METHANEX REPORTS FOURTH QUARTER RESULTS AND STRONGER EARNINGS IN 2011

JANUARY 25, 2012

For the fourth quarter of 2011, Methanex reported Adjusted EBITDA’ of $133 million and net income attributable to
Methanex shareholders of $64 million ($0.68 per share on a diluted basis). This compares with Adjusted EBITDA! of $111
million and net income attributable to Methanex shareholders of $62 million ($0.59 per share on a diluted basis) for the
third quarter of 2011. For the year ended December 31, 2011, Methanex reported Adjusted EBITDA! of $427 million and
net income attributable to Methanex shareholders of 201 million ($2.06 per share on a diluted basis”). This compares with
Adjusted EBITDA!’ of $291 million and net income attributable to Methanex shareholders of $96 million ($1.03 per share
on a diluted basis) for the year ended December 31, 2010.

Bruce Aitken, President and CEO of Methanex commented, “Methanol demand and pricing has been relatively stable and
we reported another good quarter of earnings. For 2011, we are also pleased to have reported record sales volumes and
significantly higher earnings, as a result of a healthy methanol pricing environment and higher production due to the start
up of the Egypt and Medicine Hat plants over the past year.”

Mr. Aitken added, “We have significantly more upside potential to our production and earnings. We recently announced
the planned restart of a second plant in New Zealand in mid-2012 and we are aggressively pursuing other initiatives to
increase the utilization of our Chile assets, including a project to relocate one of the idle plants to the U.S. Gulf Coast for
start-up in the second half of 2014. The outlook for the industry also looks very attractive, as demand growth is expected to
significantly exceed new capacity additions over the next few years.”

Mr. Aitken concluded, “With over US$300 million of cash on hand, an undrawn credit facility, a robust balance sheet, and
strong cash flow generation, we are well positioned to invest in strategic opportunities to grow the Company, and continue
to deliver on our commitment to return excess cash to shareholders.”

FORWARD-LOOKING INFORMATION WARNING

This Fourth Quarter 2011 press release contains forward-looking statements with respect to us and the chemical industry.
Refer to Forward-Looking Information Warning in the attached Fourth Quarter 2011 Management’s Discussion and Analysis

for more information.

7 Adjusted EBITDA is a non-IFRS measure which does not have any standardized meaning prescribed by IFRS. Adjusted EBITDA represents the amount that ¡is
attributable to Methanex shareholders and is calculated by deducting the amount of Adjusted EBITDA associated with the 40% non-controlling interest in the
methanol facility in Egypt. Commencing with this fourth quarter interim report, we have modified our definition of Adjusted EBITDA to exclude the mark-to-market
impact of items which impact the comparability of our earnings from one period to another, which currently include only the mark-to-market impact of share-based
compensation as a result of changes in our share price. Refer to Financial Results on page 4 for a discussion of this change and Additional Information –
Supplemental Non-IFRS Measures for a reconciliation to the most comparable IFRS measure.

For the year ended December 31, 2011, diluted net income per common share ¡is $0.10 lower than basic net income per common share. The large difference
between diluted and basic net income per common share is due to the basis for the calculation of diluted net income per common share differing from the
accounting treatment for certain types of share-based compensation. See note 8 of the Company’s condensed consolidated interim financial statements for the
calculation of diluted net income per common share.

The production capacity of our production facilities may be higher than original nameplate capacity as, over time, these figures have been adjusted to reflect
ongoing operating efficiencies at these facilities.

The production capacity of New Zealand represents only our 0.85 million tonne per year Motunui facility that we restarted in late 2008. We recently announced
our intention to restart a second Motunui facility in mid-2012 (refer to the New Zealand section on page 3 for more information).

Chile

For the year ended December 31, 2011, we produced 554,000 tonnes compared with 935,000 tonnes in 2010. We
continue to operate our methanol facilities in Chile significantly below site capacity. This is primarily due to curtailments of
natural gas supply from Argentina – refer to the Management’s Discussion and Analysis included in our 2010 Annual
Report for more information.

During the fourth quarter of 2011, we produced 113,000 tonnes in Chile operating one plant at approximately 40% of
capacity. This compares with 116,000 tonnes produced during the third quarter of 2011. Empresa Nacional del Petroleo
(ENAP), the state-owned energy supplier, utilizes incremental natural gas during the winter season in southern Chile when
residential demand is at its peak. We are working closely with ENAP to manage through the seasonality of gas demand
with the objective of maintaining our operations throughout the winter season in 2012.

Our primary goal is to progressively increase production at our Chile site with natural gas from suppliers in Chile. We are
pursuing investment opportunities with ENAP, GeoPark Chile Limited (GeoPark) and others to help accelerate natural gas
exploration and development in southern Chile. We are working with ENAP to develop natural gas in the Dorado Riquelme
block. Under the arrangement, we fund a 50% participation in the block and, as at December 31, 2011, we had
contributed approximately $106 million. Over the past few years, we have also provided GeoPark with $57 million (of
which approximately $40 million had been repaid at December 31, 2011) to support and accelerate GeoPark’s natural gas
exploration and development activities. GeoPark has agreed to supply us with all natural gas sourced from the Fell block
under a ten-year exclusive supply arrangement that commenced in 2008. During the fourth quarter of 2011, approximately
75% of production at our Chilean facilities was produced with natural gas supplied from the Fell and Dorado Riquelme
blocks.

Other investment activities are also supporting the acceleration of natural gas exploration and development in areas of
southern Chile. Over the past few years, the government of Chile has completed international bidding rounds to assign oil

METHANEX CORPORATION 2011 FOURTH QUARTER REPORT PAGE 2
MANAGEMENT’S DISCUSSION AND ANALYSIS

and natural gas exploration areas that lie close to our production facilities and announced the participation of several
international oil and gas companies. For two of the exploration blocks, we are participating in a consortium with other
international oil and gas companies with GeoPark as the operator. We have approximately a 15% participation in the
consortium and at December 31, 2011, we had contributed $9 million for our share of the exploration costs.

While significant investments have been made in the last few years for natural gas exploration and development in southern
Chile, the timelines for significant increases in gas production are much longer than we had originally anticipated and
existing gas fields are experiencing declines. As a result, the short-term outlook for gas supply in Chile continues to be
challenging and we are also examining the viability of other projects to increase the utilization of our Chilean assets. We
are planning to relocate one of the idle Chile methanol plants with a capacity of approximately 1.0 million tonnes to the
Gulf Coast area of the United States. We recently announced that we have secured land in Geismar, Louisiana and are
progressing site-specific engineering works. We expect to make a final investment decision in Q3 2012 and the plant to be
operational in the second half of 2014. We are also continuing to examine the viability of utilizing coal gasification as an
alternative feedstock in Chile.

The future operating rate of our Chile site is primarily dependent on demand for natural gas for residential purposes, which
is higher in the southern hemisphere winter, production rates from existing natural gas fields, and the level of natural gas
deliveries from future exploration and development activities in southern Chile. We cannot provide assurance regarding the
production rates from existing natural gas fields or that we, ENAP, GeoPark or others will be successful in the exploration
and development of natural gas or that we will obtain any additional natural gas from suppliers in Chile on commercially
acceptable terms. As a result, we cannot provide assurance in the level of natural gas supply or that we will be able to
source sufficient natural gas to operate any capacity in Chile or that we will have sufficient future cash flows from Chile to
support the carrying value of our Chilean assets and that this will not have an adverse impact on our results of operations
and financial condition.

Trinidad

Our equity ownership of methanol facilities in Trinidad represents over 2.0 million tonnes of cost-competitive annual
capacity. During the fourth quarter of 2011 we produced 375,000 tonnes compared with an operating capacity of 512,500
tonnes. As a result of an equipment failure in July 2011, our Atlas facility operated at approximately 70% of capacity
throughout the fourth quarter. The plant was shut down for a maintenance outage to complete the repair in January 2012
which is expected to last approximately 40 days. In addition, production at our Titan facility was lower than capacity,
primarily due to outages for minor repairs and lower gas deliveries. We continue to experience some natural gas
curtailments to our Titan facility due to upstream outages. We are engaged with key stakeholders to find a solution to this
issue, but in the meantime expect to continue to experience some gas curtailments to our Trinidad site.

