Second Quarter Fiscal 2018

Financial Results

Page 2

GAAP net sales for the second quarter of fiscal 2018 were $1,012.1 million, up16.2% from GAAP net sales of $871.4 million in the prior year's second fiscal quarter. GAAP net income from continuing operations for the second quarter of fiscal 2018 was $189.2 million, or 77 cents per diluted share, up from GAAP net income from continuing operations of $35.6 million, or 15 cents per diluted share, in the prior year's second fiscal quarter. The prior year's GAAP net income results were significantly adversely impacted by purchase accounting adjustments associated with our Atmel acquisition.

Non-GAAP net sales for the second quarter of fiscal 2018 were $1,012.1 million, up15.8% from non-GAAP net sales of $873.8 million in the prior year's second fiscal quarter. Non-GAAP net income from continuing operations for the second quarter of fiscal 2018 was $344.1 million, or $1.41 per diluted share, up56.7% from non-GAAP net income of $219.6 million, or 94 cents per diluted share, in the prior year's second fiscal quarter. For the second quarters of fiscal 2018 and fiscal 2017, our non-GAAP results exclude the effect of discontinued operations, share-based compensation, expenses related to our acquisition activities (including intangible asset amortization, inventory valuation costs, severance costs, and legal and other general and administrative expenses associated with acquisitions), revenue recognition changes related to Atmel distributors resulting from changes to business practices with those distributors, non-cash interest expense on our convertible debentures, the related income tax implications of these items, tax adjustments in accordance with ASC 740-270 and non-recurring tax events. Our year-to-date non-GAAP results include all of the aforementioned adjustments plus the effect of a manufacturing excursion issue with one of our suppliers, preclusion of revenue recognition under GAAP for inventory in the distribution channel on the acquisition dates of our acquisitions, a loss on the settlement of our convertible debentures, a gain on an equity method investment, and the related income tax implications of these items. A reconciliation of our non-GAAP and GAAP results is included in this press release.

Microchip announced today that its Board of Directors has declared a record quarterly cash dividend on its common stock of 36.25 cents per share. The quarterly dividend is payable on December 5, 2017 to stockholders of record on November 21, 2017.

"In the September 2017 quarter we achieved our first quarter of over one billion dollars in net sales! Our net sales year-over-year in the September quarter were up 16.2% on a GAAP basis and 15.8% on a non-GAAP basis," said Steve Sanghi, Chief Executive Officer. "Our quarterly financial results were very strong and we set new records in net sales, operating income and earnings per diluted share. We are making outstanding progress in moving towards our long-term operating model."

Mr. Sanghi added, "Our organic growth continues to thrive with our Microchip 2.0 initiative. Microchip 2.0 combines the product, technology, system and employee strengths of Microchip and its previous acquisitions and allows us to provide Total System Solutions to our customers by selling multiple solutions into the circuit boards that drive their end applications."

"Our Microcontroller businesses performed very strongly in the September quarter with revenue being up 4.7% sequentially compared to the June quarter, setting a new record in the process," said Ganesh Moorthy, President and Chief Operating Officer. "Each of our 8-bit, 16-bit and 32-bit microcontroller product families set new revenue records in the quarter and our product portfolio and roadmap have never been stronger."

Mr. Moorthy added, "Our transformation to Microchip 2.0 with a more powerful Total System Solution approach is enabling us to successfully find more opportunities to win new designs and attach Microchip's vast portfolio of analog products in our customers' applications. This effort should contribute to further revenue growth over time as these design wins go to production."

Eric Bjornholt, Microchip's Chief Financial Officer, said, "Cash flow from operations in the September quarter was a record $350.1 million. As of September 30, 2017, the cash and total investment position on our balance sheet was $1.844 billion."

Mr. Bjornholt added, "Our inventory at September 30, 2017 was 105 days and grew by five days from the June quarter levels. Inventory days are still well below our targeted levels, but we are starting to see improvement from our continued capacity expansion efforts."

Commenting on the business environment, Mr. Sanghi added, "We are continuing to see a strong business environment for our products worldwide and have a number of company-specific demand drivers. Bookings continued to be very strong in the September quarter. We have added capacity and are continuing to add capacity in our factories around the world. We are seeing improvement in our inventory position and our lead times are improving for many of our products."

Mr. Sanghi concluded, "Reflecting better than normal seasonality, we expect total net sales to be flat to down 4% sequentially, which at the midpoint would represent 12.6% growth on a non-GAAP basis year-over-year and 18.9% on a GAAP basis year-over-year."

