the Company had earnings before items(1) of $103 million ($2.41 per share) for the fourth quarter of 2010
compared to earnings before items(1) of $183 million ($4.26 per share) for the third quarter of 2010 and
earnings before items(1) of $60 million ($1.39 per share) for the fourth quarter of 2009.

Fourth quarter 2010 items:

• Benefit from cellulosic biofuel producer income tax credit of $127
  million;
• Benefit from reversal of a valuation allowance on Canadian deferred
  income tax assets of $100 million;
• Costs for debt repurchase of $7 million ($4 million after tax); and
• Closure and restructuring costs of $1 million ($1 million after tax).

Third quarter 2010 items:

• Charge of $14 million ($9 million after tax) related to the impairment
  and write-down of property, plant and equipment;
• Closure and restructuring costs of $1 million ($1 million after tax);
  and

  and write-down of property, plant and equipment; and
• Loss on sale of property, plant and equipment of $5 million ($3 million
  after tax).

“Fourth quarter paper shipments were weaker partly due to seasonal
factors, but our average pricing held up well. We were able to post
best ever fourth quarter profit before items even though production
related issues resulted in higher than expected maintenance costs.
Higher pulp shipments, net of the impact of the sale of the Woodland
hardwood pulp facility, helped offset seasonal weakness. In addition,
we redeemed all of our 2011 notes, effectively completing our
systematic debt reduction program,” said John D. Williams, President and Chief Executive Officer. 

FISCAL YEAR 2010 HIGHLIGHTS

For fiscal year 2010, net earnings amounted to $605 million ($14.00 per
share) compared to net earnings of $310 million ($7.18 per share) for
fiscal year 2009. The Company had earnings before items(1) of $471 million ($10.90 per share) for fiscal 2010 compared to earnings
before items(1) of $46 million ($1.06 per share) for fiscal 2009. Sales amounted to
$5.9 billion for fiscal year 2010.

Commenting on the 2010 performance, Mr. Williams said, “We continued to aggressively execute on our “Perform, Grow, Break out”
strategic journey, thanks to excellent cost management and decisive
actions that realigned our asset portfolio and reduced our exposure to
challenging businesses. We have also made strategic investments in
growth markets that bode well for the future, notably in fluff pulp and
nanocrystalline cellulose, and built a flexible balance sheet that
provides us with the ability to seize opportunities. We are well
positioned for the year to come.”

SEGMENT REVIEW

Papers

Operating income before items(1) was $161 million in the fourth quarter of 2010 compared to operating
income before items(1) of $238 million in the third quarter of 2010. Depreciation and
amortization totaled $94 million in the fourth quarter of 2010. When
compared to the third quarter of 2010, paper and pulp shipments
decreased 5% and 9%, respectively. The shipments-to-production ratio
for paper was 97% in the fourth quarter of 2010, compared to 99% in the
third quarter of 2010. Paper inventories increased by 23,000 tons while
pulp inventories declined by 7,000 metric tons as at the end of
December versus end of September levels.

The decrease in operating income before items(1) in the fourth quarter of 2010 was the result of lower paper and pulp
shipments, lower average selling prices for pulp, unfavorable exchange
rate including hedging, higher usage and unit costs for energy and
chemicals, higher maintenance costs, and higher freight costs. These
factors were partially offset by lower wood fiber costs.

Paper Merchants

Operating loss before items(1) was $2 million in the fourth quarter of 2010 compared to operating
income before items(1) of nil in the third quarter of 2010. Depreciation and amortization was
$1 million in the fourth quarter of 2010. Deliveries decreased 11% when
compared to the third quarter of 2010. The decrease in operating income
in the fourth quarter of 2010 was primarily due to lower deliveries.

LIQUIDITY AND CAPITAL

Cash flow provided from operating activities amounted to $166 million
and capital expenditures amounted to $41 million, resulting in free
cash flow(1) of $125 million in the fourth quarter of 2010. Domtar’s net
debt-to-total capitalization ratio(1) stood at 9% at December 31, 2010 compared to 35% at December 31, 2009.

OUTLOOK

We expect North American paper demand to continue declining long-term,
partially offset by a gradual return of employment in the U.S. closer
to pre-recession levels. Our Papers segment is benefiting from a more
favorable pulp product mix that should result in reduced pricing
volatility. Rising commodity pricing should also put pressure on some
of our input costs in 2011.

While the economy appears to be stabilizing, employment remains slow to
recover.  Though we are entering 2011 with a strong position, we will
continue to manage our business conservatively, looking to grow
profitably and to create shareholder value.
