REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Participants of

Tiffany & Co. Employee Profit Sharing

and Retirement Savings Plan

We have audited the accompanying statements of net assets available for benefits of Tiffany & Co. Employee Profit Sharing and Retirement Savings Plan (the “Plan”) as of January 31, 2013 and 2012, and the related statement of changes in net assets available for benefits for the year ended January 31, 2013. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of Tiffany & Co. Employee Profit Sharing and Retirement Savings Plan as of January 31, 2013 and 2012, and the changes in its net assets available for benefits for the year ended January 31, 2013, in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

EMPLOYEE PROFIT SHARING AND RETIREMENT SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

The following description of the Tiffany & Co. Employee Profit Sharing and Retirement Savings Plan (the “Plan”) is provided for general informational purposes only. Participants should refer to the Summary Plan Description or the Plan document for complete information.

General

The Plan is a defined contribution plan covering all eligible employees of Tiffany & Co. (the “Company”) and its U.S. subsidiaries and has an employee profit-sharing feature (“ESOP”). Effective February 1, 2006, the Plan was amended to provide a defined contribution retirement benefit (the “DCRB”) to eligible employees hired on or after January 1, 2006.

The assets of the Plan are maintained and transactions therein are executed by DWS Trust Company, Inc., the trustee of the Plan (“Trustee”), an affiliate of Deutsche Bank, Inc. The Plan record keeper is ADP Retirement Services. The Plan is administered by the Employee Profit Sharing and Retirement Savings Plan Committee (“Plan Committee”) appointed by the Board of Directors of the Company. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

Eligibility

Employees automatically become participants in the ESOP feature of the Plan on the February 1^st immediately following their initial date of employment. Employees become eligible and are automatically enrolled in the 401(k) feature 60 days after their initial date of employment provided the employee is scheduled to work thirty-five or more hours per week on a non-temporary basis. All other employees are enrolled 60 days after completing one year of service. Employees may opt out of 401(k) participation at any time. All employees hired on or after January 1, 2006 automatically become participants in the DCRB feature of the Plan on their date of hire. Officers of the Company (those subject to Section 16 of the Securities Exchange Act of 1934) do not share in contributions made under the ESOP feature of the Plan.

Contributions

The ESOP feature of the Plan is non-contributory on the part of participating employees and is funded by Company contributions of shares of Tiffany & Co. common stock. Employees who have two or more years of service can diversify his or her ESOP contribution into other investment options provided under the Plan. Company contributions to the ESOP, if any, are based upon the achievement by the Company of certain targeted earnings objectives as established by the Board of Directors of the Company in accordance with, and subject to, the terms and limitations of the Plan. Employees must be employed by the Company on the last day of the Plan year and have at least 1,000 hours of employment during the Plan year to receive the ESOP contribution. As of January 31, 2013, the Company did not have an ESOP contribution payable. As of January 31, 2012, the Company had an ESOP contribution payable of $3,149,977, of which $429,949 was considered non-participant directed.

The 401(k) feature of the Plan is funded by both employee and employer contributions. With respect to employee contributions, participants may elect, in one percent increments, to have an amount of between one (1) and, beginning in 2012, fifty (50) percent of their annual compensation, not to exceed $17,000 in 2012 (or $22,500 for individuals over 50 years of age), subject to an annual inflation adjustment,

contributed to the 401(k) feature of the Plan as a tax deferred contribution, subject to certain limitations applicable to highly compensated employees.

Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans.

With respect to employer contributions, following the end of each Plan year, a contribution may be made at the discretion of the Company to the account of each employee who was a participant in the 401(k) feature of the Plan as of the end of such Plan year. Such contribution for the Plan years ended on January 31, 2013 and 2012 is equal to up to fifty percent (50%) of such participant’s total contributions to his or her account during that year, up to a maximum of six percent (6%) of such participant’s compensation over that same year. Employer contributions to a participant’s account are allocated among the various investment options in the same proportion as the participant’s own contributions.

Under certain circumstances, employee contributions and employer matching contributions may be limited in the case of highly compensated employees.

The DCRB feature of the Plan is non-contributory on the part of participating employees and is funded by employer contributions, following the end of each Plan year, to be invested in a manner similar to the 401(k) retirement savings portion of the Plan. Employer contributions are determined by a formula using the participant’s eligible compensation, age and years of service.

