STOCKHOLM, April 18 (Reuters) - Nordic telecom operators, with their wide range of business exposures, have tended in recent quarters to offer a very mixed earnings picture.

First-quarter results, which kick off next week, promise to be no different -- but this time the picture is even more complicated due to merger speculation following France Telecom's (FTE.PA) declaration of interest in TeliaSonera (TLSN.ST).

TeliaSonera wraps up a busy week on Friday that starts with emerging markets specialist Millicom (MICC.O) on Tuesday, April 22, followed by Swedish operator Tele2 (TEL2b.ST) on Wednesday. Norway's Telenor does not report until the end of the month.

The market expects broadly similar earnings before interest, tax, depreciation and amortisation (EBITDA) excluding items for TeliaSonera to last year's 7.58 billion Swedish crowns ($1.28 billion) and a gain from the fourth quarter.

Analysts said the initial focus will be on Swedish fixed-line and mobile operations, which dominate its business.

They do not expect the company to address the merger question directly in their results statement, but analysts will have a chance to question TeliaSonera executives about their thoughts during a meeting afterwards.

France Telecom's confirmation this week that it was interested and had held exploratory talks has given TeliaSonera shares a 16 percent boost, making up a good chunk of the ground lost since a dismal fourth-quarter report.

"The fourth-quarter numbers were exceptionally bad. We are expecting an improvement on very, very poor numbers," said Lena Osterberg, analyst at SEB Enskilda. But she noted there was huge uncertainty in the market about TeliaSonera's numbers as the company has twice reorganised its business in recent quarters.

Osterberg said that in Euro-Asian operations, the market would be looking to see how far average revenue per user levels (ARPUs) were falling, especially in Kazakhstan, and whether there would be more of a decline in the Baltics as their economies started to be hit. Anders Berg, analyst at Evli, said TeliaSonera still gets a handsome share of earnings from associate companies such as MegaFon and Turkcell.

"The trend of developments there is still expected to remain positive and that of course is important for the view of the company," he said.

As far as the key Swedish business was concerned, Berg said: "There has been a 7 to 8 percent decline in traditional fixed and we expect that to continue. But at the same time, they have shown extremely good progress in the broadband space."
