**SUMMARY** 

*The following information summarizes, and should be read in conjunction with, the information contained in this prospectus supplement and in the accompanying prospectus, and the documents incorporated herein and therein by reference. This summary is not complete and does not contain all of the information that you should consider before investing in the notes. Unless otherwise specified, any reference to a "year" is to a fiscal year ended June 30.* 

**Company Overview** 

With more than 85 years of materials expertise, Kennametal Inc. is a global industrial technology leader, that helps customers across the General Engineering, Transportation, Earthworks, Energy and Aerospace & Defense end markets build their products with precision and efficiency. Kennametal Inc. was founded based on a tungsten carbide technology breakthrough in 1938 and was incorporated in Pennsylvania in 1943 as a manufacturer of tungsten carbide metal cutting tooling. In 1967, it was listed on the New York Stock Exchange ("NYSE").

The Company's core expertise includes the development and application of tungsten carbides, ceramics, super-hard materials and solutions used in metal cutting and extreme wear applications to keep customers up and running longer against conditions such as corrosion and high temperatures. We bring together material science, technical expertise, innovation and customer service in a way that allows us to anticipate customers' needs and help them overcome problems and achieve their manufacturing objectives.

Our standard and custom product offering spans metal cutting and wear applications including turning, milling, hole making, tooling systems and services, as well as specialized wear components and metallurgical powders. End users of the Company's metal cutting products include manufacturers engaged in a diverse array of industries including: transportation vehicles and components, machine tools and light and heavy machinery; airframe and aerospace components; and energy-related components for the oil and gas industry, as well as power generation. The Company's wear and metallurgical powders are used by producers and suppliers in equipment-intensive operations such as road construction, mining, quarrying, oil and gas exploration, refining, production and supply, and for aerospace and defense.

Kennametal operates in two segments: Metal Cutting and Infrastructure. The Company's reportable operating segments have been determined in accordance with the Company's internal management structure, which is organized based on operating activities, the manner in which we organize segments for making operating decisions and assessing performance and the availability of separate financial results. Sales and operating income by segment are presented in the Management's Discussion and Analysis of Financial Condition and Results of Operations set forth in Item 7 of the Annual Report. Additional segment data is provided in Note 21 of our consolidated financial statements set forth in Item 8 of the Annual Report.

**Metal Cutting Segment** 

The Metal Cutting segment develops and manufactures high performance tooling and metal cutting products and services and offers an assortment of standard and custom metal cutting solutions to diverse end markets, including General Engineering, Transportation, Aerospace & Defense and Energy. The products include milling, hole making, turning, threading and toolmaking systems used in the manufacture of airframes, aero engines, trucks and automobiles, ships and various types of industrial equipment. We leverage advanced manufacturing capabilities in combination with varying levels of customization to solve our customers' toughest challenges and deliver improved productivity for a wide range of applications. Metal Cutting markets its products under the Kennametal<sup>®</sup>, WIDIA<sup>®</sup>, WIDIA Hanita<sup>®</sup> and WIDIA GTD<sup>®</sup> brands through its direct sales force, a network of

------

##### [**Table of Contents**](#toc)
independent and national distributors, integrated supplier channels and digitally. Application engineers and technicians are critical to the sales process and directly assist our customers with specified product design, selection, application and support.

**Infrastructure Segment** 

Our Infrastructure segment produces engineered tungsten carbide and ceramic components, earth-cutting tools, and advanced metallurgical powders, primarily for the Earthworks, General Engineering, Energy and Aerospace & Defense end markets. These wear-resistant products include compacts, nozzles, frac seats and custom components used in oil and gas and petrochemical industries; rod blanks and abrasive water jet nozzles for general industries; earth cutting tools and systems used in underground mining, trenching and foundation drilling and road milling; tungsten carbide powders for the oil and gas, aerospace and process industries; high temperature critical wear components, tungsten penetrators and armor solutions for aerospace and defense; and ceramics used by the packaging industry for metallization of films and papers. We combine deep metallurgical and engineering expertise with advanced manufacturing capabilities, such as 3D printing, to deliver solutions that drive improved productivity for our customers. Infrastructure markets its products primarily under the Kennametal<sup>®</sup> brand and sells through a direct sales force as well as through distributors.

**International Operations** 

During 2025, we generated 60 percent of our consolidated sales in markets outside of the United States of America ("U.S."), with principal international operations in Western Europe, China and India. We also operate manufacturing and distribution facilities in Israel, Latin America, South Africa and Vietnam, while serving customers through sales offices, agents and distributors in Europe and other parts of the world. While geographic diversification helps to minimize the sales and earnings effect of demand changes in any one particular region, our international operations are subject to normal risks of doing business globally, including tariffs, fluctuations in currency exchange rates and changes in social, political and economic environments.

**Principal Executive Office** 

Our principal executive offices are located at 525 William Penn Place Suite 3300, Pittsburgh, Pennsylvania 15219, and our telephone number is (412) 248-8000. Our website is www.kennametal.com. The information on our website is not part of this prospectus supplement or the accompanying prospectus.

**Recent Developments** 

**Tender Offer** 

Concurrent with this offering, we intend to commence a tender offer (the "Tender Offer") to purchase for cash any and all of our 4.625% Senior Notes due 2028 (the "2028 Tender Offer Notes"), of which $300 million aggregate principal amount is currently outstanding as of the date of this prospectus supplement, subject to certain terms and conditions of the Tender Offer, including the consummation of this offering.

| **Risk Factors**  | Investing in the notes involves significant risk. Before making a decision to invest in the notes, you should consider carefully all of the information set forth in this prospectus supplement and the accompanying prospectus and, in particular, you should evaluate the risk factors set forth under the heading "Risk Factors" beginning on page S-10 of this prospectus supplement and those set forth in our most recent Annual Report on Form 10-K and in our other periodic filings with the Securities and Exchange Commission, which are incorporated by reference in this prospectus supplement and the accompanying prospectus and may be obtained as described under "Where You Can Find More Information." |

**RISK FACTORS** 

*Investing in the notes involves significant risk. Before making a decision to invest in the notes, you should consider carefully the risk factors described below, and those set forth in our most recent Annual Report on Form 10-K and in other documents incorporated by reference in this prospectus supplement and the accompanying prospectus and which may be obtained as described under "Where You Can Find More Information," as well as the other information contained and incorporated by reference in this prospectus supplement, the accompanying prospectus and any related free writing prospectus. Each of these risks could have a material adverse effect on our business, results of operations and financial condition and the occurrence of any of these risks might cause you to lose all or part of your investment in the notes. These risks are not the only ones we face. Unforeseen risks could arise and problems or issues that we now view as minor could become more significant. If we are unable to adequately respond to these risks and uncertainties, our business, results of operations and financial condition would be materially adversely affected.* 

**Risks Related to the Offering and the Notes** 

**The Tender Offer may not be completed as contemplated or at all.** 

We will have broad discretion over the use of the net proceeds from this offering of the notes. As described in "Use of Proceeds" and "Summary—Recent Developments—Tender Offer" in this prospectus supplement, we currently anticipate using the net proceeds of the offering of the notes to fund the repurchase of the 2028 Tender Offer Notes pursuant to the Tender Offer. We anticipate using any remaining net proceeds for general corporate purposes.

However, we cannot predict the extent to which holders of the 2028 Tender Offer Notes will tender their 2028 Tender Offer Notes in the Tender Offer, and there can be no assurance that we will complete the Tender Offer as described herein, as contemplated in the Offer to Purchase, or at all, or that a significant amount of the 2028 Tender Offer Notes will be tendered or accepted for purchase by us. Therefore, we may use the net proceeds from this offering for purposes other than those contemplated herein. You may not agree with how we allocate or spend the net proceeds from this offering.

**The notes are effectively subordinated to the existing and future liabilities of our subsidiaries.** 

We have significant operations conducted through our subsidiaries. Accordingly, our cash flow and the consequent ability to service our debt, including the notes, are substantially dependent upon the earnings of our subsidiaries and the distribution of those earnings to us, whether by dividends, loans or otherwise. However, our subsidiaries are separate and distinct legal entities from us, and have no obligation to pay any amounts due on the notes or to provide us with funds to meet our payment obligations on the notes, whether in the form of dividends, distributions, loans or other payments. As a result, the notes will be effectively subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. As of March 31, 2026, our subsidiaries had approximately $1.4 million of indebtedness outstanding, and had no secured indebtedness. In addition, our significant domestic subsidiaries are guarantors and one of our foreign subsidiaries, Kennametal Europe GmbH, is a borrower under our existing credit agreement dated November 17, 2025, with the several banks and other financial institutions or entities from time to time parties thereto, Bank of America, N.A., London Branch, as euro swingline lender, PNC Bank, N.A., BNP Paribas and U.S. Bank National Association, as co-syndication agents, Citizens Bank, N.A., as documentation agent, and Bank of America, N.A., as administrative agent (the "Credit Agreement"). As of March 31, 2026, we had $15.3 million of borrowings outstanding and $634.7 million of additional borrowing capacity under our existing Credit Agreement.

Our right to receive any assets of any of our subsidiaries upon their bankruptcy, liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets, will also be effectively

------

##### [**Table of Contents**](#toc)
subordinated to the claims of that subsidiary's creditors, including trade creditors. In addition, even if we are a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us.

Our subsidiaries are not prohibited from incurring debt or other liabilities, including senior indebtedness, or from issuing equity interests that have priority over our interests in the subsidiaries. If our subsidiaries were to incur additional debt or liabilities or to issue equity interests that have priority over our interests in the subsidiaries, our ability to pay our obligations on the notes could be adversely affected. In addition, any payment of dividends, loans or advances by our subsidiaries could be subject to statutory or contractual restrictions. Payments to us by our subsidiaries will also be contingent upon the subsidiaries' earnings and business considerations.

**Our existing and future indebtedness may limit cash flow available to invest in the ongoing needs of our business, which could prevent us from fulfilling our obligations under the notes.** 

The indenture under which the notes will be issued will not limit the amount of indebtedness that we may incur. We also have the ability under our existing Credit Agreement to incur substantial additional indebtedness. As of March 31, 2026, we had $15.3 million of borrowings outstanding and $634.7 million of additional borrowing capacity under our existing Credit Agreement. We also borrow under short-term credit lines with commercial banks. These credit lines, translated into U.S. dollars at March 31, 2026 exchange rates, totaled $59.8 million. Our level of indebtedness could have important consequences to you. For example, it could:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• require us to dedicate a substantial portion of our cash flow from operations to the payment of debt service,
reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions or other general corporate purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase our vulnerability to adverse economic or industry conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our ability to obtain additional financing in the future to enable us to react to changes in our business;
or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• place us at a competitive disadvantage compared to businesses in our industry that have less indebtedness.

Additionally, any failure to meet required payments on our indebtedness, or failure to comply with any covenants in the instruments governing our indebtedness, could result in an event of default under the terms of those instruments. In the event of such default, the holders of such indebtedness could elect to declare all the amounts outstanding under such instruments to be due and payable. Any default under the agreements governing our indebtedness and the remedies sought by the holders of such indebtedness could render us unable to pay principal and interest on the notes and substantially decrease their value.

**Your right to receive payments on the notes is effectively subordinated to the rights of secured creditors.** 

The notes will be our general unsecured senior obligations. The notes will be effectively subordinated in right of payment to our secured indebtedness to the extent of the value of the collateral securing that indebtedness. The indenture under which the notes will be issued permits us to incur secured debt under specified circumstances. Any assets securing any of our secured indebtedness will be subject to prior claims by our secured creditors. In the event of our bankruptcy, insolvency, liquidation, reorganization, dissolution or other winding-up, any assets that secure any of our debt will be available to pay our obligations under the notes only after all debt secured by those assets, as well as any other obligations ranking senior in right of payment to the notes, have been repaid in full, and holders of the notes would then only be entitled to participate in our remaining assets, if any, ratably with all of our remaining unsecured senior creditors. If there are not sufficient assets remaining to pay all of these creditors, then all or a portion of the notes then outstanding and interest thereon would remain unpaid. As of March 31, 2026, we and our subsidiaries had no secured indebtedness.

