BREAKING NEWS

First Chinese Geomembrane Company to Far Exceed HDPE Geomembrane Durability Properties (INNO MATERIAL – Innovation leads the future)

Fibromat Ends Maiden Day on ACE Market 10% below IPO Price
Fibromat (M) Bhd (KL: FIBRO) fell 10% on its maiden day on the ACE Market following the geotechnical services firm’s listing transfer from the LEAP Market. 
Shares of Fibromat opened at 46 sen on Thursday, versus its initial public offering price (IPO) of 55 sen per share. The stock slipped to as low as 41 sen and ended the day at 49.5 sen after more than 29 million shares changed hands.
At the closing bell, the company had a market capitalisation of RM123 million.
Fibromat is the latest in a string of first-day flops on the ACE Market as investors turn increasingly selective in poor general market conditions. Before Fibromat, Bursa Malaysia hosted eight ACE Market listings since March, and all sank below their IPO prices on their first day.
Proceeds from the ACE Market IPO will go towards funding purchase of new machinery — including stitching machines and dust collectors — as well as support the formation of an in-house prefabricated vertical drain installation team and the acquisition of five hydraulic excavators.

Court Finds Veolia Provided Outdated Data to an Expert Witness Regarding the Performance of its Landfill Gas Extraction System, which was Deemed Serious Trial Misconduct
Victorian Supreme Court found Veolia Environmental Services in breach of its landfill operating licence and the general environmental duty (GED) under the Environment Protection Act 2017 (Vic). The court determined that Veolia failed to implement all practicable measures to prevent excessive landfill gas emissions from its Hallam Road site between July 2022 and October 2023.

• Veolia submitted landfill gas extraction data to their expert witness that did not reflect the current operational conditions during the period of alleged environmental breaches (July 2022 – October 2023).
• This outdated data misrepresented the effectiveness of the gas control measures in place at the time of the emissions issue.
• The court viewed this as a failure to comply with the obligation of candour and fairness to the court in environmental litigation.
