On 7 August 2025, the Securities and Exchange Commission (“SEC”) issued Memorandum Circular No. 10, Series of 2025, requiring publicly listed companies with Class “A” and Class “B” common shares to amend their Articles of Incorporation and/or By-Laws within one (1) year from the Circular’s effectivity to reflect the declassification of such shares.

In compliance therewith, the Board of Directors of Concrete Aggregates Corp. (“CAC”), on 12 March 2026, approved the amendment of the Seventh Article of the Articles of Incorporation to declassify its 50 million shares previously classified as Class “A” and Class “B” into 50 million common shares.

The amendment was approved and ratified by stockholders representing at least two-thirds (2/3) of the outstanding capital stock at the Annual Stockholders’ Meeting held on 30 April 2026.

The SEC has since approved the foregoing amendment on 24 August 2026, as reflected in the SEC-issued Certificate of Amendment, which CAC received on 26 August 2026.

Date of Approval by Board of Directors Mar 12, 2026
Date of Approval by Stockholders Apr 30, 2026
Date of Approval by Securities and Exchange Commission Aug 24, 2026
