•2Q 2023 revenues increased 9% to US$54.9 million, compared to 2Q 2022, driven by strong RUCONEST® revenues and the U.S. commercial launch of Joenja®

•RUCONEST® revenues increased 20% in 2Q 2023 to US$51.1 million, compared to 1Q 2023, but decreased 3% in 1H 2023 compared to 1H 2022

•Overall cash and cash equivalents, including restricted cash, of US$194.1 million at the end of 2Q 2023, compared to US$186.2 million at end of 1Q 2023

•Strong progress in efforts to make leniolisib available to APDS patients in key markets globally - CHMP opinion expected 4Q 2023, regulatory submissions filed in Canada, Australia, and Israel, and named patient program launched

Leiden, The Netherlands, August 3, 2023: Pharming Group N.V. (“Pharming” or “the Company”) (Euronext Amsterdam: PHARM/Nasdaq: PHAR) presents its preliminary (unaudited) financial report for the second quarter and first half ended June 30, 2023.

Chief Executive Officer, Sijmen de Vries, commented:

“The second quarter of 2023 was strong for Pharming. After the reimbursement disruptions experienced in the HAE market in the first quarter, RUCONEST® recovered significantly in the second quarter increasing 20% over the first quarter of 2023. Our RUCONEST® business performed well across a variety of leading revenue indicators, positioning us well for the second half of the year. RUCONEST® continues to provide a stable base for Pharming’s future growth, and we continue to foresee low single digit growth in sales for the year.

The Joenja® (leniolisib) U.S. launch got off to a strong start with the first reimbursed shipments to patients taking place in April; within two weeks of FDA approval. Our focus throughout the second quarter was enrolling identified U.S.-based APDS patients on Joenja® and working with payors on reimbursement. As of June 30, we have 60 patient enrollments and 43 patients on paid therapy, and US$3.8 million in associated revenues for the second quarter.

We continue to make good progress in identifying additional patients with APDS in key global markets. We have now identified over 640 patients in markets including the U.S., Europe, the U.K., Japan, Canada, Australia and Israel.

Through our regulatory, clinical, patient finding, and genetic testing efforts, we continue to make significant progress towards our goal of bringing this disease modifying treatment to adult and pediatric APDS patients worldwide.

Pharming’s progress continues to aid our patients and stakeholders as we focus on, and invest in, the long term growth of the company. I am immensely proud of our teams' many achievements in the first half of 2023.”

Second quarter and first half highlights

Commercialized assets

RUCONEST® marketed for the treatment of acute HAE attacks

Our RUCONEST® business had a strong second quarter, performing well across leading revenue indicators including active patients, vials shipped, and number of physicians prescribing. These positive indicators should position us well for the second half of the year.

Moreover, the underlying in-market demand for RUCONEST® in the U.S. continues to be strong. We received over 70 new patient enrollments in each quarter of 2023 underpinning the importance of RUCONEST® to HAE patients, including those patients on prophylaxis who should have medication on hand to treat any breakthrough attacks.

In the second quarter of 2023, RUCONEST® revenues were US$51.1 million, a 20% increase compared to the first quarter of 2023 and a 2% increase compared to the second quarter of 2022. For the first half of the year, RUCONEST® revenues were US$93.6 million, a 3% decrease compared to the first half of 2022. This was however a significant improvement when compared to the 9% revenue decrease experienced in the first quarter of 2023. The disruptions experienced in the first quarter, particularly in the month of February, impacted the entire U.S. HAE market across acute and prophylactic products and were temporary - as anticipated - and accounted for lower revenues in the first half of 2023 when compared to 2022.

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

On March 24, the U.S. FDA approved Joenja® (leniolisib) for the treatment of activated phosphoinositide 3-kinase delta (PI3Kδ) syndrome (APDS) in patients 12 years of age and older. Joenja®, an oral, selective PI3Kδ inhibitor, is the first and only disease modifying treatment approved in the U.S. for APDS.

