Cash Offer vs Share Exchange in Acquisitions

Updated 11 October 2026 · Fact-checked

A cash offer pays target shareholders money, usually raised from debt or a rights issue. A share exchange gives them acquirer shares. To choose, compare the effect on EPS, gearing, tax and control, and on who bears the risk of synergies. Calculate each option's post-deal figures, then recommend with reasons.

Understand Methods of Financing Acquisitions: Cash vs Share Exchange

When a company buys another, it must pay the target's shareholders. There are three routes: cash, shares (a share-for-share exchange), or a mixed offer with both. The headline price can be identical in all three. What changes is who carries the risk, who owns the combined company, and how the deal affects the acquirer's financial position.

In a cash offer, target shareholders leave with a fixed sum. They take no further risk and get no share of future synergies. They may face an immediate tax charge on their gain. The acquirer must find the cash, usually by new debt, a rights issue or existing cash. Debt raises gearing and interest cost, but interest is normally tax-deductible. A rights issue protects gearing but needs shareholder support and takes time.

In a share exchange, target shareholders become shareholders in the enlarged company. They share in the synergies, and also in the risk that the synergies never arrive. The acquirer needs no cash, and gearing usually falls or stays steady. But its existing shareholders are diluted, so control is shared. The value of the offer moves with the acquirer's share price, so the target may see the offer value change before it closes. In many tax systems, a share exchange can defer the target holders' tax charge. Always use the tax information the exam gives you.

A useful rule of thumb on cost: a cash offer funded by debt is often cheaper for the acquirer when the after-tax cost of debt is below the acquirer's earnings yield (1 ÷ P/E). This is a guide, not a law. It ignores the extra financial risk that debt brings.

The exam rarely asks only for a calculation. You must compute EPS, gearing and ownership under each option, then advise. Your advice should cover the acquirer's shareholders, the target's shareholders and any other stakeholders.

Key rules to remember

Offer value per target share (cash): Offer value = cash per share × number of target shares; Total cash needed. Add any transaction costs if the question gives them.
Offer value per target share (share exchange): Value per target share = exchange ratio × acquirer share price; For example, 1 for 2 means 0.5 acquirer shares per target share. Use the acquirer's price before the bid unless told otherwise.
New shares issued: New shares = target shares × exchange ratio; Add to the acquirer's existing shares to get the enlarged share count.
After-tax cost of new debt: Interest after tax = debt raised × interest rate × (1 − tax rate); Deduct from combined earnings in a cash offer funded by debt.
Post-deal EPS: EPS = (acquirer earnings + target earnings + after-tax synergies − after-tax interest on new debt) ÷ (existing shares + new shares); Use only the items that apply to the option you are testing.
Ownership split: Target holders' share = new shares ÷ (existing shares + new shares); Shows dilution and the loss of control for the acquirer's shareholders.
Gearing (market value basis): Gearing = debt ÷ equity, or debt ÷ (debt + equity), using market values; State which definition you use. Say what you assume about the share price after the deal.
Post-merger share price (value approach): Price = (value of acquirer + value of target + PV of synergies − cash paid) ÷ total shares after the deal; Use it to compare what each group of shareholders gains under each offer.
Earnings yield test: Earnings yield = 1 ÷ P/E = EPS ÷ share price; Compare with the after-tax cost of debt as a quick guide to which method boosts EPS.

How to solve Methods of Financing Acquisitions: Cash vs Share Exchange questions

Use this order for any question that asks you to compare cash, share and mixed offers. It keeps your numbers and your advice in step.

1Read the requirement and note which parties you must advise: acquirer shareholders, target shareholders, or both.
2Fix the offer value. Work out the price per target share and the total consideration for each option, including the exchange ratio.
3Work out the funding. For cash, find the amount to raise and the source (debt, rights issue or existing cash). For shares, find the number of new shares issued.
4Calculate combined earnings for each option. Include synergies if given, and deduct after-tax interest on any new debt.
5Compute EPS, ownership split and gearing for each option. State your assumptions, such as an unchanged share price or market-value gearing.
6Compare against the starting position: acquirer EPS before the deal, gearing before the deal and current control.
7Add the qualitative factors: tax position of target holders, risk and synergy sharing, control, debt covenants and capacity, market reaction and speed of execution.
8Make a clear recommendation, say who it suits, and note a risk or limit on your numbers.

Quickest way: Table-in-your-head comparison

When to use it: Use it when time is short and the question gives EPS, shares in issue, price and a funding rate for each company.

Write three columns: Cash, Shares, Mixed. Fill in the new debt and the new shares for each.
Find after-tax interest in one line: debt × rate × (1 − tax).
Add the two earnings figures, subtract interest, and divide by the share count. That gives EPS for each column.
Compute ownership as new shares ÷ total shares, and gearing as debt ÷ equity for each column.
Spend the last third of your time on the written advice: tax, risk, control and a firm recommendation.

Common mistakes in Methods of Financing Acquisitions: Cash vs Share Exchange

Deducting interest before tax, or forgetting to deduct it at all in a debt-funded cash offer.
Students focus on the extra earnings of the target and forget the funding cost.
Fix: Always write 'interest × (1 − tax)' as its own line. Deduct it from combined earnings before dividing by shares.
Adding new shares in a cash offer, or ignoring new shares in a share exchange.
Students mix up what each method issues.
Fix: Cash funded by debt issues no shares. Share exchange issues shares equal to target shares × exchange ratio. Check this before computing EPS.
Using the target's share price to set the share-exchange ratio instead of the offer price.
The premium is forgotten.
Fix: First compute the offer price per target share, including the premium. Then divide by the acquirer's price to get the ratio.
Saying a share exchange is always better because it avoids debt.
Students treat gearing as the only factor.
Fix: Weigh dilution, shared synergies, share price risk and control as well. Debt can be cheaper after tax and keeps the acquirer's shareholders in full control.
Recommending a method on EPS alone.
EPS is easy to compute and looks decisive.
Fix: EPS ignores risk. A higher EPS from debt comes with higher financial risk. Comment on value, risk, tax and control before concluding.
Leaving out the target shareholders' viewpoint.
Students assume the acquirer is the client.
Fix: Say what each method means for the target holders: certainty and possible immediate tax with cash, versus risk, sharing in synergies and possible tax deferral with shares.

