Merck & Co. (MRK): $18B FCF Rebound vs. the Keytruda 2028 Test

Big Picture: A Powerful Cash-Flow Recovery Meets a 2028 Strategic Inflection#

Merck [MRK] closed FY2024 with a dramatic financial rebound: net income of $17.12B and free cash flow of $18.10B, representing a swing from the compressed earnings and cash generation of FY2023. According to Merck’s FY2024 results, revenue rose to $64.17B from $60.12B the prior year, a +6.74% increase that helped restore operating leverage and margins. That rebound, and the accompanying cash generation, re-establish the company’s financial flexibility just as Keytruda—Merck’s largest franchise—approaches an exclusivity and U.S. pricing inflection centered on 2028.

The tension is immediate and quantifiable: the company’s operating income recovered to $20.22B in FY2024 from $2.95B in FY2023, converting stronger top-line performance and lower R&D runway year-on-year into meaningful profit recovery. Free cash flow nearly doubled versus FY2023 (from $9.14B to $18.10B), giving management optionality for reinvestment, M&A, and dividend support. Yet the strategic problem persists: Keytruda’s potential revenue erosion from patent expiry and negotiated pricing under the Inflation Reduction Act creates a multi-year gap that Merck must bridge through pipeline launches, lifecycle management, and targeted acquisitions.

This article ties the FY2024 financial reset to the company’s strategic response. It quantifies balance-sheet strength and capital allocation flexibility, evaluates where new growth will need to come from, and highlights the execution risks that will determine whether Merck can convert a brief windfall in cash into a durable multi‑franchise profile beyond Keytruda.

Financial Performance: Profit, Margins and Cash Flow—The Numbers that Matter#

Merck’s FY2024 income statement shows clear recovery: revenue of $64.17B, gross profit of $48.98B, operating income of $20.22B, and net income of $17.12B. Calculating margins from those figures produces a gross margin of 76.32%, an operating margin of 31.51%, and a net margin of 26.68% for FY2024 (gross profit / revenue, operating income / revenue, net income / revenue). Those margins are a material step up from FY2023, when operating margin was 4.91% and net margin was 0.61%, illustrating how operational recovery amplified profitability.

Cash flow quality improved in tandem. Merck reported $21.47B of net cash provided by operating activities in FY2024 against $17.13B of reported net income, implying cash conversion above 100% for the year. Free cash flow of $18.10B (operating cash flow minus capital expenditures) nearly doubled from FY2023’s $9.14B. That strong free cash flow underpins both the company’s dividend commitments and the capacity to fund pipeline commercialization and selective M&A without materially increasing leverage.

Earnings-per-share dynamics deserve attention as well. Market quotes show a price of $85.09 and reported EPS figures of $6.49 (per the stock quote) and $6.53 on a TTM basis; using the TTM EPS produces a trailing P/E of ~13.03x, consistent with the market’s view that Merck currently trades at a modest multiple relative to its large-cap pharma peers. That multiple reflects a mix of restored cash generation and the market’s discount for the 2028 Keytruda uncertainty.

Balance Sheet & Leverage: Flexibility After a Volatile Cycle#

Merck’s FY2024 balance sheet shows total assets of $117.11B, total liabilities of $70.73B, and total stockholders’ equity of $46.31B, resulting in a calculated debt-to-equity ratio using total debt of $37.11B of 0.80x (total debt / stockholders’ equity). Net debt (total debt minus cash & short-term investments) stood at $23.87B. Using FY2024 EBITDA of $25.71B, a simple net-debt-to-EBITDA calculation yields ~0.93x, signaling modest leverage and ample headroom to absorb acquisition funding or temporary earnings pressure.

There are minor discrepancies between point-in-time calculations and certain TTM ratios reported elsewhere in the dataset (for example, a net-debt/EBITDA TTM metric of 1.05x and a debt-to-equity TTM of 72.09%). These differences likely reflect timing and definition variances—TTM metrics incorporate trailing quarters and different EBITDA adjustments versus single‑year FY figures—so readers should treat both sets of numbers as complementary rather than contradictory. On balance, the balance sheet is investment-grade in character: liquid, with manageable gross debt and declining net leverage versus the trough in 2023.

