These statements are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain. Given these uncertainties, you should not place undue reliance on any of the forward-looking statements included in this Quarterly Report. In addition, this Quarterly Report also contains estimates, projections, and other information concerning our industry, our business, and the markets for our product candidates, as well as data regarding market research, estimates, and forecasts prepared by our management. Information that is based on estimates, forecasts, projections, market research, or similar methodologies is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances reflected in this information.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Organization and Description of the Business

Armata Pharmaceuticals, Inc. (“Armata”) together with its subsidiaries (the “Company”), is a clinical-stage biotechnology company focused on the development of pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections using its proprietary bacteriophage-based technology.

Armata’s common stock, par value $0.01 per share (the “Common Stock”) is traded on the NYSE American exchange under the ticker symbol “ARMP.”.

2. Liquidity and Going Concern

The Company has incurred significant operating losses since inception and has primarily relied on equity, debt and grant financing to fund its operations. As of March 31, 2024, the Company had an accumulated deficit of $333.8 million. The Company expects to continue to incur substantial losses, and its transition to profitability will depend on the successful development, approval and commercialization of product candidates and on the achievement of sufficient revenues to support its cost structure. The Company may never achieve profitability, and unless and until then, the Company will need to continue to raise additional capital. Existing cash of $37.9 million as of March 31, 2024 will not be sufficient to fund the Company’s operations for the next 12 months from the date of these condensed consolidated financial statements. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern.

The Company has prepared its condensed consolidated financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its liabilities in the normal course of business. The accompanying condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern.

Recent Financing:

2024 Credit Agreement

On March 4, 2024, the Company entered into a credit and security agreement (the “2024 Credit Agreement”) for a loan in an aggregate amount of $35.0 million (the “2024 Loan”) with Innoviva Strategic Opportunities LLC, a wholly owned subsidiary of Innoviva, Inc. (NASDAQ: INVA), our principal stockholder and a related party (collectively, “Innoviva”). The 2024 Loan bears interest at an annual rate of 14% and matures on June 4, 2025. Principal and accrued interest are payable at maturity. Repayment of the 2024 Loan is guaranteed by the Company’s domestic subsidiaries, and the loan is secured by substantially all of the assets of the Company and the subsidiary guarantors. Concurrently with the execution of the 2024 Credit Agreement, the Company amended certain provisions of its existing convertible loan (the “Convertible Loan”) (see Note 7) and secured credit and security agreement, dated January 10, 2023, with Innoviva (the “Convertible Credit Agreement”) and its existing secured term loan facility (the “2023 Loan”) and credit and security agreement, dated July 10, 2023, with Innoviva (the “2023 Credit Agreement”) to, among other things, conform certain terms relating to permitted indebtedness and permitted liens (see Note 8).

The Company plans to raise additional capital through equity offerings, debt financings, or other capital sources, including potential collaborations, licenses and other similar arrangements. While the Company believes this plan to raise additional funds will alleviate the conditions that raise substantial doubt about the Company’s ability to continue as a going concern, these plans are not entirely within its control and cannot be assessed as being probable of occurring. The Company’s ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, financial markets in the United States and worldwide. The

Table of Contents

Company may not be able to secure additional financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity securities to raise additional funds, its existing stockholders may experience dilution, and the new equity securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products on terms that are not favorable to the Company. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or other operations. If any of these events occur, the Company’s ability to achieve the development and commercialization goals would be adversely affected.

3. Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes thereto as of and for the year ended December 31, 2023 included in the Company’s Form 10-K, filed with the Securities and Exchange Commission (the “SEC”) on March 21, 2024. The information as of December 31, 2023 included in the condensed consolidated balance sheets was derived from the Company’s audited financial statements. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the requirements of the SEC for interim reporting. In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments that are of a normal and recurring nature and that are necessary for the fair presentation of the Company’s financial position and the results of its operations and cash flows for the periods presented. Interim results are not necessarily indicative of results for the full year or any future period.

Any reference in the condensed consolidated financial statements to applicable guidance is meant to refer to authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Significant Accounting Policies

The significant accounting policies used in preparation of the condensed consolidated financial statements for the three months ended March 31, 2024 and 2023 are consistent with those discussed in Note 3 to the consolidated financial statements included in the Company’s Form 10-K for the year ended December 31, 2023, filed with the SEC on March 21, 2024, except as noted below and within the “Recently Adopted Accounting Pronouncements” section.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. 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 the condensed consolidated financial statements, and the reported amounts of expenses during the reporting period. On an ongoing basis, the Company evaluates estimates and assumptions, including but not limited to those related to convertible debt, stock-based compensation expense, accruals for research and development costs, the valuation of deferred tax assets, impairment of goodwill and intangible assets and impairment of long-lived assets. Management bases its estimates on historical experience and on various other assumptions 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 materially from those estimates.

