Ferroglobe Reports Solid Fourth Quarter and Full Year 2023 Financial Results

LONDON, February 21, 2024 (GLOBE NEWSWIRE) – Ferroglobe PLC (NASDAQ: GSM) (“Ferroglobe”, the “Company”, or the “Parent”), a leading producer globally of silicon metal, silicon-based and manganese-based specialty alloys, today announced financial results for the fourth quarter and full year 2023.

Introducing 2024 adjusted EBITDA guidance of $100 million to $170 million

FINANCIAL HIGHLIGHTS

●

2023 revenue of $1.7 billion, down 36% Y/Y

●

2023 adjusted EBITDA of $315 million, down 63% Y/Y

●

Q4 adjusted EBITDA declined to $60 million, down 42% from Q3 and down 54% from Q4-22

●

Q4 adjusted EBITDA margins were at 16% versus 25% in the prior quarter and 29% in Q4-22

●

Q4 adjusted EPS was $0.09 versus $0.27 in Q3 and $0.39 in Q4-22

●

Net debt increased to $101 million, up from $71 million in Q3 and down from $127 million in Q4-22

●

Total cash decreased to $138 million, down from $166 million in Q3 and $323 million in Q4-22

BUSINESS HIGHLIGHTS

●	Posted solid financial and operational performance for the quarter and the full year despite softening demand and weak pricing

●	Adjusted gross debt remained flat in Q4; declining to less than $100 million in February as a result of a $148 million redemption on February 16, 2024

●	Initiated a quarterly cash dividend of $0.013 per share, payable on March 28, 2024 to shareholders of record as of the close of business on March 22, 2024

●	Expecting to request the board of directors and shareholders to approve a share repurchase program

●	Optimized French energy contract to drive strong results in 2023, received majority of related cash in 2024

●	Signed a term sheet for a partnership with a leading battery materials company in Europe and a memorandum of understanding with an advanced silicon-rich EV battery technology company in the US

Dr. Marco Levi, Ferroglobe’s Chief Executive Officer, commented, “2023 was a successful year for Ferroglobe with strong financial, operating and strategic performance as we significantly reduced our debt, acquired a strategic quartz mine and entered into two EV battery agreements while operating our plants at high efficiency levels. This strong performance enabled us to announce a capital return policy today, with the board declaring a quarterly dividend of $0.013 per share and we expect to announce a share repurchase program in the coming months.

“Despite the current softness in our end markets, we are very bullish about the company’s long-term prospects as we expect strong secular growth in the solar and EV battery markets to boost the demand for silicon metal in the coming years. We have positioned Ferroglobe to fully participate in these growth opportunities as the leading western producer of silicon metal.

“We are introducing 2024 adjusted EBITDA guidance of $100 million to $170 million. Demand remains soft in early 2024, and while the recent increases in index prices are positive, we believe they have been partially driven by supply chain disruptions. We anticipate an improving demand picture in the second half of the year,” concluded Dr. Levi.

Sales

In the fourth quarter of 2023, Ferroglobe reported net sales of $376 million, a decrease of 10% over the prior quarter and a decrease of 16% over the year-ago period. For the full year 2023, sales were $1.7 billion versus $2.6 billion in the prior year, a decrease of 36%. The decrease in our fourth quarter results is primarily attributable to lower volumes across our product portfolio and lower pricing of our main products. The $41 million decrease in sales over the prior quarter was primarily driven by silicon metal, which accounted for $31 million of the decrease, and silicon-based alloys, which accounted for $8 million. These decreases were partially offset by manganese-based alloys, which increased by $1 million. The decrease in sales for the full year 2023 was mainly driven by a significant decrease in prices and volumes across all the products.

Raw materials and energy consumption for production

Raw materials and energy consumption for production was $200 million in the fourth quarter of 2023 versus $196 million in the prior quarter, an increase of 2%. As a percentage of sales, raw materials and energy consumption for production was 53% in the fourth quarter of 2023 versus 47% in the prior quarter. This variance was mainly due to lower energy compensation in France. For the full-year 2023, raw materials and energy consumption for production were $880 million, or 53% of sales, versus $1,285 million, or 49% of sales in 2022. The increase in these costs as a percent of sales was driven by lower pricing.

