Secondary markets price off the last primary round. That is both their signal and their blind spot. When a company last raised at a $20 billion valuation two years ago, every secondary trade anchors to that number — even though the underlying business may have grown, stalled, or quietly deteriorated since then.

For buyers who enter near the last-round price, or at a modest discount to it, a down round is not a theoretical risk. It is a scenario that deserves its own column in your model. This article walks through how to structure that analysis before you sign an indication of interest.

Why a down round hits secondary buyers harder than primary investors

When a company raises a down round — a primary financing at a lower per-share price than the previous round — it typically comes with investor protections that secondary buyers do not receive. Full-ratchet or weighted-average anti-dilution provisions recalculate the conversion price for existing preferred shareholders, effectively giving them more common shares to compensate for the lower valuation. Secondary buyers who hold common shares, or who bought into an SPV that holds common, receive no such adjustment.

Secondary buyers who purchased preferred shares directly fare better on paper, because their liquidation preference is tied to their actual purchase price. But even there, the new preferred investors typically sit ahead of older series in a liquidation stack, which compresses the real value of older preferred positions.

A down round does not just lower the valuation headline — it can restructure who gets paid first on exit, dilute common holders more than preferred, and reset secondary market bids across every comparable issuer.

The four inputs every down-round model needs

You do not need a full discounted cash flow model to stress-test a secondary position. You need four numbers.

Entry price per share (or implied price per unit if via SPV)
Your cost basis, including any SPV fees and carry loaded into the structure. This is what you are defending.
Last-round price per share
The primary round price the secondary market is anchoring to. Your entry price may be at, above, or below this.
Down-round scenario price
Pick a range: 20% down, 40% down, 60% down. Use the company's burn rate, revenue trajectory, and comparable public multiples to set a realistic floor.
Liquidation preference stack
What dollar amount of preferred liquidation preferences sit ahead of you at each scenario price? This determines whether an exit at the down-round price pays you anything at all.

Once you have these inputs, the arithmetic is straightforward. Multiply the down-round scenario price by the fully diluted share count implied by the new round. Then subtract the aggregate liquidation preferences senior to your position. Whatever remains is distributed pro-rata. If the remainder is less than your cost basis, you are underwater.

Working through a simplified example

Suppose you are buying common shares of a private company at an implied valuation of $15 billion — a 25% discount to the last primary round at $20 billion. The company has $8 billion in aggregate liquidation preferences (all the preferred series stacked). The fully diluted share count is 1 billion shares.

At your entry valuation of $15 billion, the equity value available to common is $15 billion minus $8 billion, or $7 billion. Divided by 1 billion shares, that is $7.00 per common share. If you paid $15.00 per implied share, you are already purchasing common equity at a significant discount to the headline but above the intrinsic per-share value after accounting for the preference stack.

Now run the 40% down-round scenario: the new primary round values the company at $12 billion. The liquidity stack is still $8 billion. Common equity: $4 billion. Per share: $4.00. Your $15.00 entry price is now worth less than $4.00 in that exit scenario. The discount to last round you thought you bought is irrelevant — the preferences consumed most of the value.

Buying at a discount to the last primary round does not protect you if the liquidation preference stack is large relative to the equity value at the down-round price. The discount only helps if the exit value clears the preferences first.

What to check in the cap table before running scenarios

The most important document you can request before a secondary purchase is not the most recent financial statement — it is the capitalization table or, failing that, a summary of the liquidation preference stack by series. Many sellers, especially former employees, do not have access to a current cap table. In that case, you should rely on publicly available funding disclosures, SEC filings if any exist, and any term sheets that have been disclosed.

  • Total aggregate liquidation preferences across all preferred series, including participation rights if the preferred is participating preferred.
  • Whether any series carries a participating preferred structure, which means preferred holders collect their liquidation preference and then share pro-rata with common on the remainder — further compressing common economics.
  • Any pay-to-play provisions that could force existing preferred holders to invest in the down round or convert to common.
  • Outstanding warrants, options, and convertible notes that would expand the fully diluted share count in a new financing.
  • Any seniority changes introduced in the most recent round — some late-stage companies issued 2x or 3x liquidation preference multiples.

Incorporating the scenario into your bid decision

After running the numbers, you have a range of outcomes across scenarios. The question then is not whether you are comfortable with the upside — you probably are, or you would not be looking at the deal. The question is whether the downside scenario is survivable given your portfolio sizing.

If a 40% down-round scenario produces a near-zero recovery on your position, the position size matters enormously. A $25,000 allocation in a diversified private portfolio has a different risk profile than a $500,000 concentrated bet. The scenario analysis should feed directly into your position sizing, not just your go/no-go decision.

It also shapes the price you are willing to pay. If the seller is asking at the last-round price, and your down-round scenario shows the preference stack consuming most of the equity value at a realistic markdown, that gap is your negotiating range. Secondary prices are not fixed — they are discovered through bids and asks, and a well-informed buyer who has done this work enters negotiations from a stronger position.

Where Limen Markets fits into this process

We make the market-level inputs available at the point of indication. Our listings display the implied per-share or per-unit price, the vehicle structure (direct or SPV), and the issuer name so you can cross-reference our pricing against publicly available round data. Because supply on our marketplace is confirmed before you see it, you are not modeling a hypothetical trade — you are evaluating a real position at a specific price.

Down-round modeling is not pessimism. It is how experienced private-market investors protect themselves from anchoring too hard to a headline valuation. Run the scenario before you sign — not after.
