Performance Highlights[1Q(Three months) of FYE 3/2025 Results (Year on year)] Shipment volume of Semiconductors increased due to recovery in stages of market conditions.
 General Products saw increased shipments of Tin Fluoride as user's market expanded.
 Domestic purchase price of anhydrous hydrofluoric acid (AHF) rose due to higher market priceand weakened JPY.

[Full-year Forecast] For enriched boron (boron 10) in the Energy, shipments are expected from 2Q onward,
including items delayed from the previous fiscal year and shipments for new nuclear facilities.

Impurity levels of less than 1 ppt (1×10-12) are controlled by ultra-purification and ultra-cleaning
technologies
Mass production of ultra-pure chemicals for ultra-high integrated circuit

Ultra High Purity•

Hydrofluoric acid (HF) is the only chemical capable of etching out silicon oxide film•

Chemical solutions are indispensable to the semiconductor manufacturing process andHydrofluoric Acid

Ultra High Purity Buffered
Hydrofluoric Acid

require ultra-high purity•

In particular, dilute hydrofluoric acid is used in a number of semiconductor processes•

Mixed aqueous solution of hydrofluoric acid (HF) and ammonium fluoride (NH4F)•

Mainly used in processes such as etching and cleaning of insulation films•

Chemicals with etch rates ranging from tens of Å/min to thousands of Å/min can be produced

Product name(Semiconductors)

Description

Ultra-high-purity hydrofluoricacid

Chemical solutions used in the wet etching and wet cleaning of silicon wafers in the
manufacture of semiconductors, FPDs, solar cells and MEMS

Ultra-high-purity bufferedhydrofluoric acid

Mixed aqueous solution of ultra-high purity hydrofluoric acid and ammonium fluoride
solution

BHF

A chemical mixed with 50% hydrofluoric acid and 40% ammonium fluoride solutions

LL BHFBHF with various functionalities made possible by adding a surfactant

LAL BHF

BHF that contains a surfactant has enabled it to achieve extended service life and given otheradvantages by optimizing the concentration of ammonium fluoride at 17% to 20%, about half
the concentration of ammonium fluoride contained in conventional BHF.

Ex-LAL BHF

Surfactant-containing BHF (buffered hydrofluoric acid) with ammonium fluoride
concentration reduced to 5% or less and crystal precipitation in equipment suppressed

HSN BHF

Similar to LAL BHF, a chemical solution that allows silicon oxide film etching with highselectivity with respect to a silicon nitride film while having merits such as longer life22

Introduction of Our Business- Energy -Enriched Boron (Boron-10) and its features
 Natural boron is made up of two isotopes, boron-10(20%) andboron-11(80%)
 Developed technology to enrich boron-10 to over 99%
 Established mass production technology of enriched boron for the
first time in Japan(2000)
 Boron-10 has an extremely high capacity to absorb neutrons, andfurther enriching it can increase its ability to absorb neutrons.

Introduction of Our Business- Energy -Applications of Enriched Boron Compounds
 Excess reaction control of pressurized-water reactors by dissolving into primary coolingwater Neutron-absorbing material of spent nuclear fuel transportation and storage containers Material of control rods of nuclear reactors and rack material of spent nuclear fuel pools
 Water source for facilities responding to specific major accidents, etc.
 Raw material for cancer treatment drugs (BNCT: Boron Neutron Capture Therapy)

Advantages of Using Enriched Boric Acid
(1) Improvement of corrosive environment in nuclear reactors
Required 10B concentration can be secured at 1/5 of natural products.
Operation at low concentration is possible, and corrosion in facilities can be reduced.
(2) Reduction of storage costs
Heating and heat retention are required to maintain the dissolution of boric acid water.
Enriched boric acid realizes the reduction in concentration, and reduces the problem of heatretention.
In addition, the storage tank can be made smaller.

