Overview

We are a medical technology company focused on developing and commercializing products utilizing our proprietary designed acoustic shockwave technology platform referred to as RAP. We are a pre-revenue stage company with our first product preparing for launch for the removal of tattoos and the reduction of cellulite. Our RAP device uses rapid pulses of designed acoustic shockwaves to disrupt cellular structures in the dermal and subdermal tissue. The uniqueness of our designed shockwave allows us to target the differential in stiffness between cellular structures and generate a shearing effect that we believe represents a platform technology potentially useful in tattoo removal, cellulite treatment, fibrotic scar treatment and


                                       15

--------------------------------------------------------------------------------

Table of Contents other indications. We believe the high repetition rate, rapid rise and fall of the wave, and significant peak pressure delivered in a non-focused manner make our shockwave significantly different from other available shockwave technologies. Importantly, our technology allows the disruption of targeted structures within the skin with only minimal discomfort and without additional treatment-related downtime for tattoo removal or any downtime for cellulite treatment.

We received clearance for our initial device from the U.S. Food and Drug Administration ("FDA") on May 24, 2019 allowing our device to be used as an accessory to the 1064 nm Q-switched laser for black ink tattoo removal on patients with skin tones on the Fitzpatrick Skin Type scale between I and III. When used in conjunction with existing lasers for tattoo removal, our technology allows a doctor to treat a patient multiple times in a single office visit and significantly reduces the number of office visits required to remove a tattoo, allowing a dramatic acceleration of the tattoo removal process. In January 2021, we received additional clearance from the FDA for temporary improvement in the appearance of cellulite. Used on a stand-alone basis, our technology generates, on average, an approximate 30% reduction in the cellulite severity score ("CSS") for subjects in a single treatment without breaking the skin. RAP cellulite treatments cause only minimal discomfort, do not require anesthesia and do not result in any significant treatment-related side effects or patient downtime.

We plan to launch our RAP device for tattoo removal and cellulite reduction in the second quarter of 2021 initiating the first shipments into approximately 25 select cosmetic dermatology and plastic surgery offices. We expect to generate revenue from both the initial sale of the device and from the recurring sales of disposable cartridges that are required by the device to deliver the various therapies. We refer to this as our "razor and blade" recurring revenue model. Cartridges are designed to be specific to the intended indication (for example, tattoo cartridges are different from cellulite cartridges) and each treatment session requires one or more cartridges. We expect that one tattoo cartridge will facilitate up to four standard laser treatment passes in a single office visit for the average-sized tattoo (about the size of a deck of playing cards). Therefore, a patient with an average-sized tattoo that requires three office visits will require the use of three cartridges. One cellulite cartridge will treat one leg and buttocks area in a single session for an average patient. As such, most cellulite patients will require two cartridges for their initial treatment of both legs and buttocks. We anticipate that patients may benefit from a second maintenance treatment using a single cartridge across the full treatment area, but have not yet demonstrated this in clinical trials.

We also have ongoing clinical programs in several indications, which, if successful, will allow us to expand commercialization of our products into additional markets. As a stand-alone device, we believe RAP has the potential to reduce the effects of fibrosis and stimulate beneficial fibroblast behavior. This capability enables the targeting of fibrotic (keloid and hypertrophic) scars, as well as smoothing and tightening skin. Importantly, we are planning to initiate additional proof-of-concept clinical trials of our RAP device in the treatment of keloid and hypertrophic scars as well as the improvement of skin laxity in 2021. We also intend to pursue regulatory approval in international markets and we are currently developing a regulatory strategy for these additional markets. We recently announced results from a study in mice demonstrating the ability of RAP to significantly reduce liver fibrosis, further validating the scientific basis for RAP's mechanism of action and potentially widening the range of indications for which RAP may be suitable. Our technology has not been cleared by the FDA for the treatment of scars or fibrosis.

Commercial upgrades to our Generation 2.0 device to improve usability were subsequently approved through a Special 510(k) in March 2020. This improved device was utilized in our recently completed pivotal cellulite trial, the data from which was included in the 510(k) pre-market application of our Generation 2.0 device for the temporary reduction in the appearance of cellulite filed on June 30, 2020 and approved in January of 2021. Further commercial upgrades to our Generation 2.0 device were approved through a Special 510(k) in April of 2021 clearing the regulatory path to the launch of our first commercial devices. We also intend to secure regulatory approval in international markets and are currently developing a regulatory strategy for these markets.

