Corporate Profile

Cousins Properties Incorporated (the “Registrant” or “Cousins”) is a Georgia corporation, which has elected to be taxed as a real estate investment trust (“REIT”). Cousins conducts substantially all of its business through Cousins Properties LP ("CPLP"), a Delaware limited partnership. Cousins owns approximately 98% of CPLP, and CPLP is consolidated with Cousins for financial reporting purposes. CPLP also owns Cousins TRS Services LLC ("CTRS"), a taxable entity which owns and manages its own real estate portfolio and performs certain real estate related services for other parties. Cousins, CPLP, their subsidiaries, and CTRS combined are hereafter referred to as “we,” “us,” “our,” and the “Company.” Our common stock trades on the New York Stock Exchange under the symbol “CUZ.”

Our operations are conducted through a number of segments based on our method of internal reporting, which classifies operations by property type and geographical area. For financial information related to each of our operating segments, see note 18 to the consolidated financial statements included in this Annual Report on Form 10-K.

Company Strategy

Our strategy is to create value for our stockholders through ownership of the premier urban office portfolio in the Sunbelt markets, with a particular focus on Georgia, Texas, North Carolina, Florida, and Arizona. This strategy is based on a disciplined approach to capital allocation that includes value-add acquisitions, selective development projects, and timely dispositions of non-core assets. This strategy is also based on a simple, flexible, and low-leveraged balance sheet that allows us to pursue investment opportunities at the most advantageous points in the cycle. To implement this strategy, we leverage our strong local operating platforms within each of our major markets.

2017 Activities

During 2017, we repositioned our portfolio of properties by reducing exposure in Atlanta and strategically exiting the Orlando and South Florida markets. During the year, we commenced two new development projects and completed two new development projects. At year-end, we had five development projects in process; our share of the total expected costs of these projects totaled $491 million . We also improved our balance sheet by issuing common equity, repaying four mortgage loans assumed in the merger with Parkway Properties, Inc. ("Parkway") with above market interest rates, and closing a private placement of unsecured debt. The following is a summary of our significant 2017 activities:

Investment Activity

Environmental Matters

Our business operations are subject to various federal, state, and local environmental laws and regulations governing land, water, and wetlands resources. Among these are certain laws and regulations under which an owner or operator of real estate could become liable for the costs of removal or remediation of certain hazardous or toxic substances present on or in such property. Such laws often impose liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous or toxic substances. The presence of such substances, or the failure to properly remediate such substances, may subject the owner to substantial liability and may adversely affect the owner’s ability to develop the property or to borrow using such real estate as collateral.

We typically manage this potential liability through performance of Phase I Environmental Site Assessments and, as necessary, Phase II environmental sampling, on properties we acquire or develop, although no assurance can be given that environmental liabilities do not exist, that the reports revealed all environmental liabilities, or that no prior owner created any material environmental condition not known to us. In certain situations, we have also sought to avail ourselves of legal and regulatory protections offered by federal and state authorities to prospective purchasers of property. Where applicable studies have resulted in the determination that remediation was required by applicable law, the necessary remediation is typically incorporated into the acquisition or development activity of the relevant property. We are not aware of any environmental liability that we believe would have a material adverse effect on our business, assets, or results of operations.

Certain environmental laws impose liability on a previous owner of a property to the extent that hazardous or toxic substances were present during the prior ownership period. A transfer of the property does not necessarily relieve an owner of such liability. Thus, although we are not aware of any such situation, we may have such liabilities on properties previously sold. We believe that we and our properties are in compliance in all material respects with applicable federal, state, and local laws, ordinances, and regulations governing the environment.

Competition

We compete with other real estate owners with similar properties located in our markets and distinguish ourselves to tenants/buyers primarily on the basis of location, rental rates/sales prices, services provided, reputation, and the design and condition of the facilities. We also compete with other real estate companies, financial institutions, pension funds, partnerships, individual investors, and others when attempting to acquire and develop properties.

Executive Offices; Employees

Our executive offices are located at 3344 Peachtree Road NE, Suite 1800, Atlanta, Georgia 30326-4802. On December 31, 2017 , we employed 261 people.

Set forth below are the risks we believe investors should consider carefully in evaluating an investment in the securities of Cousins Properties Incorporated.

General Risks of Owning and Operating Real Estate

Our ownership of commercial real estate involves a number of risks, the effects of which could adversely affect our business.

General economic and market risks . Our assets are subject to general economic and market risks. As such, in a general economic decline or recessionary climate, our assets may not generate sufficient cash to pay expenses, service debt, or cover maintenance costs, and, as a result, our results of operations and cash flows may be adversely affected. Factors that may adversely affect the economic performance and value of our properties include, among other things:

Uncertain economic conditions may adversely impact current tenants in our various markets and, accordingly, could affect their ability to pay rents owed to us pursuant to their leases. In periods of economic uncertainty, tenants are more likely to downsize and/or to declare bankruptcy; and, pursuant to various bankruptcy laws, leases may be rejected and thereby terminated. Furthermore, our ability to sell or lease our properties at favorable rates, or at all, may be negatively impacted by general or local economic conditions.

Our ability to collect rent from tenants may affect our ability to pay for adequate maintenance, insurance, and other operating costs (including real estate taxes). Also, the expense of owning and operating a property is not necessarily reduced when circumstances such as market factors cause a reduction in income from the property. If a property is mortgaged and we are unable to meet the mortgage payments, the lender could foreclose on the mortgage and take title to the property. In addition, interest rates, financing availability, law changes, and governmental regulations (including those governing usage, zoning, and taxes) may adversely affect our financial condition.

Impairment risks . We regularly review our real estate assets for impairment; and based on these reviews, we may record impairment losses that have an adverse effect on our results of operations. Negative or uncertain market and economic conditions, as well as market volatility, increase the likelihood of incurring impairment losses. If we decide to sell a real estate asset rather than holding it for long term investment or if we reduce our estimates of future cash flows on a real estate asset, the risk of impairment increases. The magnitude and frequency with which these charges occur could materially and adversely affect our business, financial condition, and results of operations.

Leasing risk . Our operating revenues are dependent upon entering into leases with, and collecting rents from, our tenants. Tenants whose leases are expiring may want to decrease the space they lease and/or may be unwilling to continue their lease. When leases expire or are terminated, replacement tenants may not be available upon acceptable terms and market rental rates may be lower than the previous contractual rental rates. Also, our tenants may approach us for additional concessions in order to remain open and operating. The granting of these concessions may adversely affect our results of operations and cash flows to the extent that they result in reduced rental rates, additional capital improvements, or allowances paid to, or on behalf of, the tenants.

Tenant and property concentration risk . As of December 31, 2017 , our top 20 tenants represented 31% of our annualized base rental revenues with no single tenant accounting for more tha n 6% of our annualized base rental revenues. The inability of any of our significant tenants to pay rent or a decision by a significant tenant to vacate their premises prior to, or at the conclusion of, their lease term could have a significant negative impact on our results of operations or financial condition if a suitable replacement tenant is not secured in a timely manner. These events could have a significant adverse impact on our results of operations or financial condition.

For the three months ended December 31, 2017 , 33.9% of our net operating income for properties owned as of December 31, 2017 was derived from the metropolitan Atlanta area, 22.4% was derived from the metropolitan Charlotte area, and 19.7% was derived from the metropolitan Austin area. Any adverse economic conditions impacting Atlanta, Charlotte, or Austin could adversely affect our overall results of operations and financial condition.

Uninsured losses and condemnation costs . Accidents, earthquakes, terrorism incidents, and other losses at our properties could adversely affect our operating results. Casualties may occur that significantly damage an operating property, and insurance proceeds may be less than the total loss incurred by us. Although we, or our joint venture partners where applicable, maintain casualty insurance under policies we believe to be adequate and appropriate, including rent loss insurance on operating properties, some types of losses, such as those related to the termination of longer-term leases and other contracts, generally are not insured. Certain types of insurance may not be available or may be available on terms that could result in large uninsured losses. Property ownership also involves potential liability to third parties for such matters as personal injuries occurring on the property. Such losses may not be fully insured. In addition to uninsured losses, various government authorities may condemn all or parts of operating properties. Such condemnations could adversely affect the viability of such projects.

Environmental issues . Environmental issues that arise at our properties could have an adverse effect on our financial condition and results of operations. Federal, state, and local laws and regulations relating to the protection of the environment may require a current or previous owner or operator of real estate to investigate and clean up hazardous or toxic substances or petroleum product releases at a property. If determined to be liable, the owner or operator may have to pay a governmental entity or third parties for property damage and for investigation and clean-up costs incurred by such parties in connection with the contamination, or perform such investigation and clean-up itself. Although certain legal protections may be available to prospective purchasers of property, these laws typically impose clean-up responsibility and liability without regard to whether the owner or operator knew of or caused the presence of the regulated substances. Even if more than one person may have been responsible for the release of regulated substances at the property, each person covered by the environmental laws may be held responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner or operator of a site for damages and costs resulting from regulated substances emanating from that site. We are not currently aware of any environmental liabilities at locations that we believe could have a material adverse effect on our business, assets, financial condition, or results of operations. Unidentified environmental liabilities could arise, however, and could have an adverse effect on our financial condition and results of operations.

Joint venture structure risks . Similar to other real estate companies, we have interests in various joint ventures (including partnerships and limited liability companies) and may in the future invest in real estate through such structures. Our venture partners may have rights to take actions over which we have no control, or the right to withhold approval of actions that we propose, either of which could adversely affect our interests in the related joint ventures, and in some cases, our overall financial condition and results of operations. These structures involve participation by other parties whose interests and rights may not be the same as ours. For example, a venture partner might have economic and/or other business interests or goals which are incompatible with our business interests or goals and that venture partner may be in a position to take action contrary to our interests. In addition, such venture partners may default on their obligations, which could have an adverse impact on the financial condition and operations of the joint venture. Such defaults may result in our fulfilling their obligations that may, in some cases, require us to contribute additional capital to the ventures. Furthermore, the success of a project may be dependent upon the expertise, business judgment, diligence, and effectiveness of our venture partners in matters that are outside our control. Thus, the involvement of venture partners could adversely impact the development, operation, ownership, financing, or disposition of the underlying properties.

Liquidity risk . Real estate investments are relatively illiquid and can be difficult to sell and convert to cash quickly. As a result, our ability to sell one or more of our properties, whether in response to any changes in economic or other conditions or in response to a change in strategy, may be limited. In the event we want to sell a property, we may not be able to do so in the desired time period, the sales price of the property may not meet our expectations or requirements, and we may be required to record an impairment loss on the property as a result.

Compliance or failure to comply with federal, state, and local regulatory requirements could result in substantial costs.

Our properties are subject to various federal, state, and local regulatory requirements, such as the Americans with Disabilities Act and state and local fire, health, and life safety requirements. Compliance with these regulations may involve upfront expenditures and/or ongoing costs. If we fail to comply with these requirements, we could incur fines or other monetary damages. We do not know whether existing requirements will change or whether compliance with existing or future requirements will require significant unanticipated expenditures that will affect our cash flows and results of operations.

Financing Risks

At certain times, interest rates and other market conditions for obtaining capital are unfavorable, and, as a result, we may be unable to raise the capital needed to invest in acquisition or development opportunities, maintain our properties, or otherwise satisfy our commitments on a timely basis, or we may be forced to raise capital at a higher cost or under restrictive terms, which could adversely affect returns on our investments, our cash flows, and results of operations.

