EXPLANATORY NOTE

This Post-Effective Amendment No. 1 (this “ Amendment ”)
to the Registration Statement on Form S-1, as amended (SEC File No. 333-293093) (the “ Original Registration Statement ”),
of SunPower Inc. (the “Company”) is being filed pursuant to the undertakings in the Original Registration Statement to update
and supplement the information contained in the Original Registration Statement, which was originally declared effective by the Securities
and Exchange Commission on February 10, 2026.

The Original Registration Statement, as amended by this Amendment,
pertains solely to the registration of up to 22,381,878 shares of our common stock, par value $0.0001 per share (the “ common
stock ”), consisting of (i) up to 22,206,878 shares of common stock that may be issued to YA II PN, LTD (“ Yorkville ”)
pursuant to convertible promissory notes that have been or may be issued by us to Yorkville pursuant to a standby equity purchase agreement
(the “ SEPA ”), dated as of January 27, 2026, by and between us and Yorkville (the “ Conversion Shares ”)
and (ii) 175,000 shares of common stock we issued to Yorkville as consideration for its commitment to purchase shares of our common stock
pursuant to the SEPA (the “ Commitment Shares ” and, collectively with the Conversion Shares, the “ Offered Securities ”).
The Offered Securities were initially registered on the Original Registration Statement.

For the convenience of the reader, this Amendment
sets forth the Original Registration Statement in its entirety, as amended by this Amendment. This Amendment is being filed to incorporate
certain information from the Company’s Annual Report on Form 10-K for the year ended December 28, 2025, filed with the SEC on April
14, 2026, and the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended March 28, 2026, filed with the SEC on May

No additional securities are being registered under this Post-Effective
Amendment No. 1. All applicable registration fees were previously paid.

The information in
this preliminary prospectus is not complete and may be changed. The securities described herein may not be sold until the registration
statement filed with the U.S. Securities and Exchange Commission is declared effective. This preliminary prospectus is not an offer to
sell these securities and it is not soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

PRELIMINARY PROSPECTUS

SUBJECT TO COMPLETION,
DATED MAY 22, 2026

SUNPOWER INC.

Up to 22,381,878 Shares of Common Stock

This prospectus relates to the registration of
the resale or other disposition of up to 22,381,878 shares of our common stock by YA II PN, LTD (“ Yorkville ”). Yorkville
is also referred to in this prospectus as the Selling Securityholder. The shares of our common stock to which this prospectus relates
have been or may be issued by us to Yorkville pursuant to a standby equity purchase agreement, dated as of January 27, 2026, by and between
us and Yorkville (the “ SEPA ”). Such shares of common stock include (i) up to 22,206,878 shares of common stock that
may be issued to Yorkville pursuant to a convertible promissory note issued by us to Yorkville pursuant to the SEPA (the “ Conversion
Shares ”) and (ii) 175,000 shares of common stock we issued to Yorkville as consideration for its commitment to purchase shares
of our common stock pursuant to the SEPA (the “ Commitment Shares ” and, collectively with the Conversion Shares, the
“ Offered Securities ”).

We are not selling any securities under this prospectus
and will not receive any of the proceeds from the sale of our common stock by the Selling Securityholder. Prior to the date of this prospectus,
we received (i) proceeds of $1,710,000 in connection with our sale and issuance to Yorkville on January 27, 2026 of a convertible promissory
note in the aggregate principal amount of $1,900,000 as a pre-paid advance under the SEPA and (ii) proceeds of $9,000,000 from the issuance
and sale by us to Yorkville of the YA Debenture; and we may receive proceeds from sales of common stock that we may elect to make to Yorkville
pursuant to the SEPA, if any, from time to time after the date of this prospectus. The net proceeds from sales, if any, under the SEPA,
will depend on the frequency and prices at which we sell shares of common stock to Yorkville after the date of this prospectus. See “PROSPECTUS
SUMMARY - The Standby Equity Purchase Agreement” on page 4 of this prospectus for a description of the SEPA and “SELLING
SECURITYHOLDER” on page 99 of this prospectus for additional information regarding the Selling Securityholder.

The Selling Securityholder may sell or otherwise
dispose of the common stock described in this prospectus in a number of different ways and at varying prices. Yorkville is an “underwriter”
within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended (the “ Securities Act ”), only with
respect to advances under the SEPA (“ Advances ”) and any profits on the sales of shares of our common stock by Yorkville
acquired under the SEPA and any discounts, commissions, or concessions received by Yorkville are deemed to be underwriting discounts and
commissions under the Securities Act. If any underwriters, dealers, or agents are involved in the sale of any of the securities, their
names and any applicable purchase price, fee, commission, or discount arrangement between or among them will be set forth, or will be
calculable from the information set forth, in any applicable prospectus supplement. Yorkville is not an “underwriter” within
the meaning of Section 2(a)(11) of the Securities Act with respect to the shares of our common stock issuable upon conversion by Yorkville
of the convertible promissory notes issued to Yorkville pursuant to the SEPA. We will pay the expenses incurred in registering under the
Securities Act the offer and sale of the shares of the common stock to which this prospectus relates by the Selling Securityholder, including
our legal and accounting fees. See “Plan of Distribution” on page 114 of this prospectus for more information. No securities
may be sold without delivery of this prospectus and any applicable prospectus supplement describing the method and terms of the offering
of such securities. You should carefully read this prospectus and any applicable prospectus supplement before you invest in our securities.

We engaged Northland Capital Markets (“ Northland ”)
as our placement agent in connection with the SEPA. We have agreed to pay Northland a cash fee of 5.0% based upon the aggregate gross
proceeds received from the sales of convertible promissory notes and common stock that we elect to make to Yorkville pursuant to the
SEPA. See “Plan of Distribution” on page 114 of this prospectus for additional information regarding this arrangement.

Shares of our common stock are listed on the Nasdaq
Global Market (“ Nasdaq ”) under the symbol “SPWR”. On May 15, 2026, the closing price of our common stock
was $1.02.

We are an “emerging growth company”
as defined under U.S. federal securities laws and, as such, have elected to comply with reduced public company reporting requirements.
This prospectus complies with the requirements that apply to an issuer that is an emerging growth company.

Investing in our securities involves a high
degree of risk. You should review carefully the risks and uncertainties described in the section titled “Risk Factors” beginning
on page 11 of this prospectus, and under similar headings in any amendments or supplements to this prospectus.

Neither the Securities and Exchange Commission
nor any state securities commission has approved or disapproved of these securities, or passed upon the accuracy or adequacy of this prospectus.
Any representation to the contrary is a criminal offense.

The forward-looking statements
contained in this prospectus are based on our current expectations and beliefs concerning future developments and their potential effects
on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements
involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or
performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties
include, but are not limited to, those described in the section titled “Risk Factors” and elsewhere in this prospectus. Should
one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in
material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise, except as required by law. We discuss in greater detail
many of these risks under the section titled “Risk Factors” contained in the applicable prospectus supplement, in any free
writing prospectuses we may authorize for use in connection with a specific offering, and in our most recent Annual Report on Form 10-K
and in our most recent Quarterly Report on Form 10-Q. Also, these forward-looking statements represent our estimates and assumptions only
as of the date of the document containing the applicable statement. Unless required by law, we undertake no obligation to update or revise
any forward-looking statements to reflect new information or future events or developments. You should read this prospectus, any applicable
prospectus supplement, together with the documents we have filed with the SEC and any free writing prospectus that we may authorize for
use in connection with a specific offering completely and with the understanding that our actual future results may be materially different
from what we expect. We qualify all of the forward-looking statements in the foregoing documents by these cautionary statements.

In addition, statements that
“we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon
information available to us as of the date of this prospectus, and while we believe such information forms a reasonable basis for such
statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an
exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you
are cautioned not to unduly rely upon these statements.

Prospectus
Summary

This summary highlights
information contained elsewhere in this prospectus and does not contain all of the information that you should consider in making your
investment decision. Before investing in our securities, you should carefully read this entire prospectus, including our financial statements
and related notes appearing at the end of this prospectus and the information set forth in the sections titled “Risk Factors”
and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Unless the context otherwise
requires, we use the terms “SunPower,” “company,” “we,” “us” and “our” in
this prospectus to refer to SunPower Inc. and our wholly owned subsidiaries.

Our Mission

Our mission is to deliver
energy-efficient solutions to homeowners and small to medium-sized businesses that allow them to lower their energy bills while reducing
their carbon footprint. SunPower Inc. or SunPower, has created a unique, end-to-end offering that delivers a best-in-class customer experience
with a robust technology platform, financing solutions, and high-performance solar equipment.

Business Overview

SunPower Inc. (the “Company”)
is the rebranded name of Complete Solaria, Inc. The rebranding was effective April 22, 2025 and became legally effective on October 17,
2025. We are headquartered in Orem, Utah.

Complete Solaria, Inc. (“Complete
Solaria”) was formed in November 2022 through the merger of Complete Solar Holding Corporation, a Delaware corporation (“Complete
Solar”), and The Solaria Corporation, a Delaware corporation (such entity, “Solaria,” and such transaction, the “Business
Combination”). Complete Solaria created a technology platform to offer clean energy products to homeowners by enabling a national
network of sales partners and build partners. Our sales partners generate solar installation contracts with homeowners on our behalf.
To facilitate this process, we provide the software tools, sales support and brand identity to our sales partners, making them competitive
with national providers. We fulfill our customer contracts by engaging with local construction specialists and using our in-house installation
experts. We manage the customer experience and complete all pre-construction activities prior to delivering build-ready projects including
hardware, engineering plans, and building permits to our builder partners and in-house teams.

In October 2023, we sold the
solar panel assets of The Solaria Corporation, including intellectual property and customer contracts to Maxeon Solar Technologies, Ltd.
(“Maxeon”) pursuant to the terms of an asset purchase agreement (the “Disposal Agreement”). Under the terms of
the Disposal Agreement, Maxeon agreed to acquire certain assets and employees of Complete Solaria for an aggregate purchase price of approximately
$11.0 million consisting of 1,100,000 shares of Maxeon ordinary shares.

We expect to continue making
acquisitions and entering into strategic partnerships as part of our long-term business strategy. For example, on September 24, 2025,
we completed the purchase of all the membership interests of Sunder Energy, LLC (“Sunder”). Sunder provides a third-party
solar energy sales force to initiate and execute contracts with customers throughout the United States. Sunder’s sales force works
with solar installation companies in which Sunder acts as the agent for each transaction entered. Sunder earns revenue based on residential
solar installation contracts for residential homeowners that are sold to installation companies in accordance with its contracts with
those installation companies. Upon entering into a sales contract, the requisite performance obligation of Sunder is to assist the installation
companies in the progress of the installation and obtain permission to operate. On November 21, 2025, we completed the purchase of all
the membership interest of Ambia Energy, LLC (“Ambia”). Ambia is a residential solar energy system installer which operates
in various markets throughout the United States. Ambia generates revenue from selling and installing solar energy systems or orchestrating
the sale of a solar energy system which will be installed by a third party. On January 30, 2026, we completed the purchase of all of the
equity interests of Cobalt Power Systems, Inc. (“Cobalt”). Cobalt is an installer of residential and commercial solar energy
systems in the San Francisco Bay area. Cobalt generates revenue from the design and installation of solar power systems.

On August 5, 2024, we entered
into an Asset Purchase Agreement (the “APA”) among us and SunPower Corporation and its direct and indirect subsidiaries (collectively,
the “SunPower Debtors”) providing for the sale and purchase of certain assets relating to the Blue Raven Solar business, New
Homes Business and Non-Installing Dealer network previously operated by the SunPower Debtors (the “Acquired SunPower Assets”).
The APA was entered into in connection with a voluntary petition filed by SunPower under Chapter 11 of the United States Code, 11 U.S.C.§§
101-1532. The sale was approved on September 23, 2024, by the United States Bankruptcy Court for the District of Delaware. We completed
the acquisition of the Acquired SunPower Assets effective September 30, 2024. The assets and businesses acquired by us under the APA are
referred to as the “SunPower Businesses.” As part of the acquisition the Company acquired Albatross, an order-to-management
proprietary software to manage our orders, fulfillment and customer service all in one central location.

The acquisitions of Sunder,
Ambia, Cobalt and SunPower Businesses are collectively referred to herein as “Acquisitions”.

Revenue Model

We offer solar system sales
and installation to residential homeowners and the new home builders’ communities. The Acquisitions will allow us to accelerate
our revenue growth and expand our footprint to deliver solar system sales into regions where we might have not previously done business.

