CHICAGO – August 9, 2016 – Ryerson Holding Corporation (NYSE: RYI), a leading distributor and processor of metals, today reported results for the second quarter of 2016.

“Our second quarter results are a clear and continuing demonstration of the strength of our strategy and quality of our execution”, said Ryerson’s President and Chief Executive Officer Eddie Lehner. “We made significant improvements to our balance sheet while gaining market share, expanding margins, controlling costs and increasing inventory velocity. I want to thank each and every Ryerson teammate for their excellent work, as our passion for creating great customer experiences burns brighter every day.”

Second Quarter 2016 Results

Revenues were $739.8 million for the second quarter of 2016, down 12.0 percent from the year-ago period due to a 14.9 percent decline in the average selling price per ton. Tons shipped increased 3.5 percent, compared to a decline of 5.3 percent for the industry, as measured by Metals Service Center Institute (MSCI) results. Sequentially, revenues increased 5.3 percent from the first quarter of 2016. The 0.3 percent decline in the average selling price per ton was more than offset by a 5.6 percent increase in tons shipped, which compared favorably to the industry, which increased 2.0 percent.

Gross margin was 22.0 percent for the second quarter of 2016, compared to 19.7 percent for the year-ago period and 21.0 percent in the first quarter of 2016. Included in cost of materials sold was net LIFO income of $7.0 million for the second quarter of 2016, $37.0 million for second quarter of 2015, and $14.8 million for the first quarter of 2016. Gross margin, excluding LIFO was 21.1 percent for the second quarter of 2016, an expansion of 580 basis points from the second quarter of 2015, and 220 basis points higher than the first quarter of 2016. A reconciliation of gross margin, excluding LIFO to gross margin is included below in this news release.

Warehousing, delivery, selling, general and administrative expense declined $1.1 million, or 1.0 percent, year-over-year. Sequentially, warehousing delivery, selling, general and administrative expense increased $3.8 million, or 3.5 percent, due to higher volume and associated variable expenses.

Net income attributable to Ryerson Holding Corporation was $5.6 million, or $0.17 per diluted share, for the second quarter of 2016, compared to $15.8 million, or $0.49 per diluted share, in the second quarter of 2015 and $13.5 million, or $0.42 per diluted share in

the first quarter of 2016. Excluding impairment charges on assets and gains or losses on the retirement of debt, net income attributable to Ryerson Holding Corporation was $16.9 million, or $0.52 per diluted share, for the second quarter of 2016 compared to $17.2 million, or $0.54 per diluted share, for the second quarter of 2015 and $8.2 million, or $0.26 per diluted share, for the first quarter of 2016.

Balance Sheet Deleveraging and Working Capital Management

In May 2016, Ryerson issued $650 million of 11% Senior Secured Notes due 2022, redeemed all of the 9% Senior Secured Notes due in 2017 and repurchased $95 million of the 11.25% Senior Notes due in 2018. In July 2016, Ryerson issued 5,000,000 shares of common stock at a public offering price of $15.25 per share. Net proceeds of approximately $70.6 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by Ryerson, will be used to repurchase, redeem, defease or otherwise repay portions of Ryerson’s outstanding indebtedness, including but not limited to, the remaining 11.25% Senior Notes due 2018, from time to time.

“After the repurchase or redemption of the remaining 11.25% Senior Notes due 2018, expected to occur before the end of 2016, Ryerson will have no significant debt maturities until 2020,” stated Erich Schnaufer, Ryerson’s Chief Financial Officer. “Moreover, the debt and equity offerings enhance the company’s credit profile and will fund growth initiatives while putting us on the path to further deleverage our balance sheet.” A pro forma presentation of the net debt structure is included below in this news release.

In the second quarter of 2016, Ryerson’s inventory stood at 74 days of supply (DOS), compared to 76 days in the year-ago period.

First Six Months 2016 Results

Revenues for the first six months of 2016 were $1.4 billion, down 15.6 percent from the first six months of 2015, as a 2.0 percent increase in tons shipped was more than offset by a 17.2 percent decline in the average selling price per ton. Net income attributable to Ryerson Holding Corporation was $19.1 million, or $0.59 per diluted share, compared to $13.3 million, or $0.41 per diluted share, for the same period of 2015. Excluding impairment charges on assets and gains or losses on retirement of debt, earnings per diluted share were $0.78 in the first six months of 2016 compared to $0.70 for the same period of 2015.

Note: EBITDA represents net income before interest and other expense on debt, provision for income taxes, depreciation and amortization. Adjusted EBITDA gives further effect to, among other things, impairment charges on assets, reorganization expenses and foreign currency transaction gains and losses. We believe that the presentation of EBITDA, Adjusted EBITDA and Adjusted EBITDA, excluding LIFO expense (income), net, provides useful information to investors regarding our operational performance because they enhance an investor’s overall understanding of our core financial performance and provide a basis of comparison of results between current, past and future periods. We also disclose the metric Adjusted EBITDA, excluding LIFO expense (income), net, to provide a means of comparison amongst our competitors who may not use the same basis of accounting for inventories. EBITDA, Adjusted EBITDA and Adjusted EBITDA, excluding LIFO expense (income), net, are three of the primary metrics management uses for planning and forecasting in future periods, including trending and analyzing the core operating performance of our business without the effect of U.S. generally accepted accounting principles, or GAAP, expenses, revenues and gains (losses) that are unrelated to the day to day performance of our business. We also establish compensation programs for our executive management and regional employees that are based upon the achievement of pre-established EBITDA, Adjusted EBITDA and Adjusted EBITDA, excluding LIFO expense (income), net, targets. We also use EBITDA, Adjusted EBITDA and Adjusted EBITDA, excluding LIFO expense (income), net, to benchmark our operating performance to that of our competitors. EBITDA, Adjusted EBITDA and Adjusted EBITDA, excluding LIFO expense (income), net do not represent, and should not be used as a substitute for, net income or cash flows from operations as determined in accordance with generally accepted accounting principles, and neither EBITDA, Adjusted EBITDA and Adjusted EBITDA, excluding LIFO expense (income), net, is necessarily an indication of whether cash flow will be sufficient to fund our cash requirements. This release also presents gross margin, excluding LIFO expense (income), net, which is calculated as gross profit plus LIFO expense (or minus LIFO income), net, divided by net sales. We have excluded LIFO expense (income), net from the gross margin and Adjusted EBITDA as a percentage of net sales metrics in order to provide a means of comparison amongst our competitors who may not use the same basis of accounting for inventories as we do. Our definitions of EBITDA, Adjusted EBITDA, Adjusted EBITDA, excluding LIFO expense (income), net, gross margin, excluding LIFO expense (income), net, and Adjusted EBITDA, excluding LIFO expense (income), net, as a percentage of sales may differ from that of other companies.