------

##### [**Table of Contents**](#toc)
**The provisions of the notes will not necessarily protect you in the event of certain highly leveraged transactions.** 

Upon the occurrence of a Change of Control Triggering Event (as defined herein) you will have the right to require us to repurchase the notes as provided in the indenture governing the notes. However, the Change of Control Triggering Event provisions will not afford you protection in the event of certain highly leveraged transactions that may adversely affect you. For example, any leveraged recapitalization, refinancing, restructuring or acquisition initiated by us generally will not constitute a Change of Control (as defined herein) that would potentially lead to a Change of Control Triggering Event. As a result, we could enter into any such transaction even though the transaction could increase the total amount of our outstanding indebtedness, adversely affect our capital structure or credit rating or otherwise adversely affect the holders of the notes. These transactions may not involve a change in voting power or beneficial ownership or result in a downgrade in the ratings of the notes, or, even if they do, may not necessarily constitute a Change of Control Triggering Event that affords you the protections described in this prospectus supplement. If any such transaction were to occur, the value of your notes could decline.

Furthermore, the indenture for the notes does not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• require us to maintain any financial ratios or specific levels of net worth, revenues, income, cash flow or
liquidity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our ability to incur indebtedness that is equal in right of payment to the notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrict our subsidiaries' ability to issue securities or otherwise incur indebtedness that would be senior
to our equity interests in our subsidiaries and therefore rank effectively senior to the notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the ability of our subsidiaries to service indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrict our ability to repurchase or prepay any other of our securities or other indebtedness; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrict our ability to make investments or to repurchase or pay dividends or make other payments in respect of
our common stock or other securities ranking junior to the notes.

As a result of the foregoing, when evaluating the terms of the notes, you should be aware that the terms of the indenture and the notes do not restrict our ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events that could have an adverse impact on your investment in the notes. See "Description of the Notes—Change of Control Offer."

**We may not be able to repurchase all of the notes upon a Change of Control Triggering Event, which would result in an event of default under your notes.** 

We will be required to offer to repurchase the notes upon the occurrence of a Change of Control Triggering Event as provided in the indenture governing the notes. However, we may not have sufficient funds to repurchase the notes in cash at such time. In addition, our ability to repurchase the notes for cash may be limited by law or the terms of other agreements relating to our indebtedness outstanding at the time, which agreements may provide that a Change of Control Triggering Event constitutes an event of default or prepayment under such other indebtedness. Our failure to make such a repurchase would result in an event of default under your notes. See "Description of the Notes—Change of Control Offer."

**Changes in our credit ratings may adversely affect the value of the notes.** 

Our outstanding indebtedness, including the notes, may from time to time receive credit ratings from certain credit rating agencies. Such ratings are limited in scope and do not address all risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating was issued. An explanation of the significance of such ratings may be obtained from such rating agencies. Credit ratings are not a

------

##### [**Table of Contents**](#toc)
recommendation to buy, sell or hold the notes. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies or placed on a so-called "watch list" for a possible downgrade or assigned a negative ratings outlook if, in any rating agency's judgment, circumstances so warrant. In addition, because we may choose to take actions that adversely affect our credit ratings, such as incurring additional debt or repurchasing shares of our common stock, there can be no guarantee that our credit ratings will not decline during the term of the notes. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade or have been assigned a negative outlook, could adversely affect the market value of the notes and increase our borrowing costs.

**Our credit ratings may not reflect all risks of your investment in the notes.** 

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the notes.

These credit ratings may not reflect the potential impact of risks relating to structure or marketing of the notes. Agency ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization. Each agency's rating should be evaluated independently of any other agency's rating.

**There is no established trading market for the notes and one may not develop.** 

There is currently no established trading market for the notes, and we do not intend to apply for listing of the notes on any securities exchange or for inclusion of the notes in any automated quotation system. Although the underwriters have advised us that they presently intend to make a market in the notes after completion of the offering, they are under no obligation to do so and may discontinue any market-making activities at any time without notice. Accordingly, we cannot assure the liquidity of the trading market for the notes or that an active market will develop. If an active trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. Even if an active market does develop, the market may cease at any time. As a result, you may not be able to resell your notes for an extended period of time, if at all. In addition, if the notes are traded, they may trade at a discount from their initial offering price, depending on the market for similar securities, our results of operations and financial condition, general economic conditions and other factors.

**We may redeem your notes at our option, which may adversely affect your return.** 

As described under "Description of the Notes—Optional Redemption," we have the right to redeem the notes in whole or in part from time to time. We may choose to exercise this redemption right when prevailing interest rates are relatively low. As a result, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the notes.

**The notes do not contain restrictive financial covenants, and we may incur substantially more debt or take other actions which may affect our ability to satisfy our obligations under the notes.** 

Other than as described in this prospectus supplement under "Description of the Notes—Covenants" and "—Consolidation, Merger or Sale," the notes are not subject to any restrictive covenants, and we are not restricted from paying dividends or issuing or repurchasing our securities. In addition, the limited covenants applicable to the notes do not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations. Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the notes could have the effect of diminishing our ability to make payments on the notes when due, and require us to dedicate a substantial portion of our cash flow from operations to make payments on our indebtedness, which would reduce the availability of cash flow to fund our operations, working capital and capital expenditures.

------

##### [**Table of Contents**](#toc)
**We expect that the trading price of the notes will be significantly affected by changes in the interest rate environment, which could change substantially at any time.** 

We expect that the trading price of the notes will depend on a variety of factors, including, without limitation, the interest rate environment, which may be volatile, and is not within our control. If interest rates, or expected future interest rates, rise during the term of the notes, the market value of the notes may decline. Because interest rates and interest rate expectations are influenced by a wide variety of factors, many of which are beyond our control, we cannot assure you that changes in interest rates or interest rate expectations will not adversely affect the trading price of the notes.

**USE OF PROCEEDS** 

The net proceeds from this offering are estimated to be approximately $, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Concurrent with this offering, we have commenced the Tender Offer. We intend to use the net proceeds from this offering to fund the purchases of the 2028 Tender Offer Notes in the Tender Offer and to pay certain related fees and expenses. We intend to use any remaining net proceeds from this offering after completion of the Tender Offer for general corporate purposes.

In addition, BofA Securities, Inc. is acting as dealer manager in the Tender Offer. See "Underwriting."

**DESCRIPTION OF THE NOTES** 

**General** 

We will issue the notes under a fifth supplemental indenture to the indenture between us and the trustee, U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), dated February 14, 2012, as supplemented by the First Supplemental Indenture on February 14, 2012, the Second Supplemental Indenture on November 1, 2012, the Third Supplemental Indenture on June 7, 2018 and the Fourth Supplemental Indenture on February 23, 2021. References to the indenture in this section mean the indenture as so supplemented. If you would like to review the indenture and its supplements that we filed with the SEC, see "Where You Can Find More Information" in this prospectus supplement on how to locate the indenture and its supplements. You may also review the indenture and its supplements at the trustee's offices at U.S. Bank Trust Company, National Association, 1735 Market Street, 43rd Floor, Philadelphia, Pennsylvania 19103.

The following description of the notes supplements the description of the general terms and provisions of the Debt Securities in the accompanying prospectus. The following discussion summarizes selected provisions of the indenture. Because this is only a summary, it is not complete and does not describe every aspect of the notes and the indenture. You should read the indenture for provisions that may be important to you but which are not included in this summary. References to a supplemental indenture in the summary below refer to the fifth supplemental indenture that we will execute with the trustee relating to the notes offered by this prospectus supplement.

The indenture will not limit amount of notes that may be issued. The notes issued in this offering will be in an initial principal amount of $ million.

The notes will be denominated in U.S. dollars and we will pay principal and interest in U.S. dollars. The notes will not be subject to any conversion, amortization, or sinking fund. We will issue the notes only in fully registered book-entry form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof, except in the limited circumstances discussed below. You may transfer or exchange the notes without charge at the trustee's Corporate Trust Office in Pittsburgh, Pennsylvania, or at any other office or agency that we maintain for such purpose.

The indenture will permit us and our subsidiaries to incur additional secured and unsecured debt. Subject to the limitations described under the section "—Consolidation, Merger or Sale" and "—Change of Control Offer," the indenture will not contain any other provisions that would protect you from (1) a highly leveraged or similar transaction involving Kennametal; (2) a change of control; or (3) a reorganization, restructuring, merger or similar transaction involving Kennametal that may adversely affect you. In addition, subject to the limitations described in "—Consolidation, Merger or Sale," we may, in the future, sell all of our assets or merge or consolidate with another entity. Indebtedness which we would incur as a result of such a transaction could impair our ability to perform our obligations with respect to the notes.

In this "Description of the Notes" section, the terms "we," "us," the "Company," and "Kennametal" refer to Kennametal Inc. not including its subsidiaries and, whenever we talk about paying principal on the notes, we mean at maturity or redemption. Also, in discussing the time for notices and how the different interest rates are calculated, all times are New York City time, unless otherwise noted.

**Interest Rates and Maturity** 

The notes will bear interest at a rate of % per annum. In each case, the notes will bear interest from , 2026, or from the most recent interest payment date to which interest has been paid or duly provided for, and will be payable semi-annually in cash. We will pay interest on the notes on, to persons who were registered holders at the close of business on , and on , to persons who were registered

------

##### [**Table of Contents**](#toc)
holders at the close of business on , of each year. The first such payment will be made on , 2026. We will pay the principal and interest on the notes at an office or agency that we will maintain in Pittsburgh, Pennsylvania. However, we may pay such interest by check mailed to the holder at the address listed in the security register.

The notes mature on , 20 . The notes will not be subject to any sinking fund.

**Optional Redemption** 

Prior to , 20 (three months prior to the maturity date of the notes) (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 (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (i) the sum of the present values of the remaining scheduled payments of principal and interest thereon
discounted to the redemption date (assuming, for this purpose, that 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 (ii) interest accrued to the date of redemption, and

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

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, we may redeem the notes, 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 plus accrued and unpaid interest thereon to the redemption 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 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 (or in the case of a satisfaction and discharge, the third business day preceding any deposit of funds with the Trustee or paying agent) 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, 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, as applicable. If there is no

------

##### [**Table of Contents**](#toc)
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 the 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 deems appropriate and fair, and, in the case of Notes held by DTC (or another depositary), in accordance with the applicable policies and procedures of DTC (or the applicable depositary). 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. For any Notes held in certificated form, 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.

**Ranking** 

The notes are senior unsecured obligations and will rank equally with all our existing and future senior unsecured and unsubordinated indebtedness. A substantial portion of our business is conducted through subsidiaries and the notes will be effectively subordinated to all liabilities (including trade payables and guarantees) of our subsidiaries, including guarantees of existing and future bank credit facilities by certain of our domestic subsidiaries. At March 31, 2026, our subsidiaries had approximately $1.4 million of indebtedness, and had no secured indebtedness. As of March 31, 2026, we had $15.3 million of borrowings outstanding and had $634.7 million of available borrowing capacity under our existing Credit Agreement.

**Change of Control Offer** 

If a Change of Control Triggering Event (as defined below) occurs, each holder of the notes will have the right to require us to purchase all or a portion (equal to $2,000 principal amount and any integral multiples of $1,000 in excess thereof) of such holder's notes pursuant to the offer described below (a "Change of Control Offer") at a purchase price equal to 101% of the aggregate principal amount of the notes repurchased, plus accrued and unpaid interest, if any, to the date of repurchase (the "Change of Control Payment"), subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date.

