## Key takeaways

- Secondary shares commonly trade at a 10-30% discount to the last round, but the headline discount is a composite of vintage: roughly 60% below for 2021-priced companies and near 0% for 2025-2026 rounds.
- A ROFR waiver clears only the contract. Board consent, certificate legends, transfer-agent instructions, and a securities-law resale exemption all survive it, and a defective historical ROFR notice can void the stake you are buying.
- Form D shows the offering target and amount sold, not price per share, so treat it as a signal that a round opened, not proof it closed or evidence of valuation.
- In block trades sellers concede 20-30% off the last preferred price while buyers open at 50%+, a structural 20-30 point spread driven by information asymmetry and stack risk, not haggling style.
- Refolk's index finds a single UK Head of Secondaries, at Isomer Capital, which is why most secondary diligence is run by generalists who need an ordered playbook with go/no-go gates.
- Common stock sits behind preferred in the liquidation stack, so anchoring common shares to the last preferred price per share overpays; run the waterfall and apply a class discount.

You have been offered a chunk of a private company's shares through a secondary, and you need to decide whether to buy in and at what price. This guide is for early-stage investors, platform and talent partners at funds, and angels who buy existing shares rather than write into a primary round. It gives you an ordered procedure with named public sources and go/no-go gates: identify who is selling and why, confirm the stake can legally transfer, reconstruct a defensible price against the last round and share class, and reach a wire-or-walk verdict.

This is a different job from converting a SAFE or comparing a primary round. There you are pricing new money into the company and modelling your own dilution. Here you are buying somebody else's existing shares, which means four things you do not face in a primary: the seller's motivation, the transfer restrictions on those specific shares, the share class you are actually receiving, and the discount to the last round. Miss any one and you wire into a stake that is junior, restricted, or void.

## Why a secondary needs its own procedure

A secondary is the purchase of existing private shares from an existing holder, and it fails on mechanics that a primary financing never touches. The seller is a party to the trade, the shares carry restrictions the company can enforce, and the price has to reconstruct value the last round never published for your class.

The market is large enough that these trades reach ordinary investors regularly, not just dedicated desks. Carta put total venture secondary transaction value at roughly $61.1B in the twelve months ending June 2025, above the $58.8B of VC-backed IPO value in the same window. A driver of that supply is not company weakness but fund distribution pressure: only 30% of 2020-vintage VC funds were generating any LP distributions by the end of Q1 2025. On the sell side of company cap tables, Ledgy's State of Equity survey found 77.8% of businesses said they were very or somewhat likely to run a secondary within twelve months.

**$61.1B - Venture secondary transaction value, 12 months to June 2025**

Above the $58.8B of VC-backed IPO value in the same window, per Carta.

That volume also explains who runs these trades. In Refolk's index of professional profiles, there is only one professional in the United Kingdom with the title Head of Secondaries, at Isomer Capital. Dedicated venture-secondaries expertise is scarce, so most of this diligence falls to generalists, which is precisely why an ordered playbook with named sources and gates beats the definitional explainers that rank for these terms.

## The seller's motivation is the first gate

Before you touch price, establish who is selling, what their cost basis is, and why they are exiting, because the reason separates routine liquidity from distress dressed up as portfolio management. This is a gate, not a footnote: an all-secondary structure, a below-basis sale, or an imminent seller departure is a stop sign.

Routine liquidity has recognisable shapes: portfolio rebalancing by a fund, a founder or early employee taking some chips off the table, or a structured, board-approved tender running alongside a primary round. Distress has its own markers. Watch for an all-secondary round with zero primary capital entering the company, a seller selling below their cost basis, or a seller who departs within 12-18 months of the sale. Early investors trying to exit struggling startups is a known pattern, and founders sometimes block those trades. A secondary run outside a structured process can itself be a signal.

> **Watch out:** A rebalancing narrative is not evidence
>
> The cleanest-looking pitch is "just portfolio management." Test it against seller cost basis, tenure, and whether any primary capital is entering the company. An all-secondary structure or a below-basis sale is distress until proven otherwise.

