Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing in this Annual Report on Form 10-K. This discussion and other parts of this Annual Report on Form 10-K contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, 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.

Objective

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide information necessary to understand our audited consolidated financial statements for the two-year period ended December 31, 2024 and highlight certain other information which, in the opinion of management, will enhance a reader’s understanding of our financial condition, changes in financial condition, results of operations, and cash flows. In particular, the discussion is intended to provide an analysis of significant trends and material changes in our financial position and the operating results of our business during the year ended December 31, 2024, as compared to the year ended December 31, 2023. This discussion should be read in conjunction with our consolidated financial statements for the two-year period ended the year ended December 31, 2024 and related notes included elsewhere in this Annual Report on Form 10-K.

Overview

We are a biopharmaceutical company focused on the development, manufacture, and commercialization of products that address unmet patient needs, with current focus directed towards rare cardiopulmonary diseases such as PAH and PH-ILD. We operate through our wholly owned operating subsidiaries, Liquidia Technologies and Liquidia PAH, formerly known as RareGen.

We currently generate revenue pursuant to the Promotion Agreement between Liquidia PAH and Sandoz, dated as of August 1, 2018, as amended, sharing profit derived from the sale of Sandoz’s Treprostinil Injection in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. We employ a targeted sales force calling on physicians and hospital pharmacies involved in the treatment of PAH and PH-ILD in the United States, as well as key stakeholders involved in the distribution and reimbursement of medicines to treat these patients. We established our commercial presence in the field to support Treprostinil Injection and have since expanded our presence to support the potential launch of YUTREPIA, further validating our reputation as a company committed to supporting PAH and PH-ILD patients.

We conduct research, development and manufacturing of novel products by applying our subject matter expertise in cardiopulmonary diseases and our proprietary PRINT® technology, a particle engineering platform, to enable precise production of uniform drug particles designed to improve the safety, efficacy and performance of a wide range of therapies. Through development of our own products and research with third parties, we have experience applying PRINT across multiple routes of administration and drug payloads including inhaled therapies, vaccines, biologics, nucleic acids and ophthalmic implants, among others.

Our lead product candidate is YUTREPIA for the treatment of PAH and PH-ILD. YUTREPIA is an inhaled dry powder formulation of treprostinil designed with PRINT to improve the therapeutic profile of treprostinil by enhancing deep lung delivery while using a convenient, low effort DPI and by achieving higher dose levels than the labeled doses of current inhaled therapies. On August 16, 2024, the FDA (i) granted tentative approval for our NDA for YUTREPIA for the treatment of PAH and PH-ILD and (ii) simultaneously determined that Tyvaso DPI, approved on May 23, 2022, qualifies for a three-year New Clinical Investigation exclusivity for the chronic use of dry powder formulations of

85

Table of Contents

treprostinil for the approved indications. As a result, final approval of YUTREPIA for PAH and PH-ILD is delayed until after expiry of the three-year regulatory exclusivity for Tyvaso DPI on May 23, 2025.

We are also developing L606, an investigational, liposomal formulation of treprostinil administered twice-daily with a short-duration next-generation nebulizer, which we licensed from Pharmosa. L606 is currently being evaluated in an open-label study in the United States for treatment of PAH and PH-ILD with a planned pivotal study for the treatment of PH-ILD.

Since inception, we have incurred significant operating losses. Our net loss was $130.4 million and $78.5 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, we had an accumulated deficit of $559.5 million. We expect to incur significant expenses and operating losses for the foreseeable future as we advance our product candidates through clinical trials, seek regulatory approval of such product candidates and pursue commercialization of any approved product candidates. These efforts require significant amounts of capital, adequate personnel and infrastructure, and extensive compliance-reporting capabilities. Even if our development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales. Additionally, our HCR Agreement contains fixed quarterly payments and minimum cash covenants that require us to maintain cash and cash equivalents in an amount at least equal to $15.0 million for the remainder of the payment term, which is expected to conclude in 2031.

Our future funding requirements will be heavily determined by the timing of the potential commercialization of YUTREPIA and the resources needed to support development of our product candidates. Based on current operating plans and excluding any external financing, we will not have sufficient cash and cash equivalents to fund operating expenses and capital requirements and meet our minimum cash covenants beyond one year from the issuance of these consolidated financial statements, and therefore, we have concluded that there is substantial doubt about its ability to continue as a going concern. Accordingly, we will require additional funding over the next twelve months to continue our operations and maintain compliance with debt covenants, and could be required to delay, reduce, or eliminate research and development programs, product portfolio expansion, or commercialization efforts, which could adversely affect our business prospects, or potentially force us to cease operations.

Recent Event

On March 17, 2025, we entered into the Sixth Amendment to the HCR Agreement pursuant to which HCR made an additional $100.0 million available for funding under the second tranche. An additional $25.0 million from the second tranche was funded on March 17, 2025. An additional $50.0 million may be funded upon the first commercial sale of YUTREPIA following receipt of final FDA approval for the treatment of PAH and PH-ILD, so long as no injunction has been issued prohibiting Liquidia from commercializing YUTREPIA for either or both of PAH and PH-ILD, and an addition $25.0 million upon the mutual agreement of the parties after achieving aggregate net sales of YUTREPIA in excess of $100 million at any time on or prior to June 30, 2026. As consideration for the additional $25.0 million funded at closing, Liquidia has agreed to a fixed payment schedule that terminates in 2032. Payments on the last two tranches, when funded, would also follow a fixed payment schedule. As further discussed in Note 13 “Long-term debt” to the accompanying financial statements, aggregate payments to HCR are capped at 175% of the total amounts advanced by under the HCR Agreement plus a potential true-up payment to be made by us if HCR’s internal rate of return is less than a minimum rate of return on the date the cap is reached. The minimum rates of return for the three new tranches are 16%, 13% and 12%, respectively.

Components of Statements of Operations

Revenue

We primarily generate revenue pursuant to the Promotion Agreement, under which we receive a 50% share in the profit derived from the sale of Treprostinil Injection in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. To administer Treprostinil Injection through subcutaneous injection, patients currently must use the CADD-MS 3 infusion pump manufactured by ICU Medical. ICU Medical no longer manufactures or supports the CADD-MS 3 infusion pump. Although we believe that

86

Table of Contents

the number of available CADD-MS 3 infusion pumps will be sufficient to serve patients through at least the end of 2025, it is possible that the availability of CADD-MS 3 infusion pumps could end earlier. Due to this limitation in the availability of pumps, specialty pharmacies will limit the number of patients that they place on subcutaneous Treprostinil Injection therapy in order to ensure that patients placed on subcutaneous administration of Treprostinil Injection will not have to discontinue such treatment due to the unavailability of CADD-MS infusion pumps. Until we are able to obtain a pump to replace the CADD-MS 3 infusion pump, the number of patients that can receive subcutaneous administration of Treprostinil Injection will continue to be constrained. Revenue will continue to be impacted or at risk until alternative pumps are available.

Cost of Revenue

Cost of revenue consists of (i) an allocation of the cost of our sales force associated with calling on physicians and hospital pharmacies involved in the treatment of PAH with Treprostinil Injection, as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection and (ii) amortization of the intangible asset associated with the Promotion Agreement. We amortize the intangible asset associated with the Promotion Agreement in a manner consistent with our recognition of the related revenue.

Research and Development Expenses

Research and development expenses consist of expenses incurred in connection with the development of our product candidates. We expense research and development costs as incurred. These expenses include:

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. In the near term we expect that our research and development expenses to increase as we complete manufacturing activities, conduct existing clinical trials, and initiate potential clinical trials. However, levels of research and development spending are highly dependent upon the selection and progression of product candidates. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if ever, material net cash inflows may commence from any of our product candidates. This uncertainty is due to the numerous risks and

87

Table of Contents

uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals. We may never succeed in achieving regulatory approval for any of our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, or our ability to manufacture and supply product, we could be required to expend significant additional financial resources and time on the completion of clinical development. Drug commercialization can take several years and millions of dollars in development costs.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance and legal functions, including stock-based compensation. Other general and administrative expenses include facility-related costs, patent filing and prosecution costs and professional fees for marketing, legal, auditing and tax services and insurance costs.

Other Income (Expense)

Other income (expense) is comprised of interest income and expense and loss on extinguishment of debt. Interest income consists of interest earned on our cash equivalents. Interest expense consists of interest charges on finance leases and long-term debt. These charges include monthly recurring interest on such obligations in addition to interest accretion and amortization of debt discounts and issuance costs to interest expense.

Comparison of the Years Ended December 31, 2024 and 2023

The following table summarizes our results of operations:

​

​

Revenue

Revenue was $14.0 million for the year ended December 31, 2024, compared to $17.5 million for the year ended December 31, 2023. Revenue related primarily to the Promotion Agreement. The decrease of $3.5 million was primarily due to lower sales quantities, driven by limitations on the availability of pumps used to administer Treprostinil Injection subcutaneously. Sales quantities will continue to be impacted or at risk until alternative pumps are available.

Cost of Revenue

Cost of revenue was $5.9 million for the year ended December 31, 2024, compared to $2.9 million for the year ended December 31, 2023. Cost of revenue related to the Promotion Agreement as noted above. The increase from the prior year was primarily due to our sales force expansion during the fourth quarter of 2023.

Research and Development Expenses

Research and development expenses were $47.8 million for the year ended December 31, 2024 compared to $43.2 million for the year ended December 31, 2023. The increase of $4.6 million or 11% was primarily due to (i) a $6.1 million increase in expenses related to our L606 program, (ii) a $5.3 million increase in expenses related to YUTREPIA research and development activities, including the ASCENT trial, (iii) a $5.1 million increase in personnel expenses (including stock-based compensation) related to increased headcount, and (iv) a $3.5 million upfront license fee due to Pharmosa for the exclusive license in Europe to develop and commercialize L606 recorded during the year ended December 31, 2024, offset by (i) $5.1 million lower commercial manufacturing expenses reflecting the impact of expensing YUTREPIA inventory costs in the prior year and (ii) a $10.0 million upfront license fee due to Pharmosa for the exclusive license in North America to develop and commercialize L606 recorded during the year ended December 31, 2023.

General and Administrative Expenses

General and administrative expenses were $81.6 million for the year ended December 31, 2024, compared to $44.7 million for the year ended December 31, 2023. The increase of $36.9 million or 82% was primarily due to (i) a $19.7 million increase in personnel expenses (including stock-based compensation) driven by higher headcount and expansion of our sales force in the fourth quarter of 2023, (ii) a $7.9 million increase in legal fees related to our ongoing

89

Table of Contents

YUTREPIA-related litigation, and (iii) a $6.8 million increase in commercial expenses in preparation for the potential commercialization of YUTREPIA.

Other Income (Expense)

Total other expense, net was $9.1 million for the year ended December 31, 2024, compared to $5.1 million for the year ended December 31, 2023. The increase of $4.0 million was primarily driven by a $2.0 million increase in the net loss on extinguishment of debt resulting from the Fourth and Fifth Amendments to the HCR Agreement, which were executed in January 2024 and September 2024, respectively. Additionally, there was a $6.2 million increase in interest expense attributable to the higher borrowings under the HCR Agreement compared to the prior year and a $4.2 million increase in interest income attributable to higher money market balances.

Liquidity and Capital Resources

Sources of Liquidity

We have financed our growth and operations through a combination of funds generated from revenues, the issuance of convertible preferred stock and common stock, bank borrowings, the issuance of convertible notes, and other long-term debt. Our principal uses of cash have been for working capital requirements and capital expenditures. As of December 31, 2024, we had cash and cash equivalents of $176.5 million, stockholders’ equity of $77.3 million, and an accumulated deficit of $559.5 million.

In September 2024, we sold 6,460,674 shares of our common stock in an underwritten registered public offering at an offering price of $8.90 per share (the “2024 Offering”) for gross proceeds of approximately $57.5 million, before deducting offering costs of approximately $3.8 million.

