Secondary transactions in private company equity — where an existing shareholder sells to a new investor rather than back to the company — have grown dramatically over the past decade as investors seek liquidity from pre-IPO positions and as secondary funds have proliferated. But unlike shares of a public company, private company equity is almost always "restricted securities" under federal securities law, meaning the seller cannot simply transfer it the way one transfers shares purchased on an exchange. The transfer must either be registered — which is virtually never done for a single secondary transaction — or it must qualify for a resale exemption. Understanding which exemption applies, what conditions must be met, and how the mechanics of a clean transfer actually work is essential for any participant in the private secondary market.

Why Private Company Stock Is Restricted

Securities are "restricted securities" under Rule 144(a)(3) if they were acquired directly or indirectly from the issuer, or from an affiliate of the issuer, in a transaction or chain of transactions not involving a public offering. That definition captures virtually every share of a private company ever issued: shares issued in a Section 4(a)(2) private placement, shares sold under Rule 506(b) or 506(c), shares issued as founders' equity, and shares issued as equity compensation under Rule 701. The restricted status is a property of how the shares were originally issued, not of the identity of the current holder. A secondary buyer who purchases restricted shares inherits the restriction.

The restrictive legend — typically stamped on the face of a stock certificate, or noted in the transfer agent's book-entry records — is the physical manifestation of that status. It provides notice to the holder and to subsequent transferees that the shares cannot be freely resold. A typical legend reads substantially as follows: the securities represented hereby have not been registered under the Securities Act of 1933, as amended, and may not be sold, transferred, or otherwise disposed of in the absence of an effective registration statement under such Act or an opinion of counsel that registration is not required.

The legend is not merely cosmetic. Transfer agents are instructed not to process transfers of legended securities without either evidence that the securities have been registered, or an opinion letter from counsel to the issuer (or occasionally to the seller) concluding that an exemption from registration is available for the proposed transfer.

Rule 144: The Primary Resale Exemption

Rule 144 provides the principal safe harbor for resales of restricted securities. It is a non-exclusive safe harbor — other exemptions exist — but it is the most commonly relied upon. The conditions of Rule 144 differ depending on whether the seller is an "affiliate" of the issuer, and on whether the issuer is an Exchange Act reporting company.

The Holding Period

For resales of restricted securities by any person (affiliate or non-affiliate), Rule 144 requires that the seller have held the securities for a minimum period. For reporting companies — those that file periodic reports with the SEC under the Exchange Act — the holding period is six months. For non-reporting companies — which includes virtually every private company — the holding period is one year. The holding period runs from the later of: the date the securities were acquired from the issuer or an affiliate of the issuer, or the date of payment in full of the purchase price. Tacking is permitted: a non-affiliate who purchases restricted securities from another non-affiliate who has already satisfied the holding period may tack the seller's holding period to their own.

For Rule 144 purposes, the one-year holding period for non-reporting companies means a secondary buyer of private company stock who acquired in a Rule 506 offering must hold for at least one year before relying on Rule 144 for a resale — unless they qualify under Rule 144(b)(1), discussed below.

Current Public Information

For reporting company issuers, Rule 144 requires that adequate current public information about the issuer be available — meaning the company is current in its Exchange Act reporting obligations. For non-reporting companies, this condition applies only to affiliate sellers; non-affiliate sellers who have held for the full one-year period are not subject to a current public information requirement.

Volume Limitations

Affiliate sellers (and non-affiliate sellers of reporting company stock during the six-month period following expiration of the six-month holding period) are subject to volume limitations. In any three-month period, the seller may not sell more than the greatest of: (1) 1% of the outstanding shares of the class; (2) the average weekly reported trading volume during the four calendar weeks preceding the sale; or (3) the average weekly volume of trading in the securities reported through a consolidated transaction reporting system during the four-week period. For private companies, which have no trading volume, only the 1% cap applies.

Manner of Sale

Affiliate sellers must conduct their sales through "brokers' transactions," directly with "market makers," or in "riskless principal transactions" as defined in the rule. For private company stock — which is not publicly traded — the manner of sale condition is effectively satisfied by any negotiated private transaction, since there is no public market through which the securities could be sold improperly.

Form 144 Filing

Affiliates who intend to sell more than 5,000 shares or securities with an aggregate value exceeding $50,000 in any three-month period must file a Form 144 with the SEC concurrently with placing the sell order. This filing is public and notifies the market of the intended sale. For private company transfers, Form 144 is filed when affiliates are selling — it is not required for non-affiliate secondary transactions.

