Guidance: How to use this card
- Read "The idea in plain language" first, then rebuild Worked example A in a spreadsheet before you read its tables.
- Keep three things apart in every model: the operating earnings of both firms, the deal effects (financing,
  amortisation, synergies, one-off costs) and the share count. Most errors come from mixing them.
- Always report accretion together with value (mba/mba-synergy-valuation-card), leverage and ownership. A merger model
  that shows only EPS invites the wrong decision.
- Every number was computed in Python; Excel formulas are shown next to results.

## When to use it

<!-- Guidance: Use this card when someone asks "is it accretive?". Use the synergy card when someone asks "is it worth it?". You usually need both. -->

| Use it when | Use something else when |
|---|---|
| A listed acquirer must show investors how a deal changes EPS in the first two or three years | You need to decide whether the deal creates value (mba/mba-synergy-valuation-card, mba/mba-dcf-valuation-card) |
| You compare cash, stock and mixed consideration | The buyer is a financial sponsor; use returns, not EPS (mba/mba-lbo-model-card) |
| You need the synergies required to avoid dilution, or the highest EPS-neutral price | The target is a private start-up bought for technology; EPS effects are noise next to strategy |
| You prepare for a banking or corporate development interview | You need detailed structuring of earn-outs or collars (mba/mba-deal-structuring-card) |

## The idea in plain language

<!-- Guidance: Say the idea in one sentence before any formula: the buyer gains the target's earnings and pays for them with currencies that each have an earnings cost. -->

When a company buys another, it adds the target's earnings to its own, but it pays with something that also has an
earnings cost. Paying in **new shares** spreads the combined earnings over more shares; the cost of each share is the
acquirer's earnings yield (the inverse of its P/E). Paying in **new debt** adds interest, reduced by the tax shield.
Paying with **cash on hand** gives up the interest that cash was earning, also after tax. The deal is accretive when
the earnings bought (the target's earnings yield at the offer price) exceed the weighted earnings cost of the
currencies used. The quick test in mba/mba-banking-technical-prep does exactly this.

A full merger model adds four layers the quick test ignores:

1. **Purchase price allocation.** Under the acquisition method (IFRS 3; ASC 805), the target's identifiable assets
   are remeasured at fair value. Acquired intangible assets with finite lives (customer relationships, technology,
   brands with a finite life) are amortised, which lowers reported earnings every year. Goodwill is not amortised under
   IFRS (it is tested for impairment under IAS 36) nor, for public companies, under US GAAP (ASC 350); US private
   companies may elect a goodwill amortisation alternative (check the FASB Codification). Many acquirers also report an adjusted or "cash" EPS that adds back acquired
   amortisation, so state which EPS you show.
2. **Deal costs and financing fees.** Advisory, legal and valuation costs are expensed when incurred (IFRS 3
   paragraph 53; ASC 805) and are usually excluded from forward EPS; they still have to be paid, from cash or debt.
   The exception is the cost of issuing securities: debt issue costs reduce the carrying amount of the debt and are
   spread over its life through the effective interest rate (IFRS 9), and equity issue costs are deducted from equity
   (IAS 32). This card treats the USD 25m of deal costs in example A as advisory costs.
3. **Synergies and costs to achieve.** Cost synergies phase in over one to three years; revenue synergies are often
   excluded from the EPS case because analysts discount them; one-off costs to achieve depress reported earnings in
   the first years.
4. **Timing and share count.** EPS under IAS 33 uses the weighted average number of ordinary shares during the period,
   so shares issued at a mid-year closing count only for the months they are outstanding.

The deeper lesson is that EPS is an accounting ratio, not a measure of value. A cash deal funded with cheap debt is
almost always accretive, even if the buyer overpays, because the after-tax interest rate is lower than most earnings
yields. A stock deal by a low-P/E buyer is dilutive even if it creates value. Boards still care about accretion
because markets, rating agencies and compensation plans watch EPS, so the right use of this card is as a
**constraint and communication tool** alongside value, leverage and risk sharing.