A fund affiliated with Paul B. Manning, a member of our Board of Directors, participated in the 2024 Offering and purchased shares of common stock in an aggregate amount of approximately $3.0 million at the public offering price per share and on the same terms as the other purchasers in the 2024 Offering.

Concurrently with the 2024 Offering referenced above, we entered into a common stock purchase agreement with funds managed by Caligan Partners LP (“Caligan”), our largest stockholder, for the sale by us in a private placement of an aggregate of 1,123,595 shares of our common stock at a purchase price of $8.90 per share for gross and net proceeds of approximately $10.0 million (the “Caligan 2024 Private Placement”).

In January 2024, we sold 7,182,532 shares of our common stock in a private placement (the “2024 Private Placement”) at a purchase price of $10.442 per share for gross proceeds of approximately $75.0 million, before deducting offering expenses of less than $0.1 million.

In December 2023, we sold 3,491,620 shares of our common stock in an underwritten registered public offering at an offering price of $7.16 per share for gross proceeds of approximately $25.0 million, before deducting offering costs of approximately $1.9 million.

In December 2023, we also entered into a common stock purchase agreement with Roger Jeffs, our Chief Executive Officer, for the sale by us in a private placement of an aggregate of 139,665 shares of our common stock at a purchase price of $7.16 per share for gross proceeds of approximately $1.0 million.

In January 2023, we entered into the HCR Agreement, pursuant to which HCR has paid us an aggregate investment amount of $100.0 million (the “Investment Amount”). $32.5 million of the Investment Amount was funded on January 27, 2023, $22.2 million of which was used to satisfy in full and retire our previously outstanding debt with Silicon Valley Bank. An additional $10.0 million of the Investment Amount was funded on July 27, 2023, which was used to fund payment of the $10.0 million upfront license fee due under the Pharmosa License Agreement. On January 5, 2024 and September 12, 2024 an additional $25.0 million and $32.5 million of the Investment Amount was funded, respectively. On March 17, 2025, we entered into the Sixth Amendment to the HCR Agreement pursuant to which HCR

90

Table of Contents

made an additional $100.0 million available for funding under the second tranche, $25.0 million of which was funded on March 17, 2025. See Note 13 “Long-term debt” to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

Future Funding Requirements

Prior to the potential FDA approval of YUTREPIA and until such time as we can generate significant revenues from its sale, if ever, we anticipate we will incur net operating losses and negative cash flows from operations. We plan to focus in the near-term on preparations for the potential commercial launch of YUTREPIA, continuing promotion of Treprostinil Injection, investing in research and development efforts for our YUTREPIA and L606 programs, and expanding our corporate infrastructure. We may not be able to complete the development and initiate commercialization of these programs if, among other things, our clinical trials are not successful or if the FDA does not approve our product candidates when we expect, or at all.

Our primary uses of capital are, and we expect will continue to be, compensation and related personnel expenses, clinical costs, manufacturing process development costs, external research and development services, laboratory and related supplies, regulatory expenses, legal costs, administrative and overhead costs and repayments under the HCR Agreement. We also expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution as we prepare to potentially receive regulatory approval for YUTREPIA.

Our future funding requirements will be heavily determined by the timing of the potential commercialization of YUTREPIA and the resources needed to support development of our product candidates. Based on current operating plans and excluding any external financing, we will not have sufficient cash and cash equivalents to fund operating expenses and capital requirements and meet our minimum cash covenants beyond one year from the issuance of these consolidated financial statements, and therefore, we have concluded that there is substantial doubt about its ability to continue as a going concern. Accordingly, we will require additional funding over the next twelve months to continue our operations and maintain compliance with debt covenants, and could be required to delay, reduce, or eliminate research and development programs, product portfolio expansion, or commercialization efforts, which could adversely affect our business prospects, or potentially force us to cease operations. See Note 1 to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K for information regarding our ability to continue as a going concern.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceuticals, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

91

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Cash Flows

The following table summarizes our sources and uses of cash and cash equivalents:

​

​

Operating Activities

Net cash used in operating activities increased $51.8 million to $93.4 million for the year ended December 31, 2024, from $41.6 million for the year ended December 31, 2023. The increase was primarily due to $41.2 million higher net loss adjusted for non-cash items and unfavorable working capital changes of $10.7 million.

Investing Activities

Net cash used in investing activities was $8.4 million for the year ended December 31, 2024 compared to $11.3 million for the year ended December 31, 2023. During the year ended December 31, 2024, we made $4.9 million in property, plant and equipment purchases and a $3.5 million upfront license fee payment to Pharmosa for the exclusive license in Europe to develop and commercialize L606. During the year ended December 31, 2023, we made a $10.0 million upfront license fee payment to Pharmosa for the exclusive license in North America to develop and commercialize L606 and paid $1.3 million for property, plant and equipment purchases.

Financing activities

Net cash provided by financing activities was $194.7 million during the year ended December 31, 2024 compared to $43.2 million provided by financing activities the year ended December 31, 2023. During the year ended December 31, 2024, we received $138.6 million net proceeds from the sale of common stock primarily relating to the 2024 Offering and 2024 Private Placement, $57.5 million net proceeds from the HCR Agreement, and $3.0 million from the issuance of common stock under stock incentive plans. These inflows were offset by $4.9 million in payments under the HCR Agreement. During the year ended December 31, 2023, we received $41.7 million net proceeds from the HCR Agreement of which $22.2 million was used to repay existing indebtedness with Silicon Valley Bank, $24.2 million aggregate net proceeds from the sale of common stock in a public offering and a public private placement, and $1.2 million from the issuance of common stock under stock incentive plans. These inflows were offset by $1.7 million in payments under the HCR Agreement.

Contractual Obligations and Commitments

Milestone and Royalty Obligations

Under the UNC License Agreement, the Company is obligated to pay UNC royalties equal to a low single digit percentage of all net sales of drug products whose manufacture, use or sale includes any use of the technology or patent rights covered by the UNC License Agreement, including YUTREPIA.

In March 2012, we entered into an agreement, as amended, with Chasm Technologies, Inc. for manufacturing consulting services related to our manufacturing capabilities during the term of the agreement. We agreed to pay future contingent

92

Table of Contents

milestones and royalties, totaling no more than $1.5 million, $0.2 million of which was accrued as of December 31, 2024.

In December 2022, we entered into a Pump Development Agreement with Mainbridge and Sandoz. The Pump Development Agreement provides for the cooperation between us, Sandoz and Mainbridge to develop a new pump that is suitable for the subcutaneous administration of Treprostinil Injection. Mainbridge will perform development, validation and testing activities required for the pump and related consumables in anticipation of submitting a 510(k) clearance application for the pump to the FDA. In connection with the Pump Development Agreement, we and Sandoz have agreed to pay Mainbridge certain future contingent milestone payments in accordance with the terms and conditions set forth therein.

In June 2023, we entered into a License Agreement with Pharmosa pursuant to which we were granted an exclusive license in North America to develop and commercialize L606, an inhaled, sustained-release liposomal formulation of treprostinil currently being evaluated in a clinical trial for the treatment of PAH and PH-ILD. In October 2024, we and Pharmosa amended the agreement to expand our licensed territory to include key markets in Europe, Japan and elsewhere, in addition to licensing proprietary nebulizers controlled by Pharmosa and being evaluated for use in a planned global pivotal study for the treatment of PH-ILD. In consideration for these exclusive rights, we will pay Pharmosa potential development milestone payments tied to clinical development and approvals in PAH and/or PH-ILD of up to $37.75 million, potential sales milestones of up to $185 million in North America and $150 million outside North American and two tiers of low, double-digit royalties on net sales of L606. Pharmosa will also receive a $10 million milestone payment for each additional indication approved by the FDA after PAH and PH-ILD and each additional product approved by the FDA under the license, a $2 million milestone payment for each additional indication approved by the EMA after PAH and PH-ILD, and a $0.5 million milestone payment for each additional indication approved by the PMDA after PAH and PH-ILD.

Purchase Obligations

We enter into contracts in the normal course of business with contract third-party service providers to assist in the performance of research and development and manufacturing activities. Subject to required notice periods and obligations under binding purchase orders, we can elect to discontinue the work under these agreements at any time.

On July 14, 2023, we entered into an Amended and Restated Commercial Manufacturing Services and Supply Agreement with Lonza, which was amended on January 7, 2025 (collectively, the “CSA”). Pursuant to the terms of the CSA, we deliver bulk treprostinil powder, manufactured using our proprietary PRINT® technology, and Lonza encapsulates and packages it. The CSA was effective upon signing and will be in effect until December 31, 2028 and may thereafter be extended upon the mutual written agreement of the parties in accordance with the terms of the CSA. We may terminate the CSA upon 60 days’ written notice to Lonza in the event that the application for regulatory approval of YUTREPIA is rejected by the FDA and such FDA decision is not caused by the fault of the Company (the “Termination for FDA Rejection”). Lonza may terminate the CSA upon 120 days written notice if we do not receive regulatory approval of YUTREPIA from the FDA by December 31, 2025 (the “Termination for FDA Delay”). Upon any Termination for FDA Rejection or Termination for FDA Delay, we would reimburse Lonza for 50% of its documented out-of-pocket expenditures for any capital equipment that is purchased by Lonza after the effective date of the Agreement to perform the services for us, not to exceed $2.5 million in the aggregate. We are required to provide Lonza with quarterly forecasts of our expected production requirements for the following 24-month period, the first twelve months of which is considered a binding, firm order. We are required to purchase certain minimum annual order quantities, which may be adjusted by us after the thirteenth month after receipt of regulatory approval of YUTREPIA. The CSA provides for tiered pricing depending upon the batch size ordered.

In addition, on January 10, 2020, we entered into a multi-year supply agreement with LGM to supply active pharmaceutical ingredients for YUTREPIA. Under the supply agreement with LGM, we are required to provide rolling forecasts, a portion of which will be considered a binding, firm order, subject to an annual minimum purchase commitment of $2.7 million for the term of the agreement. The agreement expires five years from the first marketing authorization approval of YUTREPIA.

93

Table of Contents

As of December 31, 2024, we have non-cancelable commitments for product manufacturing and supply costs of approximately $12.8 million.

Lease Obligations

We have operating lease obligations including rental amounts due on leases of certain laboratory, manufacturing and office space and equipment under the terms of non-cancelable operating leases. These leases expire at various times through December 2031. Minimum operating lease payments are $1.4 million in 2025, $1.4 million in 2026, $1.6 million in 2027, $1.7 million in 2028, $1.7 million in 2029, and $3.6 million thereafter.

Other Obligations and Contingencies

We from time-to-time are subject to claims and litigation in the normal course of business, none of which we believe represent a risk of material loss or exposure.

We have agreements with certain employees and an Executive Severance and Change in Control Plan which covers certain other employees which require payments if certain events, such as a change in control or termination without cause, occur.

Critical Accounting Estimates

We prepare our consolidated financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates and assumptions.

While we describe our significant accounting policies in Note 2 to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we have identified the following critical accounting estimates:

Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our incurred expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses are related to expenses incurred with respect to CROs, CMOs and other vendors in connection with research and development and manufacturing activities.

We base our expenses related to CROs and CMOs on our estimates of the services received and efforts expended pursuant to quotations and contracts with such vendors that conduct research and development and manufacturing activities on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the applicable research and development or manufacturing expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. There have been no material changes in estimates for the periods presented within this Annual Report on Form 10-K.

