PART I

ITEM 1. BUSINESS

Overview

Overview

Surnadevelops, designs, and distributes cultivation technologies for controlled environment agriculture (“CEA”). The Company’s customers include state-regulated cannabis cultivation facilities as well as traditional indoor agricultural facilities, including organic herb and vegetable producers.

Surna’s technologies include a comprehensive line of optimized lighting, environmental control, air sanitation and cultivation facilities. These technologies are designed to meet the specific environmental conditions required for indoor cultivation and to dramatically reduce energy and water consumption.

In addition, Surna offers mechanical design services specific to hydronic cooling including mechanical equipment and piping design.

Products and Services

Surna Chillers

Surna’s liquid-based process cooling system provides a more reliable and efficient thermal cooling solution compared to typical air conditioning products:

Surna Reflectors

Surna’s reflector optimizes light delivery to the plant canopy. Thanks to the reflector’s internal technology, the bulb is able to produce up to 9.1% more usable light without any increase in energy consumption. Light-on-target reflectivity is also increased due to the unique design and shape of the reflector, eliminating light wasted illuminating walls and aisles. The water-cooled version uses a unique automation protocol to employ “point-source” heat removal drastically reducing the energy required to capture and remove the heat generated by the bulb.

Bio-Security

Surna offers a full-service air sanitation technology program for mold and mildew risk mitigation to cultivators. This program uses a combination of site monitoring and photocatalytic oxidation equipment to maintain facility standards while destroying harmful airborne microbes without the production of byproducts.

Services

Surna provides a full-service engineering package for designing and engineering commercial scale thermodynamic systems specific to indoor grow facility conditions. Once the design is complete, Surna’s project management team oversees its customers’ installation through system commissioning. Surna’s on-site commissioning program is designed to ensure that the target environment is achieved. Surna then offers an ongoing maintenance plan to maintain the integrity of the system through regularly scheduled visits with a goal of keeping its customers’ system operating at peak performance.

Automation

Surna understands the importance of maintaining a consistent grow environment and as such seeks to provide “smart” equipment with onboard intelligence allowing the cultivator the ability to automate its system. Employing a number of technologies, Surna’s building automation controls can be scaled to address a variety of customer needs and expectations. From simple environment measuring devices to full scale system automation, Surna believes it understands the needs of the cultivator.

Hybrid Building

Surna’s comprehensive cultivation facility (“Hybrid Building”) combines the advantages of a greenhouse with those of an indoor grow operation for indoor cultivators seeking efficiency and accelerated time to market. The Hybrid Building uses the sun as its primary light source and high power LED lights for supplemental lighting while maintaining the environmental and security controls of an indoor facility. Surna’s technology is employed into this one fully operational building seeking to give the grower the best technology available on the market today.

Air SanitationProduct Development

Surna offers air sanitation technology for mold and mildew risk mitigation to cultivators. This technology usesplaces a process of photocatalytic oxidation to destroy harmful airborne microbes without the production of byproducts.

Services

Surna offers full mechanical, electrical, and plumbing (“MEP”) services including designing and engineering commercial scale thermodynamic systems specific to indoor grow facility conditions. Surna also offers workflow design to decrease the risk of facility and crop contamination.

Product Development

Surna engages inpriority on new product development and improvement both through its internal product development staff and in partnershippartnerships with other commercial entities. In the fiscal year ended December 31, 2015,2016, the Company spent $707,517$349,000 towards the development of new products such asin the areas of lighting, reflector,climate control, bio-security, water purification, system automation and the hybrid building, and integrated software systems, and, in 2014, the Company spent $319,430 on product development.building.

Intellectual Property

Surna relies on a combination of patent and trademark rights, trade secrets, laws that protect intellectual property, confidentiality procedures, and contractual restrictions with its employees and others to establish and protect its intellectual property rights. As of March 31, 2016,2017, the Company has eight pending patent applications and four issued patents. The pending patent applications are a combination of PCT, provisional, utility and design patent applications that are directed to certain core Company technology. The Company’s four issued patents are U.S. design patents related to the Company’s Reflector.reflector. The U.S. design patents provide protection for 14 years from the date of issue. Utility patents provide protection for 20 years from the earliest non-provisional application filing date. The Company also is actively pursuinghas registered trademark registrationregistrations around its core brand (“Surna”) in the United States and select foreign jurisdictions, as well as the Surna logo and the combined Surna logo and name in the United States. Our wordmark is also registered in the European Union and is pending registration in Canada. These are contained in three applicationstrademarks with the United States Patent and Trademark Office (“USPTO”). Subject to ongoing use and renewal, trademark protection is potentially perpetual.

Operating segments

Surna currently operates in one primary business segment, which encompasses designing, manufacturing, and distributing indoor climate control systems, including but not limited to chillers, lights, reflectors, and irrigation systems, for use in conjunction with the state-regulated cannabis and CEA industry.

Competition

Surna’s chilled water system products and services compete with various national and local HVAC (heating, ventilation, and air conditioning) providers who traditionally resell, design, and implement climate control systems for comfort cooling of schools, offices, or other large buildings. Surna differs from these competitors by providing hydronic cooling systems tailored specifically for managing the distinct challenges of managingin connection with the significant heat and humidity loads associated with cultivation of indoor crops.

Surna’s dehumidification products face competition from other dehumidification manufacturers. Surna provides its customers and clients with dehumidification options that it believes are more cost effective and more efficient at removing humidity than its competitors in the indoor cultivation space.

Few

Surna believes that few manufacturers of these products have expertise in the cannabis market and understand the needs of growers. Surna, however, is equipped to customize products for the cannabis market and advise growers on appropriate products to maximize crop yield. The Company expects increased competition in both the climate control and services divisions in the cannabis sector as an increasing number of states legalize the cultivation, distribution, and consumption of the crop.

Employees

As of March 31, 2016,2017, Surna has 3228 full-time employees and one part-time employee.employees. The Company may, however, utilize and has in the past utilized the services of a number of consultants, independent contractors, and professionals. Proceeding in this manner allows the Company to operate efficiently and pragmatically. Additional employees will be hired in the future depending on need and the Company’s expansion.

Government Regulation

Surna’s chillers are subject to state and municipal regulations regarding energy-efficiency standards often incorporated into building codes. Many states and municipalities have adopted some version of Standard 90.1 as published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (“ASHRAE”); however, some states and municipalities have or may in the future adopt alternative standards that may be more or less restrictive than Standard 90.1. Similarly, Standard 90.1 is itself regularly updated—most recently in 2013. Each update of the standard generally reflects the availability of increasingly efficient technologies, resulting in stricter energy-efficiency requirements. The Company anticipates that its products will comply with these standards. With every product line, Surna offers a product that meets or exceeds the Standard 90.1.

Otherwise, the Company is subject substantially to the same government regulations that affect businesses generally. See, however, Item 1A - Risk Factors – “Federal“U.S. Federal and foreign regulation and enforcement may adversely affect the implementation of marijuana laws and regulations may negatively impact our revenue and profit” “We or we could be found to be violating the Controlled Substances Act or other U.S. federal, state or foreign laws, related to marijuana,” and“Litigation by states affected by marijuana legalization,” “Variations in state and local regulation and enforcement in states that have legalized cannabis that may restrict marijuana-related activities, including activities related to cannabis, may negatively impact our revenue and profit.profit,” and “We and our customers may have difficulty accessing the services of banks, which may make it difficult to sell our products and services.”

