Note 10. Related Parties

From time to time, the Company will enter into an agreement with a related party in the ordinary course of its business. These agreements are ratified by the Board or a committee thereof pursuant to its related party transaction policy.

Viscient Biosciences (“Viscient”) is an entity for which Keith Murphy, the Company’s Executive Chairman, serves as the Chief Executive Officer and President. Dr. Jeffrey Miner, the Company’s former Chief Scientific Officer, is also the Chief Scientific Officer of Viscient, and Thomas Jurgensen, the Company’s former General Counsel, previously served as outside legal counsel to Viscient through his law firm, Optima Law Group, APC.

On December 28, 2020, the Company entered into an intercompany agreement (the “Intercompany Agreement”) with Viscient and Organovo, Inc., the Company’s wholly-owned subsidiary, which included an asset purchase agreement for certain lab equipment. Pursuant to the Intercompany Agreement, the Company agreed to provide Viscient certain services related to 3D bioprinting technology, which include, but are not limited to, histology services, cell isolation, and proliferation of cells and Viscient agreed to provide the Company certain services related to 3D bioprinting technology, including bioprinter training, bioprinting services, and qPCR assays, in each case on payment terms specified in the Intercompany Agreement and as may be further determined by the parties. In addition, the Company and Viscient each agreed to share certain facilities and equipment and, subject to further agreement, to each make certain employees available for specified projects for the other party at prices to be determined in good faith by the parties. The Company evaluated the accounting for the Intercompany Agreement and concluded that any services provided by Viscient to the Company will be expensed as incurred, and any compensation for services provided by the Company to Viscient will be considered a reduction of personnel related expenses. Any services provided to Viscient do not fall under Topic 606 as the Intercompany Agreement is not a contract with a customer. For the three and nine months ended December 31, 2023 and 2022, the Company incurred no consulting expenses from Viscient. Additionally, for the three and nine months ended December 31, 2023, the Company provided approximately $3,000 and $13,000 of histology services to Viscient, respectively, and $17,000 and $44,000 for the three and nine months ended December 31, 2022, respectively.

Commitments and Contingencies

Note 7. Commitments and Contingencies

Legal Matters

In addition to commitments and obligations in the ordinary course of business, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business.

The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability.

The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with any claims or legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of such an outcome to be remote, if one or more legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected.

Equity [Abstract]

Stockholders' Equity

Note 5. Stockholders’ Equity

Preferred Stock

The Company is authorized to issue 25,000,000 shares of preferred stock. There are no shares of preferred stock currently outstanding, and the Company has no current plans to issue shares of preferred stock.

Common Stock

In March 2021, the Company's Board of Directors ("Board") approved the 2021 Inducement Equity Incentive Plan ("Inducement Plan"). The Inducement Plan authorized the issuance of up to 750,000 shares of common stock for awards of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, RSUs, performance units, performance shares, and other stock or cash awards. The only persons eligible to receive grants under the Inducement Plan are individuals who satisfy the standards for inducement grants under Nasdaq guidance. The Company also committed to reducing the aggregate number of shares of its common stock issuable pursuant to the Inducement Plan from 750,000 shares to 51,000 shares (which includes 50,000 shares of its common stock issuable pursuant to an outstanding option to purchase common stock with an exercise price of $2.75 per share, leaving only 1,000 shares available for future issuance under the Inducement Plan) and the share reserve was reduced accordingly effective October 12, 2022. As of December 31, 2023, there were 1,000 shares available for future grant under the Inducement Plan.

On October 12, 2022, the Company's stockholders and the Board approved the 2022 Equity Incentive Plan ("2022 Plan"), and it became effective on that date. The 2022 Plan replaced the Amended and Restated 2012 Equity Incentive Plan ("2012 Plan") on the effective date. Upon the effective date, the Company ceased granting awards under the 2012 Plan and any shares remaining available for future issuance under the 2012 Plan were cancelled and are no longer available for future issuance. The 2012 Plan continues to govern awards previously granted under it. At the time the Board approved the 2022 Plan, an aggregate of 1,363,000 shares of the Company’s common stock was initially reserved for issuance under the 2022 Plan. The Company committed to reducing the 2022 Plan share reserve by the number of shares that were granted under the 2012 Plan and the Inducement Plan between July 25, 2022 and October 12, 2022. From July 25, 2022 to October 12, 2022, the Company issued 126,262 shares of its common stock under the 2012 Plan. As a result, the number of shares initially reserved for future issuance under the 2022 Plan was 1,236,738 shares of common stock.