We sell solar systems to homeowners,
home builders and small to medium-sized commercial customers through third-party sales partners. As a result of our acquisition of Sunder,
we operate a solar energy sales force to initiate and execute contracts with customers throughout the United States. We manage every aspect
of project management for those contracts before ultimately contracting with builder partners or using in-house installation experts to
complete the construction and installation of the solar systems. This residential solar platform provides homeowners with simple pricing
for solar energy that provides significant savings compared to traditional utility energy. Homeowners can choose from a wide array of
system features and financing options that best meet their needs. By delivering the best-matched products and a best-in-class customer
experience, we establish valuable customer relationships that can extend beyond the initial solar energy system purchase and provide us
with opportunities to offer additional products and services in the future.

Technology Innovation

Since inception, we have continued
to invest in a platform of services and tools to enable large-scale operations for sales and builder partners. The platform incorporates
processes and software solutions that simplify and streamline design, proposals, and project management throughout the lifecycle of a
residential solar project. The platform empowers new market entrants and smaller industry participants with its plug-and-play capabilities.
The ecosystem we have built provides broad reach, and we believe it positions us for sustained and rapid growth through a capital-efficient
business model. The network of our partners continues to expand today.

We use salesforce.com to manage
and fulfill orders which replaced our use of Albatross, the rights to which we acquired in connection with our acquisition of the SunPower
Businesses. Albatross is a sales order platform which will be sunset later in 2026. Our acquisition of Sunder included Merdeka, a software
platform which gives access from bookings to energization. We currently have this platform on view only and believe it has future potential
as a differentiating option compared to our competition.

Differentiation and Operating Results

Delivering a differentiated
customer experience is core to our strategy. It emphasizes a customized solution, including a design specific to each customer’s
home and pricing configurations that typically drive both customer savings and value. Developing a trusted brand and providing a customized
solar service offering resonates with customers accustomed to a traditional residential power market that is often overpriced and lacking
in customer choice.

Our overall mission is to
deliver energy-efficient solutions to homeowners, home builders and small to medium-sized businesses that allow them to lower their energy
bills while reducing their carbon footprint. We want to pass our operational costs savings back to our customers by keeping costs low
in an environment where labor costs are rising and interest rates remain uncertain. These operational costs savings are attributed to
the workforce that was acquired as part of the SunPower Acquisition. We expanded our operations center that supports operations, order
process, customer care and support, credit and collections, procurement, vendor management and accounting related functions, and have
rationalized our headcount.

Corporate Information

We were originally known as
Freedom Acquisition I Corp (“FACT”). We are engaged in solar system sales and associated commerce. On July 18, 2023, Complete
Solaria, FACT, and certain other entities consummated the transactions contemplated under that certain amended and restated Business Combination
Agreement, dated as of May 26, 2023, following the approval at the special meeting of the stockholders of FACT held July 11, 2023. In
connection with the closing of the Business Combination, we changed our name from Freedom Acquisition I Corp. to Complete Solaria, Inc.

Recent Developments

10.0% Notes Offering and Related Transactions

On April 23, 2026, we
closed our private offering (the “ Offering ”) of $41,000,000 aggregate principal amount of our 10.0% Notes (as defined
below), consisting of: (i) the sale and issuance of $24,000,000 aggregate principal amount of 10.0% Notes to qualified institutional
buyers; (ii) the sale and issuance of $1,000,000 principal amount of 10.0% Notes to an institutional accredited investor; (iii) the issuance
of $6,000,000 principal amount of 10.0% Notes to entities affiliated with Thurman John “T.J.” Rodgers, the Company’s
Chief Executive Officer and Chairman, in consideration for $6,000,000 previously funded to the Company pursuant to simple agreements
for future equity; and (iv) the issuance of $10,000,000 aggregate principal amount of 10.0% Notes in connection with the exchange of
the promissory note originally issued by the Company to Chicken Parm Pizza LLC (“ CPP ”) on September 24, 2025 in connection
with the Company’s acquisition of Sunder Energy (the “ Seller Note ”). On May 20, 2026, the Company issued and
sold a further $5,000,000 aggregate principal amount of 10.0% Notes in a private offering to an additional purchaser.

On April 21, 2026, in connection
with the Offering, the Company and Yorkville entered into a letter agreement (the “ YA Letter ”). Pursuant to the YA
Letter, the Company agreed to voluntary prepay $5,000,000 of the outstanding principal amount of YA Debenture (as defined below), resulting
in a revised outstanding principal balance under the YA Debenture of $5,000,000. The Company further agreed to repay the remaining principal
balance and accrued interest under the YA Debenture in four equal monthly installments of $1,287,000, with the first payment due on May
5, 2026. Pursuant to the YA Letter, Yorkville further consented to the issuance of the Notes and the grant of the liens pursuant to the
Security Agreement (as defined below).

In connection with the closing
of the Offering, on April 23, 2026, the Company executed and delivered the Indenture relating to the Notes (the “ Indenture ”)
among the Company, the guarantor named therein, and U.S. Bank Trust Company, National Association, as trustee (in such capacity, the “ Trustee ”)
and as collateral agent (in such capacity, the “ Collateral Agent ”). Additionally, on April 23, 2026, the Company and
the Collateral Agent entered into the Pledge and Security Agreement (the “ Security Agreement ”). Pursuant to the Security
Agreement, the 10.0% Notes are secured by a first-priority security interest in substantially all of the assets of the Company and any
Guarantor, subject to certain exceptions and permitted liens. Pursuant to the Security Agreement, on April 23, 2026, the Company and the
Collateral Agent entered into a separate Patent Security Agreement (the “ Patent Security Agreement ”) and Trademark
Security Agreement (the “ Trademark Security Agreement ”) in connection with the grant of the first-priority security
interest under the Security Agreement.

Pursuant to the Note Purchase
Agreement entered into between the Company and CPP on April 21, 2026 (the “ CPP Note Purchase Agreement ”), in connection
with the closing of the Offering, on April 23, 2026: (i) the Company paid $4,000,000 in cash to CPP and (ii) entered into an amended and
restated Seller Note with CPP (the “ A&R Seller Note ”).

Further, on April 23, 2026,
the Company and certain holders of the Company’s 7.0% Notes (as defined below) closed the transactions under the exchange agreements
executed on April 21, 2026 (the “ Exchange Agreements ”). In connection with the closings under the Exchange Agreements,
the Company repurchased $21,250,000 aggregate principal amount of outstanding 7.0% Notes in exchange for (i) the issuance of an aggregate
of 18,805,310 shares of Common Stock and (ii) the payment of approximately $456,438 of accrued interest payable under the exchanged 7.0%
Notes.

Company reduced its inside sales group from 90 to 15 people, and the Company reduced finance function costs. The Company estimates that
the charges related to the reduction in force will approximate $0.3 million, consisting principally of compensation related costs.

Implications of Being a Smaller Reporting Company
and Emerging Growth Company

We are a “smaller reporting
company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure
obligations, including, among other things, providing only two years of audited financial statements and reduced disclosure obligations
regarding executive compensation. We will remain a smaller reporting company until the last day of any fiscal year for so long as either
(1) the market value of our shares of common stock held by non-affiliates does not equal or exceed $250.0 million as of the prior June
30th, or (2) our annual revenues did not equal or exceed $100.0 million during such completed fiscal year and the market value of our
shares of common stock held by non-affiliates did not equal or exceed $700.0 million as of the prior June 30th. To the extent we take
advantage of any reduced disclosure obligations, it may make the comparison of our financial statements with other public companies difficult
or impossible.

We are an “emerging
growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“ JOBS Act ”). As an emerging growth
company, we are exempt from certain requirements related to executive compensation, including the requirements to hold a nonbinding advisory
vote on executive compensation and to provide information relating to the ratio of total compensation of our President and Chief Executive
Officer to the median of the annual total compensation of all of our employees, each as required by the Investor Protection and Securities
Reform Act of 2010, which is part of the Dodd-Frank Act.

Section 102(b)(1) of the
JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private
companies (that is, those that have not had a registration statement under the Securities Act declared effective or do not have a class
of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS
Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging
growth companies, but any such an election to opt out is irrevocable. We have elected to opt out of such extended transition period.

We will remain an emerging
growth company until the earlier of: (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of FACT’s
initial public offering, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be
a large accelerated filer, which means the market value of our common equity that is held by non-affiliates exceeds $700 million as of
the end of the prior fiscal year’s second fiscal quarter; and (2) the date on which we have issued more than $1.00 billion in non-convertible
debt securities during the prior three-year period. References herein to “emerging growth company” are to its meaning under
the Securities Act, as modified by the JOBS Act.

The Standby Equity Purchase Agreement and the
YA Debenture

On January 27, 2026 (the
“ SEPA Effective Date ”), we entered into a Standby Equity Purchase Agreement (the “ SEPA ”) with YA
II PN, LTD., a Cayman Islands exempt limited company (“ Yorkville ”).

Pursuant to the SEPA, we
issued to Yorkville a convertible promissory note in the principal amount of $1.9 million (the “ Promissory Note ”) as
a pre-paid advance (the “ Pre-Paid Advance ”) under the SEPA.

4

Additionally, pursuant to
the SEPA, and upon the satisfaction of the conditions to Yorkville’s purchase obligation set forth therein, including the registration
of shares of common stock issuable pursuant to the SEPA for resale, we will have the right, from time to time, until January 27, 2029,
to require Yorkville to purchase up to an additional $25.0 million of shares of common stock (the “ Commitment Amount ”),
subject to certain limitations and conditions set forth in the SEPA, by delivering written notice to Yorkville (an “ Advance Notice ”).

If there is no balance outstanding
under the Promissory Note, we may, in our sole discretion, select the amount of the Advance that we desire to issue and sell to Yorkville
in each Advance Notice, subject to a maximum limit equal to 100% of the average of the daily volume traded of our common stock on the
Nasdaq for the five consecutive trading days immediately preceding the delivery of an Advance Notice (the “ Maximum Advance Amount ”).
If there is a balance outstanding under the Promissory Note, we may only submit an Advance Notice (i) if an Amortization Event (as defined
in the Promissory Note) has occurred and our obligation to make prepayments under the Promissory Note has not ceased, and (ii) the aggregate
purchase price owed to us from such Advances (the “ Advance Proceeds ”) will be paid by Yorkville by offsetting the amount
of the Advance Proceeds against an equal amount outstanding under the Promissory Note. Pursuant to an Advance Notice, the shares will
be issued and sold to Yorkville at a per share price equal to, at our election as specified in the relevant Advance Notice: (i) 96% of
the Market Price for any period beginning at such time on such date that the Company receives confirmation of receipt of such Advance
Notice by Yorkville and ending on 4:00 p.m. Eastern Time on the date of the applicable Advance Notice, or (ii) 97% of the Market Price
for the three consecutive trading days commencing on the day such Advance Notice is deemed delivered pursuant to the terms of the SEPA.

We paid Yorkville a structuring
and due diligence fee of $50,000 and issued to Yorkville 175,000 shares of common stock (the “ Commitment Shares ”) as
a commitment fee. We have separately registered the Commitment Shares for resale or other disposition pursuant to the Prior Registration
Statement.

On March 6, 2026, we entered
into a separate purchase agreement with Yorkville (the “ YA Debenture Purchase Agreement ”) pursuant to which Yorkville
purchased, and we issued, a convertible debenture in the principal amount of $10.0 million (the “ YA Debenture ”). At
the closing under the YA Debenture Purchase Agreement, we issued the YA Debenture to Yorkville in the original principal amount of $10.0
million for a purchase price of $9.0 million, less certain fees payable under the YA Debenture Purchase Agreement. The YA Debenture accrues
interest on the outstanding principal balance at an annual rate equal to 0%, which will increase to an annual rate of 18% upon the occurrence
of an event of default under the YA Debenture for so long as such event remains uncured. The YA Debenture will mature on March 6, 2027,
which may be extended at the option of Yorkville.