Rule 144(b)(1): The Non-Affiliate Clean Exit

The most practically important provision of Rule 144 for private secondary markets is Rule 144(b)(1), which provides a streamlined path for non-affiliates of non-reporting companies. Under Rule 144(b)(1), a person who: (1) is not an affiliate of the issuer and has not been an affiliate during the preceding three months; and (2) has held the restricted securities for at least one year — may resell those securities without being subject to the volume limitations, manner of sale requirements, current public information condition, or Form 144 filing requirements. The holding period is the only condition.

This is the rule that governs most secondary transfers of private company stock by non-controlling investors who purchased in a Rule 506 offering. Once the one-year clock runs, a non-affiliate investor can sell their shares to any buyer — accredited or not, in any amount, through any means — provided they satisfy the mechanics of legend removal and comply with contractual transfer restrictions in the company's governing documents.

The Legend Removal Process

Satisfying Rule 144's conditions does not automatically remove the legend. The transfer agent will not re-issue unlegended shares or process a transfer to a new holder without instruction from the issuer authorizing the removal. The mechanics of legend removal typically work as follows:

  • Seller requests removal. The selling shareholder submits a written request to the issuer (or directly to the transfer agent, depending on the company's procedures) requesting legend removal in connection with a proposed transfer.
  • Opinion letter from issuer's counsel. The issuer's outside counsel prepares an opinion letter addressed to the transfer agent, concluding that the proposed transfer is exempt from registration — typically under Rule 144 — and that the legend may be removed. The opinion letter analyzes the holding period, the seller's affiliate status, and any other applicable conditions.
  • Transfer agent instruction. The issuer, through its counsel or directly, instructs the transfer agent to process the transfer and issue new shares (or update the book entry) without the restrictive legend.
  • New certificate or book entry. The transfer agent cancels the seller's legended shares and issues new shares to the buyer, either as a physical certificate without the legend or as a clean book-entry position.

The opinion letter is the critical document in this process. Transfer agents will not act on a seller's unilateral representation that the legend should be removed — they require instruction from the issuer's counsel. This gives the issuer effective veto power over secondary transfers, which issuers exercise through this process and through the contractual transfer restrictions in their charter documents and shareholder agreements.

Affiliate vs. Non-Affiliate: The 10% Proxy

Whether a selling shareholder is an "affiliate" of the issuer fundamentally changes the Rule 144 analysis — affiliates face volume limitations, manner of sale requirements, and Form 144 filing obligations that non-affiliates do not. Rule 144(a)(1) defines "affiliate" as a person that directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, the issuer.

"Control" is the operative concept, and it is not defined solely by share ownership percentage. The SEC has historically treated holders of 10% or more of the voting stock as presumptive affiliates for Rule 144 purposes, but that is a rebuttable presumption, not a bright line. A holder with 12% of the shares but no board seat, no management role, and no practical ability to direct the issuer's decisions may successfully argue non-affiliate status. Conversely, a holder with 8% of the shares who is also a co-founder, serves as the company's CFO, and has significant approval rights under a shareholders' agreement may well be an affiliate despite holding below 10%.

The affiliate analysis must be done by counsel at the time of the proposed transfer, not at the time of original acquisition. A person who was an affiliate when they acquired shares, but who has since departed the board and reduced their ownership below control thresholds, may be a non-affiliate by the time they seek to sell — provided three months have passed since the last date on which they were an affiliate.

Section 4(a)(7): The Accredited Investor Secondary Exemption

Rule 144 is not the only available exemption for secondary resales. Section 4(a)(7) of the Securities Act, added by the FAST Act in 2015, provides a transaction exemption (not a safe harbor) for secondary sales that meet the following conditions:

  • Each buyer is an accredited investor.
  • The seller is not the issuer or a subsidiary of the issuer.
  • Neither the seller nor anyone acting on the seller's behalf engages in any general solicitation in connection with the sale.
  • The seller is not an underwriter, and does not purchase securities from an issuer or affiliate with a view to distribution.
  • The issuer is not a blank check company, Regulation A issuer, or development stage company that has no specific business plan or has indicated its business plan is to engage in a merger or acquisition with an unidentified company.
  • The issuer has been in active business for at least 90 days prior to the sale.
  • The seller provides to the buyer certain basic information about the issuer: the issuer's name, the address of its principal offices, its most recent balance sheet and profit and loss statement, and similar information for any predecessor entity for the past two fiscal years.

