United Therapeutics Corporation Acquires Thymmune TherapeuticsJuly 2, 2026 6:30 AM
Business Wire United Therapeutics Corporation (Nasdaq: UTHR) announced today it has acquired Thymmune Therapeutics, Inc. (Thymmune), a privately held, preclinical stage biotechnology company developing scalable, regenerative thymic cell therapies for the potential treatment of post-transplant organ tolerance, immunodeficiencies, and autoimmune diseases. The thymus is a critical organ for the development and proper function of key parts of the immune system, including training T-cells, which are essential for fighting infections and other diseases. Thymmune has a proprietary process for converting human-induced pluripotent stem cells (iPSC) into thymic cells, which — once inside the body — mature into cell types that can restore healthy T-cell function. Thymmune’s lead candidate, THY-100, is in preclinical development for congenital athymia, an ultra-rare and life-threatening condition in which infants are born without a functional thymus. Animal studies have shown that treatment with THY-100 results in the in vivo formation of a neo-thymus that is capable of facilitating T-cell development. The clinical proof of concept and further development of THY-100 has the potential to broaden thymic regenerative medicine approaches for transplant tolerance, serious immune-mediated diseases, and enhanced longevity for older adults with diminished T-cell function. “Thymmune’s platform complements United Therapeutics’ broader mission to expand the supply of transplantable organs, building on our UThymoKidney™ clinical development program and our growing strength in immunomodulatory therapeutics,” said Martine Rothblatt, Ph.D., Chairperson and Chief Executive Officer of United Therapeutics. “By restoring or modulating T-cell receptor diversity, Thymmune’s technology could make fundamental contributions to human health care and potentially resolve the root causes of dozens of life-threatening diseases.” “Thymmune was founded to harness the biology of the thymus to restore immune function for patients with serious immune-mediated diseases,” said Stan Wang, M.D., Ph.D., Chief Executive Officer and Founder of Thymmune Therapeutics. “United Therapeutics shares our conviction that regenerative medicine can transform the lives of patients, and we believe its leadership in organ alternatives and cell-based technologies makes it the ideal partner to advance our platform toward broad clinical impact.” Under the terms of the agreement, United Therapeutics acquired Thymmune for $140 million in cash, subject to certain post-closing adjustments, plus potential earn-out payments to former Thymmune equityholders of up to $160 million based upon the achievement of certain clinical and regulatory milestones by the end of 2031. About United Therapeutics Founded by CEO Martine Rothblatt to discover a cure for her daughter's life-threatening rare disease, pulmonary arterial hypertension, United Therapeutics transforms the treatment of rare diseases and pioneers alternatives to expand the supply of transplantable organs. From our innovative therapies to our groundbreaking manufactured organs, we are bold and unconventional. We move quickly from scientific theory to practical technologies that can save lives. As a public benefit corporation, even our legal structure reflects our commitments. We serve patients, act with integrity, create long-term shareholder value, and operate with sustainable practices that protect the future we are working to build.