New Zealand

During the fourth quarter of 2011, we produced 211,000 tonnes compared with 209,000 tonnes during the third quarter of
2011. We are currently operating one 850,000 tonne per year plant at our Motunui facility in New Zealand.

We recently announced our intention to restart a second Motunui facility in mid-2012. The restart of this facility will add
up to 650,000 tonnes of incremental capacity per annum to our New Zealand operations. In support of the restart,
Methanex has entered into a ten-year gas supply agreement which is expected to supply up to half of the 1.5 million tonnes
of annual capacity at the Motunui site.

We also have an additional 530,000 tonne per year plant at the nearby Waitara Valley site which remains idle. This facility
provides additional potential to increase New Zealand production depending on the methanol supply and demand
dynamics and the availability of economically priced natural gas.

METHANEX CORPORATION 2011 FOURTH QUARTER REPORT PAGE 3
MANAGEMENT’S DISCUSSION AND ANALYSIS

Egypt

During the fourth quarter of 2011, the Egypt methanol facility (60% interest) produced 132,000 tonnes compared with
191,000 tomnes during the third quarter of 2011. We have a 60% interest in the facility and have marketing rights for 100%
of the production.

In November 2011, civil unrest affected various industries near the plant in Damietta, Egypt. For the safety and security of
our employees, we took the decision to temporarily curtail operations of the methanol plant. We restarted the facility in
early December and since that time, the methanol facility in Egypt has operated well.

Medicine Hat

Our 470,000 tonne per year facility in Medicine hat, Alberta was restarted in late April 2011 and has continued to operate
well since that time. During the fourth quarter of 2011, we produced 130,000 tonnes compared with 125,000 tonnes
during the third quarter of 2011. We have a program in place to purchase natural gas on the Alberta gas market and we
believe that the long term natural gas dynamics in North America will support the long term operation of this facility.

FINANCIAL RESULTS

For the fourth quarter of 2011 we recorded Adjusted EBITDA of $133 million and net income attributable to Methanex
Corporation shareholders of $64 million ($0.69 basic net income per common share and $0.68 per share on a diluted
basis). This compares with Adjusted EBITDA of $111 million and net income attributable to Methanex Corporation
shareholders of $62 million ($0.67 basic net income per common share and $0.59 per share on a diluted basis) for the third
quarter of 2011 and Adjusted EBITDA of $88 million and net income attributable to Methanex Corporation shareholders of
$26 million ($0.28 basic net income per common share and $0.27 per share on a diluted basis) for the fourth quarter of
2010.

For the year ended December 31, 2011, we recorded Adjusted EBITDA of $427 million and net income attributable to
Methanex Corporation shareholders of $201 million ($2.16 basic net income per common share and $2.06 per share on a
diluted basis). This compares with Adjusted EBITDA of $291 million and net income attributable to Methanex Corporation
shareholders of $96 million ($1.04 basic net income per common share and $1.03 per share on a diluted basis) during the
same period in 2010.

MANAGEMENT’S DISCUSSION AND ANALYSIS

Adjusted EBITDA (attributable to Methanex shareholders)

Our operations consist of a single operating segment – the production and sale of methanol. We review our results of
operations by analyzing changes in the components of our adjusted earnings before interest, taxes, and depreciation and
amortization (“Adjusted EBITDA”).

We own 60% of the 1.26 million tonne per year Egypt methanol facility and we account for this investment using
consolidation accounting, which results in 100% of the revenues and expenses being included in our financial statements
with the other investors” interest in the methanol facility being presented as “non-controlling interests.” For purposes of
reviewing our operations, we analyze Adjusted EBITDA by excluding the amounts associated with the other investors” 40%
non-controlling interest.

Commencing with this fourth quarter interim report, we have modified our definition of Adjusted EBITDA to exclude the
mark-to-market impact of items which impact the comparability of our results from one period to another, which currently
include only the mark-to-market impact of share-based compensation as a result of changes in our share price. We grant
share-based awards as an element of compensation and, as more fully discussed on page 7, certain of these awards are
marked to market each period with the changes in fair value recognized in earnings for the proportion of the service that
has been rendered at the reporting date. We believe excluding the mark-to-market impact of share-based compensation as
a result of changes in our share price will provide readers with a better measure of the Company’s underlying ability to
generate cash from operations and improve the comparability of our results from one period to another. A reconciliation of
the change in the definition of Adjusted EBITDA is as follows:

Three Months Ended Years Ended
Dec 31 Sep 30 Dec 31 Dec 31 Dec 31
($ millions) 2011 2011 2010 2011 2010

For a further discussion of the definitions used in our Adjusted EBITDA analysis, refer to How We Analyze Our Business on
page 18. Also, refer to the Additional Information – Supplemental Non-IFRS Measures section on page 13 for a

1 Methanex average non-discounted posted price represents the average of our non-discounted posted prices in North America, Europe and Asia Pacific weighted by
sales volume. Current and historical pricing information is available at www.methanex.com.

During the fourth quarter of 2011, methanol demand remained stable, despite the ongoing concern around the global
economy (refer to Supply/Demand Fundamentals section on page 10 for more information). Overall industry supply and
demand conditions remained balanced and as a result, the pricing environment remained relatively stable. Our average
non-discounted posted price for the fourth quarter of 2011 was $456 per tonne compared with $445 per tonne for the third
quarter of 2011 and $407 per tonne for the fourth quarter of 2010. Our average realized price for the fourth quarter of 2011
was $388 per tonne compared with $377 per tonne for the third quarter of 2011 and $348 per tonne for the fourth quarter
of 2010. The change in our average realized price for the fourth quarter of 2011 increased Adjusted EBITDA by $18
million compared with the third quarter of 2011 and increased Adjusted EBITDA by $70 million compared with the fourth
quarter of 2010. Our average realized price for the year ended December 31, 2011 was $374 per tonne compared with
$306 per tonne for the same period in 2010 and this increased Adjusted EBITDA by $454 million.

Sales volume

Total methanol sales volumes excluding commission sales volumes were higher in 2011 than 2010 and this increased
Adjusted EBITDA for all periods presented. We increased our sales volumes in 2011 compared with 2010 primarily as a
result of increased supply from the new Egypt and Medicine Hat methano!l facilities.

Total cash costs

The primary driver of changes in our total cash costs are changes in the cost of methanol we produce at our facilities and
changes in the cost of methanol we purchase from others. All of our production facilities except Medicine Hat are
underpinned by natural gas purchase agreements with pricing terms that include base and variable price components. The
variable component is adjusted in relation to changes in methanol prices above pre-determined prices at the time of
production. We supplement our production with methanol produced by others through methanol offtake contracts and
purchases on the spot market to meet customer needs and support our marketing efforts within the major global markets.

We have adopted the first-in, first-out method of accounting for inventories and it generally takes between 30 and 60 days
to sell the methanol we produce or purchase. Accordingly, the changes in Adjusted EBITDA as a result of changes in
Methanex-produced and purchased methanol costs will depend on changes in methanol pricing and the timing of inventory
flows.

The impact on Adjusted EBITDA from changes in our cash costs are explained below:

METHANEX CORPORATION 2011 FOURTH QUARTER REPORT PAGE 6

MANAGEMENT’S DISCUSSION AND ANALYSIS

Methanex-produced methanol costs

We purchase natural gas for the Chile, Trinidad, Egypt and New Zealand methanol facilities under natural gas purchase
agreements where the terms include a base price and a variable price component linked to the price of methanol. For all
periods presented, changes in Methanex-produced methanol costs were primarily due to the impact of changes in methanol
prices on our natural gas costs and the timing of inventory flows.