Corporate History

Surna incorporated in the State of Nevada on October 15, 2009.

Spin-off of Trebor Resource Management Group, Inc. Effective March 25, 2014, Surna completed the issuance of a dividend of all of the Company’s ownership in Trebor Resource Management Group, Inc. (“Trebor”), a wholly-owned subsidiary, to its shareholders, resulting in Trebor becoming a separate entity. Trebor was seeking to identify and develop joint opportunities with third parties in the mining business in the Philippines. See Item 1A - Risk Factors – “If it were determined that our spin-off of Trebor Resource Management Group, Inc. in March 2014 violated federal or state securities laws, we could incur monetary damages, fines or other damages that could have a material adverse effect on our financial condition and prospects.”

Acquisition of Safari Resource Group, Inc. On March 26, 2014, Surna exchanged 80,201,250 shares of the Company’s unregistered shares of common stock and 77,220,000 shares of the Company’s unregistered shares of preferred stock for 100% of the outstanding common stock of Safari Resource Group, Inc. (“Safari”), a Nevada corporation. Safari possessed intellectual property and strategic relationships that were integral to Surna’s entrance into the CEA and state-regulated cannabis markets.

Spin-off of Surna Media, Inc. On June 30, 2014, Surna entered into a separation agreement with Lead Focus Limited, a British Virgin Islands company, which is owned by a combination of prior officers, directors, and others, in which Surna sold its subsidiary, Surna Media, Inc. (“Surna Media”), including Surna Media’s subsidiaries, Surna HK and Flying Cloud, in exchange for a payment of $1 in cash and the buyer’s assumption of all of the liabilities of Surna Media and its subsidiaries. As a result of this sale, Surna eliminated from its balance sheet all assets and liabilities associated with Surna Media and recorded a credit of $2,643,881 to its additional paid in capital. As a result of this sale, Surna ceased its operations relating to the development of web and mobile games, social networks, telecommunication services, IT support services, and open-source software.

Acquisition of Hydro Innovations, LLC. On July 25, 2014, Surna acquired 100% of the membership interests of Hydro Innovations, LLC, a Colorado limited liability company (“Hydro”) from its owners, Stephen Keen and Brandy Keen (the “Keens”), for a price of $500,000 payable by assumption of a $250,000 promissory note on the books and records of Hydro as well as issuance of a $250,000 promissory note to the Keens. The Keens’ promissory note bears interest at the rate of 6% per annum and is payable in monthly installments of $5,000 with a balloon payment for the balance of accrued interest and principal due on July 18, 2016, though it may be prepaid in whole or in part at any time. In addition, Surna entered into employment agreements with the Keens. Pursuant to the terms of the employment agreements, the Company agreed to employ Ms. Keen as Vice President of Sales and Mr. Keen as Vice President of Product Development, each for a period of three years beginning on July 25, 2014 and at an annual base salary of $96,000, as well as certain stock compensation, which is subject to review annually by the Board of Directors. Notwithstanding the 3-year term, both of the Keens employment agreements are at-will and may be terminated at any time, with or without cause. Mr. Keen’s position changed to President and Chief Executive Officer on August 28, 2015 and then to Director of Product Development on June 15, 2016. The terms of his employment agreement did not change with his changes in position.

ITEM 1A. RISK FACTORS

Certain factors may have a material adverse effect on our business, financial condition, and results of operations. You should consider carefully the risks and uncertainties described below, in addition to other information contained in this Annual Report on Form 10-K, including our consolidated financial statements and related notes. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any of the following risks actually occurs, our business, financial condition, results of operations, and future prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business

We are solely dependent upon the funds we have raised so far and the support of our majority shareholders, including Stephen and Brandy Keen, to continue our operations, which may be insufficient to achieve significant revenue, and we may need to obtain additional financing, which may not be available to us.

We may require additional cash resources to finance our continued growth or other future developments, including any investments or acquisitions we may decide to pursue. We may need additional funds to complete further development of our business plan to achieve a sustainable sales level where ongoing operations can be funded out of revenue. We extinguished $3,350,523 in convertible debt owed to investors (net of an additional $500,000 in short-term borrowing), strengthening our balance sheet. In addition, in March 2017 we raised $2,685,000 in a private placement offering of common stock and warrants to accredited investors. With the addition of these funds we believe we have sufficient cash on hand to continue our operations through the year ended December 31, 2017. Before that date we will need to raise additional funds or move to profitable operations, as to which there can be no assurance.

We may need additional capital in the future, which could dilute the ownership of current shareholders or we may be unable to secure additional funding in the future or to obtain such funding on favorable terms.

Historically, we have raised equity and debt capital to support our operations. To the extent that we raise additional equity capital, existing shareholders will experience a dilution in the voting power and ownership of their common stock, and earnings per share, if any, would be negatively impacted. Our inability to use our equity securities to finance our operations could materially limit our growth. Any borrowings made to finance operations could make us more vulnerable to a downturn in our operating results, a downturn in economic conditions, or increases in interest rates on borrowings that are subject to interest rate fluctuations. The amount and timing of such additional financing needs will vary principally depending on the timing of new product launches, investments and/or acquisitions, and the amount of cash flow from our operations. If our resources are insufficient to satisfy our cash requirements, we may seek to issue additional equity or debt securities or obtain a credit facility. If our cash flow from operations is insufficient to meet our debt service requirements, we could be required to sell additional equity securities, refinance our obligations, or dispose of assets in order to meet debt service requirements. There can be no assurance that any financing will be available to us when needed or will be available on terms acceptable to us. Our failure to obtain sufficient financing on favorable terms and conditions could have a material adverse effect on our growth prospects and our business, financial condition and results of operations.

Even if we obtain more customers, there is no assurance that we will make a profit.

Even if we obtain more customers, there is no guarantee that we will be able to generate a profit. Because we are a small company and do not have much capital, we must limit our products and services. Because we will be limiting our marketing activities, we may not be able to attract enough customers to buy our products to operate profitably. If we cannot operate profitably, we may have to suspend or cease operations.

If we fail to establish or maintain effective internal control over financial reporting, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of our common stock may, therefore, be adversely impacted.

Our reporting obligations as a public company will place a significant strain on our management, operational and financial resources, and systems for the foreseeable future. Annually, we are required to prepare a management report on our internal control over financial reporting containing our management’s assessment of the effectiveness of our internal control over financial reporting. Management has presently concluded that our internal control over financial reporting is not effective and shall report such in management’s report in this annual report on Form 10-K. In the event that the Company’s status with the U.S. Securities & Exchange CommissionSEC changes to that of an accelerated filer from a smaller reporting company, our independent registered public accounting firm will be required to attest to and report on our management’s assessment of the effectiveness of our internal control over financial reporting. Under such circumstances, even if our management concludes that our internal control over financial reporting are effective, our independent registered public accounting firm may still decline to attest to our management’s assessment or may issue a report that is qualified if it is not satisfied with our controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us.

Our principal shareholders have substantial influence over our Company and their interests may not be aligned with the interests of our other holders of our common stock.

