Overview

We are a pre-revenue medical device company focused on the design, development and commercialization of innovative insulin pumps using modernized technology to increase pump adoption in the diabetes marketplace. Through the creation of a novel two part patch pump, we seek to fundamentally alter the trade-offs between cost and complexity and access to the higher standards of care that presently-available insulin pumps provide. By simplifying and streamlining the user experience from introduction, prescription, reimbursement, training and day-to-day use, we seek to expand the wearable insulin delivery device market beyond the highly motivated "super users" and expand the category into the mass market. The product seeks to serve both the type 1 and the rapidly growing, especially in terms of device adoption, type 2 diabetes markets. In January 2024, we submitted a 510(k) premarket notification to the United States Food and Drug Administration (the "FDA") for our initial product, our MODD1, and, in September 2024, we received FDA clearance to market and sell our MODD1 pump in the United States. In August 2025, we announced the first human use of our MODD1 pump delivering insulin to a human patient. In addition, in August 2025, we announced our next-generation patch pump, branded as Pivot. We submitted a 510(k) premarket notification to the FDA for our Pivot product on November 13, 2025. On April 9, 2026, we received FDA clearance to market and sell our Pivot product in the United States. We intend to initiate our commercial launch with the Pivot product now that the required regulatory approval from the FDA has been received. We are actively working to i) prepare to commence commercialization of our Pivot product, ii) obtain regulatory clearance to market and sell our Pivot product in foreign jurisdictions, iii) improve the manufacturability and usability of our Pivot product and iv) develop new pump products.

Historically, we have financed our operations principally through private placements and public offerings of our common stock and warrants and sales of convertible promissory notes. Based on our current operating plan, substantial doubt about our ability to continue as a going concern for a period of at least one year from the date that the financial statements included in Item 1 of this Report are issued exists. Our ability to continue as a going concern depends on our ability to raise additional capital, through the sale of equity or debt securities, to support our future operations. If we are unable to secure additional capital, we will be required to curtail our research and development initiatives and take additional measures to reduce costs. We have provided additional disclosure in Note 1 to the consolidated financial statements in Item 1 of our most recently filed Annual Report.

We do not currently have revenues to generate cash flows to cover operating expenses. Since our inception, we have incurred operating losses and negative cash flows in each year due to operating expenses and capital expenditures incurred to conduct our operations. We incurred net losses of approximately $21.9 million for the nine months ended December 31, 2025 and approximately $18.8 million for the year ended March 31, 2025, and we had an accumulated deficit of approximately $106.6 million as of December 31, 2025. These and prior year losses have resulted in significant negative cash flows and have necessitated that we raise substantial amounts of additional capital during this period. This raises significant doubt about our ability to continue as a going concern, which was also expressed by our independent registered public accounting firm in its report on our consolidated financial statements for the year ended March 31, 2025. Our ability to continue as a going concern depends on our ability to raise additional capital, through the sale of equity or debt securities to support our future operations.

Our Products

Instead of building complex, bespoke, and difficult to manufacture and maintain pumping and control systems, we began with the technology and the user in mind. Using proprietary methods of insulin measurement, we were able to eschew complex mechanisms and instead built our pump products, using only parts from high volume consumer electronics manufacturing lines, breaking the cost vs functionality curve that has existed in the insulin pump space and representing the first truly modern insulin pump design. We consider this to be a new kind of product for a new kind of patient.

We have moved our production line for our Pivot product to our manufacturing partner, Phillips Medisize, a Molex company, a large tier-one medical device manufacturer, which will manage and operate our production to produce products for human use. We believe that Phillips Medisize will be able to rapidly scale our production to higher volumes at lower cost. We continue to devote substantial time and resources, including exhibiting at major diabetes conferences, to better understand the needs and preferences of Almost Pumpers and the specific patient/provider/payor requirements to motivate change from MDI therapy. By making the bolus delivery at meals simple, we believe we will drive improved health outcomes.

S-1

Our Pivot product has several distinguishing features:

1. The pump has a simple button to press to deliver insulin as the patient requires it. The electronic pump uses a simple motor for rotating a cam to motivate the insulin into the patient along with low power Bluetooth and near-field communication (NFC) chips to optionally allow the patient to communicate with a smart phone, tablet, or other mobile computing device.

2. The pump snaps together with a three-day disposable cartridge, which the patient fills with insulin for delivery. It includes a simple coin cell, which allows it to run through the 80-hour life of the cartridge.

3. The infusion set is built into the adhesive pad that the pump attaches to and the needle can be safely removed and discarded by the user after application. Despite this true patch form factor, the pump is removable by the user during the three days of wear.

The system will deliver a small continuous rate called a basal that will provide approximately 50% of the total daily dose required, and the user will use the on-pump button to administer boluses, typically before and after meals. The objective is to make the product simple to acquire and take home, simple to learn and most importantly, simple to use and live with, to expand the pump market, drive adoption and, ultimately, improve clinical outcomes.

S-2

Commercialization Strategy

We plan to commercialize our Pivot product line using a highly differentiated go-to-market strategy. Generally, current pumps are marketed by a large, direct sales force to end users directly, and the manufacturer provides all training and support, as the current training reimbursement offered by insurance providers is inadequate to motivate clinicians to provide such training to patients. We intend to employ a different strategy and utilize i) distributors to target the daily insulin users who are still managed by a primary care physician and ii) a small direct sales force to directly engage with diabetes educator practices. Specifically, our direct sales force will engage with larger diabetes educator practices, which currently prescribe a high volume of pumps and deliver a consultative message focused on those users that indicate a desire to use a pump but have rejected all of the currently available options. We engaged Seagrove to conduct a survey of physicians and diabetes educators, and the resulting data suggested that approximately 25% of multiple daily injectors could be receptive to our offering. We believe that the modest 30-minute training requirement for our product, combined with the more limited feature set for our Pivot product, will incentivize nurse practitioners to identify and train new users who have not been offered pumps before. This would also allow us to offer virtual or second level training support and not require us to be the primary training provider.

We received FDA clearance for our Pivot product on April 9, 2026, and we plan to launch our Pivot product during the quarter ending June 30, 2026. We believe the new integrated insulin-delivery set will offer improved user experience, while reducing our production costs

We have also begun the process of obtaining Conformite Europeenne, or CE, mark clearance for our Pivot design, which would allow us to market and sell in European markets. We expect to obtain CE mark clearance by the first quarter of 2027. Our initial strategy to address European markets is to partner with distributors to bring the Pivot to market in those countries that accept the CE mark and have acceptable reimbursement. We believe that the combination of our patch pump form factor, lower cost at scale and lower training burden is well suited for European markets where there are very few physicians or nurses available to provide training. This would allow the Pivot to gain rapid adoption in areas where pump penetration is currently much lower than in the United States. We will target other select international markets using the same approach.

We believe the combination of these differentiated approaches will enable us to take reasonable initial market share, while not incurring the significant overhead cost of existing commercialization strategies employed by the incumbents, where competition for users is intense.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks described below, together with other information in this prospectus supplement, the accompanying prospectus and the information and documents incorporated by reference. You should also consider the risks, uncertainties and assumptions discussed under the heading "Risk Factors" included in our most recent Annual Report on Form 10-K and the subsequent reports that we file with the SEC which are on file with the SEC and are incorporated herein by reference, and which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. If any of these risks actually occur, our business, financial condition, results of operations or cash flow could be adversely effected. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business. Please also read carefully the section below entitled "Special Note Regarding Forward-Looking Statements."

Risks Related to Our Business and Securities

We might not be able to continue as a going concern.

Our condensed consolidated financial statements as of December 31, 2025 have been prepared under the assumption that we will continue as a going concern twelve months from the date of this prospectus supplement. At December 31, 2025, we had cash and cash equivalents of $2.9 million and an accumulated deficit of approximately $106.6 million. In March 2026, we closed a public offering for net proceeds of approximately $10.9 million. Even with these proceeds, we do not believe that our cash and cash equivalents will be sufficient to fund our operations for the period of 12 months from the date of this prospectus supplement, and we will need to raise additional capital. As a result of our expected operating losses and cash burn for the foreseeable future and recurring losses from operations, if we are unable to raise sufficient capital through additional debt or equity arrangements, there will be uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt as to our ability to continue as a going concern. If we cannot continue as a viable entity, our stockholders would likely lose most or all of their investment in us. If we are unable to generate sustainable operating profit and sufficient cash flows, then our future success will depend on our ability to raise capital. We intend to seek additional financing and evaluate financing alternatives in order to meet our cash requirements for the foreseeable future. We cannot be certain that raising additional capital, whether through selling additional debt or equity securities or obtaining a line of credit or other loan, will be available to us or, if available, will be on terms acceptable to us. If we issue additional securities to raise funds, these securities may have rights, preferences, or privileges senior to those of our common stock, and our current stockholders may experience dilution. If we are unable to obtain funds when needed or on acceptable terms, we may be required to curtail our current product development programs, cut operating costs, forego future development and other opportunities or even terminate our operations.

If we are unable to satisfy the continued listing requirements of the Nasdaq, our common stock could be delisted and the price and liquidity of our common stock may be adversely affected.

