**PROSPECTUS SUMMARY** 

*This summary highlights selected information that is presented in greater detail elsewhere, or incorporated by reference, in this prospectus. It does not contain all of the information that may be important to you and your investment decision. Before investing in our securities, you should carefully read this entire prospectus, including the matters set forth in the section titled "Risk Factors" and the financial statements and related notes and other information that we incorporate by reference herein, including our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q.

**Overview** 

We are a leading provider of cloud communications, video meetings, collaboration, and contact center software-as-a-service solutions. We believe that our innovative, cloud-based communication and contact center solutions disrupt the large market for business communications and collaboration by providing flexible and cost-effective solutions that support mobile and distributed workforces. We enable convenient and effective communications for organizations across all their locations and employees, enabling them to be more productive and more responsive.

Our cloud-based business communications and collaboration solutions are designed to be easy to use, providing a user identity across multiple locations and devices, including smartphones, tablets, PCs and desk phones. Our solutions can be deployed rapidly and configured and managed easily. Our cloud-based solutions are location and device independent and better suited to address the needs of modern mobile and global enterprise workforces than are legacy on-premise systems. Through our open Application Programming Interface (API) platform, we enable third-party developers and customers to integrate our solution with leading business applications to customize their own business workflows.

We have a portfolio of cloud-based offerings that are subscription based, made available at different rates varying by the specific functionalities, services, and number of users. We primarily generate revenues from the sale of subscriptions to our offerings. Our subscription plans have monthly, annual, or multi-year contractual terms. We believe that this flexibility in contract duration is important to meet the different needs of our customers. For the year ended December 31, 2022, subscriptions revenues accounted for 90% or more of our total revenues. The remainder of our revenues has historically been primarily comprised of product revenues from the sale of pre-configured phones and professional services. We do not develop or manufacture physical phones and offer it as a convenience for a total solution to our customers in connection with subscriptions to our services. We rely on third-party providers to develop and manufacture these devices and fulfillment partners to successfully serve our customers.

We have based these forward-looking statements largely on our current expectations and projections about our business, the industry in which we operate and financial trends that we believe may affect our business, financial condition, results of operations and prospects, and these forward-looking statements are not guarantees of future performance or development. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein until after we distribute this prospectus, whether as a result of any new information, future events or otherwise.

In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section titled "Risk Factors" of any Annual Report on Form 10-K and any Quarterly Report on Form 10-Q incorporated by reference in this prospectus and in the section of any related prospectus supplement titled "Risk Factors."

**USE OF PROCEEDS** 

All of the shares of Class A Common Stock being offered hereby are being sold by the selling stockholder identified in this prospectus or permitted transferees. We will not receive any of the proceeds from the sale of shares of Class A Common Stock by the selling stockholder or permitted transferees. We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of the shares to be sold by the selling stockholder, including registration, listing fees, printers and accounting fees and fees and disbursements of counsel (collectively, the Registration Expenses). Other than Registration Expenses, the selling stockholder will bear any selling discounts, commissions, placement agent fees, fees or expenses of outside counsel of the selling stockholder or other similar expenses payable with respect to sales of shares.

**DETERMINATION OF OFFERING PRICE** 

We cannot currently determine the price or prices at which shares of our Class A Common Stock may be sold by the selling stockholder under this prospectus.

**MARKET INFORMATION FOR CLASS A COMMON STOCK AND DIVIDEND POLICY** 

**Market Information** 

Our Class A Common Stock has been traded on the NYSE under the symbol "RNG" since September 27, 2013. On March 2, 2023, the last reported sale price for our Class A Common Stock was $33.84 per share.

**Holders of Record** 

As of December 31, 2022, there were 34 stockholders of record. The number of record holders does not include beneficial holders who hold their shares in "street name," meaning that the shares are held for their accounts by a broker or other nominee. Accordingly, we believe that the total number of beneficial holders is higher than the number of our stockholders of record.

