United-Guardian, Inc. is a publicly-traded (NASDAQ:UG), fully integrated research, development, and manufacturing company that 
has been supplying unique and innovative products to the personal care, health care, pharmaceutical, and industrial sectors since 
1942. The company’s products are developed and manufactured by the company’s Guardian Laboratories Division at its 50,000 
square foot facility in Hauppauge, New York. The cosmetic ingredients are marketed through a worldwide network of distributors 
and are used by many of the major multinational cosmetic companies. The pharmaceutical products are sold primarily to full-line 
drug wholesalers, which distribute them to pharmacies, hospitals, physicians, long-term care facilities, and other health care 
providers. The health care products are primarily medical lubricants marketed directly to manufacturers of medical devices 
and other medical products, which incorporate them into their finished products and distribute them to hospitals, pharmacies, 
and other health care facilities. The specialty industrial line of products was discontinued after the second quarter of 2023. The 
LUBRAJEL® line of hydrogels is the company’s most important product line and are used in both personal care and medical 
products. Innovation is a central theme of United-Guardian’s strategy. The focus, at this time, is to continue expanding the pipeline 
of classic and naturally derived hydrogel products to address unmet market and customer needs. Over the years, the company 
has been issued over 32 patents. The company currently relies primarily on proprietary manufacturing methods and product 
formulations, which are protected as trade secrets, rather than patent protection. United-Guardian has received ISO 9001:2015 
registration from DQS Inc., indicating that the company’s documented procedures and overall operations have attained the very 
high level of quality needed for this global certification level.

LETTER TO STOCKHOLDERS

Dear Stockholder:
I am pleased to report that 2024 was a stronger year for United-Guardian compared to 2023. We saw sales 
improve in both the cosmetic and medical lubricant markets. While pharmaceutical sales did not fully recover 
in 2024 due to a shutdown at our contract manufacturer for Renacidin®, we did start to recover from the deficit 
that we had seen earlier in the year. 
	
Net sales and net income increased from FY 2023 to FY 2024. Net sales increased by 12% from 
$10,885,154 in 2023 to $12,181,971 in 2024 generating net income of $3,250,875 ($0.71 per share) in 2024 
compared to $2,581,370 ($0.56 per share) in 2023. Sales of cosmetic ingredients and medical lubricants 
increased by 32% and 16%, respectively. The increase in cosmetic ingredient sales was primarily due to 
increased purchase orders from our largest distributor, Ashland Specialty Ingredients (“ASI”). ASI stated that 
there was greater demand for our products in China as a result of regaining market share at certain key 
accounts. The increase in medical lubricant sales was driven by greater demand from one of our large contract 
manufacturer customers in China. Pharmaceutical sales decreased by 5% in 2024, due to a supply disruption 
of Renacidin, our main pharmaceutical product, that we experienced at the end of 2023 and continued into the 
first quarter of 2024. This disruption impacted our sales of Renacidin for 2024. Sales began increasing once 
supply levels resumed and we saw a trend of returning sales as the year progressed. Our fourth quarter results 
were not as strong as the previous quarters in 2024, and the primary reason for this decrease was due to ASI’s 
ordering patterns. While sales to ASI’s customers remained steady, so did their inventory levels, which resulted 
in a decrease in the purchase orders we received from them in the fourth quarter.
	
We are continuing to explore the market for Renacidin by gaining valuable insights into patient product access, 
barriers limiting growth and brand awareness. Our next study, an investigation into the payer landscape, will 
begin in the second quarter of 2025. This study will explore barriers that may exist for patients to access 
Renacidin and develop strategies to mitigate the barriers, if present. We believe that obtaining a broader 
understanding of Renacidin in the marketplace will allow us to expand our sales and reach more patients. These 
studies are not only designed to increase our domestic market share but will allow us to demonstrate the potential 
value this product may have across the globe. Our wider plan is to expand Renacidin outside the United States, 
and we believe the information generated from our research will put us on a trajectory to accomplish that goal.
	
We have been actively working with our distributors to seek opportunities to expand our market position. 
We recently signed a distribution agreement with Azelis Group NV (“Azelis”) for an additional territory, South 
Korea. The Korean market is at the forefront of innovation in the skin care category, and the Azelis team is 
ideally suited to introduce our products to new customers. Azelis has already begun introducing our ingredients 
to their customers and we are hopeful that we will gain greater market share in this territory. We continue 
to have discussions with ASI on a new distribution agreement for our cosmetic ingredients. While finalizing 
this agreement has taken longer than expected, we are actively working with ASI to negotiate the terms 
of our agreement. We are hopeful that an agreement will be signed later this year. We continue to conduct 
business with ASI as we have previously, by fulfilling orders and discussing marketing strategies. We have been 
United-Guardian, Inc. Annual Report 2024  1

2  United-Guardian, Inc. Annual Report 2024
discussing the topic of tariffs with our distributors as well as internally. The situation remains fluid and is 
subject to change. We are continuing to monitor the situation closely, and we will update our stockholders 
on the potential impact on our business, if any, in the next stockholders’ letter.
	
Our Natrajel® line of sexual wellness ingredients was first introduced to the market in late 2023 and 
has been steadily gaining interest from customers. Brenntag Specialties (“Brenntag”), our marketer and 
distributor of the sexual wellness line in the Americas, has been promoting these products at trade shows 
and during customers visits. We have received positive feedback and interest, which we believe will put us 
in a strong position for growth as this market continues to gain traction among consumers. While all new 
products take time to grow, we have been very encouraged by the number of sample requests we have 
received so far and are hopeful we will receive orders for these products in 2025. We are still in the process 
of negotiating an extension to our current agreement for an additional territory in Europe.
	
We are excited to report that our marketing agreement with Azelis for our medical lubricant products in 
the UK and Ireland has been executed. Azelis has strong relationships with customers in the medical market 
and believes that our products are a natural fit for unmet needs within several medical categories. We are at 
the beginning of this process, and are preparing documentation, providing training materials and developing 
a marketing strategy. We will provide updates as we move forward. 
	
Finally, our research and marketing teams continue to develop ingredients and promote existing products 
to new customers. Based on feedback from our customers and distributors, we know that our Lubrajel® 
line of products provide multifunctional benefits with hydration, lubrication and sensory at the forefront. 
We have several new products in the later stages of development and will be providing samples to our 
distributors for feedback in the coming months. The products include a skin care ingredient designed for 
longer hydration benefits, a hair care ingredient that meets the growing need for natural ingredients and a 
new Natrajel ingredient for the sexual wellness market that addresses an unmet need. Our marketing team is 
creating documentation needed to provide a robust promotional effort, and we will provide additional updates 
once these products are launched. In addition, we are continuing to develop new products for our medical 
customers with several projects in various stages of development and our marketing team will be creating 
brochures, sample kits and training presentations to further expand our presence in the medical market.
	
We are still following our growth plan, which we believe is the best way to provide consistent growth 
to our stockholders. Our plan began in the second half of 2023 by identifying pathways for growth and 
expansion within our current markets. In 2024, we implemented key steps in our growth plan by adding 
marketing capabilities, signing a new distribution agreement, conducting studies to further our knowledge 
base, and assessing our commercialization channels. We believe that the core steps in our growth plan are 
in place, and we will continue to implement the changes needed to support our goal of growing the business.
Sincerely,
UNITED-GUARDIAN, INC.

products, medical lubricants and sexual wellness 
ingredients. Prior to July 1, 2023, the Company 
manufactured and reported sales of a line of specialty 
industrial products; however, this product line was 
discontinued after the second quarter of 2023 due 
to low sales volume with no growth prospects. 
The Company also conducts research and product 
development, primarily related to the development of 
new and unique cosmetic ingredients. The Company’s 
research and development department also modifies, 
refines, and expands the uses for existing products, 
with the goal of further developing the market for 
the Company’s products. Two major product lines, 
Lubrajel and Renacidin Irrigation Solution (“Renacidin”) 
together accounted for approximately 93% and 92% of 
the Company’s sales for the years ended December 31, 
2024 and December 31, 2023, respectively. Lubrajel 
accounted for approximately 60% and 54% of the 
Company’s sales for the years ended December 31, 
2024 and December 31, 2023, respectively, and 
Renacidin accounted for approximately 33% and 38% of 
the Company’s sales for the years ended December 31, 
2024 and December 31, 2023, respectively.
Segment Information
	
The Company operates its business under one 
operating segment, which is also its reportable 
segment. The Company’s chief operating decision 
maker (“CODM”), who is the President, reviews financial 
information presented at the consolidated level and 
decides how to allocate resources based on financial 
metrics, including net income. The measure of 
segment assets is reported on the balance sheet 
as total consolidated assets. The CODM, along with 
the Board Of Directors, use such financial metrics, 


including net income, to evaluate income generated 
from segment assets (return on assets) in deciding 
whether to reinvest profits or allocate to other parts 
of the organization, such as working capital needs, 
mandatory and discretionary capital expenditures or 
other growth opportunities that may arise that are 
in the Company’s best interest and the best interest 
of the stockholders.
 	
Net income, other financial metrics and sales 
forecasts are used to monitor budget versus actual 
results. The reported segment revenue, segment 
profit or loss and significant segment expenses are 
the same as the consolidated results disclosed on 
the consolidated statements of income.
Impact of Global Supply Chain Instability, Inflation 
and Tariffs
	
The continued supply chain instability, primarily 
caused by military tensions in the Middle East, 
continues to impact vessels’ access to the Red Sea 
and Suez Canal. Shipping experts say this crisis 
may last into the first half of 2025. The Company 
continues to work with its suppliers regarding lead 
times and is closely monitoring this situation. Although 
the Company has not yet experienced any delays in 
receiving raw materials or an increase in shipping 
costs, the Company is aware that the situation is 
fluid and could impact it at any time. If that occurs, 
the Company may experience longer lead times and 
increased shipping costs for some of its raw materials, 
which may impact future gross margins. As a result 
of this global supply chain instability, there continues 
to be uncertainty regarding the potential impact on 
the Company’s operations or financial results and its 
unable to provide an accurate estimate or projection 
as to what the future impact will be.
	
The Trump administration has communicated its 
intention to impose tariffs on many products imported 
from China, Canada and Mexico. Some of those tariffs 
went into effect on March 4, 2025. Since that time 
the Trump administration has increased some of those 
tariffs and postponed others. It has threatened to 

United-Guardian, Inc. Annual Report 2023 9
levy tariffs on additional countries, including those of 
the European Union. Many of the countries on which 
those tariffs have been levied have imposed their own 
retaliatory tariffs or threated to impose tariffs on goods 
they import from the U.S. The tariff situation remains 
fluid and is subject to modification at any time. At this 
time, it is difficult for the Company to determine the 
impact of these tariffs on its business. The Company 
will continue to monitor this situation closely.
	
While the Company obtains most of its raw 
materials and lab supplies from domestic sources, 
it has three suppliers that obtain their raw materials 
from China. These materials are not purchased by 
the Company in large quantities, and it has adequate 
stock on hand to cover the next six months. In addition, 
the Company has one direct raw material supplier 
in China; however, the raw materials purchased from 
this supplier are not in large quantities and the effect 
of this tariff would not materially impact the pricing 
of its products.
	
Many of the Company’s products are used in the 
formulation of finished products that are manufactured 
in China and then imported back into the United States 
(“U.S.”) for sale. There is the possibility that the tariffs 
levied on these finished products could result in an 
increase in their price, which could potentially impact 
demand for these products in the U.S.
	
Due to the continued uncertainty of this, any 
other tariffs that may be imposed, there continues 
to be uncertainty regarding the future impact of any 
additional tariffs on the Company’s operations or 
financial results.
Use of Estimates
	
In preparing financial statements in conformity 
with a Generally Accepted Accounting Principles in the 
United States of America (“US GAAP”), management 
is required to make estimates and assumptions that 
affect the reported amounts of assets and liabilities 
and the disclosure of contingent assets and liabilities 
at the date of the financial statements and revenue and 
expenses during the reporting period. Actual results 
could differ from those estimates. Such estimated 
items include the allowance for credit losses, reserve 
for inventory obsolescence, accrued distribution fees, 
outdated material returns, possible impairment of 
marketable securities and the allocation of overhead.
Accounts Receivable and Reserves
	
In accordance with FASB ASC Topic 326, “Financial 
Instruments—Credit Losses (Topic 326): Measurement 
of Credit Losses on Financial Instruments”, (“ASC 326”), 
the Company presents financial assets at the net 
amount expected to be collected, requiring immediate 
recognition of estimated credit losses expected to 
occur over the asset’s remaining life. This is in contrast 
to previous U.S. GAAP, under which credit losses were 
not recognized until it was probable that a loss had 
been incurred. The Company performed its expected 
credit loss calculation based on historical accounts 
receivable write-offs, including consideration of then-
existing economic conditions and expected future 
conditions. The adoption of this ASU did not have a 
significant impact on the financial statements. Prior to 
the implementation of ASU No. 2016-13, the Company 
calculated its reserve for accounts receivable by 
considering many factors including historical data, 
experience, customer types, credit worthiness and 
economic trends.
 	
The carrying amount of accounts receivable is 
reduced by an allowance for credit losses that 
reflects the Company’s best estimate of the amounts 
that will not be collected as of the balance sheet 
date. This allowance is based on the credit losses 
expected to arise over the life of the asset and is based 
on the Current Expected Credit Losses (“CECL”). At 
December 31, 2024 and 2023, the allowance for credit 
losses related to accounts receivable amounted to 
$14,342 and $16,672, respectively.
Revenue Recognition
	
The Company records revenue in accordance 
with ASC Topic 606 “Revenue from Contracts with 
Customers.” Under this guidance, revenue is recognized 
when a customer obtains control of promised goods or 
services, in an amount that reflects the consideration 
expected to be received in exchange for those goods or 
services. The Company’s principal source of revenue is 
product sales.
	
The Company’s sales, as reported, are subject to 
a variety of deductions, some of which are estimated. 
These deductions are recorded in the same period in 
which the revenue is recognized. Such deductions, 
primarily related to the sale of the Company’s 
pharmaceutical products, include chargebacks from 
the United States Department of Veterans Affairs 

10  United-Guardian, Inc. Annual Report 2023
(“VA”), rebates in connection with the Company’s 
current participation in Medicare programs, distribution 
fees, discounts, and outdated product returns. 
These deductions represent estimates of the related 
obligations and, as such, knowledge and judgment are 
required when estimating the impact of these revenue 
deductions on sales for a reporting period.
	
During 2024 and 2023, the Company participated 
in various government drug rebate programs 
related to the sale of Renacidin, its most important 
pharmaceutical product. These programs include the 
Veterans Affairs Federal Supply Schedule (“FSS”), and 
the Medicare Part D Coverage Gap Discount Program 
(“CGDP”). These programs require the Company to sell 
its product at a discounted price. The Company’s sales, 
as reported, are net of these rebates, some of which 
are estimated and are recorded in the same period that 
the revenue is recognized.
	
On January 1, 2025, the Centers for Medicare & 
Medicaid Services (“CMS”) implemented a new 
Medicare Part D Manufacturer Discount Program 
(“Discount Program”), which replaced the prior CGDP. 
The new Discount Program eliminates the coverage 
gap benefit phase, introduces pharmaceutical 
manufacturer discounts in the initial and catastrophic 
coverage phases, and lowers the cap on enrollee out-
of-pocket costs. Under the new Discount Program, 
additional rebates are expected to be owed by 
pharmaceutical manufacturers due to the restructuring 
of the benefit periods and removal of the cap that was 
in place that limited the drug manufacturer’s liability. 
The overall financial impact of this new program will 
vary depending on the products being reimbursed 
but is expected to increase Medicare Part D rebates 
for drug manufacturers. On January 31, 2024, the 
Company was notified by CMS that it qualified as a 
“specified small manufacturer” and would be entitled 
to a multi-year phase-in period during which it 
would pay a lower percentage discount on drugs 
dispensed to beneficiaries. Based on the “specified 
small manufacturer” designation, it appears, that 
based on our current level of sales through the 
Medicare Part D Program, the Company would have 
reduced rebate liabilities in years 2025 and 2026, 




with rebates gradually increasing each year until they 
reach their full value in 2031. By the end of the phase 
in period in 2031, these rebate liabilities are expected 
to significantly exceed the liabilities we have recorded 
under the CGDP in previous years.
	
