SAN FRANCISCO, CA / March 11, 2022 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar" or the "Company") today provided company updates and reported consolidated financial results for the year ended December 31, 2021.

"2021 was a year of transition and progress for Jaguar's plant-based drug pipeline for human health," said Lisa Conte, the Company's president and CEO, "as we continued enrollment in our OnTarget Phase 3 clinical trial of crofelemer for prophylaxis of cancer therapy-related diarrhea (CTD) and advanced this key pipeline initiative with the presentation at December's San Antonio Breast Cancer Symposium of Phase 2 crofelemer data for prophylaxis in chemotherapy-related diarrhea; received Orphan Drug Designation in the European Union for crofelemer for short bowel syndrome; formed Napo Therapeutics in Milan, Italy, which was subsequently funded as a result of the merger of Napo Therapeutics with Milan-based Dragon SPAC S.p.A. and for which Jaguar Health is the majority shareholder; and completed a license agreement with Napo Therapeutics for exclusive rights to crofelemer and lechlemer in Europe. In December we also excitingly and importantly received FDA conditional approval for Canalevia-CA1 (crofelemer) for treatment of chemotherapy-induced diarrhea (CID) in dogs."

2022 UPDATES, YEAR-TO-DATE ACCOMPLISHMENTS, AND MILESTONES:

"We look forward to 2022 being an exciting year with the continued development of crofelemer - our ‘pipeline within a product'; continuing efforts to forge license and business development relationships; our continuing Canalevia-CA1 launch and continued sales of Mytesi^®; and, most importantly, providing relief with a novel first-in-class mechanism of action to patients in need - including patients for whom no alternative therapeutic options exist," Conte said.

Core 2022 Initiatives & Milestones:

• Phase 3 clinical trial of crofelemer for cancer therapy-related diarrhea (CTD) in humans: The pivotal OnTarget Phase 3 clinical trial of crofelemer for prophylaxis of CTD was initiated in October 2020 and is ongoing. The Company is in the process of adding additional clinical trial sites - both in the US and outside the US - to accelerate patient enrollment. Further details about the trial can be viewed here on the clinicaltrials.gov website. A significant proportion of patients undergoing cancer therapy experience diarrhea, and diarrhea has the potential to cause dehydration, potential infections, and non-adherence to treatment in this population. Patients with CTD are 40% more likely to discontinue their chemotherapy or targeted therapy than patients without CTD.¹
• 2H 2022 Milestone: Initiation and completion of an investigator-initiated proof-of-concept study of crofelemer for short bowel syndrome with intestinal failure (SBS-IF): Napo Therapeutics is supporting this investigator-initiated study of crofelemer in patients with short bowel syndrome (SBS) or congenital diarrheal disorders (CDD) with intestinal failure, with a planned primary endpoint of reduction of weekly volume of parenteral nutrition. On December 13, 2021, the European Medicines Agency (EMA) granted orphan-drug designation (ODD) for crofelemer for SBS in the European Union, and crofelemer has received ODD in the US for SBS. The EMA is committed to enabling early patient access to new medicines, particularly those that target an unmet medical need, and ODD status in the EU is expected to support Napo Therapeutics' plans to make crofelemer available through Early Access Programs in the EU for SBS. Participation in Early Access Programs provides a potential opportunity for meaningful revenue generation in addition to the ability to impact important morbidity, mortality, and the cost of care for chronically ill patients for whom no therapeutic options exist. SBS affects approximately 10,000 to 20,000 people in the U.S.², according to the Crohn's & Colitis Foundation, and it is estimated that the population of SBS patients in Europe is approximately the same size.³ Despite limited treatment options, the global SBS market exceeded $568 million in 2019 and is expected to reach $4.6 billion by 2027, according to a report by Vision Research Reports.
• Mid-2022 Milestone: Filing of an Investigational New Drug (IND) application with the FDA for NP-300 (lechlemer) in support of the initiation of a Phase 1 lechlemer study in 2H 2022 for the symptomatic relief of diarrhea from cholera: Lechlemer is the company's drug product candidate for symptomatic relief of diarrhea from cholera. It is a standardized and proprietary botanical drug product that is sustainably derived from the same source as crofelemer - the Croton lechleri tree. In support of the planned IND application filing for lechlemer, the Company received comprehensive animal toxicity preclinical services supported by the National Institute of Allergy and Infectious Diseases for four preclinical studies. The Company intends to pursue a tropical disease priority review voucher under the FDA's financial incentive program to develop drugs for tropical diseases such as cholera.
• 2022: Jaguar's year of the dog: Launch activities remain underway for Canalevia-CA1 in the US veterinary market for the treatment of CID in dogs and included CID Treatment Forums on January 16^th and March 6^th for veterinarians, veterinary oncologists, and members of the media during the Veterinary Meeting & Expo (VMX) Conference in Orlando and the Western Veterinary Conference (WVC) in Las Vegas. Dogs, as with humans, must go off their disease modifying chemotherapy approximately 40% of the time due to diarrhea, and dogs are a predictive model of the human situation. As announced, Jaguar expects that Canalevia could additionally receive FDA conditional approval, under the name Canalevia^™-CA2, for the treatment of exercise-induced diarrhea (EID) in dogs in the fourth quarter of 2022.
• Investigator-initiated trials of crofelemer that are ongoing in 2022:
• Chronic idiopathic diarrhea in non-HIV adult patients
  • Study Name: Yield of Diagnostic Tests and Management of Crofelemer for Chronic Idiopathic Diarrhea in Non-HIV Patients: A Pilot Study
  • Location: University of Texas Health Science Center at Houston
• Functional diarrhea in non-HIV adult patients
  • Study Name: A randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and efficacy of crofelemer in subjects with functional diarrhea
  • Location: Beth Israel Deaconess Medical Center, a Harvard Medical School institution in Boston