On April 21, 2026, in connection
with the Company’s offering of its 10.0% Notes, we entered into a letter agreement with Yorkville (the “ YA Letter ”).
Pursuant to the YA Letter, we agreed to voluntary prepay $5.0 million of the outstanding principal amount of the YA Debenture, resulting
in a revised outstanding principal balance under the YA Debenture of $5.0 million. We further agreed to repay the remaining principal
balance and accrued interest under the YA Debenture in four equal monthly installments of $1.287 million, with the first payment due on
May 5, 2026. As a result, on each of June 5, 2026, July 5, 2026 and August 5, 2026 (each an “ Installment Date ”), the
Company is required to pay an installment amount under the YA Debenture equal to (i) $1.25 million, plus (ii) a $37,500 payment premium
(collectively, the “ Installment Amount ”). We may repay each applicable Installment Amount, at our option, (a) in cash
on or before the applicable Installment Date or (b) by submitting an advance notice under the SEPA, or a combination of a payment in cash
and delivery of such advance notice. At any time after the effective date, Yorkville may convert any portion of the outstanding balance
under the YA Debenture into shares of our common stock at an adjusted fixed price of $1.64 per share (the “ Fixed Price ”).
Additionally, at any time on or after any Installment Date, Yorkville may convert any portion of any due and unpaid Installment Amount
outstanding under the YA Debenture into shares of our common stock at a price equal to 95% of the volume weighted average price of our
common stock during the five trading days prior to the conversion date (but the conversion price will not be lower than the “Floor
Price” then in effect).

The Company, at our option,
shall have the right to redeem early all or a portion of the amounts outstanding under the YA Debenture upon written notice to Yorkville
(an “ Optional Redemption ”), provided, that we may only deliver a notice of Optional Redemption if the VWAP of our common
stock at the time the notice is delivered is less than the Fixed Price. In connection with an Optional Redemption, the redemption price
payable by us will be equal to (i) the outstanding principal amount of the YA Debenture being redeemed, plus (ii) a payment premium equal
to 3% of the principal amount being repaid, and plus (iii) accrued and unpaid interest under the YA Debenture; however, the prepayment
premium shall not apply to any Optional Redemption of the YA Debenture if the redemption price is paid on or before April 30, 2026.

Under the applicable rules
of The Nasdaq Stock Market LLC (the “ Nasdaq Rules ”), and pursuant to the SEPA and the YA Debenture Purchase Agreement,
in no event may we issue or sell to Yorkville shares of our common stock in excess of 22,381,878 shares (the “ Exchange Cap ”),
which was 19.99% of the shares of our common stock outstanding immediately prior to the Effective Date, unless we obtain stockholder approval
to issue shares of common stock in excess of the Exchange Cap. On March 25, 2026, our stockholders approved the issuance of shares pursuant
to the SEPA and the Promissory Note for the Pre-Paid Advance in excess of the Exchange Cap to Yorkville in accordance with the Nasdaq
Rules. Further stockholder approval is required to issue shares of our common stock in excess of the Exchange Cap with respect to the
YA Debenture. In any event, we may not issue or sell any shares of common stock under the SEPA, the YA Debenture Purchase Agreement or
the YA Debenture if such issuance or sale would breach any applicable Nasdaq Rules.

We may not issue or sell
any shares of common stock to Yorkville under the SEPA, the YA Debenture Purchase Agreement, the Promissory Note or the YA Debenture,
which, when aggregated with all other shares of common stock then beneficially owned by Yorkville and its affiliates (as calculated pursuant
to Section 13(d) of the Securities Exchange Act of 1934, as amended, and Rule 13d-3 promulgated thereunder), would result in Yorkville
and its affiliates beneficially owning more than 4.99% of the then-outstanding shares of our common stock.

The SEPA will automatically
terminate on the earlier to occur of (i) January 27, 2029 or (ii) the date on which Yorkville has purchased from us under the SEPA the
Commitment Amount in full. We may terminate the SEPA at any time upon five trading days’ prior written notice to Yorkville, provided
that there are no outstanding Advance Notices under which we are yet to issue common stock and provided that we have paid all amounts
owed to Yorkville pursuant to the SEPA and the Promissory Note. We and Yorkville may also agree to terminate the SEPA by mutual written
consent. Neither we nor Yorkville may assign or transfer our respective rights and obligations under the SEPA, and no provision of the
SEPA may be modified or waived by us or Yorkville other than by an instrument in writing signed by both parties.

Each of the SEPA and the
YA Debenture Purchase Agreement contains customary representations, warranties, conditions, and indemnification obligations of the parties.
The representations, warranties, and covenants contained in the SEPA and the YA Debenture Purchase Agreement were made only for purposes
of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations
agreed upon by the parties. Copies of the agreements have been filed as exhibits to the registration statement that includes this prospectus
and are available electronically on the SEC’s website at www.sec.gov.

In connection with the SEPA,
on January 27, 2026, we entered into a registration rights agreement (the “ January 2026 YA RRA ”) with Yorkville pursuant
to which we agreed to file a registration statement registering the resale of the common stock underlying the Promissory Note, the Commitment
Shares and additional Advances pursuant to the SEPA. In connection with the issuance of the YA Debenture, on March 6, 2026, we entered
into a further registration rights agreement (the “ March 2026 YA RRA ”) with Yorkville pursuant to which we agreed to
file a registration statement registering the resale of the common stock underlying the YA Debenture.

Other than as stated above,
we will control the timing and amount of any sales of common stock to Yorkville that we may elect, in our sole discretion, to effect from
time to time during the term of the SEPA. Actual sales of shares of common stock to Yorkville under the SEPA will depend on a variety
of factors to be determined by us from time to time, including, among other things, market conditions, the trading price of the common
stock and determinations by us as to the appropriate sources of funding for our business and our operations.

The net proceeds to us from
any sales that we elect to make to Yorkville under the SEPA, if any, will depend on the frequency and prices at which we sell shares of
our common stock to Yorkville. We expect that any proceeds received by us from such sales to Yorkville will be used for general corporate
purposes.

So long as the outstanding
balance owed outstanding under the Promissory Note and the YA Debenture is more than $2.0 million, we will not (a) repay any loans to
any executives or employees of the Company or to make any payments in respect of any related party debt (other than regular interest payments)
or (b) effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of common stock or any security
which entitles the holder to acquire Common Shares (or a combination of units thereof) involving a variable rate transaction, other than
involving a variable rate transaction with Yorkville. Notwithstanding the foregoing: (i) prior to the effectiveness of the registration
statement for the YA Debenture, the Company may use the White Lion Purchase Agreement (as defined below), provided that the total gross
proceeds of shares sold under the White Lion Purchase Agreement shall not exceed $4,000,000 during such period; and (ii) we may use the
White Lion Purchase Agreement at any time if either (x) the aggregate outstanding balance owed under the Promissory Note and the YA Debenture
is less than $2,000,000 (in which case, for the avoidance of doubt, we may use the White Lion Purchase Agreement without limitation so
long as the aggregate outstanding balance owed under the Promissory Note and the YA Debenture is less than $2,000,000); or (y) the aggregate
proceeds received by us from any offer and sale of shares pursuant to the White Lion Purchase Agreement are promptly used to pay the amounts
outstanding under the YA Debenture.

6

We further agreed that, during
such time as the outstanding balance owed under the Promissory Note and the YA Debenture is greater than or equal to $2,000,000, without
the prior written consent of Yorkville, neither we nor any of our subsidiaries shall, directly or indirectly (a) enter into, create, incur,
assume, guarantee or suffer to exist any Indebtedness, other than permitted indebtedness under the YA Debenture Purchase Agreement, or
(ii) enter into, create, incur, assume or suffer to exist any lien on or with respect to any of its property or assets now owned or hereafter
acquired or any interest therein or any income or profits therefrom, other than permitted liens under the YA Debenture Purchase Agreement.
Notwithstanding the foregoing, we may effect an issuance otherwise prohibited by the YA Debenture Purchase Agreement so long as we
promptly apply the net cash proceeds of such issuance to repay in full all amounts then owed under the YA Debenture (including all
outstanding principal, accrued and unpaid interest, fees, premiums, and other amounts payable thereunder).

Yorkville has agreed that
none of Yorkville, its sole member, any of their respective officers, or any entity managed or controlled by Yorkville or its sole member
will engage in or effect, directly or indirectly, for its own account or for the account of any other of such persons or entities, any
short sales of the common stock or hedging transaction that establishes a net short position in the common stock during the term of the
SEPA.

Because the per share purchase
price that Yorkville will pay for the SEPA Shares pursuant to any Advance that we may elect to effect pursuant to the SEPA will be determined
by reference to the VWAP during the applicable period for such Advance on the applicable purchase date for such Advance (the “ Purchase
Date ”), as of the date of this prospectus, we cannot determine the actual purchase price per share that Yorkville will be required
to pay for any SEPA Shares that we may elect to sell to Yorkville under the SEPA from and after the Effective Date and, therefore, we
cannot be certain how many SEPA Shares, in the aggregate, we may issue and sell to Yorkville under the SEPA from and after the Effective
Date.

If we elect to issue and
sell to Yorkville more than the 22,381,878 shares of common stock being registered under the Securities Act for resale by Yorkville under
the registration statement that includes this prospectus, which we have the right, but not the obligation, to do, we must first file with
the SEC one or more additional registration statements to register under the Securities Act for the offer and resale by Yorkville of any
such additional shares of our common stock we wish to sell from time to time under the SEPA, which the SEC must declare effective, before
we may elect to sell any additional shares of our common stock to Yorkville under the SEPA. Any issuance and sale by us under the SEPA
of a substantial amount of shares of common stock in addition to the 22,381,878 shares of common stock being registered for resale by
Yorkville under the registration statement that includes this prospectus could cause additional substantial dilution to our stockholders.

The issuance of our common
stock to Yorkville pursuant to the SEPA, the Promissory Note or the YA Debenture will not affect the rights or privileges of our existing
stockholders, except that the economic and voting interests of each of our existing stockholders will be diluted. Although the number
of shares of our common stock that our existing stockholders own will not decrease, the shares of our common stock owned by our existing
stockholders will represent a smaller percentage of our total outstanding shares of our common stock after any such issuance.

Other Information

We are not selling any securities
under this prospectus and will not receive any of the proceeds from the sale of our common stock by the Selling Securityholder. However,
we expect to receive proceeds from sales of common stock that we may elect to make to Yorkville pursuant to the SEPA, if any, from time
to time in our discretion. The net proceeds from sales, if any, under the SEPA, will depend on the frequency and prices at which we sell
shares of common stock to Yorkville after the date of this prospectus.

We received (i) $1,710,000 upon the issuance of
the Promissory Note in connection with the Pre-Paid Advance made on the Effective Date of the SEPA and (ii) proceeds of $9,000,000 from
the issuance and sale by us to Yorkville of the YA Debenture. If we exercise our right to issue further shares of our common stock pursuant
to the SEPA, we may receive up to an additional proceeds in connection with such Advances after the date of this prospectus, subject to
the further limitations and terms and conditions of the SEPA. The net proceeds from sales, if any, under the SEPA, will depend on the
frequency and prices at which we sell shares of common stock to Yorkville after the date of this prospectus. See “ Selling
Securityholder ” on page 99 of this prospectus for additional information regarding the Selling Securityholder.

The Selling Securityholder
may sell or otherwise dispose of the common stock described in this prospectus in a number of different ways and at varying prices. Yorkville
is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended (the “ Securities
Act ”), only with respect to advances under the SEPA and any profits on the sales of shares of our common stock by Yorkville
acquired under the SEPA and any discounts, commissions, or concessions received by Yorkville are deemed to be underwriting discounts and
commissions under the Securities Act. If any underwriters, dealers, or agents are involved in the sale of any of the securities, their
names and any applicable purchase price, fee, commission, or discount arrangement between or among them will be set forth, or will be
calculable from the information set forth, in any applicable prospectus supplement. Yorkville is not an “underwriter” within
the meaning of Section 2(a)(11) of the Securities Act with respect to the shares of our common stock issuable upon conversion of the Promissory

We will pay the expenses
incurred in registering under the Securities Act the offer and sale of the shares of the common stock to which this prospectus relates
by the Selling Securityholder, including our legal and accounting fees. See “Plan of Distribution” on page 114 of this
prospectus for more information. No securities may be sold without delivery of this prospectus and any applicable prospectus supplement
describing the method and terms of the offering of such securities. You should carefully read this prospectus and any applicable prospectus

Potential Dilution

As of May 15, 2026, there
were 145,819,663 shares of our common stock outstanding of which approximately 108.9 million shares were held by non-affiliates of our
company. If all of the 22,381,878 shares offered for resale by the Selling Securityholder under this prospectus were issued and outstanding
as of the date hereof, such shares would represent approximately 13.3% of the total number of outstanding shares of common stock and approximately
17.0% of the total number of outstanding shares of common stock held by non-affiliates of our company, in each case as of May 15, 2026.

