Pricing Term Sheet

dated as of March 20, 2025

Issuer:

Microchip Technology Incorporated.

Ticker / Exchange for the Common Stock:

MCHP / The Nasdaq Global Select Market (“Nasdaq”).

Pricing Date:

March 20, 2025.

Trade Date:

March 21, 2025 (“T”).

Settlement Date:

March 25, 2025 (T+2), which is the second business day following the trade date for the Depositary Shares (such settlement cycle being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Depositary Shares prior to the business day preceding the settlement date will be required, by virtue of the fact that the Depositary Shares initially will settle T+2, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Depositary Shares who wish to trade the Depositary Shares prior to the business day preceding the settlement date should consult their own advisors.

Use of Proceeds:

The Issuer expects the net proceeds from the Depositary Shares Offering to be approximately $1.32 billion (or approximately $1.45 billion if the underwriters of the Depositary Shares Offering exercise in full their over-allotment option to purchase additional Depositary Shares) after deducting the underwriting discount and the Issuer’s estimated offering expenses totaling approximately $2.1 million. The Issuer intends to use approximately $50.1 million of the net proceeds of the Depositary Shares Offering to pay the cost of the capped call transactions as described in the Preliminary Prospectus Supplement. If the underwriters exercise their over-allotment option to purchase additional Depositary Shares, the Issuer expects to use a portion of the net proceeds from the sale of such additional Depositary Shares to enter into additional capped call transactions. The Issuer intends to use the remaining net proceeds to repay existing debt, including notes outstanding under the Issuer’s commercial paper program. See “Use of Proceeds” in the Preliminary Prospectus Supplement.

Depositary Shares Offered:

27,000,000 Depositary Shares, each of which represents a 1/20th interest in a share of the Issuer’s 7.50% Series A Mandatory Convertible Preferred Stock (the “Mandatory Convertible Preferred Stock”). At settlement of the Depositary Shares Offering, the Issuer will issue 1,350,000 shares of Mandatory Convertible Preferred Stock, subject to the underwriters’ over-allotment option.

2,700,000 additional Depositary Shares (corresponding to 135,000 additional shares of the Mandatory Convertible Preferred Stock), solely to cover over-allotments.

Public Offering Price:

$50.00 per Depositary Share.

Dividends:

7.50% of the liquidation preference of $1,000 per share of the Mandatory Convertible Preferred Stock per year. Dividends will accumulate from the Settlement Date and, to the extent that the Issuer is legally permitted to pay dividends and its board of directors, or an authorized committee thereof, declares a dividend payable with respect to the Mandatory Convertible Preferred Stock, the Issuer will pay such dividends in cash or, subject to certain limitations, by delivery of shares of the Issuer’s common stock, par value $0.001 per share (the “Common Stock”) or through any combination of cash and shares of Common Stock, as determined by the Issuer’s board of directors (or an authorized committee thereof) in its sole discretion; provided that any unpaid dividends will continue to accumulate. The expected dividend payable on the first Dividend Payment Date is $16.875 per share of Mandatory Convertible Preferred Stock (equivalent to approximately $0.8438 per Depositary Share). Each subsequent dividend is expected to be $18.75 per share of Mandatory Convertible Preferred Stock (equivalent to $0.9375 per Depositary Share).

Dividend Record Dates:

The March 1, June 1, September 1 and December 1 immediately preceding the relevant Dividend Payment Date.

Dividend Payment Dates:

March 15, June 15, September 15 and December 15 of each year, commencing on, and including, June 15, 2025 and ending on, and including, March 15, 2028.

Mandatory Conversion Date:

The second business day immediately following the last trading day of the 20 consecutive trading day period beginning on, and including, the 21st scheduled trading day immediately preceding March 15, 2028.

Initial Price:

Equal to $1,000, divided by the Maximum Conversion Rate, rounded to the nearest $0.0001, which initially is $50.9996.

Threshold Appreciation Price:

Equal to $1,000, divided by the Minimum Conversion Rate, rounded to the nearest $0.0001, which initially is $62.4766 and represents an approximately 22.5% appreciation over the Initial Price.

Floor Price:

$17.85 (approximately 35% of the Initial Price), subject to adjustment as described in the Preliminary Prospectus Supplement.

The conversion rate for each share of Mandatory Convertible Preferred Stock will not be more than 19.6080 shares of Common Stock and not less than 16.0060 shares of Common Stock (respectively, the “Maximum Conversion Rate” and “Minimum Conversion Rate”), depending on the applicable market value (as defined in the Preliminary Prospectus Supplement) of the Common Stock, as described below and subject to certain anti-dilution adjustments. Correspondingly, the conversion rate per Depositary Share will be not more than 0.9804 shares of Common Stock and not less than 0.8003 shares of Common Stock.

