Opexa Therapeutics Reminds Shareholders That Rights Offering Expires on April 8, 2022 at 5:00 PM ET


THE WOODLANDS, Texas--(BUSINESS WIRE)-- Opexa Therapeutics, Inc. (NASDAQ:OPXA), a company developing personalized immunotherapies for autoimmune disorders, including multiple sclerosis (MS) and neuromyelitis optica (NMO), provides a reminder to shareholders that its previously announced rights offering will remain open until 5:00 PM Eastern Time on Wednesday, April 8, 2022, unless extended. Rights holders will need to exercise their subscription rights prior to that date and time.

If exercising subscription rights through a broker, dealer, bank or other nominee, rights holders should promptly contact their nominee and submit subscription documents and payment for the units subscribed for in accordance with the instructions and within the time period provided by such nominee. The broker, dealer, bank or other nominee may establish a deadline before April 8th by which instructions to exercise subscription rights, along with the required subscription payment, must be received.

All record holders of rights certificates that wish to participate in the rights offering must deliver a properly completed and signed rights certificate, together with payment of the subscription price for both basic subscription rights and any oversubscription privilege election, to the Subscription Agent, to be received before 5:00 p.m., Eastern Time, on April 8, 2022. The Subscription Agent is:

Continental Stock Transfer & Trust Company
17 Battery Place—8th Floor
New York, NY 10004
Attn: Corporate Actions Department
Telephone: (917) 262-2378

The non-transferable subscription rights entitle holders of Opexa common stock and holders of outstanding Series L warrants as of March 13, 2022 (the record date) to purchase units, composed of one share of common stock and a warrant to purchase common stock, at the subscription price of $0.55 per unit. Holders who fully exercise their basic subscription rights may oversubscribe (on a pro rata basis and subject to ownership limitations) for any remaining unsubscribed units. The three-year warrant will entitle the holder to purchase one share of common stock at an exercise price of (i) $0.50 per share from the date of issuance through June 30, 2016 and (ii) $1.50 per share from July 1, 2016 through the warrant expiration date. Opexa has applied to list the warrants on NASDAQ, although there is no assurance that a sufficient number of subscription rights will be exercised so that the warrants will meet the minimum listing criteria to be accepted for listing on NASDAQ. The warrants will be redeemable if Opexa’s common stock closes above $2.50 per share for 10 consecutive trading days.

Opexa has engaged Maxim Group LLC as lead dealer-manager and National Securities Corporation as co-dealer-manager for the rights offering.

About Opexa

Opexa is a biopharmaceutical company developing a personalized immunotherapy with the potential to treat major illnesses, including multiple sclerosis (MS) as well as other autoimmune diseases such as neuromyelitis optica (NMO). These therapies are based on Opexa’s proprietary T-cell technology. The Company’s leading therapy candidate, Tcelna®, is a personalized T-cell immunotherapy that is in a Phase IIb clinical development program (the Abili-T trial) for the treatment of secondary progressive MS. Tcelna is derived from T-cells isolated from the patient’s peripheral blood, expanded ex vivo, and reintroduced into the patients via subcutaneous injections. This process triggers a potent immune response against specific subsets of autoreactive T-cells known to attack myelin.
