COMPANY PROFILE

The Company

Boston Properties, Inc. (“Boston Properties,” “BXP” or the “Company”), a self-administered and self-managed real estate investment trust (REIT), is one of the largest owners, managers, and developers of first-class office properties in the United States, with a significant presence in five markets: Boston, Los Angeles, New York, San Francisco, and Washington, DC. The Company was founded in 1970 by Mortimer B. Zuckerman and Edward H. Linde in Boston, where it maintains its headquarters. Boston Properties became a public company in June 1997. Boston Properties is a fully integrated real estate investment trust that develops, redevelops, acquires, manages, operates and owns a diverse portfolio of primarily Class A office space totaling 47.7 million square feet and consisting of 164 office properties (including six properties under construction), five retail properties, four residential properties (including two properties under construction/redevelopment) and one hotel. Boston Properties is well-known for itsin-house building management expertise and responsiveness to tenants’ needs. The Company holds a superior track record in developing premium Central Business District (CBD) office buildings, successfulmixed-use complexes, suburban office centers andbuild-to-suit projects for the U.S. government and a diverse array of creditworthy tenants.

Management

Boston Properties’ senior management team is among the most respected and accomplished in the REIT industry. Our deep and talented team of 35 individuals averages 30 years of real estate experience and 19 years with Boston Properties. We believe that our size, management depth, financial strength, reputation, and relationships of key personnel provide a competitive advantage to realize growth through property development and acquisitions. Boston Properties benefits from the reputation and relationships of key personnel, including Owen D. Thomas, Chief Executive Officer; Douglas T. Linde, President; Raymond A. Ritchey, Senior Executive Vice President; and Michael E. LaBelle, Executive Vice President, Chief Financial Officer and Treasurer. Our senior management team’s national reputation helps us attract business and investment opportunities. In addition, our other executive officers that serve as Regional Managers have strong reputations that assist in identifying and closing on new opportunities, having opportunities brought to us, and in negotiating with tenants andbuild-to-suit prospects. Additionally, Boston Properties’ Board of Directors consists of 11 distinguished members, the majority of whom are Independent Directors.

Strategy

Boston Properties’ primary business objective is to maximize return on investment in an effort to provide its investors with the greatest possible total return in all points of the economic cycle. To achieve this objective, the Company maintains consistent strategies that include the following:

• concentrating on carefully targeted markets characterized by high barriers to the creation of new supply and strong real estate fundamentals where tenants have demonstrated a preference for high-quality office buildings and other facilities - currently Boston, Los Angeles, New York, San Francisco and Washington, DC;

• investing in the highest quality buildings (primarily office) that are able to maintain high occupancy and achieve premium rental rates through economic cycles;

• in our core markets, maintaining scale and a full service real estate capability (leasing, development, construction and property management) to ensure we (1) see all relevant investment deal flow and (2) maintain an ability to execute on all types of real estate opportunities, such as acquisitions, dispositions, repositioning and development, throughout the real estate investment cycle;

• be astute in market timing for investment decisions by acquiring properties in times of opportunity, developing into economic growth and selectively selling assets to either take advantage of the demand for our premier properties or pare from the portfolio properties that we believe have slower future growth potential, resulting in continuous portfolio refreshment;

• taking on complex, technically-challenging development projects that leverage the skills of our management team to successfully develop, acquire, and reposition properties;

• exploring joint-venture opportunities with partners who seek to benefit from our depth of development and management expertise;

• ensuring a strong balance sheet to maintain consistent access to capital and the resultant ability to make opportunistic investments; and

• fostering a culture and reputation of integrity and fair dealing, making us the counterparty of choice for tenants and real estate industry participants.

