San Francisco, CA and Vancouver, BC- Maxar Technologies Ltd. ("Maxar" or the "Company", formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE and TSX: MAXR), a leading global provider of advanced space technology solutions for commercial and government markets, today reported financial results for the fourth quarter and year end December 31, 2017.

Effective with the fourth quarter of 2017, we have changed our reporting currency from the Canadian dollar to the U.S. dollar as the vast majority of our revenue, earnings and assets are based in U.S. dollars following the closing of the DigitalGlobe acquisition. Accordingly, all dollar amounts in this press release are expressed in U.S. dollars unless otherwise noted. Refer to the section entitled "Consolidated Results in Canadian Dollars" later in this press release for further information on our financial results in Canadian dollars.

Highlights from the quarter include:

• Consolidated revenue of $545.1 million
• Adjusted EBITDA of $180.9 million and margins of 33.2%
• Adjusted earnings of $66.5 million and adjusted earnings per share of $1.19
• Net earnings of $64.5 million and net earnings per share of $1.15

"We wrapped up a very busy year with a good quarter. The highlights included closing the DigitalGlobe transaction, renaming the company Maxar Technologies and dual-listing on the Toronto and New York Stock Exchanges as MAXR. We’ve created a unique integrated space and geospatial intelligence company with end-to-end solutions expertise to serve both commercial and government markets," stated Howard L. Lance, President and Chief Executive Officer. "We're making steady progress on delivering revenue and cost synergies of $55-110 million in EBITDA to be achieved by the end of 2019, and. I'm pleased to report that we have now included run rate $25 million in our 2018 outlook as these potential benefits have become a reality," he added. "Furthermore, we continue to make progress on our U.S. Access plan, with several new program awards and our facility clearance for the Palo Alto, CA satellite factory now being achieved. This paves the way to capture revenue opportunities in the months and years ahead. Finally, we made several key executive hires that have rounded out our senior team."

"The year ended on solid footing, with the company generating solid cash flows from operating activities and achieving a net debt-to-EBITDA ratio of 4.0, well under our covenant ceiling with our lenders and below our prior forecast," stated William McCombe, Executive Vice President and Chief Financial Officer. "As mentioned earlier, we changed our reporting currency to U.S. dollars effective with the fourth quarter. We also changed our reporting segments to recognize the distinctive nature and margin profiles of our Space Systems, Imagery and Services offering across our four brands," he added. "We are providing unaudited pro forma historical income statements by quarter for 2017 and 2016, in U.S. dollars, and using the new reporting segments, as if the former DigitalGlobe and Maxar businesses had been combined. We believe this provides relevant trend data to better understand Maxar's current financial results and the context for our 2018 guidance."

For the fourth quarter of 2017, consolidated revenue was $545.1 million compared to $376.6 million in 2016. Revenue increased from the acquisition of DigitalGlobe on October 5, 2017, offset in part by lower revenue from the company's Space Systems segment.

For the full year 2017, consolidated revenue was $1,631.2 million in 2017 compared to $1,557.5 million in 2016. Revenue increased due to the inclusion of DigitalGlobe revenue of $221.6 million for the period October 5, 2017 to December 31, 2017 and from higher revenue from contracts with the U.S. government and other customers to supply spacecraft and perform design studies for scientific research and development missions. These increases in revenue were partially offset by lower revenue from geostationary communications satellite construction activity compared to the prior year. The Space Systems segment contributed revenue of $1,259.6 million (2016 - $1,417.2 million), the Imagery segment contributed revenue of $228.4 million (2016 - $41.0 million) and the Services segment contributed revenue of $143.2 million (2016 - $99.3 million).

Adjusted EBITDA for the fourth quarter of 2017 was $180.9 million and EBITDA margins were 33.2%, compared to $66.3 million and 17.6% for the same period of last year. The EBITDA increase was driven largely by the DigitalGlobe acquisition referenced above offset in part by lower EBITDA from the Company’s Space Systems segment.

For the full year 2017, adjusted EBITDA was $378.7 million and adjusted EBITDA margin was 23.2%. Excluding the contribution from DigitalGlobe for the period Oct 5, 2017 to Dec 31, 2017, adjusted EBITDA in 2017 would have been $252.7 million and adjusted EBITDA margin percentage would have been 17.9%. This is compared to adjusted EBITDA of $267.6 million and adjusted EBITDA margin percentage of 17.2% for 2016. The increase in margin percentage was mainly due to a change in the mix of revenue between our various lines of business within our operating segments.