## Formulas and notation

<!-- Guidance: Write the formula with every deal effect as a separate term. When a number surprises you, you can then see which term caused it. -->

**Pro forma EPS** (deal closes at the start of the year; amounts for year $y$):

$$
EPS_{PF,y} = \frac{NI_{A,y} + NI_{T,y} + \left(S_y - C_y - Am - r_D D - r_C K\right)(1 - t)}{N_A + N_{new}}
$$

**New shares, cash and debt** for a share $\alpha$ of the price $P$ paid in stock and deal costs $F$:

$$
N_{new} = \frac{\alpha P}{P_A}, \qquad K = \min\left(K_0, (1-\alpha) P + F\right), \qquad D = (1-\alpha) P + F - K
$$

**Accretion or dilution:**

$$
\text{Accretion}_y = \frac{EPS_{PF,y}}{EPS_{A,y}} - 1, \qquad EPS_{A,y} = \frac{NI_{A,y}}{N_A}
$$

**Quick test** (no synergies, amortisation or fees; all stock or all debt):

$$
\text{All stock accretive} \iff \frac{P_A}{EPS_A} > \frac{P}{NI_T}, \qquad \text{All debt accretive} \iff r_D (1-t) < \frac{NI_T}{P}
$$

**Break-even pre-tax synergies** (synergies that make the deal EPS-neutral in year $y$), where $NI_{PF,y}^{0}$ is
pro forma net income without synergies:

$$
S_y^{*} = \frac{EPS_{A,y} (N_A + N_{new}) - NI_{PF,y}^{0}}{1 - t}
$$

**Ownership, contribution and leverage:**

$$
\omega_T = \frac{N_{new}}{N_A + N_{new}}, \qquad c_T = \frac{NI_T}{NI_A + NI_T}, \qquad L = \frac{ND_A + ND_T + D + K}{EBITDA_A + EBITDA_T + S}
$$

Cash on hand used ($K$) raises net debt just as new debt ($D$) does, because net debt is debt minus cash.

| Symbol | Meaning | Unit |
|---|---|---|
| $NI_{A,y}$, $NI_{T,y}$ | Standalone net income of acquirer and target in year $y$ | USD m |
| $S_y$ | Pre-tax synergies included in the EPS case in year $y$ (net of dis-synergies) | USD m |
| $C_y$ | Pre-tax one-off costs to achieve synergies (zero in an adjusted EPS case) | USD m |
| $Am$ | Pre-tax amortisation of acquired intangible assets | USD m per year |
| $r_D$, $r_C$ | Pre-tax interest rate on new debt; pre-tax interest forgone on cash on hand | % |
| $D$, $K$, $K_0$ | New debt; cash on hand used; cash on hand available | USD m |
| $P$, $F$ | Equity purchase price; deal costs | USD m |
| $\alpha$ | Share of the price paid in acquirer stock | 0 to 1 |
| $P_A$ | Acquirer share price at which new shares are issued | USD |
| $N_A$, $N_{new}$ | Acquirer shares before the deal; new shares issued | m |
| $t$ | Tax rate | % |
| $\omega_T$, $c_T$ | Target holders' ownership of the combined firm; target's contribution to combined net income | % |
| $L$ | Pro forma net debt to EBITDA | x |

## Assumptions and limits

<!-- Guidance: Put these in the limitations paragraph of a case answer. The first two are the ones faculty test. -->

- **EPS ignores the cost of risk.** Debt-funded accretion comes with higher leverage, a higher cost of equity and
  possible rating pressure (mba/mba-capital-structure-card). Two deals with the same accretion can differ greatly in
  value.
- **EPS ignores the premium relative to synergies.** A deal can be accretive and still transfer more value to the
  target's shareholders than the synergies create.
- **The issue price is not fixed.** New shares are modelled at the current price, but announcement reactions (often
  negative for stock-financed bids, Travlos 1987) and fixed or floating exchange ratios change the real cost.
- **Analysts' EPS is a choice.** Adjusted EPS excludes costs to achieve and sometimes amortisation; reported EPS under
  IAS 33 includes them. Always show both.
- **Standalone forecasts are contestable.** Accretion depends on both firms' forecasts; a target with an optimistic
  plan makes any deal look accretive.
- **The model is static.** Debt paydown, share buy-backs, refinancing of the target's debt and changes in tax rates
  move the numbers in years 2 and 3. This card holds debt constant to keep the mechanics visible.
- **Purchase price allocation is an estimate.** Fair values and useful lives are set after closing with valuation
  specialists; early models use ranges.

