**Item 1.01 Entry into a Material Definitive Agreement**

As previously disclosed, on April 28, 2022, Eos Energy Enterprises, Inc. (the "Company") and YA II PN, LTD ("Yorkville") entered into the Standby Equity Purchase Agreement dated as of April 28, 2022 (as amended, the "SEPA") and a supplemental agreement dated as of December 29, 2022 (the "Second Supplemental Agreement") to the SEPA.

On February 1, 2023, the Company issued and sold a convertible promissory note with an aggregate principal amount of $5.0 million (the "Promissory Note") in a private placement to Yorkville under the Second Supplemental Agreement .

The Company agreed to use the proceeds from the sale of the Promissory Note for working capital and other general corporate purposes or, if different, in a manner consistent with the application thereof described in the Company's prospectus relating to the SEPA filed with the Securities and Exchange Commission on April 28, 2022 and included as a part of the Company's Registration Statement on Form S-3 (File No. 333-263298).

The Promissory Note has a maturity date of June 29, 2023 (the "Maturity Date") and was issued with a 2% original issue discount. Interest shall accrue on the outstanding principal balance of the Promissory Note, beginning on the 29th day following the date of issuance, at an annual rate equal to 5.0% unless and until there is an event of default, upon the occurrence of which, interest shall accrue at a rate of 15% per year until collected in full. The Promissory Note is convertible into shares of the Company's common stock at a conversion price equal to the lower of $1.4883 and 96.5% of the lowest daily volume weighted average price of the Company's common stock during the 7 consecutive trading days immediately preceding the conversion date (the "Conversion Price") any time prior to the Maturity Date, subject to the terms and conditions of the Promissory Note. The Conversion Price may not be less than $0.35 per share (the "Floor Price"). If the volume weighted average price of the Company's common stock is less than the Floor Price for five consecutive trading days, subject to certain limitations, the Company must make weekly payments on the Promissory Note. At any time that there is an outstanding balance owed under the Promissory Note, Yorkville may, pursuant to the terms of the Supplemental Agreement, require the Company to deliver an advance notice under the SEPA for the issuance and sale of common stock at the Conversion Price in order to offset the amounts owed by the Company to Yorkville under the Promissory Note. In addition, while there is an outstanding balance owed under the Promissory Note, Yorkville shall use any advance requested by the Company pursuant to the SEPA to offset the amounts owed by the Company to Yorkville under the Promissory Note.

The foregoing description of the Promissory Note does not purport to be complete and is qualified in its entirety by reference to the full text of the Promissory Note, a copy of which is filed with this Current Report on Form 8-K as Exhibit 4.1 hereto and is hereby incorporated herein by reference. The foregoing description of the Second Supplemental Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Supplemental Agreement, a copy of which is filed as <u>[Ex](https://www.sec.gov/Archives/edgar/data/1805077/000121390022083603/ea170974ex10-2_eosenergy.htm)[hibit 10.2](https://www.sec.gov/Archives/edgar/data/1805077/000121390022083603/ea170974ex10-2_eosenergy.htm)</u> to the Current Report on Form 8-K filed by the Company on December 29, 2022, and is incorporated by reference herein.

**Item 2.02 Results of Operations and Financial Condition**

On February 2, 2023, the "Company" issued a press release updating its revenue outlook for full year 2022, announcing its revenue outlook for full year 2023, and providing certain other business updates. A copy of the press release is furnished herewith as Exhibit 99.1 and is incorporated by reference herein.

The information furnished under this Item 2.02 and in the accompanying Exhibit 99.1 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference in such filing.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information set forth under Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

On February 1, 2023, the Company issued and sold the Promissory Note to Yorkville in a private placement pursuant to the exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). The Company offered and sold the Promissory Note to Yorkville in reliance on the exemption from registration provided by Section 4(a)(2) of

------

the Securities Act without the involvement of any underwriter. The Company relied on this exemption from registration based in part on representations made by Yorkville in the Supplemental Agreement and the SEPA.

