Exhibit 99.1

Nimble Storage, Inc. Q2FY16 Shareholder Letter

Executive Summary

Major architectural shifts are continuing to disrupt the storage market resulting in significant year-over-year revenue declines for incumbent vendors in our industry. Against this backdrop, we believe that the Nimble Storage Adaptive Flash Platform offers the broadest approach to leveraging flash storage in the modern data center. There are two key principles on which our platform is founded:

We believe that we stand alone in our ability to address the entire market opportunity as Hybrid-Flash arrays and All-Flash arrays displace disk-only storage arrays over the next several years.

		To address this market opportunity, our go-to-market strategy has been focused on building a large, diverse and global customer base. We are systematically expanding our customer base across the mid-sized enterprise, large enterprise and cloud service provider segments of the market. We believe that a large, highly satisfied customer base will propel our long-term growth given that data growth drives repeat deployments by our customers.   Even as we pursue our long-term goal of storage market leadership, our financial strategy has been to balance growth with profitability – investing to drive sustained high growth over many years while demonstrating improved operating leverage and increased positive cash flow on a year-over-year basis.

Q2FY16 marked strong progress on all fronts:

Adaptive Flash Platform: The broadest approach to leveraging flash in the Enterprise

The breadth of our software architecture is evident in the pace at which we have been able to deliver innovation across the Adaptive Flash Platform. Our milestone innovations over the past 18 months have spanned scale-out clustering, the ability to have variable flash to disk ratios, Fibre Channel support, high-end platforms, and triple parity RAID, among others.

Underscoring the differentiation of our Adaptive Flash Platform, the Flash Memory Summit Awards Committee named Nimble a Best of Show winner in the “Most Innovative Flash Memory Technology” category. IT Professionals also recognized Nimble as the 2015 Innovation Leader for Hybrid HDD/SSD Array in IT Brand Pulse’s most recent brand leader survey.

During Q2, we fortified our proven track record of innovation and advanced the Adaptive Flash Platform with significant new enterprise-grade capabilities as part of Nimble OS 2.3 and as part of InfoSight:

We anticipate that the functionality introduced as part of Nimble OS 2.3 will further allow us to demonstrate a radically superior value proposition relative to legacy incumbent and emerging competitive offerings.

In the three quarters following the introduction of Fibre Channel support, we have had continued momentum with the addition of 110 Fibre Channel customers in Q2, 74 of which were “net new Nimble” customers. The mix between Fibre Channel and iSCSI expanded to 17% (versus 16% and 12% in the prior two quarters respectively after excluding protocol agnostic bookings). As we expected, the average deal size for Fibre Channel orders remains significantly above our overall average. As a result we have experienced a double-digit percentage increase in ASP’s for new customer orders compared to Q2FY15.

As customers seek to simplify the deployment of infrastructure, we have partnered with industry leaders to create SmartStack converged infrastructure solutions that are experiencing rapid adoption. During Q2FY16, we saw the number of SmartStack customers compared to Q2FY15 more than double, and increase more than 40% sequentially compared to Q1FY16. For example, one of the largest deals this quarter was a significant 2.5PB deployment at a major healthcare organization that selected our SmartStack solution over incumbent EMC and other leading hyper-convergence solutions.

•       Land and expand model fueling repeat bookings. One of our biggest differentiators is the level of resiliency and availability our products provide, the level of visibility that we have into our customers’ environments with InfoSight, and the consequent high level of proactive support we are able to deliver. Over 90% of support cases are proactively identified by InfoSight instead of from customers calling us. We continue to experience availability well ahead of five 9s across our rapidly expanding installed base.   Because of these differentiators, our highly satisfied customer base on average spends 2.6X of its spend in the twelve quarters following its initial purchase. Global 5000 enterprise and Cloud Service Provider customers triple their spend in the eight quarters following their initial purchase. This pattern of repeat purchases has resulted in sales to existing customers representing more than 46% of bookings over the last 12 months, even as we have added new customers at a record pace.

Financial Performance: Q2FY16 Financial Results

As a reminder, all results presented in this letter are on a non-GAAP basis except for revenue and the balance sheet. Non-GAAP results exclude the impact of stock-based compensation.

Q2FY16 Highlights

Q2FY16 was another quarter of strong financial execution for us. We achieved revenue of $80.1 million, above our guidance of $77 million to $79 million. Q2 revenue grew 49% from prior year. Excluding foreign currency fluctuations, revenue would have been $82.8 million representing a 54% increase over Q2FY15. Our gross margin reached another record high during Q2 and remained industry leading at 67.8%. Our operating loss was $7.2 million, better than our projected operating loss of $8.0 million to $9.0 million, primarily due to higher than expected revenue and gross margin. Q2 non-GAAP EPS was a loss of $0.10 per share, better than our guidance of $0.11 to $0.12 loss per share. Our Cash balance increased by $12.1 million during Q2 with positive Cash Flow from Operations of $14.9 million and positive Free Cash Flow of $9.0 million.

