Prima Marine Shares Jump as Major Shareholder Launches Voluntary Offer at Premium

The share price of Prima Marine rose as much as 8.8% to THB 8.65 per share on Friday, following the report of its major shareholder’s intention to increase position in the company at a premium price.

Nathalin Company Limited, the majority shareholder of Prima Marine Public Company Limited (SET: PRM), has officially announced its intention to launch a voluntary general offer to acquire additional shares. This strategic move is driven by the Offeror’s belief in the company’s long-term business growth potential and a view that the acquisition represents a “worthwhile investment”.

Currently holding 61.07% of PRM’s total issued and paid-up ordinary shares, Nathalin seeks to purchase up to 155,555,500 additional shares, representing a 7.01% stake. The offer price is set at 9.00 Baht per share. Shareholders who choose to participate will be responsible for a 0.25% brokerage fee, plus a 7.00% value-added tax (VAT) on that fee.

From a regulatory standpoint, this transaction does not constitute a mandatory tender offer. Because Nathalin’s total holding will remain below 75% upon completion, the deal is not subject to the requirements of Section 247 of the SEC Act or standard business takeover procedures.

The offer period is scheduled for 12 business days, running from 27 April 2026 to 14 May 2026. In a move to protect investor interests, the transfer of securities will only take place after 7 May 2026. This ensures that shareholders who accept the offer remain entitled to receive dividends as of the Record Date. Kasikorn Securities has been appointed as the official Offer Agent for the deal.