United Therapeutics Corporation Announces FDA Approval of the LungFX™ Device for Centralized Ex Vivo Lung PerfusionJune 29, 2026 6:30 AM
Business Wire LungFX™ is the first device approved for centralized ex vivo lung perfusion for donor organs not otherwise used for transplant, an important step in advancing United Therapeutics’ platforms United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation, today announced that the U.S. Food and Drug Administration (FDA) has granted premarket approval (PMA) of the LungFXTM device (LungFX) for use in centralized ex vivo lung perfusion (EVLP), a procedure that enables donor lungs to be assessed outside the body after procurement and before transplantation. The PMA, submitted by United Therapeutics’ wholly owned subsidiary, Lung Bioengineering Inc., included comprehensive safety and effectiveness data supporting use of LungFX to perform EVLP in a centralized facility. LungFX is indicated for centralized, ex vivo (outside the body) evaluation of deceased-donor lungs (single and double) that cannot be placed for transplantation by an organ procurement organization (OPO) with any of the matched candidates if using direct-to-recipient procurement and preservation procedures. LungFX provides normothermic perfusion and ventilation of procured donor lungs initially stored with cold static preservation solution. LungFX is intended to allow for re-assessment, in a controlled environment, of the suitability of procured donor lungs for transplantation into male and female patients aged 18 years or older with end-stage lung disease awaiting first-time (double or single) lung transplantation. Lungs accepted for transplantation after LungFX require a second period of storage with cold static preservation solution, and cumulative preservation time of transplanted lungs is not intended to exceed 20 hours. To date, Lung Bioengineering has performed 1,100 EVLP procedures using other approved devices, with 600 lungs accepted for transplant. Lung Bioengineering expects to add LungFX to its available services in 2027. “Today’s approval is a big step forward in reducing the large number of donor lungs — over 80% — that are unfortunately left behind instead of being transplanted,” said Martine Rothblatt, Ph.D., Chairperson and Chief Executive Officer of United Therapeutics. “The FDA approval of our LungFX device also marks an important milestone on our path toward using advanced technologies to create an unlimited supply of transplantable organs.” “Too many donor lungs go unused today,” said Dr. Kenneth McCurry, M.D., Director of the Cleveland Clinic Enterprise Transplant Center and investigator in the LungFX pivotal trial. “EVLP with this device provides additional clinical data to transplant teams to help determine whether donated lungs that might otherwise go unused are suitable for transplant. Our work with Lung Bioengineering over the last ten years has significantly increased the number of patients we have been able to successfully transplant.” “LungFX is the first EVLP device approved specifically for use in a fit-for-purpose centralized facility, expanding access for transplant programs without requiring them to build EVLP capabilities within their own hospitals. It also strengthens United Therapeutics’ platform for advancing new technologies designed to enhance donor lung function,” said Brandi Zofkie, M.P.H., Associate Vice President of Lung Bioengineering. Lung Bioengineering Inc., a wholly owned subsidiary of United Therapeutics, is the global leader in centralized EVLP. The company owns and operates facilities in Silver Spring, Maryland, and Jacksonville, Florida, dedicated to performing centralized EVLP procedures designed to extend preservation and enable assessment of donor lungs that might otherwise be deemed unsuitable for transplant. IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS There are no known contraindications. WARNINGS AND PRECAUTIONS The LungFX device is not intended for the preservation of donor lungs that could be matched and successfully placed by an OPO without utilization of the device. In the CLES Pivotal Study, the observed 12-month survival rate among recipients of LungFX lungs did not meet the pre-specified performance goal (> 95% posterior probability of 1 year survival > 81.2%); rates of 12-month overall mortality and Clinical Events Committee (CEC)-adjudicated lung graft-related mortality were higher in EVLP subjects as compared to non-EVLP contemporaneous control subjects; and two-year survival within several pre-specified subgroups were clinically less favorable among EVLP donor lungs than among non-EVLP control donor lungs. Before deciding to proceed with LungFX organ preservation, a physician should fully consider the risks and benefits of this device and those of other organ preservation modalities. Transplant physicians are advised to carefully review the available clinical data in the LungFX device labeling when considering its use for any donor lungs and recipients. Only qualified Lung Bioengineering personnel can operate the LungFX device. Only trained physicians can evaluate lung suitability for transplantation after LungFX device evaluation. Safety and effectiveness of the LungFX device is derived principally from clinical data collected prospectively in the CLES Pivotal Study within 1 year after organ preservation and transplantation and from 2 years of observational, post-transplantation survival. Therefore, the impact of the LungFX device on clinical outcomes such as longer-term recipient survival and graft function (e.g., chronic lung allograft dysfunction (CLAD)) is uncertain. Other approved devices allow for pre-transplant assessment of procured donor lungs under conditions of ex vivo normothermic perfusion and ventilation, and there are various approaches available for isolated cold static storage preservation of procured donor lungs. Each alternative has its own advantages and disadvantages. A physician should fully discuss these alternatives with transplant candidates to identify the type of donor organ and preservation method that best meets patient expectations. Safety and effectiveness of the LungFX device have not been studied in: Patients: individuals under 18 years of age; patients listed for same-side lung re-transplantation, multiple-organ transplantation involving the lung and another organ, or live donor lobar lung transplantation; and patients with HIV infection or Burkholderia cenocepacia infection. Donors/donor lungs: donors or donor lungs with confirmed pneumonia, persistent purulent secretions identified by bronchoscopy before donor lung excision, confirmed evidence of aspiration, significant mechanical lung injury or trauma, HIV or active hepatitis C. A device malfunction or User error could lead to a potential loss of a donor lung. ADVERSE EVENTS Patients receiving a lung evaluated with LungFX may experience adverse events (AEs) including those experienced with any lung transplant. Below is a list of some of the AEs observed during clinical studies of the device. Death Primary graft dysfunction (PGD) Chronic lung allograft dysfunction (CLAD) Respiratory failure Lung transplant rejection Pulmonary embolism Pneumonia Bronchostenosis Hypoxia Dysphagia These AEs were also observed in transplant recipients whose lungs did not undergo evaluation with the LungFX device prior to transplantation. PRESCRIPTION INFORMATION Caution: Federal law (USA) restricts this device to sale by or on the order of a physician. Please see the LungFX Physician Labeling and Instructions for Use for further detailed information.

