Enphase Energy Inc. guided for better-than-expected sales in the current quarter, boosting the stock of the microinverter maker by more than 6% in the extended session Tuesday.

Enphase said it expects sales between $340 million and $380 million in the first quarter, which compares with FactSet expectations of $338 million in sales.

Wall Street was keeping a close and cautious eye on Enphase’s outlook ahead of Tuesday’s numbers, due to “elevated competition in U.S. and continued softness in EU,” Truist analysts said earlier this week.

The solar-power company earned an adjusted 94 cents a share on revenue of $382.7 million in the fourth quarter. That was ahead of the FactSet consensus for adjusted EPS of 73 cents on sales of $377 million.

The jump in revenue between quarters was due to higher microinverter sales, Enphase said, but it added that its revenue in Europe fell by about 25% in the fourth quarter.

“The decline in revenue was the result of a further softening in European demand,” Enphase said.

Shares of Enphase have lost 35% in the past 12 months, contrasting with gains of around 22% for the S&P 500 index.
