STOCKHOLM--Investor AB said Friday that its second-quarter total shareholder return was 9%, unchanged on the year, as economic activity rebounded from "the gloomiest days" experienced at the beginning of the quarter.

Investor's net asset value per share rose to 564 Swedish kronor ($62.07) at the end of June from SEK494 at the end of March. On an adjusted basis, NAV rose to SEK641 a share.

Net profit attributable to shareholders for the second quarter was SEK64.37 billion, up from SEK18.07 billion a year earlier.

"While Covid-19 has had a severe impact on people and the global economy, it has also given us insights to build upon," Chief Executive Johan Forssell said.

"Furthermore, the pandemic has accelerated the already strong trends of digitalization, automation and integration of sustainability into business operations," he added.

Investor said that in recent years its companies worked to secure agility and have entered this crisis in good shape.

Companies will have to evaluate and potentially adjust business models, supply chains, customer offerings and ways of working, it said.

Investor is the investment vehicle of Sweden's prominent Wallenberg family and owns stakes in some of the country's largest companies, including telecom giant Ericsson, home-appliance manufacturer Electrolux AB and lender Skandinaviska Enskilda Banken AB.
