You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes beginning on page F-1 of this Annual Report. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the section entitled "Item 1A. Risk Factors" and "Special Note Regarding Forward-Looking Statements" of this Annual Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

Historically, we have been primarily focused on the development and commercialization of novel abuse-deterrent medications for CNS disorders. Our lead investigational product candidate, ADAIR, was a proprietary, abuse-deterrent oral formulation of immediate-release dextroamphetamine (the main active ingredient in Adderall®), which was being developed for the treatment of attention-deficit/hyperactivity disorder (ADHD) and narcolepsy. In March 2022, we announced that our Study to Evaluate the Abuse Liability, Pharmacokinetics, Safety and Tolerability of an Abuse-Deterrent d-Amphetamine Sulfate Immediate Release Formulation (SEAL) study for ADAIR did not reach its primary endpoint. In addition to ADAIR, our second product candidate, ADMIR, an abuse deterrent formulation of methylphenidate (Ritalin®), was also being developed for the treatment of ADHD.

While assessing the best path forward for the ADAIR and ADMIR development programs in relation to the results of the SEAL study, we engaged Ladenburg Thalmann & Co. Inc. (Ladenburg) to evaluate our strategic alternatives with the goal of maximizing stockholder value. Ladenburg was engaged to advise on the strategic review process, which could have included, without limitation, exploring the potential for a possible merger, business combination, investment into us, or a purchase, license or other acquisition of assets. In conjunction with the exploration of strategic alternatives, we streamlined operations to preserve our capital and cash resources.

After conducting a diligent and extensive process of evaluating strategic alternatives and identifying and reviewing potential candidates for a strategic acquisition or other transaction, which included the receipt of 15 formal merger proposals from interested parties and careful evaluation and consideration of those proposals, and following extensive negotiation with a number of possible candidates, on December 13, 2022, Vallon and GRI Bio, Inc. (GRI) entered into an Agreement and Plan of Merger (the Merger Agreement), pursuant to which a wholly-owned subsidiary of Vallon will merge with and into GRI, with GRI surviving as a wholly-owned subsidiary of Vallon (the Merger). The Merger will result in a clinical-stage biotechnology company focused on discovering, developing, and commercializing innovative therapies targeting serious diseases associated with dysregulated immune responses that lead to inflammatory, fibrotic, and autoimmune disorders.

At the effective time of the Merger (the Effective Time), each share of common stock of GRI, $0.01 par value per share (GRI Common Stock) outstanding immediately prior to the Effective Time, excluding any dissenting shares but including any shares of GRI Common Stock issued pursuant to the concurrent equity financing will be automatically converted into the right to receive a number of shares of common stock of Vallon, $0.0001 par value per share (Vallon Common Stock) equal to the exchange ratio, subject to adjustment for the proposed reverse stock split of Vallon Common Stock to be implemented prior to the consummation of the Merger as discussed in this Annual Report (the Reverse Split). The exchange ratio may be adjusted based on Vallon's net cash at Closing and/or any reduction to Vallon's valuation required in order to meet the initial listing requirements of The Nasdaq Stock Market LLC (Nasdaq).

Medice License Agreement

In January 2020, we entered into a license agreement with Medice ("Medice License Agreement"), which grants Medice an exclusive license to develop, use, manufacture, market and sell ADAIR throughout Europe. Under the Medice License Agreement, Medice paid a $0.1 million upfront payment and will pay milestone payments of up to $6.3 million in aggregate upon achieving certain regulatory and sales milestones. We are also entitled to low-double digit tiered royalties on net sales of ADAIR.

COVID-19

The global COVID-19 pandemic continues to present uncertainty and unforeseeable new risks to our operations and business plan. We have closely monitored recent COVID-19 developments, including the lifting of COVID-19 safety measures, the drop in vaccination rates, the implementation of, and reaction to, vaccine mandates, the spread of new strains or variants of the coronavirus (such as the Delta and Omicron variants), and supply chain and labor shortages. In light of these developments, the full impact of the COVID-19 pandemic on our business and operations remains uncertain and will vary depending on the pandemic's future impact on the third parties with whom we do business, as well as any legal or regulatory consequences resulting therefrom. To the extent possible, we are conducting business as usual, with necessary or advisable modifications to employee travel and with most of its employees and consultants working remotely. We will continue to actively monitor the COVID-19 pandemic and may take further actions that alter its operations, including those that may be required by federal, state or local authorities, or that it determines are in the best interests of its employees and other third parties with whom we do business.