The corroboration you want is concrete: the seller's basis and holding period, whether they still work at or advise the company, and whether the company is raising primary capital in parallel. If the only capital moving is out the door and the seller is heading for the exit, price stops mattering, because you are buying someone else's escape.

## Confirm the stake and its share class

Establish whether you are buying common or preferred, where it sits in the liquidation stack, and what rights attach, using the charter and cap table rather than the pitch deck. This determines both what you receive and what you should pay.

Preferred stock carries the rights the last round negotiated: a liquidation preference, usually 1x and most commonly non-participating, plus anti-dilution, information, voting, and consent rights. Non-participating 1x means the investor takes the greater of the preference or the as-converted value, not both. Common stock has none of that. It sits at the back of the liquidation stack, and it trades below preferred on the secondary market for exactly that reason. None of these class distinctions appear in Form D; they live in the certificate of incorporation, the cap table, and state filings.

#### The liquidation stack you are buying into

1. **Senior preferred** - First to be paid, may hold seniority over other preferred
2. **Ordinary preferred** - 1x non-participating preference, anti-dilution, information and consent rights
3. **Common stock** - No preference, paid last, trades at a discount to preferred
4. **SPV-wrapped interest** - Economic exposure only unless rights are contractually passed through

*What you receive depends on which layer of this stack your shares occupy.*

The trap is to anchor a common-stock purchase to the last round's price. That round priced preferred. Buying common at a preferred price ignores that common is junior and lacks preference, so you must run the waterfall and apply a class discount. If the offer arrives as a fractional interest in a special-purpose vehicle, the SPV may convey economics only, with no voting, information, or preference rights passing through, and it layers fees on top.

## Map the transfer restrictions before anything else clears

Private shares carry contractual and statutory restrictions that can block or void a transfer, and the right of first refusal, the one everyone focuses on, is the weakest gate. Read the governing agreements and confirm the historical notice trail before you treat any clearance as real.

The common blockers are a company right of first refusal, a secondary refusal right held by named investors, board or company consent, prohibited-transferee rules, co-sale or tag-along rights, lockups, and the securities legend itself with its transfer-agent instructions. Delaware DGCL Section 202 is the statutory basis that permits written transfer restrictions. The evidence lives in the Right of First Refusal and Co-Sale Agreement, often modelled on NVCA documents, plus the bylaws, the voting agreement, and the certificate legend, which typically points you to the Secretary for the governing agreement.

A ROFR waiver clears only the contract. It stops the company and named investors from stepping in front of your purchase, but board consent, the legend, transfer-agent instructions, and securities law all survive it. The company usually has around a 30-day window to exercise a ROFR after being notified. More dangerous than the waiver you can see is the notice history you cannot: if prior transfers did not follow the ROFR notice procedure, the transfer can be voidable, and a clean-looking cap table can hide a defective prior transfer.

> **Rule:** Clear four gates, not one
>
> A wire is only defensible when all four are cleared in writing: the ROFR (and its notice history), any board or company consent, the legend and transfer-agent process, and a securities-law resale exemption. A ROFR waiver alone clears exactly one of them.

## Confirm the securities-law resale path

Buying restricted stock requires its own securities-law exemption for the resale, separate from any contractual waiver, and your accredited status does not supply it. Get a Rule 144 or exemption analysis on file before you commit.

The original exemption that let the company issue those shares does not cover you reselling them, and being an accredited investor is not itself an exemption. The relevant safe harbor for restricted shares is Rule 144, which sets a holding-period clock: six months for reporting issuers and one year for non-reporting issuers, which covers most private companies. Meeting the conditions is not the end of it. Only a transfer agent can remove a restrictive legend, even after Rule 144 conditions are satisfied, so budget time for that mechanical step rather than assuming the shares trade freely on close.

I ran this search: `Startup lawyers who have handled ROFR and co-sale waivers for Series B and later secondary transfers.` - [see the full result list](https://www.refolk.ai/s/5p924dehw5).

