Oil and natural gas exploration, production and related operations and activities are subject to extensive rules and regulations promulgated by federal, state and local governmental agencies. Failure to comply with such rules and regulations can result in substantial penalties. Because such rules and regulations are frequently amended or reinterpreted, we are unable to predict the future cost or impact of complying with such laws. Although the regulatory burden on the oil and natural gas industry increases our cost of doing business and, consequently, affects our profitability, these burdens generally do not affect us any differently or to any greater or lesser extent than they affect others in our industry with similar types, quantities and locations of production.

We maintain insurance through our operators of various types to cover our operations with policy limits and retention liability customary in the industry. We believe the coverage and types of insurance are adequate. The occurrence of a significant adverse event, the risks of which are not fully covered by insurance, could have a material adverse effect on our financial condition and results of operations. We cannot give any assurances that we will be able to maintain adequate insurance in the future at rates we consider reasonable.

As is customary in the oil and natural gas industry, we perform a minimal title investigation before acquiring undeveloped properties. A title opinion is obtained prior to the commencement of drilling operations on such properties. These title investigations and title opinions, while consistent with industry standards, may not reveal existing or potential title defects, encumbrances or adverse claims as we are subject from time to time to claims or disputes regarding title to properties. Although we have title to developed acreage examined prior to the acquisition in those cases in which the economic significance of the acreage justifies the cost, there can be no assurance that losses will not result from title defect or defects in the assignment of leasehold rights. Our properties are subject to customary royalty interests, liens incident to operating agreements, liens for current taxes and other burdens that we believe do not materially interfere with the use of or affect the value of such properties.

Other than our directors and officers, as of December 31, 2012, we do not have employees.

Transfer Agent

On December 28, 2007, the Company appointed Securities Transfer Corporation as the Transfer Agent to handle securities transactions for the Company. The address for Securities Transfer Corporation is 2591 Dallas Parkway, Suite 102, Frisco, Texas 75034.

The public may read and copy any materials the Company files with the SEC at the SEC's Public Reference Room at 100 F Street, NE, Washington, D.C. 20549, on official business days during the hours of 10 a.m. to 3 p.m. The public may obtain information on the operation of the Public Reference Room by calling the Commission at 1-800-SEC-0330 or through internet access via the EDGAR reporting system. Additional information is available at our website at www.regt.co.

There are many factors that affect our business, some of which are beyond our control. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. The nature of our business activities further subjects us to certain hazards and risks. One should carefully consider the following risk factors, in addition to the other information set forth in this Report, before investing in shares of our common stock. Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock. Some information in this report may contain "forward-looking" statements that discuss future expectations of our financial condition and results of operation. The risk factors noted in this section and other factors could cause our actual results to differ from those contained in any forward-looking statements. We undertake no obligation to update a forward-looking statement to reflect subsequent events, changed circumstances, or the occurrence of unanticipated events which included, among others, the following:

• difficult and adverse conditions in the domestic and global economies;
• changes in domestic and global demand for oil and natural gas;
• volatility in the prices we receive for our oil and natural gas;
• the effects of government regulation, permitting and other legalities;
• future developments with respect to the reserves on our properties;
• uncertainties about the estimates of our oil and natural gas reserves;
• our ability to increase our production through development;
• drilling and other operating risks;
• the availability of equipment, such as drilling rigs and pipelines; and
• changes in our drilling plans, related budgets and liquidity.

We caution you that these forward-looking statements are subject to all of the risks and uncertainties incident to the exploration for and development, production and marketing of oil and natural gas. These risks include, but are not limited to:

• the possibility of unsuccessful exploration and development drilling activities;
• our ability to replace and sustain production;
• the availability of capital on economic terms to fund our capital expenditures and acquisitions;
• our level of indebtedness;
• the impact of the past or future economic recessions on our business operations, financial condition and ability to raise capital;
• the ability of financial counterparties to perform or fulfill their obligations under existing agreements;
• the uncertainty inherent in estimating proved oil and natural gas reserves and in projecting future rates of production and timing of development expenditures;
• hurricanes and other weather conditions;
• lack of availability of goods and services;
• regulatory and environmental risks associated with drilling and production activities; and
• the other risks described in this Form 10-K.

Reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data and the interpretation of that data by petroleum engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, these revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates are generally different from the quantities of oil and natural gas that are ultimately recovered. Other unknown or unpredictable factors may cause actual results to differ materially from those projected by the forward-looking statements. Unless otherwise required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. We urge readers to review and consider disclosures we make in this and other reports. See in particular our reports on Forms 10-K, 10-Q and 8-K subsequently filed from time to time with the SEC.

Our limited operating history makes it difficult for us to evaluate our future business prospects and make decisions based on those estimates of our future performance. Although our management team has been engaged in technology development for an extended period of time, we did not begin operations of our current business concept until recently. Therefore, it is difficult to forecast our future results based upon our historical data. Reliance on the historical results of our acquisition targets may not be representative of the results we will achieve, particularly in our combined form. Because of the uncertainties related to our lack of historical operations, we may be hindered in our ability to anticipate and timely adapt to increases or decreases in income or expenses. If we make poor budgetary decisions as a result of unreliable historical data, we could be less profitable or incur losses, which may result in a decline in our stock price.

