Section 2 - Financial Information

Item 2.02 - Results of Operations and Financial Condition


On September 21, 2005, Standard Microsystems  Corporation issued a press release
announcing its financial results for its second quarter ended August 31, 2005. A
copy of the press release is attached as Exhibit 99.1.

Use of non-GAAP Financial Information

Included within the press release are non-GAAP  financial  measures  relating to
the  Company's  Consolidated   Statements  of  Operations  that  supplement  the
Company's Consolidated  Statements of Operations prepared under general accepted
accounting  principles  (GAAP).  These non-GAAP  financial  measures  adjust the
Company's  actual  results  prepared  under  GAAP to  exclude  non-cash  charges
relating to the Company's  acquisitions of OASIS  SiliconSystems  Holding AG and
Gain Technology Corporation,  and adjustments to remove the impact of provisions
to adjust  stock  appreciation  rights to their  market  value as a result of an
increase in the Company's stock price during the quarter.  The non-GAAP measures
have been reconciled to and should be considered  together with the Consolidated
Statements of Operations.  These non-GAAP measures are not meant as a substitute
for GAAP, but are included solely for  informational  and comparative  purposes.
The Company's management believes that this information is an additional measure
that assists in  evaluating  operational  trends and should not be regarded as a
replacement for corresponding GAAP measures.

The  information in Exhibit 99.1 attached hereto shall not be deemed "filed" for
purposes of Section 18 of the Securities  Exchange Act of 1934, as amended,  nor
shall it be deemed  incorporated by reference in any filing under the Securities
Act of 1933, as  amended.
