Gilead Sciences (GILD)

Biopharmaceutical company Gilead Sciences (NASDAQ:GILD) announced better-than-expected revenue in Q4 CY2025, with sales up 5.2% year on year to $7.93 billion. On the other hand, the company’s full-year revenue guidance of $29.8 billion at the midpoint came in 1.2% below analysts’ estimates. Its non-GAAP profit of $1.86 per share was 1.9% above analysts’ consensus estimates.

Company Overview

From its groundbreaking work in developing the first single-tablet regimens for HIV treatment, Gilead Sciences (NASDAQ:GILD) develops and markets innovative medicines for life-threatening diseases including HIV, viral hepatitis, COVID-19, and cancer.

Over the next few years, therapeutic companies, which develop a wide variety of treatments for diseases and disorders, face strong tailwinds from advancements in precision medicine (including the use of AI to improve hit rates) and growing demand for treatments targeting rare diseases. However, headwinds such as rising scrutiny over drug pricing, regulatory unknowns, and competition from larger, more resourced pharmaceutical companies could weigh on growth.

Gilead's competitors include major pharmaceutical companies such as Merck (NYSE:MRK), Johnson & Johnson (NYSE:JNJ), and GlaxoSmithKline (NYSE:GSK) in the HIV space; AbbVie (NYSE:ABBV) in hepatitis C; and Bristol Myers Squibb (NYSE:BMY), Novartis (NYSE:NVS), and Roche (OTCQX:RHHBY) in oncology.

Larger companies benefit from economies of scale, where fixed costs like infrastructure, technology, and administration are spread over a higher volume of goods or services, reducing the cost per unit. Scale can also lead to bargaining power with suppliers, greater brand recognition, and more investment firepower. A virtuous cycle can ensue if a scaled company plays its cards right.

With $29.39 billion in revenue over the past 12 months, Gilead Sciences sports economies of scale. This is important as it gives the company more leverage in a heavily regulated, competitive environment that is complex and resource-intensive.

A company’s long-term sales performance can indicate its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Over the last five years, Gilead Sciences grew its sales at a tepid 3.9% compounded annual growth rate. This was below our standard for the healthcare sector and is a rough starting point for our analysis.

We at StockStory place the most emphasis on long-term growth, but within healthcare, a half-decade historical view may miss recent innovations or disruptive industry trends. Gilead Sciences’s annualized revenue growth of 4.6% over the last two years aligns with its five-year trend, suggesting its demand was consistently weak.

We can better understand the company’s revenue dynamics by analyzing its most important segment, HIV. Over the last two years, Gilead Sciences’s HIV revenue was flat. This segment has lagged the company’s overall sales.

This quarter, Gilead Sciences reported year-on-year revenue growth of 5.2%, and its $7.93 billion of revenue exceeded Wall Street’s estimates by 3.2%.

Looking ahead, sell-side analysts expect revenue to grow 2.8% over the next 12 months, a slight deceleration versus the last two years. This projection is underwhelming and implies its products and services will see some demand headwinds.

Gilead Sciences has been a well-oiled machine over the last five years. It demonstrated elite profitability for a healthcare business, boasting an average adjusted operating margin of 40.8%.

Analyzing the trend in its profitability, Gilead Sciences’s adjusted operating margin decreased by 1.1 percentage points over the last five years, but it rose by 5.9 percentage points on a two-year basis. Still, shareholders will want to see Gilead Sciences become more profitable in the future.

In Q4, Gilead Sciences generated an adjusted operating margin profit margin of 39%, down 2.4 percentage points year on year. This contraction shows it was less efficient because its expenses grew faster than its revenue.

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

Gilead Sciences’s unimpressive 2.8% annual EPS growth over the last five years aligns with its revenue performance. This tells us it maintained its per-share profitability as it expanded.

In Q4, Gilead Sciences reported adjusted EPS of $1.86, down from $1.90 in the same quarter last year. Despite falling year on year, this print beat analysts’ estimates by 1.9%. Over the next 12 months, Wall Street expects Gilead Sciences’s full-year EPS of $8.15 to grow 7.6%.

Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.

Gilead Sciences has shown terrific cash profitability, enabling it to reinvest, return capital to investors, and stay ahead of the competition while maintaining an ample cushion. The company’s free cash flow margin was among the best in the healthcare sector, averaging an eye-popping 33.2% over the last five years.

Taking a step back, we can see that Gilead Sciences’s margin dropped by 7.4 percentage points during that time. If its declines continue, it could signal increasing investment needs and capital intensity.

Gilead Sciences’s free cash flow clocked in at $3.12 billion in Q4, equivalent to a 39.4% margin. This result was good as its margin was 1.8 percentage points higher than in the same quarter last year, but we wouldn’t put too much weight on the short term because investment needs can be seasonal, causing temporary swings. Long-term trends trump fluctuations.

EPS and free cash flow tell us whether a company was profitable while growing its revenue. But was it capital-efficient? Enter ROIC, a metric showing how much operating profit a company generates relative to the money it has raised (debt and equity).

Although Gilead Sciences hasn’t been the highest-quality company lately, it historically found a few growth initiatives that worked out well. Its five-year average ROIC was 15.1%, impressive for a healthcare business.

We like to invest in businesses with high returns, but the trend in a company’s ROIC is what often surprises the market and moves the stock price. Over the last few years, Gilead Sciences’s ROIC averaged 2.2 percentage point decreases each year. We like what management has done in the past, but its declining returns are perhaps a symptom of fewer profitable growth opportunities.

We enjoyed seeing Gilead Sciences beat analysts’ revenue expectations this quarter. On the other hand, its full-year EPS guidance slightly missed and its full-year revenue guidance fell slightly short of Wall Street’s estimates. Overall, this quarter could have been better. The stock traded down 2.9% to $143.01 immediately following the results.

When considering an investment in Gilead Sciences, investors should account for its valuation and business qualities as well as what’s happened in the latest quarter.

Gilead Sciences has a few positive attributes, but it doesn’t top our wishlist. Although its revenue growth was uninspiring over the last five years and analysts expect growth to slow over the next 12 months, its powerful free cash flow generation enables it to stay ahead of the competition through consistent reinvestment of profits. We advise investors to be cautious with this one, however, as its cash profitability fell over the last five years.

Gilead Sciences’s P/E ratio based on the next 12 months is 17.3x. This valuation is reasonable, but the company’s shakier fundamentals present too much downside risk. We're pretty confident there are superior stocks to buy right now.

Wall Street analysts have a consensus one-year price target of $139.24 on the company (compared to the current share price of $145.81).
