus $300.0 million a year earlier.
Financing used just $1.5 million. Employee equity plans brought in $33.4 million, while net-share-settlement tax withholding used $31.2 million and other financing used $3.7 million. Arista paid no dividends and made no open-market or programme share repurchases during the period.
After a negative $3.6 million currency effect, cash, cash equivalents and restricted cash increased by $326.3 million to $2,291.6 million. The balance sheet’s cash and cash equivalents line shows $2,290.2 million; the $1.4 million restricted portion is included separately in other assets. Most of the increase in combined cash and securities came from securities. Arista used much of its free cash flow to buy those investments, explaining why cash and cash equivalents rose much less.

4. Supplier commitments create a larger operating exposure than borrowing
Arista’s principal funding challenge is supporting promised purchases and unfinished customer deployments, rather than refinancing debt. Its cash and securities provide a large buffer, while the scale and timing of future component deliveries deserve close attention.
Arista outsources most manufacturing. Management said it increased purchase commitments to support rapid AI network deployment, secure supplies in tightening memory and silicon markets, and shorten delivery times. Committing before future demand is certain improves its ability to supply customers. It also leaves Arista exposed if customers delay, change their network designs or buy less than expected.
Non-cancellable purchase commitments increased from $6.8 billion at December 31 to $9.7 billion at June 30. The June amount included $9.4 billion with expected receipt dates within twelve months and $0.3 billion after that. Supplier agreement is required to reschedule or adjust these legally binding orders. Expected receipt dates describe when goods or services arrive; they are not a detailed cash-payment schedule.
These orders are not yet recorded as ordinary balance-sheet liabilities. They should not be treated as existing bank debt, but neither should they disappear from a liquidity assessment. Customer remaining performance obligations cannot simply be subtracted from them: the two totals have different timing, cancellation provisions, cost bases and product or service content.
| Funding and operating exposure; U.S. dollars in millions | December 31, 2025 | June 30, 2026 |
|---|---|---|
| Cash and cash equivalents | 1,963.9 | 2,290.2 |
| Marketable securities | 8,779.1 | 11,053.1 |
| Combined cash and securities, calculated | 10,743.0 | 13,343.3 |
| Accounts receivable, net | 1,886.9 | 2,266.2 |
| Inventory | 2,247.1 | 2,535.3 |
| Supplier deposits securing commitments | 53.0 | 124.4 |
| Non-cancellable purchase commitments, rounded | 6,800 | 9,700 |
Sources: Second-quarter 2026 Form 10-Q, balance sheet and Notes 3 and 5, pages 1, 9 and 12; 2025 Form 10-K, Note 5, pages 85–86. The annual commitment description also includes licences, property and equipment, and other corporate purchases; the quarterly description emphasizes finished goods and strategic components.
Raw materials supplied most of the inventory increase, rising from $611.2 million to $859.6 million. Finished goods increased much less, from $1,635.9 million to $1,675.7 million, despite the rise in evaluation inventory within that category. The company is therefore carrying both more production inputs and more products undergoing customer trials. These balances represent different stages of its effort to supply demand.
Past losses show why forecasting matters. Inventory write-downs were $234.4 million in 2023, $267.2 million in 2024 and $131.6 million in 2025. Arista also recorded $113.0 million of supplier-liability charges in 2023; those charges were not material in 2024 or 2025. These are annual expenses, not first-half 2026 charges or estimates of future losses. They demonstrate that strong sales growth can coexist with costs from buying the wrong quantities or products.
The strongest counterweight is liquidity. Combined cash and securities increased by $2,600.3 million during the half. Of the $11,053.1 million securities portfolio, $4,365.2 million was due to mature within a year and $6,687.9 million within one to three years. Arista classifies the whole portfolio as current because it is available to support operations, even though most of it does not mature within twelve months.
The statements disclose no bank or bond borrowing balance and no material financing-debt maturity, interest-payment or covenant schedule. Operating leases still require payments. The latest detailed annual disclosure put remaining lease obligations at $90.5 million on December 31, 2025, with $22.1 million payable within the following twelve months. The selected 10-Q does not replace that with a new June lease schedule, so those figures remain explicitly year-end amounts.
Liquidity supports expansion, but it does not eliminate product risk. Paying suppliers is manageable with the disclosed resources; selling their output at acceptable margins depends on delivery schedules, customer acceptance and product relevance. Arista’s predominant switching-chip supplier is Broadcom. Concentrated supply makes the quality and timing of that relationship especially important when memory and silicon availability tighten.

