BACKGROUND

On October 25, 2018, pursuant to an Agreement and Plan of Merger, dated as of June 4, 2018 (the “Merger Agreement”), by and among us, Griffin Merger Sub, Inc., GitHub and Fortis Advisors LLC, as Stockholders’ Representative, we acquired GitHub. In that transaction, we paid an aggregate of 52,695,909 shares of our Common Stock to certain holders of capital stock of GitHub. Under the terms of the Merger Agreement, we agreed to file with the SEC a registration statement on Form S-3 covering the resale of the shares of Common Stock held by former holders of capital stock of GitHub.

Throughout this prospectus, when we refer to the shares of our Common Stock, the offer and sale of which are being registered on behalf of the selling stockholders, we are referring to the shares of Common Stock held by former holders of capital stock of GitHub that we agreed to register pursuant to the Merger Agreement. When we refer to the “selling stockholders” in this prospectus, we are referring to former holders of capital stock of GitHub.

RISK FACTORS

Investing in our Common Stock involves risks. Before making a decision to invest in our Common Stock, you should carefully consider the risks described under “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the fiscal year ended June 30, 2018, filed with the SEC on August 3, 2018, and our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2018, filed with the SEC on October 24, 2018, each of which are incorporated by reference in this prospectus, as well as any other risks described in our subsequent filings with the SEC. See “Where You Can Find More Information.”

USE OF PROCEEDS

All shares of Common Stock sold pursuant to this prospectus will be sold by the selling stockholders. We will not receive any of the proceeds from such sales.

SELLING STOCKHOLDERS

Up to 52,695,909 shares of Common Stock are being offered by this prospectus, all of which are being offered for resale for the account of the selling stockholders. The shares being offered were issued to the selling stockholders pursuant to the Merger Agreement.

We have prepared the following table based on information given to us by, or on behalf of, the selling stockholders on or before the date hereof with respect to the beneficial ownership of the shares of our Common Stock held by the selling stockholders as of October 25, 2018, the date of closing of our acquisition of GitHub. We have not independently verified this information. Because the selling stockholders may sell, transfer or otherwise dispose of all, some or none of the shares of our Common Stock covered by this prospectus, we cannot determine the number of such shares that will be sold, transferred or otherwise disposed of by the selling stockholders, or the amount or percentage of shares of our Common Stock that will be held by the selling stockholders upon termination of any particular offering. See the section of this prospectus captioned “Plan of Distribution” for additional information. For purposes of the table below, we assume that the selling stockholders will sell all their shares of Common Stock covered by this prospectus.

In the table below, the percentage of shares beneficially owned is based on 7,676,218,736 shares of our Common Stock outstanding as of October 19, 2018, determined in accordance with Rule 13d-3 under the Exchange Act of 1934, as amended. Under such rule, beneficial ownership includes any shares over which the selling stockholder has sole or shared voting power or investment power and also any shares that the selling stockholder has the right to acquire within 60 days of such date through the exercise of any options or other rights. Except as otherwise indicated, we believe that the selling stockholders have sole voting and investment power with respect to all shares of Common Stock shown as beneficially owned by them. The beneficial ownership information presented in this table is not necessarily indicative of beneficial ownership for any other purpose.

To our knowledge, except as may be disclosed in a prospectus supplement, none of the selling stockholders has or within the past three years has had, any position, office or other material relationship with us or any of our affiliates, except that certain of the selling stockholders (i) are or were employees of the successor of GitHub after it was acquired by us or (ii) have or had commercial arrangements with us in the ordinary course of business. To our knowledge, except as may be disclosed in a prospectus supplement, none of the selling stockholders are broker-dealers, nor at the time of the acquisition did any selling stockholders have direct or indirect agreements or understandings with any person to distribute any Common Stock.

PLAN OF DISTRIBUTION

The selling stockholders may, from time to time, sell any or all of the shares of Common Stock beneficially owned by them and offered hereby. The sales may be made on one or more exchanges, in the over-the-counter market or otherwise, at prices and at terms then prevailing or at prices related to the then current market price, or in negotiated transactions. The selling stockholders may effect such transactions by selling the shares of Common Stock to or through broker-dealers. The shares of Common Stock may be sold through broker-dealers by one or more of, or a combination of, the following:

• a block trade in which the broker-dealer so engaged will attempt to sell the shares of Common Stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• purchases by a broker-dealer as principal and resale by such broker-dealer for its account;

• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

• by agreement with broker-dealers to sell a specified number of shares of Common Stock at a stipulated price per share;

• short sales effected after the date the registration statement of which this prospectus is a part is becomes effective;

• through the writing or settlement of options or other hedging transactions, whether such options are listed on an options exchange or otherwise;

• in privately negotiated transactions;

• any other method permitted by applicable law and not prohibited by any agreement such selling stockholder has with us; and

• a combination of any such methods of sale.

