RISK FACTORS

An investment in our shares involves risks. You should carefully consider the risk factors described below, together with all of the other information included in this prospectus supplement and the accompanying prospectus or incorporated by reference into this prospectus supplement and the accompanying prospectus, including the discussion under the “Risk Factors” section in our Annual Report on Form 10-K for the year ended December 31, 2022, as such discussion may be amended or updated in other reports filed by us with the SEC, before making an investment in our shares.

Risks Arising from Our Common Stock

The share price of our common stock could be affected by several factors.

The share price of our common stock depends upon several factors, including, but not limited to: our financial condition, performance and prospects; general economic and financial market conditions; changes in estimates by analysts; the market for similar securities issued by REITs; and our ability to meet analysts’ estimates. In addition, the market price of our common stock may be affected by future sales of our securities, including additional issuances of common stock and securities convertible into common stock. These factors, among others, could significantly depress the trading price of our common stock.

Holders of any future outstanding shares of our preferred stock will have liquidation, dividend and other rights that are senior to the rights of the holders of our common stock.

Our board of directors has the authority to designate and issue preferred stock with liquidation, dividend and other rights that are senior to those of our common stock. If we are in arrears in the payment of dividends on our preferred stock, we may be prohibited or otherwise restricted in paying any dividends in our common stock. In addition, the holders of any shares of our preferred stock that may be issued in the future would receive, upon our voluntary or involuntary liquidation, dissolution or winding up, before any payment is made to holders of our common stock, their liquidation preferences as well as any accrued and unpaid distributions. Dividend, redemption and liquidating payments on our preferred stock would reduce the remaining amount of our assets, if any, available for distribution to holders of our common stock.

Our issuance of additional securities may reduce the market price for our shares.

The market price of our common stock may be affected by future sales of our securities, including those made pursuant to each equity distribution agreement and other additional issuances of common stock and securities convertible into common stock. We may also issue common stock as consideration or partial consideration in connection with our investments and acquisitions or for achieving certain benchmarks related to such investments and acquisitions. The number of shares of common stock that we may issue or that we may issue upon conversion could be significant and dilutive to our existing stockholders.

Our ability to pay dividends in the future is subject to many factors.

Our primary unsecured credit facility restricts our ability to pay cash dividends on our common stock if we default under the credit facility, and other financing agreements or instruments that we enter into or issue (including preferred stock) in the future also may limit our ability to pay cash dividends on our common stock. If we default under our primary unsecured credit facility, or if future financing agreements or instruments restrict our ability to pay cash dividends, we will be restricted in our ability to pay cash dividends on our common stock unless we can refinance amounts outstanding under those agreements or instruments.

S-3

Under Delaware law, cash dividends on capital stock may only be paid from “surplus” or, if there is no “surplus,” from the corporation’s net profits for the then-current or the preceding fiscal year. Unless we operate profitably, our ability to pay cash dividends on our common stock would require the availability of adequate “surplus,” which is defined as the excess, if any, of our net assets (total assets less total liabilities) over our capital. Further, even if adequate surplus is available to pay cash dividends on our common stock, we may not have sufficient cash to pay dividends on our common stock.

Our ability to pay dividends may be impaired if any of the risks described in this prospectus supplement and the accompanying prospectus or incorporated by reference herein and in the accompanying prospectus were to occur. In addition, payment of our dividends depends upon our earnings, our cash flows, our financial condition, maintenance of our REIT status and other factors as our board of directors may deem relevant from time to time.

Certain provisions in our certificate of incorporation and by-laws may restrict your ownership of shares of our capital stock and/or discourage or prevent a change in control.

In order to assist us in maintaining our qualification as a REIT for U.S. federal income tax purposes, our by-laws provide that no person may own, or be deemed to own by virtue of the attribution rules of the Internal Revenue Code of 1986, as amended, more than 9.8% of the value of our outstanding capital stock, subject to certain exceptions. For this purpose, all options, warrants, convertible securities or other rights to acquire our common stock will be treated as if all such rights had been exercised. If any shares or other securities in excess of this limit are issued or transferred to any person, such issuance or transfer shall be valid only with respect to such amount of shares or securities as does not exceed this limit, and such issuance or transfer will be void with respect to the excess. These and other provisions in our certificate of incorporation, by-laws and Delaware law could delay, prevent or deter a transaction or change in control, including an acquisition of us by a third party, that might involve a premium price for our common stock or otherwise be favorable to you as a stockholder.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein contain statements that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. When we use words such as “may,” “will,” “intend,” “should,” “believe,” “expect,” “anticipate,” “project,” “pro forma,” “estimate” or similar expressions that do not relate solely to historical matters, we are making forward-looking statements. In particular, these forward-looking statements include, but are not limited to, those relating to our opportunities to acquire, develop or sell properties; our ability to close our anticipated acquisitions, investments or dispositions on currently anticipated terms, or within currently anticipated timeframes; the expected performance of our operators/tenants and properties; our expected occupancy rates; our ability to declare and to make distributions to stockholders; our investment and financing opportunities and plans; our continued qualification as a REIT; and our ability to access capital markets or other sources of funds.

Forward-looking statements are not guarantees of future performance and involve risks and uncertainties that may cause our actual results to differ materially from our expectations discussed in the forward-looking statements. This may be a result of various factors, including, but not limited to:

S-5

We assume no obligation to update or revise publicly any forward-looking statements, whether because of new information, future events or otherwise, except as required by law, or to update the reasons why actual results could differ from those projected in any forward-looking statements.

USE OF PROCEEDS

The net proceeds from this offering will be approximately $1.495 billion ($1.720 billion if the underwriters exercise their option to purchase additional shares of common stock in full), after deducting estimated offering expenses payable by us. We intend to use the net proceeds from the offering for the acquisition of properties within the seniors housing and skilled nursing sectors, including those currently under contract and for general corporate purposes. On October 30, 2023, we disclosed approximately $1.0 billion of fully funded investments under contract and have entered into agreements to purchase an incremental $2.0 billion of properties as of November 6, 2023. In total, the $3.0 billion of granular acquisition activity is comprised of approximately $2.4 billion and $600 million of investments in the seniors housing and skilled nursing sectors, respectively. Pending such use, the net proceeds may be invested in short-term, investment grade, interest-bearing securities, certificates of deposit or indirect or guaranteed obligations of the United States.

UNDERWRITING

BofA Securities, Inc. and Goldman Sachs & Co. LLC are acting as underwriters of the offering. Subject to the terms and conditions set forth in an underwriting agreement among us, Welltower OP LLC and the underwriters, we have agreed to sell to BofA Securities, Inc. and Goldman Sachs & Co., and each such institution has agreed, severally and not jointly, to purchase from us, 10,500,000 and 7,000,000, respectively, shares of our common stock.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitment of the nondefaulting underwriter may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The underwriters are purchasing the shares of common stock from us at $85.50 per share (representing approximately $1.496 billion aggregate proceeds to us, before we deduct our out-of-pocket expenses of approximately $1 million, or approximately $1.721 billion if the underwriters’ option to purchase additional shares described below is exercised in full). The underwriters may offer the shares of common stock 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. In connection with the sale of the shares of common stock offered hereby, the underwriters may be deemed to have received compensation in the form of underwriting discounts. The underwriters may effect such transactions by selling shares of common stock to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and / or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal.