The Company previously had an effective shelf registration statement on Form S-3 (File No. 333-222929), declared effective by the SEC on February 22, 2018 (the “2018 Shelf”), which registered $100.0 million of common stock, preferred stock, warrants and units, or any combination of the foregoing, that expired on February 22, 2021. On January 19, 2021, the Company filed a shelf registration statement on Form S-3 (File No. 333-252224) to register $150.0 million of the Company’s common stock, preferred stock, debt securities, warrants and units, or any combination of the foregoing (the “2021 Shelf”). The 2021 Shelf was declared effective by the SEC on January 29, 2021 and replaced the 2018 Shelf at that time. On January 26, 2024, the Company filed a new shelf registration statement on Form S-3 (File No. 333-276722) to register $150.0 million of the Company’s common stock, preferred stock, debt securities, warrants and units, or any combination of the foregoing (the “2024 Shelf”). The 2024 Shelf has not yet been declared effective by the SEC.

On March 16, 2018, the Company entered into a Sales Agreement (“Sales Agreement”) with H.C. Wainwright & Co., LLC and Jones Trading Institutional Services LLC (each an “Agent” and together, the “Agents”). On January 29, 2021, the Company filed a prospectus supplement to the 2021 Shelf (the “2021 ATM Prospectus Supplement”), pursuant to which the Company may offer and sell, from time to time, through the Agents, shares of its common stock in ATM sales transactions having an aggregate offering price of up to $50.0 million. Any shares offered and sold will be issued pursuant to the 2021 Shelf until it is replaced by the 2024 Shelf. During each of the three and nine months ended December 31, 2023, the Company issued 934,621 shares of common stock in ATM offerings under the 2021 ATM Prospectus Supplement. As of December 31, 2023, the Company had sold an aggregate of 2,515,483 shares of common stock in ATM offerings, with gross proceeds of approximately $22.9 million. As of December 31, 2023, there was approximately $100.0 million available for future offerings under the 2021 Shelf (excluding amounts available but not yet issued under the ATM Prospectus Supplement), and approximately $27.1 million available for future offerings through the Company’s ATM program under the 2021 ATM Prospectus Supplement. On January 26, 2024, the Company filed a prospectus to the 2024 Shelf (the “2024 ATM Prospectus”), pursuant to which the Company may offer and sell, from time to time, through the Agents, shares of its common stock in ATM sales transactions having an aggregate offering price of up to $2,605,728. Any shares offered and sold in these ATM sales transactions will be issued pursuant to the 2024 Shelf.

Stock Options

During the three and nine months ended December 31, 2023, under the 2022 Plan, 40,000 and 171,257 stock options were granted at various exercise prices, respectively.

On August 28, 2023, the Company's Executive Chairman voluntarily forfeited 462,500 outstanding stock options, of which 312,918 were unvested and therefore cancelled, and 149,582 were vested and therefore expired. The forfeited stock option awards were not replaced by other awards or other compensation and there is no plan to replace the forfeited awards. Therefore, all previous unrecognized compensation expense associated with the forfeited awards, approximately $519,000, was recognized as a selling, general, and administrative expense on the date of forfeiture.

The following table summarizes the Company’s stock option activity from March 31, 2023 to December 31, 2023:


	Options Outstanding			Weighted Average Exercise Price		Aggregate Intrinsic Value
Outstanding at March 31, 2023		1,451,217		$	6.49	$	38,327

The weighted average remaining contractual term of stock options exercisable and outstanding at December 31, 2023 was approximately 7.36 years.

Employee Stock Purchase Plan

In June 2016, the Board adopted, and in August 2016, the Company’s stockholders subsequently approved, the 2016 ESPP. The Company reserved 75,000 shares of common stock for issuance thereunder. As of October 31, 2023, the 2016 ESPP was replaced by the 2023 ESPP (as defined below).