Insurance Recovery

We experienced an equipment failure at our Atlas facility in July 2011 and have operated this facility at approximately 70%
of capacity since its restart. Our operations are covered by business interruption insurance and we have recorded the
estimated insurance proceeds net of deductibles related to 2011 as a result of this event.

Proportion of produced methanol sales

The cost of purchased methanol ¡is generally higher than the cost of produced methanol. Accordingly, an increase in the
proportion of produced methanol sales results in a decrease in our overall cost structure for a given period. For the fourth
quarter of 2011 compared with the third quarter of 2011, higher sales of produced methanol increased Adjusted EBITDA by
$4 million. For the fourth quarter of 2011 compared with the fourth quarter of 2010, higher sales of produced methanol,
primarily due to the impact of sales volumes from the Egypt and Medicine Hat facilities, increased Adjusted EBITDA by $26
million.

For the year ended December 31, 2011 compared with the same period in 2010, higher sales of produced methanol
increased Adjusted EBITDA by $24 million. The impact of higher sales volumes from our Egypt and Medicine Hat facilities
in 2011 was partially offset by lower sales of methanol produced at our Chile and Titan facilities.

Purchased methanol costs
Purchased methanol costs were higher for all periods presented primarily as a result of higher methanol pricing.
Logistics costs

For the year ended December 31, 2011 compared with same period in 2010, logistics costs were higher by $16 million
due primarily to higher bunker fuel costs and fewer backhaul opportunities to recover our ocean vessel costs.

Other, net

For all periods presented, other costs were higher primarily as a portion of fixed manufacturing costs were charged directly
to earnings rather than to inventory due to lower production at our facilities in Chile, Trinidad and Egypt as well as the
impact of a weaker US dollar on the cost structure of our operations.

Mark-to-Market Impact of Share-based Compensation

We grant share-based awards as an element of compensation. Share-based compensation expense (recovery) includes an
amount related to the grant-date fair value and a mark-to-market impact as a result of subsequent changes in the Company/’s
share price. The grant-date fair value amount is included in Adjusted EBITDA and analyzed above. The mark-to-market
impact of share-based compensation as a result of changes in the share price is excluded from Adjusted EBITDA and
analyzed separately below.

METHANEX CORPORATION 2011 FOURTH QUARTER REPORT PAGE 7
MANAGEMENT’S DISCUSSION AND ANALYSIS

For stock options, the cost is measured based on an estimate of the fair value at the date of grant using the Black-Scholes
option pricing model and this grant-date fair value is recognized as compensation expense over the related service period
with no subsequent re-measurement in fair value. Accordingly, share-based compensation expense associated with stock
options will not vary significantly from period to period.

Commencing in 2010, we granted share appreciation rights (SARs) and tandem share appreciation rights (TSARs) to replace
grants of stock options with the objective to reduce dilution to shareholders. SARs and TSARs are units that grant the holder
the right to receive a cash payment upon exercise for the difference between the market price of the Companys common
shares and the exercise price, which is determined at the date of grant. The fair value of SARs and TSARs are re-measured
each quarter using the Black-Scholes option pricing model, which considers the market value of the Company’s common
shares on the last trading day of the quarter.

Deferred, restricted and performance share units are grants of notional common shares that are redeemable for cash upon
vesting based on the market value of the Company’s common shares and are non-dilutive to shareholders. Performance
share units have an additional feature where the ultimate number of units that vest will be determined by the Company/’s
total shareholder return in relation to a predetermined target over the period to vesting. The number of units that will
ultimately vest will be in the range of 50% to 120% of the original grant. For deferred, restricted and performance share
units, the fair value is initially measured at the grant date and subsequently re-measured based on the market value of the
Company’s common shares on the last trading day of each quarter.

For all the share-based awards, the grant-date fair value is recognized in earnings and Adjusted EBITDA over the related
service period for the proportion of the service that has been rendered at each reporting date. Any mark-to-market impact as
a result of subsequent changes in the share price are also recognized in earnings over the related service period for the
proportion of the service that has been rendered at each reporting date but are excluded from Adjusted EBITDA.

Depreciation and Amortization

Depreciation and amortization was $44 million for the fourth and third quarter of 2011 and $32 million for the fourth
quarter of 2010. Depreciation and amortization was $157 million for the year ended December 31, 2011 compared with
$137 million in the same period in 2010. The increase in depreciation and amortization in 2011 compared with 2010 is
primarily a result of the commencement of depreciation associated with the methanol facilities in Egypt (100% basis) and
Medicine Hat and due to a portion of depreciation being charged directly to earnings rather than to inventory due to lower
production from our Titan and Chile facilities.

Finance income and other expenses for the fourth quarter of 2011 was an expense of $3 million compared with an expense
of $2 million for the third quarter of 2011 and income of $3 million for the fourth quarter of 2010. Finance income and
other expenses for the year ended December 31, 2011 was $2 million income compared with $2 million income for the
year ended December 31, 2010. The change in finance income and other expenses for all periods presented was primarily
due to the impact of changes in foreign exchange rates.

Income Taxes

The effective tax rate for the fourth quarter of 2011 was approximately 14% compared with approximately 20% for the
third quarter of 2011. The effective tax rate for the year ended December 31, 2011 was 20% compared with 32% for the
year ended December 31, 2010, excluding the impact of a gain on the sale of land and terminal assets in Kitimat, Canada
recorded in 2010.

We earn the majority of our pre-tax earnings in Trinidad, Egypt, Chile, Canada and New Zealand. In Trinidad and Chile,
the statutory tax rate is 35% and in Egypt, the statutory tax rate is 25%. Our Atlas facility in Trinidad has partial relief from
corporation income tax until 2014. During the three months and year ended December 31, 2011, we earned a higher
proportion of our consolidated income from methanol produced in Canada and New Zealand and a lower proportion of
our consolidated income from methanol produced in Chile, and this contributed to a lower effective tax rate compared with
the same periods in 2010. We have significant loss carryforwards in Canada and New Zealand which have not been
recognized for accounting purposes.

In Chile the tax rate consists of a first tier tax that is payable when income is earned and a second tier tax that is due when
earnings are distributed from Chile. The second tier tax is initially recorded as deferred income tax expense and is
subsequently reclassified to current income tax expense when earnings are distributed.

MANAGEMENT’S DISCUSSION AND ANALYSIS

SUPPLY/DEMAND FUNDAMENTALS

We estimate that methanol demand grew at approximately 6% in 2011 and is currently approximately 49 million tonnes on
an annualized basis. Increases in demand have been driven by both traditional and energy derivatives in Asia (particularly
in China). Entering the first quarter of 2012, despite continued concerns around the global economic outlook, we have not
seen any significant impact on global methanol demand.

Traditional derivatives account for about two-thirds of global
methanol demand and are correlated to industrial production.

Energy derivatives account for about one third of global methanol Methanex Non-Discounted Regional Posted Prices *

that country. Many provinces in China have implemented fuel
blending standards, and an M85 (or 85% methanol) national

standard took effect December 1, 2009. We believe demand potential into energy derivatives will be stronger in a high
energy price environment.

During the fourth quarter of 2011, as a result of steady demand and planned and unplanned industry outages, market
conditions and the pricing environment were relatively stable. Our average non-discounted price for January 2012 is
approximately $434 per tonne and we recently announced our North America non-discounted price for February at $446
per tonne, which is unchanged from January.

Over the next few years, there is a modest level of new capacity expected to come on-stream relative to demand growth
expectations. We recently announced that we are planning to restart an idle plant in New Zealand in mid-2012 that will
add 0.65 million tonnes of capacity and relocate a plant from Chile with an approximate capacity of 1.0 million tonnes to
Geismar, Louisiana which we expect to be operational in the second half of 2014. There is also a 0.85 million tonne plant
expected to restart in Beaumont, Texas in 2012, a 0.8 million tonne plant expected to restart in Channelview, Texas in
2013, and a 0.7 million tonne plant expected to start up in Azerbaijan in 2014. We expect that production from new
capacity in China will be consumed in that country and that higher cost production capacity in China will need to operate
in order to satisfy demand growth.