5. The balance sheet is expanding mainly around customer delivery and retained profit
Most of the balance-sheet growth reflects more liquid investments, more business awaiting completion and profit retained inside Arista. Physical expansion is real, but it is a much smaller use of capital than the supply chain and financial portfolio.
Total assets rose by $4,271.5 million to $23,720.1 million. Cash and securities supplied $2,600.3 million of that increase. Receivables, inventory and current deferred product costs explain much of the remaining growth already discussed. Prepaid expenses and other current assets increased by $508.6 million, of which $424.9 million was the increase in current deferred cost of goods sold.
Property and equipment increased to $312.5 million from $203.1 million. Construction in progress rose to $213.5 million from $107.9 million. Arista is building office, laboratory and data-center space in Santa Clara to support its operations and development work.
At June 30, management expected another $110.0 million to $135.0 million of spending on that project through completion at the end of 2026. This is a remaining project estimate, not total company capital expenditure guidance. Cash equipment purchases and changes in net property balances also measure different things: payments occur on their own schedule, while asset balances reflect additions and depreciation.
Goodwill was unchanged at $416.1 million. Acquisition-related intangible assets declined from $288.8 million to $258.2 million through $30.6 million of amortization. These assets include acquired technology and customer relationships. Their expense continues after the acquisition payment, illustrating why acquisition cash outflows and their later effect on profit fall in different periods.
The $300.0 million VeloCloud acquisition in June 2025 was intended to add secure wide-area networking that connects customer sites, complementing Arista’s data-center and campus products. Its purchase allocation included $268.4 million of intangibles and $148.0 million of goodwill, offset by $116.4 million of net tangible liabilities. This broadens what Arista can sell to businesses, but the filing does not isolate VeloCloud’s revenue or profit contribution.
Source: Second-quarter 2026 Form 10-Q, balance sheet and Notes 3–5, pages 1 and 9–12.
Deferred tax assets increased from $1,773.6 million to $2,001.6 million. They represent tax benefits expected to be used in future periods, rather than cash available to pay suppliers now. Other assets increased from $668.8 million to $826.5 million even as acquisition intangibles declined. The cash-flow discussion identifies deferred product costs as the main driver of higher operating other assets, but it does not provide a complete separate bridge for every non-current balance.
Liabilities rose by $1,844.3 million to $8,922.4 million. Deferred revenue contributed $1,493.5 million, making unfinished customer obligations the dominant source of the increase. Other current liabilities rose by $291.6 million, while accounts payable rose by $41.0 million and accrued liabilities by $11.2 million. The operating cash-flow reconciliation separately identifies tax-payable timing, but it should not be mistaken for a complete composition table of other current liabilities.
Equity increased by $2,427.2 million to $14,797.7 million. Retained earnings rose by $2,236.2 million: $2,235.8 million of net income plus a $0.4 million entry labelled “other.” Additional paid-in capital increased by $243.5 million, reflecting stock compensation and employee share issuance, less tax withholding on settled awards.
Accumulated other comprehensive income moved from positive $12.0 million to negative $40.5 million. The $52.5 million change comprised securities-related movements of negative $49.5 million and currency translation of negative $3.0 million. These items reduced equity outside net income. Arista recorded no securities credit losses or impairments during the half, so the portfolio movements should not be described as losses on failed borrowers.

6. Higher earnings came from the business, with tax and share compensation affecting the result
Reported profit grew strongly despite a higher tax rate. The operating gains reached net income even after the full expense of employee share awards and a larger tax provision.
First-half net income rose 31.3%, less than the 37.4% increase in operating profit. The effective tax rate increased from 16.3% to 19.5%, primarily because tax benefits associated with equity compensation declined. In the second quarter alone, the rate increased from 17.7% to 19.4%. Employee award activity therefore affects more than the compensation expense: it can also change tax deductions and the final tax provision.
Interest income provided another source of earnings. It increased to $231.5 million in the half from $180.6 million, which management attributed to larger cash and securities balances. This income comes from the financial portfolio rather than selling network products. It adds to pretax profit; future amounts depend on interest rates and how much liquidity remains invested.
Stock compensation increased to $241.3 million from $178.2 million in the first half. It is included in all reported profit figures used here. Although added back in operating cash flow, it remains payment for employees’ work and can increase the number of shares over which earnings are divided. At June 30, Arista had $1.5 billion of unrecognized compensation costs expected to enter expense over a weighted-average 3.9 years.