Section 4(a)(7) is particularly useful as an alternative to Rule 144 when: the one-year holding period has not yet run; the seller is an affiliate subject to volume limitations; or the issuer has not been in existence long enough for the holding period to be satisfied. Unlike Rule 144, Section 4(a)(7) imposes no holding period. Its primary limitation is that all buyers must be accredited investors, and the seller must have access to and be willing to provide basic financial information about the issuer — which can be a constraint for sellers of equity in companies with tightly held information.

Securities acquired in a Section 4(a)(7) transaction remain restricted securities in the hands of the buyer, and the buyer must satisfy Rule 144 or another exemption for any subsequent resale.

Contractual Transfer Restrictions: ROFR, Co-Sale, and Lock-Up

Even a transfer that is fully compliant with federal securities law can be blocked by contractual restrictions in the company's shareholder agreement, LLC operating agreement, or stockholders' agreement. Three provisions appear with particular frequency in private company documents and routinely complicate secondary transactions:

Right of First Refusal (ROFR). Most venture-backed and closely held private companies include ROFR provisions that require a selling shareholder to first offer the shares to the company (and sometimes to existing shareholders on a pro rata basis) at the same price and terms offered by the proposed third-party buyer. A ROFR does not prevent the sale; it gives the company and its existing shareholders a right to match the third-party offer before the transfer proceeds. For secondary buyers, the ROFR means that any deal is conditionally subject to the company's exercise rights — and therefore cannot close without the ROFR period running. Typical ROFR periods are 30 to 60 days. Secondary transactions must be structured to account for this delay, including provisions addressing what happens to price and terms if the company exercises its right after the parties have negotiated deal terms.

Co-Sale Rights (Tag-Along). In many shareholder agreements, certain investors — typically preferred stockholders or major common stockholders — hold co-sale rights that allow them to "tag along" on any proposed sale by a founder or significant shareholder, selling their own shares on the same terms as the seller. If a founder seeks to sell 20% of their holdings in a secondary transaction and several investors exercise co-sale rights, the secondary buyer may end up purchasing significantly more than anticipated — or the transaction must be restructured. Secondary buyers should conduct thorough diligence on co-sale rights in the issuer's governing documents before committing to a transaction.

Lock-Up Agreements. In connection with IPO processes, founders and significant investors typically sign lock-up agreements prohibiting sales for a specified period (commonly 180 days) following the IPO. These are contractual, not statutory, and are enforced by the underwriters through the underwriting agreement. Pre-IPO secondary transactions by locked-up parties must confirm that no lock-up agreement is in effect or has been triggered.

Practical Considerations for Secondary Buyers

Secondary buyers in private company transactions face a diligence challenge that is qualitatively different from primary investment diligence. In a primary investment, the issuer is a party and has every incentive to provide information. In a secondary, the issuer is typically not a party to the transaction and has no obligation to cooperate — though its cooperation is needed for legend removal and transfer agent instructions. Key practical points:

Confirm the seller's clean title. Secondary buyers should verify that the seller is the record and beneficial owner of the shares, that the shares are fully paid, and that there are no pledges, liens, or encumbrances on the securities. Shares pledged as collateral on a loan cannot be freely transferred without the lender's consent.

Diligence the governing documents. Before signing a purchase agreement, the buyer should review the company's certificate of incorporation, bylaws, and any applicable investor rights agreement, stockholders' agreement, or right of first refusal and co-sale agreement. These documents are available from the seller and from the company on request — issuers generally must provide them to facilitate a legitimate transfer.

Price at the illiquidity discount. Private company shares trade at a discount to their intrinsic value that reflects illiquidity, restricted securities status, and uncertainty about exit timing. That discount can range from 20% to 50% or more depending on the company's stage, the maturity of its investor base, and market conditions for the sector. Secondary buyers who pay near-IPO valuations for shares in companies that are years from a liquidity event are pricing in assumptions that may not materialize.

Rep and warranty coverage. Secondary purchase agreements should include representations from the seller covering title to the shares, the absence of transfer restrictions other than those disclosed, the seller's compliance with any ROFR or co-sale obligations, and the seller's non-affiliate status (if relevant to the Rule 144 analysis). These reps shift the risk of undisclosed encumbrances back to the seller and provide a contractual basis for indemnification if a problem surfaces after closing.

Secondary markets for private equity create real value — they give early investors liquidity, allow employees to monetize vested equity without waiting for an IPO, and give secondary buyers access to established companies at a discount. But the securities law framework governing these transfers is not forgiving of shortcuts. A transfer that bypasses the legend removal process, fails to satisfy Rule 144's conditions, or ignores a ROFR clause is not just procedurally defective — it can expose both the seller and the buyer to rescission liability and regulatory scrutiny.
