TEXT-S&P rates Stillwater Mining notes 'B'

Fri Oct 12, 2012 4:48pm EDT

Overview
     -- U.S.-based Stillwater Mining Co. has issued $345 million
convertible notes due 2032.
     -- We are affirming our 'B' corporate credit rating on Stillwater. We are 
assigning a 'B' issue rating and '3' recovery rating to the notes. 
     -- At the same time, we are lowering the rating on Stillwater's existing 
convertible notes to 'B' and are revising the recovery rating on the notes to 
'3'.
     -- The stable outlook reflects our view that Stillwater's credit metrics 
will remain in line with the 'B' corporate credit rating, in spite of higher 
debt and lower platinum group metals prices.

Rating Action
On Oct. 12, 2012, Standard & Poor's Ratings Services affirmed its 'B' 
corporate credit rating on Billings, Mont.-based mining operator Stillwater 
Mining Co. The outlook is stable.

At the same time, we assigned our 'B' issue-level rating (the same as the 
corporate credit rating) to the company's  $300 million convertible notes due 
2032. The recovery rating on the notes is '3', indicating our expectation for 
meaningful (50% to 70%) recovery in the event of payment default. We also 
lowered the rating on Stillwater's existing $166.5 million convertible notes 
to 'B' from 'B+' and revised the recovery rating on the notes to '3' from '2'.

We expect the company to use the proceeds from the issuance to repay principal 
that may come due under its existing convertible notes, which can be put to 
the company in March 2013, as well as for general corporate purposes.

Rationale
The rating affirmation follows Stillwater's announcement that it has issued 
$300 million new convertible notes due 2032. Despite higher pro forma debt 
balances (book debt will increase to about $500 million by year-end 2012 from 
$200 million at year-end 2011), we believe credit metrics will remain in line 
with the current rating, with debt-to-EBITDA of between 5x and 5.5x by 
year-end 2012 and funds from operations (FFO)-to-debt of around 15%. Assuming 
holders of the company's existing $166.5 million convertible notes exercise an 
option to put the notes back to the company, which they are eligible to do in 
March 2013, we expect leverage will decline to between 3x and 4x and for 
FFO-to-debt to rise above 20%.

Under our base-case scenario, we expect the company's 2012 production of 
platinum group metals (PGM) to decline to about 500,000 ounces from about 
515,000 ounces in 2011 because of changes in mining conditions, the allocation 
of manpower, and associated differences in mining productivities. We expect 
2013 production to remain in the range of 500,000 to 515,000 ounces. As a 
result of lower PGM prices and higher costs, we expect 2012 EBITDA of 
approximately $100 million, a significant decline from 2011's $220 million. 
Even if EBITDA remains around the same range in 2013, we expect leverage to 
improve to between 3x and 4x, from between 5x and 5.5x in 2012, because we 
expect investors will put the company's existing $166.5 million convertible 
notes back to the company. We consider these leverage ratios to be in line 
with the current rating.

The ratings on Stillwater reflect Standard & Poor's assessment of the 
company's business risk profile as "vulnerable" and financial risk profile as 
"aggressive." Stillwater is a small producer of palladium and platinum and 
recycles PGMs from auto catalysts. Our view of the company's profiles stems 
from Stillwater's very limited operating diversity, high cost profile, and 
exposure to volatile metals prices.

The rating also reflects our assessment that the company's mine development 
projects will require significant capital spending in the next two to three 
years. We expect that this will result in negative free cash flow and 
increased balance-sheet debt during this period. Our financial risk assessment 
incorporates the aggressive capital spending plan that Stillwater has in the 
near to intermediate term.

In addition, although Stillwater has made efforts to lower costs, in our view, 
they remain relatively high overall. This is due to the geology of the ore 
body and the company's difficulty in mining ores compared with its competitors 
that produce PGMs in higher quantities and as a byproduct of other metals. 
Because of increased development activities, lower overall mine production, 
and the effect on royalties and taxes of higher PGM prices, we expect cash 
costs to increase to $500 per ounce by the end of 2012 from $420 per ounce in 
2011. The increase in cash costs is primarily attributable to added labor in 
the miner training program, higher contractual wage and benefit rates, general 
inflation in supply costs, and lower mine production.

Liquidity
We view Stillwater's liquidity as "adequate" based on the following 
expectations:
     -- Liquidity sources (including cash and availability under its $125 
million asset-based lending {ABL} revolving credit facility) will exceed uses 
by at least 1.2x over the next year;
     -- Liquidity sources will continue to exceed uses, even if EBITDA were to 
decline by 15%; and
     -- The company would continue to exceed the availability threshold under 
its credit facility, even if EBITDA drops 15%.
 
Pro forma for the transaction, we expect between $400 million and $500 million 
of cash on the balance sheet by year end. We expect the company to use 
proceeds from the transaction to repay its existing $166.5 million convertible 
notes, which investors can put back to the company in March 2013. We also 
expect the company to have around $70 million of availability on its $125 
million ABL. Availability under the ABL facility is subject to a borrowing 
base of eligible receivables and inventory, and the facilities contain minimum 
fixed-charge covenants based on availability thresholds. Based on our current 
assumptions, we expect the company to maintain adequate liquidity and not 
trigger the fixed-charge covenants.

We expect free operating cash flow to be negative in 2012 and 2013 due to 
higher capital expenditures of between $150 million and $200 million for mine 
development projects. We do not anticipate that Stillwater will pay a dividend 
on its common stock in the foreseeable future. 

Stillwater's nearest maturity is March 2013, when its existing $166.5 million 
convertible notes become putable.

Recovery analysis
The rating on Stillwater's $345 million convertible notes and existing $166 
million convertible notes is 'B', the same as the corporate credit rating, and 
the recovery rating is '3', indicating our expectation for a meaningful (50% 
to 70%) recovery in the event of payment default. For the complete recovery 
analysis, please see the recover report on Stillwater, to be published on 
RatingsDirect shortly following the release of this report.

Outlook
The stable outlook reflects our expectation that Stillwater's credit metrics 
will remain in line with the 'B' corporate credit rating, in spite of higher 
debt and lower PGM prices. We expect the company's debt leverage to improve to 
between 3x and 4x in 2013 from a range of 5x to 5.5x in 2012 because we expect 
the company to repay its $166.5 million in existing convertible notes in March 
2013, when investors can put the notes back to the company. The rating is also 
supported by the company's liquidity, which we deem to be adequate. 

We could take a negative rating action if PGM prices decline significantly 
from current levels, further weakening profitability and eroding the company's 
liquidity. This could occur if industry fundamentals change and demand lessens 
because of lower automobile production rates or if supply increases because of 
higher production. Stillwater might not be able to recoup its cash costs if 
platinum prices fall to less than $1,000 per ounce within the next several 
quarters. In addition, we would consider a negative rating action if the 
company uses proceeds from the transaction to fund its capital expansion 
projects, rather than pay down debt.

An upgrade seems less likely in the near term given our view of the company's 
vulnerable business risk profile. In addition, we believe the company could 
increase debt significantly to fund its existing mine development projects.