FOURTH QUARTER 2016

GUIDANCE

The Company’s guidance for the first quarter 2017 and full year 2017 for diluted earnings per common share attributable to Boston Properties, Inc. common shareholders (“EPS”) and diluted funds from operations (“FFO”) per common share attributable to Boston Properties, Inc. common shareholders is set forth and reconciled below. Except as described below, the estimates reflect management’s view of current and future market conditions, including assumptions with respect to rental rates, occupancy levels and the earnings impact of the events referenced in the earnings release issued on January 31, 2017 and otherwise referenced during the Company’s conference call scheduled for February 1, 2017. The estimates do not include possible future gains or losses or the impact on operating results from other possible future property acquisitions or dispositions, other possible capital markets activity or possible future impairment charges. EPS estimates may be subject to fluctuations as a result of several factors, including changes in the recognition of depreciation and amortization expense and any gains or losses associated with disposition activity. The Company is not able to assess at this time the potential impact of these factors on projected EPS. By definition, FFO does not include real estate-related depreciation and amortization, impairment losses on depreciable real estate or gains or losses associated with disposition activities. For a complete definition of FFO and statements of the reasons why management believes it provides useful information to investors, see page 48. There can be no assurance that the Company’s actual results will not differ materially from the estimates set forth below.

(3) Consists of lease transaction costs that qualify as rent inducements in accordance with GAAP. Lease transaction costs are generally included in 2nd generation tenant improvements and leasing commissions.

(4) Represents the net adjustment for above- and below-market leases that are being amortized over the terms of the respective leases in place at the property acquisition dates.

(5) The Company believes that the presentation of its Interest Coverage Ratio provides investors with useful information about the Company’s financial condition because it measures the margin it has for paying interest expense as of a certain date. In addition, by analyzing interest coverage ratios over a period of time, trends may emerge that provide investors a better sense of whether a company’s financial condition is improving or worsening. The ratios may also be used to compare the ability of different companies to meet their interest expense obligations, which can help when making an investment decision. The Company presents its Interest Coverage Ratio in two ways - including capitalized interest and excluding capitalized interest. GAAP requires the capitalization of interest expense during development. Therefore, for a company like Boston Properties, Inc. that is an active developer of real estate, presenting the Interest Coverage Ratio (excluding capitalized interest) provides an alternative measure of financial condition that may be more indicative of the Company’s ability to meet its interest expense obligations.

FOURTH QUARTER 2016

SENIOR UNSECURED DEBT COVENANT COMPLIANCE RATIOS

(dollars in thousands)

In the fourth quarter of 2002, the Company’s Operating Partnership (Boston Properties Limited Partnership) received investment grade ratings on its senior unsecured debt securities and thereafter issued unsecured notes. The notes were issued under an indenture, dated as of December 13, 2002, by and between Boston Properties Limited Partnership and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented from time to time (the “Indenture”), which, among other things, requires us to comply with the following limitations on incurrence of debt: Limitation on Outstanding Debt; Limitation on Secured Debt; Ratio of Annualized Consolidated EBITDA to Annualized Interest Expense; and Maintenance of Unencumbered Assets. Compliance with these restrictive covenants requires us to apply specialized terms the meanings of which are described in detail in our filings with the SEC, and to calculate ratios in the manner prescribed by the Indenture.

This section presents such ratios as of December 31, 2016 to show that the Company’s Operating Partnership was in compliance with the terms of the Indenture, which has been filed with the SEC. Management is not presenting these ratios and the related calculations for any other purpose or for any other period, and is not intending for these measures to otherwise provide information to investors about the Company’s financial condition or results of operations. Investors should not rely on these measures other than for purposes of testing our compliance with the Indenture. This section also presents certain other indenture-related data that we believe assists investors in evaluating the Company’s unsecured debt securities.

(1) Includes 100% share of consolidated joint ventures. Same Property consolidated joint venture properties includes 767 Fifth Avenue (The GM Building), 601 Lexington Avenue (excluding the portion removed from the complex as part of a planned redevelopment) and Times Square Tower in New York City and 100 Federal Street and Atlantic Wharf Office Building in Boston, MA.

(2) Rental Revenue (excluding termination income) is used internally by the Company as a performance measure and provides investors with additional information regarding operating performance at a property level that allows them to compare operating performance between periods without taking into account termination income, which can distort the results for any given period because they generally represent multiple months or years of a tenant’s rental obligations that are paid in a lump sum in connection with a negotiated early termination of the tenant’s lease and are not reflective of the core ongoing operating performance of the Company’s properties.