Our ongoing research and development activities are primarily focused on finalizing the commercial device and cartridge design for tattoo removal and cellulite reduction and then developing our system and treatment head for additional indications. In addition to these development activities, we are exploring additional uses of RAP technology for the dermatology, plastic surgery and aesthetic markets.

The medical technology and aesthetic product markets are highly competitive and dynamic and are characterized by rapid and substantial technological development and product innovations. We will compete with many other technologies for consumer demand. Further, the aesthetic industry in which we will operate is particularly vulnerable to economic trends. The decision to undergo a procedure from our systems will be driven by consumer demand. Procedures performed using our systems will be elective procedures, the cost of which must be borne by the patient and are not reimbursable through government or private health insurance. In times of economic uncertainty or recession, individuals often reduce the amount of money that they spend on discretionary items, including aesthetic procedures. The general economic difficulties being experienced and the lack of availability of consumer credit for some of our customers' patients could adversely affect the markets in which we will operate.

Recent Developments

On April 27, 2021, the FDA cleared our special 510(k) application submitted on March 31, 2021 for modifications to our device planned for commercial launch.

On March 9, 2021, we announced that we had initiated a second pre-clinical study in animals for potential treatment of liver fibrosis intending to validate the first animal study that demonstrated positive results for the potential treatment of liver fibrosis.

On February 23, 2021, we announced that a pre-clinical study in animals demonstrated positive results for the potential treatment of liver fibrosis. Validated laboratory and histological assessments in a mouse model demonstrated that RAP therapy reduced the effects of induced liver fibrosis 7-days following completion of carbon tetrachloride (CCL4) induction by 42%. In addition, post treatment histology slides stained with picrosirius red ("PSR") showed a lower percentage of fibrosis from a single 2-minute RAP treatment compared to the Control group.

On February 1, 2021, we announced that the FDA had cleared our RAP technology for the short-term improvement in the appearance of cellulite.

On January 26, 2021, we announced we had entered into a collaboration with the US Navy to conduct a multi-treatment proof-of-concept clinical study to evaluate the safety and efficacy of multiple treatments with Soliton's RAP device for the improvement in the appearance of fibrotic scars.

Agreement and Plan of Merger

On May 8, 2021, the Company entered into the Merger Agreement with AbbVie Merger Sub, under which Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation and a wholly-owned subsidiary of AbbVie.

Upon the closing of the Merger, each outstanding share of Company common stock, other than shares owned by the Company, AbbVie or Merger Sub (which will be cancelled) and shares with respect to which appraisal rights are properly exercised and not withdrawn under Delaware law, will automatically be converted into the right to receive $22.60 in cash, without interest (the "Merger Consideration").

Each stock option outstanding and unexercised immediately prior to the effective time of the Merger (the "Effective Time") will be converted into the right to receive a cash payment, without interest, in an amount equal to the excess of the Merger Consideration over the per share exercise price that would be due in cash upon exercise of such stock option. Each restricted stock unit award outstanding immediately prior to the Effective Time will be converted into the right to receive a cash payment, without interest, in an amount equal to the Merger Consideration. Each warrant to purchase Company common stock outstanding and unexercised immediately prior to the Effective Time will be converted into the right to receive a cash payment, without interest, in an amount equal to the excess of (i) the number of shares of common stock subject to the warrant, multiplied by the Merger Consideration over (ii) the number of shares of common stock subject to the warrant, multiplied by the per share exercise price of such warrant.

The consummation of the Merger is subject to certain customary closing conditions, including (i) the adoption of the Merger Agreement by the holders of a majority of the outstanding shares of the Company's common stock (the "Stockholder Approval"), (ii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and (iii) that no judgment or law is in effect that enjoins, makes illegal or otherwise prohibits the consummation of the Merger. Moreover, each party's obligations to consummate the Merger are subject to certain other conditions, including (a) the accuracy of the other party's representations and warranties (subject to certain materiality exceptions), (b) the other party's compliance in all material respects with its obligations under the Merger Agreement, and (c) in the case of AbbVie and Merger Sub only, (i) the absence of any pending claim, proceeding or other action by a governmental authority that seeks to prevent, prohibit or make illegal the consummation of the Merger or materially limit AbbVie's ability to own, control, direct, manage or operate the Company and (ii) the absence of any effect, change, event, development or occurrence that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect (as defined in the Merger Agreement) that is continuing. Subject to the satisfaction of the closing conditions, closing of the Merger is expected to occur in the second half of 2021.



