Item 1.01.

Entry into a Material Definitive Agreement.

Merger Agreement

On July 6, 2026, Vertex Pharmaceuticals Incorporated, a Massachusetts corporation (“Parent”), Clark Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and Crinetics Pharmaceuticals, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Subject to the terms of the Merger Agreement, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Capitalized terms used herein and not otherwise defined herein have the meanings set forth in the Merger Agreement.

On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock of the Company, par value $0.001 per share (the “Shares”) issued and outstanding immediately prior to the Effective Time (other than Shares owned by the Company or any subsidiary of the Company immediately prior to the Effective Time, Shares owned by Parent, Merger Sub or any other subsidiary of Parent immediately prior to the Effective Time, and Shares held by any person who is entitled to demand, and has properly demanded, appraisal in respect of such Shares pursuant to applicable law) will be canceled and automatically converted into the right to receive $85.00 per share in cash, without interest thereon and subject to applicable withholding taxes (the “Merger Consideration”). Immediately prior to the Effective Time, all outstanding unvested stock options and unvested restricted stock units of the Company will become fully vested, and at the Effective Time, each outstanding stock option having a per share exercise price less than the Merger Consideration and restricted stock unit of the Company will be canceled and converted into the right to receive an amount in cash equal to the Merger Consideration (or, in the case of stock options, the difference between the Merger Consideration and the applicable per share exercise price), less any applicable withholding taxes. Any stock option having a per share exercise price equal to or greater than the Merger Consideration will be canceled for no consideration.

Consummation of the Merger is subject to various conditions set forth in the Merger Agreement, including (a) the adoption of the Merger Agreement by the holders of at least a majority of the outstanding Shares entitled to vote thereon (the “Company Stockholder Approval”), (b) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and any required foreign regulatory clearances, (c) the absence of any legal restraint preventing or prohibiting the consummation of the Merger, (d) the accuracy of each party’s representations and warranties contained in the Merger Agreement (subject to certain materiality and material adverse effect qualifications), (e) each party’s performance in all material respects of its obligations under the Merger Agreement and (f) no Company Material Adverse Effect having occurred that is continuing at the Effective Time. The consummation of the Merger is not subject to a financing condition.

The parties expect the Merger and the other transactions contemplated by the Merger Agreement (collectively, the “Transactions”) to close in the third quarter of 2026. The Merger Agreement provides that as promptly as reasonably practicable (and in any event within 10 Business Days) after the date of the Merger Agreement, the Company will prepare and file with the U.S. Securities and Exchange Commission (the “SEC”) a preliminary proxy statement in connection with the Merger and will, subject to the terms and conditions of the Merger Agreement, convene a special meeting of the Company’s stockholders (the “Company Stockholder Meeting”) for the purpose of voting upon the adoption of the Merger Agreement.

The Merger Agreement contains customary representations and warranties by Parent, Merger Sub and the Company. The Merger Agreement also contains customary covenants and agreements, including with respect to the operations of the business of the Company between signing and closing, governmental filings and approvals, preparation and filing of the proxy statement, convening and holding the Company Stockholder Meeting, financing cooperation and other matters.

The Merger Agreement contains customary non-solicitation restrictions prohibiting the Company’s solicitation of alternative business combination transactions and restricts the Company’s ability to furnish non-public information to, or participate in any discussions or negotiations with, any third party with respect to any such transaction, subject to customary exceptions in the event of an acquisition proposal that the Board of Directors of the Company determines constitutes, or would reasonably be expected to lead to, a Superior Company Proposal (as defined in the Merger Agreement).

The Merger Agreement contains termination rights for each of Parent, Merger Sub and the Company including by either Parent or the Company if the Effective Time shall not have occurred on or before January 6, 2027 (subject to automatic extension for three months under specified circumstances) or if the Company Stockholder Approval is not obtained at the Company Stockholder Meeting, or by the Company to enter into an alternative transaction that constitutes a Superior Company Proposal, and further provides that upon termination of the Merger Agreement under specified circumstances the Company may be required to pay Parent a termination fee of $350,474,425, which circumstances include (i) a termination by the Company to accept and enter into a definitive agreement with respect to a Superior Company Proposal, (ii) a termination by Parent due to an Adverse Recommendation Change or an Intervening Event Adverse Recommendation and (iii) if the Merger Agreement is terminated under certain specified circumstances and prior to such termination a Company Takeover Proposal is proposed or announced or becomes known to the Board (and is not subsequently withdrawn) and the Company enters into a definitive agreement for, or consummates, a transaction involving a Company Takeover Proposal within twelve months of such termination.

A copy of the Merger Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Merger Sub or Parent. The representations, warranties and covenants contained in the Merger Agreement were made only as of specified dates for the purposes of the Merger Agreement, were solely for the benefit of the parties to the Merger Agreement and may be subject to qualifications and limitations agreed upon by such parties. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement may be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC and are qualified by information in confidential disclosure schedules provided by the parties thereto in connection with the signing of the Merger Agreement. These disclosure schedules include information that modifies, qualifies and creates exceptions to the representations, warranties and covenants set forth in the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement were used for the purpose of allocating risk between the Company, Merger Sub and Parent, rather than establishing matters of fact. Accordingly, the representations and warranties in the Merger Agreement may not constitute the actual state of facts about the Company, Merger Sub or Parent.