94

Table of Contents

Long-term Debt

We recognized a liability related to amounts received in January 2023, July 2023, January 2024, and September 2024 pursuant to the HCR Agreement under ASC 470-10, Debt and ASC 835-30, Interest – Imputation of Interest. The liability will be accreted under the effective interest method based upon the amount of contractual future payments to be made pursuant to the HCR Agreement. Amendments are assessed under ASC 470 to determine the appropriate treatment as troubled debt restructurings, extinguishments or modifications. If the timing or amounts of any future payments change, we will prospectively adjust the effective interest and the related amortization of the liability. See Note 13 to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K for additional information.

Prelaunch Inventory

We capitalize prelaunch inventory prior to receiving regulatory approval if regulatory approval and subsequent commercialization of a product is probable and we also expect future economic benefit from the sales of the product to be realized. Prior to this conclusion, we expense prelaunch inventory as research and development expense in the period incurred. For prelaunch inventory that is capitalized, we consider a number of specific facts and circumstances, including the product’s historical shelf life, the product's current status in the development and regulatory approval process, results from related clinical trials, results from meetings with relevant regulatory agencies prior to the filing of regulatory applications, potential obstacles to the approval process, viability of commercialization and market trends. In late 2023, based on our assessment of the legal and regulatory process related to YUTREPIA, we concluded that we met the criteria to capitalize expenditures for prelaunch inventory. We capitalized $10.8 million of prelaunch inventory as of December 31, 2024 and none as of December 31, 2023. We do not have an allowance for inventory obsolescence as of December 31, 2024. If either regulatory approval or market acceptance post-approval of YUTREPIA do not occur at all or on a timely basis prior to the inventory shelf-life expiration, we may be required to write-off some or all prelaunch inventory, which could affect our financial condition and financial results.

Smaller Reporting Company

As a “smaller reporting company,” as defined under Rule 12b-2 of the Exchange Act, in addition to providing reduced disclosure about our executive compensation arrangements and business developments, among other reduced disclosure requirements available to smaller reporting companies, we present only two years of audited financial statements in addition to any required unaudited interim financial statements with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure.

We will be able to take advantage of these scaled disclosures for so long as (i) our common stock held by non-affiliates is less than $250 million measured on the last business day of our second fiscal quarter, or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and our common stock held by non-affiliates is less than $700 million measured on the last business day of our second fiscal quarter. To the extent we take advantage of any reduced disclosure obligations, it may make it harder for investors to analyze the Company’s results of operations and financial prospectus in comparison with other public companies. Until we cease to be a smaller reporting company, the scaled-back disclosure in our SEC filings will result in less information about our company being available than for other public companies.

Off-Balance Sheet Arrangements

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

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing in this Annual Report on Form 10-K. This discussion and other parts of this Annual Report on Form 10-K contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, 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.

Objective

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide information necessary to understand our audited consolidated financial statements for the two-year period ended December 31, 2023 and highlight certain other information which, in the opinion of management, will enhance a reader’s understanding of our financial condition, changes in financial condition, results of operations, and cash flows. In particular, the discussion is intended to provide an analysis of significant trends and material changes in our financial position and the operating results of our business during the year ended December 31, 2023, as compared to the year ended December 31, 2022. This discussion should be read in conjunction with our consolidated financial statements for the two-year period ended the year ended December 31, 2023 and related notes included elsewhere in this Annual Report on Form 10-K.

Overview

We are a biopharmaceutical company focused on the development, manufacture, and commercialization of products that address unmet patient needs, with current focus directed towards rare cardiopulmonary diseases such as pulmonary arterial hypertension (“PAH”) and pulmonary hypertension associated with interstitial lung disease (“PH-ILD”). We operate through our wholly owned operating subsidiaries, Liquidia Technologies, Inc. (“Liquidia Technologies”) and Liquidia PAH, LLC (“Liquidia PAH”), formerly known as RareGen, LLC (“RareGen”).

We currently generate revenue pursuant to a promotion agreement between Liquidia PAH and Sandoz Inc. (“Sandoz”), dated as of August 1, 2018, as amended (the “Promotion Agreement”), sharing profit derived from the sale of Sandoz’s substitutable generic treprostinil injection (“Treprostinil Injection”) in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. We employ a targeted sales force calling on physicians and hospital pharmacies involved in the treatment of PAH and PH-ILD in the United States, as well as key stakeholders involved in the distribution and reimbursement of medicines to treat these patients. We established our commercial presence in the field to support Treprostinil Injection, and have since expanded our presence to support the launch of YUTREPIA upon final approval, further validating our reputation as a company committed to supporting PAH and PH-ILD patients.

We conduct research, development and manufacturing of novel products by applying our subject matter expertise in cardiopulmonary diseases and our proprietary PRINT® technology, a particle engineering platform, to enable precise production of uniform drug particles designed to improve the safety, efficacy and performance of a wide range of therapies. Through development of our own products and research with third parties, we have experience applying PRINT across multiple routes of administration and drug payloads including inhaled therapies, vaccines, biologics, nucleic acids and ophthalmic implants, among others.

Our lead product candidate is YUTREPIA for the treatment of PAH and PH-ILD. YUTREPIA is an inhaled dry powder formulation of treprostinil designed with PRINT to improve the therapeutic profile of treprostinil by enhancing deep lung delivery while using a convenient, low effort dry-powder inhaler (“DPI”) and by achieving higher dose levels than the labeled doses of current inhaled therapies. In November 2021, the United States Food and Drug Administration (“FDA”) tentatively approved our New Drug Application (“NDA”) for YUTREPIA for the treatment of PAH. In July 2023, we filed an amendment to our NDA to add PH-ILD to the label for YUTREPIA. Final FDA approval of

Table of Contents

YUTREPIA can occur for both PAH and PH-ILD after the new clinical investigation exclusivity granted to Tyvaso in PH-ILD expires on March 31, 2024.

We are also developing L606, an investigational, liposomal formulation of treprostinil administered twice-daily with a short-duration next-generation nebulizer, which we licensed from Pharmosa Biopharm. L606 is currently being evaluated in an open-label study in the United States for treatment of PAH and PH-ILD with a planned pivotal study for the treatment of PH-ILD.

Since our inception, we have incurred significant operating losses. Our net loss was $78.5 million and $41.0 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, we had an accumulated deficit of $429.1 million. We expect to incur significant expenses and operating losses for the foreseeable future as we conduct clinical development of product candidates and seek regulatory approval and prepare for commercialization of any approved product candidates. These efforts require significant amounts of capital, adequate personnel and infrastructure, and extensive compliance-reporting capabilities. Even if our development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales. Additionally, the Revenue Interest Financing Agreement with HealthCare Royalty Partners IV, L.P. (“HCR”) dated January 9, 2023, as amended (the “RIFA”) contains fixed quarterly payments and minimum cash covenants that require us to maintain cash and cash equivalents in an amount at least equal to $7.5 million during the calendar year beginning on January 1, 2024 and at least equal to $15.0 million for the remainder of the payment term after the calendar year ended December 31, 2024.

Our future funding requirements will be heavily determined by the timing of the potential commercialization of YUTREPIA and the resources needed to support the development of our product candidates. We may require additional capital to fund operations as well as to pursue in-licenses or acquisitions of other product candidates. If we determine we require but are unable to obtain additional funding, we could be required to delay, reduce, or eliminate research and development programs, product portfolio expansion, or future commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations.

Although we expect to continue to generate operating losses for the foreseeable future, we believe that based on our current operating plan, excluding any future YUTREPIA product revenue, our cash and cash equivalents will be sufficient to fund operations, capital expenditures, and RIFA quarterly fixed payment requirements and allow us to remain in compliance with our minimum cash covenants pursuant to the RIFA for at least twelve months from the issuance date of these consolidated financial statements. If we have not received full FDA approval and begun product sales of YUTREPIA or are unable to access additional capital by the date of issuance of our second quarter 2024 financial statements, there could be substantial doubt about our ability to continue as a going concern as of that date. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

Recent Events

Fourth Amendment to Revenue Interest Financing Agreement

On January 3, 2024, we entered into the Fourth Amendment to the RIFA pursuant to which HCR moved $25.0 million from the third tranche to the second tranche, such that HCR will have funded a total of $35.0 million under the second tranche. The additional $25.0 million from the second tranche was funded on January 4, 2024. The remaining third tranche of $10.0 million and fourth tranche of $22.5 million can be funded in the future upon the mutual agreement of both parties. See Note 12 for further information.

Private Placement

On January 4, 2024, we entered into a Common Stock Purchase Agreement with Legend Aggregator, LP, for the sale by us in a private placement (the “2024 Private Placement”) of an aggregate of 7,182,532 shares of our common stock at a purchase price of $10.442 per share. The 2024 Private Placement closed on January 8, 2024, and we received gross proceeds of approximately $75.0 million, before deducting offering costs of less than $0.1 million.

Components of Statements of Operations

Revenue

We primarily generate revenue pursuant to the Promotion Agreement, under which we receive a 50% share in the profit derived from the sale of Treprostinil Injection in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. In May 2021, Liquidia PAH’s manufacturing partner, Chengdu Shifeng Medical Technologies LTD (“Chengdu”) began selling the RG Cartridge, which may be used to supply medications to PAH patients with the CADD-MS 3 pump manufactured by Smiths Medical ASD, Inc. We are aware of shortages of critical components of the CADD-MS 3 pump that have caused the number of CADD-MS 3 infusion pumps available for the subcutaneous administration of Treprostinil Injection to be limited. Due to this limitation in the availability of pumps, specialty pharmacies are not currently placing new patients on to subcutaneous Treprostinil Injection therapy in order to preserve the available pumps for those patients already receiving subcutaneous administration of Treprostinil Injection. In December 2022, we entered into a Device Development and Supply Agreement (the “Pump Development Agreement”) with Mainbridge Health Partners, LLC (“Mainbridge”) and Sandoz. The Pump Development Agreement provides for the cooperation between us, Sandoz and Mainbridge to develop a new pump that is suitable for the subcutaneous administration of Treprostinil Injection. Mainbridge will perform all development, validation and testing activities required for the pump and related consumables in anticipation of submitting a 510(k) clearance application for the pump to the FDA in the first half of 2024. Future revenue will continue to be impacted until new components or alternative pumps are available.

Cost of Revenue

Cost of revenue consists of (i) an allocation of the cost of our sales force associated with calling on physicians and hospital pharmacies involved in the treatment of PAH with Treprostinil Injection, as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection and (ii) amortization of the intangible asset associated with the Promotion Agreement. We amortize the intangible asset associated with the Promotion Agreement in a manner consistent with our recognition of the related revenue.

Research and Development Expenses

Research and development expenses consist of expenses incurred in connection with the development of our product candidates. We expense research and development costs as incurred. These expenses include:

79

Table of Contents

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. In the near term we expect that our research and development expenses to increase as we complete manufacturing activities, conduct existing clinical trials, and initiate potential clinical trials. However, levels of research and development spending are highly dependent upon the selection and progression of product candidates. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if ever, material net cash inflows may commence from any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals. We may never succeed in achieving regulatory approval for any of our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, or our ability to manufacture and supply product, we could be required to expend significant additional financial resources and time on the completion of clinical development. Drug commercialization can take several years and millions of dollars in development costs.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance and legal functions, including stock-based compensation. Other general and administrative expenses include facility-related costs, patent filing and prosecution costs and professional fees for marketing, legal, auditing and tax services and insurance costs.

Other Income (Expense)

Other income (expense) is comprised of interest income and expense and loss on extinguishment of debt. Interest income consists of interest earned on our cash equivalents. Interest expense consists of interest charges on the revenue interest financing payable, finance leases and long-term debt. These charges include monthly recurring interest on such obligations in addition to interest accretion and amortization of debt discounts and issuance costs to interest expense.

Comparison of the Years Ended December 31, 2023 and 2022

The following table summarizes our results of operations:

​

​

Revenue

Revenue was $17.5 million for the year ended December 31, 2023, compared with $15.9 million for the year ended December 31, 2022. Revenue related primarily to the Promotion Agreement. The increase of $1.6 million was primarily due to favorable gross-to-net chargeback, rebate, and managed care adjustments offset by the impact of lower sales quantities as compared to the prior year.

