SaaS Exit Waterfall: How Proceeds Are Distributed When You Sell Your Company

SaaS exit waterfall mechanics showing liquidation preference distribution

The Mechanics of Liquidation Preferences: Senior to Junior

When a SaaS company exits, the proceeds are distributed in reverse order of share class seniority, not ownership percentage. Series B preferred shares are senior to Series A preferred shares, which are senior to common shares (founder and employee shares). The typical process is: Series B investors receive their preference first, then Series A investors, then founders. This is codified in the articles of association and indenture agreements signed at each funding round. Most founders never read these documents carefully. This is a critical mistake.

Liquidation preferences come in two forms: non-participating and participating. Non-participating means investors receive the greater of their preference amount or their pro-rata share of remaining proceeds. This is the market standard and is founder-friendly. Participating means investors receive their preference first, then participate pro-rata in all remaining proceeds as if they were common shareholders. This is aggressive and typically only negotiated in down-rounds or by experienced investors in late-stage rounds. Understanding which type you negotiated at each round is essential to waterfall modelling.

The £10M Exit Scenario: How a Small Acquisition Distributes

Let us model a realistic £10M exit for a company with the following cap table: founders own 35% (common shares), Series A investors own 30% (1x non-participating preferred), and Series B investors own 25% (1x non-participating preferred). The remaining 10% is employee options. Assume Series A has a £5M post-money valuation and Series B has a £20M post-money valuation. Founders bought in at £0.50 per share (seed valuation), Series A at £2.50 per share (£5M post-money), and Series B at £5 per share (£20M post-money).

The waterfall at £10M exit proceeds as follows: first, Series B investors receive 1x their liquidation preference. They invested at £20M post-money, meaning they own £20M of equity. With 1x non-participating preference, they receive £20M or their pro-rata share of £10M (25%), whichever is greater. Since £20M exceeds £10M, the entire exit is distributed to Series B investors. Founders and Series A investors receive zero. This is why down-side protection matters more than ownership percentage. Series B has 25% ownership but receives 100% of the proceeds because their liquidation preference is senior to all other share classes.

The £30M Exit Scenario: Where Preference Gets Exhausted

Now assume the same company exits at £30M. Series B investors again have a 1x non-participating preference based on their £20M post-money valuation. They receive min(£20M, 25% of £30M) or max of the two values. They receive max(£20M, £7.5M) = £20M. Remaining proceeds: £30M minus £20M = £10M. Series A investors have a 1x preference based on their £5M post-money valuation. They receive max(£5M, 30% of remaining £10M) = max(£5M, £3M) = £5M. Remaining proceeds: £10M minus £5M = £5M. Founders now participate pro-rata in the remaining £5M. With 35% ownership of the common pool, founders receive 35% of £5M = £1.75M.

The full distribution is: Series B £20M, Series A £5M, founders £1.75M. Series B still receives 67% of proceeds despite owning 25% of the company. This is the leverage of liquidation preferences. Series A receives its preference fully covered. Founders receive the crumbs. This outcome is why founders negotiate aggressively on valuation and preference terms at each round.

The £80M Exit Scenario: Founders Get Paid

Finally, assume the same company exits at £80M. Series B receives max(£20M, 25% of £80M) = max(£20M, £20M) = £20M. Remaining: £60M. Series A receives max(£5M, 30% of £60M) = max(£5M, £18M) = £18M. Remaining: £42M. Founders receive 35% of the remaining common pool = 35% of £42M = £14.7M. The distribution is: Series B £20M (25%), Series A £18M (22.5%), founders £14.7M (18.4%), employees £27.3M (34.1% for option holders).

Observe that in this scenario, everyone is paid above their preference, and the remaining proceeds distribute pro-rata by ownership. Founders finally capture meaningful value. This is the upside case investors promise: if the company succeeds massively, everyone gets rich. The tension between Series A and Series B is that their preferences conflict. Series A wants the exit at £15-30M because their preference is exhausted there and they participate pro-rata. Series B wants exits above £30M because they capture all upside. Founders want exits above £50M because their ownership captures most value.