As long as a valid purchase order has been 
received and future collection of the sale amount 
is reasonably assured, the Company recognizes 
revenue from sales of its products when those 
products are shipped, which is when the Company’s 
performance obligation is satisfied. The Company’s 
cosmetic products are shipped EXW from the 
Company’s facility in Hauppauge, NY, and the risk of 
loss and responsibility for the shipment passes to the 
customer upon shipment. Sales of the Company’s 
non-pharmaceutical medical products are deemed 
final upon shipment, and there is no obligation on the 
part of the Company to repurchase or allow the return 
of these goods unless they are defective. Sales of the 
Company’s pharmaceutical products are final upon 
shipment unless (a) they are found to be defective; 
(b) the product is damaged in shipping; (c) the product 
cannot be sold because it is too close to its expiration 
date; or (d) the product has expired (but it is not more 
than one year after the expiration date). This return 
policy conforms to standard pharmaceutical industry 
practice. The Company estimates an allowance for 
outdated material returns based on previous years’ 
historical returns of its pharmaceutical products.
	
The Company does not make sales on 
consignment, and the collection of the proceeds of 
the sale of any of the Company’s products is not 
contingent upon the customer being able to sell the 
goods to a third party.
	
Any allowances for returns are taken as a 
reduction of sales within the same period the revenue 
is recognized. Such allowances are determined based 
on historical experience under ASC Topic 606-10-32-8. 
At December 31, 2024 and 2023, the Company had an 
allowance of $276,732 and $247,847, respectively, for 
possible outdated material returns, which is included in 
accrued expenses. There is no asset value associated 
with these outdated material returns, as these products 
are destroyed.





United-Guardian, Inc. Annual Report 2023 11
	
The timing between recognition of revenue for 
product sales and the receipt of payment is not 
significant. The Company’s standard credit terms, 
which vary depending on the customer, range 
between 30 and 60 days. The Company recognizes an 
allowance for credit losses on its accounts receivable 
in accordance with ASU 2016-13, which is based on the 
credit losses expected to arise over the life of the asset 
and is based on Current Expected Credit Loss (“CECL”). 
Prompt-pay discounts are offered to some customers; 
however, due to the uncertainty of the customers 
taking the discounts, the discounts are recorded when 
they are taken.
	
At December 31, 2023, the Company recorded 
advance payments from two of its customers in the 
amount of $15,498, which was recorded as deferred 
revenue on the balance sheet. The related performance 
obligations associated with these payments were 
satisfied in the first quarter of 2024. No such advanced 
payments existed at December 31, 2024.
	
The Company has distribution agreements with 
certain distributors of its pharmaceutical products that 
entitle those distributors to distribution and services-
related fees. The Company records distribution fees, 
and estimates of distribution fees, as offsets to 
revenue.
	
Disaggregated net sales by product class are as 
follows:

The Company’s cosmetic ingredients are currently 
marketed worldwide by five distributors, of which the 
United States (“U.S.”)-based ASI purchases the largest 
volume. For the years ended December 31, 2024 and 
2023, approximately 16% and 21%, respectively, of 
the Company’s sales were to (a) its foreign-based 
distributors (which does not include ASI), which 
marketed and distributed the Company’s cosmetic 
ingredients to customers outside the U.S. and (b) a 
few foreign customers for the Company’s medical 
lubricants, which were sold directly to those customers 
by the Company.
	
Disaggregated sales by geographic region are as 
follows:

* Although a significant percentage of ASI’s 
purchases from the Company are sold to foreign 
customers, all sales to ASI are considered U.S. sales 
for financial reporting purposes, since all shipments 
to ASI are shipped to ASI’s warehouses in the U.S. A 
certain percentage of those products are subsequently 
shipped by ASI to its foreign customers. Based on 
sales information provided to the Company by ASI, 
79% of ASI’s sales in 2024 were to customers in foreign 
countries, compared with 69% in 2023. ASI’s largest 
foreign market in both 2024 and 2023 was China, 
which accounted for approximately 43% of ASI’s sales 
in 2024 and 29% of sales in 2023. 
Cash and Cash Equivalents
	
For financial statement purposes, the Company 
considers as cash equivalents all highly liquid 
investments with an original maturity of three months 
or less at the time of purchase. The Company deposits 
cash and cash equivalents with financially strong, 
FDIC-insured financial institutions, and it believes that 
any amounts above FDIC insurance limitations are 
at minimal risk. The amounts held in excess of FDIC 
limits at any point in time are considered temporary 
and are primarily due to the timing of maturities of 
United States Treasury Bills and Certificates of Deposit. 
Cash and cash equivalents held in these accounts are 
currently insured by the Federal Deposit Insurance 
Corporation (“FDIC”) up to a maximum of $250,000. At 
December 31, 2024 and 2023, approximately $234,000 
and $311,000 respectively, exceeded the FDIC limit. 
The Company also invests in certain money market 
mutual funds that are protected as securities by the 
Securities Investor Protection Corporation (“SIPC”). At 
December 31, 2024, cash held in these money market 
mutual funds of approximately $563,000 exceeded the 
SIPC limit. At December 31, 2023, cash held in these 
money market mutual funds was below the SIPC limit.

Dividends
	
On July 10, 2024, the Company’s Board of Directors 
declared a cash dividend of $0.35 per share, which 
was paid on July 31, 2024, to all holders of record as of 
July 23, 2024. Dividends totaling $1,607,855 were paid 
and the balance of $156 is payable to stockholders 
whose old Guardian Chemical shares have not yet 
been exchanged to United-Guardian, Inc. shares and 
are pending escheatment. On January 30, 2024, the 
Company’s Board of Directors declared a cash dividend 
of $0.25 per share, which was paid on February 20, 
2024, to all holders of record as of February 12, 2024. 
Dividends totaling $1,148,468 were paid. The balance 
of $112 is payable to stockholders whose old Guardian 
Chemical shares have not yet been exchanged 
to United-Guardian, Inc. shares and are pending 
escheatment. On January 27, 2025, the Company’s 
Board of Directors declared a cash dividend of $0.35 
per share, which was paid on February 18, 2025, 
to all stockholders of record as of February 10, 2025.
 	
On July 12, 2023, the Company’s Board of 
Directors declared a cash dividend of $0.10 per share, 
which was paid on August 2, 2023, to all stockholders 
of record as of July 26, 2023. The Company did not 
declare any other dividends in 2023. During 2023, 
the Company declared total dividends of $459,432, 
of which $459,387 was paid. The balance of $45 
is payable to stockholders whose old Guardian 
Chemical shares have not yet been exchanged to 
United-Guardian, Inc. shares and are pending 
escheatment. In June of 2023, the Company’s Board 
of Directors changed the Company’s dividend 
declaration practice and expects to consider a 
semi-annual dividend declaration in January and 
July of each year.
Marketable Securities 
	
The Company’s marketable securities include 
investments in equity mutual funds, United States 
Treasury Bills (“U.S. Treasury Bills”) and Certificates 
of Deposit with maturities longer than 3 months. The 
Company’s marketable equity securities are reported 
at fair value with the related unrealized and realized 
gains and losses included in net income. U.S Treasury 
Bills and Certificates of Deposit are recorded at 
amortized cost. Realized gains or losses on mutual 
funds are determined on a specific identification basis. 
The Company evaluates its investments periodically 
for possible other-than-temporary impairment by 
reviewing factors such as the length of time and extent 
to which fair value had been below cost basis, the 
financial condition of the issuer and the Company’s 
ability and intent to hold the investment for a period of 
time which may be sufficient for anticipated recovery 
of market value. The Company would record an 
impairment charge to the extent that the cost of the 
available-for-sale securities exceeds the estimated 
fair value of the securities and the decline in value is 
determined to be other-than-temporary. During 2024 
and 2023, the Company did not record an impairment 
charge regarding its investment in marketable 
securities because management believes, based on 
its evaluation of the circumstances, that the decline in 
fair value below the cost of certain of the Company’s 
marketable securities is temporary.
Inventories
	
Inventories are valued at the lower of cost and 
net realizable value. Net realizable value is equal 
to the selling price less the estimated costs of selling 
and/or disposing of the product. Cost is determined 
using the average cost method, which approximates 
cost determined by the first-in, first-out (“FIFO”) 
method. Inventory costs include material, labor and 
factory overhead.

