FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents that we incorporate by reference herein and therein, contain forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. The words “anticipate,” “believe,” “could,” “expect,” “if,” “intend,” “may,” “predict,” “should,” “will,” “would,” and similar expressions, and the negative thereof, are intended to identify forward-looking statements. These forward-looking statements include, but are not limited to, statements about:

Our forward-looking statements are based on assumptions that we believe to be reasonable but that may not prove to be accurate. We undertake no obligation to publicly update or revise any forward-looking statement, except as required by law.

All of our forward-looking information is subject to risks and uncertainties that could cause actual results to differ materially from the results expected. Although it is not possible to identify all factors, these risks and uncertainties include the risk factors and the timing of any of those risk factors described in our most recent Annual Report on Form 10-K and any subsequently filed Quarterly Reports on Form 10-Q. These documents are available through the SEC’s Electronic Data Gathering and Analysis Retrieval System at http://www.sec.gov.

RISK FACTORS

Investing in the securities involves a high degree of risk. You should carefully consider the risk factors described in our Annual Report on Form 10-K for our most recent fiscal year as filed with the SEC on February 12, 2026 (together with any material changes thereto contained in subsequently filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) and those contained in our other filings with the SEC, which are incorporated by reference in this prospectus supplement. These disclosures reflect the Company’s beliefs and opinions as to factors that could materially and adversely affect the Company and its securities in the future. References to past events are provided by way of example only and are not intended to be a complete listing or a representation as to whether or not such factors have occurred in the past or their likelihood of occurring in the future. These risks could materially affect our business, results of operations, or financial condition and cause the value of the securities to decline. You could lose all or part of your investment.

USE OF PROCEEDS

The Shares are issuable upon exercise of the Warrant. We will receive up to an aggregate of approximately $2.2 million of proceeds upon exercise of the Warrant to the extent the Warrant is fully vested and exercised for cash. The exercise of the Warrant is dependent on the trading price of our common stock exceeding the exercise price of the Warrant. To the extent that any portion of the Warrant is exercised on a “cashless basis,” the amount of cash we would receive from the exercise of the Warrant will decrease, or we may not receive any cash proceeds at all. We do not expect to rely on the cash exercise of the Warrant to fund our operations. We currently intend to use such proceeds, if any, for working capital and general corporate purposes.
 

DIVIDEND POLICY

We have never declared or paid cash dividends on our capital stock. We currently intend to retain our future earnings, if any, for use in our business and therefore do not anticipate paying cash dividends in the foreseeable future. Payment of future dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash needs, and plans for expansion.
 

DILUTION

If you invest in shares of our common stock pursuant to exercise of the Warrant, your interest will be diluted to the extent of the difference between the exercise price per share of our common stock and the net tangible book value per share of our common stock after this offering. We calculate net tangible book value per share by dividing our net tangible assets (tangible assets less total liabilities) by the number of shares of our common stock issued and outstanding.

Our net tangible book value at March 31, 2026 was $(31.3) million, or $(1.02) per share, based on 30,776,689 shares of our common stock outstanding as of such date. After giving effect to the assumed sale by us of 650,000 shares of our common stock upon the cash exercise of the Warrant at $3.4019 per share, our net tangible book value at March 31, 2026 would have been $(29.0) million, or $(0.92) per share. This represents an immediate increase in pro forma net tangible book value of $0.10 per share to existing stockholders and an immediate dilution of $4.32 per share to the holder exercising the Warrant. The following table illustrates this per share dilution.

The table and calculations above are based on 30,776,689 shares of our common stock outstanding as of March 31, 2026, and exclude the following:

DESCRIPTION OF SECURITIES TO BE REGISTERED

For a description of the common stock underlying the Warrant, please see “Description of Common Stock We May Offer” in the accompanying prospectus. The common stock is issuable upon exercise of the Warrant, which has material terms as summarized below.

Exercise Price: The Warrant has an exercise price of $3.4019 per share of our common stock.