United Therapeutics Corporation Announces FDA Clearance to Proceed with UHeart Xenotransplantation Clinical TrialMay 15, 2026 6:00 PM
Business Wire First-ever human clinical trial of a xenoheart intended to support potential registration through the submission of a Biologics License Application to the U.S. FDA United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation, today announced that the U.S. Food and Drug Administration (FDA) has granted clearance under the company’s Investigational New Drug application to proceed with a clinical study of its investigational UHeart™ derived from a pig with 10 gene edits. The study, known as EXPRESS, will enroll an initial cohort of up to two participants. United Therapeutics will provide the FDA with safety and efficacy data from the first UHeart xenotransplant recipient in the study before enrolling a second participant. Following FDA review of available safety and efficacy data from the initial two transplants, the study may then be further expanded, with the intent to support a Biologics License Application (BLA) with the FDA. “Moving a porcine-derived heart into human clinical trials represents another defining advancement for the field of xenotransplantation,” said Kristina DeSmet, Ph.D., DABT, Senior Director, Product Development at United Therapeutics. “The heart is one of the most complex solid organs to transplant, and proceeding into the clinic reflects years of coordinated scientific progress. For United Therapeutics, this milestone represents our third clinical trial in xenotransplantation and underscores the breadth of our platform, spanning end-stage renal disease and now life-threatening heart disease. Together, these programs reinforce our commitment to expanding transplant options for patients who currently have no other alternatives.” Noah Byrd, Ph.D., RAC, Vice President, Global Regulatory Affairs at United Therapeutics, added: “Patients with end stage heart disease continue to face profound limitations in available treatment options. This FDA clearance to proceed with our EXPRESS clinical trial will allow us to begin evaluating an innovative therapeutic option designed to address this unmet need.” About EXPRESS Study Design The study will start at a single center enrolling up to two participants. If safety and efficacy data from these initial participants are supportive, United Therapeutics intends to expand the study to enroll participants at additional centers to support submission of a BLA. The study is designed as a phase 1/2/3 trial (sometimes referred to as a “phaseless” study) to evaluate safety and efficacy of the UHeart seamlessly without moving through separate phase 1, phase 2, and phase 3 studies that are typically associated with conventional drug approvals. Participants will receive a UHeart transplant followed by a 24-week post-transplant follow-up period, including the evaluation of all study endpoints and safety assessments. After the 24-week post-transplant follow-up period, participants who received a UHeart will continue to be followed for the rest of their lives, including for survival, UHeart survival, and screening for zoonotic infections. Safety and efficacy data will be reviewed frequently by an independent Data Monitoring Committee. After at least 12 weeks post-transplant of the first participant, United Therapeutics will provide data to FDA prior to initiating a second transplant. If safety and efficacy results from the first 2 participants are supportive, the study sample size will be increased to enable the study to support registration. Efficacy Endpoints Efficacy endpoints include participant survival rate, UHeart survival rate, UHeart function1, change in quality of life in participants2 at 24 weeks post-transplant, and participant exercise capacity3. Overall survival time of participants receiving a UHeart and overall survival time of the UHearts themselves are also efficacy endpoints. Safety Endpoints Safety endpoints include the incidence of adverse events and serious adverse events, all-cause mortality, and the incidence of arrythmias, thromboembolic and ischemic strokes, zoonotic infections, and opportunistic infections. Key Participation Criteria Key participation criteria include those ≥50 years of age, diagnosed with end-stage or advanced heart failure (HF) classified as American College of Cardiology/American Heart Association stage D and New York Heart Association Class IV, and no remaining therapeutic options. Participants will be screened using a crossmatch assay to assess expected immunological compatibility with the UHeart. Participants must not need multiple organ transplants; must not have had a prior solid organ transplant; must not have support with venoarterial ECMO; must not have severe medical co-morbidities, including but not limited to chronic liver disease, severe central vascular disease, severe neurologic diseases, and uncontrolled diabetes; and must not have a history of medical noncompliance that may preclude adherence to the demands and requirements of xenotransplantation. Full inclusion and exclusion criteria for this study will be provided in a future listing on the clinicaltrials.gov website. About Advanced Heart Failure According to the Journal of Cardiac Failure, in the United States nearly 6.7 million adults 20 years of age or older have HF, and in 2023, HF was responsible for 14.6% of all causes of death according to a CDC report4. In 2023, only a fraction of Americans with HF were considered candidates and waitlisted for a human heart transplant (0.12% or 8,000 Americans), and only approximately 4,000 heart transplants were performed5. About UHeart United Therapeutics’ xenoheart, known by the proposed trade name UHeart, is an investigational xenoheart from a pig with 10 gene edits. Six human genes are added to the pig genome to facilitate immunological acceptance and compatibility of the organ in the human recipient. Four porcine genes are inactivated or “knocked out” to reduce the risk of organ rejection and to moderate growth.