Cost of Revenue

Cost of revenue was $2.9 million for the year ended December 31, 2023, compared with $2.9 million for the year ended December 31, 2022. Cost of revenue related to the Promotion Agreement as noted above. During the fourth quarter of 2024, our sales force expanded in size, however, this increase was offset by a decrease in amortization.

Research and Development Expenses

Research and development expenses were $43.2 million for the year ended December 31, 2023 compared with $19.4 million for the year ended December 31, 2022. The increase of $23.8 million or 122% was driven largely by the $10.0 million upfront license fee payment to Pharmosa for the exclusive license in North America to develop and commercialize L606. We incurred an additional $2.6 million in expenses related to our L606 program during the year ended December 31, 2023. Expenses related to our YUTREPIA program increased by $6.3 million from $6.7 million during the year ended December 31, 2022 to $13.0 million during the year ended December 31, 2023 primarily due to increased manufacturing activities related to pre-launch commercial supply and the startup of our ASCENT study during 2023. Personnel and consulting expenses, including stock compensation expense, increased $5.1 million primarily due to increased headcount to support the potential commercialization of YUTREPIA.

General and Administrative Expenses

General and administrative expenses were $44.7 million for the year ended December 31, 2023, compared with $32.4 million for the year ended December 31, 2022. The increase of $12.3 million or 38% was primarily due to a $9.8 million increase in personnel and consulting expenses, including stock-based compensation, and a $1.4 million increase in commercial expenses in preparation for the potential commercialization of YUTREPIA.

Table of Contents

Other Income (Expense)

Total other expense, net was $5.1 million for the year ended December 31, 2023, compared with $2.2 million for the year ended December 31, 2022. The increase of $2.9 million was primarily due to a $3.9 million increase in interest expense attributable to the higher borrowings under the RIFA as compared to balances outstanding under the A&R SVB LSA and a $1.3 million increase in loss on extinguishment of debt due offset by a $2.4 million increase in interest income attributable to higher money market yields. The year ended December 31, 2023 included a $2.3 million loss on extinguishment of debt related to repayment of the A&R SVB LSA in January 2023. The year ended December 31, 2022 included a $1.0 million loss on extinguishment of debt related to the refinance of our long-term debt with SVB in January 2022.

Liquidity and Capital Resources

Sources of Liquidity

We have financed our growth and operations through a combination of funds generated from revenues, the issuance of convertible preferred stock and common stock, bank borrowings, the issuance of convertible notes, and revenue interest financing. Our principal uses of cash have been for working capital requirements and capital expenditures. As of December 31, 2023, we had cash and cash equivalents of $83.7 million, stockholders’ equity of $47.3 million, and an accumulated deficit of $429.1 million.

In January 2024, we sold 7,182,532 shares of our common stock in a private placement (the “2024 Private Placement”) at a purchase price of $10.442 per share for gross proceeds of approximately $75.0 million, before deducting offering expenses of less than $0.1 million.

In December 2023, we sold 3,491,620 shares of our common stock in an underwritten registered public offering at an offering price of $7.16 per share for gross proceeds of approximately $25.0 million, before deducting offering costs of approximately $1.9 million.

In December 2023, we also entered into a common stock purchase agreement with Roger Jeffs, our Chief Executive Officer, for the sale by us in a private placement of an aggregate of 139,665 shares of our common stock at a purchase price of $7.16 per share for gross proceeds of approximately $1.0 million.

In January 2023, we entered into a Revenue Interest Financing Agreement with HealthCare Royalty Partners IV, L.P. (“HCR”), as amended (the “RIFA”), pursuant to which HCR has agreed to pay us an aggregate investment amount of up to $100.0 million (the “Investment Amount”). $32.5 million of the Investment Amount was funded on January 27, 2023 (the “Initial Investment Amount”), $22.2 million of which was used to satisfy in full and retire the Company’s indebtedness with Silicon Valley Bank with the excess proceeds funded to the Company. An additional $10.0 million of the Investment Amount was funded on July 27, 2023 (the “Second Tranche Amount”), which was used to fund payment of the $10.0 million upfront license fee due under the Pharmosa License Agreement. $25.0 million of the Investment Amount was funded on January 4, 2024. See “Recent Events” above for further information.

In April 2022, we sold 11,274,510 shares of our common stock in an underwritten registered public offering at an offering price of $5.10 per share for net proceeds of approximately $54.5 million from the sale of the shares, after deducting the underwriting discounts and commissions and other offering expenses.

Future Funding Requirements

Prior to the potential FDA approval of YUTREPIA and until such time as we can generate significant revenues from its sale, if ever, we anticipate we will incur net losses and negative cash flows. We plan to focus in the near-term on preparations for the potential commercial launch of YUTREPIA, continuing promotion of Treprostinil Injection, investing in research and development efforts for our YUTREPIA and L606 programs, and expanding our corporate infrastructure. We may not be able to complete the development and initiate commercialization of these programs if,

82

Table of Contents

among other things, our clinical trials are not successful or if the FDA does not approve our product candidates when we expect, or at all.

Our primary uses of capital are, and we expect will continue to be, compensation and related personnel expenses, clinical costs, manufacturing process development costs, external research and development services, laboratory and related supplies, regulatory expenses, legal costs, administrative and overhead costs and repayments under the RIFA. We also expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution as we prepare to potentially receive regulatory approval for YUTREPIA. Our future funding requirements will be heavily determined by the timing of the potential commercialization of YUTREPIA and the resources needed to support the development of our product candidates.

We may raise additional capital through licensing activities, other business arrangements or the sale of equity or convertible debt securities. In such an event, the ownership of our existing shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights associated with holdings of our common stock.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceuticals, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Cash Flows

The following table summarizes our sources and uses of cash:

​

​

Table of Contents

Operating Activities

Net cash used in operating activities increased $13.0 million to $41.6 million for the year ended December 31, 2023, from $28.6 million for the year ended December 31, 2022. The increase was primarily due to $21.0 million higher net loss adjusted for non-cash items offset by unfavorable working capital changes of $8.0 million.

Investing Activities

Net cash used in investing activities was $11.3 million for the year ended December 31, 2023 compared to $0.6 million for the year ended December 31, 2022. During the year ended December 31, 2023, we made a $10.0 million upfront license fee payment to Pharmosa for the exclusive license in North America to develop and commercialize L606 and paid $1.3 million for the acquisition of property, plant and equipment. During the year ended December 31, 2022, net cash used in investing activities related to property, plant and equipment purchases.

Financing activities

Net cash provided by financing activities was $43.2 million during the year ended December 31, 2023 compared with $65.0 million provided by financing activities the year ended December 31, 2022. During the year ended December 31, 2023, we received $41.7 million net proceeds from the revenue interest financing agreement of which $22.2 million was used to repay existing indebtedness with Silicon Valley Bank, $24.2 million aggregate net proceeds from the sale of common stock in a public offering and a public private placement, and $1.2 million from the issuance of common stock under stock incentive plans. These inflows were offset by $1.7 million in payments under the RIFA and $0.1 million in principal payments on our finance leases. During the year ended December 31, 2022, we received $54.5 million net proceeds from the sale of common stock, $9.3 million excess proceeds from the refinancing of long-term debt, and $1.1 million from the issuance of common stock under stock incentive plans.

Contractual Obligations and Commitments

Milestone and Royalty Obligations

Under the UNC License Agreement, the Company is obligated to pay UNC royalties equal to a low single digit percentage of all net sales of drug products whose manufacture, use or sale includes any use of the technology or patent rights covered by the UNC License Agreement, including YUTREPIA.

In March 2012, we entered into an agreement, as amended, with Chasm Technologies, Inc. for manufacturing consulting services related to our manufacturing capabilities during the term of the agreement. We agreed to pay future contingent milestones and royalties, totaling no more than $1.5 million, $0.2 million of which was accrued as of December 31, 2023.

In December 2022, we entered into a Device Development and Supply Agreement (the “Pump Development Agreement”) with Mainbridge Health Partners, LLC (“Mainbridge”) and Sandoz Inc. (“Sandoz”). The Pump Development Agreement provides for the cooperation between us, Sandoz and Mainbridge to develop a new pump that is suitable for the subcutaneous administration of Treprostinil Injection. Mainbridge will perform all development, validation and testing activities required for the pump and related consumables in anticipation of submitting a 510(k) clearance application for the pump to the FDA in the first half of 2024. In connection with the Pump Development Agreement, we and Sandoz have agreed to pay Mainbridge certain future contingent milestone payments in accordance with the terms and conditions set forth therein.

In June 2023, we entered into a License Agreement with Pharmosa Biopharm Inc. (“Pharmosa”) pursuant to which we were granted an exclusive license in North America to develop and commercialize L606, an inhaled, sustained-release formulation of treprostinil currently being evaluated in a clinical trial for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD), and a non-exclusive license for the manufacture, development and use (but not commercialization) of such licensed product in most countries outside North America. In consideration for these exclusive rights, we will pay Pharmosa potential development

84

Table of Contents

milestone payments tied to PAH and PH-ILD indications of up to $30 million, potential sales milestones of up to $185 million and two tiers of low, double-digit royalties on net sales of L606. Pharmosa will also receive a $10 million milestone payment for each additional indication approved after PAH and PH-ILD and each additional product approved under the license.

Purchase Obligations

We enter into contracts in the normal course of business with contract service providers to assist in the performance of our research and development and manufacturing activities. Subject to required notice periods and our obligations under binding purchase orders, we can elect to discontinue the work under these agreements at any time.

On July 14, 2023, the Company entered into an Amended and Restated Commercial Manufacturing Services and Supply Agreement with Lonza Tampa LLC. Pursuant to the terms of the Agreement, Lonza provides us with manufacturing and storage services for YUTREPIA inhalation powder. We will deliver bulk treprostinil powder, manufactured using our proprietary PRINT® technology, and Lonza will encapsulate and package the Product. Under the terms of the Agreement, we have agreed that upon any Termination for FDA Rejection or Termination for FDA Delay, we would reimburse Lonza for 50% of its documented out-of-pocket expenditures for any capital equipment that is purchased by Lonza after the effective date of the Agreement to perform the services for us, not to exceed $2.5 million in the aggregate. As of December 31, 2023, we had non-cancelable commitments with Lonza Tampa LLC for product manufacturing costs of approximately $4.1 million for the year ending December 31, 2024.

In addition, we have entered into a multi-year supply agreement with LGM Pharma, LLC (“LGM”) to produce active pharmaceutical ingredients for YUTREPIA. Under our supply agreement with LGM, we are required to provide rolling forecasts, a portion of which will be considered a binding, firm order, subject to an annual minimum purchase commitment of $2.7 million for the term of the agreement. As of December 31, 2023, we have incurred and paid the full annual purchase commitment for 2023 of $2.7 million. The agreement expires five years from the first marketing authorization approval of YUTREPIA.

Concurrently with the execution of the Pharmosa License Agreement, we also entered into an Asset Transfer Agreement with Pharmosa pursuant to which Pharmosa will transfer its inventory of physical materials.

Lease Obligations

We have operating lease obligations including rental amounts due on leases of certain laboratory, manufacturing and office space and equipment under the terms of non-cancelable operating leases. These leases expire at various times through October 2026. Minimum operating lease payments are $1.3 million in 2024, $1.4 million in 2025, and $1.2 million in 2026.

Other Obligations and Contingencies

We from time-to-time are subject to claims and litigation in the normal course of business, none of which we believe represent a risk of material loss or exposure.

We also have employment agreements with certain employees which require the funding of a specific level of payments, if certain events, such as a change in control or termination without cause, occur.

Critical Accounting Estimates

We prepare our consolidated financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates and assumptions.

85

Table of Contents

While we describe our significant accounting policies in Note 2 to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we have identified the following critical accounting estimates:

Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our incurred expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses are related to expenses incurred with respect to CROs, CMOs and other vendors in connection with research and development and manufacturing activities.

We base our expenses related to CROs and CMOs on our estimates of the services received and efforts expended pursuant to quotations and contracts with such vendors that conduct research and development and manufacturing activities on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the applicable research and development or manufacturing expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. There have been no material changes in estimates for the periods presented within this Annual Report on Form 10-K.

Revenue Interest Financing Agreement

We recognized a liability related to amounts received in January 2023 and July 2023 pursuant to the RIFA with HCR under ASC 470-10, Debt and ASC 835-30 Interest - Imputation of Interest. The liability will be accreted under the effective interest method based upon the estimated amount of future payments to be made pursuant to the RIFA. The issuance costs were recorded as a deduction to the carrying amount of the liability and will be amortized under the effective interest method over the estimated period in which the liability will be repaid. If the timing or amounts of any estimated future payments change, we will prospectively adjust the effective interest and the related amortization of the liability and related issuance costs. A significant increase or decrease in these estimates could materially impact the liability balance and related interest expense. There were no significant changes to the effective interest rate since initial recognition of the liability.

Objective

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide information necessary to understand our audited consolidated financial statements for the two-year period ended December 31, 2022 and highlight certain other information which, in the opinion of management, will enhance a reader’s understanding of our financial condition, changes in financial condition, results of operations, and cash flows. In particular, the discussion is intended to provide an analysis of significant trends and material changes in our financial position and the operating results of our business during the year ended December 31, 2022, as compared to the year ended December 31, 2021. This discussion should be read in conjunction with our consolidated financial statements for the two-year period ended the year ended December 31, 2022 and related notes included elsewhere in this Annual Report on Form 10-K.

Overview

We are a biopharmaceutical company focused on the development, manufacture, and commercialization of products that address unmet patient needs, with current focus directed towards the treatment of pulmonary hypertension (PH). We operate as a single entity through our two wholly owned operating subsidiaries, Liquidia Technologies and Liquidia PAH.

We currently generate revenue pursuant to a Promotion Agreement between Liquidia PAH and Sandoz Inc. (“Sandoz”) sharing profit derived from the sale of the first-to-file fully substitutable generic treprostinil injection (“Treprostinil Injection”) in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. We employ a targeted sales force calling on physicians and hospital pharmacies in the treatment of pulmonary arterial hypertension (PAH), as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection. Strategically, we believe that our commercial presence in the field will enable an efficient base to expand from for the launch of YUTREPIA upon approval, leveraging existing relationships and further validating our reputation as a company committed to supporting PAH patients.

We conduct research, development, and manufacturing of novel products by applying our subject matter expertise in cardiopulmonary diseases and our proprietary PRINT® technology, a particle engineering platform which enables precise production of uniform drug particles designed to improve the safety, efficacy, and performance of a wide range of therapies. Through development of our own products and research with third parties, we have developed expertise in applying PRINT across multiple routes of administration and drug payloads including inhaled therapies, vaccines, biologics, nucleic acids and ophthalmic implants, among others.

Our lead product candidate is YUTREPIA for the treatment of PAH. YUTREPIA is an inhaled dry powder formulation of treprostinil designed with PRINT to improve the therapeutic profile of treprostinil by enhancing deep lung delivery while using a convenient, low resistance dry-powder inhaler (“DPI”) and by achieving higher dose levels than current inhaled therapies. The United States Food and Drug Administration (FDA) tentatively approved our New Drug Application (NDA) for YUTREPIA for the treatment of PAH in November 2021. The FDA also confirmed that the clinical data in the NDA would support our pursuit of a supplemental NDA to treat patients with pulmonary hypertension and interstitial lung disease (PH-ILD) upon the expiration of regulatory exclusivity for the nebulized form of treprostinil in March 2024.

Since our inception, we have incurred significant operating losses. Our net loss was $41.0 million and $34.5 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $350.6 million. We expect to incur significant expenses and operating losses for the foreseeable future as we advance product candidates through clinical trials, seek regulatory approval and prepare for commercialization of any approved product candidates. In addition, we may incur expenses in connection with the in-license or acquisition of additional product candidates.

Recent Events

Revenue Interest Financing Agreement

On January 9, 2023, we entered into a Revenue Interest Financing Agreement (the “RIFA”) with HealthCare Royalty Partners IV, L.P. (“HCR”) and HealthCare Royalty Management, LLC. Pursuant to the RIFA and subject to customary closing conditions, HCR has agreed to pay us an aggregate investment amount of up to $100.0 million (the “Investment Amount”). Under the terms of the RIFA, $32.5 million of the Investment Amount was funded on January 27, 2023 (the “Initial Investment Amount”), $22.4 million of which was used to satisfy in full and retire our indebtedness under the Amended and Restated Loan and Security Agreement with Silicon Valley Bank (“SVB”) and SVB Innovation Credit Fund VIII, L.P. (“Innovation”) (the “A&R SVB LSA”), with the excess proceeds funded to the Company. See Note 16 to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K for information regarding repayment.

Device Development and Supply Agreement with Mainbridge and Sandoz

On December 1, 2022, we entered into a Device Development and Supply Agreement (the “Pump Development Agreement”) with Mainbridge Health Partners, LLC (“Mainbridge”) and Sandoz Inc. (“Sandoz”).

The Pump Development Agreement provides for the cooperation between us, Sandoz and Mainbridge to develop a new pump that is suitable for the subcutaneous administration of Treprostinil Injection. Mainbridge will perform all development, validation and testing activities required for the pump and related consumables in anticipation of submitting a 510(k) clearance application for the pump to the FDA in 2023. In connection with the Pump Development Agreement, we and Sandoz have agreed to pay Mainbridge certain future contingent milestone payments in accordance with the terms and conditions set forth therein.

​

Fourth Amendment to the Sandoz Promotion Agreement

On March 10, 2023, we entered into a Fourth Amendment to the Sandoz Promotion Agreement, which provides for, among other things, (i) an agreement between us and Sandoz to enter into an agreement with a third party for the repair and servicing of CADD-MS 3 pumps (the “New Agreement”), (ii) an agreement to split all payments due under the New Agreement evenly between us and Sandoz, and (iii) to clarify certain terms and conditions related to the profit sharing between us and Sandoz under the Promotion Agreement.

Components of Statements of Operations

Revenue

We primarily generate revenue pursuant to the Promotion Agreement, under which we receive a 50% share in the profit derived from the sale of Treprostinil Injection in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. On May 21, 2021, Liquidia PAH’s manufacturing partner, Chengdu Shifeng Medical Technologies LTD (“Chengdu”) began selling the RG Cartridge, which may be used to supply medications to PAH patients with the CADD-MS 3 pump manufactured by Smiths Medical ASD, Inc. We recently became aware of shortages of critical components of the CADD-MS 3 pump that have caused the number of CADD-MS 3 infusion pumps available for the subcutaneous administration of Treprostinil Injection to be limited.  Due to this limitation in the availability of pumps, specialty pharmacies are not currently placing new patients on to subcutaneous Treprostinil Injection therapy in order to preserve the available pumps for those patients already receiving subcutaneous administration of Treprostinil Injection.  As a result of these shortages, future revenue may be impacted until new components or alternative pumps are available. See Recent Events for more information.

Cost of Revenue

Cost of revenue consists of (i) the cost of employing a targeted sales force calling on physicians and hospital pharmacies involved in the treatment of PAH, as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection and (ii) a portion of the amortization of the intangible asset associated with the Promotion

70

Table of Contents

Agreement. We amortize the intangible asset associated with the Promotion Agreement in a manner consistent with our recognition of the related revenue.

Research and Development Expenses

Research and development expenses consist of expenses incurred in connection with the development of our product candidates. We expense research and development costs as incurred. These expenses include:

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. In the near term we expect that our research and development expenses to increase as we complete manufacturing activities and explore potential clinical trials. However, levels of research and development spending are highly dependent upon the selection and progression of product candidates. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if ever, material net cash inflows may commence from any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals, and the expense of filing, prosecuting, defending and enforcing any patent claims or other intellectual property rights. We may never succeed in achieving regulatory approval for any of our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. A change in the outcome of any of these variables with respect to the development of a product candidate

71

Table of Contents

could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, or our ability to manufacture and supply product, we could be required to expend significant additional financial resources and time on the completion of clinical development. Drug commercialization will take several years and millions of dollars in development costs.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance and legal functions, including stock-based compensation. Other general and administrative expenses include facility-related costs, patent filing and prosecution costs and professional fees for marketing, legal, auditing and tax services and insurance costs.

Other Income (Expense)

Other income (expense) is comprised of interest income and expense and loss on extinguishment of debt. Interest income consists of interest earned on our cash deposits. Interest expense consists of interest charges on finance leases and debt. These charges include monthly recurring interest on such obligations in addition to non-cash charges. Non-cash charges include interest accretion, expensing of debt issuance costs and amortization of discounts on long-term debt to interest expense.

Comparison of the Years Ended December 31, 2022 and 2021

The following table summarizes our results of operations:

​

​

Revenue

Revenue was $15.9 million for the year ended December 31, 2022, compared with $12.9 million for the year ended December 31, 2021. During the year ended December 31, 2022, the profit split percentage we received under the Promotion Agreement was 50%, whereas during the year ended December 31, 2021 the profit split percentage decreased from 80% to 50% as a result of achievement of predetermined cumulative sales thresholds. This decrease in profit split percentage was offset by an increase in the number of units sold.

72

Table of Contents

Cost of Revenue

Cost of revenue was $2.9 million for the year ended December 31, 2022, compared with $3.0 million for the year ended December 31, 2021. Cost of revenue related to the Promotion Agreement as noted above.

Research and Development Expenses

Research and development expenses were $19.4 million for the year ended December 31, 2022 compared with $20.5 million for the year ended December 31, 2021. The decrease of $1.1 million or 5% was primarily due to a $0.9 million decrease in personnel, consulting, and stock-based compensation expenses. During the year ended December 31, 2022 ended, we incurred $7.0 million related to YUTREPIA compared to $6.7 million during the year ended December 31, 2021.

General and Administrative Expenses

General and administrative expenses were $32.4 million for the year ended December 31, 2022, compared with $23.1 million for the year ended December 31, 2021. The increase of $9.3 million or 40% was primarily due to a $4.2 million increase in commercial, marketing, and personnel expenses in preparation for the potential commercialization of YUTREPIA and a $3.1 million increase in stock-based compensation expense driven by an option modification charge recorded in March 2022.

Other Income (Expense)

Total other expense, net was $2.2 million for the year ended December 31, 2022, compared with $0.8 million for the year ended December 31, 2021. The increase of $1.4 million was primarily due to a $1.0 million loss on extinguishment of debt related to the refinance of our long-term debt during January 2022 and a $1.6 million increase in interest expense due to a higher debt balance and higher interest rate on our debt from the A&R SVB LSA, offset by a $1.1 million increase in interest income from higher cash and cash equivalents balances.

Liquidity and Capital Resources

Sources of Liquidity

We have financed our growth and operations through a combination of funds generated from revenues, the issuance of convertible preferred stock and common stock, bank borrowings, the issuance of convertible notes, and revenue interest financing. Our principal uses of cash have been for working capital requirements and capital expenditures. As of December 31, 2022, we had cash and cash equivalents of $93.3 million, stockholders’ equity of $90.4 million and an accumulated deficit of $350.6 million.

In January 2023, we entered into a Revenue Interest Financing Agreement (the “RIFA”) with HealthCare Royalty Partners IV, L.P. (“HCR”) and HealthCare Royalty Management, LLC. Pursuant to the RIFA and subject to customary closing conditions, HCR has agreed to pay the Company an aggregate investment amount of up to $100.0 million (the “Investment Amount”). Under the terms of the RIFA, $32.5 million of the Investment Amount was funded on January 27, 2023 (the “Initial Investment Amount”), $22.4 million of which was used to satisfy in full and retire the Company’s indebtedness under the A&R SVB LSA. See “Recent Events” above for further information.

In April 2022, we sold 11,274,510 shares of our common stock in an underwritten registered public offering at an offering price of $5.10 per share (the “Offering”). The Offering closed on April 18, 2022, and we received net proceeds of approximately $54.5 million from the sale of the shares, after deducting the underwriting discounts and commissions and other offering expenses. We intend to use the net proceeds from this Offering for ongoing commercial development of YUTREPIA, for continued development of YUTREPIA in other clinical trials, for pre-clinical pipeline activities and for general corporate purposes.

73

Table of Contents

In January 2022, we entered into the A&R SVB LSA with SVB and Innovation, which provided us with up to $40.0 million in term loans of which $20.0 million was funded, $10.5 million of which was used to satisfy our existing obligations under the Loan and Security Agreement with SVB dated February 26, 2021 (“the “SVB LSA”), with the excess proceeds of approximately $9.5 million funded to the Company. The debt facility was to mature on December 1, 2025 and consisted of interest-only payments through December 31, 2023. The outstanding principal amount of the term loans accrued interest at a floating rate per annum equal to the greater of 7.25% and the prime rate of interest plus 4.0%.

In April 2021, we entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with certain institutional, accredited investors (the “Purchasers”) for the sale by us in a private placement (the “Private Placement”) of an aggregate of 8,626,037 shares (the “Private Placement Shares”) of our common stock, at a purchase price of $2.52 per Private Placement Share. The gross proceeds from the sale of the Private Placement Shares were $21.7 million.

Future Funding Requirements

Prior to the potential FDA approval of YUTREPIA and until such time as we can generate significant revenues from its sale, if ever, we anticipate we will incur net losses and negative cash flows. We plan to focus in the near-term on preparations for the potential commercial launch of YUTREPIA, continuing promotion of Treprostinil Injection, expanding our corporate infrastructure, and continuing to invest in research and development efforts to explore additional product candidates. We may not be able to complete the development and initiate commercialization of these programs if, among other things, our clinical trials are not successful or if the FDA does not approve our product candidates when we expect, or at all.

Our primary uses of capital are, and we expect will continue to be, compensation and related personnel expenses, clinical costs, manufacturing process development costs, external research and development services, laboratory and related supplies, regulatory expenses, legal costs, administrative and overhead costs and repayments under the RIFA. We also expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution as we prepare to potentially receive regulatory approval for YUTREPIA. Our future funding requirements will be heavily determined by the timing of the potential commercialization of YUTREPIA and the resources needed to support development of our product candidates.  If the Company is unable to access the contingent Investment Amounts from the RIFA or generate substantial YUTREPIA product revenue by the second quarter of 2024, the Company will require additional capital.

We believe based on our current operating plan, excluding any potential contingent Investment Amounts from the RIFA and future YUTREPIA product revenue, that cash and cash equivalents will be sufficient to fund operations and capital expenditure requirements and allow us to remain in compliance with our minimum cash covenants pursuant to the RIFA for at least twelve months from the issuance date of this Annual Report on Form 10-K. If we are unable to access additional Investment Amounts from the RIFA, there could be substantial doubt about our ability to continue as a going concern as of the date of the issuance of our second quarter 2023 financial statements. We have based these estimates on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. We may also require additional capital to pursue in-licenses or acquisitions of other product candidates. If we conclude that we require but are unable to obtain additional funding, we could be required to delay, reduce, or eliminate research and development programs, product portfolio expansion, or future commercialization efforts, which could adversely affect business prospects.

We may raise additional capital through licensing activities, other business arrangements or the sale of equity or convertible debt securities. In such an event, the ownership of our existing shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights associated with holdings of our common stock.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceuticals, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

74

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Cash Flows

The following table summarizes our sources and uses of cash:

​

​

Operating Activities

Net cash used in operating activities decreased $5.4 million to $28.6 million for the year ended December 31, 2022, from $34.0 million for the year ended December 31, 2021. The decrease was primarily due to working capital changes of $10.2 million offset by $4.8 million higher net loss adjusted for non-cash items. The increase in working capital was primarily driven by the timing of receipts from Sandoz in connection with the Promotion Agreement and the timing of vendor payments.

Investing Activities

Net cash used in investing activities was $0.6 million for the year ended December 31, 2022 compared to $0.1 million for the year ended December 31, 2021 and consisted primarily of property, plant and equipment purchases.

Financing activities

Net cash provided by financing activities was $65.0 million during the year ended December 31, 2022 compared with $26.3 million provided by financing activities the year ended December 31, 2021. During the year ended December 31, 2022, we received $54.5 million net proceeds from the Offering which closed on April 18, 2022, $9.3 million excess proceeds from the refinancing of our long-term debt in January 2022, $1.1 million from the issuance of common stock under stock incentive plans, and $0.5 million in litigation financing deployments. These inflows were offset by $0.3 million in principal payments on our finance leases. During the year ended December 31, 2021, we received $21.7 million net proceeds from the Private Placement which closed on April 13, 2021, $5.0 million in litigation financing deployments, and $0.1 million excess proceeds from the refinancing of our long-term debt. These

75

Table of Contents

inflows were offset by $0.5 million in principal payments on our finance leases. Funds received from litigation deployments are paid directly to the attorneys involved in the RareGen Litigation (as described in Item 3, Legal Proceedings), ongoing costs of which are included as operating outflows.

Contractual Obligations and Commitments

Milestone and Royalty Obligations

Under the UNC License Agreement, the Company is obligated to pay UNC royalties equal to a low single digit percentage of all net sales of drug products whose manufacture, use or sale includes any use of the technology or patent rights covered by the UNC License Agreement, including YUTREPIA.

​

In March 2012, the Company entered into an agreement, as amended, with Chasm Technologies, Inc. for manufacturing consulting services related to the Company’s manufacturing capabilities during the term of the agreement. The Company agreed to pay future contingent milestones and royalties on net sales totaling no more than $1.5 million, none of which has been earned as of December 31, 2022.

Purchase Obligations

We enter into contracts in the normal course of business with contract service providers to assist in the performance of our research and development and manufacturing activities. Subject to required notice periods and our obligations under binding purchase orders, we can elect to discontinue the work under these agreements at any time. As of December 31, 2022, the Company has non-cancelable commitments for product manufacturing costs of approximately $3.7 million for the year ending December 31, 2023.

In addition, we have entered into a multi-year supply agreement with LGM Pharma, LLC (“LGM”) to produce active pharmaceutical ingredients for YUTREPIA. Under our supply agreement with LGM, we are required to provide rolling forecasts, a portion of which will be considered a binding, firm order, subject to an annual minimum purchase commitment of $2.7 million for the term of the agreement. The agreement expires five years from the first marketing authorization approval of YUTREPIA.

Lease Obligations

We have operating lease obligations including rental amounts due on leases of certain laboratory, manufacturing and office space and equipment under the terms of non-cancelable operating leases. These leases expire at various times through October 2026. Minimum operating lease payments are $1.3 million in 2023, $1.3 million in 2024, $1.4 million in 2025, and $1.2 million in 2026.

We lease specialized laboratory equipment under finance leases expiring in 2024. Minimum finance lease payments are $0.2 million in 2023, and $0.1 million in 2024.

Other Obligations and Contingencies

We from time-to-time are subject to claims and litigation in the normal course of business, none of which we believe represent a risk of material loss or exposure.

We also have employment agreements with certain employees which require the funding of a specific level of payments, if certain events, such as a change in control or termination without cause, occur.

Critical Accounting Estimates

We prepare our consolidated financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and

76

Table of Contents

liabilities at the date of the financial statements and reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates and assumptions.

While we describe our significant accounting policies in Note 2 to the consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we have identified the following critical accounting estimates:

Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our incurred expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses are related to expenses incurred with respect to CROs, CMOs and other vendors in connection with research and development and manufacturing activities. We do not currently capitalize costs associated with the production of YUTREPIA.

We base our expenses related to CROs and CMOs on our estimates of the services received and efforts expended pursuant to quotations and contracts with such vendors that conduct research and development and manufacturing activities on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the applicable research and development or manufacturing expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. There have been no material changes in estimates for the periods presented within this Annual Report on Form 10-K.

JOBS Act

As an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), we can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies.

Subject to certain conditions, as an emerging growth company, we rely on certain of these exemptions, including without limitation:

We may take advantage of these exemptions for up to five years or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company on the date that is the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (ii) the last day of 2023; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC. We may choose to take advantage of some but not all of these exemptions.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing in this Annual Report on Form 10-K. This discussion and other parts of this Annual Report on Form 10-K contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, 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.

Objective

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide information necessary to understand our audited consolidated financial statements for the two-year period ended December 31, 2021 and highlight certain other information which, in the opinion of management, will enhance a reader’s understanding of our financial condition, changes in financial condition and results of operations. In particular, the discussion is intended to provide an analysis of significant trends and material changes in our financial position and the operating results of our business during the year ended December 31, 2021, as compared to the year ended December 31, 2020. This discussion should be read in conjunction with our consolidated financial statements for the two-year period ended December 31, 2021 and related notes included elsewhere in this annual report on Form 10-K.

Overview

We are a biopharmaceutical company focused on the development, manufacturing and commercialization of products that address unmet patient needs, with current focus directed towards the treatment of pulmonary hypertension (PH). We operate as a single entity through our two wholly owned operating subsidiaries, Liquidia Technologies and Liquidia PAH (formerly known as RareGen).

We generate revenue pursuant to a Promotion Agreement between Liquidia PAH and Sandoz Inc. (“Sandoz”) sharing profit derived from the sale of the first-to-file fully substitutable generic treprostinil injection (“Treprostinil Injection”) in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. We employ a targeted sales force calling on physicians and hospital pharmacies in the treatment of pulmonary arterial hypertension (“PAH”), as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection. Strategically, we believe that our commercial presence in the field will enable an efficient base to expand from for the launch of YUTREPIA upon approval, leveraging existing relationships and further validating our reputation as a company committed to supporting PAH patients.

We conduct research, development and manufacturing of novel products by applying our proprietary PRINT® technology, a particle engineering platform, to enable precise production of uniform drug particles designed to improve the safety, efficacy and performance of a wide range of therapies. We have development experience in inhaled therapies, vaccines, biologics, and ophthalmic implants, among others.

Since our inception, we have incurred significant operating losses. Our net loss was $34.6 million and $59.8 million for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, we had an accumulated deficit of $309.6 million. We expect to incur significant expenses and operating losses for the foreseeable future as we advance product candidates through clinical trials, seek regulatory approval and pursue commercialization of any approved

66

Table of Contents

product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. In addition, we may incur expenses in connection with the in-license or acquisition of additional product candidates.

Product Pipeline

Our lead product candidate is YUTREPIA for the treatment of PAH. YUTREPIA, is an inhaled dry powder formulation of treprostinil designed to improve the therapeutic profile of treprostinil by enhancing deep lung delivery and achieving higher dose levels than current inhaled therapies while using a convenient, easy-to-use dry-powder inhaler (“DPI”). We received tentative approval of our New Drug Application (“NDA”) for YUTREPIA in November 2021.

Effective January 3, 2022 (the “Jeffs Effective Date”), Roger A. Jeffs, Ph.D. was appointed as our Chief Executive Officer, succeeding Damian deGoa, the former Chief Executive Officer. Dr. Jeffs will also continue to serve as a director on the Board.