In July 2023, the Board adopted, and on October 31, 2023, the Company's stockholders subsequently approved, the 2023 Employee Stock Purchase Plan (the "2023 ESPP"). The 2023 ESPP became effective on October 31, 2023 and replaced the 2016 ESPP on that date. The Company reserved 45,000 shares of common stock for issuance thereunder. The 2023 ESPP permits employees to purchase common stock through payroll deductions, limited to 15 percent of each employee’s compensation up to $25,000 per employee per year or 500 shares per employee per six-month purchase period. Shares under the 2023 ESPP are purchased at 85 percent of the fair market value at the lower of (i) the closing price on the first trading day of the six-month purchase period or (ii) the closing price on the last trading day of the six-month purchase period. The initial offering under the 2023 ESPP will commence in March 2024.

Common Stock Reserved for Future Issuance

Common stock reserved for future issuance consisted of the following at December 31, 2023:

Stock-based Compensation Expense and Valuation Information

Stock-based awards include stock options and RSUs under the 2022 Plan, 2012 Plan, Inducement Plan, and rights to purchase stock under the 2023 ESPP. The Company calculates the grant date fair value of all stock-based awards in determining the stock-based compensation expense.

Stock-based compensation expense for all stock-based awards consists of the following (in thousands):


	Three Months Ended		Three Months Ended		Nine Months Ended		Nine Months Ended
	December 31, 2023		December 31, 2022		December 31, 2023		December 31, 2022
Research and development	$	40	$	117	$	87	$	363
General and administrative		117		427		1,220		1,514
Total	$	157	$	544	$	1,307	$	1,877

The total unrecognized compensation cost related to unvested stock option grants as of December 31, 2023 was approximately $0.6 million and the weighted average period over which these grants are expected to vest is 2.30 years.

The total unrecognized compensation cost related to unvested RSUs as of December 31, 2023 was $0.2 million, which will be recognized over a weighted average period of 0.97 years.

The Company uses either the Black-Scholes or Monte Carlo option-pricing models to calculate the fair value of stock options, depending on the complexity of the equity grants. Stock-based compensation expense is recognized over the vesting period using the straight-line method. The assumed dividend yield is based on the Company’s expectation of not paying dividends in the foreseeable future. The Company uses the Company-specific historical volatility rate as the indicator of expected volatility. The risk-free interest rate assumption is based on U.S. Treasury rates. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the options. The measurement and classification of share-based payments to non-employees is consistent with the measurement and classification of share-based payments to employees. The fair value of stock options was estimated at the grant date using the following weighted average assumptions:


	Three Months Ended			Three Months Ended			Nine Months Ended			Nine Months Ended
	December 31, 2023			December 31, 2022			December 31, 2023			December 31, 2022

Weighted average grant date fair value	$	1.16		$	1.23		$	1.38		$	1.96

The fair value of each RSU is recognized as stock-based compensation expense over the vesting term of the award. The fair value is based on the closing stock price on the date of the grant.

The Company uses the Black-Scholes valuation model to calculate the fair value of shares issued pursuant to the 2016 ESPP and the 2023 ESPP. Stock-based compensation expense is recognized over the purchase period using the straight-line method. The fair value of ESPP shares was estimated at the purchase period commencement date using the following assumptions:


	Three Months Ended			Three Months Ended			Nine Months Ended			Nine Months Ended
	December 31, 2023*			December 31, 2022*			December 31, 2023*			December 31, 2022

*There were no participants in the 2016 ESPP or the 2023 ESPP for the purchase periods beginning September 1, 2022, March 1, 2023 or September 1, 2023.

The assumed dividend yield is based on the Company’s expectation of not paying dividends in the foreseeable future. The Company uses the Company-specific historical volatility rate as the indicator of expected volatility. The risk-free interest rate assumption is based on U.S. Treasury rates. The expected life is the 6-month purchase period.

Leases [Abstract]

Leases

Note 8. Leases

After the initial adoption of Accounting Standards Codification Topic 842 (“ASC 842”), on an on-going basis, the Company evaluates all contracts upon inception and determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If a lease is identified, the Company will apply the guidance from ASC 842 to properly account for the lease.

