Publicly traded piano icon Steinway Musical Instruments is relying on outside financial communications counsel through its $438M buyout offer by Kohlberg & Co.

pianoNew York-based Lippert Heilshorn & Associates is advising the Waltham, Mass.-based maker of musical instruments. Managing director Jody Burfening and senior VP Harriet Fried are on the account at LHA, which had advised the company prior to Kohlberg deal as well.

Steinway announced the $35-per-share tender offer (33% premium) with the private equity firm on July 1. Steinway will become a privately held company if shareholders approve the deal.

In a statement, Kohlberg partner Christopher Anderson noted Steinway's 160-year history. "We feel fortunate to be selected to partner with Steinway and further its commitment to serving its artists and customers worldwide by producing the finest pianos and musical instruments available," he said.

Steinway, which includes the New York-founded piano maker Steinway & Sons, has 45 days to seek out other proposals under a "go-shop" clause.

The companies hope to close the deal by the third quarter.

Steinway shares were up 15% in morning trading July 1 to top $35. Revenue for 2012 was more than $352.7M.