**Dividend Policy** 

We have never declared or paid, any cash dividends on our Class A Common Stock. We currently intend to retain all of our future earnings, if any, to finance our operations and do not anticipate paying any cash dividends on our Class A Common Stock in the foreseeable future. Any future determination as to the declaration and payment of dividends will be at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects, and other factors our board of directors may deem relevant.

Copies of these documents have been filed with the SEC as exhibits to our Annual Reports on Form 10-K.

Our second amended and restated certificate of incorporation provides for two classes of common stock: Class A and Class B Common Stock. In addition, our second amended and restated certificate of incorporation authorizes shares of undesignated preferred stock, the rights, preferences, and privileges of which may be designated from time to time by our board of directors.

Our authorized capital stock consists of 1,350,000,000 shares, all with a par value of $0.0001 per share, of which:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 1,000,000,000 shares are Class A Common Stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 250,000,000 shares are Class B Common Stock; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 100,000,000 are preferred stock, of which 200,000 are designated as Series A Convertible Preferred Stock.

**Class A and Class B Common Stock** 

Our second amended and restated certificate of incorporation provides for two classes of common stock: Class A and Class B Common Stock.

***Voting Rights***

Holders of our Class A and Class B Common Stock have identical rights, provided however that, except as otherwise expressly provided in our second amended and restated certificate of incorporation or required by applicable law, on any matter that is submitted to a vote of our stockholders, holders of Class A Common Stock are entitled to one vote per share of Class A Common Stock and holders of Class B Common Stock are entitled to 10 votes per share of Class B Common Stock. Holders of shares of Class A and Class B Common Stock vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders, and shares of Series A Convertible Preferred Stock are also entitled to vote as a single class with the holders of the Class A and Class B Common Stock, with voting power relating to the conversion rights of such series of preferred stock, except that the Series A Convertible Preferred Stock is entitled to a separate class vote over certain specified matters and, additionally, there would be a separate vote of our Class A and Class B Common Stock as separate classes in the following circumstances:

if we propose to amend our second amended and restated certificate of incorporation (i) to increase or decrease the par value of the shares of the Class A or Class B Common Stock or (ii) to alter or change the powers, preferences or special rights of the shares of a class of our common stock so as to affect them adversely;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if we propose to treat the shares of a class of our common stock differently with respect to any dividend or
distribution of cash, property or shares of our stock paid or distributed by us;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if we propose to treat the shares of a class of our common stock differently with respect to any subdivision or
combination of the shares of a class of our common stock; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if we propose to treat the shares of a class of our common stock differently in connection with a change of
control with respect to any consideration into which the shares are converted or any consideration paid or otherwise distributed to our stockholders.

Under our second amended and restated certificate of incorporation, we may not increase or decrease the authorized number of shares of Class A or Class B Common Stock without the affirmative vote of the holders of a majority of the combined voting power of the outstanding shares of Class A and Class B Common Stock, voting together as a single class.

Under our second amended and restated certificate of incorporation, we may not issue any shares of Class B Common Stock, other than upon exercise of options, warrants, or similar rights to acquire Class B Common Stock outstanding immediately prior to the completion of our initial public offering or in connection with stock dividends and similar transactions, unless that issuance is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class B Common Stock.

We have not provided for cumulative voting for the election of directors in our second amended and restated certificate of incorporation.

***Economic Rights***

Except as otherwise expressly provided in our second amended and restated certificate of incorporation or required by applicable law, shares of Class A and Class B Common Stock have the same rights and privileges and rank equally, share ratably and are identical in all respects as to all matters, including, without limitation those described below.

***Dividends and Distributions***

Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of Class A and Class B Common Stock are entitled to share equally, identically and ratably, on a per share basis, with respect to any dividend or distribution of cash, property or shares of our capital stock paid or distributed by us, unless different treatment of the shares of each such class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A and Class B Common Stock, each voting separately as a class. In the event a dividend or distribution is paid in the form of shares of Class A or Class B Common Stock or rights to acquire shares of such stock, the holders of Class A Common Stock shall receive Class A Common Stock, or rights to acquire Class A Common Stock, as the case may be, and the holders of Class B Common Stock shall receive Class B Common Stock, or rights to acquire Class B Common Stock, as the case may be.

