Braskem reported strong financial results for the first nine months of 2003, with net revenues increasing 36% and EBITDA growing 43% compared to the same period in 2002. Operating margins improved as average capacity utilization rates rose and sales volumes increased for most products. Braskem also reduced debt through refinancing and expects synergies from recent acquisitions to further boost profitability going forward. The company is well positioned to benefit from anticipated growth in the petrochemical sector and domestic Brazilian market starting in 2004.

16. The scenario looks promising for Braskem
The outlook is for higher thermoplastic resin prices on the international front,
with improved margins;
As confirmed by Chem Systems, the fly-up for the petrochemical sector is
expected for 2005;
On the international front, there is also the outlook for a gradual reduction in
oil and Naphtha prices in the next few years, providing the basis for a
consistent improvement in margins;
Domestically, the outlook is for GDP growth - as of 2004. This factor
associated with the high degree of elasticity for thermoplastic resins in Brazil,
indicate improved sales volumes to the domestic market.
Should the above outlook become a reality, Braskem can be expected to report
improved sales volumes, revenues and returns - as of 2004, onwards…
Braskem: Major growth potential in
sales volumes, revenues and margins.
