Exhibit 99.1

Nimble Storage, Inc. Q1FY16 Shareholder Letter

Executive Summary

The storage industry, comprising $40B in storage systems and software, is going through a period of unprecedented change driven by the disruptive impact of flash. Specifically, the external storage systems market that was comprised entirely of disk arrays a few years ago is seeing a rapid decline in disk-only storage arrays as two other segments are gaining share:

We designed our Adaptive Flash Platform, consisting of our flash-optimized file system and our Infosight cloud-based management software, with the goal of addressing the entire spectrum of workloads across the Enterprise. We believe our Adaptive Flash arrays have the ability to deliver the performance of all-flash arrays and address multi-petabyte deployments far more cost-effectively than products from legacy competitors and emerging competitors. As customers aim to simultaneously consolidate storage while delivering different service levels for hundreds or even thousands of applications, we believe that we stand alone in being able to span the entire spectrum of needs of Enterprise customers among next-generation flash-optimized storage platforms.

In Q1FY16 we executed very well against that growth opportunity:

During Q1FY16, our bookings from large deals grew at a rapid pace. Deals over $100K grew at 142% compared to Q1FY15 and represented 45% of our total bookings. Similarly, bookings from deals over $250K more than quadrupled during the quarter driven by wins among large enterprises.

Rapid growth in Global 5000 Enterprises and Cloud Service Providers

Over the last two years, we made several investments in broadening our product portfolio with enterprise-centric features such as

scale-out functionality, adaptive flash capabilities and Fibre Channel functionality. We have also been systematically expanding our enterprise-focused sales teams in conjunction with expanding our technology platform.   These investments have resulted in strong growth in our

bookings from Global 5000 enterprises, which more than doubled from a year ago. Moreover, we now count dozens of Global 500 companies as our customers, and our solutions are increasingly being deployed in larger and more critical environments with escalating requirements. In a similar vein, we are seeing continued growth in our cloud service provider customer base where bookings have also more than doubled from a year ago.

Some key customer wins during Q1FY16 included the following:

Land and expand model is driving repeat bookings

One of our most powerful areas of differentiation is the consistently high level of customer satisfaction within our installed base, which in turn drives a consistently strong pattern of repeat deployments. Our compelling product value proposition is a key contributor to driving repeat deployments. An equally significant and unique aspect of

our approach is the value proposition delivered by InfoSight: proactively monitoring deployments to identify bottlenecks and preempt issues, helping to accurately plan and forecast for future storage performance and capacity needs, and rapidly resolving issues when they occur.

Across our entire customer base of over 5,500 customers, a customer on average more than doubles its initial spend over a 2-year time frame after the initial purchase. When we look at our Global 5000 customers and our cloud service provider customers, we believe the propensity for repeat deployment is even greater. This pattern of repeat deployments by our customers has resulted in repeat bookings accounting for a record 51% of our overall bookings in Q1FY16.

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

Our Adaptive Flash Platform is based on two foundational innovations – our CASL file system software and our InfoSight cloud-based management software. Over the last few years, we have delivered innovation at a rapid pace that has enabled us to span the broadest spectrum of workloads across the Enterprise - ranging from extremely demanding, performance-intensive workloads to Petabyte-scale capacity-intensive workloads.

Q1FY16 Highlights

Q1FY16 Financial Results   Q1FY16 was a very strong financial quarter for us. We achieved revenue of $71.3 million, above our guidance of $68 million to $70 million. Q1 revenue grew 53% from prior year. Excluding fluctuations in foreign currency, revenue would have been $73.4M representing a 58% increase over Q1FY15. Our gross margin reached a record high during Q1 and remained industry leading at 67.6%. Our operating loss was $7.9 million, better than our projected operating loss of $9.0 million to $10.0 million, primarily due to higher than expected revenue and gross margin. Q1 non-GAAP EPS was a loss of $0.10 per share, better than our guidance of $0.13 to $0.14 loss per share.

Gross margin was 67.6% in Q1FY16, a record high for us, and an improvement of 1.4 percentage points compared to Q1FY15. Product gross margin in Q1FY16 was 69.1%, an improvement of 10 basis points compared to Q1FY15. Our industry leading product gross margin continues to reflect the efficiencies of our Adaptive Flash platform.   Support and service gross margin in Q1FY16 was at a record high 59.5%, up by 14.7 percentage points from 44.8% in Q1FY15. The expansion in support and service gross margin continues to be 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.

Q1FY16 total operating expenses were $56.1 million or 79% of revenue compared to Q1 last year operating expenses of $40.9 million or 88% of revenue. We saw an improvement in overall operating expense leverage by 9 percentage points which was spread across all of our functional areas.

•    Research and development (R&D) spending in Q1FY16 was $16.3 million or 23% of revenue. Leverage improved by 2.5 percentage points compared to Q1FY15 when spending was $11.8 million or 25% 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 Q1FY16 was $34.3 million or 48% of revenue. Leverage improved by 4 percentage points compared to Q1FY15 spending of $24.3 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 Q1FY16 was $5.5 million or 8% of revenue. Leverage improved by 2.7 percentage points compared to Q1FY15 spending of $4.9 million or 10% of revenue. Our long-term target for G&A spending is 5% to 6% of total revenue.

Our Q1FY16 operating loss was $7.9 million, better than our guidance for an operating loss of $9.0 million to $10.0 million, and better than our operating loss of $10.1 million in Q1FY15. Q1FY16 operating margin improved to negative 11% compared to negative 22% in Q1FY15, an improvement of 11 percentage points. Our Adjusted EBITDA was negative $4.5 million or negative 6% of revenue in Q1FY16 compared to negative $8.1 million or negative 17% of revenue in Q1FY15, also an 11 percentage point improvement.

Q1FY16 non-GAAP EPS was a loss of $0.10 per share on approximately 76.5 million weighted average basic and diluted shares outstanding compared to a loss of $0.14 per share in Q1FY15. This was better than our guidance for a loss of $0.13 to $0.14 per share.

We ended Q1FY16 with cash and cash equivalents of $201.5 million. As we expected, during Q1, our cash balance decreased by $6.9 million primarily due to the timing of payout of accrued compensation from our last fiscal year end, and the linearity of our billings during the quarter. As previously discussed, we estimate that our cash flow will be positive for the entire fiscal year with an overall increase in our cash balance by year-end.   In Q1FY16, we achieved a cash conversion cycle of 13 days, ahead of our target of 20 days. We ended Q1 with accounts receivables of $44.3 million, an increase of $9.0 million from Q4FY15. Days sales outstanding (DSO) were 43 days, inside of our target range of 35 to 45 days and was consistent with our Q3 DSO level. DSO increased by 4 days from Q4FY15 (a quarter which had better billings linearity due to December, the calendar year end for many companies, and January, our own fiscal year end). We ended Q1 with inventory of $12.9 million, an increase of $0.9 million from Q4FY15. Days sales in inventory (DSI) were 48 days, above our target range of 35 to 45 days, as we increased our service and demo inventory to support our fast growing installed base of customers and prospects.

Capex spend during Q1FY16 was $8.1 million, or 11% of revenue, mainly due to leasehold improvements and R&D lab investments. For FY16, we expect our total capex spend to be approximately 7% to 9% of total revenue.

Q2FY16 Financial Outlook

Our financial guidance for Q2FY16 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:
