Verizon Communications Inc. is planning to sell investment-grade corporate bonds on Monday, in part to help finance the redemption of close to $1 billion of notes due next year.

The telecommunications firm is marketing 10-year notes, with initial discussions of a yield around 1.2 to 1.25 percentage point more than Treasuries, according to a person familiar with the matter. Citigroup Inc., Mizuho Financial Group Inc., Santander and Wells Fargo Securities are leading the deal, said the person, who asked not to be identified as the details are private.

The proceeds will be used partly to help finance Verizon’s plan to redeem its 2.625% notes due 2026, which the company disclosed on Monday. There are about $985 million of the notes outstanding.

Verizon’s deal is one of more than a dozen deals in the high-grade market on Monday, as borrowers kick off a week that’s expected to see around $30 billion of investment-grade bond sales.
