MaxLinear CEO Kishore Seendripu expects the deal to drive earnings and free cash flow higher:

Exar's expertise in power management and interface technologies, along with an extensive distribution platform, should enable us to accelerate our growth, capitalize on cross-selling opportunities and better serve our customers. Our successful M&A track record is a testament to our careful and thoughtful approach to acquisition integration, and we expect the same with Exar. The increased scale and related financial benefits of the transaction should result in immediate non-GAAP EPS accretion and increased free cash flow.

While MaxLinear didn't provide details on the exact effects the deal will have on earnings and free cash flow, the company does expect to achieve $15 million of annualized synergies within 12 months of closing.

Now what

Exar CEO Ryan Benton believes that the combination will benefit both its customers and employees: "MaxLinear's commitment to and its proven track record of providing its customers with innovative and differentiated high performance analog, mixed-signal and RF technology will present exciting new opportunities for our employees, customers and supply chain."

A tender offer will commence within the next 20 business days, with 20% of Exar shares already in support of the deal. The companies anticipate the deal to close during the second quarter of 2017.
