Exhibit 99.1

CELESTICA ANNOUNCES FIRST QUARTER FINANCIAL RESULTS

TORONTO, Canada - Celestica Inc. (NYSE, TSX: CLS), a global leader in the delivery of end-to-end product lifecycle solutions, today announced financial results for the first quarter ended March 31, 2013.

First Quarter 2013 Highlights

·                  Revenue: $1.37 billion, within the range of our guidance of $1.325 to $1.425 billion (announced January 22, 2013)

·                  Revenue decreased 19%, compared to the first quarter of 2012, relatively flat after excluding revenue from Research In Motion Limited (RIM) for the first quarter of 2012

·                  IFRS EPS: $0.06 per share, compared to $0.20 per share for the first quarter of 2012

·                  Adjusted EPS (non-IFRS): $0.16 per share, within the range of our guidance of $0.11 to $0.17 per share (announced January 22, 2013)

·                  Free cash flow (non-IFRS): $13.5 million, compared to $44.4 million for the first quarter of 2012

·                  Diversified end market: 24% of total revenue, increased from 19% of total revenue for the first quarter of 2012

“Celestica delivered first quarter revenue consistent with our expectations, while achieving profitability at the high end of the guidance range driven through solid execution and disciplined cost management,” said Craig Muhlhauser, Celestica President and Chief Executive Officer. “With the overall economic outlook expected to remain challenging, we continue to focus our efforts on delivering value to our customers through strong operational performance, and on improving our financial performance through productivity improvements and effectively managing our costs and resources, while making the necessary investments to support our longer term objectives.”

First Quarter 2013 Summary

(i)            International Financial Reporting Standards (IFRS) net earnings for the first quarter of 2013 included an aggregate charge of $0.10 (pre-tax) per share for stock-based compensation, amortization of intangible assets (excluding computer software) and restructuring charges. This is within the range we provided on January 22, 2013 of a charge between $0.07 and $0.13 per share.

(ii)           Non-IFRS measures do not have any standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other companies using IFRS or other generally accepted accounting principles (GAAP). See Schedule 1 for non-IFRS definitions and a reconciliation of non-IFRS to IFRS measures (where a comparable IFRS measure exists).

End Markets by Quarter as a Percentage of Total Revenue

(i)             Our diversified end market is comprised of industrial, aerospace and defense, healthcare, solar, green technology, semiconductor equipment and other.

Restructuring Update

We completed our manufacturing services for RIM and the related transition activities in 2012. Due to the historical significance of RIM to our operations and in response to the continued challenging demand environment, in July 2012 we announced restructuring actions throughout our global network to reduce our overall cost structure and improve our margin performance. We continue to estimate the total restructuring charges to complete our planned actions to be in the range of $55 million to $65 million. Of this estimated amount, we recorded $44.0 million in 2012 and $7.3 million in the first quarter of 2013. We expect to complete the remaining actions by the end of 2013.

Second Quarter 2013 Outlook

For the second quarter ending June 30, 2013, we anticipate revenue to be in the range of $1.375 to $1.475 billion, and adjusted net earnings per share to be in the range of $0.13 to $0.19. We expect a negative $0.05 to $0.10 per share (pre-tax) aggregate impact on an IFRS basis for the following items: stock-based compensation, amortization of intangible assets (excluding computer software) and restructuring charges.

