Item 1.01
Entry into a Material Definitive Agreement.

On August 13, 2024, bluebird bio, Inc. (the “Company”) entered into an amendment (the “Third Amendment”) to its Loan and Security Agreement, dated as of March 15, 2024, as amended on April 30, 2024 and July 9, 2024 (the “LSA”), by and among the Company, the several banks and other financial institutions or entities party thereto, as lenders (collectively, the “Lenders”), and Hercules Capital, Inc., as administrative agent and collateral agent (the “Agent”).

The LSA provides a secured term loan facility of up to $175.0 million (the “Term Loans”), consisting of four tranches, the first of which was funded at closing on March 15, 2024 in an aggregate amount of $75.0 million. Pursuant to the Third Amendment, the Company, the Agent and the Lenders agreed to, among other things: (a) revised terms for the availability of the second tranche of $25.0 million, which the Company may draw subject to customary terms and conditions, during the period commencing on the date the Company has (x) received at least $75.0 million in gross cash proceeds from qualified financing transactions by December 20, 2024 and (y) completed patient starts (cell collections) for at least 50 LYFGENIA patients by March 31, 2025 or 70 LYFGENIA patients by June 30, 2025 (collectively, the “Tranche 2 Milestone”) and ending on the earlier of (i) the date that is 30 days immediately following achievement of the Tranche 2 Milestone and (ii) July 31, 2025; and (b) revised terms for the availability of the third tranche of $25.0 million, which the Company may draw, subject to customary terms and conditions, during the period commencing on the date the Company has (x) received at least $100.0 million in gross cash proceeds from qualified financing transactions by December 20, 2024 or at least $125.0 million by June 30, 2025 and (y) completed 70 drug product deliveries within a given six-month period ending no later than December 31, 2025, at least 40 of which are for LYFGENIA (collectively, the “Tranche 3 Milestone”) and ending on the earlier of (i) the date that is 30 days immediately following the date the Company achieves the Tranche 3 Milestone and (ii) December 31, 2025. The fourth tranche of $50.0 million remains available in the sole discretion of the Lenders, and subject to customary terms and conditions, until December 15, 2026.

Additionally, the Third Amendment provides that the Terms Loans will be repayable in monthly interest-only payments until April 1, 2027, or April 1, 2028, if the Company has achieved, no later than December 31, 2026, the Tranche 3 Milestone and has generated at least $10.0 million of EBITDA on a trailing six-month basis (the “Performance Milestone”). Pursuant to the Third Amendment, the Company will pay an end of term charge of 6.45% upon the prepayment or repayment of the Term Loans.

Further, pursuant to the Third Amendment, the parties agreed to the following revisions to the financial covenants: (a) the Company is required to maintain, at all times, “Qualified Cash” (defined as cash in accounts subject to control agreements minus any accounts payable not paid after the 120th day) in an amount greater than or equal to the outstanding principal amount of the Term Loans, multiplied by 45%; provided that if the Tranche 3 Milestone has occurred, the foregoing percentage will be decreased to 35% and if the Performance Milestone has occurred, the foregoing percentage will be reduced to 20%; and (b) commencing with the fiscal quarter ending December 31, 2024, the Company is required to maintain quarterly trailing six-month net product revenue from the sale of LYFGENIA, ZYNTEGLO and SKYSONA in designated amounts as set forth in the Third Amendment.

In connection with entry into the Third Amendment, the Company also agreed to amend the exercise price of warrants (the “Warrants”) to purchase shares of the Company’s common stock from $1.45 per share to the lesser of (a) the volume weighted average price of the Company’s common stock for the ten-day period preceding August 13, 2024, and (b) the price per share of the Company’s first equity financing event within six months of August 13, 2024. The amendment does not impact the number of shares the Lenders may purchase pursuant to the Warrants.

    The foregoing description of the Third Amendment and the Warrants does not purport to be complete and is qualified in its entirety by the full text of the Third Amendment, the Form of Warrant Agreement, and the Form of Warrant Agreement Amendment, copies of which are filed as Exhibit 10.1, Exhibit 4.1 and Exhibit 4.2 to this Current Report on Form 8-K, respectively, and incorporated herein by reference.

BLUEBIRD BIO, INC.