Adjusted earnings for the fourth quarter of 2017 were $66.5 million, or $1.19 per share, compared to $38.6 million, or $1.06 per share, for the same period of last year. On a full-year basis, adjusted earnings excluding the impact of specified items affecting comparability, was $172.0 million or $4.16 per share for 2017 compared to $159.5 million or $4.37 per share for 2016.

The Company declared a quarterly dividend of C$0.37 per common share payable on March 29, 2018 to shareholders of record at the close of business on March 15, 2018.

The following table provides selected fourth quarter and annual financial information for fiscal years 2017 and 2016.

2018 Financial Outlook

• Adjusted EPS of $4.50 to $4.70
• Cash flow from operations of $300M to $400M

Non-IFRS Financial Measures

In addition to results reported in accordance with IFRS, the Company disclosesadjusted earnings, adjusted earnings per shareandadjusted EBITDAas supplemental indicators of its financial and operating performance.

The Company definesadjusted earningsas net earnings excluding the impact of specified items affecting comparability, including, where applicable, non-operational income and expenses, amortization of acquisition related intangible assets, share-based compensation, and other gains or losses. The use of the term "non-operational income and expenses" is defined by the Company as those items or income and expense that do not impact operating decisions taken by the Company’s management and is based upon the way the Company’s management evaluates the performance of the Company's business for use in the Company’s internal management reports. Income tax expense on adjusted earnings is computed using the substantively enacted income tax rate, adjusted to account for the specified items affecting comparability.Adjusted earnings per shareis calculated using diluted weighted average shares outstanding and does not represent actual earnings per share attributable to shareholders. The Company believes that the disclosure of adjusted earnings and adjusted earnings per share allows investors to evaluate the operational and financial performance of the Company’s ongoing business using the same evaluation measures that its management uses, and is therefore a useful indicator of the Company's performance or expected performance of recurring operations.

The Company definesadjusted EBITDAas earnings before interest, taxes, depreciation and amortization, and adjusted for items affecting comparability as specified in the calculation of adjusted earnings. Adjusted EBITDA is presented on a basis consistent with the Company's internal management reports. The Company discloses adjusted EBITDA to capture the profitability of its business before the impact of items not considered in management’s evaluation of operating unit performance.

Adjusted earnings, adjusted earnings per share and adjusted EBITDA do not have any standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other companies. The Company cautions readers to consider these non-IFRS financial measures in addition to, and not as an alternative for, measures calculated in accordance with IFRS.

Reconciliation of adjusted EBITDA and adjusted earnings to net earnings

The Company's MD&A for the fourth quarter and year-end December 31, 2017 provides additional information regarding these financial metrics and the specified items affecting the comparability of net earnings.

PRO FORMA FINANCIAL INFORMATION

The following unaudited pro forma financial information gives effect to the Company's acquisition of DigitalGlobe using the acquisition method of accounting for business combinations with the Company identified as the acquirer, and is based on the respective historical unaudited condensed consolidated financial statements of the Company and DigitalGlobe for the periods presented below. In determining these amounts, management has conformed DigitalGlobe's historical financial results originally prepared under U.S. general accepted accounting principles to IFRS and has assumed that the fair value adjustments, determined provisionally, that arose on the date of acquisition would have been the same if the acquisition had occurred on January 1, 2016. In addition, DigitalGlobe's historical financial results have been adjusted to reflect the revenue and expenses of The Radiant Group, Inc. ("Radiant") as if DigitalGlobe's acquisition of Radiant had occurred on January 1, 2016. Revenue and direct costs, selling, general and administration expense have been adjusted to reflect the elimination of intra entity transactions during the periods and other expense has been adjusted to reflect the elimination of transaction related expenses.

This unaudited pro forma financial information is for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved if the acquisition had been completed at the beginning of the period for the periods presented, nor do they purport to project the results of operations of the combined entities for any future period or as of any future date. This unaudited pro forma financial information may not be useful in predicting the results of operations of the combined company in the future. The actual results of operations may differ significantly from this pro forma financial information.

