Editor’s note: This is general educational information about how rights offerings and pre-emption rules work in listed equity markets. It is not investment advice. Everything below is drawn from the statutes, listing rules and regulatory notices cited at the end.
A rights offering is priced below the market, and that discount is the part investors argue about. The argument usually starts in the wrong place. The discount is not a gift and not, on its own, a verdict on the company. It is the output of a pricing decision made inside a legal structure that decides who must be offered the shares, how long they have to decide, what happens to the shares nobody takes, and what the board has to write down before it can price the issue at all. Read the structure first and the discount stops being mysterious.
The Offer Has to Go to Existing Holders First
The starting rule in company law is that new equity belongs to current owners before anyone else. Section 561 of the UK Companies Act 2006 states that a company must not allot equity securities to a person on any terms unless it has first offered each holder of ordinary shares, on the same or more favourable terms, a proportion of those securities as nearly as practicable equal to that holder’s proportion in nominal value of the ordinary share capital, and unless the acceptance period has expired or every offer has been accepted or refused. A holder who does not want the shares may renounce the right to their allotment in favour of someone else without breaching that requirement.
Exchange rules approach the same problem from the other direction, by capping issues that are not pro rata. The ASX Listing Rules restrict how many equity securities a listed entity may issue without security holder approval, and a pro rata issue is carved out of those limits: exception 1 in Listing Rule 7.2 means a qualifying pro rata issue is not subject to the placement limits in Listing Rules 7.1 and 7.1A, and the equivalent exception in Listing Rule 10.12 takes it outside the approval requirement in Listing Rule 10.11 for issues to related parties and substantial holders. ASX Guidance Note 25 explains the reasoning plainly: a pro rata issue is excluded from Listing Rule 10.11 because all security holders have an equal opportunity to participate.
The carve-out is narrower than it looks. Guidance Note 25 states that exception 1 applies only to securities taken up directly as part of a pro rata issue, and not to a person taking up all or part of the shortfall. A director who has taken up an entitlement cannot then take up shortfall securities under the exception, even where the shortfall is allocated pro rata among those who participate. The shortfall is where a pro rata offer stops being neutral between shareholders, which is why the shortfall arrangements and the identity of the underwriter matter more than the headline discount.
What the Discount Has to Clear
Two mechanical constraints sit behind the subscription price. The first is that the price after the issue is a blend, so the theoretical rights price is a function of the discount and of how many new securities are being created for every existing one. The ASX guidance notes the practical floor directly: if the theoretical rights price for the issue is less than 0.1 cents, which is the lowest price point at which securities can be traded on ASX, the issue as a practical matter has to be non-renounceable. Below that level the entitlement cannot be sold, so a holder who does not subscribe simply absorbs the dilution.
The second constraint is take-up risk. An offer priced close to the market fails if the market moves against it during the acceptance period, and a failed offer leaves the company without the capital it raised the money to obtain. That is the tension the discount resolves. It is set to survive a decline over the subscription window rather than to reward participants, and its width is a statement about how much decline the pricing committee thinks it needs to survive.
The Disclosure a Shareholder Actually Receives
In Korea the answer to what a shareholder is told, and in what language, has been changing. Large KOSPI-listed companies with assets worth KRW10 trillion or more, 111 companies as of end-2024, have since January 2024 had to file English disclosures on 26 key items, including securities issuance, within three business days of the original Korean filing with the Korea Exchange. On November 17, 2025 the Financial Services Commission, the Financial Supervisory Service and the Korea Exchange proposed a further expansion, with a comment period running from November 17 to December 8 and the rules on the issuance of securities and disclosure taking effect in the first half of 2026 alongside matching changes to the KRX KOSPI market disclosure regulations. The proposal also covers information about annual general meetings, on the reasoning that shareholder rights are only as good as the information available for exercising them.
That timetable is worth holding next to a rights offering. A foreign holder of a large Korean issuer now receives the issuance disclosure in English, but with a lag measured in business days, and the acceptance period on an equity raising is not long.
When Pre-emption Is Switched Off
Pre-emption is a default, not a fixed right. Section 571 of the Companies Act 2006 allows a company whose directors are authorised to allot shares under section 551 to resolve by special resolution that section 561 does not apply to a specified allotment, or applies with specified modifications. The resolution lapses when the underlying authorisation is revoked or expires, and it can be renewed only for a period no longer than the renewed authorisation.
The condition attached to that power is the interesting one for anyone reading a discounted issue. Such a resolution cannot be proposed unless the directors recommend it and have made a written statement setting out their reasons for the recommendation, the amount to be paid to the company for the equity securities to be allotted, and the directors’ justification of that amount. The statement must be circulated to members with the notice of meeting, or sent to every eligible member where the resolution is written. Where pre-emption is disapplied, the price and the case for it are put in writing and put to a vote.
Analysis: What the Discount Establishes and What It Does Not
A steep discount is evidence about the pricing process, not about solvency. What it reliably establishes is that the people setting the price wanted a wide margin against an adverse move during the acceptance period, and that they were prepared to accept the dilution of non-participating holders in exchange for completion certainty. What it does not establish is why. The same width is consistent with a large raise relative to an existing share count, with a volatile security, and with a thin underwriting bid, and the offer documents record the price rather than which of those produced it.
The structural questions separate those cases, and each has a documentary answer. Is the offer renounceable, so that a holder who does not subscribe can sell the entitlement rather than absorb the dilution, or is it non-renounceable, in which case the ASX guidance points to the theoretical rights price as the reason. Who takes the shortfall, given that ASX Guidance Note 25 puts shortfall take-ups outside the pro rata exception and back inside the approval regime. Was pre-emption disapplied, and if so, what did the directors write down as their justification of the amount to be paid under section 571. Was the raise disclosed in English on the same day it was disclosed in Korean, or three business days later.
A reader who works through those four questions has a description of the transaction. A reader who works only from the discount has a number that several different transactions would produce.
