Leiden, the Netherlands, March 13, 2025: Pharming Group N.V. (“Pharming” or “the Company”) (Euronext Amsterdam: PHARM / Nasdaq: PHAR) presents its preliminary (unaudited) financial report for the three months and full year ended December 31, 2024.

Chief Executive Officer, Fabrice Chouraqui commented: “I am delighted to have been appointed as CEO of Pharming and am deeply excited for the opportunities that lie ahead. The strength of the results presented today, with record RUCONEST® revenue and strong Joenja® growth, is testament to Pharming’s momentum.

We ended 2024 on a strong note, growing total revenues by 21% to US$297.2 million and exceeding our revenue guidance range of US$280-$295 million. This achievement underscores the continued importance of RUCONEST® in the HAE treatment landscape as well as the strong commercial performance of Joenja® in just its first full year of sales.

We enter 2025 with a number of regulatory reviews for leniolisib ongoing as we prepare for launches in key markets and for pediatrics. We also advanced our efforts to expand the addressable patient population for leniolisib, with two Phase II trials in additional PIDs now underway. The genetically identifiable PIDs indication and the CVID indication first announced today represent significantly larger market opportunities than APDS, with blockbuster revenue potential.

We are also strengthening our clinical pipeline with the acquisition of Abliva, which has now been completed. This adds a potential first-in-disease treatment for primary mitochondrial diseases, KL1333, which has the opportunity to further transform Pharming’s growth trajectory as it too has blockbuster potential. The acquisition aligns with our vision to become a leading global rare disease company and is well aligned with our operational capabilities. We are now moving to start the second wave of patient recruitment for the pivotal FALCON clinical trial as soon as possible.

Pharming’s 2024 financial performance was also noteworthy, with the company generating an operating profit and positive net cash flows from operations in the last two quarters of the year. This performance highlights the financial strength of our core commercial business.

Looking to 2025, we will continue to invest diligently to grow our portfolio in the U.S. and Joenja® in key countries, to reach more patients with APDS, and to progress the significant opportunities in our R&D pipeline for PIDs and primary mitochondrial diseases.

I firmly believe that Pharming is well-positioned to build on this positive momentum and embrace a new cycle of growth, delivering strong long-term value creation for all stakeholders and continuing our mission to serve the unserved rare disease patients. I look forward to working with the Pharming team to make this a reality.”

Fourth quarter and full year 2024 highlights

Commercialized productsRUCONEST® marketed for the treatment of acute HAE attacks

RUCONEST® demonstrated significant strength in the fourth quarter of 2024, with record revenues of US$79.6 million, a 9% increase compared to the fourth quarter of 2023. RUCONEST® revenues for the full year 2024 were a record US$252.2 million, an 11% increase compared to 2023, significantly above our expectation for mid single digit percentage growth.

The U.S. market contributed 98% of 2024 revenues, while the EU and Rest of World contributed 2%.

The strong RUCONEST® revenue growth in 2024 can be attributed to strong performance in new physicians prescribing RUCONEST®, new patient enrollments, and the total number of patients, which together resulted in over 6% unit sales growth vs. 2023. We achieved over 100 new patient enrollments in the fourth quarter and total enrollments in 2024 were up 24% vs. 2023. We also increased the RUCONEST® physician prescriber base by 11% during the year, in many cases adding previously unknown HAE prescribers.

Joenja® (leniolisib) marketed in the U.S. - the first and only approved disease modifying treatment for APDS

Joenja® revenues increased to US$13.1 million in the fourth quarter of 2024, a 66% increase compared to the fourth quarter of 2023. This increase was mostly driven by higher volume from the increase in patients on paid therapy in the U.S. compared to the fourth quarter of 2023, and a significant increase in revenues from EU and Rest of World which are from product provided on a named patient basis. Revenue for 2024, the first full year of sales following launch in April 2023, was US$45.0 million, compared to US$18.2 million in 2023.

The U.S. market contributed 90% of 2024 revenues, while the EU and Rest of World contributed 10%.