United Therapeutics Corporation Presents New Data Spanning Pulmonary Hypertension Treatment, Lung Donor Expansion, and Xenotransplantation at ISHLT 2026April 20, 2026 6:30 AM
Business Wire
An interim analysis of the PHINDER study identifies non-invasive measures that may facilitate earlier detection and management of pulmonary hypertension (PH) in patients with interstitial lung disease (ILD)


An interim analysis from the ARTISAN study indicates that early, high-dose treatment with treprostinil reduced afterload, improved right ventricular function, and reversed cardiac remodeling in pulmonary arterial hypertension (PAH)


Additional presentations include comparing real-world outcomes for patients with ILD with and without PH after lung transplantation and data from United Therapeutics’ ex vivo lung perfusion (EVLP) and xenotransplantation programs


United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation, today announced that 11 new data presentations across its commercial and development portfolio will be presented at the International Society for Heart and Lung Transplantation (ISHLT) 46th Annual Meeting and Scientific Sessions taking place April 22-25, 2026, in Toronto, Canada.


"The data from ARTISAN and PHINDER suggest that earlier detection and intervention are key to improving outcomes for patients with PH. Whether it is identifying PH sooner in patients with ILD or indicating that aggressive, early treatment with treprostinil can meaningfully reverse right heart remodeling in PAH, we believe these findings have the potential to reshape how these devastating diseases are managed,” said Andrew Nelsen, PharmD, Vice President, Global Medical Affairs at United Therapeutics. “Importantly, presentations highlighting innovations from our EVLP and xenotransplantation programs reflect the breadth of our scientific portfolio and our determination to address the shortage of transplantable organs.”

United Therapeutics shares jump after positive results from Tyvaso trialMarch 30, 2026 8:37 AM
IH Market News
Shares of United Therapeutics Corporation (NASDAQ:UTHR) climbed about 12% on Monday after the company reported that its pivotal TETON-1 study of Tyvaso successfully achieved its primary endpoint in patients with idiopathic pulmonary fibrosis (IPF).The inhaled therapy demonstrated clear superiority over placebo in improving absolute forced vital capacity, showing a treatment difference of 130.1 mL. The drug also reduced the risk of clinical worsening in patients with IPF, with results surpassing those observed in the earlier TETON-2 trial.Tyvaso also reached statistical significance in lowering the likelihood of clinical deterioration and delivered numerical improvements across several secondary measures compared with placebo. These included time to first acute IPF exacerbation, percent predicted FVC, K-BILD quality-of-life scores, and DLCO measurements.Combined analysis of data from both the TETON-1 and TETON-2 trials showed a statistically significant benefit versus placebo for the primary endpoint, with an improvement of 111.8 mL in absolute FVC from baseline to week 52. Positive effects were observed across all patient subgroups, including individuals receiving background therapies such as nintedanib or pirfenidone.The nebulized formulation of Tyvaso was generally well tolerated, and its safety profile aligned with previous studies of the drug. Researchers reported no new safety concerns.United Therapeutics said it intends to request priority review from the U.S. Food and Drug Administration for a supplemental New Drug Application expected to be submitted by the end of the summer, seeking approval to include IPF among the labeled indications for nebulized Tyvaso. Both the FDA and the European Medicines Agency have already granted orphan drug designation to treprostinil for the treatment of IPF.Further findings from the TETON-1 study, along with results from the combined analysis of both trials, are scheduled to be presented at the American Thoracic Society Annual Meeting in Orlando in May 2026.United Therapeutics Corporation stock price