"As of March 11, 2022, the filing date of Jaguar's annual report on Form 10-K for the year 2021, the Company's cash position was approximately $18.5 million, and the Company had a public float exceeding $75 million. Therefore, the Company remains ‘shelf eligible,'" said Conte. "There are benefits of having a shelf registration statement on Form S-3 in place, rather than a registration statement on S-1. At present, we have continuing flexibility to issue registered shares quickly and opportunistically, including in connection with potential future business transactions such as asset acquisitions, purchases of product, payments for services, and license deals, and we are pleased with the flexibility the ATM financing program provides."

COMPANY FINANCIAL RESULTS FOR THE YEAR ENDED DECEMBER 31, 2021:

"Fourth quarter 2021 Mytesi net revenue was approximately $2.1 million versus approximately $0.6 million in the third quarter of 2021. This increase of 230%, or $1.5 million, largely represents the important realization of the benefits - from both a financial perspective and the standpoint of improved patient access - from Jaguar's shift to distributing Mytesi through a closed network of specialty pharmacies," said Conte. "The process of transitioning to a closed network of specialty pharmacies resulted in a one-time, short-term underrepresentation of Mytesi utilization. As anticipated, Mytesi revenue, primarily in the third and fourth quarters of 2021, was impacted by this transition as wholesalers in the retail distribution channel drew down their inventory of typically more than two-month's volume. Our closed network of specialty pharmacies typically orders on a just-in-time inventory business model."

"I am pleased to report that the Company completed the process of transitioning its Mytesi volume to a closed network of specialty pharmacies (rather than to wholesalers that resell the product to retail pharmacies) this past January," said Ian Wendt, Jaguar's Chief Commercial Officer, "and that no significant Mytesi inventory is left in the retail distribution channel. Mytesi new prescription volume, the metric we believe to be the best indicator of growth in patient demand, increased 10.4% in the fourth quarter of 2021 over the third quarter of 2021, and increased by 2.1% in the year 2021 over the year 2020. The transition to a closed network of specialty pharmacies has resultedin a meaningful reduction in Mytesi distribution costs and a higher average net price and assists in the preparation of the Company's U.S. commercial distribution network for potential future indication expansion of crofelemer to other populations of patients with complex medical needs, such as CTD and SBS."