Option to Purchase Additional Shares

We have granted an option to the underwriters, exercisable for 30 days after the date of this prospectus supplement, subject to the conditions contained in the underwriting agreement, to purchase up to 2,625,000 additional shares at the price per share set forth on the cover page of this prospectus supplement. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional shares proportionate to that underwriter’s initial amount reflected in the allocation described above.

No Sales of Similar Securities

We, our executive officers and directors have agreed not to directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of the common stock, or any other securities convertible into or exercisable or exchangeable for shares of the common stock, directly or indirectly, or any securities convertible into or exchangeable or exercisable for shares of our common

S-8

stock or other securities of Welltower Inc., or file any registration statement under the Securities Act with respect to any of the foregoing or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of shares of the common stock, whether any such transaction described in sell or transfer any common stock or securities convertible into, exchangeable for, exercisable for, or repayable with common stock, for 30 days after the date of this prospectus supplement without

first obtaining the written consent of BofA Securities, Inc. and Goldman Sachs & Co. LLC. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

The foregoing shall not apply to (i) the shares of the common stock issuable upon exchange of the 2.750% exchangeable senior notes due 2028 of Welltower OP LLC (“Welltower OP”), (ii) the issuance by Welltower of shares of the common stock upon the redemption of units of Welltower OP pursuant to the limited liability company agreement of Welltower OP, (iii) the issuance by Welltower of shares of the common stock, options to purchase shares of the common stock, restricted stock or restricted stock units, or the issuance by Welltower of shares of the common stock upon the exercise of options to purchase shares of the common stock or the vesting of restricted stock or restricted stock units, in each case pursuant to any incentive or compensation plan or arrangement described in this prospectus supplement or the documents incorporated herein by reference, or the filing of a registration statement on Form S-8 with respect there to, or (iv) the issuance by Welltower of shares of the common stock or securities convertible into, exchangeable for or that represent the right to receive shares of the common stock in connection with (x) the acquisition by Welltower or any of its subsidiaries of the securities, business, property or other assets of another person or entity or pursuant to an employee benefit plan assumed by Welltower in connection with any such acquisition, and the issuance of any such securities pursuant to any such agreement, or (y) any joint ventures, commercial relationships or other strategic transactions of Welltower or any of its subsidiaries; provided that the aggregate number of shares of the common stock that Welltower may sell or issue or agree to sell or issue pursuant to clause (iv) shall not exceed 10% of the total number of shares of the common stock outstanding immediately following the date of the under underwriting agreement; and provided, further, that in the case of clause (iv), each recipient of any such securities issued pursuant thereto shall agree to transfer restrictions substantially to the effect agreed to by our directors and executive officers as described above.

New York Stock Exchange Listing

The shares are listed on the New York Stock Exchange under the symbol “WELL.”

Short Positions

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short

sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to

purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’

S-9

option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.

Neither we nor the underwriters 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. In addition, neither we nor the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Distribution

In connection with the offering, the underwriters may distribute prospectuses by electronic means, such as e-mail.

Other Relationships

The underwriters and/or their respective affiliates currently provide, have provided and in the future may provide investment banking, commercial banking, corporate trust and/or advisory services to us from time to time for which they currently receive, have received and in the future may receive customary fees and expenses and may have entered into and in the future may enter into other transactions with us.

In addition, in the ordinary course of their business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

THE COMPANY

We are an S&P 500 company headquartered in Toledo, Ohio and are driving the transformation of health care infrastructure. We invest with leading seniors housing operators, post-acute providers and health systems to fund the real estate and infrastructure needed to scale innovative care delivery models and improve people’s wellness and overall health care experience. Welltower^TM, a REIT, owns interests in properties concentrated in major, high-growth markets in the United States (“U.S.”), Canada and the United Kingdom, consisting of seniors housing, post-acute communities and outpatient medical properties.

Our principal executive offices are located at 4500 Dorr Street, Toledo, Ohio, 43615, and our telephone number is (419) 247-2800. Our internet address is at www.welltower.com.

As previously disclosed, on March 7, 2022, the company formerly known as Welltower Inc., a Delaware corporation (“Old Welltower”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with the company formerly known as WELL Merger Holdco Inc., a Delaware corporation, which was a wholly owned subsidiary of Old Welltower (“New Welltower”), and WELL Merger Holdco Sub Inc., a Delaware corporation, which was a wholly owned subsidiary of New Welltower (“Merger Sub”). The purpose of the transactions contemplated by the Merger Agreement was for Old Welltower to implement a corporate reorganization into a new holding company structure commonly referred to as an Umbrella Partnership Real Estate Investment Trust, or UPREIT.

Effective on April 1, 2022, pursuant to the Merger Agreement, Merger Sub merged with and into Old Welltower, with Old Welltower continuing as the surviving corporation and a wholly owned subsidiary of New Welltower (the “Merger”). The Merger was conducted pursuant to Section 251(g) of the General Corporation Law of the State of Delaware (the “DGCL”), which provides for the formation of a holding company (i.e., New Welltower) without a vote of the shareholders of the constituent corporation (i.e., Old Welltower). In connection with the Merger, Old Welltower’s name was changed to Welltower OP Inc., and New Welltower inherited the name “Welltower Inc.”

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of the debt securities of Welltower Inc. and the debt securities of Welltower OP Inc. In this description, unless specifically noted otherwise or unless the context otherwise requires, all references to “we,” “us,” “our” or the “Company” refer to either Welltower Inc. or Welltower OP Inc., as applicable, as issuer of the debt securities. The debt securities sold under this prospectus will be our direct obligations, which may be secured or unsecured, and which may be senior or subordinated indebtedness. The debt securities may be guaranteed on a secured or unsecured, senior or subordinated basis, by one or more of our subsidiaries. The debt securities will be issued under one or more indentures among us, the specified guarantor, if any, and a specified trustee. Any indenture will be subject to and governed by the Trust Indenture Act of 1939, as amended. The statements made in this prospectus relating to any indentures and the debt securities to be issued under the indentures are summaries of certain provisions or anticipated provisions of the indentures.

The following is a summary of the material terms of our debt securities. Because it is a summary, it does not contain all of the information that may be important to you. If you want more information, you should read the forms of indentures to be entered into among us, the guarantor, if any, and The Bank of New York Mellon Trust Company, N.A., as trustee, for senior debt securities, senior subordinated debt securities and junior subordinated debt securities which we have filed as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find Additional Information.” The summary set forth below does not purport to be complete and is subject to and qualified in its entirety by reference to the descriptions of the particular terms of the securities described in the applicable prospectus supplement and any related free writing prospectus.