United-Guardian, Inc. Annual Report 2023 13
Property, Plant and Equipment
	
Property, plant and equipment are carried at cost, 
less accumulated depreciation. Major replacements and 
betterments are capitalized, while routine maintenance 
and repairs are expensed as incurred. Assets are 
depreciated under both accelerated and straight-line 
methods. Depreciation charged as a result of using 
accelerated methods was not materially different 
than that which would result from using the straight-
line method for all periods presented. Certain factory 
equipment and fixtures are constructed by the Company 
using purchased materials and in-house labor. Such 
assets are capitalized and depreciated on a basis 
consistent with the Company’s purchased fixed assets.
	
Estimated useful lives are as follows: 
Factory equipment and fixtures  	
5 - 7 years  
Building		
	
	
40 years  
Building improvements	
Lesser of useful life 	
	
	
	
	
	
or 20 years  
Impairment of Long-Lived Assets
	
Long-lived assets are reviewed for impairment 
whenever events or changes in circumstances 
indicate that the carrying amount of an asset may 
not be recoverable. The recoverability of assets to be 
held and used is measured by a comparison of the 
carrying amount of an asset to future net cash flows 
expected to be generated by the asset. If such assets 
are considered to be impaired, the impairment to be 
recognized is measured by the amount by which the 
carrying amount of the assets exceeds the fair value of 
the assets. Assets to be disposed of are reported at the 
lower of the carrying amount or fair value less costs to 
sell. No impairments were necessary at December 31, 
2024 and 2023.
Fair Value of Financial Instruments
	
Management of the Company believes that the 
fair value of financial instruments, consisting of cash 
and cash equivalents, accounts receivable, accounts 
payable, and accrued expenses, approximates their 
carrying value due to their short payment terms and 
liquid nature.
Concentration of Credit Risk
 	
Accounts receivable potentially expose the 
Company to concentrations of credit risk. The 
Company monitors the amount of credit it allows 
each of its customers, using the customer’s prior 
payment history to determine how much credit to 
allow or whether credit should be given at all. It is 
the Company’s policy to discontinue shipments to 
any customer that is substantially past due on its 
payments. The Company sometimes requires payment 
in advance from customers whose payment record 
is questionable. As a result of its monitoring of the 
outstanding credit allowed for each customer, as well 
as the fact that the majority of the Company’s sales are 
to customers whose satisfactory credit and payment 
record has been established over a long period of time, 
the Company believes that its accounts receivable 
credit risk has been reduced.
	
For the year ended December 31, 2024, four of the 
Company’s pharmaceutical wholesalers and cosmetic 
ingredient distributors accounted for approximately 
80% of the Company’s gross sales during the year 
and approximately 87% of its outstanding accounts 
receivable on December 31, 2024. For the year ended 
December 31, 2023, the same four pharmaceutical 
wholesalers and cosmetic ingredient distributors 
accounted for a total of approximately 77% of the 
Company’s gross sales during the year and 89% of its 
outstanding accounts receivable on December 31, 2023.
Supplier Concentration 
	
Most of the principal raw materials used by the 
Company consist of common industrial organic and 
inorganic chemicals and are available in ample supply 
from numerous sources. However, there are some raw 
materials used by the Company that are not readily 
available or require longer lead times. The Company 
has three major raw material vendors that collectively 
accounted for approximately 83% and 76% of the raw 
material purchases by the Company in 2024 and 2023, 
respectively. In addition to the Company’s raw materials 
concentration, the Company utilizes one contract 
manufacturer for the production of its pharmaceutical 
product, Renacidin. Any disruption in this manufacturer’s 
operations could have a material impact on the 
Company’s revenue stream.

14  United-Guardian, Inc. Annual Report 2024
Income Taxes
	
Income taxes are accounted for under the asset 
and liability method. Deferred tax assets and liabilities 
are recognized for future tax consequences attributable 
to the temporary differences between the financial 
statement carrying amounts of assets and liabilities and 
their respective tax bases and operating loss and tax 
credit carry forwards. Deferred tax assets and liabilities 
are measured using enacted tax rates expected to 
apply in the years in which those temporary differences 
are expected to be recovered or settled. The effect on 
deferred tax assets and liabilities of a change in tax rates 
is recognized in the period that includes the enactment 
date. Deferred tax assets are reduced by a valuation 
allowance when, in the opinion of management, it is 
more likely than not that some portion or all the deferred 
tax assets will not be realized.
 	
Uncertain tax positions are accounted for utilizing 
a recognition threshold and measurement attribute for 
financial statement recognition and measurement of a 
tax position taken or expected to be taken in a tax return. 
As of December 31, 2024 and 2023, the Company did 
not have any unrecognized income tax benefits. It is the 
Company’s policy to recognize interest and penalties 
related to taxes as interest expense as incurred. During 
the years ended December 31, 2024 and 2023, the 
Company did not record any tax-related interest or 
penalties. The Company’s tax returns for 2021 and all 
subsequent years are subject to examination by the 
United States Internal Revenue Service (“IRS) and by the 
State of New York.
Research and Development 
	
Research and development expenses are 
expenditures incurred in connection with in-house 
research on new and existing products. It includes 
payroll and payroll related expenses, outside laboratory 
expenditures, lab supplies, equipment repairs and 
maintenance and equipment depreciation.
Advertising Expenses
	
Advertising costs are expensed as incurred. The 
Company did not incur any advertising costs for the 
years ended December 31, 2024 or 2023.
Earnings Per Share Information
	
Basic earnings per share are computed by dividing 
net income by the weighted average number of 
common shares outstanding during the year. Diluted 
earnings per share would include the dilutive effect of 
outstanding stock options, if any.
New Accounting Standards
	
On November 4, 2024, the FASB issued ASU 
2024-03 “Disaggregation of Income Statement 
Expenses” (“DISE”). This guidance requires disaggregation 
of certain expense captions into specified categories 
in disclosures within the footnotes to the financial 
statements. Subsequently issued ASU 2025-01, 
clarified the effective date of this standard. This 
guidance is effective for annual reporting periods 
beginning after December 15, 2026, and for interim 
periods, within annual reporting periods beginning after 
December 15, 2027.
	
In December 2023, the FASB issued ASU 2023-09 
“Income Taxes—Improvements to Income Tax 
Disclosures”. This guidance enhances the transparency 
and decision usefulness of income tax disclosures. 
More specifically, the amendments relate to the 
income tax rate reconciliation and income taxes paid 
disclosures and require 1) consistent categories and 
greater disaggregation of information in the rate 
reconciliation and 2) income taxes paid disaggregated 
by jurisdiction. This guidance is effective for fiscal 
years beginning after December 31, 2024.
 	
In November 2023, the FASB issued ASU 2023-07, 
“Improvements to Reportable Segment Disclosures”. 
This amendment requires additional disclosures by 
public entities, including those with a single reportable 
segment, to disclose significant segment expenses 
and other segment items for each reportable segment. 
The guidance applies to fiscal years beginning after 
December 15, 2023, and interim periods within fiscal

CASH AND CASH EQUIVALENTS
	
Cash and cash equivalents include currency 
on hand, demand deposits with banks or financial 
institutions, and short-term, highly liquid investments 
that are both readily convertible to known amounts 
of cash and so near their maturity that they present 
minimal risk of changes in value because of changes 
in interest rates. The following table summarizes the 
Company’s cash and cash equivalents:

MARKETABLE SECURITIES
	
Marketable securities include investments in equity 
mutual funds, which are reported at their fair values,  
and U.S. Treasury Bills and Certificates of Deposit with 
original maturities greater than 3 months, which are 
recorded at amortized cost.
	
