(Alliance News) - The following is a round-up of earnings and trading updates by London-listed companies, issued on Tuesday and not separately reported by Alliance News:

-------

TPXimpact Holdings PLC - London-based IT consulting firm - Says revenue in financial third quarter ended December 31 falls by 3.9% to GBP19.0 million from GBP19.8 million a year before. Gross profit drops by 15% to GBP5.2 million from GBP6.1 million. Looking ahead, TPXimpact now expects revenue in the year ending March 31 to be about GBP80 million. Adjusted earnings before interest, tax, depreciation and amortisation margin is expected to be in a range of 2% to 3%. In financial year 2022, TPXimpact reported revenue of GBP78.7 million. "We have faced some challenges in recruiting the right mix of resource and skill sets on a timely basis to support our new business wins, and this has led to pressure on margins. Combined with client-driven challenges in some parts of the business, these factors have led to a reduction in our revenue and margin expectations for the remainder of the financial year," Chief Executive Bjorn Conway explains.

RBG Holdings PLC - London-based professional services - Terminates employment contract of Chief Executive Officer Nicola Foulston with immediate effect. Says it has lost confidence in Foulston due to "cultural concerns and the execution of the group's strategy". Names Chief Operating Officer Jon Divers as acting CEO. For 2022, RBG expects to deliver revenue and adjusted operating profit to be in line with market consensus.

Kromek Group PLC - Sedgefield, England-based detection technology supplier - Posts revenue of GBP6.8 million for the six months that ended October 31, up 44% from GBP4.9 million the year before. Pretax loss, however, widens to GBP5.7 million from GBP3.1 million, as administrative expenses rise to GBP7.6 million from GBP6.1 million the year before. Adjusted loss before interest, tax, depreciation and amortisation amounts to GBP2.8 million, widened from a loss of GBP600,000 the year before, primarily reflecting "FX impact and inflation related costs," Kromek explains. Looking ahead, says it is on track for record revenue for financial 2023, expecting to report over 45% year-on-year growth. Also expects to be Ebitda positive for the second half of financial 2023.

Instem PLC - Staffordshire, England-based life science software - Expects to report organic and inorganic revenue for 2022 in the region of GBP59 million, up 28% from GBP46 million a year ago. Adds that higher-margin software-as-a-service revenue and significant contract wins have resulted in full-year profit materially in line with market expectations. Market consensus for adjusted pretax profit stands at GBP7.9 million.

Autins Group PLC - Rugby, England-based supplier of acoustic and thermal management technology for the automotive industry - For financial 2022 ended on September 30, revenue decreased by 20% to GBP18.9 million from GBP23.4 million the year before. "The revenue reduction reflected ongoing supply chain issues in the automotive industry primarily related to global semiconductor shortages," Autins says. Pretax loss widens to GBP3.6 million from GBP1.2 million, as gross profit declines by 33% to GBP4.2 million from GBP6.3 million the year before. Declares no dividend for financial 2022. Looking ahead, warns of "difficult" trading conditions, but says it has made a small Ebitda profit of GBP100,000 so far in financial 2023.