Critical Accounting Policies

Our financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of



                                       30

--------------------------------------------------------------------------------

Table of Contents

assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.

Marketable Securities

Marketable securities consist of debt securities that are designated as available-for-sale. Marketable debt securities are recorded at fair value and unrealized holding gains or losses are reported as a component of accumulated other comprehensive income (loss). The amortization of discounts and premiums on marketable securities is included in interest expense, net on the statements of operations and comprehensive loss.

Realized gains or losses resulting from the sale of these securities are determined based on the specific identification of the securities sold. An impairment charge is recognized when the decline in the fair value of a debt security below the amortized cost basis is determined to be other-than-temporary. We consider various factors in determining whether to recognize an impairment charge, including the duration and severity of any decline in fair value below the amortized cost basis, any adverse changes in the financial condition of the issuers and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value.

Revenue Recognition

We account for revenue in accordance with Financial Accounting Standards Board Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers. This standard applies to all contracts with customers with the exception of contracts that are within the scope of other standards, such as leases, insurance and financial instruments. Under ASC Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to be entitled in exchange for those goods or services.

We perform the following five steps to recognize revenue under ASC Topic 606: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only recognize revenue when it is probable that we will collect the consideration to which we are entitled in exchange for the goods or services that will be transferred to the customer.

To date, our revenues have been generated by a single license agreement (the Medice License Agreement) with Medice (Note 13). The Medice License Agreement included an exclusive license to develop, use, manufacture, market and sell ADAIR throughout Europe, a non-refundable up-front payment, regulatory and sales milestones and royalty payments.

Stock-based Compensation

We recognize expense for employee and non-employee stock-based compensation in accordance with ASC Topic 718, Compensation-Stock Compensation. ASC Topic 718 requires that such transactions be accounted for using a fair value-based method. The estimated fair value of the options is amortized over the vesting period, based on the fair value of the options on the date granted, and is calculated using the Black-Scholes option-pricing model. We account for forfeitures as incurred.

Estimating the fair value of option shares issued under the employee stock purchase plan requires the input of subjective assumptions, including the estimated fair value of our common stock, the expected life of the option, stock price volatility, the risk-free interest rate and expected dividends. The assumptions used in our Black-Scholes option-pricing model represent management's best estimates and involve a number of variables, uncertainties and assumptions and the application of management's judgment, as they are inherently subjective. If any assumptions change, our stock-based compensation expense could be materially different in the future.

These assumptions used in our Black-Scholes option-pricing model are estimated as follows:

•Expected Term. Due to the lack of sufficient company-specific historical data, the expected term of employee options is determined using the "simplified" method, as prescribed in SEC's Staff Accounting Bulletin (SAB) No. 107, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option. The expected term of nonemployee options is equal to the contractual term.



                                       31

--------------------------------------------------------------------------------

Table of Contents

•Expected Volatility. The expected volatility is based on historical volatilities of similar entities within our industry which were commensurate with the expected term assumption as described in SAB No. 107.

•Risk-Free Interest Rate. The risk-free interest rate is based on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected term.

•Expected Dividends. The expected dividend yield is 0% because we have not historically paid, and do not expect for the foreseeable future to pay, a dividend on our common stock.

Leases

We account for leases in accordance with Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) and ASU 2018-10, Codification Improvements to Topic 842, Leases, and ASU 2018-11, Leases (Topic 842): Targeted Improvements, both of which clarify and enhance the certain amendments made in ASU 2016-02. The ASUs increase transparency and comparability among entities by recognizing for all leases lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. We entered into one lease for manufacturing equipment for ADAIR which we determined was a finance lease.