LIQUIDITY AND CAPITAL RESOURCES

Consolidated cash flows from operating activities in the fourth quarter of 2011 were $158 million compared with $119
million for the third quarter of 2011 and $13 million for the fourth quarter of 2010. The change in consolidated cash flows
from operating activities in the fourth quarter of 2011 compared with the third quarter of 2011 and the fourth quarter of
2010 is primarily a result of changes in Adjusted EBITDA and changes in non-cash working capital.

Adjusted cash flows from operating activities, which excludes the amounts associated with the 40% non-controlling
interests in the methanol facility in Egypt and changes in non-cash working capital, were $122 million in the fourth quarter
of 2011 compared with $104 million for the third quarter of 2011 and $94 million for the fourth quarter of 2010. The
change in Adjusted cash flows from operating activities in the fourth quarter of 2011 compared with the third quarter of
2011 and the fourth quarter of 2010 is primarily a result of changes in Adjusted EBITDA. Refer to the Additional
Information – Supplemental Non-IFRS Measures section on page 13 for a reconciliation of Adjusted cash flows from
operating activities to the most comparable IFRS measure.

During the fourth quarter of 2011, we paid a quarterly dividend of $0.17 per share, or $16 million.

METHANEX CORPORATION 2011 FOURTH QUARTER REPORT PAGE 10
MANAGEMENT’S DISCUSSION AND ANALYSIS

The Egypt limited recourse debt facilities required that certain conditions associated with plant construction and
commissioning be met by September 30, 2011 (“project completion”). Project completion was achieved during the third
quarter of 2011. In connection with achieving project completion, we agreed to a covenant to complete by March 31,
2012 certain land title registrations and related mortgages which require action by Egyptian government entities and which
we do not expect to complete by March 31, 2012 and will seek a waiver from the lenders. We do not believe that the
finalization of these items is material. We cannot assure you that we will be able to obtain a waiver from the lenders. Refer
to note 5 of the Company’s condensed consolidated interim financial statements for further information.

At December 31, 2011, management believes the Company was in compliance with all of the covenants and default
provisions related to its long-term debt obligations.

We have agreements in place to participate in or support natural gas exploration and development in southern Chile and
during the fourth quarter of 2011, we spent $8 million to support these initiatives.

We operate in a highly competitive commodity industry and believe it is appropriate to maintain a conservative balance
sheet and to maintain financial flexibility. Our cash balance at December 31, 2011 was $351 million including $37 million
related to the non-controlling interest in Egypt. We have a strong balance sheet and an undrawn $200 million credit facility
provided by highly rated financial institutions that was extended early in the third quarter of 2011 to mid-2015. We intend
to refinance the $200 million notes due August 2012. We invest our cash only in highly rated instruments that have
maturities of three months or less to ensure preservation of capital and appropriate liquidity. Our planned capital
maintenance expenditure program directed towards major maintenance, turnarounds and catalyst changes for existing
operations, is currently estimated to total approximately $60 million to the end of 2012. We also recently announced our
intention to restart a second facility in New Zealand with an estimated future capital cost of $60 million.

We believe we are well positioned to meet our financial commitments and continue to invest to grow the Company.

SHORT-TERM OUTLOOK

Despite continued concerns regarding the health of the global economy, we have not seen a significant change in demand
for methanol and pricing remains relatively stable entering the first quarter of 2012.

We increased our production in 2011 with the new 1.26 million tonne per year methanol facility in Egypt and our 470,000
tonne per year plant in Medicine Hat, Alberta. These facilities are operating well and have increased our earnings
capability. Our Atlas facility is currently undergoing a maintenance outage after which we expect it to return to operating at
full capacity . We also recently announced our intention to restart a second plant in New Zealand in mid-2012.

The methanol price will ultimately depend on the strength of the global economy, industry operating rates, global energy
prices, new supply additions, the rate of industry restructuring and the strength of global demand. We believe that our
financial position and financial flexibility, outstanding global supply network and competitive-cost position will provide a
sound basis for Methanex to continue to be the leader in the methanol industry and to invest to grow the Company.

CONTROLS AND PROCEDURES

For the three months ended December 31, 2011, no changes were made in our internal control over financial reporting that
have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

INTERNATIONAL FINANCIAL REPORTING STANDARDS (IFRS)

Transition from Canadian generally accepted accounting principles (Canadian GAAP) to IFRS

The first quarter of 2011 ended March 31, 2011 with comparative financial results for 2010 was our first interim period
reported under IFRS. All comparative figures in this fourth quarter interim report have been restated to be in accordance
with IFRS, unless specifically noted otherwise.

Our financial statements were prepared in accordance with Canadian GAAP until December 31, 2010. While IFRS uses a
conceptual framework similar to Canadian GAAP, there are significant differences in recognition, measurement and
disclosures. In our MDgA in the 2010 Annual Report, we disclosed the significant impacts on transition to IFRS. The
transition to IFRS had a cumulative impact on January 1, 2010 of $25 million to the shareholders” equity, excluding the
presentation reclassification of the non-controlling interest. The disclosure in our MDéA in the 2010 Annual Report is
consistent with the impacts disclosed in the condensed consolidated interim financial statements. For a description of the
significant accounting policies the Company has adopted under IFRS, including the estimates and judgments we consider
most significant in applying those accounting policies, please refer to note 2 of the condensed consolidated interim
financial statements included in the interim report for the three months ended March 31, 2011.

The adoption of IFRS resulted in some changes to the consolidated balance sheets and income statements of the Company
previously reported under Canadian GAAP. To help users of the financial statements better understand the impact of the
adoption of IFRS on the Company, we have provided reconciliations from Canadian GAAP to IFRS for total assets,
liabilities, and equity, as well as net income and comprehensive income for the comparative reporting periods. Please refer
to note 13 of the condensed consolidated interim financial statements for the reconciliations between IFRS and Canadian
GAAP for the period ended December 31, 2010 and refer to note 18 of the condensed consolidated interim financial
statements for the period ended March 31, 2011 for the reconciliations between IFRS and Canadian GAAP at the date of
transition, January 1, 2010 and for the year ended December 31, 2010.

IFRS 1 First-time Adoption of International Financial Reporting Standards

Adoption of IFRS requires the application of IFRS 1, First-time Adoption of International Financial Reporting Standards,
which provides guidance for an entity’s initial adoption of IFRS. IFRS 1 gives entities adopting IFRS for the first time a
number of optional exemptions and mandatory exceptions, in certain areas, to the general requirement for full retrospective
application of IFRS. In our MDáA in the 2010 Annual Report, we disclosed the optional exemptions available under IFRS
1 that we elected on transition to IFRS. The elections as previously disclosed are consistent with the elections as disclosed
in the condensed consolidated interim financial statements. Please refer to note 13 of the condensed consolidated interim
financial statements for the period ended March 31, 2011 for a detailed description of the IFRS 1 exemptions we elected to
apply.

IFRS Conversion

Our plan to convert our consolidated financial statements to IFRS at the change over date of January 1, 2011 with
comparative financial results included a formal project governance structure that included the Audit, Finance and Risk
Committee, senior management, and an IFRS steering committee to monitor progress and review and approve
recommendations. The IFRS transition plan progressed according to schedule and was comprehensive and addressed topics
such as the impact of IFRS on accounting policies and implementation decisions, infrastructure, business activities,
compensation matters and control activities.