Our common stock may lose value and could be delisted from Nasdaq due to several factors or a combination of such factors. While our common stock is currently listed on Nasdaq, we can give no assurance that we will be able to maintain compliance with the continued listing requirements of Nasdaq, including, but not limited to, the corporate governance requirements, the minimum closing bid price requirement or the minimum equity requirement. If we fail to maintain compliance with any such continued listing requirement, there can also be no assurance that we will be able to regain compliance with any such continued listing requirement in the future or that our common stock will not be delisted in the future.

On June 30, 2025, we received a letter from the Listing Qualifications Staff of Nasdaq indicating that, based upon the closing bid price of our common stock for the 30 consecutive business days ending on June 27, 2025, we no longer meet the requirement to maintain a minimum bid price of $1 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have been provided a period of 180 calendar days, or until December 29, 2025, in which to regain compliance.

On December 23, 2025, we submitted a request to Nasdaq for an additional 180-day period (the "Second Compliance Period") to provide additional time for us to demonstrate compliance with the minimum bid price requirement. In such request, we communicated that we intend to regain compliance during the Second Compliance Period by effecting a reverse stock split. On December 30, 2025, we received written notification from the Listing Qualifications Department of Nasdaq, granting our request for a 180-day extension to regain compliance with the minimum bid price requirement. We were granted until June 29, 2026 to meet the requirement. On March 31, 2026, we effected a one (1)-for-thirty (30) reverse stock split of our Common Stock. On April 15, 2026, we were notified by Nasdaq that we had regained compliance with Nasdaq Marketplace Rule 5550(a)(2), and Nasdaq considers the matter closed.

S-6

There can be no assurance that we will be able to regain compliance with the minimum bid price requirement, maintain compliance with the other continued listing requirements of Nasdaq, or that our common stock will not be delisted in the future. If we were to be delisted, we would expect our common stock to be traded in the over-the-counter market which could adversely affect the liquidity of our common stock. Additionally, we could face significant material adverse consequences, including:

a limited availability of market quotations for our common stock;
a decreased ability to issue additional securities or obtain additional financing in the future;
reduced liquidity for our stockholders;
potential loss of confidence by customers, collaboration partners and employees; and
loss of institutional investor interest.

In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq minimum bid price requirement, or prevent future non-compliance with Nasdaq's listing requirements.

Risks Related to This Offering

After this offering, we will need to raise additional capital in the future to execute our business plan.

We expect the net proceeds to us from this offering will approximate $2.9 million. Upon closing of this offering, we expect to have cash and cash equivalents of approximately $8.5 million. After the closing of this offering, we believe we will have adequate funds to operate our business for at least the next four months. We will require additional funding to commercialize our pump product and bring it to market.

We cannot be certain that additional capital, whether through selling additional debt or equity securities or obtaining a line of credit or other loan, will be available to us or, if available, will be on terms acceptable to us. If we issue additional securities to raise funds, these securities may have rights, preferences, or privileges senior to those of our common stock, and our current stockholders may experience dilution. If we are unable to obtain funds when needed or on acceptable terms, we may be required to curtail our current product development programs, cut operating costs, forego future development and other opportunities or even terminate our operations.

S-7

As we have broad discretion in how we use the proceeds from this offering, we may use the proceeds in ways with which you disagree.

We have not allocated the net proceeds from this offering for any specific purpose, except as generally set forth under "Use of Proceeds." As set forth therein, our management will have significant flexibility in applying the net proceeds of this offering. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used in ways you would agree with or ways which are likely to increase the value of your investment. Because of the number and variability of factors that will determine our use of our net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. It is possible that the net proceeds will be invested in a way that does not yield a favorable, or any, return for our company or your investment. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flow.

You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase.

As of December 31, 2025, our net tangible book value was approximately $5.9 million, or approximately $2.27 per share of common stock. As the effective price per share of our common stock being offered in this offering is substantially higher than the net tangible book value per share of our common stock, you will suffer substantial dilution with respect to the net tangible book value of the common stock you purchase in this offering. Based on the offering price of $4.50 per share of common stock being sold in this offering, and our net tangible book value per share as of December 31, 2025, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of $2.87 per share with respect to the net tangible book value of the common stock. See the section titled "Dilution" below for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering.

You will likely experience future dilution as a result of future equity offerings and other issuances of our common stock or other securities. In addition, this offering and future equity offerings and other issuances of our common stock or other securities may adversely affect the price of our common stock.

In order to raise additional capital, in the future, we expect to offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock (such as warrants, convertible debt or preferred stock) at prices that may not be the same as the price per share in this offering. We may not be able to sell shares of common stock or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares of common stock or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or securities convertible into common stock in future transactions may be higher or lower than the price per share in this offering. In addition, the sale of shares of common stock in this offering and any future sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could adversely affect the price of our common stock. We cannot predict the effect, if any, that market sales of those shares of common stock or the availability of those shares of common stock for sale will have on the market price of our common stock.