***Liquidation Rights***

Upon our liquidation, dissolution or winding-up, the holders of Class A and Class B Common Stock are entitled to share equally, identically and ratably in all assets remaining after the payment of any liabilities and the liquidation preferences and any accrued or declared but unpaid dividends, if any, with respect to any outstanding preferred stock, unless different treatment of the shares of each class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A and Class B Common Stock, each voting separately as a class.

***Change of Control Transactions***

Upon (A) the closing of the sale, transfer or other disposition of all or substantially all of our assets, (B) the consummation of a merger, reorganization, consolidation or share transfer which results in our voting securities

------

##### [**Table of Contents**](#toc)
outstanding immediately prior to the transaction (or the voting securities issued with respect to our voting securities outstanding immediately prior to the transaction) representing less than a majority of the combined voting power of our voting securities or the voting securities of the surviving or acquiring entity or (C) the closing of the transfer (whether by merger, consolidation or otherwise), in one transaction or a series of related transactions, to a person or group of affiliated persons of securities of the company if, after closing, the transferee person or group would hold 50% or more of our outstanding voting stock (or the outstanding voting stock of the surviving or acquiring entity), the holders of Class A and Class B Common Stock will be treated equally and identically with respect to shares of Class A or Class B Common Stock owned by them, unless different treatment of the shares of each class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A and Class B Common Stock, each voting separately as a class.

***Subdivisions and Combinations***

If we subdivide or combine in any manner outstanding shares of Class A or Class B Common Stock, the outstanding shares of the other class will be subdivided or combined in the same manner, unless different treatment of the shares of each class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A and Class B Common Stock, each voting as a separate class.

***Conversion***

Each share of Class B Common Stock is convertible at any time at the option of the holder into one share of Class A Common Stock. In addition, each share of Class B Common Stock will convert automatically into one share of Class A Common Stock upon (i) the date specified by affirmative vote or written consent of the holders of at least 67% of the outstanding shares of Class B Common Stock or (ii) any transfer, whether or not for value, except for certain transfers described in our second amended and restated certificate of incorporation, including, without limitation, transfers for tax and estate planning purposes, so long as the transferring holder of Class B Common Stock continues to hold exclusive voting and dispositive power with respect to the shares transferred.

Upon the death of a holder of Class B Common Stock who is a natural person, the Class B Common Stock held by that person or his or her permitted estate planning entities will convert automatically into Class A Common Stock; provided, however, that Vladimir Shmunis and Vlad Vendrow, our two founders, may transfer voting control of shares of Class B Common Stock to another Class B stockholder contingent or effective upon his death or permanent incapacity without triggering a conversion to Class A Common Stock, provided that the shares of Class B Common Stock so transferred shall convert to Class A Common Stock nine months after the death of the transferring stockholder.

In addition, with respect to each holder of Class B Common Stock, all of such holder's shares of Class B Common Stock will automatically convert into shares of Class A Common Stock on the seven-year anniversary of the closing date of our initial public offering; provided that any such holder's Class B Common Stock will not automatically convert into Class A Common Stock, notwithstanding the seven-year automatic conversion provision, and such holder will continue to be deemed to hold Class B Common Stock, as long as such holder, together with his or her permitted estate planning entities, continues to beneficially own a number of shares of Class B Common Stock equal to at least 50% of the number of shares of Class B Common Stock that such holder beneficially owned immediately prior to completion of our initial public offering.

Once transferred and converted into Class A Common Stock, such Class B Common Stock shall be retired and may not be reissued.

All outstanding shares of Class B Common Stock will convert into Class A Common Stock on the date on which the number of outstanding shares of Class B Common Stock represents less than 10% of the aggregate combined number of outstanding shares of Class A and Class B Common Stock. After such conversion, no further shares of Class B Common Stock will be issued.

