Added
Additionally, as of December 31, 2025, we had 5 patent applications pending, including 5 U.S. applications and no applications in ex-U.S. jurisdictions. Patents provide some degree of protection for our intellectual property. However, the assertion of patent protection involves complex legal and factual determinations and is therefore uncertain.
Removed
As of December 31, 2024, there was indebtedness of $37.4 million outstanding under our term loan and senior revolving credit facility (collectively, the “Credit Agreement”). We were not in compliance with the consolidated net leverage ratio covenant contained in the Credit Agreement as of the December 31, 2024 test date.
Removed
On March 10, 2025, we entered into an amendment to the Credit Agreement (the “March 2025 Amendment”) pursuant to which the lenders and administrative agent agreed to waive such non-compliance, subject to the terms contained in the March 2025 Amendment.
Removed
The March 2025 Amendment provides, among other things, that our failure to achieve certain refinancing milestones, including receipt of a term sheet or commitment letter from one or more potential lenders, by the dates provided in the March 2025 Amendment or our failure to consummate a refinancing of the Credit Agreement by June 30, 2025, would, in either case, constitute an event of default under the Credit Agreement.
Removed
In such event, in addition to other actions our lenders may require, the amounts outstanding under the Credit Agreement may become immediately due and payable. See “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” of this report for additional information regarding the March 2025 Amendment.

We are exploring alternative sources of capital that would allow us to refinance our outstanding indebtedness by June 30, 2025, in order to avoid default under the Credit Agreement, but our ability to access such other sources of capital is uncertain.
Removed
There is no assurance that such capital will be available to us, be obtainable on commercially acceptable terms, or provide us with sufficient funds to meet our objectives.
Removed
Based on our anticipated cash flows from operations, unless we are able to access other sources of capital or extend the date for repayment under the Credit Agreement, we will be unable to pay our debt obligations and fund our operations for at least twelve months from the date of issuance of the consolidated financial statements contained in this Annual Report on Form 10-K.
Removed
As a result, there is substantial doubt about our ability to continue as a going concern. As discussed in Note 2 to the Consolidated Financial Statements included in “Part IV, Item 15.
Removed
Exhibits, Financial Statement Schedules” of this report, our consolidated financial statements include an explanatory paragraph that such financial statements were prepared assuming that we will continue as a going concern, continue our operations for the foreseeable future and realize assets and settle liabilities in the normal course of business.
Removed
The financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. Such adjustments could be material. Risks Related to Our Industry The life sciences industry is very competitive.

We expect that pharmaceutical and biotechnology companies and CROs will continue to be a significant source of our revenues for the foreseeable future, including in our CMT and Preclinical product families.
Removed
As a result, we are subject to risks and uncertainties that affect the pharmaceutical and biotechnology industries, such as government regulation, ongoing consolidation, uncertainty of technological change, and reductions and delays in research and development expenditures by companies in these industries. In particular, the biotechnology industry is largely dependent on raising capital to fund its operations.
Removed
If biotechnology companies that are our customers are unable to obtain the financing necessary to purchase our products, our business and results of operations could be materially and adversely affected.
Removed
In addition, we are dependent, both directly and indirectly, upon general health care spending patterns, particularly in the research and development budgets of the pharmaceutical and biotechnology industries, as well as upon the financial condition and purchasing patterns of various governments and government agencies.
Removed
As it relates to both the biotechnology and pharmaceutical industries, many companies have significant patents that have expired or are about to expire, which could result in reduced revenues for those companies.

Added
Item 1A. Risk Factors The following factors should be reviewed carefully, in conjunction with the other information contained in this Annual Report on Form 10-K. As previously discussed, our actual results could differ materially from the information included in our forward-looking statements. Our business faces a variety of risks.
Removed
You should carefully review all of these factors, as well as other risks described in our public filings, and you should be aware that there may be other factors, including factors of which we are not currently aware, that could cause these differences. Also, these forward-looking statements represent our estimates and assumptions only as of the date of this report.
Added
These risks include those described below and may include additional risks and uncertainties not presently known to us or that we currently deem immaterial.
Removed
We may not update these forward-looking statements, even though our situation may change in the future, unless we have obligations under the federal securities laws to update and disclose material developments related to previously disclosed information.

