April 30 (Reuters) - Telecommunications services firm

Lumen Technologies ( LUMN ) missed Wall Street estimates for

first-quarter revenue on Tuesday, as customers move away from

its core local wireline telephone services to wireless carriers.

The Monroe, Louisiana-based firm has been facing continued

demand weakness coupled with massive debt, while a decline in

traditional internet services has hurt its top-line growth.

It had earlier said the macro environment and the overhang

of its creditor discussions would pressure results over the next

few quarters.

Lumen has a network of fiber optic and copper cables and

provides cloud-based communication services and IT solutions to

businesses and users, helping them manage calls, messages and

video meetings via a single interface.

The company posted net revenue of $3.29 billion in the first

quarter, compared with analysts' average estimate of $3.37

billion according to LSEG data, a 12% fall from a year earlier.

On an adjusted basis, it posted a loss of 4 cents per share

in the first quarter, compared with earnings of $0.10 per share

a year ago.

Revenue from Lumen's nurture segment - which includes

ethernet - was down 15%, to $777 million in the quarter. It

posted revenues of $582 million from its harvest segment that

includes voice products, down 17.6% over last year.

Lumen has said it continues to expect headwinds in these

categories.

The firm plans to reduce its workforce by less than 7% and

that would be completed by the second quarter, it said earlier

this month.

In January, the company said it had signed a deal with a

group of lenders that would push out its debt maturities to at

least 2029 and provide it with access to more than $2 billion in

fresh capital.

Lumen completed the sale of its EMEA business to

London-based Colt Technology for $1.8 billion in November, as

part of a digital transformation process necessary to hold out

against bigger rivals in the long run.
