Jan 28 (Reuters) - Beacon Roofing Supply ( BECN ) said

on Tuesday it has adopted a limited duration stockholder rights

agreement, commonly known as a poison pill, following a hostile

takeover bid by QXO.

Beacon is issuing one preferred share purchase right for

each outstanding share of its common stock to stockholders, by

way of a dividend, as of Feb. 7, the company said.

The rights agreement was intended to protect the company and

its stockholders from "anyone seeking to opportunistically gain

control of Beacon without paying all stockholders an appropriate

control premium", Beacon said.

"The only thing stopping shareholders from acting to get

cash expeditiously is the decision by Beacon's Board to adopt a

poison pill," QXO Chief Executive Brad Jacobs said.

QXO took its

$11 billion takeover offer

for Beacon Roofing to shareholders on Monday, after the

roofing materials' distributor repeatedly rebuffed its offer.

Beacon urged its shareholders not to take any action and said it

would evaluate QXO's offer.

The tender offer, which has remained unchanged since

QXO's Nov. 11 proposal according to Beacon, would be outstanding

until Feb. 24, QXO said on Tuesday.

QXO, which is looking to enter the massive but

fragmented building products distribution industry, said on

Monday that it plans to complete the acquisition quickly after

the tender offer expires in 20 business days, subject to its

terms.

It also said it had secured full-financing commitments

from Goldman Sachs, Morgan Stanley, Citi, Credit Agricole, Wells

Fargo and Mizuho.