(3) For a quantitative reconciliation of net income attributable to Boston Properties, Inc. common shareholders to net operating income (NOI) (excluding termination income), see page 21. For disclosures relating to the Company’s use of NOI, see page 48.

FOURTH QUARTER 2016

DEFINITIONS

This section contains definitions of certainnon-GAAP financial measures and other terms that the Company uses in this supplemental package and, where applicable, the reasons why management believes thesenon-GAAP financial measures provide useful information to investors about the Company’s financial condition and results of operations and the other purposes for which management uses the measures. Additional detail can be found in the Company’s most recent annual report on Form10-K and quarterly report on Form10-Q, as well as other documents filed with or furnished to the SEC from time to time.

The Company also presents certain of these measures (1) on a “Combined” basis, which is defined as the consolidated amount, plus the Company’s share of the measure from its unconsolidated joint ventures (calculated based upon the Company’s percentage ownership interest), and (2) showing “BXP’s Share” of the Combined amount, which is defined as the Combined amount, minus the Company’s partners’ share of the amount from its consolidated joint ventures (calculated based upon the partners’ percentage ownership interests). Management believes that the “Combined” measures provide useful information to investors regarding the Company’s financial condition and/or results of operations because they include the Company’s share of the applicable amount from unconsolidated joint ventures and, for “BXP’s Share” of the Combined amount, exclude the Company’s partners’ share from consolidated joint ventures, in each case presented on the same basis. The Company has several significant joint ventures and presenting various financial measures in this manner can help investors better understand the Company’s financial condition and/or results of operations after taking into account its economic interest in these joint ventures. The Company cautions investors that the ownership percentages used in calculating “Combined” amounts and “BXP’s Share” of any Combined amounts may not completely and accurately depict all of the legal and economic implications of holding an interest in a consolidated or unconsolidated joint venture. For example, in addition to partners’ interests in profits and capital, partnership agreements vary in the allocation of rights regarding decision making (both routine and major decisions), distributions, transferability of interests, liquidations, etc. As a result, presentations of measures on a Combined basis and showing BXP’s Share of the Combined amount should be considered with and as a supplement to the Company’s financial information presented in accordance with GAAP.

Annualized Rental Obligations

Annualized Rental Obligations is defined as Rental Obligations at the end of the reporting period, multiplied by twelve (12).

Average Economic Occupancy

Average Economic Occupancy is defined as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue is determined by valuing average occupied units at contract rates and average vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant units at their Market Rents, Average Economic Occupancy takes into account the fact that units of different sizes and locations within a residential property have different economic impacts on a residential property’s total possible gross revenue.

Average Monthly Rental Rates

Average Rental Rates are calculated by the Company as rental revenue in accordance with GAAP, divided by the weighted monthly average number of occupied units.

Average Physical Occupancy

Average Physical Occupancy is defined as the average number of occupied units divided by the total number of units, expressed as a percentage.

