MD&A
Text added vs the prior filing · source: 10-Q · 2026-09-03
During the third quarter of fiscal 2026, we completed a convertible note offering of $2.9 billion and immediately used the proceeds to repay our term loan as described in Note 13 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
Our capital allocation strategy is focused on maintaining our significant innovation investment, investing in select transactions, and returning value to stockholders, while preserving our strategic and operational flexibility.

•Significant asset impairments and restructuring costs decreased by $2.1 million primarily related to higher facilities restructuring costs in fiscal 2025.
•Interest and other income, net increased by $7.3 million, primarily resulting from higher interest income on our investments.

•Services gross margin decreased by 260 basis points, primarily due to a less favorable services mix, partially offset by improved margins on implementation services.
•Significant asset impairments and restructuring costs remained relatively unchanged.
•Interest and other income, net increased by $6.2 million, primarily reflecting the impact of foreign exchange rates on assets and liabilities denominated in a currency other than the relevant functional currency, net of hedging activity.

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