We generally finance our acquisition and development projects through one or more of the following: our unsecured credit facility ("Credit Facility"), unsecured debt, non-recourse mortgages, construction loans, the sale of assets, joint venture equity, the issuance of common stock, and the issuance of units of CPLP. Each of these sources may be constrained from time to time because of market conditions, and the related cost of raising this capital may be unfavorable at any given point in time. These sources of capital, and the risks associated with each, include the following:

with the nature and amount of construction costs prior to funding, and require the lender to be satisfied with the level of pre-leasing prior to funding. Construction loans frequently require a portion of the loan to be recourse to us. In addition, construction loans generally require a completion guarantee by the borrower and may require a limited payment guarantee from the Company. There may be times when construction loans are not available, or are only available upon unfavorable terms, which could have an adverse effect on our ability to fund development projects or on our ability to achieve the returns we expect.

As a result of any additional indebtedness incurred to consummate investment activities, we may experience a potential material adverse effect on our financial condition and results of operations.

The incurrence of new indebtedness could have adverse consequences on our business, such as:

The impact of any of these potential adverse consequences could have a material adverse effect on our results of operations, financial condition, and liquidity.

Covenants contained in our Credit Facility, senior unsecured notes, term loans and mortgages could restrict our operational flexibility, which could adversely affect our results of operations.

Our Credit Facility, senior unsecured notes, and our unsecured term loan impose financial and operating covenants on us. These covenants may be modified from time to time, but covenants of this type typically include restrictions and limitations on our ability to incur debt, as well as limitations on the amount of our secured debt, unsecured debt and on the amount of joint venture activity in which we may engage. These covenants may limit our flexibility in making business decisions. If we fail to comply with these covenants, our ability to borrow may be impaired, which could potentially make it more difficult to fund our capital and operating needs. Our failure to comply with such covenants could cause a default, and we may then be required to repay our outstanding debt with capital from other sources. Under those circumstances, other sources of capital may not be available to us or may be available only on unattractive terms, which could materially and adversely affect our financial condition

and results of operations. In addition, the cross default provisions on the Credit Facility, senior unsecured notes, and term loan may affect business decisions on other debt.

Some of our mortgages contain customary negative covenants, including limitations on our ability, without the lender’s prior consent, to further mortgage that specific property, to enter into new leases, to modify existing leases, or to sell the property. Compliance with these covenants and requirements could harm our operational flexibility and financial condition.

Our degree of leverage could limit our ability to obtain additional financing or affect the market price of our securities.

Total debt as a percentage of either total asset value or total market capitalization and total debt as a multiple of annualized EBITDA is often used by analysts to gauge the financial health of equity REITs such as us. If our degree of leverage is viewed unfavorably by lenders or potential joint venture partners, it could affect our ability to obtain additional financing. In general, our degree of leverage could also make us more vulnerable to a downturn in business or the economy. In addition, increases in our debt to market capitalization ratio, which is in part a function of our stock price, or to other measures of asset value used by financial analysts may have an adverse effect on the market price of common stock.

Real Estate Acquisition and Development Risks

We face risks associated with operating property acquisitions.

Operating property acquisitions contain inherent risks. These risks may include:

In addition, we may acquire properties subject to liabilities with no or limited recourse against the prior owners or other third parties. As a result, if a liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle or contest it, which might not be fully covered by owner's title insurance policies or other insurance policies.

Any of these risks could cause a failure to realize the intended benefits of our acquisitions and could have a material adverse effect on our financial condition, results of operations, and the market price of our common stock.

We face risks associated with the development of real estate.

Development activities contain certain inherent risks. Although we seek to minimize risks from commercial development through various management controls and procedures, development risks cannot be eliminated. Some of the key factors affecting development of commercial property are as follows:

General Business Risks

We are dependent upon the services of certain key personnel, the loss of any of whom could adversely impact our ability to execute our business.

One of our objectives is to develop and maintain a strong management group at all levels. At any given time, we could lose the services of key executives and other employees. None of our key executives or other employees is subject to employment contracts. Further, we do not carry key person insurance on any of our executive officers or other key employees. The loss of services of any of our key employees could have an adverse effect upon our results of operations, financial condition, and our ability to execute our business strategy.

Our restated and amended articles of incorporation contain limitations on ownership of our stock, which may prevent a change in control that might otherwise be in the best interests of our stockholders.