**Cautionary Note Regarding Forward-Looking Statements**

This current report includes certain statements that may constitute "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements that refer to our expected revenue for the fiscal year ended December 31, 2022 and cash balance as of December 31, 2022, the Department of Energy Loan approval process, 2023 outlook and projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intends," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Factors which may cause actual results to differ materially from current expectations include, but are not limited to: the preliminary financial information remains subject to changes and finalization based upon management's ongoing review of results for the fourth quarter and full fiscal year 2022 and the completion of all quarter and year end closing procedures; changes adversely affecting the business in which we are engaged; our ability to forecast trends accurately; our ability to secure final approval of a loan from the Department of Energy or the final amount of any loan; our ability to generate cash, service indebtedness and incur additional indebtedness; our ability to secure financing to continue expansion; our ability to develop efficient manufacturing processes to scale and to forecast related costs and efficiencies accurately, and to secure labor; fluctuations in our revenue and operating results; competition from existing or new competitors; the failure to convert firm order backlog and pipeline to revenue; the failure to sufficiently reduce manufacturing costs, potential delays in the launch of our Z3 battery; inefficient implementation of the Inflation Reduction Act of 2022; risks associated with security breaches in our information technology systems; the risk of a government shutdown as Eos remains in due diligence on its loan application with the U.S. Department of Energy Loan Programs Office; risks related to legal proceedings or claims; risks associated with changes in federal, state, or local laws; risks associated with potential costs of regulatory compliance; risks associated with changes to U.S. trade policies; risks resulting from the impact of global pandemics, including the novel coronavirus, Covid-19; and risks related to adverse changes in general economic conditions. The forward-looking statements contained in this current report are also subject to additional risks, uncertainties, and factors, including those more fully described in Eos's most recent filings with the Securities and Exchange Commission, including Eos's most recent Annual Report on Form 10-K and subsequent reports on Forms 10-Q and 8-K. Further information on potential risks that could affect actual results will be included in the subsequent periodic and current reports and other filings that Eos makes with the Securities and Exchange Commission from time to time. Moreover, Eos operates in a very competitive and rapidly changing environment, and new risks and uncertainties may emerge that could have an impact on the forward-looking statements contained in this current report. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and, except as required by law, Eos assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Interest Rate and Payment of Interest</u>. Beginning on the 29<sup>th</sup> day following the Issuance Date, Interest shall accrue on the outstanding Principal balance hereof at an annual rate equal to 5% ("<u>Interest Rate</u>"), which Interest Rate shall increase to an annual rate of 15% upon an Event of Default for so long as it remains uncured. Interest shall be calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Mandatory Payments</u>. If, any time after the Issuance Date, and from time to time thereafter, the daily VWAP is less than the Floor Price for five consecutive Trading Days (the last such day of each such occurrence, a "<u>Triggering Date</u>"), then the Company shall make weekly payments (in accordance with Section 1(d)) beginning on the later of (i) the 10<sup>th</sup> calendar day after the Triggering Date, and (ii) in the event the Triggering Date occurs during or within two Trading Days preceding a Company Black Out Period (as defined in Section 15), the 5<sup>th</sup> calendar day after the cessation of such Company Black Out Period, and continuing on the same day of each successive calendar week. Each weekly payment shall be in an amount equal to the sum of (i) $1,000,000 of Principal (or the outstanding Principal if less than such amount) (the "<u>Triggered Principal Amount</u>"), (ii) the Payment Premium (as defined below, and if applicable in accordance with Section 1(d)) in respect of such Triggered Principal Amount, and (iii) accrued and unpaid interest hereunder as of each payment date (collectively, the "<u>Payment Amount</u>"). The obligation of the Company to make weekly payments hereunder shall cease (with respect to any payment that has not yet come due) if at any time after the Triggering Date the daily VWAP is greater than the Floor Price for a period of five consecutive Trading Days, unless a subsequent Triggering Date occurs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Weekly Payments</u>. With respect to any payment due by the Company pursuant to Section 1(c), the Company shall, at its own option, either (i) repay each Payment Amount by submitting an Advance Notice (an "<u>Advance Repayment</u>") with an Advance Date on or before each applicable due date of such Payment Amount, (ii) repay with the proceeds of sales of Common Shares pursuant to an ATM Agreement, or (iii) repay in cash each Payment Amount on or before the date such Payment Amount is due, provided that, in each case, any such repayment would not violate the terms of the Atlas Facility (as defined in Section 15). In respect of any Payment Amount to be repaid by the Company in accordance with (ii) or (iii) of this Section 1(d), the Company shall pay to the Holder the Payment Amount to be paid to the Holder, which for the avoidance of doubt shall include the Payment Premium, by wire transfer of immediately available funds in cash on or before such due date. If the Company elects an Advance Repayment, then the Company shall deliver an Advance Notice to the Holder in accordance with the terms and conditions of the SEPA requesting an advance amount equal to the Payment Amount, or portion thereof, to be paid by an Advance Repayment, that will have an Advance Date on or before the applicable due date, which Advance Notice shall specify the Payment Amount to be paid pursuant to such Advance Repayment, provided however, the Investor hereby waives the amount of the Payment Premium in respect of any Advance Repayment. Upon the closing of such Advance Notice in accordance with Section 2.02 of the SEPA, the Holder shall offset the amount due to be paid by the Holder to the Company under the SEPA against the portion of the Payment Amount to be paid by the Advance Repayment. If any portion of the Payment Amount remains unpaid at the applicable due date, the Company shall repay such outstanding Payment Amount as a cash repayment pursuant to (ii) or (iii) of this Section 1(d).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Optional Redemption</u>. The Company at its option shall have the right, but not the obligation, to redeem ("<u>Optional Redemption</u>") early a portion or all amounts outstanding under this Note as described in this Section; *provided* that (i) the Company provides the Holder with at least five Trading Days' prior written notice (each, a "<u>Redemption Notice</u>") of its desire to exercise an Optional Redemption, and (ii) the VWAP of the

