Sports marketing agency TLA Worldwide plc (LON:TLA) sprang 20.6% higher to 2p in lunchtime trading after a resolution to sell its Australian business was approved by shareholders at a general meeting.

The growth was driven by an 11% rise in memberships, which totalled 796,000 at the end of June (H1 18: 720,000), while revenue per member hit £15.47 per month (H1 18: £14.65), reflecting the increasing popularity of the premium LIVE IT membership.

Amigo also ditched its commitments to lowering its net debt and increasing its dividend in the short-term.

Recruiter Hays PLC (LON:HAYS) was also on the slide, falling 2.3% to 135.9p after it posted a 3% drop in pre-tax profits for 2019 while also warning of lower business confidence in Germany and Britain as clients cut back on costs and delayed decision making amid economic uncertainty.

Pre-tax profit fell to £231.2mln in the year to 30 June from a year ago due to higher commission payments, the cost of restructuring operations in Europe and new rules that require companies to equalise pension benefits for men and women.

However, net fees – a key measure of gross profit for recruiters – rose 5% to £1.1bn, led by growth in Germany – its largest market.

9.45am: Horizonte Minerals shares go vertical as it secures US$25mln funding deal for Araguaia project

Shares in nickel miner Horizonte Minerals PLC (LON:HZM) soared 49.6% to 5p in early trading following a US$25mln deal with investment firm Orion Mine Finance to develop its Araguaia project in Brazil.

Orion is one of the market’s largest financiers of mining projects with around US$5.1bn currently under management.

Horizonte said Orion will provide the funds up front in exchange for a 2.25% royalty on the project, which would apply to the first 426,429 tonnes of nickel produced and sold, equivalent to the estimated nickel production over the life of the Araguaia mine according to a feasibility study at the site.

The funds from Orion would enable the company to build out its owner’s team at Araguaia as well as advancing engineering and early works packages before starting full construction of the mine.

In the oilers, Union Jack Oil gushed 11.4% higher to 0.3p after it told investors that partners in the West Newton project now believed it is a “significant oil and gas discovery”.

Meanwhile, in the fallers, FTSE 100 IT firm Micro Focus International PLC (LON:MCRO) tumbled 27.6% to 1,126.8p after it announced plans to accelerate a strategic review of the business and slashed its revenue guidance for the year.

The group said weak sales execution has been compounded by a deteriorating macro environment, which has led customers to delay buying decisions.

“There remains a significant pipeline of business opportunity being pursued but to be within the current guidance range a highly challenging percentage of this pipeline would need to close prior to year-end,” the company said.

It now expects a revenue decline of 6% to 8% for the year to 30 October, down from a previous forecast for a drop of 4% to 6%.
