Rhea-AI Filing Summary

Phathom Pharmaceuticals reported strong first-quarter 2026 growth driven by its VOQUEZNA franchise but remained unprofitable. Product revenue reached $58.3 million, up from $28.5 million a year earlier, as prescription volume and prescriber adoption increased, mainly for GERD indications.

Net loss narrowed to $30.4 million from $94.3 million, helped by higher gross profit and significantly lower selling, general and administrative expenses. Phathom ended March 31, 2026 with $180.9 million in cash and cash equivalents, while carrying $175.0 million of term debt and a $380.9 million revenue interest financing liability tied to vonoprazan sales.

Insights

VOQUEZNA revenue is scaling quickly while losses and cash burn are improving, but leverage remains high.

Phathom more than doubled net product revenue to $58.3 million for the quarter as VOQUEZNA prescriptions grew, especially in GERD. Gross profit of $46.3 million indicates meaningful contribution after rebates and royalties.

Net loss fell to $30.4 million from $94.3 million as advertising and promotional spending declined and prior restructuring flowed through. However, interest expense of $15.8 million reflects substantial obligations from the $175.0 million Hercules term loan and the revenue interest financing liability, now $380.9 million.

The company held $180.9 million in cash and cash equivalents and believes this can fund operations for at least twelve months and support a target of operating profitability by Q3 2026 excluding stock-based compensation. Actual performance will depend on sustaining VOQUEZNA growth while managing covenants and milestone obligations.

revenue interest financing liability financial
"The carrying value of the revenue interest financing liability was $380.9 million"
A revenue interest financing liability is a recorded obligation that represents a lender’s right to receive a agreed slice of a company’s future sales in exchange for upfront funding. Think of it like selling a portion of future receipts to get cash now; it matters to investors because those ongoing payments reduce future cash flow and can change reported debt levels and profitability, affecting valuation and financial health.
qualified infectious disease product regulatory
"the FDA granted qualified infectious disease product, or QIDP, designation to VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK"
A qualified infectious disease product is a drug or biologic given a special regulatory label because it targets serious or life‑threatening infections and meets public‑health needs. The label brings incentives such as faster regulatory review, development tax benefits, and extra time with market exclusivity—think of it as a VIP pass and an extended storefront lease that can speed approval and delay generic competition. For investors, that can raise a candidate’s commercial value, lower development risk and make partnerships or buyouts more likely.
Non-Erosive GERD medical
"the FDA approved VOQUEZNA 10 mg tablets for the relief of heartburn associated with Non-Erosive GERD"
Non-erosive GERD is a form of acid reflux where people experience typical symptoms such as heartburn and regurgitation but endoscopic exams show no visible injury to the lining of the esophagus. Think of it like a smoke alarm going off without any visible fire — the problem causes discomfort but isn’t showing obvious tissue damage. It matters to investors because this subtype often responds differently to treatments, affects trial design and patient selection, and represents a large patient group that shapes market size, pricing and reimbursement for therapies.
New Chemical Entity exclusivity regulatory
"all three VOQUEZNA products now have NCE exclusivity extending through May 3, 2032"
potassium-competitive acid blocker medical
"vonoprazan, an oral small molecule potassium-competitive acid blocker, or PCAB"
A potassium-competitive acid blocker is a type of medication that reduces stomach acid by blocking the cellular “pump” that produces acid, using a chemical that competes with potassium to stop the pump from working. For investors, it matters because this drug class can offer faster, longer-lasting acid control than older therapies, affecting market demand, pricing power, regulatory scrutiny, and commercial potential in conditions like ulcers and reflux.

PHATHOM PHARMACEUTICALS, INC.

Notes to Condensed Unaudited Financial Statements

1. Organization, Basis of Presentation and Summary of Significant Accounting Policies

Organization

Phathom Pharmaceuticals, Inc., or the Company or Phathom, was incorporated in the state of Delaware in January 2018. The Company is a commercial-stage biopharmaceutical company focused on commercializing and developing novel treatments for gastrointestinal, or GI, diseases. The Company’s financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP.

In May 2022, the U.S. Food and Drug Administration, or FDA, approved the Company's new drug applications, or NDAs for vonoprazan triple therapy, under the brand name VOQUEZNA TRIPLE PAK, and vonoprazan dual therapy, under the brand name VOQUEZNA DUAL PAK. On October 27, 2023, the FDA approved the prior approval supplements to the Company's NDAs, for VOQUEZNA TRIPLE PAK and VOQUEZNA DUAL PAK. Additionally, on November 1, 2023, the FDA approved the Company's NDA for VOQUEZNA tablets. The Company initiated commercial launch for VOQUEZNA in the U.S. for both the Erosive GERD and H. pylori indications, and VOQUEZNA TRIPLE PAK and VOQUEZNA DUAL PAK for treatment of H. pylori infection in the fourth quarter of 2023. Additionally, on July 17, 2024, the FDA approved VOQUEZNA 10 mg tablets for the relief of heartburn associated with Non-Erosive GERD.

Liquidity and Capital Resources

From inception to March 31, 2026, the Company has devoted substantially all of its efforts to organizing and staffing the Company, business planning, raising capital, in-licensing its initial and approved product candidate, vonoprazan, meeting with regulatory authorities, managing the clinical trials of vonoprazan, preparing for commercialization of its initial products containing vonoprazan, commercially launching its approved products in the U.S., and providing other selling, general and administrative support for these operations. The Company has a limited operating history as a commercial company. Although the Company has generated product revenue to date, the amount of future sales and income potential from its business remains uncertain. The Company has incurred net losses and negative cash flows from operating activities since its inception and despite the Company's plans and expectations, could continue to incur additional net losses in the future. The Company has funded its operations primarily through commercial bank debt, the revenue interest financing debt and various equity offerings, including the Company's at-the-market, or ATM, offerings. From inception through March 31, 2026, the Company sold 41,612,032 shares of common stock and 3,859,000 pre-funded warrants, generating net proceeds of approximately $665.3 million, after deducting underwriting discounts, commissions and offering costs.

The accompanying unaudited interim condensed financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities in accordance with GAAP. Management is required to perform a two-step analysis over the Company’s ability to continue as a going concern. Management must first evaluate whether there are conditions and events that raise substantial doubt about the Company’s ability to continue as a going concern (Step 1). If management concludes that substantial doubt is raised, management is also required to consider whether its plans alleviate that doubt (Step 2).

Management believes that it has sufficient working capital on hand to fund operations through at least the next twelve months from the date these unaudited interim condensed financial statements were issued. There can be no assurance that the Company will be successful in acquiring additional funding, if needed, that the Company’s projections of its future working capital needs will prove accurate, or that any additional funding would be sufficient to continue operations in future years.

Basis of Presentation

The unaudited interim condensed financial statements included herein have been prepared by the Company in accordance with GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. In the opinion of management, the accompanying unaudited interim condensed financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the Company’s financial position, results of operations, and cash flows. The interim results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information in the footnote disclosures of the financial statements has been condensed or omitted where it substantially duplicates information provided in the Company’s latest audited financial statements, in accordance with the rules and regulations of the SEC. These unaudited interim condensed financial statements should be read in conjunction with the Company’s audited financial statements and footnotes included

F-5


 

in its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, or the 2025 Form 10-K, filed with the SEC on February 26, 2026.

During the three months ended March 31, 2026, there were no significant changes to the Company’s summary of significant accounting policies contained in the Company’s 2025 Form 10-K. The Company’s complete listing of significant accounting policies is set forth in Note 1 of the notes to the audited financial statements in the Company's 2025 Form 10-K. Selected significant accounting policies are discussed in detail below.

Use of Estimates

The preparation of the Company’s unaudited condensed interim financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities in the Company’s unaudited condensed interim financial statements and accompanying notes. The most significant estimates in the Company’s unaudited condensed interim financial statements relate to accruals for net product revenues and the valuation for the revenue interest financing liability. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results could differ materially from those estimates and assumptions.

Fair Value Measurements

The accounting guidance defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or non-recurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1: Observable inputs such as quoted prices in active markets.

Level 2: Inputs, other than the quoted prices in active markets that are observable either directly or indirectly.

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, are classified within the Level 1 designation discussed above, while accounts receivable, prepaid and other current assets, accounts payable, and accrued liabilities, approximate fair value due to their short maturities.

The Company has no financial assets measured at fair value on a recurring basis. None of the Company’s non-financial assets or liabilities are recorded at fair value on a non-recurring basis. No transfers between levels have occurred during the periods presented.

As of March 31, 2026 and December 31, 2025, the estimated fair value of the Company’s long-term debt approximated the carrying amount given its floating interest rate basis. The fair value of the Company’s long-term debt was estimated for disclosure purposes only and was determined based on quoted market data for valuation, and thus categorized as Level 2 in the fair value hierarchy.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

The Company is also subject to credit risk from our accounts receivable related to our product sales. The Company monitors exposure within accounts receivable and records an allowance for credit losses as necessary. The Company extends credit primarily to wholesale distributors. Customer creditworthiness is monitored and collateral is not required. The allowance for credit losses reflects the best estimate of expected credit losses of the accounts receivable portfolio determined on the basis of historical experience, current

F-6


 

information, and forecasts of future economic conditions. The Company determines its allowance methodology by pooling receivable balances at the customer level. The Company considers various factors, including its previous loss history, individual credit risk associated with each customer, and the current and future conditions of the general economy. These credit risk factors are monitored on a quarterly basis and updated as necessary. To the extent that any individual debtor is identified whose credit quality has deteriorated, the Company establishes allowances based on the individual risk characteristics of such customer. The Company makes concerted efforts to collect all outstanding balances due from customers; however, account balances are charged off against the allowance when management believes it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to customers.

As of March 31, 2026, three customers accounted for 81% of the accounts receivable balance, with each of these individual customers ranging from 24% to 29% of the accounts receivable balance. As of December 31, 2025, three customers accounted for 78% of the accounts receivable balance, with each of these individual customers ranging from 19% to 30% of the accounts receivable balance. For the three months ended March 31, 2026, three customers accounted for 70% of the product sales in each period, with each of these individual customers ranging from 20% to 26% of the product sales. For the three months ended March 31, 2025, three customers accounted for 76% of the product sales, with each of these individual customers ranging from 24% to 27% of the product sales.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding and pre-funded warrants outstanding for the period, without consideration for other potentially dilutive securities. For the three months ended March 31, 2026 and 2025 , basic shares outstanding includes the weighted average effect of the Company’s outstanding pre-funded warrants, the exercise of which requires little or no consideration for the delivery of shares of common stock. For the three months ended March 31, 2026 and 2025, the Company had no weighted-average unvested shares to exclude from the weighted-average number of common shares outstanding. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Dilutive common stock equivalents are comprised of unvested common stock, options and warrants. For the periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities (warrants, stock options, and restricted stock units) would be antidilutive.

Recently Adopted Accounting Standards

There were no recently adopted accounting standards which would have a material impact on the Company's unaudited interim condensed financial statements.

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03 - Disaggregation of Income Statement Expenses, which requires more detailed disclosures about specified categories of expenses (including employee compensation, depreciation, and amortization) included in certain expense captions presented on the face of the income statement. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, may be applied prospectively or retrospectively, and allows for early adoption. This standard is not expected to have an impact on any amounts recognized in our financial statements, but will result in more detailed disclosures addressing the categorization of expenses.

The Company assesses the adoption impact of recently issued accounting standards by the Financial Accounting Standards Board or other standard setting bodies on the Company's financial statements as well as material updates to previous assessments, if any, from the Company’s 2025 Form 10-K. There were no new material accounting standards issued in the first quarter of 2026 that impacted the Company.

3. Commitments and Contingencies

License Agreement

On May 7, 2019, the Company entered into a license agreement with Takeda pursuant to which it was granted an exclusive license to commercialize vonoprazan fumarate in the United States, Canada and Europe, or the Takeda License. The Company also has the right to sublicense its rights under the agreement, subject to certain conditions. The agreement will remain in effect, on a country-by-country and product-by-product basis, until the later of (i) the expiration of the last to expire valid patent claim covering vonoprazan fumarate alone or in combination with at least one other therapeutically active ingredient, (ii) the expiration of the applicable regulatory exclusivity and (iii) 15 years from the date of first commercial sale, unless earlier terminated. The Company may terminate the Takeda License upon six months’ written notice. The Company and Takeda may terminate the Takeda License in the case of the other party’s insolvency or material uncured breach. Takeda may terminate the Takeda License if the Company challenges, or assists in challenging, licensed patents.

In consideration of the Takeda License, the Company (i) paid Takeda $25 million in cash, (ii) issued Takeda 1,084,000 shares of its common stock at a fair value of $5.9 million, (iii) issued the Takeda Warrant to purchase 7,588,000 shares of its common stock at an exercise price of $0.00004613 per share at an initial fair value of $47.9 million, and (iv) issued a right to receive an additional common stock warrant, or the Takeda Warrant Right, should Takeda’s fully-diluted ownership of the Company represent less than a certain specified percentage of the fully-diluted capitalization, including shares issuable upon conversion of then outstanding convertible promissory notes, calculated immediately before the closing of the Company’s initial public offering, or IPO, with a nominal initial fair value due to the low probability of issuance. The Takeda Warrant Right expired without effect since no fair value had been allocated to it upon completion of the IPO, and no additional warrant was issued. In addition, the Company is obligated to pay Takeda up to an aggregate of $250 million in sales milestones upon the achievement of specified levels of product sales, and a low double-digit royalty rate on aggregate net sales of licensed products, subject to certain adjustments. The Takeda Warrant had an exercise price of

F-8


 

$0.00004613 per share, and was to expire on May 7, 2029 and became exercisable upon the consummation of the IPO. All Takeda Warrants were exercised by March 2022.

During the three months ended March 31, 2026 and 2025, the Company recorded $5.8 million and $2.9 million, respectively, of royalty expense under the Takeda License, of which $5.8 million is included within accrued expenses as of March 31, 2026.

Purchase Commitments

In December 2020, the Company entered into a supply agreement with Sandoz pursuant to which Sandoz will supply commercial quantities of amoxicillin capsules and clarithromycin tablets, package these antibiotics with vonoprazan, and provide in finished convenience packs which the Company sells as the VOQUEZNA DUAL PAK and the VOQUEZNA TRIPLE PAK. The supply agreement commits the Company to annual minimum purchase obligations. In March 2026, the Company entered into the second amendment to the supply agreement, or the Second Amendment, and as amended, the Amended Supply Agreement, whereby the parties agreed to the payment amount to be made by the Company to satisfy the remaining portion of the 2025 minimum purchase obligation and agreed to set the minimum purchase quantity for 2026. The parties further agreed that the determination of the minimum purchase obligation for years after 2026 would be mutually agreed by the parties at a specified time period prior to the end of the immediately preceding calendar year. In case the parties fail to reach an agreement on the minimum purchase obligation by such date, each party may terminate this agreement on twenty-four months prior written notice. The Second Amendment also included a price adjustment.

The Company incurred no expense and $0.1 million of expense under the agreement during the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, approximately €1.0 million, or approximately $1.1 million, for the 2025 minimum purchase obligation per the Amended Supply Agreement remains and for which the Company has recorded within accounts payable on the condensed balance sheets.

The Company had previously been informed by Sandoz that there could be a disruption in the supply of clarithromycin tablets, a component of the VOQUEZNA TRIPLE PAK, which could lead to a disruption in supply of the VOQUEZNA TRIPLE PAKs. Given more recent communications, however, the Company does not currently anticipate any near-term disruptions. The Company plans to continue to actively monitor the situation to determine if a supply disruption may arise in the future. The VOQUEZNA TRIPLE PAK represented approximately 1% of our total revenue for 2025. While the Company has not experienced any commercial disruption to date, any disruption for such supply would result in our inability to continue to commercialize the VOQUEZNA TRIPLE PAK. The VOQUEZNA bottles and the VOQUEZNA DUAL PAKs are not impacted, as they do not include clarithromycin.

Contingencies

In the event the Company becomes subject to claims or suits arising in the ordinary course of business, the Company would accrue a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated.

4. Lease Commitments

As of March 31, 2026, the Company had operating leases for office space in both Buffalo Grove, Illinois and Florham Park, New Jersey, with weighted average remaining lease terms of 4.2 years and 4.9 years, respectively. In September 2025, the Company entered into amendments to its lease agreements for the New Jersey office space to extend the terms of the leases through February 2031. All operating leases contain an option to extend the term for one additional five year period, which was not considered in the determination of the right-of-use asset or lease liability as the Company did not consider it reasonably certain that it would exercise such options.

The total rent expense for the three months ended March 31, 2026 and 2025 was $0.2 million and $0.3 million, respectively. Total short-term lease costs relating to leased vehicles were $1.8 million for each of the three months ended March 31, 2026 and 2025.

On September 17, 2021, or the Closing Date, the Company entered into a Loan and Security Agreement, or, the Loan Agreement, with Hercules Capital, Inc., or Hercules, in its capacity as administrative agent and collateral agent and as a lender, or, in such capacity, the Agent or Hercules, and the other financial institutions that from time to time become parties to the Loan Agreement as lenders. The Loan Agreement initially provided for term loans in an aggregate principal amount of up to $200 million under multiple tranches. The Company has entered into several amendments to the Loan Agreement since the initial advance and the current loan terms provided for in the latest amendment are described below.

