PROSPECTUS SUPPLEMENT

(To Prospectus dated November 17, 2021)

LOGO

Up to $240,000,000

Common Stock

This prospectus supplement and the accompanying base prospectus relate to the offer and sale from time to time of shares of our common stock, $0.001 par value per share, having an aggregate gross sales price of up to $240,000,000 through J.P. Morgan Securities LLC, Janney Montgomery Scott LLC, RBC Capital Markets, LLC and Wells Fargo Securities, LLC (each a “sales agent” and, collectively, the “sales agents”). These sales, if any, will be made pursuant to the terms of an equity distribution agreement dated as of November 17, 2021, between us and the sales agents (as amended from time to time, the “Equity Distribution Agreement”). The original Equity Distribution Agreement contemplated the offer and sale from time to time of shares of our common stock having an aggregate gross sales price of up to $100,000,000 through the sales agents in one or more “at-the-market” offerings, or directly to the sales agents as principals. Prior to Amendment No. 1 (as defined below), we sold an aggregate of $64,987,591.74 of shares our common stock under the Equity Distribution Agreement. On March 1, 2023, we entered into an Amendment No. 1 (“Amendment No. 1”) to the Equity Distribution Agreement so that, notwithstanding our prior sales, in accordance with the terms of the Equity Distribution Agreement, we may from time to time offer and sell shares of our common stock having an aggregate gross sales price of up to $240,000,000 (including the shares of our common stock having an aggregate gross sales price of up to $100,000,000 contemplated by the original Equity Distribution Agreement) through the sales agents as agents or principals.

Sales of shares of our common stock, if any, under this prospectus supplement and the accompanying prospectus may be made in sales deemed to be “at the market offerings” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including (1) by means of ordinary brokers’ transactions on the New York Stock Exchange (“NYSE”) at market prices prevailing at the time of sale, in negotiated transactions or as otherwise agreed by us, the applicable agent and the applicable investor, (2) to or through any market maker or (3) on or through any other national securities exchange or facility thereof, trading facility of a securities association or national securities exchange, alternative trading system, electronic communication network or other similar market venue.

Our common stock is listed on the New York Stock Exchange under the symbol “SJW.” On February 27, 2023, the closing price of our common stock, as reported on the New York Stock Exchange, was $77.74 per share.

Each sales agent will receive from us a commission of up to 2.0% of the gross sales price for any shares sold through it acting as our sales agent under the Equity Distribution Agreement. We have also agreed to reimburse the sales agents for certain of their expenses. We will designate the maximum number of common stock to be sold through the sales agent on a daily basis or otherwise as we and the sales agent may agree and the minimum price per share, if any, at which such common stock may be sold. Subject to the terms and conditions of the Equity Distribution Agreement, the sales agents will use their commercially reasonable efforts, consistent with their normal sales and trading practices, to sell on our behalf any shares of common stock to be offered by us. We may instruct the sales agents not to sell any common stock if the sales cannot be effected at or above the price designated by us in any such instruction. In connection with the sale of the shares of our common stock on our behalf, the sales agents may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the sales agents may be deemed to be underwriting commissions or discounts. See “Plan of Distribution.”

Under the terms of the Equity Distribution Agreement, we also may sell shares of our common stock to one or more of the sales agents as principals for their own account at a price agreed upon at the time of sale. If we sell shares to a sales agent as principal, we will enter into a separate terms agreement with such sales agent, and we will describe this agreement in a separate prospectus supplement or pricing supplement.

We or any sales agent may suspend the offering of our common stock by such sales agent by notifying the other party. The offering of common stock pursuant to the Equity Distribution Agreement will terminate upon the earliest of (1) the sale of the maximum amount of shares of our common stock subject to the Equity Distribution Agreement, (2) the termination of the Equity Distribution Agreement, pursuant to its terms, by either us or, with respect to any sales agent, such sales agent, at any time in the respective party’s sole discretion and (3) the third anniversary of the date of the original Equity Distribution Agreement. See “Plan of Distribution.”

Investing in our common stock involves a high degree of risk. You should review carefully the risks and uncertainties referenced under the heading “Risk Factors” on page S-5 of this prospectus supplement and in the documents that are incorporated by reference into this prospectus supplement.

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

Company Overview

SJW Group is a holding company with five wholly-owned subsidiaries: San Jose Water Company (“SJWC”), SJWNE LLC, SJWTX, Inc., SJW Land Company and SJWTX Holdings, Inc.

SJWC is a public utility in the business of providing water service to approximately 232,000 connections that serve a population of approximately one million people in an area comprising approximately 139 square miles in the metropolitan San Jose, California area.

The principal business of SJWC consists of the production, purchase, storage, purification, distribution, wholesale, and retail sale of water. SJWC provides water service to customers in portions of the cities of San Jose and Cupertino and in the cities of Campbell, Monte Sereno, and Saratoga and the Town of Los Gatos, and adjacent unincorporated territories, all in the County of Santa Clara in the State of California. SJWC distributes water to customers in accordance with accepted water utility methods which include pumping from storage and gravity feed from high elevation reservoirs. SJWC also provides non-tariffed services under agreements with municipalities and other utilities. These non-tariffed services include water system operations, maintenance agreements, and antenna site leases.

