Electronic Offer, Sale and Distribution of Securities

A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters or selling group members. Other than the prospectus in electronic format, the information on these websites is not part of, nor incorporated by reference into, this prospectus or the registration statement of which this prospectus forms a part, has not been approved or endorsed by us, and should not be relied upon by investors.

Price Stabilization, Short Positions and Penalty Bids

In connection with this offering, the underwriters may engage in stabilizing transactions, overallotment transactions, syndicate covering transactions and penalty bids in connection with our common stock.

Stabilizing transactions permit bids to purchase shares of common stock so long as the stabilizing bids do not exceed a specified maximum.

Overallotment transactions involve sales by the underwriters of shares of common stock in excess of the number of shares the underwriter is obligated to purchase. This creates a syndicate short position which may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriter is not greater than the number of shares that it may purchase in the option to purchase additional shares. TheIn a naked short position, the number of shares involved is greater than the number of shares in the second column reflects these limitations.option to purchase additional shares. The Selling Stockholderunderwriter may sell all, some close out any short position by exercising its option to purchase additional shares and/or none of itspurchasing shares in the open market.

Syndicate covering transactions involve purchases of common stock in the open market after the distribution has been completed in order to cover syndicate short positions. Such a naked short position would be closed out by buying securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock in the open market may be higher than it would otherwise be in the absence of these transactions. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected on Nasdaq, in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time.

In connection with this offering. See “Planoffering, the underwriters also may engage in passive market making transactions in our common stock in accordance with Regulation M during a period before the commencement of Distribution.”

The holders of our common stock are entitled to one vote for each share held on all matters submitted to a stockholder vote and mayof the stockholders. The holders of our common stock do not cumulate their votes.have any cumulative voting rights. Holders of our common stock are entitled to share in allreceive ratably any dividends thatdeclared by our Board in its discretion, declares fromout of funds legally available funds. for that purpose, subject to any preferential dividend rights of any outstanding preferred stock. Our common stock has no preemptive rights, conversion rights or other subscription rights or redemption or sinking fund provisions.

In the event of our liquidation, dissolution or winding up, each outstanding share entitles its holder to participate pro rata in all assets that remain after payment of liabilities and after providing for each class of stock, if any, having preference over the common stock.

Our Board is authorized by our Certificate of Incorporationcharter to establish classes or series of preferred stock and fix the designation, powers, preferences and rights of the shares of each such class or series and the qualifications, limitations or restrictions thereof without any further vote or action by our stockholders. Any shares of preferred stock so issued could have priority over our common stock with respect to dividend or liquidation rights. Any future issuance of preferred stock may have the effect of delaying, deferring or preventing a change in our control without further action by our stockholders and may adversely affect the voting and other rights of the holders of our common stock.

The issuance of shares of preferred stock, or the issuance of rights to purchase such shares, could be used to discourage an unsolicited acquisition proposal. For instance, the issuance of a series of preferred stock might impede a business combination by including class voting rights that would enable a holder to block such a transaction. In addition, under certain circumstances, the issuance of preferred stock could adversely affect the voting power of holders of our common stock. Although our Board is required to make any determination to issue preferred stock based on its judgment as to the best interests of our stockholders, our Board could act in a manner that would discourage an acquisition attempt or other transaction that some, or a majority, of our stockholders might believe to be in their best interests or in which such stockholders might receive a premium for their stock over the then market price of such stock.

29

Anti-Takeover Effects of Certain Provisions of Delaware Law and Our Certificate of Incorporation and Bylaws

Our charter and bylaws contain a number of provisions that could make our acquisition by means of a tender or exchange offer, a proxy contest or otherwise more difficult. These provisions are summarized below.

Board Composition; Removal of Directors and Filling Board Vacancies

Our charter provides that stockholders may remove directors only for cause and only by the affirmative vote of the holders of at least a majority of the shares entitled to vote at an election of directors.  

Our bylaws authorize only our Board fill vacant directorships, including newly created seats. In addition, the number of directors constituting our Board may only be set by a resolution adopted by a majority vote of our entire Board. These provisions would prevent a stockholder from increasing the size of our Board and then gaining control of our Board by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our Board but promotes continuity of management.

Staggered Board

Our Board is divided into three classes, with one class of directors elected at each year’s annual stockholders meeting. Staggered terms tend to protect against sudden changes in management and may have the effect of delaying, deferring or preventing a change in our control without further action by our stockholders.

Advance Notice Requirements

Our bylaws provide advance notice procedures for stockholders seeking to bring matters before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders if the proper procedures are not followed. We expect that these provisions might also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our Company.

Special Meetings

Our bylaws provide that special meetings of stockholders may only be called at the request of a majority of the Board, and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders.

Undesignated Preferred Stock

Our charter provides for [●] authorized shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our Board to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our Board were to determine that a takeover proposal is not in the best interests of our stockholders, our Board could cause shares of convertible preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our charter grants our Board broad power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

30

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

Section 203 defines a business combination to include:

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Transfer Agent and Registrar

The transfer agent and registrar of our common stock is Computershare Investor Services.

