1.01. Entry

Into a Material Definitive Agreement.

On

April 23, 2026, Lucid Diagnostics Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting

Agreement”) with Canaccord Genuity LLC and BTIG, LLC, as representatives (the “Representatives”) of the

underwriters named therein (the “Underwriters”), for an underwritten offering to the public of shares of the Company’s

common stock, par value $0.001 per share (the “Common Stock”), at a public offering price of $1.00 per share (the

“Offering”).

Pursuant

to the Underwriting Agreement, the Company agreed to sell, and the Underwriters agreed to purchase, 18,000,000 shares of Common Stock

(the “Shares”) at a price of $0.94 per share, representing an underwriting discount of $0.06 per share. The Company

also agreed to reimburse the Underwriters for certain expenses incurred in connection with the Offering, including their reasonable fees

and expenses of legal counsel, up to $75,000. The Underwriting Agreement is subject to customary closing conditions and contains customary

representations, warranties and covenants of the Company. In addition, the Company agreed to indemnify the Underwriters against certain

liabilities, including for certain liabilities under the Securities Act of 1933, as amended (the “Securities Act”).

Canaccord

Genuity LLC and BTIG, LLC are acting as joint bookrunners of the Offering.

The

gross proceeds of the Offering, before deducting the underwriting discount and the expenses of the Offering, will be $18,000,000. The

sale of the Shares is expected to close on or about April 24, 2026, subject to the customary closing conditions contained in the Underwriting

Agreement.

The

Offering was made pursuant to the Company’s existing shelf registration statement on Form S-3 (Registration No. 333-291981), which

was filed with the Securities and Exchange Commission (“SEC”) on December 5, 2025 and declared effective by the SEC

on March 26, 2026, and a prospectus supplement thereto, which will be filed with the SEC in accordance with Rule 424 under the Securities

Act.

The

Underwriting Agreement is attached hereto as Exhibit 1.1 and is incorporated herein by reference. A copy of the opinion of Graubard Miller

relating to the legality of the issuance and sale of the securities in the Offering is attached hereto as Exhibit 5.1. The foregoing

description of the Offering by the Company and the documentation related thereto does not purport to be complete and is qualified in

its entirety by reference to such exhibits, which are incorporated herein by reference.

The

Underwriting Agreement has been included to provide investors and security holders with information regarding its terms. The agreement

is not intended to provide any other factual information about the Company. The representations, warranties and covenants contained in

the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the

agreed upon by the contracting parties.

and file with the Commission a final prospectus supplement to the Base Prospectus relating to the Securities and the offering thereof

in accordance with the provisions Rule 430B and Rule 424(b) of the Rules and Regulations. Such final supplemental form of prospectus

“Prospectus.” Any reference herein to the Base Prospectus or the Prospectus shall be deemed to refer to include

the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the date of such prospectus.

“included” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus (or other references

Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration

Statement, the Base Prospectus or the Prospectus shall be deemed to mean and include the subsequent filing of any document under the

Upon the filing or first use within the meaning of the Rules and Regulations, the Prospectus (or any supplement to either) conformed

Company or any Subsidiary (as defined below) in the preceding three years not having been convicted of a felony or misdemeanor or having

been made the subject of a judicial or administrative decree or order as described in Rule 405 of the Rules and Regulations (without

(C)

with the Act, and when taken together with the Time of Sale Disclosure Package as of the Time of Sale, did not contain any untrue statement

of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances

under which they were made, not misleading.

(v)

filed with the Commission under the Securities Act or the Exchange Act or became or become effective under the Securities Act, as the

case may be, conformed or will conform in all material respects with the requirements of the Securities Act and the Exchange Act, as

applicable.

(vii)

Financial Information. The consolidated financial statements of the Company included or incorporated by reference in the Registration

Statement, the Time of Sale Disclosure Package, the Prospectus and the Issuer Free Writing Prospectus, if any, together with the related

notes and schedules, present fairly, in all material respects, the consolidated financial position of the Company and the Subsidiaries

(as defined below) as of the dates indicated and the consolidated results of operations, cash flows and changes in stockholders’

equity of the Company for the periods specified and have been prepared in compliance with the requirements of the Securities Act and

