<P align="left" style="font-size: 12pt"><B>First Quarter 2018 Financial Results</B>


<P align="left" style="font-size: 12pt; text-indent: 2%">Revenue was $554&nbsp;million, an increase of 8% from $512&nbsp;million in the fourth quarter of 2017
and an increase of 27% from $437&nbsp;million in the first quarter of 2017.


<P align="left" style="font-size: 12pt; text-indent: 2%">Net income was $105&nbsp;million, or $1.90 per diluted share, compared to net income of $77.6
million, or $1.41 per diluted share, in the fourth quarter of 2017, and $65.1&nbsp;million, or $1.18 per
diluted share, in the first quarter of 2017.


<P align="left" style="font-size: 12pt; text-indent: 2%">Non-GAAP net earnings, which exclude special charges and credits, were $114.3&nbsp;million, or
$2.07 per diluted share, compared to $94.6&nbsp;million, or $1.71 per diluted share, in the fourth
quarter of 2017, and $70.0&nbsp;million, or $1.27 per diluted share, in the first quarter of 2017.


<P align="left" style="font-size: 12pt; text-indent: 2%">Sales to semiconductor customers were $313&nbsp;million, an increase of 26% compared to the first
quarter of 2017, and sales to advanced markets were $241&nbsp;million, an increase of 28% compared to
the first quarter of 2017.


<P align="left" style="font-size: 12pt; text-indent: 2%">Sales in the Vacuum and Analysis Division set another quarterly record of $348&nbsp;million, an
increase of 25% from the first quarter a year ago. Sales in the Light and Motion Division also set
another quarterly record of $206&nbsp;million, an increase of 29% from the prior year period.


<P align="left" style="font-size: 12pt; text-indent: 2%">&#147;We are very pleased with our strong start in 2018, which has fueled our ability to achieve
our objectives of sustainable and profitable growth,&#148; said Gerald Colella, Chief Executive Officer
and President. Mr.&nbsp;Colella added, &#147;We again set new records for quarterly revenue and Non-GAAP net
earnings as well as achieving new revenue records in both the semiconductor market and advanced
markets we serve. Our strong focus on solving complex customer problems is a significant driver in
the 28% year over year revenue growth in our advanced markets. These advanced markets represent
almost 45% of our total revenue and provide MKS a unique additive growth opportunity to our strong
leading position in the semiconductor market.&#148;


<P align="left" style="font-size: 12pt; text-indent: 2%">&#147;We also continue to execute on our strategy to delever our balance sheet and significantly
reduce our interest cost,&#148; said Seth Bagshaw, Senior Vice President and Chief Financial Officer.
&#147;In March&nbsp;2018, we voluntarily pre-paid another $50&nbsp;million of principal on our Term Loan.
Furthermore, on April&nbsp;11, 2018, we completed our fourth successful repricing of our Term Loan. Our
debt balance as of March&nbsp;31,<sup> </sup>2018, was $348&nbsp;million, down from $780&nbsp;million at loan
origination in April&nbsp;2016; our debt to Adjusted EBITDA ratio is well below one times; and we have
reduced our non-GAAP interest expense by over 70% since origination on an annualized basis.&#148;


<P align="left" style="font-size: 12pt"><B>Additional Financial Information</B>


<P align="left" style="font-size: 12pt; text-indent: 2%">The Company had $542&nbsp;million in cash and short-term investments as of March&nbsp;31, 2018 and
during the first quarter of 2018, MKS paid a dividend of $9.8&nbsp;million or $0.18 per diluted share.


<P align="left" style="font-size: 12pt"><B>Second Quarter 2018 Outlook</B>


<P align="left" style="font-size: 12pt; text-indent: 2%">Based on current business levels, the Company expects that revenue in the second quarter of
2018 could range from $550 to $590&nbsp;million.


<P align="left" style="font-size: 12pt; text-indent: 2%">At these volumes, GAAP net income could range from $1.91 to $2.18 per diluted share and
non-GAAP net earnings could range from $2.09 to $2.36 per diluted share. This financial guidance
incorporates assumptions made based upon the Company&#146;s current interpretation of the 2017 Tax Cut
and Jobs Act, and may change as additional clarification and implementation guidance is issued.