The worldwide energy industry is highly fragmented and we are competing with numerous companies looking for renewable energy technologies and capital related thereto. We are one of the smallest energy technology development companies and are an infinitely small participant in the oil and natural gas exploration business. The presence of competing technology development companies will impact our ability to raise additional capital in order to fund our technology programs if investors are of the view that investments in competitors are more attractive. We will also be competing with other technology companies for available resources, including, but not limited to, qualified personnel, properties suitable for exploration and development, and green energy technologies.

The current global economic and financial crisis could lead to an extended national or global economic recession. A slowdown in economic activity caused by a recession would likely reduce national and worldwide demand for oil and natural gas and result in lower commodity prices for long periods of time. Prices for oil and natural gas have decreased significantly from highs in 2008. In the last eighteen months, oil prices have decreased by up to one half their highest prices and natural gas prices have decreased by more than two thirds during this time period. Costs of exploration, development and production have not yet adjusted to current economic conditions or in proportion to the reduced product prices. Prolonged, substantial decreases in oil and natural gas prices would likely have a material adverse effect on Regent's business, financial condition and results of operations, could further limit the Company's access to credit and could hinder its ability to satisfy its capital requirements.

Capital and credit markets have experienced unprecedented volatility and disruption during the last half of 2008 and continued to be unpredictable through 2009 and into 2010. Given the current levels of market volatility and disruption, the availability of funds from those markets has diminished very substantially. Further, arising from concerns about the stability of financial markets generally and the solvency of borrowers specifically, the cost of accessing the credit markets has increased as many lenders have raised interest rates, enacted tighter lending standards or have altogether ceased to provide funding to borrowers. Accordingly, we are evaluating numerous and various alternatives, such as joint ventures with third parties, or sales of interest in one or more of its properties. Such transactions if undertaken, could result in a reduction in the Company's operating interests or require the

7

Company to relinquish the right to operate the property. There can be no assurance that any such transactions can be completed or that such transactions will satisfy the Company's operating capital requirements.

Our Company has no commitments to obtain any additional financing and there can be no assurance that additional financing will be available, when required, on favorable terms to us. The inability to obtain additional financing could have a material adverse effect on us, including requiring us to curtail our oil and natural gas acquisition and development plans of our properties and technology development of our emerging energy technologies. Any additional financing may involve substantial dilution to the interests of our shareholders at that time.

Our directors and executive officers collectively own most of our outstanding voting stock. Accordingly, these stockholders, as a group, will be able to control the outcome of stockholder votes, including votes concerning the election of directors, the adoption or amendment of provisions in our Articles of Incorporation and our Bylaws, and the approval of mergers and other significant corporate transactions. These factors may also have the effect of delaying or preventing a change in our management or our voting control. Our Articles of Incorporation do not provide for cumulative voting.

The liquidity of our common stock may be adversely affected, and purchasers of our common stock may have difficulty selling our common stock, if our common stock does not trade in a suitable trading market. There is presently a limited public market for our common stock, and there is no assurance that a market for our securities will develop. It is likely that any market for our common stock will be highly volatile and that trading in any such market will be limited. The trading price of our common stock could be subject to wide fluctuations in response to quarter-to-quarter variations in our operating results, notices of our drilling results and other events or factors.

We have not paid any cash dividends on our common stock since our inception and we do not anticipate paying cash dividends in the foreseeable future. We intend to retain our earnings, if any, to provide funds for reinvestment in our acquisition and exploration activities. Therefore, we do not anticipate declaring or paying dividends in the foreseeable future. Further, payment of dividends, if any, in the future is within the discretion of the board of directors and will depend on our earnings, if any, our capital requirements and financial condition and other relevant factors.

We will own or lease properties that for many years have produced oil and natural gas. It is not uncommon for such properties to be contaminated with hydrocarbons. Although we or previous owners of these interests may have used operating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under the properties or on or under other locations where such wastes have been taken for disposal. These properties may be subject to federal or state requirements that could require us to remove any the wastes or to remediate the resulting contamination. In addition to properties that we operate, we have interests in many properties which are operated by third parties over whom we have limited control. Notwithstanding our lack of control over properties operated by others, the failure of the previous owners or operators to comply with applicable environmental regulations may, in certain circumstances, adversely impact us.

Drilling activities are subject to many risks, including the risk that no commercially productive oil or gas reservoirs will be encountered. There can be no assurance that new wells drilled by us will be productive or that we will recover all or any portion of our investment. Drilling for oil and natural gas may involve unprofitable efforts, not only from dry wells, but also from wells that are productive but do not produce sufficient net revenues to return a profit after drilling, operating and other costs. The cost of drilling, completing and operating wells is often uncertain. Our drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, many of which are beyond our control, including economic conditions, mechanical problems, high pressure or irregularities in

8

formations, title problems, weather conditions, compliance with governmental requirements and shortages in or delays in the delivery of equipment and services. In today's environment, shortages make drilling rigs, labor and services difficult to obtain and could cause delays or inability to proceed with our drilling and development plans. Such equipment shortages and delays sometimes involve drilling rigs where inclement weather prohibits the movement of land rigs causing a high demand for rigs by a large number of companies during a relatively short period of time. Regent's future drilling activities may not be successful. Lack of drilling success could have a material adverse effect on our financial condition and results of operations.

