Saudi Aramco said it’s still working on a deal to buy a $15 billion stake in Reliance Industries Ltd.’s refining and chemicals business, even as lower oil prices force it to slash other investments.

Reliance’s shares fell in mid-July after Chairman Mukesh Ambani said a transaction had been delayed “due to unforeseen circumstances in the energy market and the Covid-19 situation.”

A deal with India’s Reliance would help the world’s biggest crude exporter join the ranks of the top oil refiners and chemical makers. State-owned Aramco, which bought chemical firm Saudi Basic Industries Corp. for $70 billion this year, is already a major supplier of crude to India, while Reliance sells petroleum products such as gasoline to the kingdom.

“We are still in discussion with Reliance,” Aramco Chief Executive Officer Amin Nasser said on a call with reporters on Sunday. “The work is still on. We will update our shareholders in due course.”

A deal could be finalized around the first quarter of next year, according to Deven Choksey, managing director at KR Choksey Investment Managers Pvt. in Mumbai. Aramco will win twice over, he said.

“It will get an assured consumer for its hydrocarbon resources, while becoming a 20% partner in a ready-made business of developing a value-added chain in specialty chemicals,” Choksey said.

Reliance’s stock fell 1.3% in Mumbai on Monday, paring its gain this year to 41%. Aramco rose 0.2% to 33.10 riyals in Riyadh.

Aramco reported on Sunday that second-quarter net income was down almost 75% from a year earlier. The coronavirus pandemic halted travel and business, slashing demand for crude and fuel. After the Organization of Petroleum Exporting Countries cut production, Brent prices rebounded from a low of about $16 a barrel in April to nearly $45, though they’re still down 32% this year.

Aramco’s downstream unit narrowed its loss in the second quarter. The loss before interest and taxes for the business was $344 million, compared with $866 million a year earlier.

Ambani, the world’s fourth-richest person, said last year that Aramco was set to buy a 20% stake in his company’s refining and petrochemicals business, valuing it at $75 billion.

The Reliance transaction would help Aramco reach its goal of more than doubling refining capacity to between 8 million and 10 million barrels a day. The Saudi firm had capacity of 3.6 million barrels a day at the end of last year, including wholly owned plants and stakes in joint ventures. The gross capacity of facilities in which Aramco has stakes was 6.4 million barrels daily.

The company, officially known as Saudi Arabian Oil Co., is working to start the 400,000 barrel-a-day Jazan refinery on Saudi Arabia’s southern Red Sea coast this year. It also owns the biggest refinery in the U.S. as well as plants in countries such as South Korea and Japan. It’s planning several Chinese ventures.

Reliance’s need for a cash infusion has eased in recent months. The conglomerate raised some $30 billion by attracting investments from the likes of Google and Facebook Inc. into its digital unit, Jio Platforms Ltd., and by selling shares to existing stakeholders.
