3 ASX Penny Stocks with market cap A$100M Poised for Growth in 2025

The Australian stock market has been navigating significant volatility, influenced by global economic shifts, commodity price fluctuations, and evolving investor sentiment. While blue-chip stocks often dominate discussions, savvy investors recognize that ASX-listed penny stocks can offer compelling opportunities—especially when backed by strong financials and growth potential.
Though the term “penny stock” traditionally refers to low-priced shares, many companies in this category boast market capitalizations exceeding A$100 million, positioning them as emerging players with room to expand. Here’s a look at three such ASX-listed stocks that could present exciting prospects for investors in 2025.
Â
1. American Rare Earths (ASX:ARR)
Market Cap: A$146.96M
American Rare Earths Limited focuses on the exploration and development of critical mineral resources, with a primary emphasis on rare earth elements—a sector vital to global technological advancements. The company’s flagship Halleck Creek Rare Earth Project in Wyoming has seen a major resource update, estimating 2.63 billion tonnes at 3,292 ppm TREO (Total Rare Earth Oxides). This positions it as one of the most substantial rare earth deposits in North America.
A key advantage for ARR lies in its Wyoming location, which offers streamlined permitting processes and cost-efficient open-pit mining potential. While the company is pre-revenue, ongoing metallurgical studies aim to optimize processing techniques, potentially improving its long-term economics. Investors looking for exposure to the surging demand for rare earth materials may find ARR an intriguing prospect.

2. Bisalloy Steel Group (ASX:BIS)
Market Cap: A$156.17M
Bisalloy Steel Group Limited is a leader in the production of high-strength, abrasion-resistant steel plates, serving markets in Australia, Indonesia, Thailand, and beyond. With a strong financial position, the company has demonstrated consistent earnings growth and prudent debt management.
For the half-year ending December 31, 2024, Bisalloy reported A$70.94 million in sales and net income of A$8.73 million, marking steady progress from the previous year. The company has significantly reduced its debt, boasting a low debt-to-equity ratio of just 3.6%, while maintaining a return on equity (ROE) of 21.7%—a strong indicator of efficient profit generation. With high-quality earnings backed by robust cash flow coverage, BIS presents itself as a resilient and well-managed industrial stock.

3. GreenX Metals (ASX:GRX)
Market Cap: A$218.31M
GreenX Metals Limited is an exploration company engaged in evaluating mineral properties across Greenland, Poland, and Germany. While still in the early stages, the company holds promising potential in the mining sector, particularly in critical minerals.
Despite being unprofitable with a negative ROE of -30.06%, GreenX Metals has successfully maintained financial stability, remaining debt-free over the past five years. The company’s short-term assets of A$7.4 million comfortably exceed both short-term (A$1.8 million) and long-term liabilities (A$277.4K), ensuring operational flexibility. Backed by an experienced management team averaging 11.8 years in tenure, GRX continues to explore opportunities for expansion within the mineral exploration industry.