The Crossover Point: Where Founders Prefer Conversion

In most SaaS term sheets, preferred shareholders have conversion rights at IPO or earlier if specified. Conversion means preferred shares convert to common shares, eliminating liquidation preferences. This usually happens at IPO because investors cannot maintain preferences in public companies (regulators require equal treatment). Before that point, conversion is optional and rarely used.

The crossover point is the exit price where founders become indifferent between the waterfall (where preferences apply) and a pro-rata distribution (where everyone is treated equally by ownership percentage). This calculation reveals when investor interests and founder interests align or diverge. If Series B invested at a £20M post-money valuation with 1x preference, their effective downside protection is that they get £20M before anyone else. The crossover point for Series A is when pro-rata distribution equals their preference payout. For Series A with 30% ownership and £5M preference, the crossover is when 30% of total proceeds equals £5M, meaning total proceeds equal £16.7M. Below £16.7M, Series A prefers the waterfall. Above £16.7M, Series A prefers conversion and pro-rata treatment.

Founders should calculate this crossover for each investor class. If the crossover is at £200M (a high-growth scenario), then investors have strong incentive to push for growth and won't push for an early exit. If the crossover is at £15M and the company is growing at 30% annually, investors may push for an exit at £20M where their preference is exhausted and they participate pro-rata, even though founders would prefer to keep building.

Modelling Waterfalls in a Spreadsheet

Building a waterfall model is straightforward. Create a spreadsheet with columns for each shareholder: Series B, Series A, common shares (founders), and employees. For each shareholder, record the post-money valuation they invested at, their ownership percentage, and their preference type. Then, create scenario columns for different exit prices: £5M, £10M, £20M, £40M, £80M, etc. For each scenario, calculate the waterfall: first, pay Series B their preference or pro-rata share (whichever is greater). Then, pay Series A their preference or pro-rata share of remaining proceeds. Finally, distribute remaining proceeds to common shareholders by ownership percentage. The model will immediately show you which exit prices favour which shareholders. Most founders are shocked by how high an exit must be before they capture meaningful value. Use this shock as motivation to negotiate lower valuations or lower preferences at each round.

Key Negotiation Points on Liquidation Preferences

When negotiating Series A or B term sheets, focus on three variables: the preference multiple (1x vs 1.25x vs 2x), whether it is participating or non-participating, and the definition of liquidation (does a major customer acquisition count, or only cash exits). Market standard is 1x non-participating, meaning investors receive back their invested amount before any common shareholder gets paid. This is reasonable. Do not accept participating preferences unless you are desperate and the investor is taking genuine risk (down-round). Do not accept preferences higher than 1x unless the round is very difficult. Each 0.25x increase in preference multiplier moves the crossover point materially. The difference between 1x and 1.25x at a £10M round is that 1.25x investors receive £12.5M of preferences instead of £10M. At a £25M exit, this means founders receive an extra £2.5M because the second investor's preference doesn't completely exhaust proceeds.

Escrowed and Contingent Proceeds

Most SaaS acquisitions include purchase price adjustments, earnouts, and escrow holdbacks. These funds are not available at close and therefore don't factor into the immediate waterfall distribution. A £50M acquisition with £40M at close and £10M in earnout contingent on performance means only £40M goes into the waterfall initially. The earnout distributions happen later, typically over 12-24 months. This is materially important because founders frequently assume the full acquisition price is available at close. It is not. Model the earnout scenarios. Optimistic, realistic, and pessimistic scenarios for achieving earnout milestones. Assign probabilities to each. Calculate the expected value of your founder payout including the earnout probability discount. Most founders would take a £40M certain acquisition over a £50M acquisition with a 30% probability of earnout. The expected values are £40M vs £35M.