On February 25, 2026, or the Fifth Amendment Closing Date, the Company entered into the Fifth Amendment to the Loan and Security Agreement, or the Fifth Loan Amendment, which, among other things, (i) provided for a new term loan advance of $175 million, or the Term Loan Advance, the proceeds of which, along with cash on the Company's balance sheet, were used to repay in full the existing secured obligations outstanding under the Loan Agreement, including principal, capitalized payment-in-kind interest, cash interest, existing final fee payments, and any applicable prepayment fees, (ii) provided for an additional loan tranche of up to $25 million which shall be available to the Company in the lenders’ discretion, (iii) extended the maturity date from December 1, 2027 to February 1, 2029, or the Maturity Date, subject to further extension to December 1, 2030 upon the achievement of a specified revenue milestone and subject to a certain pro forma liquidity test, (iv) extended the interest only period from October 2026 to December 2027, thereafter, monthly payment of interest and principal repayments at 2.5% of the aggregate original principal balance of the Term Loan Advance through the Maturity Date, with any remaining payments to be repaid in full on the Maturity Date, (v) cash interest rate set at floating rate based on the greater of (a) US WSJ Prime + 3.10% or (b) 9.85%, (vi) eliminated the payment-in-kind interest rate of 2.15% per annum, (vii) amended the prepayment charge, which is a percentage of the principal amount advanced under the Term Loans under the Fifth Loan Amendment, or each a Term Loan Advance and together, the Term Loan Advances, as follows: (a) if the Term Loan Advances are prepaid after the Fifth Amendment Closing Date but prior to the twelfth month anniversary of the Fifth Amendment Closing Date, 2.50%; (b) if the Term Loan Advances are prepaid on or after the twelfth month anniversary of the Fifth Amendment Closing Date but prior to the twenty-fourth month anniversary of the Fifth Amendment Closing Date, 2.00%; (c) if the Term Loan

F-10


 

Advances are prepaid on or after the twenty-fourth month anniversary of the Fifth Amendment Closing Date but prior to the thirty-sixth month anniversary of the Fifth Amendment Closing Date, 1.50%; (d) thereafter, 1.00%; provided that (x) any such prepayment charge shall be reduced by 50.0% if such prepayment is a result of a change in control and (y) upon any refinancing by Hercules such prepayment charge shall be waived in full; and (viii) provided for a new final payment fee which is as a percentage of the Term Loan Advance, calculated as follows: (a) if the Term Loan Advances are repaid prior to September 2027, 1.25%; (b) if the Term Loan Advances are repaid after September 1, 2027 but on or prior to February 1, 2029, 2.00%; (c) if the Term Loan Advances are repaid after February 1, 2029 but on or prior to January 1, 2030, 3.00%, and (d) if the Term Loan Advances are repaid after January 1, 2030, 3.50%. As of March 31, 2026, the Company recorded $3.5 million within other long-term liabilities for the new final payment fee based on the Term Loan Advance being repaid by the Maturity Date.

The Company accounted for the Fifth Loan Amendment in accordance with ASC 470-50, Modification and Extinguishments, or ASC 470-50, to determine if the transaction was treated as a modification or an extinguishment of debt. The Company reviewed the debt terms and determined the change would be accounted for prospectively as a partial debt extinguishment in accordance with ASC 470-50. As a result, the Company expensed a portion of the remaining deferred debt issuance costs and fees of $0.8 million associated with the debt prior to the Fifth Loan Amendment, as a loss on partial debt extinguishment within other expense, net in the condensed statements of operations and comprehensive loss for the three months ended March 31, 2026. Prior to the Fifth Loan Amendment, there were approximately $6.9 million of deferred debt issuance costs remaining to be amortized. The partial extinguishment and modification resulted in a net reduction in deferred issuance fees of $0.5 million with a remaining balance of $6.4 million in debt issuance costs capitalized to be amortized over the three year life of the new debt.

As collateral for the obligations, the Company has granted to Hercules a senior security interest in all of Company’s right, title, and interest in, to and under substantially all of Company’s property, inclusive of intellectual property.

The Loan Agreement contains customary closing fees, prepayment fees and provisions, events of default, and representations, warranties and covenants, including financial covenants. The financial covenants under the Fifth Loan Amendment include (i) a minimum cash covenant and (ii) a performance covenant as follows:

(i)
Minimum cash covenant - The Company must maintain a minimum cash balance of 20% of the outstanding principal balance at all times, which will decrease to 15% of the outstanding principal amount upon the Company reporting and maintaining $75 million of trailing three months net product revenue.
(ii)
Performance covenant - In addition, the Company must satisfy any one of the following:
a.
Market capitalization exceeding $900 million;
b.
Minimum cash balance of 50% of the outstanding principal amount of the term loans, which will decrease to 40% upon achieving $65 million of trailing three months net product revenue, and to 30% upon achieving $85 million of trailing three months net product revenue; or
c.
Trailing three months net product revenue equal to 75% of projected revenue in 2026 and 70% of projected revenue in 2027 and beyond, tested on a quarterly basis.

Upon the occurrence of an event of default, subject to any specified cure periods, all amounts owed by the Company may be declared immediately due and payable by Hercules, as collateral agent.

As of March 31, 2026, the Company was in compliance with all applicable covenants under the Loan Agreement.

In connection with the entry into the initial Loan Agreement, the Company issued to Hercules a warrant, or the Warrant, to purchase a number of shares of the Company’s common stock equal to 2.5% of the aggregate amount of the Term Loan advances. On the Closing Date, the Company issued a Warrant for 74,782 shares of common stock. The Warrant will be exercisable until September 17, 2028 (seven years from the date of issuance) at a per-share exercise price equal to $33.43, which was the closing price of the Company’s common stock on September 16, 2021. The Warrant issued with the initial tranche was not modified as part of the Fifth Loan Amendment. The exercise price and terms of the outstanding Warrant remain unchanged.

The $3.5 million of final payment fees and $1.8 million facility fee incurred as part of the Fifth Loan Amendment, along with the $6.4 million of unamortized debt issuance costs as a result of the debt modification, have been recorded as debt discount and are being amortized to interest expense using the effective interest method over the remaining term of the Loan Agreement.

During the three months ended March 31, 2026 and 2025, the Company recognized $6.5 million and $7.1 million, respectively, of interest expense, including amortization of the debt discount, in connection with the Loan Agreement. As of March 31, 2026, the Company had an outstanding loan balance of $175.0 million and accrued interest of $1.7 million.

6. Revenue Interest Financing Liability

On May 3, 2022, the Company entered into a Revenue Interest Financing Agreement with Initial Investors NovaQuest Capital Management, or NQ, Sagard Holdings Manager LP, or Sagard, and Hercules pursuant to which the Company had the right to receive up to $260 million in funding from the Initial Investors. Under the terms of the Revenue Interest Financing Agreement, the Company received $100 million at the initial closing and received an additional $160 million upon FDA approval of VOQUEZNA for treatment of Erosive GERD during the fourth quarter of 2023.

Additionally, on October 31, 2022, the Company entered into a Joinder Agreement with the Initial Investors and CO Finance LVS XXXVII LLC, or the Additional Investor, and Hercules, together as the investors. Under the terms of the Joinder Agreement, the Company received $15 million in additional funding upon FDA approval of vonoprazan for Erosive GERD, or Approval Additional Funding, during the fourth quarter of 2023, and provided for $25 million in additional funding for achievement of a sales milestone, or Milestone Additional Funding, and, together with the Approval Additional Funding, or the Additional Investor Funding. The Initial Investors waived their rights of first offer regarding the Additional Investor Funding and the Additional Investor joined the Revenue Interest Financing Agreement to extend commitments for the Additional Investor Funding. On December 23, 2024, CO Finance LVS XXXVII LLC agreed to assign and transfer to OC III LVS LX LP all of its rights, title and interest as an Additional Investor and in connection therewith, OC III LVS LX LP executed a Joinder Agreement. The total amount funded by the Initial Investors and any subsequent investors is referred to herein as the Investment Amount. As of March 31, 2026, no additional funding is available under the Revenue Interest Financing Agreement.

Under the Revenue Interest Financing Agreement, the investors are entitled to receive a 10% royalty on net sales of products containing vonoprazan. The royalty rate is subject to a step-down on net sales exceeding certain annual thresholds and when the Company received FDA approval for vonoprazan for an indication relating to the treatment of heartburn associated with Non-Erosive GERD, which occurred on July 17, 2024. The investors’ right to receive royalties on net sales will terminate when the investors have received aggregate payments equal to 200% of the Investment Amount. In addition, at any time after April 30, 2024, the Company has the right to make a cap payment equal to 200% of the Investment Amount less any royalties already paid, at which time the agreement will terminate.

If the investors have not received aggregate payments of at least 100% of the Investment Amount by December 31, 2028, and at least 200% of the Investment Amount by December 31, 2037, each a Minimum Amount, then the Company will be obligated to make a cash payment to the investors in an amount sufficient to gross the investors up to the applicable Minimum Amount. As of March 31, 2026, the aggregate payments made to investors under the Revenue Interest Financing Agreement equaled $23.1 million.

Upon the occurrence of an event of default taking place between April 1, 2025 and April 1, 2028, or after April 1, 2028, the Company is obligated to pay 1.65 times Investment Amount and 2.0 times Investment Amount, respectively, less any amounts the Company previously paid pursuant to the agreement.

