MANAGEMENT’S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FOR THE THREE MONTHS ENDED MARCH 31, 2015

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) should be read in conjunction with our 2014 consolidated financial statements and March 31, 2015 unaudited interim condensed consolidated financial statements, which we prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). Unless otherwise noted, all dollar amounts are expressed in U.S. dollars. The information in this discussion is provided as of April 20, 2015 unless we indicate otherwise.

Certain statements contained in this MD&A constitute forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (U.S. Exchange Act), and contain forward-looking information within the meaning of Canadian securities laws. Such forward-looking information includes, without limitation: statements related to our future growth; trends in the electronics manufacturing services (EMS) industry; our financial or operational results; the impact of acquisitions and program wins or losses on our financial results and working capital requirements; anticipated expenses, restructuring charges, capital expenditures and/or benefits; our expected tax and litigation outcomes; our cash flows, financial targets and priorities; changes in our mix of revenue by end market; our ability to diversify and grow our customer base and develop new capabilities; the effect of the global economic environment on customer demand; expected investments in our solar business and the timing and extent of expected recovery of cash advances to be made to a particular solar cell supplier; our intention to undertake a substantial issuer bid (the Offer) and the terms thereof, including the maximum dollar value of subordinate voting shares we may purchase under the Offer, the timing for launch and completion of the Offer; the sources and availability of funding for the Offer (including that we will consummate the Term Loan (as defined herein) prior to the expiration of the Offer); and the effect of the financing of the Offer, including the Term Loan, on our future operations and financial condition. Such forward-looking statements may, without limitation, be preceded by, followed by, or include words such as “believes”, “expects”, “anticipates”, “estimates”, “intends”, “plans”, “continues”, “project”, “potential”, “possible”, “contemplate”, “seek”, or similar expressions, or may employ such future or conditional verbs as “may”, “might”, “will”, “could”, “should” or “would”, or may otherwise be indicated as forward-looking statements by grammatical construction, phrasing or context. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the U.S. Private Securities Litigation Reform Act of 1995 and applicable Canadian securities laws.

Forward-looking statements are provided for the purpose of assisting readers in understanding management’s current expectations and plans relating to the future. Readers are cautioned that such information may not be appropriate for other purposes. Forward-looking statements are not guarantees of future performance and are subject to risks that could cause actual results to differ materially from conclusions, forecasts or projections expressed in such statements, including, among others, risks related to: our customers’ ability to compete and succeed in the marketplace with the services we provide and the products we manufacture; price and other competitive factors generally affecting the EMS industry; managing our operations and our working capital performance during uncertain market and economic conditions; responding to changes in demand, rapidly evolving and changing technologies, and changes in our customers’ business and outsourcing strategies, including the insourcing of programs; customer concentration and the challenges of diversifying our customer base and replacing revenue from completed or lost programs, or customer disengagements; changing commodity, material and component costs, as well as labor costs and conditions; disruptions to our operations, or those of our customers, component suppliers or logistics partners, including as a result of global or local events outside our control; retaining or expanding our business due to execution problems relating to the ramping of new programs or new offerings; the incurrence of future impairment charges; recruiting or retaining skilled personnel; current or future litigation and/or governmental actions; successfully resolving commercial and operational challenges, and improving financial results in our semiconductor business; delays in the delivery and availability of components, services and materials; non-performance by counterparties; our financial exposure to foreign currency volatility; our dependence on industries affected by rapid technological change; the variability of revenue and operating results; managing our global operations and supply chain; increasing income taxes, tax audits, and defending our tax positions or meeting the conditions of tax incentives and credits; completing any restructuring actions and integrating any acquisitions; computer viruses, malware, hacking attempts or outages that may disrupt our operations; any failure to adequately protect our intellectual property or the intellectual property of others; any U.S. government shutdown or delay in the increase of the U.S. government debt ceiling; compliance with applicable laws, regulations and social responsibility initiatives; the Offer not occurring as expected, including failure of any condition to the Offer; our inability to finance the Offer in the manner we intend (including due to any failure to consummate the Term Loan prior to the expiration of the Offer or the unavailability of sufficient funds from the net proceeds of the Term Loan, our revolving credit facility, available cash on hand and/or other capital resources to fund the Offer; any inability to obtain any required regulatory approvals or exemptive relief); the extent to which shareholders elect to tender their subordinate voting shares under the Offer; our having

1

sufficient financial resources and working capital following completion of the Offer (including to fund our currently anticipated financial obligations and to pursue desirable business opportunities); the market for our subordinate voting shares at the completion of the Offer being materially less liquid than the market that exists at the time we commence it; and the Offer launching and/or being completed later than the second quarter of 2015. Other than with respect to the Offer, the foregoing and other material risks and uncertainties are discussed in our public filings at www.sedar.com and www.sec.gov, including in this MD&A, our Annual Report on Form 20-F and subsequent reports on Form 6-K filed with or furnished to (as applicable) the U.S. Securities and Exchange Commission (SEC), and our Annual Information Form filed with the Canadian Securities Administrators.

Our forward-looking statements are based on various assumptions, many of which involve factors that are beyond our control. The material assumptions include those related to the following: production schedules from our customers, which generally range from 30 days to 90 days and can fluctuate significantly in terms of volume and mix of products or services; the timing and execution of, and investments associated with, ramping new business; the success in the marketplace of our customers’ products; the stability of general economic and market conditions, currency exchange rates, and interest rates; our pricing, the competitive environment and contract terms and conditions; supplier performance, pricing and terms; compliance by third parties with their contractual obligations, the accuracy of their representations and warranties, and the performance of their covenants; the costs and availability of components, materials, services, plant and capital equipment, labor, energy and transportation; operational and financial matters including the extent, timing and costs of replacing revenue from completed or lost programs, or customer disengagements; technological developments; overall demand improvement in the semiconductor industry; revenue growth and improved financial results in our semiconductor business; the timing and execution of any restructuring actions; our ability to diversify our customer base and develop new capabilities; the timely receipt of any required regulatory approvals and/or exemptive relief; the amendment of our revolving credit facility to provide for the Term Loan prior to the expiration of the Offer on acceptable terms; and the ability to fund the Offer in the event the Term Loan is not consummated. While management believes these assumptions to be reasonable under the current circumstances, they may prove to be inaccurate. Except as required by applicable law, we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

All forward-looking statements attributable to us are expressly qualified by these cautionary statements.

The Offer referred to in this document has not yet commenced. This document is neither an offer to purchase nor a solicitation of an offer to sell any subordinate voting shares of Celestica. The solicitation and the offer to purchase subordinate voting shares by Celestica will be made pursuant to an offer to purchase, issuer bid circular, letter of transmittal, notice of guaranteed delivery and related materials that Celestica will file with the Canadian Securities Administrators and the SEC, and that Celestica will distribute to its shareholders, copies of which will be available free of charge from Celestica, or from the following websites: www.sedar.com or www.sec.gov. These documents will contain important information about the Offer and shareholders are urged to read them carefully when they become available.

Overview

What Celestica does:

We deliver innovative supply chain solutions globally to customers in the Communications (comprised of enterprise communications and telecommunications), Consumer, Diversified (comprised of aerospace and defense, industrial, healthcare, energy, and semiconductor equipment), Servers, and Storage end markets. We believe our services and solutions create value for our customers by accelerating their time-to-market, and by providing higher quality, lower cost and reduced cycle times in our customers’ supply chains, resulting in lower total cost of ownership, greater flexibility, higher return on invested capital and improved competitive advantage for our customers in their respective markets.

Our global headquarters is located in Toronto, Canada. We operate a network of sites in various geographies with specialized end-to-end supply chain capabilities tailored to meet specific market and customer product lifecycle requirements. In an effort to drive speed, quality and flexibility for our customers, we execute our business in centers of excellence strategically located in North America, Europe and Asia. We strive to align our preferred suppliers in close proximity to these centers of excellence to increase the speed and flexibility of our supply chain, deliver higher quality products, and reduce time to market.

We offer a range of services to our customers, including design and development (such as our Joint Design and Manufacturing (JDM) offering, which is focused on developing design solutions in collaboration with customers, as well as managing aspects of the supply chain and manufacturing), engineering services, supply chain management, new product introduction, component sourcing, electronics manufacturing, assembly and test, complex mechanical assembly, systems integration, precision machining, order fulfillment, logistics and after-market repair and return services.

2

Although we supply products and services to over 100 customers, we depend upon a small number of customers for a significant portion of our revenue. In the aggregate, our top 10 customers represented 64% of revenue for the first quarter of 2015 (first quarter of 2014 — 64%; full year 2014 — 65%).

The products and services we provide serve a wide variety of applications, including: servers; networking, wireless and telecommunications equipment; storage systems; optical equipment; aerospace and defense electronics; healthcare products and applications; semiconductor equipment; and a range of industrial and green technology products, including solar panels and inverters.

In order to increase the value we deliver to our customers, we continue to make investments in people, value-added service offerings, new capabilities, capacity, technology, IT systems, software and tools. We continuously work to improve our productivity, quality, delivery performance and flexibility in our efforts to be recognized as one of the leading companies in the EMS industry.

Our current priorities include (i) profitable growth in our end markets, including improving the operational and financial performance of our semiconductor business, (ii) continuous improvement in our financial results, including revenue growth, operating margins, and return on invested capital (ROIC), and positive annual free cash flow generation, (iii) developing and building long-term trusted relationships with our customers, and (iv) investing in and strengthening our capabilities in design, engineering, process technologies, software tools and various service offerings to expand beyond our traditional areas of electronics manufacturing services. We believe that continued investments in these areas support our long-term growth strategy and will strengthen our competitive position, enhance customer satisfaction, and increase long-term shareholder value. We continue to focus on expanding our revenue base in higher-value-added services, such as design and development, engineering, supply chain management and after-market services, and to grow our business with new and existing customers in our end markets.  We are focused on expanding our business beyond our traditional end markets, which today account for a significant portion of our revenue.