Table of Contents

Segments

The Company operates and manages its business as one reportable operating segment, which is the business of developing a pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat acute and chronic bacterial infections using its proprietary bacteriophage-based technology. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for allocating resources and evaluating financial performance. The long-lived assets of $12.6 million, which represents 98.9% of the Company’s total long-lived assets, are maintained in the United States.

Concentration of Credit Risks and Certain Other Risks

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and restricted cash. As of December 31, 2023 and March 31, 2024, restricted cash was invested primarily in money market funds and U.S. treasury securities through highly rated financial institutions in accordance with the Company’s investment policy, to a concentration limit per issuer or sector.

Other receivables represent amounts due from the Medical Technology Enterprise Consortium (“MTEC”) (Note 13) and reimbursement for tenant improvements (Note 12).

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued 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”). ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The Company adopted this ASU as of January 1, 2024, which did not have an impact on its consolidated financial statements or related disclosures.

Recent Accounting Pronouncements Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU aligns the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company is currently evaluating the impact of adopting ASU 2023-06 on its consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC 280 on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements.

4. Fair Value Measurements

The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following three levels:

●Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date.

●Level 2: Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

●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.

The Company’s Convertible Loan (Note 7) is measured at fair value and remeasured at each measurement period, with changes in fair value recorded as other income (expense) in the consolidated statement of operations. The Company estimates the fair value of its Convertible Loan using a weighted probability model of various debt settlement scenarios during its term discounted to the reporting date. Conversion option scenarios are valued using option pricing models with assumptions and estimates such as volatility, expected term and risk-free interest rates. Level 3 fair value inputs include probability and timing of various settlement scenarios and selection of comparable companies.

The Company estimated the fair value of its convertible debt using the following inputs as of March 31, 2024 and December 31, 2023:



	March 31, 2024	December 31, 2023
Discount rate	23.75%	21.01%
Probabilities of settlement scenarios	0%-75%	0%-75%
Volatility	109.80%	123.3%
Expected term (in years)	0.3-0.8	0.2-1.0
Risk-free rate	5.05%-5.32%	4.66%-5.36%

The following table presents a summary of the changes in the fair value of the Company’s Level 3 financial liabilities (in thousands):


		Three months ended

7. Convertible Debt

On January 10, 2023, the Company received the Convertible Loan in the aggregate amount of $30.0 million from Innoviva pursuant to the Convertible Credit Agreement. The Convertible Loan bears interest at a rate of 8.0% per annum and was scheduled to mature on January 10, 2024. The Convertible Credit Agreement was amended on July 10, 2023, in connection with the Company’s entry into the 2023 Credit Agreement, to, among other changes, extend the maturity of the Convertible Loan to January 10, 2025. The Convertible Loan principal and accrued interest are payable at maturity. Repayment of the Convertible Loan is guaranteed by the Company’s domestic subsidiaries and foreign material subsidiaries, and the Convertible Loan is secured by substantially all of the assets of the Company and the subsidiary guarantors.

The Convertible Credit Agreement provides that if there is a financing from new investors of at least $30.0 million (a “Qualified Financing”), the outstanding principal amount of and all accrued and unpaid interest on the Convertible Loan shall be converted into shares of the Company’s Common Stock, at a price per share equal to a 15.0% discount to the lowest price per share for Common Stock paid by investors in such Qualified Financing. The Convertible Credit Agreement also required the Company to file a registration statement for the resale of all securities issued to the lender in connection with any conversion under the Convertible Credit Agreement, which the Company originally filed on February 13, 2023 and which was declared effective by the SEC on April 6, 2023. The Convertible Credit Agreement also confers upon the lender the option to convert any outstanding Convertible Loan amount, including all accrued and unpaid interest thereon, at the lender’s option, into shares of Common Stock at a price per share equal to the greater of book value or market value per share of Common Stock on the date immediately preceding the effective date of the Convertible Credit Agreement, which was $1.52 (as may be appropriately adjusted for any stock split, combination or similar act).