------

##### [**Table of Contents**](#toc)
We will be required to send a notice to each holder of the notes by first-class mail, with a copy to the trustee, within 30 days following the date upon which any Change of Control Triggering Event occurred, or at our option, prior to any Change of Control (as defined below) but after the public announcement of the pending Change of Control. The notice will govern the terms of the Change of Control Offer and will describe, among other things, the transaction that constitutes or may constitute the Change of Control Triggering Event and the purchase date. The purchase date will be at least 30 days but no more than 60 days from the date such notice is mailed, other than as may be required by law (a "Change of Control Payment Date"). If the notice is mailed prior to the date of consummation of the Change of Control, the notice will state 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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• accept for payment all properly tendered notes or portions of notes not validly withdrawn;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• deposit with the paying agent the required payment for all properly tendered notes or portions of notes not
validly withdrawn; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• deliver or cause to be delivered to the trustee the repurchased notes, accompanied by an officers'
certificate stating, among other things, the aggregate principal amount of repurchased notes.

We will not be required to make a Change of Control Offer with respect to the notes upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by us and the third-party purchases all notes properly tendered and not withdrawn under its offer.

We will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable, in connection with the repurchase of notes as a result of a Change of Control Triggering 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.

Future debt of Kennametal may also prohibit Kennametal from purchasing notes in the event of a Change of Control, provide that a Change of Control is a default or require repurchase upon a Change of Control. Moreover, the exercise by the noteholders of their right to require Kennametal to purchase the notes could cause a default under other debt, even if the Change of Control itself does not, due to the financial effect of the purchase on Kennametal.

Finally, Kennametal's ability to pay cash to the noteholders following the occurrence of a Change of Control may be limited by Kennametal's then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make the required purchase of the notes. See "Risk Factors—We may not be able to repurchase all of the notes upon a Change of Control Triggering Event, which would result in an event of default under your notes."

Except as described above with respect to a Change of Control, the indenture does not contain provisions that permit the holder of the notes to require that Kennametal purchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

For purposes of the foregoing discussion, the following definitions apply:

"*Change of Control*" means the occurrence of any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or
consolidation), in one or more series of related transactions, of all or substantially all of our assets and the assets of our subsidiaries, taken as a whole, to any "person" (as that term is used in Section 13(d)(3) of the Exchange
Act), other than us or one of our subsidiaries;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the consummation of any transaction (including, without limitation, any merger or consolidation) the result of
which is that any "person" (as that term is used in Section 13(d)(3) of the Exchange Act), other than us or one of our subsidiaries, becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of more than 50% of our then outstanding Voting Stock or other Voting Stock into which our Voting Stock is reclassified, consolidated, exchanged or
changed, measured by voting power rather than number of shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Kennametal consolidates with, or merges with or into, any person, or any person consolidates with, or merges with
or into, Kennametal, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of Kennametal or such other person is converted into or exchanged for cash, securities or other property, other than any such transaction
where the shares of the Voting Stock of Kennametal 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; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the adoption of a plan relating to 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)(x) immediately following that transaction, 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 (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

"*Change of Control Triggering Event*" means the occurrence of both a Change of Control and a Rating Event (as defined below) that relates to such Change of Control.

"*Rating Agencies*" mean:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each of Moody's Investors Service, Inc., a subsidiary of Moody's Corporation, and its successors,
Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies, Inc., and its successors, and Fitch Ratings, Inc., and its successors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if any such Rating Agency ceases to rate the notes or fails to make a rating of the notes publicly available for
reasons outside of Kennametal's control, a substitute Rating Agency chosen by Kennametal.

"*Rating Event*" means with respect to a Change of Control, if the notes carry immediately prior to the first public announcement of the occurrence of such Change of Control or of the intention to effect such Change of Control:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an investment grade credit rating (BBB-/Baa3/BBB-, or equivalent, or better) from all of the Rating Agencies, and the rating from two of the three Rating Agencies is, within 60 days of the earlier of the
occurrence of such Change of Control or the first public announcement of the intention to effect such Change of Control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for possible
downgrade by any Rating Agency), either downgraded to a non-investment grade credit rating (BB+/Ba1 or equivalent, or worse) or withdrawn and is not within such period subsequently (in the case of a downgrade)
upgraded to an investment grade credit rating or (in the case of a withdrawal) replaced by an investment grade credit rating;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a non-investment grade credit rating (BB+/Ba1/BB+, or equivalent, or
worse) from all of the Rating Agencies, and the rating from two of the three Rating Agencies is, within 60 days of the earlier of the occurrence of such Change of Control or the first public announcement of the intention to effect such Change of
Control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for possible downgrade by any Rating Agency), either downgraded by one or more notches (for illustration, Ba1 to Ba2 being one
notch) or withdrawn and is not within such period subsequently upgraded to its earlier credit rating or better by both Rating Agencies;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• both an investment grade credit rating (BBB-/Baa3, or equivalent, or
better) from two Rating Agencies (a "pre-Change of Control Investment Grade Rating") and a non-investment grade credit rating (BB+/Ba1, or equivalent, or
worse) from one Rating Agency (a "pre-Change of Control Non-Investment Grade Rating"), and within 60 days of the earlier of the occurrence of such Change of
Control or the first public announcement of the intention to effect such Change of Control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for possible downgrade by any Rating
Agency) (x) the rating from the two Rating Agencies with an investment grade credit rating (BBB-/Baa3, or equivalent, or better) are both downgraded to a non-investment grade credit rating (BB+/Ba1, or equivalent, or worse) or withdrawn and are not within such period subsequently upgraded to their earlier credit rating or better by such Rating Agency (in the
case of a pre-Change of Control Investment Grade Rating) or (y) the rating from one of the two Rating Agencies with an investment grade credit rating (BBB-/Baa3, or
equivalent, or better) is downgraded to a non-investment grade credit rating (BB+/Ba1, or equivalent, or worse) or withdrawn and is not within such period subsequently upgraded to its earlier credit rating or
better by such Rating Agency (in the case of a pre-Change of Control Investment Grade Rating) and the rating from the Rating Agency with the non-investment grade credit
rating (BB+/Ba1, or equivalent, or worse) is further downgraded by one or more notches (for illustration, Ba1 to Ba2 being one notch) or withdrawn and is not within such period subsequently upgraded to its earlier credit rating or better by such
Rating Agency (in the case of a pre-Change of Control Non-Investment Grade Rating); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• both an investment grade credit rating (BBB-/Baa3, or equivalent, or
better) from one Rating Agency (a "pre-Change of Control Investment Grade Rating") and a non-investment grade credit rating (BB+/Ba1, or equivalent, or
worse) from two Rating Agencies (a "pre-Change of Control Non-Investment Grade Rating"), and within 60 days of the earlier of the occurrence of such Change
of Control or the first public announcement of the intention to effect such Change of Control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for possible downgrade by either Rating
Agency) (x) the rating from the two Rating Agencies with a non-investment grade credit rating (BB+/Ba1, or equivalent, or worse) are both downgraded by one or more notches (for illustration, Ba1 to Ba2
being one notch) or withdrawn and are not within such period subsequently upgraded to their earlier credit rating or better by such Rating Agency (in the case of a pre-Change of Control Non-Investment Grade Rating) or (y) the rating from the Rating Agency with an investment grade credit rating (BBB-/Baa3, or equivalent, or better) is downgraded to a non-investment grade credit rating (BB+/Ba1, or equivalent, or worse) or withdrawn and is not within such period subsequently upgraded to its earlier credit rating or better by such Rating Agency (in the case of a pre-Change of Control Investment Grade Rating) and one of the two ratings from the Rating Agencies with a non-investment grade credit rating (BB+/Ba1, or equivalent, or worse)
is further downgraded by one or more notches (for illustration, Ba1 to Ba2 being one notch) or withdrawn and is not within such period subsequently upgraded to its earlier credit rating or better by such Rating Agency (in the case of a pre-Change of Control Non-Investment Grade Rating);

provided that in making the relevant decision(s) referred to above to downgrade or withdraw such ratings, as applicable, the relevant Rating Agency announces publicly or confirms in writing to Kennametal that such decision(s) resulted, in whole or in part, from the occurrence of such Change of Control or the first public announcement of the intention to effect such Change of Control. We will provide the Trustee written notice of any Rating Event.

"Voting Stock" means, with respect to any specified person as of any date, the Capital Stock of such person (whether now or hereafter authorized, regardless of whether such Capital Stock shall be limited to a fixed sum or percentage with respect to the rights of the holders thereof to participate in dividends and in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of such corporation) that is at the time entitled to vote generally in the election of the board of directors of such person.

**Covenants** 

We covenant in the indenture that we will not and will not permit any of our Restricted Subsidiaries to:

(Limitation on Liens) create, incur or otherwise cause to exist or become effective any Liens (other than Permitted Liens) of any kind on any asset now owned or hereafter acquired without making effective provision whereby any and all notes then outstanding will be secured by a Lien equally and ratably with any and all other obligations thereby secured for so long as any such obligations are secured; or

(Limitation on Sale and Leaseback Transactions) enter into any sale and leaseback of a Principal Property (except for leases, including renewals, of five years or less) unless (1) either we or our Restricted Subsidiary is then permitted under the indenture as supplemented to incur Indebtedness secured by a Lien on such property or (2) within 180 days after such sale and leaseback, we apply to the voluntary retirement of funded debt an amount equal to the greater of the net proceeds of the sale of the property leased in the sale and leaseback or the fair value (in our opinion) of the leased property at the time we entered into such sale and leaseback.

The trustee may waive our compliance with these covenants if the holders of a majority in aggregate principal amount of the notes consent to the waiver. If we comply with the defeasance or covenant defeasance provisions of the indenture, we are not required to comply with such covenants.

**Key Definitions** 

"*Capitalized Lease Obligation*" means an obligation that is required to be classified and accounted for as a capitalized lease for financial reporting purposes in accordance with generally accepted accounting principles, and the amount of Indebtedness represented by such obligation shall be the capitalized amount of such obligation determined in accordance with such principles.

------

##### [**Table of Contents**](#toc)
legal liability; provided, that if the obligations so secured have not been assumed in full by such Person or are otherwise not such Person's legal liability in full, the amount of such indebtedness for the purposes of this definition shall be limited to the amount of such indebtedness secured by such Lien; (5) all indebtedness of others (including all interest and dividends on any Indebtedness or preferred stock of any other Person for the payment of which is) guaranteed, directly or indirectly, by such Person or that is otherwise its legal liability or which such Person has agreed to purchase or repurchase or in respect of which such Person has agreed contingently to supply or advance funds; and (6) obligations in respect of Currency Agreements and Interest Swap Obligations (as such capitalized terms are defined in the indenture). "*Issue Date*" shall mean the first date on which a note is authenticated by the trustee pursuant to the indenture.

"*Lien*" means any mortgage, pledge, security interest, encumbrance, lien, charge or adverse claim affecting title or resulting in an encumbrance against real or personal property or a security interest of any kind (including, without limitation, any conditional sale or other title retention agreement or lease in the nature thereof which is a Capitalized Lease Obligation).

"*Person*" means any individual, corporation, partnership, limited partnership, joint venture, association, joint-stock company, trust, unincorporated organization, government or any agency or political subdivision thereof, or any other entity.

"*Principal Property*" means any manufacturing plant or warehouse owned or leased by us or any of our Subsidiaries, the gross book value of which exceeds 4% of Consolidated Net Worth, other than manufacturing

------

##### [**Table of Contents**](#toc)
plants and warehouses which our Board of Directors by resolution declares, together with all other plants and warehouses previously so declared, is not of material importance to the total business conducted by us and our Restricted Subsidiaries as an entirety.

"*Property of any Person*" means all types of real, personal, tangible, intangible or mixed property owned by such Person whether or not included in our most recent consolidated balance sheet under generally accepted accounting principles.

"*Restricted Subsidiary*" means any of our Subsidiaries that is not an Unrestricted Subsidiary.

"*Subsidiary of any Person*" means (1) any Person of which more than 50% of the total voting power of shares of capital stock entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof is at the time owned or controlled, directly or indirectly, by any Person or one or more of the Restricted Subsidiaries of that Person or a combination thereof, and (2) any partnership, joint venture or other Person in which such Person or one or more of the Restricted Subsidiaries of that Person or a combination thereof has the power to control by contract or otherwise the board of directors or equivalent governing body or otherwise controls such entity.

