Exhibit 99.2

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Sierra Wireless, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Sierra Wireless, Inc. (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations and comprehensive loss, equity and cash flows for each of the two years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 18, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

Sierra Wireless, Inc., together with its subsidiaries (collectively, "the Company", "we", "our", "Sierra Wireless") was incorporated under the Canada Business Corporations Act on May 31, 1993. Sierra Wireless is an Internet of Things (“IoT”) pioneer that empowers businesses and industries to transform and thrive in the connected economy.  Sierra Wireless offers a broad portfolio of edge-to-cloud solutions, comprised of embedded and networking devices seamlessly integrated with network connectivity services and cloud software. Original Equipment Manufacturers (“OEMs”), industrial companies, public safety agencies and enterprises worldwide rely on our expertise to deliver these fully integrated solutions to reduce complexity, turn data into intelligence, and get connected products and services quickly to market.

We have sales, engineering, and research and development teams located in offices around the world. The primary markets for our products are North America, Europe and Asia Pacific.

We operate our business under two reportable segments:

On November 18, 2020, the Company completed the divestiture of its automotive embedded module product line. Substantially all of the assets and operations related to its automotive embedded module product line were sold to Rolling Wireless (H.K.) Limited ("Rolling Wireless"), a consortium led by Fibocom Wireless Inc. of Shenzhen. In accordance with U.S. GAAP, the results of operations of the automotive business have been presented as discontinued operations in its consolidated statements of operations and comprehensive loss for the years ended December 31, 2021 and 2020.

COVID-19 Impact

In March 2020, the World Health Organization declared a global pandemic caused by the outbreak of the novel coronavirus specifically identified as COVID-19. It is not possible to reliably estimate the length or severity of these developments and the impact on the financial results of the Company in the future. There are significant uncertainties with respect to future development and impact to the Company related to COVID-19, including the duration, severity and scope of the outbreak, emergence of new variants of concern, and the measures taken by governments and businesses to contain the pandemic. As COVID-19 continues to significantly impact economies around the world, it creates significant uncertainty regarding the nearer term outlook for the markets where we provide our products and services, as well as significant uncertainties related to global supply chain tightness from key suppliers and manufacturing challenges that could constrain our ability to deliver and meet demand. In future periods, the effects of the pandemic may have material impacts on our financial results and the recoverable amount of our reporting units.

Ransomware Incident

On March 20, 2021, Sierra Wireless was the subject of a ransomware incident on our internal IT systems and corporate website. As a result of the incident, we temporarily halted production at our manufacturing sites. The investigation into the impact of the ransomware incident has been completed.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

Our consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").

Our consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned, from their respective dates of acquisition of control.  All inter-company transactions and balances have been eliminated on consolidation.

The consolidated financial statements have been prepared in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the year.  On an ongoing basis, management reviews its estimates, including those related to revenue recognition, such as determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price of performance obligations, and variable consideration; inventory obsolescence; estimated useful lives of long-lived assets; valuation of intangible assets and goodwill; royalty and warranty accruals; other liabilities; stock-based compensation; allowance for expected credit losses; income taxes; government assistance; measurement of impairment loss; restructuring costs; contingent consideration and commitments and contingencies, based on currently available information.  Actual amounts could differ from estimates.

Product revenue includes sales from embedded cellular modules, short range and GNSS wireless modules, intelligent routers and gateways, asset tracking and vertical market smart devices, antennas and accessories, and Smart SIMs. Recurring and other services revenue includes sales from cloud services, cellular connectivity services, managed connectivity and application services, software licenses, technical support services, extended warranty services, solution design and consulting services.

We recognize revenues when we satisfy performance obligations by transferring the control of promised products or services to customers. Product revenue is recognized at a point in time when a good is shipped or delivered to the customer. Recurring and other services revenue is recognized over time as the service is rendered or at a point in time upon completion of a service. Our customer contracts can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowances for returns and any taxes collected from customers.

Our products are generally highly dependent on, and interrelated with, the underlying firmware and cannot function without the firmware. In these cases, the hardware and the firmware are accounted for as a single performance obligation and revenue is recognized at the point in time when control is transferred to resellers and distributors, OEMs, or directly to end customers.

Certain customers may receive cash-based incentives or credits, which are accounted for as variable consideration. We estimate the amount of incentives or credits to be provided to customers and reduce revenue recognized. The variable consideration is included in the

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

transaction price to the extent that a significant reversal in the amount of cumulative revenue recognized is not expected to occur when the uncertainty associated with the variable consideration is subsequently resolved.