Operating margin, ROIC and free cash flow are non-IFRS measures without standardized meanings and may not be comparable to similar measures presented by other companies. See “Non-IFRS measures” below for a discussion of the non-IFRS measures included herein, and a reconciliation of our non-IFRS measures to comparable IFRS measures (where a comparable IFRS measure exists).

Our financial results vary from period to period, and are impacted by factors such as changing demand for our customers’ products in various end markets, our revenue and customer mix, changes in our customers’ supply chain strategies, the size and timing of customer program wins by end market, the costs, terms and timing of ramping new business, program completions, losses or customer disengagements, the margins achieved and capital deployed for the services we provide to customers, and other factors discussed below.

Overview of business environment:

The EMS industry is highly competitive, with multiple global EMS providers competing for customers and programs. Although the industry is characterized by a large revenue base and new business opportunities, demand can be volatile from period to period, and aggressive pricing is a common business dynamic. Capacity utilization, customer mix and the types of products and services we provide are important factors affecting our financial performance. The number and location of qualified personnel, manufacturing capacity, and the mix of business through that capacity are vital considerations for EMS providers. The EMS industry is also working capital intensive. As a result, we believe that ROIC (discussed in “Non-IFRS measures” below), which is primarily affected by non-IFRS operating earnings and investments in working capital and equipment, is an important metric for measuring an EMS provider’s financial performance.

EMS companies provide a range of services to a variety of customers and end markets. Demand patterns are volatile, making customer revenue and mix, and revenue by end market difficult to forecast. Product lifecycles in the markets we serve, production lead times required by our customers, rapid shifts in technology, model obsolescence, commoditization of certain products, the emergence of new business models, shifting patterns of demand, such as the shift from traditional network infrastructures to highly virtualized and cloud-based environments as well as the proliferation of software-defined networks and software-defined storage, increased competition and pricing pressure, and the volatility of the economy, are all contributing factors. The global economy and financial markets may negatively impact end market demand and the operations of EMS providers, including Celestica. Uncertainty in the global economy may impact current and future demand for our customers’ products and services. We continue to monitor the dynamics and impacts of the global economic environment and work to manage our priorities, costs and resources to anticipate and prepare for any required changes.

External factors that could impact the EMS industry and our business include natural disasters and related disruptions, political instability, terrorism, armed conflict, labor or social unrest, criminal activity, disease or illness that affects local, national or

3

international economies, unusually adverse weather conditions, and other risks present in the jurisdictions in which we, our customers, our suppliers, and/or our logistics partners operate. These types of events could disrupt operations at one or more of our sites or those of our customers, component suppliers and/or our logistics partners. These events could lead to higher costs or supply shortages or may disrupt the delivery of components to us, or our ability to provide finished products or services to our customers, any of which could adversely affect our operating results. We carry insurance to cover damage to our sites and interruptions to our operations, including those that may occur as a result of natural disasters, such as flooding and earthquakes, or other events. Our insurance policies, however, are subject to deductibles, coverage limitations and exclusions, and may not provide adequate coverage should such events occur.

Our business is also affected by customers who may shift production between EMS providers for a number of reasons, including pricing concessions, more favorable terms and conditions, their preference or need to consolidate their supply chain capacity or the number of supply chain partners, or consolidation among customers. Customers may also choose to accelerate the amount of business they outsource, insource previously outsourced business, or change the concentration or location of their EMS suppliers to better manage their supply continuity risk. These customer decisions may impact, among other items, our revenue and margins, the need for future restructuring, the level of capital expenditures and our cash flows.

Demand is volatile across our end markets. Our revenue and margins are impacted by overall end market demand, the timing, extent and pricing of new or follow-on business, including the costs, terms and timing of ramping new business, and program completions, losses, or customer disengagements. Despite the challenging demand environment, we remain committed to making the investments we believe are required to support our long-term objectives and create shareholder value. The costs of these investments and ramping activities may be significant and could continue to negatively impact our margins in the short and medium term. Simultaneously, we intend to continue to manage our costs and resources to maximize our efficiency and productivity.

We acquired the semiconductor equipment contract manufacturing operations of Brooks Automation, Inc. (Brooks) in 2011 and D&H Manufacturing Company (D&H) in 2012 in order to expand our diversified end market offerings to include semiconductor capital equipment. Revenue from our semiconductor business for the first quarter of 2015 represented 7% (first quarter of 2014 — 6%; full year 2014 — 5%) of our total revenue. The semiconductor market has historically been cyclical and impacted by, among other things, significant and often rapid changes in product demand, changes in customer requirements for new manufacturing capacity and technology transitions, significant expenditures for capital equipment and product development, and general economic conditions. Our semiconductor business has underperformed, and continues to be, negatively impacted by volatility in customer demand, the cost of our investments, operational inefficiencies, commercial challenges associated with a particular customer, and the costs, terms, timing and challenges of ramping new sites and programs. The negative impact of these factors resulted in the reduction of our long-term cash-flow projections for our semiconductor business, and in the fourth quarter of 2014, we recorded a non-cash impairment charge of $40.8 million against the goodwill of our semiconductor business. For the first quarter of 2015, revenue from our semiconductor business grew 19% sequentially compared to the fourth quarter of 2014, primarily as a result of improved customer demand (including from the customer noted above). However, we incurred higher than expected losses in the first quarter of 2015 primarily due to ongoing operational inefficiencies and commercial challenges associated with the customer described above. We continue to work with this customer to resolve these issues, and expect to take restructuring actions to reduce the cost structure and improve the margin performance of our semiconductor business. In addition, we intend to continue our efforts to strengthen existing relationships and develop new business opportunities with the leading customers in this market. However, the negative factors affecting our semiconductor business may lead to increased volatility in our revenue and profitability and may also adversely impact our financial position and cash flows. Failure to realize future revenues at an appropriate profit margin or failure to improve the financial results of this business could result in additional impairment losses for our semiconductor business in future periods.

We are continuing our efforts to diversify our business beyond our traditional end markets. In order to support recent new program wins in our solar business and anticipated growth in global demand for solar energy, we are expanding our solar operations globally. We are making investments in the second quarter of 2015 to establish competitive solar energy manufacturing capabilities in Asia. These investments include plant and capital equipment, as well as cash advances to a solar cell supplier to help finance its working capital needs, including expansion of its manufacturing operations into Malaysia. We also recently expanded our business relationship with one of our aerospace and defense customers whereby the customer outsourced certain of its operations to us. We will manage the manufacturing and repair operations for certain product lines of this customer from its site in Ontario, Canada. As part of the agreement, we have assumed the workforce assigned to these operations and purchased the required inventory. As with any business expansion, we may encounter difficulties in ramping and executing these new programs.

Summary of Q1 2015

Our unaudited interim condensed consolidated financial statements have been prepared in accordance with IFRS as issued by the IASB and accounting policies we adopted in accordance with IFRS. These unaudited interim condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present fairly our financial position as at March 31, 2015 and the financial performance, comprehensive income and cash flows for the three months ended March 31, 2015. See “Critical Accounting Policies and Estimates” below.

The following table shows certain key operating results and financial information for the periods indicated (in millions, except per share amounts):

Revenue of $1.3 billion for the first quarter of 2015 decreased 1% from the same period of 2014. Compared to the first quarter of 2014, revenue dollars in the first quarter of 2015 from our communications end market decreased 3%, primarily due to weaker demand from certain customers, and revenue dollars from our consumer end market decreased by 44% primarily due a program completion, as we continued to de-emphasize lower-margin business in our consumer portfolio. These decreases were offset in part by a 9% increase in revenue from our storage end market and a 6% increase in revenue from our servers end market in the first quarter of 2015 compared to the same period in 2014, primarily due to new programs ramping throughout 2014 in each of these end markets, in part driven by our JDM offering. Revenue dollars from our diversified end market in the first quarter of 2015 was relatively flat compared to the same period in 2014. Communications and diversified continued to be our largest end markets for the first quarter of 2015, representing 40% and 28%, respectively, of total revenue for such period.

Gross profit of $91.4 million (7.0% of total revenue) for the first quarter of 2015 was relatively flat compared to $90.4 million (6.9% of total revenue) for the same period in 2014. SG&A for the first quarter of 2015 of $55.4 million was relatively flat compared to $55.0 million for the first quarter of 2014. Net earnings for the first quarter of 2015 of $19.7 million were $17.6 million lower compared to the same period in 2014, primarily due to an income tax benefit of $14.1 million we had recorded in the first quarter of 2014.

We believe that our balance sheet remains strong. Our cash and cash equivalents at March 31, 2015 were $569.2 million (December 31, 2014 — $565.0 million). Our non-IFRS free cash flow for the first quarter of 2015 was positive $22.0 million compared to negative $16.2 million for the first quarter of 2014, primarily due to improved working capital performance. The investments that we are making in our aerospace and defense and solar businesses will negatively impact our non-IFRS free cash flow for the second quarter of 2015 (see “Liquidity and Capital Resources — Liquidity — Cash requirements” below). At March 31, 2015, there were no amounts outstanding (December 31, 2014 — no amounts outstanding) under our revolving credit facility and we had sold $50.0 million of accounts receivable (A/R) under our A/R sales facility as of March 31, 2015 (December 31, 2014 — sold $50.0 million of A/R).

We have repurchased subordinate voting shares in the open market and otherwise for cancellation in recent years pursuant to normal course issuer bids (NCIBs), which allow us to repurchase a limited number of subordinate voting shares during a specified period, and pursuant to a substantial issuer bid completed in 2012. As part of the NCIB process, we have entered into Automatic Share Purchase Plans (ASPPs) with brokers, that allow such brokers to purchase our subordinate voting shares in the open market on our behalf for cancellation under our NCIBs (including during any applicable trading blackout periods). In addition, we have entered

5

into program share repurchases (PSRs) as part of the NCIB process, pursuant to which we make a pre-payment to a broker in consideration for the right to receive a variable number of subordinate voting shares upon such PSR’s completion. Under such PSRs, the price and number of subordinate voting shares to be repurchased by us is determined based on a discount to the volume weighted average market price of our subordinate voting shares during the term of the PSR, subject to certain terms and conditions. The subordinate voting shares repurchased under any PSR are cancelled upon completion of each PSR under the NCIB.

