Economic and financial feasibility studies

Economic and financial modeling for confident decisions: build, expand, overhaul, buy or decommission — with NPV, IRR, scenario analysis and technical assumptions verified in the field.

Before investing, the right question

Every significant investment decision — building a plant, expanding capacity, replacing a line, buying a venture — comes down to one question: does the project create value? The feasibility study exists to answer that question methodically, before the capital is committed.

The difference between a reliable study and an optimistic spreadsheet lies in the assumptions. Volume, price and margin may come from the market; but effective capacity, maintenance cost, asset useful life and reinvestment needs are engineering assumptions — and that is exactly where Stima combines financial modeling with technical verification in the field.

When the study is required

  • Investment decisions — building a new plant, capacity expansion, vertical integration, automation and energy efficiency projects.
  • Overhaul or replace — economic comparison between the retrofit of an existing asset, buying new and acquiring used, with the full life-cycle cost.
  • Purchase and sale of ventures — price setting, appraisal of going concerns and analysis of asset portfolios.
  • M&A transactions — economic and financial due diligence and independent verification of the technical assumptions in the business plan.
  • Restructuring and decommissioning — keep operating, mothball or shut down: economic quantification of each alternative.
  • Financing and collateral — studies supporting project finance and structured transactions.

What we do

  • Project modeling — discounted cash flow with NPV, IRR, discounted payback and profitability index, in an open and auditable model.
  • Scenario and sensitivity analysis — optimistic, base and pessimistic scenarios, break-even points and the critical drivers of the result.
  • Appraisal of ventures and businesses — discounted cash flow, market multiples and net asset value, depending on the purpose.
  • Technical verification of assumptions — on-site inspection of the assets, installed and effective capacity, remaining useful life, maintenance capex and asset-related liabilities.
  • Studies of alternatives — overhaul vs. replace, buy vs. lease, operate vs. decommission, with a substantiated recommendation.
  • Decision support — executive presentation for the board of directors, the board or the investment committee.

Methodology

  1. Understanding the project — the decision's objective, the alternatives under analysis, the appraisal horizon and capital constraints.
  2. Technical diagnosis — on-site inspection and characterization of the assets involved, capacity, state of repair and reinvestment needs.
  3. Assumption building — volumes, prices, fixed and variable costs, capex, working capital and taxation, with the source of each assumption documented.
  4. Modeling — project and equity cash flows, a discount rate consistent with the risk, an explicit horizon and a substantiated terminal value.
  5. Scenarios and sensitivity — simulation of the critical variables and identification of the decision's break-even points.
  6. Report and presentation — assumptions memorandum, open model, conclusion and recommendation, with a presentation to the decision makers.
Feasibility is not impairment. The feasibility study looks forward and answers whether a new investment is justified. The impairment test looks at the assets already on the balance sheet and verifies whether the carrying amount holds up, in accordance with CPC 01 / IAS 36. They are distinct services, each with its own standard, purpose and deliverable — and Stima provides both.

Frequently asked questions

Questions about economic feasibility studies

What is the difference between a feasibility study and a valuation?

A valuation answers how much a business or asset is worth today. A feasibility study answers whether a future investment creates value — comparing the capital to be invested with the cash flow the project is expected to generate. The techniques overlap (discounted cash flow in both), but the question and the deliverable differ. We do both, depending on what the decision requires.

Can the study be presented to a bank or investor?

Yes. The model is delivered open and auditable, with an assumptions memorandum and a documented source for every number — the format credit committees, funds and investors expect to examine. The on-site technical verification of the assets is a differentiator over purely financial studies.

Why involve engineering in a financial study?

Because the assumptions that most distort a feasibility study are physical: effective capacity lower than nameplate, maintenance costs rising with age, overestimated useful life and ignored replacement capex. The on-site technical inspection anchors these assumptions in the reality of the asset — and that is what separates a defensible projection from an optimistic spreadsheet.

Do you analyze alternatives, or only the project as presented?

We analyze the alternatives relevant to the decision: overhaul versus replace, buy versus lease, expand versus outsource, operate versus decommission. The report presents the economic outcome of each path and a substantiated recommendation.