Operating Leases

On November 23, 2020, the Company entered into a lease agreement, pursuant to which the Company permanently leased approximately 8,051 square feet of lab and office space (the “Permanent Lease”) in San Diego once certain tenant improvements were completed by the landlord and the premises were ready for occupancy. Additionally, on November 17, 2021, the Permanent Lease was amended to add an additional 2,892 square feet of office space in the same building. The Permanent Lease commenced on December 17, 2021 and is intended to serve as the Company’s permanent premises for approximately sixty-two months. Monthly rental payments will be approximately $40,800 with 3% annual escalators.

The Company determined that the Permanent Lease is considered an operating lease under ASC 842, and therefore upon the lease commencement date of December 17, 2021, recognized lease liabilities and corresponding right-of-use assets of $2.3 million. The Company records operating lease expense on a straight-line basis over the life of the lease (referred to as “operating lease expense”). Variable lease expenses associated with the Company’s leases, such as payments for additional monthly fees to cover the Company’s share of certain facility expenses (common area maintenance) are expensed as incurred.

The table below summarizes the Company’s lease liabilities and corresponding right-of-use assets as of December 31, 2023 (in thousands except the year and percentage):

Variable lease expense was approximately $39,000 and $114,000 for the three and nine months ended December 31, 2023, respectively, and approximately $34,000 and $110,000 for the three and nine months ended December 31, 2022, respectively. Operating lease expense was approximately $125,000 and $377,000 for the three and nine months ended December 31, 2023, respectively, and approximately $114,000 and $373,000 for the three and nine months ended December 31, 2022, respectively.

Cash flows associated with the Company’s operating lease for the three and nine months ended December 31, 2023, were approximately $125,000 and $377,000, respectively, and approximately $59,000 and $304,000 for the three and nine months ended December 31, 2022, respectively.

Restructuring

Note 11. Restructuring

On August 18, 2023, the Company announced to its employees a plan to reduce the Company’s workforce, effective August 25, 2023, by approximately six employees, which represented approximately 24% of its employees as of August 18, 2023. The Company has refocused operations on FXR314, its clinical drug candidate. This decision to reduce the Company’s workforce was made in order to focus spending on the Company’s clinical program for FXR314, reduce ongoing operating expenses not related to clinical expenses, and extend the Company’s cash runway. The Company estimates that it will incur approximately $0.4 million of cash expenditures in connection with the reduction in force, which relate to severance pay, and are expected to be incurred through the quarter ending March 31, 2024. The Company anticipates annual cost savings of $1.5 million resulting from the reduction in force.

Approximately $0.4 million of restructuring charges were recorded during the nine months ended December 31, 2023, and no restructuring charges were recorded during the three months ended December 31, 2023.

Description of Business

Note 1. Description of Business

Nature of Operations

Organovo Holdings, Inc. (“Organovo Holdings,” “Organovo,” and the “Company”) is a clinical stage biotechnology company that focuses on clinical drug development of the farnesoid X receptor (“FXR”) agonist FXR314. FXR is a mediator of gastrointestinal and liver diseases. FXR agonism has been tested in a variety of preclinical models of inflammatory bowel disease ("IBD"). FXR314 is the lead compound in the Company's established FXR program containing two clinically tested compounds (including FXR314) and over 2,000 discovery or preclinical compounds. FXR314 is a drug with safety and tolerability after daily oral dosing in Phase 1 and Phase 2 trials. Further, FXR314 has FDA clinical trial authorization for a Phase 2 trial in ulcerative colitis ("UC").

The Company’s current clinical focus is in advancing FXR314 in IBD, including UC and Crohn’s disease (“CD”). The Company plans to start a Phase 2a clinical trial in UC in the calendar year 2024.

A second focus of the Company is building high fidelity, 3D tissues that recapitulate key aspects of human disease. The Company uses its proprietary technology to build functional 3D human tissues that mimic key aspects of native human tissue composition, architecture, function and disease. Management believes these attributes can enable critical complex, multicellular disease models that can be used to develop clinically effective drugs across multiple therapeutic areas.

As with the clinical development program, the Company is initially focusing on the intestine and has ongoing 3D tissue development efforts in human tissue models of UC and CD. The Company uses these models to identify new molecular targets responsible for driving these diseases and to explore the mechanism of action of known drugs including FXR314 and related molecules. The Company intends to initiate drug discovery programs around these new validated targets to identify drug candidates for partnering and/or internal clinical development.