Financial Operations Overview

Research and Development Expenses

Research and development expenses include personnel costs associated with research and development activities, including third party contractors to perform research, conduct clinical trials and manufacture drug supplies and materials. We accrue for costs incurred by external service providers, including contract research organizations and clinical investigators, based on its estimates of service performed and costs incurred.

Our research and development expenses have consisted primarily of in-process research and development expenses, costs incurred in preparing for and conducting the development program for ADAIR, working on commercial manufacturing of ADAIR and developing formulations for ADMIR. Research and development costs are expensed as incurred. These expenses include:

•employee -related expenses, such as salaries, bonuses and benefits, consultant-related expenses such as consultant fees and bonuses, stock-based compensation, overhead related expenses and travel related expenses for our research and development personnel;

•expenses incurred under agreements with contract research organizations (CROs), as well as consultants that support the implementation of our clinical and non-clinical studies;

•manufacturing and packaging costs in connection with conducting clinical trials and for stability and other studies required to support the NDA filing as well as manufacturing drug product for commercial launch;

•formulation, research and development expenses related to ADMIR; and other products we may choose to develop; and

•costs for sponsored research.

We typically use our employee, consultant and infrastructure resources across our research and development programs. Although we track certain outsourced development costs by product candidate, we do not allocate personnel costs or other internal costs to specific product candidates.

Our research and development expenses have significantly decreased and will continue to decrease as we considers our future plans regarding the ADAIR and ADMIR programs and as a result of the proposed Merger.

General and Administrative Expenses

General and administrative expenses consist primarily of compensation and consulting related expenses for executives and other administrative personnel, professional fees and other corporate expenses, including legal and accounting fees, travel expenses, facilities-related expenses, and consulting services relating to our formation and corporate matters.

We incur costs associated with being a public company, including expenses related to services associated with maintaining compliance with The Nasdaq Capital Market and SEC requirements, directors and officers insurance, legal and accounting costs and investor relations costs. Our general and administrative expenses have increased are expected to continue to increase due to increases in professional and advisory fees as a result of the proposed Merger.

Other Income

Other income consists of income recognized as a result of the extinguishment of the promissory note issued to us under the Paycheck Protection Program (PPP) as a result of the forgiveness of the note.

Revaluation of Derivative Instruments

In January 2021, we entered into a Convertible Promissory Note Purchase Agreement pursuant to which we issued $350,000 in convertible promissory notes (the 2021 Convertible Notes). The 2021 Convertible Notes automatically converted into 54,906 shares of our common stock concurrently with the closing of the IPO. We identified the mandatory conversion into shares our common stock as a redemption feature, which requires bifurcation from the 2021 Convertible Notes and treated it as a derivative liability under ASC 815 as the redemption feature was not clearly and closely related to the debt. We evaluated the fair value of the derivative liability at issuance. Upon the conversion of the 2021 Convertible Notes to common stock at the closing of the IPO, the embedded derivative liability was remeasured and removed from the balance sheet.

Warrant Liability, Change in Fair Value and Warrant Conversion

We evaluated the warrants issued in connection with the May 2022 registered direct financing in accordance with ASC 815-40, Derivatives and Hedging - Contracts in Entity's Own Equity (ASC 815-40), and concluded that a provision in the warrants related to the reduction of the exercise price in certain circumstances precludes the warrants from being accounted for as components of equity. As the warrants meet the definition of a derivative as contemplated in ASC 815, the warrants are recorded as derivative liabilities on the Balance Sheets and measured at fair value at inception and at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized in the accompanying Statements of Operations and Comprehensive Loss in the period of change. The derivative liabilities will ultimately be converted into our common stock when the warrants are exercised, or will be extinguished upon expiry of the warrant term. Upon exercise, the intrinsic value of the shares issued will be transferred to stockholders' equity. The difference between the intrinsic value of the stock issued and the fair value of the warrant is recorded as gain or loss on the exchange in the accompanying Statements of Operations and Comprehensive Loss in the period of exercise.