## How managers use it in practice

<!-- Guidance: Follow the steps in order. A team that starts by tuning the payment mix to hit "accretive in year 1" has reversed the logic. -->

1. **Value first.** Decide the walk-away price from standalone value and net synergies (mba/mba-synergy-valuation-card).
2. **Build the standalone forecasts** of both companies on consistent accounting and calendar years.
3. **Lay out sources and uses**: price, refinancing of target debt, fees, against cash on hand, new debt and new stock.
4. **Estimate purchase price allocation**: intangible step-ups, lives, deferred tax, goodwill.
5. **Run EPS for each payment mix** for years 1 to 3, adjusted and reported, with and without synergies.
6. **Check the constraints**: leverage against covenants and rating thresholds, ownership and voting, the need for a
   shareholder vote when many shares are issued (check the listing rules that apply).
7. **Find break-evens**: synergies for EPS neutrality, highest EPS-neutral price, payment mix at which accretion turns
   negative.
8. **Communicate**: lead with value and strategy, then accretion timing and the synergy plan.

## Worked example A (fully solved): Acquirer P and Target Q

<!-- Guidance: Rebuild this in a spreadsheet before reading the tables. Check your year 1 all-cash EPS (1.6396) before going further. -->

**Situation (*Example*, fictional).** Acquirer P, a listed company, agrees to buy Target Q, a listed competitor with no
debt, at a 30% premium. The synergy case comes from mba/mba-synergy-valuation-card (same deal): cost synergies of
USD 30m in year 1 and USD 60m in year 2, net of dis-synergies of USD 6m and USD 12m. Revenue synergies are excluded
from the EPS case, as analysts usually do. Costs to achieve are USD 70m in year 1 and USD 30m in year 2. The deal
closes at the start of year 1.

| *Example* input | Acquirer P | Target Q |
|---|---|---|
| Net income, year 1 / year 2 (USD m) | 400.0 / 420.0 | 90.0 / 94.5 |
| Shares (m) | 250.0 | 60.0 |
| Share price (USD) | 28.00 | 22.50 |
| EBITDA (USD m) | 700.0 | 150.0 |
| Net debt (USD m) | 900.0 | 0.0 |
| Cash on hand available for the deal (USD m) | 200.0, earning 3.0% pre-tax | |

Other inputs: tax rate 25%; new debt at 6.0% pre-tax; deal costs USD 25m paid from cash on hand first; acquired
intangible assets of USD 300m amortised over 10 years (USD 30m a year); new shares issued at USD 28.00.

**Step 1. Price and quick test.**

| Item | Computation | Result | Excel formula |
|---|---|---|---|
| Acquirer EPS, year 1 | 400 / 250 | 1.6000 | `=400/250` |
| Acquirer P/E | 28.00 / 1.60 | 17.50x | `=28/(400/250)` |
| Offer per share | 22.50 x 1.30 | 29.25 | `=22.5*(1+30%)` |
| Equity purchase price | 29.25 x 60 | 1,755.0 | `=29.25*60` |
| P/E paid (year 1) | 1,755 / 90 | 19.50x | `=1755/90` |
| Target earnings yield at offer | 90 / 1,755 | 5.13% | `=90/1755` |
| Cost of stock (acquirer earnings yield) | 1 / 17.5 | 5.71% | `=1/17.5` |
| After-tax cost of new debt | 6.0% x 0.75 | 4.50% | `=6%*(1-25%)` |
| After-tax cost of cash on hand | 3.0% x 0.75 | 2.25% | `=3%*(1-25%)` |

Quick test: stock costs 5.71% but buys 5.13%, so an all-stock deal is dilutive before synergies; debt and cash cost
less than 5.13%, so an all-cash deal is accretive before amortisation and synergies. Without amortisation and
synergies, the full model gives all cash EPS 1.6576 (+3.60%) and all stock 1.5653 (-2.17%).

