continuing research and development efforts to develop new products and further enhance our existing products. Further, we expect to incur additional costs associated with operating as a public company. As a result, we may need additional funding for expenses related to our operating activities, including selling, general and administrative expenses and research and development expenses.
Because of the numerous risks and uncertainties associated with product development and commercialization, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability. Until such time, if ever, as we can generate substantial revenue sufficient to achieve profitability, we expect to finance our operations through a combination of equity offerings, debt financings and strategic alliances. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we are unable to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back or discontinue the further development and commercialization efforts of one or more of our products, or may be forced to reduce or terminate our operations.
We believe that our existing cash and cash equivalents and revenue from product and service will enable us to fund our operating expenses, capital expenditure requirements and debt service payments for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See “Liquidity and Capital Resources.”
Global Economic Conditions
We are continuing to closely monitor macroeconomic factors, including, but not limited to, continued inflationary and interest rate pressures, challenging capital market conditions and the limited availability of financing alternatives, which may have an impact on our business, results of operations and financial results.
We are closely monitoring continued economic uncertainty in the United States and abroad, including volatility in the global markets and the rise and fluctuations in inflation and interest rates. These developments and the potential worsening of other macro-economic conditions present risks for us, and our suppliers and customers. For example, general inflation in the United States, EMEA and other geographies has recently been at levels not experienced in recent decades, which has led to higher prices for our raw materials and other inputs, as well as higher salaries and travel expenses, which could continue to negatively impact our business by increasing our cost of sales and operating expenses. General inflation could also negatively impact our business if it leads to spending pressure and decreased available capital for our customers to deploy to purchase our products and services.
In addition, while the United States Federal Reserve has recently begun to lower interest rates, it has over the past couple of years raised, and may again raise, interest rates in response to concerns about inflation. Inflation, together with increased interest rates, may cause our customers to reduce or delay orders for our goods and services thereby causing a decrease in or change in timing of sales of our products and services. The impact of future inflation and interest rate fluctuations on the results of our operations cannot be accurately predicted.
Challenging capital market conditions and the limited availability of financing alternatives, together with inflationary and interest rates pressures, may contribute to more cautious spending by our customers. Certain of our pharmaceutical and biotechnology customers, including bioprocessing customers, may evaluate their inventory levels, cash on hand and path to profitability, and institute cost controls and take other actions to reduce or delay purchases of our products and services. We cannot accurately predict the full impact of current macroeconomic factors on the budgets and capital expenditures of our customers, or the timing of the normalization of customer purchasing patterns.
We are closely monitoring the ongoing military conflict between Russia and Ukraine, and the ongoing hostilities in Israel, Lebanon, and the Gaza Strip and other locations in the Middle East. Although we do not directly source any material products or supplies from Russia, Ukraine, Israel, Lebanon or the Gaza Strip, our customers in Europe and the Middle East could be impacted by extended conflicts or an escalation of these conflicts into neighboring countries.
While it is difficult to predict all of the impacts these global economic events and continued inflationary and interest rate pressures will have on our business and to predict the effects of these factors on our customers’ spending in the near term, we believe the long-term opportunity that we see for our products and services remain unchanged.
