To President,

PTT Oil and Retail Business Public Company Limited ("OR") is pleased to submit the Company' s financial statements and consolidated financial statements for the three-month and six-month periods ended June 30, 2022, which have been reviewed by EY Office Limited and approved by OR's audit committee, as well as the Operating Results for the three-month and six-month periods ended June 30, 2022

Performance 2Q/22 PTT Oil and Retail Business Public Company Limited and its subsidiaries ("OR") recorded total sales and services in the amount of THB 211,431 million, an increase of THB 34,140 million from the last quarter, mainly due to the rise in average global oil prices following higher demand induced by recovery of economic activities caused by easing measures to control the spread of COVID-1 9 in many countries, including Thailand. Meanwhile, the supply is still tight due to the sanctions on Russia. All of the mentioned factors resulted in higher sales revenue for all business segments: Mobility business and Global business recorded an increase in the overall oil sales volume by 2 . 0 % and 2.4%, respectively, leading to an increase in revenue. For the Lifestyle business, sales and services revenue increased from the previous quarter due to the higher demand from the economic recovery, the relaxation of COVID-19 measures and the Thai holiday season.

We recorded an EBITDA of THB 10,240 million in 2Q/22, an increase of THB 3,773 million compared to 1Q/22, increasing in all business segments. The EBITDA of our Mobility business grew from an increase in gross profit, mainly due to increased sales volume from the aviation fuel in the commercial market and diesel from the retail market recovered from reduced pressure in the market. The EBITDA of our Lifestyle business improved from the Other Non-Oil business. Global business increased in line with higher gross margins in the Philippines and Cambodia. Aggregate net operating expenses increased, including slightly higher depreciation, in line with our network expansion for both Mobility and Lifestyle business segments. In addition, this quarter, we recorded higher gains on the foreign exchange due to the weaker Thai baht against the U.S. dollar. OR recorded a net profit of THB 6,568 million, an increase of THB 2,723 million, leading to an earnings per share of 0.55 baht.

Performance 1H/22 OR recorded a net profit of THB 10,413 million, an increase of THB 3,185 million from the first half of last year, mainly due to the increase in both total sales and services and EBITDA by THB 151,554 million and THB 4,840 million, respectively, as a result of the economic recovery from COVID-19 where the government applied more easing measures, thus improving the overall performance in all business segments. Sales volume increased in all business segments; however, in 1H/22, net operating expenses increased by 13.2%, mainly from variable expenses, in line with the increase in sales from resumption of economic activities.
