Albemarle Corporation (“Albemarle”) is offering to exchange, upon the terms and subject to the conditions set forth in this prospectus and the accompanying letter of transmittal, all of its outstanding unregistered Floating Rate Notes due 2022 (the “2022 Restricted Notes”) for an equivalent principal amount of our registered Floating Rate Notes due 2022 (the “2022 Exchange Notes”), and Albemarle Wodgina Pty Ltd, a wholly owned subsidiary of Albemarle (“Wodgina”), is offering to exchange, upon the terms and subject to the conditions set forth in this prospectus and the accompanying letter of transmittal, all of its outstanding unregistered 3.450% Senior Notes due 2029 (the “2029 Restricted Notes”) for an equivalent principal amount of its registered 3.450% Senior Notes due 2029 (the “2029 Exchange Notes”), such offers referred to herein, collectively, as the “exchange offers.” The 2022 Restricted Notes and the 2029 Restricted Notes are collectively referred to as the “Restricted Notes”; the 2022 Exchange Notes and the 2029 Exchange Notes are collectively referred to as the “Exchange Notes”; the 2022 Restricted Notes and the 2022 Exchange Notes are collectively referred to as the “2022 Notes”; and the 2029 Restricted Notes and the 2029 Exchange Notes are collectively referred to as the “2029 Notes”. Wodgina’s obligations under the 2029 Restricted Notes are fully and unconditionally guaranteed on a senior unsecured basis (the “2029 Restricted Notes Guarantee”) by Albemarle, and the 2029 Exchange Notes will be fully and unconditionally guaranteed on a senior unsecured basis (the “2029 Exchange Notes Guarantee” and, together with the 2029 Restricted Notes Guarantee, the “2029 Notes Guarantees”) by Albemarle.

The 2022 Exchange Notes and the 2029 Exchange Notes Guarantee will be Albemarle’s senior unsecured obligations and will rank equally with all of Albemarle’s other existing and future senior indebtedness. The 2029 Exchange Notes will be Wodgina’s senior unsecured obligations and will rank equally with all of Wodgina’s other existing and future senior indebtedness. See “Description of the Exchange Notes”. All references to the 2029 Exchange Notes and 2029 Restricted Notes include references to the related guarantees, as appropriate. See “Description of the Exchange Notes—2029 Exchange Notes Guarantee”.

The exchange offers are subject to customary closing conditions and will expire at 11:59 p.m., New York City time, on July 23, 2020 (the “Expiration Date”), unless extended.

Albemarle and Wodgina issued the Restricted Notes in transactions not requiring registration under the Securities Act of 1933, as amended (the “Securities Act”) and, as a result, their transfer is restricted. Albemarle and Wodgina are making the exchange offers to satisfy your registration rights as a holder of the Restricted Notes and will not receive any proceeds from the exchange offers. The terms of the Exchange Notes are identical in all material respects to the Restricted Notes of the same series, except that the Exchange Notes are registered under the Securities Act and will not contain restrictions on transfer or provisions relating to additional interest, will bear a different CUSIP number from the Restricted Notes of the same series and will not entitle their holders to registration rights. The Exchange Notes, together with any Restricted Notes that are not exchanged in the exchange offer, will be governed by the same indenture, constitute the same class of debt securities for the purposes of such indenture and vote together on all matters.

Each holder of Restricted Notes wishing to accept Exchange Notes in the exchange offers must deliver the Restricted Notes to be exchanged, together with the letter of transmittal that accompanies this prospectus and any other required documentation, to the exchange agent identified in this prospectus. Alternatively, you may effect a tender of Restricted Notes by book-entry transfer into the exchange agent’s account at The Depository Trust Company (“DTC”). All deliveries are at the risk of the holder. You can find detailed instructions concerning delivery in the section called “The Exchange Offers” in this prospectus and in the accompanying letter of transmittal.

Each broker-dealer that receives the Exchange Notes for its own account pursuant to the exchange offers must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes. The letter of transmittal accompanying this prospectus states that, by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of the Exchange Notes received in exchange for the Restricted Notes where such Restricted Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. See “Plan of Distribution.” The Exchange Notes will not be listed on any securities exchange or for quotation through any automated dealer quotation system.

See “Risk Factors” beginning on page 9 for a discussion of risk factors that you should carefully consider before deciding to exchange your Restricted Notes for Exchange Notes.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is June 25, 2020

RISK FACTORS

You should carefully consider the specific risk factors set forth below as well as the other information contained or incorporated by reference in this prospectus before deciding to invest in the Exchange Notes. See Item 1A “Risk Factors” in Albemarle’s Annual Report on Form10-K for the year ended December 31, 2019 and Albemarle’s Quarterly Report on Form10-Q for the quarter ended March 31, 2020. Some factors in this section are “forward-looking statements.” For a discussion of those statements and of other factors for investors to consider, see “Forward-Looking Statements.”

TheCOVID-19 pandemic could have a material adverse effect on Albemarle’s and Wodgina’s results of operations, financial position, and cash flows.

TheCOVID-19 pandemic has created significant uncertainty and economic disruption. The extent to which it impacts our business, results of operations, financial position, and cash flows is difficult to predict and dependent upon many factors over which we have no control. These factors include, but are not limited to, the duration and severity of the pandemic; government restrictions on businesses and individuals; the health and safety of our employees and communities in which we do business; the impact of the pandemic on our customers’ businesses and the resulting demand for our products; the impact on our suppliers and supply chain network; the impact on U.S. and global economies and the timing and rate of economic recovery; and potential adverse effects on the financial markets.

Albemarle has taken, and plans to continue to take, certain measures to maintain financial flexibility, including delaying certain capital expenditure projects and accelerating our cost savings initiative, while still protecting our employees and customers. However, if conditions caused by theCOVID-19 pandemic worsen and the Albemarle’s earnings and cash flow from operations do not start to recover as contemplated in the Albemarle’s current plans, Albemarle may not be able to maintain compliance with its financial covenants and it will require Albemarle to seek additional amendments to its credit agreements. If Albemarle is not able to obtain such necessary additional amendments, this would lead to an event of default and its lenders could require Albemarle to repay its outstanding debt. In that situation, Albemarle may not be able to raise sufficient debt or equity capital, or divest assets, to refinance or repay the lenders.

Because a significant portion of Albemarle’s operations is conducted through its subsidiaries and joint ventures, Albemarle’s ability to service its debt could be dependent on its receipt of distributions or other payments from its subsidiaries and joint ventures.

A significant portion of Albemarle’s operations is conducted through its subsidiaries and joint ventures. As a result, Albemarle’s ability to service its debt could be dependent on the earnings of our subsidiaries and joint ventures and the payment of those earnings to us in the form of dividends, loans or advances and through repayment of loans or advances from Albemarle. Payments to Albemarle by its subsidiaries and joint ventures will be contingent upon our subsidiaries’ or joint ventures’ earnings and other business considerations and may be subject to statutory or contractual restrictions. In addition, there may be significant tax and other legal restrictions on the ability ofnon-U.S. subsidiaries or joint ventures to remit money to Albemarle.

Payment on Exchange Notes will be structurally subordinated to indebtedness of Albemarle’s subsidiaries and, in the case of the 2029 Exchange Notes, Wodgina’s joint venture interest.

The Exchange Notes will be structurally subordinated in right of payment to all existing and future debt and other liabilities, including trade payables, of Albemarle’s subsidiaries (other than, in the case of the 2029 Exchange Notes, Wodgina) and joint ventures and the claims of creditors of those subsidiaries and joint ventures, including trade creditors, will have priority as to the assets of those subsidiaries and joint ventures. In addition, the indenture under which the Exchange Notes will be issued will permit these subsidiaries and joint ventures to incur additional indebtedness, subject to certain limitations.

The 2029 Exchange Notes will be obligations of Wodgina and will be guaranteed only by Albemarle and not by any of Albemarle’s other subsidiaries. Wodgina is a wholly owned indirect subsidiary of Albemarle. Wodgina’s cash flow and ability to make payments on the 2029 Exchange Notes could be dependent upon the earnings it derives from the production from the joint venture. Absent income received from sales of its share of

9

production from the joint venture, Wodgina’s ability to service the 2029 Exchange Notes could be dependent upon the earnings of our subsidiaries and other joint ventures and the payment of those earnings to Wodgina in the form of equity, loans or advances and through repayment of loans or advances from Wodgina.

Wodgina and WLPL, as the parties to the Joint Venture, have announced on October 31, 2019 that production of spodumene from the Wodgina Project will be idled until market demand supports bringing the Wodgina Project back into production.

Wodgina’s obligations in respect of the Joint Venture are guaranteed by Albermarle. Further, under the Joint Venture pursuant to a deed of cross security between Wodgina, WLPL and the Manager, each of Wodgina and WLPL have granted security to each other and the Manager for the obligations each of Wodgina and WLPL have to each other and to the Manager. The claims of WLPL, the Manager and other secured creditors of Wodgina will have priority as to the assets of Wodgina over the claims of holders of the 2029 Exchange Notes.

As of March 31, 2020, Albemarle had consolidated total debt of approximately $3.14 billion, of which $1.46 billion) is indebtedness of Albemarle’s subsidiaries (or $1.10 billion) excluding Wodgina).

The terms of the indenture and the Exchange Notes provide only limited protection against significant corporate events and other actions the issuers and the guarantor may take that could adversely impact your investment in the Exchange Notes.

While the indenture and the Exchange Notes contain terms intended to provide protection to the holders of the Exchange Notes upon the occurrence of certain events involving significant corporate transactions, such terms are limited and may not be sufficient to protect your investment in the Exchange Notes.

The definition of the term “Change of Control Triggering Event” (as defined in “Description of the Exchange Notes—Offer to Repurchase Upon Change of Control Triggering Event”) does not cover a variety of transactions (such as acquisitions by us or recapitalizations) that could negatively affect the value of your Exchange Notes. If Albemarle or Wodgina were to enter into a significant corporate transaction that would negatively affect the value of the Exchange Notes but would not constitute a Change of Control Triggering Event, the issuers would not be required to offer to repurchase your Exchange Notes prior to their maturity.

Furthermore, the indenture for the Exchange Notes does not:

As a result of the foregoing, when evaluating the terms of the Exchange Notes, you should be aware that the terms of the indenture and the Exchange Notes do not restrict Albemarle’s and Wodgina’s ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events that could have an adverse impact on your investment in the Exchange Notes.

10

Changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect the cost of financing and the market price of the Exchange Notes.

Credit rating agencies rate debt securities on factors that include operating results, actions that the issuers take, their view of the general outlook for our industry and their view of the general outlook for the economy. Actions taken by the rating agencies can include maintaining, upgrading, or downgrading the current rating or placing the issuers on a watch list for possible future downgrading. Downgrading the credit rating of each issuer’s debt securities or placing them on a watch list for possible future downgrading would likely increase each issuer’s cost of financing, limit their access to the capital markets and have an adverse effect on the market price of their securities.