<P align="left" style="font-size: 12pt"><B>Conference Call Details</B>

<P align="left" style="font-size: 12pt"><B>Use of Non-GAAP Financial Results</B>


<P align="left" style="font-size: 12pt; text-indent: 2%">This release includes measures that are not in accordance with U.S. generally accepted
accounting principles (&#147;non-GAAP measures&#148;). Non-GAAP measures exclude amortization of acquired
intangible assets, asset impairments, costs associated with completed and announced acquisitions,
acquisition integration costs, an inventory step-up adjustment related to an acquisition,
restructuring charges, certain excess and obsolete inventory charges, fees and expenses related to
the re-pricings of our term loan, amortization of debt issuance costs, net proceeds from an
insurance policy, costs associated with the sale of a business, the tax effect of the 2017 Tax Cut
and Jobs Act, the tax effect of legal entity restructurings, other discrete tax benefits and
charges, and the related tax effect of these adjustments. These non-GAAP measures should be viewed
in addition to, and not as a substitute for, MKS&#146; reported results, and may be different from
non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on
any comprehensive set of accounting rules or principles. MKS management believes the presentation
of these non-GAAP measures is useful to investors for comparing prior periods and analyzing ongoing
business trends and operating results. Annualized GAAP interest expense based upon $780&nbsp;million
principal outstanding and using the LIBOR based interest rate spread in effect on April&nbsp;29, 2016,
was $44&nbsp;million and included $5&nbsp;million in debt issuance cost. Annualized GAAP interest expense
based upon $348&nbsp;million in principal currently outstanding and LIBOR plus 175 basis points is $14.5
million and includes $3.1&nbsp;million of debt issuance cost.

affiliated with our Term Loan Credit Agreement and ABL Facility.


<P align="left" style="font-size: 10pt">Note 4: We recorded restructuring costs, primarily comprised of severance costs related to
transferring a portion of our shared service functions to a third party as well as the
consolidation of certain shared service functions in Asia during the three months ended March&nbsp;31,
2018. We recorded restructuring costs during the three months ended December&nbsp;31, 2017 and March&nbsp;31,
2017, primarily related to the restructuring of one of our international sales facilities and the
consolidation of certain sales offices and manufacturing plants.


<P align="left" style="font-size: 10pt">Note 5: We recorded additional environmental costs during the three months ended March&nbsp;31, 2018,
related to an EPA-designated Superfund site, which was acquired as part of our Newport acquisition.


<P align="left" style="font-size: 10pt">Note 6: Windfall tax benefits on the vesting of stock-based compensation relate to an accounting
standard issued by the Financial Statement Accounting Standards Board (Accounting Standards Update
2016-09).


<P align="left" style="font-size: 10pt">Note 7: We recorded a provisional deferred tax adjustment, which also includes the reversal of a

ended December&nbsp;31, 2017 and updated the provisional deferred tax adjustment in the three months
ended March&nbsp;31, 2018.


<P align="left" style="font-size: 10pt">Note 8*: We recorded a provisional transition tax on accumulated foreign earnings related to the
2017 Tax Cut and Jobs Act during the three months ended December&nbsp;31, 2017 and updated the

related to the 2017 Tax Cut and Jobs Act during the three months ended December&nbsp;31, 2017.


<P align="left" style="font-size: 10pt">*The computation of the one-time tax on our offshore earnings pursuant to the 2017 Tax Cut and Jobs
Act (the &#147;Tax Act&#148;) as well as our net deferred tax liability is based on our current understanding
and assumptions regarding the impact of the Tax Act, and may change as additional clarification and
implementation guidance is issued and as the interpretation of the Tax Act evolves over time.


<P align="left" style="font-size: 10pt">Note 11: We historically recorded the revenue and related cost of revenue for our spare parts
within Products in our Statement of Operations for the Vacuum and Analysis Division. We have now
determined that these items are better reflected within Services in our Statement of Operations and
have revised the presentation of our previously issued financial statements as shown below:

consolidation of certain sales offices and manufacturing plants.


<P align="left" style="font-size: 9.5pt">Note 5: We recorded additional environmental costs during the three months ended March&nbsp;31, 2018,
related to an EPA-designated Superfund site, which was acquired as part of our Newport acquisition.


<P align="left" style="font-size: 9.5pt">Note 6: Windfall tax benefits on the vesting of stock-based compensation relate to an accounting

<P align="left" style="font-size: 9.5pt">Note 8*: We recorded a provisional transition tax on accumulated foreign earnings related to the
2017 Tax Cut and Jobs Act during the three months ended December&nbsp;31, 2017 and updated the

Act (the &#147;Tax Act&#148;) as well as our net deferred tax liability is based on our current understanding
and assumptions regarding the impact of the Tax Act, and may change as additional clarification and
implementation guidance is issued and as the interpretation of the Tax Act evolves over time.