The expected costs associated with assurance-type warranty are recognized as expense when products are sold. Warranty service that is in addition to the assurance that the product complies with agreed upon specifications is a separate performance obligation; its revenue is recognized ratably over the service period.

Cloud and connectivity services are provided on either a subscription or consumption basis. Revenue related to cloud and connectivity services provided on a subscription basis is recognized ratably over the contract period. Revenue related to cloud and connectivity services provided on a consumption basis is recognized based on the customer utilization of such resources. Revenues from SIM activation and initial application setup are deferred and recognized over the estimated customer life on a straight-line basis.

Licenses for on-premise software provide the customer with a right to use the software as it exists when made available to the customer. Revenue from distinct on-premise licenses are recognized upfront at the point in time when the software is made available to the customer. Revenue from software maintenance, unspecified upgrades and technical support contracts are recognized over the period such items are delivered or services are provided. Technical support contracts extending beyond the current period are deferred and revenue is recognized over the applicable earning period.

Revenue from solution design and consulting services are recognized as services are being provided.

Contract acquisition and fulfillment costs

We recognize an asset for the incremental costs of obtaining or fulfilling a contract with a customer if we expect the benefit of those costs to be longer than one year. We have determined that certain sales incentive bonuses and initial setup costs of managed IoT services meet the requirements to be capitalized. We apply a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less.

The incremental costs of obtaining or fulfilling a contract with a customer are deferred and amortized over the estimated life of the customer relationship. We classify these deferred contract costs as current or non-current based on the timing of when we expect to recognize the expense. The current and non-current portions of deferred contract costs are included in Prepaids and other current assets and Other assets respectively in our consolidated balance sheets.

Significant judgment

We determine the transaction price of a customer contract by multiplying the unit price of a good or service with the committed order volume or service period.

Certain customers may receive cash-based incentives or credits, which are accounted for as variable consideration. We estimate the expected amount to be provided to customers and exclude it from the transaction price. Sales credits are included in Accounts payable and accrued liabilities in our consolidated balance sheets.

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

Our customer contracts can include various combinations of products and services. When a customer contract includes multiple performance obligations, we allocate the transaction price to each performance obligation on a relative standalone selling price basis. We generally determine standalone selling prices based on the price charged to customers or a combination of expected cost, plus a margin and residual methods.

Product revenue is recognized at a point in time when a good is shipped or delivered to the customer as it represents the transfer of control of the promised good to a customer. Cloud, connectivity, and managed service revenues are recognized over time as the customer simultaneously receives and consumes the benefits provided by our performance as we perform. Other service revenue is recognized at a point in time upon completion of a service.

Contract Balances

Receivables - We recognize a right to consideration as a receivable when only the passage of time is required before payment of that consideration is due.

Contract Assets - We recognize a right to consideration in exchange for goods or service that we have transferred to a customer as contract assets. Contract assets are comprised mainly of accrued revenue related to monthly IoT service subscriptions, which may include connectivity, cloud applications, and managed services. Contract assets are included in Accounts receivable in our consolidated balance sheet.

Deferred Revenue - We recognize an obligation to transfer goods or services to a customer for which we have received consideration from the customer as deferred revenue. Deferred revenue consists of advance payments and billings in excess of revenue recognized, which includes support, extended warranty, cloud application services, and activation fees.

Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days.

Research and development costs are expensed as they are incurred, including all costs incurred to establish the technological feasibility of a software product to be sold. Once the technological feasibility is reached, certain software development costs principally related to software coding, designing system interfaces and installation, and testing of the software, are capitalized.

We follow the cost reduction method of accounting for certain agreements, including government research and development funding, whereby the benefit of the funding is recognized as a reduction in the cost of the related expenditure when certain criteria stipulated under the terms of those funding agreements have been met, and there is reasonable assurance the research and development funding will be received.

Warranty costs are accrued upon the recognition of related revenue, based on our best estimates, with reference to past and expected future experience.  Warranty obligations are included in Accounts payable and accrued liabilities in our consolidated balance sheet.

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

We have intellectual property license agreements which generally require us to make royalty payments based on a combination of fixed fees and percentage of the revenue generated by sales of products incorporating the licensed technology.  We recognize royalty obligations in accordance with the terms of the respective royalty agreements.  Royalty costs are recorded as a component of cost of goods sold in the period when incurred.

Where agreements are not in place, we recognize our current best estimate of the royalty obligation in cost of goods sold, accrued liabilities and long-term liabilities. We base our estimate on the smallest salable unit (“SSU”) principle (i.e., the principle that any royalty obligations should be no more than a portion of the profits for a component within the product that implements the patented technology) as the appropriate methodology for determining FRAND standard essential patent (“SEP”) royalties. Using this principle, the royalty accrual on our products is based on the value of the patented technology in the chipset, representing the SSU that implements the technology.