Exercisability. The Warrant is exercisable in respect of 500,000 shares of common stock on or after the date of issuance and until the tenth anniversary of the date of issuance. The Warrant will become exercisable in respect of an additional 150,000 shares of common stock only if the Company closes on the Additional Commitment Amount and will remain exercisable in respect of such shares until the tenth anniversary of such date. Upon the holder’s exercise of the Warrant, we will issue the shares of common stock within two business days of our receipt of notice of exercise and payment of the aggregate exercise price. The holder of the Warrant may exercise the Warrant to purchase shares of our common stock on or before the applicable termination date by delivering an exercise notice, appropriately completed and duly signed, and payment of the exercise price for the number of shares for which such Warrant is being exercised in cash or by instructing the Company to withhold a number of shares underlying such Warrant with an aggregate fair market value equal to the exercise price.

Automatic Cashless Exercise. To the extent the Warrants have not been exercised in full prior to the earlier of (i) the occurrence of the expiration of the Warrants, and (ii) the date on which a sale of the Company is consummated, any portions of the Warrants that remains unexercised on such date will be deemed to have been exercised automatically pursuant to a cashless exercise, in whole (and not in part), on the business day immediately preceding such date; provided, that such an automatic cashless exercise will not occur if the per share fair market value of a Warrant share is less than the exercise price per Warrant share.

Adjustments upon Reorganizations, Reclassifications, etc. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.

Anti-Dilution Adjustments. The exercise price of the Warrants is subject to adjustment upon certain capital reorganizations, reclassifications, and other similar transactions.

Transferability. Subject to applicable laws, the Warrant may be offered for sale, sold, transferred or assigned without our consent.

Rights as a Stockholder. Except as described below or by virtue of the holder’s ownership of our common stock, the holder of the Warrant does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the Warrant or portion thereof.

Limit on Exercise. The exercisability or exchangeability of the Warrant may be limited in certain circumstances if, after giving effect to such exercise or exchange, the holder or any of its affiliates would beneficially own (as determined pursuant to Section 13(d) of the Exchange Act) more than 9.99% of our total common stock issued and outstanding.

PLAN OF DISTRIBUTION

Background

On January 13, 2026, the Company entered into a five-year credit facility with Perceptive providing up to $60.0 million in total borrowings pursuant to the Credit Agreement. At closing, we drew $50.0 million and used a portion of the proceeds to repay our existing debt, resulting in net proceeds of approximately $6.0 million after repayment of our prior debt and certain related transaction fees. This credit facility includes an option to access an additional $10.0 million through the first quarter of 2027, subject to the achievement of a certain revenue milestone. This facility also establishes TTM revenue covenants aligned with our current operating trajectory, including $68.5 million for the quarter ended March 31, 2026, $69.0 million for the quarter ending June 30, 2026, and $73.0 million for the year ending December 31, 2026. The TTM revenue covenant is $69.0 million for the second quarter ending June 30, 2026, and $73.0 million for the full year 2026.

The Shares are issuable upon exercise of the Warrant issued to Perceptive as consideration for entering into the Credit Agreement. Of the 650,000 Shares issuable under the Warrant, the Warrant is currently exercisable in respect of 500,000 Shares and the remainder will vest and become exercisable in respect of 150,000 Shares only if the Company closes on the Additional Commitment Amount. The offer of the Shares issuable upon exercise of the Warrant is registered pursuant to our shelf registration statement on Form S-3 (File Number 333-294790) to which this prospectus supplement relates.

The foregoing description of the Credit Agreement and the Warrant is only a summary, does not purport to be complete and is qualified in its entirety by reference to the Credit Agreement and the Warrant, copies of which were attached as Exhibit 10.1 to our Current Report on Form 8-K filed with the SEC on January 13, 2026 and Exhibit 4.1 to our Current Report on Form 8-K filed with the SEC on June 5, 2026.

We currently anticipate that closing of the sale of the Shares pursuant to this prospectus supplement will take place from time to time upon the vesting and exercise of the Warrant.