General

We may issue debt securities that rank “senior,” “senior subordinated” or “junior subordinated.” The debt securities that we refer to as “senior” will be our direct obligations and will rank equally and ratably in right of payment with our other indebtedness not subordinated. We may issue debt securities that will be subordinated in right of payment to the prior payment in full of senior debt, as defined in the applicable prospectus supplement or any related free writing prospectus, and may rank equally and ratably with the other senior subordinated indebtedness. We refer to these as “senior subordinated” securities. We may also issue debt securities that may be subordinated in right of payment to the senior subordinated securities. These would be “junior subordinated” securities. We have filed with the registration statement, of which this prospectus is a part, separate forms of indentures for senior debt securities, senior subordinated debt securities and junior subordinated debt securities. We refer to each of these three indentures as an “indenture.” We refer to senior subordinated and junior subordinated securities as “subordinated.”

We may issue the debt securities without limit as to aggregate principal amount, in one or more series, in each case as we establish in one or more supplemental indentures. We need not issue all debt securities of one series at the same time. Unless we otherwise provide, we may reopen a series, without the consent of the holders of the series, for issuances of additional securities of that series.

Unless otherwise provided in the prospectus supplement relating to any debt securities, the debt securities will not constitute obligations of our subsidiaries. Creditors and preferred equity holders of our subsidiaries are entitled to a preferred claim on the assets of those subsidiaries. Consequently, in the event of a liquidation or reorganization of any subsidiary, creditors and preferred equity holders of the subsidiary are likely to be paid in full before any distribution is made to the Company and holders of debt securities, except to the extent that the Company is itself recognized as a creditor of such subsidiary, in which case the Company’s claims would still be subordinate to any security interests in the assets of such subsidiary and any debt of such subsidiary senior to that held by the Company.

The senior debt indenture provides and we anticipate that any other indenture will provide that we may, but need not, designate more than one trustee under an indenture, each with respect to one or more series of debt

7

securities. Any trustee under any indenture may resign or be removed with respect to one or more series of debt securities, and we may appoint a successor trustee to act with respect to that series. The applicable prospectus supplement and any related free writing prospectus will describe the specific terms relating to the series of debt securities we will offer, including, where applicable, the following:

8

We may issue debt securities at less than the principal amount payable at maturity. We refer to these securities as “original issue discount” securities. If material or applicable, we will describe in the applicable prospectus supplement special U.S. federal income tax, accounting and other considerations applicable to original issue discount securities.

Except as may be described in any prospectus supplement, an indenture will not contain any provisions that would limit our ability to incur indebtedness or that would afford holders of the debt securities protection in the event of a highly leveraged or similar transaction involving us or in the event of a change of control. You should review carefully the applicable prospectus supplement for information with respect to events of default and covenants applicable to the securities being offered.

Denominations, Interest, Registration and Transfer

Unless otherwise described in the applicable prospectus supplement, we will issue the debt securities of any series that are registered securities in denominations that are even multiples of $1,000, other than global securities, which may be of any denomination.

Unless otherwise specified in the applicable prospectus supplement, we will pay the interest, principal and any premium at the corporate trust office of the trustee, such other address as the trustee may designate from time to time by notice to the holders and the Company or the principal corporate trust office of any successor trustee. At our option, however, we may make payment of interest by check mailed to the address of the person entitled to the payment as it appears in the applicable register or by wire transfer of funds to that person at an account maintained within the United States.

If we do not punctually pay or otherwise provide for interest on any interest payment date, the defaulted interest will be paid either:

You may have your debt securities divided into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. We call this an “exchange.” You may exchange or transfer debt securities at the office of the applicable trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may change this appointment to another entity or perform it ourselves.

The entity performing the role of maintaining the list of registered holders is called the “registrar.” It will also perform transfers. You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The registrar will make the transfer or exchange only if it is satisfied with your proof of ownership.

Guarantees

Debt securities issued by Welltower Inc. may be fully and unconditionally guaranteed by Welltower OP Inc., and debt securities issued by Welltower OP Inc. may be fully and unconditionally guaranteed by Welltower Inc. The applicable prospectus supplement relating to a series of debt securities will provide that those debt securities will have the benefit of a guarantee by Welltower Inc. or Welltower OP Inc, as applicable. The guarantees will be general obligations of each guarantor. If a series of debt securities is so guaranteed, a supplemental indenture to the applicable base indenture will be executed by each guarantor.

The obligations of each guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent transfer or conveyance under applicable law. A guarantor will be permitted to

9

consolidate or merge with, or sell substantially all of its assets to another company, other than us or another guarantor, only if (i) the other company is an entity organized under the laws of one of the states of the United States or the District of Columbia or under United States federal law and agrees to be legally responsible for the guarantee; and (ii) immediately after the merger, sale of assets or other transaction, there would exist no event of default on the debt securities or any event that would be an event of default on the debt securities if the requirements regarding notice of default or continuing default for a specific period of time were disregarded. The terms of any guarantee and the conditions upon which a guarantor may be released from its obligations under that guarantee will be set forth in the applicable prospectus supplement.

Merger, Consolidation or Sale of Assets

Under an indenture, we are or generally will be permitted to consolidate or merge with another company. In addition, we are or will be permitted to sell substantially all of our assets to another company, or to buy substantially all of the assets of another company. However, we may not take any of these actions unless the following conditions are met:

Certain Covenants

Existence. Except as permitted and described above under “—Merger, Consolidation or Sale of Assets,” we will agree to do all things necessary to preserve and keep our existence, rights and franchises, provided that it is in our best interests for the conduct of business.

Provisions of Financial Information. To the extent permitted by law, we will agree to file all annual, quarterly and other reports and financial statements with the SEC and the trustee on or before the applicable SEC filing dates whether or not we remain required to do so under the Exchange Act.

Additional Covenants. Any additional or different covenants or modifications to the foregoing covenants with respect to any series of debt securities will be described in the applicable prospectus supplement.

Events of Default and Related Matters

Events of Default. The term “event of default” for any series of debt securities means any of the following:

10

Remedies If an Event of Default Occurs. If an event of default has occurred and has not been cured, the trustee or the holders of at least a majority in principal amount of the debt securities of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. If an event of default occurs because of certain events in bankruptcy, insolvency or reorganization, the principal amount of all the debt securities of that series will be automatically accelerated, without any action by the trustee or any holder. At any time after the trustee or the holders have accelerated any series of debt securities, but before a judgment or decree for payment of the money due has been obtained, the holders of at least a majority in principal amount of the debt securities of the affected series may, under certain circumstances, rescind and annul such acceleration.

The trustee will be required to give notice to the holders of debt securities within 90 days after a default under the applicable indenture; provided, however, that in case of any default that may be cured, no such notice will be required to be given until at least 30 days after the occurrence thereof. The trustee may withhold notice to the holders of any series of debt securities of any default with respect to that series, except a default in the payment of the principal of or interest on any debt security of that series, if specified responsible officers of the trustee in good faith determine that withholding the notice is in the interest of the holders.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the applicable indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. We refer to this as an “indemnity.” If reasonable indemnity satisfactory to it is provided, the holders of a majority in principal amount of the outstanding securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture, subject to certain limitations.

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

However, you are entitled at any time to bring a lawsuit for the payment of money due on your security after its due date.

Every year we will furnish to the trustee a written statement by certain of our officers certifying that to their knowledge we are in compliance with the applicable indenture, or else specifying any default.