Common Warrants

The following summary of certain terms and provisions of the Common Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Common Warrants, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Common Warrant for a complete description of the terms and conditions of the warrants. The Common Warrants will be issued in book-entry form and will initially be represented only by one or more global warrants deposited with the warrant agent, as custodian on behalf of The Depository Trust Company, or DTC, and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC pursuant to a warrant agency agreement between us and Computershare, Inc. together with its wholly-owned subsidiary, Computershare Trust Company, N.A., as warrant agent.

Duration and Exercise Price

The warrants are exercisable from and after the date of their issuance and expire on the five year anniversary of such date, at an exercise price per share of common stock equal to $_____. The warrants will be governed by the terms of a global warrant held in book-entry form. The holder of a warrant will not be deemed a holder of our underlying common stock until the warrant is exercised. No fractional shares of common stock will be issued in connection with the exercise of a warrant. Instead, for any such fractional share that would have otherwise been issued upon exercise of warrants, we will round such fraction up to the next whole share.

31

Exercisability

The warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). [Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.9% of the shares of common stock outstanding.]

Cashless Exercise 

If, at the time a holder exercises its warrants, a registration statement registering the issuance of the shares of common stock underlying the warrants under the Securities Act is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the warrants.

Transferability

Subject to applicable laws, a warrant may be transferred at the option of the holder upon surrender of the warrant to us together with the appropriate instruments of transfer.

Fractional Shares

No fractional shares of common stock will be issued upon the exercise of the warrants. Rather, the number of shares of common stock to be issued will be rounded to the nearest whole number.

Trading Market

There is currently no established public trading market for the warrants, and there is no assurance that a market will develop. We are in the process of applying to have the warrants listed on Nasdaq under the symbol “ASTIW.” We will not consummate this offering unless our shares of common stock and warrants are approved for listing on Nasdaq.

Right as a Stockholder

Except as otherwise provided in the warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the warrants do not have the rights or privileges of holders of our common stock with respect to the shares of common stock underlying the warrants, including any voting rights, until they exercise their warrants. The warrants will provide that holders have the right to participate in distributions or dividends paid on our common stock.

Fundamental Transaction

In the event of a fundamental transaction, as described in the warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the warrants will be entitled to receive upon exercise of the warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the warrants immediately prior to such fundamental transaction. Additionally, as more fully described in the warrants, in the event of a fundamental transaction (as defined in the warrants), the holders of the warrants will be entitled to receive consideration in an amount in cash equal to the Black Scholes value of the warrants determined according to a formula set forth in the warrants, provided, however, that, if the fundamental transaction is not within our control, including not approved by our Board, then the holder shall only be entitled to receive the same type or form of consideration (and in the same proportion), at the Black Scholes value of the unexercised portion of the warrant, that is being offered and paid to the holders of our common stock in connection with the fundamental transaction.

32

Warrant Agent

The warrants will be issued pursuant to the terms of a warrant agency agreement between us and Computershare, Inc. together with its wholly-owned subsidiary, Computershare Trust Company, N.A., as warrant agent. The warrant agent may resign upon 30 days’ written notice to us and our transfer agent , if applicable. We have the right to remove the warrant agent upon 30 days’ prior written notice to the warrant agent, our transfer agent and the holders of any warrant certificates. If the warrant agent resigns or is removed, we will appoint a successor warrant agent. If we do not do so within 30 days, then any holder of a warrant certificate may petition a court of competent jurisdiction to appoint a successor warrant agent and we will be deemed to be the warrant agent pending such appointment. In the warrant agency agreement, we have agreed to indemnify the warrant agent against certain liabilities.]

DESCRIPTION OF BUSINESS

Business Overview

We target high-value specialty solar markets. These include aerospace, defense, emergency management and consumer/OEM applications. This strategy enables us to fully leverage the unique advantages of our technology, including flexibility, durability and attractive power to weight and power to area performance. It further enables us to offer unique, differentiated solutions in large markets with less competition, and more attractive pricing.

Specifically, we focus on commercializing our proprietary solar technology in three highest-value PV verticals:

I. Aerospace: Space, Near-space and Fixed Wing UAV

II. Public Sector: Defense and Emergency Management

III. Commercial Off-grid and Portable Power

We believe the value proposition of Ascent’s proprietary solar technology not only aligns with the needs of customers in these verticals, but also overcomes many of the obstacles other solar technologies face in these unique markets. Ascent has the capability to design and develop finished products for end users in these areas as well as collaborate with strategic partners to design and develop custom integrated solutions for products like airships and fixed-wing UAVs. Ascent sees significant overlap in the needs of end users across some of these verticals and believes it can achieve economies of scale in sourcing, development, and production in commercializing products for these customers.

The integration of Ascent's solar modules into space, near space, and aeronautic vehicles with ultra-lightweight and flexible solar modules is an important market opportunity for the Company. Customers in this market have historically required a high level of durability, high voltage and conversion efficiency from solar module suppliers, and we believe our products are well suited to compete in this premium market.

