METHANEX REPORTS FIRST QUARTER RESULTS AND INCREASES DIVIDEND 10%; EGYPT AND MEDICINE HAT
PLANTS IN PRODUCTION

APRIL 27, 2011

For the first quarter of 2011, Methanex reported Adjusted EBITDA’ of $77.1 million and net income attributable to
Methanex shareholders of $34.6 million ($0.37 per share on a diluted basis). This compares with Adjusted EBITDA!’ of
$73.0 million and net income attributable to Methanex shareholders of $27.0 million ($0.29 per share on a diluted basis)
for the fourth quarter of 2010.

Methanex also announced that its Board of Directors has approved a 10 percent increase to its quarterly dividend to
shareholders, from US$0.155 to US$0.17 per share. The increased dividend will apply commencing with the dividend
payable on June 30, 2011 to holders of common shares of record on June 16, 2011.

Bruce Aitken, President and CEO of Methanex commented, “Methanol pricing continued to be firm in the first quarter and
we reported similar earnings to last quarter. Entering the second quarter, methanol demand continues to be strong and
industry conditions remain relatively balanced.”

Mr. Aitken added, “I am delighted to report that the Egypt plant began shipments earlier this month and the Medicine Hat
plant produced first methanol last week. With the increased production and cash flow generation these plants provide and
the positive outlook for the methanol industry, we are pleased to announce an increase to our regular dividend. This
increase represents the seventh time we have increased our dividend since it was implemented in 2002.”

Mr. Aitken concluded, “We have a strong balance sheet with US$240 million of cash on hand and an undrawn credit
facility, and we believe we are well positioned to continue to invest to grow the Company.”

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. Practical operating
capacity will depend partially on the composition of natural gas feedstock and may differ from the stated capacity above. We also have additional potential
production capacity that is currently idled in New Zealand (refer to the New Zealand section on page 3 for more information).

The new Egypt methanol facility commenced production in mid-March 2011. We are currently commissioning our Medicine Hat, Alberta facility (refer to the
Egypt and Medicine Hat sections on page 3 for more information).

Chile

During the first quarter of 2011, we produced 183,000 tonnes in Chile operating one plant at approximately 60% capacity.
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.

Our 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 in southern Chile. Under the arrangement, we fund a 50% participation in the block and, as at March 31, 2011, we
had contributed approximately $91 million. Over the past few years, we have also provided GeoPark with $57 million (of
which approximately $37 million had been repaid at March 31, 2011) to support and accelerate GeoPark’s natural gas
exploration and development activities in southern Chile. GeoPark has agreed to supply us with all natural gas sourced
from the Fell block in southern Chile under a ten-year exclusive supply arrangement that commenced in 2008. During the
first quarter of 2011 approximately 55% of total 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. In late 2007, the government of Chile completed an international bidding round to assign oil and natural
gas exploration areas that lie close to our production facilities and announced the participation of several international oil
and gas companies. The terms of the agreements from the bidding round require minimum investment commitments. To
date, two companies that participated in the bidding round have advised of gas discoveries. We are participating in a
consortium for two exploration blocks under this bidding round – the Tranquilo and Otway blocks. The consortium
includes Methanex, Wintershall, GeoPark, Pluspetrol and International Finance Corporation, member of the World Bank
Group. We have approximately 15% participation in the consortium. At March 31, 2011, we had contributed
approximately $3 million for our share of the exploration costs associated with these blocks.

Lower production at our Chile facilities during the first quarter of 2011 compared with the fourth quarter of 2010 was due
to lower natural gas deliveries to our plants in southern Chile. While significant investments have been made in the last few
years for natural gas exploration and development in southern Chile, the timelines for a significant increase in gas deliveries
to our plants are much longer than we originally anticipated and the short-term outlook for gas supply in Chile continues to
be challenging. As we enter the southern hemisphere winter months when residential energy demand is at its peak, there is
increased pressure on short-term natural gas supply/demand fundamentals in southern Chile and increased risk that gas
supply to our plant could fall below the level necessary to maintain the operation of one plant.

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

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 over changes in the level of natural gas supply or that we will
be able to source sufficient natural gas to operate any capacity in Chile 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 competitive-cost annual
capacity. During the first quarter of 2011, these facilities produced 384,000 tonnes compared with 499,000 tonnes during
the fourth quarter of 2010. Production at these facilities was lower by 115,000 tonnes during the first quarter of 2011
compared with the fourth quarter of 2010 primarily as a result of unplanned maintenance activities completed at the Titan
facility which lasted approximately 35 days during the first quarter of 2011.

New Zealand

Our New Zealand facilities provide competitive-cost capacity and are underpinned by shorter term natural gas supply
contracts. During the first quarter of 2011, we produced 203,000 tonnes compared with 206,000 tonnes during the fourth
quarter of 2010. We are currently operating one 850,000 tonne per year plant at our Motunui facility in New Zealand and
we have natural gas contracts with a number of gas suppliers that will allow us to continue to operate this plant through
2012. We also have an additional 1.38 million tonnes per year of idled capacity in New Zealand, including a second
850,000 tonne per year Motunui plant and a 530,000 tonne per year plant at our nearby site in Waitara Valley. These
facilities provide the potential to increase production in New Zealand depending on the methanol supply and demand
dynamics and the availability of economically priced natural gas feedstock. We believe there has been continued
improvement in the natural gas supply outlook in New Zealand and we are focused on accessing additional natural gas
supply to increase production in New Zealand. We are continuing to pursue opportunities to obtain economically priced
natural gas with suppliers in New Zealand to underpin a restart of a second plant.