As of December 31, 2024, we had 96 patients on paid therapy in the U.S. and an additional five patients enrolled and pending authorization, representing an increase of active patients during the fourth quarter and continued progress enrolling and transitioning eligible patients to paid therapy.

APDS patient finding

As of December 31, 2024, Pharming had identified over 880 diagnosed APDS patients in global markets, including over 240 patients in the U.S. Of the identified patients in the U.S., over 150 patients are 12 years of age or older and eligible for treatment with Joenja®.

Pharming continues to advance several initiatives to diagnose additional APDS patients, including a sponsored genetic testing program in the U.S. and Canada, partnerships with several genetic testing companies who undertake their own testing efforts, and family testing programs.

APDS patient finding - VUS resolution

Pharming is aware of approximately 1,200 patients in the U.S. with a Variant of Uncertain Significance, or VUS, in the PIK3CD or PIK3R1 genes and is supporting validation studies with various laboratories to confirm which of these variants are pathogenic for APDS. Patients with disease-associated variants would receive a molecular diagnosis of APDS and, therefore, potentially be eligible for Joenja® treatment. Based on data from Pharming’s navigateAPDS sponsored genetic testing program, PIK3CD and PIK3R1 VUSs are found at four times the frequency of those mutations currently classified as pathogenic / likely pathogenic for APDS. Furthermore, a completed literature review and pilot study resulted in 20% of VUS patients being reclassified to APDS, suggesting that there could be a significant increase in the number of APDS patients in the US once those patients with a VUS are reclassified.

As previously communicated, Pharming is supporting independent research to evaluate large numbers of VUSs without the need for additional patient testing. VUS resolution via high throughput screening methods is an established approach that is accepted as strong functional evidence for variant classification by various expert organizations including the American College of Medical Genetics (ACMG) and ClinGen (a National Institutes of Health-funded resource). One in vitro high throughput screening study was completed in the fourth quarter of 2024, identifying many novel variants leading to PI3Kδ hyperactivity. Pharming is now supporting clinical genetics laboratories across the US to be able to use their independent variant interpretation to reclassify variants and thus issue amended genetic testing reports for any variants these laboratories deem to be disease-causing. We anticipate that these endeavors will lead to the identification of new patients with APDS.

Joenja® (leniolisib) developmentLeniolisib for APDS

During 2024, we received regulatory approvals for leniolisib for patients 12 years of age or older in the U.K. and Israel, and advanced additional regulatory filings, to bring leniolisib to APDS patients outside of the U.S. We also made strong progress in our clinical trials to support APDS marketing approval for leniolisib in Japan and pediatric label expansion.

In total, there are currently 188 patients in a leniolisib Expanded Access Program (compassionate use), an ongoing clinical study, or a named patient program.

Pediatric clinical development

On December 11, 2024, we announced positive top line results for the multinational Phase III clinical trial for children 4 to 11 years of age, which has been evaluating leniolisib tablets in 21 children with APDS. The data are consistent with the improvements seen in the previously reported randomized controlled trial in adolescent and adult APDS patients. Global regulatory filings are planned to begin with a U.S. submission in the second half of 2025.

Japan clinical trial

We completed an interim analysis, after 12-weeks of treatment, for the Phase III clinical trial in Japan evaluating leniolisib for the treatment of APDS in adult and pediatric patients 12 years of age and older. The study’s safety and efficacy findings were in line with data from the randomized controlled trial used to support approvals in adolescent and adult APDS patients in the U.S. and other countries, and support a regulatory filing with Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) which is planned for mid-2025. An approval decision would be expected in nine months based on priority review of the application due to orphan drug designation (ODD) by the Ministry of Health, Labour and Welfare of Japan (MHLW) for the treatment of APDS.

European Economic Area (EEA)

We are on track to complete the manufacturing activities requested by the European Medicines Agency’s (EMA) Committee for Human Medicinal Products (CHMP) in regard to the ongoing review of the Marketing Authorisation Application (MAA) for leniolisib for the treatment of adult and pediatric patients 12 years of age and older and submit a response prior to the January 2026 deadline.

United Kingdom

On September 25, 2024, the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) granted marketing authorization for Joenja® (leniolisib) for the treatment of APDS in adult and pediatric patients 12 years of age and older. Leniolisib is currently under evaluation by the National Institute for Health and Care Excellence (NICE) regarding reimbursement within the National Health Service (NHS) in England and Wales.

Additional markets

In Australia, we filed a regulatory submission for patients 12 years of age and older in the third quarter of 2023 and, after positive feedback from the Australian Advisory Committee on Medicines, expect a final decision by mid-March 2025.

We filed a regulatory submission in Canada for APDS patients 12 years of age and older in the third quarter of 2023. We have had ongoing interactions with Health Canada that recently granted an extension to February 2026 to respond to a request for additional CMC data, in line with the EMA extension. We plan to respond in early 2026 and expect a regulatory decision in 2026.

Leniolisib for additional primary immunodeficiencies (PIDs)

We made strong progress during 2024 on our leniolisib indication expansion efforts. We are developing leniolisib for additional primary immunodeficiencies, or PIDs, which affect significantly more patients than APDS. These include (i) genetically identifiable PIDs with immune dysregulation linked to altered PI3Kδ signaling and (ii) common variable immunodeficiency, or CVID, with immune dysregulation identified independently of genetics.

We started the Phase II clinical trial evaluating leniolisib for PIDs with immune dysregulation linked to altered PI3Kẟ signaling in October 2024, and started a Phase II clinical trial for CVID with immune dysregulation in February 2025.

Primary immunodeficiencies (PIDs) with immune dysregulation linked to altered PI3Kδ signaling

On October 10, 2024, Pharming announced the start of a Phase II, proof of concept, clinical trial evaluating leniolisib in PIDs with immune dysregulation linked to PI3Kẟ signaling in lymphocytes, with similar clinical phenotypes and unmet medical needs to APDS. The first patient was dosed in the study on October 29, 2024 and enrollment is progressing. The clinical trial includes PID patients with ALPS-FAS, CTLA4 haploinsufficiency, NFKB1 haploinsufficiency and PTEN deficiency, among others. Epidemiology suggests a prevalence of approximately seven and a half patients per million in this targeted PID population, compared to one to two patients per million for APDS.

The Phase II clinical trial is a single arm, open-label, dose range-finding study to be conducted in approximately 12 patients. The objectives for the trial are to assess safety and tolerability, pharmacokinetics, pharmacodynamics, and explore clinical efficacy of leniolisib in the targeted PID population.

In February 2025, the FDA granted Fast Track designation for leniolisib for the treatment of PIDs linked to PI3Kẟ signaling. Fast Track is an FDA process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need.

Common variable immunodeficiency (CVID) with immune dysregulation

CVID with immune dysregulation represents a much larger group of PID patients, which may be identified independently of genetics, and with a targeted population prevalence of approximately 39 patients per million. The majority of CVID patients with immune dysregulation exhibit a spectrum of noninfectious autoimmune and end-organ lympho-infiltrative disease manifestations with similarities to APDS.

We engaged with the FDA and EMA on the CVID indication, and received positive feedback regarding the large unmet medical need and the rationale for evaluating leniolisib in CVID patients with immune dysregulation. We have initiated a Phase II study for leniolisib in CVID patients with immune dysregulation, with the first patient expected to be dosed in late March 2025.

Acquisition of Abliva AB

In December 2024, we announced the proposed acquisition of Abliva AB, via a public cash offer to the shareholders to acquire all issued and outstanding shares of Abliva, for approximately US$66.1 million. Abliva’s lead product KL1333 is currently in a pivotal clinical trial in mitochondrial DNA-driven primary mitochondrial diseases and has the potential to significantly enhance our future growth trajectory. We announced that we did not require external funding to fund the acquisition and development costs for KL1333.

KL1333 for mitochondrial DNA-driven primary mitochondrial diseases

KL1333 is in a pivotal clinical study (FALCON) in adult patients with genetically confirmed primary mitochondrial disease (PMD) with mitochondrial DNA (mtDNA) mutations who experience consistent, debilitating fatigue and muscle weakness (myopathy), and reduced life expectancy. Over 30,000 patients diagnosed with mtDNA mitochondrial disease would be potentially addressable by KL1333 in the U.S., EU4 (France, Germany, Italy, Spain) and the UK, offering blockbuster potential for this product in the U.S. alone.