Borrowings under a portion of Albemarle’s debt facilities, including the $1.2 billion unsecured credit facility (the “New Credit Facility”) and its $1.0 billion revolving unsecured credit facility (the “Revolving Credit Facility”), bear interest at floating rates, and are subject to adjustment based on the ratings of our senior unsecured long-term debt. The downgrading of any of Albemarle’s ratings or an increase in any of the benchmark interest rates would result in an increase of the interest expense on its variable rate borrowings.

The instruments governing the issuers’ indebtedness do not limit acquisitions and allow the issuers to incur additional indebtedness, including indebtedness in relation to acquisitions.

Albemarle has historically expanded its business primarily through acquisitions. A part of Albemarle’s business strategy is to continue to grow through acquisitions that complement and expand its distribution network. The indenture governing the Exchange Notes, and the terms of the issuers’ other indebtedness, do not limit the number or scale of acquisitions that the issuers may complete. Because the consummation of acquisitions and integration of acquired businesses involves significant risk, this means that holders of the Exchange Notes will be subject to the risks inherent in our acquisitive strategy.

In addition, the indenture governing the Exchange Notes described in this prospectus does not restrict Albemarle’s or Wodgina’s ability to incur additional unsecured indebtedness and subject to some limitations on Albemarle (but not Wodgina), permits Albemarle and Wodgina to incur secured indebtedness. The Exchange Notes will be effectively subordinated to any secured indebtedness the issuers may incur to the extent of the value of the collateral securing such indebtedness. Each of the New Credit Facility and the Revolving Credit Facility does limit the amount of consolidated funded debt (as defined in the credit agreements governing such facilities) that the issuers can incur, insofar as we must comply with financial covenants limiting the maximum net leverage ratio that Albemarle is permitted to maintain to 4.00 times Consolidated EBITDA (as defined in such credit agreements) for the fiscal quarter ending June 30, 2020; 4.50 times Consolidated EBITDA for the fiscal quarters through September 30, 2021; 4.00 times Consolidated EBITDA for the fiscal quarters through December 31, 2021; and 3.50 times Consolidated EBITDA for the fiscal quarters thereafter.

The issuers may not have sufficient funds to purchase Exchange Notes upon a Change of Control Triggering Event.

If there is a Change of Control Triggering Event under the terms of the indenture governing the Exchange Notes, each holder of Exchange Notes of a series may require the applicable issuer to purchase all or a portion of their Exchange Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, up to but not including the date of purchase. In order to purchase any outstanding Exchange Notes, the issuers might have to refinance their outstanding indebtedness, which the issuers might not be able to do. Even if the issuers were able to refinance their other indebtedness, any financing might be on terms unfavorable to the issuers. In addition, each of the Revolving Credit Facility and the New Credit Facility provides that the occurrence of certain kinds of change of control events will constitute a default under the applicable facility. The issuers cannot assure you that they will have the financial ability to purchase outstanding Exchange Notes upon the occurrence of a change of control. See “Description of the Exchange Notes—Offer to Repurchase Upon Change of Control Triggering Event.”

11

There may be no public trading market for the Exchange Notes.

The issuers have not applied and do not intend to apply for listing of the Exchange Notes on any securities exchange or any automated quotation system. As a result, a market for the Exchange Notes may not develop or, if one does develop, it may not be maintained. If an active market for the Exchange Notes fails to develop or be sustained, the trading price and liquidity of the Exchange Notes could be adversely affected.

If you are able to resell your Exchange Notes, many other factors may affect the price you receive, which may be lower than you believe to be appropriate.

If you are able to resell your Exchange Notes, the price you receive will depend on many other factors that may vary over time, including:

As a result of these factors, you may only be able to sell your Exchange Notes at prices below those you believe to be appropriate, including prices below the price you paid for them.

Any insolvency proceedings with respect to Wodgina will be governed by Australian insolvency laws, which are different from the insolvency laws of the United States and certain other jurisdictions.

The insolvency laws applicable in Australia are different from the insolvency laws of the United States and certain other jurisdictions, in particular, the voluntary administration procedure under the Corporations Act 2001 (Cth) of Australia (the “Corporations Act”), which provides for the potentialre-organization of an insolvent company, differs significantly from Chapter II of the U.S. Bankruptcy Code. If Wodgina becomes insolvent, the treatment and ranking of holders of the 2029 Exchange Notes, its other creditors and shareholders under Australian law may be different than the treatment and ranking of holders of the 2029 Exchange Notes, its other creditors and shareholders if it were subject to the bankruptcy laws of the United States or certain other jurisdictions. For instance, the High Court of Australia has ruled that shareholders may, in certain circumstances, rank alongside unsecured creditors in awinding-up where shareholders have an independent damages claim against the debtor company arising out of the purchase of their shares.

You may be unable to effect service of process or enforce judgments obtained in U.S. courts against Wodgina or its directors and executive officers.

Wodgina is a corporation organized under the laws of Australia. Additionally, some of the directors and executive officers of Wodgina reside, and substantially all of the assets of such persons are located, outside the United States. As a result, it may not be possible for investors to effect service of process for a lawsuit within the United States upon such persons, including with respect to matters arising under the Securities Act, or to enforce against any of them, judgments innon-U.S. courts obtained in courts of the United States predicated upon, among other things, the civil liability provisions of the U.S. federal securities laws.

Additionally, there is doubt as to the enforceability in Australia, in original actions or in actions for enforcement of judgments of U.S. courts, of civil liabilities based on U.S. federal securities laws. Also, judgments of U.S. courts (whether or not such judgments relate to U.S. federal securities laws) will not be enforceable in Australia in certain other circumstances. See “Enforcement of Civil Liabilities.”

12

The amount of interest payable on the 2022 Exchange Notes is set only once per interest period based on the three-month LIBOR rate on the interest determination date, which rate may fluctuate substantially.

In the past, the level of the three-month LIBOR rate has experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the three-month LIBOR rate are not necessarily indicative of future levels. Any historical upward or downward trend in the three-month LIBOR rate is not an indication that the three-month LIBOR rate is more or less likely to increase or decrease at any time during an interest period (as described in “Description of the Exchange Notes”), and you should not take the historical levels of the three-month LIBOR rate as an indication of its future performance. You should further note that, although the actual three-month LIBOR rate on an interest payment date or at other times during an interest period may be higher than the three-month LIBOR rate on the applicable interest determination date, you will not benefit from the three-month LIBOR rate at any time other than on the interest determination date for such interest period. As a result, changes in the three-month LIBOR rate may not result in a comparable change in the market value of the 2022 Exchange Notes. Increases in the three-month LIBOR rate as of any interest determination date will require us to make higher interest payments on the 2022 Exchange Notes.

Uncertainty relating to the calculation of LIBOR and other reference rates and their potential discontinuance may materially adversely affect the value of the 2022 Exchange Notes.

National and international regulators and law enforcement agencies have conducted investigations into a number of rates or indices which are deemed to be “reference rates.” Actions by such regulators and law enforcement agencies may result in changes to the manner in which certain reference rates are determined, their discontinuance, or the establishment of alternative reference rates. In particular, on July 27, 2017, the Chief Executive of the U.K. Financial Conduct Authority (the “FCA”), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021. Such announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. Notwithstanding the foregoing, it appears highly likely that LIBOR will be discontinued or modified by 2021.

At this time, it is not possible to predict the effect that these developments, any discontinuance, modification or other reforms to LIBOR or any other reference rate, or the establishment of alternative reference rates may have on LIBOR, other benchmarks or floating rate debt securities, including the 2022 Exchange Notes. Uncertainty as to the nature of such potential discontinuance, modification, alternative reference rates or other reforms may materially adversely affect the trading market for securities linked to such benchmarks, including the 2022 Exchange Notes. Furthermore, the use of alternative reference rates or other reforms could cause the interest rate calculated for the 2022 Exchange Notes to be materially different than expected.

If it is determined that LIBOR has been discontinued and an alternative reference rate for three-month LIBOR is used as described in “Description of the Exchange Notes—2022 Exchange Notes—Interest”, Albemarle’s (or its designee, which may be the calculation agent, a successor calculation agent, or such other designee of Albemarle’s (any of such entities, a “Designee”)) may make certain adjustments to such rate, including applying a spread thereon or with respect to the business day convention, interest determination dates and related provisions and definitions, to make such alternative reference rate comparable to three-month LIBOR, in a manner that is consistent with industry-accepted practices or applicable regulatory or legislative actions or guidance for such alternative reference rate. See “Description of the Exchange Notes—2022 Exchange Notes—Interest”. Any of the specified methods of determining floating rate alternative reference rates or the permitted adjustments to such rates may result in interest payments on your 2022 Exchange Notes that are lower than or that do not otherwise correlate over time with the payments that would have been made on the 2022 Exchange Notes if published LIBOR continued to be available. Other floating rate debt securities issued by other issuers, by comparison, may be subject in similar circumstances to different procedures for the establishment of alternative reference rates. Any of the foregoing may have a material adverse effect on the amount of interest payable on your 2022 Exchange Notes, or the market liquidity and market value of your 2022 Exchange Notes.

Interest on the 2022 Exchange Notes will be calculated using a Benchmark Replacement selected by us or our Designee if a Benchmark Transition Event occurs.

As described in detail in the section “Description of the Exchange Notes—2022 Exchange Notes—Interest—Effect of Benchmark Transition Event” (the “benchmark transition provisions”), if during the term of the 2022 Exchange Notes, Albemarle (or its Designee) determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to LIBOR, Albemarle (or its Designee) in our sole discretion will select a Benchmark Replacement as the base rate in accordance with the benchmark transition provisions. The Benchmark Replacement will include a spread adjustment and technical, administrative or operational changes described in the benchmark transition provisions may be made to the interest rate determination if Albemarle (or its Designee) determine in our sole discretion they are required.

Albemarle’s interests (or those of its Designee) in making the determinations described above may be adverse to your interests as a holder of the 2022 Exchange Notes. The selection of a Benchmark Replacement, and any decisions made by Albemarle (or its Designee) in connection with implementing a Benchmark Replacement with respect to the 2022 Exchange Notes, could result in adverse consequences to the applicable interest rate on the 2022 Exchange Notes, which could adversely affect the return on, value of and market for such securities. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to LIBOR or that any Benchmark Replacement will produce the economic equivalent of LIBOR.

The Secured Overnight Financing Rate (“SOFR”) is a relatively new market index and as the related market continues to develop, there may be an adverse effect on the return on or value of the 2022 Exchange Notes.

