América Móvil Consolidated Results
Throughout the first quarter dollar interest rates remained volatile, hovering between 3.40% and 4.00%, as sentiment in the U.S. alternated between relief that inflation seemingly had come under control; anguish from the potential inflationary consequences of what appeared to be an increasingly hot labor market; and fear of contagion stemming from the fall of important banks in the U.S. and Europe. The value of our operating currencies vis-à-vis the U.S. dollar reflected this volatility, although they all ended up appreciating vs. the dollar in the period (the Argentinean peso being the only exception): the Mexican peso, 7.5%; the Brazilian real, 4.1%; the Colombian peso, 4.7%; and the euro, 1.2%.
Revenue was up 1.7% in the quarter to 208.9 billion pesos, with service revenue declining 2.2% in Mexican peso terms on account of the appreciation of the Mexican peso vs. substantially all our other operating currencies, which reduced the peso value of our international revenue. Correcting for foreign exchange effects, service revenue was up 6.3%, a slightly faster pace than in the prior quarter.
On the fixed-line platform service revenue growth came in at 1.8% at constant exchange rates, its best performance in over a year on the back of a strong expansion of broadband revenue, 9.6%. On the mobile platform revenue grew 9.3%. Mobile service revenue accounted for 62% of total service revenue.
The improvement of fixed-line service revenue growth was driven mostly by Mexico, Brazil and Colombia, jumping to 4.1% from -1.3% the prior quarter in Mexico; to -1.4% from -3.5% in Brazil; and to 4.2% from -3.6% in Colombia. The latter reflect a marked acceleration of fixed-broadband revenue, to -1.3% from -12.9% in the fourth quarter. Corporate networks revenue increased 12.1% in the first quarter, up from 10.5% in the precedent period.
With respect to mobile service revenue, the deceleration reflects the slowdown observed in Colombia and Austria, with the pace of growth being reduced to 2.2% from 4.7% the preceding quarter in Colombia; and to 3.0% from 4.9% in Austria.
EBITDA totaled 82.7 billion pesos in the quarter; it was up 3.2% in Mexican peso terms and 12.6% at constant exchange rates. These figures include the profits obtained from the sale of telecommunication towers in the Dominican Republic and Peru. Adjusting for these profits, EBITDA decreased -2.5% in Mexican peso terms but rose 5.8% at constant exchange rates.
We turned an operating profit of 44.1 billion pesos in the quarter, up 9.7% year-on-year, which helped bring about a 30.1 billion pesos net profit in the quarter, slightly down -2.1% from the year-earlier quarter. The decline in net income had mostly to do with a reduction in foreign exchange gains, down from 22.5 billion pesos in the first quarter of 2022 to 13.7 billion pesos in the first quarter of this year.
Capital expenditures totaled 29.2 billion pesos in the quarter, with share buybacks amounting to 1.9 billion pesos. These items were funded by our operating cash flow, net borrowings of 2.4 billion pesos and the freeing-up of 5.9 billion pesos in assets formerly invested in our pension funds. Our operating cash flow was supported by the sale of towers in the Dominican Republic and Peru that provided 6.4 billion pesos. Dividend income of 0.7 billion pesos also contributed to the funding of our capital outlays.
Our net debt excluding leases totaled 365.1 billion pesos at the end of March, having come down by 16.4 billion pesos from the end-of-December figure. It was equivalent to 1.39 times LTM EBITDAaL.