ASX Listing Rules

ASX Listing Rules may impose limits on the number of shares that we can issue without shareholder approval. In particular, Listing Rule 7.1 provides that a company may not, without prior shareholder approval, issue, or agree to issue, an amount of equity securities in any twelve-month period exceeding 15% of the number of shares outstanding at the commencement of that 12-month period (“Listing Capacity”). At the time we entered the Credit Agreement, we did not have the Listing Capacity to issue the Warrant absent stockholder approval. At our 2026 Annual Meeting of Stockholders on June 3, 2026, our stockholders approved the issuance of the Warrant for purposes of ASX Listing Rule 7.1, permitting the exercise of the Warrant by Perceptive and its assigns, and issuance of shares of common stock thereupon. Because the stockholders approved the issuance of the Warrant, its issuance is not counted against our Listing Capacity.

Listing and Transfer Agent

Our common stock is listed on The Nasdaq Stock Market LLC and trades under the symbol “RCEL.” The transfer agent of our common stock is Computershare Trust Company, N.A. Our CDIs are listed on the ASX under the symbol “AVH” with five CDIs being equivalent to one share of our common stock.
 

LEGAL MATTERS

The validity of the issuance of the securities offered hereby will be passed upon for us by K&L Gates LLP, Charlotte, North Carolina.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risk factors described in our Annual Report on Form 10-K for our most recent fiscal year (together with any material changes thereto contained in subsequently filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) and those contained in our other filings with the SEC, which are incorporated by reference in this prospectus and any accompanying prospectus supplement.

The prospectus supplement applicable to each type or series of securities we offer may contain a discussion of risks applicable to the particular types of securities that we are offering under that prospectus supplement. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the caption “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained in the prospectus supplement or appearing or incorporated by reference in this prospectus. These risks could materially affect our business, results of operations or financial condition and cause the value of our securities to decline. You could lose all or part of your investment.

USE OF PROCEEDS

Unless specified otherwise in the applicable prospectus supplement, we expect to use the net proceeds we receive from the sale of the securities offered by this prospectus for general corporate purposes, which may include, among other things:

The precise amount and timing of the application of such proceeds will depend upon our funding requirements and the availability and cost of other capital. Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of short- term indebtedness.

DESCRIPTION OF COMMON STOCK WE MAY OFFER

We are a Delaware corporation. The rights of our stockholders are governed by the Delaware General Corporation Law, or the DGCL, and our amended certificate of incorporation (the “Certificate”) and our amended and restated bylaws (the “Bylaws”). The following summary of some of the material terms, rights and preferences of our capital stock is not complete. You should read our Certificate and our Bylaws for more complete information. In addition, you should be aware that the summary below does not give full effect to the terms of the provisions of statutory or common law which may affect your rights as a stockholder.

Common Stock

General

Our Certificate authorizes the issuance of up to 200,000,000 shares of common stock, $0.0001 par value per share. Our authorized but unissued shares of common stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded.

Voting Rights

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, in an uncontested election, holders of a majority of the voting shares are able to elect all of the directors.

Dividends

Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds. Dividends may be paid in cash, in property or in shares of common stock. Declaration and payment of any dividend will be subject to the discretion of our board of directors. The time and amount of dividends will be dependent upon our financial condition, operations, cash requirements and availability, debt repayment obligations, capital expenditure needs, restrictions in our debt instruments, industry trends, the provisions of Delaware law affecting the payment of distributions to stockholders and any other factors our board may consider relevant.

Liquidation

In the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Rights and Preferences

Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences, and privileges of the 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 preferred stock that we may designate in the future.

Fully Paid and Non-assessable

All outstanding shares of our common stock are fully paid and non-assessable.

Annual Stockholder Meetings

Our Certificate and Bylaws provide that annual stockholder meetings will be held at a date, place (if any) and time, as exclusively selected by our board of directors. To the extent permitted under applicable law, we may but are not obligated to conduct meetings by remote communications, including by webcast.