Market development costs are charged to sales and marketing expense to the extent that the benefit is separable from the revenue transaction and the fair value of that benefit is determinable.  To the extent that such costs either do not provide a separable benefit, or the fair value of the benefit cannot be reliably estimated, such amounts are recorded as a reduction of revenue.

Income taxes are accounted for using the asset and liability method.  Deferred income tax assets and liabilities are based on temporary differences (differences between the accounting basis and the tax basis of the assets and liabilities), non-capital loss, capital loss, and tax credits carry-forwards are measured using the enacted tax rates and laws expected to apply when these differences reverse.  Deferred tax benefits, including non-capital loss, capital loss, and tax credits carry-forwards, are recognized to the extent that realization of such benefits is considered more likely than not.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations in the period that enactment occurs.

We include interest and penalties related to income taxes, including unrecognized tax benefits, in Income tax expense (recovery).

Liabilities for uncertain tax positions are recorded based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. We regularly assess the potential outcomes of examinations by tax authorities in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known.

We recognize the tax effects related to share-based payments at settlement or expiration in Income tax expense (recovery).

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

Stock options and restricted share units ("RSUs") granted to the Company’s key officers, directors and employees are accounted for using the fair value-based method.  Under this method, compensation cost for stock options is measured at fair value at the date of grant using the Black-Scholes valuation model and is expensed over the awards' vesting period using the straight-line method. Any consideration paid by plan participants on the exercise of stock options or the purchase of shares is credited to common stock together with any related stock-based compensation expense. Compensation cost for restricted share units with no market or performance conditions is measured at fair value at the date of grant which is the market price of the underlying security and is expensed over the awards' vesting period using the straight-line method. Compensation cost for market condition restricted share units is measured using a Monte Carlo valuation model. Compensation cost for performance-based internal performance benchmark restricted share units is measured at fair value at the time of grant which is the market price of the underlying security and adjusted for expected attainment with changes to expected attainment recorded in subsequent periods. We account for forfeitures in compensation expense when they occur.

Modification of awards are defined as changes to the terms or conditions of a share-based payment award. Improbable-to-probable modifications result in the reversal of the cumulative compensation costs of the original award incurred at the modification date and recognition of the incremental fair value of the modified award on a straight-line basis over the requisite service period.

Basic earnings (loss) per share is computed by dividing net earnings (loss) for the period by the weighted average number of company common shares outstanding during the reporting period.  Diluted earnings (loss) per share is computed using the treasury stock method.  When the effect of options and other securities convertible into common shares is anti-dilutive, including when the Company has incurred a loss for the period, basic and diluted earnings (loss) per share are the same. We use net loss from continuing operations as the control number in determining whether potential common shares are dilutive.

Our reporting currency is the U.S. dollar. We determine the functional currency of each of our foreign subsidiaries and their operating divisions based on the primary currency in which they operate.

Revenue and expense items denominated in foreign currencies are translated at exchange rates prevailing during the period.  Monetary assets and liabilities denominated in foreign currencies are translated at the period-end exchange rates.  Non-monetary assets and liabilities are translated at exchange rates in effect when the assets are acquired or the obligations are incurred.  Foreign exchange gains and losses are reflected in Net loss for the period.

We have foreign subsidiaries that are considered self-contained within their foreign jurisdiction, and accordingly, use the respective local currency as their functional currency.  The assets and liabilities of the foreign subsidiaries, including goodwill and fair value adjustments arising on acquisition, are translated at exchange rates at the balance sheet dates, equity is translated at historical rates, and revenue and expenses are translated at exchange rates prevailing during the

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

period.  The foreign exchange gains and losses arising from the translation are reported as a component of other comprehensive loss, as presented in note 24, Accumulated other comprehensive loss.

Cash and cash equivalents include cash and short-term deposits with original maturities of three months or less from the date of purchase. Cash equivalents are recorded at cost. The carrying amounts approximate fair value due to the short-term maturities of these instruments.

The Company classifies cash and cash equivalents as restricted cash when it is unavailable for withdrawal or use in its general operations. See note 25.

We maintain an allowance for lifetime expected credit losses that may result from our customer's inability to pay. Current and future economic conditions, historical information (including credit agency reports, if applicable), credit-worthiness, the line of business from which the customer accounts receivable arose, aging of receivables, known uncollectible accounts and changes in customer payment cycles are all considered when determining the expected credit losses related to accounts receivable. Amounts later determined and specifically identified to be uncollectible are charged against this allowance. If the financial condition of any of our customers deteriorates resulting in an impairment of their ability to make payments, we may increase our allowance.

