Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2023 has been derived from the audited consolidated financial statements at that date but does not include all of the information required by U.S. GAAP for complete financial statements. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments that are necessary for a fair statement of the Company’s consolidated financial information. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other interim period or for any other future year.

The accompanying condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes thereto for the year ended December 31, 2023 contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2024 (the “2023 Annual Report”).

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant accounting estimates and management judgments reflected in the condensed consolidated financial statements primarily includes the fair value of performance-based restricted stock unit awards. Estimates are based on historical experience, where applicable and other assumptions believed to be reasonable by the management. Actual results could differ from those estimates.

Change in accounting estimate

During the first quarter of 2024, the Company reassessed the useful life of its instrument trays based on a comprehensive evaluation of usage trends and its estimate on the average life of instruments before loss or damage that requires disposal. As a result of this review, the Company determined that extending the useful life of its instrument trays would more accurately reflect its anticipated future economic benefits. Effective January 1, 2024, the Company changed its estimates of the useful lives of instrument trays from three to five years. The effect of this change in estimate reduced depreciation expense by $0.5 million, resulting in a decrease in net loss of $0.5 million and basic and diluted earnings per share by $0.01 for the three months ended June 30, 2024. The effect of this change in estimate reduced depreciation expense by $1.0 million, resulting in a decrease in loss from operations and net loss of $1.0 million and basic and diluted earnings per share by $0.03 for the six months ended June 30, 2024.

Significant Accounting Policies

The Company’s significant accounting policies are disclosed in the 2023 Annual Report. There have been no material changes to these accounting policies.

Segments

The Company's chief operating decision makers are the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”). The CEO and the CFO review financial information presented on a consolidated basis, accompanied by information about revenue by geographic region, for purposes of evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, the Company has determined that it has a single reportable and operating segment structure.

The Company derives substantially all of its revenue from sales to customers in the U.S. Revenue by geography is based on billing address of the customer. International revenue accounted for less than 10% of the total revenue during the periods presented. Long-lived assets held outside the U.S. are immaterial. The following table summarizes the Company's revenue by geography:

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 requires companies with a single reportable segment to provide all existing segment disclosures, as well as requires incremental segment information to be disclosed. The guidance is effective for fiscal years beginning after December 15, 2023 on a retrospective basis, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the guidance to determine the impact on its disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 requires public business entities to disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate (the rate reconciliation) for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a specified threshold. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, and for interim periods for fiscal years beginning after December 15, 2025. The Company is currently evaluating the impacts of ASU 2023-09 on its disclosures.
