American: AMBO), an innovator in AI-powered phygital (physical + digital) intelligence solutions for education, enterprise collaboration,

and live events, today announced its unaudited financial and operating results for the six-month period and three-month period ended

June 30, 2026.

First

Half and Second Quarter 2026 and Recent Financial and Operating Highlights

● Net

revenues for the first half of 2026 increased 2.0% year over year to $5.2 million, led by

growth in educational programs and services.

● Gross

profit margin for the first half of 2026 expanded to 55.8% from 54.9% in the first half of

2025.

● Research

and development expenses increased to $0.4 million for the first half of 2026 from $0.2 million

in the first half of 2025, reflecting continued investment in the HybriU platform.

● General

and administrative expenses decreased to $1.4 million for the first half of 2026 from $1.6

million in the first half of 2025, reflecting continued cost control measures.

● Ambow

received federal registration of the HybriU trademark on July 28, 2026.

● Subsequent

to quarter end, Ambow launched the HybriU AI Adaptive Course Generation Platform, the Company’s

third HybriU product launch of 2026.

● Subsequent

to quarter end, Ambow announced free access for 1,000 students to an AI + Design Hybrid Micro-Credential

Program at NewSchool of Architecture & Design, delivering on the Company’s White

House Pledge to America’s Youth commitment.

“Our

first half results reflect steady progress in the educational programs and services business alongside continued investment in the HybriU

platform,” said Dr. Jin Huang, Chief Executive Officer and Chair of the Board of Ambow Education Holding Ltd. “We

expanded gross margin, maintained disciplined cost control, and continued to build the product foundation that we believe positions HybriU

for long-term growth in Knowledge Intelligence.”

Second

Quarter 2026 Financial Results

Net

revenues for the second quarter of 2026 decreased by 14.3% to $2.4 million from $2.8 million for the same period of 2025. The decrease

was primarily attributable to the decline in net revenues from HybriU licensing and sales, partially offset by growth in educational

programs and services.

Gross

profit for the second quarter of 2026 decreased by 20.0% to $1.2 million from $1.5 million for the same period of 2025. Gross profit

margin was 50.0% for the second quarter of 2026, compared with 53.6% for the second quarter of 2025.

Operating

expenses for the second quarter of 2026 increased by 27.3% to $1.4 million from $1.1 million for the same period of 2025. The increase

primarily reflected higher selling and marketing and research and development expenses, together with a $0.2 million impairment loss

on construction in progress, partially offset by lower general and administrative expenses.

Operating

loss for the second quarter of 2026 was $0.1 million, compared with operating income of $0.3 million for the same period of 2025.

Net

loss attributable to ordinary shareholders for the second quarter of 2026 was $0.1 million, or $0.05 per basic and diluted ADS, compared

with net income of $1.8 million, or $0.62 per basic and diluted ADS, for the same period of 2025. Net income for the second quarter of

2025 included a one-time gain on lease settlement of $1.5 million.

First

Half 2026 Financial Results

Net

revenues for the first half of 2026 increased by 2.0% to $5.2 million from $5.1 million for the same period of 2025. The increase

was primarily due to net revenues generated by educational programs and services.

Gross

profit for the first half of 2026 increased by 3.6% to $2.9 million from $2.8 million for the same period of 2025. Gross profit margin

was 55.8% for the first half of 2026, compared with 54.9% for the first half of 2025.

Operating

expenses for the first half of 2026 increased by 13.0% to $2.6 million from $2.3 million for the same period of 2025.

Operating

income for the first half of 2026 was $0.3 million, compared with $0.5 million for the same period of 2025.

Net

income attributable to ordinary shareholders for the first half of 2026 was $0.3 million, or $0.10 per basic and diluted ADS, compared

with $1.9 million, or $0.66 per basic and diluted ADS, for the same period of 2025. Net income for the first half of 2025 included a

one-time gain on lease settlement of $1.5 million.

Balance

Sheet and Liquidity

of June 30, 2026, Ambow maintained cash resources of $7.2 million, comprising cash and cash equivalents of $4.5 million and restricted

cash of $2.7 million. As of June 30, 2026, the Company’s consolidated current assets exceeded its consolidated current liabilities

The

Company’s financial and operating results for the first half and second quarter of 2026 are also available in its Quarterly Report

on Form 10-Q, filed with the U.S. Securities and Exchange Commission (the “SEC”) at www.sec.gov.
