Forward-Looking Statements
This presentation contains forward-looking
statements with respect to market conditions,
operating costs, shipments, prices and
profit-based compensation payments. Some
factors, among others, that could affect 2007
market conditions, costs, shipments and prices
for both domestic operations and USSE include
global product demand, prices and mix global and
company steel production levels raw materials'
availability and prices plant operating
performance the timing and completion of
facility projects natural gas prices and usage
and availability changes in environmental, tax
and other laws the resumption of operation of
steel facilities sold under the bankruptcy laws
employee strikes power outages and U.S. and
global economic performance and political
developments. Domestic steel shipments and
prices could be affected by import levels and
actions taken by the U.S. Government and its
agencies. Political factors in Europe that may
affect USSEs results include, but are not
limited to, taxation, nationalization, inflation,
currency fluctuations, increased regulation,
export quotas, tariffs, and other protectionist
measures. The level of income from operations is
the primary factor affecting payments under the
USWA profit-based plans. In accordance with
safe harbor provisions of the Private
Securities Litigation Reform Act of 1995,
cautionary statements identifying important
factors, but not necessarily all factors, that
could cause actual results to differ materially
from those set forth in the forward-looking
statements have been included in the Form 10-K of
U. S. Steel for the year ended December 31, 2006,
and in subsequent filings for U. S. Steel.

Improving Industry Why invest in Steel?

• Steel is a good product, provides excellent
  value
• Major regions with increasing consumption rates
• Governments mostly out of industry (ex China)
• Metallics are tight, flatter cost curve
• Low Valuation

Bullish on North America
Optimistic outlook for North American integrated
producers

• Steady to moderate steel and economic growth
• Melt capacity relatively constrained
• High metallic costs
• High import transportation costs
• Relatively weak US Dollar

Capital Spending Building Value
U.S. Steel has spent less than global peers in
recent years Will likely incur higher capex
during next few years concentrated on
infrastructure, but will likely remain below the
global average.