Our operations are also subject to all the hazards and risks normally incident to the development, exploitation, production and transportation of, and the exploration for, oil and natural gas, including unusual or unexpected geologic formations, pressures, down hole fires, mechanical failures, blowouts, leaks, explosions, uncontrollable flows of oil, gas or well fluids and pollution and other environmental risks. These hazards could result in substantial losses to us due to injury and loss of life, severe damage to and destruction of property and equipment, pollution and other environmental damage and suspension of operations. We participate in insurance coverage maintained by the operator of its wells, although there can be no assurances that such coverage will be sufficient to prevent a material adverse effect to us in such events.

The vast majority of our oil and natural gas reserves are classified as proved reserves. Recovery of the Company's future proved undeveloped reserves will require significant capital expenditures as will the pursuit of the acquisition of producing oil and natural gas properties and leases. Regent's management estimates, but can make no guarantee, that our financing sources will be sufficient to fund our planned development activities or that development activities will be either successful or in accordance with our schedule. Additionally, any significant decrease in oil and natural gas prices or any significant increase in the cost of development could result in a significant reduction in the number of wells reworked and/or drilled. No assurance can be given that any wells will produce oil or gas in commercially profitable quantities.

The Obama administration has recently set forth budget proposals which if passed, would significantly curtail our ability to attract investors and raise capital. Proposed changes in the federal income tax laws which would eliminate or reduce the percentage depletion deduction and the deduction for intangible drilling and development costs for small independent producers, will greatly reduce the investment capital available to those in the industry as well as our Company. An extended time to expense seismic costs will also have an adverse effect on our ability to explore and find new reserves.

Our oil and natural gas business involves a variety of operating risks, including, but not limited to, unexpected formations or pressures, uncontrollable flows of oil, gas, brine or well fluids into the environment (including groundwater contamination), blowouts, fires, explosions, pollution and other risks, any of which could result in personal injuries, loss of life, damage to properties and substantial losses. Although we carry insurance at levels that we believe are reasonable, we are not fully insured against all risks. We do not carry business interruption insurance. Losses and liabilities arising from uninsured or under-insured events could have a material adverse effect on our financial condition and operations.

We plan to increase to some extent our development and, to a lesser extent, our exploration activities. Drilling of oil and natural gas reserves involve a high degree of risk that no commercial production will be found and/or that production will be insufficient to recover drilling and completion costs. The cost of drilling, completing and operating wells is often uncertain. Our drilling operations may be curtailed, delayed or canceled as a result of numerous factors, including title problems, weather conditions, compliance with governmental requirements and shortages or delays in the delivery of equipment. Furthermore, completion of a well does not assure a profit on the investment or a recovery of drilling, completion and operating costs.

WE ARE SUBJECT TO CERTAIN TITLE RISKS.

Our Company employees and contract land professionals have reviewed title records or other title review materials relating to substantially all of our producing properties. The title investigation performed by us prior to acquiring undeveloped properties is thorough, but less rigorous than that conducted prior to drilling, consistent with industry standards. We believe we have satisfactory title to all our producing properties in accordance with standards generally accepted in the oil and natural gas industry. Our properties are subject to customary royalty interests, liens incident to operating agreements, liens for current taxes and other burdens, which we believe do not materially interfere with the use of or affect the value of such properties.

Our revenues, profitability, and the book value of our oil and natural gas properties are substantially dependent upon prevailing prices of, and demand for, oil and natural gas and the costs of acquiring, finding, developing, and producing reserves. Our ability to obtain borrowing capacity, to repay future indebtedness, and to obtain additional capital on favorable terms is also primarily dependent upon oil and natural gas prices which historically have been subject to wide fluctuations in response to: (i) relatively minor changes in the supply of, and demand for, oil and natural gas; (ii) market uncertainty; and (iii) a variety of additional factors, all of which are beyond our control. These factors include domestic and foreign political conditions, the price and availability of domestic and imported oil and natural gas, the level of consumer and industrial demand, weather, domestic, and foreign government relations, the price and availability of alternative fuels and overall economic conditions. Also, the marketability of our production depends in part upon the availability, proximity and capacity of gathering systems, regulated pipelines and processing facilities.

We are responsible for payment of plugging and abandonment costs on our oil and natural gas properties pro rata to our working interest. Based on our experience, we anticipate that in most cases, the ultimate aggregate salvage value of lease and well equipment located on our properties should be equal to the costs of abandoning such properties. There can be no assurance, however, that we will be successful in avoiding additional expenses in connection with the abandonment of any of our properties. In addition, abandonment costs and their timing may change due to many factors, including actual production results, inflation rates and changes in environmental laws and regulations.

Our operations are affected from time to time in varying degrees by political developments and federal, state and local laws and regulations. In particular, oil and natural gas production related operations are or have been subject to price controls, taxes and other laws and regulations relating to the oil and natural gas industry. Failure to comply with such laws and regulations can result in substantial penalties. The regulatory burden on the oil and natural gas industry increases our cost of doing business and affects our profitability. Although we believe we will work in substantial compliance with all applicable laws and regulations, because such laws and regulations are frequently amended or reinterpreted, we are unable to predict the future cost or impact of complying with such laws and regulations.