The U.S. commercial launch of Joenja® is off to a strong start. First reimbursed shipments to patients took place in April; within two weeks of FDA approval. As of June 30, we received enrollments of 60 APDS patients of which 43 patients are already on paid therapy. Of the 43 patients on paid therapy, 19 were previously on therapy under our Expanded Access Program (EAP) or Open Label Extension trial (OLE). The remaining 24 patients were previously untreated patients or naïve. We anticipate nearly all future patients to be naïve to Joenja®.

Access and reimbursement discussions have been proceeding as expected. Given the rarity of APDS, the limited number of treatment options available, and that Joenja® is a disease modifying treatment and the only treatment indicated for APDS, we have seen high approval rates and fast timelines to covered therapy. Pharming’s market access teams are continuing to work with government and private payors to both educate and provide the resources needed to formulate their policies to ensure access and reimbursement.

Patient finding

Based on available literature, Pharming estimates that over 1,500 patients are affected by APDS in our key global markets including the U.S., Europe, U.K., Japan, Canada, Australia and Israel. Our patient finding efforts continue to progress, and as of June 30, Pharming has identified over 640 patients - versus the over 500 patients reported as of December 2022. Of these 640 patients, approximately 200 are U.S.-based with approximately 75% over the age of 12 and are therefore currently eligible for treatment with Joenja®.

During the second quarter, our primary focus during was enrolling patients previously identified with APDS in the U.S. and moving them onto paid therapy. As we enter the third quarter of 2023, we will intensify our focus towards conducting genetic testing, including testing family members of diagnosed patients, to identify additional individuals with APDS who may be eligible for treatment with Joenja®.

Milestone and royalty payments

As announced in April 2023, the first commercial sale of Joenja® triggered a US$10 million milestone payment by Pharming to Novartis. The regulatory approval for APDS also triggered a US$0.5 million milestone payment by Pharming to another party in the first quarter of 2023.

With the approval of Joenja®, and pursuant to the terms of Pharming’s 2019 exclusive license agreement with Novartis for leniolisib, Pharming is obligated to make certain one-off milestone payments to Novartis totaling up to US$200 million upon the first achievement of certain leniolisib sales levels in a calendar year and tiered royalty payments to Novartis calculated as low-teens, mid-teens to high-teens percentages of leniolisib net sales.

Sale of Priority Review Voucher

In June 2023, Pharming announced that it had entered into a definitive agreement to sell its Rare Pediatric Disease Priority Review Voucher (PRV) to Novartis for a pre-agreed, one-time payment of US$21.1 million. Pharming was granted the PRV by the Food and Drug Administration (FDA) in March 2023 in connection with the approval of Joenja®. The sale price was a pre-agreed, contractually defined percentage of the PRV value pursuant to the terms of the August 2019 exclusive license agreement between Pharming and Novartis for leniolisib.

Additional information on the PRV, milestones, and royalties can be found in our Annual Report 2022 or in the 2022 Annual Report on Form 20-F filed with the SEC on April 5, 2023.

Joenja® (leniolisib) strategic highlights - regulatory and clinical updates

Leniolisib for APDS

Pharming made significant progress over the first half of 2023 towards our objective of obtaining leniolisib regulatory approvals for APDS patients 12 years of age and older and for pediatric patients in key global markets. Furthermore, we continued to make progress in identifying additional indications for development of leniolisib beyond APDS.

EEA and U.K. market

In February, Pharming announced that the European Medicines Agency’s (EMA) Committee for Human Medicinal Products (CHMP) decided to shift its assessment of the Marketing Authorisation Application (MAA) for leniolisib for patients 12 years of age and older to a standard review timetable. The list of questions received by Pharming included a request to submit updated data from the ongoing long-term extension study collected after the interim analysis included in the original MAA.