Forward-looking statements are not guarantees of future performance. Readers should understand that the following important factors, among others, may affect our future results and could cause those results to differ materially from those expressed in such forward-looking statements: our dependence on a limited number of customers and on our customers’ ability to compete and succeed in the marketplace with the products we manufacture; the effects of price and other competitive factors generally affecting the electronics manufacturing services (EMS) industry; the challenges of effectively managing our operations and our working capital performance during uncertain economic conditions, including responding to rapid changes in demand and changes in our customers’ outsourcing strategies, including the insourcing of programs; the challenges of diversifying our customer base, including the extent, timing, and costs of replacing revenue from lost programs or customer disengagements; the challenges of managing 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 our logistics partners, resulting from local events, including natural disasters, political instability, terrorism, armed conflict, labor or social unrest, criminal activity, disease or illness that affects local, national or international economies, and other risks present in the jurisdictions in which we, our customers and our suppliers operate; our inability to retain or expand our business due to execution problems relating to the ramping of new programs; delays in the delivery and availability of components, services and materials used in our manufacturing process; the risk of non-performance by counterparties; the challenges of mitigating our financial exposure to foreign currency volatility; our dependence on industries affected by rapid technological change; variability of operating results; our ability to successfully manage our global operations and supply chain; increasing income taxes, increased levels and scrutiny of tax audits globally, and the challenges of successfully defending our tax positions or meeting the conditions of tax incentives and credits; our ability to successfully implement and complete our restructuring plans and integrate our acquisitions in a timely manner; our ability to define and successfully implement an information technology strategy and countermeasures to mitigate the risk of computer viruses, malware, hacking attempts or outages that may disrupt our operations; and the impact of our compliance with applicable laws, regulations and social responsibility initiatives. These and other risks and uncertainties, as well as other information related to Celestica, are discussed herein and in our various public filings at www.sedar.com and www.sec.gov, including our Annual Report on Form 20-F and subsequent reports on Form 6-K filed with the U.S. Securities and Exchange Commission and our Annual Information Form filed with the Canadian Securities Administrators. Forward-looking statements are provided for the purpose of providing information about management’s current expectations and plans relating to the future.  Readers are cautioned that such information may not be appropriate for other purposes. 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.

Our revenue, earnings and other financial guidance, as contained in this press release, is based on various assumptions which management believes are reasonable under the current circumstances, but may prove to be inaccurate, and many of which involve factors that are beyond the control of the company. The material assumptions may include the following: production schedules from our customers, which generally range from 30 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; general economic and market conditions; currency exchange rates; pricing, the competitive environment and contract terms and conditions; supplier performance, pricing and terms; compliance by all third parties with their contractual obligations, the accuracy of their representations and warranties, and the performance of their covenants; components, materials, services, plant and capital equipment, labor, energy and transportation costs and availability; operational and financial matters; technological developments; the timing and execution of our restructuring actions; and our ability to diversify our customer base and develop new capabilities. These assumptions and estimates are based on management’s current views with respect to current plans and events, and are and will be subject to the risks and uncertainties referred to above. It is Celestica’s policy that our guidance is effective as of the date given, and, if required to be updated, will be communicated through a public announcement.

Schedule 1

Supplementary Non-IFRS Measures

Our non-IFRS measures include gross profit, gross margin (gross profit as a percentage of revenue), selling, general and administrative expenses (SG&A), SG&A as a percentage of revenue, operating earnings (EBIAT), operating margin (EBIAT as a percentage of revenue), adjusted net earnings, adjusted net earnings per share, return on invested capital (ROIC), free cash flow, cash cycle days and inventory turns. In calculating these non-IFRS financial measures, management excludes the following items, as applicable: stock-based compensation, 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.

These non-IFRS measures do not have any standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other companies using IFRS, or our North American competitors who report under U.S. GAAP and use non-U.S. GAAP measures to describe similar operating metrics. 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 the company. Management compensates for these limitations primarily by issuing IFRS results to show a complete picture of the company’s performance, and reconciling non-IFRS results back to IFRS 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:

Stock-based compensation, which represents the estimated fair value of stock options, restricted share units and performance share units 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 stock-based compensation 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, including those competitors who use U.S. GAAP and non-U.S. GAAP measures to present similar metrics.

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 intangibles varies among 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, facility closings and consolidations, write-downs of 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 they are not directly related to ongoing operating results and do not reflect expected future operating expenses after completion of these activities.  We believe this exclusion permits a better comparison of our core operating results with those of our competitors who also generally exclude these charges 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 fair value. Our competitors may record impairment charges at different times and 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 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, a reconciliation of IFRS to non-IFRS measures (in millions, except per share amounts):

(1)          EBIAT is defined as earnings before interest, amortization of intangible assets (excluding computer software) and income taxes.  EBIAT also excludes stock-based compensation, 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 that do not impact our core operating performance.

