You bought an SPV interest in a private company six months ago. The company just announced a new Series D at a valuation 40 percent above where you bought. That sounds like good news, and in many ways it is. But a new primary round also sets off a chain of mechanical changes that every secondary holder should trace through carefully before declaring victory.
The cap table shift: dilution hits everyone, SPV included
When a company issues new shares in a primary round, every existing shareholder is diluted unless they have pro-rata rights — meaning the right to participate in new rounds to maintain their ownership percentage. SPV investors, particularly those who came in through a secondary market, almost never hold pro-rata rights. The SPV's percentage ownership of the company will shrink as new shares are issued to incoming investors.
This is not unique to SPVs. Direct secondary holders face the same dilution. But the structure of an SPV adds a layer of indirection: you own an interest in a fund that owns shares, not the shares directly. The dilution happens at the company level, then flows through the SPV's ownership percentage before it reaches you.
Whether that dilution matters in dollar terms depends on how much the per-share price increased. A round that doubles the valuation while issuing ten percent new shares still leaves you better off in absolute value. But the ownership percentage at exit will be smaller than when you bought.
A new liquidation preference stack sits on top of you
Most venture-backed primary rounds issue preferred shares with a liquidation preference — typically 1x non-participating, sometimes 1x participating, occasionally more. That preference means the new investors get paid first in any exit before proceeds reach the common stack beneath them.
If the company was acquired for exactly the primary round valuation tomorrow, the new Series D investors would be made whole first. What reaches earlier preferred holders — including the shares your SPV holds — depends on where those shares sit in the waterfall. Common shares, which many employee secondary sellers hold, are last in line.
This is the mechanism behind a deceptively common outcome: the company raises at a higher headline valuation, but secondary holders who own interests in common shares see little improvement in their expected exit proceeds once the new preference stack is modeled out. The callout below captures why.
Anti-dilution provisions: will the SPV's shares be adjusted?
Anti-dilution provisions protect investors from down rounds — situations where new shares are issued at a lower price than the investor paid. There are two main flavors: full ratchet, which reprices an investor's shares to the new lower price, and weighted average, which applies a partial adjustment based on the size of the new issuance.
Whether the shares inside an SPV carry anti-dilution protection depends entirely on what class of shares the SPV holds and what the original investment documents say. Secondary buyers often inherit shares that were issued under terms set years earlier. If those shares are preferred shares originally sold with broad-based weighted-average anti-dilution, and if the company later raises a down round, the SPV's position may benefit from additional shares or a price adjustment.
In an up round — which the scenario above assumes — anti-dilution provisions do not activate. They are only triggered when the new share price is lower than the price at which the protected shares were issued. If the company raises at a higher valuation, existing anti-dilution protections become irrelevant to that round.
The 409A valuation and what it means for secondary pricing
Every primary round triggers a new 409A valuation — the independent appraisal that sets the fair market value of common shares for tax purposes. Companies are required to update their 409A within a short window after a material event, and a new funding round is the most common trigger.
The new 409A matters to secondary buyers for two reasons. First, it sets a fresh reference point for the common stock price, which affects how secondary bids and asks are calibrated. Second, it affects sellers who hold options: if they plan to exercise after the new 409A, their strike price remains the same but the fair market value of the underlying shares is now higher, which increases the ordinary income element of an NSO exercise or the spread for AMT purposes on an ISO exercise.
Secondary market prices on platforms like Limen Markets tend to reprice faster than a new 409A can be completed and published. In practice, secondary pricing is forward-looking and reflects market participants' read of the new round before the formal appraisal is done. The 409A catches up; it does not lead.
Does the SPV's operating agreement account for any of this?
The SPV operating agreement governs the relationship between you, the LP, and the general partner who manages the vehicle. That agreement defines how distributions are made, what fees the GP charges, whether there is a preferred return before carry, and how the GP exercises any voting rights on the underlying shares.
Most SPV operating agreements are silent on cap table changes at the company level — they do not promise you any protection from dilution or new liquidation preferences. Those are company-level rights, not SPV-level rights. The operating agreement is primarily a governance document for the fund itself.
What the operating agreement does control is what happens when the GP receives proceeds. If the SPV holds preferred shares that convert to common at IPO, the conversion mechanics are governed by the company's certificate of incorporation, not the SPV agreement. The SPV agreement takes over once cash flows back to the fund — allocating the proceeds between the GP and LPs according to the carry and waterfall terms written there.
Three questions to ask when a new round is announced
- What class of shares does the SPV hold, and where does that class sit in the new liquidation preference stack? A company that just added a large Series D with a 1x participating preference has created a meaningful new hurdle ahead of earlier preferred and common holders.
- How much dilution did the SPV experience, and at what price must the company exit for the new headline valuation to translate into a gain at your entry price? Run the breakeven through the waterfall, not just the total enterprise value headline.
- Has the GP communicated anything? A well-managed SPV will send LPs a brief note after any material company event. If you have not heard from the GP after a significant round, that is itself a signal worth noting about manager quality.
Understanding these mechanics before you buy — not after the next round closes — is what separates buyers who are pricing an asset from buyers who are pricing a headline.
