A Company Has An 11% WACC And Is Considering Two Mutually Exclusive Investments (that Cannot Be Repeated)

When a company faces the decision to undertake investments, understanding the implications of its Weighted Average Cost of Capital (WACC) becomes crucial. In this scenario, a company with an 11% WACC is evaluating two mutually exclusive projects—meaning only one can be chosen, and once selected, the other is discarded. Making the right choice requires a thorough analysis of each project’s expected returns, risks, and how they align with the company’s strategic goals. This article explores how to evaluate such investment options effectively, taking into account the company's WACC, and provides insights into making optimal investment decisions under these circumstances.

Understanding WACC and Its Role in Investment Decisions

What Is WACC?

The Weighted Average Cost of Capital (WACC) is the average rate a company expects to pay to finance its assets through a combination of debt and equity. It reflects the minimum return required by investors and creditors to compensate for the risk associated with the company’s operations. The WACC serves as a benchmark in investment appraisal, helping determine whether a project’s expected return exceeds the company's cost of capital.

Why Is WACC Important in Investment Analysis?

  • Benchmark for Investment Returns: Projects should ideally generate returns above the WACC to create value.
  • Risk Adjustment: WACC incorporates the risk profile of the company's capital structure.
  • Decision-Making Tool: It aids in comparing potential investments, especially when projects are mutually exclusive and cannot be repeated.

Evaluating Mutually Exclusive Projects with an 11% WACC

When choosing between two projects, especially when they are mutually exclusive, the primary goal is to identify which project adds the most value to the firm. The evaluation process involves calculating key metrics such as Net Present Value (NPV), Internal Rate of Return (IRR), and considering qualitative factors.

Calculating Net Present Value (NPV)

NPV measures the difference between the present value of cash inflows and outflows discounted at the WACC:
    • Positive NPV: The project is expected to generate value over its cost of capital.
    • Negative NPV: The project would diminish value and should generally be rejected.

For each project:


  • Discount all expected cash flows at 11%

  • Sum these discounted cash flows to determine the NPV


The project with the higher NPV is generally preferred, assuming all other factors are equal.

Understanding Internal Rate of Return (IRR)

IRR is the discount rate at which the NPV equals zero. It indicates the expected rate of return from the project:
    • If IRR > WACC (11%), the project is likely profitable.
    • If IRR < WACC, the project may destroy value.

However, IRR should not be the sole criterion, especially when comparing mutually exclusive projects, due to potential conflicts with NPV and scale differences.

Making the Decision: Comparing Two Projects

Given two mutually exclusive projects, the choice hinges on a comprehensive comparison of their financial metrics and qualitative factors.

Step-by-Step Approach

    • Estimate Cash Flows: Forecast the expected cash inflows and outflows for each project.
    • Calculate NPVs: Discount the cash flows at 11% for each project to find their NPVs.
    • Determine IRRs: Compute the IRRs for each project for additional insight.
    • Compare NPVs and IRRs: Select the project with the higher NPV, provided the IRR exceeds WACC.
    • Assess Qualitative Factors: Consider strategic alignment, risk profile, resource availability, and market conditions.

Note: Since the projects are mutually exclusive, choosing the project with the higher NPV generally maximizes shareholder wealth.

Considering Risks and Strategic Fit

While financial metrics are central, qualitative factors are equally important in decision-making.

Risk Analysis

  • Project-specific risks: Market volatility, technological uncertainties, regulatory changes.
  • Financial risks: Changes in interest rates, capital availability.
  • Mitigation strategies: Diversification, hedging, contingency planning.

Strategic Alignment

  • Does the project support long-term strategic goals?
  • Will it enhance the company's competitive position?
  • Is the project aligned with core competencies?
Incorporating these considerations ensures that the selected project not only provides financial gains but also supports sustained growth.

Implications of an 11% WACC in Investment Decision-Making

An 11% WACC indicates the company's cost of capital, reflecting its risk appetite and market conditions. When evaluating projects:


  • Projects with expected returns above 11%: Are considered value-adding, as they surpass the company's hurdle rate.

  • Projects with returns close to 11%: Require careful analysis, as the risk-adjusted return may be marginal.

  • Projects with returns below 11%: Should typically be rejected unless strategic benefits outweigh financial concerns.


In cases where both projects exceed the WACC, the decision comes down to which provides the greater incremental value.

Real-World Application: A Hypothetical Scenario

Suppose the company is evaluating two projects:


  • Project A:

  • Initial investment: $10 million

  • Expected cash flows over 5 years: $3 million annually

  • Calculated NPV at 11%: $2 million

  • IRR: 15%

  • Project B:

  • Initial investment: $8 million

  • Expected cash flows over 5 years: $2.5 million annually

  • Calculated NPV at 11%: $1.8 million

  • IRR: 14%


Both projects have IRRs above the WACC, but Project A has a higher NPV, making it the preferable choice, assuming strategic fit and risk profiles align.

Key takeaway: Even when both projects are profitable, the one with the higher NPV maximizes shareholder value.

Conclusion: Making the Optimal Investment Choice

Choosing between two mutually exclusive projects when a company has an 11% WACC involves a detailed financial and strategic analysis. The primary goal is to select the project that adds the most value—typically the one with the higher NPV—while ensuring that the expected returns exceed the company's cost of capital. Incorporating qualitative factors such as risk, strategic fit, and market conditions further refines the decision.

Ultimately, a disciplined approach—estimating cash flows accurately, calculating NPVs and IRRs, and aligning with strategic objectives—enables companies to make informed investment decisions that enhance shareholder wealth. In scenarios with mutually exclusive projects, the one that best surpasses the 11% hurdle rate and aligns with the company's long-term plans should be prioritized, ensuring sustainable growth and value creation.

Additional Tips for Investors and Managers:


  • Regularly reassess the WACC, as it can fluctuate with market conditions.

  • Use scenario analysis to understand how changes in assumptions impact project viability.

  • Consider non-financial benefits that may not be immediately quantifiable but are strategically important.


By applying these principles diligently, companies can navigate complex investment choices confidently, leveraging their understanding of WACC and project evaluation metrics to maximize value.

Frequently Asked Questions

The 11% WACC represents the company's average cost of capital, serving as the minimum required return for any investment; investments should ideally generate returns above this rate to add value.
How do mutually exclusive investments impact decision-making when using WACC?
When investments are mutually exclusive, the company must compare their respective returns to the WACC to determine which project offers the higher net value, as only one can be accepted.
What methods can be used to evaluate which of the two investments is more favorable given the 11% WACC?
Methods such as Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period analysis can be used, with preference for projects whose IRR exceeds the WACC or that have higher NPV values.
If both investments have IRRs above 11%, how should the company decide which to pursue?
The company should choose the investment with the higher NPV or IRR, considering strategic fit, risk profile, and potential for growth, since both exceed the WACC.
How does the 11% WACC influence the risk assessment of the two investments?
A WACC of 11% provides a benchmark for acceptable risk-adjusted returns; investments requiring returns above this threshold are considered to have acceptable risk-adjusted profitability.
What are potential pitfalls of relying solely on WACC when choosing between these two investments?
Relying solely on WACC can overlook qualitative factors, project-specific risks, and strategic considerations; it’s essential to incorporate other analysis methods and judgment.
Why can't the investments be repeated, and how does this affect the capital budgeting process?
The investments are mutually exclusive and cannot be repeated, meaning the company must select only one, making capital allocation more critical and requiring careful comparison of their profitability metrics.
