LUXEMBOURG, April 26, 2018 (GLOBE NEWSWIRE) -- Tenaris S.A. (NYSE:TS) (BAE:TS) (BMV:TS) (MILAN:TEN) (“Tenaris”) today announced its results for the quarter ended March 31, 2018 in comparison with its results for the quarter ended March 31, 2017.

Summary of 2018 First Quarter Results

(Comparison with fourth and first quarter of 2017)

	1Q 2018		4Q 2017				1Q 2017
Net sales ($ million)	1,866		1,589		17	%	1,154		62	%
Operating income ($ million)	212		168		26	%	36		489	%
Net income ($ million)	235		162		45	%	206		14	%
Shareholders’ net income ($ million)	235		160		47	%	205		15	%
Earnings per ADS ($)	0.40		0.27		47	%	0.35		15	%
Earnings per share ($)	0.20		0.14		47	%	0.17		15	%
EBITDA ($ million)	354		319		11	%	198		79	%
EBITDA margin (% of net sales)	19.0	%	20.1	%			17.2	%

In the first quarter of 2018, sales, which rose 17% quarter on quarter and 62% year on year, were boosted by an exceptional level of shipments for East Mediterranean pipelines and a high level of sales during the peak Canadian drilling season. Earnings per share, operating income and EBITDA continue to recover and benefit from higher absorption of fixed costs although the EBITDA margin was affected by higher raw material costs and lower margins on the East Mediterranean shipments. 

During the quarter, we had a further increase of working capital of $364 million, reflecting an increase in receivables associated with a high level of sales towards the end of the quarter. Net cash flow used in operations amounted to $30 million. After capital expenditures of $92 million, our net cash position declined to $557 million at the end of the quarter.

Market Background and Outlook

In the year to date, shale drilling activity in the USA has grown steadily while, in Canada, growth is being affected by takeaway capacity constraints and wider commodity price spreads. In the rest of the world, higher oil prices are leading to a gradual recovery in onshore drilling activity. In Latin America, despite promising results from the reform programs in Brazil and Mexico and further interest in the Vaca Muerta shale play in Argentina, drilling activity has been slow to pick up outside Colombia and the new deepwater play in Guyana.

The full extent of US Section 232 tariffs on steel imports is still unclear but as far as imports of steel pipes are reduced by quotas or the application of the 25% tariff, Tenaris expects to be well placed to increase production at its US domestic facilities.

In the coming quarters, we expect shipments to be lower than the first quarter but sales and margins should benefit from price increases that compensate recent increases in raw material costs. EBITDA and operating income should continue to show growth through the year.

Analysis of 2018 First Quarter Results

Tubes Sales volume (thousand metric tons)	1Q 2018	4Q 2017			1Q 2017
Seamless	651	593	10	%	509	28	%
Welded	285	171	67	%	74	283	%
Total	936	764	23	%	583	61	%

Tubes	1Q 2018		4Q 2017				1Q 2017
(Net sales - $ million)
North America	807		707		14	%	477		69	%
South America	285		296		(4	%)	203		40	%
Europe	153		133		15	%	130		17	%
Middle East & Africa	456		290		57	%	230		98	%
Asia Pacific	66		51		29	%	46		45	%
Total net sales ($ million)	1,766		1,478		20	%	1,085		63	%
Operating income ($ million)	194		150		29	%	31		524	%
Operating margin (% of sales)	11.0	%	10.1	%			2.8	%

Net sales of tubular products and services increased 20% sequentially and 63% year on year. In North America sales increased 14% sequentially, reflecting high sales in Canada in the peak drilling season and higher sales in the United States onshore. In South America sales declined 4% sequentially, as slightly higher sales of OCTG in Argentina were offset by lower sales elsewhere. In Europe sales increased 15% thanks to an increase in demand for mechanical pipe and line pipe for power generation and hydrocarbon processing industry. In the Middle East and Africa sales increased 57%, boosted by an exceptional level of shipments of line pipe products for the Zohr project in the East Mediterranean and stable sales elsewhere. In Asia Pacific sales increased 29% thanks to higher shipments throughout the region and particularly in Thailand.

Operating income from tubular products and services amounted to $194 million in the first quarter of 2018, compared to $150 million in the previous quarter and $31 million in the first quarter of 2017. The sequential increase is a result of an improvement in the margin on higher sales. While during the quarter average selling prices declined 2% (reflecting a mix of products with higher participation of welded line pipe products) and costs of sales remained stable (higher direct cost of sales offset by a positive volume effect on fixed costs), the operating margin improved following the reduction of selling, general and administrative expenses as a percentage of sales.

Others	1Q 2018		4Q 2017				1Q 2017
Net sales ($ million)	100		111		(10	%)	68		46	%
Operating income ($ million)	19		18		2	%	5		246	%
Operating income (% of sales)	18.7	%	16.5	%			7.9	%

Net sales of other products and services decreased 10% sequentially but increased 46% year on year. The sequential decrease in sales is mainly related to lower sales of sucker rods.

