The Most Efficient Ad Company on Earth

All figures in US dollars. Meta reports in USD; the tear sheet displays earnings per share in cents (2,349 = $23.49 per share).

Meta Platforms operates the world's largest family of social media and messaging applications — Facebook, Instagram, WhatsApp, Messenger, and Threads — reaching approximately 3.56 billion daily active people across the family of apps. The overwhelming majority of revenue comes from digital advertising: businesses pay to place targeted ads in front of Meta's enormous user base.

The company reports in two segments: Family of Apps (the advertising business, which generates essentially all the profit) and Reality Labs (the metaverse and augmented/virtual reality hardware division, which continues to lose money heavily). The investment case rests almost entirely on the advertising business and, increasingly, on how artificial intelligence is improving its efficiency.

It's interesting — I had not realised quite how much Meta has grown in terms of both revenue and profit over recent years. FY 2024 to FY 2025 wasn't a great profit growth year (post-tax profit actually declined from $62.4 billion to $60.5 billion), but if we compare FY 2025 back to FY 2020, post-tax profits have grown by 107% — nearly 22% per year on average over that five-year period. While FY 2025 saw earnings per share decline by 1.6%, over two years earnings per share has grown 25.7%, and over three years 39.8%. They have been growing at quite a rate.

Six-year financial history ($bn unless stated)

The net borrowing trajectory is worth flagging: Meta has gone from a net cash position of $6.9 billion in FY 2020 to net debt of $48.0 billion in FY 2025, driven by the colossal capital expenditure programme. Total debt at Q1 2026 was $58.7 billion.

Q1 2026 results

Revenue of $56.3 billion was up 33% year-on-year — the fastest quarterly growth since 2021. Ad revenue of $55.0 billion drove the result, with impressions up 19% and average price per ad up 12%, showing both higher usage and better monetisation.

However, the headline earnings per share of $10.44 is misleading: it includes an $8.03 billion discrete tax benefit relating to Corporate Alternative Minimum Tax relief. Stripping that out, underlying earnings per share was approximately $7.31 — still 10% better than the $6.66 consensus. Operating margin held flat at 41% despite costs rising 35%.

Forward guidance

The capital expenditure raise to $125–145 billion was significant — shares fell 6–7% after hours on this announcement. At the midpoint of $135 billion, Meta's annual capital spending exceeds the GDP of over 120 countries.

The capex programme is overwhelmingly directed at artificial intelligence infrastructure:

Capital expenditure breakdown

In FY 2025, capex was $72.2 billion — up roughly $30 billion from the year before. The FY 2026 midpoint of $135 billion represents an 87% increase on that. Meta has established a new division called "Meta Compute" to manage its AI data centre ambitions.

Artificial intelligence is now central to Meta's monetisation strategy and has materially impacted the business across several dimensions:

AI impact across the business

As one industry analyst put it, Meta's true transformation has been into the most efficient ad company on earth. WARC forecasts Meta ad revenue of $240 billion in 2026, up 22.3%.

My general inclination is that the company can continue with an earnings per share growth rate of about 20% over the medium term. That might seem a lot, but I believe they are just at the beginning of their AI cycle — there will be much more improvement to their metrics as a result of advances in AI. What I actually expect is more volatile figures than that — sudden jumps in profitability rather than smooth compounding. They have been cutting staff numbers and implementing AI at a heavy rate. Their AI expenditure has been, and will continue to be, colossal for this and coming years.

The capital expenditure level is pretty mind-blowing — $125–145 billion for a single year.

For someone like me on the outside, I look at Meta and ask: what's new in the last few years? I'm not really aware of anything fundamentally transformative. But clearly the revenue and profit growth tells a different story — they are extracting ever more value from their existing user base through AI-driven ad efficiency.

At a 20% growth rate and a 9x multiple, the stock screens as approximately fair value — a −1.8% value opportunity. The 35% risk factor reflects the massive capex commitments, the uncertain return profile on AI infrastructure investment, and the general macro environment.

VALUATION SNAPSHOT

The shares fell 6–7% on the capex raise despite beating on revenue and earnings, which tells you the market's concern: the spend is accelerating faster than confidence in the payoff.

• Capex return profile: $125–145 billion of annual capital spending is an enormous bet on AI infrastructure. If the returns don't materialise, this destroys shareholder value on a colossal scale. The market's 6–7% selloff on the capex raise reflects this concern.
• Net debt swing: Meta has gone from $6.9 billion net cash to $48 billion net debt in five years. The capex programme is now being partly debt-funded, increasing financial risk.
• Reality Labs losses: The metaverse division continues to lose money heavily, a persistent drag that the advertising business has to carry.
• Regulatory risk: Meta faces ongoing antitrust scrutiny in the US and EU, plus data privacy regulation that could constrain its ad targeting capabilities.
• Single revenue stream: The business is almost entirely dependent on advertising. Any structural shift in digital advertising — or a recession that cuts ad budgets — hits Meta directly.
• "What's actually new?": The growth is coming from squeezing more value from the existing user base rather than genuinely new products. That can continue for a while, but it isn't infinite.

• Share price below $500: Would open up a clear value opportunity and provide a margin of safety against the capex risk.
• Evidence of capex payoff: Clear demonstration that the AI infrastructure spend is driving incremental revenue and margin — not just cost — would justify a higher multiple.
• Sustained 20%+ earnings growth: If Meta delivers the medium-term growth I expect, the current price would prove cheap in hindsight.
• Capex discipline: Any signal that the company is moderating the capex trajectory toward returns rather than raw scale would reduce the risk factor.
• Reality Labs narrowing losses: A path to breakeven for the metaverse division would remove a persistent drag and improve group economics.