On September 9, 2014, the TSX accepted our notice to launch an NCIB (the 2014 NCIB), which allows us to repurchase, at our discretion, until the earlier of September 10, 2015 or the completion of purchases thereunder, up to approximately 10.3 million subordinate voting shares (representing approximately 5.8% of our total outstanding subordinate voting and multiple voting shares at the time of launch) in the open market or as otherwise permitted, subject to the normal terms and limitations of such bids. In December 2014, the TSX accepted our notice to amend the 2014 NCIB to permit the repurchase of our subordinate voting shares thereunder through one or more PSRs. In connection therewith, on January 28, 2015, we completed a $50.0 million PSR (funded in December 2014), pursuant to which we repurchased and cancelled 4.4 million subordinate voting shares at a weighted average price of $11.38 per share. During the first quarter of 2015, subsequent to the completion of the PSR, we paid $19.8 million (including transaction fees) to repurchase and cancel an additional 1.7 million subordinate voting shares under the 2014 NCIB at a weighted average price of $11.66 per share. During the first quarter of 2015, we repurchased and cancelled an aggregate of 6.1 million subordinate voting shares pursuant to our 2014 NCIB. As of March 31, 2015, we have repurchased and cancelled an aggregate of 9.0 million subordinate voting shares pursuant to this NCIB since its commencement.

On April 20, 2015, our board of directors authorized a substantial issuer bid to repurchase for cancellation up to $350 million of our subordinate voting shares (the Offer). We intend to launch and complete the Offer during the second quarter of 2015. We intend to finance the Offer using a combination of an expected new $250 million non-revolving term loan (the Term Loan), cash drawn on our existing revolving credit facility, and available cash on hand. We have received commitments from the lenders under our existing revolving credit facility to amend the facility, to add the Term Loan as a component under such facility and to extend its maturity to 2020. There can be no assurance that the amendment will be made or, if made, it will be made prior to expiration of the Offer, or at all. The Offer will not be conditioned on the Term Loan. See “Liquidity —  Cash requirements”

Other performance indicators:

In addition to the key operating results and financial information described above, management reviews the following non-IFRS measures:

Days in A/R is calculated as the average A/R for the quarter divided by the average daily revenue. Days in inventory is calculated as the average inventory for the quarter divided by the average daily cost of sales. Days in accounts payable (A/P) is calculated as the average A/P for the quarter divided by average daily cost of sales. Cash cycle days is calculated as the sum of days in A/R and days in inventory, minus the days in A/P. Inventory turns is calculated as 365 divided by the number of days in inventory. A lower number of days in A/R, days in inventory, and cash cycle days, and a higher number of days in A/P and inventory turns generally reflect improved cash management performance. These non-IFRS measures do not have comparable measures under IFRS to which we can reconcile.

6

Cash cycle days for the first quarter of 2015 of 47 days decreased one day compared to the first quarter of 2014 as a result of a 5-day reduction in days in inventory, which was offset in part by a 2-day increase in days in A/R, and a 2-day decrease in days in A/P.

Compared to the fourth quarter of 2014, cash cycle days increased 3 days in the first quarter of 2015 as a result of a 3-day increase in days in A/R and a 4-day increase in days in inventory, offset in part by a 4-day increase in days in A/P. Compared to the previous quarter, the 3-day increase in days in A/R was primarily due to reduced revenue levels in the first quarter of 2015 from the previous quarter and the timing of collections of certain receivables; the 4-day increase in inventory primarily reflected lower cost of sales in the first quarter of 2015 compared to the previous quarter and demand changes late in the first quarter of 2015 from certain customers; and the 4-day increase in days in A/P was primarily due to the timing of purchases and payments in the respective quarters.

We believe that cash cycle days (and the components thereof) and inventory turns are useful measures in providing investors with information regarding our cash management performance and are accepted measures of working capital management efficiency in our industry. These are not measures of performance under IFRS, and may not be defined and calculated in the same manner by other companies. These measures should not be considered in isolation or as an alternative to working capital as an indicator of performance.

Management reviews other non-IFRS measures including adjusted net earnings, operating margin, ROIC and free cash flow. See “Non-IFRS measures” below.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, revenue and expenses and the related disclosures of contingent assets and liabilities. Actual results could differ materially from these estimates and assumptions. We review our estimates and underlying assumptions on an ongoing basis and make revisions as determined necessary by management. Revisions are recognized in the period in which the estimates are revised and may impact future periods as well. Significant accounting policies and methods used in the preparation of our unaudited interim condensed consolidated financial statements are consistent with those described in note 2 to our 2014 audited consolidated financial statements.

Key sources of estimation uncertainty and judgment: We have applied significant estimates and assumptions in the following areas which we believe could have a significant impact on our reported results and financial position: our valuations of inventory, assets held for sale and income taxes; the amount of our restructuring charges or recoveries; the measurement of the recoverable amount of our cash generating units (CGUs) (we define a CGU as the smallest identifiable group of assets that cannot be tested individually and that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets), which includes estimating future growth, profitability and discount rates; our valuations of financial assets and liabilities, pension and non-pension post-employment benefit costs, employee stock-based compensation expense, provisions and contingencies; and the allocation of the purchase price and other valuations related to our business acquisitions. The near-term economic environment could also impact certain estimates necessary to prepare our consolidated financial statements, in particular, the recoverable amount used in our impairment testing of our non-financial assets (see note 15(b) to our 2014 audited consolidated financial statements), and the discount rates applied to our net pension and non-pension post-employment benefit assets or liabilities (see note 18 to our 2014 audited consolidated financial statements).

We have also applied significant judgment in the following areas: the determination of our CGUs and whether events or changes in circumstances during the period are indicators that a review for impairment should be conducted, and the timing of the recognition of charges and recoveries associated with our restructuring actions. During the first quarter of 2015, we did not identify any triggering event that would indicate the carrying amount of our CGUs may not be recoverable.

In May 2014, the IASB issued this standard which provides a single, principles-based five-step model for revenue recognition to be applied to all customer contracts, and requires enhanced disclosures. This standard is effective January 1, 2017 and allows early adoption. We do not intend to adopt this standard early and are currently evaluating the anticipated impact of adopting this standard on our consolidated financial statements.

IFRS 9, Financial Instruments:

In July 2014, the IASB issued this standard which replaces IAS 39, Financial Instruments: Recognition and Measurement. The standard is effective for annual periods beginning on or after January 1, 2018, and allows earlier adoption. The standard introduces a new model for the classification and measurement of financial assets, a single expected credit loss model for the measurement of the impairment of financial assets, and a new model for hedge accounting that is aligned with a company’s risk management activities. We do not intend to adopt this standard early, and are currently evaluating the anticipated impact of adopting this standard on our consolidated financial statements.

Operating Results

Our annual and quarterly operating results, including working capital performance, vary from period-to-period as a result of the level and timing of customer orders, mix of revenue, and fluctuations in materials and other costs and expenses. The level and timing of customer orders vary due to changes in demand for their products, general economic conditions, their attempts to balance their inventory, availability of components and materials, and changes in their supply chain strategies or suppliers. Our annual and quarterly operating results are specifically affected by, among other factors: our mix of customers and the types of products or services we provide; the rate at which, and the costs associated with, new program ramps; volumes and the seasonality of our business; price competition; the mix of manufacturing or service value-add; capacity utilization; manufacturing efficiency; the degree of automation used in the assembly process; the availability of components or labor; the timing of receiving components and materials; costs and inefficiencies of transferring programs between sites; program completions or losses, or customer disengagements and the timing and the margin of any replacement business; the impact of foreign exchange fluctuations; the performance of third-party providers; our ability to manage inventory, production location and equipment effectively; our ability to manage changing labor, component, energy and transportation costs effectively; fluctuations in variable compensation costs; the timing of our expenditures in anticipation of forecasted sales levels; and the timing of any acquisition and related integration costs. Our operations may also be affected by natural disasters or other local risks present in the jurisdictions in which we, our suppliers, logistics partners, and our customers operate. These events could lead to higher costs or supply shortages or may disrupt the delivery of components to us or our ability to provide finished products or services to our customers, any of which could adversely affect our operating results.

In the EMS industry, customers award new programs or shift programs to other EMS providers for a number of reasons, including changes in demand for the customers’ products, pricing benefits offered by other EMS providers, execution or quality issues, preference for consolidation or a change in their supplier base, rebalancing the concentration or location of their EMS providers, consolidation among customers, and decisions to adjust the volume of business being outsourced. Customer or program transfers between EMS providers are part of the competitive nature of our industry. Some customers use more than one EMS provider to manufacture a product and/or may have the same EMS provider support them from more than one geographic location. Customers may choose to change the allocation of demand among their EMS providers and/or may shift programs from one region to another region within an EMS provider’s global network. Customers may also decide to insource production they had previously outsourced to utilize their internal capacity or for other reasons. Our operating results for each period include the impacts associated with new program wins, follow-on business, program completions or losses, as well as acquisitions. The volume, profitability and the location of new business awards will vary from period-to-period and from program-to-program. Significant period-to-period variations can also result from the timing of new programs reaching full production or programs reaching end-of-life, the timing of follow-on or next generation programs and/or the timing of existing programs being fully or partially transferred internally or to a competitor.

Operating results expressed as a percentage of revenue:

Revenue:

Revenue of $1.3 billion for the first quarter of 2015 decreased 1% from the same period in 2014. Compared to the first quarter of 2014, revenue dollars in the first quarter of 2015 from our communications and consumer end markets decreased 3% and 44%, respectively, revenue dollars from our storage and servers end markets increased 9% and 6%, respectively, and revenue dollars from our diversified end market was relatively flat, as discussed in “Summary of Q1 2015” above and below. Communications and diversified continued to be our largest end markets for the first quarter of 2015, representing 40% and 28%, respectively, of total revenue for such period.