We lease certain hardware devices to a small number of hardware distributors under sales-type leases which have terms ranging from 10 months to 48 months and bear interest at 5%.

We evaluate the credit quality of our financing receivables on an ongoing basis utilizing an aging of the accounts and write-offs, customer collection experience, the customer’s financial condition, known risk characteristics impacting the respective customer base, and other available economic conditions, to determine the appropriate allowance.

Derivatives, such as foreign currency forward and options contracts, may be used to economically hedge the foreign exchange risk on cash flows from commitments denominated in a foreign currency. Derivatives are recorded in Accounts receivable or Accounts payable and accrued liabilities and measured at fair value at each balance sheet date. Any resulting gains and losses from changes in the fair value are recorded in Foreign exchange gain (loss).

Inventories consist of electronic components and finished goods and are valued at the lower of cost or estimable realizable value, determined on a first-in-first-out basis.  Cost is defined as all costs that relate to bringing the inventory to its present condition and location under normal operating conditions. 

We review the components of our inventory and our inventory purchase commitments on a regular basis for excess and obsolete inventory based on estimated future usage and sales.  Write-downs in inventory value or losses on inventory purchase commitments depend on various items,

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

including factors related to customer demand, economic and competitive conditions, technological advances and new product introductions that vary from current expectations.  We believe that the estimates used in calculating the inventory provision are reasonable and properly reflect the risk of excess and obsolete inventory. If customer demands for our inventory are substantially less than our estimates, additional inventory write-downs may be required.

Property and equipment are stated at cost, less accumulated depreciation and amortization. We amortize our property and equipment on a straight-line basis over the following estimated economic lives:

Research and development equipment related amortization is included in Research and development expense.  Tooling, production, monitoring and certain network equipment related amortization is included in Cost of goods sold.  All other amortization is included in Amortization expense.

Leasehold improvements and leased vehicles are amortized on a straight-line basis over the lesser of their expected average service life or term of the lease.

When we sell property and equipment, we net the historical cost less accumulated depreciation and amortization against the sale proceeds and include the difference in Other income (expense).

The estimated useful life of intangible assets with definite lives is the period over which the assets are expected to contribute to our future cash flows.  When determining the useful life, we consider the expected use of the asset, useful life of any related intangible asset, any legal, regulatory or contractual provisions that limit the useful life, any legal, regulatory, or contractual renewal or extension provisions without substantial costs or modifications to the existing terms and conditions, the effects of obsolescence, demand, competition and other economic factors,  and the expected level of maintenance expenditures relative to the cost of the asset required to obtain future cash flows from the asset.

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

We amortize our intangible assets on a straight-line basis over the following specific periods:

In-process research and development ("IPRD") is included in research and development and are intangible assets acquired as part of business combinations.  Prior to their completion, IPRD are intangible assets with indefinite life and they are not amortized but subject to impairment test on an annual basis.

Research and development intangible asset related amortization is included in Research and development expense. All other intangible asset amortization is included in Amortization expense.

At inception of a contract, we apply judgment in assessing whether a contract is or contains a lease. This assessment involves determining whether we have control over the identified asset for a period of time in exchange for consideration. Operating leases are included in Operating lease right-of-use ("ROU") assets, Accounts payable and accrued liabilities, and Operating lease liabilities in our consolidated balance sheets. Finance leases are included in Property and equipment, Accounts payable and accrued liabilities, and Long-term obligations in our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term. Lease liabilities represent our obligation to make lease payments arising from the lease. We recognize operating lease right-of-use assets and liabilities at commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate as the discount rate for leases as the rates implicit in our leases are not readily determinable. Our incremental borrowing rate is estimated to approximate the interest on a collateralized basis with similar terms and payments and in economic environments where the leased asset is located. The operating lease ROU asset also includes any prepaid lease payments, initial direct costs and lease incentives. Our lease terms include non-cancelable periods and include options to renew the lease when it is reasonably certain that we will exercise that option.

Operating lease cost for lease payments is recognized on a straight-line basis over the term of the lease. Our lease agreements have lease and non-lease components, which we have elected to account for as a single lease cost.

We have elected not to record right-of-use assets and lease liabilities for short-term leases with a term of 12 months or less and recognize these short term leases to profit or loss on a straight-line basis over the lease term.  

