A down round happens when a company raises new capital at a lower valuation than its previous round. It is one of the more painful events in a startup's life, not just because it signals that growth or market conditions disappointed expectations, but because of the mechanical effect it has on everyone already holding shares or options.
Why Down Rounds Happen
A down round can happen for reasons entirely outside a company's control, such as a broad shift in investor sentiment or a repricing of an entire sector, or for company-specific reasons, such as missed growth targets or a longer path to profitability than originally expected. Either way, the new investors are only willing to pay a lower price per share than the previous round did.
Immediate Dilution for Existing Shareholders
When new shares are issued at a lower price, existing shareholders, including founders, employees, and earlier investors, get diluted more than they would in an up round of the same dollar size, because more shares have to be issued at the lower price to raise the same amount of money. This compounds with whatever dilution already happened in prior rounds, sometimes leaving founders and early employees with a meaningfully smaller stake than they expected going into the round.
Anti-Dilution Provisions Activate
Most preferred shares issued in prior rounds carry anti-dilution protection specifically designed to trigger in a down round scenario. A broad-based weighted average adjustment, the market standard, increases the number of shares those earlier investors are deemed to hold, partially offsetting the lower price of the new round, at the direct expense of common shareholders including founders and option holders. A full-ratchet provision, less common but far more aggressive, can reprice an entire earlier round as if it had been done at the new, lower price, causing a much larger dilution hit to everyone else on the cap table. Whether a term sheet carries broad-based or full-ratchet protection is exactly the kind of detail worth understanding before signing, not after a down round makes it relevant.
What Happens to Employee Options
A down round often leaves existing employee stock options with a strike price higher than the new, lower share price implied by the round, sometimes called being underwater. Underwater options carry little or no immediate value to hold, and companies sometimes respond with an option repricing, lowering the strike price to match the new valuation, or an additional grant to make up the difference, though neither is guaranteed and both come with their own tradeoffs for the company and remaining shareholders.
Liquidation Preference Stacking
Down rounds frequently come with a liquidation preference for the new investors, on top of whatever preferences already exist from earlier rounds. Because liquidation preferences get paid out before common shareholders in an exit, a company that has raised several rounds including a down round can end up with total preferences that consume a large share of even a moderately successful exit, well before founders or employees see anything.
Independent Valuations for Option Pricing
A down round typically forces the company to obtain a fresh independent valuation of its common stock, separate from the preferred price the new investors are paying, in order to set a defensible exercise price for future option grants. That independent common-stock valuation usually drops alongside the preferred price, which is part of why new option grants issued after a down round often carry a much lower strike price than grants issued before it, creating two different classes of option holders within the same company based purely on grant timing.
Bridge Financing as an Alternative
Some companies facing a likely down round instead raise a bridge round, often structured as a convertible note or SAFE rather than a new priced round, specifically to avoid setting a new, lower priced valuation until conditions improve. This defers the down round conversation rather than avoiding it entirely, since the bridge instrument will eventually convert at whatever the next priced round's valuation turns out to be, but it can buy time for the company to hit milestones that support a better price later.
Signaling Effects Beyond the Math
Beyond the mechanical dilution, a down round changes how the company is perceived by future investors, potential hires, and existing employees. It can make the next fundraise harder, since new investors will ask why the previous round priced the company higher than the market now supports. It can also affect employee retention, since equity that looked valuable on paper at the time of hire suddenly looks less certain.
Communicating a Down Round to the Team
Employees typically find out about a down round either through a direct communication from leadership or, less ideally, through rumor once cap table changes or a new valuation start circulating informally. A direct, honest explanation of what the round means for existing equity, including whether any option repricing or additional grant is being considered, tends to preserve more trust than a vague announcement that avoids the specifics. Employees who already understand the mechanics of vesting and dilution described elsewhere in this series are generally better equipped to understand what a down round does and does not change about their own position.
What Founders Can Do Ahead of a Down Round
Founders facing a likely down round benefit from modeling the dilution and anti-dilution effects in advance, communicating clearly and early with the team about what it means for existing equity, and negotiating the smallest liquidation preference and least aggressive anti-dilution terms the market will bear, rather than accepting whatever the first term sheet on the table proposes. Understanding these mechanics in advance, during the same period a company would normally be preparing its data room for a raise, gives founders more leverage to negotiate terms that protect the team's equity as much as the situation allows.
