JERSEY CITY, N.J., September 18, 2024 – Organon (NYSE: OGN), a global
healthcare company with a mission to improve the health of women throughout
their lives, and Dermavant Sciences Ltd. announced today that they have
entered into a definitive agreement, under which Organon will acquire
Dermavant, a Roivant (NASDAQ: ROIV) company dedicated to developing and
commercializing innovative therapeutics in immuno-dermatology.

Dermavant’s novel product, VTAMA® (tapinarof) cream, 1%, for the topical
treatment of mild, moderate, and severe plaque psoriasis in adults, was
approved by the U.S. Food and Drug Administration (FDA) in May 2022. VTAMA
cream is a once-daily, steroid-free, topical applied to affected areas with
no safety label warnings or precautions and without restrictions on location
and duration of use or body surface area. The FDA is reviewing a
Supplemental New Drug Application (sNDA) for VTAMA cream as a potential
treatment for atopic dermatitis (AD) in adults and children two years of age
and older, with Prescription Drug User Fee Act (“PDUFA”) action expected in
the fourth quarter of calendar year 2024.

Psoriasis is a common chronic inflammatory skin disease affecting over 8
million Americans 20 years of age or older ¹ and 125 million
people worldwide². Atopic dermatitis is one of the most common
inflammatory skin conditions impacting approximately 16.5 million adults and
more than 9.6 million children in the U.S. ³ In adults, women are
impacted disproportionately⁴.

Psoriasis presents a significant impact to quality of life ⁵ and
atopic dermatitis is associated with a higher disease burden ⁶
for women compared to men.

“We look forward to combining Dermavant’s strong dermatology commercial and
field medical organization in the U.S., with Organon’s market access
capabilities, regulatory expertise and worldwide commercial reach. This will
allow us to bring VTAMA cream, a patient-focused innovation in dermatology,
providing an effective, well-tolerated, non-steroidal treatment option to
the millions of people living with plaque psoriasis and potentially atopic
dermatitis,” said Kevin Ali, Organon Chief Executive Officer. “The
acquisition will deliver on Organon’s objective of improving the health of
women throughout their life stages by investing in treatments for conditions
that affect women differently.”

“This is another example of Roivant’s ability to offer creative win-win
collaborations. We are able to meet Organon’s structural objectives and to
create a transaction that is very attractive to both Roivant and Dermavant
stakeholders, while still preserving meaningful economics tied to the
potential future success of VTAMA,” said Matt Gline, Chief Executive Officer
of Roivant. “Additionally, we are excited for VTAMA cream to benefit from
Organon’s commercial scale. We believe they have the capabilities and reach
to ensure patients globally can access this important medicine.”

“This is an unparalleled opportunity for continued growth and innovation for
Dermavant, preserving our values and vision and allowing them to thrive in
the new structure at Organon. We set out to revolutionize the standard of
care in dermatology, and we delivered—becoming the #1 branded topical for
plaque psoriasis within just two months after launching VTAMA cream, and
providing over 275,000 patients with the relief they desperately needed,”
said Todd Zavodnick, Chief Executive Officer of Dermavant. “I am certain
that this merger will provide us the scope and global scale to unleash the
potential of VTAMA cream.”

“We structured the deal economics to be heavily weighted towards
success-based milestones and royalties, similar to other transactions we
have executed to date. This is consistent with our commitment to disciplined
capital allocation as we look to continue to reduce our leverage, but also
strategically add growth assets,” said Matthew Walsh, Organon Chief
Financial Officer.

Terms of the
Transaction

Organon has agreed to acquire Dermavant for aggregate consideration of up to
approximately

$1.2 billion, with an upfront payment of $175 million and a $75 million
milestone payment upon regulatory approval in AD, as well as payments of up
to $950 million for the achievements of certain commercial milestones. In
addition, Organon will pay Dermavant shareholders tiered royalties on net
sales. Dermavant owns the rights to VTAMA cream globally excluding China and
has out licensed Japan rights.

Completion of the transaction is subject to review under the
Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions.
Closing of the transaction is currently expected to take place in the fourth
quarter of 2024. Upon closing of the transaction, as part of the purchase
price consideration, Organon would assume Dermavant liabilities with an
approximate value of $286 million reported by Roivant as of June 30, 2024,
which would be subject to fair value accounting by Organon. Given the
transaction is expected to close in the fourth quarter 2024, revenue
contribution from VTAMA as well as expenses associated with onboarding the
product are not expected to impact the full year 2024 non-GAAP guidance
ranges provided on August 6^th, 2024. The transaction is expected
to be modestly dilutive to Adjusted EBITDA in 2025, turning accretive in
2026. Organon expects net leverage to be elevated above 4.0x as a result of
the transaction. The transaction is not expected to result in a revision to
Organon’s capital allocation priorities.

Roivant was represented by Freshfields Bruckhaus Deringer LLP as legal
advisor and Goldman Sachs & Co. LLC as financial advisor. Organon was
represented by Covington & Burling LLP as legal advisor.

evaluated via randomized, double-blind, vehicle- controlled trials,
PSOARING-1 and 2 for psoriasis. The safety and efficacy of VTAMA for the
treatment of atopic dermatitis was also evaluated as part of the ADORING-1
and 2 Phase III clinical studies, and is currently under review with the
FDA.