Sales of natural gas by us are not regulated and are generally made at market prices. However, the Federal Energy Regulatory Commission ("FERC") regulates interstate natural gas transportation rates and service conditions, which will affect the marketing of natural gas produced by us, as well as the revenues received by us for sales of such production.

10

Since the mid-1980's, the FERC has issued a series of orders, culminating in Order Nos. 636, 636-A and 636-B ("Order 636"), that have significantly altered the marketing and transportation of natural gas. FERC Order 636 mandated a fundamental restructuring of interstate pipeline sales and transportation service, including the unbundling by the interstate pipelines of the sale, transportation, storage and other components of the city-gate sales services that such pipelines previously performed. One of the FERC's purposes in issuing orders was to increase competition. While any additional FERC action on these matters would affect us only indirectly, these policy statements and proposed rules and new changes are intended to further enhance competition in natural gas markets. We cannot predict what direction the FERC will take on these matters, nor can we predict whether the FERC's actions will achieve its stated goal of increasing competition in natural gas markets. However, we do not believe that we will be treated materially differently than other natural gas producers and marketers with which we will compete.

The price we receive from the sale of oil is affected by the cost of transporting such products to market. Effective January 1, 1995, the FERC implemented regulations establishing an indexing system for transportation rates for oil pipelines which would index such rates to inflation. These regulations could increase the cost of transporting oil by interstate pipelines or reduce wellhead prices for oil.

The State of Texas and many other states regulate oil and natural gas operations including permits for drilling, field operations, bonds and reports concerning operations and impose other requirements relating to the exploration for and production of oil and natural gas. Texas also has statutes or regulations addressing conservation matters, including provisions for the unitization or pooling of oil and natural gas properties, the establishment of maximum rates of production from wells and the regulation of spacing, and abandonment.

Estimates of oil and natural gas reserves are inherently imprecise. The process of estimating oil and natural gas reserves is complex. It requires interpretations of available technical data and many assumptions, including assumptions relating to economic factors. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves. To prepare our estimates, we must project production rates and the timing of development expenditures. We must also analyze available geological, geophysical, production and engineering data. The extent, quality and reliability of this data can vary. The process also requires economic assumptions about matters such as oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds for capital expenditures. The present value of future net cash flows from our proved reserves may not be necessarily the same as the current market value of the Company's estimated oil and natural gas reserves. We base the estimated discounted future net cash flows from our proved reserves on prices and costs in effect on the day of estimate which may change suddenly and significantly.

Our operations and properties will be subject to extensive and changing federal, state and local laws and regulations relating to environmental protection, including the generation, storage, handling and transportation of oil and natural gas and the discharge of materials into the environment, and relating to safety and health. The recent trend in environmental legislation and regulation generally is toward stricter standards, and this trend will likely continue. These laws and regulations may require the acquisition of a permit or other authorization before construction or drilling commences and for certain other activities; limit or prohibit construction, drilling and other activities on certain lands lying within wilderness and other protected areas; and impose substantial liabilities for pollution resulting from our operations. The permits required for our various operations are subject to revocation, modification and renewal by issuing authorities. Governmental authorities have the power to enforce compliance with their regulations, and violations are subject to fines, penalties or injunctions. In the opinion of management, we are in substantial compliance with current applicable environmental laws and regulations, and we have no material commitments for capital expenditures to comply with existing environmental requirements. Nevertheless, changes in existing environmental laws and regulations or in interpretations thereof could have a significant impact on us. The

11

impact of such changes, however, would not likely be any more burdensome to us than to any other similarly situated oil and natural gas company.

The federal Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), also known as the "Superfund" law, and similar state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons that are considered to have contributed to the release of a "hazardous substance" into the environment. These persons include the owner or operator of the disposal site or sites where the release occurred and companies that disposed or arranged for the disposal of the hazardous waste and substances found at the site. Persons who are or were responsible for releases of hazardous substances under CERCLA may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources. Furthermore, neighboring landowners and other third parties may file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment.

We will generate typical oil and natural gas field wastes, including hazardous wastes that are subject to the Federal Resources Conservation and Recovery Act and comparable state statutes. The United States Environmental Protection Agency and various state agencies have limited the approved methods of disposal for certain hazardous and non-hazardous wastes. Furthermore, some wastes generated by our oil and natural gas operations that are currently exempt from regulation may in the future be designated as "hazardous wastes", and therefore be subject to more rigorous and costly operating and disposal requirements.

Also, the Oil Pollution Act ("OPA") imposes a variety of requirements on responsible parties for onshore and offshore production facilities and vessels related to the prevention of oil spills and liability for damages resulting from such spills in waters of the United States. The "responsible party" includes the owner or operator of an onshore facility or vessel or the lessee or permittee of, or the holder of a right of use and easement for, the area where an onshore facility is located. OPA assigns liability to each responsible party for oil spill removal costs and a variety of public and private damages from oil spills. Few defenses exist to the liability for oil spills imposed by OPA. OPA also imposes financial responsibility requirements. Failure to comply with ongoing requirements or inadequate cooperation in a spill event may subject a responsible party to civil or criminal enforcement actions.

