April 19 (Reuters) - French voucher and benefits company Pluxee raised its full-year organic sales growth target on Friday, after delivering a strong half-year performance in the group's first earnings report since its Euronext Paris debut in February.

Citing a favourable macro environment, Pluxee is now targeting between a 15% and 17% increase in its organic revenue growth for the year, compared to the low double-digit percentage increase it forecast in January.

"This is the result of a very good sales performance. Over the last two years, we've seen very good momentum, but it's a momentum that's continuing, both in terms of signing new customers ... development and annual volumes," CEO Aurelien Sonnet told Reuters in an interview.

Earnings before interest, taxes, depreciation, and amortisation (EBITDA) came in at 201 million euros ($214 million) for the period between September and February, representing 28% organic growth compared with the previous year.

It was "a performance across the board, in all the regions in which we operate," Sonnet said.

Employers have been turning to voucher companies like Pluxee to support staff without having to increase wages, and to offer perks to encourage workers to return to the office rather than work from home.

The group maintained its mid-term guidance of low double-digit percentage organic sales growth until 2026.

Competitor Edenred on Thursday reported first-quarter operating revenue that beat estimates with a growth of 18.8% to 625 million euros.