Interest Income (Expense), net

Interest income (expense), net, consists of interest earned on our cash, cash equivalents and marketable securities held with institutional banks, the amortization of discounts and accretion of premiums on marketable securities and interest expense on our finance lease of equipment utilized in the commercial scale manufacturing of ADAIR.

Recently Issued Accounting Pronouncements

We consider the applicability and impact of all ASUs. ASUs not discussed below were assessed and determined to be either not applicable or are expected to have minimal impact on the financial statements.

On January 1, 2022, we adopted ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40). ASU 2020-06 address issues identified as a result of the complexity associated with applying generally accepted accounting principles (GAAP) for certain financial instruments with characteristics of liabilities and equity.The amendments focused on amending the guidance on convertible instruments and the guidance on the derivatives scope exception for contracts in an entity's own equity. The adoption of this standard did not have a material impact on our financial statements.

On January 1, 2021, we adopted ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principals in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending the existing guidance. The adoption of this standard did not have a material impact on our financial statements.

Emerging Growth Company Status

Vallon is an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and may remain an emerging growth company for up to five years. For so long as Vallon remains an emerging growth company, Vallon is permitted and intends to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

•reduced disclosure about its executive compensation arrangements;

•no non-binding stockholder advisory votes on executive compensation or golden parachute arrangements; and



                                       33

--------------------------------------------------------------------------------

Table of Contents

•exemption from the auditor attestation requirement in the assessment of its internal control over financial reporting.

Vallon has taken advantage of reduced reporting requirements in this Annual Report and may continue to do so until such time that we are no longer an emerging growth company. Emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. Therefore, Vallon may not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Vallon will remain an emerging growth company until the earliest of (a) the last day of the fiscal year in which it has total annual gross revenues of $1.235 billion or more, (b) December 31, 2026, the last day of the fiscal year following the fifth anniversary of the completion of the IPO, (c) the date on which it has issued more than $1.0 billion in nonconvertible debt during the previous three years or (d) the date on which Vallon is deemed to be a large accelerated filer under the rules of the SEC. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period for complying with new or revised accounting standards.

Research and Development Expenses

Research and development expenses were $1.2 million and $5.2 million for the years ended December 31, 2022 and 2021, respectively. The $4.0 million decrease in research and development expenses was primarily due to decreases of $3.3 million in expenses related to the registration development program of ADAIR, $0.4 million in personnel expense, including non-cash stock compensation, of $0.3 million, $0.2 million in consulting fees, and a decrease of $0.1 million in expenses related to the formulation work for ADMIR.

General and Administrative Expenses

General and administrative expenses were $5.8 million and $4.1 million for the years ended December 31, 2022 and 2021, respectively. The $1.7 million increase was primarily related to increased costs as a result of our evaluation of strategic alternatives.

Other Income

In May 2020, we issued a promissory note under the PPP totaling $61,000. As of December 31, 2020, we had utilized the entire proceeds from such note for payroll costs (greater than 75%), costs related to health care benefits and rent payments. In January 2021, we were notified that the note along with accumulated interest had been forgiven. As a result, we recorded income from the extinguishment of the obligation in accordance with ASC 405-20-40-1.

Revaluation of Derivative Liability

During the year ended December 31, 2021, pursuant to ASC 815, we revalued the embedded derivative liability associated with the 2021 Convertible Notes as a result of the conversion of the 2021 Convertible Notes to common stock at the closing of the



                                       34

--------------------------------------------------------------------------------

Table of Contents

IPO. The embedded derivative liability was remeasured and removed from the balance sheet, resulting in an $89,000 decrease in the fair value of the derivative liability associated with the 2021 Convertible Notes.

Change in Fair Value of Warrant Liability and Loss on Warrant Conversion

In May 2022, we issued 3,700,000 shares of common stock pursuant to a securities purchase agreement at a purchase price of $1.0632 per share in a registered direct offering. In connection with the registered direct offering, we issued warrants to purchase an aggregate of 3,700,000 shares of common stock at an exercise price of $0.9382 per share (May 2022 Warrant Agreement). The warrants were classified as a liability in accordance with ASC 815-40 and the fair value of $1.3 million was recorded as a liability at inception.