On July 28, 2011, the EPA proposed rules that would establish new air emission controls for oil and natural gas production and natural gas processing operations. Specifically, the EPA's proposed rule package includes New Source Performance Standards to address emissions of sulfur dioxide and volatile organic compounds ("VOCs") and a separate set of emission standards to address hazardous air pollutants frequently associated with oil and natural gas production and processing activities. The EPA's proposal would require the reduction of VOC emissions from oil and natural gas production facilities by mandating the use of "green completions" for hydraulic fracturing, which requires the operator to recover rather than vent the gas and natural gas liquids that come to the surface during completion of the fracturing process. The proposed rules also would establish specific requirements regarding emissions from compressors, dehydrators, storage tanks, and other production equipment. In addition, the rules would establish new leak detection requirements for natural gas processing plants. The EPA is currently considering public comments submitted on the proposed rules and has indicated that it expects to take final action on the proposed rules by April 3, 2012. If finalized, these rules could require a number of modifications to our operations including the installation of new equipment. Compliance with such rules could result in significant costs, including increased capital expenditures and operating costs, and could adversely affect our business.

The Company's operations depend on its ability to obtain financing for its working capital and capital expenditure requirements and for making future acquisitions. If the Company is not able to obtain suitable financing, its costs could increase and its revenues could decrease, or the Company could be precluded from continuing its operations at current or desired levels, or from making future acquisitions. Increases in interest rates can make it more difficult

12

and expensive to obtain the funds needed to operate the Company's businesses. The applicable interest rates on the revolving bank credit facilities that the Company has in place fluctuate based on changes in short-term interest rates. Increases in interest rates would increase the Company's interest expense and adversely affect the Company's results of operations and its ability to make acquisitions.

To manage the Company's future growth, the Company's management must continue to improve operational and financial systems. As the Company continues to grow, it will also need to recruit and retain additional qualified management personnel, and its ability to do so will depend upon a number of factors, including the Company's results of operations and prospects and the level of competition then prevailing in the market for qualified personnel. At the same time, the Company will likely be required to manage an increasing number of relationships with various customers and other parties. If the Company's management personnel, systems, procedures and controls are inadequate to support its operations, expansion could be slowed or halted and the opportunity to gain significant additional market share could be impaired or lost. Any inability on the part of the Company's management to manage the Company's growth effectively may adversely affect its results of operations.

Although the Company evaluates its internal controls over financial reporting and the Company's disclosure controls and procedures at the end of each quarter, any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of the controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on the Company's results of operations.

Water is an essential component of both the drilling and hydraulic fracturing processes. Historically, we have been able to purchase water from various sources for use in our operations. During 2011 and 2012, East and Central Texas experienced the lowest inflows of water in recent history. As a result of this severe drought, some local water districts may begin restricting the use of water subject to their jurisdiction for drilling and hydraulic fracturing in order to protect the local water supply. If we are unable to obtain water to use in our operations from local sources, we may be unable to economically produce oil and natural gas, which could have an adverse effect on our financial condition, results of operations and cash flows.

None.

Our properties consist primarily of oil and natural gas wells and our ownership in leasehold acreage, both developed and undeveloped. Our property acquisition efforts are and will be focused on pursuing opportunities that fit well within existing Company properties, in areas where we are establishing new operations or in areas where we believe that a base of existing production will produce an adequate foundation for economies of scale. Since the third quarter of 2010, we have been primarily committed to investing in developmental oil wells in the Mexia-Talco Fault Zone of the East Texas Basin. We continue to review prospects in the Midland Basin and the Gulf Coast Basin, both mature producing oil and natural gas horizons.

The following table sets forth our estimated proved reserves, as of December 31, 2012, based on the new SEC rules as defined in Rule 4.10(a) of Regulation S-X and Item 1200 of Regulation S-K:

13

In December 2008, the SEC released its finalized rule for "Modernization of Oil and Gas Reporting." The new rule requires disclosure of oil and natural gas proved reserves by significant geographic area, using the arithmatic 12-month average beginning-of-the-month price for the year, as opposed to using year-end prices as was practiced in all previous years. The rule also allows for the use of reliable technologies to estimate proved reserves, contingent on demonstrated reliability in conclusions about reserve volumes. Under the new rules, companies are required to report on the independence and qualifications of their reserve preparers or auditors, and file reports when a third-party is relied upon to prepare reserve estimates or conduct a reserve audit.

Processes and Controls. There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves and estimates of reserve quantities and values must be viewed as being subject to significant change as more data about the properties become available. The independent engineering firm RCM Engineering, Inc. of Dallas, Texas ("RCM"), has estimated our oil and natural gas reserves and the present value of future net revenues therefrom as of December 31, 2012. Those estimates were determined based on prices and costs as of or for the twelve month period ended December 31, 2012. RCM meets the requirements with regard to qualifications, independence, objectivity and confidentiality set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. RCM does not own an interest in any of our properties and is not employed by us on a contingent basis. We provide historical information to RCM for our properties such as ownership interest; oil and natural gas production; well test data; commodity prices; and operating and development costs.