Added
If any of the events or circumstances described in the following risk factors occur or develop, our business operations, financial performance and financial condition could be materially and adversely affected, and the trading price of our common stock could decline.
Added
Risks Related to Our Industry The life sciences industry is very competitive, and many of our competitors have greater resources than we have. We expect to encounter increased competition from both established and development-stage companies that continually enter the market.
Added
These include companies developing and marketing life science instruments, systems and lab consumables, health care companies that manufacture laboratory-based tests and analyzers, diagnostic and pharmaceutical companies, analytical instrument companies, and companies developing life science or drug discovery technologies.
Added
Currently, our principal competition comes from established companies that provide products that perform many of the same functions for which we market our products. Many of our competitors have substantially greater financial, operational, marketing and technical resources than we do. Moreover, these competitors may offer broader product lines and tactical discounts and may have greater name recognition.
Added
In addition, we may face competition from new entrants into the field. We may not have the financial resources, technical expertise or marketing, distribution or support capabilities to compete successfully in the future.
Added
In addition, we face changing customer preferences and requirements, including increased customer demand for more environmentally friendly products. 6 Table of Contents The life sciences industry is also subject to rapid technological change and discovery. The development of new or improved products, processes or technologies by other companies may render our products or proposed products obsolete or less competitive.
Added
In some instances, our competitors may develop or market products that are more effective or commercially attractive than our current or future products. To meet the evolving needs of customers, we must continually enhance our current products and develop and introduce new products.
Added
However, we may experience difficulties that may delay or prevent the successful development, introduction and marketing of new products or product enhancements. In addition, our product lines are based on complex technologies that are subject to change as new technologies are developed and introduced in the marketplace.
Added
We may have difficulty in keeping abreast of the changes affecting each of the different markets we serve or intend to serve, and our new products may not be accepted by the marketplace or may generate lower than anticipated revenues.
Added
Our failure to develop and introduce products in a timely manner in response to changing technology, market demands, or the requirements of our customers could cause our product sales to decline, and we could experience significant losses.
Added
We offer, and plan to continue to offer, a broad range of products and have incurred, and expect to continue to incur, substantial expenses for the development of new products and enhancements to our existing products.
Added
The speed of technological change in our market may prevent us from being able to successfully market some or all of our products for the length of time required to recover development costs. Failure to recover the development costs of one or more products or product lines could decrease our profitability or cause us to experience significant losses.
Added
A portion of our revenues is derived from customers in the pharmaceutical and biotechnology industries and is subject to the risks faced by those industries. Such risks may materially and adversely affect our financial results. We derive a significant portion of our revenues from pharmaceutical and biotechnology companies and CROs serving these companies.
Added
We expect that pharmaceutical and biotechnology companies and CROs will continue to be a significant source of our revenues for the foreseeable future, including in our CMT and Preclinical product families.
Added
As a result, we are subject to risks and uncertainties that affect the pharmaceutical and biotechnology industries, such as government regulation, ongoing consolidation, changing economic policies such as tariffs, the impact of technological change, and reductions and delays in research and development expenditures by companies in these industries.
Added
In particular, the biotechnology industry is largely dependent on raising capital to fund its operations. If biotechnology companies that are our customers are unable to obtain the financing necessary to purchase our products, our business and results of operations could be materially and adversely affected.
Added
In addition, we are dependent, both directly and indirectly, upon general health care spending patterns, particularly in the research and development budgets of the pharmaceutical and biotechnology industries, as well as upon the financial condition and purchasing patterns of various governments and government agencies.
Added
As it relates to both the biotechnology and pharmaceutical industries, many companies have significant patents that have expired or are about to expire, which could result in reduced revenues for those companies.
Added
If pharmaceutical or biotechnology companies that are our customers suffer reduced revenues as a result of these patent expirations, they may be unable to purchase our products and our business and results of operations could be materially and adversely affected. Changes in government regulations may reduce demand for our products, adversely impact our revenues, or increase our expenses.
Added
We operate in many markets in which we and our customers must comply with federal, state, local and international regulations. We develop, configure and market our products to meet customer needs created by, and in compliance with, those regulations. These requirements include, among other things, regulations regarding manufacturing practices, product labeling, and advertising and post marketing reporting.
