Tieto Corporation STOCK EXCHANGE RELEASE 5 October 2016, 10.45 am EET

Tieto today published new comparison figures based on its new business
structure. The release published at 9.00 EET included tables with incorrect
segment information. Correct figures are available as an attachment in this
release.

Tieto’s operating model and structure have been aligned to the strategy launched
in March 2016. The new structure, effective as from 1 July, is based on service
lines and industry groups. In line with the new operating model, Tieto has
changed its financial reporting. As from the third-quarter interim report, to be
published on 25 October, reporting will be prepared in accordance with the new
structure.

The service lines are:

  · Technology Services and Modernization
  · Business Consulting and Implementation
  · Industry Solutions
  · Product Development Services.

They constitute reportable segments for Tieto. The company will disclose the
customer sales and operating profit among others of these reportable segments.

Additionally, Tieto will disclose customer sales by industry groups, which are:

  · Financial Services
  · Public, Healthcare and Welfare
  · Industrial and Consumer Services.

Tieto's financial reporting for 2015 and the first half of 2016 has been
adjusted to account for the changes. The figures may still be subject to changes
during the year. Comparison figures are available in the attachment Comparison
