In brief

  • To the dismay of a chunk of its shareholders, James Hardie’s US$8.75 billion cash and scrip acquisition of Azek, which will see James Hardie shares diluted by the issuance of 35% more of its issued capital, does not require shareholder approval.
  • ASX granted James Hardie a waiver from the requirement for a listed entity to obtain shareholder approval before exceeding its 15% placement capacity in line with its published guidance that gives a US law merger the same treatment as if it were an acquisition by an Australian takeover or scheme of arrangement.
  • Harking back to a similar dynamic which resulted in the reverse takeover reforms and the current requirement for shareholder approval if a listed entity would issue 100% or more of its securities as scrip consideration under an Australian scheme or takeover (which would result in a target owning 50% or more of a bidder), the ASX has proposed a review of its Listing Rules relating to such shareholder approval requirements.
  • James Hardie has diffused one of the points of shareholder concern, being the proposed transfer of James Hardie’s primary listing to the New York Stock Exchange, announcing that it will not do so without shareholder approval. 

James Hardie to merge with Azek without a vote by James Hardie shareholders

On 24 March 2025, James Hardie Industries plc, an ASX listed Irish company, announced that it had entered into a merger agreement with The Azek Company Inc., a NYSE listed US company, under which James Hardie would acquire Azek for a combination of cash and scrip for a total value of US$8.75 billion. To form the scrip consideration, James Hardie would issue shares amounting to approximately 35% of its issued capital. Azek shareholder approval is a condition to the merger, but approval of James Hardie’s shareholders will not be required.

At a high level, Listing Rule 7.1 provides that the equity securities a listed entity can issue without shareholder approval over any 12-month period is limited to 15% of the fully paid ordinary securities it had on issue at the start of that period, unless an exception applies. There is an exception for the issuance of equity securities to provide consideration under an Australian scheme or takeover, provided that, following the 2017 amendments discussed below, the number of securities issued is not greater than the number of securities the entity has on issue (ie it is not a “reverse takeover”).

The ASX granted a waiver to James Hardie which extends the scheme/takeover exception to apply to the merger on the basis that the Azek shareholder approval and merger process under US law is considered by the ASX to be sufficiently similar to an Australian scheme. The condition to the waiver is that the issue of shares under the transaction will not effect a reverse takeover. This is consistent with ASX’s published guidance, which provides that, where the ASX listed entity is to acquire a foreign entity through a mechanism that is sufficiently similar to Australia’s regime, the ASX will give a waiver so that the foreign acquisition is treated as if the scheme/takeover exception applies.

The ASX publicly released its reasons for its waiver decision. Those reasons also refer to Listing Rule 11, which provides that, if an entity is proposing to make a significant change to the nature or scale of its activities (generally 25% of relevant financial metrics), the ASX may impose a shareholder approval requirement or may require that the entity meet the requirements for admission and quotation as if it were applying for admission and quotation on the ASX for the first time. This is in effect to prevent so called ‘backdoor listings’ without proper disclosure and approvals. Listing Rule 11 also provides that shareholder approval must be obtained if an entity is disposing of its main undertaking (ie 50% change in relevant metrics). The ASX confirmed that, in following its published guidance, the only applicable consideration was whether the merger amounted to a backdoor listing of Azek on the ASX, and found that this would not be the case, as the merger would not result in a doubling of any of the specified financial metrics.

On the face of the technical position and as confirmed by the ASX, not requiring bidder shareholder approval in this situation is not out of step with the ASX’s published guidance. So why has it become such a fiercely debated topic for James Hardie shareholders and the wider financial press? The shareholder view is set out in a letter signed by 21 Australian fund managers, which, according to media reports, cites that a dilution of shares to the proposed extent and the expected shift of James Hardie’s primary listing away from the ASX to the NYSE ought to have been approved by shareholders.

Context is everything. Here the backdrop includes the announcement of what some commentators are calling an overpriced deal during a period of significant market turbulence (following imposition of new tariffs and other news), a broader trend of dwindling IPOs combined with a steady a stream of public to private M&A transactions and a transfer of a primary listing by an ASX50 company which has previously shifted itself away from Australia in circumstances where it had historic liabilities for asbestos related illnesses. 

James Hardie seemed to have listened to shareholder views, within the confines of the agreement for the merger, and confirmed around one month after the merger was announced that it would not be shifting its primary listing away from the ASX by seeking Foreign Exempt Listing status and, in any event, would hold a shareholder vote before any decision to change ASX listing status. The effect of this proposal is that, subject to any further waivers, James Hardie will have to comply with the full listing rules of both the ASX and NYSE in the meantime (as we expect that the merger would tip the number of James Hardie shares held on the NYSE to over 50%, revoking its “foreign private issuer” status for NYSE purposes). This is understood to involve added cost and governance restrictions.  