The disaggregated net gains and losses on 
the marketable securities recognized in the income 
statement for the years ended December 31, 2024 
and 2023 are as follows:

The fair values of the Company’s marketable 
securities are determined in accordance with US GAAP, 
with fair value being defined as the amount that would 
be received to sell an asset or paid to transfer a liability 
in an orderly transaction between market participants 
at the measurement date. As such, fair value is a 
market-based measurement that should be determined 
based on assumptions that market participants 
would use in pricing an asset or liability. As a basis for 
considering such assumptions, the Company utilizes 
the three-tier value hierarchy, as prescribed by US 
GAAP, which prioritizes the inputs used in measuring 
fair value as follows:
	
•  Level 1—inputs to the valuation methodology are 
quoted prices (unadjusted) for identical assets or 
liabilities in active markets.
	
•  Level 2—inputs to the valuation methodology 
include quoted prices for similar assets and 
liabilities in active markets, and inputs that are 
observable for the asset or liability, either directly 
or indirectly, for substantially the full term of the 
financial instrument.
	
•  Level 3—inputs to the valuation methodology 
are unobservable and significant to the fair value 
measurement.

16  United-Guardian, Inc. Annual Report 2024
	
The Company’s marketable equity securities, which are considered available-for-sale securities, are 
re-measured to fair value on a recurring basis and are valued using Level 1 inputs using quoted prices (unadjusted) 
for identical assets in active markets. The following tables summarize the Company’s investments:

Inventories are valued at the lower of cost and net realizable value. Net realizable value is equal to the selling 
price less the estimated costs of selling and/or disposing of the product. Cost is determined using the average 
cost method, which approximates cost determined by the first-in, first-out method. Finished product inventories on 
December 31, 2024 and December 31, 2023 are net of a reserve of $32,792 and $47,000, respectively.

BENEFIT PLANS
Defined Contribution Plan
	
The Company sponsors a 401(k) defined 
contribution plan (“DC Plan”) that provides for a dollar-
for-dollar employer matching contribution of the 
first 4% of each employee’s pay. Employees become 
fully vested in employer matching contributions 
immediately. Company 401(k) matching contributions 
were approximately $84,000 and $83,000 for the years 
ended December 31, 2024 and 2023, respectively.
	
The Company also makes discretionary 
contributions to each employee’s account based 
on a “pay-to-pay” safe-harbor formula that qualifies 
the 401(k) Plan under current IRS regulations. For 
the years ended December 31, 2024 and 2023, 
the Company’s Board of Directors authorized 
discretionary contributions in the amount of $115,000 
and $109,000, respectively, to be allocated among 
all eligible employees. Employees become vested 
in the discretionary contributions as follows: 20% 
after two years of employment, and 20% for each 
year of employment thereafter until the employee 
becomes fully vested after six years of employment. 
The discretionary contribution for 2024 was paid in 
February 2025 and is included in accrued expenses.
NOTE  G
GEOGRAPHIC and OTHER INFORMATION 
	
Through its Guardian Laboratories division, the 
Company conducts research, product development, 
manufacturing, and marketing of cosmetic ingredients, 
pharmaceuticals, medical lubricants and sexual 
wellness ingredients. Prior to July 1, 2023, the 
Company manufactured and reported sales of a line of 
specialty industrial products, however this produce line 
was discontinued after the second quarter of 2023 due 
to low sales volume with no growth. All the products 
that the Company markets, with the exception of 
Renacidin, are produced at its facility in Hauppauge, 
New York. Renacidin, a urological product, is 
manufactured for the Company by an outside contract 
manufacturer. The Company’s R&D department not 
only develops new products but also modifies and 
refines existing products, with the goal of expanding 
the potential markets for the Company’s products. 
Many of the cosmetic ingredients manufactured by 
the Company, particularly its Lubrajel line of water-
based moisturizing and lubricating gels, are currently 
used by many of the major multinational personal care 
products companies.
 	
The Company operates in one business segment. 
The Company’s products are separated into five 
distinct product categories: cosmetic ingredients, 
pharmaceuticals, medical lubricants, sexual wellness 
ingredients and industrial products. The Company 
discontinued its industrial line of products after 
the second quarter of 2023 due to a low volume 
of sales and no growth. Each product category is 
marketed differently.
	
The cosmetic ingredients are marketed through 
a global network of distributors. These distributors 
purchase products outright from the Company and 
provide the main marketing and sales functions for 
these products on behalf of the Company. They in 
turn receive their compensation for those efforts 
by re-selling those products at a markup to their 
customers. This enables the Company to aggressively 
have its products marketed without the high cost of 
maintaining its own in-house marketing and sales 
staff. In 2024 we hired a marketing director to work 
alongside our distributors and provide marketing 
materials, training and aid in customer visits. We 
believe this strategy will allow us to better serve our 
mutual customers and build stronger relationships 
with our distributors. The Company currently has one 
written distribution agreement with the companies 
that market its cosmetic ingredients. The marketing 
contract with ASI terminated on December 31, 2023, 
and the Company is currently in negotiations with ASI 
to establish a new marketing agreement. The Company 
is hopeful that it will have a new marketing agreement 
in place with ASI by mid-2025. The Company’s 
relationship with ASI continues to be strong, and during 
this period of renegotiation the Company continues 
to fill ASI’s orders on a timely basis. All sales of the 
Company’s cosmetic ingredients are final other than 
product later determined to be defective, and the 
Company does not make any sales on consignment.
 	
No prior regulatory approval is needed by 
the Company to sell any products other than its 
pharmaceutical products. The end users of its products 
may or may not need regulatory approvals, depending 
on the intended claims and uses of those products.

United-Guardian, Inc. Annual Report 2024  19
	
The pharmaceutical products include a urological 
product and a topical biocide that are sold to end users 
primarily through distribution agreements with major 
drug wholesalers. For these products, the Company 
does the marketing, and the drug wholesalers supply 
the product to the end users, such as hospitals and 
pharmacies. The Company’s marketing effort for 
Renacidin, its most important drug product, currently 
includes a Renacidin website which provides product 
information to patients and healthcare providers as 
well as a focus group study that was conducted in 
2024. There is currently no active marketing effort 
for Clorpactin. Both of these products were originally 
developed in the 1950s. Clorpactin pre-dated the need 
for a formal New Drug Application (“NDA”), and the 
current sterile liquid form of Renacidin is marketed 
under an NDA that was approved by the FDA in 1990.
	
The medical lubricants are not pharmaceutical 
products. They consist primarily of water-based 
lubricating gels, which are marketed by the Company 
directly to manufacturers that incorporate them 
into urologic catheters and other medical devices 
and products that they sell. These products are 
distinguished from pharmaceutical products in that, 
unlike the pharmaceutical products, the Company 
is not required to obtain regulatory approval prior 
to marketing them. Regulatory approvals are the 
responsibility of the companies that market the 
finished products in which the Company’s products are 
used, which are typically classified as medical devices. 
However, the Company is responsible for manufacturing 
these products in accordance with current Good 
Manufacturing Practices, and its manufacturing facility 
is subject to regular FDA oversight.
	
The industrial products were marketed by the 
Company directly to manufacturers, and generally 
did not require that the Company obtain regulatory 
approval. However, the manufacturers of the finished 
products may have to obtain such regulatory approvals 
before marketing these products. The Company 
discontinued this product line on July 1, 2023.         
	
The sexual wellness ingredients are marketed 
by Brenntag Specialties, a global market leader in 
chemicals and ingredient distribution. The Company 
entered into a marketing and distribution agreement 
with Brenntag in October of 2023 in the United States, 
Canada, Mexico, Central America and South America.
 
	
The following tables present the significant 
concentrations of the Company’s sales. Although a 
significant percentage of Customer A’s purchases 
from the Company are sold to foreign customers, in 
table “(b)” below all sales to Customer A are included 
in the “United States” sales numbers because all 
shipments to Customer A are delivered to Customer A’s 
warehouses in the U.S.
	
In addition, there are four customers for the 
Company’s medical lubricants that take delivery of their 
shipments in the U.S. but potentially ship some of that 
product to manufacturing facilities outside the U.S. 
Since the Company makes those shipments to U.S. 
locations, sales to those customers are also included 
in the “United States” sales number in the table below.

