Convertible loan notes: the small print that can become dilution
Convertible loan notes can fund small-caps, but the small print decides whether shareholders face future dilution, debt pressure or both.
Convertible loan notes can look like a tidy funding fix for a small company. The risk is that the tidy fix can become future dilution, especially when the conversion terms are generous to the lender and hard for ordinary shareholders to see at a glance.
The Short Version
A convertible loan note is debt that can turn into shares. The company gets cash now. The lender gets interest, repayment rights and, often, the option to convert the loan into equity at a set price or discount.
For small-cap investors, the important question is not just whether the company has raised money. It is who gets the upside if the business recovers, and how much of your ownership might be diluted when the note converts.
How Convertible Loan Notes Work
A standard loan is repaid in cash. A convertible loan note can be repaid in cash or converted into shares. The exact choice depends on the terms. Some notes convert automatically at maturity. Some convert when the company raises new equity. Some convert only if the lender chooses.
The conversion price is the heart of the deal. It may be a fixed price, a discount to the next placing price, or a formula linked to the market price. A fixed conversion price can be simple. A deep discount can be more dangerous because it gives the lender more shares for the same loan amount.
Interest also matters. Interest may be paid in cash, rolled into the balance, or added to the amount that converts. If interest is rolled up, the eventual share issue can be larger than investors expect.
Why Small Companies Use Them
Small companies often use convertible loan notes when ordinary equity funding is difficult. The share price may be weak. Market appetite may be thin. Management may want to avoid a placing at a depressed price, or they may need money faster than a full fundraising allows.
In the right setting, a convertible can buy time. It can fund a drill programme, a product launch, working capital, a turnaround or a bridge to a larger transaction. That does not make it automatically bad. The danger is that the bridge can become expensive if the expected recovery does not arrive.
Investors should ask why this funding route was chosen. If the answer is timing, the note may be reasonable. If the answer is that ordinary investors would not support a placing, the note may be a sign of stress.
Where Dilution Enters
Dilution happens when new shares reduce the percentage owned by existing holders. A convertible loan note can create delayed dilution because the new shares may not exist yet. They sit in the small print until the conversion event arrives.
That delayed effect can make the share count look cleaner than it really is. A company may report one number of shares in issue today, while a note creates the right to issue many more later. The fully diluted share count is what matters.
Look for warrants too. A lender may receive warrants alongside the note, giving them another route to buy shares later. A note plus warrants can be much more dilutive than the headline loan amount suggests.
Conversion can also change control. If one lender receives a large block of shares, they may become an influential holder overnight. That can affect future votes, board pressure and the terms of later fundraisings. Dilution is not only a maths problem. It can change who has power inside the company.
For existing shareholders, the hardest cases are notes that convert at a discount to a future placing. If the next placing is already likely to be cheap, the discount makes it cheaper still for the noteholder. That may protect the lender, but it leaves ordinary holders exposed to a bigger ownership reset.
A Worked Example
Imagine a small company has 100 million shares in issue at 10p. It raises GBP 1 million through a convertible loan note. The note carries 10 percent annual interest and converts at 5p, which is a 50 percent discount to the current price.
If the loan converts after one year, the principal plus interest is GBP 1.1 million. At 5p per share, that creates 22 million new shares. Existing holders who owned 100 percent of the company before conversion now own about 82 percent, before considering any warrants or further funding.
If the conversion price floats lower because the share price falls, the dilution can be worse. That is why variable-price conversion terms deserve special attention. They can reward the lender with more shares when the company is under pressure.
Five Checks Before You Accept The Story
First, find the conversion price. If it is not obvious, slow down. Second, check whether interest is paid in cash or added to the conversion amount. Third, look for warrants, fees and security over assets. Fourth, calculate the fully diluted share count. Fifth, ask what happens if the company cannot repay in cash.
Also check who the lender is. A strategic investor may have a different motive from a short-term finance provider. A founder, supplier or long-term partner may accept terms that support the company. A specialist lender may be focused mainly on downside protection and conversion economics.
None of these checks makes the decision easy. They do stop you treating a financing announcement as good news simply because money arrived.
Read the maturity date carefully as well. A note due in six months creates a different pressure from a note due in three years. Short maturity can force a company back to the market quickly. Long maturity can leave an overhang, because investors know a future conversion may arrive even if the business performs well.
Security is another clue. If the note is secured against assets, the lender may sit ahead of ordinary shareholders if things go wrong. If it is unsecured, the lender may demand better conversion terms to compensate. Either way, the detail tells you where the risk has moved.
What This Means For You
Convertible loan notes are not automatically hostile to shareholders. Some are sensible bridges. Some are expensive rescue funding. The difference is in the terms, not the label.
As a private investor, read the announcement like a contract. Who lends the money? What do they receive? When can they convert? How many shares could be issued? What happens if the business misses its next milestone? Those questions tell you whether the funding supports shareholders or shifts value away from them.
It is also worth comparing the funding with the company’s stated plan. If management says the cash funds a clear milestone, you can monitor progress against that milestone. If the money is described vaguely as working capital, the note may simply delay the next funding problem. Delay has value, but it is not the same as a solution.
In Plain English
A convertible loan note is a loan that can become shares. It can help a small company survive or grow, but it can also dilute existing shareholders. The headline cash raised is only half the story. The conversion terms decide the real cost.