Capital deployment in FY2024 mirrored the balance between shareholder return and reinvestment. Dividends paid totaled $7.84B and share repurchases were $1.31B, while acquisitions and investing outflows (including $4.09B in net acquisitions) consumed cash. The allocation mix shows a priority on sustaining the dividend while preserving the ability to buy growth where management sees fit.

Strategic Context: Keytruda 2028 and the Company’s Multi‑Pronged Response#

Merck’s central strategic challenge is clear and time-bound: Keytruda faces both patent expiry risk and the impact of U.S. price negotiations under the Inflation Reduction Act that begin to bite in 2028. The company and external analyses (including the Monexa strategic review) quantify Keytruda peak sales in the multiple‑tens of billions—estimates have ranged into the low‑to‑mid $30B area depending on adoption and label expansion—so any material erosion would be a large headwind.

Management’s response is multi-dimensional. The company is pursuing lifecycle management for Keytruda—most notably a subcutaneous formulation intended to improve convenience and defend share—plus accelerated label expansions in adjuvant and neoadjuvant settings. At the same time, Merck is intensifying R&D and commercialization of next-generation oncology assets (including ADCs with Daiichi Sankyo), cardiovascular candidates such as MK‑0616, and vaccine programs. These plans are described in strategic reviews and management commentary published over 2024–2025 and summarized in Monexa’s analysis of Merck’s approach.

Those strategic levers are sensible and necessary, but they come with timing and execution risk. Most of the highest‑potential pipeline assets are mid‑to‑late clinical stage and will commercialize into the late 2020s and early 2030s, creating a multi-year gap between when Keytruda revenue could soften materially and when new franchises fully ramp. The company’s announced cost‑savings program—a target of roughly $3.0B of annual savings by end of 2027—acts as a financial bridge. That program should be viewed as a risk‑mitigating operational lever rather than a permanent replacement for lost product revenue.

Pipeline, M&A and Diversification: Where Growth Needs to Come From#

Merck’s pipeline mix is the core of its replacement strategy. The oncology ADC program (ifinatamab deruxtecan / I‑DXd) and other targeted oncology candidates are intended to restore meaningful oncology growth. The company projects material oncology revenue from ADCs and new targeted therapies across the 2030s, and analysts’ consensus estimates embedded in the dataset show revenue rising modestly across the mid‑to‑late decade in base cases.

On the inorganic side, the acquisition of Verona Pharma (summarized in Monexa’s write‑up) is an example of tactical diversification into cardio‑pulmonary care. Verona’s lead product, Ohtuvayre (ensifentrine), brings an inhaled COPD maintenance therapy and early commercial traction—useful recurring revenue that complements Merck’s respiratory pipeline. The acquisition size (reported as roughly $10B in strategic commentary) is meaningful but not transformational versus Keytruda volumes; it is, however, representative of Merck’s approach to add multiple mid‑single‑billion franchises rather than one mega replacement.

Other strategic diversifiers include Merck Animal Health, which generated roughly $5.9B in FY2024 sales and serves as a stable, mid‑single‑digit growth business. While Animal Health cannot replace Keytruda scale, it provides recurring cash flow and lowers consolidated cyclicality. The combined path to replacing projected Keytruda shortfalls is therefore a portfolio playbook: many modest-to-large contributors rather than a single replacement molecule.

Capital Allocation: Dividends, Buybacks and Acquisition Appetite#

Merck’s capital allocation in FY2024 balanced shareholder returns with reinvestment. The company paid $7.84B in dividends and repurchased $1.31B of stock, while funding $4.09B of net acquisitions and maintaining robust R&D spend (R&D expense of $17.94B in FY2024). Calculating the cash dividend as a share of net income gives a cash‑payout ratio of ~45.8% (dividends paid / net income), while using dividend per share (annualized $3.20) over reported EPS (6.49) points to a payout of ~49.30%. The difference reflects timing and accounting bases but both metrics indicate a payout below full earnings and free-cash-flow coverage that supports continuation of payments.