Summary Risk Factors

Below is a summary of material
factors that make an investment in our securities speculative or risky. Importantly, this summary does not address all of the risks and
uncertainties that we face.

|
● |
We have a history of losses that may continue in the future; our management has identified conditions that raise substantial doubt about our ability to continue as a going concern; and we may not achieve profitability or generate positive cash flow. |

|
  |
  |

|
● |
We may need to raise additional funding to finance our operations. This additional financing may not be available on acceptable terms or at all. Failure to obtain this necessary capital when needed may force us to curtail planned programs or cease operations entirely. |

|
  |
  |

|
● |
Raising additional funds may cause dilution to existing stockholders and/or may restrict our operations or require us to relinquish proprietary rights. |

|
  |
  |

|
● |
We have identified material weaknesses in our internal controls over financial reporting. As a result of these material weaknesses, we previously identified material errors to our interim results for the thirteen weeks ended March 30, 2025, the thirteen and twenty-six weeks ended June 29, 2025, and the thirteen and thirty-nine weeks ended September 28, 2025 (the “Prior Periods”) and determined that the Prior Periods included in our Quarterly Reports on Form 10-Q for the quarters ended March 30, 2025, June 29, 2025, and September 28, 2025 should no longer be relied upon and should be restated. If we are unable to maintain effective internal controls over financial reporting and disclosure controls and procedures, the accuracy and timeliness of our financial and operating reporting may be adversely affected, and confidence in our operations and disclosures may be lost. |

|
● |
We face risks related to the restatement of our previously issued quarterly financial statements. |

|
● |
Our failure to prepare and timely file our periodic reports with the SEC limits our access to the public markets to raise debt or equity capital. |

● | Our
business depends in part on the availability of rebates, tax credits and other financial incentives. The OBBBA has materially reduced
the availability of these rebates, credits or incentives, which may adversely impact our business. |

8

● | Macroeconomic conditions in
our domestic and international markets, as well as inflation concerns, instability of financial institutions, rising interest rates,
and recessionary concerns may adversely affect our industry, business and financial results. |

|
● |
We have incurred losses and may be unable to achieve or sustain profitability in the future. |

|
  |
  |

|
● |
We face competition from both traditional energy companies and renewable energy companies. |

|
  |
  |

|
● |
Our growth strategy depends on the widespread adoption of solar power technology. |

|
  |
  |

|
● |
We are exposed to the credit risk of customers and our finance partners, and payment delinquencies on accounts receivables. |

|
  |
  |

|
● |
Any unauthorized access to or disclosure or theft of personal information we gather, store or use could harm our reputation and subject us to claims or litigation. |

|
● |
Our success depends on the continuing contributions of key personnel, including Thurman J. Rodgers. If we are unable to attract and retain key employees and qualified personnel, our business and prospects could be harmed. |

|
● |
Our operating results and ability to grow may fluctuate from quarter to quarter and year to year, which could make future performance difficult to predict and could cause operating results for a particular period to fall below expectations. |

|
  |
  |

|
● |
We may be subject to breaches of our information technology systems, which could lead to disclosure of internal information, damage to our reputation or relationships with dealers, suppliers, and customers, and disrupt access to online services. Such breaches could subject us to significant reputational, financial, legal, and operational consequences. |

|
  |
  |

|
● |
We are subject to legal proceedings and regulatory inquiries and may be named in additional claims or legal proceedings or become involved in regulatory inquiries, all of which are costly, distracting to our core business and could result in an unfavorable outcome or harm our business, financial condition, results of operations or the trading price for our securities. |

|
  |
  |

|
● |
Our Directors, executive officers and principal stockholders will continue to have significant influence over our company, which could limit your ability to influence the outcome of key transactions, including a change of control. |

|
  |
  |

|
● |
If we fail to meet all applicable requirements of Nasdaq and Nasdaq determines to delist our common stock, the delisting could adversely affect the market liquidity of our common stock and the market price of our common stock could decrease. |

|
  |
  |

|
● |
We may be required to repurchase up to 5,618,488 shares of common stock from the investors with whom we entered into Forward Purchase Agreements in connection with the closing of the Business Combination, which would reduce the amount of cash available to us to fund our growth plan. |

|
  |
  |

|
● |
Our 10.0% Senior Secured Notes are secured obligations, and there are risks associated with our 10.0% Senior Secured Notes that could adversely affect our business and financial condition. |

|
  |
  |

|
● |
The conversion features of the Convertible Senior Notes and Yorkville Notes may adversely affect our financial condition and operating results. |

|
  |
  |

|
● |
The issuance of common stock to the Selling Securityholder may cause substantial dilution to our existing shareholders, and the sale of such shares acquired by the Selling Securityholder could cause the price of our common stock to decline. |

|
● |
Future sales (including potential sales of securities to Yorkville pursuant to the SEPA), or the perception of future sales, by us or our stockholders in the public market could cause the market price for the common stock to decline. |

Risk
Factors

Investing in our securities
involves a high degree of risk. You should carefully consider the risks and uncertainties described below together with all of the other
information contained in this prospectus, including our financial statements and related notes appearing at the end of this prospectus
and in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before
deciding to invest in our securities. If any of the events or developments described below were to occur, our business, prospects, operating
results and financial condition could suffer materially, the trading price of our common stock could decline, and you could lose all or
part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties
not presently known to us or that we currently believe to be immaterial may also adversely affect our business.

Risks Related to our Businesses and Industry

We have a history of
losses that may continue in the future; our management has identified conditions that raise substantial doubt about our ability to continue
as a going concern; and we may not achieve profitability or generate positive cash flow.

Since
our inception, we have incurred losses and negative cash flows from operations. We incurred a net loss from continuing operations of
$44.3 million in the fiscal year ended December 28, 2025 and of $19.2 million in in the thirteen weeks ended March 29, 2026. We had an
accumulated deficit of $451.5 million as of March 29, 2026. We have current debt of $38.0 million, and notes payable and derivative liabilities,
net of current portion of $131.8 million, as of March 29, 2026, as well as other current and long-term liabilities (including the liability
we recorded relating to a litigation matter with Siemens). We had cash and cash equivalents, excluding restricted cash, of $9.5 million
as of March 29, 2026, which was held for working capital expenditures. These conditions raise substantial doubt about our ability to
continue as a going concern. Our ability to continue as a going concern requires that we obtain sufficient funding, either through external
financial transactions or cash flows generated from operations, to meet our obligations and finance our operations.

If we are not able to secure
adequate additional funding, either through external financial transactions or cash flows generated from operations, when needed, we will
need to reevaluate our operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate
assets where possible, or suspend or curtail planned programs or cease operations entirely. These actions could materially impact our
business, results of operations and future prospects. There can be no assurance that in the event we require additional financing, such
financing will be available on terms that are favorable, or at all.

We may not achieve profitability
or positive cash flow for a number of reasons, including declines in revenue, as well as increases in costs of our products, U.S. and
global macroeconomic trends, including with respect to the impact of U.S. trade tariffs and the imposition of additional tariffs applicable
to our industry or our products. In addition, we may be unable to identify further cost savings opportunities below present levels that
would not adversely impact the functioning of our existing operations needed to meet customer and regulatory requirements. If we fail
to generate sufficient revenue to support our operations, we may not be able to achieve profitability or generate sufficient cash flow
to meet our financial obligations and our liquidity position will be negatively impacted. See “Management’s Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” and “Notes to Consolidated Financial
Statements - (1) Organization - (c) Liquidity and Going Concern” for a further discussion of the other factors that may impact
our liquidity position.

Failure to generate sufficient
cash flows from operations, raise additional capital or reduce certain discretionary spending would have a material adverse effect on
our ability to achieve our intended business objectives.

11

We may need to raise
additional funding to finance our operations. This additional financing may not be available on acceptable terms or at all. Failure to
obtain this necessary capital when needed may force us to curtail planned programs or cease operations entirely.

Our operations have consumed
significant amounts of cash since inception. We expect to incur significant operating expenses as we continue to grow our business, including
expenses incurred in connection with acquisitions and the further integration of acquired businesses, including the SunPower Businesses,
Sunder, Ambia and Cobalt. We anticipate that our operating losses and negative operating cash flows will continue into the foreseeable
future.

We had cash and cash equivalents,
excluding restricted cash, of $9.5 million as of March 29, 2026. Our cash position raises substantial doubt regarding our ability to continue
as a going concern for 12 months after the consolidated financial statements issuance. Further, we cannot guarantee that our business
will generate sufficient cash flow from operations to fund our operations or liquidity needs. Over time, we expect that we will need to
raise additional funds through the issuance of additional equity, equity-related or debt securities or through obtaining credit from financial
institutions to fund, together with our principal sources of liquidity, any significant unplanned or accelerated expenses and new strategic
investments.

We will require substantial
additional capital to continue operations. Such additional capital might not be available when we need it and our actual cash requirements
might be greater than anticipated. Additionally, the ability to raise additional financing depends on numerous factors that are outside
our control, including general economic and market conditions, interest rates, the health of financial institutions, investors’
and lenders’ assessments of our prospects and the prospects of the solar industry in general. We cannot be certain that additional
capital will be available on attractive terms, if at all, when needed, which could be dilutive to stockholders, and our financial condition,
results of operations, business and prospects could be materially and adversely affected. If the financial markets become difficult or
costly to access, including due to rising interest rates, inflation, fluctuations in exchange rates or other changes in geopolitical or
economic conditions, including, without limitation, with respect to tariffs and trade policies, our ability to raise additional capital
may be negatively impacted. Our failure to raise capital in the future would have a negative impact on our ability to expand our business.

Raising additional
funds may cause dilution to existing stockholders and/or may restrict our operations or require us to relinquish proprietary rights.

To the extent that we raise
additional capital by issuing equity, convertible debt or other convertible securities, our existing stockholders may experience substantial
dilution, and the terms of these issued securities may include liquidation or other preferences that adversely affect the rights of our
existing common stockholders. For example, we may issue debt or equity securities under our shelf registration statement, through our
at-the-market offering facility, through our existing equity line of credit with White Lion (as defined below), through our standby equity
purchase facility with Yorkville or we may issue additional debt or equity securities in private transactions. Any agreements for future
debt or preferred equity financings, if available, may involve covenants limiting or restricting our ability to take specific actions,
such as raising additional capital, incurring additional debt, making capital expenditures or declaring dividends. Our ability to use
our at-the-market offering facility or shelf registration statement are currently constrained by the size of our non-affiliate market
capitalization, our trading volume and other factors, and there can be no assurance regarding the price at which we will be able to sell
such shares, and any sales of our common stock under our at-the-market offering facility, and any offerings we might complete under our
shelf registration statement, may be at prices that result in additional dilution to our existing stockholders. Further, as a result of
our current ineligibility to use Form S-3, we currently cannot use our at-the-market offering facility or conduct securities offerings
using our shelf registration statement. If we incur additional debt, the debt holders, together with holders of our outstanding Convertible
Senior Notes and the Yorkville Notes (each as defined below), would have rights senior to holders of common stock to make claims on our
assets, and the terms of any future debt could restrict our operations, including our ability to pay dividends on our common stock.

12

We have identified
material weaknesses in our internal controls over financial reporting. As a result of these material weaknesses, we identified material
errors to our interim results for the thirteen weeks ended March 30, 2025, the thirteen and twenty-six weeks ended June 29, 2025, and
the thirteen and thirty-nine weeks ended September 28, 2025 (the “Prior Periods”) and we have determined that the Prior Periods
included in our Quarterly Reports on Form 10-Q for the quarters ended March 30, 2025, June 29, 2025, and September 28, 2025 should no
longer be relied upon and should be restated. If we are unable to maintain effective internal controls over financial reporting and disclosure
controls and procedures, the accuracy and timeliness of our financial and operating reporting may be adversely affected, and confidence
in our operations and disclosures may be lost.

In connection with the preparation
and audit of our financial statements for the year ended December 28, 2025, our management identified material weaknesses in our internal
control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial
reporting, such that a reasonable possibility exists that a material misstatement of annual or interim financial statements would not
be prevented or detected on a timely basis. The material weaknesses are as follows:

The Company did not maintain
controls to execute the criteria established in the COSO Framework for (i) the control environment, (ii) risk assessment, (iii) control
activities, (iv) information and communication, and (v) monitoring activities.

Each of the control deficiencies
identified below constitute a material weakness, either individually or in the aggregate.