The May 2022 Warrant Agreement entitled the holders to receive one share of common stock for each warrant in lieu of the aggregate number of shares of common stock that would have been received using the cashless exercise formula set forth in the May 2022 Warrant Agreement (Alternate Cashless Exercise). In July 2022, we amended the terms of the May 2022 Warrant Agreement to obligate each warrant holder who signed the warrant amendment (Applicable Holder) to effect an Alternate Cashless Exercise, in whole, by August 10, 2022 (the Expiration Date). If the warrants held by the Applicable Holders were not exercised by the Expiration Date, they were automatically exercised pursuant to the Alternate Cashless Exercise. A total of 2,220,000 warrants were exercised pursuant to the May 2022 Warrant Agreement amendment. In December 2022, an additional 740,000 warrants were exercised pursuant to the Alternate Cashless Exercise under the original terms of the May 2022 Warrant Agreement. As a result of the warrant conversions, we recognized a $0.8 million reversal of the warrant liability and a loss of $0.5 million.

The change in fair value of $0.4 million represents a decrease in the fair value of the warrants outstanding during the year ended December 31, 2022.

Interest Income (Expense), net

Interest income, net, was $26,000 for the year ended December 31, 2022. Interest expense, net, was $16,000 for the year ended December 31, 2021.

Liquidity and Capital Resources

Since inception, we have incurred losses and expect to continue to incur losses for the foreseeable future. We incurred net losses of $7.0 million and $9.3 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $28.9 million.

We have financed our working capital requirements to date through the issuance of common stock, convertible notes, short-term promissory notes, and a PPP promissory note. As of December 31, 2022, we had $3.8 million in cash and cash equivalents.



The following table summarizes our cash flows for the periods indicated (in
thousands):

Net increase in cash and cash equivalents $ 79 $ 3,593

Cash Flows from Operating Activities

For the years ended December 31, 2022 and 2021, $7.1 million and $8.3 million were used in operating activities, respectively. The $1.2 million decrease was primarily due to a $2.3 million decrease in our net loss and a decrease of $0.5 million in cash used for prepaid and other expenses and accounts payable, offset by a $0.4 million decrease in non-cash adjustments, including stock based compensation expense, the change in fair value of the warrant liability, and the loss on warrant conversion, and a $1.3 million increase in cash used for the payment of accrued expenses.

Cash Flows from Investing Activities

Net cash provided by investing activities was $3.8 million for the year ended December 31, 2022, which was primarily related to the maturities of marketable securities. Net cash used in investing activities was $3.8 million for the year ended December 31, 2021, which was related to the purchase of marketable securities.

Cash Flows from Financing Activities

Net cash provided by financing activities was $3.4 million during the year ended December 31, 2022, which was related to which was related to the net proceeds from the registered direct financing in May 2022. Net cash provided by financing activities was $15.7 million for the year ended December 31, 2021 and was primarily related to the net proceeds from our IPO and 2021 Convertible Notes financings.

2021 Convertible Note Financing

In January 2021, we entered into a Convertible Promissory Note Purchase Agreement with certain existing stockholders, including Salmon Pharma, an affiliate of Medice, and David Baker, our Chief Executive Officer, pursuant to which we issued convertible promissory notes (the 2021 Convertible Notes) for cash proceeds of $350,000. The 2021 Convertible Notes bear an interest rate of 7.0% per annum, non-compounding, and had a maturity date of September 30, 2021. The 2021 Convertible Notes were convertible into shares of our capital stock offered to investors in any subsequent equity financing after the date of their issuance in which we issued any of our equity securities (a Qualified Financing) and were convertible at a twenty percent discount to the price per share offered in such Qualified Financing. Such Qualified Financing included the IPO of our common stock, consummated on February 12, 2021; therefore, the 2021 Convertible Notes converted into an aggregate of 54,906 shares of our common stock immediately prior to the closing of the IPO, as agreed upon among the parties thereto.

