TESSCO Special Committee Responds to Recent Comments by Robert B. Barnhill, Jr.

HUNT VALLEY, Md. — November 11, 2020 – TESSCO Technologies Incorporated (NASDAQ: TESS), a leading value-added distributor and solutions provider for the wireless industry, today issued the following statement on behalf of the Special Committee of the Board of Directors in response to recent comments made by Robert B. Barnhill, Jr.:

Mr. Barnhill’s complaint in his most recent press release is another in a long line of manufactured issues.

On October 20, 2020, TESSCO’s Board unanimously approved an agreement that would result in its exit from the Retail Business. The agreement was executed on October 28, 2020 and TESSCO made the agreement public the following week, months in advance of any requirement to do so.

Mr. Barnhill, who supported and voted in favor of the transaction, is disingenuous when he claims the agreement discourages board change. The agreement merely provides that if TESSCO experiences a change of control and then purposefully breaches the agreement or frustrates the closing of the deal, TESSCO must return the buyer’s $1 million purchase price deposit, reimburse the buyer’s expenses (up to $500,000) and pay a specific amount of damages ($500,000). That is not a “proxy put” as Mr. Barnhill claims – it is a liquidated damages clause that any reasonable buyer would insist upon to ensure that any new board will perform the Company’s obligations under the agreement.

It should surprise no one that Mr. Barnhill’s consent solicitation has unnerved some of TESSCO’s stakeholders and counterparties. In ways large and small – including with respect to the exit of the Retail Business – Mr. Barnhill’s campaign has slowed and interfered with TESSCO’s transformation.

The existing Board intends to perform its obligations under the agreement. Given that Mr. Barnhill supported the transaction and voted in favor of the agreement, we expect he and his nominees would proceed to close if they are elected. Accordingly, there is no reason to believe that this liquidated damages provision will ever be triggered.

Mr. Barnhill’s most recent complaint, like so many of his others, is an attempt to deceive shareholders and is simply manufactured to justify his desire for excessive influence over the TESSCO Board.

With three exceptional new directors added to the Board in the last five months, and three directors departing the Board, Mr. Barnhill’s cry of entrenchment rings hollow. The time has come for Mr. Barnhill to accept that there has already been substantial change at TESSCO.

The Board calls upon Mr. Barnhill to drop his campaign and allow TESSCO to get to work.

TESSCO shareholders are reminded that their vote is important, no matter how many or how few shares they own. TESSCO urges you to support your Company’s Board by signing, dating and returning the enclosed GREEN Consent Revocation Card TODAY. If you receive a White Consent Card from Robert B. Barnhill, Jr., please disregard it.

If you have any questions or need assistance executing your revocation,

please contact TESSCO’s proxy solicitor,

Forward-Looking Statements

This release contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical facts contained herein, including statements regarding our future results of operations and financial position, strategy and plans and future prospects, and our expectations for future operations, are forward-looking statements. These forward-looking statements are based on current expectations and analysis, and actual results may differ materially from those projected. These forward-looking statements may generally be identified by the use of the words “may,” “will,” “expects,” “anticipates,” “targets,” “goals,” “projects,” “intends,” “plans,” “seeks,” “believes,” “estimates,” and similar expressions, but the absence of these words or phrases does not necessarily mean that a statement is not forward-looking. These forward-looking statements are only predictions and involve a number of risks, uncertainties and assumptions, many of which are outside of our control. Our actual results may differ materially and adversely from those described in or contemplated by any such forward-looking statement for a variety of reasons, including those risks identified in our most recent Annual Report on Form 10-K and other periodic reports filed with the Securities and Exchange Commission (the “SEC”), under the heading “Risk Factors” and otherwise. Consequently, the reader is cautioned to consider all forward-looking statements in light of the risks to which they are subject. For additional information with respect to risks and other factors which could occur, see Tessco’s Annual Report on Form 10-K for the year ended March 29, 2020, including Part I, Item 1A, “Risk Factors” therein, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other securities filings with the SEC that are available at the SEC’s website at www.sec.gov and other securities regulators.