Participant Accounts

Each participant’s 401(k) and DCRB account is credited with the participant’s contribution, if applicable, employer contributions, and an allocation of each selected fund’s earnings, including interest, dividends and net realized and unrealized appreciation in the fair value of investments. Each participant’s account is also charged an allocation of net realized and unrealized depreciation in the fair value of investments and investment-related expenses. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account balance. Allocations are based on participant account balances.

The Company’s contribution for each Plan year under the ESOP feature of the Plan is allocated to participants’ accounts on an equal basis.

Vesting

All amounts contributed by employees under the 401(k) feature of the Plan and earnings thereon are immediately 100% vested and non-forfeitable at all times. Employer contributions under the 401(k) feature of the Plan become 100% vested and non-forfeitable after the participant has completed two years of service. Employer contributions under the DCRB feature of the Plan become vested based on the following schedule:

Contributions to participant accounts associated with the ESOP feature of the Plan become 100% vested and non-forfeitable when the participant has completed two years of service. A participant also becomes vested in his or her ESOP account and employer matching contributions upon termination of employment by reason of death, retirement or disability. A participant becomes vested in his or her DCRB employer contributions upon termination of employment by reason of death or if employment with the Company

ends at or after age 65. For purposes of the Plan, retirement is defined as termination of employment after age 65.

In the event a participant leaves the Company prior to becoming fully vested, the participant will forfeit the shares in his or her ESOP account and such shares will remain in the Plan to be reallocated ratably amongst the remaining participants in the Plan’s ESOP feature within the DWS Trust Co. Money Market Prime Series. Forfeitures relating to the ESOP feature of the Plan totaled $54,694 and $136,063 at January 31, 2013 and 2012, respectively and were subsequently reallocated. The participant will also forfeit any assets in his or her 401(k) or DCRB account representing unvested employer contributions and such assets will be made available to offset future employer matching contributions to other participants’ accounts. Forfeitures of contributions in the 401(k) and DCRB portion of the Plan totaled $692,018 and $591,804 at January 31, 2013 and 2012, respectively. Forfeitures of $525,280 and $253,654 were used to reduce employer contributions, which are made in the following year, for the years ended January 31, 2013 and 2012, respectively.

Administrative Expenses

The Plan accrues a percentage of the fair value of the Plan assets which is transferred into a holding account to pay recordkeeping fees and other administrative expenses as they come due. Tiffany and Company must pay any expenses which exceed amounts accumulated in the holding account.

Notes Receivable from Participants and Withdrawals

Participants may borrow from their 401(k) accounts up to a maximum amount of no more than $50,000 or fifty percent (50%) of their total vested 401(k) account balance including employer matching contributions. The Plan permits each participant to undertake up to two loans simultaneously. All loans must be repaid within five years unless they are used by the participant to purchase a primary residence. Loans are collaterized by the balance in the participant’s account and bear interest at rates commensurate with prevailing market rates as determined by the Plan administrator. Interest rates currently range from 4.25 percent to 9.25 percent. Principal and interest is paid ratably through payroll deductions.

Participants may also obtain a cash withdrawal of all or a portion of the value of their 401(k) account contributions (excluding employer matching contributions and earnings on contributions) and their rollover contributions, if any, on the basis of hardship as permitted under the Plan.

Payment of Benefits

Distributions of the participant’s account may be made upon retirement, death or disability, or upon termination of employment. Participants will receive the full vested balance of their Plan account in a lump sum cash distribution, except with respect to the DCRB account which may be received in the form of either a lump sum or ten substantially equal annual installments and with respect to whole shares held in the ESOP feature of the Plan that are distributed in the form of stock certificates. The balance of the participant’s Tiffany & Co. common stock fund account may also be distributed in the form of stock certificates for whole shares if the participant so elects. Subject to certain mandatory distribution provisions, in the event of retirement, a participant may elect to defer his/her distribution until the next Plan year thereby entitling the participant to his or her proportionate share of the Company’s contribution to the ESOP feature of the Plan for the Plan year in which the participant retired. In the event of a participant’s death, the distribution of the participant’s account balance will be made to the participant’s designated beneficiary or the participant’s estate, if no beneficiary has been so designated.

