Most business owners assume they will eventually sell. But for many, the most obvious exit paths do not fit. No qualified outside buyer. Successors who want the business but cannot purchase it. An ESOP that does not match the company profile. For owners in that position, the planning conversation has to start with a different question: what structure actually works here?
The OldCo / NewCo approach is one answer. At the May 2026 NJ BEI chapter meeting, the group worked through a five-step case study applying this planning architecture to a real commercial HVAC business. This article covers what the structure is, how it works, and when it makes sense.
Midwest Mechanical, Inc. is a commercial HVAC installation and service company structured as an S-Corp. Robert Callahan is 63, the sole owner, and has operated the business for 28 years. The company generates $12.5 million in revenue, $2.1 million in EBITDA, and carries an enterprise value of approximately $8.4 million at a 4x multiple.
The business holds $3.2 million in equipment and vehicles plus $1.8 million in owner-held real estate. Robert’s two children, Sarah (38, VP Operations) and Daniel (34, Service Manager), are active in the business and want ownership. They do not have the capital to buy it. Robert’s stock basis is $420,000 against an $8.4 million enterprise value.
A traditional third-party sale would generate a taxable gain of roughly $8 million. An ESOP is not the right fit for this profile. OldCo / NewCo fits.
OldCo / NewCo is a planning architecture, not a single tax rule. The goal is to transfer a business while addressing three things at the same time: ongoing operational liability, the tax cost of transferring hard assets, and who receives cash flow going forward.
It works especially well for asset-intensive businesses where value is tied to physical assets, equipment, vehicles, real estate, and infrastructure, rather than long-term contracts or personal goodwill. In a service company where revenue depends on relationships that belong to the owner personally, goodwill may not be transferable. Hard assets are. Separating them creates planning options.
Step one is assessing the asset picture. The first move is understanding what the business owns and how those assets are classified. For Midwest Mechanical, that includes $3.2 million in equipment and vehicles plus $1.8 million in real estate Robert owns directly. With a stock basis of $420,000 against an $8.4 million enterprise value, the structure must account for that spread.
Step two is creating NewCo. NewCo is a new entity, typically owned by the successors or a combination of the successors and the departing owner depending on the plan design. This entity will eventually operate the business. Because Sarah and Daniel have no capital to purchase the business outright, the structure allows them to acquire ownership incrementally through the transfer of operations rather than a direct purchase.
Step three is separating operating assets from the hard asset base. OldCo retains the hard assets, specifically the real estate, equipment, and vehicles. NewCo operates the business. NewCo leases the assets from OldCo at a market rate. That lease arrangement creates a cash flow stream to OldCo, which Robert controls. It also keeps operational liability in NewCo, where Robert no longer has ownership exposure.
Step four is structuring the intercompany transactions. This is where the specific IRC provisions matter. The asset transfer itself and the ongoing lease arrangement between related entities are governed by rules that require careful planning. Pre-LOI tax strategy is critical here. Once a letter of intent is signed, restructuring options narrow significantly. The longer the planning runway, the more options the owner has.
Step five is redirecting cash flow on the owner’s terms. OldCo continues to receive lease income from NewCo. Robert controls that income and can use it to fund personal financial goals, including retirement income, estate planning, or other transfers. The lease arrangement can be structured to wind down or transfer over time, completing the ownership transition while managing Robert’s ongoing income and tax position.
OldCo / NewCo is not the right answer for every business. It works best when the business is asset-intensive and value is tied to hard assets rather than transferable goodwill. It also fits when the owner wants to transfer to family members or internal successors who lack the capital to purchase outright, when a traditional sale or ESOP does not match the business profile or the owner’s goals, and when the owner has meaningful capital gains exposure on a direct sale.
Sufficient planning time matters. This structure benefits from several years of runway before the desired transition date. It is less likely to fit when business value is primarily goodwill-dependent, when there is no clear successor, or when the owner needs a full liquidity event in the near term.
Opening this conversation with a client requires preparation. Advisors who raise OldCo / NewCo without understanding the business specifics will lose credibility quickly. The starting point is a working estimate of enterprise value and the hard asset component, the owner’s stock or equity basis, a clear picture of who the intended successors are and their financial position, a sense of the owner’s income needs in the years following transition, and coordination among the attorney, CPA, and financial advisor. This structure requires all three working together.
One observation from the May chapter discussion: many businesses, even larger ones, do not have the operational and succession foundation in place before they think about exit planning. Getting that foundation right has to happen before the technical structures can fully work.
The most consistent theme in the chapter discussion was timing. Every planning structure, including OldCo / NewCo, works better when advisors are in the room before the owner is ready to move. A business worth $8 million today may look different in three years if cash flow has been optimized, key leadership is in place, and the asset structure has been cleaned up. The planning process itself can improve the outcome, not just optimize the transfer.
For Robert, the goal is not just a transfer to Sarah and Daniel. It is a transfer that preserves his income, reduces his tax exposure, keeps the family in control of the business and its assets, and gives the next generation a viable operating company. That outcome requires coordination. Attorney, CPA, financial advisor, and business advisor working from the same plan.
If you work with business owners in asset-intensive industries, the OldCo / NewCo framework is worth adding to your planning toolkit. Start by identifying clients where the current exit path does not fit. Owners with low stock basis, hard asset concentration, family successors, and no clear liquidity path are the most likely candidates.
Bring in the right advisors before the conversation becomes urgent. The planning window is the variable you can control.
