Under-the-radar ASX small-cap stock Austin Engineering Ltd (ASX: ANG) has just capped off a very good year for its shareholders.

Austin Engineering shares closed yesterday at 52 cents. In morning trade on Friday, shares in the global, mining-focused engineering company are trading 1.3% higher at 53 cents apiece. That brings the Austin Engineering share price up 71% over 12 months.

For some context, the All Ordinaries Index (ASX: XAO) has gained 12% over this same period.

The engineering company currently has a market cap of $329 million. Shares also trade on a fully franked 2.3% trailing dividend yield.

And according to Bell Potter this small-cap ASX stock is well-placed to keep on charging higher in 2025.

ASX small-cap stock tipped to outperform again in 2025

Bell Potter believes that Austin Engineering is "undervalued" relative to its peers. The ASX small-cap stock trades on a price-to-earnings (P/E) ratio of around 10.5 times.

According to Bell Potter's Marcus Barnard (quoted by The Australian Financial Review), "features such as lower weight, ability to customise to mine requirements and fabrication proximity to client" provide Austin Engineering with its high customer retention rates, a competitive advantage over its peers and "strong" intellectual property.

"There are several companies competing in Australia," Barnard said. He noted that Austin Engineering "could potentially acquire a competitor and achieve synergies".

Bell Potter initiated a buy rating on the ASX small-cap stock with an 86 cent price target. That represents a potential upside of more than 62% from current levels.