Leverage remains moderate. Using FY2024 figures, net debt/EBITDA computes to ~0.93x (net debt $23.87B / EBITDA $25.71B), leaving capacity for targeted bolt‑on deals without jeopardizing investment‑grade characteristics. Management’s recent M&A and the commitment to redeploy cost savings into launches imply a disciplined willingness to pay for strategic adjacency, not largescale transformational purchases that would materially increase leverage.

The practical implication for capital allocation is that Merck appears positioned to preserve the dividend while maintaining selective M&A and launch funding. However, management will likely constrain large-scale buybacks until the post‑Keytruda revenue trajectory becomes clearer, preferring to prioritize reinvestment into pipeline assets that can sustain mid‑to‑long-term growth.

Risks, Key Assumptions and Execution Triggers#

Merck’s upside depends on several binary or semi‑binary outcomes. Clinical readouts and regulatory approvals for ADCs and other late‑stage programs will be central to the upside case; setbacks would lengthen the period of earnings pressure. The subcutaneous Keytruda formulation, while promising from a convenience perspective, faces patent disputes (notably with Halozyme technologies used in SC delivery) and regulatory timing risk. The success of the $3.0B cost-savings program by 2027 is another execution hinge: partial savings would reduce the company’s margin cushion.

Macroeconomic and policy risks are also nontrivial. U.S. negotiated pricing under the Inflation Reduction Act represents an external driver that could compress revenue independent of Merck’s clinical or commercial execution. Additionally, competitive dynamics in oncology—with rival PD‑1/PD-L1 and ADC programs launching across multiple players—will pressure pricing and share unless Merck can demonstrate clear clinical or delivery differentiation.

From a financial perspective, a prolonged failure to ramp new assets would increase reliance on cash reserves and could force tougher tradeoffs between dividend growth, M&A, and R&D intensity. Investors should watch three proximate triggers: pivotal clinical readouts for ADC and KRAS programs, FDA actions on the subcutaneous Keytruda formulation, and the company’s pace of delivering the targeted cost savings.

What This Means For Investors#

Merck’s FY2024 performance restored a favorable financial starting point: robust free cash flow, lower net leverage, and improved margins. Those elements materially increase the probability that the company can both sustain its dividend and fund the multi-year transition required by Keytruda’s 2028 inflection. The path forward is not a single event but a sequence of clinical, commercial, and operational milestones that must align over multiple years.

Practically, investors should view Merck as a company with strong near-term cash generation and a deliberate strategic playbook: lifecycle management of Keytruda, a heavy R&D and launch pipeline focused on oncology and cardiovascular therapeutics, targeted acquisitions to broaden franchises, and cost programs to smooth earnings volatility. The balance sheet gives room for selective spending, but outcomes hinge on execution across the timeline to 2028 and beyond.

Finally, market valuation reflects these dynamics: trailing and forward P/E multiples in the low‑teens are consistent with a large-cap pharma trading at a modest premium for durable cash generation but with a discount for product‑concentration risk. Investors will be buying exposure to a company executing a multi-year transition with both measurable strengths and identifiable execution risks.

Key Takeaways#

Merck re-established robust profitability and cash flow in FY2024—$17.12B net income and $18.10B free cash flow—which materially improves near-term financial flexibility. The company faces a time-bound strategic challenge tied to Keytruda’s 2028 exclusivity and pricing risks, and management’s response is a mix of lifecycle defense, pipeline commercialization, cost savings (~$3.0B by 2027), and selective M&A. Balance-sheet metrics (net debt/EBITDA roughly 0.9–1.0x on FY figures) support continued dividends and targeted strategic spending, but the outcome depends on successful clinical readouts, regulatory approvals (including subcutaneous Keytruda), and realized cost savings.

Conclusion: From Rebound to Transition—Execution Is the Determinant#

Merck begins the multi‑year transition from a position of financial strength after FY2024’s rebound. The company has both the capital resources and a credible strategic playbook to navigate the Keytruda 2028 challenge, but the path is narrow: timing of approvals, pipeline commercialization success, competitive dynamics, and delivery of operational savings will jointly determine whether the company converts current cash‑flow strength into a diversified, durable growth profile. For stakeholders, the immediate story is one of restored flexibility; the medium‑term story is entirely execution dependent.