The Company’s current understanding of intestinal tissue models and IBD disease models leads it to believe that it can create models that provide greater insight into the biology of these diseases than are generally currently available. The Company is creating high fidelity disease models, leveraging its prior work including the work found in its peer-reviewed publication on bioprinted intestinal tissues (Madden et al. Bioprinted 3D Primary Human Intestinal Tissues Model Aspects of Native Physiology and ADME/Tox Functions. iScience. 2018 Apr 27;2:156-167. doi: 10.1016/j.isci.2018.03.015.) Organovo’s advances include cell type-specific compartments, prevalent intercellular tight junctions, and the formation of microvascular structures.

Using these disease models, the Company intends to identify and validate novel therapeutic targets. After finding therapeutic drug targets, the Company intends to focus on developing novel small molecule, antibody, or other therapeutic drug candidates to treat the disease, and advance these novel drug candidates towards an Investigational New Drug (“IND”) filing and potential future clinical trials.

The Company expects to broaden its work into additional therapeutic areas over time and is currently exploring specific tissues for development. In the Company’s work to identify the areas of interest, it evaluates areas that might be better served with 3D disease models than currently available models as well as the potential commercial opportunity. In line with these plans, the Company is building upon both its external and in house scientific expertise, which will be essential to its drug development effort.

Except where specifically noted or the context otherwise requires, references to “Organovo Holdings”, “the Company”, and “Organovo” in these notes to the unaudited condensed consolidated financial statements refers to Organovo Holdings, Inc. and its wholly owned subsidiaries, Organovo, Inc., and Opal Merger Sub, Inc.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. 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 U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not necessarily include all information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at March 31, 2023 is derived from the Company’s audited consolidated balance sheet at that date.

The unaudited condensed consolidated financial statements include the accounts of Organovo and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are only normal and recurring, necessary for a fair statement of the Company’s financial position, results of operations, stockholders’ equity and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2023, as filed with the Securities and Exchange Commission (“SEC”). Operating results for any interim period are not necessarily indicative of the operating results for any other interim period or the Company’s full fiscal year ending March 31, 2024 (see “Note 1. Description of Business”).

Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared on the basis that we are a going concern, which contemplates, among other things, the realization of assets and satisfaction of liabilities in the normal course of business. As of December 31, 2023, the Company had cash and cash equivalents of approximately $5.3 million, restricted cash of approximately $0.1 million and an accumulated deficit of approximately $336.6 million. The restricted cash was pledged as collateral for a letter of credit that the Company is required to maintain as a security deposit under the terms of the lease agreement for its facilities. The Company also had negative cash flows from operations of approximately $12.0 million during the nine months ended December 31, 2023.

Through December 31, 2023, the Company has financed its operations primarily through the sale of common stock through public and at-the-market (“ATM”) offerings, the private placement of equity securities, from revenue derived from the licensing of intellectual property, products and research service-based services, grants, and collaborative research agreements, and from the sale of convertible notes. During the nine months ended December 31, 2023, the Company issued 934,621 shares of its common stock through its ATM facility.

Based on the Company's current operating plan and available cash resources, it will need substantial additional funding to support future operating activities. The Company has concluded that the prevailing conditions and ongoing liquidity risks faced by it raise substantial doubt about its ability to continue as a going concern for at least one year following the date these financial statements are issued. The accompanying consolidated financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern. As the Company continues its operations and is focusing its efforts on drug discovery and development, the Company will need to raise additional capital to implement this business plan. The Company cannot predict with certainty the exact amount or timing for any future capital raises. The Company will seek to raise additional capital through debt or equity financings, or through some other financing arrangement. However, the Company cannot be sure that additional financing will be available if and when needed, or that, if available, it can obtain financing on terms favorable to its stockholders. Any failure to obtain financing when required will have a material adverse effect on the Company’s business, operating results, and financial condition.

Use of Estimates

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. On an ongoing basis, management reviews these estimates and assumptions.

Investments

Investments consist of investments in debt securities and investments in equity securities.

