Rhea-AI Filing Summary

AMETEK is offering senior notes in a preliminary prospectus supplement subject to completion. The notes are unsecured senior obligations ranking equally with AMETEK’s existing and future senior unsecured, unsubordinated debt. They would be effectively subordinated to secured debt to the extent of the collateral and to indebtedness of AMETEK’s subsidiaries.

AMETEK intends to use the net proceeds, together with proceeds from concurrent Euro and Canadian dollar note offerings, to repay all or a portion of borrowings under its financing agreements and/or commercial paper obligations, and for general corporate purposes. The concurrent offerings are not contingent on one another. The notes have no established trading market, and AMETEK does not intend to seek an exchange listing or quotation.

5 terms

effectively subordinated financial

"effectively subordinated to any future secured indebtedness"

Debt or claims that are not legally listed as lower priority but, in practice, will be paid after other creditors because of the company’s structure or secured claims. Think of it like standing behind people who are already in line: even if your ticket says you’re next, the way the lines are organized means others get served first, so your chance of getting paid in a default is reduced accordingly.

Change of Control Repurchase Event financial

"If a Change of Control Repurchase Event occurs"

A change of control repurchase event happens when a company is sold or otherwise taken over and that sale triggers contractual rights for holders of stock, options, or debt to force the company to buy their securities back for cash. Think of it like a lease that lets the tenant cash out when the building is sold: it gives certain investors a predictable exit price and timeline. This matters because it can change who owns the company, alter cash on hand, affect future returns and dilution, and influence how attractive a takeover or investment looks.

Term SOFR financial

"at a rate equal to either a Term SOFR rate or an alternate base rate"

Term SOFR is a benchmark interest rate that reflects the cost of borrowing money over a specific period, based on actual transactions in the financial markets. It is used by lenders and borrowers to set the interest rates on loans and financial contracts, helping to ensure rates are fair and transparent. For investors, understanding term SOFR helps gauge borrowing costs and the overall direction of interest rates in the economy.

Financial Covenant Transition Date financial

"prior to a Financial Covenant Transition Date"

Attributable Debt financial

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What does AMETEK pay if its notes are repurchased after a change of control?

If a Change of Control Repurchase Event occurs, AMETEK must offer to repurchase the notes for cash at 101% of principal, plus accrued and unpaid interest through, but not including, the repurchase date, unless the notes have already been redeemed. The defined event requires both a Change of Control and a Rating Decline.

Will AMETEK’s notes be listed or have a public trading market?

AMETEK does not intend to list or quote the notes, which have no established trading market. The underwriters currently intend to make a market, but they are not obligated to do so and may discontinue market-making without notice.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein, include “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995 and the provisions of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Such forward-looking statements are based on our management’s assumptions and beliefs about future events or circumstances using information currently available, and as a result, they are subject to risks and uncertainties. Forward-looking statements address events or developments that AMETEK expects or believes may or will occur in the future. These forward-looking statements, which address the Company’s expected business and financial performance and financial condition, among other matters, may contain words and terms such as: “may,” “will,” “should,” “could,” “believe,” “anticipate,” “expect,” “estimate,” “plan” or other comparable terminology.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about expected earnings, revenues, growth, liquidity, effective tax rate, interest rates, the expected timing for the closing of certain acquisitions or other matters. Although the Company believes the expectations reflected in all forward-looking statements are based upon reasonable assumptions, the expectations may not be attained or there may be material deviation. Readers and investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in these forward-looking statements:

•

our ability to consummate and successfully integrate future acquisitions;

•

risks associated with international sales and operations, including supply chain disruptions;

•

tariffs, trade disputes, foreign currency fluctuations and geopolitical developments;

•

our ability to successfully develop new products, open new facilities or transfer product lines;

•

the price and availability of raw materials;

•

cybersecurity and information technology risks;

•

compliance with government regulations, including environmental regulations;

•

changes in the competitive environment;

•

the effects of competition in our markets;

•

the ability to maintain adequate liquidity and financing sources; and

•

general economic conditions affecting the industries we serve.

A description of some of these uncertainties and other risks is set forth under the caption “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which is incorporated by reference herein, as well as other reports filed with the SEC, including, but not limited to, our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. There may be other risks and uncertainties not identified in these documents that we either currently do not expect to have an adverse effect on our business or that we are unable to predict or identify at the time of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Our forward-looking statements may also be impacted by, among other things, future tax, regulatory and other legal changes that may arise in any of the jurisdictions in which we operate.

The Company undertakes no obligation to update or revise any forward-looking statements except as required by law.

Our products are marketed and sold worldwide through two operating groups: Electronic Instruments (“EIG”) and Electromechanical (“EMG”). EIG is a leader in the design and manufacture of advanced instruments for the process, power and industrial, and aerospace markets.

Recent Developments

Indicor Acquisition

The Indicor Acquisition closed on August 26, 2026. We used cash on hand, commercial paper borrowings, and borrowings under the Financing Agreements (as defined below), to pay the cash consideration for the Indicor Acquisition and the payment of fees and expenses related to the Indicor Acquisition. We intend to use the net proceeds from this offering to repay all or a portion of the outstanding borrowings under the Financing Agreements and/or our outstanding commercial paper obligations, and for general corporate purposes. See “Use of Proceeds.”

Indicor Instrumentation is a group of leading businesses that design and manufacture mission-critical solutions for demanding industrial and scientific applications. Its products serve customers across attractive end markets that align closely with AMETEK’s existing portfolio and generate a substantial base of recurring revenue from consumables, services and aftermarket support. The Indicor Instrumentation businesses joined AMETEK’s EIG and EMG based on product offerings and market alignment.

Financing Transactions

Amendment and Restatement of Revolving Credit Facility

On June 9, 2026, together with certain of our foreign subsidiaries, we entered into an Amended and Restated Credit Agreement (the “Revolving Credit Agreement”) with the lenders party thereto, JPMorgan Chase Bank, N.A. and J.P. Morgan SE, as administrative agents, and Bank of America, N.A., PNC Bank, National Association, Truist Bank and Wells Fargo Bank, National Association, as co-syndication agents.

The Revolving Credit Agreement increased the aggregate amount of the lenders’ commitments to make revolving loans (“Revolving Loans”) from $2.3 billion to $3.5 billion and extended the maturity date to June 9, 2031, subject to extensions as further detailed in the Revolving Credit Agreement. The Revolving Credit Agreement contains affirmative and negative covenants and includes limitations on indebtedness, liens, fundamental changes and asset sales (which are subject to certain exceptions and thresholds) and certain financial covenants including compliance with either a maximum total net leverage ratio or, following satisfaction of a financial covenant transition condition, a minimum interest coverage ratio.

S-1

Table of Contents

Term Loan Facility

On June 9, 2026, the Company also entered into a Term Loan Credit Agreement (the “Term Loan Agreement”, and together with the Revolving Credit Agreement, the “Financing Agreements”), among the Company, the lenders party thereto, Bank of America, N.A., as administrative agent, and JPMorgan Chase Bank, N.A., PNC Bank, National Association, Truist Bank and Wells Fargo Bank, National Association, as syndication agents.

The Term Loan Agreement provides for a senior unsecured term loan facility of up to $4.0 billion consisting of three tranches: (a) $1.625 billion of term loans that will mature three years from the date on which they are drawn (“Tranche A Loans”), (b) $1.625 billion of term loans that will mature four years from the date on which they are drawn (“Tranche B Loans”) and (c) $750 million of term loans that will mature five years from the date on which they are drawn (“Tranche C Loans” and, together with the Tranche A Loans and the Tranche B Loans, the “Term Loans”).

The funding of the Term Loans was subject to customary conditions, including the consummation of the Indicor Acquisition. The proceeds of the Term Loans were only permitted to be used in connection with the Indicor Acquisition. In connection with the closing of the Indicor Acquisition, the Company drew the full $4.0 billion available under the Term Loan Agreement.

The Term Loans bear interest at a rate equal to either a Term SOFR rate or an alternate base rate, in each case, plus an applicable margin based on the Company’s credit rating or leverage level, as elected by the Company. The Company has the right to prepay the Term Loans at any time, in whole or in part and without premium or penalty (other than, if applicable, any breakage costs). The Company may also choose to reduce its commitments under the Term Loan Agreement at any time.

The covenants contained in the Term Loan Agreement are substantially similar to the covenants contained in the Revolving Credit Agreement. The Term Loan Agreement contains affirmative and negative covenants and includes limitations on indebtedness, liens, fundamental changes and asset sales (which are subject to certain exceptions and thresholds) and certain financial covenants requiring compliance with either a maximum total net leverage ratio or, following satisfaction of a financial covenant transition condition, a minimum interest coverage ratio. The Term Loan Agreement also contains customary events of default (which are in some cases subject to certain exceptions, thresholds and grace periods) including, but not limited to, nonpayment of principal and interest, failure to perform or observe covenants, breaches of representations and warranties and certain bankruptcy-related events.

Bridge Facility

In connection with entering into the Purchase Agreement for the Indicor Acquisition, we obtained $5.0 billion in bridge financing commitments to fund the Indicor Acquisition. As a result of entering into the Revolving Credit Agreement and the Term Loan Agreement, such bridge financing commitments have been automatically reduced and terminated in full.

Concurrent Securities Offerings

Concurrently with this offering, we expect to offer € aggregate principal amount of one or more tranches of euro-denominated senior notes (collectively, the “Euro notes”) (the “Euro Offering”) and C $ aggregate principal amount of one or more tranches of Canadian dollar-denominated senior notes (collectively, the “Canadian dollar notes”) (the “Canadian Dollar Offering”, and collectively with the Euro Offering, the “Concurrent Securities Offerings”) pursuant to separate prospectus supplements. We expect to use the net proceeds of the Concurrent Securities Offerings to repay all or a portion of the outstanding borrowings under the Financing Agreements and/or our outstanding commercial paper obligations and for general corporate purposes.

This offering, the Euro Offering and the Canadian Dollar Offering are not contingent upon one another. This prospectus supplement does not constitute an offer to sell any securities other than the notes. There can be no assurance that any of the Concurrent Securities Offerings will be completed on the terms described herein, or at all. The closing of each Concurrent Securities Offering is subject to the satisfaction of customary closing conditions.

Ranking

The notes will:

•

be our general unsecured senior obligations;

•

be effectively subordinated in right of payment to any future secured indebtedness to the extent of the value of the assets securing such debt;

•

be effectively subordinated to any indebtedness of our subsidiaries;

•

rank equally in right of payment with all of our existing and future unsecured and unsubordinated indebtedness, including indebtedness under our Financing Agreements and Concurrent Securities Offerings;

S-3

Table of Contents

•

we would have had approximately $ billion of unsecured and unsubordinated indebtedness (including the Financing Agreements, the Concurrent Securities Offerings, our commercial paper program and the notes), all of which would constitute senior indebtedness;

•

we would have had no secured indebtedness to which the notes would have been effectively subordinated; and

•

our subsidiaries would have had approximately $16,000 of indebtedness to which the notes would have been effectively subordinated.

Covenants

We will issue the notes under an indenture with U.S. Bank Trust Company, National Association, as trustee. The indenture, among other things, limits our ability to:

•

incur liens on Principal Property (as defined under “Description of the Notes”);

•

engage in certain sale/leaseback transactions; and

•

consolidate or merge with or into, or sell all or substantially all of our assets to, another person.

