Unless otherwise specified, all dollar amounts referred to in this AIF are expressed in United States dollars and all references to "US$" are to United States dollars and all references to "C$" are to Canadian dollars. Unless otherwise indicated, all financial statements and information included in, or incorporated by reference into, this AIF is determined using generally accepted accounting principles as in effect in the United States ("GAAP") and presented as at December 31, 2018.

Notes:

All directors stand for election or re-election annually.

Further background information regarding the directors of the Company will be set out in the Meeting Circular, the relevant sections of which are incorporated by reference herein and which will be available under our SEDAR profile at www.sedar.com.

Ownership

As of February 20, 2019, the directors and executive/key officers of the Company, as a group, owned, or controlled or directed, directly or indirectly, 2,690,295 Subordinate Voting Shares and 1,325,694 Multiple Voting Shares, which represent 7.8% of the total Subordinate Voting Shares and 100% of the total Multiple Voting Shares, in each case, outstanding on such date. The directors and executive/key officers, as a group, controlled 50.5% of the total voting rights as of such date when all Multiple Voting Shares and Subordinate Voting Shares are considered. Mr. Hennick controls all of the Multiple Voting Shares.

Legal proceedings and regulatory actions

There are no legal proceedings to which FirstService is a party to, or in respect of which, any of the property of FirstService is the subject of, which is or was material to FirstService during 2018, and FirstService is not aware of any such legal proceedings that are contemplated. In the normal course of operations, FirstService is subject to routine immaterial claims and litigation incidental to its business. Litigation currently pending or threatened against FirstService includes disputes with former employees and commercial liability claims related to services provided by FirstService. FirstService believes resolution of such proceedings, combined with amounts set aside, will not have a material impact on the Company's financial condition or the results of operations.

During 2018, there were no penalties or sanctions imposed against FirstService by a court relating to provincial and territorial securities legislation or by a securities regulatory authority, nor were there any other penalties or sanctions imposed by a court or regulatory body against FirstService and, during 2018, FirstService did not enter into any settlement agreements before a court relating to provincial and territorial securities legislation or with a securities regulatory authority.

Reconciliation of non-GAAP financial measures

In this AIF, we make reference to "adjusted EBITDA" and "adjusted EPS," which are financial measures that are not calculated in accordance with GAAP.

Adjusted EBITDA is defined as net earnings, adjusted to exclude: (i) income tax; (ii) other expense (income); (iii) interest expense; (iv) depreciation and amortization; (v) goodwill impairment charge; (vi) acquisition-related items; and (vii) stock-based compensation expense. The Company uses adjusted EBITDA to evaluate its own operating performance and its ability to service debt, as well as an integral part of its planning and reporting systems. Additionally, this measure is used in conjunction with discounted cash flow models to determine the Company's overall enterprise valuation and to evaluate acquisition targets. Adjusted EBITDA is presented as a supplemental measure because the Company believes such measure is useful to investors as a reasonable indicator of operating performance because of the low capital intensity of its service operations. The Company believes this measure is a financial metric used by many investors to compare companies, especially in the services industry. This measure is not a recognized measure of financial performance under GAAP in the United States, and should not be considered as a substitute for operating earnings, net earnings from operations or cash flow from operating activities, as determined in accordance with GAAP. The Company's method of calculating adjusted EBITDA may differ from other issuers and accordingly, this measure may not be comparable to measures used by other issuers. A reconciliation of net earnings from operations to adjusted EBITDA appears below.

Adjusted EPS is defined as diluted net earnings (loss) per share, adjusted for the effect, after income tax, of: (i) the non-controlling interest redemption increment; (ii) acquisition-related items; (iii) amortization of intangible assets recognized in connection with acquisitions; (iv) goodwill impairment charges; (v) stock-based compensation expense; (vi) a stock-based compensation tax adjustment related to a US GAAP change; and (vii) an income tax recovery on enactment of US Tax Reform. The Company believes this measure is useful to investors because it provides a supplemental way to understand the underlying operating performance of the Company and enhances the comparability of operating results from period to period. Adjusted EPS is not a recognized measure of financial performance under GAAP, and should not be considered as a substitute for diluted net earnings per common share from operations, as determined in accordance with GAAP. The Company's method of calculating this non-GAAP measure may differ from other issuers and, accordingly, this measure may not be comparable to measures used by other issuers. A reconciliation of diluted net earnings (loss) per common share from operations to adjusted EPS appears below.

