About this prospectus supplement

This prospectus supplement and the accompanying prospectus are each part of an automatic shelf registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, as a “well-known seasoned issuer,” as defined in Rule 405 of the Securities Act of 1933, as amended, or the Securities Act. Under the shelf registration process, we may from time to time offer and sell to the public any or all of the securities described in the registration statement in one or more offerings. This document is in two parts. The first part, which is this prospectus supplement, describes the specific terms of the securities that we are offering and other matters relating to us. The second part, which is the accompanying prospectus, gives more general information about securities we may offer from time to time, some of which may not apply to the securities offered by this prospectus supplement. Generally when we refer to the prospectus supplement, we are referring to both parts combined. This prospectus supplement may add to, update or change the information in the accompanying prospectus.

The offering

The summary below contains basic information about this offering. It does not contain all of the information you should consider in making your investment decision. You should read this entire prospectus supplement and the accompanying prospectus and the information included or incorporated by reference herein and therein before making an investment decision.

Issuer SJW Group, a Delaware corporation.

Approximate number of shares to be outstanding after this offering 29,629,414 shares.

Underwriters’ option We have granted the underwriters a 30-day option to purchase up to 154,500 additional shares of our common stock at the public offering price, less the underwriting discounts and commissions.

Use of proceeds We estimate that the net proceeds from this offering will be approximately $58.2 million (or approximately $66.9 million if the underwriters exercise their option to purchase additional shares in full), after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering to repay approximately $50 million due under the Credit Agreement, dated as of June 1, 2016, between San Jose Water Company and JPMorgan Chase Bank, N.A., as amended, or the SJWC Credit Facility.

Conflicts of interest To the extent we use all or a portion of the net proceeds to repay outstanding borrowings under the SJWC Credit Facility, affiliates of certain underwriters may receive at least 5% of the net offering proceeds of this offering in connection with any such repayment. Accordingly, this offering is being made in compliance with the requirements of Financial Industry Regulatory Authority (“FINRA”) Rule 5121. Since the common stock offered hereby has a bona fide public market, pursuant to FINRA Rule 5121, the appointment of a qualified independent underwriter is not necessary.

Risk factors

An investment in our common stock involves a number of risks. You should read this entire prospectus supplement and the accompanying prospectus and the information included or incorporated by reference herein, including the most recent Annual Report on Form 10-K for the year ended December 31, 2020, and therein before making an investment decision. In particular, we urge you to consider carefully the factors set forth below and such risk factors as may be updated from time to time in our public filings. Any of these risks could materially and adversely affect our business, financial condition, results of operations and prospects and the actual outcome of matters as to which forward-looking statements are made in this prospectus supplement and the accompanying prospectus. As a result, the trading price of our common stock could decline, and you could lose some or all of your investment. While we believe we have identified and discussed below, in the accompanying prospectus and in the documents incorporated by reference herein and therein the material risks affecting our business, there may be additional risks and uncertainties that we do not presently know or that we do not currently believe to be material that may adversely affect our business, financial condition, results of operations and prospects in the future.

Risks related to this offering and the ownership of our common stock

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;

• 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.

S-5

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 debt, which amounted to $1.29 billion as of December 31, 2020, with $175.1 million 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 to continue 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 PURA and MPUC 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.

S-6

Use of proceeds

We estimate that the net proceeds from this offering will be approximately $58.2 million (or approximately $66.9 million if the underwriters exercise their option to purchase additional shares in full), after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering to repay approximately $50 million due under the Credit Agreement, dated as of June 1, 2016, between San Jose Water Company and JPMorgan Chase Bank, N.A., as amended, or the SJWC Credit Facility. As of March 5, 2021, the total amount outstanding under the SJWC Credit Facility was $95 million, bore interest at 1.55% and is due on June 1, 2021. Amounts borrowed under the SJWC Credit Facility have been used for general corporate purposes of San Jose Water Company, including among other things, financing infrastructure improvements and other capital expenditures, acquisitions of adjacent water systems and working capital. We intend to use the remaining net proceeds for general corporate purposes, which may include, among other things, financing infrastructure improvements and other capital expenditure, repayment of debt or other corporate obligations and working capital.

See “Risk factors—Risks related to this offering and the ownership of our common stock—SJW Group’s dividend policy is subject to the discretion of our board of directors and may be limited by legal and contractual requirements.”

S-9

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-10

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-11

• 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-12

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-13

Certain ERISA considerations

The following is a summary of certain considerations associated with the purchase of shares of our common stock by (i) employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under any other U.S. or non-U.S. federal, state, local or other laws or regulations that are similar to such provisions of the Code or ERISA (collectively, “Similar Laws”), and (iii) entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each as described in clauses (i), (ii) and (iii) referred to herein as a “Plan”).

