Stillwater Mining Company Reports First Quarter 2014 Earnings

BILLINGS, MT -- (Marketwired - May 01, 2014) - STILLWATER MINING COMPANY (NYSE: SWC) (TSX: SWC.U)

• Consolidated net income attributable to common stockholders of $19.6 million or $0.15 per diluted share, an increase of 34.2% over the first quarter of 2013
• Mine production of 130,700 palladium and platinum ounces, an increase of 2.8% over the first quarter of 2013 and within guidance range
• All-in sustaining costs of $788 per mined ounce, compared to $845 per mined ounce for the first quarter of 2013, tracking ahead of guidance
• 101,500 ounces of recycled palladium, platinum and rhodium processed, down from 2013, primarily reflecting delays in deliveries due to weather related issues
• Corporate overhead reduced to $10.8 million, down 53% from the first quarter of 2013
• Cash and highly liquid investments totaling $474.3 million at March 31, 2014

Stillwater Mining Company today reported 2014 first quarter consolidated net income attributable to common stockholders of $19.6 million or $0.15 per diluted share, compared to 2013 first quarter consolidated net income attributable to common stockholders of $14.6 million or $0.12 per diluted share. The 34.2% increase in earnings has been achieved despite realized metal prices being 2% lower than in the corresponding period of 2013, primarily reflecting the Company's cost reduction efforts.

Commenting on the first quarter results, Mick McMullen, the Company's President and Chief Executive Officer stated, "I am pleased with our start to the year. Mined production was good and within our guidance range, while costs were below guidance. There was a drop in recycling volumes in part reflecting issues with the harsh winter weather, but shipments have picked up as the weather has improved. Very importantly, our team is focusing on productivity and cost control. Our corporate overhead costs were down sharply from last year and we reported all-in sustaining costs of $788 per ounce for the quarter, which is below last year and the low end of our previous guidance range. Total capital expenditures of about $25 million were incurred, which was also below guidance. Based on these results and current forecasts we are improving our 2014 guidance for all-in sustaining costs (a non-GAAP measure) to a range of $800 to $850 per mined ounce and reducing our total cash cost per mined ounce guidance (net of credits for by-products and recycling) to a range of $530 to $570. We are also decreasing our full-year 2014 capital expenditure guidance to a range of $130 to $140 million. In addition, we have established a longer term goal to reduce our all-in sustaining cash costs per ounce by circa $100 below our 2013 results, taking our all-in sustaining costs to the low $700's per ounce."

For the first quarter of 2014, the Company's Montana mines produced a total of 130,700 ounces of palladium and platinum, a 2.8% increase compared to mine production of 127,100 ounces in the first quarter of 2013. The 18.8% increase in East Boulder Mine production in this year's first quarter compared to the first quarter of 2013 was driven by slightly higher realized ore grades and higher tons mined. The 3.0% decline in ounces produced at the Stillwater Mine reflected lower ore tons mined and increased allocation of resources to development activities during the 2014 first quarter compared to the first quarter of 2013.

Revenue from the Company's Mine Production segment for the first quarter of 2014 (including proceeds from the sale of by-products) totaled $125.7 million, a 2.0% decrease from $128.3 million in the same period of 2013. Combined sales realizations for mined palladium and platinum decreased for the first quarter of 2014, averaging $907 per mined ounce, compared to $926 per mined ounce realized in the first quarter of 2013. The total quantity of mined palladium and platinum ounces sold in the first quarter of 2014 was 131,300 ounces compared to 130,400 ounces sold in the same period of 2013. As a result of earlier constraints on reprocessing slag inventories at the Stillwater Mine, the Company now expects the benefit of PGMs resident in its slag inventories at the end of 2013 to be realized in second quarter 2014 sales.

The Company processed recycling material containing 101,500 ounces of palladium, platinum and rhodium through its smelter and refinery during the first quarter of 2014. This represents a decrease of 34.2% over the total of 154,200 ounces processed during the first quarter of 2013. As noted, the decrease in recycling volumes during the first quarter of 2014 was primarily due to weather related issues. Recycling material deliveries have increased subsequent to the end of the first quarter as overall weather conditions have improved.

