The standout performer in small-cap markets this week was Quadrise PLC (AIM:QED), the AIM-listed fuel technology company whose shares surged almost 80% as investors focused on the potential scale of its commercial partnerships with some of the world's largest shipping and commodities groups.
It has developed MSAR, a technology that blends heavy residual oil with water to create a cheaper, lower-emission fuel emulsion that can replace conventional bunker fuel in large marine engines and industrial boilers, delivering meaningful cost savings without requiring significant modifications to existing equipment.
The timing could hardly be more relevant: with oil prices elevated and shipping operators facing intensifying pressure to cut both costs and emissions, a technology that can meaningfully reduce fuel bills while improving the environmental profile of a voyage has obvious commercial appeal.
The company remains pre-revenue, but Shore Capital, its house broker, struck an upbeat tone on interim results this week, pointing to continued commitment from MSC, the world's largest container shipping line, and Moroccan chemicals group OCP as the critical signals for investors.
MSC alone consumes close to 10 million tonnes of fuel oil annually, and Shore estimates Quadrise could charge around $50 per tonne for its technology, suggesting the commercial prize, even on modest adoption, could be substantial.
AIM slides, Footsie holds its nerve
Turning to the wider market, the AIM All-Share fell around 0.4% to 715, leaving it down 7% in the year to date. Its benchmark, the FTSE 100, was flat after what can best be described as a rollercoaster week for global equity markets, dominated once more by geopolitics and Iran specifically.
Sticking with the risers, Mobilityone Limited (AIM:MBO) shares jumped 405% after a long-delayed merger between its partner Super Apps and a US acquisition vehicle moved closer to completion.
The deal will trigger an £11.3 million cash payment to the UK e-commerce specialist for a 60% stake in its retail subsidiary, with a further payout contingent on hitting revenue targets. That figure is more than double MobilityOne's current market value.
SkinBioTherapeutics steadies the ship
An update on the ongoing accounting investigation at SkinBioTherapeutics PLC (AIM:SBTX, FRA:5KW) provided a tonic to investors as the company revealed its cash position to be robust, with around £2.4 million in the bank. The shares rose 45% over the week. However, they are still less than half their value just before the probe was announced.
Metals One PLC (AIM:MET1, FRA:HT7, OTCQB:MTOPF) was up 31% this week as the Vantage Goldfields deal crept closer to the finish line, with a creditor meeting now called to approve Lions Bay Resources' $40 million bid for the South African gold assets sitting on a historical resource inventory of 4.5 million ounces.
Lions Bay has already deposited $6 million, with another $4 million committed before the meeting and the remaining $30 million heading into escrow once regulators give their blessing. When Metals One converts its loan notes it will own 30% of Lions Bay.
Distil's distribution nightmare
Now, onto the week's big fallers. Distil (AIM:DIS) was the week's ugliest story, with the RedLeg Spiced Rum and Blavod Black Vodka owner shedding around 40% after warning that full-year revenues would miss expectations by a material margin and that it faces an immediate funding crunch.
The culprit was a classic distribution squeeze: stock piling up unsold in the trade network globally, which strangled incoming orders even as consumer demand for its brands actually grew, while successive duty hikes and a delayed US launch of Blavod piled on further pain.
Premier African Minerals Ltd (AIM:PREM, OTC:PRMMF) had another rough week, with shares off 37% and down more than 95% over the past year, leaving the company with a market cap of just £2 million, after it raised a modest £750,000 by issuing 5.95 billion new shares at 0.0126p each to keep the lights on at its Zulu lithium and tantalum project in Zimbabwe.
The cash will go toward commissioning the Xinhai flotation plant and covering operating costs, but the sheer volume of shares issued at that price tells its own story about where the company currently finds itself.
Mission impossible for marketing group
And finally, MISSION Group (LSE:TMG) was off 28% over the week after the marketing and communications specialist swung to a pre-tax loss of £18.8 million for 2025, from a £2.9 million profit a year earlier, with a £15.7 million impairment charge doing most of the damage alongside a 44% drop in headline operating profit as clients tightened budgets and took longer to make decisions.
There were some crumbs of comfort in falling debt levels and £4 million of annualised cost savings from its restructuring programme, with the company saying early 2026 trading is at least tracking in line with expectations.