Egypt

The new 1.26 million tonne per year methanol plant in Egypt produced first methanol in January 2011. The start-up
coincided with widespread anti-government protests and civil unrest in Egypt. For the safety and security of our employees,
we took the decision to temporarily close our Cairo office and curtail the commissioning activities at the plant in Damietta,
Egypt. As conditions stabilized, we reopened our Cairo office and our plant in Damietta resumed operations to continue the
startup and commissioning process.

Since mid-March 2011, the Egypt methanol plant has operated well, producing 51,000 tonnes (60% interest – 31,000
tonnes) of methanol during the first quarter of 2011 with shipments commencing in early April. We have a 60% interest in
the facility and have marketing rights for 100% of the production. This facility is underpinned by a 25-year take-or-pay
natural gas purchase agreement where the gas price varies with methanol prices. We believe this methanol facility will
further enhance our cost structure and our market position and it is well located to supply the European market.

Medicine Hat

We are currently commissioning our 470,000 tonne per year facility in Medicine Hat, Alberta and the plant produced first
methanol in late April 2011. We have a program in place to purchase natural gas on the Alberta gas market and to date we
have contracted sufficient volumes of natural gas to meet approximately 80% of our requirements when operating at
capacity for the period from start-up to October 2012.

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

EARNINGS ANALYSIS

Our operations consist of a single operating segment – the production and sale of methanol. In addition to the methanol
that we produce at our facilities, we also purchase and re-sell methanol produced by others 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 for methanol sales are average realized price, sales volume and cash costs.

For a further discussion of the definitions and calculations used in our Adjusted EBITDA analysis, refer to How We Analyze
Our Business.

For the first quarter of 2011, we recorded Adjusted EBITDA of $77.1 million and net income attributable to Methanex
shareholders of $34.6 million ($0.37 per share on a diluted basis). This compares with Adjusted EBITDA of $73.0 million
and net income attributable to Methanex shareholders of $27.0 million ($0.29 per share on a diluted basis) and Adjusted
EBITDA of $80.9 million and net income attributable to Methanex shareholders of $27.0 million ($0.29 per share on a
diluted basis) for the fourth and first quarters of 2010, respectively.

During 2010, methanol demand growth was strong with increases in demand primarily driven by both traditional and
energy derivatives in Asia (particularly in China). Into the first quarter of 2011, demand continued to be strong and the
industry operated at moderately higher utilization rates. As a result, market conditions have been balanced and the pricing
environment has been relatively stable (refer to Supply/Demand Fundamentals section on page 8 for more information).
Our average non-discounted posted price for the first quarter of 2011 was $436 per tonne compared with $407 per tonne
for the fourth quarter of 2010. Our average realized price for the first quarter of 2011 was $367 per tonne compared with
$348 per tonne for the fourth quarter of 2010 and this increased revenue by $32 million.

Sales volume

Total methanol sales volumes excluding commission sales volumes for the first quarter of 2011 were higher compared with
the fourth quarter of 2010 and the first quarter of 2010 by 46,000 tonnes and 155,000 tonnes, respectively. The higher
sales volumes for the first quarter of 2011 compared with the fourth quarter of 2010 and the first quarter of 2010 resulted in
higher Adjusted EBITDA by $4 million and $13 million, respectively.

METHANEX CORPORATION 2011 FIRST QUARTER REPORT PAGE 4
MANAGEMENT’S DISCUSSION AND ANALYSIS

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. Most of our production facilities 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 natural gas costs 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:

Q1 2011 Q1 2011

compared with compared with

($ millions) Q4 2010 Q1 2010
Produced methanol costs, primarily natural gas $ (18) $ (37)
Proportion of purchased methanol sales (1) (50)
Purchased methanol costs (21) (27)
Share-based compensation 8 3
Unabsorbed fixed costs (3) (5)
Other, net 3 (6)
Decrease in Adjusted EBITDA $ (32) $ (122)

Produced methanol costs, primarily natural gas

Natural gas costs on sales of produced methanol for the first quarter of 2011 were higher than comparable periods in 2010,
primarily as a result of higher methanol pricing.

Proportion of purchased methanol sales

The cost of purchased methanol is directly linked to the selling price for methanol at the time of purchase and the cost of
purchased methanol is generally higher than the cost of produced methanol. Accordingly, an increase in the proportion of
purchased methanol sales results in an increase in our overall cost structure for a given period. The proportion of purchased
methano!l sales for the first quarter of 2011 was higher for the comparable periods noted above.

Purchased methanol costs

Purchased methanol costs were higher for the first quarter of 2011 compared with the periods noted above, primarily as a
result of higher methanol pricing and timing of inventory flows.

Share-based compensation

We grant share-based awards as an element of compensation. Share-based awards granted include stock options, share
appreciation rights, tandem share appreciation rights, deferred share units, restricted share units and performance share
units.

For stock options, the cost is measured based on an estimate of the fair value at the date of grant 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, stock-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 as a result of our initiative to reduce dilution to shareholders. SARs and TSARSs are units
that grant the holder the right to receive a cash payment upon exercise for the difference between the market price of the
Company’s common shares and the exercise price, which is determined at the date of grant. SARs and TSARs are measured
based on estimated fair value, which is determined using the Black-Scholes option pricing model.

METHANEX CORPORATION 2011 FIRST QUARTER REPORT PAGE 5
MANAGEMENT’S DISCUSSION AND ANALYSIS

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.

For all the share-based awards with the exception of stock options, the initial value and any subsequent change in fair value
is recognized in earnings over the related service period for the proportion of the service that has been rendered at each
reporting date. Accordingly, share-based compensation associated with these share-based awards may vary significantly
from period to period as a result of changes in the share price.