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $2.9 million, based on the offering price of $4.50 per share of common stock and after deducting placement agent fees and estimated offering expenses payable by us.

We currently expect to use the net proceeds from this offering primarily for working capital, capital expenditures and general corporate purposes.

Our expected use of the net proceeds from this offering represents our current intentions based upon our present plans and business conditions. As a result, our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds of this offering. In addition, we might decide to postpone or not pursue these certain of these activities if the net proceeds from this offering and the other sources of cash are less than, or do not last as long as, expected. We have no current understandings, agreements or commitments for any material acquisitions or licenses of any products, businesses or technologies.

Pending their use, we plan to invest the net proceeds from this offering in high-quality, short-term interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

S-10

DIVIDEND POLICY

We have never declared or paid any cash dividend on our capital stock. We do not anticipate paying any cash dividends in the foreseeable future and we intend to retain all of our earnings, if any, to finance our growth and operations and to fund the expansion of our business. Payment of any dividends will be made in the discretion of our board of directors, after its taking into account various factors, including our financial condition, operating results, current and anticipated cash needs and plans for expansion. Any dividends that may be declared or paid on our common stock, must also be paid in the same consideration or manner, as the case may be, on our shares of preferred stock, if any.

S-11

DILUTION

If you invest in our securities, your interest will be diluted immediately to the extent of the difference between the offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock immediately after giving effect to this offering.

As of December 31, 2025, our historical net tangible book value, which represents our total tangible assets less total liabilities, was approximately $5.9 million, or $2.27 per share of common stock. Historical net tangible book value per share represents the amount of our total tangible assets reduced by total liabilities, divided by 2,590,118, the number of shares of common stock outstanding on December 31, 2025.

After giving effect to the sale of the securities, at the offering price of $4.50 per share of our common stock, after deducting estimated placement agent fees and offering expenses payable by us, our net tangible book value as of December 31, 2025 would have been $8.8 million or $1.63 per share of common stock. This amount represents an immediate decrease in net tangible book value of $0.64 per share to our existing stockholders. Investors purchasing our common stock in this offering will have paid $2.87 more than the as-adjusted net tangible book value per share of common stock after this offering.

The following table illustrates this dilution on a per share basis:

Offering price per share $ 4.50
Historical net tangible book value per share as of December 31, 2025 $ 2.27
Decrease in net tangible book value per share attributable to new investors $ (0.64 )
Net tangible book value per share after the offering 1.63
Dilution per share to new investors $ 2.87

The number of shares of our common stock to be outstanding after this offering is based on 2,590,118 shares of our common stock outstanding as of December 31, 2025, and excludes:

308 shares of common stock issuable attributable to a warrant inducement offering effected in September 2025;
244,670 shares of common stock issuable upon the exercise of outstanding stock options, which options have a weighted average exercise price of $71.43 per share;
1,388 shares of common stock issuable upon the vesting of restricted stock units;
98,523 shares of common stock available for future issuance under the Amended and Restated 2017 Equity Incentive Plan, as amended (the "2017 Equity Incentive Plan");
233,315 shares of common stock issuable upon the exercise of warrants outstanding at $13.50 per share;
32,664 shares of common stock issuable upon the exercise of warrants outstanding at $13.86 per share;
108,258 shares of common stock issuable upon the exercise of warrants outstanding at $25.20 per share;
29,155 shares of common stock issuable upon the exercise of warrants outstanding at $0.42 per share;
63,501 shares of common stock issuable upon the exercise of warrants dated March 25, 2025 at $33.60 per share;
12,718 shares of common stock issuable upon the exercise of warrants outstanding at $56.25 per share;
16,133 shares of common stock issuable upon the exercise of warrants outstanding at $39.75 per share;
55,724 shares of common stock issuable upon the exercise of warrants dated outstanding at $36.60 per share;
47,940 shares of common stock issuable upon the exercise of warrants dated outstanding at $198.00 per share;
133,708 shares of common stock issuable upon the exercise of warrants outstanding at $198.00 per share; and
25,593 shares of common stock issuable upon the exercise of warrants outstanding at $180.00 per share.

If the shares described above that are reserved for issuance to the holders of our options and under our 2017 Plan are issued, or we otherwise issue additional shares of common stock in the future, there could be further dilution to investors participating in this offering. In addition, we anticipate needing to raise additional capital before generating positive cash flows and we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

Therefore, we may not sell the entire amount of securities being offered. The terms of this offering are subject to market conditions and negotiations between us, the placement agent and prospective investors.