Exchange Act and in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) applied on a consistent

basis during the periods involved; the other financial and statistical data with respect to the Company and the Subsidiaries (as defined

below) contained or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package, the Prospectus and

the Issuer Free Writing Prospectuses, if any, are accurately and fairly presented and prepared on a basis consistent with the financial

statements and books and records of the Company; there are no financial statements (historical or pro forma) that are required to be

included or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package or the Prospectus that are not

included or incorporated by reference as required; the Company and the Subsidiaries (as defined below) do not have any material liabilities

or obligations, direct or contingent (including any off-balance sheet obligations), not described in the Registration Statement (excluding

the exhibits thereto), the Time of Sale Disclosure Package and the Prospectus, other than liabilities incurred in the ordinary course

of business; and all disclosures contained or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package,

the Prospectus and the Issuer Free Writing Prospectuses, if any, regarding “non-GAAP financial measures” (as such term is

defined by the rules and regulations of the Commission) comply with Regulation G of the Exchange Act and Item 10 of Regulation S-K under

the Securities Act, to the extent applicable. The interactive data in eXtensible Business Reporting Language included or incorporated

by reference in the Registration Statement, the Time of Sale Disclosure Package and the Prospectus fairly presents the information called

for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(viii)

Conformity with EDGAR Filing. The Prospectus delivered to the Underwriters for use in connection with the sale of the Securities

pursuant to this Agreement will be identical to the versions of the Prospectus created to be transmitted to the Commission for filing

via EDGAR, except to the extent permitted by Regulation S-T.

(ix)

Organization. The Company and each of its Subsidiaries are duly organized, validly existing as a corporation and in good standing

under the laws of their respective jurisdictions of organization. The Company and each of its Subsidiaries are duly licensed or qualified

as a foreign corporation for transaction of business and in good standing under the laws of each other jurisdiction in which their respective

ownership or lease of property or the conduct of their respective businesses requires such license or qualification, and have all corporate

power and authority necessary to own or hold their respective properties and to conduct their respective businesses as described in the

Registration Statement, the Time of Sale Disclosure Package and the Prospectus, except where the failure to be so qualified or in good

standing or have such power or authority would not, individually or in the aggregate, have a material adverse effect or would reasonably

be expected to have a material adverse effect on or affecting the assets, business, operations, earnings, properties, condition (financial

or otherwise), prospects, stockholders’ equity or results of operations of the Company and the Subsidiaries taken as a whole, or

prevent or materially interfere with consummation of the transactions contemplated hereby (a “Material Adverse Effect”).

(x)

Subsidiaries. The subsidiaries set forth on Exhibit 21.1 to the Company’s most recent Annual Report on Form 10-K (collectively,

the “Subsidiaries”), are the Company’s only significant subsidiaries (as such term is defined in Rule

1-02 of Regulation S-X promulgated by the Commission). Except as set forth in the Registration Statement, the Time of Sale Disclosure

Package and in the Prospectus, the Company owns, directly or indirectly, all of the equity interests of the Subsidiaries free and clear

of any lien, charge, security interest, encumbrance, right of first refusal or other restriction, and all the equity interests of the

Subsidiaries are validly issued and are fully paid, nonassessable and free of preemptive and similar rights. No Subsidiary is currently

prohibited, directly or indirectly, from paying any dividends to the Company, from making any other distribution on such Subsidiary’s

capital stock, from repaying to the Company any loans or advances to such Subsidiary from the Company or from transferring any of such

Subsidiary’s property or assets to the Company or any other Subsidiary of the Company.

(xi)

No Violation or Default. Neither the Company nor any of its Subsidiaries is (i) in violation of its charter or by-laws or similar

organizational documents; (ii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such

a default, in the due performance or observance of any term, covenant or condition contained in any indenture, mortgage, deed of trust,

loan agreement or other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or

any of its Subsidiaries is bound or to which any of the property or assets of the Company or any of its Subsidiaries are subject; or

(iii) in violation of any law or statute or any judgment, order, rule or regulation of any Governmental Authority (as defined below),

except, in the case of each of clauses (ii) and (iii) above, for any such violation or default that would not, individually or in the

aggregate, have a Material Adverse Effect. To the Company’s knowledge, no other party under any material contract or other agreement

to which it or any of its Subsidiaries is a party is in default in any respect thereunder where such default would have a Material Adverse

Effect. “Governmental Authority” means (i) any federal, provincial, state, local, municipal, national or international

government or governmental authority, regulatory or administrative agency, governmental commission, department, board, bureau, agency

or instrumentality, court, tribunal, arbitrator or arbitral body (public or private); (ii) any self-regulatory organization; or (iii)

any political subdivision of any of the foregoing.