Outstanding shares increased from 1,256.5 million to 1,261.2 million. Employee plans issued 4.9 million shares, partly offset by 0.2 million shares withheld for tax settlement. There were no programme repurchases during the half, compared with $983.0 million of cash repurchases in the comparable 2025 period. Buybacks can offset employee share issuance, but they also use cash available to fund the business. Arista preserved that cash this half while its share count increased; the filing does not explain why management made no programme repurchases. The remaining $817.9 million authorization is optional, not a future cash obligation.
Second-quarter diluted weighted-average shares rose from 1,271.2 million to 1,276.0 million. Reported diluted EPS nevertheless increased from $0.70 to $0.95 because profit grew much faster than the share count. First-half diluted shares were nearly unchanged year over year. Arista’s earlier repurchased shares were retired, with repurchase costs reducing retained earnings; they were not left as a separate treasury-share balance.

7. Arista must win network choices, not just benefit from AI spending
Arista’s next opportunity depends on useful products and successful customer deployments in a highly competitive market. More spending on AI creates a need to connect processors, but customers can choose different network suppliers and architectures.
The company’s June 9 announcement gives a concrete view of its response. Arista introduced the 7060XE7 family with 1.6-terabit Ethernet connections, Broadcom Tomahawk 6 switching silicon and support for EOS or open network operating systems. The purpose is to move more data while accommodating dense racks and different cooling designs. Microsoft described collaboration for Azure Maia and Fairwater, while Meta and Oracle also supplied supporting statements. These are evidence of technical engagement, not disclosed purchase amounts.
Timing limits the immediate revenue implication. The announcement scheduled air-cooled 1.6-terabit products for the fourth quarter of 2026, and liquid-cooled and 128-port 800-gigabit versions for the first quarter of 2027. Those planned releases help explain continuing engineering investment; they should not be credited with the second quarter’s already reported revenue.

Competition extends beyond another standalone switch. NVIDIA’s January 5 Rubin announcement combined processors, networking and related components within a coordinated platform, including Spectrum-6 Ethernet. That gives customers an alternative route to building an AI system. The business implication is that Ethernet adoption alone does not establish how much revenue Arista will capture: the network supplier is still a customer choice.
Source: NVIDIA, Rubin platform announcement, January 5, 2026, platform components and Spectrum-X Ethernet discussion.
Arista’s filing also identifies Cisco, Hewlett Packard Enterprise, NVIDIA and vendors using open-source operating systems among competitors. Arista’s response centers on consistent software, automation and reliable network operation. These features matter because equipment that operators can manage and troubleshoot across a large installation can reduce deployment complexity. Its challenge is to demonstrate that value while large buyers negotiate discounts and alternatives become more complete.
Customer concentration reinforces this tension. Two customers represented a combined 42% of annual revenue in 2025, compared with 35% in 2024 and 39% in 2023. These are annual figures, not a disclosed second-quarter 2026 concentration measure. Large customers can fund substantial growth, but their deployment schedules, testing and bargaining power can also affect the entire company’s margins and quarterly timing.
The August 4 earnings release projected approximately $3.3 billion of third-quarter revenue, a calculated 8.7% increase from the second quarter. That was management’s forecast at the cutoff, not a reported outcome. The filing says some current shipments serve previously committed deployment plans and may be accelerated. Together, those disclosures support continued near-term activity while explaining why one quarter’s shipment growth is an imperfect measure of new demand.
Sources: Second-quarter 2026 Form 10-Q, management overview, pages 15–16, and competition risks, pages 31–32; August 4, 2026 earnings release, “Financial Outlook.”
Legal and tax exposures add another possible demand on resources. The June filing describes intellectual-property disputes and other proceedings, with no significant recorded provisions and no estimable additional loss amount. Management considered the unresolved matters unlikely to have a material adverse effect, while acknowledging that an unfavorable outcome could still be material. Separate customer indemnities may require repairs, replacement products or refunds.
The latest detailed annual tax note reported $191.7 million of gross unrecognized tax benefits at December 31, 2025, of which $100.7 million would affect the effective tax rate if recognized. These are uncertain tax positions, not a forecast cash settlement, and the 10-Q does not provide a replacement June roll-forward. Alongside these less predictable exposures, the more immediate disclosed business pressure remains supply availability and costs. Tariffs and scarce components could reduce margins further if Arista cannot pass the costs to customers.
Sources: Second-quarter 2026 Form 10-Q, Note 5, page 12, macroeconomic discussion, page 16, and tax risks, pages 46–47; 2025 Form 10-K, Note 8, page 93.
