Rocket Lab USA (ticker: RKLB) completed its SPAC merger with Vector Acquisition Corporation in August 2021 and has traded on Nasdaq ever since. So why does it still appear on pre-IPO secondary platforms, including Limen Markets? The answer lies in structure, not status.

In a private market marketplace, many early Rocket Lab employees, seed investors, and early-stage funds held their economic interest through special purpose vehicles — SPVs — that were formed years before the merger closed. If you're still building foundational context on how pre-IPO investing structures persist through and beyond liquidity events, review the complete guide to pre-IPO investing before evaluating post-SPAC secondary listings. Those SPVs can persist well after a liquidity event if the managing entity has not yet wound them down, the underlying shares remain in a transfer-restricted period, or the fund holding the vehicle is still within its investment term.

Why post-IPO interests still trade on secondary platforms

When a company goes public through a SPAC, direct listing, or traditional IPO, most individual shareholders gain the ability to sell directly on the open market. But holders inside an SPV typically cannot. They own a membership interest in a limited liability company, not shares of the public stock directly. To convert their economic interest into publicly tradeable stock they must wait for the SPV manager to distribute shares — or sell the SPV interest itself to another party on the secondary market.

Lock-up agreements add another layer. SPAC mergers commonly impose 180-day lock-ups on founders and major pre-IPO holders. Some carry earn-out provisions tied to price thresholds that extend the restriction further. If the underlying shares are locked, the SPV interest tied to them is equally illiquid on the public market, even if the stock itself is quoted daily.

Lastly, some funds are simply slow to wind down. A venture fund that invested in Rocket Lab in 2018 may still be within its 10-year fund life, meaning it has no obligation to distribute shares to LPs until it chooses to — or until LPs seek liquidity through the secondary market themselves.

Holding an SPV interest in a public company is not the same as holding the stock. The path to liquidity is structurally different, and pricing should reflect that gap.

The key question: what is the discount to NAV, and is it justified?

Because Rocket Lab trades publicly, pricing its secondary SPV interests should, in theory, be more straightforward than pricing an interest in a purely private company. The public market provides a continuous reference point — net asset value (NAV) is anchored to the stock price. In practice, secondary interests in Rocket Lab SPVs often trade at a discount to that NAV for several structural reasons.

  • Timing uncertainty: the buyer does not know exactly when the SPV will wind down and distribute shares, introducing a present-value discount on the wait.
  • Fee drag: the SPV vehicle may carry ongoing management fees or, less commonly, residual carry on any upside above a previous preferred return threshold.
  • Transfer complexity: even for a public company, transferring SPV membership interests requires legal documentation, counterparty approval, and in some cases ROFR (right of first refusal) clearance from the managing entity.
  • Liquidity asymmetry: the buyer acquires an illiquid contract; the seller extracts immediate cash. That asymmetry commands a discount.

Before bidding on any Rocket Lab secondary interest, a buyer should ask the platform or broker: what is the expected distribution timeline for this specific SPV, are any remaining lock-ups in force, and what fees does the vehicle carry? These are not hypothetical questions — they have concrete answers that directly affect what the interest is worth today.

How to read the discount

A 5–10% discount to NAV on a near-term distribution may be reasonable compensation for legal friction and settlement time. A 20–30% discount on an interest where the fund has no clear wind-down timeline is a different calculation entirely. Neither is automatically a bad deal — it depends on what else the buyer could do with that capital and over what horizon.

One useful comparison: short-dated closed-end funds that trade at persistent discounts to their NAV. Academic work on closed-end fund discounts suggests they reflect a combination of manager quality uncertainty, redemption friction, and investor sentiment — all of which apply to post-IPO SPV interests as well.

Rocket Lab's business context and what it means for secondary buyers

Rocket Lab operates in two segments: Launch Services (the Electron rocket, with Neutron in development) and Space Systems (spacecraft components, software, and mission services). Its revenue mix is shifting toward the higher-margin Space Systems segment, which has drawn renewed institutional interest in the public stock.

For secondary buyers of SPV interests, the public stock's volatility matters directly. Because the NAV reference point moves with RKLB's share price, a buyer who locks in a secondary purchase at a given discount is implicitly taking on equity risk in a publicly traded aerospace and defense company — one that has historically shown wide trading ranges. This is not a stable-NAV vehicle.

That said, secondary SPV interests in Rocket Lab are not priced as a pure proxy for the stock. Market color from recent secondary transactions suggests that motivated sellers — LPs seeking liquidity before a fund's natural expiration — have at times accepted discounts wider than what the structural frictions alone would imply. Patient buyers who understand the mechanics have found that gap worth exploring.

Due diligence checklist before bidding

SPV wind-down timeline
Ask for the fund's stated termination date or any extensions already granted. Compare to current RKLB share price trajectory.
Lock-up status
Confirm whether the underlying shares held by the SPV remain subject to any contractual transfer restriction. SPAC-era lock-ups should have expired by now, but fund-level restrictions may persist.
Fee structure
Identify any remaining management fees or carry provisions inside the vehicle. These reduce your effective NAV even if the headline discount looks attractive.
ROFR rights
Determine whether the SPV's operating agreement grants the managing entity or other investors a right of first refusal on membership interest transfers. A ROFR can add weeks to settlement or, in rare cases, pull the deal entirely.
Tax treatment of distributions
Understand whether a share distribution from the SPV will trigger a taxable event at the SPV level versus a non-taxable distribution of stock. This is a question for a qualified tax advisor, not the platform.
Settlement mechanics
Confirm how the interest will be transferred, what documents are required, and the expected timeline from signed term sheet to closed transfer.

Where to go from here

Rocket Lab secondary interests occupy an unusual niche: public company exposure wrapped in private market structure. That combination creates pricing complexity that many buyers skip over — and that rewards those who do the structural work.

Limen Markets lists Rocket Lab among its 28 issuers. Listings refresh hourly, and confirmed seller-side supply is verified at the moment of your indication — you will not spend time on an offer that has already been pulled. Minimum ticket size is $25,000 per name.
