Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Business Activity Shoulder Innovations, Inc. (the “Company”) is principally involved in developing next generation shoulder replacement implants, utilizing contract manufacturing partners, and distributing them nationwide for surgeries through a network of employed and contracted sales representatives. The Company is headquartered in Grand Rapids, Michigan and markets and sells its products throughout the United States. Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. Certain information and note disclosures included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited condensed financial statements should be read in conjunction with the audited annual financial statements for the year ended December 31, 2024 included in the Company’s final prospectus, dated July 30, 2025, filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”) on August 1, 2025 (the “Prospectus”). There have been no material changes in our significant accounting policies as described in our audited annual financial statements for the year ended December 31, 2024. In the opinion of management, these unaudited condensed financial statements reflect all adjustments, including those of a normal and recurring nature, which are necessary for a fair presentation of the results for the interim period presented. Reverse Stock Split On July 23, 2025, the Company amended its amended and restated certificate of incorporation to effect a reverse stock split of shares of the Company’s common stock on a 1-for-19.08 basis (the “Reverse Stock Split”). The common stock warrants and options to purchase common stock were subsequently adjusted as a result of the Reverse Stock Split. All impacted share and per-share information included in these unaudited condensed financial statements and notes thereto have been retroactively adjusted to give effect to the Reverse Stock Split. Initial Public Offering On August 1, 2025, the Company closed its initial public offering (“IPO”), and issued 5,000,000 shares of common stock at public offering price of $15.00 per share. The Company received net proceeds of approximately $64,212, after deducting underwriting discounts and commissions and offering expenses. Immediately prior to the closing of the IPO, all outstanding shares of convertible preferred stock and $40,000 in aggregate principal amount of convertible notes converted into 15,176,862 shares of common stock. In connection with the closing of the IPO, on August 1, 2025, the Company amended and restated its certificate of incorporation to authorize the issuance of up to 730,000,000 shares of common stock, par value $0.001 per share and 20,000,000 shares of preferred stock, par value $0.001 per share. New Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) ("ASC 740"). The update requires all public business entities on an annual basis to (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold and an explanation, if not otherwise evident, of the individual reconciling items disclosed, such as the nature, effect, and underlying causes of the reconciling items and the judgment used in categorizing the reconciling items. In addition, the update requires certain new disclosures of the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid is equal to or greater than five percent of total income taxes paid (net of refunds received). Other new disclosures required include income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. The new guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments are to be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact of the new standard on its financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses requires additional, disaggregated disclosure around certain income statement expense line items. This ASU mandates that entities, at each interim and annual period, disclose the amounts of (a) inventory purchases, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depletion, depreciation, and amortization for oil and gas activities included within each relevant expense caption presented on the income statement within continuing operations. Entities are also required to (1) combine certain disclosures already mandated under GAAP with these new requirements, (2) provide qualitative descriptions of expenses that are not disaggregated quantitatively, and (3) disclose total selling expenses and, annually, the definition of selling expenses. The guidance is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact of adopting this new guidance on its financial statements and related disclosures.
