SELLING SECURITY HOLDER

This prospectus supplement covers the resale from time to time by the selling security holder identified in the table below, including its pledgees, donees, transferees, assigns or other successors in interest, of up to an aggregate of 22,424,755 ADSs. The ADSs and/or the Ordinary Shares that they represent that are registered for resale hereunder are issuable upon conversion of certain 9.25% Convertible Senior PIK Notes due 2028 (“Convertible Notes”) issued by the Company to the selling security holder named herein, at a purchase price equivalent to 97% of the principal amount of the Convertible Notes. The Convertible Notes were issued in a transaction exempt from registration requirements of the Securities Act. We are registering the resale of the ADSs as required by the Investment Agreement, dated May 9, 2023 by and between the Company and the selling security holder. The selling security holder has not received any of our securities as compensation for underwriting services. We will not receive any proceeds from the resale of the ADSs by the selling security holder.

The selling security holder identified in the table below may from time to time offer and sell under this prospectus any or all of the ADSs described under the column “ADSs Being Offered in this Offering” in the table below. The table below has been prepared based upon information furnished to us by the selling security holder as of the dates represented in the footnotes accompanying the table. The selling security holder identified below may have sold, transferred or otherwise disposed of some or all of the Convertible Notes since the date on which the information in the following table is presented in transactions exempt from or not subject to the registration requirements of the Securities Act. Information concerning the selling security holder may change from time to time and, if necessary, we will amend or supplement this prospectus accordingly and as required.

The following table and footnote disclosure following the table sets forth the name of the selling security holder and the number of Ordinary Shares, including any ADSs representing Ordinary Shares (together, “Shares”) beneficially owned by the selling security holder before this offering. The number of Shares reflected are those beneficially owned, as determined under applicable rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under applicable SEC rules, beneficial ownership includes any Shares as to which a person has sole or shared voting power or investment power and any Shares which the person has the right to acquire within 60 days after June 15, 2023 through the conversion of notes. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage.

The number of ADSs reflected in the table as being offered in the offering reflects our good-faith estimate of the maximum number of shares that may be issued upon conversion of the Convertible Notes and, accordingly, assumes that interest thereon is paid semi-annually in-kind through maturity.

We have assumed that all ADSs reflected in the table as being offered in the offering covered by this prospectus supplement will be sold from time to time in this offering. We cannot provide an estimate as to the number of Shares that will be held by the selling security holder upon termination of the offering covered by this prospectus supplement because the selling security holder may offer some, all or none of its ADSs being offered in the offering.

The percentage of shares beneficially owned is based on 592,319,923 Ordinary Shares outstanding as of May 9, 2023.

MARKET AND INDUSTRY DATA

Contained in or incorporated by reference in this prospectus and any applicable prospectus supplement, we reference information and statistics regarding the industries in which we operate, including the dairy industry. We are responsible for these statements included in or incorporated by reference in this prospectus and any applicable prospectus supplement. We have obtained this information and statistics from various independent third-party sources, such as Euromonitor International Limited (“Euromonitor”) and other third-party sources.

Some data and other information contained in or incorporated by reference in this prospectus and any applicable prospectus supplement are also based on our own estimates and calculations, which are derived from our review and interpretation of independent sources. Data regarding the industries in which we compete and our market position and market share within these industries are inherently imprecise and are subject to significant business, economic and competitive uncertainties beyond our control, but we believe they generally indicate size, position and market share within this industry. While we believe such information is reliable, we have not independently verified any third-party information. While we believe our internal company research and estimates are reliable, such research and estimates have not been verified by any independent source.

In addition, assumptions and estimates of our and our industries’ future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause our future performance to differ materially from our assumptions and estimates. As a result, you should be aware that market, ranking and other similar industry data included in or incorporated by reference in this prospectus and any applicable prospectus supplement, and estimates and beliefs based on that data, may not be reliable. We cannot guarantee the accuracy or completeness of any such information contained in or incorporated by reference in this prospectus and any prospectus supplement. Forecasts and other forward-looking information obtained from these sources are subject to the same qualifications and uncertainties as the other forward-looking statements in our Annual Report. See Item 3.D. “Risk Factors—Risks Related to our Business and Industry—Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.”

COMPANY OVERVIEW

Our Company is disrupting the global dairy industry, which Euromonitor estimated generated $631 billion in retail sales in 2022. We are driving this disruption by encouraging consumers to reassess the impacts that their food choices have on the climate and environment. We position our brand to benefit from the trend of consumers choosing plant-based foods as an alternative to animal-based ones. Our products have broad consumer appeal, which has allowed us to penetrate multiple classes of trade in multiple geographies. As of December 31, 2022, our product was the number one oatmilk brand in seven of the over 20 countries in which we operate. We believe that we have a long runway of growth ahead of us as consumers continue to seek plant-based alternatives and we continue to expand into new categories and geographies.

