Impact of Acquisition on Acquirer: EPS, Share Price and Gearing

Updated 11 October 2026 · Fact-checked

The impact of an acquisition on the acquirer is found by building combined earnings and shares, then calculating post-deal EPS, share price and gearing. Split the value created between bidder and target shareholders. The maximum price is the target's standalone value plus synergies. Cash adds debt; shares dilute ownership and EPS.

Understand Impact of Acquisition on Acquirer: EPS, Share Price and Gearing

A bid changes three things for the acquirer: its earnings per share (EPS), the value of its shares, and its financing mix. AFM questions ask you to measure each one and then advise the board.

Start with value. A target is worth its standalone value to the bidder. The bidder can pay more only because of synergies, such as cost savings or higher revenue. So the maximum price is the target's standalone value plus the present value of synergies. Pay less than that and the bidder gains. Pay exactly that and the bidder gains nothing. The premium is the price paid minus the target's current market value. It is the part of the synergy that the bidder hands to the target's shareholders.

Next, the form of payment. In a cash offer, target shareholders are paid out and leave. The bidder funds the cash with debt or a rights issue, so gearing may rise. In a share offer, target shareholders become shareholders of the bidder. They share in the combined company, including its synergies and its risk. The bidder issues new shares, so EPS is diluted unless the earnings acquired are large enough.

EPS is easy to compute but can mislead. EPS can rise just because the bidder has a higher P/E ratio than the target. It buys low-multiple earnings with high-multiple shares. A rise in EPS does not prove value was created. The market may not keep the bidder's P/E after the deal. So the better test is the change in total shareholder wealth, which is the gain to each party.

Finally, gearing. Compare debt to equity (or debt to debt plus equity) before and after the deal, using market values where the question gives them. Include any target debt taken over and any new borrowing for the cash payment. Then comment on covenants, interest cover and risk.

Key rules to remember

Post-deal EPS: Combined EPS = (Bidder earnings + Target earnings + post-tax synergies − extra post-tax finance cost) ÷ (Bidder shares + new shares issued); Use the same earnings basis for both companies. Synergies and finance costs must be after tax.
New shares issued in a share offer: New shares = Target shares × exchange ratio; Exchange ratio = bidder shares offered per target share, for example 2 for 3 is 0.667.
Share price from P/E: Share price = EPS × P/E ratio; State which P/E you assume after the deal. Often the bidder's existing P/E is used.
Maximum price the bidder can pay: Maximum price = Target standalone value + PV of synergies; Divide by target shares for a maximum price per share.
Premium: Premium = Offer price − Target's current market price; The premium is the target's gain in a cash offer.
Gain to each party: Total gain = Combined value after deal − (Bidder value + Target value before). Bidder gain = Total gain − Target gain; In a cash offer, target gain = premium × number of shares. In a share offer, target gain = value of its share of the combined company − its old value.
Gearing: Debt ÷ Equity, or Debt ÷ (Debt + Equity); Say which measure you use. Use market values if given, otherwise book values.

How to solve Impact of Acquisition on Acquirer: EPS, Share Price and Gearing questions

Use this order for any question on the effect of a takeover on the bidder. Keep each party's figures in separate lines so you can show every step.

1List the facts for bidder and target: shares, earnings, EPS, P/E, share price, debt and market value of equity. Mark which numbers are given and which you must work out.
2Fix the offer terms. For a share offer, calculate the new shares issued. For a cash offer, calculate the total cost and how it is funded.
3Build the combined earnings: both companies' earnings plus post-tax synergies, less post-tax interest on any new debt or lost interest on cash used.
4Calculate post-deal EPS and compare with the bidder's EPS before the deal. State the percentage change.
5Estimate the new share price or combined value using a stated P/E or a stated value of synergies. Say that this is an assumption.
6Work out the gain to each party. For a share offer, split the combined value by ownership. For a cash offer, the target gets the premium and the bidder keeps the rest of the NPV.
7Recalculate gearing after the deal, including target debt taken over and any new borrowing.
8Conclude and advise. Say whether the deal creates value, whether the target would accept, which financing is better and what risks remain. Add professional skills points: scepticism about synergy estimates and a clear recommendation.

Quickest way: Value-first shortcut

When to use it: Use when time is short, or when the question asks only for maximum price or gain to each party.

Write: Maximum price = target value + PV of synergies. Divide by target shares.
Compare the offer with the target's market value. The difference is the target's gain in a cash offer.
Bidder gain = PV of synergies − premium paid, for a cash offer.
For a share offer, find combined value, multiply by each side's ownership share, and subtract the old values.
Check that the two gains add up to the total value created. If not, find the slip before moving on.
For gearing, add new debt and target debt to existing debt and divide by the new equity value. Leave the full EPS table for last.

Common mistakes in Impact of Acquisition on Acquirer: EPS, Share Price and Gearing

Treating a higher EPS as proof that shareholders gain.
EPS is easy to calculate and looks decisive. The bidder's higher P/E can lift EPS with no real value created.
Fix: Always follow EPS with a value test: combined value after the deal against the sum of the old values. Comment on whether the P/E is sustainable.
Forgetting that new shares are issued to target holders, or calculating them from the wrong share count.
Students mix up the exchange ratio direction and use bidder shares instead of target shares.
Fix: Write: new shares = target shares × bidder shares offered per target share. Check the result against the offer wording.
Adding pre-tax synergies or interest to post-tax earnings.
The question gives pre-tax figures and the tax step is skipped.
Fix: Convert synergies and finance costs to after-tax amounts before adding them to earnings.
Paying the target's whole gain in the maximum price, then claiming the bidder still gains.
Students confuse the maximum price with a sensible offer price.
Fix: The maximum price leaves the bidder with zero gain. A sensible offer is below it. Show the bidder's gain as synergies minus premium.
Leaving out the target's existing debt when measuring gearing after a deal.
Attention is on the new borrowing for the cash price.
Fix: Add the target's debt that stays in the combined group, plus any new debt, to the bidder's own debt.
Giving no recommendation, or ignoring risk in a share offer.
Students stop once the numbers are done.
Fix: End with a clear view. Cover dilution of control, target holders sharing in synergies, risk of overpaying and effect on covenants.

Worked examples

Example 1

Alpha has 10 million shares at $24 each, earnings of $20 million and a P/E of 12. Beta has 3 million shares at $15 each, earnings of $4.5 million and a P/E of 10. Alpha offers 2 of its shares for every 3 Beta shares. Post-tax synergies of $1.5 million a year are expected, and the market is assumed to apply Alpha's P/E of 12 to the combined earnings. Calculate post-deal EPS, the share price and the gain to each group of shareholders.

Show the solution

Alpha's EPS before the deal = $20m ÷ 10m = $2.00. Beta's market value = 3m × $15 = $45m. Alpha's market value = 10m × $24 = $240m.
New Alpha shares = 3m × 2/3 = 2 million. Total shares = 12 million.
Combined earnings = $20m + $4.5m + $1.5m = $26.0m.
Post-deal EPS = $26.0m ÷ 12m = $2.1667, about $2.17. This is 8.3% above $2.00.
Share price = $2.1667 × 12 = $26.00. Combined value = 12m × $26 = $312m.
Beta holders own 2m ÷ 12m = 1/6 of the group = $52m. Their old value was $45m, so their gain is $7m. Per Beta share they receive 2/3 × $26 = $17.33 against $15.
Alpha holders own 5/6 = $260m against $240m before. Gain = $20m.
Check: total gain = $312m − ($240m + $45m) = $27m = $20m + $7m. It is made of synergies at P/E 12 ($1.5m × 12 = $18m) and the re-rating of Beta's earnings ($4.5m × (12 − 10) = $9m).
Comment: most of the gain depends on Alpha's P/E holding. If the market applies a lower blended P/E, the gains shrink and Alpha holders could lose.

Answer: Post-deal EPS is about $2.17 (up 8.3%), the share price is $26.00, Alpha shareholders gain $20 million and Beta shareholders gain $7 million. The result depends on the P/E of 12 being kept.

Example 2

Delta has debt of $30 million and equity with a market value of $90 million. It plans to buy Zeta, which has 5 million shares at $4.00 each, for cash. The present value of synergies is $6 million. Zeta's debt of $5 million will stay in the group. Delta will borrow all of the cash price. (a) Calculate the maximum price per share Delta could pay. (b) Delta offers $4.80 per share. Calculate the gains to each party and Delta's gearing (debt ÷ equity at market values) before and after the deal, assuming the market values Delta's equity at the old value plus Delta's gain.

Show the solution

(a) Zeta's market value = 5m × $4.00 = $20m. Maximum price = $20m + $6m = $26m. Per share = $26m ÷ 5m = $5.20, a 30% premium over $4.00.
(b) Cost at $4.80 = 5m × $4.80 = $24m. Premium paid = ($4.80 − $4.00) × 5m = $4m.
Gain to Zeta shareholders = $4m.
Gain to Delta shareholders = synergies − premium = $6m − $4m = $2m. Total gain = $6m, which equals the synergies.
Gearing before = $30m ÷ $90m = 33.3%.
Debt after = $30m + $5m (Zeta's debt) + $24m (new borrowing) = $59m.
Equity value after = $90m + $2m = $92m.
Gearing after = $59m ÷ $92m = 64.1%.
Comment: gearing almost doubles. Delta should check interest cover and covenants. A part-share offer or a rights issue could lower the risk.

Answer: (a) The maximum price is $5.20 per share. (b) Zeta holders gain $4 million and Delta holders gain $2 million. Delta's gearing rises from 33.3% to 64.1%.

Exam tips

Show the gain to each party even when the requirement only says 'evaluate'. Markers expect the split of value, not just EPS.
State every assumption about the P/E or share price after the deal. Marks are given for assumptions that are clear and sensible.
Always add a discussion to your numbers: dilution, control, risk of overpaying, effect on gearing and the reliability of synergy estimates. These earn technical and professional skills marks.
For cash against share offers, compare both on the same page: who bears the risk, who gets the synergies, and the effect on EPS and gearing.
Keep to the question's currency and rounding. Label each number so a marker can follow your working and give method marks even if one figure is wrong.

Practice questions from Valuation for acquisitions and mergers

Impact of Acquisition on Acquirer: EPS, Share Price and Gearing: frequently asked questions

How do I calculate the maximum price a bidder can pay for a target?

Add the target's standalone value to the present value of synergies, then divide by the number of target shares if you need a price per share. At this price the bidder's gain is zero. A sensible offer is lower, so that some of the synergy stays with the bidder's shareholders.

How do I calculate the gain to shareholders in an acquisition?

Find the total value created, which is the combined value after the deal less the two separate values before. In a cash offer, the target's gain is the premium and the bidder keeps the rest. In a share offer, split the combined value by ownership and subtract each party's old value.

Is a cash offer or a share offer better for the bidder?

Neither is always better. A cash offer keeps the bidder's ownership but adds debt and gives all of the risk to the bidder. A share offer protects the bidder's gearing and shares the risk and synergies with target holders, but it dilutes ownership and EPS.

Why can EPS rise even if the deal does not create value?

If the bidder's P/E is higher than the target's, it can issue shares priced at a high multiple to buy earnings priced at a low multiple. EPS then rises on paper. The gain is real only if the market keeps the bidder's P/E for the larger group.