Dated as of March 15, 2024 (the “Effective Date”)

    WHEREAS, bluebird bio, Inc., a Delaware corporation (the “Company”), has entered into a Loan and Security Agreement of even date herewith (as amended and in effect from time to time, the “Loan Agreement”) with Hercules Capital, Inc., a Maryland corporation, in its capacity as administrative and collateral agent, [__________], a [__________], (the “Warrantholder”), and the other parties thereto;

    WHEREAS, pursuant to the Loan Agreement and as additional consideration to the Warrantholder for, among other things, its agreements in the Loan Agreement, the Company has agreed to issue to the Warrantholder this Warrant Agreement, evidencing the right to purchase shares of the Company’s Common Stock (this “Warrant”, “Warrant Agreement”, or “Agreement”, and together with any additional Warrants issued upon any permitted transfer of this Warrant hereunder, collectively, the “Warrants”);
    NOW, THEREFORE, in consideration of the Warrantholder having executed and delivered the Loan Agreement and provided the financial accommodations contemplated therein, and in consideration of the mutual covenants and agreements contained herein, the Company and the Warrantholder agree as follows:
SECTION 1.GRANT OF THE RIGHT TO PURCHASE COMMON STOCK.

The number and Exercise Price of such shares are subject to adjustment as provided in Section 8. As used herein, the following terms shall have the following meanings:

Charter” means the Company’s Amended and Restated Certificate of Incorporation, as amended, or other constitutional document, as may be amended and in effect from time to time.

(b)    Number of Shares. This Warrant shall be exercisable for a number of shares of Common Stock equal to the quotient of (i) the Warrant Coverage, divided by (ii) the Exercise Price, subject to adjustment from time to time in accordance with the provisions of this Warrant.

2



SECTION 2.TERM OF THE AGREEMENT.
    The term of this Agreement and the right to purchase Common Stock as granted herein shall commence on the Effective Date and, subject to Section 8(a) below, shall be exercisable until 5:00 p.m. (Eastern Time) on the seventh (7th) anniversary of the Effective Date.
SECTION 3.EXERCISE OF THE PURCHASE RIGHTS.
(a)    Exercise. The purchase rights set forth in this Agreement are exercisable by the Warrantholder, in whole or in part, at any time, or from time to time, prior to the expiration of the term set forth in Section 2, by tendering to the Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly completed and executed. Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in accordance with the terms set forth below, and in no event later than three (3) business days thereafter, the Company or its transfer agent shall either (i) issue to the Warrantholder a certificate for the number of shares of Common Stock purchased or (ii) credit the same via book entry to the Warrantholder, and the Company shall execute the acknowledgment of exercise in the form attached hereto as Exhibit II (the “Acknowledgment of Exercise”) indicating the number of shares which remain subject to future purchases under this Warrant, if any.

    The Purchase Price may be paid at the Warrantholder’s election either (i) by cash or check, or (ii) by surrender of all or a portion of the Warrant for shares of Common Stock to be exercised under this Agreement and, if applicable, an amended Agreement setting forth the remaining number of shares purchasable hereunder, as determined below (“Net Issuance”). If the Warrantholder elects the Net Issuance method, the Company will issue shares of Common Stock in accordance with the following formula:

X = Y(A-B)
             A

Where:    X =     the number of shares of Common Stock to be issued to the Warrantholder.
    Y =     the number of shares of Common Stock requested to be exercised under this Agreement.
    A =     the then-current fair market value of one (1) share of Common Stock at the time of exercise of this Warrant.
        B =     the then-effective Exercise Price.
For purposes of the above calculation, the current fair market value of shares of Common Stock shall mean with respect to each share of Common Stock:

    (i)     at all times when the Common Stock is traded on a national securities exchange, inter-dealer quotation system or over-the-counter bulletin board service, the volume weighted average price over a ten (10) day period ending the day before the current fair market value of the securities is being determined;

    (ii)    if the exercise is in connection with a Merger Event, the fair market value of a share of Common Stock shall be deemed to be the per share value received by the holders of the outstanding shares of Common Stock pursuant to such Merger Event as determined in accordance with the definitive transaction documents executed among the parties in connection therewith; or

    (iii)    in cases other than as described in the foregoing clauses (i) and (ii), the current fair market value of a share of Common Stock shall be determined in good faith by the Company’s Board of Directors.

    Upon partial exercise by either cash or Net Issuance, prior to the expiration or earlier termination hereof, the Company shall promptly issue an amended Agreement
3



representing the remaining number of shares purchasable hereunder. All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not limited to the Effective Date hereof.

