OCULAR THERAPEUTIX INC

(Amounts in thousands, except share and per share data)

1. Nature of the Business

Ocular Therapeutix, Inc. (the “Company”) was incorporated on September 12, 2006 under the laws of the State of Delaware. The Company is a biopharmaceutical company committed to improving vision in the real world through the development and commercialization of innovative therapies for retinal diseases and other eye conditions. AXPAXLI (axitinib intravitreal implant), the Company’s product candidate for retinal disease, is based on its ELUTYX proprietary bioresorbable hydrogel-based formulation technology. AXPAXLI is currently in Phase 3 clinical trials for wet age-related macular degeneration (“wet AMD”).

The Company also leverages the ELUTYX technology in its commercial product DEXTENZA (dexamethasone insert) 0.4mg, a corticosteroid approved by the U.S. Food and Drug Administration for the treatment of ocular inflammation and pain following ophthalmic surgery and ocular itching associated with allergic conjunctivitis, and in its product candidate PAXTRAVA (travoprost intracameral implant or OTX-TIC), which is currently in a Phase 2 clinical trial for the treatment of open-angle glaucoma or ocular hypertension.

The Company is subject to risks common to companies in the biotechnology industry including, but not limited to, new technological innovations, protection of proprietary technology, dependence on key personnel, dependence on specific programs, compliance with government regulations, regulatory approval and compliance, reimbursement, uncertainty of market acceptance of products and the need to obtain additional financing. Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval, prior to commercialization. Approved products will require significant sales, marketing and distribution support. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval and adequate reimbursement or that any approved products will be commercially viable. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales. The Company operates in an environment of rapidly changing technology and substantial competition from pharmaceutical and biotechnology companies. In addition, the Company is dependent upon the services of its employees and consultants. The Company may not be able to generate significant revenue from sales of any product for several years, if at all. Accordingly, the Company will need to obtain additional capital to finance its operations.

The Company has incurred losses and negative cash flows from operations since its inception, and the Company expects to continue to generate operating losses and negative cash flows from operations in the foreseeable future. As of September 30, 2024, the Company had an accumulated deficit of $842,696. Based on its current operating plan which includes estimates of anticipated cash inflows from product sales and cash outflows from operating expenses and capital expenditures, the Company believes that its existing cash and cash equivalents of $427,220 as of September 30, 2024 will enable it to fund its planned operating expenses, debt service obligations and capital expenditures at least through the next 12 months from the issuance date of these unaudited condensed consolidated financial statements while the Company observes a minimum liquidity covenant of $20,000 in its credit facility (Note 7).

The future viability of the Company is dependent on the Company’s ability to generate cash flows from the sales of the Company’s product candidates, such as AXPAXLI, if and as approved, and the sales of DEXTENZA, and to raise additional capital to finance its operations. The Company will need to finance its operations through public or private securities offerings, debt financings, collaborations, strategic alliances, licensing agreements, royalty agreements, or marketing and distribution agreements. Although the Company has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. If the Company is unable to obtain funding on a timely basis, in sufficient amounts, or at all, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs for product candidates, product portfolio expansion or commercialization efforts, any of which could adversely affect its business prospects, or the Company may be unable to continue operations.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements are consistent with those described in Note 2 - Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“SEC”) on March 11, 2024. The following information updates, and should be read in conjunction with, the significant accounting policies described in Note 2 - Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 11, 2024.

Warrants

The Company accounts for issued warrants, including pre-funded warrants, as either liability or equity. Warrants are considered liabilities if they are mandatorily redeemable and they require settlement in cash or other assets, or a variable number of shares. Contracts that may require settlement for cash are liabilities, regardless of the probability of the occurrence of the triggering event. If warrants do not otherwise require liability classification, the Company assesses whether the warrants are indexed to its common stock. Liability-classified warrants are measured at fair value on the issuance date and at the end of each reporting period. Any change in the fair value of the warrants after the issuance date is recorded in the consolidated statements of operations as a gain or loss. Equity-classified warrants are accounted for at fair value on the issuance date with no changes in fair value recognized after the issuance date.

Use of Estimates

The preparation of these unaudited condensed consolidated financial statements in conformity with GAAP requires 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 these unaudited condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in these unaudited condensed consolidated financial statements include, but are not limited to, the measurement and recognition of reserves for variable consideration related to product sales, revenue recognition related to a collaboration agreement that contains multiple promises, the fair value of derivatives, stock-based compensation, and realizability of net deferred tax assets. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ from the Company’s estimates.

