Exact Sciences (NASDAQ: EXAS) earnings show why Abbott moved now on a $21bn diagnostics acquisition

Exact Sciences Corp. (NASDAQ: EXAS) reported record fourth quarter and full-year 2025 financial results, delivering $878 million in fourth quarter revenue and $3.25 billion in full-year revenue as operating cash flow and free cash flow turned structurally positive ahead of its pending acquisition by Abbott Laboratories. The results confirm that Exact Sciences entered the acquisition phase with accelerating screening momentum, improving cash discipline, and a maturing precision oncology portfolio rather than as a turnaround asset. For Abbott Laboratories, the timing underscores that the $21 billion acquisition targets a scaled diagnostics platform with near-term cash generation rather than a speculative growth bet.

How Exact Sciences’ 2025 financial performance reframes the acquisition narrative from rescue to strategic timing

Exact Sciences’ 2025 results materially alter how the pending Abbott Laboratories acquisition should be interpreted by investors and policymakers. The company delivered 18 percent full-year revenue growth to $3.25 billion while converting scale into cash, generating $491 million in operating cash flow and $357 million in free cash flow. This shift matters because it demonstrates that the core screening business has reached a point where commercial leverage is beginning to outweigh historical R&D intensity.

While Exact Sciences still reported a full-year net loss of $208 million, the adjusted EBITDA improvement of $77 million year over year and the $821 million improvement in net loss signal that margin expansion is no longer theoretical. The company’s cash balance of $965 million at year-end further reduces execution risk during the regulatory review of the merger.

From an acquisition perspective, these results reduce the risk that Abbott Laboratories is inheriting a capital-hungry diagnostics platform. Instead, Abbott is acquiring a business that has already absorbed its heaviest infrastructure investments and is beginning to monetize scale across screening volumes, logistics, and laboratory throughput.

Why screening revenue growth remains the primary valuation anchor despite precision oncology momentum

Screening remains the economic engine of Exact Sciences, accounting for $2.53 billion of 2025 revenue and $695 million in the fourth quarter alone. Growth of 26 percent in fourth quarter screening revenue confirms that Cologuard-driven volume expansion remains intact despite increased payer scrutiny and competitive noise around blood-based alternatives.

This matters because screening revenue carries structural advantages that precision oncology does not. Screening volumes are repeatable, guideline-anchored, and population-scale, creating predictable cash flows once logistics and marketing costs stabilize. Precision oncology, by contrast, is episodic and clinically complex, even when margins are attractive.

For Abbott Laboratories, this reinforces why colorectal cancer screening is the strategic beachhead rather than a peripheral asset. Screening allows Abbott to deploy its payer relationships, primary care reach, and global diagnostics distribution network in ways that precision oncology alone cannot.

How precision oncology is evolving from margin enhancer to strategic differentiation lever

Precision oncology revenue reached $717 million for the full year, growing at a mid-teens rate. While smaller than screening, this segment is increasingly central to Exact Sciences’ strategic identity rather than merely a revenue add-on.

The fourth quarter clinical updates on Oncodetect molecular residual disease testing and Oncoguard Liver validation reflect a pipeline that is moving from concept to clinically actionable positioning. The NSABP B-59 substudy data in triple-negative breast cancer highlights how molecular residual disease testing may shift post-surgical treatment monitoring rather than compete directly with established diagnostics.

For Abbott Laboratories, this portfolio offers optionality rather than immediate scale. Precision oncology allows Abbott to participate across the cancer care continuum, from early detection through recurrence monitoring, without needing to build an oncology-specific diagnostics stack from scratch.

What the Freenome licensing agreement signals about blood-based screening strategy and competitive risk

The expiration of the Hart-Scott-Rodino waiting period for the Freenome license agreement removes a regulatory overhang but introduces a strategic nuance. Exact Sciences has secured exclusive U.S. rights to Freenome’s blood-based colorectal cancer screening tests, subject to first-line FDA approval.

This positioning matters because it allows Exact Sciences to hedge against long-term modality shifts without cannibalizing its stool-based franchise prematurely. Blood-based screening remains clinically attractive but commercially unproven at scale, particularly in first-line screening populations.

Abbott Laboratories inherits this optionality without committing to near-term cannibalization. The structure ensures that blood-based screening becomes a portfolio expansion lever rather than a disruptive threat to existing volumes.

How free cash flow inflection changes execution risk heading into regulatory review

One of the most underappreciated elements of the 2025 results is the scale of free cash flow improvement. A 379 percent year-over-year increase in free cash flow suggests that Exact Sciences has crossed an internal threshold where incremental revenue increasingly converts into cash rather than being absorbed by fixed costs.

This matters during the regulatory review phase of the Abbott Laboratories transaction. A company generating cash internally is less exposed to financing volatility, macro tightening, or integration delays. It also reduces the probability that Abbott will need to accelerate restructuring or cost rationalization immediately post-close.

For institutional investors, this strengthens confidence that the acquisition is accretive by design rather than dependent on aggressive post-merger intervention.

Why Abbott Laboratories is acquiring Exact Sciences now rather than waiting another cycle

Abbott Laboratories is paying $105 per share in cash, valuing Exact Sciences at approximately $21 billion in equity value. The decision to act now rather than wait reflects several converging factors.

First, Exact Sciences has reached sufficient scale to be operationally stable but remains early enough in global expansion that Abbott can shape commercialization strategy. Second, the diagnostics market is increasingly consolidating around platforms rather than single assays, and Exact Sciences offers a multi-modal portfolio across screening, molecular diagnostics, and genetic testing.

Third, competitive pressure from diversified diagnostics players is intensifying. Waiting risks allowing rivals to partner, license, or acquire adjacent assets that dilute strategic differentiation.

What happens next if regulatory approval proceeds as planned or stalls

The transaction remains subject to shareholder approval and regulatory clearance, with closing targeted for the second quarter of 2026. If approvals proceed on schedule, Abbott Laboratories will add a diagnostics growth engine that lifts its diagnostics segment beyond $12 billion in annual revenue.

If regulatory review extends or conditions are imposed, Exact Sciences’ financial trajectory reduces downside risk. The company is not dependent on the transaction for operational viability, which strengthens its negotiating position and limits forced concessions.

From a policy standpoint, the deal will likely be scrutinized for competitive impact in colorectal cancer screening. However, the presence of multiple screening modalities and emerging blood-based competitors may temper concerns about market concentration.

How investor sentiment and Exact Sciences share price behavior are evolving ahead of the Abbott merger vote

Exact Sciences shares have increasingly traded as a deal-anchored security rather than a pure growth stock since the November 2025 announcement. The 2025 results reduce the probability of downside repricing driven by operational weakness, reinforcing confidence in the transaction value.

Abbott Laboratories investors, meanwhile, are likely to focus on integration discipline and capital allocation rather than near-term earnings dilution. The company’s framing of the acquisition as immediately accretive to revenue growth and gross margin aligns with this expectation, provided execution remains controlled.

What this signals about the future structure of cancer diagnostics markets

The combination of Abbott Laboratories and Exact Sciences reflects a broader shift in cancer diagnostics toward vertically integrated platforms that span screening, diagnosis, and monitoring. Standalone diagnostics companies increasingly face scale disadvantages in payer negotiations, regulatory engagement, and global commercialization.

This transaction signals that the next phase of competition will be defined less by individual test performance and more by ecosystem integration, data leverage, and longitudinal patient engagement.