Investments in debt securities consist of investments in U.S. Treasury bills. All investments that have original maturities of three months or less are classified as cash equivalents on the Condensed Consolidated Balance Sheets. Prior to December 31, 2022, the

Company classified certain investments as held-to-maturity. All investments previously classified as held-to-maturity matured prior to December 31, 2022. As of December 31, 2023 and March 31, 2023, all investments are classified as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies. Available-for-sale debt securities are recorded at fair value. Any unrealized gains and losses are included in accumulated other comprehensive income as a component of stockholders' equity until realized. As U.S. Treasury bills have minimal risk, any declines in fair value are considered temporary.

Investments in equity securities consist of investments in the common stock of entities traded in active markets. The Company does not have the ability to exercise significant influence over any entities. Therefore, initial investments are recorded at cost, and are remeasured at fair value as of the balance sheet date. Any gains or losses resulting from the change in fair value are recorded in net income. The investments in equity securities are classified as current assets.

Fair value measurement

Financial assets and liabilities are measured at fair value, which is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

•

Level 1 — Quoted prices in active markets for identical assets or liabilities.

•

Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Net Loss Per Share

Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares used to compute diluted loss per share excludes any assumed exercise of stock options, shares reserved for purchase under the Company’s 2016 Employee Stock Purchase Plan (“2016 ESPP”), the assumed vesting of restricted stock units (“RSUs”), and shares subject to repurchase as the effect would be anti-dilutive. No dilutive effect was calculated for each of the three and nine months ended December 31, 2023 and 2022 as the Company reported a net loss for each respective period and the effect would have been anti-dilutive.

Common stock equivalents excluded from computing diluted net loss per share due to their anti-dilutive effect were approximately 0.8 million at December 31, 2023 and 1.5 million at December 31, 2022.

Revenue recognition

The Company has generated revenues from payments received from licensing intellectual property.

The Company has entered into a license agreement with a company that includes the following: (i) non-refundable upfront fees and (ii) royalties based on specified percentages of net product sales, if any. At the initiation of the agreement, the Company has analyzed whether it results in a contract with a customer under Topic 606.

The Company has considered a variety of factors in determining the appropriate estimates and assumptions under these arrangements, such as whether the Company is a principal vs. agent, whether the elements are distinct performance obligations, whether there are determinable stand-alone prices, and whether any licenses are functional or symbolic. The Company has evaluated each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time. Typically, non-refundable upfront fees have been considered fixed, while sales-based royalty payments have been identified as variable consideration which must be evaluated to determine if it has been constrained and, therefore, excluded from the transaction price. Please refer to “Note 6: Collaborative Research, Development, and License Agreements” for further information.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies. Unless otherwise stated, the Company believes that the impact of the recently issued accounting