11

Modification of an Indenture

There are three types of changes we can make to the indentures and the debt securities:

Changes Requiring Your Approval. First, there are changes we cannot make to your debt securities without your specific approval. The following is a list of those types of changes:

Changes Requiring a Majority Vote. The second type of change is the kind that requires the vote of holders of debt securities owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not materially adversely affect holders of the debt securities. We require the same vote to obtain a waiver of a past default; however, we cannot obtain a waiver of a payment default or any other aspect of an indenture or the debt securities listed in the first category described above under “—Changes Requiring Your Approval” unless we obtain your individual consent to the waiver.

Changes Not Requiring Approval. The third type of change does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes that would not materially adversely affect holders of the debt securities.

Further Details Concerning Voting. Debt securities are not considered outstanding, and therefore the holders of debt securities are not eligible to vote on matters relating thereto, if we have deposited or set aside in trust for such holders money for payment or redemption of debt securities or if we own or one of our affiliates owns the debt securities. The holders of debt securities are also not eligible to vote if the debt securities have been fully defeased as described below under “—Discharge, Defeasance and Covenant Defeasance—Full Defeasance.”

Discharge, Defeasance and Covenant Defeasance

Discharge. We may discharge some obligations to holders of any series of debt securities that either have become due and payable or will become due and payable within one year, or scheduled for redemption within one year, by irrevocably depositing with the trustee, in trust, funds in the applicable currency in an amount sufficient to pay the debt securities, including any premium and interest.

Full Defeasance. We can, under particular circumstances, effect a full defeasance of your series of debt securities. By this we mean we can legally release ourselves from any payment or other obligations on the debt

12

securities if, among other things, we put in place the arrangements described below to repay you and deliver certain certificates and opinions to the trustee:

If we did accomplish full defeasance, you would have to rely solely on the trust deposit for repayment on the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent. You would also be released from any subordination provisions.

Covenant Defeasance. We can make the same type of deposit described above and be released from some of the restrictive covenants in the debt securities. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and securities set aside in trust to repay the securities and you would be released from any subordination provisions.

If we did accomplish covenant defeasance, the following provisions of an indenture and the debt securities would no longer apply:

If we did accomplish covenant defeasance, you could still look to us for repayment of the debt securities if a shortfall in the trust deposit occurred. If one of the remaining events of default occurred, for example, our bankruptcy, and the debt securities became immediately due and payable, there may be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Subordination

We will describe in the applicable prospectus supplement the terms and conditions, if any, upon which any series of senior subordinated securities or junior subordinated securities is subordinated to debt securities of another series or to our other indebtedness. The terms will include a description of:

13

Global Securities

If so set forth in the applicable prospectus supplement, we may issue the debt securities of a series in whole or in part in the form of one or more global securities that will be deposited with a depositary identified in the prospectus supplement or its nominee. If so represented, interests in such global note will be shown on, and transfers thereof will be effected only through, records maintained by the designated depositary and its participants. We may issue global securities in either registered or bearer form and in either temporary or permanent form. The specific terms of the depositary arrangement with respect to any series of debt securities will be described in the prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

The following is a summary of certain terms of our common stock and preferred stock that Welltower Inc. may issue. Because this summary is not complete, you should refer to our certificate of incorporation and Welltower Inc.’s by-laws (our “by-laws”), which documents provide additional information regarding our common stock and preferred stock, and the applicable provisions of the DGCL. See also “Description of Certain Provisions of Our Certificate of Incorporation and By-Laws” below. Copies of our certificate of incorporation and by-laws, as amended, are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. The summary set forth below is subject to and qualified in its entirety by reference to the description of the particular terms of the securities described in the applicable prospectus supplement or any related free writing prospectus. In this description, all references to “we,” “us,” “our” or the “Company” refer only to Welltower Inc. and not to any of its subsidiaries. In description, all references to “common stock” refer to common stock, par value $1.00 per share, of Welltower Inc., and all references to “preferred stock” refer to preferred stock, par value $1.00 per share, of Welltower Inc.

Common Stock

Common stockholders are entitled to receive dividends if, when and as declared by our board of directors and after payment of, or provision for, full cumulative dividends on and any required redemptions of shares of preferred stock then outstanding. Common stockholders have one vote per share, and there are no cumulative voting rights. If we are voluntarily or involuntarily liquidated or dissolved, common stockholders are to share ratably in our distributable assets remaining after the satisfaction of all of our debts and liabilities and the preferred stockholders’ prior preferential rights. Common stockholders do not have preemptive rights. The common stock will be, when issued, fully paid and nonassessable. The common stock is subject to restrictions on transfer under certain circumstances described under “Restrictions on Transfer of Securities” below. The transfer agent for our common stock is Computershare Trust Company, N.A.

The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock which are outstanding or which we may designate and issue in the future. See “Preferred Stock” below.

Preferred Stock

Our board of directors or a duly authorized committee thereof will determine the designations, preferences, limitations and relative rights of our authorized and unissued preferred stock. These may include:

14

The issuance of shares of preferred stock, or the issuance of rights to purchase shares of preferred stock, could discourage an unsolicited acquisition proposal. In addition, the rights of holders of shares of our common stock will be subject to, and may be adversely affected by, the rights of holders of any shares of preferred stock that we may issue in the future.

The following describes some general terms and provisions of the preferred stock to which a prospectus supplement or a related free writing prospectus may relate. The statements below describing the preferred stock do not purport to be complete and are in all respects subject to and qualified in their entirety by reference to the applicable provisions of our certificate of incorporation, including any applicable certificate of designation, and our by-laws.

The prospectus supplement or any related free writing prospectus will describe the specific terms as to each issuance of shares of preferred stock, including:

15

As described under “Description of Depositary Shares,” we may, at our option, elect to offer depositary shares evidenced by depositary receipts. If we elect to do this, each depositary receipt will represent a fractional interest in a share of the particular series of preferred stock issued and deposited with a depositary. The applicable prospectus supplement will describe the terms of the depositary receipts.

The shares of preferred stock are subject to restrictions on transfer under certain circumstances described under “Restrictions on Transfer of Securities” below.

Rank

Unless our board of directors otherwise determines and we so specify in the applicable prospectus supplement, we expect that the shares of preferred stock will, with respect to distribution rights and rights upon liquidation or dissolution, rank senior to all of our shares of common stock.

Distributions

Holders of shares of preferred stock of each series will be entitled to receive cash and/or share distributions at the rates and on the dates shown in the applicable prospectus supplement. Even though the shares of preferred stock may specify a fixed rate of distribution, our board of directors must authorize and declare those distributions and they may be paid only out of assets legally available for payment. We will pay each distribution to holders of record as they appear on our share transfer books on the record dates fixed by our board of directors. In the case of shares of preferred stock represented by depositary receipts, the records of the depositary identified in the applicable prospectus supplement, or any successor depositary, will determine the persons to whom dividends are payable.