The Company evaluated authoritative guidance for accounting for the Convertible Loan and concluded that the Convertible Loan should be accounted for at fair value under ASC 480, Distinguish Liabilities from Equity, due to the fact that the Convertible Loan will predominately be settled with the Company’s Common Stock. Consequently, the Company recorded the Convertible Loan in its entirety at fair value on its condensed consolidated balance sheet, with changes in fair value recorded as other income (expenses) in the condensed consolidated statements of operations during each reporting period.

The Company recognized losses of $13.0 million and $3.2 million as the change in fair value of the Convertible Loan for the three months ended March 31, 2024 and March 31, 2023, respectively.

8. Long-Term Debt

On July 10, 2023, the Company entered into the 2023 Credit Agreement. The 2023 Credit Agreement provides for the 2023 Loan a secured term loan facility in an aggregate amount of $25.0 million at an interest rate of 14.0% per annum and has a maturity date of January 10, 2025. Principal and accrued interest are payable at maturity. Repayment of the 2023 Loan is guaranteed by the Company’s domestic subsidiaries, and the 2023 Loan is secured by substantially all of the assets of the Company and the subsidiary guarantors.

The 2023 Loan was initially recognized at fair value of $21.2 million and subsequently recognized at the amortized cost net of debt issuance costs and debt discount. Debt issuance costs and debt discount in the amounts of $0.1 million and $3.8 million, respectively, are amortized using the effective interest method to interest expense over the term of the 2023 Loan. The 2023 Loan’s annual effective interest rate was 27.31% as of March 31, 2024.

On March 4, 2024, the Company entered into the 2024 Credit Agreement. The 2024 Credit Agreement provides for the 2024 Loan a secured term loan facility in an aggregate amount of $35.0 million at an interest rate of 14.0% per annum and has a maturity date of June 4, 2025. Principal and accrued interest are payable at maturity. Repayment of the 2024 Loan is guaranteed by the Company’s domestic subsidiaries, and the 2024 Loan is secured by substantially all of the assets of the Company and the subsidiary guarantors.

Table of Contents

The 2024 Loan was initially recognized at cash proceeds of $35.0 million net of debt issuance costs of $0.1 million, and subsequently is recognized at the amortized cost. Debt issuance costs are amortized using the effective interest method to interest expense over the term of the 2024 Loan. The 2024 Loan’s annual effective interest rate was 14.25% for the three months ended March 31, 2024.

The 2023 Credit Agreement and the 2024 Credit Agreement contain customary affirmative and negative covenants and representations and warranties, including financial reporting obligations and certain limitations on indebtedness, liens, investments, distributions (including dividends), collateral, investments, mergers or acquisitions and fundamental corporate changes. The 2023 Credit Agreement and the 2024 Credit Agreement also include customary events of default, including payment defaults, breaches of provisions under the loan documents, certain losses or impairment of collateral and related security interests, the occurrence of certain events that could reasonably be expected to have a “material adverse effect” as set forth in the 2023 Credit Agreement and the 2024 Credit Agreement, certain bankruptcy or insolvency events, and a material deviation from the Company’s operating budget.

12. Commitments and Contingencies

Operating Leases

The Company leases office and research and development space under a non-cancelable operating lease in Marina del Rey, CA. The lease commenced on January 1, 2012 and was amended in April 2020 to, among other things, extend the lease term through December 31, 2031 (the “2020 Lease Amendment”). Annual base rent is from $1.9 million and increases by 3% annually and will be $2.5 million by the end of the amended term.

Concurrent with the Company’s execution of the 2020 Lease Amendment, an irrevocable letter of credit in the amount of $1.2 million was delivered to the landlord. Starting on February 1, 2022, and each year thereafter, the letter of credit will be reduced by 20% of the then outstanding amount. As of March 31, 2024, the letter of credit was $0.5 million.

On October 28, 2021, the Company entered into a lease for office and research and development space under a non-cancellable lease in Los Angeles, CA (the “2021 Lease”). The 2021 Lease payment start date was May 1, 2022 and the total lease term is for 16 years and runs through 2038. Monthly rent for 2022 and 2023 was fully or partially abated while the lessor and the Company completed planned tenant improvements to the facility. Base monthly rent is approximately $0.3 million in 2024. The Company is entitled to receive an allowance for tenant improvements of up to $7.3 million, of which the Company received $6.5 million as of March 31, 2024. The Company is responsible for construction costs over such allowance. Out-of-pocket expenses to be incurred by the Company are considered noncash lease payments, and included in the lease liability and right-of-use asset when the amount can be reasonably estimated.