SJWC has utility property including land held in fee, impounding reservoirs, diversion facilities, wells, distribution storage, and all water facilities, equipment, office buildings and other property necessary to serve its customers. Under Section 851 of the California Public Utilities Code, properties currently used and useful in providing utilities services cannot be disposed of unless California Public Utilities Commission (“CPUC”) approval is obtained.

SJWNE LLC is the holding company for Connecticut Water Service, Inc. (“CTWS”). CTWS became a wholly-owned subsidiary of SJWNE LLC as part of the merger transaction between SJW Group and CTWS that was completed on October 9, 2019. CTWS, headquartered in Connecticut, serves as a holding company for water utility companies providing water service to approximately 141,000 connections that serve a population of approximately 459,000 people in 81 municipalities throughout Connecticut and Maine and more than 3,000 wastewater connections in Southbury, Connecticut. The subsidiaries held by CTWS that provide utility water services are The Connecticut Water Company (“Connecticut Water”) and The Maine Water Company (“Maine Water”).

TWOS was created for non-tariffed operations and is wholly-owned by SJWTX Holdings. SJWTX Holdings is a wholly-owned subsidiary of SJW Group, incorporated to hold the investments in SJWTX and TWOS. SJWTX Holdings intends to create a new subsidiary to hold future wholesale water supply assets in 2023.

RISK FACTORS

Investing in our common stock involves certain risks. In considering whether to purchase the common stock offered by this prospectus supplement, you should carefully consider the information included or incorporated by reference in this prospectus supplement and the accompanying prospectus. In particular, you should carefully consider the following risk factors. Please refer to the information under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022 and our Quarterly Reports on Forms 10-Q, which are incorporated by reference in this prospectus supplement and the accompanying prospectus.

It is not possible to predict the actual number of shares we will sell under the Equity Distribution Agreement, or the gross proceeds resulting from those sales.

Subject to certain limitations in the Equity Distribution Agreement and compliance with applicable law, we have the discretion to deliver an instruction to a designated sales agent at any time throughout the term of the Equity Distribution Agreement to sell shares of Common Stock. The number of shares that are sold through such designated sales agent after delivering an instruction will fluctuate based on a number of factors, including the market price of the Common Stock during the sales period, the limits we set with the designated sales agent in any applicable instruction, and the demand for our Common Stock during the sales period. Because the price per share of each share sold will fluctuate during the sales period, it is not currently possible to predict the number of shares that we will sell or the gross proceeds we will receive in connection with those sales.

The Common Stock offered hereby will be sold in “at the market offerings,” and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different levels of dilution and different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices and numbers of shares sold in this offering. In addition, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

Our stock price has fluctuated in the past and may fluctuate in the future.

The trading price of our common stock has fluctuated in the past. The trading price of our common stock could fluctuate significantly in the future and could be negatively affected in response to various factors, including:

•

market conditions in the broader stock market in general;

•

our ability to make investments with attractive risk-adjusted returns;

•

market perception of our current and projected financial condition, potential growth, future earnings and future cash dividends;

•

announcements we make regarding dividends;

•

actual or anticipated fluctuations in our quarterly financial and operating results;

•

additional offerings of our common stock or equity-linked securities;

•

actions by rating agencies;

•

short sales of our common stock;

•

any decision to pursue a distribution or disposition of a meaningful portion of our assets;

S-5

•

issuance of new or changed securities analysts’ reports or recommendations;

•

market perception or media coverage of us, other similar companies or the outlook of the markets and industries in which we compete;

•

major reductions in trading volumes on the exchanges on which we operate;

•

legislative or regulatory developments, including changes in the status of our regulatory approvals or licenses; and

•

litigation and governmental investigations.

These and other factors may cause the market price and demand for our common stock to fluctuate substantially, which may negatively affect the price or liquidity of our common stock.

When the market price of a stock has been volatile or has decreased significantly in the past, holders of that stock have, at times, instituted securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending, settling or paying any resulting judgments related to the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business and hurt our share price.

Our shares of common stock will rank junior to all of our consolidated liabilities.

In the event of a bankruptcy, liquidation, dissolution or winding up, our assets will be available to pay obligations on the common stock only after all of our consolidated liabilities have been paid. In the event of a bankruptcy, liquidation, dissolution or winding up, there may not be sufficient assets remaining, after paying our and our subsidiaries’ liabilities, to pay any amounts with respect to the common stock then outstanding. We have a significant amount of funded long-term debt, which amounted to $1,496,325 as of December 31, 2022, with $159,578 of short-term indebtedness under lines of credit. We may also take on additional long-term debt and working capital lines of credit to meet future financing needs, subject to certain restrictions under the terms of our existing debt.

SJW Group’s dividend policy is subject to the discretion of our board of directors and may be limited by legal and contractual requirements.

