·                  Revenue dollars from our Communications end market increased 14% compared to the second quarter of 2016, and represented 44% of total revenue, compared to 41% of total revenue for the second quarter of 2016

·                  Revenue dollars from our Advanced Technology Solutions* end market decreased 3% compared to the second quarter of 2016, and represented 31% of total revenue, compared to 33% of total revenue for the second quarter of 2016

·                  IFRS EPS: $0.24 per share, compared to $0.25 per share for the second quarter of 2016

·                  Adjusted EPS (non-IFRS): $0.32 per share, at the mid-point of our previously provided guidance range of $0.29 to $0.35 per share, compared to $0.29 per share for the second quarter of 2016

“Celestica delivered strong revenue in the second quarter representing another consecutive quarter of year-over-year revenue growth,” said Rob Mionis, Celestica’s President and Chief Executive Officer.

“I am pleased with the progress we are making against our strategy to create long-term value.  We continue to evolve and diversify our customer and product portfolios across our business. As we enter the second half of the year, we intend to continue to invest in ramping new programs and in higher margin services such as our Joint Design and Manufacturing offering to help deliver strategic value to our customers.”

*  Our Advanced Technology Solutions (ATS) end market is comprised of our former Diversified and Consumer end markets (see below).

Second Quarter Summary

(i)      International Financial Reporting Standards (IFRS) earnings per share (EPS) for the second quarter of 2017 included an aggregate charge of $0.09 (pre-tax) per share for employee stock-based compensation expense, amortization of intangible assets (excluding computer software) and restructuring charges. This aggregate charge is within the range of between $0.06 to $0.12 per share that we provided on April 20, 2017 for these items (see the tables in Schedule 1 attached hereto for per-item charges).

IFRS EPS for the second quarter of 2017 was favorably impacted by a $0.03 per share deferred income tax benefit related to the write-downs and impairments of our solar assets recorded in the current and prior quarters. In connection with our exit from the solar panel manufacturing business, we withdrew one of our tax incentives in Thailand during the second quarter of 2017. The withdrawal of this incentive allows us to apply future tax losses arising from the ultimate disposition of our solar assets against other fully taxable profits in Thailand, resulting in the deferred income tax benefit.

(ii)     IFRS EPS and adjusted EPS (non-IFRS) for the second quarter of 2016 were negatively impacted by a $0.02 per share income tax expense related to taxable foreign exchange resulting from the weakening of the Malaysian ringgit and Chinese renminbi, compared to the U.S. dollar.

Non-IFRS measures do not have any standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other public companies that use IFRS or other generally accepted accounting principles (GAAP). See “Non-IFRS Supplementary Information” below for information on our rationale for the use of non-IFRS measures, and Schedule 1 for, among other items, non-IFRS measures included in this press release, as well as their definitions, uses, and a reconciliation of non-IFRS to IFRS measures.

End Markets by Quarter as a Percentage of Total Revenue

As noted in the prior quarter, as part of our recent organizational initiatives, we have aligned our end markets into two customer focused areas: Advanced Technology Solutions (ATS) and Connectivity & Cloud Solutions (CCS). ATS consists of our former Diversified and Consumer end markets, and CCS consists of our Communications and Enterprise end markets. Due to the decreasing size of our Consumer end market, we combined it with our previously-reported Diversified end market to form our ATS end market commencing in the first quarter of 2017. As a result, ATS consists of our aerospace and defense, industrial, smart energy, healthcare, semiconductor equipment and consumer. Also commencing in the first quarter of 2017, due to the converging technologies of our Storage and Servers end markets, we combined them into a single “Enterprise” end market for reporting purposes. All period percentages herein reflect these changes.

2

Third Quarter 2017 Outlook

For the quarter ending September 30, 2017, we anticipate revenue to be in the range of $1.5 billion to $1.6 billion, non-IFRS operating margin to be 3.7% at the mid-point of our expectations, and non-IFRS adjusted earnings per share to be in the range of $0.28 to $0.34. We expect a negative $0.06 to $0.12 per share (pre-tax) aggregate impact on net earnings on an IFRS basis for employee stock-based compensation expense, amortization of intangible assets (excluding computer software) and restructuring charges. We cannot predict changes in currency exchange rates, the impact of such changes on our operating results, or the degree to which we will be able to manage such impacts.

We do not provide reconciliations for forward-looking non-IFRS financial measures, as we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing or amount of various events that have not yet occurred, are out of our control and/or cannot be reasonably predicted, and that would impact the most directly comparable forward-looking IFRS financial measure. For these same reasons, we are unable to address the probable significance of the unavailable information. Forward-looking non-IFRS financial measures provided without the most directly comparable IFRS financial measures may vary materially from the corresponding IFRS financial measures.