These covenants are subject to a number of important exceptions and qualifications. For more details, see “Description of Debt Securities — Covenants” in the accompanying prospectus and “Description of the Notes — Covenants” in this prospectus supplement.

Absence of Public Market for the Notes

The notes are a new issue of securities with no established trading market. We do not intend to apply for a listing of the notes on any securities exchange or any automated dealer quotation system. Accordingly, we cannot assure you as to the development or liquidity of any market for the notes. The underwriters have advised us that they currently intend to make a market in the notes. However, they are not obligated to do so and any market making with respect to the notes may be discontinued without notice. See “Risk Factors — Your ability to transfer the notes may be limited since there is no public market for the notes, and we do not know if an active trading market will ever develop, or if a market does develop, whether it will be sustained” in this prospectus supplement.

Use of Proceeds

We anticipate that the net proceeds from the offering, after deducting the underwriting discount and offering expenses payable by us, will be approximately $ million. We intend to use the net proceeds from this offering, and the Concurrent Securities Offerings, to repay all or a portion of the outstanding borrowings under the Financing Agreements and/or our commercial paper obligations, and for general corporate purposes. Such borrowings were incurred to pay a portion of the cash consideration for the Indicor Acquisition and pay related fees and expenses. For more information, see “— Recent Developments — Indicor Acquisition” and “Use of Proceeds”.

Conflicts of Interest

As described under “Use of Proceeds,” we intend to use the net proceeds of this offering and the Concurrent Securities Offerings to repay all or a portion of the outstanding borrowings under the

S-4

Table of Contents

Financing Agreements and/or our commercial paper borrowings. As such, certain of the underwriters and their affiliates, who are lenders under our Financing Agreements or may own our commercial paper, may receive at least 5% of the net proceeds of this offering, after deducting underwriting discounts and estimated offering expenses payable by us. Because 5% or more of the net proceeds of this offering may be paid to any underwriter and its affiliates, which is considered a “conflict of interest” under Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5121, this offering will be made in accordance with the applicable requirements of FINRA Rule 5121 regarding the underwriting of securities of a company with a member that has a conflict of interest within the meaning of those rules. Pursuant to FINRA Rule 5121(a)(1)(C), the appointment of a qualified independent underwriter is not necessary in connection with this offering because the notes offered pursuant to this prospectus supplement are investment grade rated under the requirements of paragraph (f)(8) of FINRA Rule 5121. In accordance with FINRA Rule 5121(c), no sales of the notes will be made to any discretionary account over which any underwriter with a conflict of interest exercises discretion without the prior specific approval of the account holder. See “Underwriting (Conflicts of Interest).”

Denominations

The notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Form of Notes

The notes will be issued as fully registered notes, represented by one or more global notes registered in the name of Cede & Co., the nominee of the depositary, The Depository Trust Company (“DTC”). Beneficial interests in the notes will be shown on, and transfers will be effected through, records maintained by DTC and its participants. See “Global Securities” in the accompanying prospectus.

RISK FACTORS

Investing in the notes involves risks. In considering whether to purchase the notes, you should carefully consider all of the information set forth in this prospectus supplement, the accompanying prospectus, any free writing prospectus with respect to this offering filed by us with the SEC and the documents incorporated by reference herein and therein. In particular, you should carefully consider the specific risks described below in addition to the risks described under the heading “Item 1A. Risk Factors” contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which is incorporated by reference herein. You could lose part or all of your investment.

The risks and uncertainties discussed in this prospectus supplement and in the documents incorporated by reference herein are those we currently believe may materially affect us. Additional risks and uncertainties not presently known to us or that we currently believe are immaterial also may materially and adversely affect our business, financial condition and results of operations.

Your ability to transfer the notes may be limited since there is no public market for the notes, and we do not know if an active trading market will ever develop, or if a market does develop, whether it will be sustained.

The notes will constitute a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or quotation of the notes on any automated dealer quotation system. We cannot assure you as to the development or liquidity of any trading market for the notes. The underwriters have advised us that they currently intend to make a market in the notes, as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and any market-making with respect to the notes may be discontinued at any time without notice. If no active trading market develops, you may be unable to resell your notes at any price or at their fair market value.

If a trading market does develop, changes in our credit ratings or the debt markets could adversely affect the liquidity of any market for the notes.

The liquidity of any market for the notes will depend on a number of factors, including:

•

our credit ratings with major credit rating agencies;

•

the prevailing interest rates being paid by other companies similar to us;

•

the market price of our common shares;

•

our financial condition, operating performance and future prospects;

•

the market for similar securities;

•

the overall condition of the financial markets; and

•

the interest of securities dealers in making a market for the notes.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future. Such fluctuations could have an adverse effect on the price of the notes.

In addition, credit rating agencies continually review their ratings for the companies that they follow, including us. The credit rating agencies also evaluate the industries in which we operate as a whole and may change their credit rating for us based on their overall view of such industries. A negative change in our rating could have an adverse effect on the price of the notes. Therefore, we cannot assure you that you will be able to sell your notes at a particular time or the price that you receive when you sell your notes will be favorable.

Despite our current or future indebtedness level, we may still be able to incur substantially more debt.

We may be able to incur substantial indebtedness in the future. The terms of the indenture governing the notes do not prohibit us from doing so. If we incur any additional indebtedness that ranks equally with the notes, the holders of that debt will be entitled to share ratably with the holders of the notes in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding up of the Company.

S-6

Table of Contents

Our debt instruments contain restrictive covenants that may adversely affect our ability to operate our business.

The credit agreements governing our Revolving Loans and the Term Loans, the indenture that will govern the notes and the note purchase agreements which govern our existing notes contain various covenants that limit our ability and the ability of our subsidiaries to, among other things:

•

incur certain liens;

•

enter into certain sale and leaseback transactions with respect to any of our Principal Property (as defined under “Description of the Notes”);

•

consolidate or merge with or into, or sell all or substantially all of our assets to, another person;

•

make accounting changes, except as required or permitted under generally accepted accounting principles;

•

make a material change to the nature of our business;

•

engage in speculative transactions; and

•

incur additional indebtedness and guarantee indebtedness.

In addition, the credit agreements governing our Revolving Loans and Term Loans and the note purchase agreements governing our existing notes contain financial maintenance covenants limiting the ratio of debt to earnings before interest, taxes, depreciation and amortization. Although we were in compliance with the financial maintenance covenant under such agreements as of September 30, 2026, the ability to meet each financial maintenance covenant can be affected by events beyond our control, and we cannot provide assurance that we will continue to meet these tests. A breach of certain covenants under the Financing Agreements could also result in a default under our other indebtedness. Upon the occurrence of an event of default under any of our indebtedness, the lenders could elect to declare all amounts outstanding thereunder to be immediately due and payable and terminate all commitments to extend further credit. If the lenders accelerate the repayment of borrowings, we may not have sufficient assets to repay our Revolving Loans, Term Loans and other indebtedness, including these notes.

We may be unable to generate the cash flow to service our debt obligations, including the notes.

We cannot assure you that our business will generate sufficient cash flow, or that we will be able to borrow funds under our Revolving Credit Agreement, in an amount sufficient to enable us to service our indebtedness, including the notes, or to make anticipated capital expenditures. Our ability to pay our expenses and satisfy our debt obligations, to refinance our debt obligations and to fund planned capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. If we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the notes) or obtain additional financing. We cannot assure you that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, if at all. Additionally, the covenants contained in our Financing Agreements restrict our ability to incur additional debt.

We may not be able to repurchase the notes upon a Change of Control Repurchase Event.

Upon the occurrence of a “Change of Control Repurchase Event” (as described under “Description of the Notes — Change of Control” in this prospectus supplement), we will be required to offer to repurchase all of the outstanding notes offered hereby at a purchase price in cash equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of holders of record on the relevant interest record date to receive interest due on the relevant interest payment date). However, we may not be able to repurchase the notes upon a Change of Control Repurchase Event because we may not have sufficient funds to do so. In addition, our future debt agreements may contain provisions that restrict us from repurchasing all of the notes tendered by holders upon a Change of Control Repurchase Event. Our failure to repurchase the notes upon a Change of

S-7

Table of Contents

Control Repurchase Event would cause a default under the indenture that will govern the notes, which could result in defaults under our other debt agreements and have material adverse consequences for us and the holders of the notes.

Redemption may adversely affect your return on the notes.

We have the right to redeem some or all of the notes prior to maturity, as described under “Description of the Notes — Optional Redemption” in this prospectus supplement. We may redeem the notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate of the notes being redeemed.

The notes will be effectively subordinated in right of payment to any future secured indebtedness to the extent of the assets securing such indebtedness.

The notes will be unsecured and effectively subordinated in right of payment to any future secured indebtedness to the extent of the assets securing such indebtedness. Although the indenture limits our ability to incur liens on our Principal Property (as defined under “Description of the Notes”), the notes will be effectively subordinated to any future debt secured by Principal Property to the extent permitted by the indenture or secured by any of our other assets. In the event of our liquidation or insolvency or other events of default on any such secured debt or upon acceleration of the notes in accordance with their terms, we will be permitted to make payment on the notes only after any such secured debt has been paid in full. After paying any such secured debt in full, we may not have sufficient assets remaining to pay any or all amounts due on the notes. In the event of our bankruptcy, liquidation or reorganization or upon acceleration of the notes, payment on the notes could be less, ratably, than on any such secured debt.

The notes will be effectively subordinated to any indebtedness of our subsidiaries.

The notes will be effectively subordinated to any indebtedness of our subsidiaries. Our subsidiaries are separate and distinct legal entities, and none of our subsidiaries will guarantee the notes or otherwise have any obligations to make payments in respect of the notes. As a result, claims of holders of the notes will be effectively subordinated to the indebtedness and other liabilities of our subsidiaries. In the event of any bankruptcy, liquidation, dissolution or similar proceeding involving one of our subsidiaries, any of our rights or the rights of the holders of the notes to participate in the assets of that subsidiary will be effectively subordinated to the claims of creditors of that subsidiary, and following payment by that subsidiary of its liabilities, the subsidiary may not have sufficient assets remaining to make payments to us as a shareholder or otherwise. As of September 30, 2026, our subsidiaries had approximately $16,000 of indebtedness to which the notes would have been effectively subordinated.

Our cash flow and our ability to service our indebtedness, including the notes, are partially dependent upon the earnings of our subsidiaries.

The notes are exclusively our obligations. Our cash flow and our ability to service our indebtedness, including the notes, are partially dependent upon the earnings of our subsidiaries. In addition, we are particularly dependent on the distribution of earnings, loans or other payments by our subsidiaries to us.

Our subsidiaries are separate and distinct legal entities. Our subsidiaries will have no obligation to pay any amounts due on the notes or to provide us with funds for our payment obligations, whether by dividends, distributions, loans or other payments. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to statutory or contractual restrictions. Payments to us by our subsidiaries will also be contingent upon our subsidiaries’ earnings and business considerations. Our right to receive any assets of any subsidiary upon its liquidation or reorganization, and, therefore, our right to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. In addition, even if we were a creditor of any of our subsidiaries, our right as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to the indebtedness held by us.