METHANEX CORPORATION 2011 FOURTH QUARTER REPORT PAGE 12
MANAGEMENT’S DISCUSSION AND ANALYSIS

Anticipated changes to IFRS
Consolidation and Joint Arrangement Accounting

In May 2011, the IASB issued new accounting standards related to consolidation and joint arrangement accounting. The
IASB has revised the definition of “control,” which is a criterion for consolidation accounting. In addition, changes to IFRS
in the accounting for joint arrangements were issued which, under certain circumstances, removed the option for
proportionate consolidation accounting so that the equity method of accounting for such interests would need to be
applied. The impact of applying consolidation accounting or equity accounting does not result in any change to net
earnings or shareholders” equity, but would result in a significant presentation impact. We are currently assessing the
impact of these standards on our financial statements. We currently account for our 63.1% interest in Atlas Methanol
Company using proportionate consolidation accounting and this represents the most significant potential change under
these new standards. The effective date for these standards is for periods commencing on or after January 1, 2013, with
earlier adoption permitted.

Leases

As part of their global conversion project, the International Accounting Standards Board (IASB) and the U.S. Financial
Accounting Standards Board (“FASB”) issued a joint Exposure Draft in 2010 proposing that lessees would be required to
recognize all leases on the statement of financial position. We have a fleet of ocean-going vessels under time charter
agreements with terms of up to 15 years, which are currently accounted for as operating leases. The proposed rules would
require these time charter agreements to be recorded on the Consolidated Statements of Financial Position, resulting in a
material increase to total assets and liabilities. The IASB and FASB currently expect to issue a re-exposed draft in 2012.

ADDITIONAL INFORMATION — SUPPLEMENTAL NON-IFRS MEASURES

In addition to providing measures prepared in accordance with International Financial Reporting Standards (IFRS), we
present certain supplemental non-IFRS measures. These are Adjusted EBITDA and Adjusted cash flows from operating
activities. These measures do not have any standardized meaning prescribed by IFRS and therefore are unlikely to be
comparable to similar measures presented by other companies. These supplemental non-IFRS measures are provided to
assist readers in determining our ability to generate cash from operations. We believe these measures are useful in
assessing operating performance and liquidity of the Company’s ongoing business on an overall basis. We also believe
Adjusted EBITDA is frequently used by securities analysts and investors when comparing our results with those of other
companies.

These measures should be considered in addition to, and not as a substitute for, net income, cash flows and other measures
of financial performance and liquidity reported in accordance with IFRS.

Adjusted EBITDA (attributable to Methanex shareholders)

Adjusted EBITDA differs from the most comparable IFRS measure, cash flows from operating activities, because ¡it does not
include changes in non-cash working capital, other cash payments related to operating activities, share-based compensation
excluding mark-to-market impact, other non-cash items, taxes paid, finance income and other expenses, and Adjusted
EBITDA associated with the 40% non-controlling interest in the methanol facility in Egypt.

However, forward-looking statements, by their nature, involve risks and uncertainties that could cause actual results to differ

materially from those contemplated by the forward-looking statements. The risks and uncertainties primarily include those

attendant with producing and marketing methanol and successfully carrying out major capital expenditure projects in

various jurisdictions, including without limitation:

e conditions in the methanol and other industries,
including fluctuations in supply, demand and price for
methanol and its derivatives, including demand for
methanol for energy uses,

e the price of natural gas, oil and oil derivatives,

e the success of natural gas exploration and development
activities in southern Chile and New Zealand and our
ability to obtain any additional gas in Chile, New
Zealand, and Canada on commercially acceptable terms,

e the ability to successfully carry out corporate initiatives
and strategies,

e actions of
institutions,

competitors, suppliers, and financial

e actions of governments and governmental authorities,
including without limitation, implementation of policies
or other measures that could impact the supply or

HOW WE ANALYZE OUR BUSINESS

Our operations consist of a single operating segment – the production and sale of methanol. We review our results of operations by
analyzing changes in the components of our adjusted earnings before interest, taxes, depreciation and amortization (Adjusted
EBITDA) (refer to the Additional Information – Supplemental Non-IFRS Measures section on page 13 for a reconciliation to the most
comparable IFRS measure), mark-to-market impact of share-based compensation, depreciation and amortization, finance costs,

finance income and other expenses, and income taxes.

In addition to the methanol that we produce at our facilities (“Methanex-produced methanol”), we also purchase and re-sell
methanol produced by others (“purchased methanol”) and we sell methanol on a commission basis. We analyze the results of all
methanol sales together, excluding commission sales volumes. The key drivers of change in our Adjusted EBITDA are average

realized price, cash costs and sales volume which are defined and calculated as follows:

PRICE The change in our Adjusted EBITDA as a result of changes in average realized price is calculated as the difference
from period to period in the selling price of methanol multiplied by the current period total methanol sales volume

excluding commission sales volume plus the difference from period to period in commission income.

CASH COST The change in our Adjusted EBITDA as a result of changes in cash costs is calculated as the difference from period to
period in cash costs per tonne multiplied by the current period total methanol sales volume excluding commission
sales volume. The cash costs per tonne is the weighted average of the cash cost per tonne of Methanex-produced
methanol and the cash cost per tonne of purchased methanol. The cash cost per tonne of Methanex-produced
methanol includes absorbed fixed cash costs per tonne and variable cash costs per tonne. The cash cost per tonne of
purchased methanol consists principally of the cost of methanol itself. In addition, the change in our Adjusted
EBITDA as a result of changes in cash costs includes the changes from period to period in unabsorbed fixed

production costs, consolidated selling, general and administrative expenses and fixed storage and handling costs.

VOLUME The change in our Adjusted EBITDA as a result of changes in sales volume is calculated as the difference from period
to period in total methanol sales volume excluding commission sales volumes multiplied by the margin per tonne for
the prior period. The margin per tonne for the prior period is the weighted average margin per tonne of Methanex-
produced methanol and margin per tonne of purchased methanol. The margin per tonne for Methanex-produced
methanol is calculated as the selling price per tonne of methanol less absorbed fixed cash costs per tonne and
variable cash costs per tonne. The margin per tonne for purchased methanol is calculated as the selling price per

tonne of methanol less the cost of purchased methanol per tonne.

We own 63.1% of the Atlas methanol facility and market the remaining 36.9% through a commission offtake agreement. We
account for this investment using proportionate consolidation which results in 63.1% of the revenues and expenses being included

in our financial statements with the remaining 36.9% portion included as commission income.

We own 60% of the 1.26 million tonne per year Egypt methanol facility and market the remaining 40% through a commission
offtake agreement. We account for this investment using consolidation accounting, which results in 100% of the revenues and
expenses being included in our financial statements with the other investors” interest in the methanol facility being presented as
“non-controlling interests”. For purposes of analyzing our results, we analyze Adjusted EBITDA and Adjusted cash flows from
operating activities excluding the amounts associated with the other investors” 40% non-controlling interest and include these

results in commission income on a consistent basis with how we present the Atlas facility.

Methanex Corporation
Notes to Condensed Consolidated Interim Financial Statements (unauditea)

Except where otherwise noted, tabular dollar amounts are stated in thousands of U.S. dollars.

1. Basis of Presentation:

Methanex Corporation (the Company) is an incorporated entity with corporate offices in Vancouver, Canada. The
Company’s operations consist of the production and sale of methanol, a commodity chemical. The Company is the
world’s largest supplier of methanol to the major international markets of Asia Pacific, North America, Europe and Latin
America.

These condensed consolidated interim financial statements are prepared in accordance with International Accounting
Standards (IAS) 34, Interim Financial Reporting, as issued by the International Accounting Standards Board (IASB) on a
basis consistent with the significant accounting policies disclosed in note 2 of the March 31, 2011 interim financial
statements and therefore should be read in conjunction with the condensed consolidated interim financial statements
for the period ended March 31, 2011. These condensed consolidated interim financial statements are part of the
period covered by the Company’s first International Financial Reporting Standards (IFRS) consolidated financial
statements for the year ending December 31, 2011 and therefore IFRS 1, First Time Adoption of IFRS has been applied.
The condensed consolidated interim financial statements do not include all of the information required for full annual
financial statements and were approved and authorized for issue by the Audit, Finance € Risk Committee of the Board
of Directors on January 25, 2012.