Unaudited Interim Financial Information

The balance sheet at December 31,2023 was derived from the Company’s audited consolidated financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of September 30, 2024 and for the three and nine months ended September 30, 2024 and 2023 have been prepared by the Company, pursuant to the rules and regulations of the SEC for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K for the year ended December 31,2023, filed with the SEC on March 11, 2024. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s financial position as of September 30, 2024, the results of operations for the three and nine months ended September 30, 2024 and 2023, and cash flows for the nine months ended September 30, 2024 and 2023 have been made. The results of operations for the three and nine months ended September 30, 2024 and 2023 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2024.

Recently Issued Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07Segment Reporting - Improvements to Reportable Segment Disclosures. The amendments require disclosure of incremental segment information on an annual and interim basis. The amendments also require companies with a single reportable segment to provide all disclosures required by this amendment and all existing segment disclosures in Accounting Standards Codification Topic 280Segment Reporting. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. The Company does not expect the adoption of the amendments to have a significant impact on its consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09Income Taxes - Improvements to Income Tax Disclosures. The amendments require (i) enhanced disclosures in connection with an entity's effective tax rate reconciliation and (ii) income taxes paid disaggregated by jurisdiction. The amendments are effective for annual periods beginning after December 15, 2024. The Company does not expect the adoption of the amendments to have a significant impact on its consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03Disaggregation of Income Statement Expenses. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses and is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company does not expect the adoption of the amendments to have a significant impact on its consolidated financial statements.

3. Licensing Agreements and Deferred Revenue

Incept License Agreement (in-licensing)

On September 13, 2018, the Company entered into a second amended and restated license agreement with Incept, LLC (“Incept”) to use and develop certain intellectual property (the “Incept License Agreement”). Under the Incept License Agreement, as amended and restated, the Company was granted a worldwide, perpetual, exclusive license to use specific Incept technology to develop and commercialize products that are delivered to or around the human eye for diagnostic, therapeutic or prophylactic purposes relating to ophthalmic diseases or conditions. The Company is obligated to pay low single-digit royalties on net sales of commercial products developed using the licensed technology, commencing with the date of the first commercial sale of such products and until the expiration of the last to expire of the patents covered by the license.

The terms and conditions of the Incept License Agreement are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 11, 2024.

Royalties paid under this agreement related to product sales (the “Incept Royalties”) were $491 and $1,373 for the three and nine months ended September 30, 2024, respectively, and $451 and $1,264 for the three and nine months ended September 30, 2023, respectively. The Incept Royalties have been charged to cost of product revenue.

AffaMed License Agreement (out-licensing)

On October 29, 2020, the Company entered into a license agreement (“AffaMed License Agreement”) with AffaMed Therapeutic Limited (“AffaMed”) for the development and commercialization of the Company’s DEXTENZA product regarding ocular inflammation and pain following cataract surgery and allergic conjunctivitis and for the Company’s PAXTRAVA product candidate (collectively the “AffaMed Licensed Products”) regarding open-angle glaucoma or ocular hypertension, in each case in mainland China, Taiwan, Hong Kong, Macau, South Korea, and the countries of the Association of Southeast Asian Nations. The Company retains development and commercialization rights for the AffaMed Licensed Products in the rest of the world.

Restructuring

On May 29, 2024, the Company’s board of directors approved a strategic reduction in force to eliminate 37 full-time employees of the Company, primarily in research and development and technical operations and representing approximately 13% of the Company’s workforce, as part of an initiative to prioritize Company resources on the clinical development of AXPAXLI for the treatment of wet AMD.

The Company substantially completed the reduction in force and recorded the related restructuring costs, primarily for paid leave for terminated employees, severance, and related costs, in the three months ended June 30, 2024. The accrued restructuring costs remaining at June 30, 2024 were paid in the three months ended September 30, 2024.

A roll-forward of the costs accrued with regard to this restructuring is as follows:

Restructuring costs incurred during the nine months ended September 30, 2024 are included in general and administrative expenses on the consolidated statements of operations and comprehensive loss.