USE OF PROCEEDS

We anticipate that the net proceeds to us from the sale of the notes, after deducting the underwriting discount and estimated offering expenses payable by us, will be approximately $ million. We intend to use the net proceeds from this offering, together with the net proceeds from the Concurrent Securities Offerings, to repay all or a portion of the outstanding borrowings under the Financing Agreements and/or our outstanding commercial paper obligations, and for general corporate purposes.

The borrowings under our Revolving Credit Agreement mature in June 2031 and bear interest at a benchmark interest rate applicable to each Agreed Currency (as defined in the Revolving Credit Agreement) plus an applicable margin that ranges from 0.68% to 1.10% based on, at our election, our credit rating or, prior to a Financial Covenant Transition Date (as defined in the Revolving Credit Agreement), our net leverage ratio. As of October 30, 2026, the weighted average interest rate on the borrowings outstanding on the Revolving Credit Agreement was 3.15%.

The borrowings under our Term Loan Agreement mature on August 26, 2029 for Tranche A Loans, August 26, 2030 for Tranche B Loans, and August 26, 2031 for Tranche C Loans. Tranche A Loans bear interest at a secured overnight financing rate plus an applicable margin that ranges from 0.875% to 1.375%, Tranche B Loans bear interest at a secured overnight financing rate plus an applicable margin that ranges from 1.000% to 1.500%, and Tranche C Loans bear interest at a secured overnight financing rate plus an applicable margin that ranges from 1.250% to 1.750%, all based on, at our election, our credit rating or, prior to a Financial Covenant Transition Date (as defined in the Term Loan Agreement), our net leverage ratio. As of October 30, 2026, the weighted average interest rate on the borrowings outstanding on the Term Loan Agreement was 5.05%.

The borrowings under our commercial paper facility have varying maturities, but may not exceed 364 days from the date of issue. Our commercial paper is sold under customary terms in the commercial paper market, and bears varying interest rates. As of October 30, 2026, the amount of commercial paper outstanding was $280 million with a weighted-average maturity of approximately 14 days and a weighted-average interest rate of 4.20%.

Certain of the underwriters and/or their affiliates are acting as lenders under our Financing Agreements and own our commercial paper, and as a result, may receive a portion of the proceeds from this offering. See “Underwriting (Conflicts of Interest).”

DESCRIPTION OF THE NOTES

The following description of the notes should be read together with the description set forth in the accompanying prospectus under the heading “Description of Debt Securities.” In the event that information in this prospectus supplement is inconsistent with information in the accompanying prospectus, you should rely on this prospectus supplement.

The description of the notes in this prospectus supplement and the accompanying prospectus is only a summary and is intended to be a useful overview of the material provisions of the notes and the indenture, but is not intended to be comprehensive. Since this description of the notes is only a summary, you should refer to the indenture for a complete description of our obligations and your rights thereunder. We have filed a copy of the indenture as an exhibit to the registration statement of which the accompanying prospectus is a part.

The notes are a series of “senior debt securities” as described in the accompanying prospectus. We will issue the notes under an indenture, dated as of November 10, 2026 (as such indenture has been and may be amended from time to time, the “indenture”), between us and U.S. Bank Trust Company, National Association, as trustee. The terms of the notes include those expressly set forth in the indenture and those made part of the indenture by referencing the Trust Indenture Act of 1939, as amended.

We may, without notice to, or the consent of, the registered holders of the notes, issue an unlimited principal amount of additional notes having identical terms and conditions as the notes, other than, in each case, the issue date, issue price and, in some cases, the first interest payment date. We will only be permitted to issue such additional notes if, at the time of such issuance, we are in compliance with the covenants contained in the indenture. Any additional notes will be part of the same issue as the notes offered hereby and will vote on all matters with the holders of the notes, provided that if such additional notes are not fungible for U.S. federal income tax purposes with the notes offered hereby, such additional notes will be issued with a separate CUSIP number.

When we refer to “we,” “us” or “our” in this section, we refer only to AMETEK, Inc., the issuer of the notes, and not to its subsidiaries. Unless otherwise defined in this section below, capitalized terms used in this “Description of the Notes” section are defined under “Description of Debt Securities — Definitions” in the accompanying prospectus.

General

The notes will be initially limited to $ aggregate principal amount in this offering; however, we may issue additional notes at a later time that will be part of the same issue as the notes offered hereby as described above. The notes will mature on , 20 , unless earlier redeemed by us, and upon surrender will be repaid at 100% of the principal amount thereof.

The notes will be issued only in fully registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. Principal of and premium, if any, and interest on the notes are payable in immediately available funds in U.S. dollars, or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

Principal of and premium, if any, and interest on the notes will be payable, and the notes may be exchanged or transferred, at our office or agency in New York (which initially shall be the corporate trust office of the trustee, at U.S. Bank Trust Company, National Association, 100 Wall Street, New York, NY 10005), except that, at our option, payment of interest may be made by check mailed to the registered holders of the notes at their registered addresses. No service charge will be made for any registration of transfer or exchange of notes, but we or the trustee may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge payable in connection with such transfer or exchange.

In any case where the date of payment of the principal of or premium, if any, or interest on the notes, including the date, if any, fixed for redemption or repurchase of the notes, shall not be a “business day” (as defined below), then payment of principal, premium or interest need not be made on that date at such place but may be made on the next succeeding business day, with the same force and effect as if made on the applicable payment date or the date fixed for redemption or repurchase, and no interest shall accrue for the

S-11

Table of Contents

period after that date. A “business day” shall mean a day that is not, in New York, a Saturday, Sunday, a legal holiday or a day on which banking institutions are authorized or obligated by law to close.

The Notes

The notes will bear interest at the rate of % per annum. The notes will accrue interest on their principal amount from , 2026 or from the most recent interest payment date on which interest has been paid or provided for. Interest on the notes shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. Interest on the notes will be payable semi-annually on and of each year, beginning on , 20 (each such date is referred to as an “interest payment date”), until the principal amount has been paid or made available for payment, to holders of the notes at the close of business on or , immediately preceding the applicable interest payment date (each such date is referred to as an “interest record date”).

Optional Redemption

Prior to the Par Call Date (as defined below), we may redeem the notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points, less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but not including, the applicable redemption date.

On or after the Par Call Date, we may redeem the notes, at our option, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed, respectively, plus accrued and unpaid interest thereon to, but not including, the redemption date.

For purposes of this “— Optional Redemption” section, the following terms have the following meanings:

“Par Call Date” means , 20 ( months prior to the maturity date).

“Treasury Rate” means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate applicable to the notes shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph,

S-12

Table of Contents

the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, we shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed.

In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by DTC (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the depositary.

Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

Except as described above, the notes will not be redeemable by us prior to maturity and will not be entitled to the benefit of any sinking fund.

We may acquire notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the indenture.

The trustee, the calculation agent and the paying agent shall not be responsible for performing or verifying any calculations required in connection with a redemption.

Ranking

The notes will be senior unsecured and unsubordinated indebtedness and will rank equally with all of our existing and future senior unsecured and unsubordinated indebtedness. However, the notes are effectively subordinated to the indebtedness of our subsidiaries and effectively subordinated to any future secured indebtedness to the extent of the value of the assets securing such indebtedness. As of September 30, 2026 on a pro forma as adjusted basis after giving effect to this offering and the application of the net proceeds from this offering and the Concurrent Securities Offerings as more fully described in “Use of Proceeds” in this prospectus supplement:

S-13

Table of Contents

•

we would have had approximately $ billion of unsecured and unsubordinated indebtedness (including the Euro notes, Canadian dollar notes and the notes), all of which would constitute senior indebtedness; we would have no secured indebtedness to which the notes would have been effectively subordinated; and

•

our subsidiaries would have had approximately $16,000 of indebtedness to which the notes would have been effectively subordinated.

We are obligated to pay compensation to the trustee and to indemnify the trustee against certain losses, liabilities and expenses incurred by the trustee in connection with its duties relating to the notes. The trustee’s claims for these payments will generally be senior to those of holders of the notes in respect of all funds collected or held by the trustee.

Change of Control

If a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem all of the notes as described under “— Optional Redemption” above, each holder will have the right to require us to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such holder’s notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price in cash equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of holders of record on the relevant interest record date to receive interest due on the relevant interest payment date).

Within 30 days following any Change of Control Repurchase Event, or at our option, prior to any Change of Control but after the public announcement of the pending Change of Control, we will send, by first class mail, a notice to each holder, with a copy to the trustee, which notice will govern the terms of the Change of Control Offer, stating:

(i) that such Change of Control Repurchase Event has occurred or is pending and that such holder has the right to require us to repurchase such holder’s notes at a purchase price in cash equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of holders of record on the relevant interest record date to receive interest due on the relevant interest payment date) (the “Change of Control Payment”);

(ii) if such notice is mailed prior to the date of consummation of the Change of Control, that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date;

(iii) the date of repurchase (which shall be no earlier than 30 days nor later than 60 days from the date the Change of Control Offer is mailed) (the “Change of Control Payment Date”); and

(iv) the procedures determined by us, consistent with the indenture, that a holder must follow in order to have its notes repurchased.

On the Change of Control Payment Date, we will, to the extent lawful:

(a) accept for payment all notes or portions of notes (equal to $2,000 and integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer;

S-14

Table of Contents

(b) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes so tendered; and

(c) deliver or cause to be delivered to the trustee the notes so accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being repurchased by us and, to the extent applicable, an executed new note or notes evidencing any unpurchased portion of any note or notes surrendered for which the trustee shall authenticate and deliver a new note or notes as provided below.

The trustee will as promptly as practicable mail, or cause the paying agent to promptly mail, to each holder of notes so tendered, the Change of Control Payment for such notes, and the trustee will as promptly as practicable authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any, provided that each such new note will be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the person in whose name a note is registered at the close of business on such interest record date, and no additional interest will be payable to holders who tender pursuant to the Change of Control Offer.

Except as described above with respect to a Change of Control Repurchase Event, the indenture does not contain provisions that permit the holders to require us to repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

We will not be required to make the Change of Control Offer upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to the Change of Control Offer made by us and repurchases all notes validly tendered and not withdrawn under such offer.

We will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.

Our ability to repurchase notes pursuant to the Change of Control Offer may be limited by a number of factors. Certain events that may constitute a change of control under our other senior indebtedness and indebtedness of our subsidiaries and cause a default under the agreements related to such indebtedness may not constitute a Change of Control Repurchase Event under the indenture. Our Financing Agreements provide that the occurrence of certain change of control events would constitute a default thereunder. Future indebtedness of ours and our subsidiaries may also contain prohibitions of certain events that would constitute a Change of Control Repurchase Event or require such indebtedness to be repurchased upon a Change of Control Repurchase Event. Moreover, any exercise by the holders of our outstanding senior notes of their right to require us to repurchase their notes could cause a default under such indebtedness, even if a Change of Control Repurchase Event itself does not, due to the financial effect of such repurchases on us. Finally, our ability to pay cash to the holders upon a repurchase may be limited by our then existing financial resources. We cannot assure you that sufficient funds will be available when necessary to make any required repurchases. See “Risk Factors — We may not be able to repurchase the notes upon a Change of Control Repurchase Event.”