Recycling sales volumes for the first quarter of 2014 decreased by 20.0%, to 93,500 ounces from 116,900 ounces sold in the first quarter of 2013. PGM Recycling revenue totaled $93.5 million for the 2014 first quarter, a 23.5% decrease from $122.3 million in the same period of 2013. The Company's combined average realized price for sales of recycled palladium, platinum and rhodium decreased by 6% to $980 per ounce in the first quarter of 2014 from $1,043 per ounce in the first quarter of 2013.

Combined total cash costs per mined ounce, net of by-product and recycling credits, (a non-GAAP measure) averaged $568 per ounce for the quarter ended March 31, 2014. See - "Reconciliation of Non-GAAP Measures to Consolidated Costs of Revenues." The table below illustrates the effect of by-product and recycling credits on the total cash costs per mined ounce net of credits for the combined Montana mining operations.

The Company is also utilizing another, broader non-GAAP measure of mining efficiency, All-in Sustaining Cost, in monitoring and managing its performance going forward. This non-GAAP measure starts with total cash costs net of credits and adds back the recycling credit, plus U.S. corporate general and administrative costs (before depletion, depreciation and amortization) and capital outlays directed toward sustaining operations at the Company's operating mines. The resulting measure provides a comparative indication of the all-in resources consumed in any period to sustain the mining operations and produce at current levels.

Cash Flow and Liquidity

At March 31, 2014, the Company's consolidated available cash balance was $224.6 million, compared to $286.7 million at December 31, 2013. If highly liquid investments are included with available cash, the Company's balance sheet liquidity totaled $474.3 million at March 31, 2014, a decrease from $496.0 million at December 31, 2013. Essentially all of this decline in total balance sheet liquidity was attributable to a $19.9 million increase in accounts receivable at quarter end, reflecting a larger than normal share of sales revenue that was not collected until the first week of April. Of the Company's first quarter consolidated cash balance, $20.4 million is dedicated to the Marathon project (and other related Canadian properties) and is unavailable for other corporate purposes. Net working capital -- comprised of total current assets (including available cash and investments), less current liabilities -- increased to $628.0 million at March 31, 2014, from $614.8 million at the end of 2013.

Net cash provided by operating activities (which includes changes in working capital) totaled $4.8 million for the quarter ended March 31, 2014, compared to $15.5 million of cash provided for the same period of 2013. As noted above, most of this working capital change reflects the growth in accounts receivable resulting from the mix of customers paying during the first week of April instead of the last week of March. Capital expenditures, adjusted to a cash basis, were $26.1 million for the quarter ended March 31, 2014, compared to $29.4 million in the same period of 2013.

Outstanding debt at March 31, 2014, was $314.3 million, up from $310.7 million at December 31, 2013. The Company's reported debt balance currently includes approximately $278.2 million of 1.75% convertible debentures (net of unamortized discount of $118.6 million) and $2.2 million of 1.875% convertible debentures, $29.6 million of exempt facility revenue bonds, a capital lease of $4.1 million and approximately $0.2 million of financing for a small installment land purchase. The increase in the debt balance during 2014 is attributable to the accretion of the discount on the Company's outstanding bonds.

Other Matters

The Company continues to focus heavily on the efficient allocation of resources, with numerous initiatives underway to arrest and reduce rising costs experienced historically. Examples include evaluating more efficient alternatives for transporting employees and materials within the expanding underground mine infrastructure, improving material procurement methods to ensure the lowest costs are achieved and assessing the economics of the various mining areas to ensure each ounce of production is profitable. During 2014 the Company has initiated a restructuring process that has impacted positions at various levels within the organization. This restructuring was initiated as part of the ongoing effort to ensure a long-term sustainable business. Positions at the Company's Montana operations and at its Marathon and Altar project locations in Canada and Argentina, respectively, were affected. This action included the reduction of 48 salaried personnel and the opportunity for up to an additional 50 voluntary separations for the hourly workforce. As a result, it is estimated that restructuring costs of $4.3 million will be recognized in the second quarter of 2014 for the salaried positions and additional expenses associated with the voluntary separations that have not been finalized at this time.

The Company has scaled back its activities at Altar, its copper-gold prospect in Argentina, while determining how best to realize value from the property going forward. In the meantime, the Company is maintaining a minimum level of activity that permits it to retain its interest in the Altar concessions while limiting spending to essential services. The Company recently reached an agreement with IPEEM, the Argentine entity that granted the Rio Cenicero mineral leases at Altar, to renew the Company's exploration concessions there through August 2015.

