   First Quarter of Fiscal 2018 and Reiterates Full Year Guidance

Fremont, CA (September 28, 2017) - Aehr Test Systems (NASDAQ: AEHR),
a worldwide supplier of semiconductor test and burn-in equipment, today
announced financial results for its first quarter of fiscal 2018 ended
August 31, 2017.

Fiscal First Quarter Financial Results:

- Net sales were $7.0 million, up 31% from $5.3 million in the first
  quarter of fiscal 2017.

- GAAP net income was $10,000, or $0.00 per diluted share, compared
  to a GAAP net loss of $755,000, or $0.06 per diluted share, in the
  first quarter of fiscal 2017.

- Non-GAAP net income was $226,000, or $0.01 per diluted share,
  compared to a non-GAAP net loss of $436,000, or $0.03 per diluted
  share, in the first quarter of fiscal 2017.

- Backlog as of August 31, 2017 was $15.2 million.


An explanation of the use of non-GAAP financial information and a
reconciliation of the non-GAAP financial measures to the most directly
comparable GAAP financial measures can be found in the accompanying
tables.

First Quarter and Recent Business Highlights:

- Announced today that it received follow-on orders totaling $2.7 million
 from a subcontractor of its initial lead FOX-XPTM Test and Burn-in
 System customer. The orders include a partially populated FOX-XP system,
 multiple DiePak(R) carriers for their next generation devices, and
 multiple DiePak loader/unloaders to increase their current production
 capacity.

- Announced earlier this month a $900,000 order received in the first
  quarter from its second lead FOX-XP customer to provide additional
  testing capability and power handling capacity to test and burn-in
  new silicon photonics that will go into production next year.

- Announced in late August its first volume production order exceeding
  $3.0 million for multiple Advanced Burn-in and Test System (ABTSTM)
  thermal chambers from an OEM customer for a high-volume application.

- Announced during the quarter a follow-on order exceeding $1.3 million
  for multiple WaferPakTM contactors for its FOX-1 wafer level test
  systems for flash memory testing.

- Announced during the quarter a follow-on order exceeding $3.8 million
  for multiple ABTS test and burn-in systems from a leading
  multi-national manufacturer of advanced logic integrated circuits
  (ICs) for automotive devices.

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

"We are off to a great start for fiscal 2018. We finished the first
quarter with revenue of $7.0 million, GAAP net income of a little over
break-even, non-GAAP net income of $226,000, which excludes non-cash
related stock-based compensation expense, and a backlog of $15.2 million.
With today's order announcement for $2.7 million for our FOX-XP Test
and Burn-in Solution products,this adds up to approximately $18 million
in backlog early in our second quarter. We are very pleased with the
installations of our new FOX-XP Multi-Wafer and Singulated Die/Module
Test and Burn-in systems at our two lead customers, and both have
purchased follow-on capacity and capability.

"Earlier this month, we received an order from one of these lead customers
to provide additional testing capability and power handling capacity
to their previously delivered FOX-XP system in order to test and burn-in
new silicon photonics devices that will go into production next year.
And today we announced that we received follow-on orders from a
subcontractor of our initial lead FOX-XP Test and Burn-in System customer.
The orders include a partially populated FOX-XP system, multiple DiePak
carriers for their next generation devices, and multiple DiePak
loader/unloaders to increase their current production capacity. These
newest orders continue to expand our production presence with this
customer for multiple generations of devices. In addition, we have
ongoing discussions with several additional companies about our new
FOX-XP platform and we are optimistic about the prospects with these
prospective new customers.

"We continue to maintain our confidence in our growth forecast for the
fiscal year ahead. We reiterate our previously provided financial
guidance for the fiscal year ending May 31, 2018 of full year total
revenue growth of at least 50% over fiscal 2017 and to be profitable
for the year.

"We believe Aehr Test is very well positioned to capitalize on the market
opportunities for our new products that address the needs of our
customers to ensure reliability of their semiconductors, integrated
modules, and systems where safety, security, and assurance of user
confidence are absolutely critical."

______________________________________________________________________


Non-GAAP net income (loss) is a non-GAAP measure and should not be considered
a replacement for GAAP results.  Non-GAAP net income (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 income.  This
limitation is best addressed by using this measure in combination with net
income (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.