(b)    Exercise Prior to Expiration. To the extent this Warrant is not previously exercised as to all shares of Common Stock subject hereto, and if the then-current fair market value of one share of Common Stock is greater than the Exercise Price then in effect, or, in the case of a Liquid Sale, where the value per share of Common Stock (as determined as of the closing of such Liquid Sale in accordance with the definitive agreements executed by the parties in connection with such Merger Event) to be paid to the holders thereof is greater than the Exercise Price then in effect, this Agreement shall be deemed automatically exercised on a Net Issuance basis pursuant to Section 3(a) (even if not surrendered) as of immediately before its expiration determined in accordance with Section 2. For purposes of such automatic exercise, the fair market value of one share of Common Stock upon such expiration shall be determined pursuant to Section 3(a). To the extent this Warrant or any portion hereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to promptly notify the Warrantholder of the number of shares of Common Stock if any, the Warrantholder is to receive by reason of such automatic exercise, and to issue or cause its transfer agent to issue a certificate or a book-entry credit to the Warrantholder evidencing such shares.

SECTION 4.RESERVATION OF SHARES.
    During the term of this Agreement, the Company will at all times have authorized and reserved a sufficient number of shares of its Common Stock to provide for the exercise of the rights to purchase Common Stock as provided for herein. If at any time during the term hereof the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant in full, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.
SECTION 5.NO FRACTIONAL SHARES OR SCRIP.
    No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Agreement, but in lieu of such fractional shares the Company shall make a cash payment therefor in an amount equal to the product of (a) the Exercise Price then in effect multiplied by (b) the fraction of a share.
SECTION 6.NO RIGHTS AS SHAREHOLDER.
    Without limitation of any provision hereof, the Warrantholder agrees that this Agreement does not entitle the Warrantholder to any voting rights or other rights as a shareholder of the Company prior to the exercise of any of the purchase rights set forth in this Agreement.
SECTION 7.WARRANTHOLDER REGISTRY.
    The Company shall maintain a registry showing the name and address of the registered holder of this Agreement. The Warrantholder’s initial address, for purposes of such registry, is set forth in Section 12(g) below. The Warrantholder may change such address by giving written notice of such changed address to the Company.
SECTION 8.ADJUSTMENT RIGHTS.
    The Exercise Price and the number of shares of Common Stock purchasable hereunder are subject to adjustment from time to time, as follows:
(a)Merger Event. In connection with a Merger Event that is a Liquid Sale, this Warrant shall, on and after the closing thereof, automatically and without further action on the part of any party or other person, represent the right to receive the consideration payable on or in respect of all shares of Common Stock that are issuable hereunder as of immediately prior to the closing of such Merger Event less the Purchase Price for all such shares of Common Stock
4



(such consideration to include both the consideration payable at the closing of such Merger Event and all deferred consideration payable thereafter, if any, including, but not limited to, payments of amounts deposited at such closing into escrow and payments in the nature of earn-outs, milestone payments or other performance-based payments), and such Merger Event consideration shall be paid to the Warrantholder as and when it is paid to the holders of the outstanding shares of Common Stock. In connection with a Merger Event that is not a Liquid Sale, the Company shall cause the successor or surviving entity to assume this Warrant and the obligations of the Company hereunder on the closing thereof, and thereafter this Warrant shall be exercisable for the same number and type of securities or other property as the Warrantholder would have received in consideration for the shares of Common Stock issuable hereunder had it exercised this Warrant in full as of immediately prior to such closing, at an aggregate Exercise Price no greater than the aggregate Exercise Price in effect as of immediately prior to such closing, and subject to further adjustment from time to time in accordance with the provisions of this Warrant. The provisions of this Section 8(a) shall similarly apply to successive Merger Events.
(b)Reclassification of Shares. Except for Merger Events subject to Section 8(a), if the Company at any time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities as to which purchase rights under this Agreement exist into the same or a different number of securities of any other class or classes of securities, this Agreement shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change. The provisions of this Section 8(b) shall similarly apply to successive combination, reclassification, exchange, subdivision or other change.
(c)Subdivision or Combination of Shares. If the Company at any time shall combine or subdivide its Common Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased and the number of shares for which this Warrant is exercisable shall be proportionately increased, or (ii) in the case of a combination, the Exercise Price shall be proportionately increased and the number of shares for which this Warrant is exercisable shall be proportionately decreased.
(d)Dividends. If the Company at any time while this Agreement is outstanding and unexpired shall:
(i) pay a dividend with respect to the Common Stock payable in additional shares of Common Stock, then the Exercise Price shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution, and the number of shares of Common Stock for which this Warrant is exercisable shall be proportionately increased; or
(ii) make any other dividend or distribution on or with respect to Common Stock, except any dividend or distribution (A) in cash, or (B) specifically provided for in any other clause of this Section 8, then, in each such case, provision shall be made by the Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a proportionate share of any such dividend or distribution as though it were the holder of the Common Stock (or other stock for which the Common Stock is convertible) as of the record date fixed for the determination of the shareholders of the Company entitled to receive such dividend or distribution.
(e)Notice of Certain Events. If: (i) the Company shall declare any dividend or distribution upon its outstanding Common Stock, payable in stock, cash, property or other securities; (ii) the Company shall offer for subscription pro rata to holders of its Common Stock
5