Goodwill represents the excess of the purchase price of an acquired business over the fair value assigned to assets acquired and liabilities assumed in a business combination. We allocate

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

goodwill to reporting units based on the reporting unit expected to benefit from the business combination. Goodwill has an indefinite life, is not amortized, and is subject to an annual impairment test, on October 1 of every year, at the reporting unit level. Goodwill is tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value, or when there is a change in reporting units. These events or circumstances could include an adverse change in business climate, legal factors, operating performance indicators, competition or sale or disposition of a significant portion of a reporting unit. The goodwill impairment test compares the fair value of the reporting unit to its carrying amount, which includes the goodwill. When the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not to be impaired. If the carrying amount exceeds the implied fair value of the goodwill, an impairment loss is recognized equal to the amount by which the carrying amount of the reporting unit exceeds the reporting unit's fair value.

An evaluation of recoverability of goodwill requires judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the estimated fair value of each reporting unit. Significant judgments that are required on our part to estimate the fair value of reporting units include estimating future cash flows, determining appropriate discount rates, consideration of appropriate control premium, market conditions, and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit and may result in impairment charges in future periods. 

In March 2020, the World Health Organization declared a global pandemic caused by the outbreak of the novel coronavirus specifically identified as COVID-19. It is not possible to reliably estimate the length or severity of these developments and the impact on the financial results of the Company in the future. There are significant uncertainties with respect to future development and impact to the Company related to COVID-19, including the duration, severity and scope of the outbreak and the measures taken by governments and businesses to contain the pandemic.  As COVID-19 continues to significantly impact economies around the world, it creates significant uncertainty regarding the nearer term outlook for the markets where we provide our products and services. In future periods, the effects of the pandemic may have material impacts on our financial results and the recoverable amount of our reporting units. The COVID-19 pandemic and its impact on the economy is constantly evolving and presents many variables and contingencies for modeling.

In future periods, the effects of the pandemic may have material impacts on our anticipated revenue levels and the recoverable amount of our reporting units.

Long-lived assets, including property and equipment, and intangible assets other than goodwill, are assessed for potential impairment when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recovered. An impairment loss is recognized when the carrying amount of the long-lived asset group is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset group. Any required impairment loss is measured as the amount by which the carrying amount of a long-lived asset group exceeds its fair value and is recorded as a reduction in the carrying value of the related assets and a charge to operating results.

Comprehensive income (loss) includes net earnings (loss) as well as changes in equity from other non-owner sources. The other changes in equity included in comprehensive income (loss) are comprised of foreign currency cumulative translation adjustments.

In Canada and the United States, non-refundable investment tax credits are accounted for using the flow-through method whereby such credits are accounted for as a reduction of income tax expense in the period in which the credit arises.  In France, the investment tax credits are reported as a reduction of cost as the credits are refundable irrespective of taxable income.  

Certain figures presented in the consolidated financial statements have been reclassified to conform to the current year presentation. We reclassified certain Accounts Payable and Accrued Liabilities balances previously presented as of December 31, 2020. From 'Other' we reclassified $11,073 to 'Trade payables and accruals' and $8,897 to 'Sales credits' to better reflect the nature of balances (see note 22).

We report a disposal of a component or a group of components as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect of the Company's operations and financial results when the components meet the criteria to be classified as held for sale. At the time an operation qualifies for held-for-sale accounting, the operation is evaluated to determine whether or not its carrying amount exceeds its fair value less cost to sell. Any loss as a result of carrying amounts in excess of fair value less cost to sell is recorded in the period the operation qualifies for held-for-sale accounting. Assets, once classified as held for sale, are not subject to depreciation or amortization, and both the assets and any liabilities directly associated with the assets held for sale are classified as current in the Company’s consolidated balance sheets. When a portion of a reporting unit that constitutes a business is disposed of, goodwill associated with that business is included in the carrying amount of the business in determining the gain or loss on disposal. The amount of goodwill is based on the relative fair values of the business to be disposed of and the portion of the reporting unit that will be retained. Management judgment is required to (i) assess the criteria required to qualify for held-for-sale accounting and (ii) estimate fair value.

Our automotive business is presented as discontinued operations for all periods. Following the disposal, we retained certain royalty and warranty obligations related to the automotive business. Reversals of the royalty and warranty obligations are presented in discontinued operations. Our consolidated statements of cash flows include discontinued operations. See note 5c, Disposition of Automotive Business. Supplemental cash flow information relating to discontinued operations is disclosed separately in the note disclosure.

We account for our business combinations using the acquisition method.  Under this method, estimates we make to determine the fair values of acquired assets and liabilities assumed include judgments in our determinations of acquired intangible assets and assessment of the fair value of existing property and equipment.  Assumed liabilities can include litigation and other contingency reserves existing at the time of the acquisition.  Goodwill is recognized as of the acquisition date as the excess of the fair value of consideration transferred over the estimated fair values of net identifiable assets acquired and liabilities assumed at their acquisition date.  Acquisition related expenses are separately recognized from business combination and are expensed as incurred. 

