(Alliance News) - The following stocks are the leading risers and fallers on AIM in London on Monday.
----------
AIM - WINNERS
----------
ASOS, up 5.4% at 4,717.00 pence, 12-month range 975.2p-5,548p. The online fashion retailer said it has acquired four brands from beleaguered Arcadia Group, including UK high street staples Topshop and Topman. ASOS will pay GBP265 million for the four brands - including Miss Selfridge and HIIT as well - and also buy GBP30 million in stock upfront. HIIT was a sub-brand of menswear retailer Burton, which ASOS has chosen not to acquire. The online retailer is only buying the stock and the brands, so the physical stores still will close. The AIM-listed firm said the acquisitions represent a "compelling strategic opportunity" to become "the number one destination for fashion loving 20-somethings worldwide". ASOS said they are strong brands that would resonate with its key customer base, with brand equity strongest in the UK and an established presence in both the US and Germany, two of the company's key markets.
----------
Mosman Oil & Gas, up 17% at 0.199p, 12-month range 0.01p-0.26p. The firm reported an uptick in the production rate at the Stanley project in the US. The average gross production rate for the Stanley project, which is in east Texas, was 210 barrels of oil per day in the past week, up from the daily average of 139 barrels for the six months to the end of December. Stanley-3 and Stanley-4 continue to produce oil without artificial lift, the oil and gas explorer said. Stanley-3 is averaging a rate of around 50 barrels of oil per day and Stanley-4 about 120 barrels. The second-hand pump-jack installed at Stanley-2 is now fully operational, after some "initial problems" with the motor that required replacing. In the last week the well has averaged over 40 barrels of oil per day.
----------
PetroNeft Resources, up 13% at 1.30p, 12-month range 0.45p-1.32p. The Irish oil and gas exploration company said it has signed a sales and purchase agreement with Belgrave Naftogas to acquire an additional 40% interest in Licence 67 in the Tomsk Oblast region of Russia for USD2.9 million. PetroNeft owns a 50% stake in Licence 67, which it acquired in a state auction in 2009. Back in January, it signed a heads of terms agreement with Belgrave Naftogas, formerly Arawak Energy Russia, which is part of the oil and gas focused Naftogaz Group in Ukraine. PetroNeft has increased its focus on the licence, which contains the two oil fields Ledovoye and Cheremshanskoye, over the last 12 months due to the "significant potential" that it offers in terms of exploration and production, it said.

AIM - LOSERS
----------
Bidstack, down 31% at 7.46p, 12-month range 2.75p-14.19p. The video game advertising firm said it beat market expectations for revenue in 2020 though its loss is set to widen. Bidstack said it anticipates revenue of GBP1.7 million versus GBP140,000 in 2019. However, the firm's pretax loss is expected to widen to GBP7.2 million from GBP5.4 million. The firm said its strategy to focus on the world's largest video games developers and publishers is "progressing well".
----------
Remote Monitored Systems, down 14% at 2.10p, 12-month range 0.11p-6.85p. The survey and inspection services provider said the commissioning of its mask manufacturing machine has been delayed due to two of its engineers testing positive for Covid-19. The London-based company stated two of the engineers from the mask manufacturer Lemu Group tested positive for the virus and are now self-isolating for ten days. Three members of the Pharm 2 Farm team have been recorded as close contacts of the Lemu engineers and will need to self-isolate for ten days. Remote Monitored noted that while other staff members have tested negative, without the Lemu engineers to assist in the completion of the commissioning of the machine - which was scheduled to occur over the weekend - this will now be delayed until after their ten-day quarantine period ends and they are fit to work.
