On January 9th, 2026, the National Institute of Statistics and Geography published in the Federal Official Gazette an update of the Mexican Unit of Measurement and Update (“UMA”)1:
- Daily Value: MXN$117.31 (approximately US$6.52).
- Monthly Value: MXN$3,566.22 (approximately US $198.12).
- Annual Value: MXN$42,794.64 (approximately US $2,377.48).
2 Allamounts expressed in U.S. dollars were calculated using the following exchangerate: MXN$18.00 = US$1.00.
The values reflect a 3.7% increase over the prior year and will take effect on February 1, 2026.
This update modifies the merger control thresholds provided in Article 86 of the Federal Economic Competition Law as follows:
- Section I: When the originating act or sequence of acts, notwithstanding the place of performance, are worth within Mexican territory, directly or indirectly, an amount in excess to the equivalent of MXN 1,876,960,000.00 (approximately USD 104,275,55.56);
- Section II: When the originating act or sequence of acts, imply the accumulation of thirty percent or more of the assets or stock of an Economic Agent, whose annual sales originating in Mexican territory or assets in the country, are worth an amount in excess of the equivalent of MXN 1,876,960,000.00 (approximately USD 104,275,55.56) or
- Section III: When the originating act or sequence of acts, imply an accumulation within Mexican territory of assets or capital stock in excess of the equivalent to MXN 868,094,000.00 (approximately USD 48,227,444.44), and two or more of the Economic Agents participating in the concentration have annual sales originating in Mexican territory or assets in Mexican territory which are worth, jointly or separately, an amount in excess of MXN 4,692,400,000.00 (approximately USD 260,688,888.89).
Likewise, it is important to consider that the fines that can be imposed by the National Antitrust Commission are fixed in UMAs, so these will also be increased in 3.7%.