SUPPLEMENTAL DISCLOSURES OF CASH FLOW 
INFORMATION AND NON-CASH INVESTING AND 
FINANCING ACTIVITIES
	
As of December 31, 2024, the Company had 
a number of unconverted Guardian Chemical 
shares that would convert to approximately 447 
shares of United-Guardian, Inc. common stock if all 
of the remaining holders of those Guardian shares 
converted their Guardian stock to United-Guardian 
stock. The Company’s transfer agent continues to try 
to locate the holders of those shares in anticipation 
of escheating them to the appropriate state 
jurisdictions. The Company is currently accruing

United-Guardian, Inc. Annual Report 2024  21
EXECUTIVE LEVEL OVERVIEW
	
We specialize in manufacturing cosmetic 
ingredients, pharmaceuticals, medical lubricants, and 
sexual wellness ingredients through our Guardian 
Laboratories division. With a long-standing reputation 
for delivering high-quality specialty products, we are 
committed to serving diverse markets with innovative 
solutions.
	
As part of our strategic focus, we discontinued our 
specialty industrial products line in mid-2023 due to low 
sales and limited growth potential. This shift allows us 
to concentrate on higher-value product categories with 
greater market opportunities.
	
In October 2023, we took a significant step toward 
expanding our presence in the sexual wellness market 
by partnering with Brenntag Specialties, a global leader 
in chemicals and ingredients distribution. Under this 
agreement, Brenntag will distribute our new Natrajel line 
of sexual wellness ingredients across North and South 
America. While we reported no sales of this product line 
in 2024, we anticipate beginning manufacturing and 
revenue generation in 2025.
	
With a refined product portfolio and strategic 
partnerships, we are well-positioned for future growth, 
leveraging our expertise in specialty ingredients to 
capitalize on emerging market opportunities.
IMPACT OF GLOBAL SUPPLY CHAIN INSTABILITY, 
INFLATION AND TARIFFS
	
The continued supply chain instability, primarily 
caused by military tensions in the Middle East, continues 
to impact vessels’ access to the Red Sea and Suez 
Canal. Shipping experts say this crisis may last into the 
first half of 2025. We continue to work with our suppliers 
regarding lead times and continue to closely monitor 
this situation. Although we have not yet experienced 
any delays in receiving raw materials or an increase in 
shipping costs, we are aware that the situation is fluid 
and could impact us at any time. If that occurs, we may 
experience longer lead times and increased shipping 
costs for some of our raw materials, which may impact 
our future gross margins. As a result of this global 
supply chain instability, there continues to be uncertainty 
regarding the potential impact on our operations 
or financial results and we are unable to provide an 
accurate estimate or projection as to what the future 
impact will be.
	
The Trump administration has communicated its 
intention to impose tariffs on many products imported 
from China, Canada and Mexico. Some of those tariffs 
went into effect on March 4, 2025. Since that time the 
Trump administration has increased some of those 
tariffs and postponed others. It has threatened to 
levy tariffs on additional countries, including those of 
the European Union. Many of the countries on which 
those tariffs have been levied have imposed their own 
retaliatory tariffs or threated to impose tariffs on goods 
they import from the U.S. The tariff situation remains 
fluid and is subject to modification at any time. At this 
time, it is difficult to determine the impact of these 
tariffs on our business. We will continue to monitor this 
situation closely.
	
While we obtain most of our raw materials and 
lab supplies from domestic sources, we have three 
suppliers that obtain their raw materials from China. 
These materials are not purchased by us in large 
quantities, and we have adequate stock on hand to 
cover the next six months. In addition, we have one 
direct raw material supplier in China; however, the raw 
materials we purchase from this supplier are not in 
large quantities and the effect of this tariff would not 
materially impact the pricing of our products.
	
Many of our products are used in the formulation 
of finished products that are manufactured in China 
and then imported back into the United States (“U.S.”) 
for sale. There is the possibility that the tariffs levied on 
these finished products could result in an increase in 
their price, which could potentially impact demand for 
these products in the U.S.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
AND RESULTS OF OPERATIONS

22  United-Guardian, Inc. Annual Report 2024
	
Due to the continued uncertainty of this, any other 
tariffs that may be imposed, there continues to be 
uncertainty regarding the future impact of any additional 
tariffs on our operations or financial results.
CRITICAL ACCOUNTING POLICIES
	
Our financial statements have been prepared 
in accordance with Generally Accepted Accounting 
Principles in the United States of America (“US 
GAAP”). Preparation of financial statements requires 
us to make estimates and assumptions affecting the 
reported amounts of assets, liabilities, revenues, and 
expenses and the disclosure of contingent assets and 
liabilities. We use our historical experience and other 
relevant factors when developing our estimates and 
assumptions, which are continually evaluated. Note A, 
Nature of Business and Summary of Significant 
Accounting Policies, of the Notes to Financial 
Statements, included in Item 8, Financial Statements 
and Supplementary Data, of this Annual Report, includes 
a discussion of our significant accounting policies. The 
following accounting policies are those that we consider 
critical to an understanding of the financial statements 
because their application places the most significant 
demands on management’s judgment. Our financial 
results might have been different if other assumptions 
had been used or other conditions had prevailed.
Marketable Securities 
	
Our marketable securities include investments 
in equity mutual funds, Certificates of Deposit and 
U.S. Treasury Bills with original maturities of greater 
than three months. Our marketable equity securities 
are reported at fair value with the related unrealized 
and realized gains and losses included in net income. 
Certificates of Deposit and U.S. Treasury Bills with 
original maturities of more than 3 months are recorded 
at amortized cost. Realized gains or losses on mutual 
funds are determined on a specific identification basis. 
We evaluate our investments periodically for possible 
other-than-temporary impairment by reviewing factors 
such as the length of time and extent to which fair 
value had been below cost basis, the financial condition 
of the issuer, and our ability and intent to hold the 
investment for a period of time which may be sufficient 



for anticipated recovery of market value. We record 
an impairment charge to the extent that the cost of 
the available-for-sale securities exceeds the estimated 
fair value of the securities and the decline in value is 
determined to be other-than-temporary. During 2024 and 
2023, we did not record an impairment charge regarding 
our investment in marketable securities because 
management believes, based on an evaluation of the 
circumstances, that any decline in fair value below the 
cost of certain of our marketable securities is temporary.
Revenue Recognition
	
We record revenue in accordance with ASC Topic 
606 “Revenue from Contracts with Customers.” Under 
this guidance, revenue is recognized when a customer 
obtains control of promised goods or services, in an 
amount that reflects the consideration expected to be 
received in exchange for those goods or services. Our 
principal source of revenue is product sales.
	
Our sales, as reported, are subject to a variety 
of deductions, some of which are estimated. These 
deductions are recorded in the same period in which 
the revenue is recognized. Such deductions, primarily 
related to the sale of our pharmaceutical products, 
include chargebacks from the United States Department 
of Veterans Affairs (“VA”), rebates in connection with our 
current participation in Medicare programs, distribution 
fees, discounts, and outdated product returns.
These deductions represent estimates of the related 
obligations and, as such, knowledge and judgment are 
required when estimating the impact of these revenue 
deductions on sales for a reporting period.
 	
During 2024 and 2023, we participated in various 
government drug rebate programs related to the sale 
of Renacidin, our most important pharmaceutical 
product. These programs include the Veterans Affairs 
Federal Supply Schedule (“FSS”), and the Medicare 
Part D Coverage Gap Discount Program (“CGDP”). These 
programs require us to sell our products at a discounted 
price, typically in the form of a rebate. Our sales, as 
reported, are net of these rebates, some of which are 
estimated and are recorded in the same period that the 
revenue is recognized.
 	
On January 1, 2025, the Centers for Medicare & 
Medicaid Services (“CMS”) implemented a new 
Medicare Part D Manufacturer Discount Program 
(“Discount Program”), which replaced the prior CGDP. 
The new Discount Program eliminates the coverage 

United-Guardian, Inc. Annual Report 2024  23
gap benefit phase, introduces pharmaceutical 
manufacturer discounts in the initial and catastrophic 
coverage phases, and lowers the cap on enrollee out-
of-pocket costs. Under the new Discount Program, 
additional rebates are expected to be owed by 
pharmaceutical manufacturers due to the restructuring 
of the benefit periods and removal of the cap that was 
in place that limited the drug manufacturer’s liability. 
The overall financial impact of this new program will 
vary depending on the products being reimbursed but 
it is expected to increase Medicare Part D rebates for 
drug manufacturers.
 	