(3)          Management uses free cash flow as a measure, in addition to cash flow from operations, to assess operational cash flow performance. We believe free cash flow provides another level of transparency to our liquidity as it represents cash generated from 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 ROIC as a measure to assess the effectiveness of the invested capital we use to build products or provide services to our customers. Our ROIC measure includes operating margin, working capital management and asset utilization. ROIC is calculated by dividing EBIAT by average net invested capital. Net invested capital consists of 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 net invested capital for the quarter. There is no comparable measure under IFRS.

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

GUIDANCE SUMMARY

(1)  We expect a negative $0.05 to $0.10 per share (diluted) pre-tax aggregate impact on an IFRS basis for the following recurring items: stock-based compensation, amortization of intangible assets (excluding computer software) and restructuring charges.

Celestica delivers innovative supply chain solutions globally to customers in the Communications (comprised of enterprise communications and telecommunications), Consumer, Diversified (comprised of industrial, aerospace and defense, healthcare, solar, green technology, semiconductor equipment and other), and Enterprise Computing (comprised of servers and storage) end markets. Our product lifecycle offerings include a range of services to our customers including design, 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.                                      BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES

Statement of compliance:

These unaudited interim condensed consolidated financial statements have been prepared in accordance with International Accounting Standard (IAS) 34, Interim Financial Reporting as issued by the International Accounting Standards Board (IASB) and accounting policies we have adopted in accordance with International Financial Reporting Standards (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, 2013 and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2013.

The unaudited interim condensed consolidated financial statements were authorized for issuance by our board of directors on April 22, 2013.

Functional and presentation currency:

These unaudited interim condensed consolidated financial statements are presented in U.S. dollars, which is also our functional currency. All financial information is presented in millions of U.S. dollars (except per share amounts).

Use of estimates and judgments:

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.  Revisions are recognized in the period in which the estimates are revised and may impact future periods as well.

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 restructuring charges or recoveries;  the measurement of the recoverable amount of our cash generating units (CGU); our valuations of financial assets and liabilities, pension and non-pension post-employment benefit costs, stock-based compensation, provisions and contingencies; and the allocation of our purchase price and other valuations we use in 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, and the discount rates applied to our net pension and non-pension post-employment benefit assets or liabilities.

We have applied significant judgment to 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 associated with restructuring plans.

CELESTICA INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions of U.S. dollars, except per share amounts)

(unaudited)

These unaudited interim condensed consolidated financial statements are based upon accounting policies and estimates consistent with those used and described in note 2 of our 2012 annual consolidated financial statements, except for the recently adopted accounting pronouncements discussed below.

Recently adopted accounting pronouncements:

Effective January 1, 2013, we adopted the following new or amended accounting standards as issued by the IASB: IFRS 10 (Consolidated Financial Statements), IFRS 11 (Joint Arrangements), IFRS 12 (Disclosure of Interests in Other Entities) and IFRS 13 (Fair Value Measurement), and the amendments to IAS 1 (Presentation of Financial Statements) and IFRS 7 (Financial Instruments - Disclosures). The adoption of these standards and amendments did not have a material impact on our unaudited interim condensed consolidated financial statements.

Effective January 1, 2013, we adopted the amendment to IAS 19 (Employee Benefits) issued by the IASB, which requires a retroactive restatement of prior periods. As of January 1, 2012, we had $6.7 of unrecognized past service credits that we had been amortizing to operations on a straight-line basis over the vesting period. Upon retroactive adoption of this amendment, we recognized these past service credits on our balance sheet and decreased our post-employment benefit obligations and our deficit by $6.7 as of January 1, 2012 (December 31, 2012 — $6.0). The impact on our net earnings for 2012 and for the first quarter of 2013 was not significant. Under this amendment, we continue to recognize actuarial gains or losses on plan assets or obligations through other comprehensive income and to reclassify the amounts to deficit.