(xii)

No Material Adverse Change. Subsequent to the respective dates as of which information is given in the Registration Statement,

the Time of Sale Disclosure Package, the Prospectus and the Free Writing Prospectuses, if any (including any document deemed incorporated

by reference therein), there has not been (i) any Material Adverse Effect or the occurrence of any development that the Company reasonably

expects will result in a Material Adverse Effect, (ii) any obligation or liability, direct or contingent (including any off-balance sheet

obligations), incurred by the Company or any Subsidiary, which is material to the Company and the Subsidiaries taken as a whole, (iii)

any material change in the capital stock or outstanding long-term indebtedness of the Company or any of its Subsidiaries or (iv) any

dividend or distribution of any kind declared, paid or made on the capital stock of the Company or any Subsidiary, other than in each

case above in the ordinary course of business or as otherwise disclosed in the Registration Statement or Prospectus (including any document

deemed incorporated by reference therein).

(xiii)

Capitalization. The issued and outstanding shares of capital stock of the Company have been validly issued, are fully paid and

nonassessable and, other than as disclosed in the Registration Statement, the Time of Sale Disclosure Package or the Prospectus, or as

have been satisfied or waived in connection with the Offering, are not subject to any preemptive rights, rights of first refusal or similar

rights. The Company has an authorized, issued and outstanding capitalization as set forth in the Registration Statement, the Time of

Sale Disclosure Package and the Prospectus as of the dates referred to therein (other than the grant of additional options shares of

restricted stock, or other stock-based awards under the Company’s existing stock option plans, or changes in the number of outstanding

shares of Common Stock of the Company due to the issuance of shares upon the exercise or conversion of securities exercisable for, or

convertible into, Common Stock outstanding on the date hereof) and such authorized capital stock conforms to the description thereof

set forth in the Registration Statement, the Time of Sale Disclosure Package and the Prospectus. The description of the securities of

the Company in the Registration Statement, the Time of Sale Disclosure Package and the Prospectus is complete and accurate in all material

respects. Except as disclosed in or contemplated by the Registration Statement, the Time of Sale Disclosure Package or the Prospectus,

as of the date referred to therein, the Company does not have outstanding any options to purchase, or any rights or warrants to subscribe

for, or any securities or obligations convertible into, or exchangeable for, or any contracts or commitments to issue or sell, any shares

of capital stock or other securities.

(xiv)

Authorization; Enforceability. The Company has full legal right, power and authority to enter into this Agreement and perform

the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Company and is a legal,

valid and binding agreement of the Company enforceable in accordance with its terms, except to the extent that enforceability may be

limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general

equitable principles.

(xv)

Authorization of Securities. The Securities, when issued and delivered pursuant to the terms approved by the board of directors

of the Company or a duly authorized committee thereof, or a duly authorized executive committee, against payment therefor as provided

herein, will be duly and validly authorized and issued and fully paid and nonassessable, free and clear of any pledge, lien, encumbrance,

security interest or other claim, including any statutory or contractual preemptive rights, resale rights, rights of first refusal or

other similar rights, and will be registered pursuant to Section 12 of the Exchange Act. The Securities, when issued, will conform to

the description thereof set forth in or incorporated into the Prospectus.

(xvi)

No Consents Required. No consent, approval, authorization, order, registration or qualification of or with any Governmental Authority

is required for the execution, delivery and performance by the Company of this Agreement, the issuance and sale by the Company of the

Securities, except for such consents, approvals, authorizations, orders and registrations or qualifications as may be required under

applicable state securities laws, or by the by-laws and rules of the Financial Industry Regulatory Authority (“FINRA”)

or the Exchange, in connection with the sale of the Securities to the Underwriters.

(xvii)

S-X promulgated under the Securities Act (each, a “Person”), has the right, contractual or otherwise, to cause

the Company to issue or sell to such Person any Common Stock or shares of any other capital stock or other securities of the Company,

(ii) no Person has any preemptive rights, resale rights, rights of first refusal, rights of co-sale, or any other rights (whether pursuant

to be filed and paid all taxes shown thereon through the date hereof, to the extent that such taxes have become due and are not being

contested in good faith, except where the failure to so file or pay would not have a Material Adverse Effect. Except as otherwise disclosed

adversely to the Company or any of its Subsidiaries which has had, or would have, individually or in the aggregate, a Material Adverse

them, good and valid title to all personal property described in the Registration Statement, the Time of Sale Disclosure Package or Prospectus

as being owned by them, in each case free and clear of all liens, encumbrances and claims, except those matters that (i) do not materially

interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries or (ii) would not, individually

or in the aggregate, have a Material Adverse Effect. Any real or personal property described in the Registration Statement, the Time

of Sale Disclosure Package or Prospectus as being leased by the Company and any of its Subsidiaries is held by them under valid, existing

and enforceable leases, except for such leases that are not valid, existing and enforceable that would not be reasonably expected, individually