If a Benchmark Transition Event and its related Benchmark Replacement Date occur, then the rate of interest on the 2022 Exchange Notes will be determined using SOFR (unless a Benchmark Transition Event and its related Benchmark Replacement Date also occur with respect to the Benchmark Replacements that are linked to SOFR, in which case the rate of interest will be based on the next-available Benchmark Replacement). In the following discussion of SOFR, when we refer to SOFR-linked notes or debt securities, we mean the 2022 Exchange Notes at any time when the rate of interest on those notes or debt securities is or will be determined based on SOFR.

The Benchmark Replacements specified in the benchmark transition provisions include Term SOFR, a forward-looking term rate which will be based on the Secured Overnight Financing Rate. Term SOFR is currently being developed under the sponsorship of the Federal Reserve Bank of New York (the “NY Federal Reserve”), and there is no assurance that the development of Term SOFR will be completed. If a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to LIBOR and, at that time, a form of Term SOFR has not been selected or recommended by the Federal Reserve Board, the NY Federal Reserve, a committee thereof or successor thereto, then the next-available Benchmark Replacement under the benchmark transition provisions will be used to determine the amount of interest payable on the 2022 Exchange Notes for the next applicable interest period and all subsequent interest periods (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to that next-available Benchmark Replacement).

These replacement rates and adjustments may be selected or formulated by (i) the Relevant Governmental Body (as defined in the benchmark transition provisions) (such as the Alternative Reference Rates Committee of the NY Federal Reserve), (ii) the International Swaps and Derivatives Association, Inc., or (iii) in certain circumstances, us (or our Designee). In addition, the benchmark transition provisions expressly authorize us (or our Designee) to make Benchmark Replacement Conforming Changes with respect to, among other things, the determination of interest periods and the timing and frequency of determining rates and making payments of interest. The application of a Benchmark Replacement and Benchmark Replacement Adjustment, and any implementation of Benchmark Replacement Conforming Changes, could result in adverse consequences to the amount of interest payable on the 2022 Exchange Notes, which could adversely affect the return on, value of and market for the 2022 Exchange Notes. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark that it is replacing.

The NY Federal Reserve began to publish SOFR in April 2018. Although the NY Federal Reserve has also begun publishing historical indicative SOFR going back to 2014, such prepublication historical data inherently involves assumptions, estimates and approximations. You should not rely on any historical changes or trends in SOFR as an indicator of the future performance of SOFR. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates. As a result, the return on and value of SOFR-linked debt securities may fluctuate more than floating rate debt securities that are linked to less volatile rates.

Also, since SOFR is a relatively new market index, SOFR-linked debt securities likely will have no established trading market when issued, and an established trading market may never develop or may not be very liquid. Market terms for debt securities indexed to SOFR, such as the spread over the index reflected in interest rate provisions, may evolve over time, and trading prices of the 2022 Exchange Notes may be lower than those of later-issued SOFR-linked debt securities as a result. Similarly, if SOFR does not prove to be widely used in securities like the 2022 Exchange Notes, the trading price of those securities may be lower than those of debt securities linked to rates that are more widely used. Debt securities indexed to SOFR may not be able to be sold or may not be able to be sold at prices that will provide a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

The NY Federal Reserve notes on its publication page for SOFR that use of SOFR is subject to important limitations, indemnification obligations and disclaimers, including that the NY Federal Reserve may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice. There can be no guarantee that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to you as a holder of 2022 Exchange Notes. If the manner in which SOFR is calculated is changed or if SOFR is discontinued, that change or discontinuance may result in a reduction or elimination of the amount of interest payable on the 2022 Exchange Notes and a reduction in their trading prices.

If you do not properly tender your Restricted Notes, your ability to transfer such outstanding Restricted Notes will be adversely affected and the trading market for such Restricted Notes may be limited.

The issuers will only issue Exchange Notes in exchange for Restricted Notes that are timely received by the exchange agent, together with all required documents, including a properly completed and signed letter of transmittal or properly transferred via book entry in accordance with the procedures described in this prospectus. Therefore, you should allow sufficient time to ensure timely delivery of the Restricted Notes and you should carefully follow the instructions on how to tender your Restricted Notes. Neither the issuers nor the exchange agent is required to tell you of any defects or irregularities with respect to your tender of Restricted Notes. If you do not tender your Restricted Notes or if your tender of Restricted Notes is not accepted because you did not tender your Restricted Notes properly, then, after consummation of the exchange offers, you will continue to hold Restricted Notes that are subject to the existing transfer restrictions. After the exchange offers are consummated, if you continue to hold any Restricted Notes, you may have difficulty selling them because there will be fewer Restricted Notes remaining and the market for such Restricted Notes, if any, will be much more limited than it is currently. In particular, the trading market for unexchanged Restricted Notes could become more limited than the existing trading market for the Restricted Notes and could cease to exist altogether due to the reduction in the amount of the Restricted Notes remaining upon consummation of the exchange offers. A more limited trading market might adversely affect the liquidity, market price and price volatility of such untendered Restricted Notes.

If you are a broker-dealer or participating in a distribution of the Exchange Notes, you may be required to deliver prospectuses and comply with other requirements.

If you tender your Restricted Notes for the purpose of participating in a distribution of the Exchange Notes, you will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the Exchange Notes. If you are a broker-dealer that receives Exchange Notes for your own account in exchange for Restricted Notes that you acquired as a result of market-making activities or any other trading activities, you will be required to acknowledge that you will deliver a prospectus in connection with any resale of such Exchange Notes.

USE OF PROCEEDS

Albemarle and Wodgina, respectively, will not receive any proceeds from the issuance of the Exchange Notes. In consideration for issuing the Exchange Notes contemplated by this prospectus, the issuers will receive Restricted Notes in a like principal amount. Any Restricted Notes that are properly tendered and exchanged pursuant to the exchange offers will be retired and cancelled.

16

THE EXCHANGE OFFERS

Purpose and Effect of the Exchange Offers

The issuers entered into Registration Rights Agreement with the initial purchasers of the Restricted Notes of the applicable series in which the issuers agreed, under certain circumstances to use their reasonable efforts to file with the SEC a registration statement relating to offers to exchange the Restricted Notes for Exchange Notes, cause the registration statement to become effective under the Securities Act and complete the exchange offers within 365 days after the original issue date of the Restricted Notes (the “Issue Date”). The Exchange Notes will have terms substantially identical to the terms of such Restricted Notes and related guarantees of such series of Restricted Notes, except that the transfer restrictions, registration rights and additional interest provisions relating to such notes will not apply. The 2022 Restricted Notes and 2029 Restricted Notes were issued on November 25, 2019.

For each Restricted Note surrendered to the issuers pursuant to the exchange offers, the holder who surrendered such Restricted Note will receive an Exchange Note having a principal amount equal to that of the surrendered Restricted Note. Interest on such Exchange Note will accrue (a) from the later of (i) the last interest payment date on which interest was paid on the Restricted Note surrendered in exchange therefor or (ii) if the Restricted Note is surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date or (b) if no interest has been paid on such Restricted Note, from the Issue Date of the Restricted Notes.

Under the Registration Rights Agreement, if the issuers fail to complete the exchange offers (other than in the event the issuers file a shelf registration statement) or the shelf registration statement, if required thereby, is not declared effective, in either case on or prior to 365 days after the Issue Date (a “Registration Default”), then additional interest will accrue on the principal amount of the applicable series of Restricted Notes that are “registrable securities” (such additional interest, the “Additional Interest”), from and including the date on which any such Registration Default shall occur to, but excluding, the date on which the Registration Default has been cured, in an amount equal to 0.25% per annum (which rate will be increased by an additional 0.25% per annum for each subsequent90-day period that such additional interest continues to accrue, provided that the rate at which such additional interest accrues may in no event exceed 1.00% per annum). Following the cure of all Registration Defaults, the accrual of Additional Interest will cease. A copy of the Registration Rights Agreement has been filed as an exhibit to the registration statement of which this prospectus is a part.

If you wish to exchange your outstanding Restricted Notes for Exchange Notes in the exchange offers, you will be required to make the following written representations:

Each broker-dealer that receives Exchange Notes for its own account in exchange for outstanding Restricted Notes, where the broker-dealer acquired the outstanding Restricted Notes as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

17

Resale of Exchange Notes

Based on interpretations by the SEC set forth inno-action letters issued to third parties, the issuers believe that you may resell or otherwise transfer Exchange Notes issued in the exchange offers without complying with the registration and prospectus delivery provisions of the Securities Act, if:

If you are our affiliate, or are engaging in, or intend to engage in, or have any arrangement or understanding with any person to participate in, a distribution of the Exchange Notes, or are not acquiring the Exchange Notes in the ordinary course of your business:

This prospectus may be used for an offer to resell, resale or other transfer of Exchange Notes only as specifically set forth in this prospectus. With regard to broker-dealers, only broker-dealers that acquired the Restricted Notes as a result of market-making activities or other trading activities may participate in the exchange offers. Each broker-dealer that receives Exchange Notes for its own account in exchange for Restricted Notes, where such Restricted Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes. Please read “Plan of Distribution” for more details regarding the transfer of Exchange Notes.

Terms of the Exchange Offers

On the terms and subject to the conditions set forth in this prospectus and in the accompanying letter of transmittal, the issuers will accept for exchange in the exchange offers any Restricted Notes that are validly tendered and not validly withdrawn prior to the expiration date. Restricted Notes may only be tendered in a minimum denomination of $2,000 and integral multiples of $1,000 thereafter, and any unexchanged portion of a Restricted Note must be in a principal amount of $2,000 or integral multiples of $1,000 thereafter. The issuers will issue Exchange Notes in principal amounts identical to the Restricted Notes surrendered in the exchange offers.

The form and terms of the Exchange Notes will be identical in all material respects to the form and terms of the Restricted Notes of the corresponding series except the Exchange Notes will be registered under the Securities Act, will not bear legends restricting their transfer and will not provide for any additional interest upon our failure to fulfill our obligations under the Registration Rights Agreement to complete the exchange offers, or file, and cause to be effective, a shelf registration statement, if required thereby, within the specified time period. The Exchange Notes will evidence the same debt as the Restricted Notes of the corresponding series. The Exchange Notes will be issued under and entitled to the benefits of the indenture that authorized the issuance of the Restricted Notes. For a description of the indenture, see “Description of the Exchange Notes.”

18

The exchange offers are not conditioned upon any minimum aggregate principal amount of Restricted Notes being tendered for exchange.

As of the date of this prospectus, $200 million aggregate principal amount of the Floating Rate Notes due 2022 and $300 million aggregate principal amount of the 3.450% Senior Notes due 2029 that were issued in a private offering on November 25, 2019 are outstanding and unregistered. This prospectus and the letter of transmittal are being sent to all registered holders of Restricted Notes. There will be no fixed record date for determining registered holders of Restricted Notes entitled to participate in the exchange offers. The issuers intend to conduct the exchange offers in accordance with the provisions of the Registration Rights Agreement, the applicable requirements of the Securities Act and the Exchange Act and the rules and regulations of the SEC. Restricted Notes that are not tendered for exchange in the exchange offers will remain outstanding and continue to accrue interest and will be entitled to the rights and benefits such holders have under the indenture relating to such holders’ series of Restricted Notes and the Registration Rights Agreement except, the issuers will not have any further obligation to you to provide for the registration of the Restricted Notes under the Registration Rights Agreement. The issuers will be deemed to have accepted for exchange properly tendered Restricted Notes when the issuers have given written notice of the acceptance to the exchange agent. The exchange agent will act as agent for the issuers for the purposes of receiving the Exchange Notes for the issuers and delivering Exchange Notes to holders. Subject to the terms of the Registration Rights Agreement, the issuers expressly reserve the right to amend or terminate the exchange offers and to refuse to accept the occurrence of any of the conditions specified below under “—Conditions to the Exchange Offers.”

If you tender your Restricted Notes in the exchange offers, you will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of Restricted Notes. The issuers will pay all charges and expenses, other than certain applicable taxes described below in connection with the exchange offers. It is important that you read “—Fees and Expenses” below for more details regarding fees and expenses incurred in the exchange offers.

Expiration Date; Extensions, Amendments

As used in this prospectus, the term “expiration date” means 11:59 p.m., New York City time, on July 23, 2020. However, if the issuers, in their sole discretion, extend the period of time for which the exchange offers are open, the term “expiration date” will mean the latest time and date to which the issuers shall have extended the expiration of such exchange offer.

To extend the period of time during which the exchange offers are open, the issuers will notify the exchange agent of any extension by written notice, followed by notification by press release or other public announcement to the registered holders of the Restricted Notes no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

The issuers expressly reserve the right, so long as applicable law allows:

19

The issuers will promptly follow any delay in acceptance, termination, extension or amendment by oral or written notice of the event to the exchange agent, followed promptly by oral or written notice to the registered holders. Should the issuers choose to delay, extend, amend or terminate the exchange offers, the issuers will have no obligation to publish, advertise or otherwise communicate this announcement, other than by making a timely release to a financial news service.

In the event the issuers terminate the exchange offers, all Restricted Notes previously tendered and not accepted for payment will be returned promptly to the tendering holders.

In the event that the exchange offers are withdrawn or otherwise not completed, Exchange Notes will not be given to holders of Restricted Notes who have validly tendered their Restricted Notes.

Acceptance of Restricted Notes for Exchange

In all cases, the issuers will promptly issue Exchange Notes for outstanding Restricted Notes that it has accepted for exchange under the exchange offers only after the exchange agent timely receives:

By tendering outstanding Restricted Notes pursuant to the exchange offers, you will represent to the issuers that, among other things:

In addition, each broker-dealer that is to receive Exchange Notes for its own account in exchange for outstanding Restricted Notes must represent that such outstanding Restricted Notes were acquired by that broker-dealer as a result of market-making activities or other trading activities and must acknowledge that it will deliver a prospectus that meets the requirements of the Securities Act in connection with any resale of the Exchange Notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. See “Plan of Distribution.”

The issuers will interpret the terms and conditions of the exchange offers, including the letter of transmittal and the instructions to the letter of transmittal, and will resolve all questions as to the validity, form, eligibility, including time of receipt, and acceptance of outstanding Restricted Notes tendered for exchange. Our determinations in this regard will be final and binding on all parties. The issuers reserves the absolute right to reject any and all tenders of any particular outstanding Restricted Notes not properly tendered or not to accept any

20

particular Restricted Notes if the acceptance might, in its or its counsel’s judgment, be unlawful. The issuers also reserve the absolute right to waive any defects or irregularities as to any particular outstanding Restricted Notes prior to the Expiration Date.

Unless waived, any defects or irregularities in connection with tenders of outstanding Restricted Notes for exchange must be cured within such reasonable period of time as the issuers determine. Neither of the issuers, the exchange agent or any other person will be under any duty to give notification of any defect or irregularity with respect to any tender of outstanding Restricted Notes for exchange, nor will any of them incur any liability for any failure to give notification. Any outstanding Restricted Notes received by the exchange agent that are not properly tendered and as to which the irregularities have not been cured or waived will be returned by the exchange agent to the tendering holder, unless otherwise provided in the letter of transmittal, promptly after the Expiration Date.

Procedures for Tendering Restricted Notes

To tender your outstanding Restricted Notes in the exchange offers, you must comply with either of the following:

In addition, either:

Your tender, if not withdrawn prior to the Expiration Date, constitutes an agreement between the issuers and you upon the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

If you wish to exchange your outstanding Restricted Notes for Exchange Notes in the exchange offers, you will be required to make the written representations as set forth in “—Purpose and Effect of the Exchange Offers.”

The method of delivery of outstanding Restricted Notes, letters of transmittal and all other required documents to the exchange agent is at your election and risk. The issuers recommend that instead of delivery by mail, you use an overnight or hand delivery service, properly insured. In all cases, you should allow sufficient time to assure timely delivery to the exchange agent before the Expiration Date. You should not send letters of transmittal or certificates representing outstanding Restricted Notes to the issuers. You may request that your broker, dealer, commercial bank, trust company or nominee effect the above transactions for you.

If you are a beneficial owner whose outstanding Restricted Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your outstanding Restricted Notes, you should promptly contact your registered holder and instruct the registered holder to tender on your behalf.

Signatures on the letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the Financial Industry Regulatory Authority, Inc., a commercial bank or trust company having an office or correspondent in the United States or another “eligible guarantor institution” within the meaning of Rule17A(d)-15 under the Exchange Act unless the outstanding Restricted Notes surrendered for exchange are tendered:

21

If the letter of transmittal is signed by a person other than the registered holder of any Restricted Notes listed on the outstanding Restricted Notes, such outstanding Restricted Notes must be endorsed or accompanied by a properly completed bond power. The bond power must be signed by the registered holder as the registered holder’s name appears on the outstanding Restricted Notes, and an eligible guarantor institution must guarantee the signature on the bond power.

If the letter of transmittal, any certificates representing outstanding Restricted Notes or bond powers are signed by trustees, executors, administrators, guardians,attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, those persons should also indicate when signing and, unless waived by the issuers, they should also submit evidence satisfactory to the issuers of their authority to so act.

The exchange agent and DTC have confirmed that any financial institution that is a participant in DTC’s system may use DTC’s Automated Tender Offer Program to tender Restricted Notes. Participants in the program may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, electronically transmit their acceptance of the exchange by causing DTC to transfer the Restricted Notes to the exchange agent in accordance with DTC’s Automated Tender Offer Program procedures for transfer. DTC will then send an agent’s message to the exchange agent. The term “agent’s message” means a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, which states that:

Book-Entry Transfer

The exchange agent will seek to establish a new account or utilize an existing account with respect to the Restricted Notes at DTC promptly after the date of this prospectus. Any financial institution that is a participant in the DTC system and whose name appears on a security position listing as the owner of the Restricted Notes may make book-entry delivery of Restricted Notes by causing DTC to transfer such Restricted Notes into the exchange agent’s account. The confirmation of a book-entry transfer of Restricted Notes into the exchange agent’s account at DTC is referred to in this prospectus as a “book-entry confirmation.” Delivery of documents to DTC in accordance with DTC’s procedures does not constitute delivery to the exchange agent.

Other Matters

Exchange Notes will be issued in exchange for Restricted Notes accepted for exchange only after timely receipt by the exchange agent of:

22

The issuers will determine, in the sole discretion of the issuers, all questions as to the form of all documents, validity, eligibility, including time of receipt, and acceptance of all tenders of Restricted Notes. There will be no guaranteed delivery procedures for the exchange offers. Our determination will be final and binding on all parties. Alternative, conditional or contingent tenders of Restricted Notes will not be considered valid.The issuers reserve the absolute right to reject any or all tenders of Restricted Notes that are not in proper form or the acceptance of which, in our opinion, would be unlawful. The issuers also reserve the right to waive any defects, irregularities or conditions of tender as to particular Restricted Notes.

Our interpretation of the terms and conditions of the exchange offers, including the instructions in the accompanying letter of transmittal, will be final and binding.

Any defect or irregularity in connection with tenders of Restricted Notes must be cured within the time the issuers determine, unless waived by the issuers. The issuers will not consider the tender of Restricted Notes to have been validly made until all defects and irregularities have been waived by the issuers or cured. Neither of the issuers, the exchange agent or any other person will be under any duty to give notice of any defects or irregularities in tenders of Restricted Notes, or will incur any liability to holders for failure to give any such notice.

Withdrawal of Tenders

Except as otherwise provided in this prospectus, you may withdraw your tender of Restricted Notes at any time prior to the Expiration Date.

For a withdrawal to be effective:

Any notice of withdrawal must:

If Restricted Notes have been tendered pursuant to the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Restricted Notes and otherwise comply with the procedures of DTC.

The issuers will determine in the sole discretion of the issuers all questions as to validity, form, eligibility and time of receipt of any withdrawal notices. Our determination will be final and binding on all parties. The issuers will deem any Restricted Notes so withdrawn not to have been validly tendered for exchange for purposes of the exchange offers.

Any Restricted Notes that have been tendered for exchange but that are not exchanged for any reason will be returned to their holder without cost to the holder or, in the case of Restricted Notes tendered by book-entry transfer into the exchange agent’s account at DTC according to the procedures described above, such Restricted Notes will be credited to an account maintained with DTC for the Restricted Notes. This return or crediting will take place promptly after withdrawal, rejection of tender or termination of the exchange offers. You may retender properly withdrawn Restricted Notes by following one of the procedures described under “—Procedures for Tendering Restricted Notes” at any time on or prior to the Expiration Date.

23

Conditions to the Exchange Offer

Despite any other term of the exchange offers, the issuers will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any outstanding Restricted Notes and it may terminate or amend the exchange offers as provided in this prospectus prior to the Expiration Date if in its reasonable judgment:

The issuers expressly reserves the right at any time or at various times to extend the period of time during which the exchange offers is open. Consequently, the issuers may delay acceptance of any Restricted Notes by giving oral or written notice of such extension to their holders. The issuers will return any outstanding Restricted Notes that it does not accept for exchange for any reason without expense to their tendering holder promptly after the expiration or termination of the exchange offers.