We are not able to identify or control all circumstances that could occur in the future that may materially and adversely affect our business and operating results. Without limiting the risks that we describe in our periodic reports and elsewhere, among the risks that could lead to a materially adverse impact on our business or operating results are the following: the impact and results of the consent solicitation and other activism activities by Robert B. Barnhill, Jr. and certain other participants in his consent solicitation and/or other activist investors, termination or non-renewal of limited duration agreements or arrangements with our vendors and affinity partners that are typically terminable by either party upon several months or otherwise relatively short notice; loss of significant customers or relationships, including affinity relationships; loss of customers either directly or indirectly as a result of consolidation among large wireless services carriers and others within the wireless communications industry; the strength of our customers’, vendors’ and affinity partners’ business; negative or adverse economic conditions, including those adversely affecting consumer confidence or consumer or business spending or otherwise adversely impacting our vendors or customers, including their access to capital or liquidity, or our customers’ demand for, or ability to fund or pay for, the purchase of our products and services; our dependence on a relatively small number of suppliers and vendors, which could hamper our ability to maintain appropriate inventory levels and meet customer demand; changes in customer and product mix that affect gross margin; effect of “conflict minerals” regulations on the supply and cost of certain of our products; failure of our information technology system or distribution system; system security or data protection breaches; technology changes in the wireless communications industry or technological failures, which could lead to significant inventory obsolescence and/or our inability to offer key products that our customers demand; third-party freight carrier interruption; increased competition from competitors, including manufacturers or national and regional distributors of the products we sell and the absence of significant barriers to entry which could result in pricing and other pressures on profitability and market share; our relative bargaining power and inability to negotiate favorable terms with our vendors and customers; our inability to access capital and obtain financing as and when needed; transitional and other risks associated with acquisitions of companies that we may undertake in an effort to expand our business; claims against us for breach of the intellectual property rights of third parties; product liability claims; our inability to protect certain intellectual property, including systems and technologies on which we rely; our inability to hire or retain for any reason our key professionals, management and staff; health epidemics or pandemics or other outbreaks or events, or national or world events or disasters beyond our control; and the possibility that, for unforeseen or other reasons, we may be delayed in entering into or performing, or may fail to enter into or perform, anticipated contracts or may otherwise be delayed in realizing or fail to realize anticipated revenues or anticipated savings.

4 Executive Summary

5 Executive Summary TESSCO’s transformation is well underway TESSCO is well positioned to capture explosive industry growth ▪ TESSCO has a leadership position in the wireless industry, supplying value - added resellers, carriers and private network operators with state - of - the - art equipment from hundreds of manufacturers ▪ The wireless industry is experiencing once - in - a - generation technology deployments for 5G, increased spending on Private LTE and CBRS, rapidly growing Wi - Fi 6 chipsets shipment, and massive growth in Internet - of - Things (IoT) devices ▪ Strong execution now is critical ▪ TESSCO is now being transformed by a new management team and strategy that is focused on value - added distribution, proprietary Ventev products and expanded services and solutions ▪ TESSCO is also fixing a variety of operational issues that have plagued the Company since Mr. Barnhill’s time in leadership, including antiquated IT systems, operational inefficiencies and suboptimal sales force organization ▪ After a year - long process, recently signed an agreement¹ to divest its Retail Business segment to focus on higher - margin commercial products and improve overall customer mix profile TESSCO has the right leadership team in place and a substantially refreshed Board of Directors ▪ The Board unanimously hired Sandip Mukerjee as TESSCO’s new CEO in August 2019; he has been making significant strides ▪ TESSCO’s executive team has also been largely refreshed since 2019 ▪ The Board has engaged extensively with shareholders and has conducted a thorough search for new directors, adding three directors since July 2020 ▪ Since 2018, the Board has added five new directors; three directors have or will have retired by year end ▪ With these substantive changes to the Board and management team, it is important to maintain an adequate level of institutional knowledge 1 On October 29, 2020, TESSCO entered into an agreement which, if completed, will result in the exit from its Retail Business. Th e transaction is expected to close at the end of November 2020.

6 Executive Summary, Continued Mr. Barnhill’s Consent Solicitation appears to be aimed at restoring Mr. Barnhill’s influence ▪ At the depths of the COVID - 19 crisis (with TESSCO’s stock down significantly), Mr. Barnhill said he was interested in taking TESSCO private ▪ The Board set up a Special Committee to review Mr. Barnhill’s interest and to ensure a full and fair sale process ▪ Mr. Barnhill appeared to be frustrated with the proposed process and withheld his votes from the members of the Special Committee at the 2020 meeting ▪ Following his unsuccessful “withhold” campaign, Mr. Barnhill quickly launched a consent solicitation to replace a majority of the Board ▪ Mr. Barnhill’s ultimate goal appears to be having a TESSCO Board that will answer to him ▪ Mr. Barnhill’s criticisms are ironic – they reflect more on his own legacy and operational failures than the actions of the current management team or refreshed Board ▪ The Board hired a new CEO and fully supported a new plan to resolve these issues; Mr. Barnhill has been enthusiastic in private communications about the current team, strategies and performance ▪ Mr. Barnhill’s “ideas” for improvement are largely gleaned from management’s comprehensive plan ▪ Mr. Barnhill’s nominees have refused to allow our Nominating and Governance Committee to interview them, but do not appear to possess needed or additive experience or skills Mr. Barnhill’s criticisms are disingenuous, and his “plan” parrots the current strategy Mr. Barnhill is having second thoughts about his transition out of the Board and Company after 25 years ▪ Mr. Barnhill held senior executive positions, as CEO or Executive Chairman, for 24 years beginning in 1994; he remains a director ▪ Especially during Mr. Barnhill’s last years as CEO, TESSCO dramatically underperformed the market and was beset by strategy and operational issues ▪ Nevertheless, Mr. Barnhill received more than $40 million from TESSCO from 1994 to 2020 ▪ With Mr. Barnhill’s consent, he stepped down from the Executive Chairman role; he also supported the implementation of a mandatory Board retirement age of 76 ▪ In 2019, we believe Mr. Barnhill became disaffected with certain directors when they refused to replace the then - CEO with Mr. Barnhill’s hand - picked candidate, John Diercksen ; Mr. Barnhill withheld his votes from those directors in 2019

