Capex/FCF -> Debt/Leverage
Most ROI analysis on AI has focused on Big Tech capex and FCF.
But as more companies approach zero or negative FCF, I think the focus needs to shift toward net debt and leverage.
Given the ROI we are seeing from AI investments, I suspect companies will not pause spending simply because FCF hits zero - which is already happening for some names. The real constraint is more likely to come when companies (first) move into net debt, and (then) when leverage reaches a level that is no longer sustainable.
The complication is that many Big Tech companies now have meaningful off-balance-sheet obligations - finance leases, operating leases, JVs, purchase commitments, and cloud/infrastructure commitments. These may not show up as debt today, but they will likely become a drag on FCF over time.
-------------------
$GOOGL
$GOOGL is relatively clean from an off-balance-sheet perspective, other than approximately $76B of leases not yet commenced.
Management has also said
$Googl does not intend to move into a net debt position. Using consensus estimates from Visible Alpha and assuming
$Google is willing to run down to roughly zero net cash, the implied maximum capex for FY27 would be approximately $280B, or roughly 50% YoY growth.
$GOOGL also has some buffers:
- ~$40B from the $80B equity raise (a $15B convert, $15B common equity, $10B private placement, and $40B ATM offering) (source:
reuters.com/legal/transactio…)
- ~$10B per year of dividends that could theoretically be adjusted.
-------------------
$META
$META has much larger off-balance-sheet commitments.
The two biggest buckets are:
1. Leases not yet commenced - $183B off balance sheet as of 1Q26
2. Non-cancelable contractual commitments - $238B as of 1Q26
Importantly, $42.25B is due in 2026 and $47.65B is due in 2027.
$Meta also disclosed several additional items that are worth tracking separately:
- A contingent obligation to purchase up to $14.72B of cloud capacity over five years
- April 2026 infrastructure contracts that increased non-cancelable commitments by another ~$24B
- Unconsolidated VIE exposure of $46.0B maximum exposure to loss tied to venture economics
It is impossible to know the exact future FCF, cash, and debt impact from these off-balance-sheet items. But directionally,
$Meta looks much more likely to move into a net debt position once we account for these obligations - especially given the $42.25B due in 2026 and $47.65B due in 2027.
-------------------
Bottom line
The AI capex debate should not stop at reported capex and FCF. For companies with large off-balance-sheet commitments, the better question is: what does the balance sheet look like once these obligations start flowing through cash? On that basis:
$GOOGL still looks relatively clean and has the most balance-sheet flexibility.
$META has the most meaningful off-balance-sheet risk and is likely to move into a net debt position.
$AMZN has large commitments and seems certain to move into net debt.
Net-net, I actually (weirdly) feel better after going through this exercise.
1/ These companies still have some cash buffers. Even after adjusting for off-balance-sheet commitments, most are not getting to an unsustainable leverage position in the near term.
2/ This analysis is based on consensus cash flow from operations. Actual CFO could come in higher if AI ROI starts showing up more meaningfully.
3/ Companies still have some flexibility - not a ton, but some - if they decide to slow or pause share repurchases and dividends.
So the conclusion is not that Big Tech is immediately constrained. The better question is: how far can they push AI infrastructure spending before the balance sheet, not the income statement, becomes the constraint?