*Returns named practitioners who have actually run the transfer-clearance work, so you can staff counsel instead of guessing at the notice trail.*

Because dedicated secondaries lawyers and specialists are thin on the ground, sourcing the right counsel is often the hardest part of clearing these gates. [Refolk](/) lets you ask for the people who have done this specific work in plain English and get them back with their firms attached, rather than cold-calling generalists who will bill you to learn the mechanics.

## Reconstruct the last round and build a defensible price

Anchor to the last preferred price per share, run the liquidation waterfall, then discount for share class, staleness, illiquidity, and demand, treating the headline discount-to-last-round as a check rather than the method. Public sources will give you the round's date and rough size, not its price.

Start on EDGAR with the issuer's Form D. It must be filed within fifteen days of first sale, where the date of first sale is when the first investor irrevocably committed. It discloses the target offering amount, the amount sold to date, the date of first sale, the security type, and named officers and directors. It does not disclose price per share, and it signals that an offering opened, not that a round closed. Pull the date, record the size, compute how many months old the round is, and corroborate price per share from the actual deal documents.

#### From last-round evidence to a wire price

1. **Pull Form D** - Date of first sale, offering size, security type from EDGAR
2. **Corroborate PPS** - Last preferred price per share from deal docs, not Form D
3. **Run the waterfall** - Model liquidation preference and where your class lands
4. **Apply discounts** - Class, staleness, illiquidity, and demand adjustments
5. **Net for structure** - Strip SPV fees and confirm rights actually pass through

*Each stage feeds the next; the waterfall, not the headline discount, carries the price.*

Now the discount. The common band is 10-30% below the last round, with in-demand names at par or a premium. But that headline is a composite of vintage, not sentiment, and the two datasets below make the point. Marketplace averages swing quarter to quarter, while the discount driven by when the company last raised is far more explanatory.

```table
```

**Secondary discount to last primary round, by source and period**

| Source / period | Discount to last round | Notes |
|---|---|---|
| EquityZen Q1 2025 | 28% avg | Marketplace indications |
| EquityZen Q2 2025 | 13% avg | 21% of trades at a premium |
| EquityZen Q3 2025 | 29% avg | "Return to normal" |
| ESO Fund (general) | 10-30% typical | Par or premium if in-demand |
| Carta block trades | 20-30% (sellers) / 50%+ (buyers sought) | Gap is the negotiation spread |

The last row is the most useful. In block trades sellers concede 20-30% off the last preferred price while buyers open at 50%+, a spread of roughly 20-30 percentage points. That gap is structural, driven by information asymmetry and common-versus-preferred stack risk, not by negotiation style. Do not expect to close it with charm.

**Discount driven by the vintage of the last round**

| Last round vintage | Approximate discount to that round |
|---|---|
| 2021 | ~60% below |
| 2024 | 17% |
| 2025 | 1% |
| 2026 | Full value / ~0% |

This single-source illustration, from Chronograph data, shows the mechanism plainly: your discount tracks when the company last raised. The 2021 marks were set at the top of a cycle, so shares priced then can sit around 60% below that number today, while a 2025 or 2026 round trades near full value. A round older than roughly 18 months may not reflect current value at all, so compute months since first sale and stress the mark against public comparables.

> The headline discount to last round is a composite of vintage, not a read on sentiment.

Marketplaces lead with discount-to-last-round because it is simple. Veteran secondaries investors and analysts argue the opposite: lead with the waterfall and company fundamentals, and treat the discount as secondary. Follow them. If the round is stale or the class is junior, the discount is an output of your model, not an input you borrow from a marketplace print.

## Adjust for structure and fees

If the stake comes through an SPV, your net exposure per share differs from the headline price because of fees and because rights may not pass through. Resolve both before you sign.

A fractional SPV interest adds management fees, carry, administration costs, and spreads, so the price you pay per share of underlying is higher than the quoted number. Worse, an SPV or transferee only receives preferred rights if the transaction structure and the company's agreements actually pass them through. Synthetic or derivative structures may convey economic exposure only, and then your outcome also depends on the counterparty's creditworthiness. Read the SPV operating agreement against the company's voting and information-rights agreements. If you are paying a preferred price for economics that arrive stripped of voting, information, and preference, you are overpaying for a right you do not receive.

