Airbnb (ABNB) 2025 — 83% Gross Margin, Zero Goodwill, Growth Decelerating

Grade: B — Generally Healthy, Minor Concerns

Framework: Schilit *Financial Shenanigans* + Beneish M-Score + forensic accounting principles

Data: SEC EDGAR 10-K (Filed 2026-02-12) + Yahoo Finance

Auditor: PricewaterhouseCoopers LLP — Clean opinion (PCAOB ID 238)

One-line verdict: Airbnb runs one of the simplest, cleanest businesses in tech. $91.3B in bookings flow through the platform. Airbnb takes 13.4%. That produces $12.2B in revenue at 83% gross margin, $2.5B in net income, and $4.6B in free cash flow — on just $33M in capex. Zero meaningful goodwill. Zero long-term debt (the $2.0B convertible matures March 2026 and is fully covered by $11B in cash). Zero red flags on the 18-point screening. The concern is strategic, not accounting: revenue grew 10% but operating income was flat at $2.5B, expenses grew 13% (faster than revenue), and North America — 42% of total revenue — grew just 4%. For a company valued as a growth platform, the growth is fading while costs are accelerating.

The Toll Booth Model

*FY2023 net income of $4.8B includes a large deferred tax asset release. Underlying earnings were lower.

The business model is a toll booth. The 10-K states Airbnb has "grown into a global community of over 5 million hosts who have welcomed over 2.5 billion guest arrivals in almost every country and region across the globe." 533 million nights booked globally. Average daily rate up 3%, "primarily due to higher ADR in EMEA, which increased by 8%." Airbnb doesn't own a single property, employ a single housekeeper, or maintain a single building. Five million hosts do all of that. Airbnb collects 13.4 cents on every dollar.

83% gross margin, three years running. The 10-K explains that cost of revenue "includes payment processing costs, including merchant fees and chargebacks, costs associated with third-party data centers used to host our platform, and amortization of internally developed software and acquired technology." These costs scale linearly with volume — there's no COGS pressure, no commodity input risk, no supply chain.

But look at operating income: $2.5B in 2025 versus $2.6B in 2024. Revenue grew 10% and profit shrank. The 10-K income statement shows why: sales and marketing jumped 21% to $2.6B, product development rose 14% to $2.4B, and general and administrative costs grew 13% to $1.3B. Total costs and expenses grew 13% versus revenue growth of 10%. Airbnb is spending more to maintain growth, not less. That's the early signal of a maturing platform.

Cash Flow: The Purest Conversion

The 10-K's FCF reconciliation shows $33M in "purchases of property and equipment" — a rounding error for a $12B revenue company. Airbnb rents from cloud providers, sub-leases office space, and doesn't need inventory. Every dollar earned is essentially a dollar available.

FCF of $4.6B means 99.3% of operating cash flow converts to free cash flow. As the 10-K notes: "Our FCF is impacted by the timing of GBV because we collect our service fees at the time of booking, which is generally before a stay, experience, or service occurs." The company collects cash before hosts provide the service — the ultimate working capital advantage.

CFFO/NI ratio of 1.85x is excellent. CFFO significantly exceeds net income because non-cash stock-based compensation ($1.6B) flows through the income statement but not the cash flow statement.

Balance Sheet: Near-Zero Leverage

*The $2.0B in 0% convertible senior notes was reclassified to current liabilities as it matures March 15, 2026. The 10-K discloses: "As of December 31, 2025, we had outstanding $2.0 billion in aggregate principal amount of indebtedness of our 0% convertible senior notes due on March 15, 2026." The company has $11B in cash to cover it. After payoff, Airbnb will be entirely debt-free.

Goodwill of $754M is negligible — 9% of equity, well below the 50% threshold. Airbnb has never made a significant acquisition. The screening engine confirms: "Goodwill+Intangibles $0.8B = 9% of equity. Manageable."

The largest liability is approximately $7.0B in funds held for bookings in advance of check-ins. The 10-K explains: cash and short-term investments "do not include funds of $7.0 billion as of December 31, 2025, that were held for bookings in advance of guests completing check-ins, which are recorded separately on our consolidated balance sheets." This is float, not debt. It's interest-free financing that grows with the platform.

The Buyback Machine

The 10-K states: "In 2025, we repurchased 29.7 million shares of Class A common stock for $3.8 billion, leaving $5.6 billion available to repurchase under our share repurchase program." In August 2025, the board approved an additional $6.0B authorization. At the current pace, Airbnb is retiring about 4-5% of its float per year.

For a company without meaningful reinvestment needs (because capex is $33M), returning cash through buybacks is the rational capital allocation.

Watch Item #1: Growth Deceleration by Region

The 10-K breaks down revenue by geography:

North America grew 4%. Nights booked in North America grew just 3%. The 10-K shows "no single city represented more than 2% of our revenue" — the platform is remarkably diversified — but the aggregate slowdown in the company's largest market signals maturation.

Latin America (+20%) and Asia Pacific (+17%) are the growth engines. EMEA (+14%) is material and growing. International revenue hit 58% of total, up from 55% in FY2024.