**Preferred Stock** 

Our board of directors may, without further action by our stockholders, fix, by resolution or resolutions and set forth in one or more certificates of designation filed pursuant to the Delaware General Corporation Law the powers, designations, preferences and relative, participation, optional or other rights, if any, and the qualifications, limitations or restrictions thereof, if any, of any wholly unissued preferred stock, including, without limitation, authority to fix by resolution or resolutions that dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and liquidation preferences of any such series, and the number of shares constituting any such series and the designation thereof, or any of the foregoing, the terms of which may provide for terms that may be superior to the rights of our Class A or Class B Common Stock.

An aggregate of 100,000,000 shares of preferred stock are authorized in our second amended and restated certificate of incorporation, 200,000 of which have been designated as Series A Convertible Preferred Stock. The issuance of our preferred stock could adversely affect the voting power of holders of our Class A or Class B Common Stock and the likelihood that such holders will receive dividend payments and payments upon liquidation, and the terms of the Series A Convertible Preferred Stock provide for certain preferences over our Class A and Class B Common Stock with respect to, among other things, the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of our affairs, and participating rights on the payment of dividends. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change of control or other corporate action.

**Provisions of Our Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and Delaware Anti-Takeover Law** 

Our second amended and restated certificate of incorporation provides for a board of directors with each director serving a one-year term. Because our stockholders do not have cumulative voting rights, our stockholders holding a majority of the voting power of the shares of capital stock outstanding will be able to elect all of our directors. Our second amended and restated certificate of incorporation and amended and restated bylaws provide that, once our outstanding shares of Class B Common Stock represent less than a majority of the combined voting power of our common stock, all stockholder actions must be effected at a duly called meeting of stockholders and not by a consent in writing, and that only the majority of our whole board of directors, chair of the board of directors or our chief executive officer may call a special meeting of stockholders.

***Stockholder Action***

Our second amended and restated certificate of incorporation provides that our stockholders are able to take action by written consent. When the outstanding shares of our Class B Common Stock represent less than a majority of the combined voting power of our common stock, our stockholders will no longer be able to take action by written consent, and will only be able to take action at annual or special meetings of our stockholders, except as otherwise expressly provided by the terms of any series of preferred stock permitting the holders of such series of preferred stock to act by written consent.

As described above in "-Class A and Class B Common Stock-Voting Rights," our second amended and restated certificate of incorporation further provides for a dual class common stock structure, which provides our founders, early investors, executives and employees with significant influence over all matters requiring stockholder approval, including the election of directors and significant corporate transactions, such as a merger or other sale of our company or its assets.

Our second amended and restated certificate of incorporation and amended and restated bylaws require a supermajority stockholder vote for the rescission, alteration, amendment or repeal of the second amended and restated certificate of incorporation or amended and restated bylaws by stockholders. Our second amended and

------

##### [**Table of Contents**](#toc)
restated certificate of incorporation and amended and restated bylaws also provide that vacancies occurring on our board of directors for any reason and newly created directorships resulting from an increase in the authorized number of directors may be filled only by vote of a majority of the remaining members of our board of directors. Our amended and restated bylaws establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors. The combination of the lack of cumulative voting, supermajority stockholder voting requirements for certain amendments to our second amended and restated certificate of incorporation, the ability of the board to fill vacancies and the advance notice provisions will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock will make it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.

These provisions, including the dual class structure of our common stock, may have the effect of deterring hostile takeovers or delaying changes in our control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts.

***Section 203 of the Delaware General Corporation Law***

We are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• before such date, the board of directors of the corporation approved either the business combination or the
transaction that resulted in the stockholder becoming an interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the
interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on or after such date, the business combination is approved by the board of directors and authorized at an annual
or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines business combination to include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any merger or consolidation involving the corporation and the interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the
interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any
stock of the corporation to the interested stockholder;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any transaction involving the corporation that has the effect of increasing the proportionate share of the stock
or any class or series of the corporation beneficially owned by the interested stockholder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other
financial benefits by or through the corporation.

