The Anchoring Effect: The Number That Sinks Your Sale

It usually starts at a conference. Someone at the bar mentions what a firm "like yours" sold for, as a multiple, and the owner does the math on a napkin. From that moment, that number is what the firm is worth. Months later a private equity group calls, the offer lands somewhere in the neighborhood, and the owner says yes to the first buyer who asked. That's anchoring bias in business valuation: the first number you hear sets the range for every number after it. In the phase of business where an owner prepares to sell or hand off the firm, it decides the biggest check most owners will ever cash. In public adjusting, I'm already watching it go badly for some of the owners who sold first.

This is article six of a seven-part series pairing each phase of the 7Seas of Entrepreneurship with the cognitive bias that shows up there most often.

The Selling Sea Means Selling the Firm

In the 7Seas framework, the Selling Sea means preparing the business for a transition: a sale, a succession, or a handoff to a leadership team. It has nothing to do with sales technique. Two things carry the load here: documented operations and proof that the firm keeps producing. In 7Seas terms, those are Process and Progress, the mainsail. The story about the firm, meaning its purpose and how the market reads it, gets positioned for a buyer or successor. That's Purpose and Perception, the headsail. The machine leads and the story follows.

The framework names the mistake that keeps owners stuck in this Sea: leading with the story. Buyers price the machine, and a story nothing supports falls apart in due diligence. An anchored number is a story too. It's the story of what the owner believes the firm is worth, built before anyone looked at the machine.

What the Research Says About Anchoring Bias in Business Valuation

Amos Tversky and Daniel Kahneman showed how little it takes in their 1974 paper Judgment Under Uncertainty: Heuristics and Biases. People watched a wheel of fortune land on a number, then estimated the percentage of African countries in the United Nations (54 countries out of 193 - approximately 28% if you were curious...) Their estimates drifted toward whatever number the wheel showed, even though they knew the wheel was random.

Expertise doesn't fix it. Gregory Northcraft and Margaret Neale tested real estate agents in a study published as Experts, Amateurs, and Real Estate in 1987. Experienced agents toured the same house with the same information, except for the listing price they were handed. Their appraisals moved with that listing price, and most of them said it hadn't influenced their judgment. If a random wheel can move a guess and a listing price can move a professional appraisal, a multiple overheard at a conference can move an owner's sense of what their life's work is worth.

Three Anchors Owners Price Their Firms From

The conference multiple. This is the one I see most. It comes from a different firm, with a different book of business, a different market, and a different deal structure, and the owner hears only the headline number. Nobody at the bar mentions how much of that price was paid at closing, how much was tied to future performance, or what the seller gave up to get it.

The retirement number. This is what the owner needs to walk away, and it has nothing to do with what a buyer will pay. It sets a floor in the owner's head that the business may not support. Owners anchored on a retirement number tend to accept terms that look like they reach it, without checking whether they actually will.

The hot year. This is the most dangerous anchor. An owner values the firm off revenue from a big storm year, or a year when a referral channel ran hot, and treats a peak as normal. The firms I've watched value themselves on a hot year are struggling now. It's also the halo effect from article two of this series, applied to a price tag: one great year makes everything about the firm look worth more than it is.

The First Offer Becomes the Deal

An owner anchored on a number hears an offer near it and says yes, often to the first private equity group that calls. There are no competing offers and no independent valuation. And the documented, audit-ready operation that the Selling Sea's mainsail calls for usually hasn't been built.

In public adjusting, the price isn't what's killing these deals. The terms are. Rollover equity, where part of the price comes back to the seller as ownership in the new company rather than cash. Share types, where the seller's shares sit behind other classes when money gets paid out. Earn-outs, where a big piece of the price depends on future results the seller no longer controls. And how EBITDA growth gets defined and measured, which decides whether those earn-outs ever pay. An owner focused on the headline number signs past all of it. Owners and founders from some of the very first public adjusting firm acquisitions are now being pushed out of the companies they built, and walking away with far less than the number they agreed to.

First-party law firms face a different picture. Most states restrict non-lawyer ownership of law firms under rules based on the ABA Model Rules of Professional Conduct, a few states have opened alternatives, and those rules are changing. The anchoring problem is the same, but the buyers and deal structures available to a law firm depend on where it practices.

What a Firm Priced Without an Anchor Looks Like

The 7Seas framework describes how the Selling Sea ends: either the transaction closes, or the preparation makes the firm so independent of the owner that selling becomes optional. That second outcome is the door into the Sailing Sea, and plenty of owners who prepare well decide they'd rather keep the firm.

At the owner level, it looks like this. The firm's value comes from its own documented numbers across normal years, not a peer's headline or a single hot year. The operation is documented well enough that a buyer is pricing a machine. More than one buyer gets a look. The owner understands the terms as well as the price, including what happens to rollover equity, which shares they hold, how the earn-out is measured, and whether they'll still have a seat at the table in three years. And the retirement number gets planned for separately, instead of quietly setting the floor for the deal.

Seeing the Anchor Is Free. Getting the Deal Right Is the Work.

Knowing about anchoring won't value your firm or read a term sheet. That takes specialized help, which is why TAA works with a trusted M&A partner who knows this industry and these deals.

Next article, the series closes its seven pairings with the Sailing Sea, where owners who've made it teach from the one path that worked and survivorship bias hides every path that didn't.