8. The business can finance expansion; matching purchases to accepted sales is the decisive test
Arista enters its next product cycle with strong earnings and funding, but greater exposure to customer deployment decisions. The improvement is substantive: reported operating margins increased while the company spent more on engineering and sales. It generated enough operating cash to cover purchases of property and equipment, and its cash and securities increased without new disclosed bank or bond borrowing.
The next stage places more weight on coordination. Arista is securing components ahead of demand, placing more equipment in trials and waiting for acceptance on a larger pool of customer arrangements. Successful deployment converts those commitments into sales and supports subsequent service revenue. Delays or changed specifications can instead extend the time cash is tied up, leave unwanted inventory and pressure margins.
The overall business assessment is therefore favorable on operating capacity and financing strength, with a specific constraint on growth quality: customer acceptance must keep pace with the company’s much larger supply commitments. Strong cash gives Arista time to deliver. It does not replace the need to sell the right systems, on the right schedule, at margins that preserve the operating gains already achieved.

- Filing identity: Arista Networks, Inc.; CIK 0001596532; Form 10-Q; accession 0001596532-26-000175; filed August 5, 2026; reporting date June 30, 2026. The signature date is August 4 and is distinct from the filing date. Identity was checked against the SEC submissions record.
- Source scope: The complete second-quarter 2026 Form 10-Q is the foundation. The 2025 Form 10-K, accession 0001596532-26-000013, supplies accounting policies and explicitly dated annual comparisons. Page references above are the documents’ printed pages.
- XBRL checks: SEC company facts match the selected accession’s consolidated revenue, net income, operating cash flow, assets, liabilities and equity. This cross-check uses structured data from the same filing. Tags checked include
us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax,NetIncomeLoss,NetCashProvidedByUsedInOperatingActivities,Assets,LiabilitiesandStockholdersEquity. Dollar facts were converted to millions. April 1–June 30 and January 1–June 30 duration contexts were kept separate; balance-sheet facts use instant contexts. Annual history uses January–December contexts in the 2025 10-K. - Growth and margins: Growth equals current-period amount divided by the comparable prior-period amount, minus one. Margin equals the applicable profit divided by revenue. Second-quarter product gross margins are (2,605.2 − 1,047.5) ÷ 2,605.2 = 59.8% for 2026 and (1,877.0 − 707.3) ÷ 1,877.0 = 62.3% for 2025. Service gross margins are (430.5 − 77.9) ÷ 430.5 = 81.9% and (327.8 − 58.9) ÷ 327.8 = 82.0%, respectively. Dollar inputs are in millions and come from the consolidated income statements on page 2 of the selected 10-Q. Percentage-point movements use unrounded calculated margins.
- Cash reconciliation: First-half 2026 operating cash is 2,235.8 + 64.3 + 476.4 = 2,776.5 million dollars. The prior comparison is 1,702.6 − 154.1 + 293.3 = 1,841.8 million dollars. Free cash flow subtracts cash capital spending of 84.2 and 52.4, respectively. Closing cash including restricted cash is 1,965.3 + 2,776.5 − 2,445.1 − 1.5 − 3.6 = 2,291.6 million dollars. Restricted cash is 1.4 million dollars at both opening and closing.
- Deferred revenue: 5,372.4 − 2,212.5 + 3,706.0 = 6,865.9 million dollars. Current-period additions exclude amounts recognized in that same period. The prior first-half bridge is 2,791.4 − 735.8 + 2,006.1 = 4,061.7 million dollars. Disclosed future-revenue components total 6,865.9 + 278.4 + 427.8 + 875.1 = 8,447.2 million dollars, reported as approximately 8.4 billion.
- Equity and balance-sheet checks: Paid-in capital reconciles as 2,911.8 + 241.3 + 33.4 − 31.2 = 3,155.3 million dollars. Retained earnings reconcile as 9,446.6 + 2,235.8 + 0.4 = 11,682.8 million dollars. Total equity reconciles as 12,370.5 + 2,235.8 + 241.3 + 33.4 − 31.2 − 52.5 + 0.4 = 14,797.7 million dollars. June assets equal liabilities plus equity: 23,720.1 = 8,922.4 + 14,797.7. December assets likewise reconcile: 19,448.6 = 7,078.1 + 12,370.5. The accounts-payable balance movement and cash-flow line differ by 0.1 million dollars; each is retained as reported.
- Forecast calculation: The third-quarter revenue comparison is 3,300.0 ÷ 3,035.7 − 1 = 8.7%, using management’s approximate forecast. Product release dates and construction completion remain management plans.