(3) More reliable control
In the event of an emergency stop, more reliable control is possible, and since boric acid isharmful to the human body and the environment, the reduction of overall amount of boric
acid is an advantage.
25

Introduction of Our Business- General Products -Tin Fluoride The GMP inspection by the USFDA for tin fluoride, an active ingredient of OTC anticaries drugs,
was completed, and we obtained official approval.
 We sell “tin fluoride” mainly in Europe and the US as a GMP-compliant productIzumi Factory's manufacturing building(Izumiotsu City, Osaka)* We expect to see big demand mainly inEurope and the US, where there is strong
interest in dental health and beauty.

 We are also developing new applications other than toothpaste(e.g., hoof sterilization)

Introduction of Our Business- New Initiatives(Electronic Materials1) -Phosphor-related Materials
 A phosphor is a substance that absorbs light energy from the outside, converts it into light of anotherwavelength, and emits it.
(Examples of applications: LED/LCD backlights, displays, etc.)
 Our LSA-61A is a red phosphor that is efficiently excited by blue light and emits a sharp red light.

Fluoride phosphor(LSA-61A)＜Display＞＜LED lighting ＞

Phosphors have an advantage over OLEDs
due to superior stability.

Adoptions of fluoride phosphors with high colorrendering properties for high-end model lighting
are picking up pace.

◆ Working to improve durability, a focus
of increasingly high-performancemini-LED and lighting applications
 The durability of the red phosphor was
improved by 50% compared with ourconventional prototype.

Our red phosphor passed initial evaluations
by some users and will undergo evaluations
for their product implementation.

 Currently promoting sample work30

Introduction of Our Business- New Initiatives(Electronic Materials2) -PCB Materials (Low Dielectric Constant Materials)
 Low-dielectric-constant materials contribute to 5G and other high-speed communications infrastructure.
 Our products are used as additives (fillers) for substrate materials such as resin.
 The higher the frequency, the more easily radio waves are attenuated and the harder it is for them toreach the intended target. To overcome this problem, there is a need to develop materials that can handle
higher frequencies.

 Examples of target applications

 CNP-P：fluoride nanoparticle dispersion solution
with low refractive index for antireflection film

 CNP-PS1 ：Developed product that helps improve
film strength (under evaluation by customers) Film for electronic devices
 Foldable tablet
 Car cockpit, etc.

Introduction of Our Business- New Initiatives(Electronic Materials4) -Antistatic agent
 Antistatic agents are additives that prevent the accumulation of static electricity when mixed with plastics
and fibers.
 Using our ionic compound synthesis technology, we developed two types of highly pure material (liquidand solid) that provides excellent antistatic performance.
 Currently promoting sample work

Surface resistance> 109 Ω / □Surface resistance> 1014 Ω / □The company’s developed product (AS series)

Antistatic testing with the company’s developed productAntistatic agents are used in a wide range of industries, including packaging, electronics, textiles, and automobiles,
because the buildup of static electricity in plastics and fibers can lead to malfunctions of electronic equipment or fires
due to dust adhesion and discharge.

Introduction of Our Business- Transportation Business -Initiatives aimed at the improvement of corporate value
1.Promoting initiatives focusing on profitability➣ Revision of low-price transactions: Revising the rates to ones commensurate with costs and revising the transactions themselves➣ Acquisition of new projects: Actively responding to inquiries, identifying potential demand of existing shippers,
collaborating with other departments, etc.

2. Construction of stable business foundations➣ We recruit with an eye on the future while looking at our age composition, and cultivate managers and senior employees
systematically.
➣ We use external training to promote the acquisition of skills and qualifications.
➣ We secure vehicles and containers by type matched to needs.

3. Continued strengthening of the compliance system➣ We prevent dangerous driving and overwork by using drive recorders and digital tachographs, and reviewing operational
management work.
➣ Enhancement of employee education, promotion of the understanding of related laws and regulations, etc.

4. Handling of the 2024-problem in logistics➣ Establishment of an internal system conforming to the “Standards for improvement of the work hours, etc., of
automobile drivers (revised in April 2024)”