We believe that the presentation of adjusted EBITDA and adjusted EPS, which are non-GAAP financial measures, provides important supplemental information to management and investors regarding financial and business trends relating to the Company's financial condition and results of operations. We use these non-GAAP financial measures when evaluating operating performance because we believe that the inclusion or exclusion of the items described above, for which the amounts are non-cash or non-recurring in nature, provides a supplemental measure of our operating results that facilitates comparability of our operating performance from period to period, against our business model objectives, and against other companies in our industry. We have chosen to provide this information to investors so they can analyze our operating results in the same way that management does and use this information in their assessment of our core business and the valuation of the Company. Adjusted EBITDA and adjusted EPS are not calculated in accordance with GAAP, and should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Non-GAAP financial measures have limitations in that they do not reflect all of the costs or benefits associated with the operations of our business as determined in accordance with GAAP. As a result, investors should not consider these measures in isolation or as a substitute for analysis of our results as reported under GAAP.

Risk factors

Readers should carefully consider the following risks, as well as the other information contained in this AIF and our management's discussion and analysis for the year ended December 31, 2018. If any of the following risks actually occurs, our business could be materially harmed. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties, including those of which we are currently unaware or we currently deem immaterial, may also adversely affect our business.

Risks relating to our Business

Economic conditions, especially as they relate to credit conditions and consumer spending

During periods of economic slowdown or contraction, our business is impacted directly. Consumer spending directly impacts our FirstService Brands operations businesses because as consumers spend less on property services, our revenues decline. These factors could also negatively impact the timing or the ultimate collection of accounts receivable, which would negatively impact our operating revenues, profitability and cash flow.

Residential real estate property values, resale rates and general conditions of financial liquidity for real estate transactions

We provide various services at residential properties in our FirstService Residential and FirstService Brands operating divisions. Property values and consumer confidence are strongly correlated with demand for our services, including painting, closet installation, general maintenance, collections and resale processing.

Extreme weather conditions impact demand for our services or our ability to perform those services

Natural disasters, such as hurricanes, can have a direct impact in our FirstService Residential and FirstService Brands operations. These events damage property, which require various services that our companies offer, such as restoration and large-scale landscaping. They may also harm our employees, facilities and franchisees, resulting in an inability to serve clients and generate revenues.

Economic deterioration impacts our ability to recover goodwill and other intangible assets

Expectations of future earnings drive the recoverability of goodwill and other intangible assets, which are tested, at least, on an annual basis. A future deterioration of operating performance may necessitate additional non-cash impairment charges.

Ability to generate cash from our businesses to fund future acquisitions and meet our debt obligations

We rely on our businesses to generate the necessary cash to service our financial obligations. As at December 31, 2018, we have $330.6 million of debt outstanding ($268.2 million net of cash) that will be required to be refinanced or repaid over the next eight years. We also have $67.5 million of available un-drawn credit at December 31, 2018. To date, we have been able to meet all of our debt obligations, however with a decline in performance in some of our businesses, surplus cash may not be available to be remitted which may result in the inability to meet a debt repayment.

An important component of our growth strategy is strategic and selective acquisitions, which we tend to complete with cash. Although we have a revolving credit facility available to us as noted elsewhere in this AIF, we also rely on surplus cash on hand to fund acquisitions. If cash on hand is not available and our revolving credit facility is fully utilized, then future acquisitions may not be possible.

The effects of changes in foreign exchange rates in relation to the U.S. dollar on our Canadian dollar denominated revenues and expenses

We generate less than 10 % of our revenues outside the United States. Consequently, a portion of our consolidated results are impacted directly by fluctuations in the relative strength of the U.S. dollar versus the Canadian dollar currency. In the future, we may acquire additional international operations. In such event, the impact of foreign currency exchange rate fluctuations may increase.

Competition in the markets served by the Company

We operate in highly competitive markets. Changes in the source and intensity of competition in the markets served by us impact the demand for our services and may result in additional pricing pressures. The relatively low capital cost of entry to certain of our businesses has led to strong competitive markets, including regional and local owner-operated companies. Regional and local competitors operating in a limited geographic area may have lower labour, benefits and overhead costs. The principal methods of competition in our businesses include name recognition, quality and speed of service, pricing, customer satisfaction and reputation. No assurance can be given that we will be able to compete successfully against current or future competitors and that the competitive pressures that we face will not result in reduced market share or negatively impact our financial performance.

Labour shortages or increases in wage and benefit costs

As a services company, our primary asset is the human capital that comprises our workforce. In particular, we rely on property managers, franchisees and other skilled staff to generate revenues. A shortage, or increase in wage and benefit costs, of this human capital could reduce our revenues and profitability.

