Manchester-based online fashion retailer boohoo.com said its revenue rose 51% to £294.6 million and profit before tax soared 97% to £30.9 million in the year to February 28, 2017 — a period that saw it acquire PrettyLittleThing and the Nasty Gal brand.

Mahmud Kamani and Carol Kane, boohoo.com’s joint CEOs, said trading in the first few weeks of the 2018 financial year had also been promising.

“We expect group revenue growth approaching 50% over 2017, which includes growth from the recent acquisitions,  and a group EBITDA margin of approximately 10%.”

In a joint statement, the CEOs said: “It has been a momentous year for us, with strong results and the acquisitions of PrettyLittleThing on 3 January 2017 and the Nasty Gal brand on 28 February 2017.

“Both brands have huge potential and the acquisitions represent a step change in the size, structure and operation of the group.

“We are confident that our expertise combined with the strength and following of our new complementary brands will greatly enhance the group’s future growth and profitability.

“The boohoo brand has achieved outstanding revenue growth and increased profitability margins during the year.

“We continued to grow strongly in the UK, our largest market, whilst international growth exceeded our expectations, particularly in the USA …

“PrettyLittleThing showed strong revenue growth in two months’ of profitable trading since acquisition.

“This year has also seen some major capital and infrastructure expenditure.

“We invested in a large warehouse extension and additional office space to provide for our planned further growth and we have secured planning permission for the next stage of the warehouse expansion.

“We have also invested in a new website platform for boohoo, which has brought many improvements, including website flexibility and response times.”
