Acquisitions Are Made or Lost on the Model

Every Australian merger or acquisition begins with a financial model. The acquirer needs to know: what is this business worth as a standalone entity, what synergies can realistically be captured and over what timeline, how does the acquisition affect the combined entity's financial position, what is the maximum price that can be justified at the required return, and how is the deal being funded - and what does the funding structure do to the balance sheet and the debt service capacity?

These questions cannot be answered by a pitch deck. They require a financial model built specifically for the transaction - one that combines the standalone valuation of the target, a rigorous synergy analysis, a combined entity forecast, and the financing structure - with the discipline and rigour that a transaction of this significance demands.

Buy-Side Financial Modelling

A buy-side M&A model is built for an acquirer evaluating a potential acquisition. Its core components: a standalone valuation of the target business using DCF and comparable company analysis; a synergy model identifying, sizing, and phasing the cost and revenue synergies expected from the combination; a combined entity financial model integrating the acquirer and target financials with synergies overlaid; an acquisition accounting model capturing the purchase price allocation and goodwill; and a returns analysis showing the equity IRR and cash-on-cash multiple at the proposed acquisition price and financing structure.

Sell-Side Financial Modelling

A sell-side M&A model is built for a business preparing for sale - to support the information memorandum, to anchor the valuation discussion with potential acquirers, and to demonstrate the financial quality and growth trajectory of the business in a format that sophisticated buyers can interrogate.

LBO Modelling

An LBO model is the standard financial model for private equity transactions - where the acquisition is funded primarily with debt, and the returns are driven by the combination of cash flow generation (used to repay the debt) and value creation in the business over the investment horizon. The model must demonstrate that the business can service the acquisition debt under a range of economic scenarios, and that the equity investment generates the required return at the expected exit multiple and timeline.

What the Model Must Demonstrate

Regardless of transaction type, the financial model that supports an M&A process must answer the same fundamental questions with enough rigour to withstand scrutiny from the other side of the table and from the advisers and lenders involved in the transaction.

The starting point is always the target's standalone financial position. Before synergies, before deal structure, before financing - the acquirer needs to understand what they are buying. This requires business valuation modelling of the target as an independent entity: a DCF built on a defensible set of revenue and cost assumptions, a comparable company analysis benchmarked against relevant peers, and a valuation range that reflects genuine uncertainty in the key inputs rather than false precision around a single number.

The combined entity forecast requires a three-way financial model for the target or combined entity - an integrated P&L, cash flow statement, and balance sheet that shows how the two businesses perform together under the proposed acquisition structure. This is where the interaction between synergies, acquisition debt, and working capital becomes visible: a combined entity that looks profitable on a P&L basis can still face cash flow pressure in the integration period if the debt service burden is heavy and the synergies take longer to realise than planned. A three-way integrated structure shows this. A standalone P&L does not.

Uncertainty about synergy timing, integration costs, and market conditions makes scenario and deal structure analysis a core component of every serious M&A model - not an optional add-on. What does the acquirer's equity IRR look like if synergies are realised 12 months later than planned? What is the maximum purchase price at which the deal still clears the required return threshold, across a range of exit multiples? What happens to the combined entity's debt service coverage if revenue comes in 15 percent below the base case? These questions need answers before the deal is executed.

When a Valuation Model Is Required

Buy-side: evaluating an acquisition target, sizing synergies, stress-testing deal structure and financing.

Sell-side: preparing for sale, anchoring the valuation discussion, building the information memorandum financial model.

Private equity: LBO modelling, returns analysis, debt serviceability assessment.

Management buyouts: management team acquiring the business from its current owner, typically with a combination of equity and acquisition debt.

Joint ventures and mergers: modelling the combined entity under different contribution and governance structures.

Who We Work With

Wiseworth builds M&A financial models for Australian businesses across a range of transaction types and sectors. Two industries with consistently active transaction pipelines in Australia are fintech and technology businesses — where acquirer appetite from both strategic buyers and private equity remains strong, and where the financial model must translate recurring revenue metrics and growth trajectories into a defensible valuation for a sophisticated counterparty — and property and PropTech transactions, where site acquisitions, platform consolidations, and development joint ventures each require a transaction model that correctly captures the capital structure, the development timeline, and the distribution waterfall between equity partners.