Debt to Market Capitalization Ratio

Consolidated Debt to Consolidated Market Capitalization Ratio is defined as consolidated debt as a percentage of the market value of the Company’s outstanding equity securities plus the Company’s consolidated debt, and it is a measure of leverage commonly used by analysts in the REIT sector. Consolidated Market Capitalization is the sum of (A) the Company’s consolidated debt plus (B) the market value of the Company’s outstanding equity securities calculated using the closing price per share of common stock of the Company, as reported by the New York Stock Exchange, multiplied by the sum of (1) outstanding shares of common stock of the Company, (2) outstanding common units of limited partnership interest in Boston Properties Limited Partnership (excluding common units held by the Company), (3) common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, (4) on and after February 6, 2015, which was the end of the performance period for 2012 OPP Units and thus the date earned, common units issuable upon conversion of 2012 OPP Units that were issued in the form of LTIP Units and (5) on and after February 4, 2016, which was the end of the performance period for 2013 MYLTIP Units and thus the date earned, common units issuable upon conversion of 2013 MYLTIP Units that were issued in the form of LTIP Units plus (C) outstanding shares of 5.25% Series B Cumulative Redeemable Preferred Stock multiplied by their fixed liquidation preference of $2,500 per share. The calculation of Consolidated Market Capitalization does not include LTIP Units issued in the form of MYLTIP Awards unless and until certain performance thresholds are achieved and they are earned. Because their three-year performance periods have not yet ended, 2014, 2015 and 2016 MYLTIP Units are not included. The Company also presentsBXP’s Share of Combined Market Capitalization, which is calculated in a similar manner, except that BXP’s Share of Combined Debt is utilized instead of the Company’s consolidated debt in both the numerator and the denominator. The Company presents these ratios because its degree of leverage could affect its ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes and because different investors and lenders consider one or both of these ratios. Investors should understand that these ratios are, in part, a function of the market price of the common stock of the Company, and as such will fluctuate with changes in such price and does not necessarily reflect the Company’s capacity to incur additional debt to finance its activities or its ability to manage its existing debt obligations. However, for a company like Boston Properties, Inc., whose assets are primarily income-producing real estate, these ratios may provide investors with an alternate indication of leverage, so long they are evaluated along with the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of the Company’s outstanding indebtedness.

Funds Available for Distribution (FAD) and FAD Payout Ratio

In addition to FFO, the Company presents Funds Available for Distribution to common shareholders and common unitholders (FAD), which is anon-GAAP financial measure that is calculated by (1) adding to FFO lease transaction costs that qualify as rent inducements,non-real estate depreciation,non-cash losses (gains) from early extinguishments of debt, stock-based compensation expense, partners’ share of consolidated and unconsolidated joint venture 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences) and unearned portion of capitalized fees, (2) eliminating the effects of straight-line rent, straight-line ground rent expense adjustment, fair value interest adjustment and fair value lease revenue, and (3) subtracting maintenance capital expenditures, hotel improvements, equipment upgrades and replacements, 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences),non-cash termination income adjustment (fair value lease amounts) and impairments ofnon-depreciable real estate. The Company believes that the presentation of FAD provides useful information to investors regarding the Company’s results of operations because FAD provides supplemental information regarding the Company’s operating performance that would not otherwise be available and may be useful to investors in assessing the Company’s operating performance. Additionally, although the Company does not consider FAD to be a liquidity measure, as it does not make adjustments to reflect changes in working capital or the actual timing of the payment of income or expense items that are accrued in the period, the Company believes that FAD may provide investors with useful supplemental information regarding the Company’s ability to generate cash from its operating performance and the impact of the Company’s operating performance on its ability to make distributions to its shareholders. Furthermore, the Company believes that FAD is frequently used by analysts, investors and other interested parties in the evaluation of its performance as a REIT and, as a result, by presenting FAD the Company is assisting these parties in their evaluation. FAD should not be considered as a substitute for net income (loss) attributable to Boston Properties, Inc.‘s common shareholders determined in accordance with GAAP or any other GAAP financial measures and should only be considered together with and as a supplement to the Company’s financial information prepared in accordance with GAAP.

FAD Payout Ratio is defined as distributions to common shareholders and unitholders (excluding any special distributions) divided by FAD.

FOURTH QUARTER 2016

DEFINITIONS (continued)

Funds from Operations (FFO)

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), the Company calculates Funds from Operations, or “FFO,” by adjusting net income (loss) attributable to Boston Properties, Inc. common shareholders (computed in accordance with GAAP) for gains (or losses) from sales of properties, impairment losses on depreciable real estate consolidated on the Company’s balance sheet, impairment losses on its investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures, real estate-related depreciation and amortization, and the Company’s share of income (loss) from unconsolidated partnerships and joint ventures. FFO is anon-GAAP financial measure, but the Company believes the presentation of FFO, combined with the presentation of required GAAP financial measures, has improved the understanding of operating results of REITs among the investing public and has helped make comparisons of REIT operating results more meaningful. Management generally considers FFO and FFO per share to be useful measures for understanding and comparing the Company’s operating results because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment losses and real estate asset depreciation and amortization (which can differ across owners of similar assets in similar condition based on historical cost accounting and useful life estimates), FFO and FFO per share can help investors compare the operating performance of a company’s real estate across reporting periods and to the operating performance of other companies.