The issuers expressly reserves the right to amend or terminate the exchange offers and to reject for exchange any outstanding Restricted Notes not previously accepted for exchange, upon the occurrence of any of the conditions to the exchange offers specified above. The issuers will give oral or written notice of any extension, amendment,non-acceptance or termination of the exchange offers to the holders of the outstanding Restricted Notes as promptly as practicable. In the case of any extension of the exchange offers, such notice will be issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

These conditions are for our sole benefit, and the issuers may assert them regardless of the circumstances that may give rise to them or waive them in whole or in part at any or at various times prior to the Expiration Date in the sole discretion of the issuers. If the issuers fails at any time to exercise any of the foregoing rights, this failure will not constitute a waiver of such right. Each such right will be deemed an ongoing right that it may assert at any time or at various times prior to the Expiration Date.

In addition, the issuers will not accept for exchange any outstanding Restricted Notes tendered, and will not issue Exchange Notes in exchange for any such outstanding Restricted Notes, if at such time any stop order is threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture governing the Exchange Notes under the Trust Indenture Act of 1939, as amended.

Consequences of Failing to Exchange

If you do not exchange your Restricted Notes for Exchange Notes in the exchange offers, you will remain subject to the restrictions on transfer of the Restricted Notes:

In general, you may not offer or sell the Restricted Notes unless they are registered under the Securities Act, or if the offer or sale is exempt from registration under the Securities Act and applicable state securities laws. Upon completion of the exchange offers, the issuers are under no obligation to, and do not intend to, register resales of the outstanding Restricted Notes under the Securities Act.

24

Accounting Treatment

The Exchange Notes will be recorded at the same carrying value as the Restricted Notes, as reflected in our accounting records on the date of the exchange. Accordingly, the issuers will not recognize any gain or loss for accounting purposes upon the consummation of the exchange offers. The expenses of the exchange offers and the remaining unamortized expenses related to the issuance of the Restricted Notes will be amortized over the term of the Exchange Notes.

DESCRIPTION OF THE EXCHANGE NOTES

The following description is a summary of the terms of the Exchange Notes being offered. The descriptions in this prospectus contain descriptions of certain terms of the Exchange Notes, the 2029 Exchange Note Guarantee and the indenture but do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the indenture including the definitions of specified terms used in the indenture. When we refer to “Albemarle” in this section, we refer only to Albemarle Corporation and not to its subsidiaries and when we refer to “Wodgina” in this section, we refer only to Albemarle Wodgina Pty Ltd and not to its subsidiaries. As used in this section, “issuer” refers to Albemarle when used with respect to the 2022 Exchange Notes and Wodgina when used with respect to the 2029 Exchange Notes, as applicable, and “guarantor” refers to Albemarle when used with respect to its guarantee of the 2029 Exchange Notes.

General

The Exchange Notes will be issued under the indenture dated as of January 20, 2005, between Albemarle and U.S. Bank National Association, as successor to The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York), as trustee, as supplemented by a fifth supplemental indenture (as so supplemented, the “indenture”), dated November 25, 2019, among Albemarle, as issuer of the 2022 Restricted Notes and as guarantor of the 2029 Restricted Notes, Wodgina, as issuer of the 2029 Exchange Notes, and U.S. Bank National Association, as trustee (the “trustee”). You should also refer to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), certain terms of which are made a part of the indenture by reference. With respect to the Exchange Notes of each series, the “date of the indenture” as used in this “Description of the Exchange Notes” means November 25, 2019.

The indenture does not limit Albemarle’s or Wodgina’s ability or the ability of their respective subsidiaries to incur additional indebtedness. As of March 31, 2020, Albemarle had consolidated total debt of approximately $3.14 billion, of which $1.46 billion) is indebtedness of Albemarle’s subsidiaries (or $1.10 billion) excluding Wodgina).

2022 Exchange Notes

The 2022 Exchange Notes will be initially issued in an aggregate principal amount of $200,000,000 and will mature on November 15, 2022 (the “Floating Rate Maturity Date”). The 2022 Exchange Notes will be direct unsecured obligations of Albemarle. The 2022 Exchange Notes are not guaranteed.

Interest

The 2022 Exchange Notes will bear interest (a) from the later of (i) the last interest payment date on which interest was paid on the 2022 Restricted Notes or (ii) if the 2022 Restricted Notes are surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date , at a floating rate determined in the manner provided below, payable quarterly on February 15, May 15, August 15 and November 15 of each year (each such day, a “Floating Rate Interest Payment Date”), to the persons in whose names the 2022 Exchange Notes are registered at the close of business on the immediately preceding February 1, May 1, August 1, and November 1, respectively (whether or not a Business Day). The per annum interest rate on the 2022 Exchange Notes (the “Floating Interest Rate”) in effect for each day of an Interest Period (as defined below) will be equal to the Three-Month LIBOR Rate plus 105 basis points (1.05%). The Floating Interest Rate for each Interest Period for the 2022 Exchange Notes will be reset on February 15, May 15, August 15 and November 15 of each year, commencing August 15, 2020 (each such date, an “Interest Reset Date”), until the principal on the 2022 Exchange Notes is paid or made available for payment. The applicable interest rate will be determined two London Business Days prior to each Interest Reset Date (each such date, an “Interest Determination Date”). If any Interest Reset Date and Floating Rate Interest Payment Date (other than the maturity date) for the 2022 Exchange Notes would otherwise be a day that is not a Business Day, such Interest Reset Date and Floating Rate Interest Payment Date will be the next succeeding Business Day, unless the next succeeding Business Day is in the next succeeding calendar month, in which case such Interest Reset Date and Floating Rate Interest Payment Date will be the immediately preceding Business Day (in each case, resulting in a corresponding adjustment to the number of days in the applicable Interest Period). If the maturity date of the 2022 Exchange Notes falls on a day that is not a Business Day, then the related payment of principal and interest will be made on the next day that is a Business Day with the same effect as if made on the date that the payment was first due, and no interest will accrue on the amount so payable for the period from the maturity date.

27

The amount of interest for each day that the 2022 Exchange Notes are outstanding (the “Daily Interest Amount”) will be calculated by dividing the Floating Interest Rate in effect for such day by 360 and multiplying the result by the principal amount of 2022 Exchange Notes. The amount of interest to be paid on the 2022 Exchange Notes for any Interest Period will be calculated by adding the Daily Interest Amounts for each day in such Interest Period.

All percentages resulting from any calculation on the 2022 Exchange Notes will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with fiveone-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) will be rounded upward to 9.87655% (or .0987655)), and all amounts used in or resulting from the calculation on the 2022 Exchange Notes will be rounded to the nearest cent (withone-half cent being rounded upward).

The Floating Interest Rate on the 2022 Exchange Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. In no event will the Floating Interest Rate be less than 0.0%.

The Floating Interest Rate and amount of interest to be paid on the 2022 Exchange Notes for each Interest Period will be determined by the calculation agent. All calculations made by the calculation agent shall in the absence of manifest error be conclusive for all purposes and binding on Albemarle, the trustee and the holders of the 2022 Exchange Notes. So long as a Benchmark is required to be determined with respect to the 2022 Exchange Notes, there will at all times be a calculation agent. Initially, U.S. Bank National Association shall serve as calculation agent, provided, however, that U.S. Bank National Association, in its role as calculation agent, trustee or in any other capacity, will not serve as our Designee (as defined below) for purposes of paragraph (b)(2) of the definition of “Three-Month LIBOR Rate”, or in making the determinations described under “Effect of Benchmark Transition Event” below.” U.S. Bank National Association, in its role as calculation agent, trustee or in any other capacity, shall not have any (i) responsibility or liability for the selection, adoption or determination of an alternative or replacement reference rate (including a Benchmark Replacement Adjustment or any Benchmark Replacement Conforming Changes) as a successor or replacement benchmark (including whether any such rate is the appropriate Benchmark Replacement or whether any other conditions to the designation of such rate or any of the determinations described in “Effect of Benchmark Transition Event” below have been satisfied) and shall be entitled to rely upon any determination or designation of such a rate (and any Benchmark Replacement Adjustment or Benchmark Replacement Conforming Changes, or other modifier) by Albemarle or its Designee, or (ii) liability for any failure or delay by Albemarle or its Designee in performing its or their respective duties under the indenture or other transaction documents as a result of the unavailability of LIBOR, or any other Benchmark Replacement described herein or the failure of a Benchmark Replacement to be adopted. The calculation agent may at any time resign by giving written notice to Albemarle of such intention on its part, specifying the date on which such resignation shall become effective;provided that such notice shall be given not less than thirty (30) days prior to stated effective date unless we otherwise agree. The calculation agent may be removed by Albemarle by giving notice in writing specifying such removal and the date when it shall become effective. Upon receipt of such notice of resignation or the giving of such notice of removal, Albemarle shall promptly appoint a successor calculation agent (which may be Albemarle, an affiliate or another person which is a bank, trust company, investment banking firm, or other financial institution), which appointment shall take effect prior to the effective date of such resignation or removal. For the avoidance of doubt, the effectiveness of such resignation or removal shall not be conditional upon or subject to the effectiveness of such appointment of a successor.

The 2022 Exchange Notes will not be subject to redemption at Albemarle’s option at any time prior to November 15, 2020 (two years prior to the maturity date, the “2022 Exchange Notes Par Call Date”).

At any time, or from time to time, on or after the 2022 Exchange Notes Par Call Date, the 2022 Exchange Notes will be redeemable as a whole or in part, at Albemarle’s option, at a redemption price equal to 100% of the principal amount of the Exchange Notes to be redeemed plus accrued and unpaid interest on the Exchange Notes to be redeemed to, but excluding, the date of redemption.

2029 Exchange Notes

The 2029 Exchange Notes will be initially issued in an aggregate principal amount of $300,000,000 and will mature on November 15, 2029. The 2029 Exchange Notes will be direct unsecured obligations of Wodgina, and on the issue date will be fully and unconditionally guaranteed on an unsubordinated unsecured basis by Albemarle.

32

Interest

The 2029 Exchange Notes will bear interest at the applicable rate per annum shown on the cover of this prospectus from (a) from the later of (i) the last interest payment date on which interest was paid on the 2029 Restricted Notes or (ii) if the 2029 Restricted Notes are surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date, payable semi-annually on May 15 and November 15, to the persons in whose names the Exchange Notes are registered at the close of business on the next preceding May 1 or November 1, respectively. Interest on the 2029 Exchange Notes will be computed on the basis of a360-day year of twelve30-day months.

Guarantee

Once released in accordance with its terms, the 2029 Exchange Note Guarantee will not be required to be reinstated for any reason. At Wodgina’s written instruction, the trustee will execute and deliver any documents, instructions or instruments evidencing any release of the 2029 Exchange Note Guarantee.

The indenture will provide that the obligations of Albemarle under its 2029 Exchange Note Guarantee will be limited to the maximum amount that, after giving effect to all other contingent and fixed liabilities of Albemarle, would cause the 2029 Exchange Note Guarantee of Albemarle not to constitute a fraudulent conveyance or fraudulent transfer under any applicable law; provided, however, there is some doubt as to whether this limitation will be effective to prevent the 2029 Exchange Note Guarantee from constituting a fraudulent conveyance.