General fiduciary matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (each, a “Covered Plan”) and prohibit certain transactions involving the assets of a Covered Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such a Covered Plan or the management or disposition of the assets of such a Covered Plan, or who renders investment advice for a fee or other compensation to such a Plan, is generally considered to be a fiduciary of the Covered Plan.

In considering an investment in shares of our common stock with the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Prohibited transaction issues

Section 406 of ERISA and Section 4975 of the Code prohibit Covered Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available, of which there are many. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the Covered Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and/or the Code. Fiduciaries of Covered Plan considering acquiring our common stock in reliance on an exemption should carefully review the exemption to assure it is applicable.

Non-U.S. plans (as described in Section 4(b)(4) of ERISA), governmental plans (as defined in Section 3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA), while not subject to the fiduciary responsibility provisions of ERISA or the prohibited transaction provisions of ERISA and Section 4975 of the Code, may nevertheless be subject to Similar Laws. Fiduciaries of any such plans should consult with their counsel before purchasing shares of our common stock to determine the need for, and the availability of, any exemptive relief under applicable Similar Law.

Representation

Accordingly, by acceptance of shares of our common stock, each purchaser and subsequent transferee of the shares of common stock will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire shares of our common stock constitutes assets of any

S-14

Plan or (ii) the purchase of shares of our common stock by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all-inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing shares of our common stock on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of shares of our common stock.

Purchasers of shares of common stock have the exclusive responsibility for ensuring that their purchase complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA, the Code or applicable Similar Laws. In this regard, neither this discussion nor anything provided in this Prospectus Supplement is or is intended to be investment advice directed at any potential Plan purchasers, or at Plan purchasers generally, and such purchasers of any shares or our common stock should consult and rely on their own counsel and advisers as to whether an investment in our common stock is suitable for the Plan.

S-15

Underwriting (conflicts of interest)

We and the underwriters for this offering named below have entered into an underwriting agreement dated as of the date of this prospectus supplement with respect to the shares of common stock being offered under this prospectus supplement. J.P. Morgan Securities LLC is acting as the representative of each of the underwriters of this offering. Under the terms and subject to the conditions contained in the underwriting agreement, each underwriter has severally agreed to purchase, and we have agreed to sell, the number of shares of our common stock set forth opposite the underwriter’s name:

The underwriting agreement also provides that the underwriters are obligated to purchase all the shares of common stock in this offering if any are purchased, other than those shares covered by the underwriters’ option to purchase additional shares described below.

S-16

A prospectus supplement in electronic format may be made available on the websites maintained by one or more of the underwriters, or selling group members, if any, participating in this offering, and one or more of the underwriters participating in this offering may distribute prospectuses electronically. The representative may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters and selling group members that will make internet distributions on the same basis as other allocations.

No sales of similar securities

We have agreed that, subject to certain exceptions, we will not (i) offer, pledge, lend, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or file with, or submit to, the SEC a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of our common stock or such other securities (regardless of whether any of these transactions are to be settled by the delivery of shares of common stock or such other securities, in cash or otherwise), without the prior written consent of J.P. Morgan Securities LLC, for a period of 60 days after the date of this prospectus supplement.

Our directors and executive officers have entered into lock up agreements with the underwriters prior to the commencement of this offering pursuant to which each of these persons or entities, with certain exceptions, for a period of 60 days after the date of this prospectus supplement, may not, without the prior written consent of J.P. Morgan Securities LLC:

(1)    offer, pledge, lend, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock (including, without limitation, common stock or such other securities which may be deemed to be beneficially owned by such directors and executive officers in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant), or

(2)    enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise, or

(3)    make any demand for or exercise any right with respect to the registration of any shares of our common stock or any security convertible into or exercisable or exchangeable for our common stock.

Indemnification

We have agreed to indemnify the underwriters against liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in that respect.

Underwriter activities

In connection with this offering, the underwriters may engage in stabilizing transactions, which involve making bids for, purchasing and selling shares of our common stock in the open market for the purpose of preventing

S-17

or retarding a decline in the market price of our common stock while this offering is in progress. These stabilizing transactions may include making short sales of our common stock, which involve the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares of common stock, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through their option. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of our common stock, including the imposition of penalty bids. This means that if the representative of the underwriters purchases common stock in the open market in stabilizing transactions or to cover short sales, the representative can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock, and, as a result, the price of our common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the New York Stock Exchange, in the over the counter market or otherwise.

This prospectus is part of an “automatic shelf” registration statement that we filed with the Securities and Exchange Commission (the “SEC”) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using a “shelf” registration process.

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 36,000,000 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.

4

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

5

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

6

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.

7

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.

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 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.

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.