This concentration of ownership amongst members of our Board of Directors, including Stephen and Brandy Keen, may discourage, delay, or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our shares. Alternatively, these principal shareholders may cause a merger, consolidation, or change of control transaction even if our other shareholders oppose it. As a result, no assurance can be made that the prices paid or to be paid by the Company for the assets acquired or to be acquired were fair to our Company or its shareholders.

Our Directors and Officers possess the majority of our voting power, and through this ownership, control our Company and our corporate actions.

The officer/director group has a controlling influence in determining the outcome of any corporate transaction or other matters submitted to our shareholders for approval, including mergers, consolidations, and the sale of all or substantially all of our assets, election of directors, and other significant corporate actions. Such officer and/or shareholderofficers and directors may also have the power to prevent or cause a change in control. In addition, without the consent of these shareholders, we could be prevented from entering into transactions that could be beneficial to us. The interests of these shareholders may give rise to a conflict of interest with the Company and our shareholders.

U.S. Federal and foreign regulation and enforcement may adversely affect the implementation of marijuana laws and regulations and may negatively impact our revenue and profit or we may be found to be violating the Controlled Substances Act or other U.S. federal, state, or stateforeign laws.

Currently, twenty-threetwenty-eight states and the District of Columbia permit some form of whole-plant cannabis use and cultivation. Thirty-sevencultivation either for medical or recreational use. Thirty-eight states have adoptedallow or are considering legislation to permitallow the possession and use of non-psychoactive cannabidiol (“CBD”) oil infor some situations.medical conditions only. There are efforts in many other states to begin permitting cannabis use and/or cultivation in various contexts.contexts, and it has been reported that eleven states are actively considering bills to permit recreational use or to decriminalize the use of marijuana. Nevertheless, the federal government continues to prohibit cannabis in all its forms as well as its derivatives. Under the federal Controlled Substances Act (the “CSA”), the policy and regulations of the federal government and its agencies is that cannabis has no medical benefit, and a range of activities including cultivation and use of cannabis is prohibited. Until Congress amends the CSA or the executive branch deschedules or reschedules cannabis under it, there is a risk that federal authorities may enforce current federal law. Enforcement of the CSA by federal authorities could impair the Company’s revenue and profit, and it could even force the Company to cease operating entirely.entirely in the cannabis industry. The risk of strict federal enforcement of the CSA in light of congressional activity, judicial holdings, and stated federal policy, including enforcement priorities, remains uncertain.

The Attorneys General

We have recently begun selling products and services to cannabis growers in Canada, where medical marijuana currently is legal across the country both federally and provincially. Canadian Prime Minister Trudeau also is expected to introduce legislation to legalize, but strictly control, recreational use of marijuana. We believe Canada, with its federally legal regime, represents a significant business opportunity for Oklahoma and Nebraska soughtus, but there can be no assurance that we will be able to file a lawsuit against Colorado for its cannabis regulatory regime directly with the U.S. Supreme Court under its principlesmake any additional sales of original jurisdiction, but the Court, on March 21, 2016, denied them permission to do so. However, nothing prevents these Attorneys General from using the sameproducts or similar cause of action for a lawsuitservices in a lower federal or other court. Previously, the Supreme Court has held that drug prohibition is a valid exercise of federal authority under the commerce clause; however, it has also held that an individual state itself is not required to adopt or enforce federal laws with which it disagrees.Canada.

In an effort to provide guidance to federal law enforcement, the US Department of Justice (the “DOJ”) has issued Guidance Regarding Marijuana Enforcement to all United States Attorneys in a memorandum from Deputy Attorney General David Ogden on October 19, 2009, in a memorandum from Deputy Attorney General James Cole on June 29, 2011 and in a memorandum from Deputy Attorney General James Cole on August 29, 2013. Each memorandum provides that the DOJ is committed to enforcement of the CSA but the DOJ is also committed to using its limited investigative and prosecutorial resources to address the most significant threats in the most effective, consistent and rational way.

The August 29, 2013 memorandum, known as the Cole Memo, provides updated guidance to federal prosecutors concerning marijuana enforcement in light of state laws legalizing medical and recreational marijuana possession in small amounts. The memorandumCole Memo sets forth certain enforcement priorities that are important to the federal government:

The DOJ has not historically devoted resources to prosecuting individuals whose conduct is limited to possession of small amounts of marijuana for use on private property but relied on state and local law enforcement to address marijuana activity. In the event the DOJ reverses stated policy and begins strict enforcement of the CSA in states that have laws legalizing medical marijuana and recreational marijuana in small amounts, there may be a direct and adverse impact to our revenue and profit.

In 2014, the US House of Representatives passed an amendment (the “Rohrabacher-Farr Amendment”) to the Commerce, Justice, Science, and Related Agencies Appropriations Bill, which funds the DOJ. The Rohrabacher-Farr Amendment prohibits the DOJ from using funds to prevent states with medical cannabis laws from implementing such laws. In August 2016, a Ninth Circuit federal appeals court ruled inUnited States v. McIntosh that the Rohrabacher-Farr Amendment bars the DOJ from spending funds on the prosecution of conduct that is allowed by state medical cannabis laws, provided that such conduct is in strict compliance with applicable state law. In March 2015, bipartisan legislation titled the Compassionate Access, Research Expansion, and Respect States Act (the “CARERS Act”) was introduced, proposing to allow states to regulate the medical use of cannabis by changing applicable federal law, including by reclassifying cannabis under the Controlled Substances Act to a Schedule II controlled substance and thereby changing the plant from a federally-criminalized substance to one that has recognized medical uses.

Although these developments have been met with a certain amount of optimism in the scientific community, the CARERS Act has not yet been adopted, and the Rohrabacher-Farr Amendment, being an amendment to an appropriations bill, must be renewed annually. The currently enacted Commerce, Justice, Science, and Related Agencies Act, which includes the Rohrabacher-Farr Amendment, is effective, by passage of a short-term continuing resolution, through April 28, 2017. The federal government could at any time change its enforcement priorities against the cannabis industry. Any change in enforcement priorities could render such operations unprofitable or even prohibit such operations.

The former Obama administration effectively stated that it is not an efficient use of resources to direct law federal law enforcement agencies to prosecute those lawfully abiding by state-designated laws allowing the use and distribution of medical marijuana. However, the new Trump administration could change this policy and decide to enforce the federal laws strongly. Any such change in the federal government’s enforcement of current federal laws could cause significant financial damage to us and our shareholders.

Litigation by States Affected by Marijuana Legalization

Due to variations in state law among states sharing borders, certain states which have not approved any legal sale of marijuana may seek to overturn laws legalizing cannabis use in neighboring states. For example, in December 2014, the attorneys general of Nebraska and Oklahoma filed a complaint with the U.S. Supreme Court against the state of Colorado arguing that the Supremacy Clause (Article VI of the Constitution) prohibits Colorado from passing laws that conflict with federal anti-drug laws and that Colorado’s laws are increasing marijuana trafficking in neighboring states that maintain marijuana bans, thereby putting pressure on such neighboring states’ criminal justice systems. In March 2016 the Supreme Court, voting 6-2, declined to hear this case, but there is no assurance that it will do so in the future. Additionally, nothing prevents these or other attorneys general from using the same or similar cause of action for a lawsuit in a lower federal or other court.

