We are involved in a number of legal proceedings concerning matters arising in connection with the conduct of our business activities, some of which are at preliminary stages and some of which seek an indeterminate amount of damages. We regularly evaluate the status of legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made if accruals are not appropriate. For certain cases described below, management is unable to provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons, (i) the proceedings are in preliminary stages; (ii) specific damages have not been sought; (iii) damages sought are, in our view, unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant factual issues to be resolved; and/or (vi) there are novel legal issues or unsettled legal theories presented. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material effect on our financial position, results of operations or cash flow. For the matters discussed below, we have not recorded any material accruals as of June 30, 2026 or December 31, 2025.

On September 17, 2019, International Business Machines Corporation (“IBM”) filed a complaint against us in the U.S. District Court for the Central District of California, alleging, among other things, that the Company has infringed and continues to willfully infringe seven patents held by IBM and seeks unspecified damages, including a request that the amount of compensatory damages be trebled, injunctive relief and costs and reasonable attorneys’ fees. Our motion to transfer venue to the U.S. District Court for the Western District of Washington (the “Court”) was granted on May 28, 2020. On November 25, 2022, Zillow filed a motion to join an Inter Partes Review (“IPR”) petition within Ebates Performance Mktg., Inc. d/b/a Rakuten Rewards v. Int’l Bus. Machs. Corp. (“Rakuten IPR”), IPR2022-00646 concerning one patent in this action, which the Court granted on April 20, 2023. On October 11, 2023, the U.S. Patent and Trial Appeal Board (“PTAB”) ruled on the Rakuten IPR finding the claims of the patent asserted against Zillow unpatentable. IBM appealed the PTAB’s decision on November 21, 2023 (the “PTAB Appeal”), and cross appeals were filed by Ebates Performance Marketing Inc. on November 21, 2023 and by us on December 15, 2023. On March 20, 2024, IBM voluntarily dismissed all claims filed in this action against Zillow with prejudice, with the exception of those pertaining to the patent asserted within the pending PTAB Appeal. On June 21, 2024 we filed our response to the PTAB Appeal. On July 30, 2024, IBM filed its reply in further support of the PTAB Appeal. On September 3, 2024, we filed our reply in further support of our cross-appeal. On December 9, 2025, the Federal Circuit issued an order affirming the October 11, 2023 PTAB decision in full. On April 17, 2026, we filed our motion for summary judgment. On June 30, 2026, the Court issued an order denying Zillow’s motion. In July 2026, the parties reached an agreement in principle to resolve all remaining claims in this action, the impact of which will not be material to the Company.

On November 16, 2021, November 19, 2021 and January 6, 2022, three purported class action lawsuits were filed against us and certain of our executive officers, alleging, among other things, violations of federal securities laws on behalf of a class of those who purchased our stock between August 7, 2020 and November 2, 2021. The three purported class action lawsuits, captioned Barua v. Zillow Group, Inc. et al., Silverberg v. Zillow Group, et al. and Hillier v. Zillow Group, Inc. et al. were brought in the Court and were consolidated on February 16, 2022 (the “Federal Securities Suit”). On May 12, 2022, the plaintiffs filed their amended consolidated complaint which alleges, among other things, that we issued materially false and misleading statements regarding our Zillow Offers business. The complaints seek to recover, among other things, alleged damages sustained by the purported class members as a result of the alleged misconduct. On December 7, 2022, the Court

rendered its decision granting our previously filed motion to dismiss, in part, and denying the motion, in part. On January 23, 2023, we filed our answer to the consolidated complaint. On March 14, 2024, plaintiffs filed a motion for class certification, which was granted on August 23, 2024. On September 6, 2024, we filed a petition for permission to appeal the class certification order, on September 16, 2024, plaintiffs filed their opposition to our petition, and on September 23, 2024, we filed our reply in further support of the petition. On October 24, 2024, the Ninth Circuit issued an order granting Zillow permission to appeal. On November 1, 2024, the Court issued an order staying the Federal Securities Suit pending the outcome of the appeal, which was extended on October 10, 2025. On January 8, 2025, we filed our opening brief in the appeal. On March 10, 2025, plaintiffs filed their response brief, and on April 30, 2025, we filed our reply brief. On September 26, 2025, the Ninth Circuit affirmed the Court’s class certification. On October 24, 2025, we filed an en banc petition before the Ninth Circuit seeking rehearing of the Ninth Circuit’s September 26, 2025 decision. On January 6, 2026, the Ninth Circuit issued an order denying Zillow’s en banc petition. On June 5, 2026, Zillow filed a petition for certiorari before the Supreme Court of the United States. On June 25, 2026, the Supreme Court mandated that plaintiffs respond to Zillow’s petition. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in this consolidated lawsuit.

