Johannesburg - Mvelaphanda (Mvela) and Rebserve would embark on capital raising just as soon as the R4 billion deal had been concluded, they said yesterday.
The two firms will be amalgamated into one entity by July.
Mark Willcox, the chief executive of Mvela, said the capital raising would cater for future deals, some of which were already being negotiated.
The companies planned to raise the capital using debt instruments, shares or a combination of the two.
Mvela, which looked at a number of companies before settling on Rebserve, announced on Monday that it would merge and reverse list into Rebserve, creating the country's first black-controlled, owned and managed diversified industrial group.
Willcox said Mvela was looking for a good operating company where its empowerment shareholding would bring benefit to each and every one of Mvela's assets.
"We were also attracted to the management, which has a track record of not only doing deals but turning them into value," said Willcox.
He added that obviously there was a complementary mix of assets.
Rebserve is an investment holding company with interests in facilities management and professional services, food services and support services.
Telecommunications Facilities Management Company (TFMC) may have been one of the Rebserve businesses to catch Mvela's eye immediately.
TFMC manages the outsourced property management and infrastructure operations of telecoms utility Telkom.
Worth R1.5 billion a year, the contract was awarded about three years back and spans 10 years. Telkom was expected to save about R300 million in facilities management costs each year.
Besides telecoms interests, Mvela's assets include interests in mining, financial services, healthcare and property.
The company holds 23 percent of Mvelaphanda Resources, South Africa's second-largest listed black mining group after African Rainbow Minerals.
It more recently added a 15 percent stake in Gold Fields' local operations to its resources portfolio and is the main member of a consortium that has a 10 percent stake in Absa.
Because the transaction is a reverse takeover, Mvela gains 55 percent of the new entity and effectively lists its assets without the formality of a public offering.
While the shares in Rebserve will more than double, its shareholders will get a special dividend of 75c and a capitalisation award of the same amount, giving them a total value of R8.50 a share.
Willcox said there had been a lot of local and international interest in the deal.
On the JSE Securities Exchange, shares in Mvela closed unchanged yesterday at R23.25, although the resources index added 0.47 percent.
Rebserve shares fell 35c to close at R8.65 in line with the diversified industrials sector, which declined 0.04 percent.
