Verizon Communications Inc. rewarded investors with a profit of about $2.09 billion for agreeing to buy the record $49 billion of bonds it sold yesterday as the price of the securities surged.

The company’s $15 billion of 30-year debentures, the biggest portion of the eight-part deal, traded at 105.714 cents on the dollar yesterday, up from an issue price of 99.883 cents, according to Trace, the bond-price reporting system of the Financial Industry Regulatory Authority. They extended the gains today to 106.737 cents as of 9:04 a.m. in New York. The $11 billion of 10-year notes rose 3.461 cents to 103.137 cents yesterday, continuing the climb today to 103.815.

Demand soared after the New York-based phone company offered yields that were higher than market rates to raise interest in an offering that was about the size of all the outstanding obligations of the Slovak Republic amid the worst selloff in the bond market since 2008. The 10-year securities were priced to yield 225 basis points more than similar maturity Treasuries, or 47 basis points wider than bonds with similar maturities and ratings, according to data compiled by Bloomberg.

“Two billion seems like a big number to leave on the table,” Peter Tchir, the founder of hedge-fund adviser TF Market Advisors, said in a telephone interview. “Maybe Verizon was just so happy to get the deal done. That’s a pretty big price move for any size issue.”

‘Big Number’

Bob Varettoni, a Verizon spokesman, declined to comment on the sale and the secondary trading levels. The sale is almost triple the previous record of $17 billion that Apple Inc. issued in April, Bloomberg data show.

Verizon’s sale was managed by Barclays Plc, Bank of America Corp., JPMorgan Chase & Co. and Morgan Stanley, the company said in regulatory filings. The underwriters were paid $265.3 million in fees, according to a regulatory filing.

The five biggest holders of Verizon debt based on regulatory filings are Vanguard Group Inc., BlackRock Inc., Prudential Financial Inc., MetLife Inc. and Capital Research & Management Co., Bloomberg data show. The company’s existing bonds lost 3.95 percent in the week leading up to the offering.

Proceeds from the offering, along with $14 billion of loans, will help finance Verizon’s buyout of partner Vodafone Group Plc.’s 45 percent stake in the largest and most profitable U.S. wireless carrier, Verizon Wireless.
