“We are happy that we have delivered our adjusted guidance (and) we are confident that we have laid the right foundation going forward,” Deutsche Post CEO Frank Appel told CNBC’s “Squawk Box Europe.”

“Yes, the economic environment is a little more uncertain, but we still believe that we will see solid growth this year globally, and also a continuation of that next year.”

The firm is trying to push through a proposal in Germany to raise stamp prices, with it’s main argument being that the country’s letter post is still cheap compared to other European countries.

A report in January said the German communications watchdog, the Federal Network Agency, had approved the company’s proposed letter price hike.

Speaking on the progress in getting towards a decision, Appel said: “We expect that we will get a more defined decision in the second quarter… and then we can implement some stamp price increase this year.”
