| The Company anticipates a significant change in results of operations for the year ended December 31,
2024, as compared to the year ended December 31, 2023. Net income increased from Ps.4.3 billion in 2023 to Ps.10.5 billion in 2024, representing
an increase of more than 145%. This increase change was primarily driven by a favorable movement in the foreign exchange result, which
improved from a loss of Ps.2.4 billion in 2023 to a gain of Ps.5.6 billion in 2024, as well as a decrease in cost of sales from Ps.52.2
billion in 2023 to Ps.50.6 billion in 2024. Please refer to the Company's report on Form 6-K filed with the SEC on April 30, 2025 for
more information on its financial condition and results of operation in 2024 |
