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 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, 2021 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’ equity (deficit) and our cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other future annual or interim periods.
Reclassifications	Reclassifications Certain reclassifications have been made to the condensed consolidated statement of cash flows for the six months ended June 30, 2021 to conform to the current year’s presentation. These reclassifications had no net effect on cash flows from operating, financing and investing activities as previously reported.
Restricted Cash	Restricted Cash Our restricted cash balance relates to cash and cash equivalents that we have pledged as collateral under certain lease agreements and letters of credit.
Collaborative Arrangements	Collaborative Arrangements We enter into collaboration arrangements with partners, under which we may grant licenses to further develop, manufacture and commercialize one of our drug compounds and or/products. We may also perform research, development, manufacturing, commercialization, and supply activities under our collaboration agreements. Consideration under these arrangements may include, upfront payments, development and regulatory milestones, expense reimbursements, royalties based on net sales of commercial products, and commercial sales milestone payments. When we enter into collaboration agreements, we assess whether the arrangements fall within the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements (“ASC 808”) based on whether the arrangements involve joint operating activities and whether both parties have active participation in the arrangement and are exposed to significant risks and rewards. To the extent that the arrangement falls within the scope of ASC 808, we assess whether the payments between us and our partner fall within the scope of other accounting literature. If we conclude that payments from the partner to us represent consideration from a customer, such as license fees, contract manufacturing, and research and development activities, we account for those payments within the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”). However, if we conclude that our partner is not a customer for certain activities and associated payments, such as for certain collaborative research, development, manufacturing, and commercial activities, we record such payments as a reduction of research and development expense or selling, general and administrative expense, based on where we present the underlying expense. Additionally, if we reimburse our collaboration partners for these activities, we record such reimbursements as research and development expense or selling, general and administrative expense, depending upon the nature of the underlying expense. If our collaborative arrangement provides for the sharing of profits and losses with our partner for commercialization activities, the treatment of our share in the profit-sharing structure depends on who the selling party is. If we are the selling party and the deemed principal, we record our collaboration partner’s share of profits as an addition to selling, general and administrative expenses and our collaboration partner’s share of loss as a reduction in selling, general and administrative expenses. If our partner is the selling party and the deemed principal, we record our share of profits as collaboration revenue and our share of losses as an addition to selling, general and administrative expenses.
Revenue Recognition	Revenue Recognition For elements or transactions that we determine should be accounted for under ASC 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy our performance obligation. We apply the five-step model to contracts when it is probable that we will collect the consideration to which we are entitled in exchange for the goods or services we transfer to the customer. At inception of the arrangement, we assess the promised goods or services to identify the performance obligations within the contract. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation, on a relative standalone selling price basis, when (or as) the performance obligation is satisfied, either at a point in time or over time. If the performance obligation is satisfied over time, we recognize revenue based on the use of an output or input method. As part of the accounting for these arrangements, we develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. These key assumptions may include forecasted revenue or costs, development timelines, discount rates and probabilities of clinical and regulatory success. License Grant: For arrangements that include a grant of a license to our intellectual property, we consider whether the license grant is distinct from the other performance obligations included in the arrangement. Generally, we would conclude that the license is distinct if the customer is able to benefit from the license with the resources available to it. For licenses that are distinct, we recognize revenues from nonrefundable, upfront license fees and other consideration allocated to the license when the license term has begun and we have provided all necessary information regarding the underlying intellectual property to the customer, which generally occurs at or near the inception of the arrangement. For licenses that are bundled with other promises, we determine whether the combined performance obligation is satisfied over time or at a point in time. If the combined performance obligation is satisfied over time, we use judgment in determining the appropriate method of measuring progress for purposes of recognizing revenue from the up-front license fees. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition. Development and Regulatory Milestone Payments: At the inception of each arrangement that includes development and regulatory milestone payments, we evaluate whether the milestones are considered probable of being achieved and estimate the amount to be included in the transaction price using the most likely amount method. We generally include these milestone payments when they are achieved because there is considerable uncertainty in the research and development processes that trigger these payments under our agreements. Similarly, we include approval milestone payments in the transaction price once the product is approved by the applicable regulatory agency. At the end of each subsequent reporting period, we re-evaluate the probability of achieving such development and regulatory milestones and any related constraint, and if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis. Sales-based Milestone Payments and Royalties: For arrangements that include sales-based royalties, including milestone payments based on the volume of sales, we will determine whether the license is deemed to be the predominant item to which the royalties or sales-based milestones relate and if such is the case, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Product Supply Services: Arrangements that include a promise for the future supply of drug product for either clinical development or commercial supply at the licensee’s discretion are generally considered as options. We will assess if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations and recognized when the future goods or services related to the option are provided or the option expires. Research and Development Services: For arrangements that include research and development services, we will recognize revenue over time using an input method, representing the transfer of goods or services as we perform activities over the term of the agreement.
Sales of Nonfinancial Assets	Sales of Nonfinancial Assets We generally account for sales of nonfinancial assets that are outside the scope of our ordinary activities under ASC 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (“ASC 610-20”). Pursuant to ASC 610-20, we apply the guidance in ASC 606 to determine if a contract exists, identify the distinct nonfinancial assets, and determine when control transfers and, therefore, when to derecognize the nonfinancial asset. Additionally, we apply the measurement principles of ASC 606 to determine the amount of consideration, if any, to include in the calculation of the gain or loss for the nonfinancial asset.
Restructuring, Impairment and Related Charges	Restructuring, Impairment and Related Charges Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances, including restructuring and exit activities, indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount of an asset group to the future net undiscounted cash flows that the assets are expected to generate. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. Costs related to contracts without future benefit or contract termination are recognized at the earlier of the contract termination or the cease-use dates. Employee severance costs are generally recognized when payments are probable and amounts are reasonably estimable. Other exit-related costs are recognized as incurred.
Risks and Uncertainties	Risks and Uncertainties 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 ongoing 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 ASC 606, • 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. We base our estimates on historical experience and on various other assumptions that are believed to be 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.

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 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, 2021 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’ equity (deficit) and our cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other future annual or interim periods.

Reclassifications

Certain reclassifications have been made to the condensed consolidated statement of cash flows for the six months ended June 30, 2021 to conform to the current year’s presentation. These reclassifications had no net effect on cash flows from operating, financing and investing activities as previously reported.

Restricted Cash

Our restricted cash balance relates to cash and cash equivalents that we have pledged as collateral under certain lease agreements and letters of credit.

Collaborative Arrangements

We enter into collaboration arrangements with partners, under which we may grant licenses to further develop, manufacture and commercialize one of our drug compounds and or/products. We may also perform research, development, manufacturing, commercialization, and supply activities under our collaboration agreements. Consideration under these arrangements may include, upfront payments, development and regulatory milestones, expense reimbursements, royalties based on net sales of commercial products, and commercial sales milestone payments.

When we enter into collaboration agreements, we assess whether the arrangements fall within the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements (“ASC 808”) based on whether the arrangements involve joint operating activities and whether both parties have active participation in the arrangement and are exposed to significant risks and rewards. To the extent that the arrangement falls within the scope of ASC 808, we assess whether the payments between us and our partner fall within the scope of other accounting literature. If we conclude that payments from the partner to us represent consideration from a customer, such as license fees, contract manufacturing, and research and development activities, we account for those payments within the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”). However, if we conclude that our partner is not a customer for certain activities and associated payments, such as for certain collaborative research, development, manufacturing, and commercial activities, we record such payments as a reduction of research and development expense or selling, general and administrative expense, based on where we present the underlying expense. Additionally, if we reimburse our collaboration partners for these activities, we record such reimbursements as research and development expense or selling, general and administrative expense, depending upon the nature of the underlying expense.

