CARIBOU BIOSCIENCES, INC. AND ITS SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

(Unaudited)

 

1. Description of the Business, Organization, and Liquidity

 

Business and Organization

 

Caribou Biosciences, Inc. (the “Company” or “we”) is a clinical-stage CRISPR genome-editing biopharmaceutical company dedicated to developing innovative, transformative therapies for patients with devastating diseases. CRISPR is an acronym for Clustered Regularly Interspaced Short Palindromic Repeats. Our novel CRISPR platform, CRISPR hybrid RNA-DNA (“chRDNA,” pronounced “chardonnay”), enables high genome-editing precision to develop cell therapies that are specifically engineered to target cancer and are armored for enhanced persistence. We are advancing a pipeline of allogeneic, or off-the-shelf, chimeric antigen receptor (“CAR”)-T (“CAR-T”) and CAR-natural killer (“CAR-NK”) cell therapies for the treatment of patients with hematologic malignancies and solid tumors.

 

We incorporated in October 2011 as a Delaware corporation and are headquartered in Berkeley, California. We have four wholly owned subsidiaries: Antler Holdco, LLC, incorporated in Delaware in April 2019; Microbe Holdco, LLC, incorporated in Delaware in June 2020; Arboreal Holdco, LLC, incorporated in Delaware in November 2020; and Biloba Holdco, LLC, incorporated in Delaware in April 2021. Our wholly owned subsidiaries hold interests in our equity investments and do not have operating activities.

 

Liquidity

 

We have incurred net losses and negative cash flows from operations since our inception and we had an accumulated deficit of $116.9 million as of March 31, 2022. During the three months ended March 31, 2022, we incurred a net loss of $19.1 million and used $21.7 million of cash in operating activities. We expect to continue to incur substantial losses, and our ability to achieve and sustain profitability will depend on the successful development, approval, and commercialization of our product candidates and on our achievement of sufficient revenue to support our cost structure. We may never achieve profitability and, unless and until we do, we will need to continue to raise additional capital. Our management expects that existing cash, cash equivalents, and marketable securities of $390.8 million as of March 31, 2022, will be sufficient to fund our current operating plan for at least the next 12 months from the date of issuance of our condensed consolidated financial statements.

2. Summary of Significant Accounting Policies

 

There have been no changes to the significant accounting policies disclosed in Note 2 to the annual consolidated financial statements for the year ended December 31, 2021 included in our Annual Report on Form 10-K (“Form 10-K”), other than changes to our leasing policy described below in connection with the adoption of the guidance under the Accounting Standards Codification (“ASC”) 842, Leases.

 

Basis of Presentation and Principles of Consolidation

 

The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of Caribou Biosciences, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated in consolidation.

 

Use of Estimates

 

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities; the disclosure of contingent assets and liabilities at the date of our condensed consolidated financial statements; and the reported amounts of revenue, income, and expenses during the applicable reporting period. On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, common stock valuation, stock-based compensation expense, accrued expenses related to research and development activities, valuation of the Memorial Sloan Kettering Cancer Center (“MSKCC”) success payments liability, and income taxes. Our management bases its estimates on historical experience and on various other assumptions that they believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from those estimates.

6


 

 

Segments

 

We operate and manage our business as one reportable and operating segment, which is the business of developing a pipeline of allogeneic CAR-T and CAR-NK cell therapies. Our president and chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for allocating resources and evaluating financial performance. All long-lived assets are maintained in the United States.

 

Concentrations of Credit Risk and Other Uncertainties

 

Financial instruments that potentially subject us to concentration of credit risk consist of cash and cash equivalents, accounts receivable, contract assets, other receivables, and investments in marketable securities and equity securities. Substantially all of our cash and cash equivalents are deposited in accounts at two financial institutions, and account balances may at times exceed federally insured limits. We mitigate the risks by investing in high-grade instruments, limiting our exposure to one issuer, and we monitor the ongoing creditworthiness of the financial institutions and issuers. We believe these financial institutions to be of high credit quality.
