Convertible Preference Shares for Australian Startups: How They Work

Raising capital is a big milestone for any startup. But once you move beyond bootstrapping (or friends-and-family funding), you’ll quickly realise that “getting investment” isn’t just about the amount of money coming in - it’s also about how that money comes in.

That’s where convertible preference shares often come up in Australian startup funding rounds.

Convertible preference shares are a common way for Australian startups to bring on investors while balancing two competing priorities:

• giving investors some downside protection (so they’re not taking the same risk as ordinary shareholders), and
• keeping the cap table and governance manageable so you can keep building the business.

In this guide, we’ll walk through what convertible preference shares are, how they work in practice, and what you should think about before you issue them - especially if you’re raising a seed or early-stage round in Australia.

What Are Convertible Preference Shares?

Convertible preference shares are a class of shares that generally sit “above” ordinary shares in terms of economic rights (like getting paid first on an exit), and can convert into ordinary shares if certain events happen (for example, an IPO, a major funding round, or a sale of the company).

In plain English, investors holding convertible preference shares often get:

• preference (priority rights compared to ordinary shareholders), and
• conversion (a pathway to become ordinary shareholders later, usually on pre-agreed terms).

These shares are widely used in venture capital (VC) style deals, but they also show up in angel rounds and strategic investments - particularly where investors want clearer protections than ordinary shares provide.

Preference Shares vs Ordinary Shares (Why The Difference Matters)

Most founders start with ordinary shares because they’re simple: one share, one set of rights (subject to any special voting arrangements).

Preference shares are different because they can come with additional rights or protections, such as:

• priority return of capital on a liquidation event
• anti-dilution protections (in some cases)
• enhanced voting rights or veto rights on specific matters
• dividend rights (often non-cumulative for startups, but it depends)

When you add convertible into the mix, you’re creating a structure where an investor can move from the preference “layer” into the ordinary shareholder pool, typically when the business reaches certain milestones.

Are Convertible Preference Shares The Same As Convertible Notes?

No - and it’s an important distinction.

A convertible note is usually debt that can convert into equity later (often at a discount or with a valuation cap). Convertible preference shares are equity from day one (but with preference rights and conversion mechanics).

Both can be used to fund early-stage businesses, but they can lead to very different outcomes for:

• your cap table
• your governance
• your investor rights package
• how future investors view the company

Why Do Startups Use Convertible Preference Shares?

If you’re a founder, you’ll usually consider convertible preference shares when you want to raise money but keep things commercially workable for both sides.

They can be useful when:

• investors want priority protections (especially on downside scenarios), and
• you want to avoid overly complex debt arrangements or unclear conversion outcomes.

Here are some common practical reasons Australian startups use convertible preference shares.

1) Investors Get Downside Protection Without “Taking Over” The Company

Early investors are taking a real risk. Preference rights can make the investment more palatable, especially where the startup is still proving product-market fit.

At the same time, preference shares don’t have to mean you lose control - it depends on how voting rights and reserved matters are drafted.

2) Conversion Can Align Everyone For The Next Major Milestone

Conversion mechanics can be designed to “reset” the share class structure at a major event (like a Series A raise).

For example, in some deals preference shares convert into ordinary shares automatically when a qualifying financing happens. This can simplify the cap table going forward, especially if future investors want a clean structure.

3) They Can Work Well With A Founder-Friendly Governance Setup

In many early-stage deals, the founders want to keep day-to-day decision-making efficient, while investors want visibility and protections over major decisions.

This balance is often implemented through a combination of:

• the company’s constitution and share class rights, and
• a Shareholders Agreement setting out governance, reserved matters, information rights, and transfer restrictions.

How Do Convertible Preference Shares Work In Practice?

Convertible preference shares aren’t one “standard” product. The rights attached to them can vary widely depending on the deal, the stage of your startup, and how experienced your investor is.

That said, there are some common building blocks you’ll see in term sheets and investment documents (as examples - the exact terms are always deal-specific).

Conversion Events

A conversion event is a trigger that causes preference shares to convert into ordinary shares (either automatically or at the investor’s election, depending on the terms).

Common conversion events include:

• Qualifying financing: a future funding round above a certain threshold (e.g. raising at least $X from professional investors)
• IPO: listing the company on a stock exchange
• Exit event: a trade sale or other liquidity event
• Time-based conversion: conversion after a defined period (less common, but possible)

From a founder perspective, the key is understanding when conversion happens and whether anyone has discretion about it - because that can affect voting power, exit outcomes, and negotiations in future rounds.

Conversion Ratio (How Many Ordinary Shares Do They Become?)

The conversion ratio sets out how many ordinary shares an investor receives upon conversion.

Often it’s:

• 1:1 conversion (one preference share converts to one ordinary share), or
• variable conversion based on the economics of the deal (for example, factoring in a liquidation preference or certain adjustments).

If you’re not careful, a variable conversion formula can create surprises later - particularly around dilution and effective ownership after conversion.

Liquidation Preference (What Happens On An Exit Or Wind Up?)

Liquidation preference is one of the most important features of preference shares.

It typically means that if there’s a liquidation event (like a company sale, winding up, or other events defined in your documents), the preference shareholders get paid before ordinary shareholders.

