Exhibit 99.1

For Immediate Release

SPAR Group, Inc. Reports First Quarter Fiscal 2026 Results

Higher Gross Margins Reflect Strategic Shift to Recurring Merchandising Revenue

Company Reiterates Full-Year Financial Guidance

CHARLOTTE, NC, May 12, 2026 – SPAR Group, Inc. (NASDAQ: SGRP) (“SGRP”, and together with its subsidiaries, “SPAR,” “SPAR Group” or the “Company”), an innovative services company offering comprehensive merchandising and marketing solutions for retailers and brands throughout the United States and Canada, today reported financial results for the period ended March 31, 2026.

William Linnane, President and Chief Executive Officer of SPAR Group, commented, “I am pleased to report that SPAR returned to positive EBITDA and delivered substantially higher gross margins than the prior year. Though revenue was down year-on-year, driven by a decline in our US Remodel business, we were pleased to see growth in our higher margin US merchandising business, and our Canada business. In the first quarter, we accomplished the following milestones:

"We have intentionally redesigned our go-to-market strategy to prioritize higher-margin core merchandising. Our partnership with ReposiTrak — combining proprietary technology with our flexible workforce platform to enhance inventory accuracy, reduce out-of-stocks, and improve on-shelf sales — is a strong example of our intent to generate durable, recurring revenue by delivering measurable value to our retail and consumer brand partners. I also believe there are meaningful opportunities to further reduce expenses as we continue to implement efficiencies across the business.”

“Our financial strategy is clear – drive up gross margins, drive down SG&A, and grow top line via recurring revenue streams, all by relentlessly focusing on our core merchandising business. We have clear momentum, and I look forward to reporting further progress as the year unfolds.

"Finally, we were pleased to reach a settlement agreement this month with one of our original co-founders and former CEO, Robert G. Brown. This resolution closes an important chapter for the Company and allows us to move forward with full alignment, constructive engagement, and a singular focus on serving the best interests of our shareholders," concluded Linnane.

Steven Hennen, Chief Financial Officer of SPAR Group, commented, “We remain focused on building a sustainable business model anchored in revenue growth, margin expansion, and disciplined cost control. By maintaining a solid financial framework — particularly through prudent cash and working capital management — we believe we are well-positioned to support planned top-line growth in 2026. Although we delivered positive EBITDA in the quarter, our cash flow from operating activities was affected by higher accounts receivable associated with growth in our merchandising business. While Adjusted EBITDA declined year-over-year, from $1.5 million to $737 thousand, this reflects the intentional revenue mix transition away from lower-margin Remodel activity and a normalization of SG&A; we view the underlying margin trajectory as encouraging and remain on track with our full-year outlook.

Today, we are reiterating our full-year 2026 financial outlook:

We remain committed to prudent capital allocation, with a clear focus on supporting growth while maintaining a solid balance sheet,” concluded Hennen.

First Quarter 2026 Highlights

Reconciliation of GAAP to Non-GAAP Financial Measures

Non-GAAP net income attributable to SPAR Group and related per share amounts represents net income attributable to SPAR Group adjusted for the removal of a one-time positive adjustment. Adjusted EBITDA represents net income before, as applicable from time to time, (i) depreciation and amortization of long-lived assets, (ii) interest expense (iii) income tax expense, (iv) Board of Directors incremental compensation expense, (v) restructuring, (vi) impairment, (vii) nonrecurring legal settlement costs and associated legal expenses unrelated to the Company's core operations, (viii) and special items as determined by management. These metrics are supplemental measures of our operating performance that are neither required by, nor presented in accordance with, GAAP. These measures have limitations as analytical tools and should not be considered in isolation or as an alternative to performance measure derived in accordance with GAAP as an indicator of our operating performance. We present Adjusted net income attributable to SPAR Group and per share amounts, and Adjusted EBITDA because management uses these measures as key performance indicators, and we believe that securities analysts, investors and others use these measures to evaluate companies in our industry. Our calculation of these measures may not be comparable to similarly named measures reported by other companies. The following tables present a reconciliation of net income, the most directly comparable measure calculated in accordance with GAAP, to these measures for the periods presented:
