  received final system acceptance at the customers' sites.

- Received a $3.7 million follow-on production order for a FOX-XP test
  and burn-in system configured with Aehr Test's new highly parallel
  singulated die/module test interface technology and a set of
  proprietary DiePak(R) carriers. The order was from a subcontractor
  to Aehr Test's lead customer for the FOX-XP Test and Burn-in System.

- Announced a follow-on order exceeding $1.9 million for multiple
  Advanced Burn-in and Test (ABTSTM) systems from a leading
  multi-national semiconductor supplier of automotive devices.

- Received an initial production order of $850,000 from an OEM customer
  for multiple proprietary ABTS thermal chambers following completion
  and acceptance of an initial ABTS chamber order delivered to this
  customer earlier in the fiscal year.

- Completed successful public offering of approximately 4.4 million
  shares of common stock at a price to the public of $3.90 per share,
  including the underwriter's exercise of its option to purchase
  approximately 577,000 additional shares to cover over-allotments.


Gayn Erickson, President and CEO of Aehr Test Systems, commented:

"We exceeded our revenue guidance of $6 million for the fourth quarter,
with total quarterly revenue of $6.7 million, and finished our fiscal
2017 with total revenue of $18.9 million, up 30% from the prior year.
We are encouraged by the demand for our new FOX wafer-level and singulated
die/module test and burn-in systems as well as our ABTS packaged part
test and burn-in systems. We announced several sizable orders during the
quarter which brought our total orders for the fiscal year to $26.4 million.

"During the quarter, we shipped our new FOX-XP Multi-Wafer and Singulated
Die/Module Test and Burn-in Systems to our two lead customers. Each of
these systems was shipped and installed during the quarter and has since
been accepted at the customers' sites. We believe our solutions are the
most robust and accurate wafer level and module level test and burn-in
systems on the market, delivering substantially more test functionality
and parallelism than any other competitive product available.

"With our reported backlog of $12.7 million as of May 31, 2017, along
with the recently reported bookings of over $3.8 million for our ABTS
systems, we effectively head into fiscal 2018 with over $16.5 million
in booked orders. With the market opportunities we see for our FOX-XP
products, and a strong backlog of orders, we are very optimistic about
our growth potential for fiscal 2018."


Fiscal 2018 Financial Guidance:

For the fiscal year ending May 31, 2018, we expect full year total
revenue growth to exceed 50% over fiscal 2017 and to be profitable for
the year.

About Aehr Test Systems
Headquartered in Fremont, California, Aehr Test Systems is a worldwide
provider of test systems for burning-in and testing logic and memory
integrated circuits and has an installed base of more than 2,500 systems
worldwide. Increased quality and reliability needs of the Automotive
and Mobility integrated circuit markets are driving additional test
requirements, capacity needs and opportunities for Aehr Test products
in package and wafer level test. Aehr Test has developed and introduced
several innovative products, including the ABTS and FOX families of
test and burn-in systems, WaferPak contactors, and DiePak carriers. The
ABTS systems are used in production and qualification testing of packaged
parts for both low-power and high-power logic as well as memory devices.
The FOX family of systems includes single and multi-wafer full wafer contact
test and burn-in systems used for burn-in and functional test of complex
devices, such as leading-edge memories, digital signal processors,
microprocessors, microcontrollers and systems-on-a-chip. The WaferPak
contactor contains a unique full wafer probe card capable of testing wafers
up to 300mm that enables IC manufacturers to perform test and burn-in of
full wafers on Aehr Test FOX systems. The DiePak carrier is a reusable,
temporary package that enables IC manufacturers to perform cost-effective
final test and burn-in of both bare die and modules. For more information,

______________________________________________________________________


Non-GAAP net loss is a non-GAAP measure and should not be considered a
replacement for GAAP results.  Non-GAAP net loss is a financial measure the
Company uses to evaluate the underlying results and operating performance
of the business.  The limitation of this measure is that it excludes items
that impact the Company's current period net loss.  This limitation is best
addressed by using this measure in combination with net loss (the most directly
comparable GAAP financial measure).  These measures are not in accordance
with GAAP and may differ from non-GAAP methods of accounting and reporting
used by other companies.

We believe these measures enhance investors' ability to review the company's
business from the same perspective as the company's management and facilitate
comparisons of this period's results with prior periods.
