    Advanced Energy Industries, Inc., a Delaware corporation (the "Company"),
hereby amends its Current Report on Form 8-K dated August 15, 1997 (filed August
19, 1997) (the "Initial Report"), to read in its entirety as follows. Financial
information omitted from the Initial Report pursuant to paragraphs (a)(4) and
(b)(2) of Item 7 of Form 8-K is included herein.
 
ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.
 
    On August 15, 1997, the Company acquired Tower Electronics, Inc. ("Tower"),
pursuant to a Share Purchase Agreement dated as of August 11, 1997, among the
Company, Roger C. Hertel, an individual and the former sole shareholder of Tower
("Seller"), and Tower. Tower designs and manufactures custom, high performance
switchmode power supplies that are used principally in the telecommunications,
medical and non-impact printing industries. Tower's principal customers include
U.S. Robotics (recently acquired by 3Com Corporation) and its contract
manufacturer, VideoJet Systems International, Inc., Medtronic and Intermedics.
Tower, together with its subsidiary (the "Tower Companies"), had revenues of
$13.4 million for its fiscal year ended September 30, 1996. The purchase price
consisted of $14.5 million in cash and a promissory note to Seller in the
original principal amount of $1.5 million, which were delivered by the Company
at closing, and an earn out provision, pursuant to which Seller will be entitled
to additional consideration for his shares if Tower's sales achieve certain
levels in 1998. The promissory note matures in August 1998 and is non-interest
bearing. $12 million of the cash payment made at closing was funded by a term
loan from Silicon Valley Bank and Bank of Hawaii, pursuant to a Loan and
Security Agreement dated August 15, 1997. The acquisition will be accounted for
using the purchase method of accounting. For additional information with respect
to the Tower acquisition, see the Unaudited Pro Forma Condensed Consolidated
Financial Statements set forth in Item 7 of this Form 8-K/A.
 
    The Company intends to continue Tower's manufacturing operations out of
Tower's existing facilities, which consist of approximately 21,000 square feet
of leased space in Fridley, Minnesota. The Company also has retained all of
Tower's approximately 85 full-time employees.
 
ITEM 7. FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.
 
    Historical consolidated financial statements with respect to the Tower
Companies are provided as of and for the fiscal year ended September 30, 1996
(audited) and the nine-month periods ended June 30, 1997 and 1996 (unaudited).
 
    Pro forma results of operations reflecting the Tower acquisition, are based
on the Company's and the Tower Companies' consolidated operating results for the
year ended December 31, 1996 and for the six months ended June 30, 1997 and on
certain assumptions and estimates, as set forth in the Unaudited Pro Forma
Condensed Consolidated Financial Statements and the notes thereto. The pro forma
condensed consolidated statements of operations for the year ended December 31,
1996 and for the six months ended June 30, 1997 have been prepared as if the
Tower acquisition had occurred on January 1, 1996. Such pro forma information is
not necessarily indicative of the operating results that actually would have
been achieved if the Tower acquisition had occurred on such date. In addition,
operating results of the Tower Companies for the six months ended June 30, 1997
are not indicative of the results that may be expected for the entire year
ending December 31, 1997 or any future period. Tower has experienced, and the
Company expects that Tower will continue to experience, significant fluctuations
in its quarterly operating results. Because Tower, like the Company, is a
supplier of subsystems to original equipment manufacturers, Tower's operating
results are affected by a number of factors, including economic conditions in
the industries in which Tower's customers operate, timing and receipt of orders
from major customers, customer cancellations and shipment delays, changes in
customers' inventory management practices, pricing competition and manufacturing
efficiencies. Specifically, approximately 74% of the Tower Companies' revenues
for the nine months ended June 30, 1997 were attributable to Tower's sales to
U.S. Robotics and its contract manufacturer. Tower's sales to U.S. Robotics and
its contract manufacturer in the quarters ending September 30, 1997 and December
31, 1997 are expected to be significantly lower than such sales in the first two
quarters of 1997. As a result, Tower's total sales are expected to be
significantly lower in the six months ending December 31, 1997 than in the six
months ended June 30, 1997. The Company expects that such decrease in sales also
may adversely affect Tower's gross margins during such period, principally
<PAGE>
due to reduced absorption of manufacturing overhead costs. However, the Company
does not believe that Tower's expected operating results through the end of 1997
will have a material adverse effect on the Company's consolidated results of
operations during such period.
 
