Is Lynas Equity Priced for Perfection?

Lynas AU000000LYC6

Lynas Rare Earths finds itself at a critical juncture. The imminent inclusion of its shares in a major Australian index is creating a technical tailwind, but this comes against a backdrop of stark valuation warnings from analysts and fresh operational headwinds at its processing facilities.

Adding to the company's challenges are recent production disruptions. Lynas has issued guidance warning of output shortfalls in the current quarter. The cause has been traced to power supply interruptions at its Kalgoorlie facility in Western Australia, which have hampered the ramp-up of processing operations.

The immediate impacts include:

• A production deficit equivalent to approximately one month's output this quarter.
• A delayed ramp-up of processing plants due to an unstable power supply.
• Reduced output of separated rare earths, which are central to the company's revenue.

These setbacks are particularly ill-timed as Lynas seeks to demonstrate consistent supply reliability to key customers in strategic markets like the United States and Japan.

Morningstar Flags a Severe Valuation Disconnect

In a newly initiated coverage report this week, research firm Morningstar delivered a sobering assessment. The analysts assigned Lynas a fair value estimate of just AUD 7.00. With the stock recently trading around AUD 12.66, this implies a potential downside of roughly 45 percent, leading Morningstar to categorically label the shares as overvalued.

The core of their argument centers on what they see as excessively optimistic rare earth price assumptions baked into the current market valuation. While Morningstar acknowledges Lynas's formidable position as the largest producer of rare earths outside of China and forecasts impressive annual EBITDA growth of 65% over the next five years, they contend the numbers don't justify the price. To support the present valuation, the analysts argue, prices for Neodymium-Praseodymium (NdPr) would need to surge to over USD 200 per kilogram—more than double their medium-term price forecast of USD 100 per kg.

Index Inclusion Sets Stage for a Clash of Forces

A significant technical event is on the horizon: Lynas is scheduled to join the S&P/ASX 50 Index on December 22, 2025. This upgrade typically triggers automatic buying from index-tracking funds and ETFs that are mandated to replicate the benchmark's composition.

In the near term, this mechanical demand could provide support for the share price or at least contribute to heightened volatility. However, this influx of passive capital may clash with selling pressure from fundamentally-driven investors who are concerned about the steep valuation. The current price action is being shaped by this tension between passive index-driven inflows and active selling based on fundamental doubts.

December 22 will serve as a litmus test, revealing which force proves dominant: the systematic demand from index funds or the skepticism rooted in financial fundamentals.