Additionally, under the terms of Revenue Interest Financing Agreement, the Company is subject to a minimum cash covenant of at least (a) beginning on the date that the Hercules Loan Agreement is terminated and each day thereafter until September 30, 2026, $30 million, and (b) beginning on October 1, 2026 and on each day thereafter until September 30, 2029, a certain percentage of the minimum cash reference amount defined as the difference between the Investment Amount and the amount of all royalty payments

F-12


 

received by the Investors as of each such date as follows: (i) 50% from October 1, 2026 to September 30, 2027 (ii) 75% from October 1, 2027 to September 30, 2028, and (iii) 100% from October 1, 2028 to September 30, 2029. As of March 31, 2026, the Company was in compliance with all applicable covenants under the Revenue Interest Financing Agreement.

The Company has evaluated the terms of the Revenue Interest Financing Agreement and concluded that the features of the Investment Amount are similar to those of a debt instrument. Accordingly, the Company has accounted for the transaction as a debt obligation with interest expense based on an imputed effective rate derived from the initial carrying value of the obligation and the expected future payments. The Company recalculates the effective interest rate each period based on the current carrying value and the revised estimated future payments. As of March 31, 2026, the effective interest rate of the revenue interest financing liability was approximately 10.20%. Changes in future payments from previous estimates are included in the current and future interest expense. The carrying value of the revenue interest financing liability was $380.9 million and $377.4 million as of March 31, 2026 and December 31, 2025, respectively.

Total revenue interest financing liability consists of the following (in thousands):

During the three months ended March 31, 2026 and 2025, the Company recognized $9.3 million and $11.0 million, respectively, of interest expense in connection with the revenue interest financing liability.

The Company will record liabilities associated with achievement of the sales milestone when such contingent event occurs. To determine the accretion of the liability related to the Revenue Interest Financing Agreement, the Company is required to estimate the total amount of future royalty payments and estimated timing of such payments based on the Company’s revenue projections. As royalty payments are made, the balance of the debt obligation will be effectively repaid. Based on the Company’s periodic review, the exact timing of repayment is likely to be different in each reporting period as compared to those estimated in the Company’s initial revenue projections. A significant increase or decrease in actual net sales of vonoprazan compared to the Company’s revenue projections could impact the interest expense associated with the revenue interest financing liability. Also, the Company’s total obligation can vary depending on default events and achievement of the sales milestone.

7. Stockholders’ Equity

Common Stock

From inception through March 31, 2026, the Company sold 41,612,032 shares of common stock and 3,859,000 pre-funded warrants, generating net proceeds of approximately $665.3 million, after deducting underwriting discounts, commissions and offering costs.

F-13


 

Underwritten Public Offering

In January 2026, the Company sold 6,875,000 shares of common stock at a price of $16.00 per share and pre-funded warrants to purchase 1,250,078 shares of common stock at a price of $15.999 per pre-funded warrant, which represents the per share price for the common stock less the $0.001 per share exercise price for each such pre-funded warrant. The Company received gross proceeds of $130.0 million, before deducting underwriting discounts and commissions. The net purchase price after deducting the underwriting discounts and commissions and other offering expenses, was $15.01 per share or net proceeds of $122.0 million. Certain affiliates of Frazier Life Sciences IX, L.P., or Frazier, a significant stockholder and Dr. James Topper, who currently serves on the Company's Board of Directors, share voting and investment power of the securities held by Frazier. Frazier participated in the offering by purchasing pre-funded warrants on the same terms as all other investors at a purchase price of $15.999, which represents the per share public offering price for the common stock less the $0.001 per share exercise price for each pre-funded warrant. Each pre-funded warrant became exercisable upon issuance and will not expire until exercised in full. The pre-funded warrants may not be exercised if the aggregate number of ordinary shares beneficially owned by the holders thereof immediately following such exercise would exceed a specified beneficial ownership limitation.

The pre-funded warrants from the offering were classified as a component of equity in the Company's condensed balance sheets as they are freestanding financial instruments that are immediately exercisable, do not embody an obligation for the Company to repurchase its own shares and permit the holders to receive a fixed number of shares of common stock upon exercise. The Company valued the pre-funded warrants at issuance, concluding that their sales price approximated their fair value, and allocated net proceeds from the sale proportionately to the common stock and pre-funded warrants, of which $18.8 million was allocated to the pre-funded warrants and recorded as a component of additional paid-in capital for the three months ended March 31, 2026. As of March 31, 2026, none of the pre-funded warrants have been exercised.

ATM Offerings

In November 2020, the Company entered into an Open Market Sale AgreementSM, or the Sales Agreement, with Jefferies LLC, or the Sales Agent, under which the Company may, from time to time, sell shares of common stock having an aggregate offering price of up to an amount registered under an effective registration statement through the Sales Agent.

In November 2023, the Company filed a shelf registration statement on Form S-3 which was declared effective by the SEC on November 17, 2023, which included an at-the-market prospectus pursuant to which the Company may, from time to time, sell up to an aggregate of $150 million of the Company's common stock through the Sales Agent, or the 2023 ATM Offering. The Company is not obligated to, and cannot provide any assurances that the Company will, make any sales of the shares under the Sales Agreement. The Sales Agreement may be terminated by the Sales Agent or the Company at any time. No shares were sold during the three months ended March 31, 2026 and 2025. As of March 31, 2026, all of the available $150 million under the 2023 ATM Offering remains available.

Equity Incentive Plan

The Company’s 2019 Equity Incentive Plan, or the Prior Incentive Plan, provided for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other stock awards to eligible recipients, including employees, directors or consultants of the Company. The Company had 2,231,739 shares of common stock authorized for issuance under the Prior Incentive Plan, of which, 1,400,528 stock options and 16,260 restricted stock awards were granted in 2019. As a result of the adoption of the 2019 Incentive Award Plan, or the 2019 Plan, in October 2019, no further awards may be available for issuance under the Prior Incentive Plan.

2019 Incentive Award Plan

In October 2019, the Board of Directors adopted, and the Company’s stockholders approved, the 2019 Plan, which became effective in connection with the IPO. Under the 2019 Plan, the Company may grant stock options, stock appreciation rights, restricted stock, restricted stock units, or RSUs, performance stock units, or PSUs, and other awards to individuals who are then employees, officers, non-employee directors or consultants of the Company or its subsidiaries. The number of shares initially available for issuance will be increased by (i) the number of shares subject to stock options or similar awards granted under the Prior Incentive Plan that expire or otherwise terminate without having been exercised in full after the effective date of the 2019 Plan and unvested shares issued pursuant to awards granted under the Prior Incentive Plan that are forfeited to or repurchased by the Company after the effective date of the 2019 Plan, with the maximum number of shares to be added to the 2019 Plan pursuant to clause (i) above or equal to 1,416,788 shares, and (ii) an annual increase on January 1 of each calendar year beginning in 2020 and ending in 2029, equal to the lesser of (a) 5% of the shares of common stock outstanding on the final day of the immediately preceding calendar year and (b) such smaller number of shares as determined by the Board of Directors.

As of March 31, 2026, 3,495,959 shares remain available for issuance under the 2019 Plan, which reflects 1,859,709 stock options, RSUs and PSUs granted, and 167,340 of awards cancelled or forfeited, during the three months ended March 31, 2026 as well as an annual increase of 3,570,952 shares authorized on January 1, 2026.

2025 Employment Inducement Incentive Award Plan

On March 30, 2025, the Board of Directors adopted the 2025 Employment Inducement Incentive Award Plan, or the Inducement Plan, and reserved 2,500,000 shares of the Company’s common stock for issuance pursuant to equity awards granted under the Inducement Plan to individuals not previously employees or non-employee directors of the Company (or following such individuals’ bona fide period of non-employment with the Company) as an inducement to join the Company. The Inducement Plan provides for the grant of equity-based awards, including nonstatutory stock options, RSUs, restricted stock, stock appreciation rights, performance shares and PSUs, and its terms are substantially similar to the Company’s 2019 Plan, but with such other terms and conditions intended to comply with the Nasdaq inducement award exception or to comply with the Nasdaq acquisition and merger exception. As of March 31, 2026, the Company granted 2,090,339 stock options, RSUs and PSUs under the Inducement Plan and 409,661 shares remain available for issuance.

Performance-Based Units

In 2025, the Board of Directors approved the grant of PSUs, whereby vesting depends on certain revenue performance milestones for 2025 and over the next two years and stock price hurdle PSUs. The Company estimates the likelihood of achievement of performance milestones for all PSU awards at the end of each reporting period. To the extent those awards or portions thereof are considered probable of being achieved, such awards or portions thereof are expensed over the performance period. Recognition of stock-based compensation expense relating to the stock price hurdle PSUs commenced on the date of grant and the expense is recognized ratably over the requisite service period of the award. The stock price hurdle PSUs are considered a market condition under FASB ASC Topic 718 Compensation – Stock Compensation and is estimated on the grant date using Monte Carlo simulations. The key assumptions used in determining this valuation included an expected volatility of 86.84%, a dividend yield of zero, a risk-free interest rate of 3.67%, and an expected term of 3.75 years.

