Prospectus Supplement Summary

        This summary contains basic information about us, our common stock and this offering. Because this is a summary, it does not contain all of the information you should consider before investing in our common stock. You should carefully read this summary together with the more detailed information and financial statements and notes thereto contained elsewhere or incorporated by reference in this prospectus supplement and the accompanying prospectus.

VENTAS

        We are a real estate investment trust ("REIT") with a geographically diverse portfolio of seniors housing and healthcare properties in the United States and Canada. As of September 30, 2011, our portfolio consisted of 1,361 properties: 673 seniors housing communities, 398 skilled nursing facilities, 47 hospitals and 243 medical office buildings ("MOBs") and other properties in 46 U.S. states, the District of Columbia and two Canadian provinces. We are a constituent member of the S&P 500® index, a leading indicator of the large cap U.S. equities market, with our headquarters located in Chicago, Illinois.

        Our primary business consists of acquiring and owning seniors housing and healthcare properties and leasing those properties to unaffiliated tenants or operating those properties through independent third-party managers. Through our Lillibridge subsidiary and our ownership interest in PMB Real Estate Services LLC, which we acquired in July 2011 in connection with our acquisition of NHP, we also provide management, leasing, marketing, facility development and advisory services to highly rated hospitals and health systems throughout the United States. In addition, from time to time, we make real estate loan and other investments relating to seniors housing and healthcare companies or properties.

        As of September 30, 2011, we leased 927 of our properties (excluding MOBs) to healthcare operating companies under "triple-net" or "absolute net" leases that obligate the tenants to pay all property-related expenses (including maintenance, utilities, repairs, taxes, insurance and capital expenditures), and we engaged independent third parties, such as Sunrise and Atria, to manage 199 of our seniors housing communities pursuant to long-term management agreements.

Underwriting

        Subject to the terms and conditions contained in an underwriting agreement among Ventas, Ventas Realty, the selling stockholders and Citigroup Global Markets Inc., as the underwriter, the selling stockholders have agreed to sell to the underwriter, and the underwriter has agreed to purchase from the selling stockholders, all of the shares of common stock offered by this prospectus supplement.

        Subject to the terms and conditions of the underwriting agreement, the underwriter has agreed to purchase from the selling stockholders 21,070,658 shares of common stock at a price of $53.45 per share.

        We and the selling stockholders have agreed to indemnify the underwriter against specified liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"), or to contribute to payments the underwriter may be required to make in respect of those liabilities.

        The underwriter is offering the shares, subject to prior sale, when, as and if offered to and accepted by the underwriter, subject to approval of legal matters by counsel and other conditions. The underwriter reserves the right to withdraw, cancel or modify this offer and to reject orders in whole or in part.

        The underwriter may receive from purchasers of the shares normal brokerage commissions in amounts agreed with such purchasers.

        The underwriter proposes to offer the shares of common stock offered hereby from time to time for sale in one or more transactions on the New York Stock Exchange, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt and acceptance by the underwriter and subject to the underwriter's right to reject any order in whole or in part. The underwriter may effect such transactions by selling the shares of common stock to or through dealers and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal. The difference between the price at which the underwriter purchases shares and the price at which the underwriter resells such shares, which may include a commission equivalent of up to $.05 per share, may be deemed underwriting compensation.

        The expenses of the offering, exclusive of the underwriting discount, are estimated at approximately $250,000 and are payable by us.

        Specifically, we and each of our executive officers have agreed, subject to certain exceptions, not to, directly or indirectly:

Table of Contents

        In addition, each selling stockholder, severally and not jointly, has agreed, subject to certain exceptions, not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Ventas common stock, or any options or warrants to purchase any Ventas common stock, or any securities convertible into, exchangeable for or that represent the right to receive Ventas common stock, whether now owned or hereinafter acquired, owned directly by such selling stockholder or with respect to which such selling stockholder has beneficial ownership, in each case, for 60 days after the date of this prospectus supplement without first obtaining the written consent of Citigroup Global Markets Inc.

        In the event that the selling stockholders notify the underwriter in writing that they do not intend to proceed with this offering, if the underwriting agreement does not become effective, or if the underwriting agreement is terminated prior to payment for and delivery of the common stock being offered hereby, the lockup provisions will be released.

NEW YORK STOCK EXCHANGE LISTING

        If the underwriter creates a short position in the common stock in connection with the offering, i.e., if the underwriter sells more shares than are listed on the cover of this prospectus supplement, the underwriter may reduce that short position by purchasing shares in the open market. Purchases of the common stock to stabilize its price or to reduce a short position may cause the price of the common stock to be higher than it might be in the absence of those purchases.

