UC RUSAL announces its operating results for the third quarter ("3Q17”) 20171 Aluminium

Aluminium production2 in 3Q17 totaled 931 thousand tonnes (+1.1% QoQ), with Siberian smelters representing 94% of total aluminium output. The total production dynamics remained largely stable with capacity utilization rate standing at 95%;

In 3Q17, aluminium sales decreased (-3.4% QoQ) totaling 968 thousand tonnes. The QoQ decline in aluminium sales dynamics is largely explained by increase of goods in transit due to ports/vessels availability (volumes to be realized in the next period);

In 3Q17 sales of value added products (VAP3) stood at 479 thousand tonnes. The Company as per its strategy continued to grow the VAP’s share in total sales, which now stands at 50% in comparison with 49% in 2Q17 sales;

In 3Q17 the average aluminium realized price4 increased by 2.1 % QoQ to USD2,124/t due to positive dynamics in London Metal Exchange ("LME”) QP5 component (+2.9% QoQ to USD1,962/t). The average realized premium component declined (-7.0% QoQ to USD162/t) due to seasonal (summer time) market indicators decrease (WH Rotterdam, CIF MJP, Mid West).

Alumina

In 3Q17, total alumina production increased by 1.9% QoQ, totaling 1,965 thousand tonnes.

The continuation of capacities ramp up at Russia-based refineries post completion of upgrades earlier in 2017 coupled with growing production at Aughinish refinery on improved quality of purchased bauxites were largely behind the QoQ production increase for the Company overall, while Nikolaev refinery output was -3.5% down QoQ on the back of scheduled maintenance works.

Bauxite and nepheline ore

In 3Q17, Nepheline output was stable, marginally growing by 1.2% QoQ to 1,125 thousand tonnes, while consolidated bauxites output decreased by -11.3%, totaling 2,742 thousand tonnes. The Company covered alumina refineries consumption needs in relevant feedstock using the available inventory at its operations at Achinsk, Bogoslovsk, Urals and Windalco operations and additional purchased bauxite elsewhere.

Production volumes at Timan decreased by -5.5% QoQ to totaling 839 thousand tonnes and Kindia production volumes decreased by -11.0% QoQ to 717 thousand tonnes due to scheduled operational equipment care and maintenance works.

Abnormal weather conditions affected operational performance of Bauxite Company of Guyana production, which decreased to 161 thousand tonnes (-41.6% QoQ) and Windalco production which decreased to 476 thousand tonnes (-5.5% QoQ).

North Urals bauxite production declined by -11.0% QoQ to 548 thousand tonnes to match the needs of Urals alumina refinery where as part of working capital management, the feed from accumulated inventory was prioritized during the quarter.

Market overview6

The LME aluminium price fluctuated around USD1,900/t during March — July 2017, but then jumped to above USD2,100/t in August and reached USD2,164/t in September 2017, its highest level since December 2012. Price growth is attributed to market expectations of widespread capacity shutdowns during winter in China, the robust demand for aluminium during the period, coupled with significant production cost inflation.

The world economy witnessed broad based growth in 9M2017, with an increase in business activity, particularly in the developed economies. The main drivers for demand for aluminium were the growth of consumer spending particularly for cars and durable goods sales and also fixed asset investments.

In August-September, the JP Morgan Global Manufacturing PMI reached 53.2, a six-year high. Current multi-year high growth rates, particularly in the U.S. and Europe, continue to suggest underlying strong demand, which supports LME prices.

The Chinese economy continued to show strong growth through 9M2017. The official PMI reached 52.4 in September 2017, its highest since April 2012, and the Caixin Manufacturing PMI stood at a 51.0 level in September. GDP grew by 6.8% in 3Q17 Y-Y after 6.9% growth in 2Q17.

The reported inventories of aluminium in the World ex China declined further to 3.0 Mt at the end of September 2017, down 985 kt from the inventories level at the end of 2016. The days of consumption continued to decline at a steady rate during 9M2017 and fell to 36 days at the end of September 2017 as compared to 58 days at the end of 2016.

UC RUSAL estimates that global aluminium demand grew by 5.9% year-on-year in the 9 months of 2017 to 47.8 million tonnes as a result of strong demand in China, Europe, Asia ex-China, North America and India. Robust demand growth left the global aluminum market balance in a deficit of 0.8 million tonnes.

Based on CRU estimates, global aluminium demand ex-China rose by a strong 3.9% in 9M2017 year-on-year to 22.1 million tonnes while production (estimate based on IAI data plus CRU’s estimate for production of eight non-reporting countries) increased by 0.9% year-on-year to 20.3 million tonnes. This left the rest of the world aluminium market with approximately 1.8 million tonnes in deficit in 9M2017.

Demand for aluminum in China in 9M2017 grew by 7.7% to 25.7 million tonnes compared to the same period of last year.

The announcement by the Chinese regulator regarding winter capacity cuts, which is now underway in several provinces, was implemented to curb industrial pollution. As expected, winter smelting cuts will result in an annualized production loss of around 1 million tonnes and alumina around 3.3 million tonnes of alumina, according to UC Rusal estimates. Deeper losses may take place in carbon materials supply including anodes, coking coal etc., due to 100% closures in 26+2 cities during the winter season.

When considering the expected curtailments of the so-called "illegal capacities” on top of winter cuts, UC Rusal expects that during the winter season, the Chinese aluminium market balance may become very tight. As of the date of this announcement, according to SMM, around 4.2 million tonnes of illegal operating capacity have been closed.

As expected Chinese semis exports are expected to drop in 4Q17- 1H18 due to the tight domestic market and negative export arbitrage. Thus, China’s exports of aluminum semis fell 7.6% M-M (adjusted by a number of days in the months) to 358 kt in August 2017 and for second month in a row, fake extrusions exports dropped 31% YoY during 8M2017.

Net Debt

As part of commitment to continuous deleveraging, UC RUSAL has directed part of its strong 3Q17 cash flow to repayment of debt facilities and accumulated significant cash balance for further debt reduction.

According to management accounts, the management of the Group expects the net debt of the Group as at 30 September 2017 to be below US$7.7 billion, subject to update by the Company upon issue of the reviewed quarterly financial information as at and for the three and nine months ended 30 September 2017.