We are the world’s original and largest oatmilk company. For over 25 years, we have focused on developing expertise around oats: a global power crop with inherent properties suited for sustainability and human health. Our commitment to oats has resulted in core technical advancements that enabled us to unlock the breadth of the dairy portfolio, including milks, ice cream, yogurt, cooking creams, spreads and on-the-go drinks.

Sustainability is at the core of our business. In general, oatmilk leads to fewer greenhouse gas emissions compared to cow’s milk. Specifically, based on certain product-level calculations we have commissioned in Europe and based on additional studies, we generally see that oatmilk products have a significantly lower climate (CO2 equivalent) impact relative to comparable dairy products.

4

In the historically commoditized dairy category, we have created a brand phenomenon that speaks to emerging consumer priorities, including sustainability and health. Our integrated in-house team of creative, communications and customer relations experts reach consumers in a personal and relatable way. Across many kinds of media, we create thought-provoking, conversation-sparking content to engage people around our mission and drive awareness for our brand. Our company values are communicated not only in the things we say but also in the things we do— such as publishing the climate impact of our products in Europe and the U.S. and launching public campaigns to inspire policy change. The voice, actions, products and values represented by the Oatly brand drive our commercial success and mission.

Our innovation practices are foundational to delivering market-leading products. We are steadfast in our goal of creating excellent products across the full dairy portfolio, from milk, to yogurts, to ice cream. To do so, we leverage clinical studies on human health along with our proprietary production processes and key patented elements, including enzymatic processes, to convert fiber-rich oats into great tasting and healthy products. We believe our product launches in categories such as yogurt and frozen desserts shows the strength of our results-oriented innovation practices and the potential to drive a significant volume shift to plant-based dairy across the full breadth of the dairy portfolio.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We may issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939 (the “Trust Indenture Act”). We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount” (“OID”) for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose all or substantially all of our assets. However, any successor to or acquirer of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.

Events of Default under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 30% in aggregate principal

amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

A holder of the debt securities of any series will have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities, after the applicable grace period.

We will periodically file statements with the trustee regarding our compliance with specified covenants in the indenture.

Modification of Indenture; Waiver

We and the trustee may change an indenture without the consent of any holders with respect to specific matters:

10

In addition, under the indenture, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, debt securities of such series) of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, debt securities of such series) of each holder of any outstanding debt securities affected:

Discharge

Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

11

Form, Exchange and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company, or DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.

At the option of the holder, subject to the terms of the indenture and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indenture and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

Information Concerning the Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indenture at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

12

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

The indenture and the debt securities will be governed by and construed in accordance with the internal laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

DESCRIPTION OF WARRANTS

We may issue and offer warrants under the material terms and conditions described in this prospectus and any accompanying prospectus supplement. The accompanying prospectus supplement may add, update or change the terms and conditions of the warrants as described in this prospectus.

We may issue warrants to purchase our ADSs, ordinary shares represented by ADSs and debt securities, or any combination thereof. Warrants may be issued independently or together with any securities and may be attached to or separate from those securities. The warrants may be issued under warrant or subscription agreements to be entered into between us and a bank or trust company, as warrant agent, all of which will be described in the prospectus supplement relating to the warrants we are offering. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The particular terms of the warrants, the warrant or subscription agreements relating to the warrants and the warrant certificates representing the warrants will be described in the applicable prospectus supplement, including, as applicable:

13

Holders of warrants will not be entitled, solely by virtue of being holders, to vote, to consent, to receive dividends, to receive notice as shareholders with respect to any meeting of shareholders for the election of directors or any other matters, or to exercise any rights whatsoever as a holder of the equity securities purchasable upon exercise of the warrants.

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. The following description sets forth certain general terms and provisions of the units that we may offer pursuant to this prospectus. The particular terms of the units and the extent, if any, to which the general terms and provisions may apply to the units so offered will be described in the applicable prospectus supplement.

We will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, as well as any related free writing prospectuses and the complete unit agreement and any supplemental agreements that contain the terms of the units.

Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

SELLING SECURITY HOLDERS

Information about selling security holders will be set forth in a prospectus supplement, in a post-effective amendment or in filings we will make with the SEC which are incorporated into this prospectus by reference.