3.                                      RECENT ACQUISITION

In September 2012, we completed the acquisition of D&H Manufacturing Company (D&H), a leading manufacturer of precision machined components and assemblies based in California, U.S.A. D&H provides manufacturing and engineering services, coupled with dedicated capacity and equipment for prototype and quick-turn support, to some of the world’s leading semiconductor capital equipment manufacturers. The final purchase price was $71.0, net of cash acquired, which we financed from cash on hand. On the acquisition date, we recorded $26.4 in goodwill and $24.0 in customer intangible assets. We expensed $0.9 in acquisition-related transaction costs during 2012 through other charges.

4.                                      SEGMENT AND CUSTOMER REPORTING

End markets:

The following table indicates revenue by end market as a percentage of total revenue. Our revenue fluctuates from period-to-period depending on numerous factors, including but not limited to: seasonality of business, the mix and complexity of the products or services we provide, the extent, timing and rate of new program wins, follow-on business or program losses, the phasing in or out of programs, the success in the marketplace of our customers’ products, and changes in customer demand. We expect that the pace of technological change, the frequency of customers transferring business among EMS competitors and the level of outsourcing by customers (including decisions on insourcing), and the dynamics of the global economy will also continue to impact our business from period-to-period.

Customers:

For the first quarter of 2013, we had two customers that individually represented more than 10% of total revenue (first quarter of 2012 — one customer). We completed our manufacturing services for Research In Motion Limited (RIM) and the related transition activities by the end of 2012. Our revenue from RIM in the first quarter of 2013 was zero (first quarter of 2012 — 19% of total revenue; fourth quarter of 2012 — minimal). For the full year 2012, RIM accounted for 12% of total revenue.

5.                                      ACCOUNTS RECEIVABLE

We have an agreement to sell up to $375.0 in accounts receivable on an uncommitted basis (subject to pre-determined limits by customer) to two third-party banks. Both banks had a Standard and Poor’s long-term rating of A or above and short-term rating of A-1 at March 31, 2013. This agreement can be terminated at any time by the banks or us. At March 31, 2013, we had sold $60.0 of accounts receivable under this facility (December 31, 2012 — $50.0). The accounts receivable sold are removed from our consolidated balance sheet and reflected as cash provided by operating activities in our consolidated statement of cash flows. Upon sale, we assign the rights to the accounts receivable to the banks. We continue to collect cash from our customers and remit the cash to the banks when collected. We pay interest and fees which we record through finance costs in our consolidated statement of operations.

6.                                      INVENTORIES

We record our inventory provisions and valuation recoveries through cost of sales. We record inventory provisions to reflect changes in the value of our inventory to net realizable value, and valuation recoveries primarily to reflect realized gains on the disposition of inventory previously written down. We recorded net inventory provisions of $3.3 for the first quarter of 2013 (first quarter of 2012 — $3.5). We regularly review our estimates and assumptions used to value our inventory through analysis of historical performance.

7.                                      CREDIT FACILITIES

We have a $400.0 revolving credit facility that matures in January 2015. We are required to comply with certain restrictive covenants including those relating to debt incurrence, the sale of assets, a change of control and certain financial covenants related to indebtedness, interest coverage and liquidity. We pledged certain assets as security for borrowings under this facility. The facility includes a $25.0 swing line that provides for short-term borrowings up to a maximum of seven days. The credit facility permits us and certain designated subsidiaries to borrow funds for general corporate purposes (including acquisitions).

Borrowings under this facility bear interest at LIBOR or Prime rate for the period of the draw plus a margin. These borrowings have historically been outstanding for fewer than 90 days. In December 2012, we completed a substantial issuer bid (SIB) to repurchase for cancellation $175.0 of our subordinate voting shares which we funded in part through this credit facility. See note 8. At March 31, 2013, we had $20.0 outstanding under this facility (December 31, 2012 — $55.0 outstanding), and we were in compliance with all covenants. Commitment fees paid in the first quarter of 2013 were $0.5. At March 31, 2013, we had issued $30.5 (December 31, 2012 — $31.1) in letters of credit under this facility.