Distributions on any series of preferred stock may be cumulative or noncumulative, as provided in the applicable prospectus supplement. We refer to each particular series, for ease of reference, as the applicable series. Cumulative distributions will be cumulative from and after the date shown in the applicable prospectus supplement. If our board of directors fails to authorize a distribution on any applicable series that is noncumulative, the holders will have no right to receive, and we will have no obligation to pay, a distribution in respect of the applicable distribution period, whether or not distributions on that series are declared payable in the future. If the applicable series is entitled to a cumulative distribution, we may not declare, or pay or set aside for payment, any full distributions on any other series of preferred stock ranking, as to distributions, on a parity with or junior to the applicable series, unless we declare, and either pay or set aside for payment, full cumulative distributions on the applicable series for all past distribution periods and the then-current distribution period. If the applicable series does not have a cumulative distribution, we must declare, and pay or set aside for payment, full distributions for the then-current distribution period only. When distributions are not paid, or set aside for payment, in full upon any applicable series and the shares of any other series ranking on a parity as to distributions with the applicable series, we must declare, and pay or set aside for payment, all distributions upon the applicable series and any other parity series proportionately, in accordance with accrued and unpaid distributions of the several series. For these purposes, accrued and unpaid distributions do not include unpaid distribution periods on noncumulative preferred stock. No interest will be payable in respect of any distribution payment that may be in arrears.

Except as provided in the immediately preceding paragraph, unless we declare, and pay or set aside for payment, full cumulative distributions, including for the then-current period, on any cumulative applicable series,

16

we may not declare, or pay or set aside for payment, any distributions upon shares of common stock or any other equity securities ranking junior to or on a parity with the applicable series as to distributions or upon liquidation. The foregoing restriction does not apply to distributions paid in shares of common stock or other equity securities ranking junior to the applicable series as to distributions and upon liquidation. If the applicable series is noncumulative, we need only declare, and pay or set aside for payment, the distribution for the then-current period, before declaring distributions on shares of common stock or junior or parity securities. In addition, under the circumstances that we could not declare a distribution, we may not redeem, purchase or otherwise acquire for any consideration any shares of common stock or other parity or junior equity securities, except upon conversion into or exchange for shares of common stock or other junior equity securities. We may, however, make purchases and redemptions otherwise prohibited pursuant to certain redemptions or pro rata offers to purchase the outstanding shares of the applicable series and any other parity series of preferred stock.

We will credit any distribution payment made on an applicable series first against the earliest accrued but unpaid distribution due with respect to the series.

Redemption

We may have the right or may be required to redeem one or more series of preferred stock, as a whole or in part, in each case upon the terms, if any, and at the times and at the redemption prices shown in the applicable prospectus supplement.

If a series of preferred stock is subject to mandatory redemption, we will specify in the applicable prospectus supplement the number of shares we are required to redeem, when those redemptions start, the redemption price, and any other terms and conditions affecting the redemption. The redemption price will include all accrued and unpaid distributions, except in the case of noncumulative preferred stock. The redemption price may be payable in cash or other property, as specified in the applicable prospectus supplement. If the redemption price for shares of preferred stock of any series is payable only from the net proceeds of our issuance of shares of capital stock, the terms of the preferred stock may provide that, if no shares of such capital stock shall have been issued or to the extent the net proceeds from any issuance are insufficient to pay in full the aggregate redemption price then due, the shares of preferred stock will automatically and mandatorily be converted into shares of the applicable capital stock pursuant to conversion provisions specified in the applicable prospectus supplement.

Liquidation Preference

The applicable prospectus supplement will show the liquidation preference of the applicable series. Upon our voluntary or involuntary liquidation, before any distribution may be made to the holders of our shares of common stock or any other shares of capital stock ranking junior in the distribution of assets upon any liquidation to the applicable series, the holders of that series will be entitled to receive, out of our assets legally available for distribution to stockholders, liquidating distributions in the amount of the liquidation preference, plus an amount equal to all distributions accrued and unpaid. In the case of a noncumulative applicable series, accrued and unpaid distributions include only the then-current distribution period. Unless otherwise provided in the applicable prospectus supplement, after payment of the full amount of the liquidating distributions to which they are entitled, the holders of shares of preferred stock will have no right or claim to any of our remaining assets. If liquidating distributions shall have been made in full to all holders of shares of preferred stock, our remaining assets will be distributed among the holders of any other shares of capital stock ranking junior to the shares of preferred stock upon liquidation, according to their rights and preferences and in each case according to their number of shares.

If, upon any voluntary or involuntary liquidation, our available assets are insufficient to pay the amount of the liquidating distributions on all outstanding shares of that series and the corresponding amounts payable on all shares of capital stock ranking on a parity in the distribution of assets with that series, then the holders of that

17

series and all other equally ranking shares of capital stock shall share ratably in the distribution in proportion to the full liquidating distributions to which they would otherwise be entitled. For these purposes, our consolidation or merger with or into any other corporation or other entity, or the sale, lease or conveyance of all or substantially all of our property or business, shall not be deemed to constitute a liquidation.

Voting Rights

Holders of the shares of preferred stock will not have any voting rights, except as described below or as otherwise from time to time required by law or as specified in the applicable prospectus supplement. As more fully described under “Description of Depositary Shares” below, if we elect to issue depositary shares, each representing a fraction of a share of a series of preferred stock, each holder thereof will in effect be entitled to a fraction of a vote per depositary share.

Unless otherwise provided for in an applicable series, so long as any shares of preferred stock are outstanding, we may not, without the affirmative vote or consent of the holders of a majority of the shares (or such greater vote or consent as is required by the then-current rules of any stock exchange or trading market on which we shall have listed the applicable series of preferred stock for trading or as otherwise provided in our organizational documents) of each series of preferred stock outstanding at that time:

The authorization, creation or increase of the authorized or issued amount of any class or series of shares of capital stock ranking on parity with or junior to a series of preferred stock with respect to distribution and liquidation rights will not be deemed to materially and adversely affect that series.

Conversion Rights

We will describe in the applicable prospectus supplement the terms and conditions, if any, upon which you may, or we may require you to, convert shares of any series of preferred stock into shares of common stock or any other class or series of shares of capital stock. The terms will include the number of shares of common stock or other capital stock into which the shares of preferred stock are convertible, the conversion price or manner of determining it, the conversion period, provisions as to whether conversion will be at the option of the holders of the series or at our option, the events requiring an adjustment of the conversion price, and provisions affecting conversion upon the redemption of shares of the series.

Our Exchange Rights

We will describe in the applicable prospectus supplement the terms and conditions, if any, upon which we can require you to exchange shares of any series of preferred stock for debt securities. If an exchange is required, you will receive debt securities with a principal amount equal to the liquidation preference of the applicable series of preferred stock. The other terms and provisions of the debt securities will not be materially less favorable to you than those of the series of preferred stock being exchanged.

18

DESCRIPTION OF DEPOSITARY SHARES

This section describes the general terms and provisions of shares of preferred stock represented by depositary shares. The applicable prospectus supplement and any related free writing prospectus will describe the specific terms of the depositary shares offered through that prospectus supplement and any general terms outlined in this section that will not apply to those depositary shares.

We have summarized in this section certain terms and provisions of the deposit agreement, the depositary shares and the receipts representing depositary shares. The summary is not complete. You should read the forms of deposit agreement and depositary receipt that we will file with the SEC at or before the time of the offering of the depositary shares for additional information before you buy any depositary shares. In this description, all references to “we,” “us,” “our” or the “Company” refer only to Welltower Inc. and not to any of its subsidiaries.