The Company’s condensed consolidated interim financial statements were prepared in accordance with accounting
principles generally accepted in Canada (Canadian GAAP) until December 31, 2010. The period ended March 31,
2011, with comparative results for 2010, was the Company’s first IFRS condensed consolidated interim financial
statements. Canadian GAAP differs from IFRS in some areas and accordingly, the significant accounting policies
applied in the preparation of these condensed consolidated interim financial statements have been consistently applied
to all periods presented except in instances where IFRS 1 either requires or permits an exemption. An explanation of
how the transition from Canadian GAAP to IFRS has affected the reported consolidated statements of income,
comprehensive income, financial position, and cash flows of the Company for the period ended December 31, 2010 is
provided in note 13. This note includes information on the provisions of IFRS 1 and the exemptions that the Company
elected to apply at the date of transition, January 1, 2010, and reconciliations of equity, net income and comprehensive
income for the comparative period ended December 31, 2010. For a summary of the impact of transition from
Canadian GAAP to IFRS at the date of transition, January 1, 2010, as well as for the year ended December 31, 2010,
refer to note 18 of the condensed consolidated interim financial statements for the first quarter of 2011 ended March
31, 2011.

These condensed consolidated interim financial statements include the Egypt methanol facility on a consolidated basis,
with the other investors” 40% share presented as non-controlling interests, and our proportionate share of the Atlas
methanol facility.

2. Inventories:

Inventories are valued at the lower of cost, determined on a first-in first-out basis, and estimated net realizable value.
The amount of inventories included in cost of sales and operating expenses and depreciation and amortization for the
three months and year ended December 31, 2011 is $539 million (2010 – $451 million) and $2,052 million (2010 –
$1,598 million), respectively.

Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying
amount may not be recoverable. To the extent that methano!l facilities in a particular location are interdependent as a
result of common infrastructure and/or feedstock from shared sources that can be shared within a facility location,
assets are grouped based on site locations as a single cash-generating unit. The four methanol facilities at the
Company’s Chile site, the Chile oil and gas properties included in the table above, and the Chile oil and gas assets
accounted for as Other Assets are considered as a single cash generating unit (“Chile cash-generating unit”) and
production from the site was lower than expected in 2011 as a result of lower natural gas deliveries. As a
consequence, the carrying value of the Chile cash-generating unit, being $650 million on a pre-tax basis and $460
million on a postttax basis, was tested for recoverability.

Recoverability was tested by comparing the carrying value of the Chile cash-generating unit to estimated pre-tax fair
value, which was determined by measuring the pre-tax discounted cash flows expected to be generated from the assets
over their estimated useful life. There are two key variables that impact the estimate of future cash flows: (1) the
methanol price and (2) the price and availability of natural gas feedstock. Short-term methanol price estimates were
based on current supply and demand fundamentals and current methanol prices. Long-term methanol price estimates
were based on the Company’s view of long-term supply and demand and consideration was given to many factors,
including, but not limited to, estimates of global industrial production rates, energy prices, changes in general
economic conditions, future global methanol production capacity, industry operating rates and the global industry cost
structure. The Company’s estimate of the price and availability of natural gas took into consideration the current
contracted terms for supply to the methanol facilities, as well as factors influencing the exploration and development of
natural gas in southern Chile.

The estimated future cash flows were discounted to a present value using a pre-tax discount rate based on the
Company’s weighted average cost of capital. Based on the test performed, the carrying value of the Company’s Chile
cash-generating unit is recoverable.

4. Interest in Atlas joint venture:

The Company has a 63.1% joint venture interest in Atlas Methanol Company (Atlas). Atlas owns a 1.7 million tonne
per year methanol production facility in Trinidad. Included in the condensed consolidated interim financial statements
are the following amounts representing the Company’s proportionate interest in Atlas:

During the three months and year ended December 31, 2011, the Company made repayments on its Atlas limited
recourse debt facilities of $7.5 million and $15.5 million, respectively, and other limited recourse debt facilities of $0.6
million and $2.4 million, respectively. The Company also made repayments on its Egypt limited recourse debt facilities
of $31.7 million during the year ended December 31, 2011.

The covenants governing the Company’s unsecured notes apply to the Company and its subsidiaries excluding the
Atlas joint venture and Egypt entity (“limited recourse subsidiaries”) and include restrictions on liens and sale and lease-
back transactions, or merger or consolidation with another corporation or sale of all or substantially all of the
Company/’s assets. The indenture also contains customary default provisions.

5. Long-term debt (continued):

The Company has a $200 million unsecured revolving bank facility provided by highly rated financial institutions and
this was extended in early July 2011 to May 2015. This facility contains covenant and default provisions in addition to
those of the unsecured notes as described above. Significant covenants and default provisions under this facility
include:

a) the obligation to maintain an EBITDA to interest coverage ratio of greater than 2:1 and a debt to capitalization
ratio of less than or equal to 50%, calculated on a four quarter trailing average basis in accordance with definitions
in the credit agreement which include adjustments related to the limited recourse subsidiaries,

b) a default if payment is accelerated by the creditor on any indebtedness of $10 million or more of the Company
and its subsidiaries except for the limited recourse subsidiaries, and

c) a default if a default occurs on any other indebtedness of $50 million or more of the Company and its subsidiaries
except for the limited recourse subsidiaries that permits the creditor to demand repayment.

The Atlas and Egypt limited recourse debt facilities are described as limited recourse as they are secured only by the
assets of the Atlas joint venture and the Egypt entity, respectively. Accordingly, the lenders to the limited recourse debt
facilities have no recourse to the Company or its other subsidiaries. The Atlas and Egypt limited recourse debt facilities
have customary covenants and default provisions which apply only to these entities including restrictions on the
incurrence of additional indebtedness and a requirement to fulfill certain conditions before the payment of cash or
other distributions and a restriction on these distributions if there is a default subsisting.

The Egypt limited recourse debt facilities required that certain conditions associated with plant construction and
commissioning be met by September 30, 2011 (“project completion”). Project completion was achieved during the
third quarter of 2011. In connection with achieving project completion, we agreed to a covenant to complete by
March 31, 2012 certain land title registrations and related mortgages which require action by Egyptian government
entities and which we do not expect to complete by March 31, 2012 and will seek a waiver from the lenders. We do
not believe that the finalization of these items is material. We cannot assure you that we will be able to obtain a
waiver from the lenders.

Failure to comply with any of the covenants or default provisions of the long-term debt facilities described above could
result in a default under the applicable credit agreement that would allow the lenders to not fund future loan requests
and to accelerate the due date of the principal and accrued interest on any outstanding loans.

At December 31, 2011, management believes the Company was in compliance with all of the covenants and default
provisions related to long-term debt obligations.

$ 17,868 $ 7,396 $ 61,797 $ 30,648

Finance costs are primarily comprised of interest on borrowings and finance lease obligations, amortization of deferred
financing fees, and accretion expense associated with site restoration costs. Interest during construction of the Egypt
methanol facility was capitalized until the plant was substantially completed and ready for productive use in mid-
March of 2011. The Company has interest rate swap contracts on its Egypt limited recourse debt facilities to swap the
LIBOR-based interest payments for an average aggregated fixed rate of 4.8% plus a spread on approximately 75% of
the Egypt limited recourse debt facilities for the period of September 28, 2007 to March 31, 2015.

8. Net income per common share:

Diluted net income per common share is calculated by giving effect to the potential dilution that would occur if
outstanding stock options and tandem share appreciation rights (TSARs) were exercised or converted to common
shares. Outstanding TSARs may be settled in cash or common shares at the holder’s option and for purposes of
calculating diluted net income per common share, the more dilutive of cash-settled and equity-settled is used,
regardless of how the plan is accounted for. Accordingly, TSARs which are accounted for as cash-settled for
accounting purposes will require an adjustment to the numerator and denominator if they are determined to have a
dilutive effect on diluted net income per common share.

During the year ended December 31, 2011, the Company’s share price declined and the Company recorded a share
based compensation recovery related to TSARs. For the year ended December 31, 2011, the equity-settled method has
been determined to be the more dilutive for purposes of calculating diluted net income per common share.