Our restated and amended articles of incorporation impose limitations on the ownership of our stock. In general, except for certain individuals who owned stock at the time of adoption of these limitations, and except for persons or organizations that are granted waivers by our Board of Directors, no individual or entity may own more than 3.9% of the value of our outstanding stock. We provide waivers to this limitation on a case by case basis, which could result in increased voting control by a shareholder. The ownership limitation may have the effect of delaying, inhibiting, or preventing a transaction or a change in control that might involve a premium price for our stock or otherwise be in the best interest of our stockholders.

The market price of our common stock may fluctuate.

The market prices of shares of our common stock have been, and may continue to be, subject to fluctuation due to many events and factors such as those described in this report including:

Many of the factors listed above are beyond our control. Those factors may cause market prices of shares of our common stock to decline, regardless of our financial performance, condition, and prospects. The market price of shares of our common stock may fall significantly in the future, and it may be difficult for our stockholders to resell our common stock at prices they find attractive.

If our future operating performance does not meet the projections of our analysts or investors, our stock price could decline.

Independent securities analysts publish quarterly and annual projections of our financial performance. These projections are developed independently by third-party securities analysts based on their own analyses, and we undertake no obligation to monitor, and take no responsibility for, such projections. Such estimates are inherently subject to uncertainty and should not be relied upon as being indicative of the performance that we anticipate for any applicable period. Our actual revenues, net income, and funds from operations may differ materially from what is projected by securities analysts. If our actual results do not meet analysts’ guidance, our stock price could decline significantly.

We face risks associated with security breaches through cyber attacks, cyber intrusions, or otherwise, as well as other significant disruptions of our information technology (IT) networks and related systems.

We face risks associated with security breaches or disruptions, whether through cyber attacks or cyber intrusions over the internet, malware, computer viruses, attachments to emails, persons inside our organization, or persons with access to systems inside our organization, and other significant disruptions of our IT networks and related systems. The risk of a security breach or disruption, particularly through cyber attacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity, and sophistication of attempted attacks and intrusions from

around the world have increased. Our IT networks and related systems are essential to the operation of our business and our ability to perform day-to-day operations (including managing our building systems) and, in some cases, may be critical to the operations of certain of our tenants. There can be no assurance that our efforts to maintain the security and integrity of these types of IT networks and related systems will be effective or that attempted security breaches or disruptions would not be successful or damaging. A security breach or other significant disruption involving our IT networks and related systems could adversely impact our financial condition, results of operations, cash flows, liquidity, and the market price of our common stock.

Federal Income Tax Risks

Any failure to continue to qualify as a REIT for federal income tax purposes could have a material adverse impact on us and our stockholders.

We intend to continue to operate in a manner to qualify as a REIT for federal income tax purposes. Qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code (the “Code”), for which there are only limited judicial or administrative interpretations. Certain facts and circumstances not entirely within our control may affect our ability to qualify as a REIT. In addition, we can provide no assurance that legislation, new regulations, administrative interpretations, or court decisions will not adversely affect our qualification as a REIT or the federal income tax consequences of our REIT status.

If we were to fail to qualify as a REIT, we would not be allowed a deduction for distributions to stockholders in computing our taxable income. In this case, we would be subject to federal income tax on our taxable income at regular corporate rates. Unless entitled to relief under certain Code provisions, we also would be disqualified from operating as a REIT for the four taxable years following the year during which qualification was lost. As a result, we would be subject to federal and state income taxes which could adversely affect our results of operations and distributions to stockholders. Although we currently intend to operate in a manner designed to qualify as a REIT, it is possible that future economic, market, legal, tax, or other considerations may cause us to revoke the REIT election.

