Joint Venture

Joint Venture

In May 2018, the Company and an affiliate of SoftBank formed and capitalized Guardant Health AMEA, Inc., the Joint Venture, for the sale, marketing and distribution of the Company’s tests generally outside the Americas and Europe, and to accelerate commercialization of its products in Asia, the Middle East and Africa. Under the terms of the joint venture agreement, each party held an approximately 50% ownership interest in the Joint Venture and two seats on the board of the Joint Venture.

The joint venture agreement included a put-call arrangement with respect to the shares of the Joint Venture held by SoftBank and its affiliates. Under certain specified circumstances and on terms specified in the joint venture agreement, including timely written notice, SoftBank had the right to cause the Company to purchase all shares of the Joint Venture held by SoftBank and its affiliates, or the put right, and the Company had a right to purchase all such shares, or the call right.

Prior to November 2021, the noncontrolling interest held by SoftBank contained embedded put-call redemption features that were not solely within the Company’s control and had been classified outside of permanent equity in the consolidated balance sheets. The put-call feature embedded in the redeemable noncontrolling interest did not require bifurcation as it did not meet the definition of a derivative and was considered to be clearly and closely related to the redeemable noncontrolling interest. The Company elected to recognize the changes in redemption value immediately as they occur as if the put-call redemption feature were exercisable at the end of the reporting period. The adjustment of redeemable noncontrolling interest was recorded as an adjustment to net loss attributable to Guardant Health, Inc. common stockholders in the Company's consolidated statement of operations.

In November 2021, the Company exercised its call right contained in the joint venture agreement with SoftBank to purchase all of the shares held by SoftBank and its affiliates in consideration for the payment of the aggregate purchase price to be determined based on an independent third-party valuation. Upon the Company's exercise of the call right in November 2021, SoftBank no longer had the option to exercise its put right. In connection with exercising the call right, the Company reclassified $78.0 million from redeemable noncontrolling interest to noncontrolling interest liability.

In June 2022, the Company purchased all of the shares held by SoftBank and its affiliates in consideration for a cash payment of the aggregate purchase price of $177.8 million, which resulted in $99.8 million of fair value adjustments to the noncontrolling interest liability for the year ended December 31, 2022. In connection with the Joint Venture Acquisition, the Company also issued a tender offer to purchase the Joint Venture's Class B common stock issued and issuable upon exercise of vested Joint Venture's stock options held by the Joint Venture's employees (see Note 11, Stock-Based Compensation).

Prior to the completion of the Joint Venture Acquisition, the Joint Venture was deemed to be a VIE, and the Company had been identified as the VIE’s primary beneficiary. As the primary beneficiary, the Company had consolidated the financial position, results of operations and cash flows of the Joint Venture in its financial statements and all intercompany balances had been eliminated in consolidation. Upon completion of the Joint Venture Acquisition and the tender offer, Guardant Health AMEA, Inc. became the Company's wholly owned subsidiary.