Our Board of Directors may designate any Subsidiaries (including any newly-acquired or newly-formed Subsidiary) organized under the laws of a state of the United States or of the District of Columbia to be an Unrestricted Subsidiary unless such Subsidiary owns any capital stock of, or owns or holds any Property of, Kennametal or any other Restricted Subsidiary; provided, however, that the Subsidiary to be so designated has total assets of $35,000,000 or less.

**Consolidation, Merger or Sale** 

We may not merge or consolidate with any entity, sell or lease substantially all of our assets or assign our obligations under the indenture to another entity unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the successor entity is organized and exists under the laws of the United States, any state thereof, or the
District of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the successor entity expressly assumes our obligation to pay the principal, and premium, if any, and interest on
the notes and to perform and observe all the covenants and conditions of the indenture binding on us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• immediately after any such merger, consolidation, or sale, no default or event of default has occurred and is
continuing under the indenture.

What might constitute the sale of "all or substantially all" of our assets as used in the indenture varies according to the facts and circumstances of a particular sale transaction. This term has no clearly established meaning under New York law (which governs the indenture) and is subject to judicial interpretation. For these reasons, it may be unclear if a disposition of assets by us would be subject to this provision.

**Events of Default** 

An "Event of Default" occurs if

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) we default in the payment of interest on any note when the same becomes due and payable, and the default
continues for a period of 30 days;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) we default in the payment of the principal of any note when the same becomes due and payable at maturity, upon
acceleration or redemption, or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) we fail to make a Change of Control Offer and thereafter accept and pay for notes tendered when and as required
pursuant to "—Change of Control Offer";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) we fail to observe or perform in any material respect any of the other covenants, warranties or agreements in
the indenture or under the notes and the failure to observe or perform continues for a period of 90 days after receipt of written notice from the trustee or holders of at least 25% in aggregate principal amount of the outstanding notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) there is any default resulting in acceleration of other Indebtedness of Kennametal for borrowed money where the
aggregate principal amount so accelerated exceeds $50 million and such acceleration is not rescinded or annulled within 30 days after the written notice thereof to Kennametal by the trustee or to Kennametal and the trustee by the holders of 25%
in aggregate principal amount of the outstanding notes, provided that such Event of Default will be remedied, cured or waived if the default that resulted in the acceleration of such other Indebtedness is remedied, cured or waived; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) certain events in bankruptcy, insolvency or reorganization of Kennametal.

The holders of a majority in aggregate principal amount of the outstanding notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee. The trustee or the holders of not less than 25% in aggregate principal amount of the outstanding notes may declare the principal due and payable immediately upon an Event of Default (other than an Event of Default as specified in clause (6) of the Events of Default section herein).

If an Event of Default specified in clause (6) of the Events of Default section herein occurs, all the unpaid principal of and accrued interest on the outstanding notes (or specified principal amount) shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of any of the outstanding notes.

The holders of a majority in aggregate principal amount of the outstanding notes may annul such declaration and waive the default if the default (other than the non-payment of the principal of such series of notes which has become due solely by such acceleration) has been cured and a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been deposited with the trustee.

The holders of a majority in aggregate principal amount of outstanding notes affected thereby may, on behalf of the holders of all of the outstanding notes, waive any past default, except a default in the payment of principal or interest (unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been deposited with the trustee) or a default in respect of a covenant or provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding note.

Kennametal is required to file annually with the trustee a certificate as to whether or not Kennametal is in compliance with all the conditions and covenants applicable to it under the indenture.

**Modification of Indenture** 

From time to time, the indenture may be modified by Kennametal and the trustee without the consent of any holders of the notes with respect to certain matters, including (i) to cure any ambiguity, defect or inconsistency or to correct or supplement any provision which may be inconsistent with any other provision of the indenture, (ii) to qualify, or maintain the qualification of, the indenture under the Trust Indenture Act of 1939, as amended, and (iii) to make any change that does not materially adversely affect the interests of any holder of notes. In addition, under the indenture, certain rights, covenants and obligations of Kennametal and the rights of holders of notes may be modified by Kennametal and the trustee with the written consent of the holders of at least a

------

##### [**Table of Contents**](#toc)
majority in aggregate principal amount of the outstanding notes; but no extension of the maturity of the notes, reduction in the interest rate or extension of the time for payment of interest, change in the optional redemption or repurchase provisions in a manner adverse to any holder of notes, other modification in the terms of payment of the principal of, or interest on, the notes, or reduction of the percentage required for modification, will be effective against any holder of notes without such holder's consent.

In addition, Kennametal and the trustee may execute, without the consent of any holder of notes, any supplemental indenture for the purpose of creating any new series of debt securities.

**Defeasance and Covenant Defeasance** 

We may elect either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to terminate (and be deemed to have satisfied) all our obligations with respect to the notes (except for the
obligations to register the transfer or exchange of the notes, to replace mutilated, destroyed, lost or stolen notes, to maintain an office or agency in respect of the notes, to compensate and indemnify the trustee and to punctually pay or cause to
be paid the principal of and interest on and any other amounts payable in respect of all notes when due) ("defeasance"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to be released from our obligations with respect to certain covenants, including those described above under
"—Covenants" ("covenant defeasance")

upon the deposit with the trustee (and in the case of a defeasance, 121 days after such defeasance), in trust for such purpose, of money and/or U.S. Government Obligations (as defined in the indenture) which through the payment of principal and interest 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 the principal of, interest on and any other amounts payable in respect of the outstanding notes. Such a trust may be established only if, among other things, we have delivered to the trustee an opinion of counsel (as specified in the indenture) with regard to certain matters, including an opinion (in the case of a defeasance, based upon a ruling from the Internal Revenue Service or a change in applicable tax law occurring after the date of the indenture) that the beneficial owners of the notes will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance or covenant defeasance had not occurred.

**Further Issuances** 

We may from time to time, without notice to or the consent of the registered holders of the notes, create and issue further notes ranking equally and ratably with the notes in all respects (or in all respects except for the payment of interest accruing prior to the issue date of such further notes or except for the first payment of interest following the issue date of such further notes), so that such further notes shall be consolidated and form a single series with the notes and shall have the same terms as to status, redemption or otherwise as the notes; provided that if such further notes are not fungible with the notes for U.S. federal income tax purposes, such further notes will have a separate CUSIP number.

**Book-Entry Notes—Registration, Transfer and Payment of Interest and Principal** 

Book-entry notes will be issued in the form of global notes that will be deposited with The Depository Trust Company, New York, New York, or DTC, and will be registered in the name of Cede & Co. (DTC's nominee). The deposit of global notes with, or on behalf of, DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the global notes representing the notes. DTC's records reflect only the identity of its participants to whose accounts the notes are credited, which may or may not be the beneficial owners. The direct participant remains responsible for keeping account of its holdings on behalf of its customers.

------

##### [**Table of Contents**](#toc)
Conveyance of notices and other communications by DTC to its participants and by its participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect.

This means that we will not issue certificates to each actual purchaser of the notes. Only direct participants in DTC may purchase under DTC's system. One global note for the notes will be issued and deposited with DTC, who will keep a computerized record of its participants (for example, your broker) whose clients have purchased the notes. The participant will then keep a record of its clients who purchased the notes. Beneficial owners are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings from the direct participant in DTC. Unless it is exchanged in whole or in part for a certificated note, a global note may not be transferred; except that DTC, its nominees, and their successors may transfer a global note as a whole to one another.

Beneficial interests in global notes will be shown on, and transfers of global notes will be made only through, records maintained by DTC and its participants. Beneficial owners of interests in the global notes must rely on DTC's procedures. Beneficial owners who are not direct participants in DTC must rely on the direct participant's procedures in order to exercise such owner's rights under the global note or the indenture and its supplement. The laws of some jurisdictions require certain purchasers of securities to take physical delivery of such securities in certificated form. Such laws may impair your ability to transfer beneficial interests in a global note representing the notes.

DTC has provided us the following information regarding DTC.

DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the United States Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered under the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants deposit with DTC. DTC also records the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through computerized records for its participants' accounts. This eliminates the need to exchange certificates. The participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.

DTC's book-entry system is also used by other organizations such as securities brokers and dealers, and banks and trust companies that work through a direct participant in DTC. The rules that apply to DTC and its participants are on file with the SEC.

DTC is owned by a number of its direct participants and by the New York Stock Exchange, Inc., The American Stock Exchange, Inc. and the Financial Industry Regulatory Authority, Inc.

We will wire principal and interest payments to DTC's nominee. The trustee and we will treat DTC's nominee as the owner of the global notes for all purposes. Accordingly, we, the trustee and any paying agent will have no direct responsibility or liability to pay amounts due on the global notes to owners of beneficial interests in the global notes.

It is DTC's current practice, upon the date of payment of principal or interest, to credit its direct participants' accounts on the payment date according to their respective holdings of beneficial interests in the global notes as shown on DTC's records unless DTC believes that it will not receive payment on the payment date. In addition, it is DTC's current practice to assign any consenting or voting rights of Cede & Co., as DTC's nominee, to its direct participants whose accounts are credited with notes on a record date, by using an omnibus proxy. Neither DTC nor Cede & Co. will consent or vote with respect to the global notes. Payments by participants to owners of beneficial interests in the global notes will be governed by the customary practices between the participants and owners of beneficial interests, as is the case with notes held for the account of customers registered in "street name." However, payments to the owners of the beneficial interests will be the responsibility of the participants and not of DTC, the trustee or us.

------

##### [**Table of Contents**](#toc)
Notes represented by a global note will be exchangeable for certificated notes with the same terms in authorized denominations only if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• DTC notifies us that DTC is unwilling or unable to continue as depositary or if DTC ceases to be a clearing
agency registered under applicable law and a successor depositary is not appointed by us within 90 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an Event of Default exists under the indenture and its supplement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we determine that the global notes will be exchanged for certificated notes and notify the trustee of our
decision.

**Certificated Notes—Registration, Transfer, and Payment of Interest and Principal** 

If we issue certificated notes, they will be registered in the name of the noteholder. We will obtain the name of the noteholder from DTC's participants. The notes may be transferred or exchanged, pursuant to administrative procedures in the indenture, without the payment of any service charge (other than any tax or other governmental charge) by contacting the paying agent.

Holders can request that payment of principal and interest be wired to them by contacting the paying agent at least one business day prior to the payment date.

The underwriters will make settlement for the notes in immediately available funds. We will make all payments of principal and interest in immediately available funds. The notes will trade in DTC's Same-Day Funds Settlement System until maturity, and secondary market trading activity in the notes will be required by DTC to settle in immediately available funds.

**Governing Law** 

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

**The Trustee** 

U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association) is the trustee under the indenture and will be the trustee under the supplemental indenture.

**CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS** 

The following discussion is a summary of certain material U.S. federal income tax considerations relevant to the acquisition, ownership, and disposition of the notes. This discussion only applies to notes that are held as capital assets, within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"), and that are purchased in the initial offering at the initial offering price, by U.S. Holders and Non-U.S. Holders (each as defined below). This discussion is based on interpretations of the Code, Treasury regulations issued thereunder, and rulings and decisions currently in effect, all of which are subject to change. Any such change may be applied retroactively and may adversely affect the U.S. federal income tax considerations described herein.

This summary does not discuss all U.S. federal income tax considerations that may be relevant to U.S. Holders and Non-U.S. Holders in light of their particular circumstances or that may be relevant to certain holders that may be subject to special treatment under U.S. federal income tax law (for example, tax-exempt organizations, insurance companies, banks and other financial institutions, dealers in securities, traders in securities that elect to use a mark-to-market method of accounting, real estate investment trusts, regulated investment companies, individual retirement accounts, qualified pension plans, individuals who are former citizens or former residents of the United States, holders of 2028 Tender Offer Notes, persons who hold the notes as part of a straddle, hedging, constructive sale, conversion, or other integrated transaction, U.S. Holders whose functional currency is not the U.S. dollar, controlled foreign corporations, passive foreign investment companies, corporations that accumulate earnings to avoid U.S. federal income tax, or 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). Furthermore, this summary does not discuss any alternative minimum tax considerations, and does not address any aspects of federal non-income taxation or state, local, or foreign taxation.