------

Company's Common Stock on each of the ten Trading Days immediately prior to the Redemption Notice is less than the Fixed Conversion Price, Each Redemption Notice shall be irrevocable and shall specify the outstanding balance of the Note to be redeemed. The "<u>Redemption Amount</u>" shall be equal to the outstanding Principal balance being redeemed by the Company, plus the Payment Premium, plus all accrued and unpaid interest. After receipt of the Redemption Notice, the Holder shall have five Trading Days to elect to convert all or any portion of this Note. On the sixth Trading Day after the Redemption Notice, the Company shall deliver to the Holder the Redemption Amount with respect to the Principal amount redeemed after giving effect to conversions effected during the five Trading Day period. The Holder may convert all or any part of this Note after receiving a Redemption Notice, in which case the Redemption Amount shall be reduced by the amount so converted.

For purposes hereof, "<u>Periodic Reports</u>" means the Company's (i) Annual Report on Form 10-K for the fiscal year ending December 31, 2022, (ii) Current Report on Form 10-Q for the quarterly period ending March 31, 2023, and (iii) all other financial reports required to be filed by the Company with the Commission under applicable laws and regulations (including, without limitation, Regulation S-K) for so long as any amounts are outstanding under this Promissory Note; *provided* that all such Periodic Reports shall include, when filed, all information, financial statements, audit reports (when applicable) and other information required to be included in such Periodic Reports in compliance with all applicable laws and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xi)The Company shall fail to observe or perform any other material covenant, agreement or warranty contained in, or otherwise commit any material breach or default of any provision of this Note (except as may be covered by Section 2(a)(i) through 2(a)(xi) hereof) or any Transaction Document (as defined in Section 15) which is not cured within any cure period prescribed therein.