The pricing logic is a cascade: pay less for common than for preferred, and less again for an SPV interest that strips rights or layers fees. Net exposure per share, after every layer, is the number that goes into the memo.

## Run the procedure end to end

The following sequence takes a typical offer from first look to verdict in roughly two to three weeks, with counsel working in parallel on the transfer and securities gates. Each step names who does it and what "done" looks like, so you can stop at any red gate without wasting the next stage's effort.

#### Secondary diligence, in order

1. **Identify the seller and their motivation** - Buyer or analyst, 1-3 days. State who is selling, their cost basis, and why. All-secondary structure, a below-basis sale, or an imminent departure is a red gate.
2. **Confirm the stake exists and what class it is** - Buyer plus counsel, 2-5 days. Establish common versus preferred, seniority, and liquidation-preference terms from the charter and cap table, not the pitch.
3. **Map transfer restrictions and clearance path** - Counsel, 3-7 days. Read the ROFR and co-sale agreement, bylaws, and voting agreement; confirm ROFR notice history was followed. Produce a written waiver plan, consent requirements, and legend and transfer-agent process.
4. **Confirm the securities-law resale path** - Counsel, concurrent. Put an exemption or Rule 144 analysis on file. Accredited status is not an exemption; note the holding-period clock, one year for non-reporting issuers.
5. **Reconstruct the last primary round** - Analyst, 1-2 days. Pull the Form D on EDGAR, record date of first sale and offering amount, and compute round staleness. Treat Form D as a signal, not proof of price.
6. **Build the price** - Analyst, 2-4 days. Anchor to the last preferred price per share, run the waterfall, then discount for class, staleness, illiquidity, and demand.
7. **Adjust for structure and fees** - Analyst, 1 day. Compute net exposure per share after all SPV and fee layers, and confirm whether preferred rights actually pass through.
8. **Reach a wire-or-walk verdict** - Buyer or IC, 1 day. Write a go/no-go memo confirming each gate above is cleared, and state the price you will wire.

## How this goes wrong

Most secondary losses come from a small set of repeatable errors, each of which looks like a green light until you check the underlying document. Treat this section as the highest-value part of the playbook: these are the false positives that pass a casual read.

```table
```

| Failure mode | The false positive | What to check |
|---|---|---|
| Treating Form D as the price | Reading a large "target" as a closed valuation | Pull the filing on EDGAR; corroborate PPS from deal docs |
| ROFR waiver equals clearance | Wiring after a waiver with no resale exemption | Separate securities-law and Rule 144 memo; transfer-agent legend process |
| Buying common at a preferred price | Anchoring junior common to the last round PPS | Run the waterfall and apply a class discount |
| Missing an SPV rights strip | Paying for "preferred" you do not actually receive | Read the SPV operating agreement against company voting and IRA agreements |
| Stale-round mispricing | Full-value payment on a 2021 mark | Compute months since first sale; stress against public comps |
| Ignoring ROFR notice history | A clean-looking cap table hiding a defective prior transfer | Trace notice compliance across prior rounds |
| Misreading seller motivation | Accepting a "portfolio management" narrative | Seller cost basis, tenure, and whether primary capital is entering |

The two that catch experienced buyers most often are the notice-history trap and the SPV rights strip. A voided prior transfer can void the stake you are buying no matter how clean the paperwork you were handed looks, so the notice trail has to be traced, not assumed. And an SPV that conveys economics only turns a "preferred" purchase into an unsecured bet on a counterparty, at a preferred price. Both hide in documents you have to actually open.

> **Tip:** Check whether the trade already has a print
>
> Platforms that record prior secondary activity can tell you whether these shares, or shares of the same class, have traded before and roughly where. A prior print is a sanity check on both the price and the transferability you are being sold.

## Before you wire

Run this checklist against the finished memo. If any item is unchecked, the answer is walk, or condition the wire on clearing it first.