Previously, the Supreme Court has held that drug prohibition is a valid exercise of federal authority under the commerce clause; however, it has also held that an individual state itself is not required to adopt or enforce federal laws with which it disagrees. If the Supreme Court rules that a legal cannabis state’s legislation is unconstitutional, that could result in legal action against other states with laws legalizing medical and/or recreational cannabis use. Successful prosecution of such legal actions by non-marijuana states could have significant negative effects on our business.

Variations in state and local regulation and enforcement in states that have legalized cannabis that may restrict marijuana- relatedmarijuana-related activities, including activities related to cannabis, may negatively impact our revenue and profit.

Individual state laws do not always conform to the federal standard or to other states’ laws. A number of states have decriminalized marijuana to varying degrees, other states have created exemptions specifically for medical cannabis, and several have both decriminalization and medical laws. FourEight states and the District of Columbia have legalized the recreational use of cannabis. Variations exist among states that have legalized, decriminalized, or created medical marijuana exemptions. For example, Alaska and Colorado have limits on the number of marijuana plants that can be grown by an individual in the home. In most states the cultivation of marijuana for personal use continues to be prohibited except by those states that allow small-scale cultivation by the individual in possession of marijuana for medicinal purposes or that person’s caregiver. Active enforcement of state laws that prohibit personal cultivation of marijuana may indirectly and adversely affect revenue and profit of the Company.

It is possible that federal or state legislation could be enacted inWe and our customers may have difficulty accessing the future that would prohibit us, or potential customers, from sellingservice of banks, which may make it difficult to sell our products and if such legislation were enacted, our revenue could decline.services.

We are not aware of any federal or state regulation that regulatesFinancial transactions involving proceeds generated by cannabis-related conduct can form the sale of cultivation equipment to commercial cannabis growers. The extent to which the regulation of drug paraphernaliabasis for prosecution under the CSA is applicablefederal money laundering statutes, unlicensed money transmitter statute and the U.S. Bank Secrecy Act. Recent guidance issued by the Financial Crimes Enforcement Network, or FinCen, a division of the U.S. Department of the Treasury, clarifies how financial institutions can provide services to cannabis-related businesses consistent with their obligations under the Bank Secrecy Act. Furthermore, supplemental guidance from the DOJ directs federal prosecutors to consider the federal enforcement priorities enumerated in the Cole Memo when determining whether to charge institutions or individuals with any of the financial crimes described above based upon cannabis-related activity. Nevertheless, banks remain hesitant to offer banking services to cannabis-related businesses. Consequently, those businesses involved in the cannabis industry continue to encounter difficulty establishing banking relationships. Our inability to maintain our current bank accounts would make it difficult for us to operate our business, increase our operating costs, and the sale ofpose additional operational, logistical and security challenges and could result in our product is found in the definition of drug paraphernalia. Our products are designed for commercial cannabis and agricultural use in accordance with state law.inability to implement our business plan.

Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern.

Our auditors have included a “going concern” provision in their opinion on our financial statements, expressing substantial doubt that we can continue as an ongoing business for the next twelve months. Our financial statements do not include any adjustments that may result from the outcome of this uncertainty. If we are unable to successfully raise the capital we need we may need to reduce the scope of our business to fully satisfy our future short-term liquidity requirements. If we cannot raise additional capital or reduce the scope of our business, we may be otherwise unable to achieve our goals or continue our operations. While we believe that we will be able to raise the capital we need to continue our operations, there can be no assurances that we will be successful in these efforts or will be able to resolve our liquidity issues or eliminate our operating losses.

Our inability to effectively manage our growth could harm our business and materially and adversely affect our operating results and financial condition.

Our strategy envisions growing our business. We plan to expand our product, sales, administrative and marketing operations. Any growth in or expansion of our business is likely to continue to place a strain on our management and administrative resources, infrastructure and systems. As with other growing businesses, we expect that we will need to further refine and expand our business development capabilities, our systems and processes and our access to financing sources. We also will need to hire, train, supervise, and manage new employees. These processes are time consuming and expensive, will increase management responsibilities and will divert management attention. We cannot assure that we will be able to:

Our inability or failure to manage our growth and expansion effectively could harm our business and materially and adversely affect our operating results and financial condition.

Our operating results may fluctuate significantly based on customer acceptance of our products. As a result, period-to-period comparisons of our results of operations are unlikely to provide a good indication of our future performance.

Management expects that we will experience substantial variations in our net sales and operating results from quarter to quarter due to customer acceptance of our products. If customers don’tdo not accept our products, our sales and revenue will decline, resulting in a reduction in our operating income or possible increase in losses.

If we do not successfully generate additional products and services, or if such products and services are developed but not successfully commercialized, we could lose revenue opportunities.

Our future success depends, in part, on our ability to expand our product and service offerings. To that end we have engaged in the process of identifying new product opportunities, such as our reflector and hybrid buildingHybrid Building to provide additional products and related services to our customers. The processes of identifying and commercializing new products is complex and uncertain, and if we fail to accurately predict customers’ changing needs and emerging technological trends our business could be harmed. We have already and may have to continue to commit significant resources to commercializing new products before knowing whether our investments will result in products the market will accept. Furthermore, we may not execute successfully on commercializing those products because of errors in product planning or timing, technical hurdles that we fail to overcome in a timely fashion, or a lack of appropriate resources. This could result in competitors providing those solutions before we do and a reduction in net sales and earnings.

The success of new products depends on several factors, including proper new product definition, timely completion, and introduction of these products, differentiation of new products from those of our competitors, and market acceptance of these products. There can be no assurance that we will successfully identify additional new product opportunities, develop and bring new products to market in a timely manner, or achieve market acceptance of our products or that products and technologies developed by others will not render our products or technologies obsolete or noncompetitive.

Our future success depends on our ability to grow and expand our customer base. Our failure to achieve such growth or expansion could materially harm our business.

To date, our revenue growth has been derived from the sale of our products and services. Our success and the planned growth and expansion of our business depend on us achieving greater and broader acceptance of our products and services and expanding our commercial customer base. There can be no assurance that customers will purchase orour services ouror products or that we will continue to expand our customer base. If we are unable to effectively market or expand our product and service offerings, we will be unable to grow and expand our business or implement our business strategy. This could materially impair our ability to increase sales and revenue and materially and adversely affect our margins, which could harm our business and cause our stock price to decline.

Our suppliers could fail to fulfill our orders for parts used to assemble our products, which would disrupt our business, increase our costs, harm our reputation, and potentially cause us to lose our market.

We depend on third party suppliers around the world, including in The People’s Republic of China, for materials used to assemble our products. These suppliers could fail to produce products to our specifications or in a workmanlike manner and may not deliver the material or products on a timely basis. Our suppliers may also have to obtain inventories of the necessary parts and tools for production. Any change in our suppliers’ approach to resolving production issues could disrupt our ability to fulfill orders and could also disrupt our business due to delays in finding new suppliers, providing specifications and testing initial production. Such disruptions in our business and/or delays in fulfilling orders could harm our reputation and could potentially cause us to lose our market.

Our inability to effectively protect our intellectual property would adversely affect our ability to compete effectively, our revenue, our financial condition, and our results of operations.