Added
We must incur expense and spend time and effort to ensure compliance with these complex regulations. Possible regulatory actions for non-compliance could include warning letters, fines, damages, injunctions, civil penalties, recalls, seizures of our products, and criminal prosecution.
Added
These actions could result in, among other things, substantial modifications to our business practices and operations; refunds, recalls, or seizures of our products; a total or partial shutdown of production in one or more of our facilities while we or our suppliers remedy the alleged violation; and withdrawals or suspensions of current products from the market.
Added
Any of these events could disrupt our business and have a material adverse effect on our revenues, profitability and financial condition. Risks Related to Our Business Reductions in customers ’ research budgets due to fluctuations in government funding or delays in government funding may adversely affect our business.
Added
Many of our customers are universities, government research laboratories, private foundations and other institutions whose funding is dependent on both the level and timing of funding from government agencies such as the NIH and similar domestic and foreign agencies. These customers represent a significant portion of our revenue.
Added
The level of funding and reimbursement rates under government programs relied on by these customers is subject to the political process and is often unpredictable. For example, the NIH announced on February 7, 2025, a policy significantly reducing research grants by limiting payments for indirect overhead.
Added
Further, government proposals to reduce or eliminate budget deficits have sometimes included reduced allocations to the NIH and other government agencies that fund our customers’ activities.
Added
Our revenue may be adversely affected if our customers forgo or delay purchases of our products and services as a result of uncertainties resulting from the NIH announcement or other government budget proposals, including reduced allocations to government agencies that fund our customers’ activities.
Added
NIH funding may not be directed towards projects and studies that require the use of our products and services.
Added
These factors could adversely affect our business and financial results. 7 Table of Contents We have recently announced a strategic consolidation of manufacturing operations, known as Project Viking, in connection with which we have incurred and will continue to incur restructuring costs; we may not realize the expected benefits of Project Viking or any future initiatives to reduce operating expenses.
Added
We may not realize the expected benefits from Project Viking, or from similar consolidation or restructuring initiatives that we may undertake in the future. In addition, we may incur additional restructuring costs in implementing such consolidation and restructuring plans or similar future plans, and such costs may exceed our expectations.
Added
The implementation of our restructuring efforts may not improve our operational and cost structure or result in greater efficiency for our organization and our efforts could result in harm to our business; and we may not be able to support sustainable revenue growth and profitability following such consolidations and we could potentially lose revenue as a result of our efforts.
Added
Our business is subject to economic, political and other risks associated with international sales and operations. We manufacture and sell our products internationally and, as a result, our business is subject to risks associated with doing business internationally.
Added
A substantial amount of our revenues is derived from international operations, and we anticipate that a significant portion of our sales will continue to come from outside the United States in the future. We anticipate that revenues from international operations will likely continue to increase as a result of our efforts to expand our business in markets abroad.
Added
In addition, a number of our manufacturing facilities and suppliers are located outside the United States.
Added
Our foreign operations subject us to certain risks, including: effects of fluctuations in foreign currency exchange rates; the impact of local economic conditions; fluctuations or reductions in economic growth in overseas markets including Asia and Europe; product preferences and seasonality and product requirements in foreign markets; difficulties in effectively establishing and expanding our business and operations in international markets; disruptions in foreign capital markets and trading markets; restrictions and potentially negative tax implications of transfers of capital across borders; differing labor regulations; the imposition of tariffs or import or export restrictions by the United States or foreign governments; other factors beyond our control, including potential political instability, terrorism, acts of war, natural disasters and diseases, pandemics; unexpected changes and increased enforcement of regulatory requirements and various state, federal and international, intellectual property, environmental, antitrust, anti-corruption, fraud and abuse (including anti-kickback and false claims laws) and employment laws; interruption to transportation flows for delivery of parts to us and finished goods to our customers; and laws and regulations on foreign investment in the United States under the jurisdiction of the Committee on Foreign Investment in the United States, or CFIUS, and other agencies, including the Foreign Investment Risk Review Modernization Act, or FIRRMA.
Added
A small percentage of our products are subject to export control regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”) and by the Export Administration Regulations administered by the U.S. Department of Commerce’s Bureau of Industry and Security (“BIS”).