The Company’s computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently. In order to facilitate a clear understanding of the Company’s operating results, FFO should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders as presented in the Company’s consolidated financial statements. FFO should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to the Company’s financial information prepared in accordance with GAAP.

In-Service Properties

The Company treats a property as being“in-service” upon the earlier of(1) lease-up and completion of tenant improvements or (2) one year after cessation of major construction activity as determined under GAAP. The determination as to when an entire property should be treated as“in-service” involves a degree of judgment and is made by management based on the relevant facts and circumstances of the particular property. For portfolio operating and occupancy statistics, the Company specifies a single date for treating a property as“in-service,” which is generally later than the date the property is partially placedin-service under GAAP. Under GAAP, a property may be placedin-service in stages as construction is completed and the property is held available for occupancy. In accordance with GAAP, when a portion of a property has been substantially completed and either occupied or held available for occupancy, the Company ceases capitalizing costs on that portion, even though it may not treat the property as being“in-service,” and continues to capitalize only those costs associated with the portion still under construction.In-service properties include properties held by the Company’s unconsolidated joint ventures.

Market Rents

Market Rents used by the Company in calculating Average Economic Occupancy are based on the current market rates set by the managers of the Company’s residential properties based on their experience in renting their residential property’s units and publicly available market data. Trends in market rents for a region as reported by others could vary. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Net Operating Income (NOI)

Net operating income (NOI) is anon-GAAP financial measure equal to net income attributable to Boston Properties, Inc. common shareholders, the most directly comparable GAAP financial measure, plus (1) preferred dividends, net income attributable to noncontrolling interests, corporate general and administrative expense, transaction costs, depreciation and amortization, interest expense and losses from early extinguishments of debt, less (2) gains on sales of real estate, development and management services income, income from unconsolidated joint ventures, gain on sale of investment in unconsolidated joint venture, interest and other income and gains from investments in securities. In some cases the Company also presents (1) NOI – cash basis, which is NOI after eliminating the effects of straight-lining of rent, fair value lease revenue, ground rent expense, and lease transaction costs that qualify as rent inducements in accordance with GAAP and (2) NOI and NOI – cash basis, in each case excluding termination income.

The Company uses these measures internally as performance measures and believes they provide useful information to investors regarding the Company’s results of operations and financial condition because, when compared across periods, they reflect the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. Presenting NOI – cash allows investors to compare NOI performance across periods without taking into account the effect of certainnon-cash rental revenues and ground rent expenses. Similar to depreciation and amortization, fair value lease revenues, because of historical cost accounting, may distort operating performance measures at the property level. Additionally, presenting NOI excluding the impact of the straight-lining of rent provides investors with an alternative view of operating performance at the property level that more closely reflects net cash generated at the property level on an unleveraged basis. Presenting NOI measures that exclude termination income provides investors with additional information regarding operating performance at a property level that allows them to compare operating performance between periods without taking into account termination income, which can distort the results for any given period because they generally represent multiple months or years of a tenant’s rental obligations that are paid in a lump sum in connection with a negotiated early termination of the tenant’s lease and are not reflective of the core ongoing operating performance of the Company’s properties.

Rental Obligations

Rental Obligations is defined as the contractual base rents (but excluding percentage rent) and budgeted reimbursements from tenants under existing leases. These amounts exclude rent abatements.

Same Properties

In the Company’s analysis of NOI, particularly to make comparisons of NOI between periods meaningful, it is important to provide information for properties that werein-service and owned by the Company throughout each period presented. The Company refers to properties acquired or placedin-service prior to the beginning of the earliest period presented and owned by the Company through the end of the latest period presented as “Same Properties.” “Same Properties” therefore exclude properties placedin-service, acquired, repositioned or in development or redevelopment after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented. Accordingly, it takes at least one year and one quarter after a property is acquired or treated as“in-service” for that property to be included in “Same Properties.” Pages27-29 indicate by footnote the“In-Service Properties” that are not included in “Same Properties.”