In order to qualify as a REIT, under current law, we generally are required each taxable year to distribute to our stockholders at least 90% of our net taxable income (excluding any net capital gain). To the extent that we do not distribute all of our net capital gain or distribute at least 90%, but less than 100%, of our other taxable income, we are subject to tax on the undistributed amounts at regular corporate rates. In addition, we are subject to a 4% nondeductible excise tax to the extent that distributions paid by us during the calendar year are less than the sum of the following:

We generally intend to make distributions to our stockholders to comply with the 90% distribution requirement to avoid corporate-level tax on undistributed taxable income and to avoid the nondeductible excise tax. Distributions could be made in cash, stock or in a combination of cash and stock. Differences in timing between taxable income and cash available for distribution could require us to borrow funds to meet the 90% distribution requirement, to avoid corporate-level tax on undistributed taxable income, and to avoid the nondeductible excise tax.

Certain property transfers may be characterized as prohibited transactions.

From time to time, we may transfer or otherwise dispose of some of our properties. Under the Code, any gains resulting from transfers or dispositions, from other than a taxable REIT subsidiary, that are deemed to be prohibited transactions would be subject to a 100% tax on any gain associated with the transaction. Prohibited transactions generally include sales of assets that constitute inventory or other property held for sale to customers in the ordinary course of business. Since we acquire properties primarily for investment purposes, we do not believe that our occasional transfers or disposals of property are deemed to be prohibited transactions. However, whether or not a transfer or sale of property qualifies as a prohibited transaction depends on all the facts and circumstances surrounding the particular transaction. The Internal Revenue Service may contend that certain transfers or disposals of properties by us are prohibited transactions. While we believe that the Internal Revenue Service would not prevail in any such dispute, if the Internal Revenue Service were to argue successfully that a transfer or disposition of property constituted a prohibited transaction, we would be required to pay a tax equal to 100% of any gain allocable to us from the prohibited transaction. In addition, income from a prohibited transaction might adversely affect our ability to satisfy the income tests for qualification as a REIT for federal income tax purposes.

We may face risks in connection with Section 1031 exchanges.

If a transaction's gain that is intended to qualify as a Section 1031 deferral is later determined to be taxable, we may face adverse consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of properties on a tax-deferred basis.

Recent changes to the U.S. tax laws could have a negative impact on real estate in general and our business operations, financial condition and earnings.

An act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018 commonly known as Tax Cuts and Jobs Act (the "Act"), which generally takes effect for taxable years beginning on or after January 1, 2018 (subject to certain exceptions), makes many significant changes to the U.S. federal income tax laws that will profoundly impact the taxation of individuals and corporations (including both regular C corporations and corporations that have elected to be taxed as REITs). A number of changes that affect noncorporate taxpayers will expire at the end of 2025 unless Congress acts to extend them. These changes will impact us and our shareholders in various ways, some of which are adverse or potentially adverse compared to prior law. To date, the IRS has issued only limited guidance with respect to certain of the new provisions, and there are numerous interpretive issues that will require guidance. It is highly likely that technical corrections legislation will be needed to clarify certain aspects of the new law and give proper effect to Congressional intent. There can be no assurance, however, that technical clarifications or changes needed to prevent unintended or unforeseen tax consequences will be enacted by Congress in the near future. Additional changes to tax laws are likely to continue to occur in the future, and we cannot assure investors that any such changes will not adversely affect the taxation of our stockholders. Any such changes could have an adverse effect on an investment in shares or on the market value or the resale potential of our properties. Investors are urged to consult with their own tax advisor with respect to the impact of recent legislation on ownership of shares and the status of legislative, regulatory, or administrative developments and proposals, and their potential effect on ownership of shares.

Disclosure Controls and Internal Control over Financial Reporting Risks

Our business could be adversely impacted if we have deficiencies in our disclosure controls and procedures or internal control over financial reporting.

The design and effectiveness of our disclosure controls and procedures and internal control over financial reporting may not prevent all errors, misstatements, or misrepresentations. While management will continue to review the effectiveness of our disclosure controls and procedures and internal control over financial reporting, there can be no guarantee that our internal control over financial reporting will be effective in accomplishing all control objectives at all times. Deficiencies, including any material weakness, in our internal control over financial reporting which may occur in the future could result in misstatements of our results of operations, restatements of our financial statements, a decline in our stock price, or otherwise materially adversely affect our business, reputation, results of operations, financial condition, or liquidity.

Not applicable.