We may be unable to obtain intellectual property rights to effectively protect our branding, products, and other intangible assets. Our ability to compete effectively may be affected by the nature and breadth of our intellectual property rights. While we intend to defend against any threats to our intellectual property rights, there can be no assurance that any such actions will adequately protect our interests. If we are unable to secure intellectual property rights to effectively protect our branding, products, and other intangible assets, our revenue and earnings, financial condition, or results of operations could be adversely affected.

We also rely on non-disclosure and non-competition agreements to protect portions of our intellectual property portfolio. There can be no assurance that these agreements will not be breached, that we will have adequate remedies for any breach, that third parties will not otherwise gain access to our trade secrets or proprietary knowledge, or that third parties will not independently develop competitive products with similar intellectual property.

Our industry is highly competitive and we have less capital and resources than many of our competitors, which may give them an advantage in developing and marketing products similar to ours or make our products obsolete.

We are involved in a highly competitive industry where we compete with various other HVAC and dehumidification manufacturers who offer products similar to the products we sell. These competitors may have far greater resources than we do, giving our competitors an advantage in developing and marketing products similar to ours or products that make our products obsolete. While we believe we are better equipped to customize products for the cannabis market and advise growers on appropriate products to maximize crop yield as compared to traditional HVAC and dehumidification manufacturers, there can be no assurance that we will be able to successfully compete against these other manufacturers.

We will be required to attract and retain top quality talent to compete in the marketplace.

We believe our future growth and success will depend in part on our ability to attract and retain highly skilled managerial, product development, sales and marketing, and finance personnel. There can be no assurance of success in attracting and retaining such personnel. Shortages in qualified personnel could limit our ability to increase sales of existing products and services and launch new product and service offerings.

The market price of our common stock may be volatile and may be affected by market conditions beyond our control. The market price of our common stock is subject to significant fluctuations in response to, among other factors:

In addition, if the market for stocks in our industry, or the stock market in general, experiences a loss of investor confidence, the market price of our common stock could decline for reasons unrelated to our business, financial condition, or results of operations. If any of the foregoing occurs, it could cause the price of our common stock to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and a distraction to our Board of Directors and management.

The application of the “penny stock” rules could adversely affect the market price of our common shares and increase your transaction costs to sell those shares.

The SEC has adopted Rule 3a51-1, which establishes the definition of a “penny stock,” for the purposes relevant to us, as any equity security that has a market price of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, Rule 15g-9 requires:

The broker or dealer must also deliver, prior to any transaction in a penny stock, a disclosure schedule prescribed by the SEC relating to the penny stock market, which, in highlight form:

Generally, brokers may be less willing to execute transactions in securities subject to the “penny stock” rules. This may make it more difficult for investors to dispose of our common stock and cause a decline in the market value of our stock.

If it were determined that our spin-off of Trebor Resource Management Group, Inc. in March 2014 violated federal or state securities laws, we could incur monetary damages, fines or other damages that could have a material adverse effect on our financial condition and prospects.

As we previously reported, effective March 25, 2014, we effected the issuance of a dividend/spin-off of all of our ownership our wholly owned subsidiary, Trebor Resource Management Group, Inc. (“Trebor”), to our shareholders, resulting in Trebor becoming a separate entity (the “Spin-off”). The issuance of Trebor stock was completed on a one-for-one basis to our shareholders of record on March 21, 2014.

Under Staff Legal Bulletin No. 4 promulgated by the Division of Corporation Finance (the “Division”) of the SEC, the Division expressed its view that the shares of a subsidiary spun off from a reporting company are not required to be registered under the Securities Act of 1933, as amended (the “Securities Act”) when certain conditions are met. Although we intended to comply with the guidance set forth in Staff Legal Bulletin No. 4, we inadvertently failed to follow all of the steps necessary to rely on this guidance.

If it were determined that the Spin-off did not satisfy the conditions for an exemption from registration, the SEC and relevant state regulators could impose monetary fines or other sanctions as provided under relevant federal and state securities laws. Such regulators could also require us to make a rescission offer, which is an offer to repurchase the securities, to the holders of Trebor shares. This could also give certain current and former holders of the Trebor shares a private right of action to seek a rescission remedy under Section 12(a)(2) of the Securities Act. In general, this remedy allows a successful claimant to sell its shares back to the parent company in return for their original investment.

We are unable to quantify the extent of any monetary damages that we might incur if monetary fines were imposed, rescission were required, or one or more other claims were successful. As of the date of this filing, we are not aware of any pending or threatened claims that the Spin-off violated any federal or state securities laws, and we do not believe that assertion of such claims by any current or former holders of the Trebor shares is probable. However, there can be no assurance that any such claim will not be asserted in the future or that the claimant in any such action will not prevail. The possibility that such claims may be asserted in the future will continue until the expiration of the applicable federal and state statutes of limitations, which generally vary from one to three years from the date of sale. Claims under the antifraud provisions of the federal securities laws, if relevant, would generally have to be brought within two years of discovery, but not more than five years after occurrence.

Rule 144 Related Risk.contains risks for certain shareholders.

Pursuant to SEC Rule 144 promulgated under the Securities Act,, a person who has beneficially owned restricted shares of our common stock for at least six months would be entitled to sell their securities provided that: (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding a sale, (ii) we are subject to the Exchange Act periodic reporting requirements for at least 90 days before the sale and (iii) if the sale occurs prior to satisfaction of a one-year holding period, we providehave provided the public with current information at the time of sale.

Persons who have beneficially owned restricted shares of our common stock for at least six months but who are our affiliates at the time of, or at any time during the three months preceding a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of either of the following:

Provided, in each case, we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale. Such sales by affiliates must also comply with the manner of sale, current public information, and notice provisions of Rule 144.

Overview

Surna develops, designs, and distributes cultivation technologies for controlled environment agriculture (“CEA”). The Company’s customers include state-regulated cannabis cultivation facilities as well as traditional indoor agricultural facilities, including organic herb and vegetable producers. Surna’s technologies include a comprehensive line of optimized lighting, environmental control, air sanitation, and cultivation facilities. These technologies are designed to meet the specific environmental conditions required for CEA and to dramatically reduce energy and water consumption.

In addition, Surna offers mechanical design services specific to hydronic cooling, including mechanical equipment and piping design.

Recent Developments

On January 8, 2015, the Company agreed to acquire 66% of the total membership interests in Agrisoft Development Group, LLC (“Agrisoft”). In connection with the purchase agreement the Company advanced a total of $260,000 through March 31, 2015, and secured repayment against certain of Agrisoft’s assets. Prior to the closing of the transaction, however, Kind Agrisoft, LLC (“Kind Agrisoft”), with the Company’s consent, agreed to purchase 100% of Agrisoft’s assets. On June 23, 2015, in exchange for the Company’s consent to its asset purchase agreement, Kind Agrisoft guaranteed repayment of the Company’s advances to Agrisoft, the balance of which was then $272,217 plus annual interest of eight percent (8%), and it granted to the Company a secured interest in its accounts receivable and intellectual property to further guarantee such payment. Furthermore, Kind Agrisoft is obligated to make additional ongoing payments to the Company in the form of a 1% quarterly royalty on EBITDA (earnings before interest, taxes, depreciation, and amortization) until Kind Agrisoft’s total payments to the Company (including payments under the Note and royalty on EBITDA) reach $600,000. The Company abandoned this acquisition and the note was paid-off in January 2017.