In connection with the 2021 Lease, the Company delivered an irrevocable standby letter of credit in the amount of $5.0 million to the landlord in 2022.

Future minimum annual lease payments under the Company’s noncancelable operating leases as of March 31, 2024 are as follows (in thousands):

Legal Proceedings

From time to time, the Company may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of business. Any of these claims could subject the Company to costly legal expenses and, while management generally believes that there is adequate insurance to cover many different types of liabilities, the Company’s insurance carriers may deny coverage or policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on the Company’s consolidated results of operations and financial position. Additionally, any such claims, whether or not successful, could damage the Company’s reputation and business. The Company is currently not a party to any legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, would have a material adverse effect on our consolidated results of operations or financial position.

13. Grant and Awards

MTEC Grant

On June 15, 2020, the Company entered into a Research Project Award agreement (the “MTEC Agreement”) with MTEC, pursuant to which the Company received a $15.0 million grant and entered into a three-year program administered by the U.S. Department of Defense through MTEC managed by the Naval Medical Research Command with funding from the Defense Health Agency and Joint Warfighter Medical Research Program. On September 29, 2022, the MTEC Agreement was modified to increase the total award by $1.3 million to $16.3 million and extend the term into the third quarter of 2024. The MTEC funds are to partially fund a Phase 1b/2a, randomized, double-blind, placebo-controlled, dose escalation clinical study of the Company's therapeutic phage-based candidate, AP-SA02, for the treatment of complicated Staphylococcus aureus bacteremia infections. The MTEC Agreement specifies that the grant will be paid to the Company over the term of the award through a cost reimbursable model, based on agreed upon cost share percentages, and the grant money received is not refundable to MTEC.

Upon license or commercialization of intellectual property developed with the funding from the MTEC Agreement, additional fees will be due to MTEC. The Company will elect whether to (a) pay a fixed royalty amount, which is subject to a cap based upon total funding received, or (b) pay an additional assessment fee, which would also be subject to a cap based upon a percentage of total funding received.

Table of Contents

The MTEC Agreement is effective through October 30, 2024. The MTEC Agreement may be terminated in whole or in part, 30 calendar days following written notice from the Company to MTEC. In addition, MTEC has the right to terminate the MTEC Agreement upon material breach by the Company.

The Company determined that the MTEC Agreement is not in the scope of ASC 808 or ASC 606. Applying ASC 606 by analogy the Company recognizes proceeds received under the MTEC Agreement as grant revenue in the statement of operations when related costs are incurred. The Company recognized $1.0 million in grant revenue from the MTEC Agreement during the three months ended March 31, 2024. As of March 31, 2024, the Company recognized the entire $16.3 million award as grant revenue. The Company recognized $0.8 million in grant revenue from the MTEC Agreement during the three months ended March 31, 2023. As of March 31, 2024 and December 31, 2023, the Company had $1.0 million and $1.5 million as awards receivable from MTEC, respectively.

CFF Therapeutics Development Award

On March 13, 2020, the Company entered into an award agreement (the “Award Agreement”) with CFF, pursuant to which the Company received a Therapeutics Development Award of up to $5.0 million (the “CFF Award”). The CFF Award will be used to fund a portion of the Company’s Phase 1b/2a clinical trial of the Pseudomonas aeruginosa (“P. aeruginosa”) phage candidate, AP-PA02, as a treatment for Pseudomonas airway infections in people with cystic fibrosis (“CF”).

The first payment under the Award Agreement, in the amount of $1.0 million, became due upon signing the Award Agreement and was received in April 2020. The remainder of the CFF Award is payable to the Company incrementally in installments upon the achievement of certain milestones related to the development program and progress of the Phase 1b/2a clinical trial of AP-PA02, as set forth in the Award Agreement.

If the Company ceases to use commercially reasonable efforts directed to the development of AP-PA02, or any other Product (as defined in the Award Agreement), for a period of 360 days (an “Interruption”) and fails to resume the development of the Product after receiving from CFF notice of an Interruption, then the Company must either repay the amount of the CFF Award actually received by the Company, plus interest, or grant to CFF (1) an exclusive (even as to the Company), worldwide, perpetual, sublicensable license under technology developed under the Award Agreement that covers the Product for use in treating infections in CF patients (the “CF Field”), and (2) a non-exclusive, worldwide, perpetual, sublicensable license under certain background intellectual property covering the Product, to the extent necessary to commercialize the Product in the CF Field.

