Pricing Power

What it is, what it costs to use, and why the numbers look their best while it is being spent.


Pricing power is the ability to raise a price without losing the customer. Few things show more clearly that a business has a moat, because a business without one cannot do it for long.

It can also be used up. Each increase turns part of the advantage into profit, and that part does not come back.

1 · Why raising a price is different from every other way to make money

Most ways to grow a business require selling more. More volume usually means winning customers from a competitor or finding new ones, which takes selling, time, and often a lower price to compete. Raising the price, however, needs no new customers. It only requires that the customers you already have cannot or will not easily leave.

Where the extra unit costs almost nothing to produce, as with software, data, or a required standard, nearly all of any increase reaches profit, and the temptation is strongest.

Management has to balance using this pricing power, which rewards shareholders, with keeping it. If prices rise too fast or too far and draw attention to the position, customers, regulators, suppliers, or competitors start to push against it. If pricing power is never used, investors may push for new management.

2 · Earned advantages and granted ones

EarnedGranted
Where it comes fromScale, switching costs, a network, a brand customers choseA rule, a mandate, or a standard that requires the product
How a competitor beats itBy building something better, which takes years and usually failsBy persuading whoever made the rule to change it
How it usually endsSlowlyOn a specific day, by decision

A granted advantage can look stronger than an earned one for years, because it produces the same high returns without the business having to keep earning them. It also depends on someone else continuing to agree, which an earned advantage does not.

3 · The years the numbers look best

Picture a business whose product is required at a checkpoint everyone has to pass. It raises the price many times over in a few years while the product stays about the same. Almost all of each increase lands in operating income. Margins rise, returns on capital rise, and earnings per share rise faster still because the extra cash buys back stock.

Reported results rise while the advantage is used up

Each price increase lifts the numbers investors watch. The same increases use up the advantage that allowed them, and nothing in the financial statements records it.

Reported results rising while the underlying advantage declines, across the same series of price increasesTwo panels share one horizontal axis, a series of price increases. In the top panel a solid gold line, labeled what the financial statements show, rises steadily as margins, returns on capital, and earnings per share improve. In the bottom panel a dashed navy line, labeled what is left of the advantage, starts high and slopes steadily downward across the same increases. A vertical dashed line runs through both panels near the right edge, marking the point where someone changes the rule, and nothing is drawn beyond it. There are no amounts, rates, dates, or results anywhere in the figure.WHAT THE FINANCIAL STATEMENTS SHOWmargins, returns on capital, earnings per shareWHAT IS LEFT OF THE ADVANTAGEthe reason customers could not leaveEACH PRICE INCREASE →someonechangesthe rule
Conceptual shape only. No amounts, rates, dates, or results are shown or implied. The horizontal axis counts price increases rather than time, and the lines represent an idea rather than any company, security, or outcome. Nothing is drawn after the rule changes, because what follows depends on the business.
What improvesWhat it looks likeWhat it can also be
MarginDisciplinePrice rising faster than cost, with nothing added
Return on capitalA compounderMore profit on capital that never had to grow
RevenueDemandThe same units at a higher price
Earnings per shareCompoundingBuybacks paid for by the price increases

Every number an investor is taught to watch gets better at the same time. The financial statements do not warn you, because from the inside nothing has gone wrong. The business is doing exactly what it did last year, at a higher price.

4 · When customers push back

In the 1870s, a wheat farmer in Illinois or Iowa usually had one way to get his crop to market, and that was the railroad running past his land. There was no second line and often no river nearby. The railroads knew it and set their rates to match. A farmer on a single line could pay more to ship his grain a short distance than a shipper in a city with several railroads paid to ship much farther.

One farmer could do nothing about it. But thousands of them were paying the same high rates for the same reason, and that gave them something to organize around. Many joined the Grange, a farmers’ association that grew quickly in those years, and took their complaint to their state legislatures. Several states passed laws limiting what railroads could charge. In 1887 Congress passed the Interstate Commerce Act, which put railroad rates under federal oversight for the first time.

Nothing about the trains had gotten worse. The railroads had charged enough, for long enough, that farmers who had never agreed on much found a reason to act together.

The same thing can happen to a business today. When customers have no alternative and prices keep rising, they start comparing notes, and competitors, middlemen, and regulators all find reasons to take their side. The rule protecting the business is rarely repealed outright. More often, whoever controls it makes the alternative easier or cheaper to choose, and the protection fades. The faster prices rise, the sooner that happens.

5 · What the company would say

A company that raises prices this way usually has a real defense. Its product may be better than the alternative. It may keep only a small part of what the customer finally pays, with most of the cost added by others along the way. Some of its loudest critics may have interests of their own. Even if every one of those points is right, the result is the same: prices that rise this fast give the people who can change the rule a reason to change it.

6 · Businesses that lower prices instead

Nick Sleep, a British fund manager legendary among a small group of value investors, ran a concentrated investment partnership for more than a decade and looked for companies that did the opposite of flexing their pricing power. He found companies that grew their competitive advantage, their “moat,” by growing larger and cheaper to run while passing the savings to customers as lower prices. That held margins, and the other measures investors watch, down for a while, but it made those businesses harder to compete with every year.

Customers whose prices keep falling do not organize against the company. Nobody writes to a legislator about a bill that keeps getting smaller. Keeping the savings as profit produces better numbers now and more opposition later, and the choice management makes tells you if it is running the business for this year or for the long run. Evaluating Management covers how to read that choice.

7 · What to watch

SignalWhy it matters
Price rising much faster than volumeGrowth is coming from existing customers, not new demand
Margins rising with no change to the productThe increase is being kept, not reinvested
The defense is that the charge is smallIt answers the size of the charge and avoids how fast it is rising
Customers complaining in publicThey are building a record someone else can use
The advantage depends on a ruleWhoever wrote the rule can change it
A valuation that assumes the pace continuesIt has already paid for increases that have not happened yet

8 · The investor’s mistake

A high valuation on a business with real pricing power is often deserved. Many of the businesses the market has called compounders earned their premiums for years. The mistake is assuming the price increases that produced those years can keep coming at the same pace.

Investors are part of the pressure on management. They reward it for raising prices, bid the shares up as each increase arrives, and then pay a valuation that only works if the increases continue. If the response comes, the valuation can fall much further than the business does, because the price had already paid for years of increases that may not happen.

The Direction of a Moat asks if a moat is getting stronger or weaker. Here the moat looks stronger than ever while it is being used up.

Where this lands

Pricing power is worth a great deal, and using it has to be balanced against keeping it. A business that raises prices in step with what it gives customers can keep doing so for a long time. A business that raises them faster can report excellent results for years while shortening its own runway, and the financial statements will look the same in both cases. What tells them apart is where the advantage came from, who could take it away, and how quickly the price increases are giving someone a reason to.

What to carry away
  • Pricing power shows a moat exists, and each increase uses some of it up.
  • Growing volume needs new customers. Raising a price needs only that existing customers cannot or will not leave.
  • Management is pushed from both sides: use pricing power too hard and customers, regulators, and competitors push back; never use it and investors may push for new management.
  • An earned advantage is beaten by a better product. A granted one is beaten by changing the rule.
  • While a moat is being spent, margins, returns on capital, revenue and earnings per share all improve at once.
  • Fast increases on customers with no choice organize the people who can change the rule.
  • Passing savings back to customers keeps a moat quiet. Keeping them as margin makes it a target.
  • The investor’s mistake is paying a valuation that needs the increases to continue.