In general, Section 203 defines an "interested stockholder" as an entity or person who, together with the person's affiliates and associates, beneficially owns, or is an affiliate or associate of the corporation and within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. The transfer agent's address is 250 Royall Street, Canton, Massachusetts 02021, and its phone number is (877) 373-6374.

**MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS OF OUR CLASS A COMMON STOCK** 

The following is a summary of the material U.S. federal income tax consequences to non-U.S. holders (as defined below) of the ownership and disposition of our Class A Common Stock sold by the selling stockholder or its permitted transferees pursuant to this prospectus but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, U.S. Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought and will not seek any ruling from the Internal Revenue Service, or the IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.

This summary applies only to Class A Common Stock sold by the selling stockholder or its permitted transferees pursuant to this prospectus. It does not address the tax consequences arising under the laws of any non-U.S., state or local jurisdiction or under U.S. federal gift and estate tax laws, the potential application of the alternative minimum tax, the Medicare tax on net investment income or any other tax considerations applicable to an investor's particular circumstances or to investors that may be subject to special tax rules, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• banks, insurance companies or other financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax-exempt organizations or governmental organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• real estate investment trusts, regulated investment companies or grantor trusts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• U.S. expatriates and former citizens or long-term residents of the United States;

##### [**Table of Contents**](#toc)
In addition, if a partnership (or entity or arrangement classified as such for U.S. federal income tax purposes) holds our Class A Common Stock, the tax treatment of a partner generally will depend on the status of the partner and upon the activities of the partnership. Accordingly, partnerships that hold our Class A Common Stock, and partners in such partnerships, should consult their tax advisors regarding the tax consequences of the purchase, ownership and disposition of our Class A Common Stock.

***This discussion is for informational purposes only and is not tax advice. You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our Class A Common Stock arising under the U.S. federal estate or gift tax laws or under the laws of any state, local, non-U.S. or other taxing jurisdiction or under any applicable tax treaty.***

**Non-U.S. Holder Defined** 

For purposes of this discussion, you are a non-U.S. holder if you are a beneficial owner of shares of our Class A Common Stock that, for U.S. federal income tax purposes, is not a partnership or:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or
organized in the United States or under the laws of the United States or any political subdivision thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an estate whose income is subject to U.S. federal income tax regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a trust (x) whose administration is subject to the primary supervision of a U.S. court and which has one or
more U.S. persons who have the authority to control all substantial decisions of the trust or (y) which has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes.

**Distributions** 

We have not made any distributions on our Class A Common Stock, and we do not plan to make any distributions on our Class A Common Stock. However, if we do make distributions on our Class A Common Stock, those payments will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce your basis in our Class A Common Stock, but not below zero, and then will be treated as gain from the sale of stock. Under applicable Treasury Regulations, we may withhold up to 30% of the gross amount of the entire distribution even if the amount constituting a dividend, as described above, is less than the gross amount. You may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Subject to the discussions below on effectively connected income, backup withholding and FATCA, any dividend paid to you generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty between the United States and your country of residence. In order to receive a reduced treaty rate, you must provide us with an IRS Form W-8BEN, IRS Form W-8BEN-E or other appropriate version of IRS Form W-8 (or the applicable successor form), including a U.S. taxpayer identification number, if required, certifying qualification for the reduced rate. In addition, you will be required to update such forms and certifications from time to time as required by law. If you are eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty, you may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. If you hold our Class A Common Stock through a financial institution or other agent acting on your behalf, you will be required to provide appropriate documentation to the agent, which may then be required to provide certification to the relevant paying agent, either directly or through other intermediaries.

Dividends received by you that are effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable tax treaty, that are attributable to a permanent establishment or a fixed base maintained by you in the United States), are generally exempt from such withholding tax, subject to the discussions below on backup withholding and FATCA. In order to obtain this exemption, you must provide us with an IRS Form W-8ECI properly certifying such exemption. Such effectively connected dividends, although not subject to withholding tax, generally are taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits. In addition, if you are a non-U.S. holder treated as a corporation for U.S. federal income tax purposes, dividends you receive that are effectively connected with your conduct of a trade or business in the United States may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty. You should consult your tax advisor regarding any applicable tax treaties that may provide for different rules.