United Therapeutics Corporation Announces Full Results of TETON-2 Phase 3 Clinical Trial Published in The New England Journal of MedicineMarch 11, 2026 6:14 PM
Business Wire
The pivotal study of Tyvaso® (treprostinil) Inhalation Solution demonstrated a statistically significant preservation of lung function across all subgroups, as measured by absolute forced vital capacity (FVC), and fewer clinical worsening events, compared with placebo over 52 weeks in patients with idiopathic pulmonary fibrosis (IPF)


Study authors noted TETON-2 is the first study to show that an inhaled therapy slowed progression of fibrosis as assessed by FVC change in patients with IPF


The trial population reflected the characteristics of a general population of IPF patients, with 75% on background antifibrotic therapy, demonstrating nebulized Tyvaso’s differentiated anti-fibrotic properties


If approved, nebulized Tyvaso will be the first and only inhaled anti-fibrotic treatment for IPF


United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation, today announced that the New England Journal of Medicine has published full results of its phase 3 TETON-2 study evaluating the use of nebulized Tyvaso for the treatment of IPF. The publication is available online at NEJM.org.


The study met its primary efficacy endpoint, with nebulized Tyvaso demonstrating statistically significant improvement in absolute FVC relative to placebo from baseline to week 52 in an IPF population broadly treated with background therapy. The median change in FVC at week 52 was -49.9 mL (95% confidence interval [CI], -79.2 to -19.5) in the nebulized Tyvaso group and -136.4 mL (95% CI, -172.5 to -104.0) in the placebo group, and the between group difference was 95.6 mL (95% CI, 52.2 to 139.0; P

Fourth Quarter 2025 Compared to Fourth Quarter 2024. Total Tyvaso revenues grew by 12 percent to $464.3 million in the fourth quarter of 2025, compared to $415.9 million in the fourth quarter of 2024. The growth in Tyvaso DPI revenues resulted primarily from an increase in quantities sold of $63.5 million, primarily due to continued growth in the number of patients following the product’s launch and, to a lesser extent, increased commercial utilization following implementation of the Medicare Part D benefit redesign under the Inflation Reduction Act (IRA). The decrease in Nebulized Tyvaso revenues resulted primarily from a decrease in quantities sold. The growth in Orenitram revenues resulted primarily from an increase in quantities sold of $10.3 million, driven, at least in part, by increased commercial utilization following the implementation of the Medicare Part D benefit redesign under the IRA.


Full Year 2025 Compared to Full Year 2024. Total Tyvaso revenues grew by 16 percent to $1,878.2 million in 2025, compared to $1,620.4 million in 2024, driven by growth in Tyvaso DPI revenues. The growth in Tyvaso DPI revenues resulted from an increase in quantities sold of $268.5 million, primarily due to continued growth in the number of patients following the product’s launch and, to a lesser extent, increased commercial utilization following implementation of the Medicare Part D benefit redesign under the IRA. The growth in Orenitram revenues resulted primarily from an increase in quantities sold of $46.0 million, driven, at least in part, by increased commercial utilization following the implementation of the Medicare Part D benefit redesign under the IRA.

Cost of sales, excluding share-based compensation.

See Share-based compensation section below for discussion.








