Item 5.03 Amendments to Articles of Incorporation

or Bylaws; Change in Fiscal Year.

On April 29, 2026, iSpecimen Inc. (the “Company”)

filed a Fifth Amended and Restated Certificate of Incorporation (the “Restated Certificate”) with the Secretary of State of

the State of Delaware, which, among other things, effectuated a reverse stock split of the Company’s issued and outstanding shares

of common stock, par value $0.0001 per share, at a ratio of 1-for-40 (the “Reverse Stock Split”). The Reverse Stock Split

became effective at 4:30 p.m. Eastern Time on April 27, 2026, and the Company’s common stock began trading on a split-adjusted basis

on the Nasdaq Capital Market (“Nasdaq”) when the market opened on April 28, 2026. The Company’s common stock continues

to trade on Nasdaq under the symbol “ISPC.” The new CUSIP number for the Company’s common stock following the Reverse

Stock Split is 45032V306.

At the Company’s special meeting of stockholders

held on October 30, 2025 (the “Special Meeting”), the Company’s stockholders approved a proposal to amend the Company’s

Fourth Amended and Restated Certificate of Incorporation (the “Prior Certificate”) to effect a reverse stock split at a ratio

in the range of 1-for-10 to 1-for-100, with the final ratio to be determined by the Company’s Board of Directors (the “Board”),

at any time prior to the one-year anniversary of stockholder approval. On April 9, 2026, the Board approved the Reverse Stock Split at

a ratio of 1-for-40.

As a result of the Reverse Stock Split, every

40 shares of the Company’s issued and outstanding common stock, as well as all shares of common stock held by the Company in treasury,

were automatically combined into one share of common stock, without any change in the par value per share. No fractional shares were issued

in connection with the Reverse Stock Split. Any fractional share of common stock that would otherwise have resulted from the Reverse Stock

Split was rounded up to the nearest whole share. Immediately prior to the effectiveness of the Reverse Stock Split, the Company had 52,639,796

shares of common stock issued and outstanding. Following the Reverse Stock Split, the Company has approximately 1,316,032 shares of common

stock issued and outstanding.

In addition, proportionate adjustments were made

to (i) the per share exercise price and the number of shares issuable upon the exercise of all outstanding stock options and warrants

to purchase shares of common stock, (ii) the number of shares of common stock issuable upon the vesting of outstanding restricted stock

units, and (iii) the number of shares reserved for issuance pursuant to the Company’s equity incentive plans.

The Reverse Stock Split was intended to increase

the per share trading price of the Company’s common stock to better position the Company to attract certain institutional and other

investors and to regain compliance with the minimum bid price requirement for continued listing of the Company’s common stock on

Nasdaq.

In connection with the adoption of the Restated

Certificate, the Board also ratified, pursuant to Section 204 of the General Corporation Law of the State of Delaware, as a defective

corporate act, the Company’s prior one-for-twenty (1:20) reverse stock split effected on September 13, 2024, for which a certificate

of amendment to the Prior Certificate was not filed with the Secretary of State of the State of Delaware at the time of effectiveness.

On April 29, 2026, the Company submitted a Certificate of Validation (the “Certificate of Validation”) with the Secretary of State

of the State of Delaware to validate such prior reverse stock split in accordance with Section 204 of the General Corporation Law of the

State of Delaware. The Restated Certificate restates and integrates in their entirety the provisions of the Prior Certificate, as amended,

including the effects of both the prior 1:20 reverse stock split and the current 1:40 Reverse Stock Split.

Broadridge Corporate Issuer Solutions, LLC, the

Company’s transfer agent, is acting as the exchange agent for the Reverse Stock Split. Registered stockholders holding pre-split

shares of common stock electronically in book-entry form are not required to take any action to receive post-split shares.

The foregoing descriptions of the Restated Certificate

and the Certificate of Validation are qualified in their entirety by reference to the full text of the Restated Certificate and the Certificate

of Validation, copies of which are filed as Exhibits 3.1 and 3.2 hereto, respectively, and are incorporated herein by reference.

Item 8.01 Other Events.

On April 24, 2026, the Company issued a press

release announcing the Reverse Stock Split. A copy of the press release is filed as Exhibit 99.1 hereto and is incorporated herein by

of amendment to the Prior Certificate was not filed with the Secretary of State of the State of Delaware at the time of the intended effectiveness

of such reverse stock split on September 13, 2024. A Certificate of Validation with respect to such defective corporate act has been filed

with the Secretary of State of the State of Delaware concurrently herewith in accordance with Section 204 of the DGCL.

between the Corporation and one or more of its directors, or between the Corporation and any other corporation, firm, association or other

(f) In addition to the powers and authorities

hereinbefore or by statute expressly conferred upon them, the directors are hereby empowered to exercise all such powers and do all such

acts and things as may be exercised or done by the Corporation; subject, nevertheless, to the provisions of the statutes of Delaware,

(g) Whenever a compromise or arrangement

is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any

class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation

CERTIFICATE OF VALIDATION

iSPECIMEN INC.

