Our sales in the fourth quarter of 2023 rose 5% sequentially, boosted by a high level of shipments to the Middle East and for offshore pipeline projects, together with the inclusion of our newly acquired Shawcor pipe coating business, which offset the ongoing pricing declines in the Americas. Our EBITDA at $975 million declined mainly due to lower average selling prices in the Americas. Our net income of the quarter, of $1.1 billion was positively affected by: i)$167 million higher result from non-consolidated companies; ii) $26 million higher financial results and iii) net deferred tax gain of $360 million.

Our free cash flow for the quarter amounted to $669 million after capex payments of $167 million. Additionally, during the quarter we paid $161 million (net of cash) for the acquisition of the Shawcor pipe coating business from Mattr. Following dividend payments of $235 million and $214 million spent on share buybacks during the quarter, our net cash position increased to $3.4 billion at December 31, 2023.

Summary of 2023 Annual Results

	12M 2023		12M 2022		Increase/(Decrease)
Net sales ($ million)	14,869		11,763		26	%
Operating income ($ million)	4,316		2,963		46	%

EBITDA ($ million)	4,865		3,648		33	%
EBITDA margin (% of net sales)	32.7	%	31.0	%

*For the calculation of per share and per ADS data we have used average number of shares outstanding excluding treasury shares.

In 2023, our net sales, EBITDA and net income reached record levels. The year was characterized by a first half, in which prices in the Americas reached exceptional levels and we had a high level of pipeline shipments in Argentina, and a second half, in which prices in the Americas started to return to more normal levels while overall sales were supported by good activity and pricing levels in the Middle East and for offshore pipelines.

Operating margins expanded reflecting the higher prices realized on the sales of most of our products, which more than compensated for higher costs of goods sold.

Net income benefited from a net positive deferred tax effect of $194 million as well as positive financial results of $221 million.

Operating cash flow for the year amounted to $4,395 million (including a $182 million reduction in working capital). After capital expenditures of $619 million, business acquisitions of $266 million, dividend payments of $637 million and $214 million spent on share buybacks, our net cash position increased to a record level of $3.4 billion at the end of the year.

Market Background and Outlook

In an environment where oil prices remain relatively stable, oil supply and demand is balanced, and the long term outlook for natural gas, especially LNG, is promising, drilling activity in North America is stabilizing, while continuing to increase in the Middle East and offshore. In this context, and considering our expanded perimeter, with our recent acquisition of the Shawcor pipe coating business, we expect that, in the first half of 2024, our sales will be in line with those of the second half of 2023.

After the exceptional levels they reached in the post-Covid recovery, tubular price levels and margins in the Americas have returned to sustainable levels and should stabilize in the coming months. Prices and margins in the rest of the world should remain at good levels supported by strong demand for offshore operations and pipeline projects.

In Latin America, fundamental conditions remain favorable for the continued expansion of drilling activity and tubular demand, but the high level of political and economic volatility may affect these prospects.

Annual Dividend Proposal; Second Tranche of Share Buyback Program

Upon approval of the Company´s annual accounts in March 2024, the board of directors intends to propose, for approval of the annual general shareholders’ meeting to be held on April 30, 2024, the payment of a dividend per share of $0.60 (in an aggregate amount of approximately $700 million), which would include the interim dividend per share of $0.20 (approximately $235 million) paid in November 2023. If the annual dividend is approved by the shareholders, a dividend of $0.40 per share ($0.80 per ADS), or approximately $465 million, will be paid on May 22, 2024, with an ex-dividend date on May 20, 2024 and record date on May 21, 2024.

The second $300 million tranche of the Company’s previously announced $1.2 billion share buyback program is expected to begin on Monday, February 26, 2024.

