The letter said the bid "ascribes no value" to NXP or to Qualcomms plans to roll out new devices for the fifth generation of wireless networks known as 5G.The Qualcomm board "has unanimously determined that your amended offer materially undervalues Qualcomm and falls well short of the firm regulatory commitment the board would demand given the significant downside risk of a failed transaction," Jacobs said in his letter."What is the true highest price at which you would be prepared to acquire Qualcomm? Is it per share or is it higher?" Jacobs said.Qualcomm rejected a record 1 billion hostile bid from computer chip rival Broadcom but offered to meet with the Singapore-based firm to discuss the recently increased offer.

In a letter to Qualcomm board members this week, Tan called the offer "extremely compelling compared to any other alternative available to Qualcomm" and called on the board to open talks on the proposal. "Your proposal is inferior relative to our prospects as an independent company and is significantly below both trading and transaction multiples in our sector," the Qualcomm chairman wrote. But he said the deal would be off the table if it fails to win shareholder approval."The move comes three days after Broadcom boosted its offer to a share to create a global giant in the chip-making sector, a deal worth some 6 billion including assumed debt. Jacobs said the offer "raises more questions than it answers" and also fails to address the planned takeover by Qualcomm – the dominant producer of chips for mobile devices – of Dutch manufacturer NXP.

In December, Qualcomm CEO Steve Mollenkopf argued there was "no real path to value" with Broadcom.Broadcom, which has begun a process to reincorporate in the United States, called its sweetened bid its "best and final offer. "However, the board is committed to exploring all options for maximising shareholder value, and so we would be prepared to meet with you to allow you to explain how you would attempt to bridge these gaps.Broadcom made its first offer on November 6th following a visit by its CEO water jet loom to the White House, where he met President Donald Trump and announced plans to move the tech company back to the United States from Singapore.."

The rich offer puts pressure on Qualcomm, which is set to hold its annual shareholders meeting next month.The California-based group said in a letter to Broadcom that the latest offer unveiled earlier this week "materially undervalues Qualcomm" and does not take into account the possibility of a failure to win regulatory approval. The letter from Qualcomm chairman Paul Jacobs to Broadcom chief executive Hock Tan, however, opened the door to talks to discuss "the significant issues that remain unaddressed" in the hostile proposal. If completed, the deal would be the largest-ever in the tech sector and create a powerful player in the booming sector fueled by growth in smartphones and an array of connected devices from cars to wearables. Any merger deal would need to pass muster with regulators in the United States and other markets