Accrued Expenses

Accrued expenses and other current liabilities consisted of the following:

7. Financial Liabilities

Barings Credit Agreement

On August 2, 2023 (the “Closing Date”), the Company entered into a credit and security agreement (the “Barings Credit Agreement”) with Barings Finance LLC (“Barings”), as administrative agent, and the lenders party thereto, providing for a secured term loan facility for the Company (the “Barings Credit Facility”) in the aggregate principal amount of $82,474 (the “Total Credit Facility Amount”). The Company borrowed the full amount of $82,474 at closing and received proceeds of $77,290, after the application of an original issue discount and fees. Indebtedness under the Barings Credit Facility matures on the earlier to occur of (i) the six-year anniversary of the Closing Date and (ii) the date that is 91 days prior to the maturity date for the Company’s Convertible Notes (as defined below). Indebtedness under the Barings Credit Facility incurs interest based on the Secured Overnight Financing Rate (“SOFR”), subject to aminimum 1.50% floor, plus 6.75%. The Company is obligated to make interest payments on its indebtedness under the Barings Credit Facility on a monthly basis, commencing on the Closing Date; to pay annual administration fees; and to pay, on the maturity date, any principal and accrued interest that remains outstanding as of such date. In addition, the Company is obligated to pay a fee in an amount equal to the Total Credit Facility Amount, which amount shall be reduced by the total amount of interest and principal prepayment fees paid under the Barings Credit Agreement (such fee, the “Barings Royalty Fee”). The Company is required to pay the Barings Royalty Fee in installments to Barings, for the benefit of the lenders, on a quarterly basis in an amount equal to three and one-half percent (3.5%) of the net sales of DEXTENZA occurring during such quarter, subject to the terms, conditions and limitations specified in the Barings Credit Agreement, until the Barings Royalty Fee is paid in full. The Barings Royalty Fee is due and payable upon a change of control of the Company. The Company may, at its option, prepay any or all of the Barings Royalty Fee at any time without penalty. In connection with the Barings Credit Agreement, the Company granted the lenders thereto a first-priority security interest in all assets of the Company, including its intellectual property, subject to certain agreed-upon exceptions. The Barings Credit Agreement includes a negative covenant requiring the Company to maintain a minimum liquidity amount of $20,000. The Barings Credit Agreement also includes customary affirmative and negative covenants.

The Company determined that the embedded obligation to pay the Barings Royalty Fee (the “Barings Royalty Fee Obligation”) is required to be separated from the Barings Credit Facility and accounted for as a freestanding derivative instrument subject to derivative accounting. The allocation of proceeds to the Barings Royalty Fee Obligation resulted in a discount on the Barings Credit Facility. The Company is amortizing the discount to interest expense over the term of the Barings Credit Facility using the effective interest method. Accrued or paid Barings Royalty Fees are included in the change in fair value of derivative liabilities on the consolidated statements of operations and comprehensive loss (Note 9).

A summary of the Barings Credit Facility at September 30, 2024 and December 31, 2023 is as follows:

As of September 30, 2024, the full principal for the Barings Credit Facility of $82,474 was due for repayment in 2029.

Convertible Notes

On March 1, 2019, the Company issued $37,500 of convertible notes, which accrued interest at an annual rate of 6% of their outstanding principal amount which was payable, along with the principal amount, at maturity unless earlier converted, repurchased or redeemed (as amended the “Convertible Notes”). The terms and conditions of the Convertible Notes are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 11, 2024.

The Company has determined that the embedded conversion option was required to be separated from the Convertible Notes and has accounted for the embedded conversion option as a freestanding derivative instrument subject to derivative accounting (the “Conversion Option Derivative Liability”).

On March 28, 2024, the Company issued 5,769,232 shares of its common stock with a total fair value of $52,499 (Note 10) to the holder of the Convertible Notes in connection with the conversion of the principal amount of the Convertible Notes (the “Conversion”) and paid the holder $11,361 for accrued interest. The extinguishment of obligations under the Convertible Notes and the resulting derecognition of the principal of the Convertible Notes ($37,500), the unamortized discount ($27,950), and the Conversion Option Derivative Liability ($15,000), resulted in a net loss of $27,950, which was charged to losses on extinguishment of debt on the unaudited condensed consolidated statements of operations and comprehensive loss for the nine months ended September 30, 2024.

Concurrently with entering into the Barings Credit Agreement, on August 2, 2023, the Company and the holders of the Convertible Notes extended the maturity of the Convertible Notes, which would otherwise have matured on March 1, 2026, to a date 91 days following the maturity of the indebtedness under the Barings Credit Facility, unless earlier converted, repurchased or redeemed (the “Amendment”). The Company accounted for the Amendment as an extinguishment of debt in accordance with the guidance in Accounting Standards Codification Topic 470-50Debt (“ASC 470-50”). Details of the accounting for the Amendment are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 11, 2024. Application of ASC 470-50 resulted in a gain on extinguishment of debt of $14,907, which was charged to gains and losses on extinguishment of debt, net, on the consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2023.