Product History

In March 2008, we demonstrated initial operating capacity of our first production line by beginning production trials as an end-to-end integrated process. Initial operating capacity production trials resulted in average thin film device efficiencies of 9.5% and small area monolithically integrated module efficiencies of over 7.0%. During 2008, optimization trials resulted in thin film device efficiencies in the 9.5% to 11.5% range and corresponding module efficiencies in the 7.0% to 9.0% range. The test modules measured approximately 15 centimeters wide by 30 centimeters long, which is significant in that it demonstrates true production capability where these modules are processed side-by-side. In contrast, devices tested under laboratory conditions are usually small area in nature measuring 1 centimeter by 1 centimeter or less. During the first quarter of 2009, we began limited production of monolithically integrated flexible CIGS modules in our initial production line. Our primary business model, at that time, was based upon mass production of solar modules of varying lengths, sizes and configurations. We provided sample modules to potential customers and development partners in various industries to explore integration of our products into new applications.

In July 2009, we obtained independent verification by the U.S. Department of Energy’s National Renewable Energy Laboratory (“NREL”) that our modules of approximately 15 centimeters wide by 30 centimeters long measured 10.4% in conversion efficiency. In October 2009, NREL further verified our achievement of a manufacturing milestone of 14.0% cell efficiency as well as a peak efficiency of 11.4% for CIGS modules. Later, in December 2010, we achieved 12.1% module efficiency on the same form factor. In October 2010, we completed internal qualification testing of a flexible packaging solution which successfully passed the rigorous standard of one thousand (1,000) hours of damp heat testing (85% relative humidity and 85° C temperature) guideline set forth by International Electrotechnical Commission (“IEC”) 61646 standards for performance and long-term reliability of thin film solar modules.

In February 2010, three of our product configurations were certified by an independent laboratory on a variety of U.S. Department of Defense (“DOD”) rugged standards known as MIL-STD-810G. In October 2010, we completed full external certification under IEC 61646 at an independent laboratory of a two-meter module. Achieving this certification is required for building integrated photovoltaic (“BIPV”) and building applied photovoltaic (“BAPV”) applications used in commercial, industrial and residential rooftop markets. Certification activities will continue, as required, as we introduce new products and make changes or improvements to our already certified products.

34

In 2010, we received an award from R&D Magazine and were recognized as one of the 100 Most Innovative Technologies, based on our process of monolithic integration on polyimide substrate. In 2011, Time Magazine selected us as one of the 50 Best Inventions of the year. In 2015 Ascent Solar won its second R&D 100 Award. The 2015 award was given for the development of the MilPak™ platform, a military-grade (MIL-STD-810G tested) and fully integrated solar power generation and storage unit incorporated with a Maximum Peak Power Tracking (MPPT) management system. The MilPak platform is one of the most rugged, yet lightweight, power generation and storage solutions available, both attributes enabled by the use of Ascent’s CIGS technology.

In January 2017, Ascent was awarded a contract to supply high-voltage SuperLight thin-film CIGS PV blankets. These 50W, fully laminated, flexible blankets were manufactured using a new process that was optimized for high performance in near-space conditions at elevated temperatures, and are custom designed for easy modular integration into series and parallel configurations to achieve the desired voltage and current required for such application.

In November 2017, Ascent introduced the next generation of our USB-based portable power systems with the XD™ series. The first product introduced was the XD-12 which, like previous products, is a folding, lightweight, easily stowable, PV system with USB power regulation. Unique to this generation of PV portable power is more PV power (12 Watts) and a 2.0 Amp smart USB output to enable the XD-12 to charge most smartphones, tablets, and USB-enabled devices as fast as a wall outlet. The enhanced smart USB circuit works with the device to be charged so that the device can determine the maximum power it is able to receive from the XD-12 and ensures the best possible charging performance directly from the sun.

Also in 2017, Ascent manufactured a new micro-module for a space customer, approximately 12.8mm x 50mm (0.5in x 2.0in) in size that is ideal for both laboratory-scale environmental testing, and for subsequent integration into flight experiments.

In February 2018, the Company introduced the second product in our XD series. Delivering up to 48 Watts of solar power, we believe the durable and compact Ascent XD-48 Solar Charger is the ideal solution for charging many portable electronics and off-grid power systems. The XD-48’s versatility allows it to charge both military and consumer electronics directly from the sun wherever needed. Like the XD-12, the XD-48 has a compact and portable design, and its rugged, weather-resistant construction withstands shocks, drops, damage and even minor punctures to power through the harshest conditions.

In March 2018, we collaborated with a European based customer for their lighter-than-air, helium-filled airship project, which was based on our newly developed ultra-light modules with substrate material that was half of the thickness of our standard modules. In 2019, we completed a repeat order from the same customer who had since established its airship development operation in the US. In 2020, we received a third and enlarged order from the same customer and completed the order in the second quarter of 2021. Most recently, in the 4^th quarter of 2021 we received a fourth order with a targeted ship date in the 2^nd quarter of 2022.

On September 15, 2021, the Company entered into a Long-Term Supply and Joint Development Agreement (“JDA”) with TubeSolar, a significant existing stakeholder in the Company. Under the terms of the JDA, the Company will produce, and TubeSolar will purchase, thin-film PV foils (“PV Foils”) for use in TubeSolar’s solar modules for agricultural photovoltaic (“APV”) applications that require solar foils for its production. Under the JDA, the Company will receive up (i) to $4 million of non-recurring engineering (“NRE”) fees, (ii) up to $13.5 million of payments upon achievement of certain agreed production and cost structure milestones, and (iii) product revenues from sales of PV Foils to TubeSolar. The JDA has no fixed term, and may only be terminated by either party for breach.