any additional shares of stock of any class or other rights; (iii) there shall be any Merger Event; or (iv) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall give the Warrantholder notice thereof at the same time and in the same manner as it gives notice thereof to the holders of outstanding Common Stock. In addition, if at any time the number of shares of Common Stock (or other securities of any other class or classes of securities of the Company for which this Warrant is then exercisable) outstanding is reduced such that the number of shares of Common Stock or other securities issuable upon exercise of this Warrant shall exceed five percent (5%) of the then outstanding class of such securities, then, within three (3) business days of such event, the Company shall give the Warrantholder written notice thereof.
SECTION 9.REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.
(a)Reservation of Common Stock. The Company covenants and agrees that all shares of Common Stock that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any nature whatsoever; provided, that the Common Stock issuable pursuant to this Agreement may be subject to restrictions on transfer under state and/or federal securities laws. The Company has made available to the Warrantholder true, correct and complete copies of its Charter and bylaws currently in effect. The issuance of certificates or book-entry credit for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Warrantholder for any issuance tax in respect thereof, or other cost incurred by the Company in connection with such exercise and related issuance of shares of Common Stock. The Company further covenants and agrees that the Company will, at all times during the term hereof, have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant.
(b)Due Authority. The execution and delivery by the Company of this Agreement and the performance of all obligations of the Company hereunder, including the issuance to the Warrantholder of the right to acquire the shares of Common Stock, have been duly authorized by all necessary corporate action on the part of the Company. This Agreement: (i) does not violate the Charter or the Company’s current bylaws; (ii) does not contravene any law or governmental rule, regulation or order applicable to the Company; and (iii) except as could not reasonably be expected to have a Material Adverse Effect (as defined in the Loan Agreement), does not and will not contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument to which the Company is a party or by which it is bound. This Agreement constitutes a legal, valid and binding agreement of the Company, enforceable in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity, regardless of whether considered in a proceeding in equity or at law.
(c)Consents and Approvals. No consent or approval of, giving of notice to, registration with, or taking of any other action in respect of any state, federal or other governmental authority or agency is required with respect to the execution, delivery and performance by the Company of its obligations under this Agreement, except for the filing of notices pursuant to Regulation D under the Act and any filing required by applicable state securities law, which filings will be effective by the time required thereby.
(d)Exempt Transaction. Subject to the accuracy of the Warrantholder’s representations in Section 10, the issuance of the Common Stock upon exercise of this Agreement will constitute a transaction exempt from (i) the registration requirements of Section 5 of the Act, in reliance upon Section 4(a)(2) thereof, and (ii) the qualification requirements of the applicable state securities laws.
(e)Information Rights. At all times (if any) after the Loan Agreement has been terminated and prior to the earlier to occur of (x) the date on which all shares of Common Stock issued on exercise of this Warrant have been sold, or (y) the expiration or earlier termination of this Warrant, when the Company shall not be required to file reports pursuant to Section 13 or
6



15(d) of the Exchange Act or shall not have timely filed all such required reports, the Warrantholder shall be entitled to the information rights contained in Sections 7.1(b), 7.1(c) and 7.1(f) of the Loan Agreement, and in any such event Sections 7.1(b), 7.1(c) and 7.1(f) of the Loan Agreement are hereby incorporated into this Agreement by this reference as though fully set forth herein, provided, however, that the Company shall not be required to deliver a Compliance Certificate once all Indebtedness (as defined in the Loan Agreement) owed by the Company to the Warrantholder has been repaid. For the avoidance of doubt, the Company shall not be required to deliver any information contained in Sections 7.1(b), 7.1(c) and 7.1(f) of the Loan Agreement if it has timely filed all required reports under Section 13 or 15(d) of the Exchange Act.