For performance milestone PSUs, stock-based compensation expense is recorded based on the market price of the Company's common stock on the grant date and is recognized if and when the achievement of such performance milestones are determined to be probable by the Company. During the three months ended March 31, 2026, a revenue performance milestone was considered probable, and the Company recognized stock-based compensation expense related to the probable vesting of PSUs. The fair value of the PSUs that vested during the three months ended March 31, 2026 was approximately $1.1 million.

As of March 31, 2026, the Company had approximately $2.7 million of related unrecognized stock-based compensation expense related to PSUs, which is expected to be recognized over a weighted-average period of approximately 1.7 years.

The total fair value of RSUs vested during the three months ended March 31, 2026, was approximately $4.0 million.

Employee Stock Purchase Plan

In October 2019, the Board of Directors adopted, and the Company’s stockholders approved, the Employee Stock Purchase Plan, or the ESPP, which became effective in connection with the IPO. The ESPP permits participants to purchase common stock through payroll deductions of up to 20% of their eligible compensation, which includes a participant’s gross base compensation for services to the Company, including overtime payments and excluding sales commissions, incentive compensation, bonuses, expense reimbursements, fringe benefits and other special payments. A total of 270,000 shares of common stock were initially reserved for issuance under the ESPP. In addition, the number of shares available for issuance under the ESPP will be annually increased on January 1 of each calendar year beginning in 2020 and ending in 2029, by an amount equal to the lesser of: (i) 1% of the shares outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares as is determined by the Board of Directors. As of March 31, 2026, 1,859,861 shares of common stock remain available for issuance under the ESPP, which includes the 211,837 shares sold to employees during the three months ended March 31, 2026 as well as an annual increase of 714,190 shares authorized on January 1, 2026.

F-16


 

The ESPP is considered a compensatory plan, and for the three months ended March 31, 2026 and 2025, the Company recorded related stock-based compensation of $0.2 million and $0.3 million, respectively. The weighted-average assumptions used to estimate the fair value of ESPP awards using the Black-Scholes option valuation model were as follows:

The estimated weighted-average fair value of ESPP awards for the three months ended March 31, 2026 and 2025, was $4.85 and $2.81, respectively. As of March 31, 2026, the total unrecognized compensation expense related to the ESPP was $0.4 million, which is expected to be recognized over a weighted-average period of approximately 0.3 years.

401(k) Plan

During 2020, the Company established a 401(k) savings plan. The Company’s contributions to the plan are discretionary. During the three months ended March 31, 2026 and 2025, the Company incurred $1.6 million and $1.8 million, respectively, of expense related to estimated employer contribution liabilities, which was based on a 75% match of employees’ contributions during the periods. During the three months ended March 31, 2026 and 2025, the Board of Directors approved employer matching contributions settled by contributing 132,035 and 290,165, respectively, shares of common stock.

Stock Options

The fair value of each employee and non-employee stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company, prior to the IPO on October 29, 2019, was a private company and lacked company-specific historical and implied volatility information. Therefore, the Company estimated its expected volatility based on the historical volatility of a publicly traded set of peer companies. Due to the lack of historical exercise history, the expected term of the Company’s stock options for employees was determined utilizing the “simplified” method for awards. The expected term of stock options granted to non-employees was equal to the contractual term of the option award. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield was zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

8. Revenue Recognition

To date, our only source of revenue has been from the U.S. sales of VOQUEZNA products, which the Company began selling during the fourth quarter of 2023. The Company records its best estimate of chargebacks, sales discounts and other reserves to which customers are likely expected to be entitled to as contra accounts receivable charges, and within accrued expenses if payable to a third-party or related to product returns on the condensed balance sheets. During the three months ended March 31, 2026 and 2025, the Company recognized $58.3 million and $28.5 million, respectively, of net product revenues related to sales of VOQUEZNA, VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK.

9. Segment Information

The Company's chief operating decision maker, or CODM, the Chief Executive Officer, manages the Company’s business activities as a single reportable segment. The segment derives its current revenues from the sale of VOQUEZNA products. Accordingly, the CODM uses net income (loss) to measure segment profit or loss, allocate resources and assess performance. Further, the CODM reviews and utilizes functional expenses (research and development, general and administrative, sales and marketing and stock-based compensation) to manage the Company’s operations. Other segment items included in net loss are interest income, interest expense and other expense, which are reflected in the condensed statements of operations and comprehensive loss. The measure of segment assets is reported on the condensed balance sheets as total assets.

In May 2025, the Company implemented a cost reduction and organizational restructuring plan to reduce cash burn and focus resources on commercial execution. In connection with the restructuring, the Company's workforce was reduced by 26 employees, or approximately 6%, including certain leadership changes all designed to right-size the organization. In 2025, the Company incurred restructuring charges of $9.2 million consisting of one-time termination benefits to affected employees for severance, non-cash stock-based compensation costs, healthcare benefits and outplacement assistance. The costs were included in research and development and selling, general, and administrative expenses on the Company’s condensed consolidated statement of operations and comprehensive loss.

Overview

We are a commercial-stage biopharmaceutical company focused on commercializing and developing novel treatments for gastrointestinal, or GI, diseases. Our approved products, VOQUEZNA®, VOQUEZNA® DUAL PAK® and VOQUEZNA® TRIPLE PAK®, contain vonoprazan, an oral small molecule potassium-competitive acid blocker, or PCAB. PCABs are a novel class of molecules that block acid secretion in the stomach. VOQUEZNA is the only PCAB currently approved for marketing and sale in the United States.

We began U.S. commercialization of VOQUEZNA for the treatment of erosive gastroesophageal reflux disease, or Erosive GERD, and Helicobacter pylori, or H. pylori, infection, and VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK for the treatment of H. pylori infection in November 2023. The U.S. Food and Drug Administration, or FDA, approved VOQUEZNA for the relief of heartburn associated with Non-Erosive GERD, the largest category of GERD, in July 2024.

Vonoprazan was originally developed by Takeda Pharmaceutical Company Limited, or Takeda, and is marketed in multiple countries outside the United States. We licensed U.S., European and Canadian rights to vonoprazan from Takeda in 2019. We are independently commercializing VOQUEZNA, VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK in the United States.

During the three months ended March 31, 2026, we generated increased revenues from sales of our VOQUEZNA products compared to same period in the prior year, reflecting continued execution of our U.S. commercial strategy. The majority of our revenue was derived from sales of VOQUEZNA. During this period, we also experienced growth in prescription volume and prescriber adoption, with most prescriptions written for GERD indications. As of April 17, 2026, approximately 1.35 million prescriptions for VOQUEZNA, VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK have been filled since launch. We continue to have broad commercial coverage for VOQUEZNA, with access for over 120 million, or over 80%, of U.S. commercial lives. Our commercial efforts are supported by a targeted sales force and continued focus on prescriber engagement and payer access.

In May 2021, the FDA granted qualified infectious disease product, or QIDP, designation to VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK, resulting in an extension of the five-year new chemical entity, or NCE, exclusivity by an additional five years.

 

22


 

In December 2024, we submitted a citizen petition requesting that the FDA update the Orange Book listing for VOQUEZNA to reflect the same ten-year period of NCE exclusivity applicable to VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK. In June 2025, the FDA granted the petition and updated the Orange Book listing for VOQUEZNA to reflect the ten-year period of NCE exclusivity for vonoprazan. As a result, all three VOQUEZNA products now have NCE exclusivity extending through May 3, 2032.

In the fourth quarter of 2025, we initiated a Phase 2 clinical trial evaluating vonoprazan in the treatment of adults with eosinophilic esophagitis, or EoE. While our current focus is on continued U.S. commercialization of VOQUEZNA products for GERD and H. pylori, we are also selectively pursuing life-cycle management opportunities for vonoprazan. We may also explore the potential for vonoprazan in Europe and Canada, as well as opportunities to in-license or acquire additional clinical or commercial-stage product candidates for GI diseases.

We commenced our operations in 2018 and have devoted substantially all of our resources to date to organizing and staffing our company, business planning, raising capital, in-licensing vonoprazan, meeting with regulatory authorities, managing our clinical trials of vonoprazan, preparing for commercialization of our products containing vonoprazan, commercially launching our approved products in the U.S., and providing other selling, general and administrative support for our operations. Our operations to date have been funded primarily through commercial bank debt, our revenue interest financing debt and various equity offerings, including our at-the-market offerings. From inception through March 31, 2026, we sold 41,612,032 shares of common stock and 3,859,000 pre-funded warrants, generating net proceeds of approximately $665.3 million, after deducting underwriting discounts, commissions and offering costs.

As of March 31, 2026, we had cash and cash equivalents of $180.9 million. Based on our current operating plan, we believe that our existing cash and cash equivalents together with our anticipated product revenues, are sufficient to fund operations for at least the next twelve months and will be sufficient to enable us to reach operating profitability beginning in the third quarter of 2026, excluding stock-based compensation. We have based these estimates on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our operating plans and other demands on our cash resources may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings or other capital sources, including potentially collaborations, licenses and other similar arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. Attempting to secure additional financing may divert our management from our day-to-day activities, which may adversely affect our ability to commercialize VOQUEZNA, develop vonoprazan for additional indications or formulations or develop or any future product candidates.