Share-based compensation expense for the first quarter of 2011 was $10 million compared with $18 million for the fourth
quarter of 2010 and $13 million for the first quarter of 2010. Share-based compensation expense was lower by $8 million
and $3 million, respectively, primarily due to a smaller increase in the share price in the first quarter of 2011 compared
with these periods.

Unabsorbed fixed costs

Unabsorbed fixed costs for the first quarter of 2011 were higher by $3 million compared with the fourth quarter of 2010
and higher by $5 million compared with the first quarter of 2010 primarily as a result of lower production at our Titan
facility in Trinidad during the first quarter of 2011 compared with these periods.

Other, net

For the first quarter of 2011 compared with the fourth quarter of 2010, ocean freight and other logistics costs were lower by
approximately $3 million primarily as a result of higher backhaul cost recoveries.

For the first quarter of 2011 compared with the first quarter of 2010, other costs were higher by approximately $6 million
primarily as a result of higher in-market distribution costs which are substantially recovered in revenues and timing of
selling, general and administrative costs.

Depreciation and Amortization

Depreciation and amortization was $30 million for the first quarter of 2011 compared with $32 million for the fourth
quarter of 2010 and $35 million for the first quarter of 2010.

Finance income and other expenses for the first quarter of 2011 was $5 million compared with $4 million for the fourth
quarter of 2010 and $1 million for the first quarter of 2010. The increase in finance income during the first quarter of 2011
compared with the fourth quarter of 2010 and the first quarter of 2010 was primarily due to the impact of changes in
foreign exchange rates.

Income Taxes

We recorded income tax expense of $9.5 million for the first quarter of 2011 compared with $11.2 million for the fourth
quarter of 2010 and $12.8 million for the first quarter of 2010. The effective tax rate for the first quarter of 2011 was
approximately 22% compared with approximately 29% for the fourth quarter of 2010 and approximately 33% for the first
quarter of 2010. The lower tax rate in the first quarter of 2011 compared with the fourth quarter of 2010 and the first
quarter of 2010 was primarily due to a higher proportion of our income being earned in lower tax jurisdictions in the first
quarter of 2011.

The statutory tax rate in Chile and Trinidad, where we earn a substantial portion of our pre-tax earnings, is 35%. Our Atlas
facility in Trinidad has partial relief from corporation income tax until 2014. 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 future income tax expense and is subsequently reclassified to current income tax
expense when earnings are distributed.

MANAGEMENT’S DISCUSSION AND ANALYSIS

SUPPLY/DEMAND FUNDAMENTALS

During 2010, methanol demand growth was strong, increasing by 13% to a total of approximately 45 million tonnes.
Increases in demand have been primarily driven by both traditional and energy derivatives in Asia (particularly in China).
More recently, we have also seen increases in traditional derivative demand in other regions including Europe and North
America.

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 *

application is supported by recent regulatory changes in that
country. For example, an M85 (or 85% methanol) national

standard took effect December 1, 2009, and we expect an M15
(or 15% methanol) national standard to be released in 2011. We believe demand potential into energy derivatives will be
stronger in a high energy price environment.

During the first quarter of 2011, demand continued to be strong and the industry operated at slightly higher utilization
rates. As a result, market conditions have been balanced and the pricing environment has been relatively stable. Our
average non-discounted price for April 2011 is approximately $420 per tonne compared to an average price of $436 for the
first quarter of 2011. We recently announced our North America non-discounted price for May at $426 per tonne which is
unchanged from April.

Our 1.26 million tonne per year plant in Egypt commenced shipments in early April and our 470,000 tonne plant in
Medicine Hat produced first methanol in late April. Beyond this, there is little new capacity expected to come on-stream
outside China over the next few years. There is a 0.85 million tonne plant expected to restart in Beamount, Texas in 2012
and a 0.7 million tonne plant expected to start up in Azerbaijan in 2013.

LIQUIDITY AND CAPITAL RESOURCES

Cash flows from operating activities before changes in working capital in the first quarter of 2011 were $80 million
compared with $94 million for the fourth quarter of 2010 and $91 million for the first quarter of 2010.

During the first quarter of 2011, we paid a quarterly dividend of US$0.155 per share, or $14 million. Additionally, the
Board of Directors has approved a 10 percent increase to our quarterly dividend to shareholders, from US$0.155 to
US$0.17 per share. The increased dividend will apply commencing with the dividend payable on June 30, 2011 to holders
of common shares of record on June 16, 2011.

During the first quarter of 2011, approximately $21 million in costs were capitalized to the Egypt plant under construction.
During the first quarter of 2011, a debt principal payment of $16 million was paid on the Egypt limited recourse debt
facilities. At March 31, 2011, management believes the Company was in compliance with all of the covenants and default
provisions related to long-term debt obligations.

We have agreements in place to participate in or support natural gas exploration and development in southern Chile.
During the first quarter of 2011, we paid $6 million to fund natural gas exploration and development in the Dorado
Riquelme block. During the first quarter of 2011, GeoPark repaid $5 million through natural gas deliveries to our plants in
southern Chile (refer to the Production Summary section on page 2 for more information).

METHANEX CORPORATION 2011 FIRST QUARTER REPORT PAGE 8
MANAGEMENT’S DISCUSSION AND ANALYSIS

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 March 31, 2011 was $240 million. We have a strong
balance sheet, no near term re-financing requirements, and an undrawn $200 million credit facility provided by highly
rated financial institutions that expires in mid-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 $75 million for the period to the end of 2012. We are currently
commissioning our 470,000 tonne per year methanol plant in Medicine Hat. The estimated capital cost for this restart ¡is
approximately $45 million, of which approximately $32 million was incurred to March 31, 2011 with the remainder to be

incurred in the second quarter of 2011.