**Gain on Disposition of Our Class A Common Stock** 

Subject to discussions below regarding backup withholding, you generally will not be required to pay U.S. federal income tax on any gain realized upon the sale or other disposition of our Class A Common Stock unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the gain is effectively connected with your conduct of a trade or business in the United States (and, if required
by an applicable income tax treaty, the gain is attributable to a permanent establishment or a fixed base maintained by you in the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• you are an individual who is present in the United States for a period or periods aggregating 183 days or more
during the calendar year in which the sale or disposition occurs and certain other conditions are met; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our Class A Common Stock constitutes a U.S. real property interest by reason of our status as a "United
States real property holding corporation," or USRPHC, for U.S. federal income tax purposes at any time within the shorter of the five year period preceding your disposition of, or your holding period for, our Class A Common Stock.

In general, a corporation is a USRPHC if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide property interests and its other assets used or held for use in a trade or business (all as determined for U.S. federal income tax purposes). We believe that we are not currently and will not become a USRPHC, and the remainder of this discussion so assumes. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our worldwide real property and other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our Class A Common Stock is "regularly traded on an established securities market" (within the meaning of Section 897(c)(3) of the Code), such Class A Common Stock will be treated as U.S. real property interests only if you actually or constructively hold more than 5% of such regularly traded Class A Common Stock at any time during the shorter of the five year period preceding your disposition of, or your holding period for, our Class A Common Stock.

If you are a non-U.S. holder described in the first bullet above, you will be required to pay U.S. federal income tax on the net gain derived from the sale under regular graduated U.S. federal income tax rates, and a corporate non-U.S. holder described in the first bullet above also may be subject to the branch profits tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty. If you are an individual non-U.S. holder described in the second bullet above, you will be required to pay a flat 30% U.S. federal income tax (or such lower rate specified by an applicable income tax treaty) on the gain derived from the sale, which gain may be offset by U.S.-source capital losses for the year. You should consult your tax advisor regarding any applicable income tax or other treaties that may provide for different rules.

##### [**Table of Contents**](#toc)
**Backup Withholding and Information Reporting** 

Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address, and the amount of tax withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of residence.

Payments of dividends on or of proceeds from the disposition of our Class A Common Stock made to you may be subject to additional information reporting and backup withholding at a current rate of 24% unless you establish an exemption, for example, by properly certifying your non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or another appropriate version of IRS Form W-8 (or an applicable successor form). Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person.

Backup withholding is not an additional tax; rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

**Foreign Account Tax Compliance Act (FATCA)** 

Sections 1471 through 1474 of the Code, and the Treasury regulations and administrative guidance issued thereunder, commonly referred to as "FATCA", generally impose a U.S. federal withholding tax of 30% on dividends on and the gross proceeds from a disposition of our Class A Common Stock paid to a "foreign financial institution" (as defined in the Code) unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise establishes an exemption. FATCA also generally imposes a U.S. federal withholding tax of 30% on dividends on and the gross proceeds from a disposition of our Class A Common Stock paid to a "non-financial foreign entity" (as specifically defined in the Code) unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding direct and indirect U.S. owners of the entity or otherwise establishes an exemption.

The withholding provisions described above generally apply to payments of dividends on our Class A Common Stock. The Treasury Secretary has issued proposed regulations providing that the withholding provisions under FATCA do not apply with respect to the gross proceeds from a sale or other disposition of Class A Common Stock, which may be relied upon by taxpayers until final regulations are issued. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this section. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. You should consult your tax advisors regarding the potential application of FATCA to your investment in, and ownership and disposition of, our Class A Common Stock.

