V12: Revenue stability — how to analyze it

Stable revenue = predictable cash flows = the company can plan, invest, and grow without share issues. Volatile revenue = the company must hold extra cash = lower efficiency.

This is V12 — Revenue stability in the AKM1 model: one of the 20 variables that together determine whether a company is an institutional quality stock or a company of stories. In this article you get the variable explained, how to calculate it yourself, and how three of history's greatest investors would have interpreted it.

Why the variable exists

Cash flow stability as an analytical concept was developed late compared with other financial metrics. While the debt-to-equity ratio and liquidity were already being analyzed in the 1930s by Graham and Dodd, cash flow statement analysis only became mainstream in the 1980s. Two drivers: 1) Buffett and Munger popularized 'owner earnings' (cash flow minus capex) as the true value. 2) The scandals of the 2000s (Enron, Worldcom) showed that earnings could be manipulated through accounting, but cash flow was harder to fake. In the 1990s the SaaS business model (Salesforce 1999, Netflix 2007, Adobe 2013) became a new paradigm — 'ARR' as a metric was created. Pre-SaaS, 'recurring revenue' was mainly newspaper subscriptions, gym memberships, and service contracts.

Stability over time — the forgotten dimension

Three dimensions of stability The AKM1 stability category has three variables that answer different time horizons. Debt-to-equity ratio (V10) — long-term financial structure, a 5-10 year perspective. Liquidity (V11) — short-term survival, a 30-90 day perspective. Cash flow stability (V12) — medium-term predictability, a 1-3 year perspective. V12 answers the question: 'if you look at the company's cash flow from operations over the last 5 years — how stable is it?' A company that generates 100 MSEK in operating cash year after year (small variation) has high cash flow stability. A company whose operating cash swings between 50 MSEK and 200 MSEK has low. This stability is fundamental for investors: it determines the safety of the dividend, the ability to reinvest, and the company's capacity to carry debt across a business cycle. 📖 DEFINITION Cash flow stability = the degree of predictability in the company's operating cash flow over time. High = ARR-based or contract-based revenue.

Assessing cash flow stability in practice

Five-step process Step 1: Calculate the ARR share — read the CEO statement or the note on 'Revenue structure' or 'Recurring revenue'. Some companies (SaaS) report ARR directly. Others (industrial) require you to look for 'Service' or 'Aftermarket' as segments. Step 2: Assess contract lengths — read the notes to the accounts on 'Agreements' or 'Contracts'. Multi-year agreements (3-5 years+) give high stability. Monthly agreements give low. Step 3: Analyze customer lifetime — look for 'Average customer relationship' or 'Churn rate'. Companies with churn <5% have high stability; >15% have low. Step 4: Look at the historical variation of the cash flow — calculate the standard deviation of operating cash flow over 5 years. Low variation = high stability. Step 5: Assess cycle sensitivity — compare operating cash in an economic boom vs a recession. Non-cyclical companies (pharma, software) have high stability; cyclical ones (industrial, construction) have low.

Stability traps and illusions

The ARR illusion — high churn A company can have 'ARR 60%' but if churn is 30% per year, ARR is not stable — customers leave quickly and new ones must replace them. Effective 'renewed ARR' is much lower than reported ARR. Three problems: 1) 'Gross ARR' vs 'Net ARR' — a company can report 'ARR 100 MSEK' but if churn is 30 MSEK, the net is only 70 MSEK. 2) NRR (Net Revenue Retention) — if NRR <100%, the existing customer base shrinks. 3) Contract renewals — companies with 1-year agreements and 80% renewal have 'stability' but not as strong as 5-year agreements with 95% renewal. Read the notes to the accounts on 'Churn' or 'Retention' carefully. Salesforce (NRR 120%+) has genuine ARR stability. Sinch (historical NRR ~95%) had 'ARR' but not stable — crashed in 2022. Lesson: combine the ARR share with NRR and churn to judge true stability.

Three perspectives on revenue stability

Peter Lynch: Lynch loved companies with 'predictable earnings' — a stable revenue base. He argued that predictability is worth a premium. 'A company where you know what next quarter brings is worth more than one where you guess.' Lynch preferred consumer goods and pharmaceuticals (stable) over cyclicals (volatile).

Benjamin Graham: Graham emphasized revenue stability strongly. His 'defensive investor' rule: positive earnings every year for the last 10 years. Graham argued that stability indicates a durable business model. 'A company with loss years is a company you do not understand.' He adjusted the value downward for volatile companies.

AK1's interpretation: AKM1 weight 5%. Revenue stability is assessed on three axes: (1) annual variance — low variance = good, (2) ARR share — high ARR = stable, (3) cyclical exposure — cyclical companies (mines, banks) have naturally volatile revenue. AKM1 adjusts stability for cyclicality — a steel company with 30% revenue variance can be 'stable' in its context.

FAQ

What is revenue stability — and why does it matter?

Revenue stability is about how predictable a company's revenues and operating cash flow are over time. Stable revenues let the company plan, invest and grow without issuing new stocks, while volatile revenues require buffers and reduce efficiency. In fundamental analysis, stability is a measure of business-model quality — it determines the safety of dividends and the ability to carry debt through an economic cycle.

What is ARR and how does it differ from regular revenue?

ARR (Annual Recurring Revenue) is revenue that recurs automatically every year, usually through subscriptions or contracts — the model that made software companies like Salesforce and Adobe famous. Regular one-off revenue must be earned anew with every sale, while ARR accumulates. In the stability hierarchy, recurring revenue (ARR) ranks strongest, then contract revenue, and finally one-off sales. The higher the ARR share, the more predictable the cash flow becomes.

How do I assess whether revenues are genuinely stable?

Combine several metrics: the share of recurring revenue, contract lengths, churn (customer attrition) and NRR (net revenue retention). A high ARR share means little if churn is 30 percent — customers then leave as fast as they arrive. Read the notes to the accounts on revenue structure, retention and customer relationships in the annual report, and compare operating cash flow between economic boom and recession to gauge cyclicality. The course Revenue Stability (V12) practises the method step by step.

Are there companies where volatile revenues are still normal?

Yes — cyclical industries such as mining, steel and construction naturally swing with the economic cycle, and that is part of their business model. There the question becomes how the company handles the swings: does it keep debt low and build cash buffers in good years? The AKM1 model therefore adjusts the stability assessment for cyclicality — a steel company with 30 percent revenue variation can be stable in its context, while the same variation at a pharmaceutical company would be a warning sign.