The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

In connection with the Merger Agreement, certain of the selling stockholders have entered into agreements with us that, among other things, until January 24, 2019, and subject to certain exceptions, prohibit such selling stockholders from selling, offering, transferring, assigning, mortgaging, hypothecating, gifting, assigning or other similar method of disposing of or entering into or engaging in any hedge, swap, short sale, derivative transaction or other agreement or arrangement that transfers, in whole or in part, any of the economic consequences of shares of our Common Stock, without our prior written consent, provided that, the foregoing does not apply to 10% of such selling stockholders’ shares of our Common Stock upon the consummation of the Merger, an additional 30% of their shares of our Common Stock on November 25, 2018, an additional 30% of their shares of our Common Stock on December 25, 2018, and the remaining 30% of their shares of our Common Stock on January 24, 2019.

To the extent required, this prospectus may be amended or supplemented under Rule 424(b) or other applicable provision of the Securities Act from time to time to describe a specific plan of distribution.

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We are not aware of any agreement or understanding, directly or indirectly, between any selling stockholder and any person to distribute the shares covered by this prospectus. If any selling stockholder notifies us that a

4

material arrangement has been entered into with a broker-dealer for the sale of shares through a block trade, special offering or secondary distribution or a purchase by a broker or dealer, we may be required to file a prospectus supplement pursuant to the applicable rules promulgated under the Securities Act.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successor-in-interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus after they have provided to us certain documentation.

In connection with the sale of our shares of Common Stock, unless otherwise restricted by a contractual agreement or, in the case of a selling stockholder who is an employee, our insider trading policy, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of Common Stock in the course of hedging the positions they assume. The selling stockholders may also sell our shares of Common Stock short and deliver these securities to close out their short positions, or loan or pledge the shares of Common Stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares of Common Stock registered by this prospectus, which shares of Common Stock such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the shares of Common Stock offered by them will be the purchase price of the shares of Common Stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of shares of Common Stock to be made directly or through agents.

There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered pursuant to the shelf registration statement of which this prospectus forms a part.

To the extent required, the number of shares of Common Stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, shares of Common Stock may be sold in these jurisdictions only through registered or licensed brokers or dealers.

The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares of Common Stock against certain liabilities, including liabilities arising under the Securities Act.

We will bear all expenses incident to our obligation to register the shares of Common Stock covered by this prospectus pursuant to the Merger Agreement.

Once sold under the registration statement of which this prospectus forms a part, the shares of Common Stock will be freely tradeable in the hands of persons other than our affiliates.

However, as stated in their report included in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2018 and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their report on the unaudited interim financial information because the report is not “report” or a “part” of the Registration Statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.

Item 15. Indemnification of Directors and Officers

Sections 23B.08.510 and 23B.08.570 of the Washington Business Corporation Act (“WBCA”) authorizes Washington corporations to indemnify their officers and directors under certain circumstances against expenses and liabilities incurred in legal proceedings involving them as a result of their service as an officer or director. Section 23B.08.560 of the WBCA authorizes a corporation by provision in its articles of incorporation to indemnify or agree to indemnify a director made a party to a proceeding, or obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations imposed by Sections 23B.08.510 through .550 of the WBCA; provided, however, that no such indemnity shall be made for or on account of (a) acts or omissions of the director finally adjudged to be intentional misconduct or a knowing violation of law, (b) conduct of the director finally adjudged to be in violation of Section 23B.08.310 of the WBCA (relating to unlawful distributions) or (c) any transaction with respect to which it was finally adjudged that the director personally received a benefit in money, property, or services to which the director is not legally entitled.

The Registrant’s Amended and Restated Articles of Incorporation require indemnification of the Registrant’s officers and directors and advancement of expenses to the fullest extent not prohibited by applicable law. The Registrant’s Amended and Restated Articles of Incorporation provide for procedures for those seeking indemnification and/or advancement of expenses. In addition, as authorized by Section 23B.08.320 of the WBCA, the Registrant’s Amended and Restated Articles of Incorporation contain a provision eliminating the personal liability of directors to the Registrant or its shareholders for monetary damages for conduct as a director, except for (a) omissions involving intentional misconduct by the director or a knowing violation of law by the director, (b) conduct violating Section 23B.08.310 of the WBCA or (c) any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled.

The Registrant has established an indemnification trust (“2016 Directors’ Trust”) to fund the Registrant’s obligations to indemnify and/or advance expenses to directors arising from their board service in the event the Registrant does not or is financially unable to provide the indemnification and/or advancement. As required by the 2016 Directors’ Trust agreement, the Registrant has funded a minimum balance of principal assets of no less than $50 million in the trust. The Registrant also has an indemnification trust (“2016 Officers’ Trust”) that funds the Registrant’s indemnification obligations to certain past and present officers arising from their activities as such. As required by the 2016 Officers’ Trust agreement, the Registrant has funded a minimum balance of principal assets of no less than $50 million in the trust. The 2016 Directors’ Trust and 2016 Officers’ Trust are successors to certain trusts originally established in 1993, and amended from time to time, to fund Registrant’s indemnification obligations to directors and officers. The Registrant has also entered into separate indemnification agreements with certain of its directors and executive officers.

Item 17. Undertakings

The undersigned Registrant hereby undertakes:

(a)(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

II-2

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; and

(iii) Each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(b) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new

II-3

registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