Furthermore, in addition to any other remedies, the Holder shall have the right (but not the obligation) to convert this Note (subject to the limitations set out in Section 3(c) at any time after (x) an Event of Default or (y) the Maturity Date at the Conversion Price. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, (other than required notice of conversion) and the Holder may immediately enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon. For the purposes hereof, an Event of Default relating to default in payment is "*continuing*" if it has not been waived, and an Event of Default relating to circumstances other than a default in payment is "*continuing*" if it has not been remedied or waived.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)<u>CONVERSION OF NOTE</u>.&nbsp;&nbsp;&nbsp;&nbsp;This Note shall be convertible into shares of the Company's Common Stock, on the terms and conditions set forth in this Section 3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Conversion Right</u>. Subject to the provisions of this Section 3, at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and nonassessable shares of Common Stock, at the Conversion Price. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to this Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price. The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)"<u>Conversion Amount</u>" means the portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)"<u>Conversion Price</u>" means, as of any Conversion Date (as defined below) or other date of determination the lower of (i) $1.4883per share (the "<u>Fixed Conversion Price</u>"), or (ii) 96.5% of the lowest daily VWAP of the Common Stock during the seven (7) consecutive Trading Days immediately preceding the Conversion Date or other date of determination (the "<u>Variable Conversion Price</u>") but not lower than the Floor Price. The Conversion Price shall be adjusted from time to time pursuant to the other terms and conditions of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Mechanics of Conversion</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Optional Conversion</u>. To convert any Conversion Amount into shares of Common Stock on any date (a "<u>Conversion Date</u>"), the Holder shall (A) transmit by email with confirmation of delivery (or otherwise deliver by method set forth in Section 5), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as <u>Exhibit I</u> (the "<u>Conversion Notice</u>") to the Company and (B) if required by Section 3(c)(ii), surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Note in the case of its loss, theft or destruction). On or before the third (3<sup>rd</sup>) Business Day following the date of receipt of a Conversion Notice

------

(the "<u>Share Delivery Date</u>"), the Company shall issue and deliver to the address as specified in the Conversion Notice, a certificate (or book entry), registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. Any shares of Common Stock issued upon conversion shall bear customary restrictive legends regarding restrictions on transfers under the applicable securities laws. If this Note is physically surrendered for conversion and the outstanding balance of this Note is greater than the portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note representing the outstanding balance not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock upon the receipt of a Conversion Notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)<u>Company's Failure to Timely Convert</u>. If within three (3) from the Share Delivery Date the Company shall fail to issue and deliver a certificate to the Holder, issue a book entry in the name of the Holder or credit the Holder's balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon such holder's conversion of any Conversion Amount (a "<u>Conversion Failure</u>"), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company and that is saleable under Rule 144 at the time of such conversion (a "<u>Buy-In</u>"), then the Company shall, within three (3) Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to the Holder's total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Common Stock so purchased (the "<u>Buy-In Price</u>"), at which point the Company's obligation to deliver such certificate or book entry (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates or book entries representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the Conversion Date and such approval is applicable to issuances of shares of Common Stock upon conversion of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)<u>Book-Entry</u>. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Limitations on Conversions</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>Beneficial Ownership</u>. The Holder shall not have the right to convert any portion of this Note to the extent that after giving effect to such conversion, the Holder, together with any affiliate thereof, would beneficially own (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. Since the Holder will not be obligated to report to the Company the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 9.99% of the then outstanding shares of Common Stock without regard to any other shares which may

------

be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority, responsibility and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Principal amount of this Note is convertible shall be the responsibility and obligation of the Holder. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 65 days' prior notice to the Company. Other Holders shall be unaffected by any such waiver.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)<u>Principal Market Limitations</u>. Notwithstanding anything in this Note to the contrary, the Company shall not issue any shares of Common Stock upon conversion of this Note, or otherwise, if the issuance of such Common Stock, together with any Common Stock issued in connection the SEPA and with any other related transactions that may be considered part of the same series of transactions, would exceed the aggregate number of shares of Common Stock that the Company may issue in a transaction in compliance with the Company's obligations under the rules or regulations of Nasdaq Stock Market LLC (the "<u>Nasdaq</u>") and shall be referred to as the "<u>Exchange Cap,</u>" except that such limitation shall not apply if the Company's stockholders have approved such issuances on such terms in excess of the Exchange Cap in accordance with the rules of the Nasdaq.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Other Provisions</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)The Company shall at all times reserve and keep available out of its authorized Common Stock the full number of shares of Common Stock issuable upon conversion of all outstanding amounts under this Note, and within three (3) Business Days following the receipt by the Company of a Holder's notice that such minimum number of Underlying Shares is not so reserved, the Company shall promptly reserve a sufficient number of shares of Common Stock to comply with such requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)All calculations under this Section 3 shall be rounded to the nearest $0.0001 or whole share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section 2 herein for the Company's failure to deliver certificates or issue book entries representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)<u>Conversion Costs</u>. The Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection with any legal opinions paid for by the Holder in connection with sale of Underlying Shares (provided that the Company has first had the opportunity to obtain such a legal opinion on behalf of the Holder). The Holder shall notify the Company of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder shall be paid by the Company with reasonable promptness.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Adjustments to Conversion Price upon Subdivision or Combination of Common Stock</u>. If the Company, at any time while this Note is outstanding, shall (a) pay a stock dividend or otherwise make a distribution or distributions on its Common Stock or any other equity or equity equivalent securities payable in shares which results in an increase in the number of outstanding Common Stock, (b) subdivide its outstanding Common