Future Funding Requirements

To date, we have not generated any revenue from the sale of any products. Substantially all of our revenue to date has been generated by the Medice license agreement from which we received a $0.1 million license fee in January 2020. We do not know when, or if, we will generate any revenue. In March 2022, we announced that the SEAL study of ADAIR for the treatment of ADHD did not meet statistical significance for its primary endpoint and that we are evaluating our strategic alternatives with the goal of maximizing stockholder value. While assessing the best path forward for the ADAIR and ADMIR development programs in relation to the results of the SEAL study, we engaged Ladenburg to evaluate our strategic alternatives with the goal of maximizing stockholder value. On December 13, 2022, Vallon and GRI Bio, Inc. (GRI) entered into an Agreement and Plan of Merger, pursuant to which a wholly-owned subsidiary of Vallon will merge with and into GRI, with GRI surviving as a wholly-owned subsidiary of Vallon. The Merger will result in a clinical-stage biotechnology company focused on discovering, developing, and commercializing innovative therapies targeting serious diseases associated with dysregulated immune responses that lead to inflammatory, fibrotic, and autoimmune disorders.

Although we have entered into the Merger Agreement and intend to consummate the transaction, there is no assurance that we will be able to successfully consummate the proposed merger on a timely basis, or at all. If, for any reason, the merger is not completed, we will reconsider our strategic alternatives and could pursue one or more of the following courses of action:

•Dissolve and liquidate our assets. If, for any reason, the merger is not consummated and we are unable to identify and complete an alternative strategic transaction like a merger or potential collaborative, partnering or other strategic arrangements for our assets, or continue to operate our business due to the inability to raise additional funding, we may be required to dissolve and liquidate our assets. In such case, there can be no assurances as to the amount or timing of available cash left to distribute to our stockholders, if any, after paying our debts and other obligations and setting aside funds for reserves.

• Pursue potential collaborative, partnering or other strategic arrangements for our assets, including a sale or other divestiture.

• Continue to operate our business. Although presently not anticipated, we could elect to continue to operate our business and pursue licensing or partnering transactions. Based on our prior assessment, this would require a significant amount of time, financial resources, human capital and we would be subject to all the risk and uncertainties involved in the development of product candidates. In such instance, there is no assurance that we could raise sufficient capital to support these efforts, that our development efforts would be successful or that we could successfully obtain the regulatory approvals required to market any product candidate we pursued.

• Pursue another strategic transaction like the proposed merger.

Our ability to continue as a going concern is dependent on raising capital from the sale of our common stock and/or obtaining debt financing. Our future capital requirements are difficult to forecast and will depend on many factors, including but not limited to the closing of the Merger or the terms and timing of any other strategic alternatives including a merger or business combination, asset acquisitions or sales, collaborations or licensing arrangements. Our ability to remain a going concern is wholly dependent upon our ability to continue to obtain sufficient capital to fund our operations.

Despite our ability to secure capital in the past, there can be no assurance that additional equity or debt financing will be available to us when needed or that we may be able to secure funding from any other sources. In the event that we are not able to secure funding, we may be forced to curtail operations, delay or stop ongoing clinical trials, cease operations altogether, or file for bankruptcy.

If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Any future debt financing may impose upon us covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. Any equity or debt financing may contain terms that are not favorable to us or our stockholders. If we are unable to raise additional funds when needed, we may be required to delay, reduce or terminate some or all of our development programs and clinical trials. We may also be required to sell or license to other parties' rights to develop or commercialize our drug candidates that we would prefer to retain. Therefore, there is substantial doubt about our ability to continue as a going concern. We expect to continue to incur expenses and operating losses at least for the foreseeable future as we evaluate future plans for the ADAIR and ADMIR programs as well as our strategic alternatives.

See the "Risk Factors" section of this Annual Report for additional risks associated with our substantial capital requirements.

Contractual Obligations and Other Commitments

We enter into contracts in the normal course of business with third-party contract organizations for clinical trials, preclinical studies, manufacturing and other services and products for operating purposes. These contracts generally provide for termination following a certain period after notice and therefore we believe that our non-cancelable obligations under these agreements are not material.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.