RCM's estimates of our reserves conform to the guidelines of the SEC and the estimated recoverable proved reserves have been determined without regard to any economic impact that may result from our financial derivative activities. These calculations were prepared using standard geological and engineering methods generally accepted by the petroleum industry. The reserve information shown is estimated. The certainty of any reserve estimate is a function of the quality of available geological, geophysical, engineering and economic data, and the precision of the

14

engineering and geological interpretation and judgment. The estimates of reserves, future cash flows and present value are based on various assumptions, and are inherently imprecise. Although we believe these estimates are reasonable, actual future production, cash flows, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves may vary substantially from these estimates.

The Company is not aware of any major discovery or other favorable or adverse event that is believed to have caused a significant change in the estimated proved reserves since December 31, 2012. Please read "Item 1A. Risk Factors -- Our estimated reserves are based on many assumptions that may turn out to be inaccurate. Any significant inaccuracies in these reserve estimates or underlying assumptions may materially affect the quantities and present value of our reserves." You should also read the notes following consolidated financial statements for the year ended December 31, 2012 in conjunction with the reserve estimates. Since January 1, 2010, we have not filed an estimate of our net proved oil and natural gas reserves with any federal authority or agency other than the SEC.

Undeveloped acreage includes leased acres on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas, regardless of whether or not such acreage contains proved reserves. A gross acre is an acre in which an interest is owned. A net acre is deemed to exist when the sum of fractional ownership interests in gross acres equals one. The table below sets forth our undeveloped and developed gross and net leasehold acreage as of December 31, 2012.

Our principal office is located at 5646 Milton, Suite 722, Dallas, Texas 75206.

We have no litigation and no known pending litigation.

Not applicable.

Regent's Common Stock is listed on the Over-the-Counter Bulletin Board under the symbol "REGT." For the period ended December 31, 2012, security dealers did not report high and low bid quotations.

There are currently 20,441,439 shares of common stock that are considered restricted securities under Rule 144 of the Securities Act of 1933 (the "Act"). Most of the restricted shares are held by affiliates, as that term is defined in Rule 144(a)(1). In general, under Rule 144 as amended, a person who has beneficially owned and held restricted

15

securities for at least a year, including affiliates, may sell publicly without registration under the Act, within any three-month period, assuming compliance with other provisions of the Act. In general, under Rule 144, as currently in effect, a person who has beneficially owned shares of a company's common stock for at least six months is entitled to sell within any three month period a number of shares that does not exceed the greater of:

General and Business Overview

Regent Technologies, Inc. is a technology-focused energy company that utilizes emerging proprietary technologies for our involvement in the energy industry. We have access to proprietary technologies which we believe provide us an advantage in the industry. Our business strategy is to exploit these advantages and generate long-term value for our shareholders and partners. Our Vision is to employ new technologies to maximize the production of petroleum resources in an efficient and environmentally safe manner while developing new technologies for the increased use of renewable energy. Our Mission is to accomplish our business strategy while maintaining the highest standards of integrity and professionalism wherever we operate and promoting responsible energy now and in the future.

Strategy. Our long term oil and natural gas development strategy is to increase profit margins and concentrate on obtaining producing and developmental properties with low cost operations and with the potential for long-lived production. We will also focus on the acquisition of minerals and royalties in areas with exploration and development potential. We intend to grow reserves and production economically, primarily by: (1) selectively acquiring prospects where levels of production can be raised quickly and sustained for the highest return on investment; (2) participating in and or actively conducting drilling operations in order to further exploit the existing properties; and (3) pursuing strategic acquisitions that can be improved with our production enhancement technologies.

Exploration activities will normally be conducted with the Company acquiring undeveloped oil and natural gas leases under prospects, and carrying out exploratory drilling on the prospective leasehold with the Company retaining a majority interest in the prospect. Interests in the property will sometimes be sold to key employees and associated companies at cost. Also, interests may be sold to third parties with the Company retaining an overriding royalty interest, carried working interest, or a reversionary interest.

Regent intends to rely on joint ventures with qualified operating oil and natural gas companies to operate its projects through the exploratory and production phases. This will reduce general and administrative costs necessary to conduct operations. As of the date of this filing, Regent is not operating any of the oil and natural gas wells in which it owns an interest but instead relies on third party companies to operate its oil and natural gas activities at this time. The cost of future oil and natural gas projects would be funded through borrowings and, if appropriate, sales of common or preferred stock of the Company or our subsidiary or sales of our investment in MacuCLEAR Preferred Stock.

Production. Pursuant to the Regent NRCo oil and natural gas property transaction agreement (PTA) during the third and fourth quarters of 2010, we acquired 3 leases which cover 66 gross acres in the Hill County, Texas. We also acquired a 50% net profits interest in a one well lease. We currently derive revenue from 2 productive wells with one well producing from the Woodbine formation and one well producing from the Austin Chalk formation. The 2 wells average combined production of 3-5 barrels per day. We have utilized 2 proprietary chemicals to treat formation damage and are reviewing a proposal to further stimulate the producing zones with the expectation that production may be increased 30-50%. The primary objective of owning and operating these wells is to gain experience with technologies that can significantly improve production in wells that have been abandoned or have remained dormant for a lengthy period of time.