                                       17

--------------------------------------------------------------------------------

Table of Contents The Merger Agreement contains representations and warranties and covenants of the parties customary for a transaction of this nature. Until the earlier of the termination of the Merger Agreement and the Effective Time, the Company has agreed to operate its business in the ordinary course of business in all material respects and has agreed to certain other operating covenants and to not take certain specified actions prior to the consummation of the Merger, as set forth more fully in the Merger Agreement. The Company has also agreed to convene and hold a meeting of its stockholders for the purpose of obtaining the Stockholder Approval. In addition, the Merger Agreement requires that, subject to certain exceptions, the Board recommend that the Company's stockholders approve the Merger Agreement.

The Merger Agreement contains certain termination rights for the Company and AbbVie, including, among others, the right of (1) the Company to terminate the Merger Agreement in order to enter into an agreement providing for a Superior Proposal (subject to the Company's compliance with certain obligations under the Merger Agreement related to such Superior Proposal and such termination) and (2) AbbVie to terminate the Merger Agreement if the Board changes its recommendation with respect to the Merger Agreement. The Merger Agreement also provides that under specified circumstances, including in the event of termination as described in (1) or (2) above, the Company will be required to pay AbbVie a termination fee of $18,625,000.

In connection with a termination of the Merger Agreement under specified circumstances involving failure to obtain clearance under the HSR Act to consummate the Merger (or failure to remove certain legal restraints, or to resolve certain pending claims or proceedings, arising under antitrust laws with respect to the Merger) within six months from the date of the Merger Agreement, subject to two extensions of three months each (provided other closing conditions are satisfied), or involving a non-appealable legal restraint of the Merger arising under antitrust laws, AbbVie may be required to pay the Company a reverse termination fee of up to $20,000,000.

Research and development. Research and development expenses increased by $0.3
million compared to the same period in 2020, mainly due to increases in expenses
for salaries and related costs of $0.2 million and engineering related costs of
$0.1 million.
Sales and marketing. Sales and marketing expenses increased by $0.7 million
compared to the same period in 2020, largely attributed to increases in expenses
for salaries and related costs of $0.3 million, social media development of $0.2
million, stock-based compensation of $0.1 million, and other expenses totaling
$0.1 million.
General and administrative. General and administrative expenses increased by
$1.0 million compared to the same period in 2020. This increase was primarily
due to increases in expenses for salaries and related costs of $0.3 million,
board related fees of $0.2 million, legal expenses of $0.2 million, stock-based
compensation of $0.2 million, and information technology of $0.1 million.

Liquidity and Capital Resources
On March 31, 2021, we had $26.1 million of cash and cash equivalents and $0.2
million in restricted cash representing a letter of credit benefiting our
contract manufacturer.
We will not generate revenue until we have completed the commercialization of
our RAP units and initiated sales of the units. We expect to continue to invest
in our research and development efforts to support our current initiatives.

We estimate our current cash, cash equivalents and restricted cash resources of $26.3 million at March 31, 2021 is sufficient to fund our operations into the third quarter of 2022 but not beyond. We anticipate incurring operating losses for the next several years as we complete the development of our products, seek requested regulatory clearances to market such products and support the commercial launch of our products. These factors raise uncertainties about our ability to fund operations in future years. If we need to raise additional capital in order to continue to execute our business plan, including obtaining additional regulatory clearance for our products currently under development and commercializing and generating revenues from products under development, there is no assurance that additional financing will be available when needed or that management will be able to obtain financing on terms acceptable to us. A failure to raise sufficient capital could adversely impact our ability to achieve our intended business objectives and meet our financial obligations as they become due and payable.

The COVID-19 global pandemic has resulted in travel restrictions and temporary shut-downs of non-essential businesses in many states in the United States. We are able to remain open but have required our employees to work from home for a portion of the work week. Due to many uncertainties, we are unable to estimate the pandemic's financial impact or duration at this time.