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

SHORT-TERM OUTLOOK

Into the second quarter of 2011, demand continues to be strong and we expect market conditions to remain relatively
balanced.

We anticipate a significant increase in our production into the second quarter of 2011. The new 1.26 million tonne per year
methanol facility in Egypt has been operating well since mid-March and shipments began in early April. We are currently
commissioning our 470,000 tonne per year plant in Medicine Hat, Alberta with production of first methanol in late April.
With the addition of these two production sites, we are well positioned to increase our production and earnings capability
this year.

The methanol price will ultimately depend on the strength of the global economy, industry operating rates, global energy
prices, 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 March 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 quarter ending March 31, 2011 with comparative financial results for 2010, is our first interim period reported under
IFRS. All comparative figures 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 MD8A in the 2010 Annual Report, we disclosed the significant impacts on transition to IFRS. The
disclosure in our MDKA 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.

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 18 of the condensed consolidated interim financial statements for the reconciliations between IFRS and Canadian
GAAP.

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 expected to elect 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 18 of the condensed consolidated
interim financial statements 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.

Anticipated changes to IFRS
Consolidation and Joint Venture Accounting

The IASB ¡s currently proceeding on projects related to consolidation and joint venture accounting. The IASB is revising the
definition of “control,” which is a criterion for consolidation accounting. In addition, future changes to IFRS in the
accounting for joint ventures are expected and these changes may remove the option for proportionate consolidation and
allow only the equity method of accounting for such interests. The impact of applying consolidation accounting or the
equity method of accounting does not result in any change to net earnings or shareholders” equity, but would result in a
significant presentation impact. The impact these projects may ultimately have on the conclusions related to the accounting
treatment of our interest in joint ventures is currently unknown. The lASB currently expects to issue a final standard in
2011.

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

Leases

As part of their global conversion project, the International Accounting Standards Board (IASB) and the U.S. Financial
Accounting Standards Board (“FASB”) issued in August 2010 a joint Exposure Draft 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 up to 15 years. 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 final standard in 2011.

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, operating income, cash flows from operating
activities before changes in non-cash working capital and diluted net income per common share before unusual item
attributable to Methanex Corporation shareholders. 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. We believe these
measures are useful in evaluating the operating performance and liquidity of the Company’s ongoing business. 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

This supplemental non-IFRS measure is provided to assist readers in determining our ability to generate cash from
operations. We believe this measure is useful in assessing performance and highlighting trends 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. Adjusted EBITDA differs from the most comparable IFRS measure, cash flows from operating activities,
primarily because it does not include changes in non-cash working capital, other cash payments, related to operating
activities, share-based compensation expense, other non-cash items, taxes paid, and interest and other income (expense).

The following table shows a reconciliation of cash flows from operating activities to Adjusted EBITDA:

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 Supplemental Non-IFRS Measures section on page 11 for a reconciliation to the most comparable IFRS

measure), depreciation and amortization, finance costs, finance income and other expense, 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.

The key drivers of change in our Adjusted EBITDA are average realized price, cash costs and sales volume.

The price, cash cost and volume variances included in our Adjusted EBITDA analysis are defined and calculated as follows:

PRICE

CASH COST

VOLUME

The change in 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 revenue.

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 in the current period. 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.

The change in 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 also sell methanol on a commission basis. Commission sales represent volumes marketed on a commission basis related to the

36.9% of the Atlas methanol facility in Trinidad that we do not own.

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. Nature of Operations:

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.

2. Significant accounting policies:

a) Statement of Compliance:

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).
These are the Company’s first International Financial Reporting Standards (IFRS) condensed consolidated interim
financial statements and IFRS 1, First Time Adoption of IFRS has been applied, as they are part of the period covered by
the Company’s first IFRS consolidated financial statements for the year ending December 31, 2011. 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 8 Risk Committee of the Board of
Directors on April 27, 2011.

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. 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 are set out below and 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 is provided in note 18. This note includes information on the provisions of
IFRS 1 and the exemptions that the Company elected to apply, reconciliations of equity, net income and
comprehensive income for comparative periods and equity at the date of transition, January 1, 2010.

b) Basis of presentation and consolidation:

These condensed consolidated interim financial statements include the accounts of the Company, its wholly owned
subsidiaries, less than wholly owned entities for which it has a controlling interest and its proportionate share of the
accounts of jointly controlled entities. Wholly owned subsidiaries are entities in which the Company has control,
directly or indirectly, where control is defined as the power to govern the financial and operating policies of an
enterprise so as to obtain benefits from its activities. For less than wholly owned entities for which the Company has a
controlling interest, a non-controlling interest is included in the Company’s condensed consolidated interim financial
statements and represents the non-controlling shareholders” interest in the net assets of the entity. The Company also
consolidates any special purpose entity where the substance of the relationship indicates the Company has control. All
significant intercompany transactions and balances have been eliminated. Preparation of these condensed consolidated
interim financial statements requires estimates, judgements and assumptions that affect amounts reported and disclosed
in the financial statements and related notes. The areas of estimation and judgement that management considers most
significant are property, plant and equipment (note 2(g)), site restoration costs (note 2(j)), financial instruments (note
2(0)), and income taxes (note 2(p)). Actual results could differ from those estimates.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (UNAUDITED) PAGE 21

2. Significant accounting policies (continued):

c) Reporting currency and foreign currency translation:

Functional currency is the currency of the primary economic environment in which an entity operates. The majority of
the Company’s business is transacted in US dollars and, accordingly, these condensed consolidated interim financial
statements have been measured and expressed in that currency. The Company translates foreign currency denominated
monetary items at the rates of exchange prevailing at the balance sheet dates, foreign currency denominated non-
monetary items at historic rates, and revenues and expenditures at the rates of exchange at the dates of the transactions.
Foreign exchange gains and losses are included in earnings.

