# Series D

A Series D is a late-stage venture round — the fourth priced round after seed — raised by a company that is large enough to be preparing for an exit but not yet ready for one, or that needs more capital than the plan at its Series C assumed. It is led by growth funds, crossover investors and sometimes strategic buyers, priced close to public-market comparables, and it is the round where a down round is most visible.

**Also known as:** Series D round, Late-stage round

## Key facts

- **Used at:** companies at $50m–500m of revenue, two to four years from an IPO or a sale, or ones whose last plan ran out of money before its milestones arrived
- **Binding:** yes — a further class of preferred shares, often with terms that later rounds and an IPO will have to unwind
- **Typical size:** $50m–300m; in fintech, larger when the round funds a balance sheet
- **Typical investors:** growth-equity funds, crossover funds that also buy public stocks, sovereign funds, and strategics buying an option on the company
- **Parties:** the new lead, every earlier investor deciding whether to follow, founders who by now hold a minority, and a board that is mostly investors

## How a Series D works in practice

By the fourth round a company has a track record, public comparables and a cap table with several classes of preferred stock, and the round is priced like a private placement of a near-public company. Crossover investors value it against listed peers' revenue multiples less a discount for illiquidity; the plan is an IPO or a sale within a defined window, and the terms often say so — a ratchet that gives the D investors more shares if the IPO prices below their entry, or a redemption right if no exit has come by a date.

The round is also where the market's weather shows. In 2021 fintech Series Ds were priced at multiples that the 2022 rate rises removed; Klarna, which had raised at a $45.6bn valuation in June 2021, raised $800m in July 2022 at $6.7bn. A down round triggers the anti-dilution protection of every earlier class, shifts ownership from founders and employees to investors, and often comes with a recapitalisation that simplifies the preference stack so that the company can be sold at all.

For a strategic acquirer, a Series D is sometimes the first move: an investment with information rights and a right of first refusal, so that when the company is sold the strategic knows first. For everyone else it is the round that decides whether the exit will be a listing, a sale, or a long wait.

## Example

A lending fintech with $120m of revenue raised its Series C at a $1.5bn post-money in 2021. In 2023 it needs $150m to fund growth and its lending book, and the best offer is a Series D at $900m pre-money: a down round. The Series C's full-ratchet anti-dilution protection reprices its $200m investment from $1.5bn to $900m, issuing it a further 8% of the company; the founders' stake falls from 22% to 15% and the employee pool loses proportionately. The new lead, a growth fund, takes 14% for its $150m and a 1.5× preference senior to everything before it. Two years later the company is sold for $1.4bn: the D takes $225m first, the earlier preferences $520m next, and the founders' 15% of what is left is about $98m — less than their 22% of the C valuation would have implied, and more than the zero a failed round would have produced.

## Common mistakes

- Raising a D at a flat or down valuation without renegotiating the preference stack, so the company becomes unsellable.
- Accepting an IPO ratchet without modelling what it does to earlier holders if the listing prices low.
- A redemption right the company could never fund.
- Founders and employees learning what full-ratchet anti-dilution means at the round that triggers it.
- Taking a strategic's money without noticing that its right of first refusal will chill every other bidder.