Control Environment.
Our Company did not maintain an effective control environment and identified the following material weakness: our Company lacked appropriate
policies and resources to develop and operate effective internal control over financial reporting and a lack of appropriate and consistent
IT policies given the significant volume of financially relevant IT changes, which contributed to the Company’s inability to properly
analyze, record and disclose accounting matters timely and accurately.

Control Activities.
Our Company did not design and implement effective control activities and identified the following material weakness:

|
● |
Ineffective design and operation of certain control activities due to significant personnel changes throughout fiscal 2025. Control deficiencies, which aggregate to a material weakness, occurred within substantially all areas of financial reporting. |

13

Information and Communication.
Our Company did not design and implement effective information and communication activities and identified the following material
weaknesses :

|
● |
Our Company did not design and maintain effective general information technology controls over logical access and program change management for our key information systems used to support the financial reporting process. Specifically, management did not maintain effective controls to ensure proper segregation of duties related to user administration and other privileged access functions and in implementing program changes in information systems. Due to the pervasive nature of these deficiencies, business process controls that are dependent upon information from these systems were also not effective. |

|
● |
Our Company did not have adequate processes and controls for communicating information among the accounting, finance, operations, and legal departments, necessary to support the proper functioning of internal controls. |

Monitoring Activities.
Our Company did not design and implement effective monitoring activities and identified the following material weaknesses: (i) failure
to adequately monitor compliance with accounting policies, procedures and controls related to substantially all areas of financial reporting;
and (ii) failure to properly select, develop and perform ongoing evaluations of the components of internal controls (including the monitoring
of service providers’ control environments).

These material weaknesses
described in the paragraphs above contributed to material accounting errors identified and corrected during the audit of our Company’s
financial statements. Additionally, in connection with the preparation of our audited financial statements for the year ended December,
28, 2025, and as a result of these material weaknesses, we identified material errors to our interim results for the thirteen weeks ended
March 30, 2025, the thirteen and twenty-six weeks ended June 29, 2025, and the thirteen and thirty-nine weeks ended September 28, 2025
(the “Prior Periods”) and we determined that the Prior Periods included in our Quarterly Reports on Form 10-Q for the quarters
ended March 30, 2025, June 29, 2025, and September 28, 2025 (the “Prior Filings”) should no longer be relied upon and should
be restated. If we fail to adequately remediate these material weaknesses, there could be material misstatements that may not be prevented
or detected.

We have taken certain steps,
such as recruiting additional personnel, in addition to utilizing third-party consultants and specialists, to supplement our internal
resources, to enhance our internal control environment and plan to take additional steps to remediate the material weaknesses. Although
we plan to complete this remediation process as quickly as possible, we cannot estimate how long it will take. We cannot provide assurance
that the measures we have taken to date, and may take in the future, will be sufficient to remediate the control deficiencies that led
to our material weakness in internal control over financial reporting or that such measures will prevent or avoid potential future material
weaknesses.

If we are not able to maintain
effective internal control over financial reporting and Disclosure Controls and procedures, or if material weaknesses are discovered in
future periods, a risk that is significantly increased in light of the complexity of our business, we may be unable to accurately and
timely report our financial position, results of operations, cash flows or key operating metrics, which could result in late filings of
the annual and quarterly reports under the Exchange Act (and which would limit our ability to use Form S-3 and may impact the availability
of Rule 144), restatements of financial statements or other corrective disclosures, an inability to access commercial lending markets,
defaults under our convertible notes and outstanding loans and other agreements, or other material adverse effects on our business, reputation,
results of operations, financial condition or liquidity.

14

We face risks related
to the restatement of our previously issued quarterly financial statements.

As a result of our determination
that the Prior Filings should no longer be relied upon and should be restated, we face a number of additional risks and uncertainties,
which may affect investor confidence in the accuracy of our financial disclosures and may raise reputation issues for our business. For
example, we may face potential litigation or other disputes, which may include claims relating to federal and state securities laws, contractual
claims and other claims arising from the restatement of the Prior Filings and the material weaknesses in our internal control over financial
reporting and the preparation of our financial statements. We may discover additional errors in our previously filed financial statements.
We cannot ensure that all of the risks and challenges described above will be eliminated or that general reputational harm will not persist.
If one or more of the foregoing risks or challenges persist, our business, operations and financial condition are likely to be materially
and adversely affected.

Our failure to prepare
and timely file our periodic reports with the SEC limits our access to the public markets to raise debt or equity capital.

We did not file our Quarterly
Report on Form 10-Q for the quarter ended March 29, 2026, our Annual Report on Form 10-K for the fiscal year ended December 29, 2024,
our Quarterly Report on Form 10-Q for the quarter ended September 28, 2025 or the amendment required to our Current Report originally
filed on September 26, 2025 relating to the Sunder acquisition within the timeframe required by the SEC. Accordingly, we are not currently
eligible to use a registration statement on Form S-3 that would allow us to continuously incorporate by reference our SEC reports into
the registration statement, to use “shelf” registration statements to conduct offerings, or to use our at-the-market offering
facility until approximately one year from the date we have regained and maintain status as a current filer. Our inability to use Form
S-3 may significantly impair our ability to raise necessary capital to fund our operations and execute our strategy. If we seek to access
the capital markets through a registered offering during the period of time that we are unable to use Form S-3, we may be required to
publicly disclose the proposed offering and the material terms thereof before the offering commences, we may experience delays in the
offering process due to SEC review of a Form S-1 registration statement and we may incur increased offering and transaction costs and
other considerations. If we are unable to raise capital through a registered offering, we would be required to conduct our equity financing
transactions on a private placement basis, which may be subject to pricing, size and other limitations imposed under the Nasdaq rules,
or seek other sources of capital. The foregoing limitations on our financing approaches could prevent us from pursuing transactions or
implementing business strategies that would be beneficial to our business.

Changes in international
trade policies, tariffs, or trade disputes could significantly and adversely affect our business, revenues, margins, results of operations,
and cash flows.

On February 7, 2018, safeguard
tariffs on imported solar cells and modules (“ CSPV ”) went into effect pursuant to Proclamation 9693, which approved
recommendations to provide relief to U.S. manufacturers and impose safeguard tariffs on imported solar cells and modules, based on the
investigations, findings, and recommendations of the U.S. International Trade Commission (the “ International Trade Commission ”).
On February 4, 2022, then President Biden issued Proclamation 10339 extending the existing safeguard measures on U.S. imports of CSPV
products by an additional four years until February 6, 2026. Prior to the termination of the safeguard tariffs, modules were subject to
a tariff rate of approximately 15%. Cells were subjected to a tariff-rate quota, under which the first 5 GW of cell imports each year
was exempt from tariffs, and cells imported after the 5 GW quota was reached were subject to the same approximately 15% tariff as modules
in the first year, with the same 0.25% decline in each of the three subsequent years. The tariff-free cell quota applied globally, without
any allocation by country or region.

While solar cells and modules
based on interdigitated back contact technology were excluded from these safeguard tariffs, our solar products based on other technologies
continue were subject to the safeguard tariffs until February 6, 2026.

15

Solar cells and panels from
various countries continue to be subject to U.S. antidumping, and countervailing duty (AD/CVD) actions in the United States. The U.S.
Department of Commerce (the “ Department of Commerce ”) maintains antidumping and countervailing duty orders on solar
cells as well as panels produced in China. In 2022, the Department of Commerce found that solar product producers in Cambodia, Malaysia,
Thailand, and Vietnam were circumventing the China AD/CVD actions. As a result, imports of solar products from these countries may be
treated as if they are of Chinese origin and therefore subject to the aforementioned antidumping and countervailing duty orders. On June
6, 2022, then President Biden issued an Executive Order allowing U.S. solar installers to import solar modules and cells from Cambodia,
Malaysia, Thailand and Vietnam free from certain duties for 24 months, along with other incentives designed to accelerate U.S. domestic
production of clean energy technologies. This moratorium ended in June 2024 and China-wide AD/CVD action now applies to imports from those
countries that contain Chinese-origin inputs. Additionally, on December 29, 2023, Auxin and Concept Clean Energy, Inc. filed suit in the
U.S. Court of International Trade challenging the legal basis for the moratorium and implementing regulations. In August 2025 the Court
of International Trade found the moratorium on the collection of AD/CVD duties to be unlawful and ordered retroactive collection of duties
that should have been paid during that period. The retroactive collection of duties was stayed pending appeal. On February 9, 2026, the
U.S. government withdrew its appeal of that decision, but other parties continue to pursue the appeal. In addition, on May 15, 2024 the
Department of Commerce and the U.S. International Trade Commission initiated antidumping and countervailing duty investigations of CSPV
products from Cambodia, Malaysia, Thailand, and Vietnam. Both the Department of Commerce and the U.S. International Trade Commission made
affirmative findings for all countries. On June 24, 2025, the Department of Commerce imposed antidumping and countervailing duty orders
on CSPV products from all four countries. Duty rates range zero to over 100% antidumping duties and approximately 15% to over 3000% countervailing
duties depending on the company and country. Antidumping and countervailing duties are assessed retroactively and thus final assessment
of duties on imports made after June 2025 will be determined in future proceedings by the Department of Commerce.

The high AD/CVD duty rates,
together with uncertainty surrounding the implications of existing tariffs affecting the U.S. solar market and potential trade tensions
between the U.S. and other countries has caused and is likely to cause further market volatility, price fluctuations, supply shortages,
and project delays, any of which could harm our business, and the pursuit of mitigating actions may divert substantial resources from
other projects.

Further, the Uyghur Forced
Labor Prevention Act may inhibit importation of certain solar modules or components. In addition, the imposition of tariffs is likely
to result in a wide range of impacts to the U.S. solar industry and the global manufacturing market, as well as our business in particular.
Such tariffs could materially increase the price of our solar products and result in significant additional costs to the Company, its
resellers, and the resellers’ customers, which could cause a significant reduction in demand for our solar power products and greatly
reduce our competitive advantage.

Our business depends
in part on the availability of rebates, tax credits and other financial incentives. The OBBBA has materially reduced the availability
of these rebates, credits or incentives, which may adversely impact our business.

U.S. federal, state and local
government bodies provide incentives to end users, distributors, system integrators and manufacturers of solar energy systems to promote
solar electricity in the form of rebates, tax credits and other financial incentives such as system performance payments, payments for
renewable energy credits associated with renewable energy generation and the exclusion of solar energy systems from property tax assessments.
These incentives enable us to lower the price charged to customers for energy and for solar energy systems. However, these incentives
may expire on a particular date, end when the allocated funding is exhausted or be reduced or terminated as solar energy adoption rates
increase. These reductions or terminations often occur without warning.

The Inflation Reduction Act
of 2022 (“ IRA ”) extended and modified prior law applicable to U.S. federal tax credits that are available with respect
to solar energy systems. Under the IRA, the following tax credits were generally available: (i) a production tax credit under Code Section
45 (for facilities that began construction before January 1, 2025) and Code Section 45Y (for facilities that are placed in service after
December 31, 2024) (the “ PTC ”) with respect to electricity produced from certain qualifying facilities, (ii) an investment
tax credit under Code Section 48 (for facilities that began construction before January 1, 2025) and Code Section 48E (for facilities
that are placed in service after December 31, 2024) (the “ ITC ”) in connection with the installation of certain solar
facilities and energy storage technology, and (iii) a residential clean energy credit (the “ Section 25D Credit ”) in
connection with the installation of qualifying property that uses solar energy to generate electricity for residential use.

On July 4, 2025, the One
Big Beautiful Bill Act (the “ OBBBA ”) was enacted and significantly modified the IRA’s clean energy incentive
framework by accelerating the termination of certain credits and adding new eligibility restrictions and compliance burdens. The OBBBA
effectively repealed, on an accelerated timeline, key federal tax incentives for solar projects by curtailing eligibility for the clean
electricity PTC and ITC for applicable solar facilities placed in service after December 31, 2027 (subject to grandfathering for projects
that begin construction by July 4, 2026) and by terminating the Section 25D Credit after 2025.