Selling, general and administrative expenses, or SG&A, amounted to $350 million, or 18.7% of net sales, in the first quarter of 2018, compared to $344 million, 21.6% in the previous quarter and $294 million, 25.5% in the first quarter of 2017. Sequentially, SG&A declined as a percentage of sales due to a better absorption of fixed costs on higher sales and lower provisions for contingencies and doubtful accounts and the termination of the amortization of intangible assets of our Canadian subsidiary for $13 million.

Financial results amounted to a loss of $8 million in the first quarter of 2018, compared to a gain of $4 million in the previous quarter and a loss of $4 million in the first quarter of 2017. The loss of the quarter is mainly explained by lower interest results on a lower net cash position and a foreign exchange loss, net of derivatives results, of $7 million, mainly related to the negative impact from Euro appreciation against the U.S. dollar on Euro denominated intercompany liabilities in subsidiaries with functional currency U.S. dollar. The net foreign exchange loss is to a large extent offset in equity, in the currency translation adjustment reserve.

Equity in earnings of non-consolidated companies generated a gain of $46 million in the first quarter of 2018, compared to a gain of $26 million in the previous quarter and a gain of $35 million in the first quarter of 2017. These results are mainly derived from our equity investment in Ternium  (NYSE:TX) and Usiminas (BSP:USIM).

Income tax charge amounted to $15 million in the first quarter of 2018, positively affected by currency movements on the tax base used to calculate deferred taxes at our subsidiaries which have the U.S. dollar as their functional currency for $20 million. This compares to an income tax charge of $36 million in the previous quarter and an income tax gain of $47 million in the first quarter of last year positively affected by the effect of the Mexican and Argentine peso revaluation on the tax base used to calculate deferred taxes at our Mexican and Argentine subsidiaries which have the U.S. dollar as their functional currency.

Cash Flow and Liquidity

Net cash used in operations during the first quarter of 2018 was $30 million as we had a further increase of working capital of $364 million, reflecting an increase in receivables associated with a high level of sales towards the end of the quarter, compared to a cash generation of $26 million in the first quarter of 2017 and $13 million used in the previous quarter.

Capital expenditures amounted to $92 million for the first quarter of 2018, compared to $121 million in the previous quarter and $139 million in the first quarter of 2017.

At the end of the quarter, our net cash position amounted to $557 million, compared to $680 million at the beginning of the year.

Exhibit I – Alternative performance measures

EBITDA, Earnings before interest, tax, depreciation and amortization.

EBITDA provides an analysis of the operating results excluding depreciation and amortization and impairments, as they are non-cash variables which can vary substantially from company to company depending on accounting policies and the accounting value of the assets. EBITDA is an approximation to pre-tax operating cash flow and reflects cash generation before working capital variation. EBITDA is widely used by investors when evaluating businesses (multiples valuation), as well as by rating agencies and creditors to evaluate the level of debt, comparing EBITDA with net debt.

EBITDA is calculated in the following manner:

EBITDA= Operating results + Depreciation and amortization + Impairment charges/(reversals).

(all amounts in thousands of U.S. dollars)	Three-month period ended March 31,
	2018	2017
Operating income	212,197	36,014
Depreciation and amortization	141,802	162,218
EBITDA	353,999	198,232

Net Cash / (Debt)

This is the net balance of cash and cash equivalents, other current investments and non-current investments less total borrowings. It provides a summary of the financial solvency and liquidity of the company. Net cash / (debt) is widely used by investors and rating agencies and creditors to assess the company’s leverage, financial strength, flexibility and risks.

Net cash/ debt  is calculated in the following manner:

Net cash= Cash and cash equivalents + Other investments (Current)+ Non Current Investments – Borrowings (Current and Non-current).

(all amounts in thousands of U.S. dollars)	At March 31,
	2018		2017
Cash and bank deposits	328,675		427,619
Other current investments	999,576		1,613,665
Non Current Investments	234,739		316,003
Borrowings	(1,005,595	)	(708,231	)
Net cash / (debt)	557,395		1,649,056

Free Cash Flow

Free cash flow is a measure of financial performance, calculated as operating cash flow less capital expenditures. FCF represents the cash that a company is able to generate after spending the money required to maintain or expand its asset base.

Free cash flow is calculated in the following manner:

Free cash flow= Net cash (used in) provided by operating activities – Capital expenditures.

(all amounts in thousands of U.S. dollars)	Three-month period ended March 31,
	2018		2017
Net cash (used in) provided by operating activities	(29,567	)	26,134
Capital expenditures	(91,938	)	(138,615	)
Free cash flow	(121,505	)	(112,481	)
