BUENOS AIRES, Nov 7 (Reuters) - Argentina's

state-controlled energy company YPF swung to a net

loss of $198 million in the third quarter , the company said on

Friday, crediting the loss to a sharp increase in YPF's income

tax expense, specifically a deferred tax charge.

The company's adjusted earnings before interest, tax,

depreciation and amortization (EBITDA), a key measure of

industry profitability, stood at $1.36 billion for the

July-to-September period, down 1% from a year earlier and in

line with the expectations of analysts polled by LSEG.

Revenues were $4.64 billion, the firm said in a filing,

down 12% from the same quarter last year and a touch below

analysts' $4.76 billion estimate.

The company said its total production reached 523,100

barrels per day, down 6% from a year ago.

Shale oil production, meanwhile, rose 35% year-on-year

to average 170,000 barrels per day. Excluding the effect of

YPF's sale of the 49% stake in Aguada del Chañar, shale

production was up 43%, the company said.