Second Quarter 2017 Webcast

Management will host its second quarter 2017 results conference call today at 5:00 p.m. Eastern Daylight Time. The webcast can be accessed at www.celestica.com.

Board Member Resignation

Joseph M. Natale, who was recently appointed as President and CEO of Rogers Communications, has resigned from Celestica’s Board effective July 26, 2017.

Non-IFRS Supplementary Information

In addition to disclosing detailed operating results in accordance with IFRS, Celestica provides supplementary non-IFRS measures to consider in evaluating the company’s operating performance. Management uses adjusted net earnings and other non-IFRS measures to assess operating performance and the effective use and allocation of resources; to provide more meaningful period-to-period comparisons of operating results; to enhance investors’ understanding of the core operating results of Celestica’s business; and to set management incentive targets. 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. See Schedule 1 - Supplementary Non-IFRS Measures for, among other items, non-IFRS measures provided herein, non-IFRS definitions, and a reconciliation of non-IFRS to IFRS measures.

Our revenue, earnings and other financial guidance, as contained in this press release, is based on various assumptions, many of which involve factors that are beyond our control. Our 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 pace of change in our traditional end markets and our ability to retain programs and customers; 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; the timing and extent of recoveries from the sale of inventory and manufacturing equipment related to our exit from the solar panel manufacturing business and our ability to recover accounts receivable outstanding from our solar customers, including a former solar supplier; the timing, execution and effect of restructuring actions; our having sufficient financial resources and working capital to fund currently anticipated financial obligations and to pursue desirable business opportunities; and our ability to diversify our customer base and develop new capabilities. While management believes these assumptions to be reasonable under the current circumstances, they may prove to be inaccurate. Forward-looking statements speak only as of the date on which they are made, and 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, except as required by applicable law.

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

Schedule 1

Supplementary Non-IFRS Measures

Our non-IFRS measures herein include adjusted gross profit, adjusted gross margin (adjusted gross profit as a percentage of revenue), adjusted selling, general and administrative expenses (SG&A), adjusted SG&A as a percentage of revenue, operating earnings (adjusted EBIAT), operating margin (adjusted EBIAT as a percentage of revenue), adjusted net earnings, adjusted earnings per share, adjusted return on invested capital (adjusted ROIC), free cash flow and adjusted effective tax rate. Adjusted EBIAT, adjusted ROIC, free cash flow and adjusted effective tax rate are further described in the tables below. In calculating these non-IFRS financial measures, management excludes the following items, where applicable: employee stock-based compensation expense, amortization of intangible assets (excluding computer software), restructuring and other charges, net of recoveries, other solar charges (described below), the write-down of goodwill, intangible assets and property, plant and equipment, all net of the associated tax adjustments (which are set forth in the table below), and deferred tax write-offs/costs or recoveries associated with restructuring actions or restructured sites.

We believe the non-IFRS measures we present herein are useful, 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. In addition, management believes that the use of a non-IFRS adjusted effective tax rate provides improved insight into the tax effects of our ongoing business operations, and is useful to management and investors for historical comparisons and forecasting. These non-IFRS financial 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.

Non-IFRS measures do not have any standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other public companies that use IFRS, or 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 results.

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

Employee stock-based compensation expense, 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 employee stock-based compensation expense in assessing operating performance, 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 report under U.S. GAAP and use 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 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 in assessing operating performance.

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

6

Other solar charges consist of non-cash charges to further write down our remaining solar related assets. These additional charges were identified after our decision to exit the solar panel manufacturing business, and consist of the further write down of the carrying value of our remaining solar panel inventory and the write-down of solar accounts receivable (A/R) (primarily as a result of a solar customer’s bankruptcy) to estimated recoverable amounts, recorded through cost of sales and SG&A expenses, respectively. Both of these impairment charges, which were identified during the wind down phase of our solar operations, are excluded as they pertain to a business we are exiting, and we therefore believe they are no longer directly related to our ongoing core operating results. Although we recorded significant impairment charges to write down our solar panel inventory in the third quarter of 2016, those charges were not excluded in the determination of our non-IFRS financial measures for such period, as we were then still engaged in the solar panel manufacturing business.  In connection with this wind down, we also recorded non-cash impairment charges to further write down the carrying value of our solar panel manufacturing equipment currently held for sale to its estimated fair value (at period-end) less costs to sell, which we recorded through other charges. See note 11 of our unaudited interim condensed consolidated financial statements for the quarter ended June 30, 2017.

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.

