Alphabet's July–September 2026 results showed negative free cash flow (FCF) of $9.07 billion. Operating cash flow was $42.29 billion, but capital expenditures reached $51.36 billion, so spending outran cash generation. However, two items pushed operating cash flow down: payment of a European Commission (EC) fine and a buildup of inventory ahead of TPU system sales. Together they account for roughly $8.4 billion in cash outflows. Adding them back mechanically puts operating cash flow at about $50.7 billion, roughly in line with capex. Backing into the fourth quarter from the full-year capex plan, though, implies investment of about $63 billion to $73 billion. The author expects that the FCF deficit could grow beyond this quarter's $9.07 billion in Q4.
EPS fell mainly on equity losses, while operating income rose 30%
Alphabet's July–September revenue was $127.58 billion, up 25% year over year. Operating income rose 30% from $31.23 billion a year earlier to $40.58 billion, for an operating margin of 31.8%. Google Cloud was especially strong: revenue rose 103% year over year to $30.71 billion, and operating income more than tripled from $3.59 billion to $11.12 billion. Its operating margin rose from 23.7% to 36.2%. Cloud revenue includes sales of TPU systems, which the company cited as one factor behind the sharp revenue growth.
In contrast to this operating strength, diluted earnings per share (EPS) fell from $2.87 a year earlier to $2.12. The main cause was a deterioration in non-operating items, which swung from a $12.76 billion gain a year earlier to an $8.22 billion loss this quarter. Gains and losses on equity holdings were the largest swing, moving from a $10.73 billion gain to an $8.66 billion loss. In its earnings release, Alphabet said this loss reduced EPS by $0.55. On the earnings call, CFO Anat Ashkenazi said the main factor was an unrealized loss from the decline in the value of its SpaceX shares.
Importantly, this valuation loss involves no direct cash outflow. In fact, the cash flow statement adds back a $9.05 billion loss on marketable securities when calculating operating cash flow. In other words, the EPS decline reflects mainly an accounting effect from valuation losses on holdings, not a weakening of the core business. Meanwhile, a separate issue has emerged in actual cash flows, and it shows up in the sizable FCF deficit.
Breaking down the $9.07 billion FCF deficit
FCF is operating cash flow minus capital expenditures. Operating cash flow this quarter was $42.29 billion, down $6.12 billion from $48.41 billion a year earlier. Capex, meanwhile, expanded about 2.1 times from $23.95 billion to $51.36 billion. As a result, FCF swung from a $24.46 billion surplus a year earlier to a $9.07 billion deficit. Of the $33.53 billion year-over-year change, about $27.4 billion came from higher capex, making the rapid expansion of investment the largest factor behind the swing into deficit.
Operating cash flow was also depressed by one-time outflows. According to CFO Ashkenazi, one was payment of a fine imposed by the European Commission in 2018. The payment, made after the appeals process concluded, was about $5.2 billion. The other was the inventory buildup to prepare for expanded TPU system sales. The cash flow statement shows the cash outflow from higher inventory growing from $0.53 billion a year earlier to $3.22 billion, and balance-sheet inventory rose from $2.44 billion at the end of December 2025 to $13.31 billion at the end of September 2026.
Adding back the roughly $5.2 billion fine and the $3.22 billion inventory increase gives operating cash flow of about $50.7 billion. The gap to capex of $51.36 billion is about $0.6 billion, which means FCF would have been roughly break-even this quarter without those two items. However, the fine amount is an approximate figure given on the earnings call, and the inventory increase reflects changes in total inventory, not just TPU-related stock. The amount for TPU system inventory alone has not been disclosed, so this calculation is meant to help sort out the causes of the FCF deficit, not to indicate sustained cash-generating power.
In fact, there were also working capital deteriorations that this calculation does not adjust for. In the same quarter, an increase in other assets reduced cash by $7.81 billion, up sharply from $0.77 billion a year earlier. Higher accounts receivable reduced cash by $3.92 billion, and the net effect of income taxes reduced cash by $3.70 billion. The calculation that, excluding the fine and inventory increase, operating cash flow roughly matches capex therefore does not mean Alphabet's operating cash flow has structurally reached a level that can fund capex.
Looking at the FCF trend, the deterioration did not begin suddenly this quarter. FCF was a $10.12 billion surplus in the first quarter of 2026, turned into a $5.86 billion deficit in the second quarter, and the deficit widened to $9.07 billion in the third. Because the fine was a one-off payment this quarter, the second-quarter deficit cannot be explained by the same reason. Cash outflows from inventory increases totaled $10.96 billion over nine months, of which about $7.74 billion occurred in the first and second quarters. Even so, FCF over the last twelve months remains positive at $19.75 billion.