With respect to the PTC,
solar energy projects that began construction before January 1, 2025 generally remain eligible for the PTC under Section 45 (as amended
by the IRA) and generally are not subject to the accelerated phaseouts or other limitations introduced by the OBBBA. The PTC available
to a taxpayer in 2024 and prior taxable years under Code Section 45 generally is equal to a certain rate multiplied by the kilowatt hours
of electricity produced by the taxpayer from solar energy at a facility owned by it and sold to an unrelated party during that taxable
year. The base rates for the PTC under Code Section 45 is 0.3 cents (adjusted for inflation). This rate is increased to 1.5 cents (adjusted
for inflation) for projects that (i) have a maximum net output of less than one megawatt (measured in alternating current), (ii) begin
construction before January 29, 2023, and (iii) meet certain prevailing wage and apprenticeship requirements. It also may be increased
for projects that include a certain percentage of components produced in the U.S. and projects that are located in certain energy communities,
in each case subject to applicable requirements and IRS guidance.

The PTC under Code Section
45Y, the successor to Code Section 45 that is applicable for facilities placed in service after December 31, 2024, generally is similar
to the PTC under Code Section 45 but includes certain different terms and qualification requirements. The PTC amount under Code Section
45Y generally is equal to the PTC outlined above for Code Section 45, including the availability of the same increased credit rates under
the same circumstances. The PTC under Code Section 45Y applies to kilowatt hours of electricity produced at a “qualified facility,”
which generally is a facility, such as a solar energy facility, that generates electricity and has a greenhouse gas emission rate that
is not greater than zero.

16

Under the OBBBA, solar facilities
that begin construction after July 4, 2026 (one year after enactment of the OBBBA) are ineligible for the Code Section 45Y credit if placed
in service after December 31, 2027. Facilities that begin construction prior to July 4, 2026 are not subject to this accelerated placed-in-service
deadline. In addition, IRS guidance interpreting these OBBBA termination provisions imposes more stringent “beginning of construction”
requirements, increasing the risk that projects may fail to qualify if development timelines slip or if the taxpayer cannot satisfy the
applicable standards. Moreover, the OBBBA denies the Code Section 45Y for certain leased residential solar water heating property (while
generally excluding leased solar electric generating property from that denial). A facility is not eligible for the PTC under Code Section
45Y if a tax credit already is allowed with respect to the facility under Code Section 45, 48 or 48E (or certain other tax credit provisions)
for the taxable year or any prior taxable year.

With respect to the ITC,
solar energy projects that began construction before January 1, 2025 generally remain eligible for the ITC under Section 48 and are not
subject to the accelerated phaseouts or other limitations introduced by the OBBBA. The ITC available under Code Section 48E is the successor
provision of Code Section 48 and is applicable for investments in facilities placed in service after December 31, 2024. The ITC under
Code Section 48E generally is similar to the ITC outlined above under Code Section 48 in structure, including generally providing for
the same increased credit rates under the same circumstances. The ITC under Code Section 48E applies to investments in a “qualified
facility” and “energy storage technology”. A “qualified facility” for these purposes generally is the same
as described above for the PTC under Code Section 45Y and “energy storage technology” is defined by reference to such term
in Code Section 48.

Similar to Section 45Y, solar
facilities that begin construction after July 4, 2026 (one year after enactment) are ineligible for the Section 48E credit if placed in
service after December 31, 2027. This placed-in-service deadline would not apply to energy storage technology. Moreover, the OBBBA denies
the Code Section 48E for certain leased residential solar water heating property (while generally excluding leased solar electric generating
property from that denial). The ITC under Code Section 48E is subject to recapture if the Internal Revenue Service determines that the
greenhouse gas emissions rate for the facility exceeds a certain threshold. A facility is not eligible for the ITC under Code Section
48E if a tax credit already is allowed with respect to the facility under Code Section 45, 45Y or 48 (or certain other tax credit provisions)
for the taxable year or any prior taxable year.

Under the IRA, the Section
25D Credit available to a taxpayer is equal to the “applicable percentage” of expenditures for property that uses solar energy
to generate electricity for use in a dwelling unit located in the U.S. and used as a residence by the taxpayer. The applicable percentage
is 26% for such systems that are placed in service before January 1, 2022 and 30% for such systems that are placed in service after December
31, 2021. As modified by the OBBBA, the Section 25D Credit terminated with respect to expenditures made after December 31, 2025, and an
expenditure generally is treated as made when the original installation of the property is completed (or, in certain cases, when construction
or reconstruction is completed and the taxpayer’s original use of the structure begins). The unavailability of the Section 25D Credit
for systems when installation is completed after December 31, 2025 likely will impact the prices of our solar energy systems and overall
value proposition our solar systems provide to customers.

The OBBBA also introduces
additional restrictions relating to certain FEOC and supply chain sourcing, which may affect project eligibility and increase compliance
costs. On February 12, 2026, the U.S. Treasury Department and Internal Revenue Service released IRS Notice 2026-15, which provides additional
guidance regarding the prohibited foreign entity (“PFE”) rules under the OBBBA. In particular, this notice establishes interim
safe harbors for determining whether a project receives material assistance from a PFE, including guidance on calculation of the Material
Assistance Cost Ratio. While this guidance reduces certain uncertainties, it is interim in nature, and further rulemaking, including a
notice of proposed rulemaking and final regulations expected later in 2026, may modify or replace this framework. Such future guidance
could impose more restrictive requirements or additional compliance burdens, which may increase our costs and adversely affect our ability,
or our customers’ ability, to qualify for applicable tax credits. If we or our customers are unable to satisfy the PFE or related
eligibility requirements, it could materially and adversely affect our revenues, results of operations, cash flows and the overall demand
for our products.

The OBBBA has materially
reduced the governmental incentives available to participants in the solar industry, which is likely to adversely affect the results of
our operations and our ability to compete in this industry by increasing the cost of capital, causing us to increase the prices of our
energy and solar energy systems and reduce the size of our addressable market. Even where incentives remain available, evolving statutory
requirements and administrative guidance may create uncertainty, increase compliance costs, and delay or reduce tax credit financing,
which could disrupt project timelines and harm our liquidity.

Moreover, the U.S. federal
tax credits discussed above have complex legal and operational requirements, including with respect to “beginning of construction”
and placed-in-service requirements. There also may be uncertainty as to how such requirements promulgated under the IRA or the OBBBA are
interpreted. If Internal Revenue Service guidance regarding implementation of the IRA or the OBBBA is viewed by investors as unclear,
tax credit financing may be delayed or downsized, harming our ability to secure financing for customers. Our failure to either (i) interpret
the new requirements under the IRA and the OBBBA regarding among other things, timing of construction, prevailing wage, apprenticeship,
domestic content, siting in an “energy community,” accurately or (ii) adequately update our supply-chain, manufacturing, installation,
and record-keeping processes to meet such requirements, may result a partial or full reduction in the related U.S. federal tax benefit,
and our customers, financiers and shareholders may require us to indemnify them for certain of such reductions.

17

We are an “emerging
growth company” and a “smaller reporting company” and we cannot be certain if the reduced reporting requirements applicable
to these companies will make our common stock less attractive to investors.

We are an “emerging
growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). For as long as we continue to be an emerging
growth company, we intend to take advantage of exemptions from various reporting requirements that apply to other public companies that
are not emerging growth companies, including:

|
● |
not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended (the “ Sarbanes-Oxley Act ”); |

|
● |
not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board (the “ PCAOB ”) regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements; |

|
● |
reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and |

|
● |
exemptions from the requirements of holding nonbinding advisory stockholder votes on executive compensation and stockholder approval of any golden parachute payments not previously approved. |

Under the JOBS Act, emerging
growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies.
We have elected to avail ourselves of this exemption from new or revised accounting standards and, therefore, will not be subject to the
same new or revised accounting standards as other public companies that are not emerging growth companies. As a result, our financial
statements may be different from companies that comply with the new or revised accounting pronouncements as of public company effective
dates.

We will remain an emerging
growth company until the earliest to occur of: (1) the last day of the fiscal year in which we have at least $1.235 billion in total annual
gross revenues; (2) the date we qualify as a “large accelerated filer,” with at least $700.0 million of equity securities
held by non-affiliates; (3) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior
three-year period; and (4) the last day of the fiscal year ending after the fifth anniversary of our IPO.

Even after we no longer qualify
as an emerging growth company, we may still qualify as a “smaller reporting company,” as defined in the Exchange Act, which
generally would allow us to continue to take advantage of many of the same exemptions from disclosure requirements, including providing
only two years of audited financial statements, not being required to comply with the auditor attestation requirements of Section 404
of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation our periodic reports and proxy statements,
unless we are also an accelerated filer, in which case different requirements will apply.

We cannot predict if investors
will find our securities less attractive because we may rely on these exemptions. If some investors find our common stock less attractive
as a result, there may be a less active trading market for our securities and the trading price of our securities may be more volatile.

Macroeconomic conditions
in our domestic and international markets, as well as inflation concerns, instability of financial institutions, rising interest rates,
and recessionary concerns may adversely affect our industry, business and financial results.

Our business depends on the
overall demand for our solar energy products and on the economic health and willingness of our customers and potential customers to purchase
our products and services. As a result of macroeconomic or market uncertainty, including inflation concerns, rising interest rates, recessionary
concerns, and geopolitical conflicts, customers may decide to delay purchasing our products and services or not purchase at all. In addition,
a number of the risks associated with our business, which are disclosed in these risk factors, may increase in likelihood, magnitude or
duration, and we may face new risks that we have not yet identified.

18

In the past, unfavorable
macroeconomic and market conditions have resulted in sustained periods of decreased demand. Macroeconomic and market conditions could
be adversely affected by a variety of political, economic or other factors in the U.S. and international markets, which could, in turn,
adversely affect spending levels of installers and end users and could create volatility or deteriorating conditions in the markets in
which we operate. Macroeconomic uncertainty or weakness could result in:

|
● |
reduced demand for our products as a result of constraints on spending for solar energy systems by our customers and/or a reduction in government subsidies for renewable energy investments; |

|
● |
increased price competition for our products that may adversely affect revenue, gross margin and profitability; |

|
● |
the introduction of any disadvantageous trade regulations and import duties and tariffs; |

|
● |
decreased ability to forecast operating results and make decisions about budgeting, planning and future investments; |

|
● |
decrease in the popularity of solar energy as a green energy solution; |

|
● |
business and financial difficulties faced by our suppliers or other partners, including impacts to material costs, sales, liquidity levels, ability to continue investing in their businesses, ability to import or export goods, ability to meet development commitments and manufacturing capability; and |

|
● |
increased   overhead and production costs as a percentage of revenue. |

Reductions in customer spending
in response to unfavorable or uncertain macroeconomic and market conditions, globally or in a particular region where we operate, would
adversely affect our business, results of operations and financial condition.

Existing regulations
and policies, including trade policies and tariffs, and changes to these regulations and policies, including changes to trade policies
and tariffs, may present technical, regulatory, and economic barriers to the purchase and use of solar power products, which may significantly
reduce demand for our products and services.

The market for electric generation
products is heavily influenced by federal, state and local government laws, geopolitical forces (such as trade policies and tariffs),
regulations and policies concerning the electric utility industry in the U.S. and abroad, as well as policies promulgated by electric
utilities. These regulations and policies often relate to electricity pricing and technical interconnection of customer-owned electricity
generation, and trade and policy changes that make solar power less competitive with other power sources could deter investment in the
research and development of alternative energy sources as well as customer purchases of solar power technology, which could in turn result
in a significant reduction in the demand for our solar power products. The market for electric generation equipment is also influenced
by geopolitics, trade and local content laws, policies and tariffs, regulations and policies that can discourage growth and competition
in the solar industry and create economic barriers to the purchase of solar power products, thus reducing demand for our solar products.
In addition, on-grid applications depend on access to the grid, which is also regulated by government entities. We anticipate that our
solar power products and our installation will continue to be subject to oversight and regulation in accordance with federal, state, local
and foreign regulations relating to construction, safety, environmental protection, utility interconnection and metering, trade, and related
matters. It is difficult to track the requirements of individual states or local jurisdictions and design equipment to comply with the
varying standards. In addition, the U.S. and European Union, among others, have imposed tariffs or are in the process of evaluating the
imposition of tariffs on solar panels, solar cells, polysilicon, and potentially other components. These and any other tariffs or similar
taxes or duties may increase the price of our solar products and adversely affect our cost reduction roadmap, which could harm our results
of operations and financial condition. We cannot predict what actions may be taken by the United States or other countries with respect
to trade policies and tariffs or with respect to other policies and incentives that impact the solar industry, or that promote other forms
of energy production over the solar industry. Any new regulations or policies pertaining our solar power products may result in significant
additional expenses for our customers, which could cause a significant reduction in demand for our solar power products.

