A segment is a piece of a company that management runs and measures separately. Companies with more than one have to report each of them in a note to the financial statements.
A segment is a piece of a company that management runs and measures separately. Companies with more than one have to report each of them in a note to the financial statements.
That note is the most useful page in many 10-Ks. A single company-wide profit figure hides everything. Segment reporting shows you which part earns the money and which part spends it.
Two figures per segment matter. Revenue tells you the size. Operating income tells you whether it pays.
Alphabet for the year that ended December 31 2023.
| Segment | Revenue ($M) | Operating income ($M) |
|---|---|---|
| Google Services | 272,543 | 95,858 |
| Google Cloud | 33,088 | 1,716 |
| Other Bets | 1,527 | (4,095) |
| Alphabet-level activities | — | (9,186) |
| Hedging gains | 236 | — |
| Total | 307,394 | 84,293 |
Read the revenue column first. Google Services is 89% of revenue. Cloud is 11%. Other Bets is half of one percent. Whatever the headlines are about, this company sells advertising and services.
Now read the profit column, which tells a different story. Cloud turned $33,088 million of revenue into $1,716 million of operating income. That's about a 5% operating margin, against roughly 35% for Services. Cloud is large and barely profitable.
Other Bets lost $4,095 million on $1,527 million of revenue. It spent almost $3.70 for every dollar it took in. Alphabet-level activities cost another $9,186 million and belong to no segment at all.
Put it together. Google Services earned $95,858 million and the rest of the company gave back $11,565 million of it. That's a cross-subsidy, and the segment note is the only place you can see it.
Note the small line too. Hedging gains of $236 million sit in revenue and belong to no segment. 272,543 plus 33,088 plus 1,527 plus 236 is 307,394. The pieces only add up when you include it.
The trap is assuming segments add to the whole.
They usually don't, and the gap is not an error. Companies hold costs at the corporate level that they don't push down into any segment. Alphabet calls it Alphabet-level activities and it's $9,186 million. There are reconciling lines in revenue too, like the hedging gains.
So add the segments and compare with the total every time. Whatever's left over is a real cost that somebody pays, and it is usually the cost of being one company rather than several.
The second trap is judging a segment by revenue alone. Cloud is the second biggest line by revenue and one of the smallest by profit. Revenue tells you scale. Only the profit column tells you whether the scale is worth having.
Your manager says Alphabet should sell Other Bets because it loses money.
State what Other Bets did.
Revenue of $1,527 million and an operating loss of $4,095 million.
How much does it lose per dollar of revenue?
$4,095 million divided by $1,527 million is about $2.68 of loss for each dollar of revenue. It spends about $3.68 to take in $1.00.
How big is that loss against the company's operating income?
$4,095 million against $84,293 million is about 4.9%.
Give your manager the honest read.
Other Bets costs about 5% of operating income and is funded by Google Services. Whether that's worth it is a judgement about what those bets might become. The segment note gives you the price of the decision and not the decision.