d) Cash equivalents:

Cash equivalents include securities with maturities of three months or less when purchased.

e) Receivables:

The Company provides credit to its customers in the normal course of business. The Company performs ongoing credit
evaluations of its customers and maintains reserves for potential credit losses. The Company records an allowance for
doubtful accounts or writes down the receivable to estimated net realizable value if not collectible in full. Credit losses
have historically been within the range of management’s expectations.

f) Inventories:

Inventories are valued at the lower of cost and estimated net realizable value. Cost is determined by the first-in first-out
basis and includes direct purchase costs, cost of production, allocation of production overhead based on normal
operating capacity and transportation.

g) Property, plant and equipment:
Initial Recognition

Property, plant and equipment are initially recorded at cost. Cost includes expenditure that is directly attributable to
the acquisition of the asset. The cost of self-constructed assets includes the cost of materials and direct labour, any
other costs directly attributable to bringing the assets to a working condition for their intended use, the costs of
dismantling and removing the items and restoring the site on which they are located and borrowing costs on self-
constructed assets that meet certain criteria. Borrowing costs, including the impact of related cash flow hedges,
incurred during construction and commissioning are capitalized until the plant is operating in the manner intended by
management.

Subsequent costs

Routine repairs and maintenance costs are expensed as incurred. At regular intervals, the Company conducts a planned
shutdown and inspection (turnaround) at its plants to perform major maintenance and replacements of catalyst. Costs
associated with these shutdowns are capitalized and amortized over the period until the next planned turnaround.

Depreciation

Depreciation and amortization is generally provided on a straight-line basis or on a unit-of-natural gas consumption
basis, at rates calculated to amortize the cost of property, plant and equipment from the commencement of commercial
operations over their estimated useful lives to estimated residual value. The estimated useful life of the Company’s
buildings, plant installations and machinery is 5 to 25 years.

The Company reviews the depreciation and amortization rates of property, plant and equipment on an annual basis
and, if necessary, changes are accounted for prospectively.

Assets under finance lease are depreciated to their estimated residual value based on the shorter of their useful lives
and the lease term.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (UNAUDITED) PAGE 22

2. Significant accounting policies (continued):
g) Property, plant and equipment (continued):
Oil and Gas Properties

Costs incurred for oil and natural gas properties with proven reserves are capitalized to property, plant and equipment,
including the reclassification of associated exploration costs. These costs are depreciated using a unit-of-production
method, taking into consideration both estimated future costs in developing reserves and estimated proven reserves.
Proven and probable reserves for oil and natural gas properties are estimated based on independent reserve reports and
represent the estimated quantities of natural gas which are considered commercially feasible. These reserve estimates
are used to determine depreciation and to assess the carrying value of oil and natural gas properties. The accounting for
costs incurred for oil and natural gas exploration properties with unproven reserves are described in note 2(h).

Impairment

The Company reviews the carrying value of property, plant and equipment for impairment when circumstances
indicate an asset’s carrying value may not be recoverable. Examples of such events or changes in circumstances related
to our long-lived assets include, but are not restricted to: a significant adverse change in the extent or manner in which
the asset is being used or in its physical condition; a significant change in the price or availability of natural gas
feedstock required to manufacture methanol; a significant adverse change in oil and gas reserve estimates; a significant
adverse change in legal factors or in the business climate that could affect the asset’s value, including an adverse action
or assessment by a foreign government that impacts the use of the asset; or a current-period operating or cash flow loss
combined with a history of operating or cash flow losses, or a projection or forecast that demonstrates continuing losses
associated with the asset’s use. If any such indication of impairment exists, the Company makes an assessment of the
recoverable amount, by comparing the carrying value to the higher of fair value and the asset’s value in use. The
asset’s value in use is determined as the present value of the expected future cash flows less expected costs for the
disposal of the asset. An impairment write-down is recorded for the difference between the carrying amount and the
higher of fair value and the asset’s value in use. An impairment write-down recognized in prior periods for an asset ¡is
reversed if there has been a subsequent recovery in the value of the asset due to changes in events and circumstances.

h) Other assets:

Intangible assets are capitalized to other assets and amortized to depreciation and amortization expense on an
appropriate basis to charge the cost of the assets against earnings.

Financing fees related to undrawn credit facilities are capitalized to other assets and amortized to interest expense over
the term of the credit facility. Financing fees related to project debt facilities are capitalized to other assets until the
project debt is fully drawn. Once the project debt is fully drawn, these fees are reclassified to long-term debt net of
financing fees and amortized to interest expense over the repayment term on an effective interest basis.

Costs incurred for oil and natural gas exploration properties with unproven reserves are capitalized to other assets.
Upon recognition of proved reserves and internal approval for development, these costs are transferred to property,
plant and equipment and are depreciated using a unit-of-production method based on estimated proved reserves.

The Company reviews the carrying value of other assets for impairment when circumstances indicate that an asset’s
carrying value may not be recoverable.

1) Leases:

Leasing contracts are classified as either financing or operating leases. Where the contracts are classified as operating
leases, payments are charged to income in the year they are incurred. A lease is classified as a finance lease if it
transfers substantially all of the risks and rewards of ownership of the leased asset. The asset and liability associated
with a finance lease are recorded at the lower of fair value and the present value of the minimum lease payments, net
of executory costs. Lease payments are apportioned between interest expense and repayments of the liability.