(h)Entire Agreement; Amendments. This Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter hereof. None of the terms of this Agreement may be amended except by an instrument executed by each of the parties hereto.
(i)Headings. The various headings in this Agreement are inserted for convenience only and shall not affect the meaning or interpretation of this Agreement or any provisions hereof.
(j)Advice of Counsel. Each of the parties represents to each other party hereto that it has discussed (or had an opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(n), 12(o), 12(p), 12(q) and 12(r).
(k)No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto
9



and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.
(l)No Waiver. No omission or delay by the Warrantholder at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by the Company at any time designated, shall be a waiver of any such right or remedy to which the Warrantholder is entitled, nor shall it in any way affect the right of the Warrantholder to enforce such provisions thereafter during the term of this Agreement.
(m)Survival. All agreements, representations and warranties contained in this Agreement or in any document delivered pursuant hereto shall be for the benefit of the Warrantholder and shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.
(n)Governing Law. This Agreement has been negotiated and delivered to the Warrantholder in the State of California, and shall be deemed to have been accepted by the Warrantholder in the State of California. Delivery of Common Stock to the Warrantholder by the Company under this Agreement is due in the State of California. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.
(o)Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Agreement may be brought in any state or federal court of competent jurisdiction located in the State of California. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (i) consents to personal jurisdiction in Santa Clara County, State of California; (ii) waives any objection as to jurisdiction or venue in Santa Clara County, State of California; (iii) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (iv) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the requirements for notice set forth in Section 12(g), and shall be deemed effective and received as set forth in Section 12(g). Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.
(p)Mutual Waiver of Jury Trial. Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes arising under or in connection with this Warrant be resolved by a judge applying such applicable laws. EACH OF THE COMPANY AND THE WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST THE WARRANTHOLDER OR ITS ASSIGNEE OR BY THE WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY RELATING TO THIS WARRANT. This waiver extends to all such Claims, including Claims that involve persons or entities other the Company and the Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and the Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement.
(q)Arbitration. If the Mutual Waiver of Jury Trial set forth in Section 12(p) is ineffective or unenforceable, the parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator shall be a retired California state judge or a retired Federal court judge. Such proceeding shall be conducted in Santa Clara County, State of California, with California rules of evidence and discovery applicable to such arbitration. The decision of the arbitrator shall be binding on the parties, and shall be final and nonappealable to the maximum extent permitted by law. Any judgment rendered by the arbitrator may be entered
10



in a court of competent jurisdiction and enforced by the prevailing party as a final judgment of such court.
(r)Pre-arbitration Relief. In the event Claims are to be resolved by arbitration, either party may seek from a court of competent jurisdiction identified in Section 12(o), any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by binding arbitration.
(s)Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts (including by facsimile or electronic delivery (PDF), and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument.
(t)Specific Performance. The parties hereto hereby declare that it is impossible to measure in money the damages which will accrue to the Warrantholder by reason of the Company’s failure to perform any of the obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by the Warrantholder. If the Warrantholder institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action or proceeding is brought hereby waives the claim or defense therein that the Warrantholder has an adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.
(u)Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.
(v)Legends. To the extent required by applicable laws, this Warrant and the shares of Common Stock issuable hereunder (and the securities issuable, directly or indirectly, upon conversion of such shares of Common Stock, if any) may be imprinted with a restricted securities legend in substantially the following form:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION RELATED THERETO OR, SUBJECT TO SECTION 11 OF THE WARRANT AGREEMENT DATED MARCH 15, 2024, BETWEEN THE COMPANY AND [____________], AN OPINION OF COUNSEL (WHICH MAY BE COMPANY COUNSEL) REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACTOR ANY STATE SECURITIES LAWS.

SOMERVILLE, Mass. – August 14, 2024 – bluebird bio, Inc. (NASDAQ: BLUE) (“bluebird bio” or the “Company”) today reported second quarter results and business highlights for the quarter ended June 30, 2024, including recent commercial and operational progress.