Added
Based on the nature of the product, its ultimate end use and country of destination, we are sometimes subject to foreign assets control and economic sanctions regulations administered by OFAC, which restrict or prohibit our ability to transact with certain foreign countries, certain individuals and entities identified on the Treasury Department’s “Denied Parties List.” Under the OFAC regulations, the sale or transfer of certain equipment to a location outside the United States may require prior approval in the form of an export license issued by the BIS or the U.S.
Added
Department of State’s Directorate of Defense Trade Controls. Some potential international transactions may also be restricted or prohibited based on the location, nationality or identity of the potential end user, customer or other parties to the transaction or may require prior authorization in the form of an OFAC license.
Added
These risks may be exacerbated by geopolitical tensions in various regions of the world such as China, the Asia-Pacific region and the Middle East. Any delay in obtaining required governmental approvals could affect our ability to conclude a sale or timely commence a project, and the failure to comply with all such controls could result in criminal and/or civil penalties.
Added
Our overall success as a global business depends, in part, upon our ability to succeed in differing economic, social and political conditions. In order to continue to succeed in our international sales strategy, we must continue developing and implementing policies and strategies that are effective in each location where we do business, which could negatively affect our profitability.
Added
Levels of inflation and interest rates could negatively impact our revenues, profitability and borrowing costs. In addition, if our costs increase and we are not able to correspondingly adjust our commercial relationships to account for this increase, our net income would be adversely affected, and the adverse impact may be material.
Added
Sustained or increased inflation may result in decreased demand for our products, increased operating costs (including our labor costs), reduced liquidity, and limitations on our ability to access credit or otherwise raise debt and equity capital. In addition, the United States Federal Reserve has raised interest rates in response to concerns about inflation.
Added
Increases in interest rates have had, and could continue to have, a material impact on our borrowing costs.
Added
In an inflationary environment, we may be unable to raise the sales prices of our products at or above the rate at which our costs increase, which could reduce our profit margins and have a material adverse effect on our financial results and net income.
Added
We also may experience lower than expected sales if there is a decrease in spending on products in our industry in general or a negative reaction to our pricing. A reduction in our revenue would be detrimental to our profitability and financial condition and could also have an adverse impact on our future growth.
Added
We have substantial debt and other financial obligations, and we may incur additional debt in the future. Any failure to meet the requirements of our debt agreements and other financial obligations or maintain compliance with related covenants could harm our business, financial condition and results of operations.
Added
Further, compliance with these covenants may affect our ability to respond to changes in our business or to take certain actions. Our current credit agreement provides for term loans totaling $40.0 million (collectively, the “Credit Agreement”).
Added
As of December 31, 2025, we had outstanding borrowings of $40 million under the Credit Agreement. 8 Table of Contents Pursuant to the terms of the Credit Agreement, we are subject to various covenants, including negative covenants that restrict our ability to engage in certain transactions, which may limit our ability to respond to changing business and economic conditions.
Added
Such negative covenants include, among other things, limitations on our ability and the ability of our subsidiaries to incur debt or liens, make investments (including acquisitions), sell assets, and pay dividends on our capital stock.
Added
In addition, the Credit Agreement contains certain financial covenants, including a minimum liquidity level and adjusted EBITDA levels, each of which will be tested at the end of each fiscal quarter of the Company.
Added
If we are not able to maintain compliance with the covenants under the Credit Agreement, or are unsuccessful in obtaining waivers or amendments for any covenant defaults in the future, in addition to other actions our lenders may require, the amounts outstanding under the Credit Agreement may become immediately due and payable.
Added
Any such requirement for an immediate payment would negatively impact our financial condition. In addition, any failure to make scheduled payments of interest and principal on our outstanding indebtedness would likely harm our ability to incur additional indebtedness on acceptable terms.
Added
Our cash flow and capital resources may be insufficient to pay interest and principal on our debt in the future. If that should occur, our capital raising or debt restructuring measures may be unsuccessful or inadequate to meet our scheduled debt service obligations, which could cause us to default on our obligations and further impair our liquidity.
Added
Further, based upon our actual performance levels, our covenant relating to minimum liquidity level could limit our ability to incur additional debt, which could hinder our ability to execute our current business strategy. Our ability to make scheduled payments on our debt and other financial obligations and comply with financial covenants depends on our financial and operating performance.
