7 terms

nasdaq listing rule 5635(c)(4) regulatory

"in accordance with Nasdaq Listing Rule 5635(c)(4) (the “Inducement Grant”)."

NASDAQ Listing Rule 5635(c)(4) is a rule that requires a company to get approval from its shareholders before selling a large amount of its shares, usually over 20%. This helps protect investors by making sure the company doesn't flood the market with new shares without their say, which could lower the stock's value.

non-qualified stock options financial

"granted non-qualified stock options to purchase an aggregate of 235,700 shares"

Non-qualified stock options are a type of employee benefit that gives individuals the right to buy company shares at a set price, usually lower than the market value, within a certain period. Unlike other options that may have special tax advantages, these options are taxed as income when exercised, which can affect how much money the employee or investor ultimately gains. They are important because they can influence company compensation strategies and impact the financial outcomes for employees and investors.

restricted stock units financial

"an aggregate of 33,450 restricted stock units of the Company’s common stock"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

exercise price financial

"an exercise price per share of $23.23, which is equal to the closing price"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

vesting financial

"The Stock Options will vest over a four-year period, with 25% of the shares vesting"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

inducement grant financial

"as the “Inducement Grant”). The Stock Options have a ten-year term"

An inducement grant is a stock-based reward given to a new hire—often options or restricted shares—used as a recruiting “signing bonus” to encourage someone to join a company and stay long enough to add value. Investors care because these grants can dilute existing shareholdings, change executive incentives and increase reported compensation costs, so they signal both management priorities and potential impacts on shareholder value.

inducement plan financial

"subject to, the terms and conditions of the Company’s 2026 Inducement Plan"

An inducement plan is a program a company creates to encourage employees or new hires to stay or join by offering special benefits or rewards. It’s like a company giving extra bonuses or perks to persuade someone to choose their job over others, helping the company attract and keep talented workers.

WALTHAM, Mass., March 16, 2026 (GLOBE NEWSWIRE) -- Zenas BioPharma, Inc. (“Zenas” or the “Company”) (Nasdaq: ZBIO), a clinical-stage global biopharmaceutical company committed to being a leader in the development and commercialization of transformative therapies for patients living with autoimmune diseases, today announced that on March 16, 2026 (the “Grant Date”), the Compensation Committee of the Company’s Board of Directors granted non-qualified stock options to purchase an aggregate of 235,700 shares of the Company’s common stock (“Stock Options”) and an aggregate of 33,450 restricted stock units of the Company’s common stock (“RSUs”) to newly hired employees of the Company as an inducement material to such employees’ entry into employment with the Company, in accordance with Nasdaq Listing Rule 5635(c)(4) (the “Inducement Grant”).

The Stock Options have a ten-year term and an exercise price per share of $23.23, which is equal to the closing price of Zenas’ common stock on the Grant Date. The Stock Options will vest over a four-year period, with 25% of the shares vesting on the one-year anniversary of each of the employees’ first day of employment with the Company, and thereafter the remainder of the option will vest in 36 equal monthly installments. The RSUs will vest in four (4) equal installments over a four-year period, with vesting as to twenty-five percent (25%) of the RSUs subject to the award on each of March 15, 2027, March 15, 2028 March 15, 2029 and March 15, 2030. Inducement Grants are subject to the employees’ continued service with Zenas through the applicable vesting dates. The Inducement Grants were granted pursuant to, and are subject to, the terms and conditions of the Company’s 2026 Inducement Plan and the applicable award agreement.

About Zenas BioPharma, Inc.

Zenas is a clinical-stage global biopharmaceutical company committed to becoming a leader in the development and commercialization of transformative therapies for patients living with autoimmune diseases. Our core business strategy combines our experienced leadership team with a disciplined product candidate acquisition approach to identify, acquire and develop product candidates globally that we believe can provide superior clinical benefits to patients living with autoimmune diseases. Zenas is advancing two late-stage, potential franchise molecules, obexelimab and orelabrutinib. Obexelimab, Zenas’ lead product candidate, is a bifunctional monoclonal antibody designed to bind both CD19 and FcγRIIb, which are broadly present across B cell lineage, to inhibit the activity of cells that are implicated in many autoimmune diseases without depleting them. We believe that obexelimab’s unique mechanism of action and self-administered, subcutaneous injection regimen may broadly and effectively address the pathogenic role of B cell lineage in chronic autoimmune disease. Orelabrutinib is a potentially best-in-class, highly selective CNS-penetrant, oral, small molecule BTK inhibitor. Orelabrutinib’s mechanism of action targets pathogenic B cells not only in the periphery but also within the CNS. Additionally, it directly modulates macrophages and microglial cells in the CNS, with the potential to address compartmentalized inflammation and disease progression in MS. Zenas’ earlier stage programs include ZB021, a preclinical, potentially best-in-class, oral, IL-17AA/AF inhibitor, and ZB022, a preclinical, potentially best-in-class, oral, brain-penetrant, TYK2 inhibitor.
