The company faces competition from larger equipment and service providers with greater financial resources and market recognition[38](index=38&type=chunk) - Competition is based on price, customer service, flexibility, and the quality/reliability of compressors and services[38](index=38&type=chunk) - Increased size and geographic breadth offer significant advantages in the compressor industry, as sales, support, and maintenance personnel requirements do not increase proportionately with fleet size[39](index=39&type=chunk) [Sales Backlog](index=12&type=section&id=Backlog) - The 2018 sales backlog is scheduled to be fulfilled primarily by the end of the third quarter of 2019[40](index=40&type=chunk) Sales Backlog (as of December 31) | Year | Backlog Amount (Millions) | | :--- | :------------------------ | | 2018 | $14.8 | | 2017 | $7.8 | [Workforce Information](index=12&type=section&id=Employees) -

Adverse macroeconomic conditions and low oil/natural gas prices can negatively impact revenue and profitability by reducing customer capital expenditures and affecting the collectability of receivables[70](index=70&type=chunk)[71](index=71&type=chunk) - The industry is highly competitive, with larger players having greater financial resources, potentially leading to reduced profitability and loss of market share[73](index=73&type=chunk)[74](index=74&type=chunk) - A reduction in demand or prices for natural gas, particularly from unconventional sources, could adversely affect the business, as evidenced by a **32% revenue decline** and a drop in compressor utilization from **76.0% in 2014 to 52.9% in 2018**[75](index=75&type=chunk)[78](index=78&type=chunk) - The industry's cyclical nature leads to volatile results, with periods of low demand intensifying competition and resulting in lower rental rates[79](index=79&type=chunk) - Increased regulation or a ban on hydraulic fracturing techniques, as well as investigations into produced water disposal, could reduce demand for compressors and introduce operational uncertainty[80](index=80&type=chunk)[81](index=81&type=chunk)[82](index=82&type=chunk) - The company is subject to extensive environmental laws, with potential liabilities for cleanup costs, damages, and penalties for non-compliance, which could harm its financial condition[83](index=83&type=chunk)[84](index=84&type=chunk)[85](index=85&type=chunk) [Company-Specific Risks](index=20&type=section&id=Risks%20Associated%20With%20Our%20Company) - A majority of compressor rentals are short-term (six months or less), and non-renewal or inability to re-rent at comparable rates could materially impact revenue and cost recovery[86](index=86&type=chunk) - The company is exposed to substantial liability claims from product accidents or failures, which may exceed insurance coverage or lead to increased premiums[87](index=87&type=chunk)[90](index=90&type=chunk) - Reliance on a few major customers (one customer accounted for **28% of 2018 revenue** and **26% of accounts receivable**) means the loss of such customers could adversely affect operations and cash flow[88](index=88&type=chunk) - The loss of key executive management members, particularly CEO Stephen C Taylor, could materially affect business operations due to reliance on their leadership and expertise[89](index=89&type=chunk) - Erosion of customer financial condition, driven by weak oil/gas markets, could lead to reduced spending on products and services, impacting the company's growth[92](index=92&type=chunk) - Inability to employ and retain qualified technical personnel, due to high demand and limited supply, could hamper operations or increase costs[93](index=93&type=chunk) - Expansion of the compressor rental fleet and business growth require substantial capital, which may not always be available on acceptable terms, potentially impacting financial condition[94](index=94&type=chunk)[95](index=95&type=chunk) - The company's debt levels, though currently low (**$417,000 outstanding** on a **$30 million line of credit** as of December 31, 2018), could limit future financing and make the company vulnerable to economic downturns if fully utilized[96](index=96&type=chunk)[99](index=99&type=chunk) - The credit agreement contains covenants (e.g, minimum leverage ratio, commitment coverage ratio) that limit operating and financial flexibility; a breach could accelerate debt and allow the bank to foreclose on assets[101](index=101&type=chunk)[102](index=102&type=chunk) - Failure to successfully acquire or integrate additional businesses could limit growth and negatively impact results, due to complexities, costs, and potential loss of key employees/customers[103](index=103&type=chunk) - Failure to effectively manage growth and expansion could strain management and resources, impairing the ability to hire, train, and upgrade infrastructure[104](index=104&type=chunk) - Liabilities under warranties and indemnification provisions, especially for complex equipment in harsh environments, could materially affect earnings and reputation[105](index=105&type=chunk)[106](index=106&type=chunk) - Changes in income tax laws, regulations, or audit assessments could result in increased tax provisions and affect operating results[107](index=107&type=chunk)[108](index=108&type=chunk) - Failure to maintain effective internal controls over financial reporting could lead to unreliable financial reports, fraud, and a decrease in stock price[109](index=109&type=chunk) - The company is exposed to risks from computer system failures or cyber security threats, which could disrupt operations or lead to data loss, although measures are in place to minimize these risks[110](index=110&type=chunk)[111](index=111&type=chunk) [Common Stock Risks](index=26&type=section&id=Risks%20Associated%20With%20Our%20Common%20Stock) - The trading price of common stock is subject to substantial fluctuations due to various factors, including business strategy, financial results, market conditions, and oil/natural gas prices[112](index=112&type=chunk) - Substantial future sales of common stock by institutional investors (**22.7% ownership**) or directors/officers (**6.2% ownership**) could negatively impact the stock price[113](index=113&type=chunk) - A relatively low number of outstanding shares contributes to limited liquidity and potential price volatility[114](index=114&type=chunk) - Future issuance of debt or equity securities could dilute existing ownership and impose restrictions on operations[115](index=115&type=chunk) - If securities analysts downgrade the stock or cease coverage, the stock price could decline due to reduced market visibility[116](index=116&type=chunk) - Provisions in governing documents, such as staggered board terms, lack of cumulative voting, and high vote requirements for board changes, could hinder a change in control[117](index=117&type=chunk) [Unresolved Staff Comments](index=28&type=section&id=Item%201B.%20Unresolved%20Staff%20Comments) There are no unresolved staff comments -