We anticipate continuing to pay a regular quarterly dividend, though any such determination to pay dividends will be at the discretion of our board of directors and will be dependent on then-existing conditions, including our financial condition, earnings, legal requirements, including limitations under Delaware law, restrictions in our credit agreements and other debt instruments that limit our ability to pay dividends to stockholders and other factors the board of directors deems relevant. The board of directors of SJW Group may, in its sole discretion, change the amount or frequency of dividends or discontinue the payment of dividends entirely. In addition, our subsidiaries may be subject to restrictions on their ability to pay dividends to us, including under state law, pursuant to regulatory commitments and under their credit agreements and other debt instruments. In this regard, SJWNE LLC, CTWS and its subsidiaries are limited from paying dividends to us in certain circumstances under the Connecticut Public Utilities Regulatory Authority and the Maine Public Utilities Commission regulatory commitments. Any inability of our subsidiaries to pay us dividends may have a material and adverse effect on our ability to pay dividends to our stockholders.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

Additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. We may

S-6

sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders.

In addition, sales of a substantial number of shares of our outstanding common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares of common stock intend to sell shares, could reduce the market price of our common stock. Significant portions of our shares are held by a relatively small number of stockholders. Sales by our stockholders of a substantial number of shares, or the expectation that such sales may occur, could significantly reduce the market price of our common stock.

We have broad discretion in the use of the net proceeds from this offering, and we may not use these proceeds effectively.

Our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not necessarily improve our results of operations or enhance the value of our common stock. We intend to use the net proceeds from the issuance and sale of our common stock in this offering for general corporate purposes. See “Use of Proceeds.” However, our management might not apply the net proceeds in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business or financial condition and cause the price of our common stock to decline.

S-7

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Statements contained or incorporated by reference in this prospectus supplement and the accompanying prospectus that are not statements of historical fact are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical fact included in this prospectus supplement and the accompanying prospectus are forward-looking statements made in good faith by us and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on management’s beliefs as well as assumptions made by, and information currently available to, management. When used in this prospectus supplement and the accompanying prospectus, the words “anticipate,” “believe,” “estimate,” “expect,” forecast,” “goal,�� “intend,” “objective,” “plan,” “projection,” “seek,” “strategy” or similar words are intended to identify forward-looking statements. Such forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the statements relating to our strategy, operations, markets, services, rates, recovery of costs, availability of water supply and other factors. These risks and uncertainties include the following:

•

the effect of water, utility, environmental and other governmental policies and regulations, including actions concerning rates, authorized return on equity, authorized capital structures, capital expenditures and other decisions;

•

changes in demand for water and other services;

•

unanticipated weather conditions and changes in seasonality, including those affecting water supply and customer usage;

•

the effects of climate change;

•

unexpected costs, charges or expenses;

•

our ability to successfully evaluate investments in new business and growth initiatives;

•

contamination of our water supplies and damage or failure of our water equipment and infrastructure;

•

the risk of work stoppages, strikes and other labor-related actions;

•

catastrophic events such as fires, earthquakes, explosions, floods, ice storms, tornadoes, hurricanes, terrorist acts, physical attacks, cyber-attacks, epidemics or similar occurrences;

•

changes in general economic, political, business and financial market conditions;

•

the ability to obtain financing on favorable terms, which can be affected by various factors, including credit ratings, changes in interest rates, compliance with regulatory requirements, compliance with the terms and conditions of our outstanding indebtedness, and general market and economic conditions; and

•

legislative and general market and economic developments.

All of these factors are difficult to predict and many are beyond our control. Accordingly, while we believe these forward-looking statements to be reasonable, there can be no assurance that they will approximate actual experience or that the expectations derived from them will be realized. Further, we undertake no obligation to update or revise any of our forward-looking statements, whether as a result of new information, future events or otherwise.

S-8

For additional factors you should consider, please see “Risk Factors” on page S-4 of this prospectus supplement, “Item 1A. Risk Factors” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. See also “Incorporation by Reference” on page S-17 of this prospectus supplement.

S-9

USE OF PROCEEDS

The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the Equity Distribution Agreement with the sales agents as a source of financing. Therefore, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We intend to use the net proceeds from future share issuances and sales from this offering, if any, for financing potential future acquisitions and for general corporate purposes, which may include, among other things, financing infrastructure improvements and other capital expenditures, repayment of debt or other corporate obligations, and working capital over the term of the Equity Distribution Agreement as such needs arise.

S-10

U.S. FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following is a summary of the U.S. federal income tax considerations generally applicable to the ownership and disposition of our common stock acquired in this offering by a Non-U.S. Holder (as defined below) as of the date hereof. This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, which we refer to as the “Code,” applicable U.S. Treasury regulations, judicial opinions, and administrative rulings and published positions of the Internal Revenue Service, or IRS, each as in effect as of the date hereof. These authorities are subject to change, possibly on a retroactive basis, and any such change could affect the accuracy of the statements and conclusions set forth in this summary.

For purposes of this summary, a “Non-U.S. Holder” means a beneficial owner of our common stock that is, for U.S. federal income tax purposes, neither a partnership (or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) nor any of the following:

•

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

•

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. A holder of our common stock that is a partnership and partners in such a partnership are urged to consult their tax advisors about the U.S. federal income tax considerations applicable to them in their particular circumstances.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to particular Non-U.S. Holders in light of their individual circumstances, including Non-U.S. Holders that are subject to special rules, such as U.S. expatriates, banks or other financial institutions, insurance companies, brokers or dealers in securities or currencies, traders that elect to mark-to-market their securities, controlled foreign corporations, passive foreign investment companies, Non-U.S. Holders subject to the alternative minimum tax, Non-U.S. Holders that currently own or have owned (actually or constructively) more than 5% of our common stock, or Non-U.S. Holders who hold shares of our common stock as part of a straddle, hedge, conversion transaction or other integrated investment. Such Non-U.S. Holders should consult their tax advisors to determine the U.S. federal, state, local and non-U.S. tax considerations applicable to the ownership and disposition of our common stock that may be relevant to them.

