From SBA financing and seller notes to earnouts tied to patient retention — a practical guide to deal structures for audiology practice buyers in the $1M–$5M revenue range.
Acquiring a hearing center involves navigating deal structures that reflect the industry's unique dynamics: high owner-dependency, recurring revenue from patient follow-up and device upgrades, and regulatory complexity around Medicare billing and manufacturer agreements. Most transactions in the $1M–$5M revenue range combine SBA 7(a) financing with a seller note and, increasingly, an earnout component tied to patient retention or hearing aid unit sales. The goal of any well-structured deal is to align seller and buyer incentives through transition, protect the buyer against patient attrition risk, and ensure the departing audiologist remains engaged long enough to transfer patient trust and referral relationships. Multiples for hearing centers typically range from 3.5x to 6x EBITDA depending on practice size, revenue diversification, compliance record, and the degree of owner dependency — making deal structure a powerful lever for bridging valuation gaps.

The buyer pays the entire purchase price at closing, typically funded through a combination of equity and SBA or conventional debt. No deferred consideration is involved. This structure is cleanest for sellers but places maximum risk on the buyer, who inherits full exposure to post-close patient attrition, reimbursement changes, and staff continuity from day one.
Pros
Cons
Best for: Well-documented hearing centers with an associate audiologist already in place, diversified revenue across insurance, self-pay, and hearing aid sales, and a clean Medicare billing history that reduces transition risk.
SBA 7(a) Loan with Seller Note
The most common structure for independent hearing center acquisitions in the lower middle market. The buyer contributes 10–20% equity, finances 70–80% through an SBA 7(a) loan, and the seller carries a subordinated note for the remaining gap — typically 5–15% of the purchase price. The seller note is often on standby for 24 months per SBA requirements, meaning no payments flow to the seller during that period.
Pros
Cons
Best for: First-time buyers with healthcare operations backgrounds acquiring a single hearing center location, or audiologists seeking ownership who qualify for SBA financing but lack the capital for a full cash transaction.
Earnout Structure
A portion of the purchase price — typically 10–25% — is deferred and paid to the seller based on the achievement of specific post-close performance milestones. In hearing center deals, earnouts are most commonly tied to patient retention rates, hearing aid unit sales volume, or total revenue over a 12–24 month measurement period. Earnouts are used to bridge valuation gaps when the buyer and seller disagree on the sustainability of current revenue.
Pros
Cons
Best for: Acquisitions where the selling audiologist is the sole provider, where a significant portion of revenue is tied to that individual's patient relationships, or where there is meaningful disagreement between buyer and seller on a sustainable revenue run rate.
Full Acquisition with Seller Stay-On as Clinical Director
The seller is acquired outright at closing but is retained under an employment or consulting agreement as clinical director or lead audiologist for a defined transition period — typically 12–24 months. The seller receives a market-rate salary or consulting fee during this period. This structure is specifically designed to address patient attrition risk in relationship-driven audiology practices where patients follow their audiologist.
Pros
Cons
Best for: Single-provider hearing centers where the selling audiologist has 20+ years of patient relationships, practices with a loyal senior patient base on long upgrade cycles, or acquisitions by private equity roll-up platforms building a regional audiology network.

Hearing centers in the lower middle market typically trade at 3.5x to 6x EBITDA. A single-provider practice with owner dependency, outdated equipment, or inconsistent revenue will price toward the lower end of that range, while a multi-audiologist group with diversified revenue, clean Medicare compliance, and documented patient retention rates will command multiples at or above 5x. Revenue multiples are less commonly used but generally fall in the 0.8x–1.5x range for practices in the $1M–$5M revenue band.
Yes — hearing centers are SBA-eligible businesses, and SBA 7(a) loans are the most common financing mechanism for individual buyers in the $1M–$3M purchase price range. SBA lenders will typically require 10–20% buyer equity injection, a debt service coverage ratio of at least 1.25x, three years of CPA-prepared financial statements, clean Medicare billing history, and confirmation that audiologist licenses are current and transferable. The SBA also allows seller notes to count toward the equity injection in certain structures, which can reduce the buyer's out-of-pocket requirement at close.
The most effective protections are structural: negotiate a seller stay-on agreement that keeps the departing audiologist in a visible clinical role for at least 12–18 months, tie a portion of the purchase price to an earnout based on patient retention rates measured at 12 and 24 months post-close, and ensure the seller sends a warm introduction letter to the active patient base announcing the transition. Additionally, verify during due diligence that patient records are well-documented, appointments are pre-scheduled, and at least one associate audiologist is already known to patients — reducing dependency on any single provider.
Effective earnouts in hearing center acquisitions are tied to measurable, objective metrics such as hearing aid unit sales volume, total insurance reimbursement received, or active patient visit counts over the earnout period. Avoid vague revenue targets that can be affected by buyer decisions around pricing or marketing. Define the measurement period clearly — typically 12 or 24 months post-close — specify the reporting methodology, and give the seller reasonable audit rights over the relevant financial data. Earnouts typically represent 10–25% of the total purchase price and pay out in one or two tranches.
Manufacturer agreements — including exclusivity obligations, rebate tier structures, and preferred provider status — can significantly affect post-close margins and flexibility. Buyers should review all agreements during due diligence and determine whether they are assignable to a new owner entity. If a practice is heavily dependent on rebates tied to a single manufacturer's volume targets, the buyer needs to model whether those volume levels are sustainable post-transition. In some cases, a seller indemnity or price adjustment may be appropriate if a key manufacturer agreement cannot be transferred or if rebate eligibility will reset at close.
A seller note is a form of deferred consideration where the seller effectively lends a portion of the purchase price to the buyer, to be repaid over time with interest. In SBA-financed hearing center deals, seller notes typically represent 5–15% of the purchase price, carry interest rates of 5–7%, and are placed on a 24-month standby period per SBA requirements — meaning no principal or interest payments are made during that window. After standby, the note amortizes over 2–5 years. Seller notes signal seller confidence in the business and improve overall deal feasibility by reducing the buyer's required equity injection at closing.
