The investment firm seeking to buy and take private BlueLinx announced today it has extended by another week its offer to buy the 45% of outstanding shares it doesn't already own.

Cerberus ABP Investor LLC (CAI), an affiliate of Cerberus Capital Management L.P., said in a news release that it did so "to permit CAI and Cerberus a further opportunity to discuss and negotiate the terms of the offer with the special committee of the board of directors of BlueLinx formed to consider the offer." That three-member panel was organized on July 22, the day after CAI gave notice of its tender offer, but as of yet it hasn't announced its opinion.

CAI's offer to pay $3.40 per share to buy roughly 14.6 million BlueLinx shares--an offer worth about $49 million--was to expire at midnight Aug. 27, but on Aug. 13 it extended that deadline to Sept. 3. CAI then presumably upped the pressure on BlueLinx to act when it gave notice on Aug. 20 that it would kill its offer unless the special committee that shareholders in the Atlanta-based distributor accept the investment group's terms.

Today's announcement pushes the new deadline for the offer to midnight ET Friday, Sept. 10. As of 5 p.m. today, Aug. 26, just over 383,000 shared had been tended and not withdrawn, CAI said.

BlueLinx provides products from more than 750 suppliers to 11,500 customers nationwide. It reported on Aug. 5 a net loss of $3.4 million for the second quarter, swinging from a year-earlier profit of $600,000. That loss occurred despite a 27.7% increase in revenues to $540.8 million.
