The Swiss company, bought by state-owned ChemChina for $43 billion in 2017, posted a 2% rise in sales to $12.04 billion for the six months ended June 30, while earnings before interest, tax, depreciation and amortization (EBITDA) increased 7% to $2.22 billion.

Syngenta said it had overcome low grain prices, which reduced the ability of farmers to invest in fertilisers and pesticides, and disruptions caused by the COVID-19 pandemic by controlling costs and maintaining supplies.

Chief Executive Erik Fyrwald said an IPO of Syngenta was still being planned.

"The commitment was within five years of when we closed the deal with ChemChina. That was in June of 2017. So mid-year of 2022 would be the five year mark," Fyrwald told reporters.

"We believe we are on track to achieve that."

ChemChina, which owns 100% of Syngenta, wants to list the Basel company on China's technology-focused STAR market, Reuters reported in December.

Syngenta Group, which was created from a merger of Syngenta, Israel's ADAMA and the agricultural business of Sinochem, is now looking at ways to restructure the debts it took on following the ChemChina takeover.

"We have no specific actionable plan that we want to relate to. But the restructuring of the debt is also at the heart of the IPO," Chief Financial Officer Chen Lichtenstein said.

The company, which competes with Germany's Bayer and BASF, said the rest of the year remained "challenging," although crop prices could rise due to extreme weather events, Fyrwald said.
