Nordstjernan’s conversion of shares in NCC completed

To enable that the shares in NCC AB’s subsidiary Bonava AB (publ) are
distributed to the shareholders in NCC in accordance with the so-called Lex ASEA
-rules, NCC’s principal owner Nordstjernan Aktiebolag has previously requested
that 9,000,000 shares of series A in NCC, held by Nordstjernan, are converted to
shares of series B. The conversion has been completed, meaning that NCC,
following the conversion, has 14,522,665 shares of series A and 93,913,157
shares of series B. NCC has no shares held in treasury.

Following the conversion, Nordstjernan holds 10,700,000 shares of series A and
11,029,774 shares of series B in NCC, which means that Nordstjernan’s share of
the votes in NCC has decreased from approximately 62,2 per cent to approximately
49.4 per cent. Nordstjernan’s share of the share capital remains unchanged and
amounts to approximately 20.0 per cent.

Completion of the conversion of shares was one of the conditions for Nasdaq
Stockholm’s Listing Committee’s resolution to admit Bonava’s shares of series A
and shares of series B to trading on Nasdaq Stockholm. The first day of trading
in Bonava’s shares of series A and shares of series B is expected to be June 9,
2016.