        Neither we nor the underwriter nor the selling stockholders make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock.

With the exception of our seniors housing communities that are managed by independent third parties, such as Sunrise, pursuant to long-term management agreements and certain of our MOBs, including those acquired in connection with our Lillibridge acquisition, we lease our properties to healthcare operating companies under "triple-net" or "absolute-net" leases, which require the tenants to pay all property-related expenses. We also had real estate loan and other investments relating to seniors housing and healthcare companies as of March 31, 2011.

        Our primary business consists of acquiring, financing and owning seniors housing and healthcare properties and leasing those properties to third parties or operating those properties through independent third-party managers. Through our Lillibridge subsidiary, we also provide management, leasing, marketing, facility development and advisory services to highly rated hospitals and health systems throughout the United States.

        We were incorporated in Kentucky in 1983, commenced operations in 1985 and reorganized as a Delaware corporation in 1987. We operate through three reportable business segments: triple-net leased properties, senior living operations and MOB operations. For additional information, see our Consolidated Financial Statements and the related notes, including "Note 2—Accounting Policies," included in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2010 (the "2010 Form 10-K").

        Our business strategy is comprised of three principal objectives: (1) generating consistent, reliable and growing cash flows; (2) maintaining a well-diversified portfolio; and (3) preserving our investment grade balance sheet and liquidity.

        Our principal executive offices are located at 111 South Wacker Drive, Suite 4800, Chicago, Illinois, 60606, and our telephone number is (877) 483-6827. We maintain a website on the Internet at http://www.ventasreit.com. Information on our website is not incorporated by reference herein and our web address is included in this prospectus as an inactive textual reference only.

Recent Developments

        On May 12, 2011, we acquired substantially all of Atria's real estate assets (the "Atria Acquisition") from private equity funds managed by Lazard Real Estate Partners LLC and its affiliates. The aggregate consideration for the transaction was approximately $3.2 billion, comprised of 24,958,543 shares of our common stock (having a value of approximately $1.38 billion based on the closing price of our common stock on May 12, 2011), approximately $168 million in cash and the assumption or repayment of approximately $1.6 billion of net debt, subject to a post-closing net debt adjustment. As a result of the Atria Acquisition, we added to our senior living operating portfolio 118 private pay seniors housing communities located primarily in affluent coastal markets such as the New York metropolitan area, New England and California. Immediately prior to the closing of the Atria Acquisition, Atria spun off its management operations to a newly formed entity that continues to operate the acquired assets under long-term management agreements with us.

        In February 2011, we signed a definitive agreement to acquire NHP in a stock-for-stock transaction valued at $7.4 billion. Pursuant to the terms and subject to the conditions set forth in the agreement, at the effective time of the merger, each outstanding share of NHP common stock will be converted into the right to receive 0.7866 shares of our common stock. Upon completion of the transaction, our portfolio will consist of over 1,300 properties in 47 U.S. states, the District of Columbia and two Canadian provinces. We expect to complete the NHP transaction in the third quarter of 2011, although we cannot assure you that the transaction will close on such timetable or at all.


RISK FACTORS

        Before you invest in shares of our common stock, you should carefully consider the risks involved. These risks include, but are not limited to:

Risks Relating to Our Common Stock

        Although our common stock is listed on the New York Stock Exchange, such listing does not provide any assurance that an active public market for the common stock will be sustained. We cannot predict what effect, if any, that future market sales of our common stock or the availability of our common stock for sale will have on the prevailing market price of the common stock. In addition, the stock market in recent years has experienced price and volume fluctuations that often have been unrelated or disproportionate to the operating performance of companies. These fluctuations, as well as general economic and market conditions, may adversely affect the market price of our common stock.

        As of May 13, 2011, we had 188,080,247 shares of our common stock outstanding. Except for 3,697,541 shares held by the selling stockholders that are subject to a lockup agreement that limits the selling stockholders' ability to transfer such shares until November 12, 2012, and shares held by our affiliates, all of our outstanding shares of common stock are available for immediate sale. Sales of substantial amounts of our common stock, or the perception that such sales could occur, could adversely affect prevailing market prices of the common stock.

        We may issue equity in the future in connection with acquisitions or strategic transactions, including our pending acquisition of NHP, to adjust our ratio of debt to equity, including through repayment of outstanding debt, to fund expansion of our operations or for other purposes. We may issue shares of our common stock at prices or for consideration that is greater or less than the price at which the shares of common stock are being offered by this prospectus. To the extent we issue additional equity securities, your percentage ownership of our common stock would be reduced.