Since inception, we have incurred significant operating losses. Our net losses were $30.4 million and $94.3 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, we had an accumulated deficit of $1.5 billion. Despite our plans and expectations, we could continue to incur operating losses for the foreseeable future. If we do not achieve our goals, it could be several years, if ever, before our current products or potential future product candidates, if successfully developed and approved, generate significant revenues to offset these operating losses. As a result, we are uncertain if we will achieve profitability on our current expected timeline, if at all, and, if so, whether we will be able to sustain it. The net losses we incur may fluctuate significantly from quarter to quarter and year to year.

While we have generated revenue to date, until such time as we can generate significant revenue from sales of our approved products containing vonoprazan, we also expect to finance our cash needs through equity offerings, additional debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when and if needed on favorable terms or at all, and this risk could be exacerbated by the impact of ongoing conflicts throughout the world and global economic conditions. Our failure to raise capital or enter into such other arrangements when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Restructuring

In May 2025, we implemented a cost reduction and organizational restructuring plan to reduce cash burn and focus resources on commercial execution. In connection with the restructuring, our workforce was reduced by 26 employees, or approximately 6%, including certain leadership changes all designed to right-size the organization. In 2025, total restructuring charges incurred were $9.2 million consisting of one-time termination benefits to affected employees for severance, non-cash stock-based compensation costs, healthcare benefits and outplacement assistance. As of March 31, 2026, approximately $0.2 million of restructuring related accruals remain on the condensed balance sheets.

License Agreement with Takeda

On May 7, 2019, we and Takeda entered into an exclusive license, or the Takeda License, pursuant to which we in-licensed the U.S., European, and Canadian rights to vonoprazan fumarate. During the term of the Takeda License, we and our affiliates are not permitted to commercialize any pharmaceutical product, other than vonoprazan, that treats acid-related disorders, except for certain generic and OTC competing products in specified circumstances. We are responsible at our cost for the development, manufacture and commercialization of vonoprazan products. We are required to use commercially reasonable efforts to develop and commercialize the vonoprazan products in our licensed territory.

Under the Takeda License, Takeda has the sole right and authority, with our input, to prepare, file, prosecute, and maintain all Takeda and joint patents on a worldwide basis at its own cost. We are responsible, at our cost, for preparing, filing, prosecuting, and maintaining patents on inventions made solely by us in connection with vonoprazan, subject to input from Takeda.

We paid Takeda upfront consideration consisting of a cash fee of $25 million, 1,084,000 shares of our common stock, a warrant to purchase 7,588,000 shares of our common stock at an exercise price of $0.00004613 per share, or the Takeda Warrant, and issued Takeda a right to receive an additional common stock warrant, or the Takeda Warrant Right, if Takeda’s fully-diluted ownership of the Company represented less than a certain specified percentage of the fully-diluted capitalization, including shares issuable upon conversion of then outstanding convertible promissory notes, calculated immediately prior to the closing of our IPO. The Takeda Warrant Right expired without effect since no fair value had been allocated to it upon completion of our IPO, and no additional warrant was issued. We agreed to make milestone payments to Takeda upon achieving certain tiered aggregate annual net sales of licensed products in the United States, Europe and Canada up to a total maximum milestone amount of $250 million. We also agreed to make tiered royalty payments at percentages averaging in the low double digits on net sales of licensed products, subject to specified offsets and reductions. Royalties are payable, on a product-by-product and country-by-country basis from the first commercial sale of such product in such country, until the latest of expiration of the licensed patents covering the applicable product, expiration of regulatory exclusivity in such country, or 15 years following first commercial sale in such country. We currently pay royalties to Takeda on sales of VOQUEZNA tablets, VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK in the U.S. During the three months ended March 31, 2026 and 2025, the Company recorded $5.8 million and $2.9 million, respectively, of royalty expense under the Takeda License, of which $5.8 million is included within accrued expenses as of March 31, 2026.

Components of Results of Operations

Revenue

We began to recognize revenue from product sales, net of rebates, chargebacks, discounts, and other adjustments, in November 2023 in conjunction with the commercial launch of VOQUEZNA, VOQUEZNA TRIPLE PAK, and VOQUEZNA DUAL PAK in the United States.

Cost of Revenue

Cost of revenue includes the cost of producing and distributing inventories that are related to product sales. This also includes royalties payable to Takeda, pursuant to the Takeda License Agreement (Refer to Note 3 for further details). In addition, shipping and handling costs for product sales along with fulfillment costs are recorded as incurred. Cost of revenue also includes costs related to excess or obsolete inventory adjustment charges.

Operating Expenses

Research and Development

To date, our research and development expenses have related to the development of vonoprazan. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received. We do not track total research and development expenses by indication.

Research and development expenses include:

Clinical development expenses: external research and development expenses incurred under agreements with clinical research organizations, regulatory costs, and consultants to conduct and support our clinical trials of vonoprazan;
Personnel related expenses: salaries, payroll taxes, and employee benefits, and restructuring expenses in 2025;
Chemistry manufacturing and controls, or CMC, expenses: costs related to the manufacturing of vonoprazan for our clinical trials;
Consulting, professional and other costs: external costs related to consulting and professional services and other research costs incurred; and
Stock-based compensation expenses: stock-based compensation expense recognized for those individuals involved in research and development efforts including for any restructuring expenses in 2025.

The following table summarizes our research and development expenses for the three months ended March 31, 2026 and 2025 (in thousands):

We plan to invest in our research and development expenses for the foreseeable future as we continue the development of vonoprazan and potentially in the future also develop additional product candidates. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future clinical trials and nonclinical studies of vonoprazan or any future product candidates due to the inherently unpredictable nature of clinical and preclinical development. Clinical and preclinical development timelines, the probability of success, actual results and development costs can differ materially from expectations. In addition, we cannot forecast which product candidates, if any, may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

Selling, General and Administrative

Selling, general and administrative expenses consist of salaries and employee-related costs, including stock-based compensation, for personnel in commercial, executive, finance, accounting, legal, human resources and other administrative functions, restructuring expenses in 2025, legal fees relating to intellectual property and corporate matters, and professional fees for accounting and consulting services.

Interest Income

Interest income consists of interest on our money market funds.

Interest Expense

Revenue Interest Financing Agreement

Interest expense under the Revenue Interest Financing Agreement is based on the imputed effective interest rate derived from expected future payments and the carrying value of the obligation. We recalculate the effective interest rate each period based on the current carrying value and the revised estimated future payments. Changes in future payments from previous estimates are included in current and future interest expense.

Loan Agreement with Hercules

Beginning on February 25, 2026, interest expense under our Loan and Security Agreement, or the Loan Agreement, with Hercules Capital, Inc., or Hercules, consists of (i) cash interest at a variable annual rate equal to the greater of (a) 9.85% and (b) the Prime Rate (as reported in the Wall Street Journal) plus 3.10%, and (ii) amortization of the Loan Agreement debt discount recorded in connection with the fair value of warrants issued to the lenders, the debt issuance costs incurred, and the obligation to make a final payment.

From December 14, 2023 through February 25, 2026, interest expense under the Loan Agreement consisted of (i) cash interest at a variable annual rate equal to the greater of (a) 9.85% and (b) the Prime Rate (as reported in the Wall Street Journal) plus 1.35% and provided that the cash interest rate was to be capped at 10.35% and upon us achieving the certain milestones, the cash interest was to decrease by 0.35%, (ii) payment-in-kind interest was at a per annum rate of interest equal to 2.15%, and (iii) amortization of the Loan Agreement debt discount recorded in connection with the fair value of warrants issued to the lenders, the debt issuance costs incurred, and the obligation to make a final payment.

Revenue. Product revenues were $58.3 million and $28.5 million for the three months ended March 31, 2026 and 2025, respectively, related to sales of VOQUEZNA, VOQUEZNA TRIPLE PAK, and VOQUEZNA DUAL PAK which were launched in the fourth quarter of 2023. The increase of $29.8 million was due to continued execution of our commercial strategy.

Cost of Revenue. Cost of revenue were $12.0 million and $3.7 million for the three months ended March 31, 2026 and 2025, respectively. The increase of $8.3 million was due to the increase in revenues and the corresponding increase in Takeda royalty payments, as well as increased fulfillment costs for the three months ended March 31, 2026.

 

 

26


 

Research and Development Expenses. Research and development expenses were $7.8 million and $9.2 million for the three months ended March 31, 2026 and 2025, respectively. The decrease of $1.4 million consists of $1.0 million related to lower personnel-related expenses and $1.0 million of lower CMC costs offset by an increase of $0.6 million of clinical development and regulatory costs.

Selling, General and Administrative Expenses. Selling, general and administrative expenses were $54.0 million and $94.5 million for the three months ended March 31, 2026 and 2025, respectively. The decrease of $40.5 million was primarily related to a $36.9 million reduction in advertising and promotional expenses, $2.3 million of lower personnel-related expenses, and $1.3 million of lower consulting and professional fees.