MidCap Credit Agreement

The Company entered into a credit and security agreement in 2014 (as amended, the “MidCap Credit Agreement”) establishing a credit facility (the “MidCap Credit Facility”). The terms and conditions of the MidCap Credit Agreement and the MidCap Credit Facility are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 11, 2024. In connection with entering into the Barings Credit Facility, in August 2023 the Company paid MidCap Financial Trust, as administrative agent, and its other lenders an aggregate of

$26,157 in satisfaction of the Company’s obligations under the MidCap Credit Facility. In connection with its satisfaction of its obligations, the Company extinguished the MidCap Credit Facility, and all liens and security interests securing the indebtedness under the MidCap Credit Agreement were released. The extinguishment of the MidCap Credit Facility resulted in a loss of $717, which was charged to gains and losses on extinguishment of debt, net, on the consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2023.

In March 2023, the Company requested, and received, a protective advance of $2,000 under the MidCap Credit Agreement as a short-term bridge loan in response to the closure of Silicon Valley Bank by the California Department of Financial Protection and Innovation. This protective advance was deemed a credit extension. The Company repaid the full principal amount of $2,000 in March 2023.

8. Derivative Liability

Barings Credit Agreement

The Barings Credit Agreement (Note 7) contains the embedded Barings Royalty Fee Obligation that meets the criteria to be bifurcated and accounted for separately from the Barings Credit Facility (the “Royalty Fee Derivative Liability”). The Royalty Fee Derivative Liability was recorded at fair value upon the entering into the Barings Credit Facility and is subsequently remeasured to fair value at each reporting period. The Royalty Fee Derivative Liability was initially valued and is remeasured using a “with-and-without” method. The “with-and-without” methodology involves valuing the whole instrument on an as-is basis with the embedded Barings Royalty Fee Obligation and then valuing the instrument without the embedded Barings Royalty Fee Obligation. Royalty payments are estimated using a Monte Carlo simulation. Refer to Note 9 for details regarding the determination of fair value.

A roll-forward of the Royalty Fee Derivative Liability is as follows:

Convertible Notes

The Convertible Notes (Note 7), which were extinguished in March 2024, contained the Conversion Option Derivative Liability, an embedded conversion option that meets the criteria to be bifurcated and accounted for separately from the Convertible Notes. The Conversion Option Derivative Liability was recorded at fair value upon the issuance of the Convertible Notes and was subsequently remeasured to fair value at each reporting period. The Conversion Option Derivative Liability was initially valued and was subsequently remeasured using a “with-and-without” method. The “with-and-without” methodology involves valuing the whole instrument on an as-is basis with the embedded conversion option and then valuing the instrument without the embedded conversion option. The difference between the entire instrument with the embedded conversion option compared to the instrument without the embedded conversion option is the fair value of the derivative, recorded as the Conversion Option Derivative Liability. Refer to Note 9 for details regarding the determination of fair value.

A roll-forward of the Conversion Option Derivative Liability is as follows:

9. Risks and Fair Value

Concentration of Credit Risk and of Significant Suppliers and Customers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company has its cash and cash equivalents balances attwo accredited financial institutions, in amounts that exceed federally insured limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company is dependent on a small number of third-party manufacturers to supply products for research and development activities in its preclinical and clinical programs and for sales of its products. The Company’s development programs as well as revenue from future product sales could be adversely affected by a significant interruption in the supply of any of the components of these products.

Three specialty distributor customers accounted for the following percentages of the Company’s total revenue:

Three specialty distributor customers accounted for the following percentages of the Company’s accounts receivable, net:

Change in Fair Value of Derivative Liabilities

Other income (expenses) from the change in the fair values of derivative liabilities as presented on the Company’s consolidated statements of operations and comprehensive loss includes the following:

Fair Value of Financial Assets and Liabilities

The following tables present information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2024 and December 31, 2023 and indicate the level of the fair value hierarchy utilized to determine such fair value:

Barings Credit Agreement and Royalty Fee Derivative Liability

At September 30, 2024, the Barings Credit Facility, net of the Royalty Fee Derivative Liability, was carried at amortized cost totaling $68,525, comprised of the $67,815 non-current liability (Note 7) and $710 accrued interest (Note 6). The estimated fair value of the Barings Credit Facility, without the Royalty Fee Derivative Liability, was $74,009 at September 30, 2024. At December 31, 2023, the Barings Credit Facility, net of the Royalty Fee Derivative Liability, was carried at amortized cost totaling $66,590 comprised of the $65,787 non-current liability (Note 7) and $803 accrued interest (Note 6). The estimated fair value of the Barings Credit Facility, without the Royalty Fee Derivative Liability, was $72,295 at December 31, 2023.