19

We rely on net metering
and related policies to offer competitive pricing to customers in many of our current markets and changes to net metering policies may
significantly reduce demand for electricity from residential solar energy systems.

Net metering is one of several
key policies that have enabled the growth of distributed generation solar energy systems in the U.S., providing significant value to customers
for electricity generated by their residential solar energy systems but not directly consumed on-site. Net metering allows a homeowner
to pay his or her local electric utility for power usage net of production from the solar energy system or other distributed generation
source. Homeowners receive a credit for the energy an interconnected solar energy system generates in excess of that needed by the home
to offset energy purchases from the centralized utility made at times when the solar energy system is not generating sufficient energy
to meet the customer’s demand. In many markets, this credit is equal to the residential retail rate for electricity and in other
markets, such as Hawaii and Nevada, the rate is less than the retail rate and may be set, for example, as a percentage of the retail rate
or based upon a valuation of the excess electricity. In some states and utility territories, customers are also reimbursed by the centralized
electric utility for net excess generation on a periodic basis.

Net metering programs have
been subject to legislative and regulatory scrutiny in some states and territories including, but not limited to, California, New Jersey,
Arizona, Nevada, Connecticut, Florida, Maine, Kentucky, Puerto Rico and Guam. These jurisdictions, by statute, regulation, administrative
order or a combination thereof, have recently adopted or are considering new restrictions and additional changes to net metering programs
either on a state-wide basis or within specific utility territories. Many of these measures were introduced and supported by centralized
electric utilities. These measures vary by jurisdiction and may include a reduction in the rates or value of the credits customers are
paid or receive for the power they deliver back to the electrical grid, caps or limits on the aggregate installed capacity of generation
in a state or utility territory eligible for net metering, expiration dates for and phasing out of net metering programs, replacement
of net metering programs with alternative programs that may provide less compensation and limits on the capacity size of individual distributed
generation systems that can qualify for net metering. Net metering and related policies concerning distributed generation also received
attention from federal legislators and regulators.

In California, the California
Public Utilities Commission (“ CPUC ”) issued an order in 2016 retaining retail-based net metering credits for residential
customers of California’s major utilities as part of Net Energy Metering 2.0 (“ NEM 2.0 ”). Under NEM 2.0, new
distributed generation customers receive the retail rate for electricity exported to the grid, less certain non-by passable fees. Customers
under NEM 2.0 also are subject to interconnection charges and time-of-use rates. Existing customers who receive service under the prior
net metering program, as well as new customers under the NEM 2.0 program, currently are permitted to remain covered by them on a legacy
basis for a period of 20 years. On September 3, 2020, the CPUC opened a new proceeding to review its current net metering policies and
to develop Net Energy Metering 3.0 (“ NEM 3.0 ”), also referred to by the CPUC as the NEM 2.0 successor tariff. NEM 3.0
was finalized on December 15, 2022 and includes several changes from previous net metering plans. The changes instituted by NEM 3.0 impacted
the amount that homeowners with solar power will be able to recuperate when selling excess energy back to the utility grid. With NEM 3.0,
the value of the credits for net exports are tied to the state’s Distributed Energy Resources Avoided Cost Calculator Documentation
(“ ACC ”). Another significant change with NEM 3.0 relates to the netting period: the time period over which the utilities
measure the clean energy being imported or exported. In general, longer netting periods have typically been advantageous for solar power
customers because production can offset any consumption. NEM 3.0 will instead measure energy using instantaneous netting, which means
interval netting approximately every 15 minutes. This will lead to more NEM customers’ electricity registering as exports, now valued
at the new, lower ACC value. Overall, the institution on NEM 3.0 has resulted in a smaller market for residential solar systems and it
is not certain that market conditions will improve or that NEM 3.0 will be amended or replaced with a more solar-friendly rate structure.
Other states may adopt policies similar to NEM 3.0 that cause deterioration to other residential solar markets.

Any shortage, delay
or component price change from these suppliers or delays and price increases associated with the product transport logistics could result
in sales and installation delays, cancellations and loss of market share.

We purchase solar panels,
inverters and other system components from a number of suppliers for certain components; however, we may be susceptible to quality issues,
shortages and price changes. If we fail to develop, maintain and expand relationships with existing or new suppliers, we may be unable
to adequately meet anticipated demand for our solar energy systems or may only be able to offer our systems at higher costs or after delays.
If one or more of the suppliers that we rely upon to meet anticipated demand ceases or reduces production, we may be unable to satisfy
this demand due to an inability to quickly identify alternate suppliers or to qualify alternative products on commercially reasonable
terms.

In particular, there are
a limited number of inverter and battery suppliers. Once we design a system for use with a particular inverter or battery, if that type
of inverter or battery is not readily available at an anticipated price, we may incur additional delay and expense to redesign the system
and source alternative inventory.

20

In addition, production of
solar panels involves the use of numerous raw materials and components. Several of these have experienced periods of limited availability,
particularly polysilicon, as well as indium, cadmium telluride, aluminum and copper. The manufacturing infrastructure for some of these
raw materials and components has a long lead time, requires significant capital investment and relies on the continued availability of
key commodity materials, potentially resulting in an inability to meet demand for these components. The prices for these raw materials
and components fluctuate depending on global market conditions and demand and we may experience rapid increases in costs or sustained
periods of limited supplies.

Despite efforts to obtain
components from multiple sources whenever possible, many suppliers may be single-source suppliers of certain components. If we cannot
maintain long-term supply agreements or identify and qualify multiple sources for components, access to supplies at satisfactory prices,
volumes and quality levels may be harmed. We may also experience delivery delays of components from suppliers in various global locations.
In addition, while there are alternative suppliers and service providers that we could enter into agreements with to replace our suppliers
on commercially reasonable terms, we may be unable to establish alternate supply relationships or obtain or engineer replacement components
in the short term, or at all, at favorable prices or costs. Qualifying alternate suppliers or developing our own replacements for certain
components may be time-consuming and costly and may force us to make modifications to our product designs.

Our need to purchase supplies
globally and our continued international expansion further subjects us to risks relating to currency fluctuations. Any decline in the
exchange rate of the U.S. dollar compared to the functional currency of component suppliers could increase component prices. In addition,
the state of the financial markets could limit suppliers’ ability to raise capital if they are required to expand their production
to meet our needs or satisfy our operating capital requirements. Changes in economic and business conditions, wars, governmental changes
and other factors beyond our control or which we do not presently anticipate, could also affect suppliers’ solvency and ability
to deliver components on a timely basis. Any of these shortages, delays or price changes could limit our growth, cause cancellations or
adversely affect profitability and the ability to compete in the markets in which we operate effectively.

Our business substantially
focuses on solar service agreements and transactions with residential customers.

Our business substantially
focuses on solar service agreements and transactions with residential customers. Our energy system sales to homeowners utilize power purchase
agreements (“ PPAs ”), leases, loans and other products and services. We currently offer PPAs and leases through Goodleap,
LLC, LightReach, EverBright, LLC, Dividend Solar Loan Company and other financial institutions. If we were unable to arrange new or alternative
financing methods for PPAs and leases on favorable terms, our business, financial condition, results of operations, and prospects could
be materially and adversely affected.

If we fail to manage
operations and growth effectively, we may be unable to execute our business plan, maintain high levels of customer service or adequately
address competitive challenges.

We have experienced significant
growth in recent periods (including through the integration of acquired companies) as measured by our number of customers, and we intend
to continue efforts to expand our business within existing and new markets. This growth (including these integration activities) has placed,
and any future growth may place, a strain on management, operational and financial infrastructure. Our growth requires our management
to devote a significant amount of time and effort to maintain and expand relationships with customers, dealers and other third parties,
attract new customers and dealers, arrange financing for growth and manage expansion into additional markets.

In addition, our current
and planned operations, personnel, information technology and other systems and procedures might need to be revised to support future
growth and may require us to make additional unanticipated investments in its infrastructure. Our success and ability to further scale
our business will depend, in part, on our ability to manage these changes in a cost-effective and efficient manner.

If we cannot manage operations
and growth, we may be unable to meet expectations regarding growth, opportunity and financial targets, take advantage of market opportunities,
execute our business strategies or respond to competitive pressures. This could also result in declines in quality or customer satisfaction,
increased costs, difficulties in introducing new offerings or other operational difficulties. Any failure to effectively manage our operations
and growth could adversely impact our reputation, business, financial condition, cash flows and results of operations.

21

We have incurred losses
and may be unable to achieve or sustain profitability in the future.

We have incurred net losses in the past, including a net loss from
continuing operations of $44.3 million in the fiscal year ended December 28, 2025. We had an accumulated deficit of $451.5 million as
of March 29, 2026. Additionally, as of March 29, 2026, we had current indebtedness of $38.0 million and long-term indebtedness, including
derivative liabilities, net of current of $131.8 million. We will continue to incur net losses as spending increases to finance the expansion
of operations, installation, engineering, administrative, sales and marketing staffs, spending increases on brand awareness and other
sales and marketing initiatives and implement internal systems and infrastructure to support the Company’s growth. We do not know
whether revenue will grow rapidly enough to absorb these costs, and our limited operating history makes it difficult to assess the extent
of these expenses or their impact on results of operations. Our ability to achieve profitability depends on a number of factors, including
but not limited to:

● | Growing the customer base; |

|
● |
Maintaining or further lowering the cost of capital; |

● | Reducing the cost of components
for our solar service offerings; |

|
● |
Growing and maintaining our sales partner network; |

|
● |
Growing our direct-to-consumer and New Homes business to scale; and |

|
● |
Reducing operating costs by lowering customer acquisition costs and optimizing our design and installation processes and supply chain logistics. |

Even if we do achieve profitability,
we may be unable to sustain or increase profitability in the future.

A material drop in
the retail price of utility-generated electricity or electricity from other sources could adversely impact our ability to attract customers,
which would harm our business, financial condition, and results of operations.

We believe a homeowner’s
decision to buy solar energy from us is primarily driven by a desire to lower electricity costs. Decreases in the retail prices of electricity
from utilities or other energy sources would harm our ability to offer competitive pricing and could harm its business. The price of electricity
from utilities could decrease as a result of:

|
● |
the construction of a significant number of new power generation plants, including nuclear, coal, natural gas or renewable energy technologies; |

|
● |
the construction of additional electric transmission and distribution lines; |

|
● |
a reduction in the price of natural gas or other natural resources as a result of new drilling techniques or other technological developments, a relaxation of associated regulatory standards, or broader economic or policy developments; |

|
● |
energy conservation technologies and public initiatives to reduce electricity consumption; |

|
● |
subsidies impacting electricity prices, including in connection with electricity generation and transmission; and |

|
● |
development of new energy technologies that provide less expensive energy. |

A reduction in utility electricity
prices would make the purchase of our solar service offerings less attractive. If the retail price of energy available from utilities
were to decrease due to any of these or other reasons, we would be at a competitive disadvantage. As a result, we may be unable to attract
new homeowners and growth would be limited.

22

We face competition
from both traditional energy companies and renewable energy companies.

The solar energy and renewable
energy industries are both highly competitive and continually evolving as participants strive to distinguish themselves within their markets
and compete with large utilities. Our primary competitors are the traditional utilities that supply energy to potential customers. We
compete with these utilities primarily based on price, predictability of price and the ease by which customers can switch to electricity
generated by our solar energy systems. If we cannot offer compelling value to its customers based on these factors, then our business
will not grow. Utilities generally have substantially greater financial, technical, operational and other resources than us. As a result
of their greater size, these competitors may be able to devote more resources to the research, development, promotion and sale of their
products or respond more quickly to evolving industry standards and changes in market conditions than we can. Utilities could also offer
other value added products and services that could help them compete with us even if the cost of electricity they offer is higher than
ours. In addition, utilities’ diversified generation portfolios which may allow utilities to sell electricity more cheaply than
electricity generated by our solar energy systems.

Our growth strategy
depends on the widespread adoption of solar power technology.

The distributed residential
solar energy market is at a relatively early stage of development compared to fossil fuel-based electricity generation. If additional
demand for distributed residential solar energy systems fails to develop sufficiently or takes longer to develop than we anticipate, the
Company may be unable to originate additional solar service agreements and related solar energy systems and energy storage systems to
grow the business. In addition, demand for solar energy systems and energy storage systems in our targeted markets may not develop to
the extent it anticipates. As a result, we may need to successfully broaden our customer base through origination of solar service agreements
and related solar energy systems and energy storage systems within its current markets or in new markets we may enter.

