Revenues exceeded £1bn for the first time.
But year on year sales growth continues to drop with sales in the 4 weeks to Christmas rising 8% year on year, a decline from 10% in 2018 and 15% in 2017.
Much of this growth is likely to have been driven by new store openings, with like for like sales figures not provided by the grocer.
Aldi has seen its operating profit margin fall below 2% as it competes with an increasingly efficient Big 4.
The grocer has been forced to invest in distribution facilities as well as premium ranges and store improvements in order to attract customers.
Analysts have stated that the Christmas results suggest a "1 or 2 percent" like for like sales increase, with profitability down due to increasing price competitiveness and marketing spending ahead of Christmas.
