1. Analysis of Results of Operations
Results of operations for the current fiscal year
In the fiscal year ended March 31, 2024 (fiscal 2023), net sales were ¥36,213 million, up 8.2% year on year. The
increase is attributable to sales volume growth from domestic pharmaceuticals and from ARTZ for China andother overseas pharmaceuticals, coupled with an increase in royalty income, which offset lower sales volume of
Gel-One, an intra-articular single-injection viscosupplement for the treatment of knee osteoarthritis for the U.S.
market, and a decline in overseas sales in the LAL business.
Operating income fell 79.5% year on year to ¥433 million, a decline mainly attributable to an increase in the costof sales ratio due to an inventory write-down, bringing forward of facilities maintenance to strengthen the
production system, and higher expenses in the LAL business. Ordinary income fell 44.9% year on year to ¥1,691
million, while net income attributable to owners of parent fell 2.2% to ¥2,186 million.

1) Net sales by segment
Seikagaku has adopted a business model of focusing management resources on R&D and manufacturing byforming alliances with domestic and overseas companies that have expertise in each product field andentrusting sales to these business partners rather than having an in-house pharmaceuticals sales division.
In view of this business structure, in addition to reporting product sales from Seikagaku to business partners,
the Company also reports on the status of sales from business partners to medical institutions using“deliveries to medical institutions” or “local sales volume” as performance indicators.

Pharmaceutical Business- Domestic Pharmaceuticals (¥12,100 million, up 7.3% year on year)
Revenue from domestic pharmaceuticals rose 7.3% year on year, mainly due to increases in the Company’s salesof ARTZ, a joint function improvement agent for knee osteoarthritis, and the OPEGAN series of ophthalmic
viscoelastic devices.
Deliveries to medical institutions of ARTZ increased year on year thanks to continued switching from competingproducts. This growth led to an increase in the Company’s sales, despite the impact of National Health Insurance(NHI) drug price reductions.
Deliveries to medical institutions of the OPEGAN series increased year on year, reflecting a continued gradualmarket growth trend accompanying population aging. This brought an increase in the Company’s sales, despite
the impact of NHI drug price reductions.
In the results for other products, the Company’s sales of MucoUp, a submucosal injection agent for endoscopic
surgery, increased, reflecting a sales partner inventory adjustment. The Company’s sales of HERNICORE, a
treatment for lumbar disc herniation, remained at the prior-year level.
Also, the Company’s sales of the joint function improvement agent JOYCLU declined year on year. The Company
issued a Dear Healthcare Professionals Letter of Rapid Safety Communication (Blue Letter) concerning JOYCLU
on June 1, 2021 and is continuing cooperative efforts with sales partner Ono Pharmaceutical Co., Ltd. to gatherside effects reports and other information and provide safety-related information.

- Overseas Pharmaceuticals (¥10,059 million, up 17.9% year on year)
Revenue from overseas pharmaceuticals rose 17.9% year on year thanks mainly to increases in the Company’ssales of ARTZ for China and SUPARTZ FX, an intra-articular 5-injection viscosupplement for the treatment ofknee osteoarthritis for the U.S. market, despite lower sales of Gel-One, an intra-articular single-injection
viscosupplement for the treatment of knee osteoarthritis for the U.S. market.
Local sales volume and the Company’s sales of Gel-One declined year on year, despite a gradual trend toward
recovery from the impact of an insurance reimbursement system change implemented in July 2022.
Local sales volume in the U.S. of SUPARTZ FX rose due to increased preference for a stable product subject tominimal price fluctuation against the backdrop of an insurance reimbursement system change. The Company’ssales rose because of the combined impact of a shipping schedule adjustment and yen depreciation.
Local sales volume of ARTZ for China rose, reflecting recovery in the patient consultation rate as the impact of4

COVID-19 dissipated. In addition, the Company’s sales rose sharply year on year, reflecting a rebound following
lower-than-normal sales in the first quarter of fiscal 2022 when a packaging material change led to an absence of
shipments and the bringing forward of product shipments originally scheduled for fiscal 2024.

- Bulk Products and Contract Development and Manufacturing Organization (¥3,083 million, up 5.7%
year on year)
Sales increased due to higher sales of contract development and manufacturing and other services of overseas
subsidiary Dalton Chemical Laboratories, Inc. coupled with yen depreciation.
As a result of these developments and an increase in royalty income (¥699 million, -), sales from thePharmaceuticals business segment rose 14.2% year on year to ¥25,942 million.

LAL Business
Sales from the LAL business segment decreased 4.3% year on year to ¥10,271 million. Although sales in Japan
were at the prior-year level, sales at overseas subsidiary Associates of Cape Cod, Inc. declined as special demand
accompanying the spread of COVID-19 infection subsided.

2) Research and Development Activities
To contribute to healthy and fulfilling lives for people around the world, the Seikagaku Group focuses its researchand development on glycoscience as its area of specialization and aims to create original pharmaceuticals andmedical devices.
The Group will aim to achieve early and continuous launching of new products, which hold the key to futurebusiness growth, by focusing on application of Seikagaku’s original glycoscience-related basic technologies tocreate new development themes in existing fields as well as innovative research themes, including in new disease
areas, and by pursuing various alliances.
Total R&D expenses in fiscal 2023 were ¥7,484 million, or 21.1% of net sales (excluding royalties), and thenumber of R&D personnel was 195, or 19.7% of the total number of employees, at March 31, 2024.
The status of progress of principal R&D activities is described below.

SI-6603 (treatment for lumbar disc herniation: developed in the U.S.)
Follow-up observation in an additional Phase III clinical study was completed in March 2023, and topline results
indicating statistically significant improvement in the primary endpoint were obtained in May. Preparations are
currently underway to obtain approval.
SI-6603, which contains condoliase as its active pharmaceutical ingredient, is a therapeutic agent directly injected
into the lumbar disc. It does not require general anesthesia and is less invasive to the patient than surgical treatment.
Since a single-injection treatment is expected to improve the symptoms of lumbar disc herniation, the Company
aims to provide SI-6603 as a new treatment option.

SI-614 (treatment for dry eye: developed in the U.S.)
Statistically significant improvement in the primary endpoint of a Phase III clinical study being conducted since
May 2022 was not observed.
Seikagaku is considering the policy on future development based on the data obtained.

SI-613 (treatment for osteoarthritis: developed in the U.S., China, and South Korea)
SI-613-ETP (treatment for enthesopathy: developed in Japan)
SI-613
The Company will consider the future direction for development in the U.S., China, and South Korea whileassessing progress with identification of the cause of shock or anaphylaxis of JOYCLE.
SI-613-ETP
The primary efficacy endpoint in a late-stage Phase II clinical trial in Japan of SI-613-ETP for the treatment
enthesopathy was not met, and the Company will prioritize identification of the cause of shock or anaphylaxis of
JOYCLE. For these reasons, development of SI-613-ETP was discontinued in February 2022.
5

SI-613 is a formulation in which hyaluronic acid and diclofenac (an anti-inflammatory agent) are chemically boundusing Seikagaku’s own proprietary technology. It is expected to improve symptoms associated with osteoarthritis
and enthesopathy by releasing diclofenac by hydrolysis.

SI-722 (treatment for interstitial cystitis: developed in the U.S.)
Seikagaku is considering the policy on future development based on data obtained in Phase I/II clinical studies.
SI-722 is a novel chemical compound in which a steroid is conjugated with chondroitin sulfate using Seikagaku's
proprietary glycosaminoglycan modification technology and drug delivery systems. SI-722 injected into thebladder is thought to demonstrate long-lasting improvement in the conditions of frequent urination and bladderpain by releasing a steroid with an anti-inflammatory effect.

SI-449 (adhesion barrier: developed in Japan)
In a pivotal study in the field of gastroenterological surgery being conducted since May 2020, results showing
statistically significant adhesion prevention performance in both the primary effectiveness endpoint of the presenceor absence of post-operative adhesions and the secondary effectiveness endpoints of severity and extent ofadhesions were obtained in July 2023. No safety issues were observed.
Also, no major problems were found with safety and operability of SI-449 in laparoscopic surgery in a pilot study
in the field of gynecology conducted for the purpose of expanding the scope of indications for the product. The
Company is now proceeding with selection of a sales partner and preparations for a new drug application (NDA)at an early date.
SI-449 is a powdered medical device whose main ingredient is cross-linked chondroitin sulfate developed using
Seikagaku’s own proprietary glycosaminoglycan cross-linking technology. It has the property of absorbing
moisture and swelling, and is expected to prevent post-operative adhesion formation in surgery by forming a barrier
between the surgical wound site and surrounding tissues after application. The Company will proceed with
development of SI-449 with a view to introducing it globally, not only in Japan.There is no substantial change inthe other R&D activities.

