ISS Recommends Sweeping Board Change at Stillwater Mining Company

ISS called the "failure" of the incumbent Board "bewildering." Accordingly, ISS concluded that "shareholders should vote on the GREEN card."

"We are pleased that ISS recognizes the importance of change at Stillwater," said Gregory P. Taxin, Managing Director of Clinton. "A new, independent Board can help to protect and create stockholder value by bringing objective oversight to the Company."

ISS' research report also says:

• "The most compelling concern for many shareholders ... has been the acquisitions of two exploration-stage mining companies, Marathon and Peregrine, at eye-popping prices, to fuel diversification strategy investors did not want, and the company does not appear able to fund."
• "Discussions with longer-term shareholders reinforce the dissidents' assertions that the principal flaw in the board's diversification strategy was diversification itself. As the board's current investor presentations now suggest, the company was the only pure-play US PGM producer, and the largest in North America. Investors might have bought into Stillwater shares to diversify their own portfolios, but they generally preferred to do such diversification on their own, and placed some premium on the ability to allocate capital cleanly by buying into a pure-play PGM producer in a stable regulatory and labor market."
• "Over the CEO's full tenure, as the dissidents have pointed out, the reality is ... sobering. Total operating expenses ... nearly tripled, and cash cost per ounce had nearly doubled, even as ounces of production declined modestly."
• "Compensation to the CEO ... has nearly doubled since 2009, and director compensation is up 60% since 2010."

With respect to the particular individuals the Clinton Group has nominated, ISS said:

• Dr. Engles, the founding CEO of Stillwater, was the "architect of the initial [Stillwater] strategy and guided the [then] newly-public company to strong shareholders returns in the years after its IPO," noting that his nomination is "heartening on both the operating and strategic fronts."
• Ms. Merrin "has extensive board experience, across several industries, which suggests she could add a welcome sense of shareholder accountability to this board."
• Mr. McMullen has "expertise [that] appears particularly well-suited to the needs of the reconstituted board."
• Governor Schweitzer "would appear to offer significant strengths to this board."

The Stillwater annual meeting is scheduled to be held on May 2, 2013. Clinton urges its fellow stockholders to use the GREEN proxy card when voting at this year's annual meeting and to vote for the Clinton nominees.
