In NAM, several PP capacity shutdowns have taken place since the last start up in US

• No new PP capacity additions in the region since 2008

• Shutdowns of 1.4 million tons of PP capacity between 1991-2015

• New Braskem PP plant will be the first one to startup in the region since 2008

Modelling Steps Suggestion

Source: Braskem Note (1): Based on External Consulting Firms. It considers catalyst, utilities, total fixed costs and local logistics.

Net Revenue(US$ MM)

COGS(US$ MM)

SG&A(US$ MM)

• Production (Kt) Production Capacity (kt) x Operating Rate (%);

• Sales Volume (Kt) Same as production, selling PP both in the domestic market and also exporting;

• Sales Price (US$/t) PP US International Reference (US$/t) and exports depends on the region;

• For modelling simplification, SG&A could be projected as a % of Net Revenue, which should be low, because the new facility leverages the existing infrastructure in La Porte, Texas (a range of 2-3% of Net Revenue).

• Feedstock Consumption (Kt) Production (Kt) x 1.01 (yield);

• Feedstock Cost (US$ MM) Feedstock Consumption (Kt) x Propylene US International Reference (US$/t);

• Cost ex-Feedstock (US$ MM) Polymerization Cost1 per unit (~US$200/t) x Production (Kt);

Modelling Delta's contribution to the company's results should be simple, given the characteristics of its business model
