Auction Technology Group PLC, up 8.8% at 339.50 pence, 12-month range 658.00p-288.00p. The London-based auction market operator expects revenue and adjusted earnings before interest, tax, depreciation and amortisation for the 12 months to the end of September to be in line with recently revised market expectations. It says the consensus has revenue at $186.3 million and adjusted Ebitda at $75.8 million. It sees an adjusted Ebitda margin of between 42% and 43%. The firm says revenue growth accelerated in the second half, and therefore it expects revenue, including Chairish, to be up around 9%. It says initial trading for Chairish has been in line with its expectations. Auction Technology says it expects its performance in the new financial year to be in line with current market expectations.

SMALL-CAP - LOSERS
----------
Resolute Mining Ltd, down 12% at 1.01p, 12-month range 1.22p-0.34p. The Africa-focused gold miner says gold production in the third quarter to the end of September was down at 59,857 ounces from 75,962 ounces in the second quarter. The firm says the lower output was due to the first full quarter of stockpile processing at Mako and the impact of rainy season on both sites. All-in sustaining costs were higher at $2,205 per ounce from $1,668 in the second quarter. Resolute says this is due to the combined impact of lower gold production and increased government royalties on higher realised gold prices. Quarterly gold sales were 53,843 ounces at an average realised price of $3,404 per ounce, compared to 80,797 ounces at $3,261 per ounce in the second quarter. The firm trims its 2025 gold output guidance to between 275,000 and 285,000 ounces from between 275,000 and 300,000. ‘2025 continues to be a transformational year across the business as we optimise our producing assets and execute on building a diverse Africa-focused gold producer,’ says CEO Chris Eger. ‘Moving into final quarter of 2025, I am confident of a stable end to the year and that the company is well-positioned for positive performance in 2026.’