Total net sales ($ million)	3,198		3,095		3	%	3,466			(8	%)
Operating income ($ million)	780		841		(7	%)	980			(20	%)
Operating margin (% of sales)	24.4	%	27.2	%			28.3		%

Net sales of tubular products and services increased 3% sequentially but declined 8% year on year. Volumes increased 10% sequentially but average selling prices decreased 6%. In North America, sales decreased 12% sequentially reflecting lower prices and a decline in activity in the U.S. onshore market. In South America sales decreased 3% sequentially, mainly due to lower prices of OCTG in Argentina. In Europe sales increased 30% sequentially due to higher sales for offshore line pipe products in Norway. In the Asia Pacific, Middle East and Africa sales increased 45% reflecting higher sales in Saudi Arabia and for offshore line pipe projects in Qatar and sub-Saharan Africa.

Operating income from tubular products and services, amounted to $780 million in the fourth quarter of 2023, compared to $841 million in the previous quarter and $980 million in the fourth quarter of 2022. During the quarter the operating margin decreased following a 6% decrease in average selling prices only partially compensated by a decrease in average tubes cost of 4%.

Others	4Q 2023		3Q 2023				4Q 2022
Net sales ($ million)	217		143		52	%	154		41	%
Operating income ($ million)	39		27		45	%	33		19	%
Operating margin (% of sales)	18.1	%	19.0	%			21.4	%

Net sales of other products and services increased 52% sequentially and 41% year on year. The sequential increase is mainly explained by the consolidation of sales in December 2023 of the newly acquired coating business which contributed $77 million, largely related to a major project in Altamira, Mexico.

Selling, general and administrative expenses, or SG&A, amounted to $471 million (13.8% of net sales), compared to $433 million (13.4%) in the previous quarter and $454 million (12.6%) in the fourth quarter of 2022. The increase in SG&A is mainly related to higher labor costs and the integration of the newly acquired coating business headcount and amortizations.

Other operating result amounted to a $5 million loss in the fourth quarter of 2023, compared with a $36 million gain in the previous quarter and a $12 million loss in the fourth quarter of 2022. The previous quarter gain was mainly related to a non-recurring gain of $32 million corresponding to the transfer of court awards related to the Company’s Venezuelan nationalized assets.

Financial results were a gain of $93 million in the fourth quarter of 2023, compared with a gain of $67 million in the previous quarter and a gain of $36 million in the fourth quarter of 2022. Results of the quarter are mainly derived from net foreign exchange gains of $144 million, mainly related to the positive effect of the devaluation of the Argentine peso over a net short exposure in that currency. This positive FX results were partially offset by $95 million loss from the change in the fair value of U.S. dollar-denominated Argentine bonds when distributed and disposed abroad. Additionally, our net cash position yield a net interest gain of $44 million in the quarter.

Equity in earnings of non-consolidated companies generated a gain of $57 million in the fourth quarter of 2023, compared to a loss of $110 million in the previous quarter and a gain of $13 million in the same period of 2022. The result of the previous quarter included a non-cash loss of $144 million from our investment in Usiminas.

Income tax result amounted to a gain of $177 million in the fourth quarter of 2023, compared to a charge of $278 million in the previous quarter and $258 million in the fourth quarter of 2022. The gain of the quarter is mainly explained by: i) the recognition of a deferred tax asset of $550 million as a result of new business activities to be carried out at subsidiaries with tax loss carry forwards, ii) a $190 million deferred tax liability recognized mainly related to foreign exchange devaluation in Argentina, due to the decline of the fiscal values related to fixed assets and inventory.

Cash Flow and Liquidity of 2023 Fourth Quarter

Net cash provided by operations during the fourth quarter of 2023 was $836 million, compared with $1,297 million in the previous quarter and $524 million in the fourth quarter of 2022. Working capital during the quarter increased by $66 million, mainly due to the increase in trade receivables, however operating working capital days declined to 134 at year end compared to 138 at the end of the previous quarter.

With capital expenditures of $167 million for the fourth quarter of 2023 ($170 million in the previous quarter and $108 million in the fourth quarter of 2022), during the quarter we had a positive free cash flow of $669 million. Additionally, during the quarter we paid $161 million (net of cash) for the acquisition of Mattr’s pipe coating business unit.

Following dividend payments of $235 million and share buybacks of $214 million during the quarter, our positive net cash position increased to $3.4 billion at December 31, 2023.