In May, Pharming submitted its response to the CHMP Day 120 list of questions. Subsequently, as part of the MAA review procedure timetable, Pharming received the CHMP’s Day 180 list of outstanding issues in July. Considering the rarity of the disease and the unmet need for the treatment of APDS patients, the CHMP will consult an Ad-hoc Expert Group (AEG) at a closed meeting also involving Pharming representatives including leniolisib investigators and APDS patients. Under EMA regulations, the CHMP may call an AEG meeting when a medicine is being assessed that requires input from specialized scientific advisors on matters that may fall outside the expertise of the EMA’s established Scientific Advisory Groups, as is typically the case for rare diseases with few experts.

Pharming anticipates that the CHMP will issue its opinion on the leniolisib MAA in the fourth quarter of 2023, with European marketing authorisation following approximately two months later.

In the U.K., we intend to file the leniolisib dossier with the U.K.’s Medicines and Healthcare products Regulatory Agency (MHRA) within five days of a positive CHMP opinion, which is in line with the European Commission Decision Reliance Procedure (ECDRP).

Japan

In March, Pharming filed an Orphan Drug Designation (ODD) with the Ministry of Health, Labor and Welfare (MHLW) in Japan and in May we received confirmation that the ODD application had been accepted and granted by the MHLW.

Pharming’s planned 12-week clinical trial in Japan for patients 12 years of age and older was opened for enrollment in the second quarter. This single-arm, open-label trial will evaluate the safety, tolerability, and efficacy of leniolisib in three patients who have a confirmed APDS diagnosis. We expect the first patient to be enrolled in the third quarter.

Pharming plans to file an application for the approval of leniolisib with Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) following completion of the trial. Concurrent with the agency’s review, eligible patients enrolled in the trial will continue to receive the investigational drug for at least one year through an open-label extension trial.

Additional markets - Canada, Australia and Israel

In July, Pharming filed a New Drug Submission to Health Canada under priority review, which was granted in June 2023 for leniolisib for the treatment of APDS in patients 12 years of age and older.

In Australia, the Therapeutic Goods Administration (TGA) granted ODD for leniolisib for the treatment of APDS and priority review for Pharming’s planned regulatory submission. In July, Pharming filed its regulatory submission for leniolisib for the treatment of APDS in patients 12 years of age and older.

Both the Canadian and Australian regulatory filings are expected to be validated in the third quarter of 2023 with potential regulatory approvals by the second quarter of 2024.

---

Furthermore, Pharming confirms that the Product Registration Application for leniolisib for the treatment of APDS in patients 12 years of age and older was submitted to Israeli’s Ministry of Health in June. The Company expects to receive a decision from the Israeli Ministry of Health in the first half of 2024.

Named Patient Program

In June 2023, Pharming entered into a partnership with WEP Clinical LTD, a specialist services company that works with drug developers to help patients and physicians gain early access to medicines when no other treatment options are available, to launch a post approval named patient program for leniolisib. The program is designed to ensure that physicians in Europe and the rest of the world can request leniolisib on behalf of individual patients living with APDS in certain countries where leniolisib is not commercially available.

Pediatric clinical trials

In February 2023, Pharming confirmed that the first patient had been enrolled in its Phase III pediatric clinical trial with leniolisib for the treatment of APDS in patients 4 to 11 years of age. The single-arm, open-label, multinational clinical trial will evaluate the safety, tolerability, and efficacy of leniolisib in approximately 15 children at sites in the United States, Europe, and Japan.

The second pediatric clinical trial for patients 1 to 6 years of age is scheduled to commence in the third quarter of 2023.

Both studies are being conducted as part of Pharming’s Pediatric Investigational Plan (PIP) for leniolisib as a treatment for APDS in children.

Leniolisib for additional indications (PI3Kδ platform)

As announced in our Joenja® approval conference call on March 27, we have begun working towards prioritizing other indications where leniolisib has the potential to deliver value for patients. PI3Kδ has been identified as an important factor in a variety of disease states, and leniolisib has demonstrated an attractive, long-term efficacy, safety and tolerability profile in clinical trials conducted in both healthy volunteers and patients. This provides a basis for the investigation and investment in plans for further leniolisib indications.

