CEO Comments

“We are pleased with the solid performance of our business as AFFO per share grew by nearly 9% in the first quarter,” said John P. Case, Realty Income’s Chief Executive Officer. “During the quarter, we completed $371 million in high-quality acquisitions at attractive investment spreads to our cost of capital. Our portfolio continues to be healthy as occupancy remained at 98.3% while we recaptured approximately 104% of expiring rent on properties re-leased to existing or new tenants.”

“We remain committed to maintaining a high-quality balance sheet as we raised approximately $1.5 billion in well-priced permanent and long-term capital during the quarter. Common equity now represents approximately three-quarters of our capital base. We continue to have outstanding financial flexibility to grow our business with ample liquidity on our $2.0 billion line of credit and the lowest cost of capital in the net lease industry.”

Financial Results

Revenue

Revenue for the quarter ended March 31, 2017 increased 11.6% to $298.0 million, as compared to $267.1 million for the same quarter in 2016.

Net Income Available to Common Stockholders

Net income available to common stockholders for the quarter ended March 31, 2017 was $71.6 million, as compared to $63.5 million for the same quarter in 2016. Net income per share for the quarter ended March 31, 2017 was $0.27, as compared to $0.25 for the same quarter in 2016.

Net income and funds from operations available to common stockholders for the quarter ended March 31, 2017 were impacted by a $13.4 million non-cash redemption charge on the Class F preferred shares that were redeemed in April 2017, which represents $0.05 per share. This charge is based on the excess of redemption value over the carrying value of the Class F preferred stock that represents the original issuance cost that was paid in 2012.

Net income and funds from operations available to common stockholders for the quarter ended March 31, 2017 were impacted by a non-cash gain of $1.3 million, or $0.005 per share, resulting from fair value adjustments on our interest rate swaps. Each quarter we adjust the carrying value of our interest rate swaps to fair value. The changes in the fair value of our interest rate swaps are recorded to interest expense.

The calculation to determine net income for a real estate company includes impairments, gains on property sales and/or fair value adjustments on interest rate swaps. These items can vary from quarter to quarter and can significantly impact net income and period to period comparisons.

Funds From Operations Available to Common Stockholders (FFO)

FFO for the quarter ended March 31, 2017 increased 9.7% to $187.2 million, as compared to $170.6 million for the same quarter in 2016. FFO per share for the quarter ended March 31, 2017 increased 4.4% to $0.71, as compared to $0.68 for the same quarter in 2016.

Adjusted Funds From Operations Available to Common Stockholders (AFFO)

AFFO for the quarter ended March 31, 2017 increased 14.4% to $201.3 million, as compared to $175.9 million for the same quarter in 2016. AFFO per share for the quarter ended March 31, 2017 increased 8.6% to $0.76, as compared to $0.70 for the same quarter in 2016.

The company considers FFO and AFFO to be appropriate supplemental measures of a Real Estate Investment Trust’s (REIT’s) operating performance. Realty Income defines FFO, a non-GAAP measure, consistent with the National Association of Real Estate Investment Trusts’ (NAREIT’s) definition, as net income available to common stockholders, plus depreciation and amortization of real estate assets, plus impairments of real estate assets, and reduced by gains on property sales. AFFO further adjusts FFO for unique revenue and expense items, which the company believes are not as pertinent to the measurement of the company’s ongoing operating performance. Presentation of the information regarding FFO and AFFO is intended to assist the reader in comparing the operating performance of different REITs, although it should be noted that not all REITs calculate FFO and AFFO in the same way, so comparisons with other REITs may not be meaningful. FFO and AFFO should not be considered as alternatives to reviewing our cash flows from operating, investing, and financing activities. In addition, FFO and AFFO should not be considered as measures of liquidity, our ability to make cash distributions, or our ability to pay interest payments. See the reconciliations of net income available to common stockholders to FFO and AFFO on pages six and seven of this press release.