The effects of changes in interest rates on our cost of borrowing

As at December 31, 2018, we had $177.2 million of debt at variable interest rates. As a result, changes in base rates such as LIBOR affect our interest expense as these base rates fluctuate. On our fixed rate debt, we have from time-to-time entered into fixed-for-floating interest rate swaps, where advantageous, to convert the fixed interest payments to floating. These swaps are intended to manage interest rate sensitivity and reduce overall interest costs.

Continued compliance with the financial covenants under our debt agreements, or our ability to negotiate a waiver of certain covenants with our lenders

A prolonged decline in our earnings performance could result in a non-compliance with one or more financial covenants. If the Company fails to meet its payment or other obligations under its debt agreements, the lenders will be entitled to demand immediate repayment of all amounts owing and thereafter, if unpaid, exercise their secured creditor rights.

Unexpected increases in operating costs, such as insurance, workers' compensation, health care and fuel prices

As a services company, the costs of providing services to our customers can fluctuate. Certain operating expenses are based on market rates which we cannot control and, absent an offsetting price increase in our services, have a direct impact on our operating margins.

Changes in the frequency or severity of insurance incidents relative to our historical experience

Adverse changes in claims experience could increase our insurance costs and/or increase the risk of being unable to renew insurance coverage at our operations. In each of our operating segments, we effectively self-insure certain risks, with a layer of third-party insurance for catastrophic claims. An increase in the frequency or severity of claims in these areas could materially affect our financial position and results of operations. There can be no assurance that we will be able to obtain insurance coverage on favourable economic terms in the future.

Our ability to make acquisitions at reasonable prices and successfully integrate acquired operations

As an acquisitive organization, we actively pursue acquisitions to expand our footprint and services offerings as well as supplement existing businesses. Not only does our acquisition strategy depend on the continued availability of suitable targets, it also depends on the ability to negotiate favorable terms and conditions. Another risk with acquisitions is the ability to integrate the acquired business into an existing service line.

Certain of our businesses operate in industries and are subject to a variety of changing laws and regulations

Certain of our operations and employees are subject to various licensing laws, codes and standards and other laws and regulations. Changes in laws or regulations could require us to change the way we operate or to utilize resources to maintain compliance, which could increase costs or otherwise alter operations. In addition, failure to comply with any applicable laws or regulations could result in fines or revocation of permits and licenses. If applicable laws and regulations were to change or if we failed to comply, our business, financial condition and results of operations could be adversely affected.

We are exposed to greater risks of liability for employee acts or omissions, or installation/system failure, in our fire protection businesses than may be inherent in other businesses

The nature of the fire protection services we provide exposes us to the risks that we may be held liable for employee acts or omissions or installation/system failures. In an attempt to reduce this risk, our installation, service and/or maintenance agreements and other contracts contain provisions limiting our liability in such circumstances, and we typically maintain liability insurance to mitigate such risk. However, in the event of litigation, it is possible that contract limitations may be deemed not applicable or unenforceable, that our insurance coverage is not adequate, or that insurance carriers deny coverage of our claims. As a result, such employee acts or omissions or installation/system failures could have an adverse effect on our business, financial condition, results of operations and cash flows.

Declaration of dividends on Common Shares

Future dividends on the Common Shares will depend on the Company's results of operations, financial condition, capital requirements, general business conditions and other factors that the Company's Board of Directors may deem relevant. Additionally, under our revolving credit facility, the Company is not permitted to pay dividends, whether in cash or in specie , in the circumstances of an event of default thereunder occurring and continuing or an event of default occurring as a consequence thereof.

Risks arising from any regulatory review and litigation

While management is not currently aware of any formal regulatory reviews or investigations, the commencement of any such reviews or investigations may result in the diversion of significant management attention and resources and, if securities or other regulators determine that a violation of securities or other laws may have occurred, or has occurred, the Company or its officers and directors may receive notices regarding potential enforcement action or prosecution and could be subject to civil or criminal penalties or other remedies. For example, the Company or its officers could be required to pay substantial damages, fines or other penalties, the regulators could seek an injunction against the Company or seek to ban an officer or director of the Company from acting as such, any of which actions would have a material adverse effect on the Company.