Overview

We are a pre-revenue medical device company focused on the design, development and commercialization of innovative insulin pumps using modernized technology to increase pump adoption in the diabetes marketplace. Through the creation of a novel two-part patch pump, our initial product, the MODD1, and its successor tubeless product, the Pivot, we seek to fundamentally alter the trade-offs between cost and complexity and access to the higher standards of care that presently available insulin pumps provide. By simplifying and streamlining the user experience from introduction, prescription, reimbursement, training and day-to-day use, we seek to expand the wearable insulin delivery device market beyond the highly motivated "super users" and expand the category into the mass market. The product seeks to serve both the type 1 and the rapidly growing, especially in terms of device adoption, type 2 diabetes markets. In January 2024, we submitted a 510(k) premarket notification to the United States Food and Drug Administration (the "FDA") for our MODD1 insulin pump, and, in September 2024, we received FDA clearance to market and sell our MODD1 pump in the United States. We are actively working to commercialize our MODD1 product and commence initial shipments in the first half of fiscal 2026, obtain regulatory clearance to market and sell our MODD1 product in foreign jurisdictions, improve the manufacturability and usability of our MODD1 product and submit the Pivot tubeless version of the product for FDA approval during the quarter ending September 30, 2025.

Differentiation

We believe that there are a number of shortcomings and issues with currently available insulin pumps that prevent a substantial number of people who require insulin on a daily basis from choosing an insulin pump to treat their diabetes. We believe, that by tailoring our insulin pump to address such factors, we can expand the scope and adoption rate of insulin pump usage. We believe that to achieve broader market acceptance, an insulin pump must be easier to learn to use, be less time- consuming to operate, more intuitive to both patients and physicians, and meet the standards for coverage by insurance providers so that co-payments required from patients are affordable and the hurdles to insurance coverage are significantly reduced, all while not compromising accuracy and the basal bolus ability of a true pump.

Among the more prominent issues are:

Complexity: Many existing pumps are highly complex and require significant technical expertise to use effectively. We believe such pumps were designed for "super users," who have high levels of motivation and technical competence. The complexity of pumps may be daunting to less technically inclined, less motivated users.
Cumbersome: We believe that a majority of existing pumps are bulky and difficult to manage, requiring a means of carrying the pump around and up to 48 inches of tubing to the injection site to connect the catheter to a pump. The tubing and the cartridge, which holds the insulin, must be replaced every few days. This requires users to carry spare parts and other equipment adding to the difficulty of using the pump. In comparison, our product only requires a cartridge change every few days.

1

Cost: Costs associated with insulin pump therapy can be high and prohibitive, especially for those on fixed or limited incomes. These costs vary by pump and insurance coverage, but multi-thousand-dollar upfront payments, often with substantial co-payments in addition to possible additional co-payments on consumables, can easily place current pumps out of reach for patients. The leading patch pump on the market today also requires the user to discard all the electronics required for pumping and communication every three days, creating a higher cost architecture. This leads to limited or absent reimbursement/coverage and potentially high financial hurdles for patients to gain access.
Outdated style: Consumer electronics devices have evolved in both form and function. Diabetes pumps have not experienced similar progress. We believe that consumers will be more receptive of products designed with the user experience in mind and that many have low tolerance for complex, difficult procedures for use and maintenance of products.
Pump mechanism limitations: Traditional pumps generally utilize a syringe and plunger mechanism to deliver insulin. We believe this design limits the ability to reduce the size of the pump, and also potentially exposes the user to the unintended delivery of the full volume of insulin within the pump, which can cause hypoglycemia or death. We believe that the fear of adverse health events due to technical malfunctions related to traditional pump mechanism limitations deters the adoption of insulin pump therapy.

Our team has substantial knowledge of the diabetes industry and experience in developing, obtaining marketing authorization for, and bringing insulin pumps to market. Based on this experience, we believe that our innovative insulin pump, using a new and proprietary method of pumping insulin, can address most or all of these shortcomings. It provides a state-of-the-art insulin pump capable of both basal (steady flow) and bolus (mealtime dosing) insulin disbursement. It also has been designed considering a natural migration path to multi-chamber/multi-liquid pumps, potentially offering an exciting array of new therapies to patients with diabetes and other conditions.

Our goal is to become the leader in expanding access to insulin pump technology to a wider portion of diabetes sufferers and provide not just care for the super users, but "diabetes care for the rest of us." While our initial target market is people with Type 1 diabetes, we believe there is a substantial opportunity to penetrate the type 2 marketplace, first through our initial MODD1 pump, and with the future introduction of Pivot making our pump the only 3 milliliter, tubeless removable patch pump on the market.

The MODD1, and its successor product the Pivot, are high-precision pumps that we believe represent the best choice for new pump patients because the products will be easy to afford, easy to learn, easy to use, and have a revolutionary design and technology that enable precision with low-cost manufacture and high reproducibility.