This summary does not discuss other U.S. federal tax consequences (e.g., estate or gift tax), any state, local, or non-U.S. tax considerations or the Medicare tax imposed on certain net investment income. In addition, this summary applies only to Non-U.S. Holders that hold our common stock as a capital asset within the meaning of the Code (generally, property held for investment purposes).

EACH NON-U.S. HOLDER IS URGED TO CONSULT ITS TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES TO IT OF OWNING AND DISPOSING OF OUR COMMON STOCK.

S-11

Distributions on common stock

Distributions with respect to our common stock will generally be treated as dividend income to the extent such distributions are paid from our current or accumulated earnings and profits as determined for U.S. federal income tax purposes. If a distribution exceeds our current and accumulated earnings and profits, the excess will generally be treated first as a return of capital to the extent of the Non-U.S. Holder’s adjusted tax basis in our common stock (and will reduce the Non-U.S. Holder’s basis in such common stock) and thereafter as capital gain from the sale or exchange of such common stock, subject to the tax treatment described below in “—Sale, Exchange or Other Taxable Disposition of Common Stock.” Generally, the gross amount of dividends paid to Non-U.S. Holders will be subject to withholding of U.S. federal income tax at a rate of 30% or at a lower rate if an applicable income tax treaty so provides and we (or our agent) have received proper certification as to the application of that treaty.

Dividends that are “effectively connected” with a Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment of the Non-U.S. Holder) are generally subject to U.S. federal income tax on a net basis at regular graduated rates, in the same manner as if the Non-U.S. Holder were a United States person (as defined in the Code), and are exempt from the 30% withholding tax described above, provided that certain certification requirements are satisfied. Any such effectively connected dividends received by a Non-U.S. Holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty.

To claim the benefits of an applicable income tax treaty or an exemption from withholding because the income is effectively connected with the conduct of a trade or business in the United States, a Non-U.S. Holder will generally be required to (a) provide a properly executed IRS Form W-8BEN or W-8BEN-E (if the holder is claiming the benefits of an income tax treaty) or IRS Form W-8ECI (for income effectively connected with the conduct of a trade or business in the United States) or other suitable form certifying under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if our common stock is held through certain foreign intermediaries, to satisfy the relevant certification and other requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals. A Non-U.S. Holder eligible for a reduced rate of withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the specific manner of claiming the benefits of the treaty.

Sale, exchange or other taxable disposition of common stock

Subject to the discussion below on Foreign Account Tax Compliance Act withholding, a Non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax with respect to gain realized on the sale, exchange or other taxable disposition of our common stock, unless:

•

in the case of a Non-U.S. Holder that is a non-resident alien individual, such Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale, exchange or other taxable disposition, and certain other conditions are met;

•

the gain is “effectively connected” with such Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable treaty, the gain is attributable to a U.S. permanent establishment of such Non-U.S. Holder); or

S-12

•

we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes at any time within the shorter of the five-year period ending on the date of such sale, exchange or other taxable disposition or the period that such Non-U.S. Holder held such common stock and either (a) our common stock was not treated as regularly traded on an established securities market during a relevant period in the calendar year in which the sale exchange, or other taxable disposition occurs, or (b) such Non-U.S. Holder owns or owned (actually or constructively) more than 5% of our common stock at any time during the shorter of the two periods described above.

If gain realized on the sale, exchange or other taxable disposition of our common stock is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable tax treaty, is attributable to a U.S. permanent establishment of such Non-U.S. Holder), such Non-U.S. Holder will generally be subject to U.S. federal income tax on the net gain from the disposition of our common stock at regular graduated rates in the same manner as if such Non-U.S. Holder were a United States person as defined in the Code. In the case of a Non-U.S. Holder that is a foreign corporation, such gain may also be subject to an additional branch profits tax rate of 30% (or a lower applicable treaty rate). If a Non-U.S. Holder is an individual that is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met, the Non-U.S. Holder will generally be subject to U.S. federal income tax at a rate of 30% (unless otherwise provided by an applicable treaty) on any capital gain recognized on the disposition of our common stock, which may be offset by certain U.S.-source capital losses.

Foreign Account Tax Compliance Act

Under Sections 1471 through 1474 of the Code, withholding at a rate of 30% will generally be required in certain circumstances on dividends in respect of shares of our common stock held by or through a “foreign financial institutions” (as specifically defined in the Code, including investment funds), unless such institution (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities or (iii) qualifies for an exemption. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which our common stock is held will affect the determination of whether such withholding is required. Similarly, dividends in respect of our common stock held by a Non-U.S. Holder that is a “non-financial foreign entity” (as specifically defined in the Code and whether such non-financial foreign entity is the beneficial owner or an intermediary) that does not qualify under certain exceptions generally will be subject to withholding at a rate of 30%, unless such entity either (x) certifies to the applicable withholding agent that such entity does not have any “substantial United States owners” or (y) provides certain information regarding the entity’s “substantial United States owners,” which information the applicable withholding agent will be required in turn to provide to the U.S. Department of Treasury. Prospective investors should consult their tax advisors regarding the possible implications of these rules on their investment in our common stock.

