Block’s personnel costs fell by $250.6 million from a year earlier across the three operating-expense lines where its third-quarter 10-Q itemises them, by our arithmetic, while software and cloud computing infrastructure fees rose by $93.8 million. The 10-Q, filed on 3 November, says the fee increase was “primarily due to higher software license costs, including AI-related tools, and higher data center fees”.
By our arithmetic, that is about 37 cents of new software and cloud fees for every dollar of personnel cost removed. Block says it reduced its workforce by more than 40% under a plan announced in February 2026.
Over the same year, Adjusted Operating Income rose by $442.6 million while gross profit rose by $573.7 million. By our arithmetic, 77% of the gross-profit gain reached Adjusted Operating Income.
Business Pill · Operating Leverage
An evergreen Business Engineer explainer on why profit can grow faster than sales. It teaches the general idea only and does not discuss Block.
The key insight: By our arithmetic, Block’s personnel costs fell by $250.6 million across three expense lines while software and cloud fees rose by $93.8 million, about 37 cents for every dollar removed; Adjusted Operating Income captured 77% of the year’s $573.7 million gross-profit gain.
Gross profit was $3.235 billion in the quarter to 30 September, up 22% from $2.662 billion, according to Block’s third-quarter shareholder letter. Revenue was $6.719 billion. Cash App gross profit was $2.070 billion, up 27%, and Square gross profit was $1.157 billion, up 14%.
Adjusted Operating Income, a non-GAAP measure, was $923 million, up 92%, with a 29% margin on gross profit. Adjusted Diluted EPS was $1.13, up 109%, and Adjusted EBITDA was $1.228 billion.
On a GAAP basis, operating income was $428 million, up 5%, and diluted earnings per share were $0.92, up 24%. Net income attributable to common stockholders was $566 million.

Announcements: 🔹 Square Features: Over 180 released through the first three quarters 🔹 Neighborhoods: Over 30K new seller locations; nearly $5B annualized GPV 🔹 Squaremates: Generally available in the U.S. 🔹 Square Kiosk: New voice-enabled AI self-ordering device
Wall St Engine (@wallstengine), an account that posts earnings figures on X, posted Block’s third-quarter highlights at 21:14 UTC on 3 November, less than two minutes after the SEC accepted the 8-K carrying the shareholder letter (21:12:52 UTC). The figures we checked, including gross profit of $3.24 billion, Adjusted Operating Income of $923 million and Cash App gross profit of $2.07 billion, match the letter, some as roundings; the estimates it cites are not verified by us. The post lists Cash App inflows of $86.00 billion against an estimate of $89.47 billion as its one red mark. It does not show the personnel and software lines or the DOJ accrual this piece is built on.
Where the Workforce Cut Shows Up
The 10-Q says personnel costs in product development fell by $149.9 million, “primarily from cost efficiencies realized following the implementation of the Workforce Plan actions in the first quarter of 2026”. In general and administrative expenses, personnel costs fell by $130.2 million; the filing ties that partly to an in-person company event held in the third quarter of 2025.
In sales and marketing, personnel costs rose by $29.5 million, which the filing says mainly reflects higher sales commissions as Block scales its Square field sales team. Netting the three lines gives the $250.6 million decline, by our arithmetic.
Product development expenses fell 11% overall, to $635.6 million from $711.2 million. Restructuring charges for the Workforce Plan were $495.0 million in the first nine months of 2026, with none in the third quarter. Block says it expects annualized net cost savings of about $800 million to $900 million, “a portion of which we are strategically reinvesting in the Company”.
What Block Says It Is Doing With AI
The 10-Q says the plan has resulted in “an increased reliance on automation, proactive intelligence capabilities and AI tools that we believe will enhance productivity and maintain operational efficiency”. The letter says that “In recent weeks, AI has been autonomously reviewing and merging an increasing number of our production code changes related to low-risk, routine work”.
The letter says Block released over 180 new Square features in the first three quarters, more than in 2024 and 2025 combined. It says Block began piloting Buzz, its internal AI collaboration environment, with prospective customers in October, and that “we expect to generate our first machine intelligence revenue in the fourth quarter”.
For sellers, Block launched Squaremates, its renamed AI product for Square sellers, which the letter says is generally available in the U.S., and the Square Kiosk, a self-ordering device it says was “built from the ground up around voice-enabled AI”.
Cash App: Gross Profit Outran Inflows
Cash App gross profit grew 27%, while total Cash App inflows grew 10%, to $86 billion, the letter shows. Monthly transacting actives grew 4%, to 60 million, and inflows per transacting active grew 6%, to $1,446.
Block reports a Commerce Enablement monetization rate of 1.74%, up 18 basis points from 1.56% a year earlier, which it attributes to “higher BNPL adoption on Cash App Card through Afterpay Post-Purchase and Pre-Purchase”. Consumer lending origination volume grew 40%, to $19.0 billion.
General and administrative expenses rose by $303.5 million, or 56%. The 10-Q says the increase was primarily driven by a $421.1 million increase in accrued expenses for estimated and settled amounts in certain litigation and regulatory matters.
One is a U.S. Department of Justice inquiry. The 10-Q says Block and the DOJ reached an agreement in principle in October to resolve it through a deferred prosecution agreement. Under it, the DOJ would defer for three years “a charge that the Company failed to maintain an effective anti-money laundering program in violation of the Bank Secrecy Act”. The filing puts the net monetary payment at about $764 million, which Block has accrued, and says the resolution remains subject to a final agreement and court approval.
Transaction, loan and consumer receivable losses rose by $238.3 million, or 66%, to $601.7 million.