Upon commercialization by the Company of any Product, the Company will owe a fixed royalty amount to CFF, which is to be paid in installments determined, in part, based on commercial sales volumes of the Product. The Company will be obligated to make an additional fixed royalty payment upon achieving specified sales milestones. The Company may also be obligated to make a payment to CFF if the Company transfers, sells or licenses the Product in the CF Field, or if the Company enters into a change of control transaction.

The term of the Award Agreement commenced on March 10, 2020 and expires on the earlier of the date on which the Company has paid CFF all of the fixed royalty payments set forth therein, the effective date of any license granted to CFF following an Interruption, or upon earlier termination of the Award Agreement. Either CFF or the Company may terminate the Award Agreement for cause, which includes the Company’s material failure to achieve certain development milestones. The Company’s payment obligations survive the termination of the Award Agreement.

The Company concluded that the CFF Award is in the scope of ASC 808. Accordingly, as discussed in Note 3, the Company recognizes the award upon achievement of certain milestones as credits to research and development expenses. No credits to research and development expenses were recognized during the three months ended March 31, 2024 and 2023, respectively, related to the CFF Award. In addition, the Company concluded under the guidance in ASC 730 that it does not have an obligation to repay funds received once related research and development expenses are incurred

Overview

We are a clinical-stage biotechnology company focused on the development of pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections using our proprietary bacteriophage-based technology. We see bacteriophages as an alternative to antibiotics and an essential response to the growing bacterial resistance to current classes of antibiotics. Bacteriophages or “phages” have a powerful and highly differentiated mechanism of action that enables binding to and killing of targeted bacteria while uniquely preserving the normal human microbiome or “healthy bacteria”. This is in direct contrast to traditional broad-spectrum antibiotics which can alter the human microbiome increasing susceptibility to opportunistic pathogens, such as C. difficile. We believe that phages represent a promising means to effectively treat bacterial infections as an alternative to broad- spectrum antibiotics, especially for patients with bacterial infections resistant to current standard of care therapies, including the multidrug-resistant or “superbug” strains of bacteria. We are a leading developer of phage therapeutics and believe we are uniquely positioned to address the growing worldwide threat of antibiotic-resistant bacterial infections. We are completing two critical Phase 2 trials to ensure a pathway towards pivotal Phase 3 trials.

We are combining our proprietary approach and expertise in identifying, characterizing and developing both naturally occurring and engineered (synthetic) bacteriophages with our proprietary phage-specific host-engineered cGMP manufacturing capabilities to advance a target pipeline of high-quality bacteriophage product candidates for advanced development. We believe we are uniquely advancing two lead candidates to address both chronic and acute bacterial infections.

Table of Contents

Our first lead candidate focused primarily on chronic bacterial infections is the clinical phage candidate P. aeruginosa. On October 14, 2020, we received the approval to proceed from the U.S. Food and Drug Administration (the “FDA”) for our Investigational New Drug (“IND”) application for AP-PA02. In the first quarter of 2023, we announced positive topline results from the completed “SWARM-P.a.” study – a Phase 1b/2a, multicenter, double-blind, randomized, placebo-controlled, single ascending dose and multiple ascending dose clinical trial to evaluate the safety and tolerability of inhaled AP-PA02 in subjects with cystic fibrosis and chronic pulmonary P. aeruginosa infection. Data indicate that AP-PA02 was well-tolerated with a treatment emergent adverse event profile similar to placebo. Pharmacokinetics findings confirm AP-PA02 can be effectively delivered to the lungs through nebulization with minimal systemic exposure, with single ascending doses and multiple ascending doses resulting in a proportional increase in exposure as measured in induced sputum. AP-PA02 exposures were generally consistent across patient subjects. Additionally, bacterial levels of P. aeruginosa in the sputum measured at several timepoints suggest improvement in bacterial load reduction for subjects treated with AP-PA02 at the end of treatment as compared to placebo after ten days of dosing. In addition, a correlation was seen between increasing phage dose (higher AP-PA02 exposures) and reduction in the bacterial load, supporting the biologic plausibility of a bacterial specific mechanism of action and creating the opportunity for phage as a therapeutic alternative to inhaled antibiotics. This study was supported by the Cystic Fibrosis Foundation, which granted us a Therapeutics Development Award of $5.0 million. As of March 31, 2024, we received the full award’s amount, including the final payment of $0.3 million in January 2024. Following the promising Phase 1b/2a results of favorable safety and tolerability profile and plausible mechanism of action, an additional confirmatory Phase 2 trial was initiated in non-cystic fibrosis Bronchiectasis (“NCFB”) patients with similar chronic pulmonary infections due to P. aeruginosa.

