PIPE
Also known as: Private investment in public equity, Private placement into a listed company
A listed company selling shares privately, at a discount, usually because the public route is not open to it.
1 · SnapshotThe one idea to remember
2 · BeginnerWhat actually happens?
A listed company can sell shares to the public, or it can sell them privately to one investor who agrees to buy a large amount. The second is a PIPE — private investment in public equity.
Why would a company do that rather than sell into the market? Usually because it cannot. The market may be closed, the company may be in difficulty, or it may need a decision this week rather than in a month. A single investor who is willing to look properly and commit quickly is worth a discount.
The investor's side is the mirror image. It gets a large position at a price below the market, plus whatever protections it can negotiate — a board seat, a veto, a guarantee against later issues at a lower price.
The awkward part is information. To decide, the investor needs to know things the market does not. From that moment it is an insider and cannot trade the shares at all, until the deal is announced. Managing that window is the whole compliance exercise around this transaction.
- 1
Approach1–4 wks
The company or its adviser approaches investors who can commit quickly and take an illiquid position.
- 2
Diligence1–3 wks
The investor sees information the market does not, and becomes an insider for the duration.
- 3
Negotiation1–3 wks
Discount, board rights, anti-dilution and the restrictions on selling are agreed.
- 4
Announcement1 day
The placing is announced and the investor ceases to be an insider.
- 5
Resale registration4–12 wks
The shares are made freely tradable, which is when the investor's position becomes liquid.
Insider control — The company's compliance function decides. Everybody who has seen the information is restricted until announcement, and a leak in that window is a market-abuse question.
Existing shareholders' rights — The register decides. Pre-emption rules limit how much can be issued to new investors without offering it to existing ones first.
Who is on the deal
| Who | Side | What they are actually for |
|---|---|---|
| The company | Sell side | Needs money quickly, or from a specific investor, and accepts a discount for it. |
| The investor | Buy side | Commits fast, takes an illiquid position and negotiates protections for it. |
| Existing shareholders | Neither | Are diluted at a price they did not set, which is why pre-emption rules cap how much of this is allowed. |
| The company's compliance function | Neither | Controls who has the information and when they may trade again. |

What decides whether it completes
Not how hard this is, and not a rating — there is deliberately no total. It says which of five blockers decides whether this transaction happens at all, in the same order on all 70 transaction types so they can be compared. This publication's own reading; see the notice below.

What decides it here. A company selling shares privately is usually doing so because the public route is not open, and the investor prices that. The discount and the protections are the negotiation, and pre-emption rules cap how much can be sold this way before existing shareholders have to be asked.
3 · IntermediateHow it runs in practice
What the investor negotiates besides price
- Registration rights — a commitment to make the shares freely tradable within a stated period. Until then the position is illiquid, and that illiquidity is part of what the discount pays for.
- Anti-dilution protection — if the company later issues shares more cheaply, the investor's price is adjusted.
- Board representation, or observer rights.
- Consent rights over further issuance, major disposals or new debt.
- Standstill and lock-up — the company usually wants limits on the investor buying more or selling quickly.
Structured PIPEs, and why to read them carefully
Where a company is in real difficulty, the instrument is often not ordinary shares. Convertible preferred stock, or a convertible whose conversion price resets downwards if the shares fall, transfers most of the risk back to existing holders — the lower the price goes, the more shares the investor receives. These structures have a poor reputation for a reason, and they are entirely disclosed. Whether one is appropriate is a question for the company's board; what a reader should do is find the conversion mechanics before reading the headline amount raised.
Pre-emption is the cap
In jurisdictions with statutory pre-emption rights, a company may issue only a limited proportion of its capital to new investors without asking existing shareholders first. That limit is why very large PIPEs need a shareholder vote, and why in some markets this transaction is rare while in others it is routine.
Where it shows up most
Two places. Companies in stress, raising quickly from a specialist investor. And de-SPAC mergers, where committed new money is needed to replace whatever the shell's holders redeem — there, the PIPE is not an emergency but a structural part of the deal.
4 · AdvancedThe numbers & the documents
The insider window, in practice
An investor that receives material non-public information is restricted until it is announced. Three consequences follow:
- The diligence period is compressed, because a large investor cannot be restricted in a position indefinitely.
- Some investors will not be wall-crossed at all, and can only participate on public information.
- The company must announce promptly once the deal is agreed, which is why these are frequently signed at night and announced before the open.
The same machinery governs an accelerated bookbuild, with the difference that there the restricted list is a handful of funds for a few hours, and here it is one investor for several weeks.
What the discount is actually paying for
- Illiquidity until the shares are registered.
- Size — a position that cannot be exited without moving the price.
- Adverse selection — the investor knows that the company came to it rather than to the market, and prices what that implies.
- Speed — a decision made in days on information nobody else has seen.
How existing shareholders should read one
They are being diluted at a price they did not set, by a board exercising an authority they granted. That can be entirely the right decision — a company that survives because one investor moved quickly is worth more than one that did not — and it can also be a board choosing the easy route over the fair one. The published terms answer the question: the discount, the protections given, and whether existing holders were offered anything at all.
The reset structure, spelled out once
If a convertible resets its conversion price downwards as the share price falls, the investor receives more shares as the shares get cheaper. Its position is largely insulated from the fall; the existing shareholders absorb it through dilution. That is a legitimate structure, it is disclosed, and its effects are frequently not understood by the holders they land on — which is exactly why it belongs in a page like this.
The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.

Now say it back
Close the page and give PIPE in four sentences. It takes a minute and it is the only way to find out whether reading it was enough.
- Who wants what — name both sides and what each one is actually trying to get.
- What has to happen, in order — the three or four stages, not the whole timetable.
- Where the money comes from — cash, new shares, or borrowed; somebody has to fund it.
- What kills it — the ordinary way, not the dramatic one.
