Pre-IPO Investing Risks: What Can Go Wrong Before a Company Lists

The risks fall into three groups: the company, the share you buy and the way you hold it. The table names each one, what happens and what to check.

Vehicle risks, such as fee layers, operator risk and late tax forms, have their own guide: SPV risks. What the shares themselves entitle you to is explained in pre-IPO shares.

Pre-IPO shares are sold in private offerings that the SEC does not register. US rules mostly limit them to accredited investors: individuals with net worth over $1M excluding their home, or income over $200K ($300K with a spouse) in each of the last two years. Rule 506(b) also allows up to 35 non-accredited buyers in any 90 days, each able to judge the risks.

That gate is a warning sign in itself. The SEC says many pre-IPO offerings aimed at the general public may be illegal. Its investor alert lists the red flags:

• A date for the IPOThe seller says the IPO is “imminent” or will happen “this year.” No private seller controls that date.
• No entry testThere are no investment limits and no questions about your income or net worth.
• “No upfront fees”The price hides a large, undisclosed markup over what the seller paid.
• ScarcityThe seller claims a small allocation, or a price below the expected IPO price.
• Shares that do not existThe seller does not own the shares and uses investors’ money for other purposes.

A few SEC rules decide who can buy before an IPO and when they can sell. They protect investors in some ways and restrict them in others.

You invest $100,000 in a private company at $40 a share and receive 2,500 shares of common stock. Here is what the same stake is worth under four outcomes, before fees and tax.

The same stake ends up worth anything from $0 to $150,000. Only one outcome returns more than you paid. In the sale case, common holders get $10 a share because the preferred stock is paid first. That is a 75% loss, even though the company found a buyer.

An IPO solves the main pre-IPO problem: the shares get a market. It brings new risks of its own, and the SEC lists several of them.

• The IPO price is an estimateThe company and its banks set it by negotiation. The SEC says it “may bear little relationship to the trading price” soon after.
• Support endsBanks can buy shares in the first days to keep the price near the offer. Once they stop, the price may fall.
• The lock-up endsWhen the lock-up expires, many holders can sell at once, and the price can drop. See lock-up expiration.
• Voting power stays with foundersIn a dual-class company, founders hold shares with more votes. Public holders may have little say.
• Lighter disclosure at firstAn emerging growth company, generally one with under $1B in revenue, can phase in some public-company rules for up to five years.

If you held shares before the listing, your gain is measured at the price when you can finally sell. The first-day price matters less. IPO pop and pre-IPO vs IPO explain the gap between the two.

No investment in a single new company is safe. The SEC calls IPOs “risky and speculative investments.” It also says its review of the prospectus is not an approval of the deal and does not confirm the information is complete.

Compared with buying before the IPO, a listed share has two protections. You can sell it on any trading day. And the company must publish a prospectus and then quarterly and annual reports. A pre-IPO buyer has neither. The trade-off is price: early buyers take on these risks in exchange for an earlier, private price. The mechanics of the listing are in how IPOs work.

1. 01
   Confirm the shares existAsk who holds them now and whether the company has approved the transfer.
2. 02
   Name the classCommon or preferred, and what is paid ahead of it. Liquidation preference explains the order.
3. 03
   Compare the priceSet it against the last round and the company’s 409A valuation, the appraisal of its common stock.
4. 04
   Count the layers and feesEach fund or SPV between you and the shares charges its own fees and has its own manager.
5. 05
   Look up the filingsSearch EDGAR for the Form D notice of the offering.
6. 06
   Plan for no exitSize the position so that losing all of it would not change your plans.

• Treating the last round as your priceThe round price is for preferred stock with its own rights. Common stock is usually worth less.
• Expecting an IPO on a scheduleNobody outside the company controls the date. A seller who promises one is a red flag.
• Ignoring dilutionEach new round shrinks your percentage. See dilution.
• Forgetting the lock-upAn IPO does not mean you can sell. Expect to wait about six months after listing.
• Putting too much into one companyA single private company can fail. One position should not decide your finances.

• Buying before a listingHow a private sale shortly before an IPO works: pre-IPO placement.
• Share classesWhy preferred and common stock pay differently: common stock vs preferred stock.
• Valuing illiquid sharesHow appraisers price the wait to sell: discount for lack of marketability.
• Before and afterWhat changes for a holder on listing day: pre-IPO vs IPO.