As used in this discussion, the term "U.S. Holder" means a beneficial owner of the notes that is, for U.S. federal income tax purposes (a) an individual who is a citizen or resident of the United States, (b) a corporation organized under the laws of the United States, any state thereof, or the District of Columbia, or is otherwise treated as a domestic corporation, (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (d) a trust (i) whose administration is subject to the primary supervision of a court within the United States and all substantial decisions of which are subject to the control of one or more United States persons as described in Section 7701(a)(30) of the Code (each, a "United States person"), or (ii) that has a valid election in effect under applicable Treasury regulations to be treated as a United States person.

A "Non-U.S. Holder" means a beneficial owner of notes that is not a U.S. Holder and is not a partnership (including any entity or arrangement properly classified as a partnership for U.S. federal income tax purposes).

If a partnership (including an entity or arrangement properly classified as a partnership for U.S. federal income tax purposes) holds notes, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. Partners of a partnership holding the notes should consult their own tax advisors.

No ruling has been or will be obtained from the Internal Revenue Service (the "IRS") with respect to the matters discussed below. As a result, no assurance can be given that the IRS will not assert, or that a court will not sustain, a position contrary to the conclusions set forth below.

**This discussion does not address all of the U.S. federal income tax consequences that may be relevant to holders in light of their particular circumstances or to investors subject to special treatment under U.S. federal income tax laws, nor does it deal with federal non-income taxation or the tax consequences under the laws of any foreign, state or local taxing jurisdictions. Accordingly, prospective investors are urged to consult their own tax advisors with respect to the U.S. federal, state and local tax consequences of investing in the notes, as well as any consequences arising under the laws of any other taxing jurisdiction to which they may be subject.**

**Effect of Certain Contingent Payments** 

In certain circumstances, we may be obligated to make payments on the notes in excess of stated interest and principal, or prior to their scheduled payment dates (see "Description of the Notes—Change of Control Offer"). Treasury regulations provide special rules for the treatment of debt instruments that provide for contingent payments. Under these regulations, a contingency is disregarded if the contingency is remote or incidental. We believe that the likelihood that we will make any of the above payments is remote or incidental and we intend to take the position that the notes are not contingent payment debt instruments under applicable Treasury regulations. A successful challenge of this position by the IRS could affect the timing and amount of income inclusions with respect to the notes, and could also cause any gain from the sale or other disposition of a note to be treated as ordinary income rather than as capital gain. Our position is binding on a beneficial owner of a note, unless the beneficial owner discloses in the proper manner to the IRS that it is taking a different position.

Beneficial owners of the notes should consult their own tax advisors regarding the possible application of the contingent payment debt instrument rules to the notes. The remainder of this summary assumes that the notes will not be considered to be contingent payment debt instruments.

**U.S. Holders** 

***Interest on the Notes***

Interest payments on the notes will be taxable to a U.S. Holder as ordinary income at the time such interest is received or accrued, in accordance with the U.S. Holder's regular method of accounting for U.S. federal income tax purposes. The notes are not expected to be issued with an amount equal to or greater than *de minimis* original issue discount ("OID"). However, if the notes are issued at a discount that will equal or exceed *de minimis* OID, each U.S. Holder generally will be required to include OID in income (as interest) as it accrues, regardless of its regular method of accounting for U.S. federal income tax purposes, using a constant yield method, before such U.S. Holder receives any payment attributable to such income. The remainder of this discussion assumes that the notes are not issued with an amount equal to or greater than *de minimis* OID.

***Sale, Exchange, Redemption or Other Taxable Disposition of the Notes***

Upon the sale, exchange, redemption or other taxable disposition of a note, a U.S. Holder generally will recognize a gain or loss in an amount equal to the difference between the amount realized (other than any amount representing accrued but unpaid interest, which will be treated as ordinary income to the extent not previously included in income) and the U.S. Holder's adjusted tax basis in the note. The amount realized by a U.S. Holder will be the sum of the cash plus the fair market value of all other property received on such sale, exchange, redemption or other taxable disposition. A U.S. Holder's adjusted tax basis in a note generally will equal the purchase price of the note.

Any gain or loss so recognized generally will be capital gain or loss and will be long-term capital gain or loss if such U.S. Holder has held such note for more than one year at the time of such sale, exchange, redemption or other taxable disposition. Net long-term capital gain of certain non-corporate U.S. Holders (including individuals) generally is subject to preferential rates of U.S. federal income tax. The deductibility of capital losses is subject to limitations.

***Net Investment Income Tax***

U.S. Holders who are individuals, estates or certain trusts may be subject to a 3.8% net investment income tax on the lesser of (1) the U.S. person's "net investment income" for the relevant taxable year and (2) the excess of the U.S. person's modified gross income for the taxable year over certain thresholds that vary depending on the individual's circumstances. Net investment income generally will include interest income and net gains from the disposition of the notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). A U.S. Holder that is an individual, estate or trust should consult its tax advisor regarding the applicability of the net investment income tax to its interest income and gains in respect of its investment in the notes.

***Backup Withholding and Information Reporting***

In general, a U.S. Holder that is not an "exempt recipient" will be subject to U.S. federal backup withholding tax at the applicable rate with respect to payments on the notes and the proceeds of a sale, exchange, redemption or other taxable disposition of the notes, unless the U.S. Holder provides its taxpayer identification number to the applicable withholding agent and certifies, under penalty of perjury, that it is not subject to backup withholding on IRS Form W-9 or an applicable successor form and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder may be allowed as a credit against such U.S. Holder's U.S. federal income tax liability and may entitle such U.S. Holder to a refund, provided the required information is furnished to the IRS in a timely manner.

In addition, payments on the notes made to, and the proceeds of a sale, exchange, redemption or other taxable disposition by, a U.S. Holder generally will be subject to information reporting requirements, unless such U.S. Holder is an exempt recipient and appropriately establishes that exemption.

**Non-U.S. Holders** 

***Interest on the Notes***

Subject to the discussions below under "—Backup Withholding and Information Reporting" and "—Foreign Account Tax Compliance Act", interest payments on the notes to Non-U.S. Holders generally will not be subject to U.S. federal income or withholding tax if the following conditions are satisfied:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 stock entitled to vote within the meaning of Section 871(h)(3) of the Code,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Non-U.S. Holder is not a controlled foreign corporation for U.S.
federal income tax purposes that is related to us through actual or constructive ownership,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such interest is not effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (or, in the case of an applicable income tax treaty, is not attributable to a permanent establishment or a fixed base that the Non-U.S. Holder maintains in the United States), and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• either (a) the Non-U.S. Holder provides a correct, complete and
executed IRS Form W-8BEN, Form W-8BEN-E, Form W-8EXP or Form W-8IMY (or suitable successor or substitute form) with all of the attachments required by the IRS or (b) the Non-U.S. Holder holds its notes through a qualified
intermediary (generally a foreign financial institution or clearing organization or a non-U.S. branch or office of a U.S. financial institution or clearing organization that is a party to a withholding
agreement with the IRS), which has provided an IRS Form W-8IMY (or suitable successor or substitute form) stating that it is a qualified intermediary and has received documentation upon which it can rely to
treat the payment as made to a foreign person.

If any of the conditions described above are not satisfied, interest on the notes will be subject to a 30% withholding tax when paid, unless either the Non-U.S. Holder provides a correct, complete and executed IRS Form W-8BEN or Form W-8BEN-E claiming that an income tax treaty reduces or eliminates the tax, or the interest is effectively connected with the conduct of a U.S. trade or business and the Non-U.S. Holder provides a correct, complete and executed IRS Form W-8ECI. If interest is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (or, in the case of an applicable income tax treaty, is attributable to a permanent establishment or a fixed base that the Non-U.S. Holder maintains in the United States), Non-U.S. Holders generally will be subject to U.S. federal income tax with respect to all income from the notes in the same manner as a United States person. In addition, Non-U.S. Holders that are corporations could be subject to a 30% branch profits tax on such income.

***Sale, Exchange, Redemption or Other Taxable Disposition of the Notes***

Subject to the discussions below under "—Backup Withholding and Information Reporting" and "—Foreign Account Tax Compliance Act", gain realized on the sale, exchange, redemption or other taxable disposition of the notes by a Non-U.S. Holder generally will not be subject to U.S. federal income tax, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the gain with respect to the notes is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or a fixed base that the Non-U.S. Holder maintains in the U.S.), in which case the gain will be taxed in the same manner as interest that is effectively connected to such trade or business, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Non-U.S. Holder is a nonresident alien individual who holds the notes
as a capital asset and is present in the United States for more than 182 days in the taxable year of the sale, exchange, redemption or other taxable disposition of the notes and certain other conditions are satisfied, in which case the gain will be
subject to a 30% tax (or a lower rate under an applicable income tax treaty).

To the extent the amount realized on a sale, exchange, redemption or other taxable disposition of the notes is attributable to accrued but unpaid interest on the notes, such amount generally will be subject to, or exempt from, tax to the same extent as described above under "—Interest on the Notes."

***Backup Withholding and Information Reporting***

Backup withholding will not be required with respect to interest paid to Non-U.S. Holders, so long as the applicable withholding agent has received from the Non-U.S. Holder a correct and complete IRS Form W-8BEN, Form W-8BEN-E, Form W-8ECI, Form W-8EXP or Form W-8IMY (or suitable successor or substitute form) with all of the attachments required by the IRS and provided that the applicable withholding agent does not have actual knowledge or reason to know that the Non-U.S. Holder is a United States person. Interest paid to a Non-U.S. Holder will be reported on IRS Form 1042-S, which is filed with the IRS and sent to Non-U.S. Holders.

Information reporting and backup withholding may apply to the proceeds of a sale of the notes by a Non-U.S. Holder made within the United States or conducted through certain U.S. related financial intermediaries, unless the applicable withholding agent receives one of the IRS tax forms described above and provided that the applicable withholding agent does not have actual knowledge or reason to know that the Non-U.S. Holder is a United States person.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder may be allowed as a credit against such Non-U.S. Holder's U.S. federal income tax liability and may entitle such Non-U.S. Holder to a refund, provided the required information is furnished to the IRS in a timely manner. The information reporting requirements may apply regardless of whether withholding is required. For Non-U.S. Holders, copies of the information returns reporting such interest and withholding also may be made available to the tax authorities in the country in which a Non-U.S. Holder is a resident under the provisions of an applicable income tax treaty or agreement.

***Foreign Account Tax Compliance Act***

Under Sections 1471 to 1474 of the Code, enacted under the "Foreign Account Tax Compliance Act" ("FATCA") and guidance issued by the IRS, a U.S. federal withholding tax of 30% generally applies to interest on a debt obligation, including a note, paid to certain non-United States entities (including, in some circumstances, where such an entity is acting as an intermediary) that fail to comply with certain certification and information reporting requirements. Although withholding under FATCA would have applied to payments of gross proceeds from the sale, exchange, redemption or other taxable disposition of the notes on or after

------

##### [**Table of Contents**](#toc)
January 1, 2019, 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. If an interest payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under "—Interest on the Notes," the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Prospective holders of the notes should consult their own tax advisors regarding the effect, if any, of the FATCA rules for them based on their particular circumstances.

**UNDERWRITING** 

BofA Securities, Inc., BNP Paribas Securities Corp., and PNC Capital Markets LLC are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of notes set forth opposite its name below.

|  BofA Securities, Inc. | $|
|  BNP Paribas Securities Corp. |  |
|  PNC Capital Markets LLC |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Total | $|

---

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

**Discounts** 

The representatives have advised us that the underwriters propose initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of % of the principal amount of the notes. In addition, the underwriters may allow, and those selected dealers may reallow, a concession not in excess of % of the principal amount of the notes to certain other dealers. After the initial offering, the public offering price, concessions or any other term of the offering may be changed.