We also have uncommitted bank overdraft facilities available for intraday and overnight operating requirements which total $70.0 at March 31, 2013. There were no amounts outstanding under these overdraft facilities at March 31, 2013 (December 31, 2012— no amounts outstanding).

The amounts we borrow and repay under these facilities can vary significantly from month-to-month depending upon our working capital and other cash requirements.

8.                                      CAPITAL STOCK

In the fourth quarter of 2012, we completed a SIB and repurchased for cancellation 22.4 million subordinate voting shares for $175.0. We funded the share repurchases using a combination of cash on hand and cash drawn from our revolving credit facility. See note 7.

(unaudited)

Our Normal Course Issuer Bid (NCIB) that allowed us to repurchase up to 16.2 million subordinate voting shares in the open market expired in February 2013. During the first quarter of 2013, we did not repurchase any subordinate voting shares for cancellation under the NCIB. During the first quarter of 2012, we had paid $56.4 to repurchase for cancellation 6.0 million subordinate voting shares under this NCIB (full year 2012 — paid $113.8 for 13.3 million shares).

We grant share unit awards to employees under our equity-based compensation plans. We have the option to satisfy the delivery of shares upon vesting of the awards by issuing new subordinate voting shares from treasury, purchasing subordinate voting shares in the open market, or by settling in cash. From time-to-time, we pay cash for the purchase by a trustee of subordinate voting shares in the open market to satisfy the delivery of shares upon vesting of awards. For accounting purposes, we classify these shares as treasury stock until they are delivered pursuant to the plans. In addition to the $17.9 paid in the fourth quarter of 2012, we paid $0.4 in January 2013 for a trustee to complete an Automated Share Purchase Plan (ASPP), pursuant to which 2.2 million subordinate voting shares were purchased in the open market for delivery under our equity-based compensation plans. During the first quarter of 2012, we paid $3.0 for the trustee’s purchase of subordinate voting shares in the open market. At March 31, 2013, the trustee held 0.3 million subordinate voting shares with a value of $2.2. At December 31, 2012, the trustee held 0.8 million subordinate voting shares with a value of $6.4, and $11.9 in cash, representing the estimated amount of cash required to complete the ASPP.

The following table outlines the activities for equity-based awards for the three months ended March 31, 2013:

(i)                                   During the first quarter of 2013, we granted 2.1 million performance share units (PSUs), of which 60% vest based on the achievement of a market performance condition tied to Total Shareholder Return (TSR) and 40% vest based on a non-market performance condition. See note 2(n) of our 2012 annual consolidated financial statements for a description of TSR. We estimated the grant date fair value of the TSR-based portion of PSUs using a Monte Carlo simulation model. The fair value of the balance of the PSUs is based on the market value of our subordinate voting shares at the time of grant. We expect to settle these awards with subordinate voting shares purchased in the open market. The number of PSUs that will actually vest will vary from 0% to 200% depending on the achievement of pre-determined performance goals and financial targets. The number of PSUs above represents the maximum payout at 200%. During the first quarter of 2012, we granted 2.4 million PSUs, all of which vest based on the achievement of a market performance condition tied to TSR.

(ii)                                During the first quarter of 2013, we received cash proceeds of $2.7 (first quarter of 2012 — $2.8) relating to the exercise of stock options.

(iii)                             We estimated the grant date fair value of options using the Black-Scholes option pricing model. The estimates we use in the pricing model include the following: expected price volatility of our subordinate voting shares, weighted average expected life of the option, expected dividends, and the risk-free interest rate.

For the first quarter of 2013, stock-based compensation expense was $9.5 (first quarter of 2012 — $10.7). The amount of our stock-based compensation expense varies each period. The portion of our expense that relates to performance-based compensation generally varies depending on the level of achievement of pre-determined performance goals and financial targets.