On January 31, 2024, we were notified by CMS 
that we qualified as a “specified small manufacturer” 
and would be entitled to a multi-year phase-in period 
during which we would pay a lower percentage discount 
on drugs dispensed to beneficiaries. Based on our 
“specified small manufacturer” designation, it appears, 
based on our current level of sales through the Medicare 
Part D Program, we would have reduced rebate 
liabilities in years 2025 and 2026, with rebates gradually 
increasing each year after, until they reach their full 
phase-in by 2031. By the end of the phase in period in 
2031, these rebate liabilities are expected to significantly 
exceed the liabilities we have recorded under the CGDP 
in previous years.
 	
As long as a valid purchase order has been 
received and future collection of the sale amount 
is reasonably assured, we recognize revenue from 
sales of our products when those products are 
shipped, which is when our performance obligation 
is satisfied. Our cosmetic products are shipped EXW 
from our facility in Hauppauge, NY, and the risk of 
loss and responsibility for the shipment passes to 
the customer upon shipment. Sales of our medical 
lubricant products are deemed final upon shipment, 
and we have no obligation to repurchase or allow 
the return of these goods unless they are defective. 
Sales of our pharmaceutical products are final upon 
shipment unless (a) they are found to be defective; (b) 
the product is damaged in shipping; (c) the product is 
too close to its expiration date for the customer to sell; 
or (d) the product is expired but is not more than one 
year after its expiration date. These return policies are 
in conformance with standard pharmaceutical industry 
practice. We estimate an allowance for outdated 
material returns based on previous years’ historical 
returns of our pharmaceutical products.

	
We do not make sales on consignment, and the 
collection of the proceeds of the sale of any of our 
products is not contingent upon the customer being 
able to sell the goods to a third party.
	
Any allowances for returns are taken as a reduction 
of sales within the same period the revenue is 
recognized. Such allowances are determined based on 
historical experience under ASC Topic 606-10-32-8. We 
have not experienced significant fluctuations between 
estimated allowances and actual activity.
	
We have distribution agreements with certain 
distributors of our pharmaceutical products that entitle 
those distributors to distribution and services-related 
fees. We record distribution fees, and estimates of 
distribution fees, as offsets to revenue.
 
Accounting for Financial Instruments—Credit Losses
	
We recognize an allowance for our trade receivables 
to present the net amount expected to be collected 
as of the balance sheet date. This allowance is based 
on the credit losses expected to arise over the life 
of the asset and are based on Current Expected Credit 
Losses (CECL).
	
We perform ongoing credit evaluations of our 
customers and adjust credit limits, as determined by a 
review of current credit information. We continuously 
monitor collection and payments from customers and 
maintain an allowance for credit losses based upon 
historical experience, anticipation of uncollectible 
accounts receivable and any specific customer 
collection issues that have been identified. While our 
credit losses have historically been low and within 
expectations, we may not experience the same credit 
loss rates that have historically been attained in the 
future. The receivables are highly concentrated in a 
relatively small number of customers. Therefore, a 
significant change in the liquidity, financial position, 
or willingness to pay timely, or at all, of any one of our 
significant customers would have a significant impact 
on our results of operations and cash flows. When 
determining the reserve for credit losses, we take into 
consideration current and future economic conditions 
and the impact that these changing dynamics may 
have on potential future losses.

24  United-Guardian, Inc. Annual Report 2024
	
The timing between recognition of revenue 
for product sales and the receipt of payment is 
not significant. Our standard credit terms, which 
vary depending on the customer, range between 
30 and 60 days. We provide an allowance for credit 
losses related to our accounts receivable for which 
collection is doubtful in accordance with ASU 2016-13. 
In accordance with FASB ASC Topic 326, “Financial 
Instruments—Credit Losses (Topic 326): Measurement 
of Credit Losses on Financial Instruments”, (“ASC 326”), 
we present financial assets at the net amount expected 
to be collected, requiring immediate recognition of 
estimated credit losses expected to occur over the 
asset’s remaining life.
	
As of December 31, 2024 and December 31, 2023, 
the allowance for credit losses on accounts receivable 
was $14,342 and $16,672, respectively. Prompt-pay 
discounts are offered to some customers; however, due 
to the uncertainty of the customers taking the discounts, 
the discounts are recorded when they are taken.
Inventory Valuation Allowance
	
In conjunction with our ongoing analysis of 
inventory valuation, management constantly monitors 
projected demand on a product-by-product basis. 
Based on these projections, management evaluates 
the levels of write-downs required for inventory 
on hand and inventory on order from contract 
manufacturers. Although we believe that we have been 
reasonably successful in identifying write-downs in 
a timely manner, sudden changes in buying patterns 
from customers, either due to a shift in product 
interest and/or a complete pullback from their 
expected order levels, may result in the recognition of 
larger-than-anticipated write-downs. We have performed 
an evaluation of our inventory on hand as of 
December 31, 2024 and December 31, 2023, and 
believe the reserves are adequate to cover any slow-
moving or obsolete inventory.
RESULTS OF OPERATIONS
Sales
	
Sales increased by approximately 12%, from 
$10,885,154 in 2023 to $12,181,971 in 2024. The increase 
in sales was primarily due to an increase in sales of our 
cosmetic ingredient products, specifically an increase 
of 51% in sales to our largest distributor, ASI, in 2024 
compared with 2023. In addition, sales of our medical 
lubricants increased by 16%, primarily due to increased 
orders placed by our largest customer in China.
	
Cosmetic Ingredients
	
	
Sales of our cosmetic ingredients increased 
by approximately 32%, from $4,132,334 in 2023 
to $5,438,262 in 2024. The increase was primarily 
due to an increase in sales to ASI. Based on 
information provided to the Company by ASI, the 
reasons for the increase during 2024 was due to 
increased demand for our products in China due 
to regaining market share at certain key accounts. 
This increase was offset by sales to our other 
four distributors, whose sales decreased by a net 
of approximately 49%, while sales from two of 
our small direct cosmetic ingredient customers 
increased by approximately 19%. This decrease 
was primarily due to reformulations.
	
We continue to experience global competition 
from Asian and European companies that 
manufacture and sell products that are competitive 
with our products. These competitive products 
are usually sold at a lower price than our products; 
however, they may not compare favorably to the 
level of performance and quality of our products. 
We work closely with our network of distributors 
to price our products as competitively as possible 
and, when appropriate, to offer additional volume 
discounts and more aggressive pricing to maintain 
and increase sales and expand our customer 
base. We expect that this competitive environment 
will continue in 2025 and we plan to enhance 
our competitive position by strengthening our 
core capabilities and investing in new products, 
especially in the area of naturally derived products. 
We will continue to provide high-quality products, 
technical expertise, and the reliability our 
customers have come to expect from us.
	

United-Guardian, Inc. Annual Report 2024  25
	
Pharmaceuticals
	
	
Because there are fees, rebates, and 
allowances associated with sales of our two 
pharmaceutical products, Renacidin and 
Clorpactin®, discussion of our pharmaceutical 
sales includes references to both gross sales 
(before fees, rebates and allowances) and net 
sales (after fees, rebates and allowances). Gross 
sales of our two pharmaceutical products, 
Renacidin and Clorpactin, together decreased 
by approximately 5%, from $5,894,220 in 2023 
to $5,602,259 in 2024. Gross sales of Renacidin 
decreased by approximately 4%, from $5,127,069 
in 2023 to $4,897,331 in 2024, and gross sales of 
Clorpactin decreased by 8% from $767,151 in 2023 
to $704,928 in 2024.
	
The primary reason for the decrease 
in Renacidin sales was due to our contract 
manufacturer temporarily ceasing manufacturing 
during the latter part of 2023 and the beginning 
of 2024. During this time, we were unable to fill 
complete orders of Renacidin and were allocating 
product to all of our pharmaceutical distributors. 
We resumed filling orders in full towards the end of 
March 2024.
	