We have already advanced plans for the second indication for leniolisib development, initiating discussions with the FDA on a clinical trial plan. We expect to provide details on this later this year.

Pre-Clinical Pipeline

OTL-105

Work is continuing on the preclinical proof of concept studies. We anticipate providing further updates as OTL-105 progresses towards an Investigational New Drug (IND) filing.

Financial highlights

1H 2023

Total revenues increased 1% during the first half of 2023 to US$97.4 million, versus US$96.8 million during the first half of 2022. For the first half of 2023, total RUCONEST® revenues were 3% lower at US$93.6 million, versus revenues of US$96.8 million for the first half of 2022.

Gross profit for the first half of 2023 remained stable at US$87.6 million compared to US$87.9 million for the first half of 2022.

Further details on revenue and gross profit segmentation is provided in Note 7 - Segment Information - in the Notes to the condensed consolidated interim financial statements of this press release.

Other income increased significantly in the first half of 2023 to US$22.5 million which was mainly due to the sale of the PRV to Novartis for US$21.1 million. This is in comparison to last year’s US$15.0 million which was primarily driven by a one-off gain due to the reduction in Pharming’s minority stake in BioConnection.

Operating loss for the first half of 2023 amounted to US$8.4 million. This was mainly due to US$36.3 million increase in operating cost when compared with the first half of 2022. Of that, US$10.5 million is related to milestone payments for Joenja®. A further US$7.3 million expense increase is directly related

9

---

to leniolisib in the form of increased R&D spent, marketing cost, market access costs and the commencement of the amortization of acquired rights. An increase of US$16.3 million is related to an increase in payroll and general expense, which was in large part driven by the expansion of the organization as a result of the launch and further commercialization of leniolisib but is also in part driven by cost inflation. The remainder of the increase is due to the increased IT cost (US$1.3 million) and due to incidental cost relating to the discontinuation of the Pompe disease program (US$0.8 million).

Net profit (loss) for the first half of 2023 was US$(10.9) million, versus US$19.2 million for the first half of 2022. This was due to a negative operating profit as Pharming continues to invest in the successful launch and commercialization of leniolisib in key global markets, as well as negative impact of net finance gains and losses, which were mainly due to less favorable EUR/USD exchange rate developments. This was partly offset by an income tax credit, whereas in the same period last year an income tax expense was recorded.

Cash and cash equivalents, together with restricted cash, decreased from US$208.7 million at the end of 2022 to US$194.1 million at the end of the second quarter of 2023. This was mainly due to the negative operating cash flows for 2023 (US$32.4 million), negative cash flows due to financing activities (US$5.3 million), offset by the positive cash flow in investing activities (US$20.1 million) which was driven by the sale of the PRV.

2Q 2023

For the second quarter of 2023, revenues increased by 9% to US$54.9 million, compared to US$50.1 million in the second quarter of 2022. This increase was driven by strong RUCONEST® sales recovery in the second quarter at US$51.1 million, a 20% increase compared with the first quarter of this year at US$42.5 million. U.S. Joenja® revenues accounted for 4% of total Group revenues during its first in-market quarter at US$3.8 million.

Gross profit increased by 7%, to US$49.2 million as compared to the same period last year.

Operating profit was down in the second quarter of 2023 at US$5.3 million versus US$17.8 million for the same period last year. This was a result of increased other operating costs of US$65.8 million in the second quarter of 2023 versus US$42.4 million in the second quarter of 2022. The increase in other operating costs included milestone payments of US$10.0 million following the first commercial sale of Joenja® in the U.S., which were included in marketing and sales costs. This was offset by the US$21.1 million of proceeds from the sale of the PRV to Novartis, which is reflected in other income. Last year’s results were supported by the one-off recognition of a gain of US$12.8 million in relation to the reduction of Pharming’s minority stake in BioConnection in the second quarter of 2022, also reflected in other income.

