Pre-tax profits fell 37 per cent to £526m, while revenue rose 32 per cent to £6.12bn, though it was down 1.5 per cent when adjusted for the acquisition of EE.
Total adjustments relating to the investigation of its Italian business amounted to £268m for prior year errors and a specific item charge of £245m for changes in accounting estimates (£145m for the second quarter and £100m for the third).
Reported earnings per share were down 59 per cent, while adjusted earnings per share were down 24 per cent.
Why it's interesting
On the bright side, the UK broadband market grew by 189,000 customers and BT's retail share was 83,000 - or 44 per cent. Openreach has halved missed appointments year-on-year. And, well, there's record growth in the telecoms' giant's EE mobile unit.
But as chief executive Gavin Patterson said: "The good progress we're making across most of the business has unfortunately been overshadowed by the results of our investigation into our Italian operations and our outlook."
Quite. Shares have fallen 20 per cent over the past few days, since the company announced revenues would be hit hard by financial impropriety in the Italian business. European chief Corrado Sciolla has left the company, following the discovery of the accounting irregularities too.
What the company said
Gavin Patterson, chief executive, said: "We've undertaken extensive investigations into our Italian business, including an independent review by KPMG, and I am deeply disappointed with the unacceptable practices by some that we've found. This has no place at BT, and it undermines the good work we're doing elsewhere in the group. We are committed to ensuring the highest standards across the whole of BT."
Looking forward, Patterson added the firm faces "a more challenging outlook" in the UK public sector and international corporate markets.
