Material Definitive Agreement regulatory
"Item 1.01 Entry into a Material Definitive Agreement. Warrant"
A material definitive agreement is a legally binding contract that creates major, long‑term obligations or rights for a company, such as loans, asset sales, mergers, or supplier deals. Think of it like a mortgage or lease for a business: it can change future cash flow, risk and control, so investors watch these agreements closely because they can materially affect a company’s value, financial health and stock price.
cashless exercise financial
"at the Warrantholder's election by cash payment or cashless exercise"
A cashless exercise is a way for an option holder to convert stock options into actual shares without paying the purchase price in cash; instead they immediately give up a portion of the newly issued shares to cover the cost and any withholding taxes. Investors care because this process increases the number of shares available and can slightly dilute existing holdings, while also signaling how insiders or employees are realizing compensation without needing cash — similar to paying for a purchase by handing over part of what you just bought.
Section 4(a)(2) of the Securities Act of 1933 regulatory
"in reliance on the exemption from registration pursuant to Section 4(a)(2) of the Securities Act of 1933"
change of control financial
"accelerated vesting of certain Warrant Shares upon the occurrence of specified change of control transactions"
A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.

What warrant did A10 Networks (ATEN) grant to Microsoft?
A10 Networks granted Microsoft a warrant to purchase up to 800,000 shares of A10 common stock at an exercise price of $0.01 per share. Vesting depends on Microsoft and its affiliates meeting specified purchase thresholds for A10 products and services over defined measurement periods.
How does the vesting of the A10 Networks (ATEN) warrant for Microsoft work?
The warrant can vest in two tranches of up to 400,000 shares each, tied to Microsoft’s purchase levels. Vesting is measured over periods ending June 30, 2027 and June 30, 2028, and any tranche for which the purchase threshold is not achieved will expire unvested.

Vested shares from the first tranche are exercisable after January 1, 2028, and from the second tranche after January 1, 2029. The warrant remains exercisable until August 3, 2036, after which any unexercised portion will lapse according to its stated expiration.
What exercise methods are available under the A10 Networks (ATEN) warrant granted to Microsoft?
Microsoft may exercise the warrant, once vested and exercisable, either by paying cash or through cashless exercise. This flexibility allows the holder to acquire shares without necessarily making a full cash payment, subject to the warrant’s detailed terms and conditions.
Under what securities law exemption was the A10 Networks (ATEN) warrant to Microsoft issued?
The warrant, and the shares issuable upon its exercise, were issued in reliance on Section 4(a)(2) of the Securities Act of 1933. This exemption covers certain private offerings and means the warrant and underlying shares were not registered under the Securities Act.
Does the A10 Networks (ATEN) warrant to Microsoft include change of control protections?