Many factors may affect the
demand for solar energy systems, including, but not limited to, the following:

|
● |
availability, substance and magnitude of solar support programs including government targets, subsidies, incentives, renewable portfolio standards and residential net metering rules; |

|
● |
the relative pricing of other conventional and non-renewable energy sources, such as natural gas, coal, oil and other fossil fuels, wind, utility-scale solar, nuclear, geothermal and biomass; |

|
● |
performance, reliability and availability of energy generated by solar energy systems compared to conventional and other non-solar renewable energy sources; |

|
● |
availability and performance of energy storage technology, the ability to implement such technology for use in conjunction with solar energy systems and the cost competitiveness such technology provides to customers as compared to costs for those customers reliant on the conventional electrical grid; and |

|
● |
general economic conditions and the level of interest rates. |

The residential solar energy
industry is constantly evolving, which makes it difficult to evaluate our prospects. We cannot be certain if historical growth rates reflect
future opportunities or its anticipated growth will be realized. The failure of distributed residential solar energy to achieve, or its
being significantly delayed in achieving, widespread adoption could have a material adverse effect on our business, financial condition
and results of operations.

Our business could
be adversely affected by seasonal trends, poor weather, labor shortages, and construction cycles.

Our business is subject to
significant industry-specific seasonal fluctuations. In the U.S., many customers make purchasing decisions towards the end of the year
in order to take advantage of tax credits and residential solar sales tend to decline during the winter months. In addition, sales in
the new home development market are often tied to construction market demands, which tend to follow national trends in construction, including
declining sales during cold weather months.

23

Natural disasters,
terrorist activities, political unrest, economic volatility, and other outbreaks could disrupt our delivery and operations, which could
materially and adversely affect our business, financial condition, and results of operations.

Global pandemics or fear
of spread of contagious diseases, such as Ebola virus disease (EVD), coronavirus disease 2019 (COVID-19), Middle East respiratory syndrome
(MERS), severe acute respiratory syndrome (SARS), H1N1 flu, H7N9 flu, avian flu and monkeypox, as well as hurricanes, earthquakes, tsunamis,
or other natural disasters could disrupt our business operations, reduce or restrict operations and services, incur significant costs
to protect its employees and facilities, or result in regional or global economic distress, which may materially and adversely affect
business, financial condition, and results of operations. Actual or threatened war, terrorist activities, political unrest, civil strife,
future disruptions in access to bank deposits or lending commitments due to bank failures and other geopolitical uncertainty could have
a similar adverse effect on our business, financial condition, and results of operations. On February 24, 2022, the Russian Federation
launched an invasion of Ukraine that has had an immediate impact on the global economy resulting in higher energy prices and higher prices
for certain raw materials and goods and services which in turn is contributing to higher inflation in the U.S. and other countries across
the globe with significant disruption to financial markets. Any one or more of these events may impede our operation and delivery efforts
and adversely affect sales results, or even for a prolonged period of time, which could materially and adversely affect our business,
financial condition, and results of operations. We cannot predict the full effects the supply chain constraints will have on our business,
cash flows, liquidity, financial condition and results of operations at this time due to numerous uncertainties.

We are exposed to the
credit risk of customers and our finance partners, and payment delinquencies on accounts receivables.

Defaults by customers and
the financial institutions that fund some of our customers’ solar systems have not been material to date, but we expect that the
risk of customer defaults or financial partner defaults may increase as we grow our business. For example, Sunnova Energy International,
Inc. (“Sunnova”), a major provider of financing for solar systems, announced that substantial doubt exists regarding its ability
to continue as a going concern. While the Company does not use Sunnova for any of its customer financing, if any of our financing partners
experience liquidity concerns or stop funding projects, we may incur significant losses or project delays. If any of our customers are
unable to make milestone payments on systems purchased in cash, our revenue and costs could be adversely affected. If economic conditions
worsen, certain of our customers or finance partners may face liquidity concerns and may be unable to satisfy their payment obligations
to us on a timely basis or at all, which could have a material adverse effect on our financial condition and results of operations.

We may not realize
the anticipated benefits of past or future acquisitions, including the transactions under the asset purchase agreement with the SunPower
Debtors, the Sunder Acquisition, the Ambia Acquisition and the Cobalt Acquisition and integration of these acquisitions may disrupt our
business.

In November 2022, we acquired
The Solaria Corporation (“ Solaria ”), after which Complete Solar was renamed “Complete Solaria, Inc.” In
October 2023, we subsequently sold solar panel assets of Solaria, including intellectual property and customer contracts, to Maxeon Solar
Technologies, Ltd., which resulted in an impairment loss of $147.5 million and loss on disposal of $1.8 million. On September 30, 2024,
we completed the acquisition of the Acquired SunPower Assets under the APA with the SunPower Debtors, which resulted in our acquisition
of the SunPower Businesses and a significant expansion of our business operations and headcount. On September 21, 2025, we entered into
an agreement to acquire Sunder and completed the Sunder Acquisition effective September 24, 2025. On November 21, 2025, we entered into
an agreement to acquire Ambia and completed the Ambia Acquisition on November 21, 2025. We completed the acquisition of Cobalt on February
2, 2026. In the future, we may acquire additional companies, project pipelines, products, or technologies, or enter into joint ventures
or other strategic initiatives. Our ability as an organization to integrate acquisitions is unproven. We may not realize the anticipated
benefits of our acquisitions or any other future acquisition or the acquisition may be viewed negatively by customers, financial markets
or investors.

24

Any acquisition has numerous
risks, including, but not limited to, the following:

|
● |
difficulty in assimilating the operations and personnel of the acquired company; |

|
● |
difficulty in effectively integrating the acquired technologies or products with current products and technologies; |

|
● |
difficulty in maintaining controls, procedures and policies during the transition and integration; |

|
● |
disruption of ongoing business and distraction of management and employees from other opportunities and challenges due to integration issues; |

|
● |
difficulty integrating the acquired company’s accounting, management information and other administrative systems; |

|
● |
inability to retain key technical and managerial personnel of the acquired business; |

|
● |
inability to retain key customers, vendors, and other business partners of the acquired business; |

|
● |
inability to achieve the financial and strategic goals for the acquired and combined businesses; |

|
● |
incurring acquisition-related costs or amortization costs for acquired intangible assets that could impact operating results; |

|
● |
failure of due diligence processes to identify significant issues with product quality, legal and financial liabilities, among other things; |

|
● |
inability to assert that internal controls over financial reporting are effective; and |

|
● |
inability to obtain, or obtain in a timely manner, approvals from governmental authorities, which could delay or prevent such acquisitions. |

|
● |
inability to rebuild trust with home builders due to the bankruptcy of the SunPower Debtors. |

|
● |
inability to obtain advantageous financing arrangements with financiers in order to pass the saving on to customers. |

We may be required
to file claims against other parties for infringing its intellectual property that may be costly and may not be resolved in its favor.

To protect our intellectual
property rights and to maintain competitive advantage, we have filed, and may continue to file, suits against parties we believe infringe
or misappropriate our intellectual property. Intellectual property litigation is expensive and time-consuming, could divert management’s
attention from our business, and could have a material adverse effect on our business, operating results, or financial condition, and
our enforcement efforts may not be successful. In addition, the validity of our patents may be challenged in such litigation. Our participation
in intellectual property enforcement actions may negatively impact our financial results.

Developments in technology
or improvements in distributed solar energy generation and related technologies or components may materially adversely affect demand for
our offerings.

Significant developments
in technology, such as advances in distributed solar power generation, energy storage solutions such as batteries, energy storage management
systems, the widespread use or adoption of fuel cells for residential or commercial properties or improvements in other forms of distributed
or centralized power production may materially and adversely affect demand for our offerings and otherwise affect our business. Future
technological advancements may result in reduced prices to consumers or more efficient solar energy systems than those available today,
either of which may result in current customer dissatisfaction. We may not be able to adopt these new technologies as quickly as its competitors
or on a cost-effective basis.

25

Additionally, recent technological
advancements may impact our business in ways not currently anticipated. Any failure by us to adopt or have access to new or enhanced technologies
or processes, or to react to changes in existing technologies, could result in product obsolescence or the loss of competitiveness of
and decreased consumer interest in its solar energy services, which could have a material adverse effect on its business, financial condition
and results of operations.

Our business is subject
to complex and evolving data protection laws. Many of these laws and regulations are subject to change and uncertain interpretation and
could result in claims, increased cost of operations or otherwise harm its business.

Consumer personal privacy
and data security have become significant issues and the subject of rapidly evolving regulation in the U.S. Furthermore, federal, state
and local government bodies or agencies have in the past adopted, and may in the future adopt, more laws and regulations affecting data
privacy. For example, the state of California enacted the California Consumer Privacy Act of 2018 (“ CCPA ”) and California
voters recently approved the California Privacy Rights Act (“ CPRA ”). The CCPA creates individual privacy rights for
consumers and places increased privacy and security obligations on entities handling the personal data of consumers or households. The
CCPA went into effect in January 2020 and it requires covered companies to provide new disclosures to California consumers, provides such
consumers, business-to-business contacts and employees new ways to opt-out of certain sales of personal information, and allows for a
new private right of action for data breaches. The CPRA modifies the CCPA and imposes additional data protection obligations on companies
doing business in California, including additional consumer rights processes and opt outs for certain uses of sensitive data. The CCPA
and the CPRA may significantly impact the Company’s business activities and require substantial compliance costs that adversely
affect its business, operating results, prospects and financial condition. To date, we have not experienced substantial compliance costs
in connection with fulfilling the requirements under the CCPA or CPRA. However, we cannot be certain that compliance costs will not increase
in the future with respect to the CCPA and CPRA or any other recently passed consumer privacy regulation.

Outside the U.S., an increasing
number of laws, regulations, and industry standards may govern data privacy and security. For example, the European Union’s General
Data Protection Regulation (“ EU GDPR ”) and the United Kingdom’s GDPR (“ UK GDPR ”) impose strict
requirements for processing personal data. Under the EU GDPR, companies may face temporary or definitive bans on data processing and other
corrective actions; fines of up to 20 million Euros or 4% of annual global revenue, whichever is greater; or private litigation related
to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent
their interests. Non-compliance with the UK GDPR may result in substantially similar adverse consequences to those in relation to the
EU GDPR, including monetary penalties of up to £17.5 million or 4% of worldwide revenue, whichever is higher.

In addition, we may be unable
to transfer personal data from Europe and other jurisdictions to the U.S. or other countries due to data localization requirements or
limitations on cross-border data flows. Europe and other jurisdictions have enacted laws requiring data to be localized or limiting the
transfer of personal data to other countries. In particular, the European Economic Area (“ EEA ”) and the United Kingdom
have significantly restricted the transfer of personal data to the U.S. and other countries whose privacy laws it believes are not adequate.
Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross- border data transfer laws. Although
there are currently various mechanisms that may be used to transfer personal data from the EEA and UK to the U.S. in compliance with law,
such as the EEA and UK’s standard contractual clauses, these mechanisms are subject to legal challenges, and there is no assurance
that the Company can satisfy or rely on these measures to lawfully transfer personal data to the U.S. If there is no lawful manner for
us to transfer personal data from the EEA, the UK, or other jurisdictions to the U.S., or if the requirements for a legally-compliant
transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of its operations,
the need to relocate part of or all of its business or data processing activities to other jurisdictions at significant expense, increased
exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other
third parties, and injunctions against its processing or transferring of personal data necessary to operate its business. Some European
regulators have ordered certain companies to suspend or permanently cease certain transfers out of Europe for allegedly violating the
EU GDPR’s cross-border data transfer limitations.

Any inability to adequately
address privacy and security concerns, even if unfounded, or comply with applicable privacy and data security laws, regulations and policies,
could result in additional cost and liability to us damage our reputation, inhibit sales and adversely affect our business. Furthermore,
the costs of compliance with, and other burdens imposed by, the laws, regulations and policies that are applicable to our business may
limit the use and adoption of, and reduce the overall demand for, its solutions. If we are not able to adjust to changing laws, regulations
and standards related to privacy or security, our business may be harmed.

26

Any unauthorized access
to or disclosure or theft of personal information we gather, store or use could harm our reputation and subject us to claims or litigation.

We receive, store and use
personal information of customers, including names, addresses, e-mail addresses, and other housing and energy use information. We also
store information of dealers, including employee, financial and operational information. We rely on the availability of data collected
from customers and dealers in order to manage our business and market our offerings. We take certain steps in an effort