The Company and TubeSolar have also jointly established a subsidiary company in Germany, in which TubeSolar holds a minority stake of 30% (the “JV”). The purpose of the JV is to establish and operate a PV manufacturing facility in Germany that will produce and deliver PV Foils exclusively to TubeSolar. Until the JV facility is fully operational, PV Foils will be manufactured in the Company’s existing facility in Thornton, Colorado. The parties expect to jointly develop next generation tooling for use in manufacturing PV Foils at the JV facility. The Company purchased 17,500 shares of the JV for 1 Euro per share, on November 10, 2021. There has been no activity under the JV as of September 30, 2021.

We continue to design and manufacture PV integrated portable power applications for commercial and military users, including the US Marine Corps, US AF Special Operations Command, US Special Operations Command, US Army Special Operations Command, US Army Futures Command, and others. Due to the high durability enabled by the monolithic integration employed by our technology, the capability to customize modules into different form factors and the industry leading light weight and flexibility provided by our modules, we believe that the potential applications for our products are extensive, including anywhere that may need power generation such as in disaster recovery and emergency preparedness,

35

commercial and personal adventure expeditions to remote areas, humanitarian efforts in areas with poor power infrastructure, photography and filming involved in wildlife observation, to name a few.

Commercialization and Manufacturing Strategy

We manufacture our products by affixing a thin CIGS layer to a flexible, plastic substrate using a large format, roll-to-roll process that permits us to fabricate our flexible PV modules in an integrated sequential operation. We use proprietary monolithic integration techniques which enable us to form complete PV modules with little to no costly back-end assembly of inter-cell connections. Traditional PV manufacturers assemble PV modules by bonding or soldering discrete PV cells together. This manufacturing step typically increases manufacturing costs and, at times, proves detrimental to the overall yield and reliability of the finished product. By reducing or eliminating this added step, using our proprietary monolithic integration techniques, we believe we can achieve cost savings in, and increase the reliability of, our PV modules. All tooling necessary for us to meet our near-term production requirements is installed in our Thornton, Colorado plant.

We plan to continue the development of our current PV technology to increase module efficiency, improve our manufacturing tooling and process capabilities and reduce manufacturing costs. We also plan to continue to take advantage of research and development contracts to fund a portion of this development.

Advantages of CIGS on a Flexible Plastic Substrate

Thin film PV solutions differ based on the type of semiconductor material chosen to act as a sunlight absorbing layer, and also on the type of substrate on which the sunlight absorbing layer is affixed. To the best of our knowledge, we believe we are the only company in the world currently focused on commercial scale production of PV modules using CIGS on a flexible, plastic substrate with monolithic integration. We utilize CIGS as a semiconductor material because, at the laboratory level, it has a higher demonstrated cell conversion efficiency than amorphous silicon (“a-Si”) and cadmium telluride (“CdTe”). We also believe CIGS offers other compelling advantages over both a-Si and CdTe, including:

We believe our choice of substrate material further differentiates us from other thin film PV manufacturers. We believe the use of a flexible, lightweight, insulating substrate that is easier to install provides clear advantages for our target markets, especially where rigid substrates are unsuitable. We also believe our use of a flexible, plastic substrate provides us significant cost advantages because it enables us to employ monolithic integration techniques on larger components, which we believe are unavailable to manufacturers who use flexible, metal substrates. Accordingly, we are able to significantly reduce part count, thereby reducing the need for costly back end assembly of inter cell connections. As the only company, to our knowledge, focused on the commercial production of PV modules using CIGS on a flexible, plastic substrate with monolithic integration, we believe we have the opportunity to address the consumer electronics, defense, aerospace, transportation, off grid, portable power and other weight-sensitive markets with transformational high quality, value added product applications. It is these same unique features and our overall manufacturing process that enable us to produce extremely robust, light and flexible consumer products.

Competitive Strengths

We believe we possess a number of competitive strengths that provide us with an advantage over our competitors.

Markets and Marketing Strategy

We target high-value specialty solar markets. These include aerospace, defense, emergency management and consumer/OEM applications. This strategy enables us to fully leverage the unique advantages of our technology, including flexibility, durability and attractive power to weight and power to area performance. It further enables us to offer unique, differentiated solutions in large markets with less competition, and more attractive pricing.

Specifically, we focus on commercializing our proprietary solar technology in three highest-value PV verticals:

I. Aerospace: Space, Near-space and Fixed Wing UAV

II. Public Sector: Defense and Emergency Management

III. Commercial Off-grid and Portable Power

We believe the value proposition of Ascent’s proprietary solar technology not only aligns with the needs of customers in these verticals, but also overcomes many of the obstacles other solar technologies face in these unique markets. Ascent has the capability to design and develop finished products for end users in these areas as well as collaborate with strategic partners to design and develop custom integrated solutions for products like airships and fixed-wing UAVs. Ascent sees significant overlap in the needs of end users across some of these verticals and believes it can achieve economies of scale in sourcing, development, and production in commercializing products for these customers.