Even if sufficient funds were otherwise available, the terms of our future indebtedness may prohibit our prepayment of the notes before their scheduled maturity. Consequently, if we are not able to prepay our senior indebtedness and any such other indebtedness containing similar restrictions or obtain requisite consents, we will not be able to fulfill our repurchase obligations if holders of notes exercise their repurchase rights following a Change of Control Repurchase Event, resulting in a default under the indenture. A default under the indenture may result in a cross-default under our other senior indebtedness, including under our Financing Agreements.

The Change of Control Repurchase Event provisions described above may deter certain mergers, tender offers and other takeover attempts involving us by increasing the capital required to effectuate such transactions. The definition of “Change of Control” below includes a disposition of all or substantially all of our property and assets and our subsidiaries taken as a whole to any person. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of “all or substantially all” of the property or assets of a person. As a result, it may be unclear as to whether or not a Change of Control, and thus a Change of Control Repurchase Event, has occurred and whether or not a holder of notes may require us to make an offer to repurchase the notes as described above. The provisions under the indenture relative to our obligation to make an offer to repurchase the notes as a result of a Change of Control Repurchase Event may be waived or modified with the written consent of the holders of a majority in principal amount of the outstanding notes.

For purposes of this “— Change of Control” section, the following terms have the following meanings:

“Change of Control” means:

(a) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any “person” (as such term is used in Sections 13(d)(3) of the Exchange Act) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that such person shall be deemed to have “beneficial ownership” of all shares that any such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 50% of the total voting power of our Voting Stock (or our successor by merger, consolidation or purchase of all or substantially all of our assets) (for the purposes of this clause, such person shall be deemed to beneficially own any of our Voting Stock held by a parent entity, if such person “beneficially owns” (as defined above), directly or indirectly, more than a majority of the voting power of the Voting Stock of such parent entity); or

(b) we consolidate with, or merge with or into, any person, or any person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of our outstanding Voting Stock or outstanding Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of our Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person immediately after giving effect to such transaction;

(c) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our assets and the assets of the subsidiaries taken as a whole to any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than to us or one of our subsidiaries; or

(d) the adoption by our stockholders of a plan or proposal for our liquidation or dissolution.

Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (a) we become a direct or indirect wholly owned subsidiary of a holding company and (b) immediately following that transaction, (1) the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (2) no person or group is the beneficial owner, directly or indirectly, of more than a majority of the total voting power of the Voting Stock of the holding company.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Rating Decline with respect to such Change of Control. Notwithstanding anything in this “— Change of Control” section, no Change of Control Repurchase Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Investment Grade” means BBB− or higher by S&P and Baa3 or higher by Moody’s, or the equivalent of such ratings by S&P or Moody’s or, if either S&P or Moody’s shall not make a rating on the notes publicly available, another Rating Agency.

S-16

Table of Contents

“Moody’s” means Moody’s Investors Service Inc. and its successors.

“Rating Agency” means each of S&P and Moody’s or, to the extent S&P or Moody’s or both do not make a rating on the notes publicly available, a “nationally recognized statistical rating organization” (within the meaning of Section 3(a)(62) under the Exchange Act) or “organizations,” as the case may be, selected by us (as certified by a resolution of our board of directors), which shall be substituted for S&P or Moody’s, or both, as the case may be.

“Rating Decline” means, with respect to a Change of Control, the notes cease to be rated Investment Grade by each Rating Agency on any date during the period (“Trigger Period”) from the date of the public notice of an arrangement that could result in such Change of Control until 60 days following the consummation of such Change of Control (which Trigger Period will be extended for so long as the rating on the notes is under publicly announced consideration for a possible downgrade by either of the Rating Agencies).

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors.

“Voting Stock” of any specified person as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors, managers or trustees, as applicable, of such person.

Reporting

As set forth in the indenture, we will be required, so long as any of the notes are outstanding, to file with the trustee (electronically or in hard copy), within 15 days after we file the same with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) that we may be required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act; or, if we are not required to file information, documents or reports pursuant to either of such Sections, then we will file with the trustee and the SEC, in accordance with the rules and regulations prescribed from time to time by the SEC, such supplementary and periodic information, documents and reports that may be required pursuant to Section 13 of the Exchange Act in respect of a security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations. We will be deemed to have furnished such information, documents and reports to holders if we have filed such information, documents and reports with the SEC using the EDGAR filing system and such information, documents and reports are publicly available via EDGAR.

Events of Default

In addition to those set forth under “Description of Debt Securities — Events of Default” in the accompanying prospectus, the following is an “event of default” under the indenture with respect to the debt securities:

(1) a failure to make any payment at maturity, including any applicable grace period, on any of our indebtedness (other than indebtedness of ours owing to any of its subsidiaries) outstanding in an amount in excess of $250 million or its foreign currency equivalent at the time and continuance of this failure to pay or (2) a default on any of our indebtedness (other than indebtedness owing to any of our subsidiaries), which default results in the acceleration of such indebtedness in an amount in excess of $250 million or its foreign currency equivalent at the time without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (1) or (2) above; provided, however, that if any failure, default or acceleration referred to in clauses (1) or (2) above ceases or is cured, waived, rescinded or annulled, then the event of default under the indenture will be deemed cured.

Certain Covenants

In addition to those set forth under “Description of Debt Securities — Certain Covenants” in the accompanying prospectus, the indenture contains various covenants, including, among others, the following:

S-17

Table of Contents

Limitation on Liens

So long as the senior debt securities are outstanding under the indenture, neither we nor any Restricted Subsidiary will, directly or indirectly, issue, incur, create, assume or guarantee any indebtedness secured by a mortgage, security interest, pledge, lien, charge or other encumbrance upon any Principal Property or upon any shares of capital stock or indebtedness of any Restricted Subsidiary (a “mortgage”), whether such Principal Property, shares or indebtedness are now existing or owned or hereafter created or acquired, unless prior to or at the same time the senior debt securities are equally and ratably secured with or, at our option, prior to such secured indebtedness.

This restriction does not apply to

•

mortgages on property, shares of capital stock or indebtedness or other assets of any entity existing at the time such entity becomes a Restricted Subsidiary, provided that such mortgage was not incurred in anticipation of such entity becoming a Restricted Subsidiary;

•

mortgages on property, shares of capital stock, indebtedness or other assets existing at the time of acquisition by us or any Restricted Subsidiary (which may include property previously leased by us and leasehold interests on the property, provided that the lease terminates prior to or upon the acquisition), provided that such mortgage was not incurred in anticipation of such acquisition;

•

mortgages on property, shares of capital stock, indebtedness or other assets to secure any indebtedness incurred prior to, at the time of, or within 270 days after, the latest of the acquisition of such property, shares of capital stock or indebtedness, or in the case of real property, the completion of construction, the completion of improvements or the beginning of substantial commercial operation of such real property for the purpose of financing all or any part of the purchase price of such real property, the construction thereof or the making of improvements thereto;

•

mortgages in favor of us or another Restricted Subsidiary;

•

mortgages existing at the time of the closing of the offering of the senior debt securities;

•

mortgages on property or other assets of any entity existing at the time such entity is merged into or consolidated with either us or any Restricted Subsidiary or at the time of a sale, lease or other disposition of the properties of such entity as an entirety or substantially as an entirety to either us or any Restricted Subsidiary, provided that this mortgage was not incurred in anticipation of the merger or consolidation or sale, lease or other disposition;

•

mortgages in favor of the United States of America or any state, territory or possession thereof (or the District of Columbia) to secure partial, progress, advance or other payments pursuant to any contract or statute or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or cost of constructing or improving the property subject to such mortgages;

•

mortgages created in connection with a project financed with, and created to secure, a Nonrecourse Obligation;

•

mortgages securing all of the senior debt securities outstanding under the indenture;

•

mortgages on accounts receivable securing our indebtedness; or

•

extensions, renewals or replacements of any mortgage referred to above without increase of the principal of the indebtedness secured by the mortgage;

provided, however, that any mortgages permitted by any of the clauses above shall not extend to or cover any property of ours or that of any Restricted Subsidiary, as the case may be, other than the property specified in these clauses and improvements to this property.

Notwithstanding the restrictions outlined in the preceding paragraphs, we and any Restricted Subsidiary are permitted to issue, incur, create, assume or guarantee indebtedness secured by a mortgage without equally and ratably securing the senior debt securities then outstanding under the indenture, if, after giving effect thereto and any concurrent retirement of indebtedness, the aggregate amount of all indebtedness secured by mortgages (not including mortgages permitted under the above) does not at such time exceed 15% of Consolidated Net Tangible Assets at such time.

S-18

Table of Contents

Notwithstanding the foregoing, any mortgage securing the senior debt securities granted pursuant to this covenant shall be automatically and unconditionally released and discharged upon the release by all holders of the indebtedness secured by the mortgage giving rise to the mortgage securing the senior secured securities (including any deemed release upon payment in full of all obligations under such indebtedness).

Limitation on Sale and Leaseback Transactions

So long as the senior debt securities are outstanding under the indenture, neither we nor any Restricted Subsidiary will enter into any “sale/leaseback transaction” (as defined below) with respect to any Principal Property, whether now owned or hereafter acquired by us or any Restricted Subsidiary, unless:

(a)

we or such Restricted Subsidiary would, at the time of entering into such arrangement, be able to incur indebtedness secured by a mortgage on the Principal Property involved in the transaction at least equal in amount to the Attributable Debt with respect to such sale/leaseback transaction, without equally and ratably securing the senior debt securities under the covenant described in “— Limitation on Liens” above; or

(b)

the net proceeds of the sale of the Principal Property to be leased are at least equal to such Principal Property’s fair market value, as determined by our board of directors or as established or affirmed by a nationally recognized independent third-party valuation firm, and the proceeds are applied within 180 days of the effective date of the sale/leaseback transaction to the purchase, construction, development or acquisition of assets that are Principal Property or to the repayment of senior indebtedness of us or any Restricted Subsidiary.

This restriction does not apply to sale/leaseback transactions:

•

entered into prior to the time of the closing of the offering of the senior debt securities;

•

between us and any Restricted Subsidiary or between Restricted Subsidiaries;

•

under which the rent payable pursuant to such lease is to be reimbursed under a contract with the U.S. Government or any instrumentality or agency thereof;

•

involving leases for a period of no longer than three years; or

•

in which the lease for the property or asset is entered into within 270 days after the date of acquisition, completion of construction or commencement of full operations of such property or asset, whichever is latest.

For purposes of this “— Limitation on Sale and Leaseback Transactions” section, the following terms have the following meanings:

A “sale/leaseback transaction” means an arrangement relating to property now owned or hereafter acquired whereby either we transfer, or any Restricted Subsidiary transfers, such property to a person and either we or any Restricted Subsidiary leases it back from such person.

Notwithstanding the restrictions outlined in the preceding paragraphs, we and any Restricted Subsidiary will be permitted to enter into sale/leaseback transactions that would otherwise be subject to such restrictions, without complying with the requirements of clauses (a) and (b) above, if, after giving effect thereto, the aggregate amount of all Attributable Debt with respect to sale/leaseback transactions existing at such time that could not have been entered into except for the provisions described in this paragraph, together with the aggregate amount of all outstanding indebtedness secured by mortgages permitted by any of the bullets under “— Limitation on Liens” above, does not exceed 15% of Consolidated Net Tangible Assets at such time.

