What is a secondary fund in private equity — and when it belongs on a buyer list

Secondary funds are a distinct category within the private equity universe, and they appear regularly in PE databases alongside buyout, growth equity and credit firms. For a sell-side adviser or founder building a sponsor list, recognising a secondary fund early — before sector, geography or deal size are even considered — prevents approaches that cannot result in a transaction.

The defining feature of a secondary fund is its counterparty. A buyout or growth equity fund negotiates with the owner of an operating company — a founder, a family, or a corporate divestitures team. A secondary fund negotiates with the owner of an existing PE fund stake — a pension fund, an endowment, a sovereign wealth fund, or a PE manager moving assets between vehicles. The two types of transaction involve different sellers, different legal structures and different return mechanics.

What a secondary fund does

Secondary investing is the practice of acquiring existing stakes in private equity funds or PE-owned assets rather than committing capital to new primary fund investments. When an institutional investor committed to a PE fund ten years ago now wants liquidity, it can sell its stake to a secondary fund rather than waiting for the primary fund to complete its remaining exits. The secondary buyer steps into the original investor’s position: it assumes the remaining capital call obligations and receives a proportionate share of future distributions.

The price is typically negotiated at a discount or premium to the most recent net asset value of the underlying portfolio, depending on fund performance, remaining life and the quality of the underlying assets. The secondary fund’s return comes from that entry discount, from any subsequent value creation in the portfolio, and from the eventual exit proceeds when the primary fund sells its remaining companies.

For an operating-company owner or a sell-side adviser running a disposal process, the mechanics matter: a secondary fund that has just acquired an LP stake in a buyout fund has not acquired any of the portfolio companies in that fund. It has acquired the right to receive a share of what those companies return when the primary fund eventually exits them. The secondary buyer’s relationship is with the primary fund’s manager, not with the portfolio companies themselves.

Three secondary strategies and what each buys

LP-led secondaries are the original and most common form. A limited partner in an existing PE fund — a pension fund, endowment or family office — sells its stake to a secondary buyer. The transaction is between two investors, with the primary fund’s manager (the GP) typically providing consent but not itself transacting. The underlying portfolio companies are unaffected; they do not receive new capital and do not gain a new operating partner.

GP-led continuation vehicles have grown significantly since 2020. In a GP-led transaction, the PE fund’s manager proposes to transfer one or more high-performing portfolio companies from a maturing fund into a new continuation vehicle. Existing limited partners can sell their stake at closing (the secondary fund provides that liquidity) or roll their interest into the new vehicle. The GP continues to manage the same companies under a new fund structure. Secondary funds specialising in GP-led transactions are providing liquidity to the exiting LPs and typically co-investing in the continuation vehicle alongside the GP.

A company held in a continuation vehicle is still PE-owned and not available for a third-party sale unless the GP decides to exit it. A GP-led secondary transaction is a financing and liquidity event for the investor base, not a change of operating ownership that creates an acquisition opportunity.

Direct secondaries (also called portfolio acquisitions or single-asset secondaries outside the GP-led context) involve buying one or more companies directly from a PE sponsor, usually as a block. The buyer acquires the portfolio companies themselves rather than a fund stake. This structure looks more like a traditional PE-to-PE sale, and the direct secondary buyer is an operating-company acquirer in this specific transaction. However, the seller is a PE fund, not a founder or business owner, and the deal is structured as a negotiated sponsor-to-sponsor transfer rather than a company sale process run by the company’s management.

Why secondary funds appear alongside buyout and growth equity firms

Secondary funds are registered investment advisers with the same regulatory status as buyout or growth equity funds. They file Form ADV with the U.S. Securities and Exchange Commission and, for UK-regulated managers, appear in the FCA Financial Services Register. A PE database that sources records from adviser registrations will include secondary funds because the regulatory category — private fund adviser or alternative investment fund manager — is the same.

The difference is at the strategy level, not the registration level. Just as private credit funds appear in PE databases because they share the same adviser registration category as equity fund managers, secondary funds appear because their legal and regulatory status is identical to that of primary PE investors.

Many large managers run both primary and secondary strategies under the same adviser registration. A single registered investment adviser may operate a buyout fund, a growth equity fund and a secondary fund — all under the same entity. For these managers, the secondary mandate is additive: the firm is also a primary PE buyer, and filtering it out entirely because it runs secondary funds would exclude it incorrectly. The relevant question is whether a specific fund run by that manager makes new primary equity investments in operating companies.

This is the same structural point that applies to firms running both equity and credit strategies: the firm’s aggregate registration is less useful than a fund-level view of which mandates are active and what each fund actually buys.

How to identify secondary strategy from public filings

For SEC-registered advisers, Form ADV Part 2A Item 8 — Methods of Analysis, Investment Strategies and Risk of Loss — describes the strategies the adviser uses. A secondary-focused firm will typically describe:

acquiring limited partnership interests in private equity funds
purchasing interests in private funds or pooled investment vehicles
secondary market transactions or secondary fund investments
providing liquidity to existing investors
continuation vehicles or GP-led restructurings
structured secondary solutions

An adviser that describes only primary equity transactions — acquiring portfolio companies, making control investments in operating businesses, providing growth capital to companies — is not operating a secondary strategy under that registration. The SEC Investment Adviser Public Disclosure system makes Form ADV filings publicly searchable.

