Eidos Therapeutics, Inc, or Eidos	5. Eidos Therapeutics, Inc, or Eidos From the date of BridgeBio’s initial investment until June 22, 2018, the Eidos IPO closing date, Eidos was determined to be a VIE and BridgeBio consolidated Eidos as the primary beneficiary. Subsequent to the Eidos IPO, BridgeBio determined that Eidos was no longer a VIE due to Eidos having sufficient equity at risk to finance its activities without additional subordinated financial support. From June 22, 2018, through January 26, 2021, BridgeBio determined that it held greater than 50% of the voting shares of Eidos and there were no other parties with substantive participating, liquidation or kick-out rights. BridgeBio consolidated Eidos under the VOE model until January 26, 2021, the date on which the Merger Transactions (as defined below) were consummated. On October 5, 2020, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with Eidos, Globe Merger Sub I, Inc., or Merger Sub, and Globe Merger Sub II, Inc. (the two latter companies being our indirect wholly-owned subsidiaries), providing for, in a series of merger transactions, or the Merger Transactions, the acquisition by us of all of the outstanding shares of common stock of Eidos, or the Eidos Common Stock, other than shares of Eidos Common Stock that (i) were owned by Eidos as treasury stock, (ii) were owned by us and our subsidiaries and, in each case, not owned on behalf of third parties and (iii) were subject to an Eidos Restricted Share Award (as defined below). Under the Merger Agreement, the stockholders of Eidos had the right to receive, at their election, either 1.85 shares of our common stock or $73.26 in cash per Eidos share in the transaction, subject to proration as necessary to ensure that the aggregate amount of cash consideration was no greater than $175.0 million. In addition, immediately prior to the effective time of the merger of Merger Sub with and into Eidos, or the Effective Time, (i) each option to purchase Eidos Common Stock, or an Eidos Option were to be converted into an option, on the same terms and conditions applicable to such Eidos Option immediately prior to the Effective Time, to purchase a specified number of shares of BridgeBio common stock, calculated pursuant to the terms of the Merger Agreement, and (ii) each outstanding award of shares of Eidos Common Stock that was subject to forfeiture conditions (subject to certain exceptions), or, each, an Eidos Restricted Share Award was to be converted into an award, on the same terms and conditions applicable to such Eidos Restricted Share Award immediately prior to the Effective Time, covering a number of whole restricted shares of BridgeBio common stock, calculated pursuant to the terms of the Merger Agreement, with any fractional shares being paid out to the holder of such Eidos Restricted Share Award in cash (conversion of the Eidos Option and the Eidos Restricted Share Awards collectively referred to as the “Eidos Awards Exchange”). On January 19, 2021, the stockholders of each of BridgeBio and Eidos voted to approve all proposals related to the Merger Transactions and on January 26, 2021, we closed and completed the Merger Transactions. The acquisition of the Eidos Common Stock was settled through an aggregate consideration of $1,651.6 million, which was comprised of cash payments of $21.3 million and the issuance of approximately 26,156,446 shares of our common stock, with a total fair value of $1,630.3 million. We accounted for the purchase of the outstanding Eidos Common Stock as acquisition of noncontrolling interest in accordance with ASC 810, Consolidation. Under ASC 810, the carrying amount of the Eidos noncontrolling interest was adjusted to reflect the change in our ownership interest, and the difference between the fair value of the consideration paid, and the amount by which the noncontrolling interest was adjusted was recognized in equity. Such difference recognized in equity amounted to $1,613.4 million and recorded as reduction in “Additional paid-in capital” for the year ended December 31, 2021. We continued to recognize the assets and liabilities of Eidos at their respective historical values as of the closing date of the Merger Transactions. Through the closing of the Merger Transactions, we have incurred transaction costs aggregating $70.7 million that were recorded in “Additional paid-in capital” for the year ended December 31, 2021. Upon closing and completion of the Merger Transactions with Eidos, Eidos became our wholly-owned subsidiary. Eidos’ common stock ceased to trade on The Nasdaq Global Select Market prior to the opening of business on January 26, 2021 and Eidos’ Certification and Notice of Termination of Registration under Section 12(g) of the Exchange Act was filed with the SEC on February 5, 2021.

From the date of BridgeBio’s initial investment until June 22, 2018, the Eidos IPO closing date, Eidos was determined to be a VIE and BridgeBio consolidated Eidos as the primary beneficiary. Subsequent to the Eidos IPO, BridgeBio determined that Eidos was no longer a VIE due to Eidos having sufficient equity at risk to finance its activities without additional subordinated financial support. From June 22, 2018, through January 26, 2021, BridgeBio determined that it held greater than 50% of the voting shares of Eidos and there were no other parties with substantive participating, liquidation or kick-out rights. BridgeBio consolidated Eidos under the VOE model until January 26, 2021, the date on which the Merger Transactions (as defined below) were consummated.

On October 5, 2020, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with Eidos, Globe Merger Sub I, Inc., or Merger Sub, and Globe Merger Sub II, Inc. (the two latter companies being our indirect wholly-owned subsidiaries), providing for, in a series of merger transactions, or the Merger Transactions, the acquisition by us of all of the outstanding shares of common stock of Eidos, or the Eidos Common Stock, other than shares of Eidos Common Stock that (i) were owned by Eidos as treasury stock, (ii) were owned by us and our subsidiaries and, in each case, not owned on behalf of third parties and (iii) were subject to an Eidos Restricted Share Award (as defined below).

In addition, immediately prior to the effective time of the merger of Merger Sub with and into Eidos, or the Effective Time, (i) each option to purchase Eidos Common Stock, or an Eidos Option were to be converted into an option, on the same terms and conditions applicable to such Eidos Option immediately prior to the Effective Time, to purchase a specified number of shares of BridgeBio common stock, calculated pursuant to the terms of the Merger Agreement, and (ii) each outstanding award of shares of Eidos Common Stock that was subject to forfeiture conditions (subject to certain exceptions), or, each, an Eidos Restricted Share Award was to be converted into an award, on the same terms and conditions applicable to such Eidos Restricted Share Award immediately prior to the Effective Time, covering a number of whole restricted shares of BridgeBio common stock, calculated pursuant to the terms of the Merger Agreement, with any fractional shares being paid out to the holder of such Eidos Restricted Share Award in cash (conversion of the Eidos Option and the Eidos Restricted Share Awards collectively referred to as the “Eidos Awards Exchange”).