applicable codes, laws and regulations (including, without limitation, building and zoning codes, laws and regulations and laws relating

to access to such properties), except if and to the extent disclosed in the Registration Statement, the Time of Sale Disclosure Package

or Prospectus or except for such failures to comply that would not, individually or in the aggregate, reasonably be expected to interfere

in any material respect with the use made and proposed to be made of such property by the Company and its Subsidiaries or otherwise have

a Material Adverse Effect. None of the Company or its subsidiaries has received from any Governmental Authorities any notice of any condemnation

of, or zoning change affecting, the properties of the Company and its Subsidiaries, and the Company knows of no such condemnation or

zoning change which is threatened, except for such that would not reasonably be expected to interfere in any material respect with the

use made and proposed to be made of such property by the Company and its Subsidiaries or otherwise have a Material Adverse Effect, individually

or in the aggregate.

or wastes, pollutants or contaminants, except, in the case of any of clauses (i), (ii) or (iii) above, for any such failure to comply

or failure to receive required permits, licenses, other approvals or liability as would not, individually or in the aggregate, have a

Material Adverse Effect.

(xxxiv)

Disclosure Controls. The Company and each of its Subsidiaries maintain systems of internal accounting controls designed to provide

reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii)

transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability;

(iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded

accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to

any differences. The Company’s internal control over financial reporting is effective and the Company is not aware of any material

weaknesses in its internal control over financial reporting (in each case, other than as set forth in the Prospectus). The Company has

established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such

disclosure controls and procedures to provide reasonable assurance that material information relating to the Company and each of its

Subsidiaries is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s

Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers

have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the Company’s most

recently completed fiscal quarter (such date, the “Evaluation Date”). The Company presented in its Form 10-Q

or Form 10-K for the fiscal period ended as of the Evaluation Date the conclusions of the certifying officers about the effectiveness

of the disclosure controls and procedures as of such date based on their evaluations of such controls and procedures and the disclosure

controls and procedures were effective as of such date. Since the Evaluation Date, there have been no significant changes in the Company’s

internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge,

in other factors that could significantly affect the Company’s internal controls (in each case, other than as set forth in the

Registration Statement, the Time of Sale Disclosure Package and the Prospectus).

as defined in Section 412 of the Code has been incurred, whether or not waived, and the fair market value of the assets of each such

plan (excluding for these purposes accrued but unpaid contributions) exceeds the present value of all benefits accrued under such plan

3.

Purchase, Sale and Delivery of Securities.

(a)

Securities. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and

conditions herein set forth, the Company agrees to issue and sell the Securities, to the several Underwriters, and each Underwriter agrees,

severally and not jointly, to purchase from the Company the number of Securities set forth opposite the name of such Underwriter in Schedule

I hereto. The purchase price for each Security shall be $0.94 per share. The obligation of each Underwriter to the Company shall be to

purchase from the Company that number of Securities (to be adjusted by the Representatives to avoid fractional shares) which represents

the same proportion of the number of Securities to be sold by the Company pursuant to this Agreement as the number of Securities set

forth opposite the name of such Underwriter in Schedule I hereto represents to the total number of Securities to be purchased by all

Underwriters pursuant to this Agreement. In making this Agreement, each Underwriter is contracting severally and not jointly; except

as provided in paragraph (c) of this Section 3 and in Section 8 hereof, the agreement of each Underwriter is to purchase only the respective

number of Securities specified in Schedule I.

The

Securities will be delivered by the Company to the Representatives for the accounts of the several Underwriters against payment of the

purchase price therefor by wire transfer of same day funds payable to the order of the Company, as appropriate, at the offices of Duane

Morris LLP, 22 Vanderbilt, 335 Madison Avenue, 23rd Floor, New York, NY 10017, or such other location as may be mutually acceptable,

at 10:00 a.m. Eastern time on the first (or if the Time of Sale occurs after 4:30 p.m. Eastern time, the second) full business day following

the date hereof, or at such other time and date as the Representatives and the Company determine pursuant to Rule 15c6-1(a) under the

Exchange Act, such time and date of delivery being herein referred to as the “Closing Date.”

(b)

Delivery. Delivery of the Securities will be made by credit through full fast transfer to the accounts at the Depository

Trust Company designated by the Representatives. In the event that the Securities are not delivered to the Representatives by 2:30 p.m.,

New York City time, on the Closing Date, the Company will return payment of the full purchase price to the Representatives via same day

funds by 4:30 p.m., New York City time. The Company shall remain liable to the Representatives for the full amount of the purchase price

and any costs associated with recovering the purchase price until the full amount has been received by the Representatives.

