Accounting Policies [Abstract] |
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements include the accounts of BridgeBio Pharma, Inc. and its wholly-owned subsidiaries and controlled entities, substantially all of which are denominated in U.S. dollars. All intercompany balances and transactions have been eliminated in consolidation. For consolidated entities where we own or are exposed to less than 100% of the economics, we record "Net loss attributable to redeemable convertible noncontrolling interests and noncontrolling interests" in our condensed consolidated statements of operations equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. In determining whether an entity is considered a controlled entity, we applied the VIE and Voting Interest Entity (“VOE”) models. We assess whether we are the primary beneficiary of a VIE based on our power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and our obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. Entities that do not qualify as a VIE are assessed for consolidation under the VOE model. Under the VOE model, BridgeBio consolidates the entity if it determines that it has a controlling financial interest in the entity through its ownership of greater than 50% of the outstanding voting shares of the entity and that other equity holders do not have substantive voting, participating or liquidation rights. We assess whether we are the primary beneficiary of a VIE or whether we have a majority voting interest for entities consolidated under the VOE model at the inception of the arrangement and at each reporting date. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC. The condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of our financial position, our results of operations and comprehensive loss, stockholders’ deficit and our cash flows for the periods presented. The results of operations for the three months ended March 31, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future annual or interim periods.
Cash, Cash Equivalents and Marketable Securities | Cash, Cash Equivalents and Marketable Securities We consider all highly liquid investments purchased with original maturities of 90 days or less from the purchase date to be cash equivalents. Cash equivalents consist primarily of amounts invested in money market instruments, such as money market funds and repurchase agreements collateralized with securities issued by the U.S. government or its agencies. Our marketable securities consist of high investment grade fixed income securities that are primarily invested in commercial paper, corporate bonds, and U.S. government securities. We classify our marketable securities as available-for-sale securities and report them at fair value in cash equivalents or marketable securities on the condensed consolidated balance sheets with related unrealized gains and losses included as a component of stockholders’ deficit. We classify our marketable securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity which is included in interest income on the condensed consolidated statements of operations. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in "Other expense, net". The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income. Our cash, cash equivalents and marketable securities are exposed to credit risk in the event of default by the third parties that hold or issue such assets. Our cash, cash equivalents and marketable securities are held by financial institutions that management believes are of high credit quality. Our investment policy limits investments to fixed income securities denominated and payable in U.S. dollars such as corporate bonds, corporate commercial paper, U.S. government obligations, and money market funds, and places restrictions on maturities and concentrations by type and issuer. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the condensed consolidated balance sheets to the total amounts shown in the condensed consolidated statements of cash flows:
|  | March 31, 2023 |  |  | December 31, 2022 |
|  | (in thousands) |
Cash and cash equivalents |  | $ | 407,368 |  |  | $ | 376,689 |
Restricted cash |  |  | 25,503 |  |  |  | 37,930 |
Restricted cash, non-current — included in “Other assets” |  |  | 2,238 |  |  |  | 2,265 |
Total cash, cash equivalents and restricted cash shown in the condensed consolidated statements of cash flows |  | $ | 435,109 |  |  | $ | 416,884 |
Restricted Cash | Restricted Cash Restricted cash primarily represents funds in a controlled account that was established in connection with the Second Amendment of the Company’s Loan and Security Agreement that is described in Note 9. The use of such non-interest-bearing cash is restricted per the terms of the underlying amended loan agreement and is to be used solely for certain research and development expenses directly attributable to the performance of obligations associated with the Navire-BMS License Agreement, which is further described in Note 10. As of March 31, 2023 and December 31, 2022, restricted cash related to this agreement was $25.4 million and $37.8 million, respectively, which is presented as part of “Restricted cash” on the condensed consolidated balance sheets. Additionally, under certain lease agreements and letters of credit, we have pledged cash and cash equivalents as collateral. As of March 31, 2023, restricted cash related to such agreements was $0.1 million and $2.2 million, which is presented as part of “Restricted cash” and “Other assets”, respectively, on the condensed consolidated balance sheets. As of December 31, 2022, restricted cash related to such agreements was $0.1 million and $2.3 million, which is presented as part of “Restricted cash” and “Other assets”, respectively, on the condensed consolidated balance sheets.