Net sales of our pharmaceutical products 
decreased by approximately 5% in 2024 compared 
with the same period in 2023. The decrease in 
net sales was due to a decrease in gross sales 
combined with a commensurate decrease in 
certain pharmaceutical-related rebates and 
allowances. The decrease in pharmaceutical-
related rebates and allowances in 2024 was 
primarily due to a decrease in VA Chargebacks 
and Medicare rebates.
	
Medical Lubricants
	
	
Sales of our medical lubricants increased by 
approximately 16% in 2024, from $1,750,632 in 2023 
to $2,028,564 in 2024. The increase in sales was 
driven by increased demand from one of our larger 
contract manufacturer customers located in China.
	
	
Sexual Wellness Ingredients
	
	
There were no sales of our sexual wellness 
ingredients in 2024, since we only began our 
marketing efforts for those products in mid-2023. 
Customers need to qualify new ingredients and 
perform product development testing prior to 
launching a new product. It is not unusual for this 
process to take a year or more and inherently it 
will require additional time for new ingredients to 
generate sales. Our distributor for these products 
has informed us of the possibility of orders being 
placed in mid-2025.
	
Industrial Products
	
	
There were no sales of our industrial products 
during 2024 due to this product line being 
discontinued after the second quarter of 2023.
Gross Profit on Sales
	
Gross profit on sales was 53% in 2024 compared 
with 50% in 2023. The increase in gross profit was 
primarily due to two factors. The first was an increase 
in sales of our cosmetic ingredients of 32% in 2024 
compared to 2023, which carry a higher profit margin 
than our pharmaceutical products, combined with the 
fact that in 2024, the percentage of cosmetic product 
sales as a percentage of total sales increased to 
approximately 45%, compared with 38% in 2023. The 
second factor was lower per unit overhead costs due 
to increased production, which was caused by higher 
demand for some of our products.
Operating Expenses
	
Operating expenses increased by approximately 
13%, from $2,078,564 in 2023 to $2,356,819 in 2024. 
The increase was mainly attributable to the following: 
1) increases in sales and marketing expenses incurred in 
connection with the hiring of our new Marketing Director; 
2) an increase in payroll and payroll-related expenses; 
and 3) an increase in fees paid to our Board of Directors. 
In connection with our growth initiatives, we anticipate 
that operating expenses will increase modestly in 2025. 

26  United-Guardian, Inc. Annual Report 2024
Research and Development Expenses 
	
Research and development expenses decreased by 
approximately 2%, from $463,992 in 2023 to $456,779 
in 2024. In connection with the Company’s growth 
initiatives, we expect our research and development 
expenses to increase modestly during 2025.
Investment Income 
	
Investment income increased by approximately 
42%, from $306,651 in 2023 to $434,679 in 2024. 
The increase was primarily due to an increase in 
interest income from investments in longer term U.S. 
Treasury Bills and Certificates of Deposit in 2024 
compared to 2023. In addition, during 2024 we held 
more funds in money market accounts which yielded 
higher interest income compared to 2023. During the 
second half of 2023, we repositioned our marketable 
securities portfolio, liquidating most of our equity 
and fixed income mutual funds. The proceeds from 
these sales were used to purchase U.S. Treasury Bills 
and Certificates of Deposit to take advantage of the 
increase in interest rates.
Net Gain on Marketable Securities
	
For the year ended December 31, 2024, we recorded 
net gains on our marketable securities portfolio of 
$26,989 compared with net gains of $81,095 in 2023. 
We repositioned our marketable securities portfolio 
in the second half of 2023 to take advantage of the 
increase in interest rates. Management, as well as 
the Investment Committee of the Board of Directors, 
continue to closely monitor our investment portfolio 
and will make any adjustments they believe may be 
necessary or appropriate in order to minimize the future 
impact on our financial performance due to volatility of 
the global financial markets.
 Provision for Income Taxes 
	
The provision for income taxes increased from 
$669,408 in 2023 to $857,582 in 2024. This increase 
was due to an increase in income before taxes. Our 
effective income tax rate was 20.9% in 2024 and 20.6% 
in 2023.
Liquidity and Capital Resources
	
Working capital increased from $10,718,457 at 
December 31, 2023 to $10,751,082 at December 31, 
2024. The increase in working capital was mainly due 
to an increase in cash and cash equivalents, marketable 
securities and inventories. The current ratio decreased 
from 8.0 to 1 at December 31, 2023 to 6.6 to 1 at 
December 31, 2024. The decrease in the current ratio 
was due mainly due to an increase in accounts payable.
 	
Accounts receivable (net of allowance for 
credit losses) as of December 31, 2024 decreased 
from $1,566,839 in 2023 to $1,428,455 in 2024. 
The decrease in accounts receivable was due to a 
decrease in sales during the fourth quarter of 2024. 
The receivables turnover, or “Days Sales Outstanding,” 
for 2024, was 45 days, compared with 50 days in 
2023. The allowance for credit losses on accounts 
receivable decreased from $16,672 in 2023 to $14,342 
in 2024, and we believe that the net balance of our 
accounts receivable as of December 31, 2024 was, and 
continues to be, fully collectible.
 	
We generated cash from operations of $3,466,251 
in 2024 compared with $3,144,480 in 2023. The 
increase in 2024 was primarily due to an increase in 
net income, offset by increases in inventories and 
deferred income taxes.
 	
Net cash used in investing activities was $7,077,395 
for the year ended December 31, 2024, compared with 
net cash provided by investing activities of $4,277,577 
for the year ended December 31, 2023. The shift 
was primarily due to an increase in the purchase of 
longer-term investments in 2024 that are classified 
as marketable securities. During 2023, most of our 
marketable securities consisted of U.S. Treasury Bills 
and Certificates of Deposit that had maturities of less 
than three months and were included in cash and cash 
equivalents. During 2024, we changed our investment 
strategy to longer term fixed income investments due to 
the anticipated decrease in interest rates.
 	
Net cash used in financing activities was 
$2,756,323 and $459,387 for the years ended 
December 31, 2024 and 2023, respectively. The 
increase was due to the payment of higher dividends 
in 2024 compared with 2023. During 2024, we paid 
dividends of $0.60 per share compared with $0.10 per 
share in 2023.
 	
We believe that our working capital is sufficient to 
support our operating requirements for the next fiscal 
year. Our long-term liquidity position will be dependent 
upon our ability to generate sufficient cash flow from 

United-Guardian, Inc. Annual Report 2024  27
profitable operations, and we expect to continue to 
use our cash to make dividend payments, purchase 
marketable securities, and to take advantage of growth 
opportunities that may arise that are in the best 
interest of the business and our stockholders.
 	
In connection with an upgrade to our building 
sprinkler system, costs of approximately $181,000 
have been incurred as of December 31, 2024. The 
project is substantially complete and is expected to be 
fully complete by the end of the first quarter of 2025, 
with additional planned expenditures of $14,000.
 	
During the fourth quarter of 2024, the Company 
replaced the roof on a portion of its facility in Hauppauge, 
New York at a cost of approximately $237,000.
 	
We have no off-balance-sheet transactions that 
have, or are reasonably likely to have, a current 
or future effect on our financial condition, changes 
in financial condition, revenues or expenses, results 
of operations, liquidity, capital expenditures or 
capital resources.

28  United-Guardian, Inc. Annual Report 2024
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Audit Committee and Stockholders of United-Guardian, Inc.:
Opinion on the Financial Statements
We have audited the accompanying balance sheet of United-Guardian, Inc. (the “Company”) as of December 31, 
2024 and 2023, and the related statements of income, stockholders’ equity, and cash flows for the year ended, and 
the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements 
present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, 
and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles 
generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an 
opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with 
the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with 
respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations 
of the Securities and Exchange Commission and the PCAOB.


We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan 
and perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to 
perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an 
understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the 
effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.	 	 	

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, 
whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included 
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit 
also included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable 
basis for our opinion.
Critical Audit Matters
Critical audit matters are matters arising from the current period audit of the financial statements that were 
communicated or required to be communicated to the audit committee and that (1) relate to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or 
complex judgments. We determined that there were no critical audit matters.