On February 24, 2015, Tom Bollich submitted his resignation as President, Chief Executive Officer, Chairman of the Board, and a member of the Board of Directors of the Company (“Board”), effective April 15, 2015.

He co-founded Hydro Innovations in 2007 and served as its Chief Executive Officer until its acquisition by the Company in July 2014.

As further described in Note 10, in 2014on October 31, 2016, the Company engagedbegan private negotiations with certain holders of certain 10% convertible promissory notes (the “Original Notes”) and warrants (the “Original Warrants” and together with the Original Notes, the “Original Securities”) with a placement agent forview to amending and converting the saleOriginal Notes and amending the terms of up to $3,000,000the Original Warrants.

The Original Securities were issued as part of “Securities” as defined (“Series 2”). The Company raised $1,625,000 in 2014 and $911,250 in the first quarter of 2015.

The Original Notes mature and become payable two years from issuance.

As of February 20, 2017, the Company has entered into Note Conversion and Warrant Amendment Agreements (each, an “Agreement” and together, the “Agreements”) with each of 48 holders, to: (i) amend the Original Note (each an “Amended Note”) to reduce the conversion price of such holder’s Original Note and simultaneously cause the conversion of the outstanding amount under such Original Note into shares of Common Stock of the Company (“Conversion Shares”) with the exception of agreements with three holders which provide for the payment of the principal amount in cash and the interest outstanding in stock and a further three agreements in which a cash sum was negotiated to pay the outstanding note in full; and (ii) reduce the exercise price of the Original Warrant (each, an “Amended Warrant” and together with an Amended Note, the “Amendments”) in all except three Agreements. Each Agreement has been privately negotiated so the terms vary. Pursuant to the Agreements, the Original Notes have been amended to reflect a reduced conversion price per share between $0.09 and $0.22. Additionally, pursuant to the Agreements,certain Original Warrants have been amended to reflect a reduced exercise price per share between $0.30 and $0.35, with the exception of the first Agreement signed which amended certain Original Warrants to reflect a reduced exercise price of $0.15 per share.

Results of Operations

Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015

Revenue for the year ended December 31, 2016 decreased by 4% to $7,580,000 for the year ended December 31, 2016 as compared to $7,865,000 for 2015. A significant portion of our revenues for 2015 were derived from growers in the State of Nevada (legalized cannabis in 2014), which peaked in the third quarter of 2015. As our sales declined slightly from 2015 to 2016, our contractual sales commitments have been increasing. The sales amounts that we had under contract but which were not yet completed have increased year over year from $1,423,000 at December 31, 2015 to $2,646,000 at December 31, 2016.

Our contractual sales commitments increased during 2016 due to our customers having experienced increased delays in completing the construction of their facilities to accept their product. Our contractual sales cannot be canceled by our customers. Initially our sales contracts were dependent upon our customers’ ability to secure, license and build their growing facilities and thus our revenue recognition was dependent upon shipping and our customers’ ability to receive the product. We have seen an increased delay in the time frames in which our customers have been able to receive the product, most likely related to the increasing size of our projects. This factor has slowed our revenue recognition and increased our contractual sales commitments.

Since October 2016, all of our sales contracts have been freight-on board shipping (“FOB Shipping”). This removes any dependencies on our revenue recognition being tied to a customer’s ability to receive product. The substantial increase in revenue for fiscal year 2015 compared to the prior year resulted from Hydro contributing twelve months of revenue to our results in fiscal year 2015, while Hydro’s operations were a part of Surna for only five months in fiscal year 2014. Additional increases, and sustained, revenues from 2014 to 2016 are attributable to progress and ongoing legal and regulatory developments in an increasing number of states that permit and regulate cannabis cultivation and use for medical or recreational purposes. Our current and future revenue plan is dependent on the continued and increasing legality of the cannabis industry and our ability to effectively market our indoor agriculture products to this key segment as well as expand our reach to other markets.

Cost of revenue decreased by 24% to $5,276,000 for the year ended December 31, 2016 as compared to $6,924,000 for the year ended December 31, 2015. The gross margin for the year ended December 31, 2016 increased by 18% to 30% as compared to 12% for the year ended December 31, 2015 due to (i) negotiation of favorable pricing with key suppliers or sourcing new suppliers, (ii) a sales mix that consisted more of high margin products and (iii) reduced spending on installation projects, as we no longer provide installation services. These decreases are offset by a one-time charge in the year ended December 31, 2016 of approximately $530,000 for a warranty expense.

Operating expenses decreased by 30% to $2,837,000 for the year ended December 31, 2016 as compared to $4,055,000 for the year ended December 31, 2015. We have decreased advertising and marketing expenses by 52% from $310,000 for 2015 to $150,000 for 2016 due to a heavier emphasis on advertising in the prior year and a focus on reigning in costs in 2016. We decreased product development costs by 51% from $708,000 in 2015 to $349,000 in 2016 due to the product life cycle of the Surna reflector product, which has moved from development stage in the first quarter of 2015 to production stage in the first quarter of 2016. Also in 2015, we had additional cost of approximately $150,000 related to the development of the Surna Hybrid Building, which we introduced at the Marijuana Daily Conference in November 2016. We decreased general and administrative expenses by 23% from $3,038,000 in 2015 to $2,338,000 in 2016 due to reductions in personnel cost of approximately $200,000 as well as a focus on cost containment related to professional fees of approximately $250,000. We also reduced selling expenses and travel by approximately $150,000.

Other expenses have increased by 26% to $2,740,000 for the year ended December 31, 2016 from approximately $2,182,000 for the year ended December 31, 2015. The change is attributable to (i) a decrease in amortization of debt discounts and interest expense, (ii) the conversion of certain convertible promissory notes converted in the first quarter and second quarter of 2016; (iii) the loss on the change in derivative liabilities; and (iv) the loss due to the extinguishment of debt in the fourth quarter of 2016.

As a result of our decrease in cost of revenue and operating expenses, we reduced our net loss to $3,273,000 for the year ended December 31, 2016 as compared to $5,296,000 for the year ended December 31, 2015.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Revenue for the year ended December 31, 2015 was $7,865,243 as compared to $1,838,912 (328% growth) for the year ended December 31, 2014. The substantial increase in revenue for fiscal year 2015 compared to the prior year resulted from Hydro contributing twelve months of revenue to our results in fiscal year 2015, while Hydro’s operations were a part of Surna for only five months in fiscal year 2014. Additional increases in revenues are attributable to progress and ongoing legal and regulatory developments in an increasing number of states that permit and regulate cannabis cultivation and use for medical or recreational purposes. Our current and future revenue plan is dependent on the continued and increasing legality of the cannabis industry and our ability to effectively market our indoor agriculture products to this key segment as well as expand our reach to other markets.

Cost of revenue for the year ended December 31, 2015 was $6,924,402 as compared to $1,534,918 (351% increase) for the year ended December 31, 2014. Increases are due in large part to increases in sales as well as the fact that Hydro operated as a Surna subsidiary for twelve months during fiscal year 2015 and only five months during fiscal year 2014. Cost of revenue increased at a slightly higher rate than revenue due in part to costs related to installation contracts that Surna began in the second half of 2014. Surna has since trained several traditional HVAC installation companies on the Surna system and will cease installation and focus on core competencies in 2016. Surna saw gross margin percentages erode to 12% from 17% due primarily to the reduced margins from the installation business as well as higher manufacturing costs.

