Why Calibration, Not Mark-to-Market, Should Be the Main Financial Analysis for VC Fair Value

A venture investment is fundamentally a judgment about three things:

✅ The size of a potential liquidity event

✅ The probability of that liquidity event occurring

✅ The likely date of that liquidity event

In other words: the Exit.

At the time an investment is made, substantial work goes into forming those judgments.

The investment team assesses, amongst other things, the founders, technology, product, addressable market, competitive position, customer traction, financial plan and execution capability.

It considers how much additional capital the company may require, when future financing rounds might occur, how the cap table could evolve and what dilution the investor might experience.

Ultimately, all of that analysis supports an investment thesis about a possible path from today's company to an eventual liquidity event.

What Happens After the Investment?

Throughout the lifecycle of the investment, the assumptions underlying that original investment thesis are continually being tested.

The company achieves milestones, misses milestones and encounters developments that were not anticipated when the investment was made.

Revenue may be ahead of or behind plan. A product may launch successfully or be delayed. Customer adoption may exceed expectations. Technology risk may be reduced. A key executive may leave. The company may require more capital than originally anticipated.

These are not simply operational updates.

They are valuation information.

Each development potentially changes one or more of the fundamental assumptions behind the original investment.

If the technology is successfully proven, an important risk may have been removed and the probability of a successful outcome may increase.

If customer adoption is substantially behind plan, the probability of achieving the anticipated exit may decrease and the expected size of that exit may need to be reconsidered.

If development takes eighteen months longer than anticipated, the expected exit may move further into the future.

If significantly more capital is required, another financing round may be necessary, changing the expected cap table, dilution and proceeds attributable to the existing investor.

In other words, as the company progresses, new information continually changes the original assessment of:

Probability. Timing. Size.

This Is What Calibration Should Capture

At the investment date there was an observable transaction.

But behind that transaction was an investment thesis, a set of assumptions and expectations about what needed to happen for the investment to produce its anticipated return.

At each subsequent reporting date, those assumptions can be revisited against what has actually happened.

What did we expect at the time of investment?

What has actually happened?

Which milestones have been achieved, exceeded or missed?

Which risks have been reduced and which new risks have emerged?

And ultimately:

What do those developments mean for the probability, timing and size of the potential liquidity event?

This is why calibration should be at the centre of venture capital fair value.

Calibration connects what was known and assumed when the investment was priced with what is known today.

A milestone does not increase or decrease value simply because it has been achieved or missed. It matters because it changes a Market Participant's assessment of the company's potential outcomes.

The Investment Thesis and the Fair Value Thesis Should Follow the Same Logic

This raises a simple question:

If this was the economic analysis used to make the investment, why should the fundamental analysis be different when determining its fair value six or twelve months later?

At the investment date, the investor assessed the company and formed a view about its potential outcomes.

At the next reporting date, there is more information.

The logical fair value exercise is therefore to update that same analysis.

This is consistent with IPEV's emphasis on market data and Market Participant assumptions as to potential outcomes.

For a VC-type investment, a Market Participant considering the investment today would assess many of the same things the original investor assessed: the team, technology, market, traction, milestones, financing requirements, risks and potential exits.

The information has changed.

The economic logic has not.

And What About the Market?

None of this means that broader market conditions should be ignored.

They are an important part of calibration.

Interest rates may have changed. IPO markets may have strengthened or weakened.

Acquisition multiples may have fallen. Venture funding may have become more difficult to obtain.

These developments can have significant consequences for fair value.

But again, their impact should be considered through the economics of the particular investment.

A weaker market may mean an exit previously expected in five years is now expected in seven.

It may reduce the expected size of the exit.

It may require the company to undertake an additional financing round, increasing dilution.

For a company with limited runway, a difficult financing environment may even reduce the probability of reaching the next stage.

Market conditions therefore feed into probability, timing, size and dilution.

They are important inputs into calibration.

Why Not Simply Mark to Market?

The alternative is often to focus heavily on where supposedly similar companies are valued today.

Comparable-company multiples fall, and the company's valuation is marked down.

Multiples rise, and the valuation moves up.

There are circumstances where that analysis is highly relevant.

But in VC-type investments, there is a fundamental difficulty:

What exactly is a comparable company?

Two companies may operate in the same sector, have $5 million of revenue and be growing at 70%.

Yet one may have proprietary technology, exceptional founders, rapidly improving customer retention, three years of cash and a clear route to its next financing.

The other may have relatively undifferentiated technology, management problems, weak retention and six months of runway.

Their revenue multiples may make them look comparable.

Their probabilities of achieving a successful exit may be completely different.

And this is precisely why the investment team performed all of that company-specific analysis before investing in the first place.

Market Data Is Evidence, Not the Investment Thesis

Public-market multiples, comparable transactions, interest rates, financing conditions and other market information clearly matter.

But they should inform the assessment of the potential outcomes rather than replace it.

The question should not simply be:

"Where are similar companies trading today?"

It should be:

"Given everything that has changed in the company and the market since the investment was made, what would a Market Participant now assume about the probability, timing and size of the potential outcomes?"

That brings fair value back to the same economic logic that existed when the investment was originally made.

The investment thesis and the fair value thesis should follow the same logic.

And that is why, particularly for VC-type investments, calibration rather than simple mark-to-market analysis should sit at the centre of the fair value process.

A simple framework:

Milestones → Calibration → Probability / Timing / Size + Cap Table Analysis → Fair Value
