More developments this morning in the drama of Broadcom's (AVGO) hostile bid for Qualcomm (QCOM), as Broadcom CEO Hock Tan took to the airwaves to make his case in advance of a meeting between the two sides this Wednesday. Tan appeared around 9:30, Eastern, on CNBC’s Squawk Box with David Faber and Jim Cramer. Tan’s insistent line on the show was “we have a compelling offer,” while he declined to disclose what if anything he might do to sweeten the offer beyond a revised bid he put out a week ago, and which he today reiterated is his “best and final offer." In his open remarks, Tan said “we have gone to shareholders, lot of Qualcomm’s most significant shareholders, and it’s overwhelming, in fact, that they want to see their board engage with us." "Any responsible board would make it a priority to engage with us,” he added, saying he is "very encouraged by our proposed meeting this Wednesday." Faber noted in his own conversations with Qualcomm investors, there is a "continued concern on anti-trust” regulatory matters.
