Oct 26 (Reuters) - THG has appointed an executive from backer SoftBank to its board of directors and is looking for an independent chair ahead of a proposed premium listing on the London Stock Exchange (LSE), the company said on Tuesday.

The British e-commerce group has been working to soothe investor nerves after its shares plunged by 35% in a single session this month following an investor presentation focused on its Ingenuity unit, which THG plans to spin off. Investors had expected more specifics about the business.

Tuesday's announcement accompanied THG's quarterly trading statement, in which it gave an upbeat outlook for the Ingenuity sales and logistics platform, predicting that 2022 revenue from Ingenuity will exceed current market expectations by 20-25%.

Shares in THG, which have fallen 60% this year, were up 1% at 310 pence in early trading on Tuesday.

The company, which went public in a bumper initial public offering last year, owns beauty retailer Lookfantastic and supplements firm Myprotein.

Japanese venture capital giant SoftBank, which bought a just under 10% stake in THG in May, has an option to inject a further $1.6 billion into Ingenuity at a valuation of $6.3 billion once it is spun off.

Since the poorly received presentation, THG founder Matthew Moulding has sought to reassure investors by giving up his "golden share", seeking a premium listing for THG and foregoing a pledge of some of his THG shares as collateral for a loan facility.

A premium LSE listing demands stricter corporate governance standards from companies and could give them greater visibility through the FTSE indices. THG is currently listed on the standard segment of the LSE.

The group said on Tuesday it had appointed SoftBank executive Andreas Hansson, who serves on the boards of a number of the Japanese conglomerate's portfolio companies, as a non-executive director to its board.

It also said it had engaged a consultant to search for a new independent chair, to align itself to UK corporate governance rules before its proposed premium listing.