Added
Our financial and operating performance will continue to be subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond our control. Failure within any applicable grace or cure periods to make such payments, comply with the financial covenants, or any other non-financial or restrictive covenant, would create a default under our Credit Agreement.
Added
Our management identified material weaknesses in our internal controls over financial reporting as of December 31, 2024.
Added
Although these material weaknesses have been remediated, failure to establish and maintain effective internal controls over financial reporting in the future could have a material adverse effect on our ability to report our financial condition, results of operations, or cash flows accurately and on a timely basis.
Added
As a publicly traded company, we are subject to the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley Act”). The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting.
Added
As part of its annual review of the effectiveness of our internal controls over financial reporting as of December 31, 2024, our management identified material weaknesses in our internal control over financial reporting.
Added
A material weakness is a deficiency or a combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
Added
The identified material weaknesses related to the design and operating effectiveness of our internal controls over (i) our order to cash cycle and (ii) our physical count of inventories. As a result of these material weaknesses, our management also concluded that our disclosure controls and procedures were not effective as of December 31, 2024.
Added
With respect to the material weaknesses described above, we have designed and implemented specific remediation initiatives, and as a result do not have any material weaknesses as of December 31, 2025.
Added
However, in the future, we may fail to identify other material weaknesses or significant deficiencies that could impair our ability to report our financial condition and results of operations accurately or on a timely basis.
Added
Continued or future failure to maintain effective internal control over financial reporting could result in financial statements that do not accurately reflect our financial condition or results of operations, may result in material misstatements in our financial statements and may also restrict our future access to the capital markets.
Added
Further, because of the inherent limitations in any system of controls, even effective internal control over financial reporting could fail to prevent or detect inaccuracies or misstatements. For a discussion of our internal control over financial reporting, see “Part II, Item 9A. Controls and Procedures” of this Annual Report on Form 10-K.
Added
Foreign currency exchange rate fluctuations may have a negative impact on our reported earnings. We are subject to the risks of fluctuating foreign currency exchange rates, which could have an adverse effect on the sales price of our products in foreign markets, as well as the costs and expenses of our foreign subsidiaries.
Added
A substantial amount of our revenues is derived from international operations, and we anticipate that a significant portion of revenues will continue to come from outside the United States in the future.
Added
As a result, currency fluctuations among the United States dollar, British pound, euro and the other currencies in which we do business have caused and will continue to cause foreign currency translation and transaction gains and losses. We have not used forward exchange contracts to hedge our foreign currency exposures.
Added
We attempt to manage foreign currency risk through the matching of assets and liabilities. In the future, we may undertake to manage foreign currency risk through hedging methods, including foreign currency contracts. We recognize foreign currency gains or losses arising from our operations in the period incurred.
Added
We cannot guarantee that we will be successful in managing foreign currency risk or in predicting the effects of exchange rate fluctuations upon our future operating results because of the number of currencies involved, the variability of currency exposure and the potential volatility of currency exchange rates.
Added
We cannot predict with certainty any changes in foreign currency exchange rates or the degree to which we can address these risks. 9 Table of Contents Issues in the development, deployment, and use of artificial intelligence technologies in our business operations, services and products may result in reputational harm, regulatory action, or legal liability, and any failure to adapt to such technological developments or industry trends could adversely affect the competitiveness of our business.
Added
Use of artificial intelligence (“AI”) to improve our internal business operations, or in the development or provision of products or services, poses risks and challenges. The use of AI, particularly generative AI, presents opportunities as well as risks that could negatively impact our business.
Added
The development, deployment, and use of AI, including within the life sciences industry, is still in its early stages, where the use of insufficiently developed AI technologies and premature deployment practices could result in unintended outcomes that harm the business.
Added
AI technologies may be developed using inaccurate, incomplete, flawed or biased algorithms, training methodologies or data, which could result in competitive harm, regulatory penalties, legal liability, or brand or reputational harm.
Added
Further, a failure to timely and effectively use or deploy AI and integrate it into new product offerings and services could negatively impact our competitiveness, particularly ahead of evolving industry trends and evolving consumer demands. We may be unable to devote adequate financial resources to develop or acquire new AI technologies and systems in the future.