METHANEX CORPORATION 2011 FIRST QUARTER REPORT
NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (UNAUDITED) PAGE 23

2. Significant accounting policies (continued):

j) Site restoration costs:

The Company recognizes a liability to dismantle and remove assets or to restore a site upon which the assets are
located. The Company estimates the fair value of the liability by determining the current market cost required to settle
the site restoration costs and adjusts for inflation through to the expected date of the expenditures and discounts this
amount back to the date when the obligation was originally incurred. As the liability is initially recorded on a
discounted basis, it is increased each period until the estimated date of settlement. The resulting expense is referred to
as accretion expense and is included in finance costs. The Company reviews asset retirement obligations and adjusts
the liability as necessary to reflect changes in the estimated future cash flows, timing, inflation and discount rates
underlying the fair value measurement. Inherent uncertainties exist in the estimate of the obligations because the
restoration activities will take place in the future and there may be changes in governmental and environmental
regulations and changes in removal technology and costs. Because of uncertainties related to estimating the cost and
timing of future site restoration activities, future costs could differ materially from the amounts estimated.

k) Employee future benefits:

The Company has non-contributory defined benefit pension plans covering certain employees and defined contribution
pension plans. The Company does not provide any significant post-retirement benefits other than pension plan benefits.
For defined benefit pension plans, the net of the present value of the defined benefit obligation and the fair value of
plan assets is recorded to the statement of financial position. The determination of the defined benefit obligation and
associated pension cost is based on certain actuarial assumptions including inflation rates, salary growth, longevity and
expected return on plan assets. The present value of the defined benefit obligation is determined by discounting
estimated future cash flows using current market bond yields which have terms to maturity approximating the terms of
the obligation. Actuarial gains and losses arising from differences between these assumptions and actual results are
recognized in other comprehensive income, and recorded in retained earnings. The cost for defined contribution
benefit plans is recognized in net income as earned by the employees.

I) Net income per common share:

The Company calculates basic net income per common share by dividing net income by the weighted average number
of common shares outstanding and calculates diluted net income per common share under the treasury stock method.
Under the treasury stock method, the weighted average number of common shares outstanding for the calculation of
diluted net income per share assumes that the total of the proceeds to be received on the exercise of dilutive stock
options is applied to repurchase common shares at the average market price for the period. Stock options are dilutive
only when the average market price of common shares during the period exceeds the exercise price of the stock
option.

m) Share-based payments:

The Company grants share-based awards as an element of compensation. Share-based awards granted by the Company
can include stock options, tandem share appreciation rights, share appreciation rights, deferred share units, restricted
share units or performance share units.

For stock options granted by the Company, the cost of the service received as consideration is measured based on an
estimate of the fair value at the date of grant. The grant-date fair value is recognized as compensation expense over the
related service period with a corresponding increase in contributed surplus. On the exercise of stock options,
consideration received, together with the compensation expense previously recorded to contributed surplus, is credited
to share capital. The Company uses the Black-Scholes option pricing model to estimate the fair value of each stock
option tranche at the date of grant.

METHANEX CORPORATION 2011 FIRST QUARTER REPORT
NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (UNAUDITED) PAGE 24

2. Significant accounting policies (continued):
m) Share-based payments (continued):

Share appreciation rights are units which grant the holder the right to receive a cash payment upon exercise for the
difference between the market price of the Company!s common shares and the exercise price which is determined at
the date of grant. Tandem share appreciation rights gives the holder the choice between exercising a regular stock
option or share appreciation right. For share appreciation rights and tandem share appreciation rights, the cost of the
service received as consideration is initially measured based on an estimate of the fair value at the date of grant. The
grant-date fair value is recognized as compensation expense over the related service period with a corresponding
increase in liabilities. For share appreciation rights and tandem share appreciation rights, the cost of the service is re-
measured at each reporting date based on an estimate of the fair value with changes in fair value recognized as
compensation expense for the proportion of the service that has been rendered at that date. The Company uses the
Black-Scholes option pricing model to estimate the fair value for share appreciation rights and tandem share
appreciation rights.

Deferred, restricted and performance share units are grants of notional common shares that are redeemable for cash
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 cost of the service received as consideration is initially measured based on the market value of the
Company’s common shares at the date of grant. The grant-date fair value is recognized as compensation expense over
the related service period with a corresponding increase in liabilities. Deferred, restricted and performance share units
are re-measured at each reporting date based on the market value of the Company’s common shares with changes in
fair value recognized as compensation expense for the proportion of the service that has been rendered at that date.

Additional information related to the stock option plan, the assumptions used in the Black-Scholes option pricing
model, tandem share appreciation rights, share appreciation rights and the deferred, restricted and performance share
units of the Company are described in note 14.

n) Revenue recognition:

Revenue is recognized based on individual contract terms when the title and risk of loss to the product transfers to the
customer, which usually occurs at the time shipment is made. Revenue is recognized at the time of delivery to the
customer’s location if the Company retains title and risk of loss during shipment. For methanol shipped on a
consignment basis, revenue is recognized when the customer consumes the methanol. For methanol sold on a
commission basis, the commission income is included in revenue when earned.

o) Financial instruments:

Financial instruments are classified into one of five categories and, depending on the category, will either be measured
at amortized cost or fair value. Held-to-maturity investments, loans and receivables and other financial liabilities are
measured at amortized cost. Financial assets and liabilities through profit and loss (held for trading category) and
available-for-sale financial assets are measured on the balance sheet at fair value. Changes in the fair value of held-for-
trading financial assets and liabilities are recognized in earnings and changes in the fair value of available-for-sale
financial assets are recorded in other comprehensive income until the investment is derecognized or impaired at which
time the amounts would be recorded in earnings. The Company classifies its cash and cash equivalents as held-for-
trading. Trade and other receivables are classified as loans and receivables. Trade, other payables and accrued
liabilities, long-term debt, net of financing costs, and other long-term liabilities are classified as other financial
liabilities.