Backup withholding

A Non-U.S. Holder will not be subject to backup withholding on distributions received if such holder certifies under penalty of perjury that it is a Non-U.S. Holder (and the payor does not have actual knowledge or reason to know that such holder is a U.S. person), or such holder otherwise establishes an exemption.

S-13

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Information reporting

We are required to report annually to the IRS and to each Non-U.S. Holder the amount of any dividends paid to such Non-U.S. Holder, regardless of whether any tax was actually withheld. Copies of the information returns reporting such dividends and the amount withheld may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable income tax treaty. Non-U.S. Holders will generally be required to comply with certain certification procedures to establish that they are not U.S. persons in order to avoid information reporting with respect to proceeds received by such Non-U.S. Holders on the sale, exchange or other taxable disposition of our common stock within the United States or conducted through certain U.S.-related financial intermediaries.

S-14

PLAN OF DISTRIBUTION

We have entered into the Equity Distribution Agreement with the financial institutions named on the cover page of this prospectus supplement, as our sales agents, under which we may offer and sell over a period of time and from time to time our common stock having an aggregate offering price of up to $240,000,000 (including the shares of our common stock having an aggregate gross sales price of up to $100,000,000 contemplated by the original Equity Distribution Agreement). Sales of the shares to which this prospectus supplement relates, if any, will be made on the NYSE or otherwise at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices, in block transactions, or as otherwise agreed upon by us and the sales agents. The sales agents will not engage in any transactions that stabilize our common stock.

The sales agents will offer the shares of our common stock subject to the terms and conditions of the Equity Distribution Agreement on a daily basis or as otherwise agreed upon by us and the sales agents. We will designate the maximum number of shares of common stock to be sold through the sales agents on a daily basis or otherwise as we and the sales agents agree and the minimum price per share, if any, at which such common stock may be sold. None of the sales agents are required to sell any specific dollar amount of shares. Subject to the terms and conditions of the Equity Distribution Agreement, the sales agents will use their commercially reasonable efforts, consistent with their normal sales and trading practices, to sell on our behalf all of the designated shares of common stock. We may instruct the sales agents not to sell any shares of common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or any sales agent, with respect to itself only, may suspend the offering of our common stock by notifying the other party.

The sales agents will provide written confirmation to us no later than the opening of trading on the NYSE on the trading day immediately following each day on which shares of common stock are sold under the Equity Distribution Agreement. Each confirmation will include the number of shares of common stock sold on such day, the gross sales prices of such shares sold and the net proceeds to us with respect to such sales. We will report at least quarterly the number of shares of common stock sold through the sales agents under the Equity Distribution Agreement, the gross proceeds and the net proceeds to us (before expenses).

We will pay the sales agents an aggregate commission of up to 2.0% of the gross sales price per share of common stock sold under the Equity Distribution Agreement. The remaining net sales proceeds, after deducting any fees, transfer taxes or similar taxes or fees imposed by any governmental, regulatory or self-regulatory organization in respect of the sale, will equal our net proceeds for the sale of such shares. We have also agreed to reimburse the sales agents for certain of their expenses up to $50,000 in connection with the execution and delivery of Amendment No. 1 and, to the extent any sales are pending and not suspended on a bring-down delivery date, $35,000 in connection with each subsequent bring-down delivery date thereunder. We estimate that the total expenses for the offering (other than for offers of shares of common stock pursuant to the original Equity Distribution Agreement prior to Amendment No. 1), but excluding any sales agent’s commissions or expense reimbursement payable to the sales agents under the terms of the sales agreement, will be approximately $165,000.

Settlement of any sales of common stock will occur, unless the parties agree otherwise, on the second business day following the date on which such sales were made. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of our common stock as contemplated in this prospectus

S-15

supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and the sales agents may agree.

The offering of common stock pursuant to the Equity Distribution Agreement will terminate upon the earlier of (1) the sale of the maximum amount of shares of our common stock subject to the Equity Distribution Agreement, (2) the termination of the Equity Distribution Agreement, pursuant to its terms, by either us or, with respect to any sales agent, such sales agent, at any time in the respective party’s sole discretion and (3) the third anniversary of the date of the date of the original Equity Distribution Agreement. Additionally, if any party to the Equity Distribution Agreement has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the shares of our common stock, the sales of our shares pursuant to the Equity Distribution Agreement will be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

In connection with the sale of the shares of common stock on our behalf, each of the sales agents may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to each of the sales agents may be deemed to be underwriting commissions or discounts.

We have agreed to provide indemnification and contribution to the sales agents against certain liabilities, including civil liabilities under the Securities Act.

Other than in the United States, no action has been taken by us or the sales agents that would permit a public offering of the securities offered by this prospectus supplement in any jurisdiction where action for that purpose is required. The securities offered by this prospectus supplement may not be offered or sold, directly or indirectly, nor may this prospectus supplement or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction.

This prospectus supplement does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus supplement in any jurisdiction in which such an offer or a solicitation is unlawful.