The Guidance
For the fourth quarter, Block guides to gross profit of $3.315 billion, Adjusted Operating Income of $1.005 billion and Adjusted Diluted EPS of $1.15. For 2026, it raised its outlook to gross profit of $12.626 billion, up 22%, Adjusted Operating Income of $3.519 billion, a 28% margin, and Adjusted Diluted EPS of $4.15.
Its preliminary 2027 outlook is gross profitgrowth of at least 15% and Adjusted Operating Income of $4.575 billion, up 30%. At its November 2025 Investor Day, Block had put 2027 Adjusted Operating Income at $3.510 billion, the letter’s table shows.
Against the Card on X
Wall St Engine, an account that posts earnings figures on X, put revenue at $6.72 billion against an estimate of $6.59 billion, and Adjusted Operating Income at $923 million against $855 million. It put Cash App inflows at $86.00 billion against an estimate of $89.47 billion, and cited a 2027 Adjusted Operating Income estimate of $4.25 billion.
Those reported figures match Block’s letter; we have not verified the estimates. The post did not show the personnel and software lines, or the DOJ accrual, which are in the 10-Q.
What the risk factors say
Block’s third-quarter 10-Q lists 51 risk-factor headings, by our count. Against its 10-K for 2025, filed on 26 February, two headings are new. One reads: “Our workforce reductions and reorganizations, including changes to our operating model and the potential for increased reliance on proactive intelligence and AI tools, may not achieve their intended benefits and could adversely affect our business, financial condition and results of operations”.
The other reads: “Our loan products expose us to increased credit losses and are subject to risks related to general macroeconomic conditions”.
The factor headed “The development and use of AI in our products and our internal operations may result in reputational and competitive harm and could adversely impact our business” grew to 516 words from 368 in the 10-K, by our count. Against the second-quarter 10-Q, filed on 5 August, no heading is new or changed, by our parse.
The largest named theme by share of words is legal, antitrust and tax, at 23.9%, by our classification.
How Each Side Reads These Figures
For readers who see strength, the figures include gross profit up 22%, Adjusted Operating Income up 92% at a 29% margin, Cash App gross profit up 27%, and a 2027 Adjusted Operating Income outlook of $4.575 billion.
For readers who see caution, the figures include GAAP operating income up 5%, a $764 million accrual for the DOJ matter, losses up 66%, Cash App inflows growth of 10%, and a new risk factor saying the workforce reductions may not achieve their intended benefits. We cite no analysts’ views here.
As we read it, the 10-Q shows part of the workforce saving reappearing as a software bill: the filing names AI-related tools and data centre fees among the reasons that line rose, though it does not split the two.
As we read it, Cash App’s gross profit grew faster than the money flowing in partly because Block earned more on each dollar of Commerce Enablement volume: inflows grew 10%, gross profit 27%, and the Commerce Enablement monetization rate rose 18 basis points.
As we read it, the adjusted and GAAP lines tell different stories this quarter: Adjusted Operating Income rose 92%, while GAAP operating income rose 5% as litigation and regulatory accruals rose by $421.1 million.

Three Implications
FOR INVESTORS TRACKING BLOCK Adjusted Operating Income was $923 million, up 92%, and the 2027 outlook is $4.575 billion; GAAP operating income was $428 million, up 5%, and the DOJ resolution is not final.
FOR FINANCE TEAMS WEIGHING AI AGAINST HEADCOUNT Block’s 10-Q shows personnel costs down $250.6 million across three lines and software and cloud fees up $93.8 million, by our arithmetic, after a workforce cut of more than 40%; it does not say how much of the fee increase is AI.
FOR SQUARE SELLERS AND CASH APP USERS Block says Squaremates is generally available in the U.S. and the Square Kiosk takes voice orders; Cash App reached 60 million monthly transacting actives in September.
The framework puts it this way: “As companies move from chatbots to thousands of autonomous agentic workflows running 24/7, the line item that used to be a rounding error becomes the budget.”
As we read it, Block’s 10-Q shows that line item at the scale of one company: software and cloud fees rose by $93.8 million in a quarter in which personnel costs fell by $250.6 million across three lines, by our arithmetic. The framework was published in June 2026 and does not discuss Block.
This piece is based on Block’s third-quarter 2026 shareholder letter, filed as Exhibit 99.1 to its 8-K of 3 November 2026, and its 10-Q for the same quarter. The $250.6 million net change, the 37-cent ratio and the 77% share are our arithmetic, not company statements.
The 10-Q does not say how much of the $93.8 million fee increase is for AI-related tools rather than other software or data centres, and personnel costs in cost of revenue are not itemised. It does not give a headcount. We did not hear Block’s earnings call, scheduled for 5:00 p.m. Eastern Time (22:00 UTC) on 3 November. We did not contact Block.

This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
After cutting its workforce by more than 40%, Block reported personnel costs $250.6 million lower across three expense lines and software and cloud fees $93.8 million higher, by our arithmetic from its 10-Q. Adjusted Operating Income rose 92%, to $923 million; GAAP operating income rose 5%, as accrued expenses for litigation and regulatory matters rose by $421.1 million.

A note on sourcing. Every company figure comes from Block’s third-quarter 2026 shareholder letter, filed with the SEC as Exhibit 99.1 to an 8-K, and its 10-Q for the quarter, both read on EDGAR on 3 and 4 November. Adjusted Operating Income, Adjusted EBITDA and Adjusted Diluted EPS are non-GAAP measures. The estimates are as posted by Wall St Engine on X and are not verified.
The net personnel change, the 37-cent ratio, the 77% share and the risk-factor counts are our arithmetic. We did not contact Block.