The fair value of the Royalty Fee Derivative Liability is estimated using a Monte Carlo simulation. The use of this approach requires the use of Level 3 unobservable inputs. The main inputs when determining the fair value of the Royalty Fee Derivative Liability are the amount and timing of the expected future revenue of the Company, the estimated volatility of these revenues, and the discount rate corresponding to the risk of revenue. The estimated fair value presented is not necessarily indicative of an amount that could be realized in a current market exchange. The use of alternative inputs and estimation methodologies could have a material effect on these estimates of fair value.

The main inputs to valuing the Royalty Fee Derivative Liability are as follows:

Convertible Notes and Conversion Option Derivative Liability

At December 31, 2023, the Convertible Notes, net of the Conversion Option Derivative Liability, were carried at amortized cost totaling $20,024, comprised of the $9,138 non-current liability (Note 7) and $10,886 accrued interest (Note 6).

The fair value of the Convertible Notes with and without the conversion option as of December 31, 2023 was estimated using a binomial lattice approach. The use of this approach required the use of Level 3 unobservable inputs. The main input when determining the fair value of the Convertible Notes was the bond yield that pertained to the host instrument without the conversion option. The significant assumption used in determining the bond yield was the market yield movements of a comparable instrument issued as of the valuation date, which was assessed and updated each period. The main input when determining the fair value for disclosure purposes was the bond yield which was updated each period to reflect the yield of a comparable instrument issued as of the valuation date. The fair value of the Conversion Option Derivative Liability immediately before the Conversion was determined based on the intrinsic value of the separated conversion option.

10. Equity

In June 2024, the Company adopted an amended and restated certificate of incorporation increasing the number of its authorized shares of its common stock by 200,000,000 shares to 400,000,000 shares.

On February 21, 2024, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain institutional accredited investors (the “Investors”), pursuant to which the Company issued and sold to the Investors in a private placement an aggregate of 32,413,560 shares of the Company’s common stock, par value $0.0001 per share (the “Shares”), at a price of $7.52 per share, and, to certain Investors in lieu of Shares, pre-funded warrants to purchase 10,805,957 shares of the Company’s common stock (the “Pre-Funded Warrants”), at a price of $7.519 per Pre-Funded Warrant (the “2024 Private Placement”). Each Pre-Funded Warrant issued in the 2024 Private Placement has an exercise price of $0.001 per share, is currently exercisable and will remain exercisable until the Pre-Funded Warrant is exercised in full. The 2024 Private Placement closed on February 26, 2024. The Company received total net proceeds from the 2024 Private Placement of approximately $316,353 after deducting placement agent fees and offering expenses. The Company accounts for the Pre-Funded Warrants as a component of permanent equity. In connection with entering into the Securities Purchase Agreement, also on February 21, 2024, the Company entered into a registration rights agreement with the Investors, pursuant to which the Company agreed to register for resale the Shares and the shares of the Company’s common stock issuable upon exercise of the Pre-Funded Warrants (together with the Shares, the “Registrable Securities”). The Company filed a registration statement regarding the Registrable Securities on Form S-3 with the SEC on March 25, 2024.

On March 28, 2024, the Company issued 5,769,232 shares of its common stock to the holder of the Convertible Notes in connection with the Conversion. The newly issued shares of common stock were valued at fair value, being the closing price of the Company’s common stock on that day, and resulted in an increase in additional paid-in capital of $52,499.

On August 9, 2021, the Company and Jefferies LLC (“Jefferies”) entered into an Open Market Sale Agreement (the “2021 Sales Agreement”) under which the Company may offer and sell shares of its common stock having an aggregate offering price of up to $100,000 from time to time through Jefferies, acting as agent. The Company didnot offer or sell shares of its common stock under the 2021 Sales Agreement during the three and nine months ended September 30, 2024. During the three and nine months ended September 30, 2023, the Company sold 144,718 and 1,514,926 shares of common stock, respectively, under the 2021 Sales Agreement, resulting in gross proceeds to the Company of $734 and $9,897, and net proceeds, after accounting for issuance costs, of $708 and $9,532, respectively.

11. Stock-Based Awards