The Company owns a 75% interest in the Marathon PGM-copper project and related properties in Canada. Mitsubishi Corporation owns the remaining 25%. As announced during the first quarter of this year, it has become clear that at current PGM and copper prices, the project as presently conceived would not provide an acceptable economic rate of return for shareholders. The Company and its partner are examining various alternatives to enhance project returns. However, at this time there is no assurance that these alternatives will provide the economic improvement to make the project viable. Several of these changes, if implemented, could result in changes to the project scope that are not contemplated in the current economic assessment process. Consequently, the Company agreed with the joint environmental review panel that is addressing the Marathon project to suspend the review process until there is further clarity as to the direction of the project. The Company is maintaining its position at Marathon and looking for opportunities to realize value there in the future. However, until such time as the project is able to demonstrate viable economics, the Company is scaling back spending on the Marathon project.

First Quarter Results - Details

For the first quarter of 2014, the Company's Stillwater Mine produced 89,700 ounces of palladium and platinum, a decrease of 3.1% from the 92,600 ounces produced in the first quarter of 2013. Production at the Company's East Boulder Mine of 41,000 ounces in the first quarter of 2014 reflected an increase of 18.8% over the 34,500 ounces produced in the same quarter of 2013.

Costs of metals sold (before depletion, depreciation and amortization expense) decreased to $168.8 million in the first quarter of 2014 from $192.6 million in the first quarter of 2013. Mine Production costs included in costs of metals sold increased to $78.0 million in the 2014 first quarter from $75.8 million in the 2013 first quarter. PGM Recycling costs, which primarily reflect the cost of acquiring spent catalytic materials for processing, totaled $90.7 million in the first quarter of 2014, down from the $116.9 million reported in the first quarter of 2013.

General and administrative costs were $9.6 million in the first quarter of 2014, down from the $15.2 million incurred during the same period of 2013. The higher G&A costs in the first quarter of 2013 reflected additional legal and advisory fees of approximately $2.8 million in connection with the proxy contest as well as higher compensation benefits of approximately $2.0 million. Exploration expenses were $1.0 million in the first quarter of 2014 compared to $6.0 million in the same period of 2013 as a result of steps taken to scale back exploration at the Altar and Marathon projects. Marketing expenses declined to $0.2 million in the 2014 first quarter compared to $1.7 million in the same quarter of 2013, reflecting the curtailment of palladium jewelry marketing efforts.

Interest expense reported for the first quarter of 2014 and 2013 was $5.9 million and $6.7 million, respectively. This decrease is due in part to the paying down on the outstanding debt associated with the 1.875% convertible early in the first quarter of 2013, offset in part by interest expense related to the 1.75% convertible debentures, including the accretion of the debt discount that is charged to earnings over the expected life of the convertible debentures. Interest expense also is reduced by capitalized interest accrued on the Company's ongoing projects.

During the first quarter of 2014, the Company recorded a net foreign currency transaction gain of $4.2 million, primarily related to the deferred tax liability recorded in association with the acquisition of Peregrine Metals Ltd. The net foreign currency transaction gain recorded for the first quarter of 2013 was flat with the current year's first quarter at $4.2 million.

(1) Ounces sold and average realized price per ounce from PGM Recycling
    relate to ounces produced from processing of catalyst materials.

(2) By-product metals sold reflect contained metal produced from mined ore
    alongside the Company's primary production of palladium and platinum.
    Realized prices reflect net values (discounted due to product form and
    transportation and marketing charges) per unit received.

(3) The Company's average realized price represents revenues, which include
    the effect of hedging gains and losses realized on commodity instruments
    and agreement discounts, divided by ounces sold. The average market
    price represents the average London Bullion Market Association afternoon
    postings for the actual months of the period.

(4) The Company calculates the combined average realized and a combined
    average market price of palladium and platinum using the same ratio as
    the rate of ounces of each respective metal that are produced from the
    base metal refinery.

Reconciliation of Non-GAAP Measures to Consolidated Costs of Revenues

The Company utilizes certain non-GAAP measures as indicators in assessing the performance of its mining and processing operations during any period. Because of the processing time required to complete the extraction of finished PGM products, there are typically lags of one to three months between ore production and sale of the finished product. Sales in any period include some portion of material mined and processed from prior periods as the revenue recognition process is completed. Consequently, while costs of revenues (a GAAP measure included in the Company's Consolidated Statements of Comprehensive Income) appropriately reflects the expense associated with the materials sold in any period, the Company has developed certain non-GAAP measures to assess the costs associated with its producing and processing activities in a particular period and to compare those costs between periods.