Preferred Stock

Our board of directors has the authority to issue up to 10,000,000 shares of preferred stock, par value $0.0001 per share, in one or more series, each of which will have such distinctive designation or title as shall be determined by our board of directors prior to the issuance of any shares thereof. Preferred stock will have such voting powers, whole or limited, or no voting powers, and such preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated in such resolution or resolutions providing for the issue of such class or series of preferred stock as may be adopted from time to time by our board of directors prior to the issuance of any shares thereof. The designations, powers, rights and preferences of our preferred stock could include voting rights, dividend rights, dissolution rights, conversion rights, exchange rights, redemption rights, liquidation preferences, and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock. The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing change in our control or other corporate action. No shares of our preferred stock are currently issued and outstanding.

Anti-Takeover Effects of Provisions of the Certificate and Bylaws and DGCL

Some provisions of the DGCL, our Certificate and Bylaws could make the following transactions difficult: (i) acquisition of the Company by means of a tender offer; (ii) acquisition of the Company by means of a proxy contest or otherwise; or (iii) removal of incumbent officers and directors of the Company. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interest, including transactions that might result in a premium over the market price for our common stock.

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of the Company to first negotiate with the Board.

Delaware Anti-Takeover Statute

The Company is subject to Section 203 of the DGCL, which prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a publicly-held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock, and a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by our board of directors, such as discouraging takeover attempts that might result in a premium over the market price of the Company’s common stock.

However, the above provisions of Section 203 do not apply if:

Stockholders may, by adopting an amendment to our Certificate or Bylaws, elect for the corporation not to be governed by Section 203, effective 12 months after adoption. Neither our Certificate nor our Bylaws exempts us from the restrictions imposed under Section 203. It is anticipated that the provisions of Section 203 may encourage companies interested in acquiring us to negotiate in advance with our board.

Special Stockholder Meetings

The Bylaws provide that a special meeting of stockholders (1) may be called at any time by the order of a majority of our entire board of directors, the Chairman of the Board, the Chief Executive Officer or the President (in the absence of a chief executive officer), and (2) shall be called by the Secretary upon the written request of the holders of record of at least twenty-five percent (25%) of the outstanding shares of common stock of the Company.

Requirements for Advance Notification of Stockholder Nominations and Proposals

The Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors.

Composition of our Board of Directors; Election and Removal of Directors; Filling Vacancies

The Company’s board of directors consists of one or more directors. In any uncontested elections of directors, a director nominee for our board of directors of the Company will be elected by the plurality of the votes cast with respect to such director at a meeting at which a quorum is present.

In a contested election, a plurality voting standard will apply to director elections. The directors of the Company are elected until the expiration of the term for which they are elected and until their respective successors are duly elected and qualified.

The directors of the Company may be removed by the affirmative vote of the holders of at least a majority of the Company’s then-outstanding common stock. Furthermore, any vacancy on the Company’s board of directors, however occurring, including a vacancy resulting from an increase in the size of the board, may be filled only by a majority vote of our board of directors then in office, even if less than a quorum, or by the sole remaining director.

Amendment of the Certificate and Bylaws

The Certificate may be amended in any manner permitted under the DGCL and the Bylaws may be amended by the holders of at a majority of the voting power of the then outstanding voting stock or by our board of directors.

Limitations of Liability and Indemnification Matters

Each of the Certificate and Bylaws provide that the Company is required to indemnify its directors and officers to the fullest extent permitted by Delaware law. The Bylaws also obligates the Company to advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding upon delivery to the Company of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision, from which there is no further right to appeal, that such indemnitee is not entitled to be indemnified for such expenses.

The Company may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent or another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Securities Exchange Listings

Shares of our common stock are listed on The Nasdaq Stock Market LLC under the symbol “RCEL.” Our Chess Depositary Interests (“CDIs”) are quoted on the Australian Securities Exchange Ltd (“ASX”) under the ticker code, “AVH”. One share of common stock on Nasdaq is equivalent to five CDIs on the ASX.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A, and its address is 250 Royall St., Canton, Massachusetts 02021.