Salt Water Operations. During 2012, we executed our right under the PTA to purchase the salt water injection equipment including related contract rights and permits plus additional production equipment. We produce a significant amount of water which is very costly to remove in trucks for proper disposal in approved facilities. The injection well is necessary to reduce the significant operating burden and costs of water disposal. Our system consists of a well permitted through the Railroad Commission of Texas, high-pressure injection pump and flow line with storage facilities. During the third and fourth quarters, significant downtime resulted due to high pressures from formation blockage following a procedure to remove wellbore scale. Currently, the injection well is being re-permitted to increase capacity by adding another formation horizon for injection.

Financing and Liquidity

Regent has funded operations through short-term borrowings and equity investment sales in order to meet obligations. Our future operations are dependent upon external funding and our ability to increase revenues and reduce expenses. There is no assurance that sufficient funding will be available from additional related party borrowings and private placements to meet our business objectives including anticipated cash needs for working capital.

Crude oil and natural gas prices have fluctuated significantly in recent years. The effect of declining prices on the oil business can be significant. Lower product prices will reduce our cash flow from operations and diminish the present value of our oil and natural gas reserves. Lower product prices also offer less incentive to assume the development risks that are inherent in our business. The volatility of the energy markets makes it extremely difficult to predict future oil and natural gas price movements with any certainty. The average oil price received in 2011 for the production under our net profits interest agreement has ranged from a high in April of $100.90 to a low in August of $79.97. The average oil price received in 2012 has ranged from a low of $74.50 in June to a high of $98.73 in April.

During the first and second quarters of 2012, the Company generated new cash of $20,610 and $83,094, respectively, from the sale of shares of its direct preferred stock holdings in MacuCLEAR, Inc. The bulk of these monies were used to re-enter and re-equip one of the wells acquired in 2010 and to acquire the salt water disposal well and refurbish injection pumping equipment. As of December 31, 2012, the Company had total assets of $625,287 and total liabilities of $116,021, of which $10,400 is the balance of the promissory note for the 2010 net profits interest acquisition. Accrued liabilities reflect an increase for the period ended December 31, 2012 from December 31, 2011 by $45,215 due to the acquisition of the salt water operations and additional oil and natural gas production equipment. We believe that cash flow from operations and funds available from financing will be sufficient to provide needed liquidity through this fiscal year.

Management bases its critical assumptions on historical experience, third-party data and various other estimates that it believes to be reasonable under the circumstances. Actual amounts could differ from those estimates. The significant accounting policies of the Company are described in the notes to the audited financial statements included herein. See Note 2 - "Summary of Significant Accounting Policies" to our consolidated financial statements for additional information.

The Company follows the full-cost method of accounting under which all costs associated with property acquisition, exploration and development activities are capitalized. We capitalize internal costs that can be directly identified with our acquisition, exploration and development activities and do not include any costs related to production, general corporate overhead or similar activities. Capitalized costs are amortized on a composite unit-of-production method based on proved oil and natural gas reserves. Estimates of our proved reserves as of each year-end are prepared by a third party engineering firm. In addition, upon significant changes, a third party engineering firm reviews and updates our reserves on a quarterly basis. Proceeds from the sale of properties are accounted for as reductions of capitalized costs unless such sales involve a significant change in the relationship between costs and the value of proved reserves or the underlying value of unproved properties, in which case a gain or loss is recognized.

Estimates of oil and natural gas reserves, by necessity, are projections based on geologic and engineering data, and there are uncertainties inherent in the interpretation of such data as well as the projection of future rates of production and the timing of development expenditures. Reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that are difficult to measure. The accuracy of any reserve estimate

18

is a function of the quality of available data, engineering and geological interpretation and judgment. Estimates of economically recoverable oil and natural gas reserves and future net cash flows necessarily depend upon a number of variable factors and assumptions, such as historical production from the area compared with production from other producing areas, the assumed effects of regulations by governmental agencies and assumptions governing future oil and natural gas prices, future operating costs, severance taxes, development costs and workover costs, all of which may in fact vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities of oil and natural gas attributable to any particular group of properties, classifications of such reserves based on risk of recovery, and estimates of the future net cash flows expected therefrom may vary substantially. Any significant variance in the assumptions could materially affect the estimated quantity and value of the reserves, which could affect the carrying value of oil and natural gas properties and/or the rate of depletion of the oil and natural gas properties. Actual production, revenues and expenditures with respect to our reserves will likely vary from estimates and such variances may be material.

While the estimates of our proved reserves at December 31, 2012 included in this report have been prepared based on what we and our independent reserve engineers believe to be reasonable interpretations of the new SEC rules, those estimates could differ materially from our actual results.

Regent has funded operations through short-term borrowings and equity investment sales in order to meet obligations. Our future operations are dependent upon external funding and our ability to increase revenues and reduce expenses. There is no assurance that sufficient funding will be available from additional related party borrowings and private placements to meet our business objectives including anticipated cash needs for working capital.