The sales agents and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the sales agents and their respective affiliates have engaged, and may in the future engage, in investment banking, commercial banking and other financial advisory and commercial dealings with us and our affiliates. In particular, JPMorgan Chase Bank, N.A., an affiliate of J.P. Morgan Securities LLC, Wells Fargo Bank, National Association, an affiliate of Wells Fargo Securities, LLC, and Royal Bank of Canada, an affiliate of RBC Capital Markets, LLC, act as lenders to the Company, SJWC, SJWTX and CTWS under the Credit Agreement dated August 2, 2022.

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

THE COMPANY

SJW Group is a holding company with four wholly-owned subsidiaries: San Jose Water Company (“SJWC”), SJWNE LLC, SJWTX, Inc. and SJW Land Company.

SJWC is a public utility in the business of providing water service to approximately 231,000 connections that serve a population of approximately one million people in an area comprising approximately 139 square miles in the metropolitan San Jose, California area.

SJWC also has approximately 230 acres of nonutility property which has been identified as no longer used and useful in providing utility services. The majority of the properties are located in the hillside areas adjacent to SJWC’s various watershed properties.

SJWNE LLC is the holding company for Connecticut Water Service, Inc. (“CTWS”). CTWS became a wholly-owned subsidiary of SJWNE LLC as part of the merger transaction between SJW Group and CTWS that was completed on October 9, 2019. CTWS, headquartered in Connecticut, serves as a holding company for water utility companies providing water service to approximately 140,000 connections that serve a population of approximately 457,000 people in 81 municipalities throughout Connecticut and Maine and more than 3,000 wastewater connections in Southbury, Connecticut. The subsidiaries held by CTWS that provide utility water services are The Connecticut Water Company (“Connecticut Water”) and The Maine Water Company (“Maine Water”). The remaining two CTWS subsidiaries are Chester Realty, Inc., a real estate company in Connecticut, and New England Water Utility Services, Inc. (“NEWUS”), which provides contract water and sewer operations and other water related services. CTWS also offers Linebacker, an optional service line protection program to eligible residential customers through NEWUS in Connecticut and Maine.

The properties of CTWS’s subsidiaries consist of land, easements, rights (including water rights), buildings, reservoirs, standpipes, dams, wells, supply lines, water treatment plants, pumping plants, transmission and distribution mains and other facilities and equipment used for the collection, purification, storage and distribution of water throughout Connecticut and Maine. In certain cases, Connecticut Water and Maine Water are or may be a party to limited contractual arrangements for the provision of water supply from neighboring utilities.

SJWTX, Inc., doing business as Canyon Lake Water Service Company (“CLWSC”), is a public utility in the business of providing water service to approximately 22,000 connections that serve approximately 65,000 people. CLWSC’s service area comprises more than 248 square miles in the southern region of the Texas Hill Country in Blanco, Comal, Hays and Travis counties, the growing region between San Antonio and Austin, Texas. On July 1, 2021, CLWSC completed the asset purchase of Clear Water Estates Water System, LLC which added approximately 230 connections and 0.6 square miles to the service area. CLWSC has a 25% interest in

Acequia Water Supply Corporation (“Acequia”). The water supply corporation has been determined to be a variable interest entity within the scope of Accounting Standards Codification Topic 810 with CLWSC as the primary beneficiary. As a result, Acequia has been consolidated with CLWSC.

SJW Land Company owns undeveloped land and operates commercial buildings in Tennessee.

RISK FACTORS

Investing in the securities involves risk. See the risk factors described in our most recent Annual Report on Form 10-K (together with any material changes thereto contained in subsequently filed Quarterly Reports on Form 10-Q) and those contained in our other filings with the SEC that are incorporated by reference in this prospectus and any accompanying prospectus supplement or free writing prospectus. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus and any accompanying prospectus supplement or free writing prospectus. These risks could materially affect our business, financial condition or results of operations and cause the value of our securities to decline. You could lose all or part of your investment.

USE OF PROCEEDS

Except as otherwise set forth in any accompanying prospectus supplement, we expect to use the net proceeds from the sale of securities for general corporate purposes, including the financing of our operations, the possible repayment of indebtedness, and possible business acquisitions.

Unless set forth in an accompanying prospectus supplement, we will not receive any proceeds in the event that securities are sold by a selling securityholder.

The following summary description is not meant to be a complete description of our common stock. At the time of any offering and sale, this prospectus together with the accompanying prospectus supplement will contain the material terms of the securities being offered.

DESCRIPTION OF CAPITAL STOCK

General

The following summary description of our capital stock is based on the provisions of the Delaware General Corporation Law (the “DGCL”), our certificate of incorporation, as amended, and our bylaws, as amended. This description does not purport to be complete and is qualified in its entirety by reference to the full text of the DGCL, as it may be amended from time to time, and to the terms of our certificate of incorporation and bylaws, as each may be amended from time to time, which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.” As used in this “Description of Capital Stock,” the terms “SJW,” the “Company,” “we,” “our” and “us” refer to SJW Group, a Delaware corporation, and do not, unless otherwise specified, include our subsidiaries.

Our authorized capital stock consists of 70,000,000 shares of common stock, par value $0.001 per share, and 1,000,000 shares of preferred stock, par value $0.001 per share.

