Wirecard reported a 43% gain in third-quarter core profits on Wednesday, as the German payments company awaits the verdict of an independent investigation by KPMG into allegations it has inflated reported sales and profits.

The company confirmed its 2019 guidance and forecast core earnings before interest, taxation, depreciation and amortization (EBITDA) in 2020 of 1-1.12 billion euros ($1.11-$1.24 billion), implying growth of 34% at the mid-point.

Wirecard called in KPMG in response to a series of investigative reports in the Financial Times, the most of recent of which alleged that its finance team had inflated financials at its units in Dubai and Ireland.

CEO Markus Braun has, however, pre-empted the probe's findings in recent media interviews in which he has dismissed the FT's allegations as false while reiterating his bullish view on Wirecard's prospects.

"We can completely reject these allegations," Braun told CNBC Wednesday about the FT articles. "Additionally now, to give the market additional comfort, we do with KPMG another review of what we have already found out," he told CNBC's Julianna Tatelbaum, noting an internal probe that had already be carried out.