While the Company believes that these non-GAAP measures may also be of value to outside readers, both as general indicators of the Company's mining efficiency from period to period and as insight into how the Company internally measures its operating performance, these non-GAAP measures are not standardized across the mining industry and in most cases will not be directly comparable to similar measures that may be provided by other companies. These non-GAAP measures are only useful as indicators of relative operational performance in any period, and because they do not take into account the inventory timing differences that are included in costs of revenues, they cannot meaningfully be used to develop measures of earnings or profitability. A reconciliation of these measures to costs of revenues, the most comparable measure under GAAP, for each period shown is provided as part of the following tables, and a description of each non-GAAP measure is provided below.

Total Consolidated Costs of Revenues: For the Company as a whole, this measure is equal to total costs of revenues, as reported in the Consolidated Statements of Comprehensive Income. For the Stillwater Mine, the East Boulder Mine, and other PGM activities, the Company segregates the expenses within total costs of revenues that are directly associated with each of these activities and then allocates the remaining facility costs included in total cost of revenues in proportion to the monthly volumes from each activity. The resulting total costs of revenues measures for the Stillwater Mine, the East Boulder Mine and other PGM activities are equal in total to total consolidated costs of revenues as reported in the Company's Consolidated Statements of Comprehensive Income.

Total Cash Costs (Non-GAAP): This non-GAAP measure is calculated as total costs of revenues (for each mine or combined) adjusted to exclude gains or losses on asset dispositions, costs and profit from recycling activities, revenues from the sale of mine by-products, depreciation and amortization and asset retirement costs, and timing differences resulting from changes in product inventories. The Company uses this measure as a comparative indication of the cash costs related to production and processing operations in any period. It is a measure of extraction efficiency.

When divided by the total tons milled in the respective period, Total Cash Cost per Ton Milled (Non-GAAP) -- measured for each mine or combined -- provides an indication of the level of cash costs incurred per ton milled in that period. Because of variability of ore grade in the Company's mining operations, production efficiency underground is frequently measured against ore tons produced rather than contained PGM ounces. Because ore tons are first weighed as they are fed into the mill, mill feed is the first point at which production tons are measured precisely. Consequently, Total Cash Cost per Ton Milled (Non-GAAP) is a general measure of production efficiency, and is affected both by the level of Total Cash Costs (Non-GAAP) and by the volume of tons produced and fed to the mill.

When divided by the total recoverable PGM ounces from production in the respective period, Total Cash Cost per Ounce (Non-GAAP) -- measured for each mine or combined -- provides an indication of the level of cash costs incurred per PGM ounce produced in that period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because ultimately extracting PGM material is the objective of mining, the cash cost per ounce of extracting and processing PGM ounces in a period is a useful measure for comparing extraction efficiency between periods and between the Company's mines. Consequently, Total Cash Cost per Ounce (Non-GAAP) in any period is a general measure of extraction efficiency, and is affected by the level of Total Cash Costs (Non-GAAP), by the grade of the ore produced and by the volume of ore produced in the period.

Stillwater Mining Company
All-In Sustaining Cost a Non-GAAP Measure
(Unaudited)

All-In Sustaining Costs (Non-GAAP): This non-GAAP measure is used as an indicator from period to period of the level of total cash required by the business to maintain and operate the existing mines, including corporate administrative costs and replacement capital. The measure is calculated beginning with total cash costs (another non-GAAP measure, described above), and adding to it the recycling income credit, corporate overhead costs (excluding any depreciation and amortization costs and other non-recurring non-cash costs included in corporate overhead costs), marketing costs, and that portion of total capital expenditures associated with sustaining the current level of mining operations.

When divided by the total recoverable PGM ounces in the respective period, All-In Sustaining Costs per Mined Ounce (non-GAAP) provides an indication of the level of total cash required to maintain and operate the mines per PGM ounce produced in the period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because the objective of PGM mining activity is to extract PGM material, the all-in cash cost per ounce to produce PGM material, administer the business and sustain the operating capacity of the mines is a useful measure for comparing overall extraction efficiency between periods. This measure is affected by the total level of spending in the period and by the grade and volume of ore produced.