When establishing fair values, we make significant estimates and assumptions, especially with respect to intangible assets.  Intangible assets acquired and recorded by us may include patents, intellectual property, customer relationships, brand, backlog and in-process research and development.  Estimates include but are not limited to the forecasting of future cash flows and discount rates.  From time to time, we may engage third-party firms to assist us in determining the fair value of assets and liabilities assumed.  Our estimates of fair values are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable.  As a result, actual results may differ from estimates impacting our earnings. 

Government grants are recognized when there is reasonable assurance that (a) the Company will comply with eligible requirements attached to the grant and (b) the grant will be received. Government grants are recorded as a reduction in the cost of the related expenditures (see note 9).

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, Measurement of Credit Losses on Financial Instruments ("ASC 326"), replacing the incurred loss impairment model that recognizes losses when a probable threshold is met with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased. The standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The new guidance on the current expected credit loss ("CECL") impairment model requires an estimate of expected credit loss, measured over the contractual life of an asset, that considers reasonable and supportable forecasts of future economic conditions in addition to historical experience and current conditions. The objective is to present the entity’s estimate of the net amount expected to be collected on the financial assets. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, net investment in leases recognized by lessor and off-balance sheet credit exposures not accounted for as insurance. In addition, ASC 326 made changes to the accounting for available for sale debt securities.

On January 1, 2020, the Company adopted ASC 326 using the modified retrospective method. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326. The Company recorded a net decrease to retained earnings of $779 as of January 1, 2020 for the cumulative effect of adopting ASC 326 as a result of measuring expected credit losses on trade accounts receivable.

The cumulative effect was allocated between continuing and discontinued operations as follows:

In December 2019, the FASB issued ASU 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes, including the methodology for calculating taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted ASU 2019-12 on January 1, 2021 and applied the new standard in determining tax expense for the year ended December 31, 2021. The adoption of this standard did not have a material impact on our consolidated financial statements and notes thereto and prior periods were not impacted.

In March 2020, the FASB issued an update to ASU 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which addresses the effects of reference rate reform on financial reporting. This would apply to companies meeting certain criteria that have contracts, hedging relationships and other transactions that reference London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 is effective for the Company beginning January 1, 2022 and a successor rate has been established for our Revolving Facility with CIBC (see note 27(b)). The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.

In October 2021, FASB issued ASU 2021-08 Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this ASU require an entity to recognize and measure contract assets and liabilities acquired in a business combination in accordance with Topic 606. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022 and should be applied prospectively to business combinations occurring on or after the effective date of the amendment. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.

In November 2021, the FASB issued ASU 2021-10 Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance (ASU 2021-10), which aims to provide increased transparency by requiring business entities to disclose information about certain types of government assistance they receive in the notes to the financial statements. ASU 2021-10 is effective for fiscal years beginning after December 15, 2021. The Company is currently assessing the impact of ASU 2021-10 on its consolidated financial statements.

Deferred tax assets and liabilities 

The tax effects of temporary differences that give rise to significant deferred tax assets and deferred tax liabilities were as follows at December 31:

At December 31, 2021, we have provided for a valuation allowance on our deferred tax assets of $183,230 (2020 — $168,133).

At December 31, 2021, we have Canadian non-capital loss carry-forwards of $47,880 that are available to be deducted against future Canadian taxable income. The Canadian non-capital loss carryforwards will expire in 2041. In addition, we have Canadian SR&ED expenditure carry-forwards of $23,642 that are available, indefinitely, to be deducted against future Canadian taxable income, investment tax credits of $26,833 and $12,985 available to offset future Canadian federal and provincial income taxes payable, respectively. The investment tax credits expire between 2025 and 2041. At December 31, 2021, our U.S. subsidiary has $6,445 of California research & development tax credits which may be carried forward indefinitely.

At December 31, 2021, net operating loss carry-forwards for our foreign subsidiaries were $83,838 for U.S. income tax purposes, of which, $27,849 may be carried forward indefinitely, and $55,989 expires between 2022 and 2037, $1 for Sweden income tax purposes, $38 for Norway income tax purposes, $94,426 for Luxembourg income tax purposes, of which, $40,240 may be carried forward indefinitely, and $54,186 expire between 2035 and 2038, and $259,233 for French income tax purposes. The Sweden, Norway, and French net operating loss carry-forward may be carried forward indefinitely. Our foreign subsidiaries may be limited in their ability to use foreign net operating losses in any single year depending on their ability to generate significant taxable income. In addition, the utilization of the U.S. net operating losses is also subject to ownership change limitations provided by U.S. federal and specific state income tax legislation. The amount of French net operating losses deducted each year is limited to €1.0 million plus 50% of

