The retailer released its half-yearly results on Monday, revealing a $305.8 million profit, pushing its shares up 7.5 per cent to a 10-day high of $82.40.
But financial analysts have questioned the company's softer sales during January and the company said it remained concerned about future earnings due to uncertainty in the retail market and the possibility of rising prices.
The firm will issue shareholders a dividend of $2.10, up by more than 23 per cent after it raised its payout ratio.
JB Hi-Fi's Australian operations represented the biggest share of the company's revenue, rising 6.3 per cent to $4.12 billion.
Continued strong demand for consumer electronics drove sales higher, chief executive Nick Wells said, with high interest in Apple iPhones, Nintendo Switch 2 consoles and games, wearable fitness trackers, and AI-enabled devices.
Online sales rose by 11.2 per cent during the period to make up 18.4 per cent of trade.
Appliance sales, led by cooking, refrigeration, laundry and robot vacuum cleaners, boosted revenue for The Good Guys by 4.1 per cent to $1.58 billion.
Sales at JB Hi-Fi's New Zealand operations also rose by 32.6 per cent to $NZ268.6 million ($A228.7 million), although sales growth at recently acquired home appliance company e&s fell by 4.6 per cent.
The results built on momentum created during the previous financial year, Mr Wells said, but the company remained concerned about retail spending trends.
"Whilst we are pleased to see sales growth continue in January in JB Hi-Fi and The Good Guys ... we remain cautious given the uncertainty in the retail market and the continued competitive activity," he said.
The company also revealed January sales for JB Hi-Fi Australia had risen by four per cent, and sales for The Good Guys were up 2.7 per cent.
The market could focus on the smaller growth, RBC Capital Markets analyst Michael Toner said, although January is typically "a seasonally softer month".
Stock shortages had played a role in slower sales, Mr Wells said, in addition to customers looking for discounts.
The price of computers could rise by March due to higher chip and memory prices, he said, but consumers were expected to budget for electronic purchases they deemed necessary.
"Tech is becoming less and less discretionary," he said.
"People are prioritising their spend on their mobile phone among other things."
The company also revealed it had opened four new JB Hi-Fi stores in Australia and closed one during the 2026 financial year, and opened three new stores and relocated one in New Zealand.
Australian retail spending rose by 4.8 per cent in December 2026 compared to the previous year, according to figures from the Australian Bureau of Statistics, but were down by 0.4 per cent compared to November.