A reconciliation of the net income used for the purpose of calculating diluted net income per common share is as

(2010 – $1.4 million), respectively. The fair value of the stock option grant was estimated on the date of grant

using the Black-Scholes option pricing model.

b) Share appreciation rights and tandem share appreciation rights:

During 2010, the Company’s stock option plan was amended to include tandem share appreciation rights (TSARs)
and a new plan was introduced for share appreciation rights (SARs). A SAR gives the holder a right to receive a
cash payment equal to the amount the market price of the Company’s common shares exceeds the exercise price.
A TSAR gives the holder the choice between exercising a regular stock option or surrendering the option for a cash
payment equal to the amount the market price of the Company’s common shares exceeds the exercise price. All
SARs and TSARs granted have a maximum term of seven years with one-third vesting each year after the date of

grant.

b) Share appreciation rights and tandem share appreciation rights (continued):
(ii) Compensation expense related to SARs and TSARs:

Compensation expense for SARs and TSAR:s is initially measured based on their fair value and is recognized
over the related service period. Changes in fair value each period are recognized in earnings for the
proportion of the service that has been rendered at each reporting date. The fair value at December 31, 2011
was $6.3 million compared with the recorded liability of $5.0 million. The difference between the fair value
and the recorded liability of $1.3 million will be recognized over the weighted average remaining service
period of approximately 1.7 years. The weighted average fair value of the vested SARs and TSARs was
estimated at December 31, 2011 using the Black-Scholes option pricing model.

For the three months and year ended December 31, 2011, compensation expense related to SARs and TSARs
included an expense in cost of sales and operating expenses of $1.0 million (2010 – $4.2 million) and a
recovery of $3.5 million (2010 – expense of $8.6 million), respectively. This included an expense of $0.1
million (2010 – $3.4 million) and a recovery of $10.4 million (2010 – expense of $3.0 million) related to the
effect of the change in the Company’s share price for the three months and year ended December 31, 2011
respectively.

Compensation expense for deferred, restricted and performance share units is measured at fair value based on the
market value of the Company’s common shares and is recognized over the related service period. Changes in fair
value are recognized in earnings for the proportion of the service that has been rendered at each reporting date.
The fair value of deferred, restricted and performance share units at December 31, 2011 was $38.0 million
compared with the recorded liability of $35.5 million. The difference between the fair value and the recorded
liability of $2.5 million will be recognized over the weighted average remaining service period of approximately
1.4 years.

For the three months and year ended December 31, 2011, compensation expense related to deferred, restricted
and performance share units included in cost of sales and operating expenses was an expense of $2.6 million
(2010 – $13.6 million) and a recovery of $2.2 million (2010 – expense of $26.0 million), respectively. This
included an expense of $1.2 million (2010 – $11.9 million) and a recovery of $10.9 million (2010 – expense of
$16.4 million) related to the effect of the change in the Company’s share price for the three months and year
ended December 31, 2011, respectively.

Financial instruments (continued):

At December 31, 2011, all of the Company’s financial instruments are recorded on the balance sheet at amortized cost
with the exception of cash and cash equivalents, derivative financial instruments and project financing reserve accounts
included in other assets which are recorded at fair value.

The Egypt limited recourse debt facilities bear interest at LIBOR plus a spread. The Company has interest rate swap
contracts to swap the LIBOR-based interest payments for an average aggregated fixed rate of 4.8% plus a spread on
approximately 75% of the Egypt limited recourse debt facilities for the period to March 31, 2015. The Company has
designated these interest rate swaps as cash flow hedges.

These interest rate swaps had outstanding notional amounts of $367 million as at December 31, 2011. The notional
amounts decrease over the expected repayment period. At December 31, 2011, these interest rate swap contracts had a
negative fair value of $41.5 million (2010 – $43.5 million) recorded in other long-term liabilities. The fair value of these
interest rate swap contracts will fluctuate until maturity. The Company also designates as cash flow hedges forward
exchange contracts to sell euro at a fixed USD exchange rate. At December 31, 2011, the Company had outstanding
forward exchange contracts designated as cash flow hedges to sell a notional amount of 28.2 million euro in exchange
for US dollars and these euro contracts had a positive fair value of $0.3 million recorded in trade and other receivables.
Changes in fair value of derivative financial instruments designated as cash flow hedges have been recorded in other
comprehensive income.

The Company has entered into natural gas purchase agreements related its Medicine Hat facility at fixed prices ranging
from $3.79/mmbtu to $4.50/mmbtu. The contracts cover approximately 80% of the natural gas requirements when
operating the facility at capacity to March 2013 and approximately 50% of the requirements for the period from April
2013 to October 2013.

Contingent Liability:

The Board of Inland Revenue of Trinidad and Tobago issued an assessment in 2011 against our 63.1% owned joint
venture, Atlas Methanol Company Unlimited (“Atlas”), in respect of the 2005 financial year. All subsequent tax years
remain open to assessment. The assessment relates to the pricing arrangements of certain long-term fixed price sales
contracts related to methanol produced by Atlas that extend to 2014 and 2019. The impact of the amount in dispute
for the 2005 financial year is nominal as Atlas was not subject to corporation income tax in that year. Atlas has partial
relief from corporation income tax until 2014.

The Company has lodged an objection to the assessment. Based on the merits of the case and legal interpretation,
management believes its position should be sustained.

13. Transition to International Financial Reporting Standards:

For a description of the significant IFRS accounting policies, refer to note 2 of the condensed consolidated interim
financial statements for the first quarter ended March 31, 2011. Those IFRS accounting policies have been applied in
preparing the condensed consolidated interim financial statements for the three months and year ended December 31,
2011, the comparative information presented in these interim financial statements for the three months and year ended
December 31, 2010, the year ended December 31, 2010 and in the preparation of an opening IFRS statement of
financial position at January 1, 2010, the Company’s date of transition. An explanation of the IFRS 1 exemptions and
the required reconciliations between IFRS and Canadian GAAP are described below:

IFRS 1 First-Time Adoption of International Financial Reporting Standards

In preparing these condensed consolidated interim financial statements, the Company has applied IFRS 1, First-time
Adoption of International Financial Reporting Standards, which provides guidance for an entity’s initial adoption of
IFRS. IFRS 1 gives entities adopting IFRS for the first time a number of optional and mandatory exceptions, in certain
areas, to the general requirement for full retrospective application of IFRS. The following are the optional exemptions
available under IFRS 1 that the Company has elected to apply:

Business combinations

The Company has elected to apply IFRS 3, Business Combinations, prospectively to business combinations that occur
after the date of transition. The Company has elected this exemption under IFRS 1, which removes the requirement to
retrospectively restate all business combinations prior to the date of transition to IFRS.

Employee benefits

The Company has elected to recognize all cumulative actuarial gains and losses on defined benefit pension plans
existing at the date of transition immediately into retained earnings, rather than continuing to defer and amortize into
the results of operations. Refer to note 18 (b) of the March 31, 2011 condensed consolidated interim financial
statements for the impact on transition to IFRS.

Fair value or revaluation as deemed cost

The Company has used the amount determined under a previous GAAP revaluation as the deemed cost for certain
assets. The Company elected the exemption for certain assets which were written down under Canadian GAAP, as the
revaluation was broadly comparable to fair value under IFRS. The carrying value of those assets on transition to IFRS is
therefore, consistent with the Canadian GAAP carrying value on the transition date.

Share-based payments

The Company elected to not apply IFRS 2, Share-based Payments, to equity instruments granted before November 7,
2002 and those granted but fully vested before the date of transition to IFRS. As a result, the Company has applied IFRS
2 for stock options granted after November 7, 2002 that were not fully vested at January 1, 2010.