The Company had lower revenues for the period ended December 31, 2012 as compared to 2011 due to production downtime from power shortages and parts delays related to disposal operation repairs and maintenance. General and administrative expenses were up $11,120 for the period ended December 31, 2012 compared to the same period in 2011 due to third party consulting and increased travel, both related to prospect evaluation costs. Also, accounting support expense increased in the second and third quarters due to costs for the implementation of expanded XBRL reporting regulations under new SEC guidelines. Interest expense was $2,072 for 2012 compared to interest expense of $4,603 for 2011 and the decrease was due to lower interest bearing debt in 2012.

Oil and natural gas operating expenses added $1,594 for 2012 due to the new expenses related to the salt water disposal operations and the one producing well. The depreciation, depletion and amortization expense was comparable for both periods.

For the period ended December 31, 2011, the Company had a net loss of $34,107 compared to net income of $188,427 for the same period ended 2010. In addition, the Company realized operating revenue of $25,689 for 2011 from the net profits production interest compared to none in 2010. We also received an extraordinary consulting fee of $2,000 in 2010. The net income for fiscal 2010 was primarily the result of unrealized gains of $195,221 due to the fair value measurement of the MacuCLEAR Preferred Stock acquisition and the gain of $24,750 from investment sales. The loss was greater in 2011 due to higher administrative and interest expense and no gains from investment sales.

General and administrative expenses were $54,091 for the period ended December 31, 2011 compared to $30,300 for the period ended December 31, 2010. The increase was the result of higher accounting and audit expense, plus new expenses of $11,000 for director liability insurance. Interest expense was $4,603 for 2011 compared to net interest income of $756 for 2010. The increase in interest expense was due to new short term borrowings and the note payable related to the 2010 net profits interest acquisition. The depreciation, depletion and amortization expense for the period was $1,102 compared to $268 for the same period in 2010. The increase was due to $754 of depletion expense for 2011 compared to none for 2010.

LIQUIDITY AND CAPITAL RESOURCES

The Company finances its operations from internally generated funds from stock sales, proceeds from sales of its investments and from borrowings under its various agreements. The Company had total assets of $625,287 and total liabilities of $116,021 as of December 31, 2012 compared to total assets of $633,072 and total liabilities of $66,983 as of December 31, 2011. The decrease in assets was due primarily to net investment sales after higher accounting and insurance expenses and the new debt from the increase of accrued liabilities for the asset acquisitions. The Company does not have any delivery commitments to provide a fixed and determinable quantity of its oil and natural gas under any existing agreement.

Net cash flows provided from operating activities was $9,171, for the fiscal period ending December 31, 2012, compared to net cash flows used of $25,576 for the same period in 2011, primarily due to the increase in accrued expenses and in accounting and insurance expense. Revenues from the Company's oil and gas activities was $14,902 in 2012 compared to $25,689 in 2011 which decreased primarily due to salt water disposal system downtime.

Net cash flows from investing activities was $22,899 in 2012 compared to $45,386 in 2011 due to the sale of a portion of the Company's investment in MacuCLEAR stock for $102,114 in 2012 and $78,000 in 2011. In addition, the Company incurred capital expenditures of $79,215 in 2012 compared to $32,614 in 2011, all for oil and natural gas activities.

Net cash flows used by financing activities was $8,002 for 2012 and was $35,300 for 2011. Cash used in 2012 was primarily the total of $38,950 for long-term note payable reduction offset by short term borrowings of $30,948 for primarily due to the referenced increase in general and administrative expenses. Cash used in 2011 included the payment of $37,400 for debt reduction related to the oil and natural gas property acquisitions in 2010.

The Company is not performing any product research and development at this time and it is not expected to incur significant changes in the number of employees.

Our capital expenditures budget is focused on acquisitions which we intend to fund through the issuance of common and preferred stock.

The Company acquired certain oil and natural gas interests through the CEO and has borrowings from NR Partners. Also, the Company has sold a portion of its investment in securities of MacuCLEAR to the CEO and his spouse. See Note 11 - "Related Party Transactions" to our consolidated financial statements for additional information.

Neither the Company nor the Subsidiary have incurred contractual payment obligations. The Company is not expected to purchase equipment or incur significant changes in the number of employees in 2013.

As of the date of this report, we do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors. The term "off-balance sheet arrangement" generally means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with us is a party, under which we have: (i) any obligation arising under a guarantee contract, derivative instrument or variable interest; or (ii) a retained or contingent interest in assets transferred to such entity or similar arrangement that serves as credit, liquidity or market risk support for such assets.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Regent Technologies, Inc. and Subsidiary
Dallas, Texas

We have audited the accompanying consolidated balance sheets of Regent Technologies, Inc. and Subsidiary, (the Company) (a development stage company) as of December 31, 2012 and 2011, and the related consolidated statements of operations, stockholders' equity (deficit), and cash flows for the years ended December 31, 2012 and 2011, and for the period January 1, 1999 through December 31, 2012. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Regent Technologies, Inc. and Subsidiary at December 31, 2012 and 2011, and the results of their operations and cash flows for the years ended December 31, 2012 and 2011, and for the period January 1, 1999 through December 31, 2012 in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the consolidated financial statements, the Company has no significant business operations and has a working capital deficiency, both of which raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
