Halden is issuing shares to raise $1 billion. What do existing owners actually give up?
They give up a fraction of the company. They do not automatically give up value. The slice gets smaller. Whether it is worth less depends on the price of the new shares and on what the cash becomes.
Sample explanation. Halden Health is a composite created for this edition, not a real company. Figures are stipulated to show the mechanism. They are not reported results.

One-minute answer
This is a primary issue: the company sells new shares and receives the cash. Existing owners go from 100 percent of Halden to 80 percent, because the share count rises from 100 million to 125 million. That is the dilution of their fraction. It is arithmetic, and it is not the whole of the economics.
Hold the existing business constant and treat the new cash as worth its face value. Equity value becomes $6 billion. Divided by 125 million shares, that is $48 a share. Old owners’ 100 million shares are then a claim on $4.8 billion, down from $5 billion. New investors pay $1 billion for a claim worth $1.2 billion in that arithmetic. The $200 million gap is what an issue below post-money value transfers.
That calculation stops at the moment cash arrives. Halden’s stated use is an acquisition. No target and no purchase price are stipulated, so it is not possible to say whether the cash, once spent, is worth more or less than $1 billion. A smaller fraction of a more valuable firm can be worth more than the larger fraction was. A smaller fraction of an overpaid deal is worth less. The percentage, alone, does not choose.
What happened?
In this sample, Halden Health issues 25 million new shares at $40, raising $1 billion of cash. Before the issue, Halden has 100 million shares at a stipulated price of $50, an equity value of $5 billion.
The sample stipulates the share count, the pre-issue price, the number of new shares, and the issue price. It stipulates that the cash goes to Halden, not to selling shareholders. A secondary sale — old owners selling to new owners — would move cash between investors and leave the company’s cash unchanged. That is a different transaction, and it is not this one.
The use of proceeds is described only as an acquisition. No target, no enterprise value, and no financing mix beyond this equity are given. The issuance can be analyzed. The acquisition cannot.
What does that actually mean?
Dilution is a change in how ownership, voting, and claims on residual cash flow are split. In a one-class share structure, which this sample assumes, economic ownership and voting move together. Existing owners have a thinner claim on whatever Halden becomes.
They have also, through the company, taken in $1 billion. If you ignore the cash and look only at the percentage, you will conclude that owners lost 20 percent of the firm. They did lose 20 percent of the claim. Twenty percent of the old firm would be $1 billion. They gave up a claim of that economic size only if the new shares were a gift. They were not. The new shareholders paid $40. The question is whether $40, and the use of the cash, was enough.
Earnings per share can fall even when the company’s total earnings do not, because the denominator rose. A lower earnings-per-share figure on the morning after an issue is not, by itself, evidence that the issue destroyed value. It is evidence that the same earnings are being shared more widely, before any return on the new cash.
How it works
The issuance, with the business held constant
| Shares before | 100 million |
|---|---|
| Equity value before | $5 billion |
| Shares issued by the company | 25 million at $40 |
| Cash in | $1 billion |
| Shares after | 125 million |
| Existing owners’ fraction | 80% |
| Equity value, cash at face | $6 billion |
| Existing owners’ claim | $4.8 billion |
What has to happen after the cash arrives

Larger or smaller pie
Depends on what the cash buys
Fraction and value move on different clocks
Before the issue, owners hold 100 million shares of a $5 billion equity, or $50 a share. After the issue, if the operating business is unchanged and cash is worth cash, the equity is worth $6 billion and each share is worth $48. Old owners still hold 100 million shares. Their wealth in this frozen picture is $4.8 billion. The percentage fell from 100 to 80. The dollar claim fell by $200 million, not by $1 billion.
The reason the dollar claim falls at all is the discount to the post-money value. New investors buy at $40 what the frozen arithmetic says is worth $48. That $8 difference, across 25 million shares, is the $200 million transfer. Issue the same shares at $48 and, in this frozen picture, old owners do not lose dollars. Their percentage still falls. Percentage dilution and value transfer are related, and they are not identical.
Then the cash has to be used
The frozen picture is a baseline, not a forecast. It assumes the acquisition has not happened. The moment Halden spends the $1 billion, cash becomes whatever was bought. If that asset is worth more than $1 billion, post-deal equity exceeds $6 billion and old owners can be better off in dollars despite owning 80 percent. If the asset is worth less, the damage stacks on top of the issuance discount.
If the thing being bought is a company, the relevant price is not a headline equity value alone. Enterprise value — equity plus debt minus cash — is the fuller description of what a buyer takes on. This sample does not name a target, so that bridge cannot be built. The concept still tells you which number you would need.
Follow the money
New investors
Pay $1 billion and receive 25 million shares, 20 percent of the post-issue company. In the frozen arithmetic they receive a claim worth $1.2 billion.
Halden
Receives $1 billion of cash. Assets and equity rise by the proceeds, ignoring fees, which are not stipulated. The company does not “lose” cash in a primary issue. It gains cash and issues a claim.
Existing owners
Keep 100 million shares. Their fraction falls from 100 percent to 80 percent. In the frozen arithmetic their claim falls from $5 billion to $4.8 billion.
The acquisition
Not priced. Until a target and a price exist, the $1 billion cannot be followed past the cash account. Spending it will replace cash with an asset, and possibly with that asset’s debt.
Why it matters
Existing owners
They are selling a slice of the future firm in exchange for a partner’s cash. The loss of percentage is certain under the stipulation. The loss of wealth is not. It depends on the $40 price and on the acquisition that has not been specified.
New investors
They are paying $40 for shares that the pre-issue market marked at $50, in a company that will hold their cash. The discount compensates them only if the post-money value and the eventual deal do not erase it.
Halden
The firm is more liquid by $1 billion and more widely owned. What it can do with the cash is larger. What each old share owns of that future is smaller.
Concepts underneath this story
- ConceptDilutionDilution is a change in the share of the firm each owner holds. Whether owners lose value depends on what was received for the new shares.
- ConceptEnterprise valueMarket capitalization is the price of the shares. Enterprise value is a way of stating the price of the whole firm, once debt and surplus cash are in the picture.
What we know and what we don’t
This is a sample, so the starting point is stipulated rather than reported. A published explanation of a real event would reserve “Reported” for facts taken from primary documents, and would keep the other categories separate.
Stipulated
- Halden Health is a composite. This is not a reported offering.
- Shares outstanding before the issue: 100 million. Pre-issue price: $50. Pre-issue equity value: $5 billion.
- New shares: 25 million, sold by the company at $40, for $1 billion of proceeds.
- The sample assumes one share class, so voting and economic ownership move together.
Derived
- Post-issue share count is 125 million. Existing owners hold 80 percent.
- If the operating business is unchanged and the new cash is worth $1 billion, equity value is $6 billion, or $48 a share.
- Old owners’ claim in that picture is $4.8 billion. The $200 million difference is the gap between the $40 issue price and the $48 post-money value, times 25 million shares.
Estimates
- The pre-issue price of $50 is stipulated, not estimated from a market.
- No value is estimated for the acquisition. Fees and option overhang are not estimated either.
Interpretation
- Calling the issue “dilutive” is accurate as a description of the fraction and, in the frozen arithmetic, of a $200 million transfer. It is not a verdict on the acquisition.
- A lower earnings per share immediately after the issue would describe the wider denominator. It would not, alone, describe whether owners were helped.
Uncertain
- What will be bought, at what enterprise value, and whether that asset is worth at least the cash plus any claims assumed.
- Whether the real issue price would clear at $40 once a use of proceeds is known.
- Fees, other share classes, convertibles, and unissued equity awards, none of which are in the base case.