Key features include:

Two parts - one reusable, one disposable - snap together to form the working system;
One button interface, easy to learn and use;
90-day reusable, 3-day disposable;
Disposable portion removable at any time from an adhesive-backed retainer, which remains in place;
No external controller required, no charging, no battery replacement; and
Slim profile, lighter weight.

A proprietary survey of American healthcare payors representing 50 million covered lives (approximately 1/3 of U.S. covered lives) performed for us by industry leading survey firm ISA in 2019 has demonstrated that payors are willing to grant equivalent or preferential coverage for a product with this feature set at launch in exchange for discounts of approximately 20%.

Our research, along with marketplace data provided by Seagrove Partners in 2023, estimates that 33% of Americans with Type 1 diabetes, or T1D, have an insulin pump and 28% of Americans with T1D (44% of those who currently utilize MDI) can be classified as having an interest in pump adoption and meeting the American Diabetes Association guidelines of glucose control if their objections to the currently available suite of products can be overcome. They do not want to closely manage their glucose levels and incur the associated time and effort involved. They are the Almost Pumpers. We have developed what we believe to be the most technologically advanced delivery system to overcome the objections and provide the needed motivation for this market to develop. We believe that there are four addressable hurdles to adoption:

Usability: the device needs to be easy to learn and to operate;
Affordability: we will focus on overcoming copay and insurance hurdles rather than leaving the "insurance journey" to the clinician and patient;
Accessibility and Education: we will seek to engage patients to sample this new technology by supplying clinicians with free samples and simple training to allow people to see first-hand the typical barriers to adoption that have been overcome; and
Service and Support: where we will answer their questions and concerns during this diabetes experience.

We believe this conversion process, engaging people to try and thereby receive the benefits of our technology will substantially increase adoption of insulin pumps among both those with T1D and Type 2 diabetes who remain reliant upon multiple daily injections. Diabetes is a disease that appears throughout the world. Therefore, we cannot segment the market by socioeconomics, education or level of care. We intend to create an insulin pump that appeals to all Almost Pumpers.

Our Insulin Pump

Instead of building complex, bespoke, and difficult to manufacture and maintain pumping and control systems, we began with the technology and the user in mind. Using proprietary and patented methods of insulin measurement, we were able to eschew complex mechanisms and instead built a product candidate using only parts from high volume consumer electronics manufacturing lines, breaking the cost vs functionality curve that has existed in the insulin pump space and representing the first truly modern insulin pump design. This is a new kind of product for a new kind of patient.

A good part of our focus has shifted to managing the process of preparing to move our initial production line to our manufacturing partner, Phillips-Medisize, a large tier-one medical device manufacturer, which will manage and operate our production to produce products for human use. We believe that Phillips-Medisize will be able to rapidly scale to higher volumes at lower cost. We continue to devote substantial time and resources, including exhibiting at major diabetes conferences, to better understand the needs and preferences of Almost Pumpers and the specific patient/provider/payor requirements to motivate change from MDI therapy. By making the bolus delivery at meals simple, we believe we will drive improved health outcomes.

MODD1 has several distinguishing features:

1. The pump has a simple button to press to deliver insulin as the patient requires it. The electronic pump uses a simple motor and rotating cam to motivate the insulin into the patient along with a low power Bluetooth and near-field communication (NFC) chips to optionally allow the patient to communicate with their smart phone, tablet, or other mobile computing platform.
2. The pump snaps together with a three-day disposable cartridge that is patient filled with insulin for delivery. It includes the power source and a simple coin cell that allows it to run through the 80-hour life of the cartridge.
3. The infusion set contains a soft 6 mm cannula and an introducer for insertion into the skin and removal of the needle used to transfer insulin to the body.

The system will deliver a small continuous rate called a basal that will provide approximately 50% of the total daily dose required and the user will use the on-pump button to administer boluses, typically before and after meals.

The objective is to make the product candidate simple to acquire and take home, simple to learn and most importantly, simple to use to expand the pump market, drive adoption and ultimately better clinical outcomes.

We have developed a successor product, the Pivot, which represents a new and improved version of the MODD1 and eliminates the external infusion set and incorporates it into the adhesive plate, while maintaining the removable aspect of the pump. We anticipate that we will submit this product for FDA approval in the fall of 2025.