• Mytesi Prescription Volume: As stated above, Mytesi new prescription volume, the metric the Company believes to be the best indicator of growth in patient demand, increased 10.4% in the fourth quarter of 2021 over the third quarter of 2021, and increased 2.1% in the year 2021 over the year 2020. Prescription volume differs from invoiced sales volume, which reflects, among other factors, varying buying patterns among wholesalers in the retail channel and specialty pharmacies in the closed network as they manage their inventory levels.
• Mytesi Net Product Revenue: Mytesi net revenue during the fourth quarter of 2021 was approximately $2.1 million and approximately $0.6 million in the third quarter of 2021, an increase of $1.5 million, or 230%, quarter over quarter. The transition to a closed network of specialty pharmacies has resulted in a meaningful reduction in Mytesi distribution costs and a higher average net price. Mytesi net revenue for the year 2021 was approximately $4.3 million and approximately $9.4 million for the year 2020, a decrease of approximately $5.1 million year over year. As part of the process of transitioning to the closed specialty pharmacy network, the third and fourth quarters of 2021 were significantly impacted by the inventory draw-down of approximately 1,300 bottles of Mytesi across the Company's third-party logistics warehouse, wholesalers, distributors, and retail stores.
• Mytesi Gross Product Revenue (Non-GAAP): Mytesi gross revenue was approximately $3.0 million and $3.2 million during the fourth and third quarter of 2021, respectively, representing a decrease of $0.2 million quarter over quarter. Mytesi gross revenue for the year 2021 was approximately $15.7 million and approximately $20.4 million for the year 2020, a decrease of $4.7 million year over year. As described above, the third and fourth quarters of 2021 were significantly impacted by the inventory draw-down of approximately 1,300 bottles of Mytesi across the Company's third-party logistics warehouse, wholesalers, distributors, and retail stores; and the transition to distribution through the closed specialty pharmacy network improved the Mytesi net-to-gross revenue ratio.
• Mytesi Volume Through Specialty Pharmacies: Mytesi sales volume distributed through the recently established, and expanding, closed network of third-party specialty pharmacies was 100% of total sales in the fourth quarter of 2021 compared to approximately 38% in the third quarter of 2021. The Company believes the availability of Mytesi through specialty pharmacies represents a significant benefit to patients, as such pharmacies focus on complex and chronic conditions and offer a higher level of support for prior authorizations, appeals, adherence counseling, and home delivery options, and prepares the Company's U.S. distribution network for the anticipated future indication expansion of crofelemer to other populations of patients with complex medical needs.
• Neonorm^™: Neonorm non-prescription product revenues were minimal for the year 2021 and the year 2020, in accordance with the Company's primary focus on human health and prescription products.

• Cost of Product Revenue: Total cost of product revenue for the year 2021 was $2.3 million compared to $3.3 million for the year 2020, representing a $1.0 million decrease year over year. This decrease in cost of product revenue was largely due to the decrease in sales.
• Research and Development: The R&D expense was $15.1 million for the year 2021 compared to $6.4 million for the year 2020, an increase of $8.7 million year over year. Clinical and contract manufacturing expenses increased $4.6 million from $1.7 million for the year ended December 31, 2020, to $6.3 million in 2021 largely due to increased clinical trial activities related to the start-up of CTD and other indications, additional CMC manufacturing, expenses related to consulting and contractors, and cholera/lechlemer research expenses. In addition, personnel and related benefits increased $2.2 million from $1.8 million for the year 2020 to $4.0 million for the year 2021 due to compensation and additional headcount. Non-cash stock-based compensation expense increased $0.6 million from $0.7 million for the year 2020 to $1.3 million for the year 2021, primarily due to new options and restricted stock units granted in April 2021. Other expenses consisting of consulting, formulation, and regulatory fees increased $3.5 million for the year 2021 compared to $2.2 million for the year 2020, which is consistent with the increased activity in development of multiple potential follow-on indications for crofelemer.
• Sales and Marketing: The Sales and Marketing expense was $8.9 million for the year 2021 compared to $6.6 million for the year 2020, an increase of $2.3 million year over year. The increase in Sales and Marketing expense was largely due to an increase in marketing programs for Mytesi related to the expanding market access through specialty pharmacy channels.
• General and Administrative: The G&A expense was $17.1 million for the year 2021 compared to $14.4 million for the year 2020, an increase of $2.7 million year over year. The increase in G&A expenses was largely due to an increase of $1.5 million in personnel and related benefits due to increased resources, an increase in non-cash stock-based compensation of $0.5 million due to continued vesting of option grants, and an increase in public company expense of $1.1 million due to investor relations and expenses related to Jaguar's 2021 Annual Meeting of Shareholders. In addition, an increase of $0.3 million in audit, tax and accounting services was due to out-of-scope services, and an increase of $0.2 million in travel expenses due to loosening of Covid restrictions. These expenses were offset by decreases of $0.4 million in rent and lease as a result of the transfer to a lower-cost facility and the occupancy of less space, a decrease of $0.2 million in legal fees, and a decrease of $0.3 million in other expenditures largely due to decreased consulting expenses.
• Loss from Operations: For the year 2021, the loss from operations was $40.7 million compared to a loss of $26.6 million for the year 2020, an increase of $14.1 million year over year.
• Net Loss: For the year 2021, the net loss was $52.6 million, compared to a net loss of $38.6 million for the year 2020, an increase of $14.0 million year over year. In addition to the loss from operations:
  • Interest expense increased by $5.6 million from $2.8 million for the year 2020 to $8.4 million for the year 2021 primarily due to royalty interest agreements.
  • Change in fair value of financial instruments and hybrid instruments designated at fair value option ("FVO") losses decreased $0.8 million from a loss of $2.7 million for the year 2020 to $1.9 million for the year 2021 designated at FVO.
• Non-GAAP EBITDA: Non-GAAP EBITDA for the year 2021 and the year 2020 was a net loss of $37.5 million and $24.3 million, respectively.