“We are seeing clear evidence that our commercial launch is accelerating, with over 20 cell collections completed in sickle cell disease and beta-thalassemia to date in 2024, and more than 40 additional patients already scheduled to initiate the treatment journey for a bluebird gene therapy by the end of this year,” said Andrew Obenshain, chief executive officer, bluebird bio. “We are further encouraged by the commitment to provide patient access across both commercial and government payers, most recently conveyed through multiple positive Medicaid decisions and the growing number of published coverage policies for LYFGENIA, and we expect approximately 85 patient starts across our portfolio this year.”

COMMERCIAL LAUNCH UPDATES

LYFGENIA™ launch building (lovotibeglogene autotemcel); continued commercial momentum for ZYNTEGLO™ (betibeglogene autotemcel) and SKYSONA™ (elivaldogene autotemcel)

27 patient starts completed across portfolio to date in 2024 (19 ZYNTEGLO, 4 LYFGENIA, 4 SKYSONA).
Launch momentum building with more than 40 additional patients scheduled for cell collection across commercial portfolio through year end.
Successfully completed manufacturing and release testing for first commercial LYFGENIA patient and the first infusion is being scheduled.
Rapid acceleration projected for ZYNTEGLO following the recent approval of additional manufacturing capacity.

Validated access and reimbursement strategy is driving favorable coverage landscape

Significant progress with formalized paths to market access. To date, more than half of Medicaid-insured individuals with sickle cell disease in the U.S. live in a state that has affirmed coverage for LYFGENIA through a preferred drug list or published coverage criteria.





Nearly 20% of Medicaid-insured individuals with sickle cell disease in the U.S. live in a state that has already completed prior authorization approval for the use of LYFGENIA for at least one patient.
Multiple outcomes-based agreements are published and in place for LYFGENIA with national commercial payer organizations, representing more than 200 million U.S. lives.
Timely access to ZYNTEGLO and SKYSONA has continued, with zero ultimate denials to date for either therapy across both Medicaid and commercial payers.

Substantial QTC footprint established

bluebird has activated more than 70 total QTCs for LYFGENIA and ZYNTEGLO (defined as a signed MSA).
Six centers are activated to administer SKYSONA for patients with cerebral adrenoleukodystrophy (CALD).

2024 GUIDANCE

The Company anticipates approximately 85 patient starts (cell collections) combined across its portfolio of three FDA approved therapies (LYFGENIA, ZYNTEGLO, SKYSONA) in 2024. Consistent with previous quarters, bluebird plans to provide quarterly updates on patient starts by indication for each of its therapies.
The Company continues to anticipate gross-to-net discounts across all three products to be in the range of 20% to 25% of gross revenue in 2024 and expects they will fluctuate based on product and payer mix, as well as utilization of outcomes-based agreements for LYFGENIA and ZYNTEGLO.





Based on projected timelines from cell collection to infusion, the Company anticipates recognizing revenue from its first infusion of LYFGENIA in the third or fourth quarter of 2024.

SECOND QUARTER FINANCIAL HIGHLIGHTS

Cash Position: The Company’s cash, cash equivalents and restricted cash balance was approximately $193 million, including restricted cash of approximately $49 million, as of June 30, 2024.

Based on current operating assumptions, bluebird expects its cash and cash equivalents as of June 30, 2024 will be sufficient to fund its operations into the second quarter of 20251, not accounting for the cash minimums required under the Company’s loan agreement with Hercules Capital, Inc. and excluding receipt of any future tranches under the agreement.

The Company has also renegotiated certain terms of its loan agreement with Hercules Capital, Inc. and is eligible to receive two future tranches totaling $50 million, contingent upon achievement of patient start and product delivery milestones and completion of additional financing. These tranches take the place of previously agreed tranches tied to patient starts and gross profit.

Revenue, net: Total revenue, net was $16.1 million for the three months ended June 30, 2024, compared to $6.9 million for the three months ended June 30, 2023. The increase of $9.2 million was due to increased ZYNTEGLO product revenue.