The following table shows revenue from the end markets we serve as a percentage of total revenue for the periods indicated:

Our product and service volumes, revenue and operating results vary from period-to-period depending on various factors, including the success in the marketplace of our customers’ products, changes in demand from our customers for the products we manufacture, the mix and complexity of the products or services we provide, the timing of receiving components and materials, the extent, timing and rate of new program wins, follow-on business, program completions or losses, the transfer of programs among our sites at our customers’ request, the costs, terms, timing and rate at which new programs are ramped, and the impact of seasonality on various end markets. We are dependent on a limited number of customers for a substantial portion of our revenue. We also expect that the pace of technological change, the frequency of customers’ transferring business among EMS competitors or customers changing the volumes they outsource, and the dynamics of the global economy will continue to impact our business from period-to-period. See “Overview” above.

In the past, we have experienced, and may in the future experience, some level of seasonality in our quarterly revenue patterns across some of the end markets we serve. We expect that the numerous factors described above that affect our period-to-period results will continue to make it difficult for us to predict the extent and impact of seasonality and other external factors on our business.

To reduce the reliance on any one customer or end market, we continue to target new customers and services, including through our efforts to expand our business in our diversified end market (see discussion below of planned investments in our solar energy capabilities and aerospace and defense expansion). Notwithstanding these expansion efforts, we remain dependent on revenue from our traditional end markets for a significant portion of our revenue.  We have experienced slower growth rates and increased pricing pressures recently, particularly in our communications end market.

Our communications end market represented 40% of total revenue for the first quarter of both 2015 and 2014. Revenue dollars from this end market in the first quarter of 2015 decreased 3% compared to the same period in 2014, primarily due to weaker demand from certain customers.

Our diversified end market represented 28% of total revenue for the first quarter of both 2015 and 2014. Revenue dollars from our diversified end market in the first quarter of 2015 was relatively flat compared to the same period in 2014.

Our storage end market represented 18% of total revenue for the first quarter of 2015, up from 16% of total revenue for the same period in 2014. Revenue dollars from our storage end market increased 9% in the first quarter of 2015 compared to the same period in 2014, primarily due to new programs we launched in 2014, in part driven by our JDM offering.

Our servers end market represented 11% of total revenue for the first quarter of 2015, compared to 10% of total revenue for the same period in 2014. In the first quarter of 2015, revenue dollars from our servers end market increased 6% compared to the same period in 2014, primarily as a result of the ramping of a new program win.

Our consumer end market represented 3% of total revenue for the first quarter of 2015, down from 6% of total revenue for the same period in 2014. Revenue dollars from our consumer end market decreased 44% in the first quarter of 2015 compared to the same period in 2014, primarily due to program completions in the second half of 2014, as we continued to de-emphasize the lower-margin business in our consumer portfolio.

For the first quarter of 2015, we had two customers that individually represented more than 10% of total revenue (first quarter of 2014 — three customers).

Whether any of our customers individually accounts for more than 10% of our total revenue in any period depends on various factors affecting our business with that customer and with other customers, including overall changes in demand for our customers’ products, the extent and timing of new program wins, follow-on business, program completions or losses, the phasing in or out of programs, the relative growth rate or decline of our business with our various customers, price competition and changes in our customers’ supplier base or supply chain strategies, and the impact of seasonality on our business.

In the aggregate, our top 10 customers represented 64% of total revenue for the first quarter of 2015 (first quarter of 2014 — 64%). We are dependent to a significant degree upon continued revenue from our largest customers. We generally enter into master supply agreements with our customers that provide the framework for our overall relationship. These agreements typically do not guarantee a particular level of business or fixed pricing. Instead, we bid on a program-by-program basis and typically receive customer purchase orders for specific quantities and timing of products. There can be no assurance that revenue from any of our major customers will continue at historical levels or will not decrease in absolute terms or as a percentage of total revenue. A significant revenue decrease or pricing pressures from these or other customers, or a loss of a major customer or program, could have a material adverse impact on our business, our operating results and our financial position.

In the EMS industry, customers may cancel contracts and volume levels can be changed or delayed. Customers may also shift business to a competitor or bring programs in-house to improve their own utilization or to adjust the concentration of their supplier base to manage supply continuity risk. We cannot assure the replacement of completed, delayed, cancelled or reduced orders with new business. In addition, we cannot assure that any of our current customers will continue to utilize our services. Order cancellations and changes or delays in production could have a material adverse impact on our results of operations and working capital performance, including requiring us to carry higher than expected levels of inventory. Order cancellations and delays could also lower our asset utilization, resulting in lower margins. Significant period-to-period changes in margins can also result if new program wins or follow-on business are more competitively priced than past programs.

We believe that delivering profitable revenue growth depends on increasing sales to existing customers for their current and future product generations and expanding the range of services we provide to these customers. We also continue to pursue new customers and acquisition opportunities to expand our end market penetration, diversify our end market mix, and to enhance and add new technologies and capabilities to our offerings.

Gross profit:

The following table is a breakdown of gross profit and gross margin (gross profit as a percentage of total revenue) for the periods indicated:

Both gross profit and gross margin for the first quarter of 2015 were relatively flat compared to the same period in 2014.

In general, in addition to fluctuations in revenue, multiple factors cause gross margin to fluctuate including, among others: volume and mix of products or services; higher/lower revenue concentration in lower gross margin products and end markets; pricing pressure; contract terms and conditions; production efficiencies; utilization of manufacturing capacity; changing material and labor costs, including variable labor costs associated with direct manufacturing employees; manufacturing and transportation costs; start-up and ramp-up activities; new product introductions; disruption in production at individual sites; cost structures at individual sites; foreign exchange volatility; and the availability of components and materials.

Our gross profit and SG&A (discussed below) are also impacted by the level of variable compensation expense we record in each period. Variable compensation expense includes expense related to our team incentive plans available to eligible employees, sales incentive plans and stock-based compensation, such as stock options, performance share units (PSUs) and restricted share units (RSUs). See “Stock-based compensation” below. The amount of variable compensation expense related to performance-based compensation varies each period depending on the level of achievement of pre-determined performance goals and financial targets.

Selling, general and administrative expenses:

SG&A for the first quarter of 2015 was $55.4 million (4.3% of total revenue), relatively flat compared to $55.0 million (4.2% of total revenue) for the first quarter of 2014.

Stock-based compensation:

Our employee stock-based compensation expense, which excludes DSU expense, varies each period, and includes mark-to-market adjustments for any awards we settle in cash and any plan amendments. The portion of our expense that relates to performance-based compensation generally varies depending on our level of achievement of pre-determined performance goals and financial targets. See the table in the section captioned “Non-IFRS Measures” below for the respective amounts of employee stock-based compensation expense recorded in each of cost of sales and SG&A for the first quarter of 2015 and 2014.

Our employee stock-based compensation expense for the first quarter of 2015 was relatively flat compared to the same period in 2014. Our employee stock-based compensation expense for the first quarter of each year typically includes the accelerated recognition of stock-based compensation expense for awards we granted to employees eligible for retirement.

Management currently intends to settle all outstanding share unit awards with subordinate voting shares purchased in the open market by a trustee or by issuing subordinate voting shares from treasury and as a result, we have accounted for these share unit awards as equity-settled awards. See “Cash requirements” below.

In the first quarter of 2015, we also recorded DSU expense of $0.5 million (first quarter of 2014 — $0.5 million).

11

Other charges (recoveries):

We have recorded the following restructuring charges for the periods indicated (in millions):

During the first quarter of 2015, we recorded restructuring charges of $0.3 million (nil for the first quarter of 2014). Our restructuring provision at March 31, 2015 was $1.7 million (December 31, 2014 — $1.9 million) comprised primarily of previously disclosed contractual lease obligations related to operations we intend to close. All cash outlays have been, and the balance is expected to be, funded from cash on hand.

As a result of our ongoing review of our operational efficiency and cost structure, we expect to take additional restructuring actions in the near term in an effort to streamline our business and improve our margin performance. These actions could include workforce reductions and site consolidations and we may incur higher operating expenses during periods of transition. We may also consider divestitures as a result of changes in the marketplace and/or our exit from less profitable, non-core or non-strategic operations. An increase in the frequency of customers transferring business to our EMS competitors, changes in the volumes they outsource, or requests to transfer their programs among our sites, may also result in our taking future restructuring actions.

In the first quarter of 2014, in connection with the settlement of class action lawsuits in which we were a plaintiff, we received recoveries of damages in the amount of $2.5 million related to certain purchases we made in prior periods.

Income taxes:

We had a net income tax expense of $7.0 million on earnings before tax of $26.7 million for the first quarter of 2015, compared to an income tax recovery of $6.6 million on earnings before tax of $30.7 million for the first quarter of 2014.

Current income taxes for the first quarter of 2015 consisted primarily of tax expense recorded in jurisdictions with current taxes payable and tax benefits arising from changes to our provisions related to certain tax uncertainties. Deferred income taxes for the first quarter of 2015 consisted primarily of net deferred income tax expense for changes in temporary differences in various jurisdictions.

Current income taxes for the first quarter of 2014 consisted primarily of tax expense recorded in jurisdictions with current taxes payable and the tax benefit of $14.1 million relating to the recognition of previously unrecognized tax incentives in Malaysia (discussed below). Deferred income taxes for the first quarter of 2014 consisted primarily of net deferred income tax expense for changes in temporary differences in various jurisdictions.

We conduct business operations in a number of countries, including countries where tax incentives have been extended to encourage foreign investment or where income tax rates are low. Our effective tax rate can vary significantly from period to period for various reasons, including the mix and volume of business in lower tax jurisdictions in Europe and Asia, and in jurisdictions with tax holidays and tax incentives that have been negotiated with the respective tax authorities which expire between 2015 and 2026 (see discussion below). Our effective tax rate can also vary as a result of restructuring charges, foreign exchange fluctuations, operating losses, certain tax exposures, the time period in which losses may be used under tax laws and whether management believes it is probable that future taxable profit will be available to allow us to recognize deferred income tax assets.

