What is a tender offer?

A tender offer is a structured invitation to a defined group of shareholders to sell a portion of their shares at a fixed price during a fixed window. This guide explains how it works, who runs it, and how it differs from a one-off secondary sale.

Direct answer
A tender offer is a structured, time-bound invitation to a defined group of shareholders — most often current and former employees and select investors — to sell some or all of their shares back to the company or to one or more buyers at a fixed price. It is the most common way large private companies provide regularized partial liquidity without going public.

Direct answer

A tender offer is a structured, time-bound invitation to a defined group of shareholders — most often current and former employees and select investors — to sell some or all of their shares at a fixed price during a fixed window. In the private-company context, it is the most common way large, late-stage companies give long-tenured shareholders a path to partial liquidity without going public.

A tender offer is not the same as an employee selling shares one-off on a secondary platform. It is a structured program with a defined eligibility list, a defined price, a defined window, and (almost always) defined caps and allocation rules.

The core pieces

Every private-company tender offer has the same building blocks:

  • An issuer. The company whose shares are being tendered.
  • A buyer or buyers. Sometimes the company itself (a self-tender or buyback). More often, one or more outside investors.
  • An eligibility list. Which shareholders can participate — typically current and former employees with vested holdings, plus select existing investors.
  • A price. A single fixed price per share, often set in coordination with a recent primary financing or an updated 409A.
  • An offer window. A fixed period (commonly 20 business days, the U.S. regulatory minimum for a tender offer that triggers Rule 13e-4 / 14E) during which eligible sellers can elect to sell.
  • Caps and allocation rules. A per-seller cap (e.g., “up to 25% of vested holdings”) and an oversubscription rule (typically pro-rata) if total elections exceed the available size.

Why companies run tender offers

Late-stage private companies stay private far longer than they used to. Employees who joined a decade ago may be holding meaningful paper wealth they cannot easily access. Tender offers solve this in a controlled, company-sanctioned way:

  • Retention. Employees can take some chips off the table without leaving.
  • Cap table control. The company chooses the buyers and the price, instead of having shares trickle out through informal secondary channels.
  • Governance. A single, structured event is cleaner than dozens of bilateral transfers.
  • Optics. A successful tender offer can establish a clear price point for the company’s shares.

Who can sell

Eligibility lists vary, but typical patterns include:

  • Current employees with vested common stock or vested options
  • Former employees with vested holdings
  • Select early investors

Newer hires, unvested holdings, and recently exercised options sometimes fall outside eligibility. The official offer-to-purchase document is always authoritative.

How pricing works

Most private-company tender offers use a single fixed price set ahead of the offer window. The price is generally informed by:

  • A coordinated primary financing round
  • An updated 409A valuation
  • Recent secondary trading activity, where available
  • Negotiation with the buyer(s)

A small number of programs use auction-like or modified-Dutch mechanics to determine a clearing price. These are far less common in the private-company employee-tender context.

What happens if too many people want to sell

If aggregate elections exceed the available size, the offer is oversubscribed. Almost all private-company tender offers handle this with pro-rata allocation — every electing seller’s tendered shares are scaled down by the same factor so total accepted shares match the cap.

How it differs from other structures

  • vs a secondary sale. A one-off secondary sale is a bilateral transfer between a single seller and a single buyer, often facilitated by a marketplace. A tender offer is a structured, multi-seller program with uniform terms.
  • vs a company buyback. A buyback is a tender offer where the company itself is the buyer. Most private-company “tender offers” are third-party-funded — the company facilitates, but the buyers are outside investors.
  • vs an IPO. An IPO is a primary public offering that creates a continuous public market. A tender offer is a one-time, private liquidity event.

What sellers should know

  • The offer-to-purchase document is the binding source. Press coverage and community posts are not.
  • Tender offers create taxable events. Withholding may apply. Get advice from a qualified tax professional.
  • Cashless exercise of options into the tender is sometimes — but not always — supported.
  • Withdrawal rights typically exist throughout the offer window.

FAQs

Is a private-company tender offer the same as a public-company tender offer? No. The term comes from public M&A, but the private-company version is operationally very different — defined eligibility, single fixed price, structured caps, pro-rata allocation, and (usually) third-party buyers.

Do I have to sell? No. Tender offers are voluntary. Eligible sellers elect to participate; nothing happens to your holdings if you do not.

Can I withdraw my election? Generally yes, until the close of the offer window. The exact mechanics are spelled out in the offer documents.

Will the price match the company’s last 409A? Often it is informed by a recent or coordinated 409A, but the tender price is a separately negotiated, fixed number. Read the offer materials.