    The foregoing statements as to the Company's expectations with respect to
Tower's operating results, and the effects of such results, are forward-looking
statements (within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended)
that involve risks and uncertainties. Tower's and the Company's actual results
may differ materially from those discussed in the forward-looking statements.
Factors that might cause such differences include, but are not limited to, those
set forth above and in the prospectus included in the Company's registration
statement on Form S-3 (File No. 333-34039), as amended.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholder of
Tower Electronics, Inc.:
 
    We have audited the accompanying consolidated balance sheet of Tower
Electronics, Inc. and Subsidiary as of September 30, 1996, and the related
consolidated statements of operations, stockholder's equity and cash flows for
the year then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Tower
Electronics, Inc. and Subsidiary as of September 30, 1996, and the consolidated
results of their operations and their cash flows for the year then ended in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BUSINESS DESCRIPTION:
 
    Tower Electronics, Inc. is engaged in the business of developing,
manufacturing, marketing, distributing and servicing certain power supplies,
including custom, high-performance, switching power supplies and AC/DC
converters used in the electronics and medical industries. A significant portion
of the Company's sales are concentrated in several customers (see Note 7). The
Company's subsidiary, Hertel Aviation, L.L.C., owns and leases aircraft and
storage space to Tower Electronics, Inc.
 
    PRINCIPLES OF CONSOLIDATION:
 
    The consolidated financial statements include the operations of Tower
Electronics, Inc. and its 99% owned subsidiary, Hertel Aviation, L.L.C. (the
Subsidiary) (together referred to as the Company). All significant intercompany
accounts and transactions have been eliminated in consolidation.
 
    CASH AND CASH EQUIVALENTS:
 
    The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. The Company
keeps all of its cash and cash equivalents with one financial institution, the
same institution with which the Company has its working capital line of credit.
 
    ACCOUNTS RECEIVABLE:
 
    The Company sells its power supplies to manufacturers of electronic goods.
The Company performs ongoing credit evaluations of its customers and generally
does not require collateral. The Company maintains an allowance for potential
credit losses, which historically have been insignificant.
 
    INVENTORIES:
 
    Inventories are valued at the lower of cost or market, with cost determined
on the first-in, first-out basis.
 
    MACHINERY, EQUIPMENT, BUILDING AND IMPROVEMENTS:
 
    Machinery and equipment, recorded at cost, are depreciated using accelerated
methods over the estimated useful lives of the assets of three to seven years. A
building, recorded at cost, is depreciated using the straight-line method over
its estimated useful life of 39 years. Leasehold improvements, recorded at cost,
are amortized using the straight-line method over the shorter of the estimated
useful life of the improvements or the remaining term of the lease. The cost and
related accumulated depreciation or amortization on asset disposals are removed
from the accounts and any gain or loss thereon is included in operations.
Maintenance, repairs and minor renewals are charged to expense as incurred,
while additions and betterments are capitalized.
 
    INCOME TAXES:
 
    Tower Electronics, Inc. and its Subsidiary file separate federal and state
income tax returns. The Subsidiary is a limited liability company and files tax
returns as a partnership. As a limited liability company, all taxable income
flows through and is taxable to the Company and the minority member of the
Subsidiary.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Deferred income tax assets and liabilities are recognized for the expected
future tax consequences of differences between the financial statement and tax
bases of assets and liabilities using currently enacted tax rates in effect for
the years in which the differences are expected to reverse. Income tax expense
is the tax payable for the year and the change during the year in deferred tax
assets and liabilities.
 
    REVENUE RECOGNITION:
 
    Sales are recorded as products are shipped or services are rendered.
 
    RESEARCH AND DEVELOPMENT:
 
    Research and development costs are expensed as incurred.
 