Concentration of Credit Risk and Other Risks and Uncertainties | Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and restricted cash. Substantially all of our cash, cash equivalents, marketable securities and restricted cash are held in financial institutions in the United States. Amounts on deposit may at times exceed federally insured limits. Although management currently believes that the financial institutions with whom it does business will be able to fulfill their commitments to the Company, there is no assurance that those institutions will be able to continue to do so. The Company has not experienced any credit losses associated with its balances in such accounts as of March 31, 2023 and December 31, 2022, and for the three months ended March 31, 2023 and 2022. We are subject to certain risks and uncertainties and we believe that changes in any of the following areas could have a material adverse effect on future financial position or results of operations: ability to obtain future financing, regulatory approval and market acceptance of, and reimbursement for, product candidates, performance of third-party contract research organizations and manufacturers upon which we rely, development of sales channels, protection of our intellectual property, litigation or claims against us based on intellectual property, patent, product, regulatory, clinical or other factors, and our ability to attract and retain employees necessary to support our growth. We are dependent on third-party manufacturers to supply products for research and development activities in our programs. In particular, we rely and expect to continue to rely on a small number of manufacturers to supply us with our requirements for the active pharmaceutical ingredients and formulated drugs related to these programs. These programs could be adversely affected by a significant interruption in the supply of active pharmaceutical ingredients and formulated drugs. In March 2020, the World Health Organization declared the outbreak of SARS-CoV-2, the novel strain of coronavirus that causes Coronavirus disease 19 (“COVID-19”), a global pandemic. Since then, healthcare providers and hospitals have focused significant amounts of resources on fighting the virus and its variants, and we have experienced delays in or temporary suspension of the enrollment of patients in our subsidiaries’ ongoing clinical trials. Additionally, we may experience delays in certain ongoing key program activities, including commencement of planned clinical trials, as well as non-clinical experiments and Investigational New Drug Application-enabling good laboratory practice toxicology studies. The exact timing of delays and their overall impact on our business are currently unknown and we are monitoring the COVID-19 pandemic as it continues to evolve. While certain measures have been relaxed in certain parts of the world as increasing numbers of people have received COVID-19 vaccines, others have remained in place with some areas continuing to experience renewed outbreaks and surges in infection rates. The extent to which such measures are removed or new measures are put in place will depend upon how the pandemic evolves, as well as the distribution of available vaccines, the rates at which they are administered and the emergence of new variants of the virus. We are continuing to actively monitor the situation and may take further precautionary and preemptive actions as may be required by federal, state, or local authorities or that we determine are in the best interests of public health and safety and that of our patient community, employees, partners, suppliers, and stockholders. We cannot predict the effects that such actions, or the impact of COVID-19 on global business operations and economic conditions, may have on our business or strategy, including the effects on our ongoing and planned clinical development activities and prospects or on our financial and operating results.
Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the reporting period. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to: • accruals for research and development activities and contingent clinical, development, regulatory, and sales-based milestone payments in our in-licensing agreements and asset acquisitions, • accruals for performance-based milestone compensation arrangements, • determining and allocating the transaction price to performance obligations for transactions accounted for under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers, • the expected recoverability and estimated useful lives of our long-lived assets, and • additional charges as a result of, or that are associated with, any restructuring initiative as well as impairment and related charges. We base our estimates on historical experience and on various other assumptions that we believe are reasonable. Actual results may differ from those estimates or assumptions.
Stock-Based Compensation | We evaluated the exchange of the controlled entities’ outstanding common stock and equity awards for BridgeBio awards as a modification under ASC 718, Share Based Payments. Under ASC 718, a modification is a change in the terms or conditions of a stock-based compensation award. In assessing the accounting treatment, we consider the fair value, vesting conditions and classification as an equity or liability award of the controlled entity equity before the exchange, compared to the BridgeBio equity received as part of the exchange to determine whether modification accounting must be applied. When applying modification accounting, we considered the type of modification to determine the appropriate stock-based compensation cost to be recognized on April 22 and November 18, 2020, (each the “Modification Date”), and subsequent to the Modification Date.