METHANEX CORPORATION 2011 FIRST QUARTER REPORT
NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (UNAUDITED) PAGE 25

2. Significant accounting policies (continued):
0) Financial instruments (continued):

Under these standards, derivative financial instruments, including embedded derivatives, are classified as held for
trading and are recorded on the balance sheet at fair value unless exempted. The valuation of derivative financial
instruments is a critical accounting estimate due to the complex nature of these products, the degree of judgment
required to appropriately value these products and the potential impact of such valuation on the Company’s financial
statements. The Company records all changes in fair value of derivative financial instruments in earnings unless the
instruments are designated as cash flow hedges. The Company enters into and designates as cash flow hedges certain
forward exchange purchase and sales contracts to hedge foreign exchange exposure on anticipated sales. The
Company also enters into and designates as cash flow hedges certain interest rate swap contracts to hedge variable
interest rate exposure on its limited recourse debt. The Company assesses at inception and on an ongoing basis
whether the hedges are and continue to be effective in offsetting changes in the cash flows of the hedged transactions.
The effective portion of changes in the fair value of these hedging instruments is recognized in other comprehensive
income. Any gain or loss in fair value relating to the ineffective portion is recognized immediately in earnings. Until
settled, the fair value of the derivative financial instruments will fluctuate based on changes in variable interest rates.

p) Income taxes:

Income tax expense represents current tax and deferred tax. The Company records current tax based on the taxable
profits for the period which is calculated using tax rates that have been enacted or substantively enacted by the
reporting date.

Deferred income taxes are accounted for using the liability method. The liability method requires that income taxes
reflect the expected future tax consequences of temporary differences between the carrying amounts of assets and
liabilities and their tax bases. Deferred income tax assets and liabilities are determined for each temporary difference
based on currently enacted or substantially enacted tax rates that are expected to be in effect when the underlying
items of income or expense are expected to be realized. The effect of a change in tax rates or tax legislation is
recognized in the period of substantive enactment. Deferred tax assets, such as non-capital loss carryforwards, are
recognized to the extent it is probable that taxable profit will be available against which the asset can be utilized.

The Company accrues for taxes that will be incurred upon distributions from its subsidiaries when it is probable that
the earnings will be repatriated.

The determination of income taxes requires the use of judgment and estimates. If certain judgments or estimates prove
to be inaccurate, or if certain tax rates or laws change, the Company’s results of operations and financial position could
be materially impacted.

q) Provisions and contingencies:

Provisions are recognized where a legal or constructive obligation has been incurred as a result of past events, it is
probable that an outflow of resources will be required to settle the obligation, and a reliable estimate of the amount of
the obligation can be made. Provisions are measured at the present value of the expenditures expected to be required
to settle the obligation.

r) Segmented information:

The Company’s operation consists of the production and sale of methanol, which constitutes a single operating
segment.

The Company has provided funding to GeoPark Chile Limited (GeoPark) in the amount of $57 million (of which $37
million has been repaid at March 31, 2011) to support and accelerate GeoPark’s natural gas exploration and
development activities in the Fell block in southern Chile. GeoPark agreed to supply the Company with all natural gas
sourced from the Fell block under a ten-year exclusive supply arrangement. As at March 31, 2011, the outstanding
balance is $20.8 million of which $10.3 million, representing the current portion, has been recorded in trade and other
receivables.

Costs incurred for oil and natural gas exploration properties with unproven reserves are capitalized to other assets.
Upon recognition of proved reserves and internal approval for development, these costs are transferred to property,
plant and equipment.

During the three months ended March 31, 2011, the Company made repayments on its Egypt limited recourse debt
facilities of $15.6 million, and other limited recourse debt facilities of $0.6 million.

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.

The Company has a $200 million unsecured revolving bank facility provided by highly rated financial institutions that
expires in May 2012 and that 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 on any indebtedness of $10 million or more of the Company and its subsidiaries except for
the limited recourse subsidiaries is accelerated by the creditor, 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. The Egypt limited recourse debt facilities also require that certain conditions associated with
completion of plant construction and commissioning be met by no later than September 30, 2011. These conditions
include a 90-day plant reliability test and finalization of certain land title registrations and related mortgages that
require action by Egyptian governmental entities.

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 which 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 March 31, 2011, management believes the Company was in compliance with all of the covenants and default
provisions referred to above.

(ii) Compensation expense related to stock options:

For the three months ended March 31, 2011, compensation expense related to stock options included in cost
of sales and operating expenses was $0.3 million (2010 – $0.5 million). 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.

2011was $2.1 million. The Company has common shares reserved for outstanding TSARs.

(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 March 31, 2011 was
$18.0 million compared with the recorded liability of $13.6 million. The difference between the fair value and
the recorded liability of $4.4 million will be recognized over the weighted average remaining service period
of approximately 2 years. The weighted average fair value of the vested SARs and TSARs was estimated at
March 31, 2011 using the Black-Scholes option pricing model.

For the three months ended March 31, 2011, compensation expense related to SARs and TSARs included in
cost of sales and operating expenses was $5.0 million (2010 – $3.2 million).

Y Cash and cash equivalents and debt service reserve accounts are measured at fair value based on quoted prices in active markets for identical assets

and the Egypt interest rate swaps designated as cash flow hedges are measured at fair value based on industry accepted valuation models and inputs
obtained from active markets.
2 The carrying amount of the financial assets represents the maximum exposure to credit risk at the respective reporting periods.

At March 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 debt 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 September 28, 2007 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 $357 million as at March 31, 2011. The notional
amounts decrease over the expected repayment period. At March 31, 2011, these interest rate swap contracts had a
negative fair value of $35.1 million (2010 – $43.5 million) recorded in other long-term liabilities. The fair value of these
interest rate swap contracts will fluctuate until maturity and changes in their fair values have been recorded in other
comprehensive income.