    USE OF ESTIMATES:
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The most
significant areas which require the use of management's estimates relate to the
determination of the allowances for uncollectible accounts receivable and
inventory obsolescence and the estimated useful lives of depreciable machinery,
equipment, building and improvements.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BUSINESS DESCRIPTION:
 
    Tower Electronics, Inc. is engaged in the business of developing,
manufacturing, marketing, distributing and servicing certain power supplies,
including custom, high-performance, switching power supplies and AC/DC
converters used in the electronics and medical industries. A significant portion
of the Company's sales are concentrated in several customers (see Note 7). The
Company's subsidiary, Hertel Aviation, L.L.C., owns and leases aircraft and
storage space to Tower Electronics, Inc.
 
    PRINCIPLES OF CONSOLIDATION:
 
    The consolidated financial statements include the operations of Tower
Electronics, Inc. and its 99% owned subsidiary, Hertel Aviation, L.L.C. (the
Subsidiary) (together referred to as the Company). All significant intercompany
accounts and transactions have been eliminated in consolidation.
 
    CASH AND CASH EQUIVALENTS:
 
    The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. The Company
keeps all of its cash and cash equivalents with one financial institution, the
same institution with which the Company has its working capital line of credit.
 
    ACCOUNTS RECEIVABLE:
 
    The Company sells its power supplies to manufacturers of electronic goods.
The Company performs ongoing credit evaluations of its customers and generally
does not require collateral. The Company maintains an allowance for potential
credit losses, which historically have been insignificant.
 
    INVENTORIES:
 
    Inventories are valued at the lower of cost or market, with cost determined
on the first-in, first-out basis.
 
    MACHINERY, EQUIPMENT, BUILDING AND IMPROVEMENTS:
 
    Machinery and equipment, recorded at cost, are depreciated using accelerated
methods over the estimated useful lives of the assets of three to seven years. A
building, recorded at cost, is depreciated using the straight-line method over
its estimated useful life of 39 years. Leasehold improvements, recorded at cost,
are amortized using the straight-line method over the shorter of the estimated
useful life of the improvements or the remaining term of the lease. The cost and
related accumulated depreciation or amortization on asset disposals are removed
from the accounts and any gain or loss thereon is included in operations.
Maintenance, repairs and minor renewals are charged to expense as incurred,
while additions and betterments are capitalized.
 
    INCOME TAXES:
 
    Tower Electronics, Inc. and its Subsidiary file separate federal and state
income tax returns. The Subsidiary is a limited liability company and files tax
returns as a partnership. As a limited liability

company, all taxable income flows through and is taxable to the Company and the
minority member of the Subsidiary.
 
    Deferred income tax assets and liabilities are recognized for the expected
future tax consequences of differences between the financial statement and tax
bases of assets and liabilities using currently enacted tax rates in effect for
the years in which the differences are expected to reverse. Income tax expense
is the tax payable for the year and the change during the year in deferred tax
assets and liabilities.
 
    REVENUE RECOGNITION:
 
    Sales are recorded as products are shipped or services are rendered.
 
    RESEARCH AND DEVELOPMENT:
 
    Research and development costs are expensed as incurred.
 
    USE OF ESTIMATES:
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The most
significant areas which require the use of management's estimates relate to the
determination of the allowances for uncollectible accounts receivable and
inventory obsolescence and the estimated useful lives of depreciable machinery,
equipment, building and improvements.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
    The following unaudited pro forma condensed consolidated balance sheet as of
June 30, 1997 is based on the unaudited historical financial data of Advanced
Energy Industries, Inc. (the "Company") and of Tower Electronics, Inc. ("Tower")
and subsidiary (together, the "Tower Companies") and has been prepared as if the
acquisition of Tower had occurred on June 30, 1997. The estimated fair values
presented for the assets acquired pursuant to the terms of the acquisition are
based upon independent appraisal.
 
    The Company acquired Tower on August 15, 1997, pursuant to a Share Purchase
Agreement dated as of August 11, 1997. Tower is a designer and manufacturer of
custom, high performance switchmode power supplies that are used principally in
the telecommunications, medical and non-impact printing industries. The purchase
price consisted of $14.5 million in cash and a $1.5 million non-interest bearing
promissory note to the seller, which were delivered by the Company at closing,
as well as an earnout provision, pursuant to which the seller will be entitled
to additional consideration if Tower's sales achieve certain levels in 1998
(such sales must be at least $16 million before any amount will be payable
pursuant to the earnout provision). The promissory note matures in August 1998.
In connection with the acquisition, the Company executed a $12 million term
loan, with interest at the Prime Rate minus 0.25% (adjustable to the Prime Rate
minus 0.50% if certain financial ratios are achieved) payable quarterly and with
principal payable in twenty equal quarterly installments of $600,000, commencing
October 1, 1997. The term loan matures in August 2002, with prepayment on the
loan resulting in a penalty of 0.75% of the amount prepaid. The acquisition will
be accounted for using the purchase method of accounting and will result in a
one-time charge of $3,080,000 for in-process research and development costs in
connection with the acquisition, which is not shown in the accompanying pro
forma statements of operations since the charge is non-recurring.
 