Financing of the Merger

Parent expects to finance the Merger with a combination of cash on hand and new debt financing. In connection with, and concurrently with entry into, the Merger Agreement, Parent entered into a debt commitment letter dated July 6, 2026 (the “Debt Commitment Letter”) with Bank of America, N.A., BofA Securities, Inc. and Morgan Stanley Senior Funding, Inc. (collectively, the “Banks”) pursuant to which the Banks have agreed to provide Parent with an unsecured 364-day bridge loan facility (the “Bridge Financing”) in an aggregate principal amount of $4.5 billion on the terms and subject to the conditions set forth in the Debt Commitment Letter for the purposes of financing the transactions contemplated by the Merger Agreement. The obligations of the Banks to provide the debt financing under the Debt Commitment Letter are subject to conditions customary for a transaction of this type. The Bridge Financing will be available to be drawn upon in the event that Parent and its subsidiaries have not prior to or concurrently with consummation of the Merger received proceeds from permanent financing sufficient to finance the transactions contemplated by the Merger Agreement, which is expected to be an unsecured delayed draw term loan facility. The Merger Agreement requires each of Parent and Merger Sub to use, and to cause their respective affiliates to use, reasonable best efforts to obtain the proceeds of the Bridge Financing. The Merger is not conditioned on Parent’s receipt of the Bridge Financing or any other financing. Pursuant to the Merger Agreement, the Company is required to use reasonable best efforts to provide Parent with customary cooperation in connection with the Bridge Financing.

Item 7.01.

Regulation FD.

On July 6, 2026, Parent held a conference call, commencing at 4:30 p.m. Eastern time, to its investors, which included an investor presentation. A copy of the investor presentation is attached hereto as Exhibit 99.1.

The information contained in this Item 7.01 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 Exchange Act or the Securities Act of 1933, as amended, whether made before or after the date hereof, except as shall be expressly set forth by specific reference in such filing.

Item 8.01.

Other Events.

Cautionary Notice Regarding Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 related to the Company, Parent and the Transactions that are subject to risks, uncertainties and other factors. While Parent believes the forward-looking statements contained in this Current Report on Form 8-K are accurate, these forward-looking statements represent the beliefs of the Company and Parent only as of the date of this Current Report on Form 8-K, and there are a number of risks and uncertainties that could cause actual events or results to differ materially from those expressed or implied by such forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including all statements regarding the intent, belief or current expectation of the companies’ and members of their senior management teams. Forward-looking statements are not purely historical and may be accompanied by words such as “anticipates,” “may,” “forecasts,” “expects,” “intends,” “plans,” “potentially,” “believes,” “seeks,” “estimates,” and other words and terms of similar meaning. Such statements may include the statements made by Reshma Kewalramani, M.D. and Scott Struthers, Ph.D. in the joint press release attached hereto as Exhibit 99.2, and statements that relate to, but are not limited to: the benefits of Parent’s proposed acquisition of the Company and associated integration plans; the expected timing of the completion of the Transactions and other transactions contemplated by the Merger Agreement; the commercial potential of PALSONIFY and the anticipated potential of atumelnant and the Company’s other pipeline assets, including the potential for PALSONIFY to redefine the treatment paradigm in acromegaly and for atumelnant to become the leading therapy for people struggling with CAH; expectations that the Transactions will accelerate Parent’s revenue growth and enhance Parent’s long-term earnings profile, including the potential for more than $5 billion in annual revenue, and support Parent’s goal of sustained double digit revenue growth; expectations that the Transactions will become accretive to non-GAAP operating income in 2029; expectations for Parent’s financing of the Transactions, including support by the fully committed bridge financing; and any assumptions underlying any of the foregoing.