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

French taxable income in excess of €1.0 million. Our French net operating losses carry-forward is subject to the “continuity of business” requirement. Our French subsidiaries also have research tax credit carried forward of $2,321 and employment tax credit carried forward of $56 as at December 31, 2021. The French tax credits may be used to offset against corporate income tax and if any tax credits are not fully utilized within a three-year period following the year the tax credits are earned, it may be refunded by the French tax authorities. Tax loss and tax credits carry-forwards are denominated in the currency of the countries in which the respective subsidiaries are located and operate. Fluctuations in currency exchange rates could reduce the U.S. dollar equivalent value of these tax loss and research tax credit carry forwards in future years.

In assessing the realizability of our deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which temporary differences become deductible and the loss carry-forwards or tax credits can be utilized. Management considers projected future taxable income and tax planning strategies in making our assessment.

Accounting for uncertainty in income taxes 

At December 31, 2021, we had gross unrecognized tax benefits of $3,627 (2020 — $4,474).  Of this total, $598 (2020 — $559) represents the amount of unrecognized tax benefits that, if recognized, would favorably impact our effective tax rate.

Below is a reconciliation of the total amounts of unrecognized tax benefits for the years ended December 31:

We recognize interest expense and penalties related to unrecognized tax benefits within the provision for income tax expense on the consolidated statement of operations. At December 31, 2021, we had increased $3 (2020 - increased $50) for accruals of interest and penalties.

In the normal course of business, we are subject to audit by the Canadian federal and provincial taxing authorities, by the U.S. federal and various state taxing authorities and by the taxing authorities in various foreign jurisdictions. Tax years ranging from 2007 to 2021 remain subject to examination in Canada, the United States, the United Kingdom, France, Germany, Australia, New Zealand, China, Hong Kong, Brazil, South Africa, Japan, Korea, Taiwan, Italy, Sweden, Norway, India, Spain, and Luxembourg.

The Company regularly engages in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. The Company believes it is reasonably possible that certain tax matters may be concluded in the next 12 months. The Company estimates that the unrecognized tax benefits at December 31, 2021 could reduce by approximately $38 in the next 12 months.

Deferred taxes on foreign earnings

No provision for taxes has been provided on undistributed foreign earnings, as it is the Company’s intention to indefinitely reinvest undistributed earnings of its foreign subsidiaries. It is not practical to estimate the income tax liability that might be incurred if there is a change in management’s intention in the event that a remittance of such earnings occur in the future.

During 2021, $3.2 million of stock-based compensation expense was reversed as a result of changes of estimated achievement of service revenue target relating to PSUs (2020 — $0.6 million).

In connection with the recent executive leadership team change, certain equity awards were modified, resulting in the reversal of the cumulative compensation costs of the original award incurred at the modification date and recognition of the incremental fair value of the modified award on a straight-line basis over the requisite service period. In 2021, the Company recognized $1.4 million (2020 — nil) of incremental compensation expense relating to modification of awards and $3.9 million (2020 — $0.5 million) of compensation expense related to accelerated vesting of awards resulting from executive leadership changes.

Under the terms of the Company's Stock Option Plan (the “Plan”), the Board of Directors may authorize the grant of stock options to employees, officers and directors. At the Company's Annual General Meeting of Shareholders on June 2, 2021, shareholders approved a resolution to amend and restate the terms of the Plan. The amendments increased the maximum number of shares issuable pursuant to the Plan to 9.7% (increased from 8.9%) of the number of issued and outstanding common shares from time to time, provided that in no event will more than 7,000,000 common shares be issued as "incentive stock options intended to qualify under Section 422 of the United States Internal Revenue Code". In addition, the maximum number of shares issuable pursuant to the Plan, together with any shares issuable pursuant to other security-based compensation arrangements, shall not exceed 9.7% (increased from 8.9%) of the number of issued and outstanding common shares from time to time.

SIERRA WIRELESS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except where otherwise stated)

The Plan provides that the exercise price of a stock option will be determined on the date of grant and will not be less than the closing market price of the Company's stock at that date. Stock options generally vest over four years, with the first 25% vesting at the first anniversary date of the grant and the balance vesting in equal amounts at the end of each full succeeding month thereafter. The Company determines the expiry date of each stock option at the time it is granted, which cannot be more than five years after the date of the grant.