On February 22, 2022, we announced FDA approval to proceed with our IND application for AP-PA02, in a second indication, NCFB. We initiated a Phase 2 trial (“Tailwind”) in NCFB in 2022 and reported first patient dosing in the first quarter of 2023. The “Tailwind” study is a Phase 2, multicenter, double-blind, randomized, placebo-controlled study to evaluate the safety, phage kinetics, and efficacy of inhaled AP-PA02 phage therapeutic in subjects with NCFB and chronic pulmonary P. aeruginosa infection. The trial design includes two cohorts. One cohort enrolls subjects not on chronic inhaled antibiotics, randomized to receive either inhaled AP-PA02 or placebo. The other cohort enrolls subjects on chronic inhaled antibiotics, randomized to receive either inhaled AP-PA02 plus their chronic inhaled antibiotic or placebo plus their chronic inhaled antibiotic. This study will analyze AP-PA02 as monotherapy as well as AP-PA02 in combination with inhaled antibiotics. We are actively accelerating enrollment (currently approximately 70% enrolled) at increased AP-PA02 dose levels, and potentially extending duration of therapy, as allowed with the current protocol design. The aim of the study is to define a safe dose and dosing duration with promising biologic correlation in anticipation for a definitive Phase 3 trial in 2025. We plan to evaluate inhaled AP-PA02 as an alternative to inhaled antibiotics in chronic pulmonary P. aeruginosa infections in subjects with NCFB. As there are no FDA approved anti-infective treatments for NCFB, a definitive pivotal placebo-controlled trial is plausible, providing a pathway to commercialization, pending positive results.

In parallel, we have an acute bacterial infection clinical development plan focused on Staphylococcus aureus (“S. aureus”) bacteremia, a difficult-to-treat and often life-threatening human infections that can result in high morbidity and mortality and for which bacterial resistance to antibiotics is growing.

A key advantage of our phage manufacturing expertise is the purity profiles of our phage products, including AP-SA02, our phage product candidate for S. aureus; this has enabled us to pursue treatment of complicated S. aureus bacteremia, where repetitive intravenous dosing is required. On June 15, 2020, we entered into an agreement (the “MTEC Agreement”) with the Medical Technology Enterprise Consortium (“MTEC”), pursuant to which we expect to receive a $15.0 million grant and entered into a three-year program administered by the U.S Department of Defense through MTEC with funding from the Defense Health Agency and Joint Warfighter Medical Research Program. On September 29, 2022, the MTEC Agreement was modified to increase the total award by $1.3 million to $16.3 million and extend the term into the second half of 2024. The grant is being used to partially fund a Phase 1/2, multi-center, randomized, double-blind, placebo- controlled dose escalation study that will assess the safety, tolerability, and efficacy of our phage-based candidate, AP-SA02, for the treatment of adults with S. aureus bacteremia.

On November 17, 2021, we announced that we had received from the FDA the approval to proceed for our IND application for AP-SA02. We are focused on accelerating enrollment of the Phase 2a segment of the “diSArm” study,

Table of Contents

evaluating safety with higher intravenous doses, which is possible due to the high purity of our phage product candidates. Currently the trial is over 50% enrolled. We are committed to developing a definitive efficacy trial in 2025 focused on phage as an alternative to broad-spectrum antibiotics and/or antibiotic sparing to decrease the utilization of broad-spectrum antibiotics and their detrimental impact on the normal human microbiome.

On August 1, 2022, we announced FDA approval to proceed with our IND application for AP-SA02, in a second indication, prosthetic joint infections (“PJI”) with S. aureus. We had planned to initiate a Phase 1b/2a trial in 2023; however in light of the growing concerns of both PJI and wound infection, we are revising the protocol to include both indications. Driven by data from the bacteremia study, and with sufficient funding, we may in the future initiate a Phase 1b/2a trial to assess the safety and tolerability of intravenous and intra-articular AP-SA02 as an adjunct to standard of care antibiotics in adults undergoing treatment of periprosthetic joint infections and/or wound infections caused by S. aureus.