The expenses of the offering (which include legal fees and expenses, accounting fees and expenses, SEC filing fees, printing fees and rating agency fees, but not including the underwriting discount) are estimated at $ and are payable by us.

**New Issue of Notes** 

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded,

------

##### [**Table of Contents**](#toc)
they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

**No Sales of Similar Securities** 

We have agreed that we will not, during the period from the date of this prospectus supplement through the closing date, without first obtaining the prior written consent of the representatives, directly or indirectly, issue, sell, offer to contract or grant any option to sell, pledge, transfer or otherwise dispose of, any debt securities or securities exchangeable for or convertible into debt securities, except for the notes sold to the underwriters pursuant to the underwriting agreement.

**Short Positions** 

Similar to other purchase transactions, the underwriters' purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

**Other Relationships** 

Certain of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

Affiliates of certain of the underwriters are lenders and perform other roles under our revolving credit facility. In addition, BofA Securities, Inc. is acting as dealer manager in the Tender Offer.

In addition, in the ordinary course of their business activities, the underwriters and their 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates 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, these 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 affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. the aggregate consideration payable on acceptance of the offer or invitation by each offeree or invitee is at
least A$500,000 (or its equivalent in another currency, in either case, disregarding moneys lent by the person offering the notes or making the invitation or its associates) or the offer or invitation otherwise does not require disclosure to
investors in accordance with Part 6D.2 or 7.9 of the Corporations Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. the offer, invitation or distribution complied with the conditions of the Australian financial services license

------

##### [**Table of Contents**](#toc)

(including, without limitation, the licensing requirements set out in Chapter 7 of the Corporations Act);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. the offer or invitation does not constitute an offer or invitation to a person in Australia who is a
"retail client" as defined for the purposes of Section 761G of the Corporations Act; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v. such action does not require any document to be lodged with ASIC or the ASX.

**T+ Settlement** 

It is expected that delivery of the notes will be made to investors on or about May , 2026, which will be the business day following the date hereof (such settlement cycle being referred to as "T+ "). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing or on any subsequent date that is prior to the first trading day preceding the date on which we deliver the notes to the underwriters for the offering will be required, by virtue of the fact that the notes initially will settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement and should consult their own advisors.

**ABOUT THIS PROSPECTUS** 

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the "SEC"), as a "well-known seasoned issuer," as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act") using the shelf registration process. Under this shelf registration process, we may sell, from time to time, an indeterminate amount of any combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement, which may be in the form a term sheet, or other offering material that will contain specific information about the terms of that offering, including the specific amounts, prices and terms of the securities offered. The prospectus supplement and any other offering material may also add to, update or change information contained in this prospectus and accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in the prospectus supplement. We urge you to read both this prospectus and any accompanying prospectus supplement, together with additional information described under the heading "Where You Can Find More Information" before making an investment decision.

The prospectus supplement will describe: the terms of the securities offered, the initial public offering price, the price paid to us for the securities, the net proceeds to us, the manner of distribution and any underwriting compensation and the other specific material terms related to the offering of the securities. For more detail about the terms of the securities, you should read the exhibits filed with or incorporated by reference in our registration statement of which this prospectus forms a part.

This prospectus contains summaries of certain provisions contained in some of the documents described herein, but reference is made to the actual documents for complete information. All of the summaries are qualified in their entirety by the actual documents. Copies of the documents referred to herein have been filed, or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and you may obtain copies of those documents as described below under "Where You Can Find More Information".

Because we are a well-known seasoned issuer, as defined in Rule 405 of the Securities Act, we may add to and offer additional securities, including those to be sold by security holders, by filing a prospectus supplement with the SEC at the time of the offering.

We have not authorized any person to provide you with any information or to make any representation other than as contained in this prospectus or in any prospectus supplement and the information incorporated by reference herein and therein. We do not take any responsibility for, and can provide no assurance as to the reliability of, any information that others may provide you. The information appearing or incorporated by reference in this prospectus and any accompanying prospectus supplement is accurate only as of the date of this prospectus or any accompanying prospectus supplement or the date of the document in which incorporated information appears. Our business, financial condition, results of operations and prospects may have changed since those dates.

We are not making an offer to sell or soliciting an offer to purchase these securities in any jurisdiction where the offer or sale is not permitted.

Except as otherwise specifically noted or unless the context requires otherwise, the terms "we," "our" and "us" refer to Kennametal Inc. and its subsidiaries.

**USE OF PROCEEDS** 

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from the sale of the securities for general corporate purposes, which may include, without limitation, working capital, acquisitions, retirement of outstanding debt, capital expenditures and other business opportunities or such other purposes as may be specified in the applicable prospectus supplement relating to such offering.

##### [**Table of Contents**](#toc)
**DESCRIPTION OF SECURITIES** 

The following description summarizes the general terms and provisions of the securities that Kennametal may offer from time to time pursuant to this prospectus. These summaries are not a complete description of each security. At the time of an offering and sale, this prospectus together with the accompanying prospectus supplement will contain the material terms of the securities being offered. In this section, "Kennametal" refers to Kennametal, excluding its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

**DESCRIPTION OF KENNAMETAL CAPITAL STOCK** 

The following summary of the terms of Kennametal's capital stock is not complete and is subject to and qualified in its entirety by reference to the relevant provisions of the laws of the Commonwealth of Pennsylvania, our Amended and Restated Articles of Incorporation (the "Articles"), and our Amended and Restated Bylaws (the "Bylaws"). Copies of the Articles and Bylaws have been filed with the SEC, are incorporated herein by reference. See "Where you can find more information."

**General** 

Our authorized capital stock consists of 120,000,000 shares of capital stock, par value $1.25 per share (the "common stock"), and 5,000,000 shares of Class A Preferred Stock, without par value (the "preferred stock"). The rights and preferences of the preferred stock may be established from time to time by our board of directors (the "Board of Directors" or "Board"). As of July 31, 2024, 77,900,791 shares of common stock were outstanding and were held by approximately 1,252 record holders. No shares of preferred stock were issued or outstanding as of July 31, 2024.

**Common Stock** 

Each share of our common stock is entitled to one vote on all matters requiring a vote of shareholders and, subject to the rights of the holders of any outstanding shares of preferred stock, each shareholder is entitled to receive any dividends, in cash, securities or property, as our Board may declare. Pennsylvania law prohibits the payment of dividends or the repurchase of our shares if we are insolvent or if we would become insolvent after the dividend or repurchase. In the event of our liquidation, dissolution or winding up, either voluntarily or involuntarily, subject to the rights of the holders of any outstanding shares of preferred stock, holders of common stock are entitled to share pro-rata in all of our remaining assets available for distribution. Any common stock issued pursuant to this prospectus will, when issued, be fully paid and nonassessable and will not have, or be subject to, any preemptive or similar rights.

**Preferred Stock** 

Under the laws of the Commonwealth of Pennsylvania and the Articles, the Board of Directors, without further action by the shareholders, is authorized to designate and issue, at any time or from time to time, one or more series of preferred stock, to fix and determine the number of shares and the designation of such series, and to fix and determine the voting rights, preferences, qualifications, privileges, limitations, options, conversion rights, restrictions, and other special or relative rights of such series.

If we issue preferred stock, it may rank senior to the common stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up, or both. In addition, shares of preferred stock may have class or series voting rights. Issuances of preferred stock, while providing us with flexibility in connection with general corporate purposes, may, among other things, have an adverse effect on the rights of holders of common stock. Other than as provided by law, in the Articles, in the Bylaws, or in a resolution or resolutions establishing any particular series of preferred stock, the aggregate number of authorized shares of preferred stock may be increased by an amendment to the Articles approved solely by a majority vote of the outstanding shares of common stock.

##### [**Table of Contents**](#toc)
**Anti-Takeover Provisions in our Articles and Bylaws** 

Certain provisions of the Articles and Bylaws could have an anti-takeover effect. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our Board of Directors and in the strategies it formulates. These provisions may also discourage an unsolicited takeover of us if the Board of Directors determines that the takeover is not in the best interests of us and our shareholders. These provisions could have the effect of discouraging certain attempts to acquire us or remove incumbent management even if some or a majority of shareholders deemed such an attempt to be in their best interests.

The provisions in the Articles and Bylaws include: (i) a procedure which requires shareholders to nominate directors in advance of a meeting to elect such directors; and (ii) the authority to issue additional shares of common stock or preferred stock without shareholder approval.

The Articles also include a provision requiring the affirmative vote of the holders of 75% of our outstanding stock to approve certain mergers or other business combinations or transactions with five percent shareholders; a provision requiring the affirmative vote of the holders of 75% of our outstanding stock to remove the entire Board of Directors, a class of the Board of Directors, any individual member of the Board of Directors without cause, or to increase the size of the Board of Directors to more than twelve members or decrease the size of the Board of Directors to fewer than eight members; a provision requiring, in the case of repurchases at a premium over market by us from any 4% Shareholder (as defined in the Articles), the affirmative vote of the holders of voting power of an amount of shares equal to the voting power of the 4% Shareholder plus a majority of the voting power of the other shares not held by the 4% Shareholder (subject to limited exceptions); and a provision requiring the affirmative vote of a majority of our outstanding stock held by disinterested shareholders to approve certain business combinations involving a shareholder who beneficially owns more than 10% of the voting power of our then outstanding voting stock, unless certain conditions are satisfied or the transaction is approved by a majority of disinterested directors.

Pursuant to the Articles and the laws of the Commonwealth of Pennsylvania, the Board of Directors is permitted to consider the effects of a change in control on our non-shareholder constituencies, such as our employees, suppliers, and other constituents and the communities in which we operate. Pursuant to this provision, the Board of Directors may be guided by factors in addition to price and other financial considerations.

The Bylaws provide that any shareholder who desires to present a nomination of person(s) for election to the Board of Directors or a proposal of other business at a shareholders' meeting (a "Proponent") must first provide timely written notice to the Secretary. The Bylaws set forth the deadlines for submitting such advance notice. As described in the Bylaws, the advance notice must set forth in reasonable detail (i) as to each person the shareholder proposes to nominate for election to the Board of Directors, information concerning the proposed nominee that would be required to be disclosed in a proxy statement or other filings required to be made in connection with the solicitation of proxies for the election of directors in an election contest, or otherwise required, in each case pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder, including such nominee's consent to serve as a director if elected and other specific information called for by the Bylaws, or (ii) as to any other business that the Proponent proposes to bring before the meeting, a description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the Bylaws, the language of the proposed amendment), the reasons for conducting such business at the meeting, and any material interest in such business of the Proponent and the beneficial owner, if any, on whose behalf the proposal is made. The advance notice must also include a representation from the Proponent that such person is a shareholder of record and intends to appear in person or by proxy at the meeting to present the nomination or other proposal specified in the notice, a description of the Proponent's beneficial ownership and other financial interests in Kennametal, a description of all arrangements or understandings between the Proponent and any other person or persons (naming such persons) pursuant to which the nomination or other proposal is to be made by the Proponent, and all such information regarding the Proponent's proposal

and/or nominee(s) which would have been required to be included in a proxy statement filed pursuant to the proxy rules of the SEC had the nomination or other proposal been made by the Board of Directors.

**PBCL Anti-Takeover Provisions** 

The Pennsylvania Business Corporation Law (the "PBCL") contains a number of statutory "anti-takeover" provisions, including Subchapters E, F, G and H of Chapter 25 and Sections 2521, 2524 and 2538 of the PBCL, which apply automatically to a Pennsylvania registered corporation (usually a public company) unless the corporation elects to opt-out of those provisions. We are a Pennsylvania registered corporation, and as a result we are subject to the anti-takeover provisions described below, however, we have elected to opt-out of certain provisions as described below. Descriptions of the anti-takeover provisions are qualified in their entirety by reference to the PBCL.

Subchapter E (relating to control transactions) generally provides that if any person or group acquires 20% or more of our voting power, the remaining holders of voting shares may demand from such person or group the fair value of their voting shares, including a proportionate amount of any control premium.

