What a Down Round Actually Does to Your Cap Table, Ratchet by Ratchet

A down round is a priced financing at a lower valuation than the company's previous round, and its mechanical consequence is not just a lower share price: anti-dilution provisions in standard preferred stock automatically reprice earlier investors' conversion terms, shifting ownership from common shareholders — founders and employees — to the preferred stack without anyone writing a new check, per standard NVCA model legal documents that govern most US venture terms. On a round priced at half the prior valuation, a typical broad-based weighted-average adjustment can move two to four percentage points of ownership, per published term analyses of market deal documents. This publication explains instruments as information, not investment or legal advice.

Down rounds stopped being rare after 2021. The median pre-money valuation for US venture rounds fell for consecutive quarters through 2022-2023 from the 2021 peak, per PitchBook-NVCA Venture Monitor reporting, and repricings became common enough that the mechanics are worth knowing cold.

What triggers anti-dilution adjustment?

The trigger is issuing new shares — usually preferred — at a price below the conversion price of an existing preferred series. When that happens, the older series' conversion price adjusts downward, meaning each old preferred share converts into more common shares than before. The investor's stake grows arithmetically; nobody buys anything. The adjustment is automatic under the charter, not a negotiation reopened out of goodwill.

Two formulas dominate. Broad-based weighted average, the market standard per NVCA documents, scales the adjustment by how many new shares are issued at the low price relative to the company's size. Full ratchet, rarer and harsher, resets the old conversion price to the new round price outright — as if the earlier investor had bought at the down-round price from the start.

How different is broad-based from full ratchet in practice?

The table's last rows are why full ratchet appears mostly where the investor has leverage: bridge rounds into companies that cannot raise otherwise. Founders signing term sheets should read the anti-dilution clause before the valuation clause, because the second number is what the first one does to you.

What else does a down round reset besides price?

Option pools and liquidation preferences, mostly. A new round typically reprices the employee option pool at the low price, which helps new grants but marks existing underwater options — and companies often run a repricing program afterward, exchanging old strikes for the new fair market value, a move that requires board approval and an accounting expense. Liquidation preference stacks can also grow: a down round negotiated with participating preferred or senior preference gives the new money first claim on exit proceeds, compounding the common stockholders' position.

Employee retention is the quiet casualty. A 2021-vintage option struck at the peak is worthless-looking at a quarter of the price, and the fix — the repricing — announces the situation to the whole team at once.

How often do down rounds actually happen?

Cyclically. After the 2021 peak, the share of US venture rounds that were down rounds rose steadily through 2023, with later-stage companies hit hardest — several analyses through 2023 put down rounds at their highest share since the 2008-2009 period, per law firm deal analyses and PitchBook-NVCA Venture Monitor data. The 2008 cohort showed the lag pattern too: repricings cluster 12 to 24 months after valuations peak, because companies raise on the old mark until the money runs out.

Is a down round worse than the alternatives?

Not automatically. The honest alternatives list is short: a bridge round that defers the repricing while spending runway, an aggressive cut to extend runway without new money, a sale, or shutdown. A down round reprices the company truthfully and funds it; a flat round at a stale mark, or debt that dodges the question, can cost more in the end. What the evidence supports: the mechanism is arithmetic, the ownership shift lands on common, and the stigma is pricing a real number instead of defending a stale one. What it does not support is the folk claim that down rounds predict failure — outcome data on repriced companies is mixed and sparse, and the honest line is that the question stays open.