Support and service gross margin in Q2FY16 was at a record high 60.1%, up by 7.2 percentage points from 52.9% in Q2FY15. The expansion in support and service gross margin was driven by increased revenue from our larger base of customers and economies of scale from our support organization, enabled by the automation capabilities of InfoSight.

Non-GAAP Operating Expenses and Margin

Q2FY16 total operating expenses were $61.5 million or 77% of revenue compared to Q2 last year operating expenses of $47.0 million or 87% of revenue. We ended Q2FY16 with 975 employees on board, an increase of 71 during the quarter. We saw an improvement in overall operating expense leverage by 10 percentage points which was spread across all of our functional areas.

•    Research and development (R&D) spending in Q2FY16 was $17.9 million or 22% of revenue. Leverage improved by 3.2 percentage points compared to Q2FY15 when spending was $13.7 million or 26% of total revenue. Our long-term target for R&D spending is 11% to 13% of total revenue.   •    Sales and marketing (S&M) spending in Q2FY16 was $38.5 million or 48% of revenue. Leverage improved by 4 percentage points compared to Q2FY15 spending of $28.0 million or 52% of revenue. Our long-term target for S&M spending is 28% to 31% of total revenue.   •    General and administrative (G&A) spending in Q2FY16 was $5.1 million or 6% of revenue. Leverage improved by 3.4 percentage points compared to Q2FY15 spending of $5.3 million or 10% of revenue. Our long-term target for G&A spending is 5% to 6% of total revenue.

Our Q2FY16 operating loss was $7.2 million, better than our guidance for an operating loss of $8.0 million to $9.0 million, and better than our operating loss of $10.7 million in Q2FY15. Q2FY16 operating margin improved to negative 9% compared to negative 20% in Q2FY15, an improvement of 11 percentage points. Our operating margin improvement was due to mainly operating expense leverage as well as stronger gross margin compared to Q2FY15. Our Adjusted EBITDA was negative $3.9 million or negative 5% of revenue in Q2FY16 compared to negative $8.7 million or negative 16% of revenue in Q2FY15, also an 11 percentage point improvement.
Q2FY16 non-GAAP EPS was a loss of $0.10 per share on approximately 78.2 million weighted average basic and diluted shares outstanding compared to a loss of $0.15 per share in Q2FY15. This was better than our guidance for a loss of $0.11 to $0.12 per share.

ended Q2 with inventory of $13.7 million, an increase of 48% from Q2FY15, as we increased our service and demo inventory to support our fast growing installed base of customers and prospects. Days sales in inventory (DSI) were 48 days in Q2FY16, consistent with the prior quarter. Capex spend during Q2FY16 was $5.9 million, or 7% of revenue. For FY16, we expect our total capex spend to be approximately 7% to 9% of total revenue.

Q3FY16 Financial Outlook

Our financial guidance for Q3FY16 is as follows:

As discussed previously, we remain on track to achieve our goal of non-GAAP operating income break-even by the end of the current fiscal year.

Our financial objectives remain (1) driving strong revenue growth and increasing our market share by growing significantly above the level of overall industry growth, (2) maintaining industry leading gross margins and (3) steadily progressing towards our long term target financial model of 16%-20% operating margin by delivering sequential improvement in operating margin every year.

We want to thank our partners and customers once again for embracing us, our investors for their confidence in us, and our employees for their dedication and flawless execution.

Non-GAAP Financial Measures

To provide investors with additional information regarding our financial results, Nimble Storage has disclosed in this release non-GAAP financial measures that are not calculated in accordance with generally accepted accounting principles in the United States, or GAAP. The Company provides non-GAAP gross margin, non-GAAP operating margin, non-GAAP net loss, non-GAAP net loss per basic and diluted share, free cash flow and adjusted EBITDA. In computing many of these non-GAAP financial measures, the Company excludes the effects of stock-based compensation, which is a recurring expense for the Company. The Company has provided reconciliation below of non-GAAP financial measures to the most directly comparable GAAP financial measures.

The Company discloses these non-GAAP financial measures because they are key measures used by the Company’s management and board of directors to understand and evaluate operating performance and trends, to prepare and approve the annual budget and to develop short-term and long-term operational and compensation plans. In particular, the exclusion of certain expenses in calculating non-GAAP financial measures can provide a useful measure for period-to-period comparisons of the Company’s business. Accordingly, the Company believes that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating the Company’s operating results in the same manner as the Company’s management and board of directors.

Non-GAAP financial measures have limitations as analytical tools and, as such, should not be considered in isolation or as substitutes for analysis of the Company’s results as reported under GAAP. Some of these limitations are:
