For owners of profitable Southern California businesses preparing for an exit, few levers move the sale price like the careful handling of add-backs. One-time expense add-backs — removing genuinely non-recurring legal, technology, and other costs from your reported earnings — can raise your adjusted EBITDA, and because buyers pay a multiple of that number, the effect on your enterprise value is amplified. Done right, they recover value you actually earned. Done sloppily, they hand a buyer a reason to discount your whole story.
This article explains how to identify, document, and defend one-time expense add-backs so a sophisticated buyer in Los Angeles, Orange County, San Diego, or the Inland Empire accepts them rather than crossing them out. The goal is a clean, credible bridge from your tax return to the earnings a buyer is willing to pay for.
What one-time expense add-backs actually are
Normalizing earnings versus inflating them
An add-back adjusts your historical earnings to reflect what the business would have earned under normal, ongoing operations. A legitimate one-time expense add-back removes a cost that genuinely will not repeat for the new owner: a lawsuit you settled, a software system you installed once, a flood you cleaned up. The line that matters to a buyer is simple — would this cost recur if they ran the business next year? If the honest answer is no, it is a defensible add-back. If it is “probably, in some form,” it is not. Buyers and their accountants are paid to be skeptical, so the burden of proof sits with the seller.
Why the multiple makes every add-back matter
Established lower-middle-market businesses typically sell for roughly three to five times adjusted EBITDA. That multiple is exactly why add-backs are worth the effort: every dollar you correctly add back is multiplied at closing. A single $50,000 non-recurring cost left buried in your financials is not a $50,000 problem — at a 4x multiple it is a $200,000 reduction in your sale price. Conversely, a clean and well-supported set of add-backs can be one of the highest-return tasks you complete before going to market. The same discipline that helps you understand what a broker’s success fee would cost you — our Broker Fee Savings Estimator lays that out — should be applied to knowing what each add-back is worth to your final number.
Which add-backs survive, and which do not
Non-recurring legal and settlement costs
California is an expensive place to be sued. Employment claims under the Private Attorneys General Act (PAGA), wrongful-termination suits, and contract disputes generate legal bills that have nothing to do with normal operations. A one-time settlement and the outside counsel fees tied to it are classic add-backs. The key distinction: the litigation was a one-off, but if you face employment claims every other year, a buyer will treat that as a recurring cost of operating in California and reject the add-back. Document the matter, the resolution, and why it will not repeat. The same logic applies to one-time costs of defending a since-resolved wage-and-hour audit or a single intellectual-property dispute — both can occur for SoCal employers and both can be legitimate non-recurring items when properly evidenced.
One-time technology and systems investments
A new ERP rollout, a website rebuild, or a one-time cybersecurity remediation are commonly added back when they are genuinely non-recurring capital-like expenses run through the income statement. An Irvine professional-services firm that spent heavily implementing a new practice-management platform in a single year has a strong add-back, provided the ongoing license and maintenance fees stay in the numbers as a normal operating cost. The trap is adding back the whole technology line when part of it is recurring subscription spend the buyer will keep paying.
Other genuine one-offs
A move out of a high-rent Los Angeles or Orange County facility, wildfire or mudslide remediation of the kind that periodically hits inland and foothill communities, severance from a one-time restructuring, and certain pandemic-era costs can all qualify. The standard never changes: the expense must be clearly identifiable, supportable with documentation, and unlikely to recur for the new owner. Vague “miscellaneous” add-backs are the fastest way to lose credibility on the entire schedule.
The add-backs buyers routinely reject
Knowing what not to claim protects the lines that are real. Buyers consistently strike out adjustments for costs that simply belong to running the business: routine repairs dressed up as “one-time,” annual bonuses relabeled as discretionary, marketing experiments that are really ongoing spend, and personal expenses that should be handled separately rather than smuggled into the add-back schedule. A useful self-test is to ask whether you would be comfortable walking a buyer’s accountant through the invoice line by line. If a particular add-back makes you hesitate, leave it off — one indefensible line can cast doubt on the ten good ones beside it. Restraint is credibility, and credibility is what protects your multiple.
A worked example: what the add-backs are worth
Consider an established Anaheim manufacturer with $2,000,000 of reported EBITDA and three genuine non-recurring costs in its most recent year.
| Line item | Amount |
|---|---|
| Reported EBITDA (most recent fiscal year) | $2,000,000 |
| Add back: one-time employment-law settlement & counsel | $150,000 |
| Add back: one-time ERP implementation | $120,000 |
| Add back: one-time facility relocation | $80,000 |
| Adjusted EBITDA | $2,350,000 |
The three add-backs total $350,000. At a 4x multiple, that $350,000 of correctly documented one-time costs adds $1,400,000 to enterprise value — the difference between an $8.0M and a $9.4M outcome. That is the entire case for taking add-backs seriously: the work is measured in hours, and the payoff is measured in hundreds of thousands of dollars.

How to document add-backs so they survive due diligence
Build the evidence file before you go to market
Every add-back needs a paper trail: the invoice or settlement agreement, the general-ledger entry, and a short written explanation of why the cost will not recur. Assemble this evidence file before a buyer ever asks. A schedule of one-time expense add-backs that is backed by source documents is treated very differently from a list of round numbers a seller produced from memory. The first is a negotiation you win; the second is a credibility problem that can spread doubt across your entire financial presentation.
Timing matters too. Most buyers look at three years of financials, so an add-back in your most recent year carries more weight than one buried two years back, and a cost that appears every single year is no longer “one-time” by definition. Start tagging non-recurring items in your general ledger now, in the ordinary course, rather than reconstructing them under deal pressure. Owners who prepare their add-back schedule a year or more ahead of a sale almost always defend it more successfully than those who scramble once a buyer is at the table.
Expect a quality-of-earnings review to test every line
In any serious transaction, a buyer will commission a quality-of-earnings analysis, and that team will test each add-back against the underlying records. Aggressive or unsupported adjustments get stripped out, and a pattern of them invites a broader discount. This is also where dealing directly with a single, funded buyer helps: instead of defending your add-backs to an anonymous pool of bidders surfaced by a public listing, you are working through the schedule once, transparently, with the one decision-maker who will actually own the business. A neutral primer on how adjusted EBITDA is calculated can help you frame the conversation, but the documentation is what carries it.
