Reverse stock splits are making headlines on the ASX in 2025, as more companies turn to this strategic tool to reshape their share structure and attract new investment. While the concept might sound like financial jargon, its impact on your portfolio could be significant—especially with fresh regulatory changes coming into effect this year.
At its core, a reverse stock split reduces the number of a company’s outstanding shares while increasing the share price proportionally. For example, in a 1-for-10 reverse split, every 10 existing shares are consolidated into one new share. If you held 1,000 shares at $0.20 each, you’d end up with 100 shares at $2.00 each. The total value of your investment remains the same—at least on paper.
In Australia, reverse stock splits (often called consolidations) are governed by ASX Listing Rules and must be approved by shareholders. In 2025, updates to these rules have streamlined the process, making it easier for companies to execute consolidations swiftly and with fewer administrative hurdles.
This year has seen a surge in reverse stock splits across sectors like tech, mining, and biotech. Several factors are driving the trend:
Real-world example: In February 2025, Australian biotech firm Cellinex announced a 1-for-20 reverse split after its share price slipped below $0.15. The move allowed Cellinex to stay on the ASX and negotiate a fresh capital raising with overseas investors, illustrating the strategic flexibility a split can provide.
While a reverse stock split doesn’t change the underlying value of your investment, it can be a red flag—or a turning point. Here’s what to consider before reacting:
For those holding exchange-traded funds (ETFs) or managed funds, reverse splits of underlying holdings are typically handled behind the scenes and reflected in unit prices, with little to no disruption for investors.
Reverse stock splits can be a pragmatic move for ASX-listed companies under regulatory or market pressure, especially in 2025’s tighter compliance landscape. For investors, the key is to look past the optics—understand why the split is happening, assess the company’s long-term prospects, and monitor any changes in liquidity or trading conditions.
As always, staying informed and proactive is the best defence. Keep an eye on company announcements, review your portfolio, and don’t let a consolidation catch you by surprise.
