Deutsche Bank shares drop 8% after lender snaps 15-quarter profit streak

Deutsche Bank on Wednesday snapped a 15-quarter profit streak with a narrower-than-expected loss, as it made a provision for an ongoing lawsuit over its Postbank division and confirmed it would not make a second share buyback this year.

Shares provisionally ended the session down more than 8%, despite analysts characterizing the results as broadly solid.

Net loss attributable to shareholders was 143 million euros ($155.1 million), against an LSEG poll of analysts which had predicted a loss of 145 million euros.

Germany's biggest bank had previously flagged it would take a hit in the quarter on the back of the Postbank provision, which it confirmed Wednesday would amount to 1.3 billion euros. The long-running lawsuit by investors alleges Deutsche Bank underpaid to take over the retail banking giant in 2010.

The bank said it remained on track with its distribution commitment to shareholders, which it has previously stated is for a sum in excess of 8 billion euros in share buybacks across the 2021-2025 financial year period.

"On the share repurchase side...unfortunately, prudently we had to step back from the idea of a second repurchase this year, what our focus is now is building excess capital through the back of the year," Chief Financial Officer James von Moltke told CNBC's Caroline Roth in a Wednesday interview.

The lender reported net revenue was up 2% to 7.6 billion euros in the second quarter, while efficiency savings reached 1.5 billion euros.

Revenue reports varied across the business. At its investment bank division, a recent area of strength, they jumped 10% year-on-year to 2.6 billion euros — but fell 3% to 2.1 billion euros in fixed income and currencies. Revenue in corporate banking was nearly flat at 1.9 billion