Note Regarding Use of Non-GAAP Measures

The Company supplements its condensed consolidated financial statements presented on a GAAP basis by providing gross sales, non-GAAP EBITDA, and non-GAAP recurring EBITDA, which are considered non-GAAP under applicable SEC rules. Jaguar believes that the disclosure items of these non-GAAP measures provide investors with additional information that reflects the basis upon which Company management assesses and operates the business. These non-GAAP financial measures are not in accordance with GAAP and should not be viewed in isolation or as substitutes for GAAP net sales and GAAP net loss and are not substitutes for, or superior to, measures of financial performance in conformity with GAAP.

Gross sales percentages issued by the Company are based on gross sales figures that represent Mytesi orders placed by wholesalers with Jaguar's third-party logistics warehouse, less allowances for rebates, chargebacks, and discounts, which generate the cash flows for Napo Pharmaceuticals, Inc. ("Napo"), Jaguar's wholly owned subsidiary. Gross sales are used internally by management as an indicator of and to monitor operating performance, including sales performance of Mytesi, salesperson performance, and product growth or declines. The Company believes that the presentation of gross sales provides a closer to real-time useful measure of our operating performance. Gross sales are not a measure that is recognized under accounting principles generally accepted in the United States of America ("GAAP") and should not be considered as an alternative to net sales, which is determined in accordance with GAAP, and should not be used alone as an indicator of operating performance in place of net sales. Additionally, gross sales may not be comparable to similarly titled measures used by other companies, as gross sales have been defined by the Company's internal reporting practices. In addition, gross sales may not be realized in the form of cash receipts as promotional payments and allowances may be deducted from payments received from certain customers. Mytesi gross sales are reduced by Medicare, ADAP 340B chargebacks, returns, and wholesale distribution fees based on historical trends to determine net sales.

The Company defines non-GAAP EBITDA as net loss before interest expense and other expense, depreciation of property and equipment, amortization of intangible assets, share-based compensation expense and provision for or benefit from income taxes. The Company defines non-GAAP Recurring EBITDA as non-GAAP EBITDA adjusted for certain non-recurring revenues and expenses. Company management believes that non-GAAP EBITDA and non-GAAP Recurring EBITDA are meaningful indicators of Jaguar's performance and provide useful information to investors regarding the Company's results of operations and financial condition.

About Mytesi^®

Mytesi (crofelemer) is an antidiarrheal indicated for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy (ART). Mytesi is not indicated for the treatment of infectious diarrhea. Rule out infectious etiologies of diarrhea before starting Mytesi. If infectious etiologies are not considered, there is a risk that patients with infectious etiologies will not receive the appropriate therapy and their disease may worsen. In clinical studies, the most common adverse reactions occurring at a rate greater than placebo were upper respiratory tract infection (5.7%), bronchitis (3.9%), cough (3.5%), flatulence (3.1%), and increased bilirubin (3.1%).

See full Prescribing Information at Mytesi.com. Crofelemer, the active ingredient in Mytesi, is a botanical (plant-based) drug extracted and purified from the red bark sap of the medicinal Croton lechleri tree in the Amazon rainforest.