The screening engine flagged this pattern: "Revenue grew 10.3% but CFFO only 2.8%." Revenue is growing faster than cash flow generation, which bears monitoring.

Watch Item #2: City Regulation Risk

The 10-K Risk Factors section warns explicitly: Airbnb is "subject to a wide variety of laws, regulations, and rules applicable to short-term rental, experiences, services, long-term rental, and home sharing businesses." The risk factor summary states: "If we are unable to successfully expand our global network or manage the risks presented by our business model internationally, our business, results of operations, and financial condition would be materially adversely affected."

New York City's 2023 regulations amount to a de facto ban on short-term rentals. Barcelona is phasing out tourist apartment licenses. Paris caps rental days at 120 per year. The 10-K adds: "Host, guest, or third-party actions that are criminal, violent, inappropriate, dangerous, or fraudulent may undermine the trust and safety or the perception of safety and security on our platform."

No single city accounts for more than 2% of revenue or 1% of listings — the risk is diversified. But the regulatory trend is directional: cities with housing shortages are increasingly hostile to short-term rentals.

$1.6B in Stock-Based Compensation

The 10-K's Adjusted EBITDA reconciliation breaks it down:

SBC of $1.6B is 13% of revenue — the primary difference between GAAP net income ($2.5B) and Adjusted EBITDA ($4.3B). When someone quotes Airbnb's "35% EBITDA margin," remember $1.6B in employee compensation has been excluded. GAAP operating margin of 21% is the real operating margin.

Auditor's Critical Audit Matter: Uncertain Tax Positions

PricewaterhouseCoopers identified one Critical Audit Matter: uncertain tax positions. The 10-K discloses "gross unrecognized tax benefits of $835 million relating to uncertain tax positions as of December 31, 2025."

The auditor explains: management's evaluation involves "a high degree of estimation uncertainty relative to the technical merits and the measurement of the tax positions based on interpretations of tax laws and legal rulings." PwC had to bring in "professionals with specialized skill and knowledge" to evaluate these positions.

This matters because Airbnb operates in 220+ countries with complex tax arrangements. The $835M in unrecognized tax benefits could swing either way — tax authorities could demand more, or disputes could be resolved favorably. It's the single largest area of judgment in Airbnb's financial statements.

Beneish M-Score

M-Score components: DSRI 1.148 (DSO growth slightly elevated), GMI 1.002, AQI 0.853, SGI 1.103, DEPI 1.000, SGAI 1.069, TATA -0.096, LVGI 1.060. All within normal ranges. No component is flagging.

Additional Scores: F-Score probability of misstatement 0.16% (very low). Altman Z-Score 2.10 (grey zone, driven by negative retained earnings from pre-IPO losses, not indicative of distress for a company with $11B cash and $4.6B FCF).

Key Risks from the 10-K

1. Competition — The 10-K's Risk Factor summary states: "The business and industry in which we participate are highly competitive, and we may be unable to compete successfully with our current or future competitors." Booking Holdings is Airbnb's primary competitor, with deeper hotel inventory.

2. Convertible Debt Maturity — $2.0B in 0% convertible notes matures March 15, 2026. The 10-K discloses capped call transactions at $360.80/share, "which represented a premium of 100% over the last reported sale price of the Class A common stock of $180.40 per share on March 3, 2021." The debt is fully covered by cash.

3. Host Supply and AI Risk — The 10-K notes: "In 2025, we introduced new artificial intelligence (AI) features to help deliver customer support" and warns that "AI presents risks and challenges that could affect the expansion of these features." The Co-Host Network (launched May 2025) aims to lower listing barriers.

4. Cloud Commitment — "We have a commercial agreement with a data hosting services provider to spend or incur an aggregate of at least $1.7 billion for vendor services through 2031." This is an off-balance-sheet obligation worth tracking.

5. Macro Sensitivity — The 10-K acknowledges: "we recognize the potential impact of challenging macroeconomic and geopolitical conditions on our business, including inflation, interest rates, foreign currency fluctuations, tariffs and trade controls, and potential decreased consumer spending."

Summary

Grade: B. Not eliminated. One of the cleanest financial statements in our screening universe.

83% gross margin. $4.6B FCF. $33M capex. Zero meaningful goodwill. Zero long-term debt post-March 2026. $9.0B net cash. No acquisitions, no complex financial engineering, no leverage. The toll booth collects 13.4% on $91.3B of bookings and converts almost all of it to free cash flow. Beneish M-Score of -2.79 is well in the safe zone. PwC gave a clean opinion with no material weaknesses.

The concern is not the financials — it's the growth trajectory. Revenue +10%. North America +4%. Operating profit flat. Expenses growing 13% versus revenue growth of 10%. SBC at 13% of revenue. These are the characteristics of a platform entering maturity, not one accelerating.

Two items flagged on the screening: AR growth (26.5%) outpacing revenue growth (10.3%), and CFFO growth (2.8%) lagging revenue growth (10.3%). Neither is alarming in isolation — AR is seasonal for a travel company, and CFFO is affected by timing of bookings versus check-ins — but together they suggest the cash conversion efficiency is plateauing even as the company spends more aggressively on growth.