Commercialization Strategy

We plan to commercialize our MODD1 product line using a highly differentiated go-to-market strategy. Generally, current pumps are marketed by a large, direct sales force to end users directly, and the manufacturer provides all training and support, as the current training reimbursement offered by insurance providers is inadequate to motivate clinicians to provide such training to patients. We intend to employ a different strategy and utilize i) distributors to target the daily insulin users who are still managed by a primary care physician and ii) a small direct sales force to directly engage with diabetes educator practices. Specifically, our direct sales force will engage with larger diabetes educator practices, which currently prescribe a high volume of pumps and deliver a consultative message focused on those users that indicate a desire to use a pump but have rejected all of the currently available options. We engaged Seagrove Partners, LLC to conduct a survey of physicians and diabetes educators, and the resulting data suggested that approximately 25% of multiple daily injectors could be receptive to our offering. We believe that the modest 30-minute training requirement for our product, combined with the more limited feature set for our MODD1, will incentivize nurse practitioners to identify and train new users who have not been offered pumps before. This would also allow us to offer virtual or second level training support and not require us to be the primary training provider.

We plan to launch our MODD1 product during the quarter ending September 30, 2025 in a single region in the United States with a select group of providers to gain user experience. During the quarter ending December 31, 2025, we plan to submit a 510(k) premarket notification to the FDA for a new and improved version of the MODD1 product, our Pivot product, which will use our proprietary, integrated insulin-delivery set manufactured by us. We believe the new integrated insulin-delivery set will offer improved user experience, while reducing our production costs. The Pivot pump is the version that we plan to launch nationally in the United States after we receive FDA clearance, which we expect could occur during the quarter ending March 31, 2026.

We have also begun the process of obtaining Conformite Europeenne, or CE, mark clearance for our Pivot pump, which would allow us to market and sell in European markets. We expect to obtain CE mark clearance during the quarter ending March 31, 2026. Our initial strategy to address European markets is to partner with distributors to bring the Pivot to market in those countries that accept the CE mark and have acceptable reimbursement. We believe that the combination of our patch pump form factor, lower cost at scale and lower training burden is well suited for European markets where there are very few physicians or nurses available to provide training. This would allow the Pivot to gain rapid adoption in areas where pump penetration is currently much lower than in the United States. We will target other select international markets using the same approach.

We believe the combination of these differentiated approaches will enable us to take reasonable initial market share, while not incurring the significant overhead cost of existing commercialization strategies employed by the incumbents, where competition for users is intense.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplements, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future debt securities we may offer pursuant to this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. If we so indicate in a prospectus supplement, the terms of any debt securities offered under such prospectus supplement may differ from the terms we describe below, and to the extent the terms set forth in a prospectus supplement differ from the terms described below, the terms set forth in the prospectus supplement shall control.

We may sell from time to time, in one or more offerings under this prospectus, debt securities, which may be senior or subordinated. We will issue any such senior debt securities under a senior indenture that we will enter into with a trustee to be named in the senior indenture. We will issue any such subordinated debt securities under a subordinated indenture, which we will enter into with a trustee to be named in the subordinated indenture. We use the term "indentures" to refer to either the senior indenture or the subordinated indenture, as applicable. The indentures will be qualified under the Trust Indenture Act of 1939, as in effect on the date of the indenture. We use the term "debenture trustee" to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities.

General

Each indenture will provide that debt securities may be issued from time to time in one or more series and may be denominated and payable in foreign currencies or units based on or relating to foreign currencies. Neither indenture will limit the amount of debt securities that may be issued thereunder, and each indenture will provide that the specific terms of any series of debt securities shall be set forth in, or determined pursuant to, an authorizing resolution and/or a supplemental indenture, if any, relating to such series.

We will describe in each prospectus supplement the following terms relating to a series of debt securities:

the title or designation;
the aggregate principal amount and any limit on the amount that may be issued;
the currency or units based on or relating to currencies in which debt securities of such series are denominated and the currency or units in which principal or interest or both will or may be payable;
whether we will issue the series of debt securities in global form, the terms of any global securities and who the depositary will be;
the maturity date and the date or dates on which principal will be payable;
the interest rate, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the date or dates interest will be payable and the record dates for interest payment dates or the method for determining such dates;
whether or not the debt securities will be secured or unsecured, and the terms of any secured debt;
the terms of the subordination of any series of subordinated debt;
the place or places where payments will be payable;
our right, if any, to defer payment of interest and the maximum length of any such deferral period;
the date, if any, after which, and the price at which, we may, at our option, redeem the series of debt securities pursuant to any optional redemption provisions;
the date, if any, on which, and the price at which we are obligated, pursuant to any mandatory sinking fund provisions or otherwise, to redeem, or at the holder's option to purchase, the series of debt securities;
whether the indenture will restrict our ability to pay dividends, or will require us to maintain any asset ratios or reserves

11

whether we will be restricted from incurring any additional indebtedness;
a discussion on any material or special U.S. federal income tax considerations applicable to a series of debt securities;
the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof; and
any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities.

