MIDLAND, Texas, August 10, 2026 – AST SpaceMobile, Inc. (“AST SpaceMobile”) (NASDAQ: ASTS), the company building the first and only space-based cellular broadband network accessible directly by everyday smartphones, and designed for both commercial and government applications, is providing its business update and results for the second quarter ended June 30, 2026.

“AST SpaceMobile's differentiated technology platform and deep intellectual property portfolio, partner-first mobile network operator strategy, vertically integrated manufacturing capabilities, and comprehensive spectrum strategy are foundational to the space-based cellular broadband market we invented,” commented Abel Avellan, AST SpaceMobile’s Chairman and Chief Executive Officer. “With the largest phased arrays ever deployed in low Earth orbit and a native cellular architecture designed to work directly with standard, unmodified smartphones, we believe we are uniquely positioned to deliver scalable direct-to-device connectivity for both commercial and government customers around the world.”

“Following the recent orbital launch of BlueBirds 11, 12, and 13, our space-based cellular broadband network has now grown to 13 spacecraft in orbit, each the largest ever in low Earth orbit, with approximately 20,000 square feet of combined aperture hardware deployed,” continued Avellan. “As we get ready to ship BlueBirds 14, 15, and 16 and continue expanding our constellation with production ongoing through BlueBird 46, we are preparing to initiate beta services with select strategic partners.”

“AST SpaceMobile is positioned at the forefront of large, diverse, and rapidly expanding market opportunity as the direct-to-device cellular broadband pioneer,” added Avellan. “Beyond addressing the connectivity needs of billions of mobile subscribers, we are pursuing a broad range of mission critical applications, including government communications and non-communications, radar, emergency response, Internet of Things, AI edge compute and other advanced connectivity solutions. Our growing commercial and government programs,

expansive spectrum portfolio, and fortified balance sheet provide us with the flexibility to capture opportunities across an expanding total addressable market. We are continuing to scale our network, advance vertical integration, and secure additional access to orbit to take advantage of the growing number of opportunities in front of us.”

Second Quarter 2026 Financial Highlights

(1) See “Non-GAAP Financial Measures” below for additional information. See reconciliation of Adjusted operating expenses to Total operating expenses; Adjusted cost of revenues to Cost of revenues; Adjusted engineering services costs to Engineering services costs; Adjusted general

and administrative costs to General and administrative costs; and Adjusted operating expenses, excluding Adjusted cost of revenues to Total operating expenses in the tables accompanying this press release.

Non-GAAP Financial Measures

We refer to certain non-GAAP financial measures in this press release, including Adjusted operating expenses; Adjusted cost of revenues; Adjusted engineering services costs; Adjusted general and administrative costs; and Adjusted operating expenses, excluding Adjusted cost of revenues. We believe these non-GAAP financial measures are useful measures across time in evaluating our operating performance as we use these measures to manage the business, including in preparing our annual operating budget and financial projections. These non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP, and therefore have limits in their usefulness to investors. Because of the non-standardized definitions, these measures may not be comparable to the calculation of similar measures of other companies and are presented solely to provide investors with useful information to more fully understand how management assesses performance. These measures are not, and should not be viewed as, a substitute for their most directly comparable GAAP measures. Reconciliation of non-GAAP financial measures and the most directly comparable GAAP financial measures are included in the tables accompanying this press release.

RECONCILIATION OF GAAP REPORTED TO NON-GAAP ADJUSTED MEASURES (UNAUDITED)

(Dollars in thousands)

Adjusted operating expenses; Adjusted cost of revenues; Adjusted engineering services costs; Adjusted general and administrative costs; and Adjusted operating expenses, excluding Adjusted cost of revenues are alternative financial measures used by management to evaluate our operating performance as a supplement to our most directly comparable U.S. GAAP financial measure. We define Adjusted operating expenses as Total operating expenses adjusted to exclude amounts of stock-based compensation expense, loss on involuntary conversion, and depreciation and amortization expense. We define Adjusted cost of revenues, Adjusted engineering services costs, and Adjusted general and administrative costs, as cost of revenues, engineering services costs, and general and administrative costs, respectively, adjusted to exclude stock-based compensation expenses. We define Adjusted operating expenses, excluding Adjusted cost of revenues as Total operating expenses adjusted to exclude amounts of stock-based compensation expense, loss on involuntary conversion, depreciation and amortization expense, and Adjusted cost of revenues.

We believe Adjusted operating expenses; Adjusted cost of revenues; Adjusted engineering services costs; Adjusted general and administrative costs; and Adjusted operating expenses, excluding Adjusted cost of revenues are useful measures across time in evaluating our operating performance as we use these measures to manage the business, including in preparing our annual operating budget and financial projections. Adjusted operating expenses; Adjusted cost of revenues; Adjusted engineering services costs; Adjusted general and administrative costs; and Adjusted operating expenses, excluding Adjusted cost of revenues are non-GAAP financial measures that have no standardized meaning prescribed by U.S. GAAP, and therefore have limits in their usefulness to investors. Because of the non-standardized definitions, these measures may not be comparable to the calculation of similar measures of other companies and are presented solely to provide investors with useful information to more fully understand how management assesses performance. These measures are not, and should not be viewed as, a substitute for their most directly comparable GAAP measure of Total operating expenses, Cost of revenues, Engineering services costs, and General and administrative costs.