The fair value of stock options was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions:

There is no dividend yield as the Company does not pay, and does not plan to pay cash dividends on its common shares.  The expected stock price volatility is based on the historical volatility of the Company's daily stock closing prices over a period equal to the expected life of each stock option grant.  The risk-free interest rate is based on yields from risk-free instruments with a term equal to the expected term of the stock options being valued.  The expected life of options represents the period of time that the options are expected to be outstanding based on historical data of option holder exercise and termination behavior. Forfeitures are accounted for in compensation expense as they occur. We did not issue any stock options in 2021.

The following table presents stock option activity for the years ended December 31:

The intrinsic value of outstanding and exercised stock options is calculated as the quoted market price of the stock at the balance sheet date, or date of exercise, less the exercise price of the option.

The following table summarizes the stock options outstanding and exercisable at December 31, 2021:

The options outstanding at December 31, 2021 expire between March 10, 2022 and November 27, 2025.

As at December 31, 2021, the unrecognized stock-based compensation cost related to the non-vested stock options was $1,211 (2020 — $2,763), which is expected to be recognized over a weighted average period of 1.9 years (2020 — 2.4 years).

We have a market based restricted share unit plan and a treasury based restricted share unit plan with awards outstanding (collectively, the “RSPs”). The RSPs support our growth and profitability objectives by providing long-term incentives to employees and also encourage our objective of employee share ownership through the granting of RSUs. There is no exercise price or monetary payment required from the employees upon the grant of an RSU or upon the subsequent delivery of our common shares (or, in certain jurisdictions, cash in lieu at the option of the Company) to settle vested RSUs. The form and timing of settlement is subject to local laws. 

At the Company's Annual General Meeting of Shareholders on June 2, 2021, shareholders approved a resolution to amend the treasury based restricted share unit plan (the "Treasury Plan"). The amendments increased the maximum number of shares issuable pursuant to outstanding awards under the Treasury Plan to 9.7% (increased from 4.6%) of the number of issued and outstanding shares from time to time. In addition, the maximum number of shares issuable pursuant to all of our security-based compensation arrangements is 9.7% (increased from 8.9%) of the number of issued and outstanding shares. With respect to the market-based RSP, independent trustees purchase Sierra Wireless common shares over the facilities of the Toronto Stock Exchange and Nasdaq, which are used to settle vested RSUs. The existing trust funds are variable interest entities and are included in these consolidated financial statements as treasury shares held for RSU distribution. As at December 31, 2021, there were 1,053,177 market RSUs outstanding (2020 — 2,614,135).

Non-performance based RSUs vest over one to three years. RSUs vesting over one or two years cliff vest in one year or two years, respectively, and RSUs vesting over three years vest in equal amounts on each anniversary date of the grant. RSU grants to employees who are resident in France for French tax purposes will not vest before the second anniversary from the date of grant, and any shares issued are subject to an additional two year tax hold period. In addition, certain grants issued to employees who are resident in France for French tax purposes vest over three years in equal amounts on each anniversary date, with the first tranche subject to a hold period of one year.

We include a performance-based component to certain grants of units under our RSPs ("PSUs"). We have two types of PSUs, depending on their performance-based metric. PSUs, with a market condition, are measured against an external benchmark index. The fair value of these PSUs at date of grant are determined using the Monte Carlo simulation model. PSUs, with a performance condition, are measured against an internal performance benchmark based on achieving connectivity, software, and service revenue targets or cost savings initiatives or profitability targets. The fair value of these PSUs is based on the Company's stock price on the date of grant adjusted for expected attainment with changes to expected attainment recorded in subsequent periods. Generally, PSUs have a three year cliff-vesting.

In 2021, the Board of Directors approved the issuance of PSUs that are measured against financial metrics that are determined by the Company at the beginning of each fiscal year for the performance period. The determination of the number of awards that will be attained at vesting is based on achieving the financial metric target in each of three individual fiscal years. Each tranche contains an independent annual performance condition and cliff vest on the third anniversary date. Since the financial metric for each tranche is determined at the beginning of each fiscal year in the performance period, each tranche has a separate grant date and the fair value of the PSUs is determined at each grant date using the Company's stock price on grant date adjusted for expected attainment with changes to expected attainment recorded in subsequent periods. As at December 31, 2021, 10,777 PSUs are considered issued but not yet granted and are excluded in the below RSU continuity table.

The aggregate intrinsic value of outstanding RSUs is calculated as the quoted market price of the stock at the balance sheet date. The intrinsic value of vested and settled RSUs is calculated as the quoted market price of the stock at date of vesting.

The following table summarizes the RSU activity for the years ended December 31:

As at December 31, 2021, the total remaining unrecognized compensation cost associated with the RSUs totaled $17,984 (2020 — $30,055), which is expected to be recognized over a weighted average period of 2.0 years (2020 — 1.8 years).