Operating expenses were $4,054,684 compared to $3,496,458 for the year ended December 31, 2015 and 2014, respectively. Although operating expenses increased 16% year over year, such costs declined as percentage of revenue to 52% in 2015 from 190% in 2014. The increase is attributable to the more than doubling of product development costs to $707,517 from $319,430 as Surna makes key investments in its Hybrid building and lighting technologies. The 29% increase in advertising and marketing expenses to $309,620 from $240,784 is due in part to expenditures on potential customer tours at facilities that are now running Surna climate control systems. Additionally, now that more states have legal cannabis Surna is covering a wider geographic area with marketing events and conferences. The 3% increase in selling, general and administrative expenses to $3,037,547 from $2,936,244 for the year ended December 31, 2015 compared to the year ended December 31, 2014 represents investments in administrative staff and support to manage the more than tripling of transaction volumes. Selling, general and administrative expenses are primarily sales and marketing personnel costs as well as corporate, legal, and accounting expenses.

We incurred net other expenses of $2,182,179 for the year ended December 31, 2015 compared to net other income of $218,266 for the year ended December 31, 2014. This change largely resulted from $2,220,115 of amortization of debt discounts as well as greater interest expense, both in connection with convertible promissory notes issued during fiscal years 2015 and 2014.

Surna experienced very high growth in the second half of the year and experienced cash shortages as the Company increased inventory purchases to meet the new rates of demand. In order to meet the immediate cash requirements at that time Surna took on some debt at disadvantageous terms. Surna management is focused on improving margins by reducing costs and optimizing pricing so that reliance on outside debt is limited in the future.

We reported no discontinued operations for fiscal year 2015, while we incurred a loss of $17,771 from discontinued operations in connection with the sale of Surna Media, Inc. and its affiliates in fiscal year 2014.

Overall, we realized a net loss of $5,296,022 for the year ended December 31, 2015 as compared to $2,991,969 for the year ended December 31, 2014.

Liquidity and Capital Resources

During fiscal years 2015 and 2014,the year ended December 31, 2016, our primary source of liquidity was cash provided byfrom operating activities as compared to prior years where our primary source of liquidity was from financing activities. Presently, operating activities do not generate adequate amounts of cashThis significant change in liquidity is due primarily to meet the Company’s cash needs for working capital requirements.effort in reducing the cost of goods sold and general and administrative expenses. The following summariessummarizes our cash flows:flows for the years ended December 31,:

WeAs a result of our decrease in cost of revenue and operating expenses, as described above, we used less cash in operating activities during fiscalthe year 2015ended December 31, 2016 as compared to fiscal year 2014, primarily as a result of changes in customer payment policies and larger payable balances related to a build up of inventory to meet increased customer demand. Cost saving measures implemented in the second half of the year contributed to cost containment. These improvements were offset by a greater net loss due primarily to the cost of financing.December 31, 2015.

As of December 31, 20152016 and 2014,2015, our total assets were $3,102,734$2,118,000 and $2,321,292,$3,103,000, respectively, and our total liabilities were $5,950,031$4,229,000 and $3,205,044,$5,950,000, respectively. We had a deficit in working capital of $3,020,231 and $779,387 asAs of December 31, 20152016 and 2014, respectively, primarily resulting from significantly larger debt balances.2105, we had working capital deficits of approximately of $2,860,000 and $3,020,000, respectively.

We reported net losses of $5,296,022$3,273,000 and $2,991,969$5,296,000 for the fiscal years ended December 31, 20152016 and 2014,2015, respectively.

During the yearyears ended December 31, 2016 and 2015, we raised a total of $0 and $1,781,250 in connection with issuances of three series of convertible promissory notes. During the year ended 2014, we raised $2,961,783 in connection with issuances of two series of convertible promissory notes.

In March 2017, the Company complete a private placement offering of its common stock for total proceeds of $2,685,000.

Cash Requirements

Our ability to fund our growth and meet our obligations on a timely basis is dependent on our ability to match our available financial resources to our growth strategy, which includes acquisitions for cash or a combination of cash and debt. The decisions we make with regard to acquisitions drive the level of capital required and the level of our financial obligations.

If we are unable to generate cash flow from operations and successfully raise sufficient additional capital through future debt and equity financings or strategic and collaborative ventures with potential partners, we would likely have to reduce the size and scope of our acquisitions. During the year ended 2014, the Company raised a total of $2,961,783 in connection with two series of convertible promissory note issuances. During the year ended 2015, the Company raised another $1,781,250 in connection with three series of convertible promissory notes.operations.

We have suffered recurring losses from operations. The continuation of our companyCompany is dependent upon our companyCompany attaining and maintaining profitable operations and raising additional capital as needed. In this regard, we have raised additional capital through equity offerings and loan transactions, and, in the short term, will seek to raise additional capital in such manners to fund our operations. Our officers and shareholders have not made any written or oral agreement to provide us additional financing. There can be no assurance that we will be able to continue to raise capital on terms and conditions that are deemed acceptable to us.

Inflation

In the opinion of management, inflation has not and will not have a material effect on our operations in the immediate future. Management will continue to monitor inflation and evaluate the possible future effects of inflation on our business and operations.

Contractual Payment Obligations

We have obligations under notes payable and a non-cancelable operating lease, and a vehicle loan.lease. As of December 31, 2015,2016, our contractual obligations are as follows:

As described above, we entered into the several promissory notes pursuant to which we have an aggregate principal balance of $3,537,966 as of December 31, 2015. As of the date of this filing, the outstanding principal balance was $3,108,540.debt obligations (including interest) were converted into the Company’s common stock or paid in in cash.

In connection with its acquisition of Hydro in July 2014, theThe Company assumedholds a lease agreement for its manufacturing and office space consisting of approximately 18,000 square feet. The lease term extends through April 1, 2017. The Company is in the process of negotiating a 90-day extension for our expired lease. We are in the process of evaluating our future office and manufacturing facilities. Unless earlier renewed, thewarehouse needs, so we plan to continue with 90-day extensions under our expired lease agreement will terminate in September 2016.until we determine our office and warehouse requirements.

During the year ended December 31, 2014, the Company financed a vehicle. The original balance of the loan was $47,286. The loan bears interest at the rate of 3.99% and is payable in installments of $872 per month for 60 months.

Off Balance Sheet Arrangements

Under CommissionSEC regulations, we are required to disclose our off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, such as changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors. As of December 31, 2015,2016, we have no off-balance sheet arrangements.

Going Concern

The Company’s independent registered public auditor’s report accompanying our December 31, 20152016 and 20142015 audited financial statements contains an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. The financial statements have been prepared “assumingassuming that the Company will continue as a going concern.” Our ability to continue as a going concern is dependent on raising additional capital to fund our operations and ultimately on generating future profitable operations. There can be no assurance that we will be able to raise sufficient additional capital or eventually have positive cash flow from operations to address all of our cash flow needs. If we are not able to find alternative sources of cash or generate positive cash flow from operations, our business and shareholders will be materially and adversely affected.

