we have already engaged in partnering discussions to develop and market Imeglimin in China, the world's second-largest type 2 diabetes market, and other regions where Imeglimin can potentially be quickly developed and approved. We are also looking forward to the results of the discussions by Sumitomo Pharma with the regulatory authorities in Japan on revising TWYMEEG® package insert for type 2 diabetic patients with renal impairment, anticipated in FY 20243 . For PXL770 and PXL065, we aim to finalize discussions with several potential partners before deciding on our investment decisions and development strategies," stated Thomas Kuhn, Chief Executive Officer of Poxel.

TWYMEEG® (Imeglimin)

• For the quarter ended June 2024, TWYMEEG® gross sales in Japan increased by 62% to JPY 1.7 billion (EUR 10.1 million)4 over the prior quarter sales of JPY 1.1 billion (EUR 6.6 million)5 as reported by Sumitomo Pharma.
• For its FY 2024³ , Sumitomo Pharma forecasts6 gross sales for TWYMEEG® of JPY 11.3 billion (EUR 69.1 million)²which would represent a 150% increase over FY 2023 TWYMEEG® gross sales.
• During Sumitomo Pharma FY 2024³ , Poxel expects TWYMEEG® net sales in Japan to reach at least JPY 5 billion (EUR 31.3 million)⁴ entitling Poxel to receive 10% royalties on all TWYMEEG® net sales and a sales-based payment of JPY 500 million (EUR 3.1 million)⁴ . Based on this FY 2024 forecast, TWYMEEG® net sales could also reach JPY 10 billion (EUR 62.6 million)⁴ entitling Poxel to receive 12% royalties on all TWYMEEG® net sales and a second sales-based payment of JPY 1 billion (EUR 6.3 million)⁴ . Based on the recent royalty monetization agreement with OrbiMed, these proceeds for FY2024 will go the reimbursement of the bonds issuance. Beyond 2024, Poxel expects to receive escalating double-digit royalties as well as additional sales-based payments upon achievement of contractually based sales thresholds.
• As announced on August 7, 2024, topline results obtained from the postmarketing clinical study, TWINKLE (TWYMEEG® in diabetic patients with renal impairment: A post-marketing long-term study) conducted by Sumitomo Pharma in Japanese type 2 diabetic patients with renal impairment confirmed TWYMEEG®'s safety and tolerability profile, which is consistent with prior clinical studies in the general type 2 diabetes population. Based on these results, Sumitomo Pharma is planning to conduct discussions with the regulatory authorities in Japan during its FY 2024³ , on revising TWYMEEG® package insert for patients with renal impairment with eGFR (estimated glomerular filtration rate) less than 45 ml/min/1.73m² .

Royalty monetization agreement based on TWYMEEG® sales with OrbiMed, and concurrent debt restructuring with IPF Partners and PGE banks9

• Under the terms of the agreement, Poxel received a gross upfront payment of USD 50 million from the OrbiMed funds in exchange for an issuance of its bonds in the same aggregate amount. From such proceeds, a deposit of USD 7.5 million has been made by the Company into a deposit account, from which USD 1.25 million will be withdrawn quarterly and paid in partial repayment of the bonds issued to OrbiMed, until net sales of TWYMEEG® reach JPY 5 billion (USD 31.3 million⁴ ), at which point OrbiMed will begin to receive sales-based payments and royalties (anticipated in early 2025, based on the expected achievement of this sales threshold by the end of 2024³ ). The residual amount of the deposit will then be available to the Company, in addition to the USD 42.5 million deposit received upon signature of the agreement.
• For the bonds issued by Poxel, the OrbiMed funds will receive (i) royalties payable by Sumitomo Pharma on net sales of TWYMEEG® in Japan, net of Poxel's obligation to Merck Serono, (ii) sales-based payments due by Sumitomo Pharma in connection with the commercialization of TWYMEEG® in Japan, and (iii) a portion of the cash flows received by the Company, in the event of partnership for the development and commercialization of Imeglimin in Asian countries other than Japan⁷ .
• The agreement will expire, and the bonds deemed repaid once OrbiMed receives a capped return equivalent to 2 times its investment, i.e. USD 100 million, plus specified expenses, if any. Upon such repayment, Poxel will regain full rights to TWYMEEG® royalties in Japan and to any sales-based commercial payments and will use the majority of these proceeds to repay the outstanding amount owed to IPF Partners.

• Part of the bonds issuance amount from this transaction was used to reduce significantly the Company's debt towards IPF Partners and the PGE banks:
  • (i) EUR 23.7 million for partial repayment of IPF debt, reducing it to EUR 12.3 million; and
  • (ii) EUR 2.8 million for partial repayment of the debt to the banks that granted the PGE Loan, reducing it to EUR 3 million.

Consequently, the Company amended its agreements respectively with IPF Partners and the banks that granted a PGE loan for the repayment of the outstanding principal of each of these debts.

Poxel reported revenues of EUR 2.0 million for the year ended December 31, 2023, as compared to EUR 0.674 thousand during the corresponding period in 2022.

R&D expenses totaled EUR 3.8 million in 2023, as compared to EUR 12.4 million in 2022. The 2023 decrease primarily reflects the end, in 2022, of the positive Phase 2 DESTINY study evaluating PXL065 in MASH.

R&D costs are net of the R&D Tax Credit (CIR) and other subsidies that resulted in income of EUR 0.6 million in 2023, as compared to EUR 1.5 million in 2022.

As presented in the Company's half-yearly financial results 2023, the amount of amortization and depreciation of intangible assets includes exclusively the impairment of PXL065 for EUR 16.6 million. This impairment translates the Company's need to obtain additional financing to pursue its development plan in MASH or ALD, its current market capitalization and the macroeconomic context in which it operates. However, the Company considers that the potential of PXL065 in its targeted indications remains unchanged and very promising.

General and administrative expenses totaled EUR 8.4 million in 2023, as compared to EUR 9.4 million in 2022.

The financial loss amounted to EUR 6.3 million in 2023, as compared to a loss of EUR 9.5 million in 2022. It primarily reflects the interests attached to the Company indebtedness.