KL1333 has shown positive clinical effects in a proof-of-concept Phase 1b study, and a pre-planned interim analysis of the ongoing pivotal FALCON trial demonstrated promising differences over placebo in both alternate primary efficacy endpoints passing futility. KL1333 has received Fast Track designation in the U.S. and Orphan Drug Designation for the treatment of PMD in the U.S. and EU. We are now moving to start the second wave of patient recruitment for the pivotal FALCON clinical trial as soon as possible. We anticipate the trial to read-out in 2027 with potential FDA approval by end of 2028.

Organizational updates

Ms. Inés Bernal was appointed Chief People Officer, or CPO, as of December 1, 2024, to lead the development, execution and monitoring of Pharming's people and culture strategy.On October 24, 2024, we announced that Mr. Sijmen de Vries, Executive Director and Chief Executive Officer, had informed the Board of Directors that he would not be available for reappointment at our next AGM.

Subsequent events

On January 21, 2025, we announced that the Board of Directors had nominated biopharmaceutical leader Mr. Fabrice Chouraqui as Pharming’s new Chief Executive Officer and Executive Director, succeeding Mr. Sijmen de Vries.

Mr. Chouraqui was appointed for a term of four years at the Extraordinary General Meeting of Shareholders (EGM) that took place on March 4, 2025.

Upon the appointment of Mr. Chouraqui, Mr. Sijmen de Vries resigned from the Board of Directors. To ensure a smooth hand-over of tasks and responsibilities, Mr. de Vries will remain a strategic advisor to the new CEO until December 31, 2025.

On February 20, 2025, we announced ownership of shares and voting rights in Abliva AB exceeding 90% and thereby initiated the necessary activities to delist the Company from the Nasdaq Stockholm exchange. Following delisting, we expect to be able to start the second wave of patient recruitment for the ongoing pivotal FALCON clinical trial for KL1333 for the treatment of mtDNA-driven primary mitochondrial diseases. Pharming has initiated a compulsory acquisition procedure in respect of the remaining shares in Abliva under the Swedish Companies Act. On March 3, 2025, Nasdaq Stockholm approved Abliva’s application for delisting and the last day of trading will be March 17, 2025. With these events, the acquisition of Abliva is now completed.

The acquisition of Abliva will be accounted for as a business combination. Substantially all of the value of the acquisition is concentrated in a single asset, KL1333. Following delisting as expected in March 2025, the acquisition would be reflected in our financial statements beginning with the first quarter 2025. At this point we expect the US$66.1 million acquisition price to be allocated to the fair value of the acquired identifiable assets and liabilities, with any excess to be recorded as goodwill. We do not expect any P&L impact at the acquisition date, besides recognition of acquisition costs incurred in 2025.Financial Summary

Financial highlights

Fourth quarter 2024

Revenues in the fourth quarter of 2024 increased by 14% to US$92.7 million from US$81.2 million in the fourth quarter of 2023 (US$74.8 million in the third quarter of 2024). RUCONEST® revenues amounted to US$79.6 million, a 9% increase compared to the fourth quarter of 2023. A volume increase in the U.S., and a U.S. price increase in line with CPI, were the primary factors behind this increase in RUCONEST® revenues. Joenja® revenues amounted to US$13.1 million in the fourth quarter of 2024, a 66% increase compared to the fourth quarter of 2023. This increase was primarily driven by an increase in volume.

Gross profit increased by US$6.4 million or 9% to US$80.5 million (4Q 2023: US$74.1 million), mainly due to the increase in revenues. This was partially offset by increased cost of sales, in part due to a one-off inventory impairment due to a power outage during the production process (US$ 1.1 million).