Certain countries in which we do business negotiate tax incentives to attract and retain our business. Our taxes could increase significantly if certain tax incentives from which we benefit are retracted. A retraction could occur if we fail to satisfy the conditions on which these tax incentives are based, or if they are not renewed or replaced upon expiration. Our tax expense could also increase if tax rates applicable to us in such jurisdictions are otherwise increased, or due to changes in legislation or administrative practices. Changes in our outlook in any particular country could impact our ability to meet the required conditions. Our Malaysian income tax incentives expired as of the end of 2014, including the incentive discussed below. If we are unable to obtain new Malaysian income tax incentives the periods effective as of January 1, 2015 (which are currently being negotiated), our Malaysian income tax expense may be significantly higher commencing January 1, 2015. Had we not been entitled to the Malaysian tax incentives in 2014, we estimate that our consolidated tax expense would have increased by approximately $5 million for such year.

12

During the first quarter of 2014, Malaysian investment authorities approved our request to revise certain required conditions related to income tax incentives for one of our Malaysian subsidiaries. The benefits of these tax incentives were not previously recognized, as prior to this revision we had not anticipated meeting the required conditions. As a result of this approval, we recognized an income tax benefit of $14.1 million in the first quarter of 2014 relating to years 2010 through 2013.

In certain jurisdictions, primarily in the Americas and Europe, we currently have significant net operating losses and other deductible temporary differences, which we expect will be used to reduce taxable income in these jurisdictions in future periods.

We develop our tax filing positions based upon the anticipated nature and structure of our business and the tax laws, administrative practices and judicial decisions currently in effect in the jurisdictions in which we have assets or conduct business, all of which are subject to change or differing interpretations, possibly with retroactive effect. We are subject to tax audits globally by various tax authorities of historical information which could result in additional tax expense in future periods relating to prior results. Reviews by tax authorities generally focus on, but are not limited to, the validity of our inter-company transactions, including financing and transfer pricing policies which generally involve subjective areas of taxation and a significant degree of judgment. Any such increase in our income tax expense and related interest and/or penalties could have a significant impact on our future earnings and future cash flows.

Certain of our subsidiaries provide financing, or products and services to, and may from time-to-time undertake certain significant transactions with other subsidiaries in different jurisdictions. Moreover, several jurisdictions in which we operate have tax laws with detailed transfer pricing rules which require that all transactions with non-resident related parties be priced using arm’s-length pricing principles, and that contemporaneous documentation must exist to support such pricing.

Tax authorities in Canada have taken the position that income reported by one of our Canadian subsidiaries should have been materially higher in 2001 and 2002 and materially lower in 2003 and 2004 as a result of certain inter-company transactions, and have imposed limitations on benefits associated with favorable adjustments arising from inter-company transactions and other adjustments. We have appealed this decision with the Canadian tax authorities and have sought assistance from the relevant Competent Authorities in resolving the transfer pricing matter under relevant treaty principles. We could be required to provide security up to an estimated maximum range of $20 million to $25 million Canadian dollars (approximately $16 million to $20 million at period-end exchange rates) in the form of letters of credit to the tax authorities in connection with the transfer pricing appeal, however, we do not believe that such security will be required. If the tax authorities are successful with their challenge, we estimate that the maximum net impact for additional income taxes and interest charges associated with the proposed limitations of the favorable adjustments could be approximately $41 million Canadian dollars (approximately $32 million at period-end exchange rates).

Canadian tax authorities have taken the position that certain interest amounts deducted by one of our Canadian entities in 2002 through 2004 on historical debt instruments should be re-characterized as capital losses. If the tax authorities are successful with their challenge, we estimate that the maximum net impact for additional income taxes and interest charges could be approximately $33 million Canadian dollars (approximately $26 million at period-end exchange rates). We have appealed this decision with the Canadian tax authorities and have provided the requisite security to the tax authorities, including a letter of credit in January 2014 of $5 million Canadian dollars (approximately $4 million at period-end exchange rates), in addition to amounts previously on account, in order to proceed with the appeal. We believe that our asserted position is appropriate and would be sustained upon full examination by the tax authorities and, if necessary, upon consideration by the judicial courts. Our position is supported by our Canadian legal tax advisors.

In the first quarter of 2015, we de-recognized the future benefit of certain Brazilian tax losses, which were previously recognized on the basis that these tax losses could be fully utilized to offset unrealized foreign exchange gains on inter-company debts that would become realized in the fiscal period ending on the date of dissolution of our Brazilian subsidiary. Due to the weakening of the Brazilian real against the U.S. dollar, the unrealized foreign exchange gains had diminished to the point where the tax cost to settle such inter-company debt was significantly reduced. Accordingly, our Brazilian inter-company debts were settled on April 7, 2015 triggering a tax liability of $1 million and the relevant tax costs related to the foreign exchange gains have been accrued as at March 31, 2015.

The successful pursuit of the assertions made by any taxing authority related to the above noted tax audits or others could result in our owing significant amounts of tax, interest and possibly penalties. We believe we have substantial defenses to the asserted positions and have adequately accrued for any probable potential adverse tax impact. However, there can be no assurance as to the final resolution of these claims and any resulting proceedings. If these claims and any ensuing proceedings are determined adversely to us, the amounts we may be required to pay could be material, and could be in excess of amounts currently accrued.

13

Acquisitions:

We may, at any time, be engaged in ongoing discussions with respect to possible acquisitions that could expand our service offerings, increase our penetration in various industries, establish strategic relationships with new or existing customers and/or enhance our global supply chain network. In order to enhance our competitiveness and expand our revenue base or the services we offer our customers, we may also look to grow our services or capabilities beyond our traditional areas of EMS expertise. There can be no assurance that any of these discussions will result in a definitive purchase agreement and, if they do, what the terms or timing of any such agreement would be. There can also be no assurance that an acquisition will be successfully integrated or will generate the returns we expect.

Liquidity and Capital Resources

Liquidity

The following tables show key liquidity metrics for the periods indicated (in millions):

Cash provided by (used in) operating activities:

In the first quarter of 2015, we generated $35.1 million in cash from operating activities compared to $1.8 million of cash used in operating activities in the first quarter of 2014. This increase in cash provided by operating activities was primarily due to favorable changes in working capital, reflecting lower A/R levels in the first quarter of 2015, offset in part by an unfavorable change in inventory levels due to weaker than expected customer demand in the first quarter of 2015.

Our non-IFRS free cash flow for the first quarter of 2015 increased $38.2 million compared to the same period in 2014. The increase was primarily due to the improvements in cash generated from operating activities (discussed above). See the section captioned “Non-IFRS Measures” below for a discussion of, among other items, the definition and components of non-IFRS free cash flow, as well as a reconciliation of this measure to cash provided by operating activities measured under IFRS.

Cash used in investing activities:

Our capital expenditures for the first quarter of 2015 were $12.7 million (first quarter of 2014 — $14.1 million). The capital expenditures were incurred primarily to enhance our manufacturing capabilities in various geographies and to support new customer programs. We funded these capital expenditures from cash on hand. From time-to-time, we receive cash proceeds from the sale of surplus equipment and property.

14

Cash used in financing activities:

During the first quarter of 2015, we paid $19.8 million (including transaction fees) to repurchase and cancel 1.7 million subordinate voting shares under our 2014 NCIB at a weighted average price of $11.66 per share. Details of such NCIB are described in “Summary of Q1 2015” above and note 7 to our March 31, 2015 unaudited interim condensed consolidated financial statements.

During the first quarter of 2014, we paid $12.1 million (including transaction fees) to repurchase and cancel 1.2 million subordinate voting shares under a previous NCIB that we completed in August 2014 (the 2013 NCIB). We also paid $27.1 million to a broker in February 2014 under a PSR (as part of the 2013 NCIB) for the right to receive a variable number of our subordinate voting shares upon such PSR’s completion in May 2014.

Cash requirements:

We maintain a revolving credit facility, uncommitted bank overdraft facilities, and an A/R sales program to provide short-term liquidity and to have funds available for working capital and other investments to support our strategic priorities. Our working capital requirements can vary significantly from month-to-month due to a range of business factors, including the ramping of new programs, timing of purchases, higher levels of inventory for new programs and anticipated customer demand, timing of payments and A/R collections, and customer forecasting variations. The international scope of our operations may also create working capital requirements in certain countries while other countries generate cash in excess of working capital needs. Moving cash between countries on a short-term basis to fund working capital is not always expedient due to local currency regulations, tax considerations, and other factors. To meet our working capital requirements and to provide short-term liquidity, we may draw on our revolving credit facility or sell A/R through our A/R sales program. The timing and the amounts we borrow or repay under these facilities can vary significantly from month-to-month depending upon our cash requirements. In addition, since our accounts receivable sales program is on an uncommitted basis, there can be no assurance that any participant bank will purchase the accounts receivable we wish to sell to them under this program. See “Capital Resources” below.

We had $569.2 million in cash and cash equivalents at March 31, 2015 (December 31, 2014 — $565.0 million).

We intend to finance the Offer using a combination of the net proceeds of the Term Loan (described below), cash drawn on our existing revolving credit facility, and available cash on hand. We have received commitments from the lenders under our existing revolving credit facility to amend the credit facility agreement, to add the Term Loan (in addition to the current $300.0 million limit) and extend its maturity to 2020. The interest rates and covenants are intended to remain unchanged. We anticipate that we will be able to amend our credit facility and obtain the Term Loan on acceptable terms on or prior to the expiration of the Offer. However, there can be no assurance that the Term Loan will be timely obtained on acceptable terms, or at all. The Offer will not be conditioned on the Term Loan.