A sale/leaseback transaction shall not be deemed to result in the creation of a mortgage.

“Attributable Debt” means, when used in connection with a sale/leaseback transaction, on any date as of which the amount of Attributable Debt is to be determined, the product of (a) the net proceeds from the sale/leaseback transaction multiplied by (b) a fraction, the numerator of which is the number of full years of the term of the lease relating to the property involved in the sale/leaseback transaction (without regard to

S-19

Table of Contents

any options to renew or extend such term) remaining on the date of the making of the computation, and the denominator of which is the number of full years of the term of the lease measured from the first day of the term.

“Consolidated Net Tangible Assets” means, as of the date of determination, the aggregate amount of assets included on AMETEK’s consolidated balance sheet as of the most recent fiscal quarter end for which such consolidated balance sheet is available, minus (a) all current liabilities, except for current maturities of long-term debt and current maturities of obligations under capital leases, and (b) total goodwill and other intangible assets, all as set forth on the most recent consolidated balance sheet of AMETEK and its consolidated subsidiaries and computed in accordance with generally accepted accounting principles.

“indebtedness” means, with respect to any person, obligations (other than Nonrecourse Obligations) of such person for borrowed money or evidenced by bonds, debentures, notes or similar instruments.

“Nonrecourse Obligation” means indebtedness or other obligations substantially related to (a) the acquisition of assets not previously owned by us or any Restricted Subsidiary or (b) the financing of a project involving the development or expansion of our properties or those of any Restricted Subsidiary, as to which the obligee with respect to such indebtedness or obligation has no recourse to us or any Restricted Subsidiary or any of our assets or those of any Restricted Subsidiary other than the assets that were acquired with the proceeds of such transaction or the project financed with the proceeds of such transaction (and the proceeds thereof).

“Principal Property” means the land, land improvements, buildings (to the extent they constitute real property interests and including any leasehold interest therein) and fixtures (including, for the avoidance of doubt, all machinery and equipment) constituting the principal corporate office, any manufacturing plant, any manufacturing facility or any warehouse (whether now owned or hereafter acquired), the net book value of which on the date the determination is being made is an amount which exceeds the greater of 1% of Consolidated Net Tangible Assets and $50 million, that (1) is owned by us or any of our subsidiaries and (2) is located within any of the present 50 states of the United States of America (or the District of Columbia), unless our board of directors has determined in good faith that such property is not materially important to the total business conducted by us and our subsidiaries, taken as a whole.

“Restricted Subsidiary” means any of our direct or indirect subsidiaries that owns any Principal Property; provided, however, that the term “Restricted Subsidiary” does not include:

•

any such subsidiary that is principally engaged in leasing or in financing receivables or that is principally engaged in financing outside the United States of America our operations or those of our subsidiaries; or

•

any such subsidiary less than 80% of the Voting Stock of which is owned, directly or indirectly, by us, by one or more of our other subsidiaries or by us and one or more of our other subsidiaries if the common stock of such subsidiary is traded on any national securities exchange or in the over-the-counter market.

“Voting Stock” of a person means all classes of any and all shares, interests, rights to purchase, warrants, options, participation or other equivalents of or interests in (however designated) equity of such person, including any preferred stock and limited liability or partnership interests (whether general or limited), but excluding any debt securities convertible into such equity, to the extent then outstanding and normally entitled to vote in the election of such person’s directors, managers or trustees, as applicable.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of the material U.S. federal income tax consequences relevant to the purchase, ownership and disposition of the notes issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or foreign tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a holder of the notes. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of the notes.

This discussion is limited to holders who hold the notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). In addition, this discussion is limited to persons purchasing the notes for cash at original issue and at their original “issue price” within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the notes is sold to the public for cash).

This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons subject to any alternative minimum tax;

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to the notes being taken into account in an applicable financial statement;

•

U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

•

persons holding the notes as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•

banks, insurance companies, and other financial institutions;

•

real estate investment trusts or regulated investment companies;

•

brokers, dealers or traders in securities;

•

“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

holders of any of our indebtedness that is repaid or repurchased substantially simultaneously with this offering;

•

S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

•

tax-exempt organizations or governmental organizations; and

•

persons deemed to sell the notes under the constructive sale provisions of the Code.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding the notes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE

Table of Contents

APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS (INCLUDING ESTATE AND GIFT TAX LAWS), UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Tax Considerations Applicable to U.S. Holders

Definition of a U.S. Holder

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of a note that, for U.S. federal income tax purposes, is or is treated as:

•

an individual who is a citizen or resident of the United States;

•

a corporation created or organized under the laws of the United States, any state thereof, or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Additional Payments

In certain circumstances (see “Description of the Notes — Optional Redemption” and “Description of the Notes — Change of Control”), we may be obligated to redeem or repurchase the notes prior to their scheduled maturity and/or to pay amounts in excess of stated interest or principal on the notes. We intend to take the position that the possibility of such redemption or repurchase or such payments does not result in the notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. Such position is not binding on the IRS. If the IRS successfully challenged this position, and the notes were treated as contingent payment debt instruments, U.S. Holders of the notes could be required to accrue interest income at a rate higher than the stated interest rate on the notes, regardless of the holder’s method of accounting, and to treat as ordinary income, rather than capital gain, any gain recognized on a sale, exchange, redemption, retirement, or other taxable disposition of a note. Prospective investors should consult their tax advisors regarding the tax consequences if the notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that no notes are treated as contingent payment debt instruments.

Payments of Interest

Interest on a note generally will be taxable to a U.S. Holder as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder’s method of tax accounting for U.S. federal income tax purposes. It is expected, and this discussion assumes, that the notes will be issued with no more than a de minimis amount of original issue discount for U.S. federal income tax purposes.

Sale or Other Taxable Disposition

A U.S. Holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note. The amount of such gain or loss will generally equal the difference between the amount received for the note in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which will be taxable as interest to the extent not previously included in income as described above under “Payments of Interest”) and the U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note generally will be equal to the amount the U.S. Holder paid for the note. Any gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has held the note for more than one year at the time of sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain

S-22

Table of Contents

non-corporate U.S. Holders, including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

A U.S. Holder may be subject to information reporting and backup withholding when such holder receives payments on a note or receives proceeds from the sale or other taxable disposition of a note (including a redemption or retirement of a note). Certain U.S. Holders are exempt from backup withholding, including corporations and certain tax-exempt organizations. A U.S. Holder will generally be subject to backup withholding if such holder is not otherwise exempt and:

•

the holder fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number;

•

the holder furnishes an incorrect taxpayer identification number;

•

the applicable withholding agent is notified by the IRS that the holder previously failed to properly report payments of interest or dividends; or

•

the holder fails to certify under penalties of perjury that the holder has furnished a correct taxpayer identification number and that the IRS has not notified the holder that the holder is subject to backup withholding or the IRS has notified the holder that the holder is no longer subject to backup withholding.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Tax Considerations Applicable to Non-U.S. Holders

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of a note that is neither a U.S. Holder nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

Payments of Interest

Subject to the discussions below on backup withholding and FATCA withholding, interest paid on a note to a Non-U.S. Holder that is not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States generally will not be subject to U.S. federal income tax or withholding tax, provided that:

•

the Non-U.S. Holder does not, actually or constructively, own 10% or more of the total combined voting power of all classes of our voting stock;

•

the Non-U.S. Holder is not a controlled foreign corporation related to us through actual or constructive stock ownership; and

•

the Non-U.S. Holder certifies in a statement provided to the applicable withholding agent that it is not a United States person (generally by providing a properly executed IRS Form W-8BEN or W-8BEN-E, as applicable).

If a Non-U.S. Holder does not satisfy the requirements above, interest paid on a note to such Non-U.S. Holder generally will be subject to a 30% U.S. federal withholding tax. However, such Non-U.S. Holder may be entitled to a reduction in or an exemption from withholding on such interest as a result of an applicable tax treaty. To claim such entitlement, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming a reduction in or exemption from withholding tax under the benefit of an income tax treaty between the United States and the country in which the Non-U.S. Holder resides or is established.

S-23

Table of Contents

If interest paid to a Non-U.S. Holder is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such interest is attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI (or other applicable documentation), certifying that interest paid on a note is not subject to withholding tax because it is effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States.

Any such effectively connected interest generally will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to United States persons. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected interest, as adjusted for certain items.

The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and may be required to be updated periodically. Non-U.S. Holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Sale or Other Taxable Disposition

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale, exchange, redemption, retirement or other taxable disposition of a note (such amount excludes any amount allocable to accrued and unpaid interest, which generally will be treated as interest and may be subject to the rules discussed above in “— Payments of Interest”) unless:

•

the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable); or

•

the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met.

Gain realized by a Non-U.S. Holder described in the first bullet point above generally will be subject to U.S. federal income tax in the same manner as effectively connected interest income as described above (and, if the Non-U.S. Holder is a corporation, possibly branch profits tax as described above).

Gain realized by a Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) and may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

Non-U.S. Holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of interest generally will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder certifies its non-U.S. status as described above under “— Payments of Interest.” However, information returns are required to be filed with the IRS in connection with any interest paid to Non-U.S. Holders, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of a note (including a retirement or redemption of the note) within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the statement described above and does not have actual knowledge or reason to know that such holder is a United States person or the holder otherwise

S-24

establishes an exemption. Proceeds of a disposition of a note paid outside the United States and conducted through a non-U.S. office of a non-U.S. broker (other than a U.S.-related broker mentioned above) generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on payments of interest on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, a note paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of interest on a note. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of a note, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

PROSPECTIVE INVESTORS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE POTENTIAL APPLICATION OF WITHHOLDING UNDER FATCA TO THEIR INVESTMENT IN THE NOTES.

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase and holding of the notes by (i) “employee benefit plans” within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) that are subject to Title I of ERISA, (ii) plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under any other U.S. or non-U.S. federal, state, local or other laws or regulations that are similar to such provisions of the Code or ERISA (collectively, “Similar Laws”), and (iii) entities whose underlying assets are considered to include plan assets of any of the foregoing described in clauses (i) or (ii) pursuant to ERISA or other applicable law (each of the foregoing described in clauses (i), (ii) and (iii) referred to herein as a “Plan”).

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (each, a “Covered Plan”) and prohibit certain transactions involving the assets of a Covered Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of a Covered Plan or over the management or disposition of a Covered Plan’s assets, or who renders investment advice for a fee or other compensation with respect to such assets, is generally considered to be a fiduciary of the Covered Plan.