Pursuant to Section 204 of the

General Corporation Law of the State of Delaware

iSpecimen Inc., a corporation organized and existing

under the laws of the State of Delaware (the “Corporation”), does hereby certify as follows:

1. The

name of the Corporation is iSpecimen Inc. The original certificate of incorporation of the Corporation was filed with the Secretary of

State of the State of Delaware on July 2, 2009.

2. The

defective corporate act being validated by this Certificate of Validation is the 1-for-20 reverse stock split of the Corporation’s

issued and outstanding shares of Common Stock, par value $0.0001 per share (the “1:20 Reverse Stock Split”). Stockholder approval

for a reverse stock split at a ratio in the range of 1-for-10 to 1-for-20 was duly obtained at the annual meeting of stockholders held

on July 19, 2024. The Board of Directors of the Corporation (the “Board”) subsequently approved the 1-for-20 ratio on August

19, 2024, and the 1:20 Reverse Stock Split was intended to become effective at 4:30 p.m. Eastern Time on September 13, 2024, with trading

on a split-adjusted basis commencing on September 16, 2024.

3. The

date of the defective corporate act was September 13, 2024.

4. The

nature of the failure of authorization in respect of the defective corporate act was the failure of the Corporation to file a Certificate

of Amendment to its Fourth Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware as required

to effectuate the 1:20 Reverse Stock Split.

5. The

defective corporate act was ratified by the Board of Directors of the Corporation in accordance with Section 204 of the General Corporation

Law of the State of Delaware (the “DGCL”), by unanimous written consent of the Board dated April 29, 2026.

6. The

1:20 Reverse Stock Split did not require stockholder approval for the purposes of ratification under Section 204 of the DGCL beyond the

stockholder approval previously obtained, which approval was duly obtained at the annual meeting of stockholders held on July 19, 2024,

at which stockholders approved a reverse stock split at a ratio in the range of 1-for-10 to 1-for-20.

7. This

Certificate of Validation shall be effective upon filing with the Secretary of State of the State of Delaware.

of Incorporation to effect a reverse stock split in the range of 1-for-10 to 1-for-100, with the final ratio to be determined by the Board

of Directors (the “Board”). On April 9, 2026, the Board approved a 1-for-40 reverse stock split.

When the reverse stock split becomes effective,

every 40 shares of the Company’s issued and outstanding common stock, as well as all shares held by the Company in treasury, will

automatically be combined into one share of common stock, without any change in the par value per share. In addition, (i) a proportionate

adjustment will be made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding stock options

and warrants to purchase shares of common stock, (ii) a proportionate adjustment will also be made in the number of shares of common

stock issuable upon the vesting of restricted stock units, and (iii) the number of shares reserved for issuance pursuant to the Company’s

stock incentive plans will also be reduced proportionately. Any fraction of a share of common stock that would be created as a result

of the reverse stock split will be rounded up to the nearest whole share at the participant level.

The reverse stock split is intended to increase

the per share trading price of the Company’s common stock to better attract certain institutional and other investors and comply

with the minimum bid price requirement for maintaining the listing of the Company’s common stock on the Nasdaq Capital Market.

Broadridge Corporate Issuer Solutions, LLC (“Broadridge”),

the Company’s transfer agent, will act as the exchange agent for the reverse stock split. Registered stockholders holding pre-split

shares of the common stock electronically in book-entry form are not required to take any action to receive post-split shares. Stockholders

of record will be receiving information from Broadridge about the process for exchanging their pre-split shares for post-split shares.

Forward Looking Statements

This press release may contain forward-looking

statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange

Act of 1934, as amended. Such forward-looking statements are characterized by future or conditional verbs such as “may,” “will,”

“expect,” “intend,” “anticipate,” “believe,” “estimate,” “continue”

or similar words. You should read statements that contain these words carefully because they discuss future expectations and plans, which

contain projections of future results of operations or financial condition or state other forward-looking information.

Forward-looking statements are predictions, projections

and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks

and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this press

release, including but not limited to the risk factors contained in the Company’s filings with the U.S. Securities and Exchange

Commission, which are available for review at www.sec.gov. Forward-looking statements speak only as of the date they are made. New risks

and uncertainties arise over time, and it is not possible for the Company to predict those events or how they may affect the Company.

If a change to the events and circumstances reflected in the Company’s forward-looking statements occurs, the Company’s business,

financial condition and operating results may vary materially from those expressed in the Company’s forward-looking statements.

Readers are cautioned not to put undue reliance

on forward-looking statements, and the Company assumes no obligation and does not intend to update or revise these forward-looking statements,

whether as a result of new information, future events or otherwise.
