By 1914, San Miguel began to export, with its products finding ready markets in Hong Kong, Shanghai and Guam. When the First World War broke out, exports came to a temporary halt due to difficulties such as shortage of raw materials and the consequent rise in manufacturing costs. It was not until Prohibition was repealed in the United States that San Miguel was able to resume exports to Guam and later to Honolulu, Territory of Hawaii. By the end of 1914, Enrique Brías, after seeing that his efforts and industry had resulted in a progressive and prosperous business, retired from active business life in favour of his son, Antonio Brías y Róxas. In 1918, Antonio Róxas resigned from his position as president.