DESCRIPTION OF PREFERRED STOCK WE MAY OFFER

We may offer shares of our preferred stock from time to time, in one or more series of preferred stock. Pursuant to our Certificate, we have the authority to issue 10,000,000 shares of preferred stock, $0.0001 par value. As of March 31, 2026, we had no shares of preferred stock outstanding. Our board of directors may, without action by stockholders, issue one or more series of preferred stock. The board may determine for each series the number of shares, designation, relative voting rights, dividend rates, liquidation and other rights, preferences, and limitations. The issuance of preferred stock could adversely affect the voting power of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation. The issuance could decrease the market price of our common stock. The issuance of preferred stock also could delay, deter, or prevent a change of control of the Company.

We have summarized material provisions of the preferred stock in this section. This summary is not complete. If we offer preferred stock, we will file a form of certificate of designation designating the rights and preferences of the preferred stock with the SEC prior to any issuance of preferred stock, and you should read such certificate of designation for provisions that may be important to you.

The certificate of designation and prospectus supplement relating to any series of preferred stock we are offering will include specific terms relating to the offering. These terms will include some or all of the following:

Any shares of preferred stock we issue will, at the time of issuance, be fully paid and non-assessable.

DESCRIPTION OF WARRANTS WE MAY OFFER

We may issue warrants to purchase common stock or preferred stock. We may issue warrants independently in an offering or together with any other securities we offer under a prospectus supplement. Warrants sold with other securities may be attached to or separate from the other securities. We will issue warrants under one or more warrant agreements between us and a warrant agent which will be named in the prospectus supplement.

We have summarized material provisions of the warrants and the warrant agreements below. This summary is not complete and will only be complete when described in any prospectus supplement. We will file the form of any warrant agreement with the SEC, and you should read the warrant agreement for provisions that may be important to you.

A prospectus supplement relating to any warrants that we are offering will include specific terms relating to the offering. These terms will include some or all of the following:

Exercise of Warrants

Holders may exercise warrants as described in the prospectus supplement relating to the warrants being offered. Each warrant will entitle the holder of the warrant to purchase for cash at the exercise price provided in the applicable prospectus supplement the principal amount of shares of common stock or shares of preferred stock being offered. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of common stock or shares of preferred stock purchasable upon the exercise of the warrants. If less than all of the warrants represented by the warrant certificate are exercised, we will issue a new warrant certificate for the remaining warrants.

Holders may exercise warrants at any time up to the close of business on the expiration date provided in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants are void.

Prior to the exercise of their warrants, holders of warrants will not have any of the rights of holders of the securities subject to the warrants.

Modifications

We may amend the warrant agreements and the warrants without the consent of the holders of the warrants to cure any ambiguity, to cure, correct or supplement any defective or inconsistent provision, or in any other manner that will not materially and adversely affect the interests of holders of outstanding warrants.

We may also modify or amend certain other terms of the warrant agreements and the warrants with the consent of the holders of not less than a majority in number of the then outstanding unexercised warrants affected. Without the consent of the holders affected, however, no modification or amendment may:

Enforceability of Rights

The warrant agent, as described in the prospectus supplement, will act solely as our agent in connection with the warrants and will not assume any obligations or relationship of agency or trust for or with any warrant holder. The warrant agent will not have any duty or responsibility if we default under the warrant agreements or the warrant certificates. A warrant holder may, without the consent of the warrant agent, enforce by appropriate legal action on its own behalf the holder’s right to exercise the holder’s warrants.

DESCRIPTION OF UNITS WE MAY OFFER

We may also issue units comprised of one or more of the other securities described above in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also a 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 before a specified date.

We have summarized material provisions of the units and the unit agreements below. This summary is not complete and will be complete as described in a prospectus supplement. We will file the form of any unit agreement with the SEC, and you should read the unit agreement for provisions that may be important to you.