A liquidation preference might be described as:

• 1x non-participating: investor gets back their invested amount first, then converts to share in the remainder (but usually not both)
• participating: investor gets their preference amount first and also participates in the remaining proceeds as if they had converted (often considered more investor-friendly)
• multiple preference: e.g. 2x or 3x return of investment (more common in higher-risk or distressed scenarios)

Even a “simple” 1x preference can materially change founder outcomes in a modest exit. It’s worth modelling a few scenarios before you agree to it.

Dividends (Often Included, Not Always Paid)

Preference shares can carry dividend rights. In startups, these are often drafted but not practically paid (because the business reinvests cash into growth).

Still, the drafting matters - especially if dividends are:

• cumulative (they accrue over time even if not paid), or
• non-cumulative (they only apply if declared).

Cumulative dividends can stack up and affect exit distributions, so you’ll want to understand the commercial intent behind the clause.

Anti-Dilution Protections

Some preference share deals include anti-dilution protections, which adjust the conversion terms if the company later issues shares at a lower valuation (a “down round”).

These clauses can be very technical and can significantly affect founder ownership.

They’re not always included in early rounds, but if they are, it’s a good idea to get advice so you understand how they operate in real scenarios.

What Legal Documents Do You Need To Issue Convertible Preference Shares?

From an Australian legal perspective, issuing convertible preference shares isn’t just a “term sheet” exercise. You’ll usually need to update (or create) the right documents so the share class exists properly and the company can issue it validly.

Common documents include the following.

Company Constitution (Or Amendments To It)

Your constitution typically needs to allow for the creation of different share classes (and set out the rights attached to each class), or you’ll need to amend it to do so.

This is where the share class mechanics (conversion, liquidation preference, voting rights, etc.) are often embedded.

In practice, many startups upgrade or replace their constitution as part of a funding round, including adopting a purpose-built Company Constitution.

Shareholders Agreement

While the constitution deals with core company rules, a shareholders agreement often covers the practical commercial relationship between shareholders - especially around governance and exit arrangements.

For startups issuing preference shares, a Shareholders Agreement often covers:

• reserved matters (decisions requiring investor consent)
• board composition and appointment rights
• information rights and reporting
• transfer restrictions and pre-emptive rights
• drag-along and tag-along rights

This document is also where you can help keep decision-making smooth as you bring on investors.

Subscription Agreement / Share Issue Documents

You’ll usually need documents that record the investor’s subscription for shares, the issue price, conditions precedent (if any), and completion mechanics.

Depending on the round, there may also be:

• share certificates and updated registers
• ASIC notifications and corporate records
• director and shareholder resolutions

IP And Confidentiality Documents (Often Overlooked In Funding Rounds)

Investors will often expect your key business assets - especially intellectual property - to be properly owned or licensed by the company.

If you’re still building and collaborating with contractors, developers, or advisers, it’s worth tightening up your contract stack (before you’re deep into investor due diligence).

Depending on your situation, this can include:

• a Non-Disclosure Agreement for early discussions and pitch meetings, and
• proper services/contractor agreements to ensure IP is assigned to the company.

Key Commercial Points To Negotiate (From A Founder’s Perspective)

Convertible preference shares can be founder-friendly or investor-heavy - the difference is usually in the detail.

Here are some of the key points you should pay close attention to before you sign anything.

1) Liquidation Preference Terms

Ask yourself:

• Is it 1x, or more than 1x?
• Is it participating or non-participating?
• What counts as a “liquidation event”?

Even small differences in drafting can shift the exit waterfall meaningfully.

2) What Triggers Conversion (And Who Controls It)

Conversion terms can affect:

• how future rounds are negotiated
• whether investors stay in a preference position at exit
• how voting and control dynamics work post-conversion

If conversion is optional rather than automatic, clarify when and why an investor would choose to convert.

3) Voting Rights And Investor Veto Rights

Preference shareholders might have:

• votes on the same basis as ordinary shareholders, or
• separate class votes for certain matters (meaning they can block changes that affect their rights), or
• specific consent rights set out in the shareholders agreement.

It’s normal for investors to want a say in major decisions (like issuing new shares, taking on major debt, or selling the business), but you still want day-to-day operational decisions to remain efficient.

4) Anti-Dilution (If Included)

Anti-dilution clauses are often where founders agree to something without fully appreciating the future impact.

If an investor asks for anti-dilution protection, it’s worth:

• understanding the type (broad-based weighted average vs full ratchet, etc.)
• considering whether it’s appropriate for the stage
• modelling what it could do to founder ownership in a down round

5) Alignment With Your Existing Cap Table And Future Plans

Convertible preference shares don’t exist in isolation. They interact with:

• founder vesting arrangements (if any)
• employee equity plans
• future funding rounds (and what new investors will demand)
• your constitution and shareholder decision-making processes

It’s usually easier (and cheaper) to structure things well at the start than to unwind messy terms later.

Key Takeaways

• Convertible preference shares are a common way for Australian startups to raise capital while giving investors priority rights and a pathway to convert into ordinary shares later.
• They usually include negotiated terms around conversion events, liquidation preference, and sometimes dividends and anti-dilution.
• To issue preference shares properly, you’ll typically need the right corporate documents in place, including a Company Constitution and a Shareholders Agreement.
• The “headline” valuation isn’t the only thing that matters - preference share terms can materially affect outcomes on an exit and in future funding rounds.
• Before you agree to preference share terms, it’s worth checking that the structure still supports your growth plans and keeps governance workable for you as founders.
