Paris (France)
and Cambridge (Massachusetts, United States), September 11, 2026 at 7.00 AM (CET) – Biophytis SA (Euronext Growth Paris : ALBPS),
(“Biophytis” or the “Company”), a pioneer in the development of transformative therapies
impacting longevity, today announces the completion of a capital increase through the issue of new shares, accompanied by share subscription
warrants, with the removal of the preferential subscription rights of the Company’s existing shareholders in favor of several institutional
investors, for a total gross amount of €5.3 million, including €4.75 million cash and €0.55 million Hexagon debt roll
(the “Placement”).
The Placement funds
the launch and much of the execution of Biophytis’ Phase 2 OBA clinical study in obesity, marking the next major clinical milestone
for BIO101. The OBA program is designed to evaluate BIO101 as a potential complement to GLP-1 receptor agonist therapies such as Wegovy
and Zepbound, with the aim of preserving muscle strength and mobility during weight loss and assessing its potential to limit weight
rebound following treatment discontinuation. The Placement extends the Group’s cash runway to Q1 2028 allowing Phase 2 obesity
clinical trial initiation targeted for Q1 2027 and reaching top-line data in first half 2028.
In parallel to
launching the OBA trial, Biophytis will continue to advance BIO101 in sarcopenia through the preparation of the Phase 3 SARA-31 study,
pursuing remaining regulatory authorizations and implementing its joint venture in Hong Kong. These two programs reflect the Group’s
strategy of developing BIO101 across complementary muscular and metabolic indications, while relying on strong regional partnerships
to broaden its clinical and commercial reach.
Stanislas
Veillet, Chairman and CEO of Biophytis, stated: ” This financing lets us move the obesity trial from regulatory and operational
readiness into clinical execution. As GLP-1 therapies reshape obesity treatment, we believe the next frontier is not just weight loss,
but also strength and mobility preservation and sustaining those benefits over time. We believe BIO101 has the potential to address these
needs. In parallel, we continue to advance our Phase 3 sarcopenia program through our regulatory work and the implementation of our Hong
Kong joint venture. Together, these programs reflect our vision for Biophytis: focusing on clearly defined, value-creating clinical milestones
backed by partnerships that can extend our reach across major markets.”
Use of proceeds:
The company intends
to use the net proceeds from the Placement to:
| - | Launch
and execute the OBA phase 2 study, including the enrolment of patients up to reporting
on topline results. |
| - | Cover
Biophytis’ operating and current expenses, ensuring business continuity and extending
the Company’s cash flow horizon until the first quarter of 2028. |
Terms of
the Placement
Nature and type
of the Placement: the Placement, for a total gross amount of €5,300,000.78 (including share premium), was carried out through
the issuance, without preferential subscription rights and without a priority subscription period, in favour of investors falling within
the categories defined by the 3rd resolution of the shareholders’ meeting held on November 13, 2025, of shares (the
“New Shares”) with share subscription warrants attached, four ordinary shares being accompanied by five share subscription
warrants (the “BSA” and, with the New Shares, the “ABSA”).
Number of securities
and pricing of the Placement: As part of the Placement, 101,923,092 New Shares and 127,403,865 Warrants are issued.
The issue price
of one New Share was set at € 0.052 (€0.002 of par value and € 0.050 of issue premium), representing a discount of 24.1
% compared to the weighted average price of the Company’s shares over the last ten trading days prior to the setting of the issue price.
Legal framework
of the Placement: Making use of the delegation granted by the shareholders’ meeting dated November 13, 2025 pursuant to its
third resolution, the Board of Directors, held on September 7, 2026, decided on the principle of issuing New Shares, to which BSA are
attached, with the removal of preferential subscription rights. It sub-delegated the power to launch and define the precise characteristics
of the Placement to the Company’s Chief Executive Officer.
Characteristics
of the BSA: a unit of four New Shares is accompanied by five BSA. Each BSA entitles the holder to subscribe to one new Biophytis
share, at an exercise price of €0.06 per share. The BSA may be exercised within 60 months from the issuance date.
Settlement-delivery
and admission to trading: Settlement-delivery of the ABSA is expected on September 15, 2026. The New Shares and BSA will be
immediately detached upon issuance. The New Shares and BSA are expected to be admitted to trading on Euronext Growth on September 15,
2026. The BSA will be listed under the ISIN code: FR001401AY03.
New Shares Underlying
the BSA: The new shares that may be issued upon exercise of the BSA will be ordinary shares subject to all statutory provisions and
treated as existing shares from their date of issue. They will carry current dividend rights and will be admitted to trading on the Euronext
Growth Paris market on the same listing line as the Company’s shares already listed under the same ISIN code: FR001400OLP5 – ALBPS.
Impact of
the Placement on the Company’s shareholding structure
Following the issuance
of the New Shares, the Company’s total share capital will be at €700,264.994, consisting of 350,132,497 common shares. Following
the issuance of the New Shares and the exercise of all the 127,403,865 BSA, 229,326,957 new shares will be issued for a total of 477,536,362
shares outstanding for a share capital of € 904,111.178.
101,923,092 ordinary
shares (29.1% of the Company’s current total share capital) would therefore be issued as part of the Placement (before exercise of the
BSA), or 229,326,957 ordinary shares (20.3% of the Company’s current total share capital) after exercise of all the BSA.
By way of illustration,
a shareholder holding 1% of the Company’s outstanding share capital prior to the completion of the offer and who did not participate
in the offer would hold 0.71% of the Company’s outstanding share capital and voting rights after the issuance of the ABSA, and 0.57%
of outstanding share capital and voting rights if all of the BSA are exercised.
To the best of
the Company’s knowledge, immediately prior to the completion of the Placement, the breakdown of the Company’s share capital was as follows:
| (1) | Before
the exercise of the BSA. |
| (2) | Theorical
voting rights (i.e., including treasury shares without voting rights). |
| (3) | Shares
held by Company itself under the liquidity contract. |
To the Company’s
knowledge, upon completion of the Placement (prior to the exercise of the BSA), the breakdown of the Company’s share capital will
be as follows:
| (1) | Before
the exercise of the BSA. |
| (2) | Theorical
voting rights (i.e., including treasury shares without voting rights). |
| (3) | Shares
held by Company itself under the liquidity contract. |
To the Company’s
knowledge, upon completion of the Placement (after the exercise of the BSA), the breakdown of the Company’s share capital will
be as follows:
| (1) | After
the exercise of the BSA. |
| (2) | Theorical
voting rights (i.e., including treasury shares without voting rights). |
| (3) | Shares held by Company itself
under the liquidity contract. |
Admission
to trading of the New Shares and BSA
The New Shares
and (upon request of the holder) the BSA are expected to be admitted to trading on Euronext Growth on September 15, 2026. The BSA will
be listed under the ISIN code: FR001401AY03. The New Shares and any new share resulting from the exercise of the BSA will be subject
to the provisions of the Company’s bylaws and will be assimilated to existing shares upon final completion of the Placement. They
will bear current dividend rights and will be admitted to trading on the same listing line as the Company’s existing shares under
the same ISIN code FR0012816825.
Standstill
and lock-up agreements
In connection with
the Placement, the Company has entered into a standstill agreement for a period of 45 calendar days from the settlement date of the Placement,
subject to certain customary exceptions. The Company’s directors, its chief executive officer and certain managers have signed a lock-up
agreement effective as of the date of execution of said agreement and which will continue for a period of 90 calendar days following
the date of Placement of the ABSAs in respect of their entire holdings, subject to certain customary exceptions.