#### Wire-or-walk final check

- [ ] You can state the seller, their cost basis, and their reason for selling in one sentence
- [ ] No red gate is open: no all-secondary structure, no below-basis sale, no imminent seller departure
- [ ] Share class is confirmed from the charter and cap table, not the pitch
- [ ] A written ROFR waiver plan exists and prior notice history has been traced clean
- [ ] Board or company consent requirements are identified and satisfied
- [ ] A securities-law exemption or Rule 144 analysis is on file, with the legend removal process understood
- [ ] Form D is pulled, round date and size recorded, and staleness computed
- [ ] The price is built from the last preferred PPS and the waterfall, not borrowed from a marketplace discount
- [ ] Net exposure per share is computed after all SPV and fee layers
- [ ] For any SPV, you have confirmed which rights actually pass through

## Keeping the price current

A secondary price is perishable, so the one thing to re-check before you actually wire is whether the anchor still holds. The two variables that move fastest are round staleness and market-wide discounts, and both have a mechanism you can re-run rather than a number to memorise.

Re-pull the Form D date and recompute months since first sale; if the company has raised again, your anchor changes entirely. Re-check the current discount band against a recent marketplace print, but remember it is a composite of vintage: a 2021-priced company and a 2025-priced company will diverge sharply even in the same quarter. And because forced-seller supply from funds under distribution pressure can widen discounts even for strong companies, watch whether the seller is a fund managing DPI rather than a founder taking liquidity. When you next need to staff a deal like this, the scarcity of dedicated secondaries specialists is the binding constraint, and it is the one Refolk is built to relieve: ask for the counsel, SPV managers, or secondaries leads you need in plain English and get named people back.

## Frequently asked questions

### Does a ROFR waiver mean I can safely buy the shares?

No. A right of first refusal waiver is contractual clearance only. It clears the company and any named investors from stepping in front of your purchase, but it does not clear board or company consent rights, the restrictive legend, transfer-agent instructions, or securities law. You still need a separate resale exemption and a Rule 144 analysis on file, plus confirmation that prior ROFR notices were followed, since a defective historical notice can make the transfer voidable.

### Can I use Form D to find the price per share of the last round?

No. Form D discloses the offering target, the amount sold to date, the date of first sale, the security type, and named officers, but not price per share and not full share-class economics. It signals that an offering opened, not that a round closed. Use it to date the round and estimate size, then corroborate price per share and liquidation terms from the charter, the cap table, and the deal documents.

### What discount to the last round should I expect on a secondary?

The common quoted band is 10-30% below the last round, with in-demand names at par or a premium. One marketplace reported quarterly averages of 28% in Q1 2025, 13% in Q2 2025, and 29% in Q3 2025. But the headline figure is really a function of vintage: shares priced in a 2021 round can sit around 60% below that mark, while 2025-2026 rounds trade near full value. Price against the waterfall first, then treat the discount as a check.

### How is buying common stock different from buying preferred on a secondary?

Common stock sits at the back of the liquidation stack, so it lacks the liquidation preference, anti-dilution, information, and consent rights that preferred carries, and it trades at a discount to preferred as a result. Do not anchor common shares to the last preferred price per share. Run the liquidation waterfall and apply a class discount, and if the offer comes through an SPV, confirm whether any preferred rights actually pass through the structure.

### What does Rule 144 mean for reselling private shares I buy?

Rule 144 sets a holding-period clock before restricted shares can be resold under that safe harbor: six months for reporting issuers and one year for non-reporting issuers, which covers most private companies. Meeting the conditions does not automatically clean the certificate. Only the transfer agent can remove a restrictive legend, even after Rule 144 conditions are satisfied, so budget time for that process rather than assuming the shares are freely tradeable on close.

### How do I tell routine liquidity from distress in a secondary?

Look at seller cost basis, tenure, and whether primary capital is entering the company. Routine liquidity looks like portfolio rebalancing, a founder or employee taking chips off the table, or a board-approved tender alongside a primary round. Distress looks like an all-secondary round with zero primary capital, a sale below cost basis, or a seller departing within 12-18 months. A secondary running outside a structured process can itself be a signal, so evaluate why the seller is exiting before you price anything.