Voting Rights

Each participant is entitled to exercise voting rights attributable to the shares of Tiffany & Co. Common Stock allocated to his or her account and is notified by the Trustee prior to the time that such rights are to be exercised. The Trustee is not permitted to vote any allocated share for which instructions have not been given by a participant.

Table of Contents

Basis of Accounting

The Plan’s financial statements have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Payment of Benefits

Benefit payments to participants are recorded upon distribution.

New Accounting Standards

In May 2011, the Financial Accounting Standards Board issued a standard which clarifies existing fair value measurement and disclosure requirements, amends certain fair value measurement principles and requires additional disclosures about fair value measurements. The new standard was adopted by the Plan on February 1, 2012 and did not have a material impact on the Plan’s financial statements.

Investment Valuation

Investments in mutual funds are stated at fair value as determined by quoted market prices based on the net asset value of shares held by the Plan at year-end. Investments in Tiffany & Co. common stock are stated at fair value as determined by quoted market prices as of the last day of the Plan year. Investments in common and collective trusts are valued based on the net asset values (“NAV”) reported by the Trustee of the funds which are based on the value of the underlying assets owned by the fund, minus its liabilities and then divided by the number of shares outstanding. The NAV is used as a practical expedient to estimate fair value.

The Plan presents, in the statement of changes in net assets available for benefits, the net appreciation/(depreciation) in the fair value of its investments, which consists of the realized gains or losses and the unrealized appreciation/(depreciation) on those investments.

Income Recognition

Purchases and sales of investments are recorded on a trade date basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded when earned. Cost of securities sold is determined by specific identification method.

Notes Receivable from Participants

Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan document. Therefore, no allowance for credit losses has been recorded as of January 31, 2013 or 2012.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Investments that were equal to or exceeded 5% of the current value of the Plan’s net assets available for benefits at January 31, 2013 or 2012 were as follows:

As of January 31, 2013 and 2012, there were 958 shares totaling $63,005 and 944 shares totaling $60,196, respectively, of Tiffany & Co. common stock that were non-participant directed.

The net appreciation in the fair value of investments for the year ended January 31, 2013 was as follows:

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal market for the asset or liability in an orderly transaction between market participants on the measurement date. U.S. GAAP establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. U.S. GAAP prescribes three levels of inputs that may be used to measure fair value:

Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 1 inputs are considered to carry the most weight within the fair value hierarchy due to the low levels of judgment required in determining fair values.

Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3 – Unobservable inputs reflecting the reporting entity’s own assumptions. Level 3 inputs are considered to carry the least weight within the fair value hierarchy due to substantial levels of judgment required in determining fair value.

Table of Contents

Certain Plan investments include common and collective trusts and mutual funds managed by DWS Trust Company, Inc., the Plan Trustee. Therefore, investment transactions in such common and collective trusts and mutual funds are considered to be exempt party-in-interest transactions under the Department of Labor’s rules and regulations. Additionally, investments of the Plan include common stock of Tiffany & Co., the Plan sponsor.

The Internal Revenue Service (“IRS”) has determined and informed the Company by a letter dated January 12, 2012, that the Plan was designed and in conformity with the applicable requirements of the Internal Revenue Code. The Plan has since been amended. However, it is the belief of the Plan administrator and the Plan’s tax counsel that the Plan is currently designed and is being operated in compliance with the applicable requirements of the Internal Revenue Code. Accordingly, no provision for Federal income taxes has been made in the accompanying financial statements.

The Plan is subject to routine audits by taxing jurisdictions. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2009.

The Plan provides for various investment options in any one or a combination of Tiffany & Co. common stock, common and collective trusts and mutual funds that invest in a variety of stocks, bonds, fixed income securities and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.

Although it has not expressed any intent to do so, the Board of Directors of the Company reserves the right to change, amend or terminate the Plan at any time at its discretion, subject to the provisions of ERISA. In the event the Plan is terminated, participants will become 100% vested in their accounts. In addition, in the event of the dissolution, merger, consolidation or reorganization of the Company, unless the Plan is continued by a successor to the Company, the Plan will automatically terminate and the Plan’s assets will be liquidated.