The integration of Ascent's solar modules into space, near space, and aeronautic vehicles with ultra-lightweight and flexible solar modules is an important market opportunity for the Company. Customers in this market have historically required a high level of durability, high voltage and conversion efficiency from solar module suppliers, and we believe our products are well suited to compete in this premium market. In May 2014, together with our partners, Silent Falcon UAS Technologies and Bye Aerospace, we announced the successful first flight of a production version of the Silent Falcon™ Unmanned Aircraft Systems, powered by Ascent’s ultra-lightweight, flexible PV modules. In July 2014, our ultra-lightweight, flexible PV modules were selected by Vanguard Space Technologies for their NASA Small Business Innovative Research program. The NASA program is intended to develop an economical, lightweight alternative to existing and emerging high-cost solar arrays for high-power space applications. We expect opportunities in this segment to develop rapidly due to customers' extensive development, testing and evaluation processes.

In March 2016, the Company announced a major breakthrough of our high-voltage superlight bare modules, achieving a power-to-weight ratio of 1,700 watts per kilogram at AM0 environment. The “best-in-class” specific power is crucial to the aerospace industry where every pound of weight reduction would translate to incremental cost savings or increased in payloads. In December 2016, Ascent was selected by the Japan Aerospace Exploration Agency (“JAXA”) as part of their next round of evaluations for providing solar technology for an upcoming mission to Jupiter, as well as to address additional missions. This decision followed an earlier round of investigation with promising results, during which the Company's flexible, monolithically integrated CIGS solar module was subjected to environmental extremes and continued to operate well. During the first phase of JAXA's evaluation, Ascent's PV was successfully tested below -146°C (-231°F) and up to +190°C (+374 °F), and to only 4% of the sunlight generally received in earth's orbit. In addition, JAXA has subjected Ascent's PV to radiation and mechanical testing.

In 2017 we continued to solidify our position in the space and near-space markets; these challenging requirements and environments allow for the full utilization of the unique nature and advantages of our lightweight, flexible monolithically integrated CIGS PV. Through continued work in the PV-powered drone field, Ascent made significant strides in providing PV power to high-altitude airships and next-generation space applications.

In January 2017, Ascent was awarded a contract to supply high-voltage SuperLight thin-film CIGS PV blankets. These 50W, fully laminated, flexible blankets were manufactured using a new process that was optimized for high performance in near-space conditions at elevated temperatures, and are custom designed for easy modular integration into series and parallel configurations to achieve the desired voltage and current required for such application.

In November 2017, Ascent fulfilled a third order from JAXA for custom PV products designed specifically for their upcoming solar sail deployment demonstration project.  This project was comprised of small area test cells and large, 19.5cm x 30cm monolithically integrated modules, all on a very thin, 25-micron (0.001 inch) plastic substrate which is half the thickness of Ascent’s production substrate for a standard product. In space, near-space, and drone applications, the PV substrate accounts for a significant portion of the product’s overall mass; the PV construction on the new 25-micron substrates represents a major breakthrough for these markets. JAXA placed this order after achieving the desired experimental results from the previous shipments and subsequent electrical, mechanical and environmental testing. The 19.5cm x 30cm module is a custom design to match the anticipated deployment mechanism and PV layout for the final Jovian spacecraft. We continue to receive testing orders from JAXA.

Also in 2017, Ascent fulfilled a new order, with another repeat space customer, to manufacture a new micro-module, approximately 12.8mm x 50mm (0.5in x 2.0in) in size that is ideal for both laboratory-scale environmental testing, and for subsequent integration into flight experiments.

In 2015 Ascent Solar won its second R&D 100 Award, the 2015 award was given for the development of the MilPak platform, a military-grade solar power generation and storage unit. The MilPak platform is one of the most rugged, yet lightweight, power generation and storage solutions available, both attributes enabled by the use of Ascent’s CIGS technology.

The military market has a unique set of requirements we believe are well suited to our products. When integrated with fabric to form re-deployable arrays, our highly efficient, rugged, lightweight modules may allow soldiers to minimize battery loads, reduce the use of conventional fuels, and increase safety through the streamlining of fuel transport operations, providing the front-line units with maximum resilience and helping to increase operational efficiency. We are also working to expand our foldable line of outdoor solar chargers, such as the XD-12 and the XD-48, which are well suited for the individual soldier or for the bigger power needs of a platoon with the ability of several chargers to be strung together. Our modules can also provide a reliable source of renewable power in remote areas, regardless of local infrastructure. We will continue to seek to

38

reach the military market through partnerships with top systems providers, by providing Government Service Administration Letters of Supply, and through direct sales and other blanket purchase agreements with the government.

Transportation integrated PV, or integration of our flexible solar modules with vehicles such as commercial trucks, buses, trains and passenger cars, is another market segment that we believe represents a significant opportunity. Due to their flexible form and durable, lightweight properties, our modules can be fitted to the exterior of various vehicles to provide supplemental power without significantly affecting the aerodynamics, weight or aesthetics of the vehicle. We are currently working with multiple integrators and OEMs to develop effective value-added solutions for this market.

During the third quarter of 2017, Ascent Solar demonstrated its breadth of capabilities at the US Special Operations Command (“SOCOM”) exclusive Technical Experimentation (“TE”) 17-3 Event in Washington, DC. SOCOM is tasked, by the Department of Defense (“DoD”), with providing Special Operations Forces (“SOF”) with the latest war fighting technology available; in support of this effort, SOCOM sponsors an annual TE event.   In July of 2017, SOCOM requested the participation of companies who have proficiency in the areas of Satellite Communication (“SATCOM”) and Unattended Ground Sensors (“UGS”) for a TE event.   Over 30 companies were selected to participate, and Ascent Solar was one of only 2 companies selected to participate who didn’t actually make SATCOM or UGS products.  Ascent Solar was selected on the basis and recognition that one of the primary issues facing the DoD today is the ability to power all of their war fighting technology.   Ascent’s diverse line-up of rugged and lightweight portable solar products offers the potential for the DoD to generate unattended ongoing power, which could save lives and increase the efficiency of the war fighting effort.  Ascent was honored to be chosen to participate, and the assessed score we received is indicative of a capability that has “high potential for SOF use with few limitations”. 

During the third quarter of 2018, Ascent Solar was once again selected to demonstrate its breadth of capabilities at the SOCOM exclusive TE 18-3 Event in Washington, DC. In July of 2018, SOCOM requested the participation of companies who have proficiency in the areas of Intelligence, Surveillance and Reconnaissance (ISR), Small Unmanned Aerial Systems (SUAS) and Mobility for the TE event.  Over 50 companies were selected to participate, and Ascent Solar was one of only 2 companies selected for a second straight year. 

We continue to supply our strategic partners with PV modules to support their development, testing and certification of new integrated PV products, including product testing by several branches of the U.S. military. We believe that our high-power density flexible solar modules enable new applications for solar power. By creating mutually beneficial partnerships and strategically penetrating the markets discussed above, we plan to develop the landscape of mobile solar power generation with advanced technology end products.

During 2021, the ASTI team further advanced product acceptance into the highly stringent space market with demonstrated solar module survivability under the guidance of NASA Marshal Space Flight Center (MSFC) MISSE X flight experiment on the International Space Station (ISS), advancing our Technology Readiness Level (TRL) to 6, with subsequent flights in 2022-23, both NASA and commercial, to achieve TRL 7. TRL 8 is commonly accepted as space qualified. Also during 2021, the ASTI team was able to utilize an ultra-thin lamination made from the coating material used during MISSE X to build custom modules for a customer to be tested for a future flight.

Competition

We have pivoted our strategic focus away from large scale utility projects of the traditional solar markets. We believe our thin film, monolithically integrated CIGS technology enables us to deliver sleek, lightweight, rugged, high performance solutions to serve these markets as competitors from other thin film and c-Si companies emerge. The landscape of thin film manufacturers encompasses a broad mix of technology platforms at various stages of development and consists of a number of medium and small companies.

The market for traditional, grid connected PV products is dominated by large manufacturers of c-Si technology, although thin film technology on glass has begun to emerge among the major players. We anticipate that while these large manufacturers may continue to dominate the market with their silicon-based products, thin film manufacturers will likely capture an increasingly larger share of the market, as is evident from the success of First Solar (CdTe) and Solar Frontier (CIGS), both among the top 20 producers worldwide. In 2019, crystalline silicon PV technology represented over 90% of global market revenue and production, with the balance captured by thin film. Approximately half of thin film production is CdTe production, with the other half being split between CIGS and a-Si.

We believe that our modules offer unique advantages. Their flexibility, low areal density (mass per unit area), and high specific power (power per unit mass) enable use on weight-sensitive applications, such as portable power, conformal aircraft

39

surfaces, high altitude long endurance (HALE) fixed wing and lighter than air (LTA) vehicles, and space applications that are unsuitable for glass-based modules. Innovative product design, customer focused development, and our rapid prototyping capability yield modules that could be integrated into virtually any product to create a source of renewable energy. Whether compared to glass based or other flexible modules, our products offer competitive advantages making them unique in comparison to competing products.

Research and Development and Intellectual Property

We intend to continue to invest in research and development in order to provide near term improvements to our manufacturing process and products, as well as to identify next generation technologies relevant to both our existing and potential new markets. During the nine months ended September 30, 2021 and full years 2020 and 2019 we incurred approximately $2,716,395, $1,165,193 and $1,310,948, respectively, in research and development costs, which include research and development incurred in relation to our government contracts, as well as manufacturing costs incurred while developing our product lines and manufacturing process.

Our technology was initially developed at ITN beginning in 1994. In early 2006, ITN assigned to us certain CIGS PV-specific technologies, and granted to us a perpetual, exclusive, royalty free, worldwide license to use these technologies in connection with the manufacture, development, marketing and commercialization of CIGS PV to produce solar power. In addition, certain of ITN’s existing and future proprietary process and control technologies, although nonspecific to CIGS PV, were assigned to us. ITN retained the right to conduct research and development activities in connection with PV materials, and we agreed to grant a license back to ITN for improvements to the licensed technologies and intellectual property outside of the CIGS PV field.

We protect our intellectual property through a combination of trade secrets and patent protections. We own the following patents and published patent applications:

Suppliers

We rely on several unaffiliated companies to supply certain raw materials used during the fabrication of our PV modules and PV integrated electronics. We acquire these materials on a purchase order basis and do not have long term purchase quantity commitments with the suppliers, although we may enter into such contracts in the future. We currently acquire all of our high temperature plastic from one supplier, although alternative suppliers of similar materials exist. We purchase component molybdenum, copper, indium, gallium, selenium and indium tin oxides from a variety of suppliers. We also currently are in the process of identifying and negotiating arrangements with alternative suppliers of materials in the United States and Asia.

