Poxel Reports Revenue for the Third Quarter of 2026

Regulatory News:

POXEL SA (Paris:POXEL) (Euronext: POXEL - FR0012432516), a clinical-stage biopharmaceutical company that has developed innovative treatments for serious chronic diseases with metabolic pathophysiology, including metabolic dysfunction-associated steatohepatitis (MASH) and rare metabolic diseases, today announces its revenue for the third quarter ended September 30, 2026, and for the first nine months of the fiscal year.

Commercial Activity Update

TWYMEEG^® (Imeglimin)

• For the quarter ended September 2026, TWYMEEG^® net sales in Japan increased by 29% to JPY 2.9 billion (€16.3 million¹) compared to sales of JPY 2.3 billion for the quarter ended September 2025, as reported by Sumitomo Pharma. Gross sales for the quarter totaled JPY 3.3 billion, up 29%.

• In the first half of its 2026 fiscal year (April–September 2026), Sumitomo Pharma’s net sales of TWYMEEG^® reached JPY 5.8 billion, up 30% from the first half of the previous fiscal year. Sumitomo Pharma expects that net sales of TWYMEEG^® could exceed JPY 10 billion for the fiscal year, entitling Poxel to receive royalties of 12% on all net sales of TWYMEEG^® and a payment of JPY 1 billion (€5.6 million¹). In accordance with the royalty monetization agreement entered with OrbiMed, the proceeds will be used exclusively to repay the bond issue.

Consolidated Revenue for the Third Quarter and the First Nine Months of 2026

• Poxel generated consolidated revenue of €1,951k for the quarter ended September 30, 2026, bringing revenue for the first nine months of 2026 to €4,453k.

• Consolidated revenue for the third quarter of 2026 includes JPY 290 million in royalties from Sumitomo Pharma, representing 10% of net sales of TWYMEEG^® in Japan, as well as a retroactive adjustment of JPY 57 million for the second quarter of 2026, resulting from the application of a 10% rate (instead of 8%) to sales for that quarter.

• Based on Sumitomo Pharma’s projections, Poxel expects to receive 12% in royalties on net sales of TWYMEEG^® in Japan during Sumitomo Pharma’s fiscal year 2026².

• Under the license agreement entered with Merck Serono, Poxel will pay Merck Serono a fixed royalty of 8% based on net sales of Imeglimin, regardless of sales volume. Since the royalty rate of 10% now in effect is higher than this 8% rate, Poxel generates positive net royalties for Sumitomo Pharma’s fiscal year 2026.

• In accordance with the royalty monetization agreement entered with OrbiMed, any positive net royalties will be used in their entirety to repay OrbiMed’s bonds. 

* Unaudited figures. The 2025 figures are presented as published in the press release dated February 11, 2026, including retroactive adjustments to royalties for the second and third quarters of 2025.

Consolidated Cash and Cash Equivalents

As of September 30, total consolidated cash and cash equivalents amounted to €388k.

Glossary

For the sake of clarity and transparency, below is a list of words and/or expressions used in this press release or in other communications from Poxel:

• Sumitomo Pharma's fiscal year runs from April to March. For example, fiscal year 2026 runs from April 1, 2026, to March 31, 2027.
• TWYMEEG Royalties: pursuant to the agreement with Sumitomo Pharma, Poxel is entitled to receive royalties from the sales of TWYMEEG (Imeglimin) in Japan
  • Sumitomo Pharma communicates gross sales of TWYMEEG, while TWYMEEG royalties are calculated on net sales;
  • Net sales represent the amount of gross sales to which potential discounts, allowances, and costs such as prepaid freight, postage, shipping, customs duties, and insurance charges are deducted;
  • Poxel is entitled to receive escalating royalties from 8% to 18% on TWYMEEG net sales from Sumitomo Pharma.
• Positive net royalties: as part of the Merck Serono licensing agreement, Poxel will pay Merck Serono a fixed 8% royalty based on the net sales of TWYMEEG, independent of the level of sales. All royalties that Poxel receives from TWYMEEG net sales above that 8% level are considered as positive net royalties. Net royalties will therefore be positive for Poxel when TWYMEEG net sales exceed JPY 5 billion in a fiscal year, and royalties reach 10% and above.
• Poxel refers to the Poxel Group as well as the three security trusts established as part of the royalty monetization and debt restructuring transactions announced on September 30, 2024.