“Reference Treasury Dealer” means each of (1) BofA Securities, Inc. and J.P. Morgan Securities LLC or their respective affiliates which are Primary Treasury Dealers, and their respective successors and (2) two other Primary Treasury Dealers appointed by us; provided, however, that if any of the foregoing or their affiliates shall cease to be a Primary Treasury Dealer, Wodgina shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 p.m. New York time on the third business day preceding such redemption date.

If a Payor is so required to withhold or deduct any amount for or on account of taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction from any payment made under or with respect to the 2029 Exchange Notes or the 2029 Exchange Note Guarantee, as applicable, such Payor will be required to pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by any holder (including Additional Amounts) after such withholding or deduction will not be less than the amount the holder or beneficial owner would have received if such taxes had not been withheld or deducted; provided, however, that the foregoing obligation to pay Additional Amounts does not apply to:

34

(a) any taxes that would not have been (or would not be required to be) so imposed, withheld, deducted or levied but for the existence of any present or former connection between the relevant holder or beneficial owner (or between a fiduciary, settlor, beneficiary, partner, member or shareholder of, or possessor of power over, the relevant holder or beneficial owner, if the relevant holder or beneficial owner is an estate, nominee, trust, partnership, company or corporation) and the Relevant Taxing Jurisdiction, including, without limitation, such holder or beneficial owner being or having been a citizen, domiciliary, national resident thereof, or being or having been present or engaged in a trade or business therein or having or having had a permanent establishment therein (other than any connection arising solely from the acquisition or holding of any 2029 Exchange Notes, the receipt of any payments in respect of such Exchange Notes or the 2029 Exchange Note Guarantee or the exercise or enforcement of rights under the 2029 Exchange Note Guarantee);

(b) any estate, inheritance, gift, sales, transfer, personal property or similar tax or assessment;

(e) any taxes imposed or withheld on or with respect to a payment which could have been made without deduction or withholding if the beneficiary of the payment had presented the 2029 Exchange Notes for payment (where presentation is required) within 30 days after the date on which such payment or such 2029 Exchange Notes became due and payable or the date on which payment thereof is duly provided for, whichever is later (except to the extent that the holder or beneficial owner would have been entitled to Additional Amounts had the 2029 Exchange Notes been presented on any day during the30-day period);

(f) any taxes imposed on or with respect to any payment made under or with respect to such 2029 Exchange Notes or the 2029 Exchange Note Guarantee to any holder who is a fiduciary or partnership or any Person other than the sole beneficial owner of such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the sole beneficial owner of such 2029 Exchange Notes;

(g) any taxes payable under Sections 1471-1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), as of the issue date of the 2029 Exchange Notes (or any amended or successor version), any regulations or official interpretations thereof, any intergovernmental agreement entered into in connection therewith, or any law or regulation adopted pursuant to an intergovernmental agreement between anon-U.S. jurisdiction and the United States with respect to the foregoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code; or

(h) any taxes imposed or levied by reason of any combination of clauses (a) through (g) above.

The Payor will pay any present or future stamp, issue, registration, excise, property, court or documentary taxes, or similar taxes, charges or levies (referred to in this paragraph as “stamp taxes”) and interest, penalties and other reasonable expenses related thereto that arise in or are levied by any Relevant Taxing Jurisdiction on the execution, issuance, delivery, enforcement or registration of the 2029 Exchange Notes, the indenture, the 2029 Exchange Note Guarantee or any other document or instrument in relation thereto (other than on a transfer or assignment of the 2029 Exchange Notes after this offering).

The Payor will make or cause to be made any withholding or deduction required in respect of taxes, and remit the full amount deducted or withheld to the Relevant Taxing Jurisdiction, in accordance with applicable law. Upon request, the Payor will use reasonable efforts to provide, within a reasonable time after the date the payment of any such taxes so deducted or withheld is made, the trustee with official receipts or other documentation evidencing the payment of the taxes so deducted or withheld.

35

If any Payor will be obligated to pay Additional Amounts under or with respect to any payment made on the 2029 Exchange Notes, the Payor will deliver to the paying agent with a copy to the trustee on a date that is at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 45th day prior to that payment date, in which case the Payor shall notify the paying agent and the trustee promptly thereafter) a certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable and such other information reasonably necessary to enable the paying agent to pay Additional Amounts to holders or beneficial owners on the relevant payment date.

Whenever in the indenture or this “Description of the Exchange Notes” there is mentioned, in any context:

(a) the payment of principal;

(b) the payment of interest; or

(c) any other amount payable on or with respect to any of the Exchange Notes,

such reference will be deemed to include payment of Additional Amounts as described under this heading “—Additional Amounts,” to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The obligations described under this heading, “—Additional Amounts,” will survive any termination, defeasance or discharge of the indenture or the 2029 Exchange Note Guarantee and will applymutatis mutandis to any jurisdiction in which any successor Person to the Payor is incorporated, organized or otherwise resident for tax purposes or any political subdivision or taxing authority or agency thereof or therein.

Optional Redemption for Changes in Withholding Taxes

Wodgina is entitled to redeem the 2029 Exchange Notes, at its option, at any time in whole but not in part, upon not less than 15 nor more than 60 days’ notice to the holders, at a redemption price equal to 100% of the outstanding principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event the Payor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the notes, any Additional Amounts as a result of:

(a) a change in, or an amendment to, the laws (including any regulations or rulings promulgated thereunder) or treaties of any Relevant Taxing Jurisdiction; or

(b) any change in, amendment to, or introduction of any official published position regarding the application, administration or interpretation of such laws (including any regulations or rulings promulgated thereunder and including the decision of any court, governmental agency or tribunal), which change, amendment or introduction is publicly announced or becomes effective on or after the date of the indenture and the Payor cannot avoid such obligation by taking reasonable measures available to it (including making payment through a paying agent located in another jurisdiction), provided that such Payor will not be required to take any measures that would result in the imposition on it of any material legal or regulatory burden or the incurrence by it of any material additional costs, or would otherwise result in any material adverse consequences. The foregoing provisions will apply mutatis mutandis to the laws and official positions of any jurisdiction in which any successor permitted under “—Certain Covenants—Consolidation, Merger and Sale of Assets” is incorporated, organized or otherwise resident for tax purposes or any political subdivision or taxing authority or agency thereof or therein.

Prior to the giving of any notice of redemption described in the preceding paragraph, Wodgina will deliver to the trustee an officer’s certificate to the effect that the Payor cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. Wodgina will also deliver to the trustee an opinion of counsel of recognized standing to the effect that the Payor would be obligated to pay Additional Amounts as a result of a change, amendment, or introduction described above. Absent manifest error, the trustee will accept such opinion as sufficient evidence of the Payor’s obligations, to pay such Additional Amounts, and it will be conclusive and binding on the holders.

36

The Exchange Notes

Each series of Exchange Notes will be issued only in fully registered form in minimum denominations of $2,000 and multiples of $1,000 in excess thereof.

The issuer of each series of Exchange Notes may from time to time without notice to, or the consent of, the holders of such series of Exchange Notes, create and issue additional Exchange Notes of such series under the indenture, equal in rank to the Exchange Notes of such series in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the new Exchange Notes, or except under certain circumstances for the first payment of interest following the issue date of the new Exchange Notes) so that the new Exchange Notes may be consolidated and form a single series with the Exchange Notes and have the same terms as to status, redemption and otherwise as the Exchange Notes of such series issued under this prospectus.

Interest

Interest on the Exchange Notes will be paid by check mailed on an interest payment date other than a maturity date to the persons entitled thereto to the addresses of such holders as they appear in the security register or, at the issuer’s option, by wire transfer to a bank account maintained by the holder. The principal of, premium, if any, and interest on the Exchange Notes, together with interest accrued and unpaid thereon, due on the applicable maturity date will be paid in immediately available funds upon surrender of such Exchange Notes at the corporate trust office of the trustee in The City of New York, or, at the issuer’s option, by wire transfer of immediately available funds to an account with a bank designated at least 15 calendar days prior to the maturity date by the applicable registered holder, provided the particular bank has appropriate facilities to receive these payments and the particular note is presented and surrendered at the office or agency maintained by us for this purpose in the Borough of Manhattan, The City of New York, in time for the trustee to make these payments in accordance with its normal procedures. Notwithstanding the foregoing, if Exchange Notes are held in the form of global securities, all payments will be made in accordance with the applicable procedures of the depositary.

Exchange and Transfer

For each series of Exchange Notes, a global security will be issued in denominations equal to the aggregate principal amount of outstanding Exchange Notes of such series represented by that global security.

You may have your Exchange Notes broken into more notes of smaller denominations or combined into fewer notes of larger denominations, as long as the total principal amount is not changed. This is called an exchange.

You may exchange or transfer Exchange Notes at the office of the security registrar. The security registrar acts as the issuers’ agent for registering notes in the names of holders and transferring notes. The issuers may change this appointment to another entity or perform the service ourselves. The entity performing the role of maintaining the list of registered holders is called the security registrar and the initial security registrar is the trustee. It will also register transfers of the notes. The security register for the notes will be maintained at an office or agency of the trustee in the United States.

You will not be required to pay a service charge to transfer or exchange notes, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

The issuers may cancel the designation of any particular transfer agent. The issuers may also approve a change in the office through which any transfer agent acts.

Payments on the Notes

Payments of the principal and premium, if any, in respect of Exchange Notes of a series that are not global securities will be made upon the surrender of the Exchange Notes of such series at the office or agency of the issuers maintained for that purpose in the City of New York designated from time to time by the trustee and payments of interest will be made by check mailed to holders of the Exchange Notes of such series at their addresses set forth in the security register; provided, however, that payments of interest will be made by wire transfer if a holder of at least $1.0 million in principal amount of Exchange Notes has given wire transfer instructions to the trustee at least five business days prior to the applicable interest payment date. All payments of Exchange Notes of a series that are represented by global securities will be made by the transfer of immediately available funds to the nominee of the depositary for the Exchange Notes of such series.

37

Optional Redemption

Notice of redemption will be sent at least 15 but not more than 60 days before the redemption date to each holder of record of the Exchange Notes to be redeemed at its registered address. If less than all of the Exchange Notes are to be redeemed at any time, the trustee will select Exchange Notes to be redeemed on a pro rata basis, by lot, or by any other method the trustee deems fair and appropriate (or in accordance with applicable DTC procedures). The notice of redemption for the Exchange Notes will state, among other things, the amount of the Exchange Notes to be redeemed, the redemption date, the manner in which the redemption price will be calculated and the place or places that payment will be made upon presentation and surrender of Exchange Notes to be redeemed.

Unless the applicable issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Exchange Notes or portions thereof called for redemption.