Microchip's Highlights for the Quarter Ended September 30, 2017:

• Our new power monitoring IC, the PAC1934, increases software power measurement accuracy to 99 percent in Windows 10 devices, including laptops, tablets and mobile phones.

¹    See the "Use of Non-GAAP Financial Measures" section of this release.

²    See Footnote 2 under the "Use of Non-GAAP Financial Measures" section of this release.

³    Earnings per share has been calculated based on the diluted shares outstanding of Microchip on a consolidated basis.

• Microchip's inventory days in the December 2017 quarter are expected to grow as we continue to make progress in moving towards our longer-term target of 115 to 120 days of inventory. Our actual inventory level will depend on the inventory that our distributors decide to hold to support their customers, overall demand for our products and our production levels.

• Capital expenditures for the quarter ending December 31, 2017 are expected to be approximately $70 million. Capital expenditures for all of fiscal year 2018 are expected to be between $200 million and $220 million. We are continuing to invest in the equipment needed to support the growth of our production capabilities for fast growing new products and technologies.

¹  Use of Non-GAAP Financial Measures: Our non-GAAP adjustments, where applicable, include the effect of discontinued operations, share-based compensation, expenses related to our acquisition activities (including intangible asset amortization, inventory valuation costs, severance costs, and legal and other general and administrative expenses associated with acquisitions), revenue recognition changes related to Atmel distributors resulting from changes to business practices with those distributors, non-cash interest expense on our convertible debentures, the related income tax implications of these items, tax adjustments in accordance with ASC 740-270 and non-recurring tax events. Our year-to-date non-GAAP results include all of the aforementioned adjustments

plus the effect of a manufacturing excursion issue with one of our suppliers, preclusion of revenue recognition under GAAP for inventory in the distribution channel on the acquisition dates of our acquisitions, a loss on the settlement of our convertible debentures, a gain on an equity method investment, and the related income tax implications of these items.

We are required to estimate the cost of certain forms of share-based compensation, including employee stock options, restricted stock units and our employee stock purchase plan, and to record a commensurate expense in our income statement. Share-based compensation expense is a non-cash expense that varies in amount from period to period and is affected by the price of our stock at the date of grant. The price of our stock is affected by market forces that are difficult to predict and are not within the control of management. Our other non-GAAP adjustments are either non-cash expenses, unusual or infrequent items or other expenses related to transactions. Management excludes all of these items from its internal operating forecasts and models.

We are using non-GAAP net sales, non-GAAP gross profit, non-GAAP gross profit percentage, non-GAAP operating expenses in dollars and as a percentage of sales including non-GAAP research and development expenses and non-GAAP selling, general and administrative expenses, non-GAAP operating income, non-GAAP other expense, net, non-GAAP income tax rate, non-GAAP net income from continuing operations, and non-GAAP diluted earnings per share from continuing operations which exclude the items noted above, as applicable, to permit additional analysis of our performance.

Management believes these non-GAAP measures are useful to investors because they enhance the understanding of our historical financial performance and comparability between periods. Many of our investors have requested that we disclose this non-GAAP information because they believe it is useful in understanding our performance as it excludes non-cash and other charges that many investors feel may obscure our underlying operating results. Management uses these non-GAAP measures to manage and assess the profitability of our business. Specifically, we do not consider such items when developing and monitoring our budgets and spending. Our determination of the above non-GAAP measures might not be the same as similarly titled measures used by other companies, and it should not be construed as a substitute for amounts determined in accordance with GAAP. There are limitations associated with using non-GAAP measures, including that they exclude financial information that some may consider important in evaluating our performance. Management compensates for this by presenting information on both a GAAP and non-GAAP basis for investors and providing reconciliations of the GAAP and non-GAAP results.

²  Generally, gross margin fluctuates over time, driven primarily by the mix of microcontrollers, mixed-signal products, analog products and memory products sold and licensing revenue; variances in manufacturing yields; fixed cost absorption; wafer fab loading levels; costs of wafers from foundries; inventory reserves; pricing

pressures in our non-proprietary product lines; and competitive and economic conditions. Operating expenses fluctuate over time, primarily due to net sales and profit levels.

³  Diluted Common Shares Outstanding can vary for, among other things, the trading price of our common stock, the exercise of options or vesting of restricted stock units, the potential for incremental dilutive shares from our convertible debentures (additional information regarding our share count is available in the investor relations section of our website under the heading "Supplemental Financial Information"), and repurchases or issuances of shares of our common stock. The diluted common shares outstanding presented in the guidance table above assumes an average Microchip stock price in the December 2017 quarter between $93 and $97 per share (however, we make no prediction as to what our actual share price will be for such period or any other period and we cannot estimate what our stock option exercise activity will be during the quarter).