Other (Expense) Income. Other expense of $14.9 million for the three months ended March 31, 2026 consisted of $15.8 million of interest expense under the Loan Agreement and Revenue Interest Financing Agreement, $0.8 million partial loss on extinguishment of debt recognized under the Loan Agreement, partially offset by $1.7 million of interest income related to cash held in money market funds. Other expense of $15.5 million for the three months ended March 31, 2025 consisted of $18.1 million of interest expense under the Loan Agreement and Revenue Interest Financing Agreement, partially offset by $2.6 million of interest income related to cash held in money market funds.

Liquidity and Capital Resources

We have incurred net losses and negative cash flows from operations since our inception and while we expect to continue to incur a net loss in the near term, we anticipate achieving operating profitability beginning in the third quarter of 2026, excluding stock-based compensation. As of March 31, 2026, we had cash and cash equivalents of $180.9 million.

Loan Agreement with Hercules

On September 17, 2021, or the Closing Date, we entered into the Loan Agreement with Hercules, in its capacity as administrative agent and collateral agent and as a lender, or, in such capacity, the Agent or Hercules, and the other financial institutions that from time to time become parties to the Loan Agreement as lenders. The Loan Agreement initially provided for term loans in an aggregate principal amount of up to $200 million under multiple tranches. We entered into several amendments to the Loan Agreement since the initial advance and the current loan terms provided for in the latest amendment are described below.

On February 25, 2026, or the Fifth Amendment Closing Date, we entered into the Fifth Amendment to the Loan and Security Agreement, or the Fifth Loan Amendment, which, among other things, (i) provided for a new term loan advance of $175 million, or the Term Loan Advance, the proceeds of which, along with cash on our balance sheet, were used to repay in full the existing secured obligations outstanding under the Loan Agreement, including principal, capitalized payment-in-kind interest, cash interest, existing final fee payments, and any applicable prepayment fees, (ii) provided for an additional loan tranche of up to $25 million which shall be available to us in the lenders’ discretion, (iii) extended the maturity date from December 1, 2027 to February 1, 2029, or the Maturity Date, subject to further extension to December 1, 2030 upon the achievement of a specified revenue milestone and subject to a certain pro forma liquidity test, (iv) extended the interest only period from October 2026 to December 2027, thereafter, monthly payment of interest and principal repayments at 2.5% of aggregate original principal balance of the Term Loan Advance through the Maturity Date, with any remaining payments to be repaid in full on the Maturity Date, (v) cash interest rate set at floating rate based on the greater of (a) US WSJ Prime + 3.10% or (b) 9.85%, (vi) eliminated the payment-in-kind interest rate of 2.15% per annum, (vii) amended the prepayment charge, which is a percentage of the principal amount advanced under the Term Loans under the Fifth Loan Amendment, or each a Term Loan Advance and together, the Term Loan Advances, as follows: (a) if the Term Loan Advances are prepaid after the Fifth Amendment Closing Date but prior to the twelfth month anniversary of the Fifth Amendment Closing Date, 2.50%; (b) if the Term Loan Advances are prepaid on or after the twelfth month anniversary of the Fifth Amendment Closing Date but prior to the twenty-fourth month anniversary of the Fifth Amendment Closing Date, 2.00%; (c) if the Term Loan Advances are prepaid on or after the twenty-fourth month anniversary of the Fifth Amendment Closing Date but prior to the thirty-sixth month anniversary of the Fifth Amendment Closing Date, 1.50%; (d) thereafter, 1.00%; provided that (x) any such prepayment charge shall be reduced by 50.0 percent if such prepayment is a result of a change in control and (y) upon any refinancing by Hercules such prepayment charge shall be waived in full; and (viii) provided for a new final payment fee which is as a percentage of the Term Loan Advance, calculated as follows: (a) if the Term Loan Advances are repaid prior to September 2027, 1.25%; (b) if the Term Loan Advances are repaid after September 1, 2027 but on or prior to February 1, 2029, 2.00%; (c) if the Term Loan Advances are repaid after February 1, 2029 but on or prior to January 1, 2030, 3.00%, and (d) if the Term Loan Advances are repaid after January 1, 2030, 3.50%. As of March 31, 2026, we recorded $3.5 million within other long-term liabilities for the new final payment fee based on the Term Loan Advance being repaid by the Maturity Date.

 

27


 

We accounted for the Fifth Loan Amendment in accordance with ASC 470-50, Modification and Extinguishments, or ASC 470-50, to determine if the transaction was treated as a modification or an extinguishment of debt. We reviewed the debt terms and determined the change would be accounted for prospectively as a partial debt extinguishment in accordance with ASC 470-50. As a result, we expensed a portion of the remaining deferred debt issuance costs and fees of $0.8 million associated with the debt prior to the Fifth Loan Amendment, as a loss on partial debt extinguishment within other expense, net in the condensed statements of operations and comprehensive loss for the three months ended March 31, 2026. Prior to the Fifth Loan Amendment, there were approximately $6.9 million of deferred debt issuance costs remaining to be amortized. The partial extinguishment and modification resulted in a net reduction in deferred issuance fees of $0.5 million with a remaining balance of $6.4 million in debt issuance costs capitalized to be amortized over the three year life of the new debt.

As collateral for the obligations, we granted to Hercules a senior security interest in all of our right, title, and interest in, to and under substantially all of our property, inclusive of intellectual property.

The Loan Agreement contains customary closing fees, prepayment fees and provisions, events of default, and representations, warranties and covenants, including financial covenants. The financial covenants under the Fifth Loan Amendment include (i) a minimum cash covenant and (ii) a performance covenant as follows:

(i)
Minimum cash covenant - We must maintain a minimum cash balance of 20% of the outstanding principal balance at all times, which will decrease to 15% of the outstanding principal amount upon us reporting and maintaining $75 million of trailing three months net product revenue.
(ii)
Performance covenant - In addition, we must satisfy any one of the following:
a.
Market capitalization exceeding $900 million;
b.
Minimum cash balance of 50% of the outstanding principal amount of the term loans, which will decrease to 40% upon achieving $65 million of trailing three months net product revenue, and to 30% upon achieving $85 million of trailing three months net product revenue; or
c.
Trailing three months net product revenue equal to 75% of projected revenue in 2026 and 70% of projected revenue in 2027 and beyond, tested on a quarterly basis.

Upon the occurrence of an event of default, subject to any specified cure periods, all amounts owed by us may be declared immediately due and payable by Hercules, as collateral agent.

As of March 31, 2026, we were in compliance with all applicable covenants under the Loan Agreement.

In connection with the entry into the initial Loan Agreement, we issued to Hercules a warrant, or the Warrant, to purchase a number of shares of our common stock equal to 2.5% of the aggregate amount of the Term Loan advances. On the Closing Date, the we issued a Warrant for 74,782 shares of common stock. The Warrant will be exercisable until September 17, 2028 (seven years from the date of issuance) at a per-share exercise price equal to $33.43, which was the closing price of our common stock on September 16, 2021. The Warrant issued with the initial tranche was not modified as part of the Fifth Loan Amendment. The exercise price and terms of the outstanding Warrant remain unchanged.

The $3.5 million of final payment fees and $1.8 million facility fee incurred as part of the Fifth Loan Amendment, along with the $6.4 million of unamortized debt issuance costs as a result of the debt modification, have been recorded as debt discount and are being amortized to interest expense using the effective interest method over the remaining term of the Loan Agreement.

Revenue Interest Financing Agreement

On May 3, 2022, we entered into a Revenue Interest Financing Agreement, or the Revenue Interest Financing Agreement, with entities managed or advised by NovaQuest Capital Management, or NQ, Sagard Holdings Manager LP, or Sagard, and Hercules, together with NQ and Sagard, or the Initial Investors, pursuant to which we had the right to receive up to $260 million in funding from the Initial Investors. Under the terms of the Revenue Interest Financing Agreement, we received $100 million at the initial closing and received an additional $160 million upon FDA approval of vonoprazan for treatment of Erosive GERD in the fourth quarter of 2023. Additionally, on October 31, 2022, we entered into a Joinder and Waiver Agreement with the Initial Investors and CO Finance LVS XXXVII LLC, or the Additional Investor, and Hercules in its capacity as administrative agent and collateral agent for itself and the lenders under that certain Loan Agreement, or the Joinder Agreement, in respect of the Revenue Interest Financing Agreement. Under the terms of the Joinder Agreement, we received $15 million in additional funding upon FDA approval of

 

28


 

vonoprazan for Erosive GERD, or Approval Additional Funding, in the fourth quarter of 2023 and provided for $25 million in additional funding for achievement of a sales milestone, or Milestone Additional Funding, and, together with the Approval Additional Funding, or the Additional Investor Funding. The Initial Investors waived their right of first offer for any Additional Investor Funding. On December 23, 2024, CO Finance LVS XXXVII LLC agreed to assign and transfer to OC III LVS LX LP all of its rights, title and interest as an Additional Investor and in connection therewith, OC III LVS LX LP executed a Joinder Agreement. The total amount funded by the Initial Investors and any subsequent investors is referred to herein as the Investment Amount. As of March 31, 2026, no additional funding is available under the Revenue Interest Financing Agreement.

