NEW YORK ( TheStreet) -- The super PAC supporting Mitt Romney received nearly half of its February donations from an owner of a homebuilding company.

Restore Our Future reported $6.4 million in total receipts for February and Bob Perry, owner of Perry Homes in Houston, donated $3 million.

The super PAC increased its election cycle total to $43.2 million thanks to a couple of half-million dollar donors and a slew of other six-figure givers.

Among the biggest individual donors for the month were a neurosurgeon, a roof manufacturer and a titanium man.

David Humphreys, CEO of roof manufacturing company Tamko Building Products, gave $500,000. Jerry Perenchio of Chartwell Partners, a principal investment firm, also donated $500,000.

There were ten donors who gave $100,000 to Restore Our Future in February: Henry Kravis, co-CEO of publicly traded private-equity firm Kohlberg Kravis Roberts ( KKR - Get Report); Thomas O'Malley, chairman of petroleum refiner PBF Energy; Harold Simmons, chairman of holding company Valhi ( VHI - Get Report), which has a controlling interest in the leading manufacturer of titanium-based products; Philip Geier of consulting firm Geier Group; Rod Aycox of Select Management Resource gave; Dick Boyce of TPG Capital, a private-equity firm; and Kenneth Griffin of Citadel, which manages a large hedge fund.

Additional $100,000 donors included Griff Harsh, a neurosurgeon at Stanford University; William Templeton, who reported he was self-employed in "investments;" and Raymond Ruddy, who is a retiree from Massachusetts.

Simmons has donated $200,000 total to Restore Our Future as he previously donated $100,000. But he is best known for the $1 million he gave to the super PAC supporting Newt Gingrich and the cool $10 million he donated to Karl Rove's super PAC, American Crossroads.

The latest report shows an immense amount of support from deep-pocketed donors as more than 75% of February's funds came from 13 donors who gave $100,000 or more.