------

Stock into a larger number, or (c) combine (including by way of reverse share split) outstanding Common Stock into a smaller number, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock outstanding after such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)Whenever the Conversion Price is adjusted pursuant to Section 3 hereof, the Company shall promptly mail to the Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)In case of any (1) merger or consolidation of the Company or any subsidiary of the Company controlling more than one-half of the assets of the Company with or into another Person not affiliated with the Company, or (2) sale by the Company or any subsidiary of the Company of more than one-half of the assets of the Company in one or a series of related transactions, the Holder shall have the right to (A) exercise any rights under Section (3), (B) convert the aggregate amount of this Note then outstanding into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders shares of Common Stock following such merger, consolidation or sale, and such Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as the shares of Common Stock into which such aggregate Principal amount of this Note could have been converted immediately prior to such merger, consolidation or sales would have been entitled, or (C) in the case of a merger or consolidation, require the surviving entity to issue to the Holder a Convertible Note with a Principal amount equal to the aggregate Principal amount of this Note then held by such Holder, plus all accrued and unpaid interest and other amounts owing thereon, which such newly issued Convertible Note shall have terms identical (including with respect to conversion) to the terms of this Note, and shall be entitled to all of the rights and privileges of the Holder of this Note set forth herein and the agreements pursuant to which this Notes were issued. In the case of clause (C), the conversion price applicable for the newly issued Convertible Notes shall be based upon the amount of securities, cash and property that each share of Common stock would receive in such transaction and the Conversion Price in effect immediately prior to the effectiveness or closing date for such transaction. The terms of any such merger, sale or consolidation shall include such terms so as to continue to give the Holder the right to receive the securities, cash and property set forth in this Section upon any conversion or redemption following such event. This provision shall similarly apply to successive such events.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)<u>REISSUANCE OF THIS NOTE</u>.

The Holder and any assignee, by acceptance of this Note benture, acknowledge and agree that, by reason of the provisions of Section 3(c)(ii) following conversion, repayment, or redemption of any portion of this Note, the outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note.

**Eos Energy Enterprises, Inc. Provides Business Update**

*Company Announces New Project Order, Incremental Issuance under the SEPA, Expected 2022 Revenue Results, and Initiates 2023 Revenue Outlook* 

EDISON, N.J.— Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos"), a leading provider of safe, scalable, efficient, and sustainable zinc-based energy storage systems, today announced that it expects to record revenue of $17 to $20 million for 2022, which is consistent with previous guidance, with an ending cash balance (excluding restricted cash) of $17 million as of December 31, 2022. Eos will provide further commentary on its fourth quarter performance in connection with the release of its full year and fourth quarter 2022 financial results in early March.

Eos also announces an order for a 47 MWh initial renewables plus storage project with one of the largest operators of energy storage in the US, along with a separate long term agreement providing a framework for up to 4 GWh of energy storage volume over the next 6 years (the "Agreement"). The Agreement contributes 4GWh to the Company's Pipeline and will be categorized as a letter of intent. With its active Pipeline, as well as the expected launch of the automated next generation Z3 battery production line in the third quarter, the Company currently expects 2023 revenue to be in the range of $30 to $50 million. The gross margins of Z3 are expected to be better than the current Gen 2.3 product, which we believe should result in positive operating cashflow in the second half of 2024. On February 1, 2023, the Company also issued and sold a convertible promissory note with an aggregate principal amount of $5.0 million in a private placement to YA II PN, LTD, an affiliate of Yorkville Advisors, under the Second Supplemental Agreement dated as of December 29, 2022, to the SEPA between the Company and Yorkville.