Critical Accounting Policies

The discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America. Certain accounting policies and estimates are particularly important to the understanding of our financial position and results of operations and require the application of significant judgment by our management or can be materially affected by changes from period to period in economic factors or conditions that are outside of our control. As a result, they are subject to an inherent degree of uncertainty. In applying these policies, management uses their judgment to determine the appropriate assumptions to be used in the determination of certain estimates. Those estimates are based on our historical operations, our future business plans and projected financial results, the terms of existing contracts, observance of trends in the industry, information provided by our customers and information available from other outside sources, as appropriate. For information regarding the Company’s critical accounting policies as well as recent accounting pronouncements, see Note 1 to the consolidated financial statements.

Concentration of Credit Risk

Financial instruments that potentially subject Surna to concentration of credit risk consist of cash and accounts receivable. Under Section 343 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, for the two-year period of January 1, 20142015 through December 31, 2015,2016, cash balances in noninterest-bearing transaction accounts at all FDIC-insured depository institutions are provided temporary unlimited deposit insurance coverage. As of December 31, 2015,2016, cash balances in interest-bearing accounts are $325,043.were approximately $280,000.

Two customers accounted for 14% and 10%, respectively, of the Company’s revenue for the year ended December 31, 2016. One customer accounted for 10% of the Company’s revenue for the year ended December 31, 2015. One customer accounted for 11%

The Company’s accounts receivable from two customers make up 39% and 29% of the Company’s revenue for the year endedtotal balance as of December 31, 2014.

2016. The Company’s accounts receivable from four customers made up 89% of the total balance as of December 31, 2015. The Company’s accounts receivable from two customers made up 58% of the total balance as of December 31, 2014.

The Company purchased 61% of it cost of revenue from four vendors during the year ended December 31, 2015. The Company purchased 75% of it cost of revenue from four vendors during the year ended December 31, 2014. The Company believes that, in the event that its primary vendors are unable or unwilling to continue to sell its products, there are alternative vendors at comparable prices.

Trends, Events, and Uncertainties

Development of new technologies or product solutions is, by its nature, unpredictable. Although we will undertake development efforts with commercially reasonable diligence, there can be no assurance that we will have adequate capital to develop our technology or products to the extent needed to create future sales to sustain our operations.

We cannotNo assurance can be assuredprovided that our technology or products will be adopted, that we will ever earn revenue sufficient to support our operations, or that we will ever be profitable. Furthermore, since we have no committed source of financing, we cannot be assuredcan provide no assurance that we will be able to raise money as and when we need it to continue our operations. If we cannot raise funds as and when we need them, we may be required to severely curtail, or even to cease, our operations.

Other than as discussed above and elsewhere in this Annual Report on Form 10-K, we are not aware of any trends, events, or uncertainties that are likely to have a material effect on our financial condition.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management conducted an evaluation, with the participation of our Chief Executive Officer and our ChiefPrincipal Financial and Accounting Officer of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this annual report on Form 10-K. Based upon that evaluation, our Chief Operating Officer and Chief Financial Officer concluded that as a result of the material weakness in our internal control over financial reporting described below, our disclosure controls and procedures were not effective as of December 31, 2015.2016.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for the preparation of our financial statements and related information. Management uses its best judgment to ensure that the financial statements present fairly, in material respects, our financial position and results of operations in conformity with generally accepted accounting principles.

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in the Exchange Act. These internal controls are designed to provide reasonable assurance that the reported financial information is presented fairly, that disclosures are adequate and that the judgments inherent in the preparation of financial statements are reasonable. There are inherent limitations in the effectiveness of any system of internal controls including the possibility of human error and overriding of controls. Consequently, an effective internal control system can only provide reasonable, not absolute, assurance with respect to reporting financial information.

Our internal control over financial reporting includes policies and procedures that: (i) pertain to maintaining records that, in reasonable detail, accurately and fairly reflect our transactions; (ii) provide reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles and that the receipts and expenditures of company assets are made in accordance with our management and directors authorization; and (iii) provide reasonable assurance regarding the prevention of or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on our financial statements.

Under the supervision of management, including our Chief Executive Officer and our ChiefPrincipal Financial and Accounting Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) published in 2013 and subsequent guidance prepared by COSO specifically for smaller public companies. Based on that evaluation, our management concluded that our internal control over financial reporting was not effective as of December 31, 20152016 for the reasons discussed below.

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 the annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Management identified the following material weakness in its assessment of the effectiveness of internal control over financial reporting as of December 31, 2015:2016:

The Company did not maintain effective controls over certain aspects of the financial reporting process because we lacked a sufficient complement of personnel with a level of accounting expertise and an adequate supervisory review structure that is commensurate with our financial reporting requirements. In addition, there was inadequate segregation of duties due to the limitation on the number of our accounting personnel.

We intend to take appropriate and reasonable steps to make the necessary improvements to remediate these deficiencies. However, due to our size and nature, segregation of all conflicting duties has not always been possible and may not be economically feasible.

Our management, including our Chief Executive Officer and our ChiefPrincipal Financial and Accounting Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.

The material weaknesses in internal control over financial reporting as of December 31, 20152016 remain unchanged from December 31, 2014.2015. Management believes that the material weaknesses set forth above did not have an effect on our financial reporting for the year ended December 31, 2015.2016. Yet, we are committed to continuing to improve our financial organization. As part of this commitment, during 2015, we added an independent director to our Board. Subject to the availability of sufficient funds during 20162017 to expand our accounting staff, we also expect to create a position to segregate duties consistent with control objectives and will increase our personnel resources, if necessary, by hiring independent third parties or consultants to provide expert advice as needed.

We will continue to monitor and evaluate the effectiveness of our internal control over financial reporting on an ongoing basis and are committed to taking further action and implementing additional enhancements or improvements, as necessary and as funds allow. We do not, however, expect that the material weaknesses in our disclosure controls will be remediated until such time as we have improved our internal control over financial reporting.

This annual report on Form 10-K does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to rules of the CommissionSEC that permit us to provide only management’s report in this annual report on Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes identified in connection with our internal control over financial reporting during the quarter ended December 31, 2015,2016, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Committees of our Board of Directors

Our securities are not quoted on an exchange that has requirements that a majority of our Board members be independent and we are not currently otherwise subject to any law, rule or regulation requiring that all or any portion of our Board of Directors include “independent” directors, nor are we required to establish or maintain an audit committee or other committee of our Board.

Nevertheless, we have a compensation committee, which is chaired by Mr. Paxhia and on which Ms. Keen also serves. The Board does not have standing audit or nominating committees, nor does it have an audit committee financial expert. The Board does not believe these committees are necessary based on the size of the Company, the current levels of compensation to corporate officers, and the concentration of ownership of our securities with members of our Board. The Board will consider establishing audit and nominating committees at the appropriate time.

The entire Board participates in the consideration of compensation issues and of director nominees, with specific input and guidance from the members of our compensation committee. Candidates for director nominees are reviewed in the context of the current composition of the Board and the Company’s operating requirements and the long-term interests of its shareholders. In conducting this assessment, the Board considers skills, diversity, age, and such other factors as it deems appropriate given the current needs of the Board and the Company, to maintain a balance of knowledge, experience, and capability.

The Board’s process for identifying and evaluating nominees for director, including nominees recommended by shareholders, will involveinvolves compiling names of potentially eligible candidates, conducting background and reference checks, conducting interviews with the candidate and others (as schedules permit), meeting to consider and approve the final candidates and, as appropriate, preparing an analysis with regard to particular recommended candidates.