The operating profit amounted to US$6.7 million compared to an operating profit of US$1.1 million in the fourth quarter of 2023. This increase was primarily due to the increase in gross profit mentioned above, offset by the increase in operating expenses from US$73.6 million in the fourth quarter of 2023 to US$73.9 million. Fourth quarter 2024 operating expenses increased by US$9.2 million from US$64.7 million in the third quarter of 2024. Part of this 2024 increase was caused by one-off expenses, totaling US$6.2 million, including the full impairment of US$5.1 million (4Q 2023: US$4.7 million) on the leased DSP facility at Pivot Park in Oss, the Netherlands. Also contributing to the fourth-quarter increase were legal and advisory fees associated with the acquisition of Abliva AB, totaling US$1.1 million for the fourth quarter of 2024.

The net finance result amounted to a gain of US$0.4 million compared to a loss of US$3.8 million in the fourth quarter of 2023. This was primarily driven by favorable EUR/USD exchange rate developments, resulting in a foreign currency gain of US$2.6 million compared to a loss of US$2.9 million in the fourth quarter of 2023. Interest expense increased by US$1.5 million in the fourth quarter of 2024 compared to the previous year, following the convertible bond issuance in the second quarter of 2024.

In the fourth quarter of 2024, a net profit of US$3.7 million was realized, in contrast to a net loss of US$3.1 million in the fourth quarter of 2023. This improvement was primarily driven by the rise in gross profit supported by favorable EUR/USD exchange rate developments, partially offset by the increase in operating expenses.

Cash and cash equivalents, including restricted cash and marketable securities, decreased from US$173.3 million at the end of third quarter of 2024 to US$169.4 million at the end of the fourth quarter of 2024. This decrease was primarily driven by EUR/USD exchange rate developments (vast majority of cash and marketable securities position is EUR denominated), offset by positive cash flows from operations of US$9.3 million (4Q 2023: US$11.6 million), which includes a deduction of US$1.7 million in paid taxes (4Q 2023: US$0.7 million).

Full year 2024

In 2024, Pharming revenues increased by 21% to US$297.2 million. However, the operating loss declined to a loss of US$8.6 million, compared to a loss of US$5.4 million in 2023. Similarly, the net loss declined to US$11.0 million, compared to a net loss of US$10.5 million in 2023.

This section will further elaborate on Pharming's financial performance in 2024.

Revenues and Gross Profit

Total revenues for 2024 grew by 21%, reaching US$297.2 million, compared to US$245.3 million in 2023. Total RUCONEST® revenues were 11% higher at US$252.2 million, compared to revenues of US$227.1 million for 2023. Joenja® revenues amounted to US$45.0 million in 2024, a 147% increase compared to 2023 (first sales commenced at the start of the second quarter of 2023). This increase was primarily driven by an increase in volume.

Cost of sales increased by 40% from US$25.2 million in 2023 to US$35.4 million in 2024. Cost of inventories recognized as expenses in 2024 amounted to US$25.6 million compared to US$21.4 million in 2023. In addition to the higher unit sales volume, the rise was primarily attributed to rising production costs for RUCONEST®. The remainder of the increase in cost of sales in 2024 mainly stem from one-off impairment charges on inventory of US$4.8 million (2023: US$1.7 million) and royalty payments to Novartis on Joenja® sales of US$4.9 million (2023: US$2.1 million).

Gross profit increased by US$41.7 million, or 19%, to US$261.8 million for the year 2024. The primary driver for this increase was higher sales volumes of RUCONEST® and Joenja®.

Other income

Other income decreased to US$2.2 million compared to US$23.3 million in 2023. Other income in 2023 was supported by the sale of the Rare Pediatric Disease Priority Review Voucher (PRV) to Novartis for a pre-agreed, one-time payment of US$21.3 million.

Operating Profit (loss) and Other Operating Costs

For 2024, the operating loss increased to a loss of US$8.6 million compared to a loss of US$5.4 million for the prior year. This change was mainly due to the decrease in other income and the expected increase in operating expenses from US$248.8 million in 2023 to US$272.6 million, offset by the above mentioned increase in gross profit in 2024. The increase in operating expenses in 2024 was primarily related to a combination of continuing investments in Joenja® in the U.S., launch preparation for leniolisib outside of the U.S., increasing R&D investments to expand the addressable patient population for leniolisib, and increased payroll expenses due to business growth. Operating expenses in 2024 include one-off expenses, totaling US$6.2 million, including expenses related to the full impairment of the DSP facility at Pivot Park in Oss, the Netherlands, amounting to US$5.1 million (2023: US$4.7 million). Also contributing to the increase were legal and advisory fees associated with the acquisition of Abliva AB, totaling US$1.1 million in the fourth quarter of 2024.

