Previous wording

Our cash flows may be insufficient to provide adequate working capital in the future and we may require additional financing to fund existing operations as well as our growth plan. We paid off and terminated our existing credit facility with UMB Bank in September 2024. There is no assurance that we will be able to replace such facility or that any additional financing will be available if required, or, even if available, that it would not materially dilute the ownership percentage of our then existing shareholders, result in increased expenses or result in covenants or special rights that would restrict our operations.

Previous wording

Our success depends upon the continued contributions of our executive officers and certain other employees, many of whom have many years of experience with us and would be extremely difficult to replace. We must also attract and retain experienced and highly skilled engineering, sales and marketing and managerial personnel. Competition for qualified personnel is intense in our industry, and we may not be successful in hiring and retaining these people. If we lost the services of our executive officers or our other highly qualified and experienced employees or cannot attract and retain other qualified personnel, our business could suffer as a result of less effective management due to loss of accumulated knowledge of our business or through less successful products due to a reduced ability to design, manufacture and market our products.

In addition, implementation of a business strategy may lead to the disruption of our existing business operations. For example, the contingent risks associated with outsourcing certain of our existing manufacturing operations to third parties, as is the case with our use of third party manufacturers, primarily in Canada and Mexico, could materially impact our financial condition or results of operations and/or could disrupt our existing operations, especially if a contract manufacturer is unable to meet its commitments under any agreements or encounters financial difficulty. Furthermore, our efforts to outsource certain of our manufacturing operations may require additional management time and effort to implement successfully, and lead to higher than anticipated capital expenditures.

We continually evaluate potential acquisitions and consider acquisitions an important part of our future growth strategy. In the past, we have made acquisitions of, or significant investments in, other businesses with synergistic products, services and technologies and plan to continue to do so in the future. There can be no assurance that we will be able to identify suitable acquisition opportunities in the future or that we will be able to consummate any such transactions on terms and conditions acceptable to us.

Previous wording

Additionally, we cannot predict if or when acquisitions will be completed, and we may face significant competition for acquisition targets. Acquisitions involve numerous risks, including: (a) difficulties in integrating the operations, technologies, management information systems, products and personnel of the acquired companies; (b) diversion of management’s attention from normal daily operations of the business; (c) loss of key employees; (d) difficulties in entering markets in which we have no or limited prior experience and where our competitors in such markets have stronger market positions; (e) difficulties in complying with regulations, such as antitrust and environmental regulations, and managing risks related to an acquired business; (f) an inability to timely obtain financing, including any amendments required to our existing financing agreement; (g) an inability to implement uniform standards, controls, procedures and policies; (h) undiscovered and unknown problems, defects, liabilities or other issues related to any acquisition that become known to us only after the acquisition; and (i) loss of key customers or suppliers. Any of these risks could have a material adverse effect on our business, results of operations, financial condition, or cash flows, particularly in the case of a large acquisition.

Previous wording

As of September 30, 2024, one Thermal Processing Solutions customer represented 12% of our accounts receivable. A concentration of our receivables from one or a small number of customers places us at risk. A significant change in the liquidity or financial position of any of our customers that purchase large systems could have a material impact on the collectability of our accounts receivable and our future operating results. We attempt to manage this credit risk by requiring significant partial payments prior to shipment, where appropriate, and by actively monitoring collections. We also require letters of credit from certain customers depending on the size of the order, type of customer or its creditworthiness and its country of domicile. Our major customers may seek and, on occasion, may receive pricing, payment or other commercial terms that are less favorable to us than the current terms we customarily obtain. If any one or more of our major customers were to seek to re-negotiate their agreements on more favorable terms, or not pay us or continue business with us, it could adversely affect our business, financial position and results of operations.

Previous wording

There are also inherent execution risks in starting up a new factory or expanding production capacity, whether one of our own factories or that of our contract manufacturers, as well as risks to moving production to different contract manufacturers, which could increase costs and reduce our operating results. In the fourth quarter of fiscal 2023, we opened a new SiC consumables facility in Spartanburg, South Carolina to complement our manufacturing facility in Carlisle, Pennsylvania. We are also working with contract manufacturing facilities in Canada and Mexico. The establishment and operation of new manufacturing facilities or contract manufacturing involves significant risks and challenges, some of which we have experienced and may experience in the future, including, but not limited to, the following: (a) design and construction delays and cost overruns; (b) issues in installing and qualifying new equipment and ramping production; (c) poor production process yields and reduced quality control; and (d) insufficient personnel with requisite expertise and experience to operate a manufacturing facility for the products we manufacture.

We have identified material weaknesses in our internal control over financial reporting which, if not remediated, could result in material misstatements in our financial statements.

Current wording

In the past we have identified material weaknesses in our internal control over financial reporting which, if not remediated, could result in material misstatements in our financial statements.

Previous wording

During the fourth quarter ended September 30, 2023, we identified a material weakness in internal control related to ineffective information technology general controls in the areas of user access, segregation of duties, and program change-management over information technology systems that support substantially all of the Company’s financial reporting processes. This resulted in our inability to segregate user duties within the Company’s business processes. A substantial portion of the Company's controls are dependent upon the information derived from the information technology systems and therefore the dependent controls were concluded to be ineffective. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual consolidated financial statements will not be prevented or detected on a timely basis.

Amtech and our subsidiaries are defendants from time to time in actions for matters arising out of our business operations. The manufacture and sale of our products, which, in our customers’ operations, involve toxic materials and robotic machinery, involve the risk of product liability claims. In addition, a failure of one of our products at a customer site could interrupt the business operations of our customer. Our existing insurance coverage limits may not be adequate to protect us from all liabilities that we might incur in connection with the manufacture and sale of our products if a successful product liability claim or series of product liability claims were brought against us. As of September 30, 2024 and 2023, our accrued warranty costs amounted to $0.6 million and $1.0 million, respectively. Our assumptions regarding the durability and reliability of our products may not be accurate, and because our products have relatively long warranty periods, we cannot assure you that the amount of accrued warranty by us for our products will be adequate considering the actual performance of our products or that we won't experience higher than expected warranty claims. If we experience a significant increase in warranty claims, we may incur significant repair and replacement costs associated with such claims. Furthermore, widespread product underperformances or failures will damage our reputation and customer relationships and may cause our sales to decline, which in turn could have a material adverse effect on our business, financial condition and results of operations.

Historically, our common stock has experienced substantial price volatility, particularly as a result of fluctuations in our revenue, earnings and margins over the past few years, and variations between our actual financial results and the published expectations of analysts. For example, during the two-year period ended September 30, 2024, the price of our common stock has ranged from $11.98 to $3.37. If our future operating results or margins are below the expectations of stock market analysts or our investors, our stock price will likely decline.