Subchapter F (relating to business combinations) generally delays for five years and imposes conditions upon "business combinations" between an "interested shareholder" and us. The term "business combination" is defined broadly to include various transactions between a corporation and an interested shareholder including mergers, sales or leases of specified amounts of assets, liquidations, reclassifications and issuances of specified amounts of additional shares of stock of the corporation. An "interested shareholder" is defined generally as the beneficial owner of at least 20% of a corporation's voting shares.

Section 2521 of the PBCL generally provides that shareholders are not entitled to call special meetings of the shareholders and our Bylaws do not give shareholders any right to call special meetings.

Section 2524 provides that shareholders cannot act by partial written consent unless permitted in the articles of incorporation.

Section 2538 of the PBCL generally establishes certain shareholder approval requirements with respect to specified transactions with "interested shareholders."

We have elected to opt out of Subchapters G and H of Chapter 25 of the PBCL. Subchapter G would have required a shareholder vote to accord voting rights to control shares acquired by a 20% shareholder in a control-share acquisition. Subchapter H would have required a person or group to disgorge to us any profits received from a sale of our equity securities within 18 months after the person or group acquired, offered to acquire or publicly disclosed an intention to acquire 20% of our voting power or publicly disclosed an intention to acquire control of us.

**Transfer Agent and Registrar**

**DESCRIPTION OF DEBT SECURITIES** 

As used in this prospectus, debt securities means the debentures, notes, bonds and other evidences of indebtedness that we may issue separately, upon exercise of a debt warrant, in connection with a purchase contract or as part of a unit, from time to time. The debt securities may either be senior debt securities or subordinated debt securities. As required by federal law for all debt securities of companies that are publicly offered, the debt securities will be governed by a document called an "indenture." An indenture is a contract between a financial institution, acting on your behalf as trustee of the debt securities offered, and Kennametal. Unless otherwise specified in the applicable prospectus supplement, senior debt securities will be issued under the Indenture, dated as of February 14, 2012, between Kennametal and U.S. Bank National Association, as trustee (the "Senior Indenture"), and subordinated debt securities may be issued under a "Subordinated Indenture" expected to be entered into between Kennametal and U.S. Bank National Association, as trustee (the "Subordinated Indenture"). The trustee has two main roles. First, subject to certain limitations on the extent to which the trustee can act on your behalf, the trustee can enforce your rights against Kennametal if Kennametal defaults on its obligations under the indenture. Second, the trustee performs certain administrative duties for Kennametal with respect to the debt securities. The indenture is subject to and governed by the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The Senior Indenture and the form of the Subordinated Indenture have been filed with the SEC as an exhibit to the registration statement of which this of prospectus is a part and are incorporated by reference in the registration statement. When Kennametal refers to the "indenture" in this prospectus, it is referring to the indenture under which your debt securities are issued, as may be supplemented by any supplemental indenture applicable to your debt securities.

The following description summarizes the general terms and provisions of the indentures and the debt securities that Kennametal may offer pursuant to this prospectus that are common to all series, unless otherwise noted or described in a specific prospectus supplement. You should also read the particular terms of an offering of debt securities, which will be described in more detail in the applicable prospectus supplement. This summary is not complete and is subject to, and qualified in its entirety by, reference to the terms and provisions of the indenture. If this summary refers to particular provisions in the indenture, such provisions, including the definition of terms, are incorporated by reference in this prospectus as part of this summary. Kennametal urges you to read the indentures and any supplements thereto because these documents, and not this section, define your rights as a holder of debt securities. Because the terms of specific series of debt securities offered may differ from the general information that Kennametal has provided below, you should rely on information in the applicable prospectus supplement that supersedes or contradicts any information below.

In this section, "Kennametal" refers to Kennametal Inc., excluding its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

**General** 

The debt securities will be Kennametal's direct unsecured obligations. The senior debt securities will rank equally with all of Kennametal's other senior unsecured and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment to all of Kennametal's present and future senior indebtedness to the extent and in the manner set forth in the Subordinated Indenture. The debt securities will not be secured by any of the property or assets or Kennametal or any of its subsidiaries. Thus, by owning a debt security, you are one of Kennametal's unsecured creditors.

Kennametal conducts certain of its operations through its subsidiaries and expects that it will continue to do so. As a result, the cash flow and the consequent ability to service our indebtedness, including the debt securities, is partially dependent upon the earnings of our subsidiaries and the distribution of those earnings or upon the payments of funds by those subsidiaries to Kennametal. Kennametal's subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the debt securities or to make funds available to it, whether by dividends, loans or other payments. Paying dividends and making loans

##### [**Table of Contents**](#toc)
and advances to Kennametal by its subsidiaries may be subject to contractual or statutory restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations. Any right Kennametal may have to receive assets of any of its subsidiaries upon their liquidation or reorganization (and the consequent right of the holders of our debt securities to participate in those assets) will be effectively subordinated to the claims of such subsidiary's creditors, including trade creditors.

The indentures do not limit the aggregate principal amount of debt securities that Kennametal may issue and provide that Kennametal may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. Kennametal may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable indenture. The indentures also do not limit Kennametal's ability to incur other debt.

You should refer to the prospectus supplement relating to the particular series of debt securities for a description of the following terms of the debt securities offered thereby and by this prospectus:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title of the debt securities of the series and whether they are senior debt or subordinated debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate principal amount of the debt securities of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether any debt securities of the series are to be issuable in permanent global form with or without coupons;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date or dates on which the principal of the debt securities of the series is payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the price or prices at which the debt securities are being offered or the method of determining the prices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the rate or rates at which the debt securities of the series will bear interest (including reset rates, if any,
and the method by which such rates will be determined) and, if applicable to such series of debt securities, the basis points and United States Treasury rate(s) and any other rates or other methods to be used in calculating the reset rate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the basis upon which interest will be calculated if other than on the basis of a 360-day year of twelve 30-day months;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date or dates from which such interest will accrue;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the interest payment dates on which such interest will be payable and the regular record date for the interest

any such option);

Indenture).

Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange and will be issued in fully-registered form without coupons.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies, currency units or composite currencies, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

**Subordination** 

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions, including the extent of subordination of payments by us of the principal of, premium, if any, and interest on such subordinated debt securities.

The Subordinated Indenture does not limit the issuance of additional senior indebtedness.

##### [**Table of Contents**](#toc)
**Certain Covenants** 

Except as set forth below or in any indenture supplemental to the indentures or in a board resolution establishing a series of securities under the indentures, the indentures will not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the amount of indebtedness or lease obligations that may be incurred by us and our subsidiaries; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contain provisions which would give holders of the debt securities the right to require us to repurchase their
debt securities in the event of a decline in the credit rating of our debt securities resulting from a change in control, recapitalization or similar restructuring or in the case of any other event.

**Consolidation, Merger and Sale of Assets** 

Kennametal may not consolidate, or merge with or into any other corporation, sell, assign, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any person in one transaction or a series of related transactions, unless among other things, (a) either Kennametal is the surviving person or the person formed by or resulting from any such consolidation or merger or the transferee of such properties and assets shall be a corporation, partnership or trust or other entity organized and existing under the laws of the United States, any state thereof or the District of Columbia and shall expressly assume by supplemental indenture, all of the obligations of Kennametal under the debt securities and the indenture and (b) immediately before and after giving effect to such transaction or series of related transactions, no event of default shall have occurred and be continuing.

**Events of Default** 

The following events are defined in the indentures as "Events of Default":

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of interest or any sinking fund payment on any debt securities of a series when due and
payable and the default continues for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of principal of (or premium, if any, on), any debt securities of a series when due and
payable at maturity, upon acceleration or redemption, by declaration or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to observe or perform in any material respect any of Kennametal's other covenants, warrants or
agreements in any debt securities of a series or the indenture, and the failure to observe or perform continues for 90 days after notice by the trustee or the holders of 25% in aggregate principal amount of the outstanding debt securities of the
series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment at maturity or resulting from acceleration from a payment default of any indebtedness of
Kennametal of $50 million or more under any other indenture, mortgage or instrument that is not cured or waived within 30 days after written notice to Kennametal sent by either the trustee or holders of 25% aggregate principal amount of the
debt securities of the series outstanding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain events of bankruptcy, insolvency or reorganization; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other Event of Default provided with respect to any debt securities of a series in any supplemental
indenture.

If an Event of Default shall occur and be continuing with respect to a series of debt securities, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of such series (or such lesser amount as may be provided for in the debt securities of such series) may declare the unpaid principal of and any accrued interest to the date of acceleration on all the outstanding debt securities of such series to be due and payable immediately; provided that, in the case of an Event of Default involving certain events of bankruptcy, insolvency or reorganization, such acceleration is automatic. After such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, subject to certain conditions, rescind an acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of the principal and interest of the

------

##### [**Table of Contents**](#toc)
securities of that series that has become due solely by such declaration of acceleration, have been cured or waived, (ii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal that has become due otherwise than by such declaration of acceleration have been paid, (iii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (iv) all payments due to the trustee and any predecessor trustee as required under the indenture have been made. Upon the acceleration of the maturity of original issue discount securities, an amount less than the principal amount thereof may become due and payable. Reference is made to the prospectus supplement relating to any original issue discount securities for the particular provisions relating to acceleration of maturity thereof.

The indentures provide that the trustee shall, after the occurrence of an Event of Default with respect to a particular series of debt securities, give notice of such default known to it to the holders of the debt securities within 30 days of its occurrence unless the Event of Default has been cured or waived; provided that the trustee may withhold such notice if such event of default is not a default in the payment of principal of (or premium, if any) or interest, and the Board, the executive committee or directors or the trustee in good faith determine that the withholding of such notice is in the interest of the holders of such securities of the series.

Kennametal will be required to deliver to the trustee a notice of default within 10 days of the occurrence of any default and an officer's certificate setting forth the details of the default and the actions Kennametal proposes to take to cure such default.

No holder of any debt securities of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to the indentures, or for the appointment of a receiver or trustee, or for any other remedy under the indentures unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such holder has previously given the trustee written notice of a continuing Event of Default;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holders of not less than 25% of the outstanding principal amount of the debt securities of a series shall
have made written request to the trustee for such series to institute proceedings in respect of such Event of Default;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the trustee shall have been offered reasonable indemnity against its costs, expenses and liabilities to be
incurred in compliance with such request;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the trustee shall have failed to institute proceedings 60 days after the receipt of such notice, request and
offer of indemnity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• no direction inconsistent with such written request has been given to the trustee during the 60-day period by the holders of a majority in principal amount of the outstanding debt securities of such series.

However, a holder may bring a lawsuit to receive payment of the principal of (and premium, if any) and interest on such debt securities on the stated maturity date of any debt security.

The holders of a majority in principal amount of a particular series of debt securities outstanding will have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee with respect to such series or exercising any trust or power conferred to the trustee; provided that such direction will not conflict with law or with the indenture, the trustee may take any other action deemed proper by it which is not inconsistent with such direction, and the trustee need not take any action which might involve the trustee in personal liability or be unduly prejudice to the holders not joining therein. The indentures provide that in case an Event of Default shall occur and be continuing and known to the trustee, the trustee shall exercise such of its rights and powers under the indentures and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indentures at the request of any of the holders of debt securities of a particular series unless they shall have offered to the trustee security or indemnity reasonably satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request.

##### [**Table of Contents**](#toc)
**Discharge, Defeasance and Covenant Defeasance** 

Unless otherwise indicated to the contrary in the applicable prospectus supplement, Kennametal may discharge or defease its obligations under each indenture as set forth below.