Any Plan fiduciary that proposes to cause a Plan to purchase or hold the notes should consult with its legal advisors regarding the potential applicability of the fiduciary responsibility and prohibited transaction provisions of Title I of ERISA, Section 4975 of the Code or applicable Similar Laws to such an investment, and to confirm that such purchase and holding will not constitute or result in a non-exempt prohibited transaction or any other violation of an applicable requirement of ERISA, Section 4975 of the Code or applicable Similar Law. In considering an investment in the notes with a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or Similar Laws relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit Covered Plans from engaging in specified transactions involving Covered Plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. Those sections further prohibit a fiduciary from engaging in transactions in which a conflict of interest is deemed present. A party in interest or disqualified person (including a fiduciary) who engaged in a non-exempt prohibited transaction with the Covered Plan may be subject to excise taxes and other penalties and liabilities under ERISA and/or the Code. In addition, the fiduciary of a Covered Plan that caused the Covered Plan to engage in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA. The acquisition and/or holding of the notes by a Covered Plan with respect to which we, an underwriter or any of our or their respective affiliates may be considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption. An additional consideration would be whether the Covered Plan fiduciary is, or has an interest that may affect the exercise of its best judgment as a fiduciary in, a lender in any of the borrowings that are expected to be repaid, in whole or in part, with the proceeds of this offering, as described in “Use of Proceeds” in this prospectus supplement.

In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or “PTCEs,” that may provide exemptive relief for direct or indirect prohibited transactions resulting from the sale, purchase or holding of the notes. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment

S-26

Table of Contents

funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers, although there can be no assurance that all of the conditions of any such exemptions will be satisfied. In addition to the foregoing, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide exemptions for certain transactions between a Covered Plan and a person that is a party in interest and/or a disqualified person (other than a fiduciary or an affiliate that, directly or indirectly, has or exercises any discretionary authority or control or renders any investment advice with respect to the Covered Plan assets involved in the transaction) solely by reason of providing services to the Covered Plan or by relationship to a service provider, provided that the Covered Plan has paid no more and received no less than adequate consideration in connection with the transaction. These exemptions do not, however, provide relief from the self-dealing prohibited transactions under ERISA and the Code. It should also be noted that even if the conditions specified in one or more of these exemptions are met, the scope of relief provided by these exemptions may not necessarily cover all acts involving the notes that might be construed as prohibited transactions.

Other Plans

Plans, including governmental plans (as defined in Section 3(32) of ERISA) and, if no election has been made under Section 410(d) of the Code, church plans (as defined in Section 3(33) of ERISA), and non-U.S. Plans (as described in Section 4(b)(4) of ERISA), while generally not subject the fiduciary responsibility provisions of Title I of ERISA or to the prohibited transaction provisions of Title I of ERISA or Section 4975 of the Code, may be subject to Similar Laws that include similar requirements. Fiduciaries of any such Plans should consult with their legal advisors regarding the potential consequences of an investment in the notes under any applicable Similar Laws before purchasing any notes.

Because of the foregoing, the notes should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding will not constitute or result in a non-exempt prohibited transaction under ERISA and/or the Code or a similar violation under any applicable Similar Laws.

Representation

Accordingly, by acceptance of and/or holding a note or any interest in a note, each purchaser and subsequent transferee of a note will be deemed to have represented and warranted that either (a) such purchaser or subsequent transferee is not acquiring or holding the notes for or on behalf of, and no portion of the assets used by such purchaser or transferee to acquire or hold the notes or any interest therein constitutes assets of, any Plan or (b) the acquisition, holding and subsequent disposition of the notes by such purchaser or transferee will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all-inclusive nor should it be construed as legal advice. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing or holding the notes (including any beneficial interest therein) on behalf of, or with the assets of, any Plan, consult with their advisors regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and/or holding of the notes.

Nothing herein shall be construed as a representation or recommendation that such an investment meets all relevant legal requirements with respect to investments by Plans generally or any particular Plan or that such an investment is appropriate or advisable for Plans generally or any particular Plan.

Each purchaser and holder of the notes has the exclusive responsibility for ensuring that its purchase and holding of the notes complies with the fiduciary responsibility rules of Title I of ERISA and does not violate the prohibited transaction rules of ERISA or Section 4975 of the Code or any Similar Laws, as applicable. Neither this discussion nor anything provided in this prospectus supplement is or is intended to be investment advice directed at any potential Plan purchasers or at Plan purchasers generally and such purchasers of any notes (or beneficial interests therein) should consult and rely on their own advisors as to whether an investment in the notes is suitable for the Plan.

UNDERWRITING (CONFLICTS OF INTEREST)

We and the underwriters named below have entered into an underwriting agreement with respect to the notes. BofA Securities, Inc, J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, PNC Capital Markets LLC and Truist Securities, Inc. are acting as representatives of the several underwriters. Subject to the terms and conditions in the underwriting agreement, we have agreed to sell to each underwriter, and each underwriter has severally and not jointly agreed to purchase from us, the principal amount of notes that appears opposite its name in the table below:

Underwriters	Aggregate Principal Amount of Notes to be Purchased
BofA Securities, Inc.		$
J.P. Morgan Securities LLC		$
Wells Fargo Securities, LLC		$
PNC Capital Markets LLC		$
Truist Securities, Inc.		$
Total		$

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters have agreed to purchase all of the notes if any of them are purchased.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected securities dealers at the public offering price minus a concession of up to % of the principal amount of the notes. In addition, the underwriters may allow, and those selected dealers may re-allow, a concession of up to % of the principal amount per note to certain other brokers or dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

In the underwriting agreement, we have agreed that:

•

We will pay our expenses related to the offering, which we estimate will be $ million, excluding the underwriting discount.

•

We will indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

The following table shows the underwriting discount that we will pay to the underwriters in connection with this offering of the notes (expressed as a percentage of the principal amount of the notes):

	Underwriting Discount Paid by the Company
	Per note			Total
	%			$

The notes are a new issue of securities with no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so. The underwriters may discontinue any market making in the notes at any time without notice in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

S-28

Table of Contents

In connection with this offering of the notes, the underwriters may engage in overallotments, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes, as applicable. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

Certain of the underwriters and their affiliates have, from time to time, performed, and may in the future perform, various financial advisory, commercial banking and investment banking services for us and our affiliates for which they received, or will receive, customary fees and expenses. Certain of the underwriters (or affiliates thereof) are acting as joint lead arrangers, joint bookrunners, syndication agents, administrative agents, adjustment agents, dealers, co-managers or lenders under our credit facilities, including our Financing Agreements. In addition, certain affiliates of BofA Securities, Inc., J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, PNC Capital Markets LLC and Truist Securities, Inc. are providing committed financing under the Financing Agreements and/or own our commercial paper, and BofA Securities, Inc., J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, PNC Capital Markets LLC and Truist Securities, Inc. are underwriters in this offering. As described under “Use of Proceeds,” we intend to use the net proceeds of this offering and the Concurrent Securities Offerings to repay all or a portion of the outstanding borrowings under the Financing Agreements and/or our commercial paper borrowings. As such, certain of the underwriters and their affiliates, who are lenders under our Financing Agreements or may own our commercial paper, may receive at least 5% of the net proceeds of this offering, after deducting underwriting discounts and estimated offering expenses payable by us. Because 5% or more of the net proceeds of this offering may be paid to any underwriter and its affiliates, which is considered a “conflict of interest” under FINRA Rule 5121, this offering will be made in accordance with the applicable requirements of FINRA Rule 5121 regarding the underwriting of securities of a company with a member that has a conflict of interest within the meaning of those rules. Pursuant to FINRA Rule 5121(a)(1)(C), the appointment of a qualified independent underwriter is not necessary in connection with this offering because the notes offered pursuant to this prospectus supplement are investment grade rated under the requirements of paragraph (f)(8) of FINRA Rule 5121. In accordance with FINRA Rule 5121(c), no sales of the notes will be made to any discretionary account over which any underwriter with a conflict of interest exercises discretion without the prior specific approval of the account holder.

To the extent any underwriter that is not a U.S.-registered broker-dealer intends to effect sales of the notes in the United States, it will do so through one or more U.S.-registered broker-dealers in accordance with the applicable U.S. securities laws and regulations.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and instruments of ours or our affiliates. Certain of the underwriters and their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or financial instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) using a shelf registration process. Under this shelf process, we may, from time to time, sell the securities described in this prospectus in one or more offerings.

This prospectus contains a general description of the securities that we may offer. Each time we sell any securities pursuant to this prospectus, we will provide a prospectus supplement that will contain specific information about the terms of that offering. Material federal income tax considerations applicable to the offered securities will also be discussed in the applicable prospectus supplement as necessary. The prospectus supplement also may add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. You should read this prospectus and the applicable prospectus supplement, together with the additional information described below under the heading “Where You Can Find More Information,” before you decide whether to invest in the securities.

You should rely only on the information contained in or incorporated by reference into this prospectus and any prospectus supplement or other offering materials we provide. We have not authorized anyone to provide you with additional or different information. If anyone does provide you with additional or different information, you should not rely on it. You should not assume that the information contained in this prospectus or any prospectus supplement is accurate as of any date other than the date on the front cover of this prospectus or any such prospectus supplement. You also should not assume that the information contained in any document incorporated by reference into this prospectus or any prospectus supplement is accurate as of any date other than the date of the document incorporated by reference, regardless of the time of delivery of this prospectus or any such prospectus supplement. Our business, financial condition, results of operations and/or prospects may have changed since the date of this prospectus, any prospectus supplement or any document incorporated by reference into this prospectus or any prospectus supplement.

FORWARD-LOOKING STATEMENTS

This prospectus contains or incorporates by reference “forward-looking” statements, as defined in the Private Securities Litigation Reform Act of 1995, that are based on our current expectations, estimates and projections about future events and financial trends affecting the financial condition and operations of our business. Forward-looking statements include all statements that are not historical facts. In some cases, forward-looking statements can be identified by the use of words such as “may,” “will,” “should,” “could,” “believe,” “anticipate,” “expect,” “estimate,” “plan” or other comparable terminology. Forward-looking statements are inherently subject to risks and uncertainties, many of which we cannot predict with accuracy and some of which we might not even anticipate. Although we believe that the expectations, estimates and projections reflected in such forward-looking statements are based on reasonable assumptions at the time made, we can give no assurance that these expectations, estimates and projections will be achieved. Future events and actual results may differ materially from those discussed in the forward-looking statements. We caution readers that forward-looking statements reflect our opinion only as of the date on which they were made. You should not place undue reliance on forward-looking statements. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

•

our ability to consummate and successfully integrate future acquisitions;

•

risks associated with international sales and operations, including supply chain disruptions;

•

tariffs, trade disputes, foreign currency fluctuations and geopolitical developments;

•

our ability to successfully develop new products, open new facilities or transfer product lines;

•

the price and availability of raw materials;

•

cybersecurity and information technology risks;

•

compliance with government regulations, including environmental regulations;

•

changes in the competitive environment;

•

the effects of competition in our markets;

•

the ability to maintain adequate liquidity and financing sources; and

•

general economic conditions affecting the industries we serve.

These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included or incorporated by reference in this prospectus and any applicable prospectus supplement. Numerous factors, including those discussed in the documents referred to under the heading “Risk Factors” which include our filings with the SEC referred to under the heading “Where You Can Find More Information” could affect our forward-looking statements and actual performance. Although we undertake no obligation to publicly update or supplement forward-looking statements whether as a result of new information, future events or otherwise, you are advised to consult any additional disclosures we make in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K filed with the SEC.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described under the heading “Risk Factors” contained in the applicable prospectus supplement and any related free writing prospectus, and under similar headings in our Annual Report on Form 10-K for the year ended December 31, 2025, as updated by our subsequent filings, which are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. Each of the risk factors could adversely affect our business, results of operations, financial condition and cash flows, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations.