**Step 2. Sources and uses for three payment mixes.**

| *Example* mix | New shares (m) | Cash on hand used | New debt | Pre-tax financing cost | After-tax financing cost |
|---|---|---|---|---|---|
| All cash ($\alpha$ = 0) | 0.0000 | 200.0 | 1,580.0 | 6.00 + 94.80 = 100.80 | 75.60 |
| Half and half ($\alpha$ = 0.5) | 31.3393 | 200.0 | 702.5 | 6.00 + 42.15 = 48.15 | 36.11 |
| All stock ($\alpha$ = 1) | 62.6786 | 25.0 | 0.0 | 0.75 | 0.56 |

Excel: new shares `=alpha*1755/28`; cash used `=MIN(200,(1-alpha)*1755+25)`; new debt
`=(1-alpha)*1755+25-cash_used`; financing cost `=cash_used*3%+debt*6%`.

**Step 3. Pro forma net income and EPS, all cash, year 1 (adjusted: costs to achieve excluded).**

| Line | USD m | Excel formula |
|---|---|---|
| Acquirer net income | 400.00 | input |
| Target net income | 90.00 | input |
| After-tax financing cost | -75.60 | `=-100.8*(1-25%)` |
| After-tax amortisation | -22.50 | `=-30*(1-25%)` |
| After-tax synergies (24 pre-tax) | 18.00 | `=24*(1-25%)` |
| Pro forma net income | 409.90 | `=SUM(above)` |
| Pro forma EPS | 1.6396 | `=409.9/250` |
| Accretion | +2.47% | `=1.6396/1.6-1` |

**Step 4. All mixes and years (adjusted EPS, amortisation included).**

| *Example* mix and year | EPS without synergies | Accretion | EPS with synergies | Accretion |
|---|---|---|---|---|
| All cash, year 1 | 1.5676 | -2.03% | 1.6396 | +2.47% |
| All cash, year 2 | 1.6656 | -0.86% | 1.8096 | +7.71% |
| Half and half, year 1 | 1.5333 | -4.17% | 1.5973 | -0.17% |
| Half and half, year 2 | 1.6204 | -3.55% | 1.7484 | +4.07% |
| All stock, year 1 | 1.4933 | -6.67% | 1.5509 | -3.07% |
| All stock, year 2 | 1.5717 | -6.45% | 1.6868 | +0.41% |

Standalone EPS is 1.60 in year 1 and 1.68 in year 2. With costs to achieve included (closer to reported EPS), year 1 falls
to 1.4296 (-10.65%) all cash and 1.3830 (-13.56%) all stock, and the USD 25m of advisory deal costs expensed at closing would
lower reported year 1 further: the first reported year after a deal is usually dilutive.

**Step 5. Break-evens.**

| Item | Result | How |
|---|---|---|
| Year 1 pre-tax synergies for EPS neutrality, all stock | 44.46 | $S^{*}$ formula; Excel `=(1.6*312.6786-466.9375)/(1-25%)` |
| Year 1 pre-tax synergies for EPS neutrality, half and half | 25.01 | Same, with 281.3393 shares and 431.3875 income; plan is 24, so slightly dilutive |
| Share of stock at which year 1 accretion turns negative | 46.46% | Goal Seek on $\alpha$ for accretion = 0 |
| Highest offer per share that keeps all stock EPS-neutral in year 2 | 29.84 (32.64% premium) | Goal Seek on the offer for year 2 accretion = 0, holding amortisation at USD 30m |

**Step 6. Constraints.**

| Item | All cash | All stock | Excel formula (all cash) |
|---|---|---|---|
| Pro forma net debt (USD m) | 2,680.0 | 925.0 | `=900+1755+25` |
| Net debt / (EBITDA + year 1 synergies of 24) | 3.07x | 1.06x | `=2680/(700+150+24)` |
| Target holders' ownership | 0.00% | 20.05% | `=62.6786/312.6786` |
| Target contribution to combined net income | 18.37% | 18.37% | `=90/490` |
| Exchange ratio (P shares per Q share) | n/a | 1.0446 | `=29.25/28` |

