Thinking about selling restricted US shares or navigating cross border investments? Stay ahead of regulatory changes and ensure your strategy is up to date with Cockatoo’s expert insights.

Australian investors are eyeing US markets more than ever. With cross-border listings and global capital flows on the rise, understanding US securities regulations—like Rule 144—has become crucial for anyone holding or trading shares in US-listed companies. In 2026, some subtle but important shifts in the regulatory landscape make now the perfect time to brush up on what Rule 144 means for you.

What is Rule 144?

Rule 144 is a US Securities and Exchange Commission (SEC) regulation that governs the sale of ‘restricted’ and ‘control’ securities. Restricted securities are typically those acquired in unregistered, private sales from the issuing company or an affiliate. Control securities are held by affiliates of the issuing company, such as officers, directors, or large shareholders. The rule sets out the conditions under which these securities can be sold publicly, with the aim of protecting markets from sudden, large-scale share dumps that could destabilise prices.

Key requirements under Rule 144 include:

Why Rule 144 Matters for Australians

Many Australian investors and fund managers are increasingly exposed to US securities, whether through direct investments, dual-listed companies, or Employee Stock Ownership Plans (ESOPs) with US parents. Rule 144 is especially relevant if you:

In 2026, with several ASX companies seeking dual-listings on the NASDAQ or NYSE, Australian investors may find themselves holding restricted securities that are subject to Rule 144, even if they’re based locally. Failing to comply can result in blocked trades, regulatory penalties, or delays in accessing liquidity.

Example: An Australian biotech acquired by a US pharmaceutical company issues restricted shares to local founders. Those founders must now observe Rule 144’s holding and disclosure requirements before selling their stock on US markets.

2026 Policy Updates and What’s Changing

The SEC has made several updates impacting Rule 144 in recent years, with a focus on transparency and market integrity. While the core of Rule 144 remains unchanged, here’s what’s new and notable for 2026:

These updates highlight the need for robust record-keeping and proactive communication with your broker or custodian, especially if you’re planning a significant sale.

Rule 144 may seem like a niche US regulation, but as global capital markets become more interconnected, it’s increasingly relevant for Australians with cross-border portfolios. Understanding the latest compliance requirements and market practices in 2026 is key to making smart, informed decisions about your US-linked securities.
