Alphabet and Meta sell the same thing — attention, priced by auction — and both are currently spending their cash flow on the same bet. Investily scores Meta 86 and Alphabet 79. On trailing earnings Alphabet looks substantially cheaper. On next year's numbers that gap almost entirely disappears, and why it disappears is the whole comparison.
Both are spending their cash flow
Start with what they have in common, because it is unusual. Free cash flow fell at both companies over the trailing year — Alphabet down 19.7%, Meta down 17.5%. Two of the most profitable businesses ever built are producing less spare cash than they did a year ago, at the same time, for the same reason.
The capital is going into AI infrastructure, and you can see it land on the balance sheet. Alphabet's book value grew 74.9% over the trailing year against revenue growth of 20.8%. Meta's grew 34.1% against revenue growth of 28.9%. Both are building faster than they are selling; Alphabet is doing it far more aggressively.
Growth and margin: Meta wins both
- Revenue growth, trailing year — Meta 28.9%, Alphabet 20.8%
- Net margin — Meta 40.0%, Alphabet 31.1%
- Return on capital — Meta 30.6%, Alphabet 29.3%
- Operating income growth — Alphabet 22.4%, Meta 11.5%
Meta grows faster and keeps more of it, and their returns on capital are close enough to call a tie. The one line Alphabet wins is operating income growth, and that is worth reading carefully rather than as a point on the scoreboard — Meta's operating income grew 45.9% a year over three years, so an 11.5% trailing figure is a slowdown from an exceptional base, not weakness.
The valuation gap that isn't
On trailing earnings Alphabet trades at a meaningful discount to Meta — roughly a quarter cheaper. That is the number most comparisons stop at, and it is the most misleading figure on either report card.
On next year's consensus the two multiples are, for practical purposes, identical. The trailing discount evaporates because of what analysts expect each company to earn: Meta's earnings per share are forecast to grow 20.7%, Alphabet's 1.6%. Alphabet is not cheaper. It is priced for a year in which its earnings barely move.
What each one is actually asking you to believe
These are two different bets wearing similar multiples. Alphabet asks you to believe that a 75% expansion of its capital base produces returns before the market loses patience, and that search economics survive the thing it is spending the money on. Its balance sheet gives it room to be wrong — debt to equity of 0.1 is close to unlevered.
Meta asks you to believe the 20.7% earnings growth in the consensus actually arrives. It has the better margin, marginally better returns, faster growth, and a shorter track record of capital discipline. Its score of 86 reflects the first three; the risk sits in the fourth.
The bottom line
The seven-point score gap comes almost entirely from growth and margin, not from valuation or balance sheet, and on the forward numbers the market has already closed the pricing gap between them. Anyone buying Alphabet as the cheap one should know they are buying a trailing discount that consensus does not expect to persist.
The more interesting question is the one they share. Both are converting cash flow into capital at a rate their revenue growth does not yet justify, which is the same pattern we found at Microsoft. Whether that is vision or overreach will not be settled by this year's numbers.
