An Atlanta REIT that has been investing heavily in New York's office market could be the target of a takeover.

Columbia Property Trust hired an adviser to court potential buyers, Bloomberg reports. The firm received interest from undisclosed firms looking to buy it earlier this summer, sources told Bloomberg, but the offers were not compelling enough. Bloomberg also reported there was a slim chance an agreement would be reached.

The REIT, which trades on the New York Stock Exchange as CXP, focuses on investing in office buildings in gateway markets. More than 80% of its portfolio is invested in New York, San Francisco and Washington, D.C., according to a recent presentation filed with the Securities and Exchange Commission.

Among the trophy assets in its portfolio include 333 Market St., a 33-story tower in San Francisco's Financial District, the iconic Market Square office building off Pennsylvania Avenue in D.C. and 149 Madison Ave., a 127K SF tower in Midtown South, which it is currently redeveloping.

CXP also has a roster of strong tenants in its portfolio, including AT&T, Twitter, Wells Fargo Bank, DocuSign Inc. and Snap Inc. Most recently, Columbia secured the headquarters for Inspire Brands — the parent company of fast-food chains Arby's and Buffalo Wild Wings — at Three Glenlake, an office complex in suburban Atlanta.