General

We may, at our option, elect to offer fractional interests in shares of preferred stock, rather than shares of preferred stock. If we exercise this option, we will appoint a depositary to issue depositary receipts representing those fractional interests. Shares of preferred stock of each series represented by depositary shares will be deposited under a separate deposit agreement between us and the depositary. The prospectus supplement relating to a series of depositary shares will provide the name and address of the depositary. Subject to the terms of the applicable deposit agreement, each owner of depositary shares will be entitled to all of the dividend, voting, conversion, redemption, liquidation and other rights and preferences of the shares of preferred stock represented by those depositary shares.

Depositary receipts issued pursuant to the applicable deposit agreement will evidence ownership of depositary shares. Upon surrender of depositary receipts at the office of the depositary, and upon payment of the charges provided in and subject to the terms of the deposit agreement, a holder of depositary shares will be entitled to receive the shares of preferred stock underlying the surrendered depositary receipts.

Distributions

A depositary will be required to distribute all dividends or other cash distributions received in respect of the applicable shares of preferred stock to the record holders of depositary receipts evidencing the related depositary shares in proportion to the number of depositary receipts owned by the holders. Fractions will be rounded down to the nearest whole cent.

If the distribution is other than in cash, a depositary will be required to distribute property received by it to the record holders of depositary receipts entitled thereto, unless the depositary determines that it is not feasible to make the distribution. In that case, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders of depositary shares.

Depositary shares that represent shares of preferred stock converted or exchanged will not be entitled to distributions. The deposit agreement also will contain provisions relating to the manner in which any subscription or similar rights we offer to holders of shares of preferred stock will be made available to holders of depositary shares. All distributions will be subject to obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary.

Withdrawal of Shares of Preferred Stock

You may receive the number of whole shares of your series of preferred stock and any money or other property represented by your depositary receipts after surrendering your depositary receipts at the corporate trust office of the depositary. Partial shares of preferred stock will not be issued. If the depositary shares that you

19

surrender exceed the number of depositary shares that represent the number of whole shares of preferred stock you wish to withdraw, then the depositary will deliver to you at the same time a new depositary receipt evidencing the excess number of depositary shares. Once you have withdrawn your shares of preferred stock, you will not be entitled to redeposit those shares of preferred stock under the deposit agreement in order to receive depositary shares. We do not expect that there will be any public trading market for withdrawn shares of preferred stock.

Redemption of Depositary Shares

If we redeem a series of the preferred stock underlying the depositary shares, the depositary will redeem those shares from the proceeds it receives. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to the series of the preferred stock. The redemption date for depositary shares will be the same as that of the preferred stock. If we are redeeming less than all of the depositary shares, the depositary will select the depositary shares we are redeeming by lot or pro rata as the depositary may determine.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed outstanding. All rights of the holders of the depositary shares and the related depositary receipts will cease at that time, except the right to receive the money or other property to which the holders of depositary shares were entitled upon redemption. Receipt of the money or other property is subject to surrender to the depositary of the depositary receipts evidencing the redeemed depositary shares.

Voting of the Underlying Shares of Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, a depositary will be required to mail the information contained in the notice of meeting to the record holders of the depositary shares representing such preferred stock. Each record holder of depositary receipts on the record date will be entitled to instruct the depositary as to how the holder’s depositary shares will be voted. The record date for the depositary shares will be the same as the record date for the preferred stock. The depositary will vote the shares as you instruct. We will agree to take all reasonable action that the depositary deems necessary in order to enable it to vote the preferred stock in that manner. If you do not instruct the depositary how to vote your shares, the depositary will abstain from voting those shares. The depositary will not be responsible for any failure to carry out any voting instruction, or for the manner or effect of any vote, as long as its action or inaction is in good faith and does not result from its negligence or willful misconduct.

Liquidation Preference

Upon our liquidation, whether voluntary or involuntary, each holder of depositary shares will be entitled to the fraction of the liquidation preference accorded each share of preferred stock represented by the depositary shares, as described in the applicable prospectus supplement.

Conversion or Exchange of Shares of Preferred Stock

The depositary shares will not themselves be convertible into or exchangeable for shares of common stock or preferred stock or any of our other securities or property. Nevertheless, if so specified in the applicable prospectus supplement, the depositary receipts may be surrendered by holders to the applicable depositary with written instructions to it to instruct us to cause the conversion of the preferred stock represented by the depositary shares. Similarly, if so specified in the applicable prospectus supplement, we may require you to surrender all of your depositary receipts to the applicable depositary upon our requiring the conversion or exchange of the preferred stock represented by the depositary shares into our debt securities. We will agree that, upon receipt of the instruction and any amounts payable in connection with the conversion or exchange, we will cause the conversion or exchange using the same procedures as those provided for delivery of shares of preferred stock to effect the conversion or exchange. If you are converting only a part of the depositary shares, the depositary will issue you a new depositary receipt for any unconverted depositary shares.

20

Amendment and Termination of a Deposit Agreement

We and the applicable depositary are permitted to amend the provisions of the depositary receipts and the deposit agreement. However, the holders of at least a majority of the applicable depositary shares then outstanding (or such greater approval as is required by the then-current rules of any stock exchange or trading market on which we shall have listed the applicable underlying series of preferred stock for trading or as otherwise provided in our organizational documents) must approve any amendment that adds or increases fees or charges or prejudices an important right of holders. Every holder of an outstanding depositary receipt at the time any amendment becomes effective, by continuing to hold the receipt, will be bound by the applicable deposit agreement, as amended.

Any deposit agreement may be terminated by us upon not less than 30-days’ prior written notice to the applicable depositary if (1) the termination is necessary to preserve our status as a REIT or (2) a majority of each series of preferred stock affected by the termination consents to the termination. When either event occurs, the depositary will be required to deliver or make available to each holder of depositary receipts, upon surrender of the depositary receipts held by the holder, the number of whole or fractional shares of preferred stock as are represented by the depositary shares evidenced by the depositary receipts, together with any other property held by the depositary with respect to the depositary receipts. In addition, a deposit agreement will automatically terminate if:

Charges of a Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of a deposit agreement. In addition, we will pay the fees and expenses of a depositary in connection with the initial deposit of the preferred stock and any redemption of preferred stock. However, holders of depositary receipts will pay any transfer or other governmental charges and the fees and expenses of a depositary for any duties the holders request to be performed that are outside of those expressly provided for in the applicable deposit agreement.

Resignation and Removal of a Depositary

A depositary may resign at any time by providing us notice of its election to resign. In addition, we may at any time remove a depositary. Any resignation or removal will take effect when we appoint a successor depositary and it accepts the appointment. We must appoint a successor depositary within 60 days after delivery of the notice of resignation or removal. A depositary must be a bank or trust company that has its principal office in the United States and a combined capital and surplus of at least $50 million.

