Capex Due Diligence: Separating Growth Investment from Deferred Maintenance

Capex due diligence should establish how much cash the target needs to sustain current earnings, correct legacy deficiencies, remain compliant and deliver forecast growth. Management labels such as maintenance or strategic are not enough. Investors must trace projects to asset condition and capacity, test full installed cost and schedule, and prevent deferred maintenance from being presented as optional growth investment.

Create an economic capex taxonomy

Classify projects by primary purpose while allowing mixed scope:

• Sustaining: recurring replacement or renewal needed to maintain existing capability.
• Catch-up: work deferred from prior periods to restore assumed condition or reliability.
• Compliance and safety: investment required to meet legal, permit, customer or critical risk controls.
• Growth: additional saleable capacity, product capability or market access.
• Efficiency: lower material, labour, energy, maintenance or cycle cost.
• Discretionary or enabling: facilities, systems or resilience improvements whose return is indirect.

Accounting capitalisation and economic classification answer different questions. A repair may be expensed under the applicable framework but still represent catch-up cash; a capitalised project may merely preserve existing earnings. Accounting advisers should review recognition and measurement, while diligence focuses on purpose, cash and benefit.

Reconcile the historical record

Obtain several years of additions, disposals, capital work in progress, cash-flow statements, project registers and board approvals. Reconcile approved, committed, invoiced, capitalised and paid amounts by project. Trace samples to purchase orders, supplier invoices, goods receipt, installation and commissioning.

Look for:

• projects split below approval thresholds;
• repairs capitalised or capex charged to expense inconsistently;
• long-aged capital work in progress;
• assets capitalised before being ready for intended use;
• projects repeatedly postponed or removed from budgets;
• capex paid by related parties or hidden in leases;
• grants, duties or tax assumptions not reflected in cash.

Compare historical spend with production hours, asset age, maintenance backlog and failures. Low capex can reflect an asset-light model, recent investment or underinvestment; only plant evidence distinguishes them.

Link the plan to asset condition and compliance

For sustaining and catch-up items, reconcile the capital plan with the asset register, condition assessments, maintenance system, statutory inspections and obsolescence roadmap. Challenge whether known defects are omitted, scoped as minor repairs or deferred beyond the investment horizon.

Compliance projects require the same discipline. Identify the legal, permit, safety or customer requirement, required completion date and consequence of delay. Pollution-control or safety investment may also constrain production during installation. Specialist engineers and counsel should determine adequacy; a budget line is not proof of compliance.

Separate the work necessary on day one from prudent lifecycle renewal. ISO 55001's asset-management approach emphasises balancing performance, risk and expenditure over the asset lifecycle, which is more useful than a fixed percentage of revenue.

Validate growth and efficiency projects

For each material project, create an investment case containing:

1. demand or operational need;
2. technical scope and alternatives;
3. bottleneck and system capacity before and after;
4. engineering maturity and vendor quotations;
5. permits, land, utilities and customer approvals;
6. schedule, shutdown, commissioning and ramp;
7. full installed cost and contingency;
8. volume, price, yield or cost benefits;
9. working-capital and recurring-cost consequences.

A new machine does not create growth if the bottleneck moves to testing, utilities or demand. Confirm that customers will approve the new process and that sales assumptions do not exceed saleable capacity. For efficiency, establish the baseline and avoid counting savings already reflected in standards or budgets.

Estimate full installed cost

Vendor equipment price is rarely the total cash requirement. Include design, civil and structural work, electricals, utilities, freight, duties, installation, integration, software, spares, training, validation, trial material, commissioning loss, project management and contingency. Account for foreign exchange and escalation where relevant.

Assess estimate maturity. A preliminary concept with one budgetary quotation needs a wider range than a contracted project with completed engineering. Cross-check recent comparable projects and site constraints, but do not invent precision. Show nominal cash timing because a delayed project can affect both valuation date cash and forecast output.

Test schedule and execution capacity

Review permitting, design release, long-lead items, shutdown windows, contractor capacity, internal engineering resources and dependencies. Check vendor financial health and performance security. A project portfolio can be individually plausible but collectively impossible if every installation needs the same holiday shutdown or engineering team.

Include ramp-up rather than assuming full output on commissioning day. Model training, process stabilisation, scrap, customer approval and working-capital build. EBITDA from growth is not free cash flow.

Build one reconciled capex bridge

Present capex by category, project, year, confidence and downside. Link each amount to sustainable earnings:

Avoid double counting. If a replacement is fully captured in capex and restores forecast output, do not also deduct perpetual downtime. If normal maintenance expense is adjusted in EBITDA, separate it from capital replacement cash.

Use capex evidence in transaction decisions

Findings may change enterprise value, the forecast, net-debt-like or working-capital definitions, conditions precedent, seller covenants, escrow or post-close funding, subject to legal, tax and accounting advice. Clarify who owns committed purchase orders, deposits, grants and partially completed assets at closing.

The first-100-day plan should freeze unsafe deferrals, confirm the capital authority matrix, revalidate major projects and protect critical shutdowns. Shree Sarada's business advisory and reengineering services can help connect capital allocation to the value thesis.

Conclusion

Good capex diligence follows cash from need to commissioned benefit. It distinguishes what preserves the business from what grows it, tests cost and execution, and ensures the valuation does not rely on earnings that require unfunded investment.
