Reconciliation for Value-Added Sales A-18 $ in millions Value-added sales is a non-GAAP measure that removes the impact of pass-through metal costs and allows for analysis without the distortion of the movement or volatility in metal prices. Internally, we manage our business on this basis, and a reconciliation of net sales to value-added sales is included herein. 2012 2013 2014 2015 Q3 2016 TTM Net Sales Performance Alloys and Composites 424.4$ 422.9$ 433.3$ 394.8$ 382.3$ Advanced Materials 694.8 592.0 547.3 482.3 416.3 Precision Coatings 153.0 152.3 147.7 148.4 150.4 Other 0.9 (0.3) (1.3) (0.2) - Total 1,273.1$ 1,166.9$ 1,126.9$ 1,025.3$ 949.0$ Less: pass-through metal costs Performance Alloys and Composites 87.4$ 83.0$ 74.8$ 59.6$ 55.0$ Advanced Materials 522.7 423.4 366.2 299.5 241.4 Precision Coatings 46.7 48.0 45.3 46.7 48.5 Other 0.7 3.3 3.5 2.2 5.8 Total 657.5$ 557.8$ 489.8$ 408.0$ 350.7$ Value-added sales Performance Alloys and Composites 337.0$ 339.9$ 358.5$ 335.1$ 327.2$ Advanced Materials 172.1 168.6 181.0 182.8 174.9 Precision Coatings 106.4 104.2 102.4 101.8 101.9 Other 0.1 (3.6) (4.9) (2.4) (5.8) Total 615.6$ 609.1$ 637.1$ 617.2$ 598.2$

Reconciliation for Adjusted EPS A-19 As detailed in the above reconciliation, we have adjusted the results for certain special items such as insurance and other litigation claims, legacy environmental costs, merger and acquisition costs, cost reduction actions, and certain income tax items from the applicable GAAP measure. Internally, management reviews the results of operations without the impact of these costs in order to assess the profitability from ongoing activities. We are providing this information because we believe it will assist investors in analyzing our financial results and, when viewed in conjunction with the GAAP results, provide a more comprehensive understanding of the factors and trends affecting our operations.

Reconciliation for Debt-to-Capitalization A-20 Debt-to-capitalization is our total debt divided by net debt plus shareholders’ equity. Net debt (cash) is a non-GAAP measure calculated by subtracting cash & cash equivalents from our total outstanding debt. We are providing this information because we believe it is more indicative of our overall financial position. It is also a measure our management uses to assess financing and other decisions. $ in millions 2014 2013 Total outstanding debt 13.3$ 23.9$ 64.3$ Less: Cash & cash equivalents 24.2 13.1 22.8 Net (cash) debt (10.9)$ 10.8$ 41.5$ Total Shareholders' Equity 483.0$ 459.0$ 464.4$ Net Debt-to-Capitalization 3% 5% 13% 2015

Reconciliation for EV / Adjusted EBITDA A-21 Amounts in millions, except share price EV/Adjusted EBITDA is our enterprise value divided by adjusted EBITDA. Adjusted EBITDA is calculated by adding depreciation, depletion & amortization and certain special items such as insurance and other litigation claims, legacy environmental costs, merger and acquisition costs, cost reduction actions, and certain income tax items to our operating profit. Internally, management reviews the results of operations without the impact of these costs in order to assess the profitability from ongoing activities.