Net profit for the second quarter was US$1.3 million compared to US$15.7 million in the second quarter of 2022. This was mainly due to a decrease of US$12.5 million in the operating profit as Pharming continues to invest in the successful launch and commercialization of leniolisib in key global markets, as well as negative impact of net finance gains and losses, which were mainly due to less favorable EUR/USD exchange rate developments. This was partly offset by a decrease in income tax expenses.

Cash and cash equivalents, together with restricted cash, increased from US$186.2 million at the end of first quarter of 2023 to US$194.1 million at the end of the second quarter of 2023.

---

This increase was mainly due to the positive cash flow in investing activities (US$20.3 million) which was driven by the sale of the PRV. This was offset by negative operating cash flows for the second quarter of 2023 (US$9.6 million) mainly driven by milestone payments of US$10.0 million, and negative cash flows due to financing activities (US$2.6 million).

Outlook

•Continued low single digit growth in annual revenues from RUCONEST®. Quarterly fluctuations are expected.

•We anticipate the CHMP to issue their opinion for leniolisib in 4Q 2023. Subject to a positive opinion, Marketing Authorisation in Europe is expected ~2 months later, followed by commercial launches in individual E.U. countries.

•We intend to submit an ECDRP filing for leniolisib with the U.K. MHRA shortly after a positive CHMP opinion, with approval expected several months later.

•Pharming will continue to allocate resources to accelerate future growth. Investments in launch preparations, commercialization and focused clinical developments for leniolisib including to support pediatric and Japanese approvals, as well as for the development of leniolisib in additional indications. These investments will continue to impact profit throughout 2023. Our current cash on hand, including the continued cash flows from RUCONEST® and Joenja® sales, are expected to be sufficient to fund these investments.

•Further details on our plans to develop leniolisib in additional indications to be provided in 2H 2023.

•Investments and continued focus on in-licensing or acquisitions of mid to late-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 2023 is provided.

Notes to the condensed consolidated interim financial statements

For the period ended June 30, 2023

1.Company information

Pharming Group N.V. is a limited liability public company which is listed on Euronext Amsterdam (PHARM) and on the NASDAQ (PHAR), with its headquarters and registered office located at:

Darwinweg 24

2333 CR Leiden

The Netherlands

2.Statement of compliance

The consolidated interim financial statements for the six-month period ended June 30, 2023, have been prepared in accordance with International Accounting Standard IAS 34, Interim financial reporting. The condensed consolidated interim financial statements should be read in conjunction with the annual financial statements for the year ended December 31, 2022, which have been prepared in accordance with International Financial Reporting Standards (EU-IFRS) and IFRS interpretations committee (IFRS IC) interpretations applicable to companies reporting under IFRS as issued by the International Accounting Standards Board (IASB) and valid as of the balance sheet date.

These condensed consolidated interim financial statements were authorized for issue by the Board of Directors on August 2, 2023.

The published figures in these condensed consolidated interim financial statements are unaudited.

3.Accounting policies

Accounting policies are consistent with those of the financial statements for the year ended December 31, 2022.

4.Estimates and judgements

The preparation of interim financial statements in conformity with IAS 34 and Book 2 Title 9 of the Dutch Civil Code requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Company’s accounting policies. In preparing these condensed consolidated interim financial statements, the significant judgements made by management in applying the Company’s accounting policies were the same as those applied to the consolidated financial statements for the year ended December 31, 2022.

5.Going concern

In preparing and finishing the interim financial statements the Board of Directors of Pharming have assessed the Company’s ability to fund its operations for a period of at least twelve months after the date the interim financial statements are issued. Based upon the assessment on a going concern basis, the Company has concluded that funding of its operations for a period of twelve months, after the date the interim financial statements are issued, is realistic and achievable. Overall, based on the outcome of this assessment, the interim financial statements have been prepared on a going concern basis.

6.Seasonality of operations

Seasonality has no material impact on Company’s interim financial statements.