The manufacturing equipment and tools used in our production process have been purchased from various suppliers in Europe, the United States and Asia. Although we have had good relations with our existing equipment and tools suppliers, we monitor and explore opportunities for developing alternative sources to drive our manufacturing costs down.

Employees

We currently have 52 full-time and 2 part-time employees.

Company History

We were formed in October 2005 from the separation by ITN of its Advanced Photovoltaic Division and all of that division’s key personnel and core technologies. ITN, a private company incorporated in 1994, is an incubator dedicated to the development of thin film, PV, battery, fuel cell and nanotechnologies. Through its work on research and development contracts for private and government entities, ITN developed proprietary processing and manufacturing know-how applicable to PV products generally, and to CIGS PV products in particular. Our company was established by ITN to commercialize its investment in CIGS PV technologies. In January 2006, ITN assigned to us all its CIGS PV technologies and trade secrets and granted to us a perpetual, exclusive, royalty free worldwide license to use certain of ITN’s proprietary process, control and design technologies in the production of CIGS PV modules. Upon receipt of the necessary government approvals in January 2007, ITN assigned government funded research and development contracts to us and also transferred the key personnel working on the contracts to us.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the notes to those consolidated financial statements appearing elsewhere in this prospectus. This discussion and analysis contains statements of a forward-looking nature relating to future events or our future financial performance. As a result of many factors, our actual results may differ materially from those anticipated in these forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

Significant Trends, Uncertainties and Challenges

We believe the significant trends, uncertainties and challenges that directly or indirectly affect our financial performance and results of operations include:

Remediation of Material Weaknesses: At December 31, 2020 and March 31, 2021, we concluded that there were material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. See Management’s Discussion and Analysis--Remediation of Material Weaknesses. The Company executed the following steps to remediate the aforementioned material weaknesses in its internal control over financial reporting:

44

The Company engaged an external resource with the technical expertise to assist in documenting and testing internal controls under Section 302 and 404 of the Sarbanes Oxley Act of 2002.

Basis of Presentation: The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We have identified the policies below as critical to our business operations and to the understanding of our financial results:

Significant Accounting Policies

Inventories: All inventories are stated at the lower of cost or net realizable value, with cost determined using the weighted average method. Inventory balances are frequently evaluated to ensure they do not exceed net realizable value. The computation for net realizable value takes into account many factors, including expected demand, product life cycle and development plans, module efficiency, quality issues, obsolescence and others. Management's judgment is required to determine reserves for obsolete or excess inventory. If actual demand and market conditions are less favorable than those estimated by management, additional inventory write downs may be required.

Impairment of Long-lived assets: We analyze our long-lived assets (property, plant and equipment) and definitive-lived intangible assets (patents) for impairment, both individually and as a group, whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. Events that might cause impairment would include significant current period operating or cash flow losses associated with the use of a long-lived asset or group of assets combined with a history of such losses, significant changes in the manner of use of assets and significant negative industry or economic trends. An undiscounted cash flow analysis is calculated to determine if an impairment exists. If an impairment is determined to exist, any related loss is calculated using the difference between the fair value and the carrying value of the assets.

Convertible Preferred Stock: The Company evaluates its preferred stock instruments under FASB ASC 480, “Distinguishing Liabilities from Equity” to determine the classification, and thereby the accounting treatment, of the instruments. Please refer to Note 15 to the consolidatedfinancial statements as of December 31, 2020 and 2019 for further discussion on the classification of each instrument.

Derivatives: The Company evaluates its financial instruments under FASB ASC 815, “Derivatives and Hedging” to determine whether the instruments contain an embedded derivative. When an embedded derivative is present, the instrument is evaluated for a fair value adjustment upon issuance and at the end of every period. Any adjustments to fair value are treated as gains and losses in fair values of derivatives and are recorded on the Statement of Operations. Please refer to Notes 10 and 12 to the consolidatedfinancial statements as of December 31, 2020 and 2019 for further discussion on the embedded derivatives of each instrument.

Paycheck Protection Program Loan: The Company has elected to account for the forgivable loan received under the Paycheck Protection Program (“PPP”) provisions of the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act as a debt instrument and to accrue interest on the outstanding loan balance. Additional interest at a market rate (due to the stated interest rate of the PPP loan being below market) is not imputed, as the transactions where interest rates prescribed by governmental agencies are excluded from the scope of accounting guidance on imputing interest. The proceeds from the loan will remain recorded as a liability until either (1) the loan is, in part of wholly, forgiven and the Company has been legally

45

released or (2) the Company repays the loan to the lender. On September 4, 2021, the Company received notification from Vectra Bank Colorado that the Small Business Administration has forgiven the PPP loan and the liability was recognized as other income.

Revenue Recognition:

Product revenue. We recognize revenue for the sale of PV modules and other equipment at a point in time following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. For module and other equipment sales contracts that contain multiple performance obligations, we allocate the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognize the related revenue as control of each individual product is transferred to the customer.

Milestone revenue. Each milestone arrangement is a separate performance obligation. The transaction price is estimated using the most likely amount method and revenue is recognized as the performance obligation is satisfied through achieving manufacturing or cost targets and engineering targets.