The acquirer's standalone leverage is 1.29x (`=900/700`). All cash more than doubles it; whether 3.07x is acceptable
depends on covenants and the rating target. In the stock deal, Q's holders get 20.05% of the shares while contributing
18.37% of the net income: a sign that P is paying a premium in shares.

```

Reading the chart: each 10 points of stock replace debt costing 4.50% after tax with shares costing 5.71%, so
accretion falls steadily. The last step, from 90% to 100% stock, is steeper because it replaces cash on hand, the
cheapest currency at 2.25% after tax. Year 2 sits higher because synergies reach their run-rate.

**Conclusion (*Example*).** All cash maximises accretion (+2.47% and +7.71%) but takes leverage to 3.07x. All stock is
dilutive in year 1 (-3.07%) and roughly neutral in year 2 (+0.41%). Half and half is near neutral in year 1 (-0.17%),
accretive in year 2 (+4.07%) and keeps leverage moderate. The choice should follow from value and risk sharing: the
synergy card shows the deal creates value only if most cost synergies arrive, which argues for sharing that risk
with Q's holders through some stock.

## Worked example B (half solved): Acquirer R and Target S

<!-- Guidance: Fill each [ ] before checking the answer key. Work in the same order as example A. -->

**Situation (*Example*, fictional).** Acquirer R (net income USD 150m, 100m shares, price USD 27.00) offers a 35%
premium for Target S (net income USD 30m, 40m shares, price USD 9.00), all in R shares. Tax rate 25%. Ignore fees and
synergies at first.

| Item | Computation | Result |
|---|---|---|
| R EPS and P/E | 150 / 100; 27 / 1.50 | 1.50; 18.0x |
| Offer per share and price | 9.00 x 1.35; x 40 | 12.15; 486.0 |
| P/E paid | 486 / 30 | 16.2x |
| Quick test: accretive or dilutive? | Compare 18.0x with 16.2x | [ ] |
| New shares | 486 / 27 | [ ] |
| Pro forma EPS and accretion | (150 + 30) / (100 + new shares) | [ ] |
| With acquired intangibles amortised at USD 12m a year pre-tax | (150 + 30 - 12 x 0.75) / (100 + new shares) | [ ] |

Question: does amortisation change the sign of the answer? What would you tell R's board?

## Exercise C (unsolved)

<!-- Guidance: Build this one from a blank sheet, then compare with a classmate. No answer key: defend your numbers. -->

Acquirer U (net income USD 900m, 300m shares, price USD 45.00, net debt USD 1,200m, EBITDA USD 1,500m) wants to buy
Target V (net income USD 120m, 80m shares, price USD 20.00, no debt, EBITDA USD 220m) at a 40% premium. Consideration
60% cash (new debt at 5.5% pre-tax) and 40% U shares. Deal costs USD 30m from new debt. Intangible step-up USD 400m
over 8 years. Run-rate cost synergies USD 50m pre-tax, 40% in year 1 and 100% from year 2; costs to achieve USD 60m in
year 1. Tax 25%. Net income of both grows 5% a year.

1. Compute adjusted and reported EPS accretion for years 1 and 2.
2. Find the year 1 break-even synergies and the share of stock at which year 2 accretion is zero.
3. Compute pro forma leverage and V holders' ownership.
4. Write a three-sentence board message that starts with value, not EPS.

## Common mistakes and misconceptions

<!-- Guidance: Check your model against this list before you send it. Items 1, 3 and 6 are the most common in interviews and exams. -->

1. **"Accretive means good."** Accretion says nothing about the premium relative to synergies or the risk added.
2. **Pre-tax interest.** Interest must be taken after tax; using pre-tax interest makes every cash deal look worse.
3. **Forgetting the cost of cash on hand.** Cash used to pay was earning interest; that income disappears.
4. **Leaving out amortisation of acquired intangibles** in reported EPS, or including it without saying so in adjusted
   EPS.
5. **Full run-rate synergies in year 1.** Phase-in and costs to achieve make year 1 the weakest year.
6. **Wrong share count.** New shares must be computed at the acquirer's price, and only for the period outstanding
   (IAS 33 weighted average) if the deal closes mid-year.
7. **Ignoring the target's existing debt.** If it is refinanced, its interest is replaced by acquisition debt
   interest; if it is assumed, its interest stays in the target's net income.
