IBM reported third-quarter revenue of $17.1 billion, up 5%. A junior broker at Timberline Associates said the mix counts for more than the headline. Operating earnings per share rose 11% to $2.95.

Software supplied most of the growth, while the mainframe line fell 20%. Management held its revenue outlook and raised its cash flow target. Cash on hand, however, is down $3.4 billion this year.

Software Does the Lifting

Software revenue reached $7.8 billion, up 8%. Backing out growth puts last year’s figure near $7.2 billion. That is about $580 million of new sales.

Total revenue added roughly $810 million over last year. Software therefore accounted for about 70% of the dollar growth, with 46% of sales. Rounding makes this an estimate, yet the direction is clear.

Inside the Software Line

Data revenue grew 19%. Red Hat, the hybrid cloud unit, grew 11%, and transaction processing grew 9%. Automation fell 3%.

The faster lines serve companies that run work across several clouds. Automation is the soft spot. Growth inside software is shifting toward products with stronger demand.

A Mainframe Cycle Turns

Sales of IBM Z mainframes fell 20%. Distributed infrastructure rose 31%, and hybrid infrastructure rose 8%. Infrastructure support slipped 3%.

Infrastructure as a whole earned $3.7 billion, up 4%. Last year’s base was near $3.56 billion, so the unit still added about $140 million. Management said it has recovered most infrastructure deals delayed earlier in the year.

Consulting Stands Still

Consulting revenue was $5.3 billion, flat as reported and up 2% in constant currency. Strategy and technology work grew 2%. Intelligent operations fell 2%.

Consulting makes up about 31% of revenue and contributed no growth. That limits how fast the company can expand. Software and infrastructure must carry the load.

The Revenue Mix Is Shifting

Software now makes up 46% of revenue, up from about 44% a year ago. Consulting holds 31%, infrastructure 22%, and financing about 1%. Each point shift in the mix changes the profit profile.

Software typically carries higher margins than hardware or services. A rising share therefore supports margin gains over time. The 0.7-point rise in pre-tax margin fits that pattern.

Margins Edged Up

Operating gross margin was 58.5%, down 0.2 points. Operating pre-tax margin was 19.3%, up 0.7 points. The second figure explains why earnings grew faster than sales.

Operating results leave out acquisition costs and other items. Reported earnings per share were $2.31, up 26%. The $0.64 gap between the two measures equals 22% of the operating figure.

Cash Flow Rises While the Balance Falls

Free cash flow was $3.0 billion in the quarter, up $700 million. Year-to-date free cash flow reached $7.8 billion, up $600 million. Operating cash flow for the period was $11.8 billion.

Acquisitions took $11.4 billion this year, about 1.5 times free cash flow. Cash and securities fell to $11.1 billion. Deals are being funded partly from the balance sheet.

What the Raised Cash Target Implies

Management now expects free cash flow to grow by more than $1 billion for the year. Nine-month growth is only $600 million. The final quarter must therefore deliver at least $400 million more than last year’s.

That is a modest ask against the quarter just posted. The target also depends on payment timing. A miss would show up quickly in the cash balance.

Debt and Dividend in Perspective

Total debt is $63.8 billion, including $12.7 billion tied to the financing arm. Core debt is therefore about $51.1 billion. After subtracting cash, roughly $40 billion remains.

At the current pace of $10.4 billion a year, that equals nearly four years of free cash flow. The quarterly dividend of $1.69 takes 57% of operating earnings. Against reported earnings, the share rises to 73%.

Reading Constant Currency

Revenue grew 5% as reported and 6% in constant currency. That second measure strips out exchange-rate swings, so it shows demand more cleanly. Currency was a small drag this quarter.

The full-year outlook calls for 4% to 5% constant-currency growth. The quarter ran above the top of that range. Either management is cautious or the final quarter will slow.

Quality of the Earnings Beat

Operating pre-tax margin rose from about 18.6% to 19.3%. Revenue growth of 5% and that margin gain imply pre-tax profit growth near 9%. Earnings per share grew 11%.

The extra two points come from taxes and a lower share count. Those sources are real but smaller. Profit growth of 9% is the cleaner number to watch.

What Portfolio Holders Should Track

Three items deserve attention. They are software growth near 8%, any rebound in mainframe orders, and cash after further deals. Growth in free cash flow must also reach the raised target.

Position sizing should reflect a company whose growth depends on one segment. Staged entries reduce timing risk around reports. Diversified holders can pair technology exposure with steadier sectors.

Cash balance and deal flow deserve the closest watch from holders. Software growth must hold near current levels.