We believe that using the Term Loan is a more cost-effective method of financing the Offer compared to pursuing use of the accordion feature of our existing revolving credit facility to increase its maximum limit, as the principal repayments under the Term Loan will not subject us to unused line fees. We believe that cash flow from operating activities, together with cash on hand, availability under our revolving credit facility and intra-day and overnight bank overdraft facilities, and cash from the sale of A/R, will be sufficient to fund our currently anticipated working capital needs and planned capital spending (including the commitments described elsewhere herein). We intend to repay all indebtedness incurred in connection with the Offer with cash generated from operations, and do not believe such indebtedness will have a material adverse impact on our results of operations or financial condition.

We may issue debt, convertible debt or equity securities in the future to fund operations or make acquisitions. Equity or convertible debt securities could dilute current shareholders’ positions; debt or convertible debt securities could have rights and privileges senior to those of equity holders and the terms of these debt securities could impose restrictions on our operations. The pricing of any such securities would be subject to market conditions at the time of issuance.

As at March 31, 2015, a significant portion of our cash and cash equivalents was held by foreign subsidiaries outside of Canada. Although substantially all of the cash and cash equivalents held outside of Canada can be repatriated, a significant portion may be subject to withholding taxes under current tax laws. While some of our subsidiaries are subject to local governmental restrictions on the flow of capital into and out of their jurisdictions (including in the form of cash dividends, loans or advances to us), these restrictions have not had a material impact on our ability to meet our cash obligations. We have not recognized deferred tax liabilities for cash and cash equivalents held by certain subsidiaries related to unremitted earnings that are considered indefinitely reinvested outside of Canada and that we do not intend to repatriate in the foreseeable future.

15

Our capital spending varies each period based on the timing of new business wins and forecasted sales levels. Based on our current operating plans, we anticipate capital spending for 2015 to be approximately 1.0% to 1.5% of revenue, and expect to fund these expenditures from cash on hand.

We may enter into financing arrangements for the lease of machinery and equipment. For certain leases, where the risks and rewards of ownership have substantially transferred to us, we would capitalize the leased asset and record a corresponding liability on our consolidated balance sheet. In relation to our global solar expansion plan, we entered into an agreement in April 2015 to lease manufacturing equipment valued at approximately $22 million to be used in our solar operations in Asia.

Customer or program transfers between EMS providers are part of the competitive nature of our industry. From time-to-time, we make commitments to purchase assets, primarily inventory, or fund certain costs, as part of transitioning programs from a customer or a competitor. In April 2015, one of our aerospace and defense customers outsourced certain of its operations to us. We will manage the manufacturing and repair operations for certain product lines of this customer from its site in Ontario, Canada. As part of the agreement, we have assumed the workforce assigned to these operations and purchased approximately $34 million of inventory. We believe this arrangement further strengthens our business relationship with this customer and will improve the financial performance of our diversified end market. In March 2015, we entered into a multi-year supply agreement with a solar cell supplier which includes a commitment by us to provide cash advances of up to $36 million to help finance the supplier’s working capital needs, including expansion of its manufacturing operations into Malaysia. The payment of these advances will negatively impact our non-IFRS free cash flow in the second quarter of 2015. We expect to fully recover these advances by the end of 2017.

We have granted share unit awards to employees under our stock-based compensation plans. Although we have the option to satisfy the delivery of shares upon vesting of the awards by purchasing subordinate voting shares in the open market or by settling in cash, we expect to satisfy these awards with subordinate voting shares purchased in the open market. The timing of these purchases can vary from period to period. Under one of these plans, we also have the option to satisfy the delivery of shares by issuing new subordinate voting shares from treasury, subject to certain limits.

We have funded our share repurchases under our NCIBs from cash on hand.

We provide routine indemnifications, the terms of which range in duration and often are not explicitly defined. These may include indemnifications against third-party intellectual property infringement claims and certain third-party negligence claims for property damage. We have also provided indemnifications in connection with the sale of certain businesses and real property. The maximum potential liability from these indemnifications cannot be reasonably estimated. In some cases, we have recourse against other parties to mitigate our risk of loss from these indemnifications. Historically, we have not made significant payments relating to these types of indemnifications.

Litigation and contingencies:

In the normal course of our operations, we may be subject to lawsuits, investigations and other claims, including environmental, labor, product, customer disputes and other matters. Management believes that adequate provisions have been recorded in the accounts where required. Although it is not always possible to estimate the extent of potential costs, if any, management believes that the ultimate resolution of all such pending matters will not have a material adverse impact on our financial performance, financial position or liquidity.

In 2007, securities class action lawsuits were commenced against us and our former Chief Executive and Chief Financial Officers in the United States District Court of the Southern District of New York by certain individuals, on behalf of themselves and other unnamed purchasers of our stock, claiming that they were purchasers of our stock during the period January 27, 2005 through January 30, 2007. The plaintiffs allege violations of United States federal securities laws and seek unspecified damages. They allege that during the purported period we made statements concerning our actual and anticipated future financial results that failed to disclose certain purportedly material adverse information with respect to demand and inventory in our Mexico operations and our information technology and communications divisions. In an amended complaint, the plaintiffs added one of our directors and Onex Corporation as defendants. On October 14, 2010, the District Court granted the defendants’ motions to dismiss the consolidated amended complaint in its entirety. The plaintiffs appealed to the United States Court of Appeals for the Second Circuit the dismissal of their claims against us and our former Chief Executive and Chief Financial Officers, but not as to the other defendants. In a summary order dated December 29, 2011, the Court of Appeals reversed the District Court’s dismissal of the consolidated amended complaint and remanded the case to the District Court for further proceedings. The discovery phase of the case has been completed. Defendants moved for summary judgment dismissing the case in its entirety, and plaintiffs moved for class certification and for partial summary judgment on certain elements of their claims. In an order dated February 21, 2014, the District Court denied plaintiffs’ motion for class certification because they sought to include in their proposed class persons who purchased Celestica stock in Canada. Plaintiffs renewed their motion for class certification on April 23, 2014, removing Canadian stock purchasers from

16

their proposed class in accordance with the District Court’s February 21 order. Defendants opposed plaintiffs’ renewed motion on May 5, 2014 on the grounds that the plaintiffs are not adequate class representatives. On August 20, 2014, the District Court denied our motion for summary judgment. The District Court also denied the majority of plaintiffs’ motion for partial summary judgment, but granted plaintiffs’ motion on market efficiency. The District Court also granted plaintiffs’ renewed class certification motion and certified plaintiffs’ revised class. A trial date has been set for April 20, 2015. On February 24, 2015, the parties reached an agreement in principle to settle the U.S. case. On April 17, 2015, the plaintiffs submitted the settlement to the District Court seeking preliminary approval of the settlement and of the form of notice to be issued to class members. It is anticipated that the settlement amount will be covered by our liability insurance. However, as the settlement has not yet been finalized, and remains subject to approval by the District Court, there can be no assurance that the settlement will be entered into at all, that any actual settlement or other disposition of the lawsuit will not be in excess of amounts accrued or on terms less favorable to us than the agreement in principle, or that the actual settlement or other disposition of the lawsuit will not have a material adverse impact on our financial position or liquidity. If a settlement is not consummated on terms acceptable to us, we intend to continue to vigorously defend this lawsuit.

Parallel class proceedings remain against us and our former Chief Executive and Chief Financial Officers in the Ontario Superior Court of Justice. These proceedings are not affected by the agreement in principle discussed above. On October 15, 2012, the Ontario Superior Court of Justice granted limited aspects of the defendants’ motion to strike, but dismissed the defendants’ limitation period argument. The defendants’ appeal of the limitation period issue was dismissed on February 3, 2014 when the Court of Appeal for Ontario overturned its own prior decision on the limitation period issue. On August 7, 2014, the defendants were granted leave to appeal the decision to the Supreme Court of Canada, together with two other cases that deal with the limitation period issue. The Supreme Court of Canada heard the appeal on February 9, 2015, and the decision is under reserve. A possible outcome of the Supreme Court appeal would be that the Canadian case is dismissed in its entirety. In a decision dated February 19, 2014, the Ontario Superior Court of Justice granted the plaintiffs leave to proceed with a statutory claim under the Ontario Securities Act and certified the action as a class proceeding on the claim that the defendants made misrepresentations regarding the 2005 restructuring. The court denied the plaintiffs leave and certification on the claims that the defendants did not properly report Celestica’s inventory and revenue and that Celestica’s financial statements did not comply with Canadian GAAP. The court also denied certification of the plaintiffs’ common law claims. The action is at the discovery stage and, depending on the outcome of the Supreme Court appeal, the discoveries may resume. There have been some settlement discussions among the parties to the Canadian proceedings. However, there can be no assurance that such discussions will lead to a settlement, or that any settlements or other dispositions of the Canadian lawsuit will not be in excess of amounts covered by our liability insurance policies. If the Supreme Court appeal does not result in a dismissal of the Canadian action and/or settlement on terms acceptable to us is not reached, we intend to continue to vigorously defend the lawsuit. We believe the allegations in the claim are without merit. However, there can be no assurance that the outcome of the lawsuit will be favorable to us or that it will not have a material adverse impact on our financial position or liquidity. In addition, we may incur substantial litigation expenses in defending the claim. As the matter is ongoing, we cannot predict it duration or the resources required.

See “Income Taxes” above for a description of various tax audits and positions, and contingencies associated therewith.

Capital Resources

Our main objectives in managing our capital resources are to ensure liquidity and to have funds available for working capital or other investments required to grow our business. Our capital resources consist of cash, short-term investments, access to a revolving credit facility, intraday and overnight bank overdraft facilities, an A/R sales program and capital stock. We regularly review our borrowing capacity and make adjustments, as available, for changes in economic conditions and changes in our requirements.

At March 31, 2015, we had cash and cash equivalents of $569.2 million (December 31, 2014 — $565.0 million), of which approximately 75% was cash and 25% consisted of cash equivalents. The majority of our cash and cash equivalents was denominated in U.S. dollars, and the remainder was held primarily in Euros and Chinese renminbi. Our current portfolio consists of bank deposits and certain money market funds that primarily hold U.S. government securities. A default by the U.S. government on such securities could have a material adverse effect on our results of operations and financial condition. See “Liquidity — Cash requirements” above for a discussion of the capital resources we intend to use to fund the Offer.