We remain committed to conducting randomized controlled clinical trials required for FDA approval in order to move toward the commercialization of our phage products as alternatives to traditional antibiotics, providing a potential method of treating patients suffering from drug-resistant and difficult-to-treat bacterial infections.

The following chart summarizes the status of our phage product candidate development programs and partners.

We have incurred net losses since our inception and our operations to date have been primarily limited to research and development and raising capital. As of March 31, 2024, we had an accumulated deficit of $333.8 million. We currently expect to use our existing cash for the focused research and development of our current product candidates and for working capital and other general corporate purposes. We anticipate that a substantial portion of our capital resources and efforts in the foreseeable future will be focused on completing the development and seeking to obtain regulatory approval of our product candidates. We do not expect to generate product revenue unless and until we successfully complete development and obtain marketing approval for at least one of our product candidates. We may also use a portion of our existing cash for the potential acquisition of, or investment in, product candidates, technologies, formulations or companies that complement our business, although we have no current understandings, commitments or agreements to do so.

Our existing cash of $37.9 million as of March 31, 2024 will not be sufficient to enable us to complete all necessary development of any potential product candidates. Accordingly, we will be required to obtain further funding through one or more other public or private equity offerings, debt financings, collaboration, strategic financing, grants or government contract awards, licensing arrangements or other sources. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and potential disruptions to, and volatility in, financial markets in the United States and worldwide. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on acceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of our development programs or other operations, dispose of assets, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologies or potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financial condition and results of operations and result in a loss of investment by our stockholders.

Total research and development expense:	$	8,016	$	9,604	$	(1,588)		(16.5%)

Research and development expenses decreased by $1.6 million, from $9.6 million for the three months ended March 31, 2023 to $8.0 million for the three months ended March 31, 2024.

Clinical trial costs decreased by $0.8 million, from $2.5 million for the three months ended March 31, 2023, to $1.7 million for the three months ended March 31, 2024. The decrease is primarily due to a decrease in AP-PA02 Cystic Fibrosis study costs of $0.7 million as this study was completed during 2024; a decrease in AP-SA02 Bacteremia study costs of $0.7 million due to a credit of $0.8 million received from a clinical research organization for prior incurred costs as we negotiated an amended statement of work with the clinical research organization in March 2024; and a decrease in AP-SA02 Prosthetic Joint Infection study costs of $0.2 million as this work was completed during 2024 year, partially offset by an increase in AP-PA02 Non-Cystic Fibrosis Bronchiectasis study clinical related costs of $0.9 million.

Other external research and development costs decreased by $0.3 million from $1.2 million for the three months ended March 31, 2023, to $0.9 million for the three months ended March 31, 2024. The change is a result of a decrease of $0.2 million in laboratory supplies purchases and a decrease of $0.1 million in research and development consulting services.

Our expenses by product and by project for the three months ended March 31, 2024 and 2023 were as follows:

Personnel-related costs, including employee payroll and related expenses, decreased by $0.7 million, from $3.3 million for the three months ended March 31, 2023 to $2.6 million for the three months ended March 31, 2024, largely as a result of lower salaries and wage expenses in our research and development organization in the three months ended

March 31, 2024, compared to the three months ended March 31, 2023, as well as employee stock-based compensation expenses decrease of $0.5 million, which was primarily due to the full vesting of awards issued in prior periods.

Facilities and overheads increased in the three months ended March 31, 2024 compared to the 2023 period by $0.3 million. The main factor driving the increase is related to expenses related to our operating leases.

General and Administrative

General and administrative expenses were $3.2 million and $2.6 million for the three months ended March 31, 2024 and 2023, respectively. The increase of $0.6 million is primarily related to an increase of $ 0.3 million in legal, accounting and other consulting expenses, an increase of $0.1 million in lease expenses, and an increase in other facilities and overhead expenses of $0.2 million.

Interest Income

Interest income for the three months ended March 31, 2024, and 2023 was less than $0.1 million, and related to interest income on our cash balances.

Interest Expense

We recognized interest expense for the three months ended March 31, 2024, of $1.8 million related to the interest expenses and the amortization of debt discount and issuance costs for the 2023 Loan and 2024 Loan received from Innoviva in July 2023 and March 2024, respectively. Interest expense is accrued and is payable at the maturity of the 2023 Loan and the 2024 Loan in 2025.