A prospectus supplement relating to any units we are offering will include specific terms relating to the offering. These terms will include some or all of the following:

CHESS DEPOSITARY INTERESTS

Any shares of common stock, or preferred stock, warrants or units that we offer that are otherwise convertible or exercisable into common stock may be issued in Australia in the form of CDIs or securities convertible or exchangeable into CDIs. If an offering includes such securities, it will be further described in a prospectus supplement.

Our CDIs are quoted on the ASX under the ticker code, “AVH”. One share of common stock on Nasdaq is equivalent to five CDIs on the ASX.

PLAN OF DISTRIBUTION

We may from time to time offer and sell, separately or together, some or all of the securities covered by this prospectus. Registration of the securities covered by this prospectus does not mean, however, that the securities will be offered or sold.

The securities covered by this prospectus may be sold from time to time, at market prices prevailing at the time of sale, at prices related to market prices, at a fixed price or prices subject to change or at negotiated prices, by a variety of methods, including the following:

At any time a particular offer of securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth:

Any such required prospectus supplement of which this prospectus is a part will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of securities covered by this prospectus.

Underwriters, broker-dealers or agents may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us, from the purchasers of the securities or from both the sellers and the purchasers. The compensation received may be in excess of customary discounts, concessions or commissions. Any underwriters, dealers, agents or other investors participating in the distribution of the securities may be deemed to be “underwriters,” as that term is defined in the Securities Act, and compensation and profits received by them on sale of the securities may be deemed to be underwriting commissions, as that term is defined in the rules promulgated under the Securities Act.

If dealers are utilized in the sale of offered securities, we will sell such offered securities to the dealers as principals. The dealers may then resell such offered securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction.

We may sell securities from time to time to one or more underwriters, who would purchase the securities as principal for resale to the public, either on a firm-commitment or best-efforts basis. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. If we sell securities to underwriters, we may execute an underwriting agreement with them at the time of sale and will name them in the applicable prospectus supplement. The underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters with respect to a sale of offered securities will be obligated to purchase all such offered securities of a series if any are purchased. We may grant to the underwriters options to purchase additional offered securities, to cover over-allotments, if any, at the public offering price (with additional underwriting discounts or commissions), as may be set forth in the applicable prospectus supplement. If we grant any over-allotment option, the terms of such over-allotment option will be set forth in the prospectus supplement relating to such offered securities. In connection with such sales, underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agents. Underwriters may resell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from purchasers for whom they may act as agents. The prospectus supplement will include any required information about underwriting compensation we pay to underwriters, and any discounts, concessions or commissions underwriters allow to participating dealers, in connection with an offering of securities.

If so indicated in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase offered securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

Underwriters, broker-dealers or agents may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters, dealers, agents and remarketing firms may be required to make. Underwriters, broker-dealers and agents, as well as their respective affiliates, may be customers of, engage in transactions with, or perform services in the ordinary course of business for us and/or our affiliates.

Each series of securities will be a new issue of securities and will have no established trading market other than our common stock which is listed on The Nasdaq Stock Market LLC and our CDIs which are listed on the ASX. Any common stock sold will be listed on The Nasdaq Stock Market LLC, upon official notice of issuance. Any CDIs sold will be listed on the ASX in accordance with the rules and regulations of the ASX. The securities, other than our common stock, may or may not be listed on a national securities exchange or other organized market. Any underwriters to whom securities are sold by us for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity or trading market for any of the securities.

Certain persons participating in the offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. We make no representation or prediction as to the direction or magnitude of any effect that such transactions may have on the price of the securities.

LEGAL MATTERS

The validity of the issuance of the shares of common stock, preferred stock, warrants, or units, as applicable, offered hereby will be passed upon for us by K&L Gates LLP, 925 Fourth Avenue, Seattle, WA 98104. Additional legal matters may be passed on for us, or any underwriters, dealers or agents, by counsel whom we will name in the applicable prospectus supplement.