Forward-looking statements are subject to certain risks, uncertainties, or other factors that are difficult to predict and could cause actual events or results to differ materially from those indicated in any such statements due to a number of risks and uncertainties. Those risks and uncertainties that could cause the actual results to differ from expectations contemplated by forward-looking statements include, among other things: the occurrence of any event or circumstance that could give rise to the right of the Company or Parent to terminate the Merger Agreement, including circumstances requiring payment of a termination fee pursuant to the Merger Agreement; failure to obtain applicable regulatory or the Company’s stockholder approval in a timely manner or otherwise; the risk that the Transactions may not close in the anticipated timeframe or at all due to one or more of the other closing conditions not being satisfied or waived; the possibility that competing offers will be made; the risk that there may be unexpected costs, charges or expenses resulting from the Transactions; risks related to the ability of the Company and Parent to successfully integrate the businesses and the possibility that integration may be more difficult, time consuming or costly than expected; the risk that the Transactions disrupt the Company’s or Parent’s current plans and operations; the risk that certain restrictions during the pendency of the proposed transaction may impact the Company’s ability to pursue certain business opportunities or strategic transactions; risks related to disruption of each company’s management’s time and attention from ongoing business operations due to the Transactions; the risk that any announcements relating to the Transactions could have adverse effects on the market price of the Company’s and/or Parent’s common stock, credit ratings or operating results; the risk of litigation that could be instituted against the parties or their respective directors, managers or officers and/or regulatory actions related to the Transactions, including the effects of any outcomes related thereto; the effects of the Transactions on relationships with employees, other business partners or governmental entities; the difficulty of predicting the timing or outcome of regulatory approvals or actions, if any; the impact of competitive products and pricing; that Parent may not realize the potential benefits of the Transactions; other business effects, including the effects of industry, economic or political conditions outside of the companies’ control; and actual or contingent liabilities related to the Transactions . In addition, the product candidates being developed by the Company are subject to all the risks inherent in the drug development process, and there can be no assurance that the development of these product candidates will be commercially successful. Forward-looking statements in this Current Report on Form 8-K should be evaluated together with the many uncertainties that affect Parent’s and the Company’s businesses, particularly those risks listed under the heading “Risk Factors” and the other cautionary factors discussed in the parties’ periodic reports filed with the SEC, including Parent’s and the Company’s annual reports on Form 10-K for the year ended December 31, 2025, and quarterly reports on Form 10-Q and current reports on Form 8-K, all of which are available

on the SEC’s website at www.sec.gov. You should not place undue reliance on these statements. All forward-looking statements are based on information currently available to Parent and the Company, and Parent and the Company disclaim any obligation to update the information contained in this Current Report on Form 8-K as new information becomes available, except as required by law.

~20,000 patients diagnosed with acromegaly in the U.S.; another 35,000+ outside the U.S. • A rare hormonal disease most often caused by a benign pituitary adenoma that leads to excess growth hormone; results in enlargement of hands and feet,

serious heart and metabolic problems, reduced quality of life, and shortened lifespan if untreated Serious disease • Surgery is first line therapy, but only ~40–50% of patients achieve durable remission, with many needing lifelong drug

therapy • If surgery is unsuccessful, somatostatin receptor ligands (SRLs) are used; SRLs bind to Clinically somatostatin receptors to reduce production of GH and insulin-like growth factor (IGF-1) validated target • Traditional SRLs are

large needle, intramuscular or deep subcutaneous injectables, with potential for breakthrough symptoms and low patient compliance; often administered by HCP • Available oral medicines have limitations including efficacy or are not indicated

for naïve patients • Thus, significant unmet need remains, driven by burdensome therapy, treatment-related side Significant effects, and persistent symptoms, even in patients considered “controlled” on available unmet need

• 1) high androgen levels can lead to complications such as short stature, acne, hirsutism, early puberty, infertility, and long-term physical and emotional burden • 2) high dose GCs can lead to heart disease, obesity, diabetes, bone

loss, other persistent QoL issues • Classic CAH is a group of autosomal recessive genetic diseases that result in a deficiency in the adrenal Well understood enzyme 21-hydroxylase (21-OH)* causal biology • No medicine currently approved

can durably normalize androgens and allow patients to be maintained on physiologic glucocorticoid doses • Recent market entrant suppresses upstream at the pituitary gland level, provides incomplete blockade of the pathway, and doesn’t

normalize A4 without supplementation of high dose glucocorticoids Significant • Atumelnant suppresses at the adrenal cortex and thus holds the promise for concurrent and sustained unmet need control of androgen A4 and low physiologic doses of

Atumelnant is an oral, small molecule antagonist targeting the ACTH

receptor Currently in pivotal development for adults with CAH and in Phase 2/3 for pediatrics Mechanism of action Hypothalamic-pituitary-adrenal axis • Adrenocorticotropic hormone (ACTH) receptor antagonist that selectively blocks the activity

of ACTH at adrenal gland • By blocking receptor activation, atumelnant suppresses synthesis of cortisol precursors and adrenal androgens atumelnant Differentiated profile from current therapies • Site of action: adrenal cortex enabling

both androgen control and physiologic glucocorticoid doses • Once-daily, oral medication • Reductions in additional disease markers such as 17- OHP while reducing glucocorticoid usage ACTH: adrenocorticotropic hormone; AVP: arginine

Atumelnant has potential to address significant unmet need and become

SoC in CAH Goal of disease-modifying therapy: normalize androgens (A4) at physiologic glucocorticoid (GC) doses — and maintain ü Atumelnant drove robust A4 reduction, sustained even with glucocorticoids reduced to physiologic

levels • High awareness of atumelnant Phase 2 data in CAH patients • Atumelnant target product profile (TPP) rated by HCPs as potential Market research future standard of care for CAH patients • Top reason HCPs select atumelnant

TPP is efficacy (75%): with target “efficacy data on A4 and GC reduction” endocrinologists • HCPs cite limitations of existing therapies to normalize A4 and reduce GC dosing to physiologic doses Sources: Crinetics ENDO 2026 / Jan