Miscellaneous

A depositary will be required to forward to holders of depositary receipts any reports and communications from us that it receives with respect to the related shares of preferred stock, including, without limitation, proxy solicitation materials. Holders of depository receipts will be able to inspect the transfer books of the depository and the list of holders of receipts upon reasonable notice. Neither we nor any depositary will be liable if either party is prevented from or delayed in performing its obligations under a deposit agreement by law or any circumstances beyond its control. Our obligations and those of the depositary under a deposit agreement will be limited to performing duties in good faith and without gross negligence or willful misconduct.

21

Neither we nor any depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or related shares of preferred stock unless satisfactory indemnity is furnished. We and each depositary will be permitted to rely on written advice of counsel or accountants, on information provided by persons presenting shares of preferred stock for deposit, by holders of depositary receipts, or by other persons believed in good faith to be competent to give the information, and on documents believed in good faith to be genuine and signed by a proper party.

If a depositary receives conflicting claims, requests or instructions from any holder of depositary receipts, on the one hand, and us, on the other hand, the depositary shall be entitled to act on the claims, requests or instructions received from us.

DESCRIPTION OF WARRANTS

This section describes the general terms and provisions of the warrants. The applicable prospectus supplement and any related free writing prospectus will describe the specific terms of the warrants offered through that prospectus supplement and any general terms outlined in this section that will not apply to those warrants.

We have summarized in this section certain terms and provisions of the warrant agreement and the warrants. The summary is not complete. You should read the forms of warrant and warrant agreement that we will file with the SEC at or before the time of the offering of the applicable series of warrants for additional information before you buy any warrants. In this description, all references to “we,” “us,” “our” or the “Company” refer only to Welltower Inc. and not to any of its subsidiaries.

We may issue, together with any other securities being offered or separately, warrants entitling the holder to purchase from or sell to us, or to receive from us the cash value of the right to purchase or sell, debt securities, preferred stock, depositary shares or common stock. We and a warrant agent will enter into a warrant agreement pursuant to which the warrants will be issued. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

In the case of each series of warrants, the applicable prospectus supplement and any related free writing prospectus will describe the terms of the warrants being offered thereby. These include the following, if applicable:

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities underlying the warrants and will not be entitled to payments made to holders of those securities.

22

The warrant agreements may be amended or supplemented without the consent of the holders of the warrants to which the amendment or supplement applies to effect changes that are not inconsistent with the provisions of the warrants and that do not adversely affect the interests of the holders of the warrants. However, any amendment that materially and adversely alters the rights of the holders of warrants will not be effective unless the holders of at least a majority of the applicable warrants then outstanding (or such greater approval as is required by the then-current rules of any stock exchange or trading market on which we shall have listed the applicable underlying shares of capital stock for trading or as otherwise provided in our organizational documents) approve the amendment. Every holder of an outstanding warrant at the time any amendment becomes effective, by continuing to hold the warrant, will be bound by the applicable warrant agreement, as amended. The prospectus supplement applicable to a particular series of warrants may provide that certain provisions of the warrants, including the securities for which they may be exercisable, the exercise price, and the expiration date, may not be altered without the consent of the holder of each warrant.

DESCRIPTION OF UNITS

We may, from time to time, issue units comprised of one or more of the other securities that may be offered under this prospectus, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date. In this description, all references to “we,” “us,” “our” or the “Company” refer only to Welltower Inc. and not to any of its subsidiaries.

Any applicable prospectus supplement and any related free writing prospectus will describe:

RESTRICTIONS ON TRANSFER OF SECURITIES

For Welltower Inc. to qualify as a REIT, not more than 50% in value of its outstanding capital stock may be owned, directly or indirectly, by five or fewer individuals at any time during the last half of our taxable year. In order to ensure that this requirement is satisfied, our by-laws (with respect to its common stock and preferred stock) and our certificates of designation (for our preferred stock) provide that no person may acquire securities that would result in the direct or indirect beneficial ownership of more than 9.8% of its common stock or more than 9.8% in value of our outstanding capital stock by such person. For purposes of application of such limitations to any person, all options, warrants, convertible securities or other rights to acquire Welltower Inc.’s capital stock held directly or indirectly by such person will be treated as if all such rights had been exercised. If any securities in excess of this limit are issued or transferred to any person, such issuance or transfer shall be valid only with respect to such amount of securities as does not exceed this limit, and such issuance or transfer will be void with respect to the excess. The board of directors of Welltower Inc. may grant limited exemptions from the ownership restrictions set forth in the by-laws to specified persons if the board determines that each such limited exemption is in the best interests of Welltower Inc. and its stockholders.

Our by-laws and certificates of designation further provide that, if the foregoing stock ownership limitations are determined to be invalid by virtue of any legal decision, statute, rule or regulation, then the transferee of the

23

shares or other securities will be deemed to have acted as our agent in acquiring the shares or other securities that are in excess of the limit, and will be deemed to hold such excess shares or securities on our behalf. As the equivalent of treasury securities for such purposes, the excess securities will not be entitled to any voting rights, will not be considered to be outstanding for quorum or voting purposes, and will not be entitled to receive dividends, interest or any other distribution with respect to such securities. Any person who receives dividends, interest or any other distribution in respect of the excess securities will hold the same as our agent and for the transferee of the excess securities following a permitted transfer.

In addition, under our by-laws and certificates of designation, we may refuse to transfer any shares, passing either by voluntary transfer, by operation of law, or under the last will and testament of any stockholder, if such transfer would or might, in the opinion of our board of directors or counsel, disqualify Welltower Inc. as a REIT.

DESCRIPTION OF CERTAIN PROVISIONS OF CERTIFICATE

OF INCORPORATION AND BY-LAWS OF WELLTOWER INC.

Anti-Takeover Provisions

Our certificate of incorporation and by-laws contain provisions that may have the effect of discouraging persons from acquiring large blocks of our stock or delaying or preventing a change in our control. The material provisions that may have such an effect are:

Limitations on Transactions Involving Us and Our Stockholders

Under our by-laws, in addition to any vote otherwise required by law, our certificate of incorporation or our by-laws, the following transactions will require the affirmative vote of the holders of at least 75% of the voting power of our then-outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class:

24

These provisions will not apply to any of the transactions described above if:

The foregoing summary of certain provisions of our certificate of incorporation and by-laws does not purport to be complete or to give effect to provisions of statutory or common law. The foregoing summary is subject to and qualified in its entirety by reference to the provisions of applicable law and our certificate of incorporation and by-laws, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

SELLING SECURITY HOLDERS

Information about selling security holders and the terms of the securities offered for resale, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment, or in filings we make with the SEC that are incorporated into this prospectus by reference. Selling security holders may be deemed to be underwriters in connection with the securities they resell and any profits on the resale may be deemed to be underwriting discounts and commissions under the Securities Act. The selling security holders will receive all the proceeds from the resale of our securities. We will not receive any proceeds from resales by selling security holders.

25

PLAN OF DISTRIBUTION

Sales by Us

We may sell the securities:

The applicable prospectus supplement and any related free writing prospectus will (1) describe the plan of distribution of the securities, (2) describe the terms of the offering and (3) name any managing underwriter or underwriters, underwriter, dealer or agent involved in the offer and sale of the securities.