In connection with Dr. Jeffs’ appointment, on the Jeffs Effective Date, the Company and Dr. Jeffs entered into an executive employment agreement (the “Jeffs Employment Agreement”) pursuant to which Dr. Jeffs is entitled to an annual base salary of $650,000 and is eligible to receive a discretionary annual cash bonus of up to 50% of his annualized base salary. Dr. Jeffs is also entitled to a quarterly bonus, beginning in 2023 through the end of the last calendar quarter in 2025, equal in the aggregate to the difference (only if positive) between the per share closing price of a share of common stock, $0.001 par value per share, of the Company (“Common Stock”) on the date which the Second Tranche Option (as defined below) is granted minus the per share closing price of Common Stock on the Jeffs Effective Date multiplied by 931,745.

On the Jeffs Effective Date, pursuant to the Jeffs Employment Agreement, Dr. Jeffs was granted a nonstatutory stock option entitling the purchase up to 1,682,827 shares (the “Sign-On Option”) of Common Stock, with an exercise price per share equal to the closing price of a share of Common Stock on the date of grant. Subject to the terms and conditions of the Jeffs Employment Agreement, Dr. Jeffs is also entitled to a grant of a nonstatutory stock option to purchase up to 931,745 shares (the “Second Tranche Option” and together with the Sign-On Option, the “Options”) of Common Stock, with an exercise price per share equal to the closing price of share of Common Stock on the date of grant. The Options shall (i) be granted under and subject to the terms of the Company’s 2020 Long-Term Incentive Plan (the “Plan”) and a form of nonstatutory stock option grant agreement, and (ii) be subject to the following vesting schedule: 25% of the grant will become vested and exercisable on the first anniversary of the Jeffs Effective Date, and the remaining portion of the grant will become vested and exercisable, as applicable, in equal monthly installments over the following thirty-six (36) months, subject to Dr. Jeffs’ continuous employment with the Company on each such vesting date. Notwithstanding the foregoing, in the event of a Change in Control (as defined in the Plan) then 100% of the unvested portion of the Options shall become vested and exercisable as of the closing date of such Change in Control, provided that Dr. Jeffs is actively employed with the Company on such date.

Amended and Restated Loan and Security Agreement

On January 7, 2022 (the “A&R SVB Effective Date”), we entered into an Amended and Restated Loan and Security Agreement with SVB and SVB Innovation Credit Fund VIII, L.P. (“Innovation”) (the “A&R SVB LSA”), which provides us with up to $40.0 million in term loans of which $20.0 million was funded on the A&R SVB Effective Date. The prior SVB LSA had provided up to $20.5 million in term loans of which $10.5 million had been funded as of December 31, 2021 and the A&R SVB Effective Date.

Under the terms of the A&R SVB LSA, SVB will make loans available in three tranches. Proceeds from the first tranche of $20.0 million were used to retire the loans outstanding under the prior SVB LSA and added $9.5 million of cash to the Company’s balance sheet. The first tranche also provides the option of drawing an additional $5.0 million at the

67

Table of Contents

Company’s discretion through December 31, 2022. A second tranche of $7.5 million is available to fund immediately upon receipt of final and unconditional approval for YUTREPIA by December 31, 2022. The third tranche of $7.5 million will be available through August 31, 2023, upon generating trailing six-month net product sales of YUTREPIA of $27.5 million by June 30, 2023. The debt facility will mature on December 1, 2025 and will consist of interest-only payments through December 31, 2023, unless the third tranche milestone is achieved, in which case interest-only payments will continue through December 31, 2024. The outstanding principal amount of the term loans shall accrue interest at a floating rate per annum equal to the greater of (1) seven and one-quarter of one percent (7.25%) and (2) the rate of interest per annum from time to time published in the money rates section of The Wall Street Journal plus four percent (4.0%).

As with the prior SVB LSA, the A&R SVB LSA contains customary affirmative and negative covenants, including but not limited to certain financial covenants, protection of intellectual property rights, the disposition of certain assets, and material adverse changes.

As an inducement to enter into the A&R SVB LSA, the Company issued to each of SVB, Innovation, and Innovation Credit Fund VIII-A L.P. (“Innovation Credit”) certain warrants to purchase shares of the Company’s common stock pursuant to the Warrant to Purchase Stock agreements by and between the Company and each recipient (collectively, the “SVB Warrants”). The grant of warrants under the respective SVB Warrants provided (i) SVB with the initial right to obtain 125,000 shares of the Company’s stock at an exercise price of $5.14 a share, and there is an opportunity for SVB to obtain up to 50,000 more warrants based on certain loans that may be made under the A&R SVB LSA, (ii) Innovation with the initial right to obtain 62,500 shares of the Company’s stock at an exercise price of $5.14 a share, and there is an opportunity for Innovation to obtain up to 25,000 more warrants based on certain loans that may be made under the Loan Agreement, and (iii) Innovation Credit with the initial right to obtain 62,500 shares of the Company’s stock at an exercise price of $5.14 a share, and there is an opportunity for Innovation Credit to obtain up to 25,000 more warrants based on certain loans that may be made under the Loan Agreement. The SVB Warrants provide an option for a cashless exercise.

2022 Inducement Plan

On January 25, 2022, the Board approved the adoption of the Company’s 2022 Inducement Plan (the “2022 Inducement Plan”). The 2022 Inducement Plan was recommended for approval by the Compensation Committee of the Board (the “Compensation Committee”), and subsequently approved and adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4) of the rules and regulations of The Nasdaq Stock Market, LLC (the “Nasdaq Listing Rules”).

The Board has reserved 310,000 shares of the Company's common stock for issuance pursuant to equity awards granted under the 2022 Inducement Plan, and the 2022 Inducement Plan will be administered by the Compensation Committee. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, equity awards under the 2022 Inducement Plan may only be made to an employee who has not previously been an employee or member of the Board (or any subsidiary of the Company), or following a bona fide period of non-employment by the Company (or a subsidiary of the Company), if he or she is granted such equity awards in connection with his or her commencement of employment with the Company or a subsidiary and such grant is an inducement material to his or her entering into employment with the Company or such subsidiary.

Components of Statements of Operations

Revenue

We primarily generate revenue pursuant to the Promotion Agreement, under which we share in the profit derived from the sale of Treprostinil Injection in the United States. Liquidia PAH has the exclusive rights to conduct commercial activities to encourage the appropriate use of Treprostinil Injection. On May 21, 2021 Liquidia PAH’s manufacturing partner, Chengdu Shifeng Medical Technologies LTD (“Chengdu”) began selling the RG 3ml Medication Cartridge, which may be used to supply medications to PAH patients. Following this clearance, we expect unit sales of Treprostinil Injection to increase, however, due to a reduction in the contractual profit split percentage from 80% to 50% as a result

68

Table of Contents

of achievement of predetermined cumulative sales thresholds revenues are expected to grow at a slower pace than unit sales.

Cost of Revenue

Cost of revenue consists of (i) the cost of employing a targeted sales force calling on physicians and hospital pharmacies involved in the treatment of PAH, as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection and (ii) a portion of the amortization of the intangible asset associated with the Promotion Agreement. We amortize the Promotion Agreement in a manner consistent with our recognition of the related revenue.

Research and Development Expenses

Research and development expense consists of expenses incurred in connection with the development of our product candidates. We expense research and development costs as incurred. These expenses include:

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. In the near term we expect our research and development expenses to remain consistent with the year ended December 31, 2021, however, levels of research and development spending are highly dependent upon the selection and progression of product candidates. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if ever, material net cash inflows may commence from any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with the duration and cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

69

Table of Contents

Our expenditures are subject to additional uncertainties, including the terms and timing of regulatory approvals. We may never succeed in achieving regulatory approval for any of our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, or our ability to manufacture and supply product, we could be required to expend significant additional financial resources and time on the completion of clinical development. Drug commercialization will take several years and millions of dollars in development costs.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance and legal functions, including stock-based compensation. Other general and administrative expenses include facility-related costs, patent filing and prosecution costs and professional fees for marketing, legal, auditing and tax services and insurance costs. We anticipate an increase in payroll and expense as a result of our preparation for commercial operations, especially as it relates to sales and marketing.

Other Income (Expense)

Other income (expense) is comprised primarily of interest income and expense. Interest income consists of interest earned on our cash deposits. Interest expense consists of interest charges on leases and debt. These charges include monthly recurring interest on such obligations in addition to non-cash charges. Non-cash charges include loss on extinguishment, interest accretion, expensing of debt issuance costs and amortization of discounts on long-term debt to interest expense.

Comparison of the Years Ended December 31, 2021 and 2020

The following table summarizes our results of operations:

​

​

Revenue

Revenue was $12.9 million for the year ended December 31, 2021, compared with $0.7 million for the year ended December 31, 2020. 2021 includes a full year of revenue related to the Promotion Agreement following the acquisition of Liquidia PAH in November 2020.

70

Table of Contents

Cost of Revenue

Cost of revenue was $3.0 million for the year ended December 31, 2021, compared with $0.2 million for the year ended December 31, 2020. 2021 includes a full year of Cost of revenue related to the Promotion Agreement following the acquisition of Liquidia PAH in November 2020.

Research and Development Expenses

Research and development expenses were $20.5 million for the year ended December 31, 2021 compared with $32.2 million for the year ended December 31, 2020, a decrease of $11.7 million or 36.3%. The decrease primarily related to lower expenses from our YUTREPIA clinical program, which was substantially completed prior to filing the NDA in April 2020, and lower employee and consulting expenses. During the year ended December 31, 2021, we incurred $6.6 million related to YUTREPIA compared to $17.4 million during the year ended December 31, 2020. Research and development expenses for the years ended December 31, 2021 and 2020 also included $7.6 million and $10.6 million in consulting and personnel costs, respectively. This decrease of $3.0 million was driven by lower headcount. These decreases were offset by a $0.8 million increase in stock-based compensation to $1.9 million for the year ended December 31, 2021 compared with $1.1 million for the year ended December 31, 2020 driven by the accelerated vesting of equity awards upon tentative FDA approval of YUTREPIA in November 2021.

General and Administrative Expenses

General and administrative expenses were $23.1 million for the year ended December 31, 2021, compared with $27.4 million for the year ended December 31, 2020. The decrease of $4.3 million, or 15.6%, was due to a $9.1 million decrease in consulting expenses and professional fees associated with corporate activities, a $1.1 million decrease in personnel expenses, and a $0.5 million decrease in commercial and marketing expenses. These decreases were offset by a $5.1 million increase in legal fees related to our ongoing YUTREPIA-related litigation and a $2.0 million increase in stock-based compensation expenses driven by the accelerated vesting of equity awards upon tentative FDA approval of YUTREPIA in November 2021.

Liquidity and Capital Resources

Sources of Liquidity

As of December 31, 2021 and 2020, our cash and cash equivalents were $57.5 million and $65.3 million, respectively.

We have financed our growth and operations through a combination of funds generated from revenues, the issuance of convertible preferred stock and common stock, finance leases, bank borrowings and the issuance of convertible notes. Our principal uses of cash have been for working capital requirements and capital expenditures. As of December 31, 2021, we had a cash balance of $57.5 million, stockholders’ equity of $65.3 million and an accumulated deficit of $309.6 million.

In February 2021, we entered into a Loan and Security Agreement with Silicon Valley Bank, the proceeds of which were used to pay off the approximately $9.4 million in outstanding principal and interest under previously bank borrowings. In January 2022, we entered into an Amended and Restated Loan and Security Agreement with Silicon Valley Bank and SVB Innovation Credit Fund VIII, L.P. We received a 24-month interest-only period and also have access to additional tranches of capital, pending achievement of certain milestones. See “Recent Events” for further information.

In April 2021, we entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with certain institutional, accredited investors (the “Purchasers”) for the sale by us in a private placement (the “Private Placement”) of an aggregate of 8,626,037 shares (the “Private Placement Shares”) of our common stock, at a purchase price of $2.52 per Private Placement Share. The gross proceeds from the sale of the Private Placement Shares were $21.7 million.

