How a PIPE transaction works, end to end

A PIPE transaction runs in a fixed sequence: prospective investors are wall-crossed under Regulation FD, terms are agreed on a term sheet, confirmatory diligence is done, a securities purchase agreement and registration rights agreement are signed, the transaction is announced, the securities settle against payment, and a resale registration statement follows.

Key takeaways

• Announcement is the hinge, not closing. Everything before it is confidential and every wall-crossed investor is restricted from trading. Everything after it is public, and the investor is free again whether or not the deal closes.
• The share reserve is checked first, not last. Authorised but unissued shares must cover the securities, the warrants and any conversion capacity. If they do not, the transaction needs a shareholder vote before it needs an investor.
• The registration undertaking is the deal. Filing and effectiveness deadlines, and the damages for missing them, are negotiated harder than the discount because they decide when the investor can actually sell.
• The transfer agent is on the critical path twice. Once to issue legended securities at closing, and again to remove the legend when the resale statement is effective or Rule 144 becomes available.

The same transaction, under several names

An issuer meets this deal under a handful of labels and they all describe the same thing. A PIPE offering is the transaction seen from the issuer's side. A PIPE placement is the same thing seen from the placement agent's side. A PIPE round borrows venture vocabulary and usually signals a first-time issuer or a recently listed one. PIPE securities are simply what the investor ends up holding. And a PIPE private placement is a redundancy, because every one of these is a private placement by definition.

The only distinction that carries legal weight is between an unregistered issuance and a registered one, and that is the subject of PIPE versus registered direct offering.

Who does what

Seven parties touch a PIPE transaction, and a deal stalls where one of them is unprepared rather than where the terms are hard.

The sequence, stage by stage

1. Wall-crossing under Regulation FD

   Before an investor is told the issuer's name or anything material, it agrees to keep the information confidential and not to trade until the information is public. That agreement is what makes the conversation lawful rather than selective disclosure. The issuer decides how many investors to cross, because every crossing widens the group that knows and cannot trade.

2. Term sheet

   Six terms carry the deal: amount, instrument, price or pricing mechanic, warrant coverage, the registration undertaking, and the conditions to closing. Everything else is documentation. The pricing mechanic is where a fixed price and a formula referenced to a later VWAP window diverge, and it should be settled here rather than in the purchase agreement.

3. Confirmatory diligence

   The investor asks for a fully diluted capitalisation table, the authorised and unissued share count, every existing convertible, warrant and equity facility, the transfer agent's details and any restriction on the register, the audit position and any going-concern language, material litigation, and whether the company has ever been a shell.

4. Documentation

   A securities purchase agreement with disclosure schedules, a registration rights agreement, the instrument where the securities are warrants, preferred stock or a note, an officer's certificate, a legal opinion, and an irrevocable instruction to the transfer agent. Representations about capitalisation and about the shell history are the ones that get negotiated hardest.

5. Signing, announcement and the current report

   Signature makes the agreement binding and fixes the reference price where the price is fixed. A US reporting issuer then files a current report on Form 8-K for the material definitive agreement, and separately for the unregistered sale where it exceeds 1% of the class outstanding, or 5% for a smaller reporting company. Announcement releases the wall-crossed investors.

6. Closing and settlement

   Conditions precedent are satisfied, funds and securities move against each other, and the securities are issued in book-entry form with a restrictive legend. The exchange is notified of the additional shares. Nothing about the securities is saleable at this point, and the parties are relying on the registration undertaking signed at stage four.

7. Resale registration and legend removal

   The issuer files the resale registration statement by the agreed deadline and works it through staff comments to effectiveness. When it is effective, or when Rule 144 is available and its conditions are met, counsel issues an opinion and the transfer agent removes the legend so the position can settle in the ordinary way.

What actually breaks a PIPE transaction

The share reserve. Authorised but unissued shares have to cover the securities, the warrants and any conversion capacity, often with a cushion. An issuer that has to increase its authorised capital first has added a shareholder meeting to the timetable.

A capacity rule found late. Nasdaq Listing Rule 5635(d) and the change-of-control test under Rule 5635(b) are run against the agreed price and size. Discovering after the term sheet that the deal needs a vote usually means repricing it or shrinking it. The rule is set out on this site under the Nasdaq 20% rule.

A shell history. If the company is or has ever been a shell company, Rule 144 is unavailable except on the Rule 144(i) conditions, so the resale route depends entirely on a registration statement. Investors price that difference, and some will not proceed at all.

Stale or qualified financials. A registration statement needs current financial statements and a clean consent. An audit that is late, or an auditor that has resigned, stops the resale path regardless of how good the terms were.

A leak. If the price moves before announcement, the reference price moves with it, and the transaction that was agreed no longer exists. This is the practical reason wall-crossing is kept narrow.

PIPE transactions: frequently asked questions

How long does a PIPE transaction take?

There is no reliable timetable, and any provider who gives one before seeing the file is guessing. The variables are the state of the issuer's disclosure record, how quickly counsel on both sides can turn documents, whether a shareholder vote is required, and how fast the transfer agent and the exchange respond. Timing is never guaranteed.

What does wall-crossing mean in a PIPE transaction?

Wall-crossing is the process of bringing a prospective investor inside the issuer's confidential information before a transaction is announced. The investor agrees in advance to keep what it is told confidential and not to trade in the issuer's securities until the information is public. Without that agreement, telling the investor anything material would be selective disclosure under Regulation FD.

What documents does a PIPE transaction use?

A securities purchase agreement with disclosure schedules, a registration rights agreement, the instrument itself where the securities are warrants, preferred stock or a convertible note, an officer's certificate, a legal opinion, and an irrevocable instruction to the transfer agent. Where a placement agent is engaged there is also an engagement letter.

When must a US issuer announce a PIPE transaction?

A US reporting issuer files a current report on Form 8-K for entry into a material definitive agreement, and separately reports the unregistered sale where it exceeds 1% of the class outstanding, or 5% for a smaller reporting company. Announcement is also what releases the wall-crossed investors from the trading restriction they accepted.

What is a registration rights agreement?

It is the contract that turns a restricted security into a saleable one. The issuer undertakes to file a registration statement covering the resale by a stated deadline, to use its efforts to have it declared effective by a second deadline, and to keep it effective for an agreed period, usually with liquidated damages if it misses.

What most often stops a PIPE transaction from closing?

Four things recur: an authorised share reserve too small to cover the securities and the warrants, a shareholder-approval requirement discovered after terms were agreed, a shell-company history that removes Rule 144 from the resale analysis, and stale or qualified financial statements that make a registration statement unfileable.