---

7.Segment information

Segments have changed as compared to the segments reported in our Annual Report 2022 due to the Joenja® launch. The Board of Directors consider the business from both a product and geographic perspective. From a product perspective, the Company’s business is related to RUCONEST® and Joenja®. From a geographic perspective, the Company is operating in the U.S., Europe and RoW. The Board of Directors primarily measures revenues and gross profit to assess the performance of the geographic areas. Operating costs as well as non-current assets are not sub-allocated to the geographic areas.

Total revenues and gross profit per geographic segment for the period ended June 30:

Amounts in US$ ‘000			1H 2023			1H 2022
Revenues:
US			94,824			94,136
Europe			2,266			2,293
RoW			348			334
Total revenues			97,438			96,763
Gross profit:
US			86,864			86,329
Europe			606			1,293
RoW			169			235
Total gross profit			87,639			87,857

US			3,792			—
Europe			—			—
RoW			—			—
Total			3,792			—
Total Net revenues			97,438			96,763

8.Other income

Other income increased by US$7.5 million in the first half of 2023 to US$22.5 million as compared to US$15.0 million the first half of 2022. The main reason was the gain on the sale of the PRV to Novartis as part of the license agreement (US$21.1 million) in 2023. In 2022, Pharming reduced its minority stake in BioConnection from 43.85% to 22.98%. As a result of this one-off transaction, Pharming recognized a gain of US$12.8 million.

9.Expenses by nature

21

---

Cost of sales in the first half year of 2023 were US$9.8 million versus US$8.9 million for the first half of 2022 and relates to actual product sales of RUCONEST® and Joenja®.

Other operating costs increased to US$118.5 million in the first half of 2023 compared to US$82.2 million in the first half year of 2022.

This was mainly due to the milestone payments for Joenja® (US$10.5 million). A further US$7.3 million expense increase is directly related to leniolisib in the form of increased R&D spent, marketing cost, market access costs and the commencement of the amortization of acquired rights. An increase of US$16.3 million is related to an increase in payroll and general expense, which is in large part driven by an expansion of the organization as a result of the launch and further commercialization of leniolisib but is also in part driven by inflation. The remainder of the increase is due to the increased IT cost (US$1.3 million) and due to incidental cost relating to the discontinuation of a product lead for Pompe disease (US$0.8 million).

Employee benefits

Employee benefits are charged to research and development costs, general and administrative costs, or marketing and sales costs based on the nature of the services provided.

Depreciation and amortization charges

Amounts in US$ ‘000			1H 2023			1H 2022
Property, plant and equipment			(713)			(877)
Right-of-use assets			(1,809)			(1,135)
Intangible assets			(2,946)			(2,251)
Total			(5,468)			(4,263)

The increase in the depreciation charges of right-of-use assets in 1H 2023 compared to 1H 2022 mainly resulted from the commencement of depreciation of the lease contract for the DSP facility at Pivot Park, Oss in October 2022.

The increase in amortization of intangible assets is mainly due to the commencement of the amortization of the leniolisib license in April 2023, amounting to US$0.4 million.

10.Financial income (expenses)

Amounts in US$ ‘000			1H 2023			1H 2022
Foreign currency results			—			6,474
Interest income			799			—
Other financial income			799			6,474
Foreign currency results			(2,271)			—
Interest on convertible bonds			(2,414)			(2,434)
Other interest expenses			(555)			(295)
Other financial expenses			(14)			(51)
Other financial expenses			(5,254)			(2,780)
Total other financial income and expenses			(4,455)			3,694

Foreign currency results mainly stem from fluctuations in the EUR/USD exchange rate. The EURO got stronger over the course of 2023 where it weakened over the course of 2022. This impacts the revaluation of the bank balances in US dollars incorporated in EURO functional currency entities and the receivables and payables in EURO incorporated in our USD functional currency entity.

22

---

11.Income tax (expenses)

Income tax expenses are recognized in each interim period based on the best estimate of the weighted average annual income tax rate expected for the full financial year.