Volumes increased mainly in the AMEA region following the increase in activity and in South America mainly due to the delivery of welded line pipe for a gas pipeline in Argentina. Prices were higher in all regions.

Operating results from tubular products and services, amounted to a gain of $4,183 million in 2023, compared to a gain of $2,867 million in 2022 (which was net of a $63 million impairment charge). The improvement in operating results was driven by the recovery in shipment volumes and in prices which help to compensate the increase in costs.

Additionally, in 2023 we had higher sales from our oilfield services business in Argentina, sucker rods and coiled tubing services, which offset the decline in sales of excess raw materials and energy and pipes for plumbing applications in Italy.

Financial results amounted to a gain of $221 million in 2023, compared to a loss of $6 million in 2022. 2023 results are mainly derived from net foreign exchange gains of $209 million, mainly related to the positive effect of the devaluation of the Argentine peso over a net short exposure in that currency. These positive FX results were partially offset by a $95 million loss from the change in the fair value of U.S. dollar-denominated Argentine bonds when distributed and disposed abroad. Additionally, our net cash position yield a net interest gain of $107 million in the year.

Equity in earnings of non-consolidated companies generated a gain of $95 million in 2023, compared to $209 million in 2022. These results were mainly derived from our equity investment in Ternium (NYSE:TX). The result of 2023 includes a non-cash loss of $144 million from our investment in Usiminas ($26 million from our direct investment in Usiminas and $118 million from our indirect investment in Usiminas through Ternium), related to the fair value measurement of the shares and the result of recycling Ternium´s negative accumulated currency translation reserve to the income statement. In 2022 they included $34 million impairment charges on our participations in the joint venture with Severstal ($15 million) and in Usiminas ($19 million).

Income tax charge amounted to $675 million in 2023, compared to $617 million in 2022, reflecting the improvement in results in several subsidiaries and a net positive deferred tax effect of $194 million.

Exhibit I – Alternative performance measures

Alternative performance measures should be considered in addition to, not as substitute for or superior to, other measures of financial performance prepared in accordance with IFRS.

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 recurring 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 = Net income for the period + Income tax charges +/- Equity in Earnings (losses) of non-consolidated companies +/- Financial results + Depreciation and amortization +/- Impairment charges/(reversals)

EBITDA is a non-IFRS alternative performance measure.

	2023		2022		2023		2022
Income for the period	1,145,781		803,172		3,957,833		2,548,701

EBITDA	975,310		1,268,911		4,864,918		3,647,723

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.

Free cash flow is a non-IFRS alternative performance measure.

(all amounts in thousands of U.S. dollars)	Three-month period ended December 31,				Twelve-month period ended December 31,
	2023		2022		2023		2022
Net cash provided by operating activities	835,735		523,942		4,395,073		1,167,217
Capital expenditures	(166,820	)	(107,646	)	(619,445	)	(378,446	)
Free cash flow	668,915		416,296		3,775,628		788,771

Net Cash / (Debt)

This is the net balance of cash and cash equivalents, other current investments and fixed income investments held to maturity 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 and Non-Current)+/- Derivatives hedging borrowings and investments - Borrowings (Current and Non-Current).

Net cash/debt is a non-IFRS alternative performance measure.

(all amounts in thousands of U.S. dollars)	Year ended December 31,
	2023		2022
Cash and cash equivalents	1,637,821		1,091,527
Other current investments	1,969,631		438,448

Derivatives hedging borrowings and investments	-		6,480
Current borrowings	(535,133	)	(682,329	)
Non-current borrowings	(48,304	)	(46,433	)
Net cash / (debt)	3,422,235		921,267

Operating working capital days

Operating working capital is the difference between the main operating components of current assets and current liabilities. Operating working capital is a measure of a company’s operational efficiency, and short-term financial health.

Operating working capital days is calculated in the following manner:

Operating working capital days = [(Inventories + Trade receivables – Trade payables – Customer advances) / Annualized quarterly sales ] x 365

Operating working capital days is a non-IFRS alternative performance measure.