​

Table of Contents

In July 2020, we closed an underwritten public offering of 9,375,000 shares of our common stock at a price of $8.00 per share. The gross proceeds from the offering were $75.0 million and net proceeds were approximately $70.3 million, after deducting underwriting discounts and commissions and other offering expenses.

​

In August 2019, we entered into a sales agreement (the “ATM Agreement”) with Jefferies to issue and sell shares of our common stock, having an aggregate offering price of up to $40.0 million, from time to time during the term of the ATM Agreement, through an “at-the-market” equity offering program at our sole discretion, under which Jefferies acted as our agent and/or principal. We paid Jefferies a commission equal to 3.0% of the gross proceeds of any common stock sold through Jefferies under the ATM Agreement. During the year ended December 31, 2020, we sold 131,425 shares of our common stock for net proceeds of $0.7 million, after deducting underwriting discounts and other offering expenses under the ATM Agreement.

Future Funding Requirements

Prior to the potential FDA approval of YUTREPIA and until such time as we can generate significant revenues from its sale, if ever, we anticipate we will incur net losses and negative cash flows. We plan to focus in the near-term on preparations for the commercial launch of YUTREPIA, continuing sales of Treprostinil Injection, expanding our corporate infrastructure and continuing to invest in research and development efforts to explore additional product candidates. We may not be able to complete the development and initiate commercialization of these programs if, among others, our clinical trials are not successful or if the FDA does not approve our product candidates arising out of our current clinical trials when we expect, or at all.

Our primary uses of capital are, and we expect will continue to be, compensation and related personnel expenses, clinical costs, manufacturing process development, external research and development services, laboratory and related supplies, legal and other regulatory expenses, administrative and overhead costs and debt service. We also expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution as we prepare to potentially receive regulatory approval. Our future funding requirements will be heavily determined by the resources needed to support development of our product candidates. Additionally, as a publicly traded company we incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act, as well as rules adopted by the SEC and Nasdaq Stock Market LLC (“Nasdaq”) require public companies to implement specified corporate governance practices.

We believe based on our current operating plan and available borrowings under the A&R SVB LSA, excluding any potential contingent borrowings from the A&R SVB LSA and future YUTREPIA product revenue, that cash and cash equivalents will be sufficient to fund operations and remain in compliance with our minimum cash covenant of $27.5 million pursuant to the A&R SVB LSA into the fourth quarter of 2022. Increases in market share for Treprostinil Injection and potential YUTREPIA revenues following a successful launch if YUTREPIA receives final FDA approval, have the potential to improve our cashflow going forward. We have based these estimates on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. We expect that we may require additional capital to pursue in-licenses or acquisitions of other product candidates. Additional funds may not be available on a timely basis, on favorable terms, or at all, and such funds, if raised, may not be sufficient to enable us to continue to implement our long-term business strategy. If we are unable to generate significant revenues from the sale of YUTREPIA or unable to raise sufficient additional capital, we will need to substantially curtail our planned operations and the pursuit of our growth strategy.

We may raise additional capital through licensing activities, other business arrangements or the sale of equity or convertible debt securities. In such an event, the ownership of our existing shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights associated with holdings of our common stock.

72

Table of Contents

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceuticals, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Cash Flows

The following table summarizes our sources and uses of cash:

​

​

Operating Activities

Net cash used in operating activities decreased $20.1 million to $34.0 million for the year ended December 31, 2021, from $54.1 million for the year ended December 31, 2020. The decrease was mainly due to an increase in revenue and a decrease in research and development expenses during the year ended December 31, 2021 compared with the year ended December 31, 2020. For the year ended December 31, 2021, the net cash used in operating activities of $34.0 million was comprised of operating cash outflows before working capital changes of $21.6 million and net working capital outflows of $12.4 million. For the year ended December 31, 2020, the net cash used in operating activities of $54.1 million was comprised of operating cash outflows before working capital changes of $52.4 million and net working capital outflows of $1.7 million.

Investing Activities

Net cash used in investing activities was $0.1 million for the year ended December 31, 2021 consisting of property, plant and equipment purchases. Net cash provided by was $0.2 million for the year ended December 31, 2020 consisting of

73

Table of Contents

$1.0 million acquired from the acquisition of Liquidia PAH as well as $0.8 million in property, plant and equipment purchases.

Financing activities

Net cash provided by financing activities was $26.3 million for the year ended December 31, 2021 compared with $63.4 million provided by financing activities for the year ended December 31, 2020. During the year ended December 31, 2021, we received $21.7 million net proceeds from the Private Placement which closed on April 13, 2021, as well as $5.0 million in litigation financing deployments, which will be paid directly to attorneys involved in the UTC/Smiths Medical Litigation in the following quarter. The ongoing costs of the UTC/Smiths Medical Litigation are included as operating outflows. During the year ended December 31, 2020, we received $70.3 million from the public offering of common stock in July 2020 and $0.7 million from the sale of our common stock under our ATM facility, which was offset by $5.6 million in principal payments on our long-term debt, $1.6 million for expenses related to our sale of Private Placement Shares that closed in December 2019 and $1.1 million in principal payments on our finance leases.

Contractual Obligations and Commitments

In March 2012, the Company entered into an agreement, as amended, with Chasm Technologies, Inc. for manufacturing consulting services related to the Company’s manufacturing capabilities during the term of the agreement. The Company agreed to pay future contingent milestones and royalties on net sales totaling no more than $1,500,000, none of which has been earned as of December 31, 2021.

We enter into contracts in the normal course of business with contract service providers to assist in the performance of our research and development and manufacturing activities. Subject to required notice periods and our obligations under binding purchase orders, we can elect to discontinue the work under these agreements at any time. In addition, we have entered into a multi-year agreement with LGM Pharma, LLC (“LGM”) to produce active pharmaceutical ingredients for YUTREPIA. Under our manufacturing agreement with LGM, we are required to provide rolling forecasts, a portion of which will be considered a binding, firm order, subject to an annual minimum purchase commitment of $3.1 million for the term of the agreement. The agreement expires five years from the first marketing authorization approval of YUTREPIA. This minimum commitment was waived for the year ended December 31, 2022.

We have operating lease obligations including rental amounts due on leases of certain laboratory, manufacturing and office space and equipment under the terms of non-cancelable operating leases. These leases expire at various times through October 2026. Minimum operating lease payments are $1.2 million in 2022, $1.3 million in 2023, $1.3 million in 2024, $1.4 million in 2025 and $1.2 million in 2026.

We lease specialized laboratory equipment under finance leases expiring in 2022. Minimum finance lease payments are $0.3 million in 2022, $0.2 million in 2023, and $0.1 million in 2024.

We from time-to-time are subject to claims and litigation in the normal course of business, none of which we believe represent a risk of material loss or exposure.

We also have employment agreements with certain employees which require the funding of a specific level of payments, if certain events, such as a change in control or termination without cause, occur.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates and assumptions. Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements includes a summary of the significant accounting policies we used to prepare our consolidated financial statements. We have discussed the selection and disclosure of our critical accounting

74

Table of Contents

policies and estimates with our Audit Committee. The following is a review of our most significant policies and estimates.

Goodwill and Long-Lived Assets

Goodwill

Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. We acquired goodwill in the Merger Transaction of $3,903,282 which primarily represents the Liquidia PAH assembled workforce. On an annual basis and at various times throughout the year if impairment indicators are present, we make a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If we determine that the fair value of the reporting unit is less than its carrying amount, we will perform a quantitative analysis; otherwise, no further evaluation is necessary. As of December 31, 2021, we determined there was no impairment of goodwill (see Note 2 to the consolidated financial statements for the Goodwill accounting policy).

Long-Lived Assets

We review long-lived assets, including definite-life intangible assets, for realizability on an ongoing basis. Changes in depreciation and amortization, generally accelerated depreciation and variable amortization, are determined and recorded when estimates of the remaining useful lives or residual values of long-term assets change. We also review for impairment when conditions exist that indicate the carrying amount of the assets may not be fully recoverable. In those circumstances, we perform undiscounted operating cash flow analyses to determine if an impairment exists. When testing for asset impairment, we group assets and liabilities at the lowest level for which cash flows are separately identifiable. Any impairment loss is calculated as the excess of the asset’s carrying value over its estimated fair value. Fair value is estimated based on the discounted cash flows for the asset group over the remaining useful life or based on the expected cash proceeds for the asset less costs of disposal. Any impairment losses would be recorded in the consolidated statements of operations. To date, no such impairments have occurred.

Revenue Recognition from Promotion Agreements

We recognize revenue in accordance with Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of Topic 606 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.

In order to identify the performance obligations in a contract with a customer, we assess the promised goods or services in the contract and identify each promised good or service that is distinct. If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both.

Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. We evaluate any non-cash consideration, consideration payable to the customer, and whether consideration contains a significant financing element in determining the transaction price.

Revenue is measured based on consideration specified in a contract with a customer. We recognize revenue when we satisfy a performance obligation by transferring control over a service to a customer.

Table of Contents

On August 1, 2018, we partnered with Sandoz in a Promotion Agreement (the “Promotion Agreement”) to launch the first-to-file generic of Treprostinil Injection for the treatment of patients with PAH. Under the Promotion Agreement, we provide certain promotional and nonpromotional activities on an exclusive basis for the product in the United States of America for the treatment of PAH, in exchange for a share of Sandoz’s “Net Profits”, as defined within the Promotion Agreement. In addition, we paid Sandoz $20 million at the inception of the Promotion Agreement, in consideration for the right to conduct the promotional activities for the product. In exchange for our services, we are entitled to receive a portion of net profits based on specified profit levels associated with the product.

We determined that certain activities within the contract are within the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements. The commercialization of the product is a joint operating activity where we will provide promotional activities for Sandoz’s intellectual property and Sandoz will be responsible for items such as supply of the product, distribution to customers, managing sales, returns, and regulatory matters, and protection of patents. Both parties are active participants, each carrying out its assigned responsibilities, and participating in the joint operating activity and will share in the risks and rewards of the commercialization through the profit-sharing arrangement.

In addition, we determined that the services provided under the Promotion Agreement fall within the scope of Topic 606. While this is our first income-generating contract, the promotional activities we perform are one of the services we expect to provide as part of our ordinary activities, and we are receiving consideration for this service from Sandoz in the form of a share of net profits. We have one combined performance obligation under the Promotion Agreement, which is to perform promotional and non-promotional activities to encourage the appropriate use of the product in accordance with the product labeling and applicable law. As such, and in accordance with ASU 2018-18: Clarifying the Interaction between Topic 808 and Topic 606, we account for the entire Agreement under Topic 606.

Commitments and Contingencies

We have certain commitments and contingencies including litigation and related costs as well as potential royalties for previous manufacturing consulting services rendered. We account for such commitments and contingencies under ASC 450, Contingencies. We review known commitments and contingencies on a quarterly basis and review for possible additional commitments and contingencies. We record liabilities for those matters if and when circumstances present loss contingencies that are both probable and estimable and would exceed the current amounts established on the balance sheet. When loss contingencies are not both probable and estimable, we do not record additional liabilities on the balance sheet.

JOBS Act

As an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), we can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies.

Subject to certain conditions, as an emerging growth company, we rely on certain of these exemptions, including without limitation:

76

Table of Contents

We may take advantage of these exemptions for up to five years or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company on the date that is the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (ii) the last day of 2023; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC. We may choose to take advantage of some but not all of these exemptions. Accordingly, the information contained herein may be different from the information you receive from other public companies in which you hold stock.

Smaller Reporting Company

As a “smaller reporting company,” as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in addition to providing reduced disclosure about our executive compensation arrangements and business developments, among other reduced disclosure requirements available to smaller reporting companies, we present only two years of audited financial statements in addition to any required unaudited interim financial statements with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure.