Any such forward-looking statements are subject to a number of risks and uncertainties that could cause actual results and expectations to differ materially from the anticipated results or expectations expressed in this Earnings Release. The Company cautions readers that should certain risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary significantly from those expected. The risks that could cause actual results to differ materially from current expectations include, but are not limited to: the Company’s ability to generate a sustainable order rate for its satellite manufacturing operations in a market where the number of satellite construction contracts awarded varies annually; changes in government policies, priorities, regulations or government agency mandates, or funding levels through agency budget reductions, the imposition of budgetary constraints, failure to exercise renewal options, or a decline in government support or deferment of funding for programs in which the Company or its customers participate; the Company’s ability to effectively execute its U.S. government access plan and realize anticipated benefits of contract awards from the U.S. government and failure by the Company to comply with U.S. regulations could result in penalties or suspension; the risk that security clearances or accreditations will not be granted to or maintained by certain U.S. subsidiaries of the Company subject to the requirements of the National Industrial Security Program Operating Manual or other security requirements, which is a prerequisite for their ability to obtain and perform on classified contracts for the U.S. government; the loss or damage to any of the Company's satellites; delays in the construction and launch of any of the Company's satellites; the Company's ability to achieve and maintain full operational capacity of all of its satellites; interruption or failure of the Company's ground systems and other infrastructure; quality issues, failure of systems to meet performance requirements, potential for product liability, or the occurrence of defects in products or systems could result in lost revenue and harm to the Company's reputation; failure to anticipate changes in technology, technical standards and offerings or comply with the requisite standards, or failure to maintain technological advances and offer new products to retain customers and market position; significant competition with competitors that are larger or have greater resources, and where foreign currency fluctuations may increase competition from the Company's non-United States competitors; changes in regulations, telecommunication standards and laws in the countries in which the Company conducts business; export restrictions or the inability to obtain export approvals; failure to obtain necessary regulatory approvals and licenses, including those required by the United States government; a competitive advantage for competitors not subject to the same level of export control or economic sanctions laws and regulations faced by the Company; exposure to fines and/or legal penalties under Canadian and U.S. securities regulations; exposure to fines and/or legal sanctions under anti-corruption laws; the Company's ability to attract and retain qualified personnel; reliance on information technology systems and threats of disruption from security breaches and cyber-attacks; the Company's ability to receive satellite imagery, including from third parties for resale and performance issues on the Company's on-orbit satellites; potential infringement of the intellectual property rights of others and inadequate protection of the Company's intellectual property rights; failure to identify, acquire, obtain the required regulatory approvals, or profitably manage additional businesses or successfully integrate any acquired businesses, products or technologies into the Company without substantial expenses, delays or other operational, regulatory, or financial problems; the Company's ability to obtain certain satellite construction contracts depends, in part, on its ability to provide the customer with partial financing of working capital and any financing provided by the Company may not be repaid or the Company may be called upon to make payments; uncertainty in financing arrangements and failure to obtain required financing on acceptable terms, or credit agreements may contain restrictive covenants which may be limiting; risks inherent with performance on fixed price contracts, particularly the ability to contain cost overruns and schedule delays; certain customers are highly leveraged and may not fulfill their contractual payment obligations, including vendor financing; the risk that the Company will not be able to access export credit financing to facilitate the sale of the Company's communication satellites and other products to non-Canadian and non-United States customers; exposure to foreign currency fluctuations, interest rates, energy and commodity prices, trade laws and the effects of governmental initiatives to manage economic conditions; natural disasters or other disruptions affecting the Company's operations; failure to comply with environmental regulations; insufficient insurance against material claims or losses; and general business and economic conditions in Canada, the U.S. and other countries in which the Company conducts business.

There may be additional risks and uncertainties applicable to the Company related to its acquisition of DigitalGlobe, including that: the Company may not realize all of the expected benefits of the acquisition or the benefits may not occur within the time periods anticipated; the Company incurred substantial transaction fees and costs in connection with the acquisition; significant demands will be placed on the managerial, operational and financial personnel and systems of the Company to support the expansion of operations as a result of the acquisition; the Company may not have discovered undisclosed liabilities in the course of the due diligence review of DigitalGlobe and the Company as a successor owner may be responsible for such undisclosed liabilities; and the Company is a target of appraisal proceedings which could result in substantial costs.
