Oxford Biomedica PLC (LON:OXB) has been boosted by vaccine news.

The company, a key manufacturer of the Oxford/AstraZeneca PLC (LON:AZN) COVID-19 vaccine, has doubled its expectations for revenue from the contract.

The gene and cell therapy group said AstraZeneca had increased the number of batches required for the jab in the second half.

It now estimates its revenues from the vaccine will be £100mln, up from previous forecasts of £50mln.

The company’s shares have jumped 128p or 12.77% to 1130p, making it the biggest riser in the FTSE 350.

3.15pm: Repairs group sees profits damaged

Homeserve PLC (LON:HSV) has seen its profits take a hit after writing off a customer relationship managment system.

The home services and repair business, which also owns Checkatrade, saw full year profits slump by 66% to £47.2mln, partly due to an £84.8mln write-down.

Chief executive Richard Harpin said: “One of the most difficult decisions we took this year was to halt the implementation of eServe, the UK CRM solution we procured in 2013… eServe was highly configured to our business and became costly and inflexible to implement, with further configuration issues emerging as implementation progressed. It will be replaced by a more flexible, cloud-based solution.”

It was upbeat about the outlook, saying: “With homeowners set to continue to spend on their homes and compelling plans in place to continue to build attractive customer, partner and trades propositions, the group is well positioned for further strong growth.”

But its shares have dropped 7.47% or 77.5p to 959.5p.

2.32pm: Tile specialist hopeful of second half recovery

It was a tale of two quarters for Topps Tiles PLC (LO:TPT).

In its first quarter – the three months to December – it benefited from its shops reopening as lockdown was lifted.

But as we all know, restrictions were soon imposed again and the three months to March this year bear the scars.

So overall revenues for the first six months of the tile and wood flooring specialist fell 2.8%, but adjusted profits rose from £1.2mln to £5.1mln.

And now we are back in the reopening phase, the company has seen a rapid increase in sales, giving it confidence for the second half.

Chief executive Rob Parker said: “Inevitably, our first half results reflect two sharply contrasting periods of trading.  An exceptionally strong performance in the first quarter demonstrated the ability of the business to bounce back following the initial lockdown.  Our performance in the second half, while materially stronger than in the first lockdown, was heavily impacted by the re-imposition of COVID-19-related trading restrictions at the start of the period.

“The re-opening of our stores to all customers on 12 April has once again been received very positively and we have seen a strong recovery in sales and gross margins, with retail like-for-like sales 16.8% ahead of the same period in 2019 in the five weeks since re-opening.  We are confident of a much-improved performance in the second half and believe the group remains well positioned to take advantage of an expected increase in consumer spending.”

Topps shares have added 5.55% to 74.2p.

12.10pm: Direct marketing group upbeat on prospects

4imprint Group Plc (LON:FOUR) is in demand after it gave a positive update to shareholders at its annual meeting.

Since its results in March, momentum in the business has grown, with order intake in April above 80% of 2019 levels. In the most recent three weeks, order counts have averaged 85% against the same 2019 comparative.

The news has sent its shares 5.65% higher to 2430p.

10.46am: Network group links up with US utilities specialist

CyanConnode Holdings PLC (LON:CYAN) has signalled a new partnership and seen its shares jump sharply.

The company, a specialist in narrowband radio frequency mesh networks that facilitate machine to machine communication, has signed an alliance with California’s SEW (Smart Energy Water). SEW is an energy and water cloud platform provider serving more than 300 utilities worldwide.

Under the terms of the agreement, the two companies will promote and sell each others products, as well as refer potential customers to each other, expanding the geographical reaches of each company.

CyanConnode chairman John Cronin said: “This partnership with SEW… will maximise sales potential in existing as well as new territories while widening the company’s global distribution channels.”

SEW founder and chief executive Deepak Garg said: “The energy and utilities industry worldwide is going through a major transformation in customer experience and mobile workforce operations. SEW is delighted to partner with CyanConnode and offer its customers CyanConnode’s intelligent communication solutions, in the knowledge that this technology has been proven by worldwide commercial scale deployments.”

Elsewhere Oxford Technology 4 Venture Capital Trust PLC (LON:OXF) has surged by 50% to 24p.

The move comes after one of its investee companies, Arecor Therapeutics PLC, said this week  it would join AIM in a £20mln IPO next month.

Oxford said: “Assuming the placing and admission takes place at a share price in the range indicated, the company’s value of its investment in Arecor is anticipated to increase. The Board intends to make a further announcement that will quantify that impact, after the admission has taken place.”

9.46am: Mining group gains after expansion news

Tertiary Minerals PLC (LON:TYM) has made another step to expanding its copper interests.

It is forming a subsidiary in Zambia – Luangwa Minerals Limited – to target exploration and development opportunities for the metal in the country..

It has retained geologist Marcel Nally, formerly a director of private Zambian copper producer Moxico Resources, and expects to appoint him exploration manager in due course. It  has also retained Shangwa Chime as Luangwa’s government liaison officer.

Tertiary will hold 96% of Luangwa, with 3% being held by Mr. Nally and 1% held by Mr. Chime.

Executive chairman Patrick Cheetham said: “Given that the Board has many years of experience with Zambian mining projects, we are excited to take this next step in the development of Tertiary’s mineral business. Copper is increasingly a focus for the company and with Zambia one of the world’s top 10 copper producing countries, producing nearly 900,000 tonnes of copper in 2020, we expect Luangwa to be a valuable addition to the Tertiary asset portfolio.”

The company’s shares have jumped 16.92% or 0.06p to 0.38p.

8.55am: Oil company boosted by regulatory approval

Egdon Resources PLC (LON:EDR) has seen its shares bubble higher after a positive update from its Wressle oil field in North Lincolnshire.

It has received the necessary consents to start a proppant squeeze operation – a hydraulic fracturing process – to optimise oil production from the Ashover Grit reservoir, one of three productive reservoirs it has been testing.

Its Wressle-1 well has been on 24 hour test production since late January with the oil produced then being  transported by road tanker to the Phillips 66 Humber refinery and sold under Egdon’s existing oil sales contract. 

The company said production rates had exceeded its expectations, with high quality free flowing oil being produced and no water present. The well will continue operating on test production until the proppant squeeze operation is started.

Egdon managing director Mark Abbott said: “We are delighted to have received all the required regulatory consents for the proppant squeeze operation at Wressle. When successfully completed, this will realise the full potential from the Ashover Grit reservoir and is expected to increase Egdon’s net production to 150 barrels of oil per day at a time of increasingly strong oil prices leading to a step change in our cash flow.”

Egdon is 18.75% or 0.3p higher at 1.9p while Union Jack Oil PLC (LON:UJO), which has a 40% economic interest in the Lincolnshire licences has added 8.14% or 2.85p to 37.85p.

Union Jack executive chairman David Bramhill said: “The proppant squeeze operation is the final phase of achieving our targeted oil production level and generating optimum cash flows from the Ashover Grit reservoir.”