(c)

Purchase by Representatives on Behalf of Underwriters. It is understood that the Representatives, individually and not

as Representatives of the several Underwriters, may (but shall not be obligated to) make payment to the Company, on behalf of any Underwriter

for the Securities to be purchased by such Underwriter. Any such payment by the Representatives shall not relieve any such Underwriter

of any of its obligations hereunder. Nothing herein contained shall constitute any of the Underwriters an unincorporated association

or partner with the Company.

4.

Covenants.

(a)

Covenants of the Company. The Company covenants and agrees with the several Underwriters as follows:

(i)

Required Filings. During the period beginning on the date hereof and ending on the later of the Closing Date or such date,

as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered (assuming the absence

of Rule 172 under the Securities Act), in connection with sales by an Underwriter or dealer (the “Prospectus Delivery Period”),

prior to amending or supplementing the Registration Statement (including any Rule 462(b) Registration Statement), the Time of Sale Disclosure

Package or the Prospectus, the Company shall furnish to the Representatives for review a copy of each such proposed amendment or supplement,

and the Company shall not file any such proposed amendment or supplement to which the Representatives or counsel to the Underwriters

reasonably object. Subject to this Section 4(a)(i), immediately following execution of this Agreement, the Company will prepare the Prospectus

containing the Rule 430B Information and other selling terms of the Securities, the plan of distribution thereof and such other information

as may be required by the Securities Act or the Rules and Regulations or as the Representatives and the Company may deem appropriate,

and if requested by the Representatives, an issuer free writing prospectus containing the selling terms of the Securities and such other

information as the Company and the Representatives may deem appropriate, and will file or transmit for filing with the Commission, in

accordance with Rule 424(b) or Rule 433, as the case may be, copies of the Prospectus and each issuer free writing prospectus.

(ii)

Notification of Certain Commission Actions. During the Prospectus Delivery Period, the Company shall promptly advise the

Representatives in writing (A) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission,

(B) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to

the Time of Sale Disclosure Package or the Prospectus, (C) of the time and date that any post-effective amendment to the Registration

Statement becomes effective, (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration

Statement or any post-effective amendment thereto or of any order preventing or suspending its use or the use of the Time of Sale Disclosure

Package, the Prospectus or any issuer free writing prospectus, or (E) of any proceedings to remove, suspend or terminate from listing

or quotation the Common Stock from any securities exchange upon which it is listed for trading or included or designated for quotation,

or of the threatening or initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at

any time, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the

Company agrees that it shall comply with the provisions of Rules 424(b), 430A and 430B, as applicable, under the Securities Act and will

use its reasonable efforts to confirm that any filings made by the Company under Rule 424(b), Rule 433 or Rule 462 were received in a

timely manner by the Commission (without reliance on Rule 424(b)(8) or Rule 164(b)).

(iii)

Continued Compliance with Securities Laws. (A) During the Prospectus Delivery Period, the Company will comply as far as

it is able with all requirements imposed upon it by the Securities Act, as now and hereafter amended, and by the Rules and Regulations,

as from time to time in force, and by the Exchange Act so far as necessary to permit the continuance of sales of or dealings in the Securities

as contemplated by the provisions hereof, the Time of Sale Disclosure Package and the Prospectus. If during such period any event occurs

as a result of which the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure

Package) would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein,

in the light of the circumstances then existing, not misleading, or if during such period it is necessary or appropriate in the opinion

of the Company or its counsel or the Representatives or counsel to the Underwriters to amend the Registration Statement or supplement

the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) to comply

with the Securities Act or to file under the Exchange Act any document which would be deemed to be incorporated by reference in the Prospectus

in order to comply with the Securities Act or the Exchange Act, the Company promptly will (x) notify the Representatives of such untrue

statement or omission, (y) amend the Registration Statement or supplement the Prospectus (or, if the Prospectus is not yet available

to prospective purchasers, the Time of Sale Disclosure Package) or file such document (at the expense of the Company) so as to correct

such statement or omission or effect such compliance, and (z) notify the Representatives when any amendment to the Registration Statement

is filed or becomes effective or when any supplement to the Prospectus (or, if the Prospectus is not yet available to prospective purchasers,

the Time of Sale Disclosure Package) is filed.

(A)

If at any time following issuance of an issuer free writing prospectus there occurred or occurs an event or development as a result of

which such issuer free writing prospectus conflicted or would conflict with the information contained in the Registration Statement or

the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact

necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading,

the Company (x) has promptly notified or promptly will notify the Representatives of such conflict, untrue statement or omission, (y)

has promptly amended or will promptly amend or supplement, at its own expense, such issuer free writing prospectus to eliminate or correct

such conflict, untrue statement or omission, and (2) has notified or promptly will notify the Representatives when such amendment or

supplement was or is filed with the Commission where so required to be filed.