If our collaborative arrangement provides for the sharing of profits and losses with our partner for commercialization activities, the treatment of our share in the profit-sharing structure depends on who the selling party is. If we are the selling party and the deemed principal, we record our collaboration partner’s share of profits as an addition to selling, general and administrative expenses and our collaboration partner’s share of loss as a reduction in selling, general and administrative expenses. If our partner is the selling party and the deemed principal, we record our share of profits as collaboration revenue and our share of losses as an addition to selling, general and administrative expenses.

Revenue Recognition

For elements or transactions that we determine should be accounted for under ASC 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy our performance obligation. We apply the five-step model to contracts when it is probable that we will collect the consideration to which we are entitled in exchange for the goods or services we transfer to the customer.

At inception of the arrangement, we assess the promised goods or services to identify the performance obligations within the contract. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation, on a relative standalone selling price basis, when (or as) the performance obligation is satisfied, either at a point in time or over time. If the performance obligation is satisfied over time, we recognize revenue based on the use of an output or input method. As part of the accounting for these arrangements, we develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. These key assumptions may include forecasted revenue or costs, development timelines, discount rates and probabilities of clinical and regulatory success.

License Grant: For arrangements that include a grant of a license to our intellectual property, we consider whether the license grant is distinct from the other performance obligations included in the arrangement. Generally, we would conclude that the license is distinct if the customer is able to benefit from the license with the resources available to it. For licenses that are distinct, we recognize revenues from nonrefundable, upfront license fees and other consideration allocated to the license when the license term has begun and we have provided all necessary information regarding the underlying intellectual property to the customer, which generally occurs at or near the inception of the arrangement. For licenses that are bundled with other promises, we determine whether the combined performance obligation is satisfied over time or at a point in time. If the combined performance obligation is satisfied over time, we use judgment in determining the appropriate method of measuring progress for purposes of recognizing revenue from the up-front license fees. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Development and Regulatory Milestone Payments: At the inception of each arrangement that includes development and regulatory milestone payments, we evaluate whether the milestones are considered probable of being achieved and estimate the amount to be included in the transaction price using the most likely amount method. We generally include these milestone payments when they are achieved because there is considerable uncertainty in the research and development processes that trigger these payments under our agreements. Similarly, we include approval milestone payments in the transaction price once the product is approved by the applicable regulatory agency. At the end of each subsequent reporting period, we re-evaluate the probability of achieving such development and regulatory milestones and any related constraint, and if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis.

Sales-based Milestone Payments and Royalties: For arrangements that include sales-based royalties, including milestone payments based on the volume of sales, we will determine whether the license is deemed to be the predominant item to which the royalties or sales-based milestones relate and if such is the case, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Product Supply Services: Arrangements that include a promise for the future supply of drug product for either clinical development or commercial supply at the licensee’s discretion are generally considered as options. We will assess if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations and recognized when the future goods or services related to the option are provided or the option expires.

Research and Development Services: For arrangements that include research and development services, we will recognize revenue over time using an input method, representing the transfer of goods or services as we perform activities over the term of the agreement.

Sales of Nonfinancial Assets

We generally account for sales of nonfinancial assets that are outside the scope of our ordinary activities under ASC 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (“ASC 610-20”). Pursuant to ASC 610-20, we apply the guidance in ASC 606 to determine if a contract exists, identify the distinct nonfinancial assets, and determine when control transfers and, therefore, when to derecognize the nonfinancial asset. Additionally, we apply the measurement principles of ASC 606 to determine the amount of consideration, if any, to include in the calculation of the gain or loss for the nonfinancial asset.

Restructuring, Impairment and Related Charges

Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances, including restructuring and exit activities, indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount of an asset group to the future net undiscounted cash flows that the assets are expected to generate. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset group exceeds the fair value of the asset group.

Costs related to contracts without future benefit or contract termination are recognized at the earlier of the contract termination or the cease-use dates. Employee severance costs are generally recognized when payments are probable and amounts are reasonably estimable. Other exit-related costs are recognized as incurred.

Risks and Uncertainties

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 ongoing 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

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 ASC 606,

•

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.

We base our estimates on historical experience and on various other assumptions that are believed to be 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.
