The AI arms race costs money
And rising corporate bankruptcies
Mag 7 Capex
Accounting is boring but important. Particularly important: the difference between a capital expense and an operating expense. A capital expense (buying a big piece of equipment, say) does not count directly against earnings on the income statement, as an operating expense (paying a salary, say) does. Instead, a capital expense appears on the income statement over time, in theory matching the drag on profits to the life of the capital asset. This spread-out expense shows up in a line called “depreciation”.
I see you sleeping at the back. But I drag you through this tiresome point because the most important companies in the world, the Magnificent 7 Big Techs, are running up a huge amount of capital expenditure, mostly on data centres for artificial intelligence. This is cash out the door today, but the expense will only appear in earnings per share over time. The AI arms race has not fully hit profits yet. The question is whether the market has digested the fact that it must do so before long.
Here is capex at the five of the seven that are, to greater or lesser extents, going bananas on capex (at Apple, capex is steady; at Nvidia, the capex money is coming in, not going out):
These are staggering numbers, and they are still growing.
Amazon looks like an outlier, but that is not quite true. One needs to scale the spending to the rest of the company’s financials. For example, one can look at capex as a percentage of revenue:
At Meta and Microsoft, one of every five dollars that comes in the door goes out as capex; at Alphabet, it is one in seven. And the trend is up (wondering about that big mountain of spending in 2022 at Meta? Remember the Metaverse?).
Now we have a sense of the scale of the spending. But what is important for our topic is the scale of the capital spending compared to what is currently being charged against profits. That is, what is capex relative to depreciation expense? As of the past 12 months, here is what that looks like:
Take Meta for example: depreciation expense is 9 per cent of revenue, capex 20 per cent. That means depreciation expense has to go up significantly in the coming years. That does not mean the group’s operating margins have to eventually fall by the difference (11 per cent); data centre capital expenditures will be spread over four to five years. But if the current level of spending keeps up, the drag on margins will be significant.
So, how much margin compression do Wall Street analysts’ estimates price in for these five companies in the next few years, as AI capex comes home to roost? None whatsoever. At all five companies, in fact, operating margins are expected to expand a bit in the next few years. This is possible, of course. Except for Tesla, all of these companies are increasing revenues quickly, and there is plenty of operating leverage in their models. But it won’t be easy. The optimism about Big Tech profits momentum overcomes all.