"We are very excited about our continued growth and the Agreement," said Joe Mastrangelo, CEO of Eos. "With implementation of the 2022 Inflation Reduction Act taking place this year, we foresee continued market expansion. We continue to progress through the Department of Energy Loan Programs Office's due diligence process, and we expect that our loan amount could be at least $250 million, if successfully approved."

Eos is providing this preliminary select results and 2023 outlook in advance of upcoming investor meetings prior to release of earnings.

**About Eos**

Eos Energy Enterprises, Inc. is accelerating the shift to clean energy with positively ingenious solutions that transform how the world stores power. Our breakthrough Znyth<sup>™</sup> aqueous zinc battery was designed to overcome the limitations of conventional lithium-ion technology. Safe, scalable, efficient, sustainable—

![image3.jpg](image3.jpg)

------

and manufactured in the U.S.—it's the core of our innovative systems that today provide utility, industrial, commercial, and residential customers with a proven, reliable energy storage alternative. Eos was founded in 2008 and is headquartered in Edison, New Jersey. For more information about Eos (NASDAQ: EOSE), visit eose.com.

**Key Metrics** 

**Backlog**. The Company defines backlog as the amount of revenue that we expect to realize from existing agreements with our customers for the sale of our battery energy storage systems and performance of services. The backlog is calculated by adding new orders in the current fiscal period to the backlog as of the end of the prior fiscal period and then subtracting the shipments in the current fiscal period. If the amount of an order is modified or cancelled, we adjust orders in the current period and our backlog accordingly, but do not retroactively adjust previously published backlogs. We believe that the backlog is a useful indicator regarding the future revenue of our Company.

**Pipeline**. Our pipeline represents projects for which we have submitted technical proposals or nonbinding quotes plus letters of intent ("LOI") or firm commitments from customers. Pipeline does not include lead generation projects.

**Booked Orders**. Booked orders are orders where we have legally binding agreements with a Purchase Order or Master Supply Agreement executed by both parties.

**Forward-Looking Statements**

This press release includes certain statements that may constitute "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements that refer to our expected revenue for the fiscal year ended December 31, 2022 and cash balance as of December 31, 2022, the Department of Energy Loan approval process, 2023 outlook and projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intends," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Factors which may cause actual results to differ materially from current expectations include, but are not limited to: the preliminary financial information remains subject to changes and finalization based upon management's ongoing review of results for the fourth quarter and full fiscal year 2022 and the completion of all quarter and year end closing procedures; changes adversely affecting the business in which we are engaged; our ability to forecast trends accurately; our ability to secure final approval of a loan from the Department of Energy or the final amount of any loan; our ability to generate cash, service indebtedness and incur additional indebtedness; our ability to secure financing to continue expansion; our ability to develop efficient manufacturing processes to scale and to forecast related costs and efficiencies accurately, and to secure labor; fluctuations in our revenue and operating results; competition from existing or new competitors; the failure to convert firm order backlog and pipeline to revenue; the failure to sufficiently reduce manufacturing costs, potential delays in the launch of our Z3 battery; inefficient implementation of the Inflation Reduction Act of 2022; risks associated with security breaches in our information technology systems; the risk of a government shutdown as Eos remains in due diligence on its loan application with the U.S. Department of Energy Loan Programs Office; risks related to legal proceedings or claims; risks associated with changes in federal, state, or local laws; risks associated with potential costs of regulatory compliance; risks associated with changes to U.S. trade policies; risks resulting from the impact of global pandemics, including the novel coronavirus, Covid-19; and risks related to adverse changes in general economic conditions. The forward-looking statements contained in this press release are also subject to additional risks, uncertainties, and factors, including those more fully described in Eos's most recent filings with the Securities and Exchange Commission, including Eos's most recent Annual Report on Form 10-K and subsequent reports on Forms 10-Q and 8-K.

Moreover, Eos operates in a very competitive and rapidly changing environment, and new risks and uncertainties may emerge that could have an impact on the forward-looking statements contained in this press release. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and, except as required by law, Eos assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.