(4)






Other primarily includes upfront fees and milestone payments to third parties under license agreements related to development-stage products, adjustments to the fair value of our contingent consideration obligations, and costs to acquire certain in-process research and development assets. During the year ended December 31, 2025, we recorded (a) $42.2 million in expense related to milestone payments for drug delivery device and formulation technologies; and (b) $10.8 million in expense related to adjustments to the fair value of contingent consideration obligations for manufactured organ and organ alternative projects. During the year ended December 31, 2024, we recorded $40.2 million and $8.0 million in expense related to upfront non-refundable licensing payments for drug delivery device technologies and ex vivo lung perfusion technology, respectively.







Research and development, excluding share-based compensation. The increase in research and development expense for the year ended December 31, 2025, as compared to the same period in 2024, was primarily due to: (1) increased expenditures related to manufactured organ and organ alternative projects; and (2) increased expenditures for drug delivery device and formulation technologies.

Calculation is not meaningful.







General and administrative, excluding impairment of PP&E, litigation accrual, and share-based compensation. The increase in general and administrative expense for the quarter ended December 31, 2025, as compared to the same period in 2024, was primarily due to increases in: (1) personnel expense due to growth in headcount; and (2) consulting expenses. The increase in general and administrative expense for the year ended December 31, 2025, as compared to the same period in 2024, was primarily due to increases in: (1) personnel expense due to growth in headcount; and (2) legal expenses related to litigation matters.


Impairment of PP&E. During the second quarter of 2025, we recorded a $21.7 million impairment charge to write down the carrying value of certain PP&E.


Litigation accrual. During the years ended December 31, 2025 and 2024, we recorded accruals of $3.0 million and $71.1 million, respectively, related to ongoing litigation with Sandoz Inc. We currently do not expect that the amount of any loss in excess of this accrual would be material to our financial results; however, the amount ultimately payable, if any, could be higher or lower than this amount depending on the amount of post judgment interest and the outcome of appeals, as discussed in Note 14—Litigation, to our consolidated financial statements included within our Annual Report on Form 10-K for the year ended December 31, 2025. The litigation accrual is included within selling, general, and administrative in our consolidated statements of operations.


Sales and marketing, excluding share-based compensation. The increase in sales and marketing expense for the year ended December 31, 2025, as compared to the same period in 2024, was primarily due to increases in: (1) personnel expense due to growth in headcount; and (2) marketing expenses.

The increase in share-based compensation expense for the quarter and year ended December 31, 2025, as compared to the same periods in 2024, was primarily due to: (1) an increase in restricted stock unit expense due to a greater number of outstanding performance-based restricted stock units during the quarter and year ended December 31, 2025, as compared to the same periods in 2024; and (2) an increase in stock option expense due to a greater number of unvested and outstanding performance-based stock options during the quarter and year ended December 31, 2025, as compared to the same periods in 2024, partially offset by a decrease in STAP expense, as all remaining STAP awards were exercised during the first quarter of 2025.


Other income (expense), net. The changes in other income (expense), net for the quarter and year ended December 31, 2025, as compared to the same periods in 2024, were primarily due to net unrealized gains on equity securities.


Income tax expense. Income tax expense was $379.2 million for the year ended December 31, 2025, as compared to $343.9 million for the same period in 2024. Our effective income tax rate was approximately 22 percent for the years ended December 31, 2025 and 2024.


Share repurchases. We entered into accelerated share repurchase agreements (ASR agreements) with Citibank, N.A. to repurchase approximately $1.0 billion of our common stock in each August 2025 and March 2024 ($2.0 billion in the aggregate). During the quarter and year ended December 31, 2025, we received 3,882 shares and 2,642,498 shares of our common stock, respectively, under these ASR agreements. During the quarter and year ended December 31, 2024, we received zero and 3,547,374 shares of our common stock, respectively, under these ASR agreements.

Statements included in this press release that are not historical in nature are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, among others, statements related to our anticipated readouts of our ADVANCE OUTCOMES and TETON-1 clinical trials and their impacts, including the possibility that they may result in significant new treatment options for patients or a period of transformational growth for our company; our expectation that we will continue delivering double-digit revenue growth; and our goals of expanding the supply of transplantable organs, developing practical technologies that can save lives, creating long-term shareholder value, and operating with sustainable practices. These forward-looking statements are subject to certain risks and uncertainties, such as those described in our periodic reports filed with the Securities and Exchange Commission, that could cause actual results to differ materially from anticipated results.
