The Acquisition Playbook.

Three patterns run through Akebia Therapeutics's acquisitions — what it looks for, how it pays, and how it folds in what it buys.

01
Acquisition criteria
Portfolio building through structure, not sprawl.
Akebia's two disclosed deals were both about assembling a complete kidney-disease portfolio rather than accumulating unrelated assets. The Keryx merger paired an FDA-approved oral CKD product (Auryxia) with Akebia's late-stage HIF-PHI candidate vadadustat; management said the combination would create 'a fully integrated biopharmaceutical company focused on chronic kidney disease.'

02
Capital deployment
Merger of equals rather than takeover.
The 2018 Keryx transaction was explicitly structured as an all-stock merger of equals — each Keryx share converted into 0.37433 Akebia shares, leaving Keryx holders with 50.6% of the combined company versus 49.4% for Akebia holders. Akebia surviving entity kept its name and CEO, but governance was shared, with Keryx appointing the board chairperson.

03
Integration approach
From marketed products to a rare-disease pipeline.
Seven years after the Keryx merger, Akebia used a cash-and-milestones asset purchase to enter rare kidney disease, buying worldwide rights to Q32 Bio's tissue-targeted complement inhibitor ADX-097 (renamed AKB-097). CEO John Butler framed it as the second pillar of strategy — 'to build and progress our kidney disease pipeline' — alongside commercializing Vafseo.

The Full Deal Book

2 acquisitions — each with the deal value, financing structure, target revenue, and executive commentary where disclosed.

01 Keryx Biopharmaceuticals, Inc. · Boston, Massachusetts, USA $1.3B
Announced Jun 2018 Closed Dec 2018 All stock
FDA-approved oral CKD therapy (Auryxia / ferric citrate)commercial infrastructure and renal sales forcelate-stage HIF-PHI development pipeline (vadadustat)

Akebia combined with Keryx Biopharmaceuticals in an all-stock merger of equals, with Keryx becoming a wholly owned subsidiary of Akebia and Akebia surviving as the combined company (still named Akebia Therapeutics, Inc.). The transaction was structured through Alpha Therapeutics Merger Sub, Inc., which merged into Keryx. It consolidated Keryx's FDA-approved oral CKD product Auryxia (ferric citrate) with Akebia's investigational Phase 3 oral HIF-PHI candidate vadadustat under one renal-focused company. All-stock merger of equals; implied pro forma equity value of approximately $1.3 billion (based on Keryx and Akebia closing prices on June 27, 2018, assuming full conversion of Keryx's convertible notes). No cash consideration except cash in lieu of fractional shares.

Why it was attractive
  • Auryxia was the only oral iron tablet approved in the U.S. for both hyperphosphatemia in dialysis-dependent CKD and iron deficiency anemia in non-dialysis-dependent CKD
  • giving the combined company an approved
  • revenue-generating renal product plus commercial infrastructure
The strategic and financial drivers of this merger are compelling. The combined company will have an expanded and highly complementary nephrology portfolio, with Auryxia, a product with significant growth opportunity, and vadadustat, an investigational late-stage HIF-PHI that has the potential to provide a new oral standard of care to patients with anemia due to CKD.John P. Butler — President and Chief Executive Officer, Akebia Therapeutics
Bringing Keryx together with Akebia represents a unique, value-enhancing opportunity for stakeholders of both companies. Akebia shareholders gain access to the only oral iron tablet approved in the United States to treat dialysis dependent CKD patients for hyperphosphatemia and non-dialysis dependent CKD patients for iron deficiency anemia.Jodie Morrison — Interim Chief Executive Officer, Keryx Biopharmaceuticals
02 Q32 Bio (ADX-097 / AKB-097 program) · USA (Q32 Bio Inc., Nasdaq: QTTB) $7.0M
Announced Dec 2025 Closed Nov 2025 Cash upfront plus contingent milestone and royalty payments
Clinical-stagetissue-targeted complement inhibitor (anti-C3d-Factor H fusion protein) with potential applicability across complement-mediated rare kidney diseases

Akebia entered into an Asset Purchase Agreement with Q32 Bio Inc. and Q32 Bio Operations Inc. under which it purchased and assumed substantially all of the assets and liabilities related to the research, development, manufacture and commercialization of Q32's clinical-stage candidate ADX-097 worldwide. ADX-097 (renamed AKB-097) is a tissue-targeted C3d-Factor H fusion protein complement inhibitor that has been evaluated in a Phase 1 trial in healthy volunteers and is intended to treat rare kidney diseases. The purchase established Akebia's rare kidney disease pipeline alongside praliciguat. Cash plus milestones and royalties: $7.0 million upfront on closing, plus a further $3.0 million upfront at the six-month anniversary; up to $94.5 million in development and regulatory milestones; up to $487.5 million in commercial (net-sales) milestones; and tiered royalties ranging from low-single-digit to mid-teen percentages of net sales.

Why it was attractive
  • ADX-097 is tissue-targeted to sites of complement activation and is not expected to cause the systemic complement inhibition seen with other inhibitors
  • giving Akebia a differentiated
  • next-generation asset with potential across a wide range of complement-mediated rare kidney diseases
Our commitment to patients with kidney disease is supported by two pillars of our corporate strategy: first, to drive Vafseo to become standard of care in anemia due to CKD in dialysis, and second, to build and progress our kidney disease pipeline. We are excited to take an important step forward as a company with the establishment of our rare kidney disease development pipeline.John P. Butler — Chief Executive Officer, Akebia Therapeutics