Common Stock

Each holder of record of our common stock is entitled to one vote for each share held on every matter properly submitted to our stockholders for their vote. Holders of our common stock do not have cumulative voting rights. After satisfaction of any dividend rights of holders of any outstanding preferred stock, holders of common stock are entitled ratably to any dividend declared by our board of directors out of funds legally available for this purpose.

Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive ratably our net assets available, if any, after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

Our common stock is not subject to further calls or assessments by SJW, and holders of our common stock have no preemptive, subscription, redemption, conversion or exchange rights and no sinking fund provisions.

The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

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

Preferred Stock

Our certificate of incorporation permits us to issue up to 1,000,000 shares of preferred stock, par value $0.001 per share, in one or more series, subject to limitations prescribed by law, with such designations, powers, preferences and rights, and the qualifications, limitations or restrictions thereof, of any wholly unissued series of preferred stock as our board of directors may determine, including without limitation, the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and liquidation preferences of any such series, and the number of shares constituting any such series and the designation thereof, or any of the foregoing.

Our board of directors is further authorized to increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares of any such series then outstanding) the number of shares of any series, the number of which was fixed by it, subsequent to the issuance of shares of such series then outstanding, subject to the powers, preferences and rights, and the qualifications, limitations and restrictions thereof stated in our certificate of incorporation or the resolution of our board of directors originally fixing the

number of shares of such series. If the number of shares of any series is so decreased, then the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution originally fixing the number of shares of such series.

Our common stock is subject to the express terms of any preferred stock. Our board of directors may issue preferred stock with voting, dividend, liquidation and other rights that could adversely affect the relative rights of the holders of our common stock.

Anti-Takeover Effects of Provisions of the Certificate of Incorporation, Bylaws and Other Agreements

Some provisions of Delaware law and our certificate of incorporation and bylaws may have an anti-takeover effect and may delay, defer or prevent a tender offer, proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by stockholders. In particular, these provisions may frustrate or prevent any attempts by stockholders of SJW to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of management.

A description of these provisions is set forth below.

Blank Check Preferred

As described above, our board of directors is authorized to create and issue from time to time, without stockholder approval, up to an aggregate of 1,000,000 shares of preferred stock in one or more series and to establish the number of shares of any series of preferred stock and to fix the designations, powers, preferences and rights of the shares of each series and any qualifications, limitations or restrictions of the shares of each series. The authority to designate preferred stock may be used to issue series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of our common stock or could also be used as a method of determining, delaying or preventing a change of control.

Meetings and Elections of Directors

Special Meetings of Stockholders. Our certificate of incorporation and bylaws limit the ability of stockholders to call a special meeting of stockholders to only stockholders holding not less than 20% of outstanding voting power. In particular, our certificate of incorporation and bylaws provide that special meetings of the stockholders may be called at any time by the chairman of the board, by the president, by resolution of our board of directors adopted by a majority of the total number of authorized directors (regardless of any vacancy), or by stockholders holding 20% or more of our voting power.

Stockholder Action by Written Consent. Our certificate of incorporation and bylaws provide that any action which may be taken at any annual or special meeting of stockholders may be taken without a meeting and without prior notice, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding shares having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. However, directors may not be elected by written consent except by unanimous written consent of all shares entitled to vote for the election of directors.

Vacancies. Our certificate of incorporation and bylaws provide that vacancies occurring on our board of directors for any reason and newly created directorships resulting from an increase in the authorized number of directors may be filled only by vote of a majority of the remaining members of our board of directors, although less than a quorum, or by a sole remaining director, at any meeting of our board of directors. A person so elected by our board of directors to fill a vacancy or newly created directorship shall hold office until the next succeeding annual meeting of stockholders and until his or her successor shall be duly elected and qualified or until his or her earlier resignation or removal.

No Cumulative Voting

Our certificate of incorporation prohibits cumulative voting in the election of directors.

Interested Stockholder Transaction and Business Combination

The provisions of Section 203 of the DGCL govern SJW. Section 203 of DGCL prohibits, subject to certain exceptions, a Delaware corporation from engaging in a business combination with an interested stockholder (i.e., a stockholder acquiring 15% or more of the outstanding voting stock) for three years following the date that such stockholder becomes an interested stockholder without approval of our board of directors. Section 203 makes certain types of unfriendly or hostile corporate takeovers, or other non-board approved transactions involving a corporation and one or more of its significant stockholders, more difficult by prohibiting large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time without the consent of our board of directors. Delaware companies may opt out of Section 203 if the original certificate of incorporation expressly elects not to be governed by Section 203. Our certificate of incorporation and bylaws do not “opt out” of Section 203.

Exclusive Delaware Forum

Our certificate of incorporation provides that unless SJW consents in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of SJW, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of SJW to SJW or SJW’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, or (iv) any action asserting a claim governed by the internal affairs doctrine shall be a state or federal court located within the State of Delaware, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants.

Advance Notice Bylaws

Our bylaws contain an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of persons for election to our board of directors. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given SJW’s corporate secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the annual meeting. Our bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of SJW.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “SJW.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company.

SELLING SECURITYHOLDERS

Information about selling securityholders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment or in filings we make with the SEC under the Exchange Act which are incorporated by reference into this prospectus.

