This ASX small cap is rocketing 10% today. Here’s why

Another earnings surprise has put Mayfield Group Holdings Ltd (ASX: MYG) back in the spotlight.

The electrical infrastructure group released an earnings update today that caught the market off guard and sent its shares higher.

At the time of writing, the Mayfield share price is up 10.48% to $3.48, extending a stunning run that has seen the stock surge more than 310% over the past year.

Let’s dive into what the company announced during mid-afternoon trade.

Earnings guidance jumps sharply

According to the release, Mayfield released its earnings guidance for the half-year ended 31 December 2025.

The company expects unaudited NPAT of approximately $4.9 million for the half. That compares with $1.98 million in NPAT for the prior corresponding period and $7.47 million for the full year ended 30 June 2025.

Mayfield is now on track to deliver close to two-thirds of last year’s full-year profit in just six months. The figures came in well ahead of the market’s expectations.

Management did not provide revenue or margin detail in today’s release, but the earnings jump suggests demand remains strong across energy infrastructure, data centres, defence installations, and industrial projects.

A stock that just keeps delivering

Today’s update builds on the stock’s strong performance over the past year.

Mayfield shares were trading below $1 a year ago. Since then, improvements in earnings visibility, strong order flow, and consistent execution have driven a sharp increase in investor confidence.

The company designs, manufactures, and services critical electrical infrastructure, including switchboards, modular electrical rooms, and power systems. That exposure positions Mayfield directly in the path of Australia’s expanding energy transition, data centre build-out, and defence spending.

Importantly, much of this demand is non-discretionary. Power infrastructure still needs to be built and maintained regardless of economic conditions.

Brokers remain bullish

Broker sentiment has also played a role in today’s move.

According to market reports released this morning, Bell Potter lifted its price target on Mayfield to $3.60 per share, reflecting improved earnings expectations following the guidance update.

That target implies there may still be upside from current levels, even after the stock’s extraordinary run.

Earlier broker commentary has highlighted Mayfield’s scalable operating model, strong balance sheet, and ability to convert revenue growth into profits.

What’s next?

Despite the strong run over the past year, today’s update indicates the business continues to perform well.

The company is due to release its full half-year results next month. That update should include more detail on margins, cash flow, and order books.