(B)

If immediately prior to the third anniversary of the initial effective date of the Registration Statement, any of the Securities remain

unsold by the Underwriters, the Company will prior to that third anniversary file, if it has not already done so, a new shelf registration

statement relating to the Securities, in a form satisfactory to the Representatives, will use its best efforts to cause such registration

statement to be declared effective within 180 days after that third anniversary, and will take all other action necessary or appropriate

to permit the public offering and sale of the Securities to continue as contemplated in the expired registration statement relating to

the Securities. References herein to the Registration Statement shall include such new shelf registration statement.

(iv)

Blue Sky Qualifications. The Company shall take or cause to be taken all necessary action to qualify the Securities for

sale under the securities laws of such jurisdictions as the Representatives reasonably designate and to continue such qualifications

in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith

to qualify as a foreign corporation (where not otherwise required), subject itself to taxation in any jurisdiction where not otherwise

required, or to execute a general consent to service of process in any jurisdiction (where not otherwise required).

(v)

Provision of Documents. The Company will furnish, at its own expense, to the Underwriters and counsel for the Underwriters

copies of the Registration Statement (three of which will be signed and will include all consents and exhibits filed therewith), and

to the Underwriters and any dealer the Time of Sale Disclosure Package, the Prospectus, any issuer free writing prospectus, and all amendments

and supplements to such documents, in each case as soon as available and in such quantities as the Representatives may from time to time

reasonably request.

(vi)

Rule 158. The Company will make generally available to its security holders as soon as practicable, but in no event later

than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering

a 12-month period that shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations.

(vii)

Payment and Reimbursement of Expenses. The Company, whether or not the transactions contemplated hereunder are consummated

or this Agreement is terminated, will pay or cause to be paid (A) all expenses (including transfer taxes allocated to the respective

transferees) incurred in connection with the delivery to the Underwriters of the Securities, (B) all expenses and fees (including, without

limitation, fees and expenses of the Company’s accountants and counsel but, except as otherwise provided below, not including fees

of the Underwriters’ counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration

Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Securities, the Time

printing, delivery, and shipping of this Agreement and other underwriting documents, including Blue Sky Memoranda (covering the states

and other applicable jurisdictions), (C) all filing fees and fees and the reasonable disbursements of the Underwriters’ counsel

incurred in connection with the qualification of the Securities for offering and sale by the Underwriters or by dealers under the securities

or blue sky laws of the states and other jurisdictions which the Representatives shall designate, (D) the fees and expenses of any transfer

agent or registrar, (E) the filing fees and fees and disbursements of Underwriters’ counsel incident to any required review and

limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production

of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the

prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and, with the prior approval

of the Company, any such consultants, and 50% of the cost of any aircraft chartered in connection with the road show (the remaining 50%

to be paid for by the Underwriters), (H) the reasonable fees and disbursements of counsel to the Underwriters in connection with the

transactions contemplated in this Agreement, and (I) all other costs and expenses of the Company incident to the performance of its obligations

the purposes set forth in the Time of Sale Disclosure Package and in the Prospectus.

or otherwise, except (A) to the Underwriters pursuant to this Agreement, (B) the issuance by the Company of shares of Common Stock upon

Sale Disclosure Package and the Prospectus; (C) the issuance by the Company of shares of Common Stock or securities convertible into

shares of Common Stock pursuant to the Company’s equity incentive plans in effect on the date hereof and described in the Registration

Prospectus as an issuer free writing prospectus, and has complied and will comply with the requirements of Rules 164 and 433 of the Rules

that otherwise would not be required to be filed by the Company thereunder, but for the action of the Company. Each Underwriter severally

represents and agrees that, (A) unless it obtains the prior written consent of the Company and the Representatives, it has not distributed,

the time period so required (without reliance on Rule 424(b)(8) or Rule 164(b)); the Registration Statement shall remain effective; no

stop order suspending the effectiveness of the Registration Statement or any part thereof, any Rule 462(b) Registration Statement, or

any amendment thereof, nor suspending or preventing the use of the Time of Sale Disclosure Package, the Prospectus or any issuer free

(b)

Continued Compliance with Securities Laws. No Underwriter shall have advised the Company that (i) the Registration Statement

any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d)

of the Rules and Regulations, any roadshow materials, or any Testing-the-Waters Communication or (ii) the omission or alleged omission

to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case

of the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, in light of the circumstances under which

they were made), and will reimburse each Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating

or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that

the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or

is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity

with written information furnished to the Company by the Representatives, or by any Underwriter through the Representatives, specifically

for use in the preparation thereof; it being understood and agreed that the only information furnished by an Underwriter consists of

the information described as such in Section 6(e).