Under the Revenue Interest Financing Agreement, the Initial Investors and the Additional Investors, are entitled to receive a 10% royalty on net sales of products containing vonoprazan. The royalty rate is subject to a step-down on net sales exceeding certain annual thresholds and upon FDA approval for vonoprazan for an indication relating to the treatment of heartburn associated with Non-Erosive GERD, which occurred on July 17, 2024. The investors’ right to receive royalties on net sales will terminate when the investors have aggregate payments equal to 200% of the Investment Amount. In addition, at any time after April 30, 2024, we have the right to make a cap payment equal to 200% of the Investment Amount less any royalties already paid, at which time the agreement will terminate.

If the investors have not received aggregate payments of at least 100% of the Investment Amount by December 31, 2028, and at least 200% of the Investment Amount by December 31, 2037, each a Minimum Amount, then we will be obligated to make a cash payment to the investors in an amount sufficient to gross the investors up to the applicable Minimum Amount. As of March 31, 2026, the aggregate payments made to investors under the Revenue Interest Financing Agreement equaled $23.1 million.

Upon the occurrence of an event of default taking place between April 1, 2025 and April 1, 2028, or after April 1, 2028, we are obligated to pay 1.65 times Investment Amount and 2.0 times Investment Amount, respectively, less any amounts we previously paid pursuant to the agreement.

Additionally, under the terms of Revenue Interest Financing Agreement, we are subject to a minimum cash covenant of at least (a) beginning on the date that the Hercules Loan Agreement is terminated and each day thereafter until September 30, 2026, $30 million, and (b) beginning on October 1, 2026 and on each day thereafter until September 30, 2029, a certain percentage of the minimum cash reference amount defined as the difference between the Investment Amount and the amount of all royalty payments received by the Investors as of each such date as follows: (i) 50% from October 1, 2026 to September 30, 2027 (ii) 75% from October 1, 2027 to September 30, 2028, and (iii) 100% from October 1, 2028 to September 30, 2029. As of March 31, 2026, we are in compliance with all applicable covenants under the Revenue Interest Financing Agreement.

At-the-Market-Offerings

In November 2020, we entered into an Open Market Sale AgreementSM, or the Sales Agreement, with Jefferies LLC, or the Sales Agent, under which we may, from time to time, sell shares of our common stock having an aggregate offering price of up to an amount registered under an effective registration statement through the Sales Agent.

In November 2023, we filed a shelf registration statement on Form S-3 which was declared effective by the SEC on November 17, 2023, which included an at-the-market prospectus pursuant to which we may, from time to time, sell up to an aggregate of $150 million of our common stock through the Sales Agent, or the 2023 ATM Offering. We are not obligated to, and we cannot provide any assurances that we will, make any sales of the shares under the Sales Agreement. The Sales Agreement may be terminated by the Sales Agent or us at any time. No shares were sold during the three months ended March 31, 2026 and 2025. As of March 31, 2026, all of the available $150 million under the 2023 ATM Offering remains available.

Underwritten Public Offerings

On January 9, 2026, we sold 6,875,000 shares of common stock at a price of $16.00 per share and pre-funded warrants to purchase 1,250,078 shares of common stock at a price of $15.999 per pre-funded warrant for total gross proceeds of $130.0 million, before deducting underwriting discounts, commissions and offering costs. The net purchase price after deducting the underwriting discounts and commissions and other offering expenses, was $15.01 per share or net proceeds of $122.0 million.

Funding Requirements

Based on our current operating plan, we believe that our existing cash and cash equivalents together with anticipated product revenues, are sufficient to fund operations for at least the next twelve months. However, our forecast of the period of time through

 

29


 

which our financial resources may be adequate to support our operations is a forward-looking statement that involves risks and uncertainties and actual results could vary materially. We have based this estimate on assumptions that may prove to be inaccurate, and we could deplete our capital resources sooner than we expect based on the amount and timing of product sales and operating expenses, among other factors. Additionally, the process of testing product candidates in clinical trials is costly, and the timing of progress and expenses in ongoing and future trials is uncertain.

Our future capital requirements will depend on many factors, including:

our ability to achieve and maintain market acceptance, market share, coverage, reimbursement and revenues from sales of VOQUEZNA in its approved GERD indications, and patients’ willingness to pay out-of-pocket in the absence of coverage and/or adequate reimbursement from third-party payers;
the costs of sales and marketing activities in support of the continued commercialization of VOQUEZNA, VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK, or any future product candidates we may choose to pursue, if successfully developed and approved;
the costs, timing and availability of manufacturing for vonoprazan as well as the costs of manufacturing for any potential product candidates we may pursue in the future;
the initiation, type, number, scope, results, costs and timing of our clinical trials of vonoprazan, and preclinical studies or clinical trials of other potential product candidates we may choose to pursue in the future, including feedback received from regulatory authorities;
the costs, timing and outcome of regulatory review of future vonoprazan applications or such applications for any future product candidates;
the costs of obtaining, maintaining and enforcing our patents and other intellectual property rights, and the success of our enforcement efforts;
the timing of market introduction, profile and impact of competitive products;
the costs associated with hiring additional personnel and consultants as our business grows and enhancing our operational systems;
the timing and amount of the milestone or other payments we must make to Takeda and any future licensors;
the timing and impact of our obligations under our Loan and Security Agreement with Hercules Capital, Inc., and our Revenue Interest Financing Agreement; and
the costs associated with building a portfolio of product candidates through the acquisition or in-license of additional product candidates or technologies, including the terms and timing of establishing and maintaining future collaborations, licenses and other similar arrangement and the costs associated with development of any products or technologies that we may in-license or acquire.

Until such time, if ever, as we can generate substantial product revenues to support our cost structure, we expect to also finance our cash needs through equity offerings, debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our common stock. If we are unable to raise additional funds through equity or debt financings when and if needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.

Including our existing cash and cash equivalents, we believe that we have sufficient working capital on hand to fund operations such that there is no substantial doubt as to our ability to continue as a going concern at the date the unaudited interim condensed financial statements were issued. There can be no assurance that we will be successful in acquiring additional funding, that our projections of future revenues or working capital needs will prove accurate, or that any additional funding would be sufficient to continue operations in future years.

Contractual Obligations and Commitments

There were no material changes outside the ordinary course of our business during the three months ended March 31, 2026 to the information regarding our contractual obligations that was disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2025 Form 10-K.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our financial statements and

 

31


 

accompanying notes. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

For a description of our critical accounting policies, please see the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Significant Judgments and Estimates” contained in our 2025 Form 10-K. There have not been any material changes to the critical accounting policies discussed therein during the three months ended March 31, 2026.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this quarterly report. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

FAQ

How did Phathom Pharmaceuticals (PHAT) perform financially in Q1 2026?

Phathom reported Q1 2026 net product revenue of $58.3 million, up from $28.5 million a year earlier. Net loss narrowed to $30.4 million versus $94.3 million, as higher VOQUEZNA sales and lower selling and marketing expenses improved operating results, though the company remains unprofitable.

What drove revenue growth for Phathom Pharmaceuticals (PHAT) in Q1 2026?

Revenue growth came from higher U.S. sales of VOQUEZNA products, which generated $58.3 million in net product revenue. The company saw growing prescription volume and prescriber adoption, with most prescriptions written for GERD indications following launches for erosive and non-erosive GERD and H. pylori treatment.

What is Phathom Pharmaceuticals’ (PHAT) cash position and debt load?

As of March 31, 2026, Phathom held $180.9 million in cash and cash equivalents. It also had $175.0 million of term loan principal outstanding and a $380.9 million revenue interest financing liability linked to future vonoprazan sales, resulting in significant ongoing interest expense obligations.

When does VOQUEZNA exclusivity expire for Phathom Pharmaceuticals (PHAT)?

All VOQUEZNA products benefit from New Chemical Entity exclusivity through May 3, 2032. The FDA granted qualified infectious disease product status for VOQUEZNA DUAL PAK and TRIPLE PAK, and later aligned VOQUEZNA tablets with the same ten-year exclusivity period for vonoprazan, helping protect U.S. market position.

How many VOQUEZNA prescriptions have been filled since launch for Phathom (PHAT)?

By April 17, 2026, approximately 1.35 million prescriptions for VOQUEZNA, VOQUEZNA DUAL PAK, and VOQUEZNA TRIPLE PAK had been filled in the U.S. This reflects broad commercial uptake, supported by coverage for over 120 million commercially insured lives and a focused gastroenterology sales effort.

What are the main obligations under Phathom’s revenue interest financing agreement?

Investors receive a royalty on vonoprazan net sales until they collect 200% of the total investment amount. The liability stood at $380.9 million at March 31, 2026. If minimum cumulative payment thresholds are not met by specified future dates, Phathom must make additional cash payments to reach those minimums.