Net Income (Loss) Attributable to the Parent

In the fourth quarter of 2023, net loss attributable to the parent was $6 million, or ($0.03) per diluted share, compared to a net profit attributable to the parent of $41 million, or $0.21 per diluted share in the third quarter. For the full year 2023, net profit attributable to the parent was $87 million, or $0.46 per diluted share, compared to $440 million, or $2.32 per diluted share.

Adjusted EBITDA

In the fourth quarter of 2023, adjusted EBITDA was $60 million, or 16% of sales, a decrease of 42% compared to adjusted EBITDA of $104 million, or 25% of sales in the third quarter of 2023. The decrease in the fourth quarter of 2023 adjusted EBITDA as a percentage of sales is primarily attributable to a decrease in sales volumes and prices.

For the full year 2023, adjusted EBITDA was $315 million, or 19% of sales, compared to adjusted EBITDA of $860 million, or 33% of sales, for the full year 2022.

Total Cash

The total cash balance was $138 million as of December 31, 2023, down $28 million from $166 million as of September 30, 2023. During the year, the total cash balance declined by $185 million, mainly due to the partial redemption of senior secured notes in July 2023.

During the fourth quarter of 2023, we generated positive operating cash flow of $25 million, had negative cash flow from investing activities of $23 million, and $30 million in negative cash flow from financing activities. For the full year 2023, we generated positive operating cash flow of $175 million, had negative cash flow from investing activities of $82 million and $279 million in negative cash flow from financing activities.

Total Working Capital

Total working capital was $511 million as of December 31, 2023, a slight increase from $510 million on September 30, 2023. The increase in working capital during the quarter was primarily due to an increase in trade and other receivables of $17 million and an increase in inventories by $1 million, partially offset by a $17 million increase in trade and other payables.

Beatriz García-Cos, Ferroglobe’s Chief Financial Officer, commented, “After reducing our working capital by $154 million in 2023, achieving a positive net cash position at the end of January this year was a significant milestone for Ferroglobe. Our strong cash generation allowed us to redeem the remaining Senior Secured Notes last week, enabling us to initiate a capital return policy. Our hybrid program includes a declaration of a quarterly dividend of $0.013 per share, while we expect to initiate a discretionary share repurchase plan in the coming months.

“After generating $93 million of free cash flow in 2023, we anticipate generating positive free cash in 2024, despite the soft demand we are currently facing. Our balance sheet is the strongest it has been in the Company’s history, and we have right-sized our capital structure systematically over the past year and a half,” concluded Mrs. García-Cos.

Silicon-based alloy revenue in the fourth quarter was $107 million, a decrease of 7.0% over the prior quarter. The average realized selling price decreased by 7.1%, due to lower demand for ferrosilicon linked to general industry declines in the steel sector. Total shipments of silicon-based alloys were flat relative to the prior quarter. Adjusted EBITDA for the silicon-based alloys portfolio increased to $35 million in the fourth quarter of 2023 compared to $25 million for the prior quarter. Adjusted EBITDA margin increased in the quarter mainly due to improved costs.

Implemented a Capital Return Policy

The board of directors declared a quarterly cash dividend of $0.013 per share, payable on March 28, 2024 to shareholders of record as of the close of business on March 22, 2024. We intend to make this a recurring quarterly dividend, subject to board approval, and may be adjusted depending on market conditions and other factors. In addition, we are planning to request our board of directors to approve the initiation of a share repurchase program, which requires a shareholder vote as a UK company listed on Nasdaq.