PLAN OF DISTRIBUTION

        The shares of our common stock offered by this prospectus are subject to restrictions under the Registration Rights Agreement and the Lockup Agreement. Subject to those restrictions, sales of shares of our common stock by the selling stockholders named in this prospectus, which for this purpose includes certain transferees, may be made from time to time in one or more transactions, on the New York Stock Exchange, in the over-the-counter market or any other exchange or quotation system on which shares of our common stock may be listed or quoted, in negotiated transactions or in a combination of any such methods of sale, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The shares may be offered directly, to or through agents designated from time to time or to or through brokers or dealers, or through any combination of these methods of sale. The methods by which the shares may be sold include:

        An agent, broker or dealer may receive compensation in the form of discounts, concessions or commissions from the selling stockholders or the purchasers of the shares for whom such brokers or dealers may act as agents or to whom they sell as principals, or both (which compensation as to a particular broker or dealer might be in excess of customary commissions). A member firm of an exchange on which our common stock is traded may be engaged to act as a selling stockholder's agent in the sale of shares by the selling stockholders.

        Subject to the following paragraph, in connection with distributions of the shares of our common stock offered by this prospectus or otherwise, the selling stockholders may enter into hedging transactions with brokers or dealers or other financial institutions with respect to our common stock. In connection with these transactions, the brokers or dealers or other financial institutions may engage in short sales of our common stock in the course of hedging the positions they assume with the selling stockholders. Such hedging transactions may require or permit the selling stockholders to deliver the shares to such brokers or dealers or other financial institutions to settle the hedging transactions. The selling stockholders may also sell our common stock short and deliver the shares to close out those short positions. If so required by applicable law, this prospectus, as amended or supplemented, may be used to effect:

        The selling stockholders agreed under the Lockup Agreement, until November 12, 2012, not to enter into any swap or any other agreement, transaction or series of transactions that hedges or transfers, in whole or in part, directly or indirectly, any of the economic consequences of their ownership of any of the Merger Consideration Shares. The same restrictions would apply to certain

Table of Contents

transferees of the selling stockholders, but not transferees who purchase shares offered by this prospectus.

        In addition, any shares of our common stock covered by this prospectus that qualify for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus.

        Subject to the Lockup Agreement, the selling stockholders may transfer, pledge or loan the shares to a transferee, pledgee, donee or successor that, in turn, may sell the shares. In those circumstances, the transferee, pledgee, donee or successor would become a selling stockholder under this prospectus and, if required under the Securities Act, will be identified in a prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus is a part prior to making an offer or sale under this prospectus. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions that require the delivery of shares of our common stock, which the broker-dealer or other financial institution may then resell pursuant to this prospectus.

        Each broker-dealer that receives our common stock for its own account pursuant to this prospectus must acknowledge that it will deliver the prospectus in connection with any sale of our common stock. If required, this prospectus may be amended or supplemented on a continual basis to describe a specific plan of distribution.

        The selling stockholders and any other person participating in such distribution will be subject to certain provisions of the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the timing of purchases and sales of any of our common stock by the selling stockholders and any other such person. In addition, Regulation M of the Exchange Act may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to the common stock. In addition, the anti-manipulation rules under the Exchange Act may apply to sales of the securities in the market. All of the foregoing may affect the marketability of the securities and the ability of any person to engage in market-making activities with respect to the securities.

        The selling stockholders and any brokers, dealers, agents or others that participate with the selling stockholders in the distribution of the shares offered by this prospectus may be deemed to be "underwriters" within the meaning of the Securities Act, and any underwriting discounts, commissions or fees received by such persons and any profit on the resale of the shares purchased by such persons may be deemed to be underwriting commissions or discounts under the Securities Act.

        We have agreed to indemnify the selling stockholders named herein against certain liabilities that they may incur in connection with the sale of the shares registered hereunder, including liabilities arising under the Securities Act, and to contribute to payments that the selling stockholders may be required to make with respect thereto. Agents, brokers and dealers may be entitled under agreements entered into by the selling stockholders or us to indemnification against certain civil liabilities, including liabilities under the Securities Act.

        There can be no assurance that the selling stockholders will sell any or all of the shares offered hereby.

        We will bear all fees and expenses of registration of the shares offered by this prospectus, other than any underwriting fees, discounts, commissions and related expenses attributable to the sale of shares offered hereby (including the fees and expenses of any underwriters and such underwriters' counsel). The fees and expenses of registration to be borne by us referred to in the foregoing sentence shall include, without limitation, printing expenses, reasonable fees and expenses of one counsel to the selling stockholders and fees and expenses of all other persons retained by us in connection with the consummation of the transactions hereby. We estimate that the total expenses of this offering payable by us will be $335,000.