pronouncements that are not yet effective will not have a material impact on its consolidated financial position or results of operations upon adoption.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not necessarily include all information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at March 31, 2023 is derived from the Company’s audited consolidated balance sheet at that date. The unaudited condensed consolidated financial statements include the accounts of Organovo and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are only normal and recurring, necessary for a fair statement of the Company’s financial position, results of operations, stockholders’ equity and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2023, as filed with the Securities and Exchange Commission (“SEC”). Operating results for any interim period are not necessarily indicative of the operating results for any other interim period or the Company’s full fiscal year ending March 31, 2024 (see “Note 1. Description of Business”).
Liquidity and Going Concern	Liquidity and Going Concern The accompanying consolidated financial statements have been prepared on the basis that we are a going concern, which contemplates, among other things, the realization of assets and satisfaction of liabilities in the normal course of business. As of December 31, 2023, the Company had cash and cash equivalents of approximately $5.3 million, restricted cash of approximately $0.1 million and an accumulated deficit of approximately $336.6 million. The restricted cash was pledged as collateral for a letter of credit that the Company is required to maintain as a security deposit under the terms of the lease agreement for its facilities. The Company also had negative cash flows from operations of approximately $12.0 million during the nine months ended December 31, 2023. Through December 31, 2023, the Company has financed its operations primarily through the sale of common stock through public and at-the-market (“ATM”) offerings, the private placement of equity securities, from revenue derived from the licensing of intellectual property, products and research service-based services, grants, and collaborative research agreements, and from the sale of convertible notes. During the nine months ended December 31, 2023, the Company issued 934,621 shares of its common stock through its ATM facility. Based on the Company's current operating plan and available cash resources, it will need substantial additional funding to support future operating activities. The Company has concluded that the prevailing conditions and ongoing liquidity risks faced by it raise substantial doubt about its ability to continue as a going concern for at least one year following the date these financial statements are issued. The accompanying consolidated financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern. As the Company continues its operations and is focusing its efforts on drug discovery and development, the Company will need to raise additional capital to implement this business plan. The Company cannot predict with certainty the exact amount or timing for any future capital raises. The Company will seek to raise additional capital through debt or equity financings, or through some other financing arrangement. However, the Company cannot be sure that additional financing will be available if and when needed, or that, if available, it can obtain financing on terms favorable to its stockholders. Any failure to obtain financing when required will have a material adverse effect on the Company’s business, operating results, and financial condition.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. On an ongoing basis, management reviews these estimates and assumptions.
Investments	Investments Investments consist of investments in debt securities and investments in equity securities. Investments in debt securities consist of investments in U.S. Treasury bills. All investments that have original maturities of three months or less are classified as cash equivalents on the Condensed Consolidated Balance Sheets. Prior to December 31, 2022, the Company classified certain investments as held-to-maturity. All investments previously classified as held-to-maturity matured prior to December 31, 2022. As of December 31, 2023 and March 31, 2023, all investments are classified as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies. Available-for-sale debt securities are recorded at fair value. Any unrealized gains and losses are included in accumulated other comprehensive income as a component of stockholders' equity until realized. As U.S. Treasury bills have minimal risk, any declines in fair value are considered temporary. Investments in equity securities consist of investments in the common stock of entities traded in active markets. The Company does not have the ability to exercise significant influence over any entities. Therefore, initial investments are recorded at cost, and are remeasured at fair value as of the balance sheet date. Any gains or losses resulting from the change in fair value are recorded in net income. The investments in equity securities are classified as current assets.
Fair value measurement	Fair value measurement Financial assets and liabilities are measured at fair value, which is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Net Loss Per Share	Net Loss Per Share Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares used to compute diluted loss per share excludes any assumed exercise of stock options, shares reserved for purchase under the Company’s 2016 Employee Stock Purchase Plan (“2016 ESPP”), the assumed vesting of restricted stock units (“RSUs”), and shares subject to repurchase as the effect would be anti-dilutive. No dilutive effect was calculated for each of the three and nine months ended December 31, 2023 and 2022 as the Company reported a net loss for each respective period and the effect would have been anti-dilutive. Common stock equivalents excluded from computing diluted net loss per share due to their anti-dilutive effect were approximately 0.8 million at December 31, 2023 and 1.5 million at December 31, 2022.
Revenue recognition	Revenue recognition The Company has generated revenues from payments received from licensing intellectual property. The Company has entered into a license agreement with a company that includes the following: (i) non-refundable upfront fees and (ii) royalties based on specified percentages of net product sales, if any. At the initiation of the agreement, the Company has analyzed whether it results in a contract with a customer under Topic 606. The Company has considered a variety of factors in determining the appropriate estimates and assumptions under these arrangements, such as whether the Company is a principal vs. agent, whether the elements are distinct performance obligations, whether there are determinable stand-alone prices, and whether any licenses are functional or symbolic. The Company has evaluated each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time. Typically, non-refundable upfront fees have been considered fixed, while sales-based royalty payments have been identified as variable consideration which must be evaluated to determine if it has been constrained and, therefore, excluded from the transaction price. Please refer to “Note 6: Collaborative Research, Development, and License Agreements” for further information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies. Unless otherwise stated, the Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its consolidated financial position or results of operations upon adoption.

Note 6. Collaborative Research, Development, and License Agreements

License Agreements

From June 2021 to February 2022, certain patents owned or sublicensed by the Company became the subject of inter partes review proceedings filed by Cellink AB and its subsidiaries (collectively, “BICO Group AB”). The Company and BICO Group AB were also engaged in litigation regarding patent infringement during the same time period. On February 22, 2022, the Company and BICO Group AB signed a settlement and patent license agreement (“License Agreement”) to close all matters noted above. In addition to closing all legal matters and patent disputes noted above, as part of the agreement, the Company agreed to grant a non-exclusive license to BICO Group AB to use the Company’s aforementioned patents for its business operations of manufacturing and selling bioprinters as well as bioinks. The Company concluded that the nature of the license granted represents functional intellectual property.