Worked examples

Example 1

Alpha has 10m shares at $5.00 and EPS of $0.40. Target has 4m shares at $4.00 and EPS of $0.50. Alpha offers $5.00 per Target share, either in cash (funded by new 8% debt) or by issuing 1 Alpha share for each Target share. Tax is 25%. Ignore synergies and costs. Calculate Alpha's post-deal EPS under each option and advise which gives the higher EPS.

Show the solution

Alpha earnings = 10m × $0.40 = $4.0m. Target earnings = 4m × $0.50 = $2.0m.
Cash option: consideration = 4m × $5.00 = $20m, raised as new debt.
After-tax interest = $20m × 8% × (1 − 0.25) = $1.2m.
Combined earnings = $4.0m + $2.0m − $1.2m = $4.8m. Shares remain 10m. EPS = $4.8m ÷ 10m = $0.48.
Share option: the exchange value is 1 × $5.00 = $5.00 per Target share, equal to the cash offer. New shares = 4m × 1 = 4m.
Combined earnings = $4.0m + $2.0m = $6.0m. Shares = 10m + 4m = 14m. EPS = $6.0m ÷ 14m = $0.4286, about $0.43.
Check: Alpha's earnings yield is $0.40 ÷ $5.00 = 8%. After-tax cost of debt is 8% × 0.75 = 6%. Debt is cheaper than equity on this basis, so cash gives the higher EPS.

Answer: EPS is $0.48 with the cash offer and about $0.43 with the share exchange. Both beat the current $0.40, but cash gives the higher EPS because the after-tax cost of debt (6%) is below Alpha's earnings yield (8%). The cash offer also raises financial risk, which EPS does not show.

Example 2

Using the same companies, Alpha considers a mixed offer: for every 2 Target shares, Target holders get 1 Alpha share plus $5.00 in cash (worth $5.00 per Target share in total). The cash is raised by new 8% debt. Alpha already has debt of $20m. Assume Alpha's share price stays at $5.00 and tax is 25%. Calculate EPS, Target holders' ownership and market-value gearing (debt ÷ equity), and compare with the all-cash and all-share options.

Show the solution

Value check: per 2 Target shares, 1 × $5.00 + $5.00 = $10.00, which is $5.00 per share. Total value = $20m.
Cash paid = 4m ÷ 2 × $5.00 = $10m. New shares = 4m ÷ 2 × 1 = 2m.
After-tax interest = $10m × 8% × 0.75 = $0.6m.
Combined earnings = $4.0m + $2.0m − $0.6m = $5.4m. Shares = 10m + 2m = 12m. EPS = $5.4m ÷ 12m = $0.45.
Target holders' ownership = 2m ÷ 12m = 16.7%.
Gearing: debt = $20m + $10m = $30m. Equity at $5.00 = 12m × $5.00 = $60m. Debt ÷ equity = 30 ÷ 60 = 50%.
Comparison, all-cash: debt $40m, equity $50m, gearing 80%. All-share: debt $20m, equity 14m × $5.00 = $70m, gearing about 28.6%.
Starting gearing = $20m ÷ $50m = 40%.

Answer: The mixed offer gives EPS of $0.45, Target holders own 16.7% and gearing is 50%. This sits between the all-cash option (EPS $0.48, gearing 80%, no Target ownership) and the all-share option (EPS about $0.43, gearing about 28.6%, Target ownership about 28.6%). The mixed offer balances EPS, risk and control. Target holders also get some certainty from the cash and some share in the synergies.

Exam tips

Show a short comparison of each option on EPS, gearing and ownership. Then spend the remaining time on advice. Professional skills marks reward a clear, reasoned recommendation.
State your assumptions, such as share price unchanged after the bid or gearing on a market-value basis. Markers give credit for stated, sensible assumptions.
Apply the answer to the scenario. Use the company's tax position, debt covenants, shareholder base and the target's likely preferences, not generic points.
Advise both sides when the requirement allows. For example, explain what a target board might prefer and why.
If a rights issue or convertible is offered as funding, say how it changes gearing, dilution and timing compared with debt.

Methods of Financing Acquisitions: Cash vs Share Exchange: frequently asked questions

What is the main difference between a cash offer and a share-for-share offer?

In a cash offer, target shareholders receive money and leave the company. In a share exchange, they receive acquirer shares and stay as owners of the combined company. This changes risk, tax, control and the acquirer's gearing.

Which method is usually better for EPS in AFM questions?

It depends on the numbers. If the after-tax cost of debt is lower than the acquirer's earnings yield, a debt-funded cash offer tends to give higher EPS. If it is higher, a share exchange tends to do better. Always compute both and also comment on risk.

Why might target shareholders prefer shares to cash?

Shares let them share in the synergies and may defer tax on their gain in many tax systems. Cash gives certainty but may trigger an immediate tax charge. The best choice depends on their tax position and views on the combined company.

How do I decide between cash, shares and a mixed offer in the exam?

Calculate EPS, gearing and ownership for each, then consider tax, control, risk and how the market might react. Recommend the option that best fits the acquirer's capacity and aims, and say what you assumed. A mixed offer is often a sensible compromise.