Intellectual property and other proprietary rights that are material to our business

Our ability to compete effectively depends in part on our rights to service marks, trademarks, trade names and other intellectual property rights we own or license. We have not sought to register every one of our marks in every jurisdiction in which they are used. Furthermore, because of the differences in foreign trademark, patent and other intellectual property or proprietary rights laws, we may not receive the same protection in other jurisdictions as we would in Canada or the United States. If we are unable to protect our proprietary information and brand names, we could suffer a material adverse effect on our business, financial condition or results of operations. Litigation may be necessary to enforce our intellectual property rights and protect our proprietary information, or to defend against claims by third parties that our products or services infringe their intellectual property rights. Any litigation or claims brought by or against us could result in substantial costs and diversion of our resources. A successful claim of trademark, patent or other intellectual property infringement against us, or any other successful challenge to the use of our intellectual property, could subject us to damages or prevent us from providing certain services under our recognized brand names, which could have a material adverse effect on our business, financial condition or results of operations.

Disruptions or security failures in our information technology systems

Our information technology systems facilitate our ability to monitor, operate and control our operations. While we have disaster recovery plans in place, any disruption in these plans or the failure of our information technology systems to operate as expected could, depending on the magnitude of the problem, adversely affect our operating results by limiting, among other things, our capacity to monitor, operate and control our operations effectively. In addition, because our systems contain information about individuals and businesses, our failure to maintain the security of the data we hold, whether the result of our own error or the malfeasance or errors of others, could harm our reputation or give rise to legal liabilities relating to violations of privacy laws or otherwise, which may lead to lower revenues, increased costs and other material adverse effects on our results of operations.

Multiple Voting Shares and a change of control

The existence of the Multiple Voting Shares results in various impediments on the ability or desire of a third party to acquire control of the Company. This may discourage, delay or prevent a change of control of the Company or an acquisition of the Company at a price that shareholders may find attractive. The existence of the Multiple Voting Shares also may discourage proxy contests and make it difficult or impossible for the Company's holders of Subordinate Voting Shares to elect directors and take other corporate actions.

Blank cheque preference shares

The Company has the right to issue so-called "blank cheque" preference shares which may affect the voting and liquidation rights of holders of Common Shares. The Company's Board of Directors is authorized, without any further shareholder approval, to issue one or more additional series of preference shares in an unlimited number and to set the rights, privileges, restrictions and conditions attached thereto.

Political conditions, including any outbreak or escalation of terrorism or hostilities and the impact thereof on our business

Political events and situations can have an effect on the Company's operations. Events could occur that may hamper our ability to manage operations, extract cash and implement FirstService policies in certain regions.

Changes in government policies at the federal, state/provincial or local level that may adversely impact our businesses

Changes in laws and regulation at the different jurisdictional levels can have a direct effect on our operations. It is difficult to predict the future impact of a change in legislative and regulatory requirements affecting our businesses. The laws and regulations applicable to our businesses will likely change in the future and affect our operations and financial performance. In addition, if we were to fail to comply with any applicable law or regulation, we could be subject to substantial fines or damages, be involved in litigation, suffer losses to our reputation and suffer the loss of licenses or penalties that may affect how our business is operated, which, in turn, would have a material adverse effect on our business, financial condition and results of operations.

Interest of management and others in material transactions

Except as described below or elsewhere in this AIF, no director of FirstService, executive officer of FirstService, or person or company that beneficially owns, or controls or directs more than 10% of any class or series of voting securities of FirstService, or any associate or affiliate of any of the foregoing persons, has or has had any material interest in any transaction within the last three years, or during the current year, that has materially affected or is reasonably expected to materially affect FirstService or any of its subsidiaries.

Material contracts

The only contracts that can reasonably be regarded as material to us, other than contracts entered into in the ordinary course of business, are as follows:

Copies of the above material contracts are available on FirstService's SEDAR profile at www.sedar.com.

Cease trade orders, bankruptcies, penalties or sanctions

To the best of the knowledge of the Company:

Conflicts of interest

Certain directors and officers of the Company are engaged in and will continue to engage in activities outside the Company, and as a result, certain directors and officers of the Company may become subject to conflicts of interest. The Business Corporations Act (Ontario) provides that in the event that a director or officer has an interest in a contract or proposed contract or agreement, the director or officer shall disclose his or her interest in such contract or agreement and, in the case of directors, shall refrain from voting on any matter in respect of such contract or agreement unless otherwise provided under the Business Corporations Act (Ontario). To the extent that conflicts of interest arise, such conflicts will be resolved in accordance with the provisions of the Business Corporations Act (Ontario).

As at the date hereof, the Company is not aware of any existing or potential material conflicts of interest between the Company and a director or officer of the Company.