As part of the License Agreement, BICO Group AB agreed to pay the Company ongoing sales-based royalties (based on percentages of BICO Group AB’s net sales) for the use of the granted license. The sales-based royalties became effective beginning on February 22, 2022, the effective date of the License Agreement, and continue until the expiration of the last surviving licensed patent. As the sales-based royalties are required to be paid 45 days after the end of every quarter, there is variable consideration that must be estimated to determine royalty revenue within a given reporting period. Once actual revenue earned is determined in the following fiscal quarter, an adjustment is made from the previously estimated amount. The Company estimated royalty revenue of $33,000 for the three months ended December 31, 2023. However, there was a decrease adjustment of approximately $28,000 relating to the prior quarter. For the three and nine months ended December 31, 2023, the Company recorded $5,000 and $80,000 of royalty revenue based on sales-based royalties from the License Agreement, respectively.

Also as part of the License Agreement, certain patents involved in the agreement are sublicensed by the Company from the University of Missouri and Clemson University. See below for further information.

University of Missouri

In March 2009, the Company entered into a license agreement with the Curators of the University of Missouri ("University of Missouri") to in-license certain technology and intellectual property relating to self-assembling cell aggregates and intermediate cellular units. The Company received the exclusive worldwide rights to commercialize products comprising this technology for all fields of use. The Company is required to pay the University of Missouri royalties ranging from 1% to 3% of net sales of covered tissue products, and of the fair market value of covered tissues transferred internally for use in the Company’s commercial service business, depending on the level of net sales achieved by the Company each year.

The license agreement with the University of Missouri also includes an additional sales royalty of 3% of all revenue received from a sublicensee, when such sublicense is entered pursuant to settlement of litigation. Such revenue shall include, but not be limited to, all option fees, license issue fees (up-front payments), license maintenance fees, equity, and all royalty payments. Such revenue shall not include research funding provided to licensee by sublicensee. However, per the agreement, in the event that the Company defends the technology by litigation, it can offset any royalties due by legal expenses incurred. No royalty expense related to sales-based royalties has been recorded to date.

On December 5, 2022, the Company amended the license agreement with the University of Missouri, where the Company agreed to pay a single, up-front payment of $50,000 to the University of Missouri in exchange for the aforementioned licensed intellectual property to be fully paid up by the Company. As a result, the Company will continue to have rights to the licensed intellectual property until its expiration, but will no longer owe minimum annual royalty payments, royalty payments based on net sales, or any other payments (other than patent annuities and any prosecution costs) in the future.

Clemson University

In May 2011, the Company entered into a license agreement with Clemson University Research Foundation ("CURF") to in-license certain technology and intellectual property relating to ink-jet printing of viable cells. The Company received the exclusive worldwide rights to commercialize products comprising this technology for all fields of use. The Company is required to pay CURF royalties ranging from 1.5% to 3% of net sales of covered tissue products and the fair market value of covered tissues transferred internally for use in the Company’s commercial service business, depending on the level of net sales reached each year. The license agreement terminates upon expiration of the patents licensed, which are expected to expire in May 2024, and is subject to certain conditions as defined in the license agreement. Minimum annual royalty payments of $20,000 were due for two years beginning in calendar 2014, and $40,000 per year beginning in calendar 2016. Royalty payments of $40,000 were made in each of the years ended March 31, 2023 and 2022. The annual minimum royalty is creditable against royalties owed during the same calendar year.

In addition to the annual royalties noted above, CURF is owed 40% of all payments including but not limited to, upfront payments, license fees, issue fees, maintenance fees, and milestone payments received from third parties, including sublicensees, in consideration for sublicensing rights to licensed products. However, per the agreement, in the event that the Company defends the technology by litigation, it can offset any royalties due by legal expenses incurred. As of December 31, 2023, the Company’s legal expenses exceeded royalties owed from the upfront payment and sales-based royalties related to the license agreement. Therefore, no royalty expense to CURF was recorded for the nine months ended December 31, 2023. No royalty expense related to sales-based royalties has been recorded to date.