2. Forecasts for Fiscal 2024
For fiscal 2024 (April 1, 2024 to March 31, 2025), the Company forecasts consolidated net sales of ¥40,000 million,
an increase of 10.5% from the previous year. The main driver of the projected revenue increase is an expected
increase in royalty income. Pharmaceutical sales are projected to decline year on year due to the impact of NHI
price reductions for domestic pharmaceuticals and shipment adjustments affecting certain overseas
pharmaceuticals.
As for the earnings outlook, the Company forecasts operating income to rise by 812.1% year on year to ¥3,950
million, ordinary income to rise by 169.0% to ¥4,550 million, and net income attributable to owners of parent torise by 57.8% to ¥3,450 million, mainly as a result of the expected increase in royalty income. At the same time,
the Company forecasts increases in SG&A expenses and income taxes to result mainly from higher personnel
expenses accompanying development and enhancement of an expanded production, systems-related expenses, andtax expenses.
The Company Forecasts R&D expenses of ¥6,900 million, a decrease of 7.8% year on year, and a ratio of R&D
expenses to net sales (excluding royalty income) of 19.4%.
The exchange rate assumption used in the forecast of consolidated financial results for fiscal 2024 is ¥145 to the
U.S. dollar.
Note: The above forecast has been prepared on the basis of economic circumstances, market trends, and otherassumptions made at the time of release of this document. Actual results may differ from the forecast due to avariety of factors.

3. Issues Facing the Company
While the abrupt changes to the business environment surrounding the pharmaceuticals industry are continues tobe extremely difficult, progress in measures to control medical expenses of starting with a drastic reform of the
NHI drug pricing system in Japan, intensity of competition among firms the diversifying of treatment options,and degree of difficulty of new drug development increases in the inside cost of research and development whichrises. A flexible response to these times of drastic change in the operating environment will be necessary for
Seikagaku to maintain a constant growth trajectory. Also, fulfilment of social responsibilities, starting withsustainability promotion, is increasingly important for the sustainable development of society and enhancement ofcorporate value, and responding to this societal trend is a matter of urgent importance.

Overview of the mid-term management plan (fiscal 2022 to fiscal 2025)
1) Business Goal
Seikagaku has positioned the period of the current mid-term management plan, the four-year period beginningwith the fiscal year ended March 31, 2023 (fiscal 2022), as a period for achieving growth. Building on a foundation
solidified during the period of the previous management plan, Seikagaku aims to cultivate the ability to maintaina constant growth trajectory and achieve record-high business results in the final year of the plan by implementing
key measures set out in the plan.

2) Key measures
Seikagaku will implement the following five key measures to nurture the capability to maintain a constant growthtrajectory.
① Maximize the product value of SI-6603 (treatment for lumbar disc herniation)
Take maximum advantage of SEIKAGAKU NORTH AMERICA CORPORATION, established in Canada forthe purpose of obtaining approval in the U.S. and launching SI-6603, a treatment for lumbar disc herniation,
to ensure a prompt and accurate NDA and response to regulatory review. Also proceed with sales preparations
and pursue maximization of product value through early penetration at medical institutions in close cooperation

Also, to increase the probability ofsuccess of these efforts, pursue various alliances aimed at making early progress. At the same time, advanceexisting pipelines with the aim of obtaining approval and introducing in the U.S. SI-6603 (a treatment for
lumbar disc herniation), completing a Phase III clinical study in the U.S. of SI-614 (a treatment for dry eye),and obtaining approval in Japan and initiating a clinical study in the U.S. of SI-449 (an adhesion barrier).
*GAG: Glycosaminoglycans, such as hyaluronic acid and chondroitin sulfate, which are structural components know as
glycoconjugates.

③ Maintain and enhance the business value of joint function improving agents
Strive to maintain and enhance the business potential of the core products that support business management
by increasing the presence of Seikagaku products in the mainstay domestic market for joint function improving
agents. Since the domestic pharmaceuticals business is greatly affected by NHI drug price reductions, cost
structure improvement is essential. Seikagaku will further proceed with product material specification changes,
which help ensure continuity of product supply, manufacturing process efficiency improvement, and othermeasures. Seikagaku will also continue gathering and providing safety information on the joint function
improving agent JOYCLU with the aim of contributing to appropriate prescription on the basis of clinicalresearch findings.
