Jumbo Interactive (ASX:JIN) expects to report fiscal first-half underlying group earnings before interest, tax, depreciation, and amortization (EBITDA) of AU$37.5 million, up from AU$30.6 million last year, and a total transaction value (TTV) of AU$524.7 million, up from AU$453.4 million a year ago, according to a Wednesday Australian bourse filing.

The company said that despite a soft jackpot environment in the period, the lottery retailing division delivered a "resilient" performance with TTV broadly flat on last year, supported by continued momentum in charity and proprietary products.

Following the acquisitions of Dream Giveaway and Dream Car Giveaways, Jumbo expects a provisional AU$2.2 million incremental non-cash amortization expense from acquired intangible assets to be reflected in its statutory fiscal first-half results.

The company's shares fell 3% in recent Wednesday trade.