(b)

Indemnification by the Underwriters. Each Underwriter will, severally and not jointly, indemnify and hold harmless the

Company, its affiliates, directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of

the Act and Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Company may become

subject, under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent

of such Underwriter), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are

based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Time of Sale

Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information

that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters

Communication, or any road show, or (ii) arise out of or are based upon the omission or alleged omission to state therein a material

fact required to be stated therein or necessary to make the statements therein not misleading (in the case of the Time of Sale Disclosure

Package, the Prospectus, or any amendment or supplement thereto, in light of the circumstances under which they were made), in each case

to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made

in reliance on or in conformity with written information furnished to the Company by the Representatives, or by such Underwriter through

the Representatives, specifically for use in the preparation thereof (it being understood and agreed that the only information furnished

by an Underwriter consists of the information described as such in Section 6(e)), and will reimburse the Company for any legal or other

expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability

or action as such expenses are incurred.

(c)

Notice and Procedures. Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the

commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party

under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying

party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such

indemnifying party has been materially prejudiced by such failure (through the forfeiture of substantive rights or defenses). In case

any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof,

the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying

party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice

from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the

indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred

by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however,

that if, in the sole reasonable judgment of the Representatives, it is advisable for the Underwriters to be represented as a group by

separate counsel, the Representatives shall have the right to employ a single counsel (in addition to local counsel) to represent the

Representatives and all Underwriters who may be subject to liability arising from any claim in respect of which indemnity may be sought

by the Underwriters under subsection (a) of this Section 6, in which event the reasonable fees and expenses of such separate counsel

shall be borne by the indemnifying party or parties and reimbursed to the Underwriters as incurred. An indemnifying party shall not be

obligated under any settlement agreement relating to any action under this Section 6 to which it has not agreed in writing. In addition,

no indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld

or delayed), effect any settlement of any pending or threatened proceeding unless such settlement includes an unconditional release of

such indemnified party for all liability on claims that are the subject matter of such proceeding and does not include a statement as

to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party. Notwithstanding the foregoing,

if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses

of counsel pursuant to this Section 6(c), such indemnifying party agrees that it shall be liable for any settlement effected without

its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid

request and (ii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the

date of such settlement.

(d)

Contribution; Limitations on Liability; Non-Exclusive Remedy. If the indemnification provided for in this Section 6 is

unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall

contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred

to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company

on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i)

above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to

in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the

statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion

as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts

and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative

fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the

omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’

relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company

and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were to be determined

by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which

does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an

indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d)

shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating

or defending against any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection

(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and

commissions received by such Underwriter with respect to the Securities purchased by it hereunder exceeds the amount of any damages that

such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from

any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute

are several in proportion to their respective underwriting obligations and not joint. The remedies provided for in this Section 6 are

not exclusive and shall not limit any rights or remedies that might otherwise be available to any indemnified party at law or in equity.

(e)

Information Provided by the Underwriters. The Underwriters severally confirm and the Company acknowledges that the statements

provided by the Underwriters to the Company in writing are correct and constitute the only information concerning such Underwriters furnished

in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, the Time of Sale

Disclosure Package, the Prospectus or any issuer free writing prospectus.

7.

Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company herein

or in certificates delivered pursuant hereto, including but not limited to the agreements of the several Underwriters, the Company contained

in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any

Underwriter or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive

delivery of, and payment for, the Securities to and by the Underwriters hereunder and any termination of this Agreement.

8.

the amount of Securities agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Securities in accordance

with the terms hereof, and the amount of Securities not purchased does not aggregate more than 10% of the total amount of Securities

set forth in Schedule I hereto, the remaining Underwriters shall be obligated to take up and pay for (in proportion to their respective

underwriting obligations hereunder as set forth in Schedule I hereto except as may otherwise be determined by the Representatives) the

Securities that the withdrawing or defaulting Underwriters agreed but failed to purchase.