17. Contingent liability:

The Board of Inland Revenue of Trinidad and Tobago (BIR) issued an assessment in 2009 against our wholly owned
subsidiary, Methanex Trinidad (Titan) Unlimited, in respect of the 2003 financial year. The assessment relates to the
deferral of tax depreciation deductions during the five year tax holiday which ended in 2005. The impact of the
amount in dispute as at March 31, 2011 is approximately $26 million in current taxes and $23 million in future taxes,
exclusive of any interest charges.

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 and accordingly, no provision has been recorded in the financial
statements.

18. Transition to International Financial Reporting Standards:

As stated in note 2, these are the Company’s first condensed consolidated interim financial statements. The accounting
policies described in note 2 have been applied in preparing the interim financial statements for the three months ended
March 31, 2011, the comparative information presented in these interim financial statements for both the three months
ended March 31, 2010 and 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, first-time adoption
of IFRS 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) for the impact to the financial statements.

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 are 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, estimated 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
using the best estimate of the historical risk-free discount rate.

Oil and Gas Properties

The Company has elected to carry forward the Canadian GAAP full cost method of accounting oil and gas asset
carrying value as of January 1, 2010 as the balance on transition to IFRS.

Reconciliations between IFRS and Canadian GAAP < page break >

IFRS 1 requires an entity to reconcile equity, comprehensive income and cash flow 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:

18. 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)

Leases:

Canadian GAAP requires an arrangement that at its inception can be fulfilled only 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, and therefore should
be accounted for as a lease, regardless of whether it takes the legal form of a lease, and therefore should be
recorded as an asset with a corresponding liability. However, Canadian GAAP has grandfathering provisions that
exempts 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 January 1, 2010 to determine the opening day IFRS impact. As at January 1, 2010
this results in an increase to property, plant and equipment of $61.1 million and other long-term liabilities of $74.2
million with a corresponding decrease to retained earnings of $13.1 million.

In comparison to Canadian GAAP, for the three months ended March 31, 2010 and the 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. As at March 31, 2010 and
December 31, 2010, this resulted in an increase to property, plant and equipment of $59.6 million and $55.1
million and other long-term liabilities of $72.9 million and $68.7 million with a corresponding decrease to
shareholders’ equity of $13.3 million and $13.5 million, respectively.

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 January 1, 2010 this
results in a decrease to retained earnings of $16.7 million, a decrease to other assets of $10.6 million and an
increase to other long-term liabilities of $6.0 million.

In comparison to Canadian GAAP for the three months ended March 31, 2010 and the year ended December 31,
2010, net earnings increased by approximately $0.8 and $1.4 million, respectively as a result of lower pension
expense due to immediate recognition to retained earnings of these actuarial losses on transition to IFRS.
Additionally, the Company’s accounting policy under IFRS is to recognize all actuarial gains and losses in other
comprehensive income and this resulted in an expense of $1.1 million for the year ended December 31, 2010. As
at March 31, 2010 and December 31, 2010, the recognition of actuarial gains and losses into retained earnings
resulted in a decrease to shareholders’ equity of $15.9 million and 16.3 million, a decrease to other assets of $10.1
million and $10.6 million and increase to other long-term liabilities of $5.8 million and $5.7 million, respectively.

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 market-based discount rate will result in a change in the
measurement of the provision. As at January 1, 2010, adjustments to the financial statements to recognize site
restorations costs on transition to IFRS are recognized as an increase to other long-term liabilities of approximately
$4.9 million and an increase to property, plant and equipment of approximately $1.3 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 at March 31, 2010 and December 31, 2010, recognition of site restoration costs
resulted in an increase to other-long-term liabilities of approximately $4.9 million and $7.7 million and an increase
to property, plant and equipment of approximately of $1.3 million and $3.6 million, with a corresponding
decrease to shareholders’ equity and no significant impact to net earnings, respectively.

e)

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 $8.3 million, $15.8 million
and $24.0 million as of January 1, 2010, March 31, 2010, and December 31, 2010, respectively. The increase to
property, plant and equipment is offset by an increase to accumulated other comprehensive income of
approximately $5.0 million, $9.5 million, and $14.4 million and an increase in non-controlling interest of
approximately $3.3 million, $6.3 million, and $9.6 million as of January 1, 2010, March 31, 2010, and December
31, 2010, respectively, with no net impact on 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 January 1, 2010, this resulted in an increase to income tax liabilities and a decrease to retained
earnings of approximately $5.4 million in comparison to Canadian GAAP. For the three months ended March 31,
2010 and the year ended December 31, 2010, this has resulted in a decrease in net earnings of $0.1 million and
$1.8 million 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 in the beginning 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 SARs and TSARs were granted for the first time in March 2010, and therefore, there is no adjustment required
to the financial statements on January 1, 2010. The difference in fair value method under IFRS compared with the
intrinsic value method under Canadian GAAP, has resulted in the decrease to net earnings of approximately $3.4
million and $4.6 million, increase to other long-term liabilities of approximately $3.8 million and $5.7 million and
corresponding decrease to shareholders” equity for the periods ended March 31, 2010 and December 31, 2010,
respectively.

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 January 1, 2010 this has resulted in a decrease to future income tax
liabilities and an increase to retained earnings of approximately $8.9 million. For the three months ended March
31, 2010 and the year ended December 31, 2010, this resulted in a decrease in net earnings of $0.2 million and
an increase to net earnings of $1.8 million, respectively.

h) 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 $137.3 million, $143.2, and $156.4 million as of January 1,
2010, March 31, 2010, and December 31, 2010, respectively.