The FCA Financial Services Register provides parallel disclosure for UK-regulated managers. Strategy descriptions in FCA register entries vary by firm; some provide detailed strategy descriptions, others describe only the types of funds managed. For secondary specialists, the fund names and descriptions often contain secondary, continuation, or liquidity as identifiers.

These filings describe declared strategy. They confirm what a firm is authorised to do and what it has told regulators about its investment activities. They do not confirm whether the firm is actively deploying secondary capital right now — that is the same current-deployment gap that affects all strategy verification, addressed in the stated criteria versus current deployment article.

What this means for a buyer list

The filter has different results depending on whether the buyer list is for a company sale or for GP/LP research.

For a company sale or capital raise by an operating business: a pure secondary fund should typically be excluded. Its capital is deployed by acquiring fund stakes or portfolio positions from other investors — it does not provide fresh equity capital to operating companies through a negotiated sale process. An approach asking a secondary-only fund to participate in an equity transaction for a company has the same structural problem as approaching a credit-only firm: the fund mandate does not permit the transaction.

The exception is a firm running direct secondaries alongside, or a large manager that runs primary funds in addition to its secondary activity. For those firms, the relevant question is whether a primary equity fund is available and what that fund’s strategy, geography and deal-size criteria are.

For placement teams mapping the LP and co-investment market: secondary funds are relevant. A placement team raising capital for a new PE fund or a co-investment opportunity can approach secondary funds as potential buyers of GP-led transactions or as participants in continuation vehicles. In this context, secondary funds are not excluded — they are a target audience.

Applying the right filter depends on knowing what the buyer list is for. The same firm can be correctly excluded from one list and correctly included on another, for different mandates at the same organisation.

What the database records and what it cannot establish

A private equity database sourcing strategy from regulatory filings will record, at the adviser or fund level, whether the stated mandate involves secondary transactions. That is the floor: a declared secondary strategy in a regulatory filing is the firm’s own account of what it does.

What the database cannot establish:

Whether the firm’s secondary activity is its primary business or a small proportion of a broader primary fund platform
Whether a firm that has historically run secondary funds continues to do so with active capital
Whether a continuation vehicle transaction creates any near-term exit or acquisition opportunity for the portfolio companies within it
Whether a firm’s GP-led activity means it is open to external company acquisition approaches

Secondary investing is an important and growing part of the private markets. For the practitioner building a sponsor list or a buyer list, the strategic question is simple: is this firm’s relevant fund mandate to deploy capital into operating companies, or to acquire existing investor positions? Answering it before filtering by sector, geography or deal size preserves the accuracy of the list before the first approach.

Frequently asked questions

What is a secondary fund in private equity?

A secondary fund acquires existing stakes in private equity funds or PE-owned assets from other investors who want liquidity before those underlying funds have wound down. The secondary buyer is purchasing a position — a share of future distributions from an existing PE portfolio — rather than committing fresh capital to a new investment thesis. Its counterpart is a primary fund, which raises capital from investors to deploy into new companies over a defined investment period.

Do secondary funds buy operating companies?

Generally no. A traditional LP-led secondary fund acquires a limited partner's existing stake in a PE fund. It is not buying the portfolio companies directly — it is buying the right to receive a share of whatever those companies eventually return when the primary fund exits them. The exception is direct secondaries, where a buyer acquires a single asset or a group of assets directly from a PE sponsor, bypassing the fund-stake structure. Even then, the seller is typically a PE firm, not a business owner or founder seeking a new equity partner.

What is a GP-led continuation vehicle?

A GP-led continuation vehicle is a transaction in which a PE fund's manager moves one or more portfolio companies from an existing, maturing fund into a new vehicle — rather than selling them in a traditional exit. Existing limited partners can sell their stake at that point (providing them liquidity) or roll into the new vehicle. Secondary funds often provide the capital that allows this transfer to happen. The underlying companies remain under the same manager's ownership; what changes is the fund wrapper that holds them and the investor base that backs that fund.

How is a secondary fund different from a primary PE fund?

A primary PE fund raises capital from investors and deploys it into companies — it is an operating-company buyer. A secondary fund raises capital and deploys it by acquiring existing PE fund stakes or PE-owned portfolios. Its investment return comes from the discount it negotiates on those stakes and the eventual performance of the underlying assets. It does not conduct proprietary deal origination for new company investments in the same sense that a buyout or growth equity fund does.

How do I identify a secondary fund from a PE database or public filing?

In SEC Form ADV Part 2A, a secondary-focused firm will typically describe its strategy in terms of acquiring limited partnership interests, purchasing interests in private funds, acquiring secondary positions, or providing liquidity to existing investors. A GP-led specialist may describe continuation vehicles, structured liquidity solutions, or GP-led transactions. The FCA Financial Services Register performs a parallel function for UK-regulated managers. The key indicator is that the investment activity described is acquiring positions from other investors rather than deploying capital into operating companies.