16

PLAN OF DISTRIBUTION

We and any selling security holder may sell the securities in one or more of the following ways (or in any combination) from time to time:

The distribution of our securities may be carried out, from time to time, in one or more transactions, including:

A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:

Underwriters may offer and sell the securities at a fixed price or prices, which may be changed, or from time to time at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. We or any selling security holders may, from time to time, authorize agents acting on a best or reasonable efforts basis as our agents to solicit or receive offers to purchase the securities upon the terms and conditions as are set forth in the applicable prospectus supplement. In connection with the sale of securities, underwriters or agents may be deemed to have received compensation from us or any selling security holders in the form of underwriting discounts and may also receive commissions from purchasers of securities for whom they may act as agent.

Underwriters may sell securities to or through dealers, and dealers may receive compensation in the form of discounts or concessions from the underwriters and commissions from the purchasers for whom they may act as agent.

17

Underwriters, dealers and agents who participate in the distribution of securities and their controlling persons may be entitled, under agreements that may be entered into with us to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that the underwriters, dealers or agents and their controlling persons may be required to make in respect of those liabilities.

We or any selling security holders may also make direct sales through subscription rights distributed to our existing shareholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to our shareholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act that stabilize, maintain or otherwise affect the price of the offered securities. If any such activities will occur, they will be described in the applicable prospectus supplement.

One or more selling security holders may utilize this prospectus (and any related prospectus supplement) to make one or more in-kind distributions of the securities to its shareholders, partners or members. To the extent required by applicable law, information about the distribution will be reflected in a prospectus supplement.

ENFORCEMENT OF CIVIL LIABILITIES

We are incorporated and currently existing under the laws of Sweden. In addition, certain of our directors and officers reside outside of the United States, and substantially all of the assets of our subsidiaries are located outside of the United States. As a result, it may be difficult for investors to effect service of process on us or those persons in the United States or to enforce in the United States judgments obtained in U.S. courts against us or those persons based on the civil liability or other provisions of the U.S. securities laws or other laws. In addition, uncertainty exists as to whether the courts of Sweden would:

The United States and Sweden currently do not have a treaty providing for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in Sweden. In order to obtain a judgment that is enforceable in Sweden, the party in whose favor a final and conclusive judgment of the U.S. court has been rendered will be required to file its claim with a court of competent jurisdiction in Sweden. Such party may submit to the Swedish court the final judgment rendered by the U.S. court. This court will have discretion to attach such weight to the judgment rendered by the relevant U.S. court depending on the circumstances. Circumstances that may be relevant to the Swedish court in deciding to give conclusive effect to a final and enforceable judgment of such court in respect of the contractual obligations thereunder without re-examination or re-litigation of the substantive matters adjudicated upon include whether: (i) the court involved accepted jurisdiction on the basis of internationally recognized grounds to accept jurisdiction, (ii) the proceedings before such court are in compliance with principles of proper procedure, (iii) such judgment is not contrary to the public policy of Sweden and (iv) such judgment is not incompatible with a judgment given between the same parties by a Swedish court or with a prior judgment given between the same parties by a foreign court in a dispute concerning the same subject matter and based on the same cause of action, provided such prior judgment fulfils the conditions necessary for it to be given binding effect in Sweden. Swedish courts may deny the recognition and enforcement of punitive damages or other awards. Moreover, a Swedish court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages.

Swedish civil procedure differs substantially from U.S. civil procedure in a number of respects. Insofar as the production of evidence is concerned, U.S. law and the laws of several other jurisdictions based on common law provide for pre-trial discovery, a process by which parties to the proceedings may prior to trial compel the production of documents by adverse or third parties and the deposition of witnesses. Evidence obtained in this manner may be decisive in the outcome of any proceeding. No such pre-trial discovery process exists under Swedish law.

Subject to the foregoing and service of process in accordance with applicable treaties, investors may be able to enforce in Sweden judgments in civil and commercial matters obtained from U.S. federal or state courts. However, no assurance can be given that those judgments will be enforceable. In addition, it is doubtful whether a Swedish court would accept jurisdiction and impose civil liability in an original action commenced in Sweden and predicated solely upon U.S. federal securities laws.

19

Accordingly, we are required to file reports and other information with the SEC, including annual reports on Form 20-F and disclosure furnished under cover of Form 6-K. The SEC maintains a website (www.sec.gov) that contains reports and other information regarding issuers, such as us, that file electronically with the SEC. We also maintain a website (https:// www.oatly.com), from which you can access such reports and other information free of charge as soon as reasonably practicable after such material is electronically filed with, or furnished to, the SEC.

We will send the depositary a copy of all notices of shareholders meetings and other reports, communications and information that are made generally available to shareholders. The depositary has agreed to mail to all holders of ADSs a notice containing the information (or a summary of the information) contained in any notice of a meeting of our shareholders received by the depositary and will make available to all holders of ADSs such notices and all such other reports and communications received by the depositary.
