⚙️ Before You Begin
Start with clarity about the scope of the carve-out: legal entities, business units, products, and geographies that are in or out. You can’t build a credible cash flow forecasting model if you’re unsure which costs and revenues belong to the carved-out perimeter. Obtain a baseline P&L and cash flow statements for the perimeter, even if they’re pro-forma. Where data doesn’t exist, agree on pragmatic allocation rules with finance and auditors.
Next, gather details on shared services and infrastructure: IT platforms, HR, payroll, facilities, and corporate overheads. Many of these are temporarily covered by TSAs; your standalone cash flow model needs to show both TSA coverage and the future replacement costs. Collect vendor contracts, headcount lists, and overhead allocation policies.
You’ll also need a view of future operating model design-what the carved-out entity will look like in 12-24 months. This informs your target cost base and synergy/dissynergy assumptions. Finally, confirm modeling tooling and governance: version control, owner, and where the carve-out model will live alongside other company valuation methods. Ideally, it sits on the same platform as your DCF and M&A models, not as a one-off spreadsheet.
🧭 Step-by-Step Instructions
Step 1: Define carve-out perimeter and baseline economics
Start by building a perimeter tab that lists in-scope entities, products, customers, and locations. Reconcile this to the deal perimeter in the SPA. From there, construct a baseline P&L and cash flow statements for the carve-out using historical data, allocations, and management estimates. This is your “as-is” view before TSAs and standalone changes.
Ensure the baseline cash flow model aligns with the broader acquisition model: revenue growth, margin assumptions, and capex should be consistent with CIM-based work. Where you rely on allocations, flag them explicitly so you can revisit later. The goal is not perfection; it’s a coherent starting point that management and investors agree is “good enough” to explore standalone and dissynergy scenarios.
Step 2: Identify shared services, TSAs, and replacement costs
List all shared services the carve-out currently consumes: IT systems, finance, HR, facilities, legal, and group management. For each, specify whether support continues via TSA, is replaced by new third-party vendors, or is brought in-house. Link the TSA services to the TSA schedule you modeled separately.
For replacement costs, estimate future run-rate using a simple cash flow forecasting model: headcount times fully loaded cost, vendor pricing, and facilities expenses. Decide when replacement costs start (often overlapping with TSA coverage), and build timelines in your cash flow projection model to show dual running. This is where dissynergies show up: duplicate systems, overlapping staff, and incremental management overhead that doesn’t create new revenue.
Step 3: Model a standalone overhead and management structure
Carve-outs almost always need more standalone overhead than historic allocations suggest. Build a management and G&A plan that includes leadership, finance, HR, legal, and IT. Use driver-based assumptions rather than arbitrary percentages: for example, controllers per entity, HR staff per 100 FTEs, or IT support cost per user. These drivers feed directly into the cash flow model as monthly or quarterly costs.
Where the carve-out is expected to grow, make sure overhead scales appropriately so the discounted cash flow model doesn’t assume impossible leverage. Use your cash flow projection model to test scenarios: lean vs full-service overhead, central vs local teams, and different ramp profiles. Align with M&A accounting and auditors on which costs are one-off transition vs ongoing run-rate.
Step 4: Quantify dissynergies and stranded costs
Isynergies often come from losing purchasing power, breaking scale efficiencies, or duplicating roles. Identify areas where unit costs will rise post-carve-out: procurement, logistics, systems, and management layers. Model these as adjustments to margins and operating costs rather than unexplained “other” lines. This keeps your cash flow statements transparent for lenders and investment committees.
Stranded costs on the seller side can also affect negotiations, even if they don’t sit in your model. Understanding them helps you defend your view of standalone economics in pricing discussions and company valuation methods. Use the cash flow forecasting model to show how dissynergies evolve over time-some may shrink as you renegotiate contracts or rationalise operations, while others are structural.
Step 5: Integrate into the full M&A cash flow and valuation view
Finally, plug carve-out, standalone, and dissynergy modeling into the broader deal model. Ensure TSA, standalone overhead, and dissynergies all feed into one integrated cash flow projection model. From there, generate free cash flows that feed your discounted cash flow model and other company valuation methods.
Check that the story matches adjacent work: TSA modeling, working capital design, and synergy ramp. The output should be a set of clear, time-phased bridges that show how the business moves from group-embedded operations to a truly standalone profile. This is what convinces investment committees, lenders, and management that the carve-out economics are understood and controllable.
⚠️ Tips, Edge Cases & Gotchas
Don’t underestimate dual running. You’ll often pay for legacy systems via TSAs while investing in new platforms. Failing to model this accurately can make early-year free cash look unrealistically strong in your cash flow model. Treat dual running as an explicit scenario you can toggle in the cash flow projection model, not an afterthought.
Watch customer and supplier responses. Carve-outs can trigger re-pricing or churn, which affects both revenue and cash flow statements. Build simple sensitivity cases that show the impact on free cash and valuation. Be transparent about where you’ve used rule-of-thumb adjustments vs hard data; that builds trust in your company valuation methods.
Finally, remember that dissynergies may reverse over time as the standalone business optimises contracts, systems, and headcount. Model a glide path, not a permanent penalty, so your discounted cash flow model isn’t overly pessimistic-or unrealistically optimistic if improvement is unlikely.
📊 Example / Quick Illustration
Consider a manufacturing business being carved out from a conglomerate. Historically, it benefited from group purchasing, shared ERP, and central finance. Your baseline cash flow model uses allocated costs, but post-deal, you’ll stand up your own ERP, hire a finance team, and lose some purchasing discounts.
In your cash flow projection model, you show TSA coverage for ERP and finance during the first 12 months, overlapping with the ramp of new vendors and hires. Procurement costs rise 5-7% as you renegotiate contracts, modeled as margin compression. Over three years, you gradually claw back some of that through operational improvement. The result is a credible discounted cash flow model that reflects both the pain of separation and the upside of focused standalone management, not just a flat uplift on historical cash flow statements.
🚀 Next Steps
With a working carve-out model in place, socialise it with integration, finance, and deal sponsors. Use it to drive decisions on where to insource vs outsource, how quickly to exit TSAs, and which dissynergies deserve active mitigation. Integrate key outputs into the main M&A cash flow dashboard so leaders can see how standalone costs and dissynergies affect free cash and returns.
Next, refine adjacent modules: deeper TSA schedule modeling, transaction costs, and synergy ramp planning. As you complete more carve-outs, update your framework and assumptions so your cash flow model, cash flow statements, and discounted cash flow model all benefit from accumulated learning.