This is not the first time that shareholders have voiced concerns with a dilutionary scrip merger that did not require shareholder approval.

In 2014, Roc Oil and Horizon Oil proposed a scheme of arrangement whereby Roc Oil would acquire all issued capital in the larger Horizon Oil, resulting in Horizon Oil shareholders owning approximately 58% of Roc Oil. Horizon as the target required shareholder approval but, as the bidder, the smaller Roc Oil did not require shareholder approval even though it would essentially be taken over by Horizon Oil.

The transaction did not proceed as Roc Oil received a superior proposal. However, the shareholder outrage in response to the proposed scheme (including an activist shareholder convening a vote seeking to amend the constitution to not allow an issue of securities in excess of 30% of its existing capital without a shareholder vote, which did not pass) prompted reforms to the ASX Listing Rules such that reverse takeovers are no longer able to benefit from the scheme/takeover exception, taking effect in 2017.

ASX to review Listing Rules related to shareholder approval requirements

On 27 April 2025, the ASX responded to the public and shareholder reaction to the merger, announcing its review of the Listing Rules relating to shareholder approval requirements. This work will be an update to the ASX’s 2017 review in respect of reverse takeovers discussed above. The key question for the ASX will be whether the current threshold for shareholder approval of a scrip merger strikes the right balance between shareholders having the right to vote on transformational transactions and the importance of the ability of boards to effectively run a business, including conducting M&A where appropriate, without unnecessarily obstructive or expensive hurdles. Being required to hold a vote may disadvantage an acquirer if the seller perceives that as giving the acquirer’s shareholders a veto right, creating uncertainty for the transaction.

Perhaps ironically, James Hardie would not be able to proceed with the merger without approval of its shareholders if its primary listing were on the NYSE. In the US, the NYSE rules mandate shareholder approval for transactions or a series of related transactions which involve an issuance of 20% or more of a listed company’s shares on issue or the issuance of a number of shares equal to or greater than 20% of the voting power of the company prior to the issuance (the “20% rule”). The Nasdaq has a similar 20% rule. There are a number of exceptions and limitations in respect of the 20% rule. However, unlike in Australia, there is no exception for shares issued in connection with a merger and bidders in public M&A transactions are not generally seeking waivers and exceptions to avoid shareholder approval requirements – a shareholder vote in an acquisition where a bidder exceeds the 20% rule is a well-accepted fact of public M&A in the US. Though James Hardie does already maintain a NYSE listing, it is expected that it currently benefits from “foreign private issuer” status on the NYSE, meaning that the ASX is its primary listing, and as such is not subject to the 20% rule.

By comparison, the UK has moved further away from requiring bidder shareholder approval for transactions. Prior to reforms enacted in 2024, the position under the listing rules in the UK was that shareholder approval was required for any “significant transaction”, being any transaction outside the ordinary course of business where the size of the transaction compared to the company was greater than 25% (based on certain percentage ratios).

Under the new regime, there is no such approval requirement for transactions greater than 25% other than in the case of a reverse takeover. The new requirement for significant transactions is that the entity must announce sufficient information regarding the proposed transaction and such announcements are not subject to prior FCA approval. While the listing standards have relaxed, share issuances require shareholder approval under UK company law, with the approvals required by any company for up to one-third of issued share capital (and a second third for a fully pre-emptive issue) routinely subject to resolutions at each AGM (in accordance with institutional investor guidelines). 

Way forward for the ASX

The policy justification for relaxing shareholder approval requirements in the UK, being to increase the attractiveness and competitiveness of the UK’s public markets and make UK-listed companies more competitive in M&A situations (recognising they’ve come from a stricter regime), would be equally applicable to Australian markets when considering any reforms to the Listing Rules going forward. Before changes are proposed, it should also be considered whether the investor reaction to James Hardie’s proposed acquisition and listing transfer came as such a surprise because the current regime is generally accepted and applied without incident.

However, there is a balance to be struck and recognising in other jurisdictions the scale of issuance permitted without shareholder approval is lower (either at law, listing rules, institutional investor guidelines or by custom), if the largest investors in Australian public markets equities consistently have a shared view that the point at which listed company boards need to seek approval for acquisitions paid for in their own scrip is lower than current settings, then it is necessary to go through that process. 

We expect any reforms will be subject to a detailed consultation process. In an age of increasing shareholder activism, in the meantime more Boards will need to assess whether it is appropriate to voluntarily seek shareholder approval for an acquisition paid in scrip, similar to when BHP decided to seek approval despite its dividend demerger of South 32 not requiring shareholder approval at law or under the applicable listing rules.