On March 26, 2024, bluebird announced that it will restate its consolidated financial statements as of and for the year ended December 31, 2022, and for each of the first three quarters of 2022 and 2023 in its Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K"). The restatements relate to the identification of leases and the treatment of non-lease components contained in lease agreements. The restatement is not expected to impact the Company’s cash position or revenue. As a result of the restatement, the Company is delayed in filing its 2023 Form 10-K and its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024 (the “Q1 2024 Form 10-Q") and June 30, 2024 (the “Q2 2024 Form 10-Q”). The Company is continuing to work expeditiously to complete these filings.

The financial results included in this press release represent the most current information available to the Company’s management. The Company expects that its actual results to be reported in its Q2 2024 Form 10-Q will not differ materially from the results included herein, however, these results are subject to change following the completion of the Company’s financial close procedures and the review of its consolidated financial statements for the quarter ended June 30, 2024.

CONFERENCE CALL DETAILS

bluebird will hold a conference call to discuss its second quarter 2024 results and business updates today, Wednesday, August 14, 2024, at 8:00 am ET.

1 Taking into account the minimum cash requirements under the Company’s loan agreement with Hercules Capital, Inc., bluebird expects its cash and cash equivalents will be sufficient to fund its operations into the first quarter of 2025.

Forward-Looking Statements
This press release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements that are not statements of historical facts are, or may be deemed to be, forward-looking statements, such as statements regarding the number of anticipated patient starts across bluebird’s portfolio of therapies; the Company’s anticipated cash runway; the Company’s expectations regarding its ability to maintain compliance with, and access future tranches under, its term loan facility; the Company’s expectations with respect to the commercialization of its products, including without limitation, the acceleration of patient starts, the timing of revenue recognition, anticipated gross-to-net discounts; and the Company’s ability to establish favorable coverage for its therapies; and expectations regarding the Company’s restatement of certain historical financial statements and the timing for filing of its 2023 Form 10-K, Q1 2024 Form 10-Q and Q2 2024 Form 10-Q. Such forward-looking statements are based on historical performance and current expectations and projections about bluebird’s future goals, plans and objectives and involve inherent risks, assumptions and uncertainties, including internal or external factors that could delay, divert or change any of them in the next several years, that are difficult to predict, may be beyond bluebird’s control and could cause bluebird’s future goals, plans and objectives to differ materially from those expressed in, or implied by, the statements. No forward-looking statement can be guaranteed. Forward-looking statements in this press release should be evaluated together with the many risks and uncertainties that affect bluebird bio’s business, particularly those identified in the risk factors discussion in bluebird bio’s Annual Report on Form 10-K for the year ended December 31, 2022, as updated by its





subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the Securities and Exchange Commission, including our Prospectus Supplement, dated December 19, 2023. These risks and uncertainties include, but are not limited to: delays and challenges in bluebird’s commercialization and manufacturing of its products, including challenges in manufacturing vector for ZYNTEGLO and SKYSONA to meet current demand; the internal and external costs required for bluebird’s ongoing and planned activities, and the resulting impact on expense and use of cash, has been, and may in the future be, higher than expected, which has caused bluebird, and may in the future cause bluebird, to use cash more quickly than it expects or change or curtail some of its plans or both; substantial doubt exists regarding bluebird’s ability to continue as a going concern; bluebird’s expectations as to expenses, cash usage and cash needs may prove not to be correct for other reasons such as changes in plans or actual events being different than bluebird’s assumptions; the risk that additional funding may not be available on acceptable terms, or at all; risks related to bluebird's loan agreement, including the risk that operating restrictions could adversely affect bluebird's ability to conduct its business, the risk that bluebird will not achieve milestones required to access future tranches under the agreement, and the risk that bluebird will fail to comply with covenants under the agreement, including with respect to required cash and revenue levels, which could result in an event of default; the risk that the efficacy and safety results from bluebird’s prior and ongoing clinical trials will not continue or be seen in the commercial context; the risk that the QTCs experience delays in their ability to enroll or treat patients; the risk that bluebird experiences delays in establishing operational readiness across its supply chain ; the risk that there is not sufficient patient demand or payer reimbursement to support continued commercialization of the Company’s therapies; the risk of insertional oncogenic or other safety events associated with lentiviral vector, drug product, or myeloablation, including the risk of hematologic malignancy; the risk that bluebird’s products, including LYFGENIA, will not be successfully commercialized; and risks related to compliance with Nasdaq continued listing requirements. The forward-looking statements included in this document are made only as of the date of this document and except as otherwise required by applicable law, bluebird bio undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise.
