(Alliance News) - The following is a round-up of updates by London-listed companies, issued on Tuesday and not separately reported by Alliance News:
----------
Helix Exploration PLC - London-based helium exploration and development company - Raises GBP2.2 million through the placing of 8.8 million shares at 25 pence each. Hannam & Partners acted as sole bookrunner and broker in connection with the placing which was conducted by way of an accelerated book build process. Proceeds will be used principally for: operational working capital; Inez re-entry & perforation; and corporate general and administrative expenses.

Deltic Energy PLC - investor with an exploration and appraisal portfolio in the southern and central North Sea - Viaro Energy Ltd buys an additional 300,000 shares in Deltic at a price of 3.75p per share. This takes Viaro's holding to 2.4 million shares, 2.6% of Deltic's share capital. Francesco Mazzagatti, chief executive says: "This reflects our confidence in the quality of the Deltic assets and the long term value they can deliver, and aligns with our disciplined approach to capital allocation and value creation." Last June, Deltic agreed a bid from Viaro bidco, Rockrose Energy Ltd, worth 7.46 pence per Deltic share, valuing the company at around GBP6.9 million on a fully diluted basis. The deal has been delayed due to regulatory concerns, and remains subject to outstanding conditions including the consent of the North Sea Transition Authority. In December, Deltic said the UK North Sea regulator requires further representations from Rockrose and Deltic "in order to reach a definitive conclusion in relation to concerns it has which will affect whether it will grant the proposed change of control of the licences held by Deltic".

"The consortium is currently considering its position. There can be no certainty that an offer will be made nor as to the terms of any offer," the consortium says.

Tinicum is a Tiburon, California-based investor, which "manages a diversified group of manufacturing, distribution, industrial technology and specialty infrastructure companies", according to its website.

Chief Executive Simon Peckham says: "We thank our shareholders and lending partners for their ongoing support as Rosebank builds on the momentum of its first acquisition, ECI, with the addition of two more businesses, MW Components and CPM, with strong potential for improvement. Alongside ECI, MW Components and CPM significantly strengthen our ability to drive sustained profit improvement and deliver attractive shareholder returns as we continue to execute our proven "Buy, Improve, Sell" strategy."

Additionally, since November 2024 GM has provided the company with operational support and financial assistance including advance payments of GBP14.4 million. Surface Transforms says it has not yet had the opportunity to speak directly with GM about the termination, but warns the loss of this contract has a "material" impact on its ability to trade.