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

Conversion or Exchange Rights

We will set forth in the prospectus supplement the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Information Concerning the Debenture Trustee

The debenture trustee, other than during the occurrence and continuance of an event of default under the applicable indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the debenture trustee under such indenture must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the debenture trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check which we will mail to the holder. Unless we otherwise indicate in a prospectus supplement, we will designate the corporate trust office of the debenture trustee in the City of New York as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the debenture trustee for the payment of the principal of or any premium or interest on any debt securities which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

Subordination of Subordinated Debt Securities

Our obligations pursuant to any subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of senior indebtedness we may incur. It also does not limit us from issuing any other secured or unsecured debt.

12

DESCRIPTION OF WARRANTS

We may offer, sell and issue, from time to time, warrants to purchase shares of our common stock. The warrants may be issued independently or together with shares of our common stock and may be attached to or separate from the shares of our common stock. If we issue warrants, they will be evidenced by warrant agreements or warrant certificates issued under one or more warrant agreements, which will be contracts between us and/or a bank or trust company, as warrant agent, and the holders of the warrants or an agent for the holders of the warrants, all as shall be set forth in the prospectus supplement relating to warrants being offered pursuant to such prospectus supplement. The forms of warrant agreements or warrant certificates, as applicable, relating to the warrants will be filed as exhibits to the registration statement of which this prospectus is part and/or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the warrants and warrant agreements are subject to, and qualified in their entirety by reference to, all of the provisions of the warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants.

Whenever warrants are to be issued and sold pursuant to this prospectus, we will file a prospectus supplement relating to that offer and sale which will specify (in each case as applicable):

the number of shares of common stock purchasable upon exercise of the warrants and the exercise price at which such number of shares may be purchased upon exercise;
the price or prices at which the warrants will be issued;
the provisions, if any, for changes to or adjustments in the exercise price;
the provisions, if any, for call rights or put rights relating to the warrants or the underlying shares of common stock;
the date on which the right to exercise the warrants shall commence and the date on which the right will expire;
if applicable, the number of warrants issued with each share of our common stock;
if applicable, the date on and after which the warrants and the related common stock will be separately transferable; and
any other terms of the warrants, including terms, procedures and limitations relating to the exchange, exercise and settlement of the warrants.

Until any warrants to purchase common stock are exercised, the holders of warrants will not be entitled, by virtue of being such holders, to vote, consent, receive dividends, receive notice as stockholders with respect to any meeting of stockholders for the election of our directors or any other matter, or to exercise any rights whatsoever as our stockholders.

Each warrant will entitle the holder to purchase for cash such shares of our common stock at such exercise price as shall be in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the warrants offered thereby. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the prospectus supplement relating to the warrants offered thereby. After the close of business on the expiration date, unexercised warrants will become void.

The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Upon receipt of payment and the warrant certificate properly completed and duly executed at the Company or the corporate trust office of the warrant agent, as applicable, or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of our common stock purchasable upon such exercise. If less than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

13

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus in any combination from time to time. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. If we issue units, they will be evidenced by unit agreements or unit certificates issued under one or more unit agreements, which will be contracts between us and the holders of the units or an agent for the holders of the units. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date. The forms of unit agreements or unit certificates, as applicable, relating to the units will be filed as exhibits to the registration statement that includes this prospectus, or as an exhibit to a filing with the SEC that is incorporated by reference into this prospectus.

14

In addition, the terms of the transaction, including commissions, discounts and any other compensation of the underwriters and dealers, if any, will be set forth in the applicable prospectus supplement, which prospectus supplement will be used by the underwriters to make resales of the offered securities. If underwriters are utilized in the sale of the offered securities, the offered securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

transactions on the Nasdaq Capital Market or any other organized market where the securities may be traded;
in the over-the-counter market;
in negotiated transactions; or
under delayed delivery contracts or other contractual commitments.

We may grant to the underwriters options to purchase additional offered securities to cover over-allotments, if any, at the public offering price with additional underwriting discounts or commissions, as may be set forth in the applicable prospectus supplement. If we grant any over-allotment option, the terms of the over-allotment option will be set forth in the applicable prospectus supplement.

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

We may indemnify agents, underwriters and dealers against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. Agents, underwriters or dealers, or their respective affiliates, may be customers of, engage in transactions with or perform services for us or our respective affiliates, in the ordinary course of business.

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is traded on the Nasdaq Capital Market. We may elect to list any other class or series of securities on any exchange and, in the case of our common stock, on any additional exchange. However, unless otherwise specified in the applicable prospectus supplement, we will not be obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the offered securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

To comply with the securities laws of certain states, if applicable, the securities offered by this prospectus will be offered and sold in those states only through registered or licensed brokers or dealers.

In compliance with guidelines of the Financial Industry Regulatory Authority, or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.
