The company was due to release results on 10 March and hold its shareholders' meeting towards the end of April.
It has not said by how much these events will be delayed.
It says results will be about the same as in 2014, although the cost of the crisis will eat into those.
It said it was working on "valuation calculations".
Sales in VW-branded cars dipped last year after the scandal - which affected 11 million cars - came to light in September. Deliveries fell 5.3% in October, 2.4% in November and 7.9% in December compared with those months in 2014.
It was its first drop in VW-branded sales in 11 years as the company continues to cope with the emissions scandal.
VW has promised it will have a fix in the coming weeks for the millions of US cars with defeat devices that disguised emission levels in diesel cars.
Sales of VW-brand cars fell 4.8% in 2015 to 5.82 million cars from 6.12 million a year earlier.
The US Environmental Protection Agency is suing the company over what it says were 600,000 affected vehicles and a US law firm is conducting an investigation into who made the decisions to cheat.
Volkswagen says it is sticking to its plan to publish the findings of its investigation into the scandal in the second half of April.
Results from Porsche, which is owned by Volkswagen, are also being delayed.

General Vladimir Padrino tweeted that the "leaders and masterminds of the paramilitary and terrorist assault" had been arrested.
The suspects are a 38-year-old former captain, Juan Carlos Caguaripano Scott, and a lieutenant, Jefferson Garcia.
Two of the rebels were killed and eight seized after the incident in Valencia.
Venezuela has seen four months of violent anti-government protests, and almost 130 people have died in clashes.
Just before the barracks attack, a video released on social media showed the uniformed men saying they were rising against the "murderous tyranny of President NicolÃ¡s Maduro".
"This is not a coup but a civil and military action to re-establish constitutional order," said the leader, who gave his name as Juan Caguaripano.
Venezuelan officials say Mr Caguaripano was discharged from the army in 2014. They claim he commanded around 20 uniformed men during the attack.
He then escaped with Lieutenant Garcia and some stolen weaponry, they say.
The 6 August incident raised tensions in the divided country, where critics of President Maduro say he is trying to cement a dictatorship.
Mr Maduro insists his actions - which include creating a pro-government assembly with the power to rewrite Venezuela's constitution - are the only way to re-establish peace.
The US has led a chorus of international alarm against the Maduro government in recent weeks, and has imposed sanctions on several high-ranking Venezuelans - including the president.
President Donald Trump said on Friday that he had not ruled out "a possible military option if necessary" against Venezuela.
Gen Padrino dismissed the claim as an act of "craziness". He told Venezuela's state television: "It is an act of supreme extremism. There is an extremist elite that rules the United States.
"As a soldier, I stand with the Venezuelan armed forces, and with the people. I am sure that we will all be on the front lines of defending the interests and sovereignty of this beloved Venezuela."
The White House said Mr Maduro had requested a phone call with his US counterpart on Friday. It said President Trump would speak to Venezuela's leader "as soon as democracy is restored in that country".
Volkswagen says it will not release its results nor hold its shareholders' meeting on time, as it needs more time to work out its accounts as a result of last year's emissions crisis.