PLAN OF DISTRIBUTION

We and any selling securityholder may offer and sell the securities covered by this prospectus from time to time, in one or more transactions, at market prices prevailing at the time of sale, at prices related to market prices, at a fixed price or prices subject to change, at varying prices determined at the time of sale or at negotiated prices, by a variety of methods, including the following:

•

through agents;

•

to or through underwriters;

•

in “at the market offerings,” within the meaning of Rule 415(a)(4) under the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;

•

through brokers or dealers;

•

directly by us or any selling securityholders to purchasers, including through a specific bidding, auction or other process; or

•

through a combination of any of these methods of sale.

Registration of the securities covered by this prospectus does not mean that those securities necessarily will be offered or sold.

In effecting sales, brokers or dealers engaged by us may arrange for other brokers or dealers to participate. Broker-dealer transactions may include:

•

purchases of the securities by a broker-dealer as principal and resales of the securities by the broker-dealer for its account pursuant to this prospectus;

•

ordinary brokerage transactions; or

•

transactions in which the broker-dealer solicits purchasers.

In addition, we and any selling securityholder may sell any securities covered by this prospectus in private transactions or under Rule 144 of the Securities Act rather than pursuant to this prospectus.

We may sell offered securities through agents designated by us from time to time. Any agent in the offer or sale of the securities for which this prospectus is delivered will be named, and any commissions payable by us to that agent will be set forth, in the applicable prospectus supplement. Unless indicated in such prospectus supplement, the agents will have agreed to use their reasonable best efforts to solicit purchases for the period of their appointment.

In connection with the sale of securities covered by this prospectus, broker-dealers may receive commissions or other compensation from us in the form of commissions, discounts or concessions. Broker-dealers may also receive compensation from purchasers of the securities for whom they act as agents or to whom they sell as principals or both. Compensation as to a particular broker-dealer may be in excess of customary commissions or in amounts to be negotiated. In connection with any underwritten offering, underwriters may receive compensation in the form of discounts, concessions or commissions from us or from purchasers of the securities for whom they act as agents. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Any underwriters, broker-dealers agents or other persons acting on our behalf that participate in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act, and any profit on the sale of the securities by them and any discounts, commissions or concessions received by any of those underwriters, broker-dealers agents or other persons may be deemed to be underwriting discounts and commissions under the Securities Act.

In connection with the distribution of the securities covered by this prospectus or otherwise, we or any selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of our securities in the course of hedging the positions they assume with us or any selling stockholder. We or any selling stockholder may also sell securities short and deliver the securities offered by this prospectus to close out our short positions. We or any selling securityholder may also enter into option or other transactions with broker-dealers or other financial institutions, which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus, as supplemented or amended to reflect such transaction. We or any selling securityholder may also from time to time pledge our securities pursuant to the margin provisions of our customer agreements with our brokers. Upon our default, the broker may offer and sell such pledged securities from time to time pursuant to this prospectus, as supplemented or amended to reflect such transaction.

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents, any discounts, commissions, concessions and other items constituting compensation from us and any discounts, commissions or concessions allowed or reallowed or paid to dealers. Such prospectus supplement, and, if necessary, a post-effective amendment to the registration statement of which this prospectus forms a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus. In order to comply with the securities laws of certain states, if applicable, the securities sold under this prospectus may only be sold through registered or licensed broker-dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is satisfied.

In connection with an underwritten offering, we and any selling stockholder would execute an underwriting agreement with an underwriter or underwriters. Unless otherwise indicated in the revised prospectus or applicable prospectus supplement, such underwriting agreement would provide that the obligations of the underwriter or underwriters are subject to certain conditions precedent, and that the underwriter or underwriters with respect to a sale of the covered securities will be obligated to purchase all of the covered securities, if any such securities are purchased. We or any selling securityholder may grant to the underwriter or underwriters an option to purchase additional securities at the public offering price, less any underwriting discount, as may be set forth in the revised prospectus or applicable prospectus supplement. If we or any selling securityholder grants any such option, the terms of that option will be set forth in the revised prospectus or applicable prospectus supplement.

To the extent that we make sales through one or more underwriters or agents in at the market offerings, we will do so pursuant to the terms of a sales agency financing agreement or other at the market offering arrangement between us and the underwriters or agents. If we engage in at the market sales pursuant to any such agreement, we will issue and sell our securities through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell securities on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The agreement will provide that any securities sold will be sold at prices related to the then prevailing market prices for our securities. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined as of the date of this prospectus. Pursuant to the terms of the agreement, we may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common stock or other securities. The terms of each such agreement will be set forth in more detail in a prospectus supplement.

Underwriters, agents, brokers or dealers may be entitled, pursuant to relevant agreements entered into with us, to indemnification by us or any selling securityholder against certain civil liabilities, including liabilities under the Securities Act that may arise from any untrue statement or alleged untrue statement of a material fact,

or any omission or alleged omission to state a material fact in this prospectus, any supplement or amendment hereto, or in the registration statement of which this prospectus forms a part, or to contribution with respect to payments which the underwriters, agents, brokers or dealers may be required to make.

LEGAL MATTERS

Certain legal matters relating to the issuance and sale of the securities offered hereby will be passed upon for us by Morgan, Lewis & Bockius LLP, Palo Alto, California. Any underwriters will also be advised about legal matters by their own counsel, which will be named in the prospectus supplement.