8. **Using P/E on different earnings definitions** (trailing versus forward, adjusted versus reported) in the quick
   test.
9. **Treating the issue price as fixed.** A share price drop after announcement raises the number of shares under a
   fixed-value offer.

## Self-test questions

<!-- Guidance: Answer in writing from memory, then check the key. Repeat after two days and after a week. -->

1. An acquirer trades at 20x earnings and pays 25x for a target, all in stock. Accretive or dilutive before synergies?
   Explain with earnings yields.
2. New debt costs 7% pre-tax and the tax rate is 25%. The target is bought at 12x earnings, all in debt. Accretive or
   dilutive before amortisation and synergies?
3. An acquirer has net income USD 50m, 25m shares and a share price of USD 40. It buys a target with net income
   USD 6m for USD 160m in stock. Compute the pro forma EPS, the accretion and the pre-tax synergies needed to break
   even (tax 25%).
4. Why do many acquirers report an EPS that excludes amortisation of acquired intangibles? What is the risk?
5. An acquirer with 100m shares issues 20m shares on 1 July to buy a target. What weighted average share count enters
   that year's basic EPS under IAS 33?
6. Give two reasons why accretion should not be the decision rule for an acquisition.
7. Rank cash on hand, new debt and new stock by their usual after-tax earnings cost, and explain why.
8. In a stock deal the target's holders will own 30% of the combined company but contribute 25% of its net income.
   What does that suggest?
9. An acquirer has net debt USD 900m and EBITDA USD 300m. It borrows USD 600m to buy a target with EBITDA USD 100m.
   What is pro forma net debt to EBITDA?
10. Under a fixed exchange ratio, what happens to the value received by the target's holders if the acquirer's share
    price falls 10% before closing? Who bears that risk?

## Answer key

<!-- Guidance: Check only after writing your own answers. Note why a wrong answer was wrong, not only the right one. -->

**Worked example B.** Quick test: R's P/E (18.0x) is above the P/E paid (16.2x), so the all-stock deal is
**accretive** before amortisation. New shares = 486 / 27 = **18.0m** (`=486/27`). Pro forma EPS = 180 / 118 =
**1.5254**, accretion **+1.69%** (`=(180/118)/1.5-1`). With amortisation: (180 - 9) / 118 = **1.4492**, accretion
**-3.39%** (`=((180-12*0.75)/118)/1.5-1`). Amortisation changes the sign: reported EPS is dilutive. Tell the board
that the deal is accretive on cash EPS, dilutive on reported EPS, and that neither says whether the 35% premium is
covered by synergies.

**Self-test.**

1. Dilutive. Each new share costs 1/20 = 5.00% of earnings and buys 1/25 = 4.00%.
2. Accretive. After-tax debt costs 7% x 0.75 = 5.25%; the target yields 1/12 = 8.33%.
3. New shares = 160 / 40 = 4.0m. Pro forma EPS = (50 + 6) / 29 = **1.9310** against 2.00, **-3.45%**
   (`=(56/29)/2-1`). Break-even pre-tax synergies = (2.00 x 29 - 56) / 0.75 = **USD 2.67m** (`=(2*29-56)/0.75`).
4. Amortisation of acquired intangibles is a non-cash charge created by the deal's accounting, and the buyer may also
   be investing to maintain those assets; excluding it helps compare with organic growth. The risk is that adjusted
   EPS hides the full price paid, and that the same intangibles need real spending to keep their value.
5. 100 + 20 x 6/12 = **110m** shares.
6. It ignores the premium relative to synergies, and it ignores the risk added by debt or the dilution of control by
   stock. Cheap debt makes almost any cash deal accretive.
7. Usually cash on hand (forgone interest after tax, lowest), then new debt (interest after tax), then stock (earnings
   yield, highest unless the acquirer's P/E is very high). The order can change when interest rates are high or the
   acquirer's P/E is very high.
8. The acquirer is giving away a larger share of ownership than the earnings it receives: it is paying a premium in
   shares, which synergies must cover.
9. (900 + 600) / (300 + 100) = **3.75x**.
10. The number of shares is fixed, so the value received falls about 10%. The target's holders bear that price risk;
    a fixed-value offer (floating ratio) moves it to the acquirer's holders. See mba/mba-deal-structuring-card.