USE OF PROCEEDS

Table of Contents

DESCRIPTION OF CAPITAL STOCK

General

The following summary description of our capital stock is intended as a summary only and therefore is not a complete description of our capital stock. This description is based on, and qualified by reference to, the applicable provisions of Delaware corporate law (the “DGCL”), our amended and restated certificate of incorporation (the “Amended and Restated Certificate of Incorporation”) and our by-laws (the “Bylaws”), each as amended and restated, as applicable, through the date of this prospectus and both of which are exhibits to this prospectus. You should read our Amended and Restated Certificate of Incorporation and Bylaws and applicable provisions of the DGCL for additional information. References to “AMETEK,” “we,” “our,” and “us” in this “Description of Capital Stock” refer only to AMETEK, Inc. and not, unless the context requires or as otherwise expressly stated, to any of our subsidiaries.

Common Stock

Authorized Shares

Under our Amended and Restated Certificate of Incorporation, we have the authority to issue 800,000,000 shares of common stock, with a par value of $0.01 per share.

Voting Rights

Holders of our common stock are entitled to one vote per share on all matters voted on by our stockholders.

Dividend Rights

The holders of our common stock are entitled to receive dividends when, as, and if declared by our board of directors out of legally available funds, subject to the rights of any then outstanding preferred stock.

Liquidation Rights

Upon a liquidation or dissolution of the Company, whether voluntary or involuntary, all shares of our common stock are entitled to share equally and ratably in the assets available for distribution to holders of common stock after payment of all of our prior obligations, subject to the rights of any then outstanding preferred stock.

Other Matters

The holders of our common stock have no preemptive, conversion or exchange rights. There are no redemption or sinking fund provisions applicable to our common stock.

Certain Anti-Takeover Effects

Certain provisions of the DGCL and our Amended and Restated Certificate of Incorporation and Bylaws contain provisions that could have certain anti-takeover effects and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests, as discussed below:

Authorized but Unissued Shares. Subject to the requirements of the New York Stock Exchange and other applicable law, our authorized but unissued shares of common stock may be available for future issuance without stockholder approval. We may use these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans.

Undesignated Preferred Stock. Our Amended and Restated Certificate of Incorporation provides that our board of directors may issue up to 5,000,000 shares of preferred stock and fix the designations, relative powers, preferences, rights, qualifications, limitations and restrictions related to that preferred stock.

Table of Contents

Advance Notice Requirements. Our Bylaws establish an advance notice procedure for stockholders seeking to nominate candidates for election to the board of directors or for proposing matters which can be acted upon at stockholders’ meetings.

Special Meetings of Stockholders. Our Amended and Restated Certificate of Incorporation and Bylaws vest the power to call special meetings of our stockholders in the chairman of our board of directors, our board of directors and stockholders of record, who hold a “net long position” (as defined in our Bylaws), of not less than 50% of our then outstanding voting stock (subject to the procedures and other requirements set forth in our Bylaws).

No Action by Written Consent. Our Amended and Restated Certificate of Incorporation provides that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of the stockholders and may not be effected by any consent in writing of such stockholders.

Classified Board of Directors. Our board of directors is divided into three classes with staggered terms of three years each, so that the term of one class expires at each annual meeting of the stockholders.

Proxy Access. Our Bylaws contain provisions which provide that a stockholder, or group of up to 20 stockholders, that has owned continuously for at least three years capital stock of the Company representing an aggregate of at least 3% of the Company’s voting stock, may nominate and include in the Company’s proxy materials a specified number of director nominees, provided that the stockholder(s) and nominee(s) satisfy the requirements in our Bylaws. The maximum number of stockholder nominees is the greater of (x) two or (y) a number that does not exceed 20% of the total number of our directors in office as of the last day on which notice of a nomination may be delivered or, if such amount is not a whole number, the closest whole number below 20%.

No Cumulative Voting. Our Amended and Restated Certificate of Incorporation and Bylaws do not provide for cumulative voting on the election of directors.

Delaware Business Combination Statute. As a Delaware corporation, we are subject to Section 203 of the DGCL. In general, Section 203 of the DGCL provides that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that such stockholder becomes an interested stockholder unless:

•

prior to such time, our board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

•

upon consummation of the transaction which resulted in the stockholder becoming an “interested stockholder,” the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced (excluding certain shares); or

•

on or subsequent to such time, the business combination is approved by our board of directors and authorized at a meeting of stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our voting stock.

Exclusive Forum for Adjudication of Disputes

Our Bylaws provide that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if such court lacks jurisdiction, another state court located within the State of Delaware, or if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for (a) any derivative action or other proceeding brought on behalf of the Company, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or to the Company’s stockholders, creditors or other constituents, (c) any action asserting a claim against the

Table of Contents

Company or any director or officer of the Company arising pursuant to any provision of the DGCL or our Amended and Restated Certificate of Incorporation or Bylaws, or (d) any action asserting a claim against the Company or any director or officer of the Company governed by the internal affairs doctrine. Our Bylaws provide that any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Company shall be deemed to have notice of and consented to the exclusive forum provision.

Transfer Agent

Equiniti Trust Company, LLC serves as transfer agent and registrar for our common stock.

Preferred Stock

Under our Amended and Restated Certificate of Incorporation, we have the authority to issue 5,000,000 shares of preferred stock. The Board is authorized to issue preferred stock in one or more series, with the designations, relative powers, preferences, rights, qualifications, limitations, restrictions, voting powers, redemption provisions, dividend rights and any other relative, participating, optional, or other special powers, preferences, rights, qualifications, limitations or restrictions thereof, in each case, as permitted by the DGCL and as our Board may determine by a resolution providing for the issuance of such preferred stock. The preferred stock will be, when issued, fully paid and nonassessable. The rights, preferences, privileges and restrictions of any series of preferred stock will be fixed by the Preferred Stock Designation relating to such series of shares.

Depositary Shares

We may, at our option, elect to offer depositary shares representing fractional shares of our preferred stock, rather than full shares of preferred stock. The shares of preferred stock represented by depositary shares will be deposited under a depositary agreement between us and a bank or trust company that meets certain requirements and is selected by us (the “Bank Depositary”). Each owner of a depositary share will be entitled to all the rights and preferences of the preferred stock represented by the depositary share.

The description in an accompanying prospectus supplement of any depositary shares we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable depositary agreement, which will be filed with the SEC if we offer depositary shares. For more information on how you can obtain copies of any depositary agreement if we offer depositary shares, see “Where You Can Find More Information.” We urge you to read the applicable depositary agreement and any accompanying prospectus supplement in their entirety.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of shares of our common stock, shares of our preferred stock or our debt securities. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants is expected to be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as shall be detailed in an accompanying prospectus supplement relating to the particular series of warrants. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you. The following summaries of certain provisions of the warrants are not complete and are subject to, and are qualified in their entirety by reference to, all the provisions of any related warrant agreement and warrant certificate, respectively, which will be filed with the SEC as an exhibit to, or incorporated by reference in, the registration statement of which this prospectus is a part.

the date on which the right to exercise the warrants will commence and the date on which the warrants will expire;

•

the name of the warrant agent; and

any other material terms of the warrant.

After the warrants expire, they will become void. The prospectus supplement may provide for the adjustment of the exercise price of the warrants.

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in an accompanying prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise of such warrant and will not be entitled to payments made to holders of those underlying securities.

DESCRIPTION OF DEBT SECURITIES

References to “AMETEK” in this section of this prospectus are only to AMETEK, Inc. and not to any of its subsidiaries.

We may issue debt securities, including convertible debt securities, in one or more series. While the terms summarized below will apply generally to any future debt securities we may offer under this prospectus, the applicable prospectus supplement or free writing prospectus will describe the specific terms of any debt securities offered through that prospectus supplement or free writing prospectus. The terms of any debt securities AMETEK offers under a prospectus supplement or free writing prospectus may differ from terms we describe below.

We will evidence each series of debt securities offered under this prospectus that we issue by the indenture (the “base indenture”), dated as of November 10, 2026, between AMETEK and U.S. Bank Trust Company, National Association (the “trustee”). The base indenture is included as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures, officer’s certificates and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that AMETEK files with the SEC. Unless the context requires otherwise, whenever AMETEK refers to the “indenture,” AMETEK is referring to the base indenture as supplemented by any supplemental indentures or officer’s certificates that specify the terms of a particular series of debt securities.

The indenture is qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act.

The following summaries of material provisions of the debt securities and the indenture are subject to, and qualified in their entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplement and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete applicable indenture that contains the terms of the debt securities.

General

We will set forth in a prospectus supplement or free writing prospectus, to the extent required, among other things, the following terms of the series of debt securities being offered:

•

the title of the series of the debt securities;

•

any limit on the aggregate principal amount of the debt securities of a series;

•

the date or dates on which AMETEK will pay the principal of the debt securities;

•

any sinking fund or other provision for payment of the debt securities prior to their stated maturity;

•

the rate or rates at which the debt securities will bear interest or, if applicable, the method used to determine such rate or rates;

•

the date or dates from which interest will accrue, the date or dates on which interest will be payable and any record date for the interest payable on any interest payment date;

•

the place or places where principal of and any premium and interest on the debt securities of the series will be payable;

•

any optional redemption provisions and any change of control or put provisions;

•

if other than the principal amount thereof, the amounts payable upon a declaration of acceleration of the maturity of the debt securities;

•

the issue date;

•

the issue price (expressed as a percentage of the aggregate principal amount of the debt securities) at which the debt securities will be issued;

Table of Contents

•

whether the debt securities will be issued in the form of definitive debt securities or global debt securities and, if issued in the form of global debt securities, the identity of the depositary for such global debt security or debt securities;

•

any additions to, deletions of or changes in the events of default which apply to the debt securities;

•

if the debt securities will be convertible into or exchangeable for shares of common stock, preferred stock or other securities of AMETEK;

•

any additions to, deletions of or changes in the covenants which apply to the debt securities; and

•

any other terms of the debt securities (which may supplement, modify or delete any provision of the indenture insofar as it applies to such series).

The debt securities will be issuable only in fully registered form, without coupons, or in the form of one or more global debt securities. The debt securities will be issued only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, unless otherwise specified in the applicable prospectus supplement or free writing prospectus.

The indenture does not limit the aggregate principal amount of debt securities that may be issued under it. Unless otherwise provided in the terms of a series of debt securities, a series may be reopened, without notice to or consent of any holder of outstanding debt securities, for issuances of additional debt securities of that series.

Unless otherwise indicated in the applicable prospectus supplement or free writing prospectus, principal of and interest and premium, if any, on the debt securities will be payable at our office or agency maintained for this purpose within New York City, or, at our option, payment of interest on the debt securities may be made by check mailed to the holders of the debt securities at their respective addresses set forth in the register of holders of debt securities. Unless otherwise indicated in the prospectus supplement or free writing prospectus, the trustee will initially be a paying agent and registrar under the indenture. We may act as paying agent or registrar under the indenture.

Unless otherwise indicated in the applicable prospectus supplement or free writing prospectus, interest will be computed on the basis of a 360-day year of twelve 30-day months. If a payment date is not a business day, payment may be made on the next succeeding day that is a business day, and interest will not accrue for the intervening period.

