Subject of the Disclosure
Buy-Back of Semirara Shares
Background/Description of the Disclosure
The Board of Directors of Semirara Mining and Power Corporation (the “Corporation”) at a special meeting held today have approved the Corporation’s buy-back program to enhance shareholder value and to provide stockholders an opportunity to liquidate their investments under the following terms and conditions: 1. Buy-back up to Two Billion Pesos (P2,000,000,000.00) worth of common shares based on trading price at the open market through the trading facilities of the PSE beginning December 8, 2017. 2. The capital structure of the Corporation before the buy-back program is as follows: Authorized Capital Stock - 10,000,000,000 Issued Shares - 4,264,609,290 Outstanding Shares - 4,261,145,720 Treasury Shares - 3,463,570 3. The Corporation cannot accurately determine at this time its capital structure after the buy-back program since the actual number of shares to be repurchased will depend on the total buy-back price of the shares; 4. The buy-back is not an active and widespread solicitation, nor will it involve substantial number of shares, and will not adversely affect the Corporation’s prospective and existing development projects.
