Exhibit 99.1

SIGNET JEWELERS RAISES FIRST QUARTER AND FULL YEAR GUIDANCE

HAMILTON, Bermuda, April 12, 2021 – Signet Jewelers Limited ("Signet") (NYSE:SIG), the world's largest retailer of diamond jewelry, today is increasing its Fiscal 2022 first quarter and full year guidance.

Signet has seen stronger than expected conversion and average ticket values in the first quarter. The Company believes this topline strength is likely due to a combination of traction from strategic initiatives as well as tailwinds from stimulus, tax refunds and consumer enthusiasm on the heels of vaccine rollouts – particularly during the Company’s guest appreciation events in late March.

In addition, the Company has evaluated the impact of inventory delays related to recent COVID-19 surges in India and other parts of the world. At this time, Signet believes it has mitigated these short-term impacts; however, if the duration and magnitude of these inventory slowdowns intensify, there could be future negative impacts on the Company’s full year guidance.

Fiscal 2022 Guidance

	Updated Guidance		Guidance as of 3/18/21
	First Quarter	Full Year	First Quarter	Full Year
Total revenue (in billions)	$1.57 to $1.60	$6.00 to $6.14	$1.42 to $1.46	$5.85 to $6.00
Same store sales (1)	97% to 99%	17% to 20%	80% to 84%	14% to 17%
Non-GAAP operating income (in millions) (2)	$85 to $100	$335 to $364	$40 to $60	$290 to $324

(1) Same store sales include physical stores and eCommerce sales

(2) See description of non-GAAP measures below

Forecasted non-GAAP operating income provided above excludes potential non-recurring charges. However, given the potential impact of non-recurring charges to the GAAP operating income, we cannot provide forecasted GAAP operating income or the probable significance of such items without unreasonable efforts. As such, we do not present a reconciliation of forecasted non-GAAP operating income to corresponding GAAP operating income.

The Company is reiterating the following underlying assumptions supporting its Full Year Fiscal 2022 Guidance:

1.Signet expects stronger sales performance in the first half of the fiscal year. As the vaccine rollout progresses, there could be a shift of consumer discretionary spending away from the jewelry category toward experience-oriented categories, the magnitude and timing of which is difficult to predict. Further, Signet expects categories with pent up demand to be promotional in order to capture discretionary spend. As such, the Company is planning for increased marketing expenses to continue to fuel momentum in the front half as well as to proactively manage against shifts in consumer spending as the year progresses. While Signet’s transformational initiatives continue to gain traction, the Company is conservatively planning for same store sales to be negative in the second half of the fiscal year. Depending on the timing and extent of potential shifts in spending, future results could differ materially from current guidance.

2.The Company’s Inspiring Brilliance strategy requires additional investments in digital and technology to further strengthen our competitive advantage and long-term positioning within the jewelry category. To partially mitigate the increased level of investment, gross cost savings of $50 million - $75 million are expected in Fiscal 2022, with continued benefits from closed stores and operational efficiencies. Cost savings are expected to benefit both SG&A and gross margin.

3.Signet has planned Fiscal 2022 capital expenditures in the range of $150 million to $175 million, reflecting continued investments in technology and innovation. Recall that the Company reduced its capital expenditures in Fiscal 2021 to $83 million given the cash conservation focus in response to the pandemic.

4.The Company is planning to close over 100 stores in Fiscal 2022 and will open up to 100 locations, primarily in highly efficient kiosks.

5.Continued uncertainty surrounding multiple factors include the magnitude and potential resurgence of COVID-19 in key trade areas, extended duration of heightened unemployment, supply chain disruptions and macro or governmental influences on consumers’ ability to spend, particularly in discretionary categories like jewelry. Further, there can be no assurance that preliminary quarter to date trends will continue for the remainder of the first quarter and are not indicative of future performance. Please see disclosures within the Safe Harbor Statement for other risk factors.

Non-GAAP Measures

In addition to financial measures calculated and presented in accordance with accounting principles generally accepted in the US (“GAAP”), the Company believes that non-GAAP financial measures, when reviewed in conjunction with GAAP financial measures, can provide more information to assist investors in evaluating historical trends and current period performance. For these reasons, internal management reporting and the Company’s guidance includes non-GAAP measures. Items may be excluded from GAAP financial measures when the Company believes this provides useful supplementary information to management and investors in assessing the operating performance of our business.

These non-GAAP financial measures should be considered in addition to, and not superior to or as a substitute for the GAAP financial measures presented in the Company’s consolidated financial statements and other publicly filed reports. In addition, our non-GAAP financial measures may not be the same as or comparable to similar non-GAAP measures presented by other companies.