Deferred tax write-offs/costs or recoveries associated with restructuring actions or restructured sites are excluded, as we believe that these write-offs/costs or recoveries do not reflect 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 (in millions, except percentages and per share amounts):

7

(1)     Management uses non-IFRS operating earnings (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 facility, our accounts receivable sales program and a customer’s supplier financing 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, including acquisition-related

8

transaction costs (net of recoveries), impairment charges, other solar charges, and refund interest income with respect to amounts previously held on account with Canadian tax authorities.

(2)     The adjustments for taxes, as applicable, represent the tax effects on our non-IFRS adjustments and tax write-offs or recoveries related to restructured sites (described below).

Our effective tax rate for the second quarter of 2017 was 11%. After excluding the tax effects of non-IFRS adjustments, our non-IFRS adjusted effective tax rate for the second quarter of 2017 was 17%. Our non-IFRS adjusted effective tax rate for the second quarter of 2017 was determined by excluding $5.0 million of tax benefits from our IFRS tax expense for the period, comprised of tax benefits related to employee stock-based compensation expense of $0.4 million; tax benefits related to net restructuring, impairment and other charges of $1.0 million; tax benefits related to other solar charges of $0.4 million; and tax benefits of $3.2 million related to solar impairments recorded in prior quarters. Our effective tax rate for the six months ended June 30, 2017 was 18%. After excluding the tax effects of non-IFRS adjustments and tax recoveries related to restructured sites, our non-IFRS adjusted effective tax rate for the six months ended June 30, 2017 was 17%. Our non-IFRS adjusted tax effective tax rate for the six months ended June 30, 2017 was determined by excluding $5.8 million of tax benefits from our IFRS tax expense for the period, comprised of tax benefits related to employee stock-based compensation expense of $0.6 million; tax benefits related to net restructuring, impairment and other charges of $1.4 million; tax benefits related to other solar charges of $0.4 million; tax benefits of $3.2 million related to solar impairments recorded in prior quarters, and other tax benefits related to restructured sites of $0.2 million.

Our effective tax rate for the second quarter of 2016 was 26%. After excluding the tax effects of non-IFRS adjustments and tax write-offs related to restructured sites, our non-IFRS adjusted effective tax rate for the second quarter of 2016 was 23%. Our non-IFRS adjusted effective tax rate for the second quarter of 2016 was determined by excluding $0.3 million of net tax costs from our IFRS tax expense for the period, comprised of tax costs of $0.7 million related to restructured sites, offset by tax benefits related to employee stock-based compensation expense of $0.4 million. Our effective tax rate for the six months ended June 30, 2016 was 21%. After excluding the tax effects of non-IFRS adjustments and tax write-offs related to restructured sites, our non-IFRS adjusted effective tax rate for the six months ended June 30, 2016 was 17%. Our non-IFRS adjusted effective tax rate for the six months ended June 30, 2016 was determined by excluding $0.3 million of net tax benefits from our IFRS tax expense for the period, comprised of tax benefits related to employee stock-based compensation expense of $1.0 million; offset by tax costs related to restructured sites of $0.7 million.

(3)     Management uses non-IFRS free cash flow as a measure, in addition to IFRS cash flow provided by (used in) 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 (used in) operations after the purchase of property, plant and equipment (net of proceeds from the sale of certain surplus equipment and property), finance lease payments, repayments from a former solar supplier, and finance costs paid. In periods when it is relevant (third quarter of 2015), non-IFRS free cash flow also includes deposits received on the anticipated sale of real property (see note 18 to our 2016 annual audited consolidated financial statements). Note that non-IFRS free cash flow, however, does not represent residual cash flow available to Celestica for discretionary expenditures.

(4)     Management uses non-IFRS adjusted ROIC as a measure to assess the effectiveness of the invested capital we use to build products or provide services to our customers, by quantifying how well we generate earnings relative to the capital we have invested in our business. Our non-IFRS adjusted ROIC measure reflects non-IFRS operating earnings, working capital management and asset utilization. Non-IFRS adjusted ROIC is calculated by dividing non-IFRS adjusted EBIAT by average net invested capital. Net invested capital (calculated in the table below) 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 net invested capital for the quarter and a three-point average to calculate average net invested capital for the six-month period. A comparable measure under IFRS would be determined by dividing IFRS earnings before income taxes by net invested capital (which we have set forth in the charts above and below), however, this measure (which we have called IFRS ROIC), is not a measure defined under IFRS.

9

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

(1)             See footnote 4 of the previous table.

GUIDANCE SUMMARY

(1) For the third quarter of 2017, we anticipate a negative $0.06 to $0.12 per share (pre-tax) aggregate impact on net earnings on an IFRS basis for employee stock-based compensation expense, amortization of intangible assets (excluding computer software) and restructuring charges. We cannot predict changes in currency exchange rates, the impact of such changes on our operating results, or the degree to which we will be able to manage such impacts.