Forward-Looking Statements and non-IFRS Financial Metrics 2 This presentation contains forward-looking statements within the meaning of Section 27A of the United States Securities Act of 1933, as amended, and Section 21E of the United States Securities Exchange Act of 1934, as amended. Forward-looking statements are not historical facts but are based on certain assumptions of management and describe our future plans, strategies and expectations. Forward-looking statements can generally be identified by the use of forward-looking terminology, including, but not limited to, "may," “could,” “seek,” “guidance,” “predict,” “potential,” “likely,” "believe," "will," "expect," "anticipate," "estimate," "plan," "intend," "forecast," “aim,” “target,” or variations of these terms and similar expressions, or the negative of these terms or similar expressions. Forward-looking statements contained in this presentation are based on information presently available to Ferroglobe PLC (“we,” “us,” “Ferroglobe,” the “Company” or the “Parent”) and assumptions that we believe to be reasonable, but are inherently uncertain. As a result, our actual results, performance or achievements may differ materially from those expressed or implied by these forward-looking statements, which are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors that are, in some cases, beyond our control. You are cautioned that all such statements involve risks and uncertainties, including without limitation, risks that Ferroglobe will not successfully integrate the businesses of Globe Specialty Metals, Inc. and Grupo FerroAtlántica SAU, that we will not realize estimated cost savings, value of certain tax assets, synergies and growth, and/or that such benefits may take longer to realize than expected. Important factors that may cause actual results to differ include, but are not limited to: (i) risks relating to unanticipated costs of integration, including operating costs, customer loss and business disruption being greater than expected; (ii) our organizational and governance structure; (iii) the ability to hire and retain key personnel; (iv) regional, national or global political, economic, business, competitive, market and regulatory conditions including, among others, changes in metals prices; (v) increases in the cost of energy and other raw materials; (vi) competition in the metals and foundry industries; (vii) environmental and regulatory risks; (viii) ability to identify liabilities associated with acquired properties prior to their acquisition; (ix) ability to manage operational risks including industrial accidents and natural disasters; (x) ability to manage a global footprint; (xi) changes in technology; (xii) ability to acquire or renew permits and approvals; (xiii) changes in legislation or governmental regulations affecting Ferroglobe; (xiv) conditions in the credit markets; (xv) risks associated with assumptions made in connection with critical accounting estimates and legal proceedings; (xvi) Ferroglobe's international operations, which are subject to the risks of currency fluctuations and foreign exchange controls; and (xvii) the potential of international unrest, economic downturn or effects of currencies, tax assessments, tax adjustments, anticipated tax rates, raw material costs or availability or other regulatory compliance costs. The foregoing list is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that affect our business, including those described in the “Risk Factors” section of our, Annual Reports on Form 20-F, Current Reports on Form 6-K and other documents we file from time to time with the United States Securities and Exchange Commission. We do not give any assurance (1) that we will achieve our expectations or (2) concerning any result or the timing thereof, in each case, with respect to any regulatory action, administrative proceedings, government investigations, litigation, warning letters, consent decree, cost reductions, business strategies, earnings or revenue trends or future financial results. Forward- looking financial information and other metrics presented herein represent our key goals and are not intended as guidance or projections for the periods presented herein or any future periods. We do not undertake or assume any obligation to update publicly any of the forward-looking statements in this presentation to reflect actual results, new information or future events, changes in assumptions or changes in other factors affecting forward-looking statements. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements. We caution you not to place undue reliance on any forward-looking statements, which are made only as of the date of this presentation. Adjusted EBITDA, adjusted EBITDA margin, adjusted net profit, adjusted profit per share, working capital, adjusted gross debt and net debt, are non-IFRS financial metrics that, we believe, are pertinent measures of Ferroglobe’s success. The Company has included these financial metrics to provide supplemental measures of its performance. We believe these metrics are important because they eliminate items that have less bearing on the Company’s current and future operating performance and highlight trends in its core business that may not otherwise be apparent when relying solely on IFRS financial measures. For additional information, including a reconciliation of the differences between such non-IFRS financial measures and the comparable IFRS financial measures, refer to the press release dated February 21, 2024 accompanying this presentation, which is incorporated by reference herein.