Change in Fair Value of Convertible Debt

We recognized a loss on change in the fair value of the Convertible Loan for the three months ended March 31, 2024, and 2023 of $13.2 million and $3.2 million, respectively. The Convertible Loan received from Innoviva in January 2023 and amended in July 2023 is accounted at fair value using a weighted probability of various settlement scenarios of the Convertible Loan during its term discounted to each reporting date. Conversion option scenarios are valued using an option pricing model with significant assumptions and estimates such as volatility, expected term and risk-free interest rates.

Liquidity, Capital Resources and Financial Condition

We have incurred net losses since our inception and have negative operating cash flows. Our cash of $37.9 million as of March 31, 2024, will not be sufficient to fund our operations for the next 12 months from the date of issuance of our condensed consolidated financial statements for the three months ended March 31, 2024. We plan to control our expenses and to raise additional capital through a combination of public and private equity, debt financings, strategic alliances, and grant arrangements. These circumstances raise substantial doubt about our ability to continue as a going concern. While management believes this plan to raise additional funds will alleviate the conditions that raise substantial doubt, these plans are not entirely within its control and cannot be assessed as being probable of occurring. We may not be able to secure additional financing in a timely manner or on favorable terms, if at all.

During the year ended December 31, 2023, we received the convertible Loan in the aggregate amount of $30.0 million and the 2023 Loan in the aggregate amount of $25.0 million from Innoviva. The Convertible Loan and the 2023 Loan mature in January 2025, and principal and accrued interest are payable at maturity. The Convertible Loan provides for various conversion and repayment options, including the conversion of principal and accrued interest into shares of our Common Stock upon a Qualified Financing and the Company’s option to repay the Convertible Loan prior to maturity.

On March 4, 2024, we entered into the 2024 Credit Agreement for the 2024 Loan in an aggregate amount of $35.0 million with Innoviva. Concurrently with the execution of the 2024 Loan, we amended certain provisions of the

Convertible Credit Agreement and the 2023 Credit Agreement to, among other things, conform certain terms relating to permitted indebtedness and permitted liens. The 2024 Loan bears 14% annual interest rate and matures in June 2025. Principal and accrued interest are payable at maturity.

Future Capital Requirements

We will need to raise additional capital in the future to continue to fund our operations. Our future funding requirements will depend on many factors, including:

●

the costs and timing of our research and development activities;

●

the progress and cost of our clinical trials and other research and development activities;

●

manufacturing costs associated with our targeted phage therapies strategy and other research and development activities;

●

the costs of completing the construction and improvements of our leased premises to be used as our new headquarters. We expect to incur $3.0 million of additional expenses by mid-2024, which may increase or decrease as we complete the construction by mid-2024;

●

the costs and timing of seeking regulatory approvals;

●

the costs of filing, prosecuting and enforcing any patent applications, claims, patents and other intellectual property rights; and;

●

the costs of potential lawsuits involving us or our product candidates.

We may seek to raise capital through a variety of sources, including:

●

the public equity market;

●

private equity financings;

●

collaborative arrangements;

●

government grants; or

●

strategic financing.

Any additional fundraising efforts may divert our management team from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. Our ability to raise additional funds will depend, in part, on the success of our product development activities, including our targeted phage therapies strategy and any clinical trials we initiate, regulatory events, our ability to identify and enter into in-licensing or other strategic arrangements, and other events or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyond our control. We cannot be certain that sufficient funds will be available to us when required or on acceptable terms. If we are unable to secure additional funds on a timely basis or on acceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of our development programs or other operations, dispose of technology or assets, pursue an acquisition of our company by a third party at a price that may result in a loss on investment for our stockholders, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologies or potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financial condition and results of operations, increase the risk of insolvency and loss of investment by our stockholders. To the extent that additional capital is raised through the sale of equity or

convertible debt securities, the issuance of such securities could result in dilution to our existing stockholders. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, financial markets in the United States and worldwide.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate estimates and assumptions, including but not limited to those related to convertible debt, stock-based compensation expense, accruals for research and development costs, lease assets and liabilities, the valuation of deferred tax assets, valuation of uncertain income tax positions, impairment of goodwill and intangible assets and impairment of long-lived assets. We base our estimates on historical experience and on various other assumptions 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.

Refer to Note 3 to the consolidated financial statements and critical accounting policies and estimated included in our Form 10-K filed with the SEC on March 21, 2024. There were no material changes to our critical accounting policies from December 31, 2023.