Government contract revenue. Revenue from government research and development contracts is generated under terms that are cost plus fee or firm fixed price. We generally recognize this revenue over time using cost-based input methods, which recognize revenue and gross profit as work is performed based on the relationship between actual costs incurred compared to the total estimated costs of the contract. In applying cost-based input methods of revenue recognition, we use the actual costs incurred relative to the total estimated costs to determine our progress towards contract completion and to calculate the corresponding amount of revenue to recognize.

Cost based input methods of revenue recognition are considered a faithful depiction of our efforts to satisfy long-term government research and development contracts and therefore reflect the performance obligations under such contracts. Costs incurred that do not contribute to satisfying our performance obligations are excluded from our input methods of revenue recognition as the amounts are not reflective of our transferring control under the contract. Costs incurred towards contract completion may include direct costs plus allowable indirect costs and an allocable portion of the fixed fee. If actual and estimated costs to complete a contract indicate a loss, provision is made currently for the loss anticipated on the contract.

Research, Development and Manufacturing Operations Costs: Research, development and manufacturing operations expenses include: (1) technology development costs, which include expenses incurred in researching new technology, improving existing technology and performing federal government research and development contracts, (2) product development costs, which include expenses incurred in developing new products and lowering product design costs, and (3) pre-production and production costs, which include engineering efforts to improve production processes, material yields and equipment utilization, and manufacturing efforts to produce saleable product. Research, development and manufacturing operations costs are expensed as incurred, with the exception of costs related to inventoried raw materials, work-in-process and finished goods, which are expensed as Cost of revenue as products are sold. 

Share-Based Compensation:  We measure and recognize compensation expense for all share-based payment awards made to employees, officers, directors, and consultants based on estimated fair values. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service period in our statements of operations included herein. Share-based compensation is based on awards ultimately expected to vest, reduced by estimated forfeitures. Forfeitures are estimated at the time of grant and revised, as necessary, in subsequent periods if actual forfeitures differ from those estimates. For purposes of determining estimated fair value of share-based payment awards on the date of grant, we use the Black-Scholes option-pricing model (“Black-Scholes Model”) for option awards. The Black-Scholes Model requires the input of highly subjective assumptions. Because our employee stock options may have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models may not provide a reliable single measure of the fair value of our employee stock options. Management will continue to assess the assumptions and methodologies used to calculate estimated fair value of share-based compensation. Circumstances may change and additional data may become available over time, which result in changes to these assumptions and methodologies, which could materially impact our fair value determination. We estimate the fair value of our restricted stock awards at our stock price on the grant date.

The accounting guidance for share-based compensation may be subject to further interpretation and refinement over time. There are significant differences among option valuation models, and this may result in a lack of comparability with other companies that use different models, methods and assumptions. If factors change and we employ different assumptions in the

46

accounting for share-based compensation in future periods, or if we decide to use a different valuation model, the compensation expense we record in the future may differ significantly from what we have recorded in the current period and could materially affect our loss from operations, net loss and net loss per share.

Earnings per Share: Earnings per share (“EPS”) are the amount of earnings attributable to each share of common stock. Basic EPS has been computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. Income available to common stockholders has been computed by deducting dividends accumulated for the period on cumulative preferred stock (whether or not earned) from net income. Diluted earnings per share has been computed by dividing net income adjusted on an if-converted basis for the period by the weighted average number of common shares and potentially dilutive common share outstanding (which consist of options and convertible securities using the treasury stock method or the if-converted method, as applicable, to the extent they are dilutive).

Use of Estimates:  The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recently Issued Accounting Standards

In August 2020, the FASB issued ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity s Own Equity. ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective for smaller reporting companies for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Management has not yet evaluated the impact that the adoption of ASU 2020-06 will have on the Company’s consolidated financial statement presentation or disclosures.

Other new pronouncements issued but not effective are not expected to have a material impact on the Company’s consolidated financial statements.

Results of Operations

Comparison of the Years EndedDecember 31, 2020and2019

Revenues. Our revenues were $66,613 for the year ended December 31, 2020 compared to $638,380 for the year ended December 31, 2019, a decrease of $571,767. The decrease in sales is due primarily to significantly reduced operations during the year ended December 31, 2020. The Company was in a dormant status for the most part of the year as the focus in 2020 was to recapitalize and restructure the Company’s balance sheet. The intensification of the COVID-19 pandemic since March 2020 also significantly impacted our restructuring effort, thereby delaying our ability to restart our operations in a timely manner.

Cost of revenues. Our cost of revenues for the year ended December 31, 2020 was $174,588 compared to $490,755 for the year ended December 31, 2019, a decrease of 64%. The decrease in cost of revenues is mainly due to the decrease in materials and labor costs as a result of a decrease in production for the year ended December 31, 2020 compared to 2019. Cost of revenues for the year ended December 31, 2020 is comprised primarily of direct labor and overhead.

Research, development and manufacturing operations. Research, development and manufacturing operations costs were $1,165,193 for the year ended December 31, 2020, compared to $1,310,948 for the year ended December 31, 2019, a decrease of 11%. The decrease in cost is due primarily to reduced operations during the year ended December 31, 2020.

47

Research, development and manufacturing operations costs include costs incurred for product development, pre-production and production activities in our manufacturing facility.