(b)

Termination Under Certain Circumstances. If any Underwriter or Underwriters shall fail to take up and pay for the amount

of Securities agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Securities in accordance with

the terms hereof, and the amount of Securities not purchased aggregates more than 10% of the total amount of Securities set forth in

Schedule I hereto, and arrangements satisfactory to the Representatives for the purchase of such Securities by other persons are not

made within 36 hours thereafter, this Agreement shall terminate. In the event of any such termination the Company shall not be under

any liability to any Underwriter (except to the extent provided in Section 4(a)(vii), Section 4(b)(i), Section 4(b)(ii) and Section 6

hereof) nor shall any Underwriter (other than an Underwriter who shall have failed, otherwise than for some reason permitted under this

Agreement, to purchase the amount of Securities agreed by such Underwriter to be purchased hereunder) be under any liability to the Company

(except to the extent provided in Section 6 hereof).

(c)

Postponement of Closing. If Securities to which a default relates are to be purchased by the non-defaulting Underwriters

or by any other party or parties, the Representatives or the Company shall have the right to postpone the Closing Date for not more than

seven business days in order that the necessary changes in the Registration Statement, in the Time of Sale Disclosure Package, in the

Prospectus or in any other documents, as well as any other arrangements, may be effected. As used herein, the term “Underwriter”

includes any person substituted for an Underwriter under this Section 8.

if any, in respect of such default.

this Agreement by giving notice as hereinafter specified at any time at or prior to the Closing Date, if (i) the Company shall have failed,

refused or been unable, at or prior to such Closing Date, to perform any agreement on its part to be performed hereunder, (ii) any other

condition of the Underwriters’ obligations hereunder is not fulfilled, (iii) trading on the Nasdaq Stock Market or New York Stock

Exchange shall have been wholly suspended, (iv) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices

for securities shall have been required, on the Nasdaq Stock Market or New York Stock Exchange, by such exchange or by order of the Commission

or any other Governmental Authority, (v) a banking moratorium shall have been declared by federal or state authorities, or (vi) there

shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the

Representatives’ judgment, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the

sale of and payment for the Securities. Any such termination shall be without liability of any party to any other party except that the

provisions of Section 4(g) and Section 6 hereof shall at all times be effective.

(b)

Notice of Termination. If the Representatives elect to terminate this Agreement as provided in this Section, the Company

shall be notified promptly by the Representatives by telephone, confirmed by letter.

10.

Default by the Company.

(a)

Default by the Company. If the Company shall fail at the Closing Date to sell and deliver the number of Securities which

it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any Underwriter or, except

as provided in Section 4(a)(vii), Section 4(b)(i), Section 4(b)(ii) and Section 6 hereof, any non-defaulting party.

(b)

change such address for notices by sending to the parties to this Agreement written notice of a new address for such purpose.

12.

Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties

claim under or in respect of this Agreement or any provision herein contained. The term “successors and assigns” as herein

range of transactions which may involve interests that differ from those of the Company and that the Representatives have no obligation

to disclose such interest and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; (d) it has been

advised that the Representatives are acting, in respect of the transactions contemplated by this Agreement, solely for the benefit of

employees or creditors of the Company.

effective on March 26, 2026 (“Registration Statement”), and the offering by the Company pursuant thereto (the “Offering”)

of an aggregate of 18,000,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share

(“Common Stock”), in an underwritten offering to the public. The Company has entered into an underwriting agreement

(the “Underwriting Agreement”) with Canaccord Genuity LLC and BTIG, LLC, as the representatives of the underwriters

Act. This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In

hereinafter expressed.

Forward-Looking Statements

This

press release includes forward-looking statements that involve risk and uncertainties. Forward-looking statements are any statements

that are not historical facts. Such forward-looking statements, which are based upon the current beliefs and expectations of Lucid Diagnostics’

management, are subject to risks and uncertainties, which could cause actual results to differ from the forward-looking statements. Risks

and uncertainties that may cause such differences include, among other things, volatility in the price of Lucid Diagnostics’ common

stock; general economic and market conditions; the uncertainties inherent in research and development, including the cost and time required

to advance Lucid Diagnostics’ products to regulatory submission; whether regulatory authorities will be satisfied with the design

of and results from Lucid Diagnostics’ clinical and preclinical studies; whether and when Lucid Diagnostics’ products are

cleared by regulatory authorities; market acceptance of Lucid Diagnostics’ products once cleared and commercialized; Lucid Diagnostics’

ability to raise additional funding as needed; and other competitive developments. These factors are difficult or impossible to predict

accurately and many of them are beyond Lucid Diagnostics’ control. In addition, new risks and uncertainties may arise from time

to time and are difficult to predict. For a further list and description of these and other important risks and uncertainties that may

affect Lucid Diagnostics’ future operations, see Part I, Item 1A, “Risk Factors,” in Lucid Diagnostics’ most

recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, as the same may be updated in Part II, Item 1A,