We also may, from time to time, authorize underwriters and our agents to offer and sell the securities upon the terms and conditions as are set forth in the applicable prospectus supplement. In connection with the sale of securities, underwriters may be deemed to have received compensation from us in the form of underwriting discounts, commissions or fees and may also receive commissions from purchasers of securities for whom they may act as agent. Underwriters may sell securities to or through dealers, and these dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent, or both. The applicable prospectus supplement will disclose:

Under the Securities Act, underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters and any discounts, commissions and fees received by them and any profit realized by them on resale of the securities may be deemed to be underwriting compensation, discounts and commissions. We may agree to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, and to make contribution to them in connection with those liabilities.

If indicated in the applicable prospectus supplement, we may also offer and sell securities through one or more firms that will remarket the securities. These firms may act as principals for their own account or as our agents. These firms may be deemed to be underwriters in connection with the securities being remarketed. We may agree to indemnify these firms against liabilities, including liabilities under the Securities Act.

Upon the terms and conditions of the applicable prospectus supplement, the underwriters may purchase and sell securities in the open market. These transactions may include short sales, purchases to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in the offering. Stabilizing transactions consist of various bids for or purchases of the securities made by the underwriters in the open market prior to the completion of the offering. The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the other underwriters a portion of the underwriting discount received by it because the representatives of the underwriters have repurchased securities sold by or for the account of that underwriter in stabilizing or short-covering transactions. The underwriters are not required to engage in these activities and may discontinue any of these activities at any time.

If indicated in the applicable prospectus supplement, we may authorize underwriters, agents or dealers to solicit offers by institutions to purchase securities at the offering price set forth in that prospectus supplement

26

under delayed delivery contracts providing for payment and delivery on the dates stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate principal amount of securities sold under contracts will be not less nor more than, the respective amounts stated in the applicable prospectus supplement. Institutions with whom contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions, and other institutions, but will in all cases be subject to our approval. Contracts will not be subject to any conditions except:

In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the proceeds from any offering pursuant to this prospectus and any applicable prospectus supplement.

It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market-making at any time without notice. We cannot give any assurance as to the liquidity of any trading market for any of the securities.

Underwriters and agents will have no responsibility in respect of the delivery or performance of contracts.

Some of the underwriters and their affiliates may engage in transactions with or perform services for us in the ordinary course of business.

Direct sales to investors or our stockholders may be accomplished through subscription offerings or through stockholder purchase rights distributed to stockholders. In connection with subscription offerings or the distribution of stockholder purchase rights to stockholders, if all of the underlying securities are not subscribed for, we may sell any unsubscribed securities to third parties directly or through underwriters or agents. In addition, whether or not all of the underlying securities are subscribed for, we may concurrently offer additional securities to third parties directly or through underwriters or agents. If securities are to be sold through stockholder purchase rights, the stockholder purchase rights will be distributed as a dividend to the stockholders for which they will pay no separate consideration. The prospectus supplement with respect to the offer of securities under stockholder purchase rights will set forth the relevant terms of the stockholder purchase rights, including:

Underwriters and our agents may offer and sell the securities at:

27

Sales by Selling Security Holders

The selling security holders may resell or redistribute the securities from time to time on any stock exchange or automated interdealer quotation system on which the securities are listed, in the over-the-counter market, in privately negotiated transactions, or in any other legal manner, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. Persons who are pledgees, donees, transferees, or other successors in interest of any of the named selling security holders (including, but not limited, to persons who receive securities from a named selling security holder as a gift, partnership distribution or other non-sale-related transfer after the date of this prospectus) may also use this prospectus and are included when we refer to “selling security holders” in this prospectus. The selling security holders may sell the securities by one or more of the following methods, without limitation:

The security holders may also transfer the securities by gift.

The selling security holders may engage brokers and dealers, and any brokers or dealers may arrange for other brokers or dealers to participate in effecting sales of the securities. These brokers, dealers or underwriters may act as principals, or as an agent of a selling security holder. Broker-dealers may agree with a selling security holder to sell a specified number of the securities at a stipulated price per share. If the broker-dealer is unable to sell securities acting as agent for a selling security holder, it may purchase as principal any unsold securities at the stipulated price. Broker-dealers who acquire securities as principals may thereafter resell the securities from time to time in transactions in any stock exchange or automated interdealer quotation system on which the

28

securities are then listed, at prices and on terms then prevailing at the time of sale, at prices related to the then-current market price or in negotiated transactions. Broker-dealers may use block transactions and sales to and through broker-dealers, including transactions of the nature described above.

From time to time, one or more of the selling security holders may pledge, hypothecate or grant a security interest in some or all of the securities owned by them. The pledgees, secured parties or persons to whom the securities have been hypothecated will, upon foreclosure in the event of default, be deemed to be selling security holders. The number of a selling security holder’s securities offered under this prospectus will decrease as and when it takes such actions. The plan of distribution for that selling security holder’s securities will otherwise remain unchanged. In addition, a selling security holder may, from time to time, sell the securities short, and, in those instances, this prospectus may be delivered in connection with the short sales and the securities offered under this prospectus may be used to cover short sales.

The selling security holders and any underwriters, brokers, dealers or agents that participate in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act, and any discounts, concessions, commissions or fees received by them and any profit on the resale of the securities sold by them may be deemed to be underwriting discounts and commissions.

A selling security holder may enter into hedging transactions with broker-dealers and the broker-dealers may engage in short sales of the securities in the course of hedging the positions they assume with that selling security holder, including, without limitation, in connection with distributions of the securities by those broker-dealers. A selling security holder may enter into option or other transactions with broker-dealers that involve the delivery of the securities offered hereby to the broker-dealers, who may then resell or otherwise transfer those securities. A selling security holder may also loan or pledge the securities offered hereby to a broker-dealer and the broker-dealer may sell the securities offered hereby so loaned or upon a default may sell or otherwise transfer the pledged securities offered hereby.

The selling security holders and other persons participating in the sale or distribution of the securities will be subject to applicable provisions of the Exchange Act and the related rules and regulations adopted by the SEC, including Regulation M. This regulation may limit the timing of purchases and sales of any of the securities by the selling security holders and any other person. The anti-manipulation rules under the Exchange Act may apply to sales of securities in the market and to the activities of the selling security holders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities with respect to the particular securities being distributed for a period of up to five-business-days before the distribution. These restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.

We may agree to indemnify the selling security holders and their respective officers, directors, employees and agents, and any underwriter or other person who participates in the offering of the securities, against specified liabilities, including liabilities under the federal securities laws or to contribute to payments the underwriters may be required to make in respect of those liabilities. The selling security holders may agree to indemnify us, the other selling security holders and any underwriter or other person who participates in the offering of the securities, against specified liabilities arising from information provided by the selling security holders for use in this prospectus or any accompanying prospectus supplement, including liabilities under the federal securities laws. In each case, indemnification may include each person who is an affiliate of or controls one of these specified indemnified persons within the meaning of the federal securities laws or is required to contribute to payments the underwriters may be required to make in respect of those liabilities. The selling security holders may agree to indemnify any brokers, dealers or agents who participate in transactions involving sales of the securities against specified liabilities arising under the federal securities laws in connection with the offering and sale of the securities.

We will not receive any proceeds from sales of any securities by the selling security holders.
