Brookfield Infrastructure Reports First Quarter 2018 Results

BROOKFIELD, NEWS, May 02, 2018 (GLOBE NEWSWIRE) -- Brookfield Infrastructure (NYSE: BIP) (TSX:BIP.UN) today announced its results for the first quarter ended March 31, 2018.

					Three Months Ended March 31
US$ millions (except per unit amounts), unaudited						2018		2017
Net income (loss)1					$	209	$	16
– per unit2,3					$	0.42	$	(0.03	)
FFO4					$	333	$	261
– per unit5					$	0.85	$	0.71

Brookfield Infrastructure reported net income for the quarter of $209 million ($0.42 per unit) compared to net income of $16 million (loss of $0.03 per unit) in the prior year. During the quarter, a gain of $209 million (net of tax) was recorded, relating to the sale of our investment in a Chilean electricity transmission business. Results from the period reflect better operating performance generated across the majority of our operations, which was offset by higher depreciation and foreign exchange.

FFO of $333 million increased by 28% compared to the prior year. Results reflect the contribution of new investments, as well as solid organic growth across our various businesses. Our payout ratio⁶ for the period was 68%, which remains within our target range of 60-70%.

“2018 is off to a good start. With the sale of our Chilean electricity transmission business, we continue to demonstrate our full cycle investment strategy,” said Sam Pollock, Chief Executive Officer of Brookfield Infrastructure. “The proceeds dramatically increased our total liquidity, which now stands at over $4 billion. We can use this substantial liquidity to fund our strong backlog of organic growth projects and opportunistically deploy into new investment initiatives on a value basis.”

Segment Performance

Our utilities segment contributed FFO of $169 million compared to $100 million in the prior year. This step-change increase was primarily attributable to the contribution from our Brazilian regulated gas transmission business acquired in April 2017, and to a lesser extent, an increase in our rate base and upward inflation adjustments in our other utility businesses.

Our transport segment reported FFO of $137 million in the period, compared to $123 million in the previous year. This increase was driven by higher tariffs and volumes in our Brazilian rail and South American toll road businesses. Results were partially offset by lower contribution from our ports business, and foreign exchange which reduced our results by $4 million.

Our energy segment generated FFO of $66 million, compared to $62 million in the same period last year.  This improvement captures the incremental contribution from new contracts, higher gas transport volumes and further equity invested into our North American natural gas transmission operations. Results were partially offset by lower contribution from our gas storage business that is being impacted by a weak spread environment. 

Our communications infrastructure segment generated FFO of $19 million for the first three months of 2018, which remained unchanged from the prior year. The business delivered results in-line with expectations due to its stable and predictable cash flow profile.

The following table presents FFO by segment:

					Three Months Ended March 31
US$ millions, unaudited						2018			2017
FFO by segment
Utilities					$	169		$	100
Transport						137			123
Energy						66			62
Communications Infrastructure						19			19
Corporate						(58	)		(43	)
FFO					$	333		$	261

Update on Strategic Initiatives

We have executed on several initiatives that will contribute to our results and liquidity:

(I)  Chilean Electricity Transmission – In March, Brookfield Infrastructure closed on the sale of its 28% interest in Transelec for $1.3 billion ($1.1 billion net of tax), achieving a compound internal rate of return of approximately 18% on a pre-tax basis. Transelec provided us with strong and predictable cash flows, however, we see opportunities to reinvest the net proceeds from the sale at significantly higher returns.  

(II)  Colombian Gas Distribution – The previously announced acquisition of a controlling interest in Gas Natural S.A. ESP, the second largest gas distribution network in Colombia, is advancing well. We initially acquired 11% and are currently progressing the second phase of the acquisition. Upon completion, this would result in Brookfield Infrastructure and its institutional partners owning a controlling interest in the company. In early April, we received anti-trust approval and once approvals have been received from the local securities regulator, we will launch a tender offer.

Distribution

The Board of Directors has declared a quarterly distribution in the amount of $0.47 per unit, payable on June 29, 2018 to unitholders of record as at the close of business on May 31, 2018. This distribution represents an 8% increase compared to the prior year. The regular quarterly dividends on the Cumulative Class A Preferred Limited Partnership Units, Series 1, Series 3, Series 5, Series 7 and Series 9 have also been declared.