The following table illustrates the conversion rate per share of the Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments described in the Preliminary Prospectus Supplement, based on the applicable market value of the Common Stock:

Optional Conversion:

Other than during a fundamental change conversion period (as defined in the Preliminary Prospectus Supplement), at any time prior to March 15, 2028, a holder of Mandatory Convertible Preferred Stock may elect to convert such holder’s shares of Mandatory Convertible Preferred Stock, in whole or in part, at the Minimum Conversion Rate of 16.0060 shares of Common Stock per share of Mandatory Convertible Preferred Stock (equivalent to 0.8003 shares of Common Stock per Depositary Share), subject to adjustment as described in the Preliminary Prospectus Supplement. Because each Depositary Share represents a 1/20th fractional interest in a share of Mandatory Convertible Preferred Stock, a holder of Depositary Shares may convert its Depositary Shares only in lots of 20 Depositary Shares.

Fundamental Change:

If a fundamental change (as defined in the Preliminary Prospectus Supplement) occurs on or prior to March 15, 2028, holders of the Mandatory Convertible Preferred Stock will have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part, into shares of Common Stock at the fundamental change conversion rate (as defined in the Preliminary Prospectus Supplement) during the period beginning on, and including, the effective date (as defined in the Preliminary Prospectus Supplement) of such fundamental change and ending on, and including, the earlier of (a) the date that is 20 calendar days after such effective date (or, if later, the date that is 20 calendar days after holders receive notice of such fundamental change) and (b) March 15, 2028. For the avoidance of doubt, the period described in the immediately preceding sentence may not end on a date that is later than March 15, 2028.

The following table sets forth the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock (subject to adjustment as described in the Preliminary Prospectus Supplement) based on the effective date of the fundamental change and the stock price (as defined in the Preliminary Prospectus Supplement) in the fundamental change:

Effective Date

March 25, 2025

March 15, 2026

March 15, 2027

March 15, 2028

The exact stock price and effective date may not be set forth in the table, in which case:

•  if the stock price is between two stock prices on the table or the effective date is between two effective dates on the table, the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock will be determined by straight-line interpolation between the fundamental change conversion rates per share of Mandatory Convertible Preferred Stock set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day or 366-day year, as applicable;

•  if the stock price is in excess of $85.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Preliminary Prospectus Supplement), then the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock will be the Minimum Conversion Rate; and

•  if the stock price is less than $17.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Preliminary Prospectus Supplement), then the fundamental change conversion rate per share of Mandatory Convertible Preferred Stock will be the Maximum Conversion Rate.

The following table sets forth the fundamental change conversion rate per Depositary Share (subject to adjustment as described in the Preliminary Prospectus Supplement) based on the effective date of the fundamental change and the stock price in the fundamental change:

Effective Date

March 25, 2025

March 15, 2026

March 15, 2027

March 15, 2028

The exact stock price and effective date may not be set forth in the table, in which case:

•  if the stock price is between two stock prices on the table or the effective date is between two effective dates on the table, the fundamental change conversion rate per Depositary Share will be determined by straight-line interpolation between the fundamental change conversion rates per Depositary Share set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day or 366-day year, as applicable;

•  if the stock price is in excess of $85.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Preliminary Prospectus Supplement), then the fundamental change conversion rate per Depositary Share will be the Minimum Conversion Rate, divided by 20; and

•  if the stock price is less than $17.00 per share (subject to adjustment in the same manner as the stock prices in the column headings of the table above as described in the Preliminary Prospectus Supplement), then the fundamental change conversion rate per Depositary Share will be the Maximum Conversion Rate, divided by 20.

On any conversion date for the Mandatory Convertible Preferred Stock, each Depositary Share corresponding to the shares of Mandatory Convertible Preferred Stock so converted will be entitled to receive 1/20th of the number of shares of Common Stock and the amount of any cash received by the bank depositary upon conversion of each share of Mandatory Convertible Preferred Stock.

The discount rate for purposes of determining the fundamental change dividend make-whole amount (as defined in the Preliminary Prospectus Supplement) is 4.95% per annum.

The Issuer intends to apply to list the Depositary Shares on the Nasdaq Global Select Market under the symbol “MCHPP.” No assurance can be given that the Depositary Shares will be listed or that any such application for listing will be approved.
