Enterprise decision intelligence company adopts the name of its methodology as it builds vertical software one industry at a time

SEMINOLE, Okla. — September 9, 2026 — Growth Stalk Holdings Corp. (OTC: GSTK) today announced that its corporate name change to Cyphaira Corp. has been approved and that its common stock will begin trading on OTC Markets under the new symbol “CYPA” at the open of trading on September 10, 2026. The stock continues to trade as “GSTK” through the close of trading on September 9, 2026. The CUSIP number of the common stock is unchanged.

The name change does not affect the company’s shares outstanding, the rights of shareholders, or the company’s reporting obligations. Shareholders are not required to take any action; brokerage accounts will reflect the new name and symbol automatically. Filings made before the change remain under the Growth Stalk Holdings name.

Cyphaira Corp. is developing business decision-intelligence software one vertical at a time, using one methodology — Understand, Decide, Act — applied by operators who do the work. Its first product, SolvixLMS, is an operating system for regulated manufacturing environments in alpha testing; it is not commercially available and has generated no revenue. Source-verified at 583,041 first-party source lines as of August 24, 2026.

“Businesses don’t need more information. They need intelligence,” said Joseph Babiak, Chief Executive Officer. “Every system a company runs holds a piece of reality, and none of them understands the business. We build software that does, one industry at a time, with the people who do the work. The new name is the method.”

The company labels every material claim it makes as current, verified with a basis date, planned, or vision, and will report the same six measures to shareholders every quarter, including shortfalls. The first shareholder letter follows the name change.