Site restoration costs

The Company has elected to apply the IFRS 1 exemption whereby it has measured the site restoration costs at January
1, 2010 in accordance with the requirements in IAS 37, Provisions, by estimating the amount that would have been in
property, plant and equipment when the liabilities first arose, and discounted the transition date liability to that date

Reconciliations between IFRS and Canadian GAAP

IFRS 1 requires an entity to reconcile equity, comprehensive income and cash flows for comparative periods. The
Company’s adoption of IFRS did not have a significant impact on total operating, investing or financing cash flows in
the prior periods. However, it did result in some presentation changes. Under Canadian GAAP, interest paid included
in profit and loss was classified as operating activities and capitalized interest was classified as investing activities.
Under IFRS, interest paid, including capitalized interest, is classified as financing activities. There were no other
significant adjustments to the statement of cash flows. In preparing these condensed consolidated interim financial
statements, the Company has adjusted amounts reported previously in financial statements prepared in accordance
with Canadian GAAP. An explanation of how the transition from Canadian GAAP to IFRS has affected the Company’s
statements of financial position, income, and comprehensive income ¡is provided below:

13. Transition to International Financial Reporting Standards (continued):
The items noted above in the reconciliations of the statement of financial position, income and comprehensive income
from Canadian GAAP to IFRS are described below:

a)

b)

o)

d)

Leases:

Under Canadian GAAP, an arrangement at inception that can only be fulfilled through the use of a specific asset or
assets, and which conveys a right to use that asset, may be a lease or contain a lease. Regardless of whether the
arrangement takes the legal form of a lease, an asset and corresponding liability should be recorded. However,
Canadian GAAP has grandfathering provisions that exempt contracts entered into before 2004 from these
requirements.

IFRS has similar accounting requirements as Canadian GAAP for lease-like arrangements, with IFRS requiring full
retrospective application. The Company has long-term oxygen supply contracts for its Atlas and Titan methanol
plants in Trinidad, executed prior to 2004, which are regarded as finance leases under these standards.
Accordingly, the oxygen supply contracts are required to be accounted for as finance leases from original inception
of the lease. The Company measured the value of these finance leases and applied finance lease accounting
retrospectively from inception to determine the IFRS impact. As at December 31, 2010 this results in an increase to
property, plant and equipment of $55.1 million and other long-term liabilities of $68.6 million with a
corresponding decrease to retained earnings of $13.5 million.

In comparison to Canadian GAAP, for the three months and year ended December 31, 2010, this accounting
treatment resulted in lower cost of sales and operating costs, higher finance costs and higher depreciation and
amortization charges, with no significant impact to net earnings.

Employee benefits:

The Company elected the IFRS 1 exemption to recognize all cumulative actuarial gains and losses on defined
benefit pension plans existing at the date of transition immediately in retained earnings. As at December 31, 2010
this results in a decrease to retained earnings of $17.8 million, a decrease to other assets of $12.1 million and an
increase to other long-term liabilities of $5.7 million.

In comparison to Canadian GAAP for the three months and year ended December 31, 2010, net earnings
decreased by approximately $1.1 million and $0.1 million, respectively. This includes an adjustment to the
Company’s 2010 financial statements as previously reported under IFRS to reflect the impact of foreign exchange
on the cumulative actuarial losses as reported.

Site restoration costs:

Under IFRS, the Company recognizes a liability to dismantle and remove assets or to restore a site upon which the
assets are located. The Company is required to determine a best estimate of site restoration costs for all sites
whereas under Canadian GAAP site restoration costs were not recognized with respect to assets with indefinite or
indeterminate lives. In addition, under IFRS a change in the market-based discount rate will result in a change in
the measurement of the provision. As at December 31, 2010, adjustments to the financial statements to recognize
site restorations costs are recognized as an increase to other long-term liabilities of approximately $7.7 million and
an increase to property, plant and equipment of approximately $3.6 million, with the balancing amount recorded
as a decrease to retained earnings to reflect the depreciation expense and interest accretion since the date the
liabilities first arose. In comparison to Canadian GAAP for the three months and year ended December 31, 2010,
there was no significant impact to net earnings.

Borrowing costs:

IAS 23 prescribes the accounting treatment and eligibility of borrowing costs. The Company has entered into
interest rate swap contracts to hedge the variability in LIBOR-based interest payments on its Egypt limited recourse
debt facilities. Under Canadian GAAP, cash settlements for these swaps during construction are recorded in
accumulated other comprehensive income for the Company’s 60% portion and 40% is recorded in non-controlling
interest. Under IFRS, the cash settlements during construction are recorded to property, plant and equipment.
Accordingly, there is an increase to property, plant and equipment of approximately $24.0 million at December
31, 2010. The increase to property, plant and equipment is offset by an increase to accumulated other
comprehensive income of approximately $14.4 million and an increase in non-controlling interest of
approximately $9.6 million at December 31, 2010, with no impact on net earnings.

Uncertain tax positions:

IAS 12 prescribes recognition and measurement criteria of a tax position taken or expected to be taken in a tax
return. As at December 31, 2010, this resulted in an increase to income tax liabilities and a decrease to retained
earnings of approximately $7.2 million in comparison to Canadian GAAP. For the three months and year ended
December 31, 2010 this has resulted in a decrease in net earnings of $0.7 million and $1.8 million, respectively,
with a corresponding increase to income tax liabilities.

Share-based payments:

During 2010, the Company made its first grant of SARs and TSARs in connection with the employee long-term
incentive compensation plan.

Under Canadian GAAP, both SARs and TSARs are accounted for using the intrinsic value method. The intrinsic
value related to SARs and TSARs is measured by the amount the market price of the Company’s common shares
exceeds the exercise price of a unit. Changes in intrinsic value each period are recognized in earnings for the
proportion of the service that has been rendered at each reporting date. Under IFRS, SARs and TSARs are required
to be accounted for using a fair value method. The fair value related to SARs and TSARs is estimated using an
option pricing model. Changes in fair value estimated using an option pricing model each period are recognized
in earnings for the proportion of the service that has been rendered at each reporting date.

The fair value estimated using an option pricing model will be higher than the intrinsic value due to the time value
included in the estimated fair value. Accordingly, it is expected that the difference between the accounting
expense under IFRS compared with Canadian GAAP would be higher near the beginning of the life of a SAR or
TSAR with this difference narrowing as time passes and with total accounting expense ultimately being the same
on the date of exercise.

The difference in the fair value method under IFRS compared with the intrinsic value method under Canadian
GAAP, has resulted in a decrease to net earnings of approximately $0.7 million and $4.6 million for the three
months and year ended December 31, 2010, respectively. The difference in the fair value method under IFRS
compared with the intrinsic value method under Canadian GAAP resulted in an increase to other long-term
liabilities of approximately $5.7 million and corresponding decrease to shareholders” equity as at December 31,
2010.

Deferred tax impact and other adjustments:

This adjustment primarily represents the income tax effect of the adjustments related to accounting differences
between Canadian GAAP and IFRS. As at December 31, 2010, this has resulted in a decrease to deferred tax
liabilities and increase to retained earnings of approximately $10.5 million. For the three months and year ended
December 31, 2010, this has resulted in an increase in net earnings of $0.7 million and $1.8 million respectively.

Reclassification of non-controlling interests from liabilities:

The Company has a 60% interest in EMethanex, the Egyptian company through which it has developed the
Egyptian methanol project. The Company accounts for this investment using consolidation accounting which
results in 100% of the assets and liabilities of EMethanex being included in the financial statements. The other
investors” interest in the project is presented as “non-controlling interests”. Under Canadian GAAP, the non-
controlling interests is classified as a liability whereas under IFRS the non-controlling interests is classified as
equity, but presented separately from the parent’s shareholder equity. This reclassification results in a decrease to
liabilities and an increase in equity of approximately $156.4 million as at December 31, 2010.

Investment in associates:

In 2010, the Company had a 20% equity interest in a DME production facility in China. The Company also had a
methanol sales agreement to supply methanol to this facility and these adjustments represent the difference
between Canadian GAAP and IFRS in the timing of recognition of earnings associated with methanol sales to the
equity investment.
