Excerpts from Q4 2013 Verizon Earnings Conference Call

January 21, 2014

Michael Stefanski – Verizon Communications Inc. – Senior Vice President, Investor Relations

For the fourth quarter we reported earnings of $1.76 per share on a GAAP basis. This includes several significant non-operational items that I would like to highlight. The largest item is a pretax gain of $6 billion related to the year-end mark-to-market adjustment of pension and OPEB liabilities.

This favorable accounting adjustment is primarily non-cash and is caused by an increase in the discount rate, changes in actuarial assumptions, and a greater-than-projected return on plan assets. On an after-tax basis this gain amounted to $3.7 billion or $1.29 per share.

Partially offsetting this favorable item were pretax charges of $865 million related to the transaction to acquire Vodafone’s 45% stake in Verizon Wireless. These transaction costs include net incremental interest expense of $616 million related to the debt raise in connection with the acquisition and a bridge financing and other costs of $249 million. On an after-tax basis these transaction charges totaled $540 million or $0.19 per share.

Fran Shammo – Verizon Communications Inc. – Executive Vice President and Chief Financial Officer

2013 was a great year for Verizon from both a strategic and financial perspective. Of course, the big strategic milestone was in our agreement to purchase Vodafone’s 45% stake in Verizon Wireless, which will give us sole ownership of the best asset in the global wireless industry.

We have all the necessary financing in place. The special shareholder meetings for both companies are scheduled for one week from today on January 28 and a closing is planned for February 21. As we have stated, the transaction will be accretive to earnings per share by about 10% on day one. Full ownership will also provide access to all the cash flows and give us greater flexibility to develop converged solutions – without any integration and due diligence risks.

Our strategy is to build upon the foundation and strength of our network assets as the platforms for the future growth and innovation. To that end, we are extremely well positioned in the center of the trends that are driving growth in our industry: mobility, broadband, video, cloud services, and security. Sole ownership of Verizon Wireless, along with our portfolio of other assets, will enable us to better leverage our capabilities across the entire business.


[…]

The strength of our financial position enabled us to raise a record-setting amount of capital in the debt markets last September. We ended the year with total debt of $93.6 million, with all the permanent financing in place related to the pending Vodafone transaction.

[…] As far as the Edge program, […] I’m not going to give guidance, John, on where our upgrade rate will be in 2014. As I said, I will give more guidance here once we close the Vodafone transaction. We have a shareholder vote here in a week, so I think it would put us in a very peculiar situation to give further guidance at this point in time.

Michael Rollins – Citigroup – Analyst

[C]an you talk about the total amount of cost cutting that the Verizon Wireless business achieved during 2013 that contributed to the margin expansion you flagged in [the past of the] different initiatives that you were working on.

I was also wondering if you could share your aspirations in terms of the cost-cutting potential for 2014. Thanks.

Fran Shammo – Verizon Communications Inc. – Executive Vice President and Chief Financial Officer

[…] As far as the cost-cutting side goes, look, coming into 2013 we said that Verizon Wireless had already cut about $5 billion worth of cost out of their infrastructure. We said that we are targeting them for another $2 billion in 2013. They actually exceeded that benchmark in 2013.

And, again, I am going to hold on 2014 here and I will give you more guidance when we get to the end of the first quarter. And, again, it is all around our shareholder vote and the acquisition of the Vodafone transaction.

David Barden – BofA Merrill Lynch – Analyst

[I]f I could just follow up on something you guys talked about on the Verizon Vodafone transaction. I think, Fran, you had some estimates about what you thought the flowback was going to be and how it was going to impact trading in your stock. And, obviously, I’m sure there has been a lot of hedging of things that have moved around. If you could maybe give us a little bit of an update on what you think the movement around the stock is going to be around the transaction based on your latest data it would be super helpful. Thanks.

Fran Shammo – Verizon Communications Inc. – Executive Vice President and Chief Financial Officer

[…] On the second question of flowback, look, I think it is getting harder and harder for me to zero in on what the flowback is given what the market has done and the short positions and everybody positioning where they are. As we said when we came into this transaction, we thought the net flowback would be around 300 million shares, but keep in mind we will have somewhere between 4.1 billion and 4.2 billion shares outstanding.

So it is a pretty insignificant, minimal amount based on the volume of daily trading that we think we will have. That is really all the thought I can give you on the flowback at this point in time.

Kevin Smithen – Macquarie Research Equities – Analyst

[I]f Wireline is a third of revenue today where would you like to see that in three years?

Fran Shammo – Verizon Communications Inc. – Executive Vice President and Chief Financial Officer

[…] As far as a three-year view, I guess I will talk maybe a little bit more of that when we get to the end of the first quarter call, but again I’m not going to give any more further guidance. Look, I think we are very satisfied with the asset portfolio we have. With the acquisition of Verizon Wireless and owning 100% of that asset, you are going to see us do more things around converged solutions, so the Wireline assets, in my view, will actually become more valuable over the longer term here with our footprint.


Kevin Smithen – Macquarie Research Equities – Analyst

You mentioned the loss of some of the tax credits for bonus depreciation, etc. When you think about your capital budget for the year are you going to continue to spend at the clip you spent last year for Wireless, given some of the spectrum and strong subscriber growth, or are there risks to the CapEx number to fund some of the higher cash taxes that are likely?

Fran Shammo – Verizon Communications Inc. – Executive Vice President and Chief Financial Officer

[…] From a cash tax standpoint, as I said before, obviously our cash taxes will go up with the acquisition of the 44% of Wireless. I have guided for next year when we announced the acquisition that we would be somewhere in 35% to 36% ETR, so I think at this point that is where we will keep it and I will give you more color once we come out of the first quarter.