On March 10, 2022, May 5, 2022, July 20, 2022 and October 31, 2024, shareholder derivative suits were filed in the Court and on July 25, 2022, a shareholder derivative suit was filed in the Superior Court of the State of Washington, King County, against us and certain of our executive officers and directors seeking unspecified damages on behalf of the Company and certain other relief, such as reform to corporate governance practices. The plaintiffs (including the Company as a nominal defendant) allege, among other things, that the defendants breached their fiduciary duties by failing to maintain an effective system of internal controls, which purportedly caused the losses the Company incurred when it decided to wind down Zillow Offers operations. Plaintiffs also allege, among other things, violations of Section 14(a) and Section 20(a) of the Exchange Act, insider trading and waste of corporate assets. On August 23, 2023, a second shareholder derivative suit was filed in the Superior Court of the State of Washington, King County. These shareholder derivative lawsuits have since been stayed by the relevant courts and they remain stayed as of June 30, 2026. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable. The defendants deny the allegations of any wrongdoing and vigorously defend the claims in these lawsuits.

On September 30, 2025, the FTC filed a complaint in the U.S. District Court for the Eastern District of Virginia against Zillow Group, Inc., Zillow, Inc., and Redfin Corporation. On October 1, 2025, the Attorneys General of the Commonwealth of Virginia and the States of Arizona, Connecticut, New York, and Washington (collectively, “the States”) filed a similar complaint against the same parties in the same court. The complaints allege that the partnership entered into between Zillow and Redfin on February 6, 2025 (the “Redfin Partnership”) harmed competition for online multifamily rental-listings in violation of federal antitrust laws. The complaints of the FTC and the States both seek a permanent injunction and seek other equitable relief, including, among other things, a divestiture of assets or reconstruction of businesses, and other relief sufficient to restore the competition that would exist absent the anticompetitive conduct alleged. The complaint of the States also seeks an award of costs of the lawsuit, including reasonable attorneys’ fees. We filed our motion to dismiss on January 13, 2026. Plaintiffs filed their opposition to our motion to dismiss on February 3, 2026. On February 12, 2026, we filed our reply in further support of our motion to dismiss, and on May 6, 2026, the court denied the motion.

On June 24, 2026, we filed our opposition to the motion, and on June 30, 2026, the FTC and the States filed their reply. On July 8, 2026, oral argument on the motion was held, and the court denied the motion in its entirety. Trial is set to begin on August 24, 2026. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in these lawsuits.

Zillow Group, Inc. et al., was filed against us and certain of our executive officers in the U.S. District Court for the Western District of Washington.

On June 22, 2026, the parties filed a stipulation staying deadlines pending the appointment of a lead plaintiff and lead counsel and the filing of an amended or other operative complaint.

On July 13, 2026 and July 14, 2026, shareholder derivative suits were filed in the U.S. District Court for the Western District of Washington against certain of our executive officers and directors, with the Company named as a nominal defendant, seeking unspecified damages on behalf of the Company and certain other relief, such as reform to corporate governance practices.

In addition to the matters discussed above, from time to time, we are involved in litigation and claims that arise in the ordinary course of business. Although we cannot be certain of the outcome of any such litigation or claims, nor the amount of damages and exposure that we could incur, we currently believe that the final disposition of such matters will not have a material effect on our business, financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

In the ordinary course of business, we enter into contractual arrangements under which we agree to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters. For additional information regarding our indemnifications, see Note 13 in the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.
