Leiden, the Netherlands, October 22, 2026: Pharming Group N.V. (Euronext Amsterdam: PHARM/Nasdaq: PHAR), a global biotechnology company focused on rare immune and genetic diseases, today announces preliminary, unaudited revenue and select financial information for the three months ended September 30, 2026. Pharming will report its full preliminary (unaudited) financial results for the third quarter 2026 and provide a business update on October 27, 2026, brought forward from November 5, 2026 following results indicating revenue above and total operating expenses below analyst consensus.

Total revenues for the third quarter 2026 are expected to be approximately US$117.6 million, compared with US$97.3 million in the third quarter of 2025. This represents growth of approximately 21% year-on-year, reflecting strong performance from RUCONEST® and Joenja®.

Third quarter revenues comprise approximately US$93.8 million from RUCONEST, a 14% increase compared to the third quarter of 2025 and a 30% increase compared to the second quarter of 2026, and US$23.8 million from Joenja®, a 58% increase compared to the third quarter of 2025.

The RUCONEST revenue performance reflects stabilization and continued recovery of demand in the US, early seasonal increase in channel inventory at a single U.S. specialty pharmacy customer following significant drawdowns earlier in the year, and the completion of the planned withdrawal from non-U.S. markets.

Joenja revenue growth was driven by continued strong growth in the number of U.S. patients on paid therapy, significantly increased international demand - including from launches in Germany and Japan during the quarter and continued penetration in the U.K. - with temporary benefit from ordering patterns in other international markets.

Total operating expenses for the third quarter are expected to be approximately US$74.6 million, in line with US$74.5 million in the third quarter 2025. This performance is reflective of efficient scaling of the business.

Full-year 2026 outlook
Tightened 2026 total revenue guidance to between US$380 million and US$390 million (1% to 4% growth) from prior US$375 million to US$395 million (0% to 5% growth) and lowered total operating expense guidance to between US$310 million and US$315 million (0% to 1% growth) from prior US$315 million to US$320 million (1% to 3% growth).

Clinical updates
At ESID 2026, Pharming presented positive Phase II data for leniolisib in patients with genetically defined primary immunodeficiencies (PIDs) with immune dysregulation linked to PI3Kδ signaling; Pharming expects topline Phase II results from its separate trial in CVID patients with immune dysregulation, with or without an identified genetic cause, in November 2026. We are working towards a single registrational Phase III trial in the broader CVID indication, incorporating patient populations from both studies. The estimated prevalence rate for CVID with immune dysregulation is approximately 39 patients per million, compared with approximately 1.5 patients per million for APDS, representing substantial growth potential for Joenja.

For Napazimone (KL1333) for mtDNA-driven mitochondrial disease, we expect approximately 145 of the planned 180 subjects to be enrolled in the pivotal FALCON clinical trial by the end of 2026. We now expect enrollment to be completed in the first half of 2027. Topline results from the pivotal FALCON study are expected approximately one year after the completion of enrollment.

Pharming will report third quarter 2026 financial results and provide a business update on October 27, 2026.