Operating Profit (loss) excluding one-time events

The 2023 operating expenses included milestone payments for Joenja® of US$10.5 million in the second quarter and other income included one-time proceeds from the PRV sale of US$21.3 million. When compared on a like-for-like basis, excluding these one-time events in 2023, the operating loss decreased from US$16.2 million in 2023 to US$8.6 million in the current year.

Finance income and expenses

The net finance result amounted to a gain of US$1.9 million compared to a loss of US$6.3 million in 2023. This was primarily driven by a fair value gain of US$7.0 million upon the reclassification of the convertible bond-related derivative to equity. This fair value gain was a result of the decrease in value of the option component classified as a derivative from issuance until the physical settlement date of the newly issued convertible bond. Further positive results stem from favorable EUR/USD exchange rate developments, which led to a foreign currency gain of US$2.0 million compared to a loss of US$3.0 million in 2023. In addition, interest income from investments in marketable securities, which commenced in the second quarter of 2023, increased by US$1.2 million. These positive results were partially offset by the negative fair value adjustments in the BioConnection preference share of US$2.1 million (2023: US$0.9 million negative), US$2.8 million higher interest expenses and fees of US$1.2 million related to the 2024 issued convertible bond.

Income tax credit (expense)Income tax credit (expense) shifted from a US$1.5 million credit for the year ending December 31, 2023, to a US$2.5 million expense for the year ending December 31, 2024. This tax expense mainly results from the profits of Pharming in the US being taxed against a US Federal and State combined tax rate of 27.96%, while the losses in the Netherlands only partly result in an offsetting tax credit, as the share-based compensation expenses and losses in associates are generally non-deductible based on Dutch tax law.Net loss for the year

The Company had a net loss of US$11.0 million in 2024, compared to a net loss of US$10.5 million in 2023. In addition to the support in other income from the PRV and the milestone payments for Joenja® in 2023, the change was mainly due to an increase in gross profit, favorable EUR/USD exchange rate developments and the fair value gain upon the reclassification of the convertible bond-related derivative to equity, offset by an increase in operating expenses, higher tax expenses and higher interest expenses and fees on the 2024 issued convertible bonds.

Intangible assets

In 2024, intangible assets decreased by US$10.2 million, from US$71.3 million in 2023 to US$61.0 million in 2024. This decrease primarily resulted from regular amortization (amounting to US$6.3 million) and negative foreign currency effects (equivalent to US$4.0 million).

The amortization relates to regular amortization of software, the RUCONEST® licenses (US and EU) and the Joenja® license. The RUCONEST® license has a remaining amortization period of 13 years for the US and 7 years for the EU. The Joenja® license has a remaining amortization period of 12 years.

Property, plant and equipment

The value of property, plant and equipment decreased from US$9.7 million in 2023 to US$7.8 million in 2024. This decline was primarily driven by regular depreciation (US$2.3 million) and negative foreign currency effects (US$0.5 million), partially offset by capital expenditures (US$0.8 million).

Right-of-use assets

The right-of-use assets decreased from US$23.8 million in 2023 to US$16.1 million in 2024. This decline was primarily driven by regular depreciation (amounting to US$3.9 million), negative foreign currency effects (equivalent to US$0.9 million) and the full impairment of the DSP facility at Pivot Park in Oss, the Netherlands (totaling US$5.1 million).

The decrease in the right-to-use assets is partially offset by additions of cars (US$2.4 million) and building remeasurements (US$0.3 million). The 2024 building remeasurements were related to adjustments in the existing right-of-use assets to account for inflation-related higher lease payments.