The majority of our cash and cash equivalents is held with financial institutions each of which had at March 31, 2015 a Standard and Poor’s short-term rating of A-1 or above. Our cash and cash equivalents are subject to intra-quarter swings, generally related to the timing of A/R collections, inventory purchases and payments, and other capital uses.

Our $300.0 million revolving credit facility has an accordion feature that allows us to increase this limit (on an uncommitted basis) by up to an additional $150.0 million upon satisfaction of certain terms and conditions. The facility includes a

17

$25.0 million swing line, subject to the overall credit limit, that provides for short-term borrowings up to a maximum of seven days. Borrowings under this facility bear interest for the period of the draw at LIBOR, Prime or Federal Funds rate plus a margin. The credit facility permits us and certain designated subsidiaries to borrow funds for general corporate purposes (including acquisitions and the Offer). We are required to comply with certain restrictive covenants in respect of the facility, including those relating to the incurrence of senior ranking indebtedness, the sale of assets, a change of control, and certain financial covenants related to indebtedness and interest coverage. Certain of our assets are pledged as security for borrowings under this facility. At March 31, 2015, there were no amounts outstanding under this facility (December 31, 2014 — no amounts outstanding), and we were in compliance with all applicable restrictive and financial covenants thereunder. This facility is scheduled to mature in October 2018. See “Liquidity — Cash requirements” above for a discussion of an anticipated amendment of the credit facility to add the Term Loan.

At March 31, 2015, we had $26.2 million (December 31, 2014 — $28.5 million) outstanding in letters of credit under our revolving credit facility. We also arrange letters of credit and surety bonds outside of our revolving credit facility. At March 31, 2015, we had $9.5 million (December 31, 2014 — $10.0 million) of such letters of credit and surety bonds outstanding.

We also have a total of $70.0 million of uncommitted bank overdraft facilities available for intraday and overnight operating requirements. There were no amounts outstanding under these overdraft facilities at March 31, 2015 or December 31, 2014.

We have an accounts receivable sales agreement to sell up to $250.0 million at any one time in accounts receivable on an uncommitted basis (subject to pre-determined limits by customer) to three third-party banks. Each of these banks had a Standard and Poor’s short-term rating of A-1 and a long-term rating of A or above at March 31, 2015. The term of this agreement has been annually extended for additional one-year periods in recent years (and is currently extendable to November 2016 under specified circumstances), but may be terminated earlier as provided in the agreement.  At March 31, 2015, we had sold $50.0 million (December 31, 2014 — $50.0 million) of A/R under this facility. Since our A/R sales program is on an uncommitted basis, there can be no assurance that any of the banks will purchase the A/R we intend to sell to them under this program.

The timing and the amounts we borrow and repay under our revolving credit and overdraft facilities, or sell under our A/R sales program, can vary significantly from month-to-month depending upon our working capital and other cash requirements.

Standard and Poor’s assigns a corporate credit rating to Celestica. This rating is not a recommendation to buy, sell or hold securities, inasmuch as it does not comment as to market price or suitability for a particular investor. This rating may be subject to revision or withdrawal at any time by the rating organization. At March 31, 2015, our Standard and Poor’s corporate credit rating was BB, with a stable outlook. A reduction in our credit rating could adversely impact our future cost of borrowing.

Our strategy on capital risk management has not changed significantly since the end of 2014. Other than the restrictive and financial covenants associated with our revolving credit facility noted above, we are not subject to any contractual or regulatory capital requirements. While some of our international operations are subject to government restrictions on the flow of capital into and out of their jurisdictions, these restrictions have not had a material impact on our operations or cash flows.

Financial instruments:

Our short-term investment objectives are to preserve principal and to maximize yields without significantly increasing risk, while at the same time not materially restricting our short-term access to cash. To achieve these objectives, we maintain a portfolio consisting of a variety of securities, including bank deposits and certain money market funds that primarily hold U.S. government securities.

The majority of our cash balances are held in U.S. dollars. We price the majority of our products in U.S. dollars and the majority of our materials costs are also denominated in U.S. dollars. However, a significant portion of our non-materials costs (including payroll, pensions, site costs and costs of locally sourced supplies and inventory) are denominated in various other currencies. As a result, we may experience foreign exchange gains or losses on translation or transactions due to currency fluctuations.

We have a foreign exchange risk management policy in place to control our hedging activities. We do not enter into speculative trades. Our current hedging activity is designed to reduce the variability of our foreign currency costs where we have local manufacturing operations. We enter into forward exchange contracts to hedge against our cash flows and significant balance sheet exposures in certain foreign currencies. Balance sheet hedges are based on our forecasts of the future position of net monetary assets or liabilities denominated in foreign currencies and, therefore, may not mitigate the full impact of any translation impacts in the future. There can be no assurance that our hedging transactions will be successful in mitigating our foreign exchange risk.

18

At March 31, 2015, we had forward exchange contracts to trade U.S. dollars in exchange for the following currencies:

These contracts, which generally extend for periods of up to 15 months, will expire by the end of the second quarter of 2016. The fair value of the outstanding contracts at March 31, 2015 was a net unrealized loss of $23.3 million (December 31, 2014 — net unrealized loss of $15.0 million). The unrealized gains or losses are a result of fluctuations in foreign exchange rates between the date the currency forward contracts were entered into and the valuation date at period end.

Financial risks:

We are exposed to a variety of market risks associated with financial instruments and otherwise.

Currency risk: Due to the global nature of our operations, we are exposed to exchange rate fluctuations on our cash receipts, cash payments and balance sheet exposures denominated in various currencies. The majority of our currency risk is driven by the operational costs incurred in local currencies by our subsidiaries. We manage our currency risk through our hedging program using forecasts of future cash flows and balance sheet exposures denominated in foreign currencies. We do not use derivative financial instruments for speculative purposes.

Interest rate risk: Borrowings under our revolving credit facility bear interest at LIBOR, Prime or Federal Funds rate plus a margin. Our borrowings under this facility expose us to interest rate risk due to fluctuations in these rates.

Credit risk: Credit risk refers to the risk that a counterparty may default on its contractual obligations resulting in a financial loss to us. We believe our credit risk of counterparty non-performance is low. To mitigate the risk of financial loss from defaults under our foreign currency forward exchange contracts, our contracts are held by counterparty financial institutions, each of which had at March 31, 2015 a Standard and Poor’s rating of A-1 or above.  Each financial institution with which we have our A/R sales program had a Standard and Poor’s short-term rating of A-1 and a long-term rating of A or above at March 31, 2015. Each financial institution from which annuities have been purchased for the defined benefit component of a pension plan had a A.M. Best or Standard and Poor’s long-term rating of A or above at March 31, 2015. We also provide unsecured credit to our customers in the normal course of business. We mitigate this credit risk by monitoring our customers’ financial condition and performing ongoing credit evaluations as appropriate. We consider credit risk in determining our allowance for doubtful accounts and we believe our allowances are adequate.

Liquidity risk: Liquidity risk is the risk that we may not have cash available to satisfy our financial obligations as they come due. The majority of our financial liabilities recorded in accounts payable, accrued and other current liabilities and provisions are due within 90 days. We believe that cash flow from operations, together with cash on hand, cash from the sale of A/R, and borrowings available under our revolving credit facility and intraday and overnight bank overdraft facilities are sufficient to fund our currently anticipated financial obligations, including funding the Offer.

Related Party Transactions

Onex Corporation (Onex) owns, directly or indirectly, all of our outstanding multiple voting shares. Accordingly, Onex has the ability to exercise significant influence over our business and affairs and generally has the power to determine all matters submitted to a vote of our shareholders where the subordinate voting shares and multiple voting shares vote together as a single class. Gerald Schwartz, the Chairman of the Board, President and Chief Executive Officer of Onex, is also one of our directors, and holds, directly or indirectly, shares representing the majority of the voting rights of Onex.

In January 2009, we entered into a Services Agreement with Onex for the services of Gerald Schwartz, as a director of Celestica. The initial term of this agreement was one year and it automatically renews for successive one-year terms unless either party provides a notice of intent not to renew. Onex receives compensation under the Services Agreement in an amount equal to $200,000 per year, payable in DSUs in equal quarterly installments in arrears.

Outstanding Share Data

As of April 16, 2015, we had 150,238,432 outstanding subordinate voting shares and 18,946,368 outstanding multiple voting shares. As of such date, we also had 2,960,174 outstanding stock options, 3,757,655 outstanding RSUs, 6,458,486 outstanding PSUs (based on a maximum potential payout), and 1,172,456 outstanding DSUs, each such option or unit entitling the holder thereof to receive one subordinate voting share (or in certain cases, cash at our option) pursuant to the terms thereof (subject to certain time or performance-based vesting conditions).

Controls and Procedures

Evaluation of disclosure controls and procedures:

Our management is responsible for establishing and maintaining a system of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the U.S. Exchange Act) designed to ensure that information we are required to disclose in the reports that we file or submit under the U.S. Exchange Act is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the U.S. Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive officer or officers and principal financial officer or officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision of and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2015. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2015, our disclosure controls and procedures are effective to meet the requirements of Rules 13a-15(e) and 15d-15(e) under the U.S. Exchange Act.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that its objectives are met. Due to inherent limitations in all such systems, no evaluation of controls can provide absolute assurance that all control issues within a company have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met.

Changes in internal control over financial reporting:

We did not identify any change in our internal control over financial reporting in connection with our evaluation, as required by paragraph (d) of U.S. Exchange Act Rule 13a-15 or 15d-15, that occurred during the quarter ended March 31, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s report on internal control over financial reporting:

Reference is made to our Management’s Report on page F-1 of our Annual Report on Form 20-F for the year ended December 31, 2014. Our auditors, KPMG LLP, an independent registered public accounting firm, have issued an audit report on our internal control over financial reporting as of December 31, 2014. This report appears on page F-2 of such Annual Report.