    The following unaudited pro forma condensed consolidated statements of
operations for the year ended December 31, 1996 and for the six months ended
June 30, 1997 have been prepared as if the acquisition had occurred on January
1, 1996. The Company and the Tower Companies have fiscal year ends of December
31 and September 30, respectively. The accompanying pro forma condensed
consolidated statement of operations for the year ended December 31, 1996
includes the operating results of the Company and the Tower Companies for the
twelve months ended December 31, 1996 and September 30, 1996, respectively. The
Company believes this presentation is representative of the combined results of
operations of the Company and the Tower Companies for the twelve months ended
December 31, 1996. The accompanying pro forma condensed consolidated statement
of operations for the six months ended June 30, 1997 includes the operating
results of the Company and the Tower Companies for the six months ended June 30,
1997. Total consolidated revenues and net income of the Tower Companies for the
three months ended December 31, 1996 totaled approximately $4,255,000 and
$588,000.
 
    The pro forma information is not necessarily indicative of what the
Company's financial position or results of operations would have been had the
acquisition of Tower occurred during any of the periods presented, nor does it
purport to project the Company's financial position or results of operations for
any future periods.
 
    Concurrent with the acquisition of Tower, the Company sold a majority owned
subsidiary of Tower, Hertel Aviation, a small aircraft leasing company
("Hertel"), to the selling stockholder for an amount approximating book value.
Tower has reflected Hertel's net assets (a liability of $77,000) in the
accompanying unaudited pro forma condensed consolidated balance sheet as net
assets held for sale and included such assets in the Other Liability caption.
The disposition of Hertel is reflected within the pro forma adjustments to the
pro forma consolidated balance sheet, but not within the pro forma condensed
consolidated statements of operations since Hertel's operations were
insignificant for the periods presented.

<TABLE>
<S>        <C>
PRO FORMA BALANCE SHEET ADJUSTMENTS:
 
A.         Reflects $2,500,000 cash paid to the selling stockholder of Tower and $205,000 cash
           received from the selling stockholder of Tower in connection with certain
           transactions concurrent with the acquisition, including the collection of certain
           amounts due from the selling stockholder and the sale of Tower's wholly owned
           subsidiary, Hertel Aviation.
 
B.         Adjusted to reflect the excess of purchase price over the fair value of net assets
           acquired, or goodwill, of $7,497,000.
 
C.         Reflects a $1,500,000 non-interest bearing promissory note to the selling stockholder
           of Tower less imputed interest of $111,000 and a $12,000,000 term loan borrowed by
           the Company to effect the acquisition.
 
D.         Adjusted to reflect the disposition of Hertel Aviation's net assets (liability)
           concurrent with the acquisition transaction.
 
E.         Adjustment to eliminate the historical stockholder's equity of Tower.
 
F.         Represents $3,080,000 of purchased research and development in process which is
           expensed immediately for financial reporting purposes (the pro forma statement of
           operations does not include such charges since it is non-recurring).
 
PRO FORMA STATEMENTS OF OPERATIONS ADJUSTMENTS:
 
G.         Reflects imputed interest expense of $111,000 for the period from January 1, through
           December 31, 1996 on the one year, $1,500,000 non-interest bearing promissory note to
           the selling stockholder, and interest on the $12,000,000 term loan at the prime rate
           minus 0.25%, or a pro forma rate of 8%.
 
H.         Adjusted to reflect amortization of goodwill over an approximate 7 year period.
 
I.         Reflects the tax effect of pro forma adjustments. No tax effect is given to the
           amortization of goodwill since, for income tax reporting purposes, the historical
           basis of the net assets acquired is carried forward.
