Shares were flat in early trade at -0.5% below Wednesday's close, with results largely in line with analysts' estimates after the carmaker lowered its outlook in mid-July to 6.5-7% from 7-7.5%.
The German carmaker is also in the midst of a 10 billion euro ($10.83 billion) savings drive announced last December, with cuts of up to 4 billion euros due in 2024.
Volkswagen's core brand operating return sank to 5% under the weight of restructuring costs, while Audi's returns were hit by supply chain bottlenecks.
The Porsche brand, which has struggled in the first half of the year with supply chain problems and low China sales, also reported lower returns because of high costs related to model launches, Volkswagen said.
Volkswagen's second-quarter earnings before interest and taxes came in at 5.46 billion euros, from 5.6 billion euros in the previous year.
The company's results were also dented by costs related to a possible closure of an Audi plant in Brussels, lower sales in China and expenses linked to deconsolidating VW Bank Russia.
"A return of 6.3% after six months is too low," Chief Financial Officer Arno Antlitz said in a statement. "We will have to make significant cost-cutting efforts in the second half of the year and beyond in order to achieve our goals."
Volkswagen is revamping its line-up globally with bespoke EV models in particular for the Chinese and U.S. markets, in an attempt to defend market share in China, maintain its share in Europe and grow in the United States.
The carmaker is one of several legacy firms who have called for patience as they improve their product offerings to stay relevant, even as European and U.S. regulators attempt to keep new and cheaper Chinese EVs out of their markets with tariffs.
