Intrusion Inc.

Reports Second Quarter 2026 Results

Sequential revenue growth and the acquisition

of VigilAigent enhance revenue quality and visibility while accelerating the Company's path to profitability

PLANO, Texas, August 11, 2026 (ACCESSWIRE)

-- Intrusion Inc. (NASDAQ: INTZ) (“Intrusion” or the “Company”), a provider of AI-powered cyberattack prevention,

threat intelligence, and managed cybersecurity solutions, announced today financial results for the second quarter ended June 30, 2026.

Recent Financial & Business Highlights:

· Achieved sequential revenue growth of 64% during

the second quarter of 2026.

· Completed the acquisition of VigilAigent to create

an AI-native cybersecurity platform and improve the Company’s top line by adding approximately $3.5 million in annual recurring

revenue from multi-year contracts.

· Hosted a Technology & Innovation Day highlighting

the combined capabilities power of Intrusion and VigilAigent’s technologies.

· Signed a $4 million annual contract to deliver

cyber threat intelligence and critical infrastructure protection to the state of Texas.

VigilAigent Acquisition Integration Highlights

Since Closing:

· Advanced integration of the combined organizations

while maintaining customer support and service continuity.

· Identified more than $3 million of potential

annualized operating cost synergies.

· Continued commercial momentum through customer

renewals, new business, and partner engagement.

· Expanded the Company's strategic foundation with

enhanced Ai capabilities, managed security expertise, and a broader commercial platform.

“The second quarter was a pivotal one for

Intrusion. We returned to sequential revenue growth and restored the revenue run rate achieved prior to the funding delay associated with

the Department of War contract. We also made significant progress in positioning our business for future growth, as demonstrated by our

recent acquisition of VigilAigent,” said Tony Scott, President & Chief Executive Officer of Intrusion. “The addition of

VigilAigent will be immediately accretive to our top line results by adding approximately $3.5 million of annual recurring revenue over

the upcoming quarters from a diversified base of multi-year customer contracts. We believe that integrating VigilAigent's technology with

Intrusion's will create a unified platform that expands our ability to serve larger enterprise customers, strengthens our competitive

position, and drives strategic customer acquisition and long-term organic growth.”

Mr. Scott concluded, “As we look toward

the second half of fiscal 2026, we are confident that we will begin to see a steady improvement in our financial results. The quality

and visibility of our revenue has already improved, and we expect this trend to continue as we further expand our sales pipeline. This

gives us great confidence that we remain on track to transition Intrusion to profitability in fiscal year 2027 and create value for our

shareholders.”

Second Quarter Financial Results

Revenue for the second quarter of 2026 was $1.5

million, representing an increase of 64% on a sequential basis and a decrease of 22% compared to the prior year period. Performance continued

to be impacted by delays in the award of a key U.S. government contract. The Company remains optimistic that a meaningful portion of the

associated revenue will be realized in future periods subject to final award timing and funding approvals.

The gross profit margin was 66% for the second

quarter of 2026, compared to 74% for the first quarter of 2026 and 76% for the prior year period. Gross margin varies based on product

mix.

Operating expense for the second quarter of 2026

was $3.4 million, a decrease of $0.8 million sequentially and a decrease of less than $0.1 million compared to the second quarter of 2025.

Net loss for the second quarter of 2026 was $2.6

million, or $(0.13) per share, compared to a net loss of $2.0 million, or $(0.10) per share, in the second quarter of 2025.

As of June 30, 2026, cash and cash equivalents

were $0.2 million.
