What Is a Right of First Refusal?
A Right of First Refusal (ROFR) is a contractual right held by the company, by investors, or by both that lets the holder match any bona fide third-party offer for shares before those shares can be sold to that third party. The selling shareholder must first deliver the third-party offer to the ROFR holder, who then decides whether to exercise the right (buy the shares at the same price) or waive it (allow the sale to proceed).
ROFR clauses appear in shareholder agreements and in the company's articles of association. They typically cover all share transfers except for permitted transfers (gifts to family trusts, transfers to controlled entities, transfers on death) and exempt transactions (transfers in an IPO or qualifying exit).
The clause exists for two reasons: first, to give the company control over who sits on its cap table (preventing competitors, sanctioned individuals, or strategically problematic buyers from acquiring shares); second, to give existing investors first crack at any liquidity opportunity, preserving their proportional ownership.
ROFR vs. ROFO: The Critical Distinction
ROFR (Right of First Refusal) is triggered after the selling shareholder has received a third-party offer. The seller delivers the offer to the ROFR holder, who matches or waives. The seller must find a buyer first, then test whether the ROFR holder is willing to match.
ROFO (Right of First Offer) is the inverse: the selling shareholder must first offer the shares to the ROFO holder before approaching any third party. The ROFO holder either buys at a negotiated price or waives, after which the seller is free to shop the shares externally — usually with a price floor based on whatever the ROFO holder offered or rejected.
ROFR is more common in venture-backed startups because it is friendlier to sellers (you can establish a market price first by finding a real buyer). ROFO is more common in PE-backed companies and joint ventures because it gives the standing party first access without forcing them to make a counter-offer to an outside bidder.
The Typical ROFR Waterfall
In most venture-backed cap tables, the ROFR cascades through multiple holders in a defined order. The standard waterfall: the company exercises first (typically a 30-day window to evaluate and commit). If the company declines or only partially exercises, the right cascades to preferred investors (typically a 30-day window for them to exercise their pro-rata share of the remainder). If preferred investors decline, the remaining shares can be sold to the third party.
Each stage of the waterfall has its own notice period and execution window. Total elapsed time from offer to closing typically runs 45–75 days. Some cap tables include a "tag-along" right alongside ROFR — instead of buying the shares, existing investors can demand to sell their own shares in proportion to the third party at the same price (see the [drag-along and tag-along guide](/captable/drag-along-tag-along)).
The waterfall structure means that the third-party buyer must wait for the entire process before knowing whether they will actually receive the shares. Sophisticated secondary funds price this delay into their offers and may include break fees for sellers who pull out mid-process.
Practical Impact on Founder Secondary Sales
For founders trying to take partial liquidity by selling secondary shares, ROFR is the dominant practical constraint. The process: identify a buyer (secondary fund, strategic, late-stage growth fund), agree price and terms, sign a non-binding term sheet, then formally notify the company of the third-party offer.
The company's 30-day window begins. The board evaluates whether to exercise — usually they do not, because few companies have the cash to buy back founder shares at market price. The right then cascades to existing investors. Some preferred investors are eager (they want to increase their ownership at a known price); others decline.
After 60–75 days, the founder finally knows how many shares can be sold to the third party. If existing investors have partially exercised, the third party may walk because the deal size shrank below their threshold. Founders planning secondary sales should brief the board early, model the ROFR outcome under several scenarios, and build a buyer relationship that survives the inevitable timeline. See [secondary transactions](/captable/secondary-transactions) for the broader framework.
When ROFR Is Waived
ROFR can be waived expressly (the company and investors sign a waiver acknowledging they will not exercise) or constructively (the notice period expires without exercise). Express waivers are common in friendly secondary transactions where the company and existing investors actively support the founder's liquidity event.
Express waivers are typically requested as part of a tender offer or a coordinated secondary round. The company organises a single buyer (usually a growth-stage fund or strategic) to purchase shares from a defined pool of sellers (founders, early employees, departing executives), and the company and existing investors waive ROFR as a precondition for the tender to proceed.
The waiver process itself can take 2–4 weeks of board-level discussion and investor consent collection. Founders organising a tender should start the waiver conversation months before the planned closing. See [shareholder agreements](/captable/shareholder-agreements) for how ROFR is typically drafted and [investor rights](/captable/investor-rights) for related transfer restrictions.
