Updates shares, adds details on investment in paragraph 5, analyst comment in paragraph 8

Jan 5 (Reuters) - QXO QXO.N on Monday said Apollo Global Management APO.N and other investors agreed to commit $1.2 billion in the billionaire Brad Jacobs-led firm to support acquisitions amid a rising dealmaking in the building-products sector.

Shares of the company were up 7% in early trade.

QXO must use the financing to fund one or more acquisitions by July 15, the companies said.

The company tried buying peer GMS for $5 billion in a hostile bid last year, which was ultimately sold to Home Depot HD.N. It, however, closed its $11 billion deal for Beacon Roofing Supply in April.

"This commitment will be extended up to an additional 12 months if a definitive acquisition agreement is executed before the initial commitment period expires," the companies said.

QXO's funding involves a new series of convertible perpetual preferred stock, with an initial conversion price of $23.25 per share, about 18% above its Friday close.

CEO Jacobs is often touted as an M&A guru, having built multibillion-dollar firms in logistics, waste management and equipment rentals.

"We note the Apollo partnership is building off Brad's long-standing relationships and earlier collaborations at United Rentals URI.N," said RBC Capital Markets analyst Mike Dahl.

Dealmaking activity in the U.S. building-products industry has accelerated as companies seek scale and local supply chains to offset tariffs, with demand supported by new housing, repair and renovation, and non-residential construction.

Last year, Commercial Metals CMC.N said it would acquire concrete supplier Foley Products for $1.84 billion, while roofing-material firm TopBuild BLD.N bought rival SPI for $1 billion in cash.

Jacobs stepped down as chairman at XPO XPO.N and GXO Logistics GXO.N in December.