The applicable issuer will pay interest to a person other than the holder of record on the record date if such issuer elects to redeem the Exchange Notes of a series on a date that is after a record date but on or prior to the corresponding interest payment date. In this instance, such issuer will pay accrued interest on the Exchange Notes being redeemed to, but not including, the redemption date to the same person to whom such issuer will pay the principal of those Exchange Notes.

Certain Covenants

General

The indenture contains certain covenants for the benefit of the holders of the Exchange Notes of each series, including, among other things, a covenant to maintain each issuer’s corporate existence. In addition, the indenture contains the covenants described in the two succeeding subsections. Capitalized terms used in the following summary have the meanings specified in the indenture, unless otherwise defined below.

This covenant has exceptions, which permit:

38

Notwithstanding the foregoing, Albemarle and any one or more of the Restricted Subsidiaries may issue, assume or guarantee Indebtedness secured by a Lien that would otherwise be subject to the foregoing restrictions if at the time of incurrence (the “Incurrence Time”), the amount equal to the sum of:

does not exceed 15% of Albemarle’s Consolidated Net Tangible Assets (as defined below).

including any extensions. The present value of the obligation of the lessee is discounted at the rate of interest implicit in the terms of the lease involved in the Sale and Leaseback Transaction, as determined in good faith by Albemarle. Net rental payments exclude any amounts required to be paid by the lessee, whether or not designated as rent or additional rent, on account of maintenance and repairs, services, insurance, taxes, assessments, water rates or similar charges or any amounts required to be paid by the lessee, subject to monetary inflation or the amount of sales, maintenance and repairs, insurance, taxes, assessments, water rates or similar charges.

“Consolidated Net Tangible Assets” means the aggregate amount of assets after deducting the following:

“Indebtedness” means, with respect to any Person on any date of determination, without duplication:

provided, however, that Indebtedness shall not include any indebtedness of a subsidiary to Albemarle or another subsidiary.

“Lien” means any mortgage, lien, pledge, charge of any kind (including any conditional sale or other title retention agreement or lease in the nature thereof), security interest or other encumbrance.

“Principal Property” means all real and tangible personal property owned or leased by Albemarle or any Restricted Subsidiary constituting a part of any manufacturing or processing plant or warehouse located within the United States, exclusive of (1) motor vehicles and other rolling stock, (2) office furnishings and equipment, and information and electronic data processing equipment, (3) any property financed through the issuance oftax-exempt industrial development bonds, (4) any real property held for development or sale, or (5) any property which in the opinion of Albemarle’s board of directors as evidenced by a resolution of the board of directors is not of material importance to the total business conducted by Albemarle and its Restricted Subsidiaries as an entirety.

40

“Restricted Subsidiary” means any of Albemarle’s subsidiaries (a) substantially all of whose property is located within the United States and (b) which owns a Principal Property or in which Albemarle’s investment exceeds 1% of the aggregate amount of assets included on Albemarle’s consolidated balance sheet as of the end of the last fiscal quarter for which financial information is available.

“Sale and Leaseback Transaction” means any arrangement involving any bank, insurance company, or other lender or investor (in each case that is not Albemarle or an affiliate of Albemarle) or to which any such lender or investor is a party that provides for the lease by Albemarle or one of its Restricted Subsidiaries for a period, including renewals, in excess of three years of any Principal Property which has been or is to be sold or transferred by Albemarle or any Restricted Subsidiary to the lender or investor or to any Person to whom funds have been or are to be advanced by such lender or investor on the security of the Principal Property.

Restrictions on Sale and Leaseback Transactions

Albemarle has agreed not to, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction, unless:

Notwithstanding the foregoing, Albemarle and its Restricted Subsidiaries, or any of them, may enter into a Sale and Leaseback Transaction that would otherwise be prohibited as set forth above, if either:

does not at the time exceed 15% of Albemarle’s Consolidated Net Tangible Assets.

“Funded Debt” means: (a) all Indebtedness maturing one year or more from the date of its creation, (b) all Indebtedness directly or indirectly renewable or extendable, at the option of the debtor, by its terms or by the terms of the instrument or agreement relating thereto, to a date one year or more from the date of its creation, and (c) all Indebtedness under a revolving credit or similar agreement obligating the lender or lenders to extend credit over a period of one year or more.

Except for the limitations on Liens and other encumbrances and Sale and Leaseback Transactions described above, each of which may not apply to subordinated debt securities, the indenture and the Exchange Notes do not contain any covenants or other provisions designed to afford holders of the Exchange Notes protection in the event of a highly leveraged transaction involving Albemarle.

41

Consolidation, Merger and Sale of Assets

The issuers are generally permitted to consolidate or merge with another company. The issuers are also permitted to sell or lease all or substantially all of their properties and assets to another company. However, an issuer may not take any of these actions unless:

For the purposes of this provision, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more subsidiaries of an issuer, which properties and assets, if held by such issuer instead of such subsidiaries, would constitute all or substantially all of the properties and assets of such issuer on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of such issuer.

The indenture’s provisions regarding our consolidation, merger and sale or lease of assets, as described above, include a phrase relating to the conveyance, transfer or lease of “all or substantially all” of our properties and assets. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the applicability of the foregoing provisions in the case of a sale of such assets or properties may be uncertain.

Offer to Repurchase Upon Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event with respect to any series of the Exchange Notes (unless the applicable issuer has exercised its right to redeem the Exchange Notes of such series by giving irrevocable notice to the trustee in accordance with the indenture), each holder of Exchange Notes of such series will have the right to require the issuer of such series of Exchange Notes to purchase all or a portion of such holder’s Exchange Notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, up to but not including the date of purchase (the “Change of Control Payment”).

Unless the applicable issuer has exercised its right to redeem the Exchange Notes of such series, within 30 days following the date upon which the Change of Control Triggering Event occurs with respect to a series of Exchange Notes or, at the option of the issuer of the Exchange Notes of such series, prior to any Change of Control but after the public announcement of the pending Change of Control, the applicable issuer will be required to send a notice to each holder of Exchange Notes of the applicable series to their addresses as set forth in the register, with a copy to the trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent, other than as may be required by law (the “Change of Control Payment Date”). The notice, if sent prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, each issuer will, to the extent lawful:

42

Neither issuer will be required to make a Change of Control Offer with respect to the Exchange Notes of the applicable series if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by such issuer and such third party purchases all the Exchange Notes of the applicable series properly tendered and not withdrawn under its offer. In addition, an issuer will not repurchase any Exchange Notes of the applicable series if there has occurred and is continuing on the Change of Control Payment Date an event of default under the indenture with respect to the Exchange Notes of such series, other than a default in the payment of the Change of Control Payment on the Change of Control Payment Date with respect to the Exchange Notes of such series.

The issuers must comply in all material respects with the requirements of Rule14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Exchange Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Exchange Notes, the issuers will be required to comply with those securities laws and regulations and will not be deemed to have breached the issuers’ respective obligations under the Change of Control Offer provisions of the Exchange Notes by virtue of any such conflict.

For purposes of the foregoing discussion of a Change of Control Offer, the following definitions are applicable:

“Change of Control” means the occurrence of any of the following after the date of issuance of the Exchange Notes:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of Albemarle’s assets and the assets of its subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) other than to Albemarle or one of its subsidiaries;

(2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than Albemarle or one of its subsidiaries) becomes the “beneficial owner” (as defined in Rules13d-3 and13d-5 under the Exchange Act), directly or indirectly, of Albemarle’s Voting Stock representing a majority of the voting power of Albemarle’s outstanding Voting Stock;

(3) Albemarle consolidates with, or merge with or into, any Person, or any Person consolidates with, or merges with or into, Albemarle, in any such event pursuant to a transaction in which any of Albemarle’s outstanding Voting Stock or Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where Albemarle’s Voting Stock outstanding immediately prior to such transaction constitutes, or is converted into or exchanged for, Voting Stock representing a majority of the voting power of the Voting Stock of the surviving Person immediately after giving effect to such transaction; or

(4) the adoption by Albemarle’s shareholders of a plan relating to its liquidation or dissolution.

Notwithstanding the foregoing, a transaction (or series of related transactions) will not be deemed to involve a Change of Control under clause (2) above if (i) Albemarle becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of Albemarle’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (as that term is used in Section 13(d)(3) of the Exchange Act) (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

“Change of Control Triggering Event” means, with respect to a series of Exchange Notes, (i) the rating of such series of Exchange Notes is lowered by each of the Rating Agencies on any date during the period (the “Trigger Period”) commencing on the earlier of (a) the occurrence of a Change of Control and (b) the first public announcement by Albemarle of any Change of Control (or pending Change of Control), and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following

43

consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change), and (ii) such series of Exchange Notes are rated below Investment Grade by each of the Rating Agencies on any day during the Trigger Period; provided that a Change of Control Triggering Event will not be deemed to have occurred in respect of a particular Change of Control if each Rating Agency making the reduction in rating does not publicly announce or confirm or inform the trustee at Albemarle’s or its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the Change of Control.

Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s) and a rating ofBBB- or better by S&P (or its equivalent under any successor rating category of S&P), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by Albemarle under the circumstances permitting Albemarle to select a replacement rating agency and in the manner for selecting a replacement rating agency, in each case as set forth in the definition of “Rating Agency.”

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Person” means any individual, corporation, partnership, limited liability company, business trust, association, joint-stock company, joint venture, trust, incorporated or unincorporated organization or government or any agency or political subdivision thereof.

“Rating Agency” means each of Moody’s and S&P; provided, that if either Moody’s or S&P ceases to provide rating services to issuers or investors, Albemarle may appoint another “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act as a replacement for such Rating Agency; provided that Albemarle shall give notice of such appointment to the trustee.

“S&P” means Standard & Poor’s Financial Services LLC, a division of S&P Global Inc., and its successors.

“Voting Stock” of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of Albemarle’s assets and the assets of its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the applicability of the requirement that the applicable issuer offer to repurchase the Exchange Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of Albemarle’s assets and the assets of its subsidiaries taken as a whole to another “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) may be uncertain.

Sinking Fund

There is no provision for a sinking fund applicable to the Exchange Notes.

Events of Default

The term “event of default” means, with respect to the Exchange Notes of a series, any of the following:

44

If an event of default described in clause (a), (b), (c) or, after notice in accordance with (d), above has occurred and is continuing, holders of 25% in aggregate principal amount of Exchange Notes of such series may declare the principal amount of the outstanding Exchange Notes of such series, and any accrued and unpaid interest through the date of such declaration, to be due and payable immediately; upon certain conditions such declarations may be annulled and past defaults (except for defaults in the payment of principal of, or any premium or interest on the Exchange Notes of such series and in compliance with certain covenants) may be waived by the holders of a majority in aggregate principal amount of the Exchange Notes of such series; and if an event of default described in clause (e) occurs and is continuing, then the principal amount of all Exchange Notes of such series outstanding, together with any accrued interest through the occurrence of such event, shall become and be due and payable immediately, without any declaration or other act by the trustee or any other holder.