***Each prospective investor should consult its tax advisor regarding the particular U.S. federal, state and local and non-U.S. tax consequences of purchasing, holding and disposing of our Class A Common Stock, including the consequences of any proposed change in applicable laws.***

**Item 14.** **Indemnification of Directors and Officers.** <br>

Section 145 of the Delaware General Corporation Law authorizes a corporation's board of directors to grant, and authorizes a court to award, indemnity to officers, directors and other corporate agents.

As permitted by Section 102(b)(7) of the Delaware General Corporation Law, the Registrant's second amended and restated certificate of incorporation includes provisions that may eliminate the personal liability of its directors and officers for monetary damages for breach of their fiduciary duty as directors and officers.

In addition, as permitted by Section 145 of the Delaware General Corporation Law, the second amended and restated certificate of incorporation and the amended and restated bylaws of the Registrant provide that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Registrant shall indemnify its directors and officers for serving the Registrant in those capacities or for
serving other business enterprises at the Registrant's request, to the fullest extent permitted by Delaware law. Delaware law provides that a corporation may indemnify such person if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the Registrant and, with respect to any criminal proceeding, had no reasonable cause to believe such person's conduct was unlawful.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Registrant may, in its discretion, indemnify employees and agents in those circumstances where
indemnification is permitted by applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Registrant is required to advance expenses, as incurred, to its directors and officers in connection with
defending a proceeding, except that such director or officer shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification under the amended and restated bylaws of the Registrant or the
Delaware General Corporation Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Registrant will not be obligated pursuant to the amended and restated bylaws to indemnify a person with
respect to proceedings initiated by that person, except with respect to proceedings authorized by the Registrant's board of directors or brought to enforce a right to indemnification or otherwise required under the amended and restated bylaws
of the Registrant or applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The rights conferred in the second amended and restated certificate of incorporation and amended and restated
bylaws are not exclusive, and the Registrant is authorized to enter into indemnification

------

##### [**Table of Contents**](#toc)
agreements with its directors, officers, employees and agents and to obtain insurance to indemnify such persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Registrant may not retroactively amend the bylaw provisions to reduce its indemnification obligations to
directors, officers, employees and agents.

The Registrant's policy is to enter into separate indemnification agreements with each of its directors and officers that provide the maximum indemnity allowed to directors and executive officers by Section 145 of the Delaware General Corporation Law and also to provide for certain additional procedural protections. The Registrant also maintains directors and officers insurance to insure such persons against certain liabilities.

These indemnification provisions and the indemnification agreements entered into between the Registrant and its officers and directors may be sufficiently broad to permit indemnification of the Registrant's officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act.

**Item 15.** **Recent Sales of Unregistered Securities.** <br>

None.

**Item 16.** **Exhibits and Financial Statements Schedules.** <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Exhibits

The exhibits to the registration statement are listed in the Exhibit Index to this registration statement and are incorporated herein by reference.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Financial statement schedules

All schedules have been omitted because either they are not required, are not applicable or the information is otherwise set forth in the financial statements and related notes thereto incorporated by reference herein.

**Item 17.** **Undertakings** <br>

The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

This opinion is furnished to you in connection with the Registration Statement on Form S-1 (the "Registration Statement"), to be filed on or about March 3, 2023 by RingCentral, Inc. (the "Company") with the Securities and Exchange Commission in connection with the registration for resale under the Securities Act of 1933, as amended (the "Securities Act"), of up to 1,265,456 shares of the Company's Class A common stock, $0.0001 par value per share (the "Shares").

We are acting as counsel for the Company in connection with the registration for resale under the Securities Act of the Shares. In such capacity, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary for the purposes of rendering this opinion. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity with the originals of all documents submitted to us as copies, the authenticity of the originals of such documents and the legal competence of all signatories to such documents.

We express no opinion herein as to the laws of any state or jurisdiction other than the General Corporation Law of the State of Delaware (including the statutory provisions and all applicable judicial decisions interpreting those laws) and the federal laws of the United States of America.

On the basis of the foregoing, we are of the opinion that the Shares have been duly authorized and are validly issued, fully paid and nonassessable.