Certain Covenants

The indenture governing the terms of the debt securities contains the following principal covenant:

Limitation on Consolidation, Merger and Sale of Assets

AMETEK may not consolidate or merge with or into another entity, or sell, lease, convey, transfer or otherwise dispose of its assets substantially as an entirety to another entity unless:

•

(1) AMETEK is the continuing corporation or (2) the successor entity, if other than AMETEK, is a U.S. corporation, partnership, limited liability company or trust and expressly assumes by supplemental indenture all of AMETEK’s obligations under the debt securities of all series and the indenture;

•

immediately after giving effect to the transaction, no event of default (as defined below), and no default or other event that, after notice or lapse of time or both, would become a default or event of default, has occurred and is continuing; and

•

certain other conditions are met, including delivery by us to the trustee of an officer’s certificate and opinion of counsel as required by the indenture.

In the case of any such consolidation, merger, sale, transfer or other conveyance, but not a lease, in a transaction in which there is a successor entity, the successor entity will succeed to, and be substituted for,

Table of Contents

and may exercise every right and power of AMETEK under the indenture and, subject to the terms of the indenture, AMETEK will be discharged from all obligations and covenants under the indenture and the debt securities.

Further Issuances

AMETEK may from time to time, without notice to or the consent of the holders of the debt securities of any series, create and issue additional debt securities having the same terms as, and ranking equally and ratably with, the debt securities of such series in all respects (except for the issue date, the issue price and, if applicable, the first interest payment date, the first interest accrual date and the amount of interest payable on the first interest payment date applicable thereto). Such additional debt securities may be consolidated and form a single series with, and will have the same terms as to ranking, redemption, waivers, amendments or otherwise, as a previously issued series of debt securities and will vote together as one class on all matters with respect to such debt securities.

Events of Default

Each of the following is an “event of default” under the indenture with respect to the debt securities of any series:

(1)

a failure to pay principal of or premium, if any, on the debt securities of such series when due at its stated maturity date, upon optional redemption or otherwise;

(2)

a default in the payment of any interest on the debt securities of such series when due and payable, continued for 60 days;

(3)

a default in the performance, or breach, of any other covenant, warranty or agreement in the indenture (other than a default or breach pursuant to clause (4) immediately below), and continuance of such default or breach for 90 days after a Notice of Default (as defined below) is given to AMETEK;

(4)

a default in the performance, or breach, of AMETEK’s obligations under the “— Certain Covenants — Limitation on Consolidation, Merger and Sale of Assets” covenant described above;

(5)

an involuntary proceeding shall be commenced or an involuntary petition shall be filed seeking (i) liquidation, reorganization or other relief in respect of AMETEK or its debts, or of a substantial part of its assets, under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect or (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for AMETEK or for a substantial part of its assets, and, in any such case, such proceeding or petition shall continue undismissed for 90 days or an order or decree approving or ordering any of the foregoing shall be entered; and

(6)

AMETEK shall (i) voluntarily commence any proceeding or file any petition seeking liquidation, reorganization or other relief under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any proceeding or petition described in clause (5) above, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for AMETEK or for a substantial part of its assets, (iv) make a general assignment for the benefit of creditors or (v) take any action for the purpose of effecting any of the foregoing.

A default under clause (3) above is not an event of default until the trustee or the holders of not less than 25% in aggregate principal amount of the debt securities of such series then outstanding notify AMETEK of the default and AMETEK does not cure such default within the time specified after receipt of such notice. Such notice must specify the default, demand that it be remedied and state that such notice is a “Notice of Default.”

AMETEK shall deliver to the trustee, within 30 days after the occurrence thereof, written notice in the form of an officer’s certificate of any event that with the giving of notice or the lapse of time or both would become an event of default, its status and what action AMETEK is taking or proposes to take with

Table of Contents

respect thereto. Upon becoming aware of any default or event of default, AMETEK is required to deliver to the trustee a statement specifying such default or event of default.

If an event of default (other than an event of default resulting from certain events involving bankruptcy, insolvency or reorganization) with respect to debt securities of any series shall have occurred and be continuing, the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such series may declare, by notice to AMETEK in writing (and to the trustee, if given by the holders of the debt securities) specifying the event of default, to be immediately due and payable the principal amount of all the outstanding debt securities of such series, plus accrued but unpaid interest to the date of acceleration. In case an event of default resulting from certain events of bankruptcy, insolvency or reorganization with respect to AMETEK shall occur, such amount with respect to all the outstanding debt securities of such series shall be due and payable immediately to the fullest extent permitted by applicable law without any declaration or other act on the part of the trustee or the holders of the outstanding debt securities of such series. Unless as otherwise provided in the indenture, after any such acceleration, but before a judgment or decree based on acceleration is obtained by the trustee, the holders of a majority in aggregate principal amount of outstanding debt securities of such series may, under certain circumstances, rescind and annul such acceleration and waive such event of default with respect to the outstanding debt securities of such series if (i) AMETEK has paid or deposited with the trustee a sum sufficient to pay all overdue principal, premium, interest and all amounts due to the trustee and (ii) all events of default, other than the nonpayment of accelerated principal, premium or interest with respect to the outstanding debt securities of such series, have been cured or waived as provided in the indenture.

In case an event of default shall occur and be continuing with respect to a series of debt securities, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders of the debt securities of such series, unless such holders shall have offered (and, if requested, provided) to the trustee indemnity and/or security satisfactory to the trustee against any loss, liability or expense. Subject to such provisions for the indemnification and/or security of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities of such series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of such series.

No holder of debt securities of any series will have any right to institute any proceeding with respect to the indenture unless:

(a)

such holder has previously given to the trustee written notice of a continuing event of default with respect to the debt securities of such series;

(b)

the holders of at least 25% in aggregate principal amount of the debt securities of such series then outstanding have made written request and offered the trustee indemnity and/or security satisfactory to the trustee to institute such proceeding as trustee;

(c)

the trustee has failed to institute such proceeding within 60 days after its receipt of such notice, request and offer of indemnity and/or security; and

(d)

the trustee shall not have received from the holders of a majority in aggregate principal amount of the debt securities of such series then outstanding a direction inconsistent with such request during the 60 day period referred to in clause (c).

However, such limitations do not apply to a suit instituted by a holder of any debt securities for enforcement of payment of the principal of, and premium, if any, or interest on, such debt securities on or after the respective due dates expressed in such debt securities.

The indenture requires AMETEK to furnish to the trustee, within 120 days after the end of each fiscal year, a statement of an officer regarding compliance with the indenture.

The holders of at least a majority in aggregate principal amount of the outstanding debt securities may waive any past default under the indenture, except a default not theretofore cured in the payment of principal or interest and certain covenants and provisions of the indenture which cannot be amended without the consent of the holder of each outstanding debt security.

Defeasance

AMETEK at any time may terminate all its obligations with respect to the debt securities of any series (such termination, “legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the debt securities of such series, to replace mutilated, destroyed, lost or stolen debt securities and to maintain a registrar and paying agent in respect of the debt securities of such series. AMETEK at any time may also terminate its obligations with respect to the debt securities of any series under certain covenants included in the indenture, including those described under clause (3) under “— Events of Default,” which termination is referred to in this prospectus as “covenant defeasance.” AMETEK may exercise its legal defeasance option with respect to any series of debt securities notwithstanding its prior exercise of its covenant defeasance option with respect to such series of debt securities.

Table of Contents

If AMETEK exercises its legal defeasance option with respect to the debt securities of any series, payment of the debt securities of such series may not be accelerated because of an event of default with respect thereto. If AMETEK exercises its covenant defeasance option with respect to the debt securities of any series, payment of the debt securities of such series may not be accelerated because of an event of default specified in clauses (3) and (6) under “— Events of Default” and with respect to certain covenants in the indenture, including those described under “— Certain Covenants.”

The legal defeasance option or the covenant defeasance option with respect to the debt securities of any series may be exercised only if:

(a)

AMETEK irrevocably deposits in trust with the trustee money or U.S. government securities or a combination thereof, which through the payment of interest thereon and principal thereof in accordance with their terms, will provide money in an amount sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay principal and interest when due on all the debt securities being defeased to maturity;

(b)

no default or event of default with respect to the debt securities of such series has occurred and is continuing on the date of such deposit, or, with respect to an event of default involving bankruptcy, at any time in the period ending on the 91st day after the date of deposit;

(c)

in the case of the legal defeasance option, AMETEK delivers to the trustee an opinion of counsel stating that:

(1)

AMETEK has received from the Internal Revenue Service a ruling, or

(2)

since the date of the indenture there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders of the debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same time as would have been the case if such legal defeasance has not occurred;

(d)

in the case of the covenant defeasance option, AMETEK delivers to the trustee an opinion of counsel to the effect that the holders of the debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and

(e)

AMETEK delivers to the trustee an officer’s certificate and an opinion of counsel, each stating that all conditions precedent to the defeasance and discharge of the debt securities of such series have been complied with as required by the indenture.

Discharge

When (i) AMETEK delivers to the trustee all outstanding debt securities of any series (other than debt securities replaced or paid because of mutilation, loss, destruction or wrongful taking) for cancellation or (ii) all outstanding debt securities of any series have become due and payable, or are by their terms due and payable within one year whether at maturity or are to be called for redemption within one year under arrangements reasonably satisfactory to the trustee, and in the case of clause (ii) AMETEK irrevocably deposits with the trustee funds sufficient to pay at maturity or upon redemption all outstanding debt securities of such series, including interest thereon, and if in either case AMETEK pays all other sums related to the debt securities of such series payable under the indenture by AMETEK, then the indenture shall, subject to certain surviving provisions, cease to be of further effect with respect to such series. The trustee shall acknowledge satisfaction and discharge of the indenture with respect to the debt securities of such series on demand of AMETEK accompanied by an officer’s certificate and an opinion of counsel of AMETEK.

Governing Law

The indenture is, and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

PLAN OF DISTRIBUTION

We may sell the securities being offered under this prospectus in any one or more of the following ways:

•

directly to purchasers;

•

through agents;

•

to or through underwriters;

•

through dealers; or

•

through a combination of any of these methods of sale.

We may distribute the securities from time to time in one or more transactions at:

•

a fixed price or prices, which may be changed;

•

market prices prevailing at the time of sale;

•

prices related to prevailing market prices;

•

negotiated prices; or

•

through a combination of any of these transactions.

We may directly solicit offers to purchase securities or we may designate agents to solicit such offers. We will, in the prospectus supplement or other offering materials relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act of 1933, as amended (the “Securities Act”), and describe any commissions we must pay. Any such agent will be acting on a “best efforts” basis for the period of its appointment or, if indicated in the applicable prospectus supplement or other offering materials, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement or other offering materials relating to such offering their names and the terms of our agreement with them.

If a dealer is utilized in the sale of the securities in respect of which this prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Agents, underwriters and dealers may be entitled under relevant agreements with us to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such agents, underwriters and dealers may be required to make in respect thereof. The terms and conditions of any indemnification or contribution will be described in the applicable prospectus supplement.

Agents, underwriters and dealers may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may over-allot in connection with the offering, creating a short position for their own accounts. In addition, to cover over-allotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.