Unaudited Quarterly Financial Highlights (in millions, except percentages and per share amounts):

Comparability quarter-to-quarter:

The quarterly data reflects the following: the fourth quarters of 2013 and 2014 include the results of our annual impairment testing of goodwill, intangible assets and property, plant and equipment; and all quarters of 2013 set forth in the table above were impacted by our restructuring actions. The amounts attributable to these items vary from quarter-to-quarter.

First quarter 2015 compared to fourth quarter 2014:

Revenue of $1.3 billion for the first quarter of 2015 decreased 9% compared to the fourth quarter of 2014. Compared to the previous quarter, revenue dollars from our storage end market decreased 21% sequentially, primarily due to stronger than expected customer demand in this end market in the previous quarter, as well as customer demand reductions we typically experience in this end market in the first quarter of a year compared to the fourth quarter of the previous year; revenue dollars from our consumer end market decreased 13% sequentially primarily due to program completions; revenue dollars from our communications end market decreased 8% sequentially, primarily due to overall demand softness in this end market; and revenue dollars from our diversified end market decreased 3% sequentially, primarily due to softer demand in industrial, partially offset by a 19% growth in our semiconductor revenue for the first quarter of 2015. Gross margin for the first quarter of 2015 of 7.0% decreased from 7.3% for the fourth quarter of 2014, primarily as a result of lower revenue in the first quarter of 2015. Net earnings for the first quarter of 2015 of $19.7 million were $24.1 million higher compared to the net loss of $4.4 million for the previous quarter, reflecting primarily the $40.8 million non-cash impairment charge we recorded in the fourth quarter of 2014 against the goodwill of our semiconductor business, partially offset by $13.1 million higher gross profit in the fourth quarter of 2014.

First quarter 2015 actual compared to guidance:

IFRS net earnings per share for the first quarter of 2015 was $0.11 on a diluted basis. IFRS net earnings for the first quarter of 2015 included an aggregate charge of $0.07 (pre-tax) per share comprised of employee stock-based compensation expense and amortization of intangible assets (excluding computer software), which is within the guidance we provided on January 20, 2015 of an aggregate charge of between $0.04 and $0.08 for these items.

On January 20, 2015, we provided the following guidance for the first quarter of 2015:

For the first quarter of 2015, revenue of $1.3 billion and non-IFRS adjusted net earnings per share of $0.19 were both within the range of our published guidance.

22

Our guidance includes a range for adjusted net earnings per share (which is a non-IFRS measure and is defined below). We believe non-IFRS adjusted net earnings per share is an important measure for investors to understand our core operating performance and to compare our operating results with those of our competitors. A reconciliation of non-IFRS adjusted net earnings to IFRS net earnings is set forth below.

Non-IFRS measures:

Management uses adjusted net earnings and the other non-IFRS measures described herein to (i) assess operating performance and the effective use and allocation of resources, (ii) provide more meaningful period-to-period comparisons of operating results, (iii) enhance investors’ understanding of the core operating results of our business, and (iv) to set management incentive targets. We believe the non-IFRS measures we present herein are useful to investors, as they enable investors to evaluate and compare our results from operations and cash resources generated from our business in a more consistent manner (by excluding specific items that we do not consider to be reflective of our ongoing operating results) and provide an analysis of operating results using the same measures our chief operating decision makers use to measure performance. The non-IFRS financial measures that can be reconciled to IFRS measures result largely from management’s determination that the facts and circumstances surrounding the excluded charges or recoveries are not indicative of the ordinary course of the ongoing operation of our business.

We believe investors use both IFRS and non-IFRS measures to assess management’s past, current and future decisions associated with our priorities and our allocation of capital, as well as to analyze how our business operates in, or responds to, swings in economic cycles or to other events that impact our core operations.

In addition to cash cycle days (including the components thereof) and inventory turns (each described under the caption “Other Performance Indicators” above), our non-IFRS measures consist of: adjusted gross profit, adjusted gross margin (adjusted gross profit as a percentage of revenue), adjusted SG&A, adjusted SG&A as a percentage of revenue, operating earnings (adjusted EBIAT), operating margin (operating earnings as a percentage of revenue), adjusted net earnings, adjusted net earnings per share, net invested capital, ROIC, and free cash flow. Adjusted EBIAT, net invested capital, ROIC and free cash flow are further described in the tables below. In calculating these non-IFRS financial measures, management excludes the following items, as applicable: employee stock-based compensation expense, amortization of intangible assets (excluding computer software), restructuring and other charges, net of recoveries (most significantly restructuring charges), the write-down of goodwill, intangible assets and property, plant and equipment, and gains or losses related to the repurchase of shares or debt, net of tax adjustments and significant deferred tax write-offs or recoveries associated with restructuring actions or restructured sites.

Non-IFRS measures do not have any standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other companies. Non-IFRS measures are not measures of performance under IFRS and should not be considered in isolation or as a substitute for any standardized measure under IFRS. The most significant limitation to management’s use of non-IFRS financial measures is that the charges or credits excluded from the non-IFRS measures are nonetheless charges or credits that are recognized under IFRS and that have an economic impact on us. Management compensates for these limitations primarily by issuing IFRS results to show a complete picture of our performance, and reconciling non-IFRS results back to IFRS results where a comparable IFRS measure exists.

The economic substance of these exclusions and management’s rationale for excluding these from non-IFRS financial measures is provided below:

Employee stock-based compensation expense, which represents the estimated fair value of stock options, RSUs and PSUs granted to employees, is excluded because grant activities vary significantly from quarter-to-quarter in both quantity and fair value. In addition, excluding this expense allows us to better compare core operating results with those of our competitors who also generally exclude employee stock-based compensation expense from their core operating results, who may have different granting patterns and types of equity awards, and who may use different valuation assumptions than we do.

Amortization charges (excluding computer software) consist of non-cash charges against intangible assets that are impacted by the timing and magnitude of acquired businesses. Amortization of intangible assets varies among our competitors, and we believe that excluding these charges permits a better comparison of core operating results with those of our competitors who also generally exclude amortization charges.

Restructuring and other charges, net of recoveries, include costs relating to employee severance, lease terminations, site closings and consolidations, write-downs to owned property and equipment which are no longer used and are available for sale, reductions in infrastructure and acquisition-related transaction costs. We exclude restructuring and other charges, net of recoveries, because we believe that they are not directly related to ongoing operating results and do not reflect expected future operating

23

expenses after completion of these activities. We believe these exclusions permit a better comparison of our core operating results with those of our competitors who also generally exclude these charges, net of recoveries, in assessing operating performance.

Impairment charges, which consist of non-cash charges against goodwill, intangible assets and property, plant and equipment, result primarily when the carrying value of these assets exceeds their recoverable amount. Our competitors may record impairment charges at different times, and we believe that excluding these charges permits a better comparison of our core operating results with those of our competitors who also generally exclude these charges in assessing operating performance.

Gains or losses related to the repurchase of shares or debt are excluded as these gains or losses do not impact core operating performance and vary significantly among those of our competitors who also generally exclude these charges or recoveries in assessing operating performance.

Significant deferred tax write-offs or recoveries associated with restructuring actions or restructured sites are excluded as these write-offs or recoveries do not impact core operating performance and vary significantly among those of our competitors who also generally exclude these charges or recoveries in assessing operating performance.

The following table sets forth, for the periods indicated, the various non-IFRS measures discussed above, and a reconciliation of IFRS to non-IFRS measures, where a comparable IFRS measure exists (in millions, except percentages and per share amounts):

24

(1)           Management uses non-IFRS adjusted EBIAT as a measure to assess our operational performance related to our core operations. Non-IFRS adjusted EBIAT is defined as earnings before finance costs (consisting of interest and fees related to our credit facilities and accounts receivable sales program), amortization of intangible assets (excluding computer software) and income taxes. Non-IFRS adjusted EBIAT also excludes, in periods where such charges have been recorded, employee stock-based compensation expense, restructuring and other charges, net of recoveries, gains or losses related to the repurchase of shares or debt, and impairment charges.

(2)           The adjustments for taxes, as applicable, represent the tax effects on the non-IFRS adjustments and significant deferred tax write-offs or recoveries associated with restructuring actions or restructured sites that we believe do not impact our core operating performance.

(3)           Management uses non-IFRS free cash flow as a measure, in addition to IFRS cash flow from operations, to assess our operational cash flow performance. We believe non-IFRS free cash flow provides another level of transparency to our liquidity. Non-IFRS free cash flow is defined as cash provided by or used in operating activities after the purchase of property, plant and equipment (net of proceeds from sale of certain surplus equipment and property) and finance costs paid.

(4)           Management uses non-IFRS ROIC as a measure to assess the effectiveness of the invested capital we use to build products or provide services to our customers. Our non-IFRS ROIC measure includes non-IFRS operating earnings, working capital management and asset utilization. Non-IFRS ROIC is calculated by dividing non-IFRS adjusted EBIAT by average non-IFRS net invested capital. Net invested capital (calculated in the table below) is a non-IFRS measure and consists of the following IFRS measures: total assets less cash, accounts payable, accrued and other current liabilities and provisions, and income taxes payable. We use a two-point average to calculate average non-IFRS net invested capital for the quarter. There is no comparable measure under IFRS.

25

The following table sets forth, for the periods indicated, our calculation of non-IFRS ROIC % (in millions, except ROIC %):

(1)         Management uses non-IFRS ROIC as a measure to assess the effectiveness of the invested capital we use to build products or provide services to our customers. Our non-IFRS ROIC measure includes non-IFRS operating earnings, working capital management and asset utilization. Non-IFRS ROIC is calculated by dividing non-IFRS adjusted EBIAT by average non-IFRS net invested capital. Net invested capital is a non-IFRS measure and consists of the following IFRS measures: total assets less cash, accounts payable, accrued and other current liabilities and provisions, and income taxes payable. We use a two-point average to calculate average non-IFRS net invested capital for the quarter. There is no comparable measure under IFRS.