Unless otherwise indicated in the applicable prospectus supplement, Kennametal may elect either (1) to defease and be discharged from any and all obligations with respect to the debt securities of or within any series (except for, among other things, the obligation to pay additional amounts, if any, upon the occurrence of certain events of taxation, assessment or governmental charge with respect to payments on debt securities of such series and other obligations to register the transfer or exchange of debt securities of such series, to replace temporary or mutilated, destroyed, lost or stolen debt securities, to maintain an office or agency with respect to the debt securities and to hold moneys for payment in trust), or (2) to be released from its obligations with respect to certain covenants applicable to the debt securities of or within any series of debt securities and any omission to comply with such obligations shall not constitute an Event of Default with respect to such series of debt securities upon the deposit with the indenture trustee, in trust for such purpose, of money and/or government obligations which through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of (and premium, if any) or interest on such debt securities to maturity. As a condition to defeasance or covenant defeasance, Kennametal must, among other things, deliver to the trustee an opinion of counsel to the effect that the holders of such debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (1) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable federal income tax law occurring after the date of the relevant indenture. In addition, in the case of either defeasance or covenant defeasance, Kennametal must deliver to the trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

We may exercise our defeasance option with respect to such debt securities notwithstanding our prior exercise of our covenant defeasance option.

**Modification and Waiver** 

Modification and amendments of the indentures may be made by Kennametal and the trustee with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of each series affected thereby; provided, however, that no such modification or amendment may, without the consent of the holder of each outstanding debt security affected thereby:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity of the principal of, or any installment of principal of or interest on, any debt
securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount of, or the rate of interest thereon or any premium payable upon the redemption of,
debt securities of any series or extend the time for payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the amount of the principal of an original issue discount debt security that would be due and payable upon
a declaration of acceleration of the maturity thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the place of payment where, or the coin or currency in which, the principal of, or any premium or interest
on, any debt security of any series is payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impair the right to institute suit for the enforcement of any such payment on or after the stated maturity of
debt securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage in principal amount of the outstanding of debt securities of any series, the consent of
whose holders is required for any supplemental indenture or consent required for any waiver of compliance;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the redemption provisions in a manner adverse to such holder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modify any of the above provisions.

The holders of at least a majority in aggregate principal amount of the debt securities of any series may, on behalf of the holders of all debt securities of such series, waive compliance with certain restrictive provisions of the applicable indenture. The holders of not less than a majority in aggregate principal amount of the outstanding debt securities of any series may, on behalf of the holders of all debt securities of such series, waive any past default and its consequences under the indenture with respect to the debt securities of such series, except a default:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in respect of the payment of principal of (or premium, if any), or interest on debt securities of such series; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of
the holder of each outstanding debt security of such series affected.

Notwithstanding the foregoing, without notice to or the consent of any holders of a series of the debt securities, Kennametal may enter into a supplemental indenture to evidence the succession of another corporation to the company and the assumption by any such successor of the covenants of the company in the indentures, to add covenants for the benefit of the holders, to add additional events of default, to secure the debt securities, to evidence the appointment of a successor trustee, to cure any ambiguity, defect or inconsistency or to correct or supplement any provision which may be inconsistent, to make any change that does not materially adversely affect the interests of the holders of the debt securities of such series.

The Subordinated Indenture may not be amended to alter the subordination of any outstanding subordinated debt securities without the consent of each holder of then outstanding senior indebtedness that would be adversely affected by such amendment.

**Payment and Paying Agents** 

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any interest payment date will be made to the person in whose name a debt security is registered at the close of business on the record date for such interest.

Unless otherwise indicated in the applicable prospectus supplement, principal, interest and premium on the debt securities of a particular series will be payable at the office of such paying agent or paying agents as Kennametal may designate for such purpose from time to time. Notwithstanding the foregoing, at Kennametal's option, payment of any interest may be made by check mailed to the address of the person entitled thereto as such address appears in the security register.

Unless otherwise indicated in the applicable prospectus supplement, Kennametal will designate a paying agent to act as paying agent for payments with respect to debt securities of each series. All paying agents initially designated by Kennametal for the debt securities of a particular series will be named in the applicable prospectus supplement. Kennametal may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that Kennametal will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

All moneys paid by Kennametal to a paying agent for the payment of the principal, interest or premium on any debt security that remain unclaimed at the end of two years after such principal, interest or premium has become due and payable will be repaid to Kennametal upon request, and the holder of such debt security shall thereafter, as an unsecured general creditor, look only to Kennametal for payment thereof.

------

##### [**Table of Contents**](#toc)
**Denominations, Registrations and Transfer** 

Unless an otherwise indicated in the applicable prospectus supplement, debt securities of any series may be issued under a book-entry system in the form of one or more global securities. Each global security will be deposited with, or on behalf of, a depositary, which will be The Depository Trust Company, New York, New York ("DTC"). Global securities will be registered in the name of the Depositary or its nominee.

DTC has advised Kennametal that it is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of the New York banking law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC's participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations, some of which (and/or their representatives) own DTC. Access to DTC's book-entry system is also available to others, such as banks, brokers, dealers, and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a global security may not be transferred except as a whole by DTC for such global security to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor of DTC or a nominee of that successor.

The specific terms of DTC arrangement with respect to any debt securities of a series will be described in the relevant prospectus supplement. Kennametal anticipates that the following provisions will apply to all DTC arrangements.

Upon the issuance of a global security, DTC will credit on its book-entry registration and transfer system the respective principal amounts of the debt securities represented by that global security to the participants' accounts. The accounts to be credited will be designated by the underwriters or agents with respect to the debt securities or by Kennametal if the debt securities are offered and sold directly by it. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants. Ownership of a participant's interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC for that global security. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by participants or persons that hold interests through participants. The laws of some jurisdictions require that some purchasers of securities take physical delivery of those securities in definitive form. These limits and laws may impair the ability to transfer beneficial interests in a global security.

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture. Except as set forth below, owners of beneficial interests in a global security will not be entitled to have debt securities of the series represented by a global security registered in their names, will not receive or be entitled to receive physical delivery of debt securities of that series in definitive form and will not be considered the owners or holders thereof under the indenture.

Principal, premium, if any, on and any interest payments on debt securities registered in the name of DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner of a global security representing the debt securities. None of Kennametal, the trustee, any paying agent or the security registrar for any debt securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global security or securities for the debt securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

------

##### [**Table of Contents**](#toc)
Kennametal expects that DTC, upon receipt of any payment of principal, premium or interest, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security or securities for the debt securities as shown on the records of DTC. Kennametal also expects that payments by participants to owners of beneficial interests in a global security or securities held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such participants.

A holder of debt securities may only exchange a beneficial interest in a global security for certificated securities registered in the holder's name if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• DTC notifies Kennametal that it is unwilling or unable to continue serving as the depositary for the relevant
global securities or DTC ceases to maintain certain qualifications under the Exchange Act and no successor depositary has been appointed for 90 days; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Kennametal determines, in its sole discretion (but subject to the procedures of DTC), that the global security
shall be exchangeable.

Further, if Kennametal so specifies with respect to the debt securities of a series, an owner of a beneficial interest in a global security may, on terms acceptable to Kennametal, receive debt securities in definitive form. In that instance, an owner of a beneficial interest in a global security will be entitled to have debt securities of the series represented by that global security equal in principal amount to such beneficial interest registered in its name and will be entitled to physical delivery of those debt securities in definitive form.

**Governing Law** 

The indentures and debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York, without regard to its principles of conflicts of laws, except to the extent that the Trust Indenture Act is applicable, in which case the Trust Indenture Act will govern.

**Concerning the Trustee** 

U.S. Bank National Association is the trustee under the Senior Indenture and Kennametal anticipates appointing U.S. Bank National Association as the trustee under the Subordinated Indenture and also as the paying agent, conversion agent, registrar and custodian with regard to the debt securities. The trustee or its affiliates may in the future provide banking and other services to us in the ordinary course of their respective businesses.

**Conversion or Exchange Rights** 

The applicable prospectus supplement will describe the terms, if any, on which a series of debt securities may be convertible into or exchangeable for Kennametal common stock, preferred stock or other debt securities. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. These provisions may allow or require the number of shares of Kennametal common stock or other securities to be received by the holders of such series of debt securities to be adjusted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the warrants will be issued in fully registered form or bearer form, in definitive or global form or in
any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents,

Alternatively, the purchase contracts may obligate us to purchase from holders, and obligate holders to sell to us, a specific or variable number of our debt securities, shares of common stock, warrants, rights or other property, or any combination of the above. The price of the securities or other property subject to the purchase contracts may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula described in the purchase contracts. We may issue purchase contracts separately or as a part of units each consisting of a purchase contract and one or more of our other securities described in this prospectus or securities of third parties, including U.S. Treasury securities, securing the holder's obligations under the purchase contract. The purchase contracts may require us to make periodic payments to holders or vice versa and the payments may be unsecured or pre-funded on some basis. The purchase contracts may require holders to secure the holder's obligations in a manner specified in the applicable prospectus supplement.

The applicable prospectus supplement will describe the terms of any purchase contracts in respect of which this prospectus is being delivered, including, to the extent applicable, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the purchase contracts obligate the holder or us to purchase or sell, or both purchase and sell, the
securities subject to purchase under the purchase contract, and the nature and amount of each of those securities, or the method of determining those amounts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the purchase contracts are to be prepaid;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the purchase contracts are to be settled by delivery, or by reference or linkage to the value,
performance or level of the securities subject to purchase under the purchase contract;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any acceleration, cancellation, termination or other provisions relating to the settlement of the purchase
contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any applicable U.S. federal income tax considerations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the purchase contracts will be issued in fully registered or global form.

**DESCRIPTION OF UNITS** 

We may issue units consisting of common stock, preferred stock, one or more debt securities, warrants, rights or purchase contacts for the purchase of common stock, preferred stock and/or debt securities in one or more series, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each security included in the unit. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation and terms of the units and of the securities comprising the units, including whether and under
what circumstances those securities may be held or transferred separately;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any provisions of the governing unit agreement that differ from those described below; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities
comprising the units.

The provisions described in this section, as well as those set forth in any prospectus supplement or as described under "Description of Capital Stock," "Description of Debt Securities," "Description of Warrants," "Description of Rights" and "Description of Purchase Contracts" will apply to each unit, as applicable, and to any common stock, debt security, warrant, right or purchase contract included in each unit, as applicable.

**DESCRIPTION OF DEPOSITARY SHARES** 

As specified in the applicable prospectus supplement, we may issue fractional interests in shares of Preferred Stock, rather than full shares of Preferred Stock, containing such rights and subject to such terms and conditions as we may specify. If we exercise that option, we will provide for a depositary to issue receipts for depositary shares, each of which will represent a fractional interest in a share of Preferred Stock. The shares of Preferred Stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company depositary that has its principal office in the United States.

**PLAN OF DISTRIBUTION** 

Kennametal may sell our securities in one or more of the following ways (or in any combination) from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to or through underwriters or dealers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• directly to a limited number of purchasers or to a single purchaser; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through agents.

The applicable prospectus supplement will contain the terms of the offering of the securities, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the name or names of any underwriters, dealers or agents and the respective amounts underwritten or purchased by
them;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price of such securities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the proceeds to be received by Kennametal, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any underwriting discounts or agency fees and other items constituting underwriters' or agents'
compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any initial public offering price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any discounts or concessions allowed or reallowed or paid to dealers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any securities exchanges on which the securities may be listed.

Any dealers and agents, in addition to any underwriter, participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and compensation received by them on resale of the securities may be deemed to be underwriting discounts.

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If we use underwriters in the sale of any securities in respect of which this prospectus is being delivered, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at a fixed public offering price or prices or at varying prices determined by the underwriters at the time of
sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at market prices prevailing at the time of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at prices related to prevailing market prices.

Unless otherwise stated in the applicable prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

We may sell the securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from Kennametal at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

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

Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for Kennametal, our subsidiaries and our affiliates in the ordinary course of business.

Each series of securities other than the Common Stock, which is listed on the New York Stock Exchange, will be a new issue of securities and will have no established trading market. We may elect to list any series of securities on an exchange, but, unless otherwise specified in the applicable prospectus supplement, we are not obligated to do so.

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size which creates a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

The place and time of delivery for securities will be set forth in the prospectus supplement for such securities.
