However, not all forward-looking statements contain these identifying words. All forward-looking statements included herein are based on information available to us as of the date hereof and speak only as of such date. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements. The forward-looking statements contained in or incorporated by reference into this Annual Report on Form 10-K reflect our views as of the date of this Annual Report on Form 10-K about future events and are subject to risks, uncertainties, assumptions, and changes in circumstances that may cause our actual results, performance, or achievements to differ significantly from those expressed or implied in any forward-looking statement. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future events, results, performance, or achievements. A number of factors could cause actual results to differ materially from those indicated by the forward-looking statements and other risks detailed from time to time in our reports to the Securities and Exchange Commission (the “SEC”).

our belief that by developing and aggregating strategic solutions, we are unique in our ability to offer comprehensive national solutions in the highly fractionalized waste, disposal, and recycling service business; our plan to expand to serve growing industries that we do not currently service, but that generate waste streams and recyclables that can benefit from our ability to manage a large variety of waste streams and recyclables, respond quickly to service requests, and provide what we consider to be industry-leading collection, processing, and data reporting; our plan to expand the types of waste streams and recyclables covered by our services; our plan to capitalize on the significant market, technology, and process opportunities available in the environmental and recycling services industry;

our intention to emphasize the monetary advantages of recycling by demonstrating to businesses their ability to capture the commodity value of their waste streams and recyclables, reduce their disposal costs, enhance their management of environmental risks, enhance their legal and regulatory compliance, and achieve their sustainability goals; our intention to continue to expand the customer base for our services by focusing on the expertise we have gained and the value proposition that we offer to our business customers in terms of lower overall removal costs, recyclable commodity value, flexible programs, broad service offerings, and a national footprint that we believe provides us with competitive advantages in expanding our customer base; our intention to leverage the demands by governmental authorities and by the public to expand efforts to recycle materials because of concerns about sustainability, greenhouse gases, global warming, pollution, and other environmental concerns; our expectation that the recycling industry will continue to increase as landfill space decreases and businesses and consumers seek alternatives to delivering their recyclables and disposables to landfills; our expectation that the Environmental Protection Agency (“EPA”) and state and local governments will continue the present trend of restricting the amount of potentially recyclable material bound for landfills; our belief that governmental restrictions, along with the economic value of recyclables, may create additional opportunities as proper disposal of materials becomes more specialized; our goal to be a leading environmental services company; the key elements of our strategy to achieve our goals; our plans to continue to broaden the range of industries we serve and the nature and extent of the services we provide, which enables us to constantly target new customers and provide additional services to existing customers;

our strategic goal to continue to diversify our customer base; our intention to conduct our operations in compliance with applicable laws and regulations and to assist our customers in their compliance with applicable environmental laws and regulations; our plan to continue to pursue an “asset light” strategy that utilizes third-party vendors or subcontractors for the collection, sorting, and processing of recyclable and waste materials for businesses; our belief that this strategy results in a scalable business model; our expectations regarding capital expenditures; our plan to increase our recycling and waste services business; our expectations regarding our capital requirements and the uses of such capital; our belief that there is significant competition for qualified personnel with the skills and knowledge that we require; our expectation that we will enter into strategic alliances; our plan to review strategic opportunities to buy other businesses that would complement our current service offerings, expand the scope of our service offerings, expand the breadth of our markets and sales channels, enhance our technical capabilities, or otherwise offer growth opportunities; our acquisition strategy; our intent to further acquire other businesses; our belief that we are well positioned to identify and evaluate acquisition candidates and assess their growth prospects; our belief that we are regarded as an attractive acquirer; our intention to issue additional securities pursuant to our equity incentive plan and our employee stock purchase plan may issue equity or convertible securities in the future; our plan to retain any future earnings to finance our operations and growth plans; and our belief that our existing cash and cash equivalents, available borrowing under our credit facilities, placements of our securities, and cash expected to be generated from operations will be sufficient to fund our operations for the next 12 months.