Investments

Investments decreased by US$6.2 million to US$4.2 million as of December 31, 2024. This decline was primarily driven by the disposal of the equity investment in Orchard of US$2.1 million (following take-over), Pharming’s share in the net loss of BioConnection of US$1.1 million and US$0.6 million impairment to equity value (accounted for using the equity method) and a fair value decrease of US$2.1 million in the preference share in BioConnection, carried at fair value through the statement of profit and loss (FVTPL).

Inventories

Inventories decreased from US$56.8 million as of December 31, 2023 to US$55.7 million as of December 31, 2024.

Cash and cash equivalents and marketable securities

Cash and cash equivalents alone decreased by US$6.8 million to US$54.9 million as of December 31, 2024. The cash and cash equivalents position is managed in combination with the marketable securities position.

The combined total of cash and cash equivalents, together with restricted cash and marketable securities decreased from US$215.0 million at year-end 2023 to US$169.4 million at year-end 2024. This decrease was primarily driven by paid taxes of US$15.6 million and the repurchase of the outstanding convertible bonds amounting to US$134.9 million, offset by net proceeds of US$104.5 million for newly issued convertible bonds. Following negative operating cash flow in the first half of 2024, the third and fourth quarter operating cash flows were positive, also when adjusted for share based compensation.

Shareholders’ equity

Shareholders’ equity increased by US$1.6 million from US$218.8 million for the year ended December 31, 2023 to US$220.4 million for the year ended December 31, 2024. This increase was primarily driven by transactions recognized directly in equity relating to share based compensation and exercised options (totaling US$13.9 million) and the recognition of the value conversion rights of US$12.2 million related to the issued convertible bond in 2024. These increases were offset by the net loss of US$12.5 million and the other comprehensive loss of US$11.9 million. The other comprehensive loss was primarily driven by currency translation differences.

Convertible bond

The convertible bond position has decreased by US$56.0 million to US$82.4 million at year-end 2024, moving from US$138.4 million as of December 31, 2023. This decrease was mainly driven by the repurchase of the outstanding convertible bonds amounting to US$134.9 million, offset by the initial recognition of the newly issued convertible bonds for US$81.8 million. The difference between the initial recognition of the newly issued convertible bonds and the respective net proceeds of US$104.5 million relates to the initial value of the conversion option component. Following a fair value gain of US$7.0 million until the physical settlement date, the value of the conversion option component was reclassified to equity. Subsequently, the value of this equity component is not remeasured and amounts to US$12.2 million, net of income tax effects, at December 31, 2024.

Lease liabilities

Lease liabilities decreased by US$3.2 million, moving from US$33.1 million as of December 31, 2023 to US$29.9 million as of December 31, 2024. This decrease was primarily driven by monthly or quarterly lease payments of US$5.1 million and for the most part offset by new leases (amounting to US$2.4 million).

Outlook/Summary

For 2025, the Company anticipates:

• Total revenues between US$315 million and US$335 million (6% to 13% growth), with quarterly fluctuations expected.
• Total operating expenses not to exceed the prior year pre-Abliva impact, and a preliminary estimate of US$30 million in Abliva-related operating expenses, including research and development and non-recurring transaction and integration expenses.
• Significant progress finding additional APDS patients in the U.S., supported by VUS validation efforts and subsequently converting patients to paid Joenja® (leniolisib) therapy.
• Increasing ex-U.S. revenues for leniolisib - driven by funded access programs and commercial availability in the U.K.
• Progress towards additional regulatory approvals for leniolisib for APDS patients 12 years of age or older, and submitting regulatory filings in Japan and for pediatric label expansion in key global markets.
• Advancing the two ongoing Phase II clinical trials in PIDs with immune dysregulation to significantly expand the long-term commercial potential of leniolisib.
• Advancing the ongoing pivotal FALCON clinical study for KL1333 in mitochondrial DNA-driven primary mitochondrial diseases.
• Continued focus on potential acquisitions and in-licensing of clinical stage opportunities in rare diseases. Financing, if required, would come via a combination of our strong balance sheet and access to capital markets.

No further specific financial guidance for 2025 is provided.