This early inventory buildup is tied to how TPU systems are sold. A TPU system combines AI chips designed by Google with networking and software; after a contract is signed with a customer, components are procured, the system is built and delivered, and payment is then collected. Google Cloud CEO Thomas Kurian explained that all inventory secured for TPU systems is tied to contracted deals. In other words, cash is going out ahead of revenue recognition and payment collection to prepare products that correspond to future sales. At ¥157 to the dollar, this quarter's FCF deficit is equivalent to about ¥1.42 trillion, and capex to about ¥8.06 trillion.
Swelling Q4 capex, and the conditions under which this view breaks down
Alphabet has guided to full-year 2026 capex of $195 billion to $205 billion, and CFO Ashkenazi said on this earnings call that the plan was unchanged. Nine-month capex totals $131.95 billion, so if the plan holds, Q4 alone would see about $63 billion to $73 billion invested. Using the roughly $50.7 billion in operating cash flow this quarter, after adding back the fine and the inventory increase, as a baseline, the Q4 cash shortfall would be about $12.3 billion to $22.3 billion. This is an estimate that assumes operating cash flow stays at the same level, not a company FCF forecast.
That said, operating cash flow could rise in Q4. Last year's fourth quarter was $52.40 billion, about $4 billion above the third quarter's $48.41 billion. If a similar increase occurs this time, the cash shortfall would narrow to about $8.3 billion to $18.3 billion. If capex comes in near the low end of the plan, the FCF deficit could be smaller than this quarter's $9.07 billion. The view that the deficit will widen beyond this quarter therefore holds only if capex lands between the midpoint and upper end of the plan and operating cash flow improvement fails to keep pace.
The main counterargument to this view is that the current FCF deficit is merely temporary. Because inventory for TPU systems corresponds to contracted deals, cash that went out early should return as deliveries and payment collection proceed. Google Cloud's backlog has reached $561 billion, and the company expects to recognize more than 55% of it as revenue over the next 24 months. In addition, Alphabet holds $265.1 billion in cash and marketable securities, giving it the financial capacity to fund near-term investment.
Still, the author expects the deficit to widen in Q4 because of the timing gap between expanding TPU system sales and rising capex. Ashkenazi said TPU system revenue will grow in Q4 too, but that the real step-up in earnings will come in 2027. She also indicated that infrastructure investment and the TPU inventory buildup will continue to weigh on FCF. If the real expansion of sales comes in 2027, cash collection may not progress enough in Q4 to offset the inventory buildup. In addition, use of external compute resources is expected to rise in Q4, putting downward pressure on cloud margins.
At the same time, funding is not a problem right now. Debt financing of $29.0 billion this quarter plus $12.4 billion in proceeds from stock issuance totals about $41.4 billion, roughly 4.6 times the $9.07 billion FCF deficit. Share repurchases, which were $11.5 billion a year earlier, were zero this quarter. Long-term debt rose from $46.55 billion at the end of December 2025 to $125.10 billion at the end of September 2026, but cash and marketable securities also built up, from $126.84 billion to $265.10 billion. Alphabet is pressing ahead with massive infrastructure investment while increasing both debt and cash on hand.
The focus is not whether investment funds are sufficient, but when operating cash flow will catch up with capex. Alphabet has indicated that 2027 capex will increase substantially further, and future purchase commitments reach as much as $924 billion. However, because these contracts leave room to change prices and volumes, not all of it will necessarily become cash outlays. Either way, which moves faster, cash collection from expanding TPU system sales or new investment in AI infrastructure, will determine future FCF.
Whether this view is right can be tested in the Q4 results. If the FCF deficit stays at or below this quarter's $9.07 billion, operating cash flow will have improved more than expected relative to higher capex, and the author's forecast will have been wrong. It is possible that payment collection on TPU inventory proceeded faster, but judging that would require checking changes in working capital such as inventory and accounts receivable. Conversely, if the deficit widens beyond $9.07 billion, this quarter's deficit will have been one stage in a process of continuing, larger cash outflows.
Alphabet's operating income is growing strongly, and it has the financial capacity to keep making massive investments in AI infrastructure. But growth in profit is not the same as generating cash. With capex rising further in Q4, how far cash collection from TPU system sales progresses will be a key clue for judging whether the company's cash generation can support the investment expansion in 2027 and beyond.