“Significant Subsidiary” means any of Albemarle’s subsidiaries that would be a “Significant Subsidiary” of Albemarle within the meaning of Rule1-02 under RegulationS-X promulgated by the SEC.

Satisfaction and Discharge

An issuer can satisfy its obligations under the outstanding Exchange Notes of the applicable series and the indenture will cease to be of further effect (with limited exceptions) with respect to Exchange Notes of such series if such issuer puts in place the following arrangements for you to be repaid:

45

Modification and Waiver

There are three types of changes the issuers can make to the indenture and the Exchange Notes of the applicable series issued under the indenture.

Changes Requiring Your Approval. First, there are changes that cannot be made to the Exchange Notes without the approval of each holder affected thereby. Following is a list of those types of changes:

Changes Requiring a Majority Vote. The second type of change to the indenture or any supplement thereto and the Exchange Notes is the kind that requires a vote in favor by holders of a majority of the outstanding Exchange Notes affected by the change. Most other changes fall into this category, except for changes noted above as requiring the approval of the holders of each security affected thereby, and, as noted below, waivers and changes not requiring any approval.

The applicable issuer would need a vote by holders of Exchange Notes owning a majority of the principal amount of all series affected by the waiver, to obtain a waiver of certain of the restrictive covenants, including the covenants described above under “—Certain Covenants—Limitation on Liens and Other Encumbrances,” and “—Certain Covenants—Restrictions on Sale and Leaseback Transactions.” The applicable issuer also needs holders of Exchange Notes owning a majority of the principal amount of the relevant affected series to obtain a waiver of any past default with respect to such series, except a payment default listed in the first or second category described above under “—Events of Default.”

The indenture provides that a supplemental indenture that changes or eliminates any covenant or other provision of the indenture that has expressly been included solely for the benefit of one or more particular series of Exchange Notes, or that modifies the rights of the holders of Exchange Notes of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the indenture of the holders of securities of any other series.

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

Further Details Concerning Voting. Notes will not be considered outstanding, and therefore will not be eligible to vote, if the applicable issuer has deposited or set aside in trust for holders money for their payment or redemption or if they have been fully defeased, as described under “Defeasance—Legal Defeasance.” Notes owned by the applicable issuer or any of its affiliates will also not be considered outstanding or eligible to vote.

If an issuer determines to set a record date, such issuer will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding Exchange Notes of such series of Exchange Notes that are entitled to vote or take other action under the indenture. In some circumstances, the trustee will be entitled to set a record date for action by holders. If the trustee sets a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding Exchange Notes of that series on the record date and the action voted upon must be effective within 90 days following the record date.

46

Indirect holders should consult their banks or brokers for information on how approval may be granted or denied if any issuer seeks to change an indenture or the Exchange Notes or request a waiver.

Defeasance

Legal Defeasance

If there is a change in federal income tax law, as described below, an issuer can legally release itself from any payment or other obligations, with certain limited exceptions, on any series of Exchange Notes, called legal defeasance, if such issuer puts in place the following arrangements for you to be repaid:

There must be a change in current federal income tax law or a U.S. Internal Revenue Service ruling that lets such issuer make the above deposit without causing you to be taxed on the Exchange Notes of such series any differently than if such issuer did not make the deposit and just repaid the Exchange Notes of such series at maturity or redemption.

In the event of legal defeasance, you would have to rely solely on the trust holding the deposited cash and/or U.S. government Exchange Notes or bonds for repayment of the Exchange Notes of the applicable series. You could not look to the issuer for repayment in the unlikely event of any shortfall. Conversely, the trust would most likely be protected from claims of the issuer’s lenders and other creditors if the issuer ever become bankrupt or insolvent.

Covenant Defeasance

Under current federal income tax law, an issuer can make the same type of deposit described above under “— Defeasance—Legal Defeasance” and be released from some of the restrictive covenants in the Exchange Notes of the applicable series. This is called covenant defeasance. In that event, you would lose the protection of those restrictive covenants but would gain the protection of having cash and/or U.S. government notes or bonds set aside in trust to repay the Exchange Notes of such series. In order to achieve covenant defeasance, such issuer must do the following:

47

If an issuer accomplishes covenant defeasance, the following provisions, among others, of the indenture and the Exchange Notes of the applicable series would no longer apply:

If an issuer accomplishes covenant defeasance, you could still look to such issuer for repayment of the Exchange Notes if there were a shortfall in the trust. In fact, if one of the remaining events of default occurs, such as such issuer’s bankruptcy, and the Exchange Notes of such series become immediately due and payable, there may be a shortfall in the trust.

48

BOOK-ENTRY; DELIVERY AND FORM

Upon closing of the exchange offers, each series of the Exchange Notes will be represented by one or more fully registered global securities. Each such global security will be deposited with or on behalf of, DTC and registered in the name of DTC or a nominee thereof. Unless and until it is exchanged in whole or in part for Exchange Notes in definitive form, no global security may be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor of DTC or a nominee of such successor. Accountholders in the Euroclear Bank S.A./N.V. or Clearstream Banking, société anonyme clearance systems may hold beneficial interests in the Exchange Notes through the accounts that each of these systems maintain as participants in DTC.

So long as DTC or its nominee is the registered owner of the global securities, DTC or its nominee, as the case may be, will be the sole holder of the Exchange Notes represented thereby for all purposes under the indenture governing the Exchange Notes. Except as otherwise provided in this section, the beneficial owners of the global securities representing the Exchange Notes will not be entitled to receive physical delivery of certificated Exchange Notes and will not be considered the holders thereof for any purpose under the indenture, and the global securities representing the Exchange Notes shall not be exchangeable or transferable. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder under the indenture. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. Such limits and such laws may impair the ability to transfer beneficial interests in the global securities representing the Exchange Notes.

The global securities representing the Exchange Notes are exchangeable for certificated Exchange Notes of like tenor and terms and of differing authorized denominations aggregating a like amount only if:

Upon any such exchange, the certificated Exchange Notes shall be registered in the names of the beneficial owners of the global securities representing the Exchange Notes of the applicable series as provided by DTC’s relevant participants (as identified by DTC).

The description of the operations and procedures of DTC set forth below are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to change by them from time to time. The issuers do not take any responsibility for these operations or procedures, and investors are urged to contact the relevant system or its participants directly to discuss these matters.

The following is based on information furnished by DTC:

49

The information in this section concerning DTC and DTC’s system has been obtained from sources that the issuers believe to be reliable, but the issuers take no responsibility for the accuracy thereof. Transfers between participants in DTC will be effected in accordance with DTC’s procedures and will be settled insame-day funds.

MATERIAL INCOME TAX CONSEQUENCES

Material U.S. Federal Income Tax Consequences

The following discussion summarizes the material U.S. federal income tax consequences of an exchange of Restricted Notes for Exchange Notes pursuant to the exchange offers. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended, the Treasury regulations promulgated thereunder, judicial authority and administrative interpretations, all as of the date hereof and all of which are subject to change, possibly with retroactive effect, or different interpretations. This discussion does not address all of the tax considerations that may be relevant to a particular holder in light of the holder’s circumstances, or to certain categories of holders that may be subject to special rules. This summary does not consider any tax consequences arising under U.S. alternative minimum tax law, U.S. federal gift and estate tax law, the Medicare tax on certain net investment income or under the laws of any foreign, state, local or other jurisdiction.Each holder should consult its own independent tax advisor regarding its particular situation and the U.S. federal, state, local and foreign tax consequences of exchanging the Restricted Notes for Exchange Notes and purchasing, holding and disposing of the Exchange Notes, including the consequences of any proposed change in applicable laws.

The exchange of Restricted Notes for Exchange Notes in the exchange offers will not constitute a taxable event for U.S. federal income tax purposes. Consequently, for such purposes, a holder will not recognize gain upon receipt of an Exchange Note in exchange for a Restricted Note in the exchange offers, the holder’s adjusted tax basis (and adjusted issue price) in the Exchange Note received in the exchange offers will be the same as its adjusted tax basis (and adjusted issue price) in the corresponding Restricted Note immediately before the exchange, and the holder’s holding period in the Exchange Note will include its holding period in the Restricted Note.

Material Australian Income Tax Consequences

The following summary describes Australian income tax implications that may be relevant with respect to the acquisition, ownership and disposition of an exchange of Restricted Notes for Exchange Notes pursuant to the exchange offers.

Unless specifically stated otherwise, this section is relevant for noteholders who hold their notes on capital account for Australian income tax purposes. This section does not consider the Australian tax consequences for noteholders:

The information contained in this section is general in nature and should not be relied on by noteholders as tax advice. This section is not intended to be a complete statement of the taxation law applicable to the particular circumstances of every noteholder. Potential noteholders should obtain their own professional advice on the taxation consequences of purchasing the notes.

The information contained in this section is based on the taxation law at the date of this prospectus. The Australian taxation consequences outlined in this section may alter if there is a change in the taxation law after the date of this document. Each holder should consult its own independent tax advisor regarding its particular situation and the Australian and foreign tax consequences of exchanging the Restricted Notes for Exchange Notes and purchasing, holding and disposing of the Exchange Notes, including the consequences of any proposed change in applicable laws.

51

The exchange of Restricted Notes for Exchange Notes in the exchange offers will constitute a taxable event under Australian income tax law. The exchange should not give rise to amounts being subject to Australian income tax on the basis that the terms of the 2029 Exchange Notes largely reflect the terms of the 2029 Restricted Notes.

52

PLAN OF DISTRIBUTION

Any broker-dealer that holds Restricted Notes that were acquired for its own account as a result of market-making activities or other trading activities (other than Restricted Notes acquired directly from the issuers) may exchange such Restricted Notes pursuant to the exchange offers. Any such broker-dealer may, however, be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of Exchange Notes received by such broker-dealer in the exchange offers. Such prospectus delivery requirement may be satisfied by the delivery by such broker-dealer of this prospectus, as it may be amended or supplemented from time to time. The issuers have agreed to use commercially reasonable efforts to keep the registration statement, of which this prospectus forms a part, continuously effective for a period ending on the earlier of (i) 180 days from the date on which the registration statement related to the Exchange Notes is declared effective and (ii) the date on which a broker-dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities. The issuers have also agreed to provide sufficient copies of the latest version of this prospectus to broker-dealers promptly upon request at any time during such180-day period (or shorter as provided in the foregoing sentence) in order to facilitate such resales.

The issuers will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to the exchange offers may be sold from time to time in one or more transactions in theover-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers that may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the exchange offers and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Notes and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

The issuers have agreed to pay all expenses incident to the exchange offers other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Exchange Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.