12.Investments

Investments accounted for using the equity method

The asset relates to an investment in the ordinary shares of BioConnection Investments B.V. In the Board of Directors’ judgement, the investment in BioConnection constitutes an investment in an associated company and is therefore not consolidated, as Pharming has significant influence but does not have control of BioConnection and is embargoed by a shareholder’s agreement between the shareholders of BioConnection from influencing any activity between the two parties which is in any significant way different from the relationship which existed between the two prior to the investment.

The carrying amount of this investment has changed as follows:

Amounts in US $ ‘000			June 30, 2023			December 31, 2022
Balance at January 1			2,501			7,201
Release of financial guarantee			—			(153)
Dilution of equity stake			—			(2,991)
Share in net profit (loss) for the period			(469)			(1,083)
Currency translation			39			(473)
Balance at end of period			2,070			2,501

Investment in debt instruments designated as at FVTPL

The asset relates to the preference share in BioConnection Investments B.V. The Board of Directors made an assessment on the accounting treatment of the preference share obtained. The Board concluded that the asset should be recognized as a financial asset (debt instrument) measured at initial recognition at fair value, subsequently measured at fair value through profit and loss. The fair value is calculated on a yearly basis using the forward-looking Black-Scholes-Merton (“BSM”) financial instrument pricing framework. No events or matters are known as of the date of this report which would lead to a significant impact in the fair value of the asset, compared to December 31, 2022.

The carrying amount of this investment has changed as follows:

Amounts in US $ ‘000			June 30, 2023			December 31, 2022
Balance at January 1			6,827			—
Investment			—			7,933
Fair value changes			—			(1,185)
Currency translation			113			79
Balance at end of period			6,940			6,827

Investment in equity instruments designated as at FVTOCI

The Group holds 1,0 per cent of the ordinary share capital of Orchard Therapeutics, a global gene therapy leader. The shares were acquired as of July 1, 2021, as part of a strategic collaboration between Pharming Group N.V. and Orchard Therapeutics to research, develop, manufacture and commercialize OTL-105, a newly disclosed investigational ex-vivo autologous hematopoietic stem cell (HSC) gene therapy for the treatment of

23

---

hereditary angioedema (HAE), a life-threatening rare disorder that causes recurring swelling attacks in the face, throat, extremities and abdomen.

The Board of Directors do not consider that the Group is able to exercise significant influence over Orchard Therapeutics as the other 99.0 percent of the ordinary share capital is publicly traded at the Nasdaq stock exchange (Nasdaq: ORTX).

The carrying amount of this investment has changed as follows:

Amounts in US $ ‘000			June 30, 2023			December 31, 2022
Balance at January 1			403			1,449
Fair value adjustments through OCI			138			(950)
Currency translation			98			(96)
Balance at end of period			640			403

13.Deferred tax assets

The deferred tax asset increased mainly due to the addition of the current year loss to the DTA for Net operating losses.

14.Inventories

Inventories include batches of Joenja® and RUCONEST® and relating work in progress which are available for production.

Amounts in US$ ‘000			June 30, 2023			December 31, 2022
Finished goods			20,900			12,460
Work in progress			31,264			29,553
Raw materials			878			313
Balance at end of period			53,042			42,326

Changes in the adjustment to net realizable value:

Addition to impairment			(1,490)			(164)
Release of impairment			15			312
Usage of impairment			583			195
Currency translation			(34)			134
Balance at end of period			(2,897)			(1,971)

The inventory valuation at June 30, 2023, of US$53.0 million is stated net of an impairment of US$2.9 million (2022: US$2.0 million). The impairment includes an impairment for obsolescence and an impairment to write inventories down to their net realizable value.

24

---

Inventories are available for use in commercial, preclinical and clinical activities. Estimates have been made with respect to the ultimate use or sale of product, taking into account current and expected sales as well as preclinical and clinical programs. These estimates are reflected in the additions to the impairment.

The costs of vials used in preclinical and clinical programs are presented under the research and development costs.

The main portion of inventories at June 30, 2023, have expiration dates starting beyond 2023 and are all expected to be sold and/or used before expiration.