12 Barnhill’s Campaign Is Driven by Self - Interest ▪ In 2019, Mr. Barnhill’s hand - picked candidate for CEO was rejected by the Board ▪ Mr. Barnhill’s income has been reduced significantly: - He is no longer collecting an executive salary and bonus at TESSCO - In 2021, he will be past the age limit for Board membership - Due to COVID - 19 and ongoing turnaround efforts, TESSCO’s dividend payments have been suspended for the foreseeable future ▪ Faced with uncertainty about his own future at TESSCO and his diminishing influence, Mr. Barnhill announced his intention to pursue a buyout of the Company - The Board formed a Special Committee to examine Barnhill’s proposal - The Special Committee sought a reasonable non - disclosure agreement to enable Mr. Barnhill to begin the evaluation process, which he rejected - Mr. Barnhill ultimately did not make a formal acquisition offer ▪ After the Board insisted on a fair process, Mr. Barnhill has launched a consent solicitation to ensure the Board is filled with his hand - picked directors Source: FactSet and company filings.

We believe that the nature and timing of Barnhill’s campaign is motivated by his desire to have a Board of Directors beholden to him

14 Robust Response to 2020 Shareholder Vote ▪ The Board nominated, and shareholders elected, Stephanie Dismore to the Board at the 2020 annual meeting in late July, replacing one legacy TESSCO director ▪ Hired Spencer Stuart to conduct additional director searches to add new skills and further diversity to the Board ▪ Sought to interview Mr. Barnhill’s recommended candidates, but they refused to be interviewed as part of our process ▪ Added two new directors in November 2020 after a thorough search evaluating dozens of potential candidates ▪ One legacy director retired, with another committed to retire following the consent solicitation process , even if Mr. Barnhill’s efforts are unsuccessful The Board announced a Board evolution process in April 2020 and accelerated its process following the 2020 Annual Meeting and after thorough engagement with our public shareholders

15 Despite Numerous Attempts, Mr. Barnhill Has Refused to Resolve This Matter Reasonably We believe Mr. Barnhill is seeking to replace a majority of the Board with his hand - picked candidates to enhance his otherwise diminishing influence ▪ Mr. Barnhill was unable to convince the Board to hire Mr. Diercksen as CEO in early 2019 ▪ Mr. Barnhill had numerous disagreements in 2019 and 2020 with the Board Mr. Barnhill then approached the Company with the intention to take it private; the Board engaged ▪ The Board formed a Special Committee to independently negotiate with Mr. Barnhill ▪ Mr. Barnhill refused to sign a reasonable non - disclosure agreement and instead sought to engage directly with employees, seeking information ▪ After bristling at the process set by the Special Committee, Mr. Barnhill announced his intention to withhold his votes at our July 2020 Annual Meeting from the independent directors who served on the Special Committee When Mr. Barnhill then announced this consent solicitation, the Special Committee again sought to engage in good faith to reach an amicable resolution of the consent solicitation ▪ The Special Committee offered to waive (again) the age limit for directors and agree that Mr. Barnhill would be re - nominated in 2021 and 2022 and to seat one of his nominees ▪ Mr. Barnhill rejected that offer, and his only counter - offer was to have four of six independent directors resign and to insist on the appointment of all his nominees The Nominating and Governance Committee has also sought to include Mr. Barnhill’s nominees in the Board refreshment process ▪ Mr. Barnhill rejected the Committee’s request to interview his candidates multiple times ▪ The Committee also contacted the candidates individually; they responded collectively and refused to sit for interviews unless the Committee first agreed to a “settlement framework” with Mr. Barnhill ▪ The Committee would be violating its duties by putting Barnhill’s nominees on the Board without proper vetting, and has continued to seek access to Mr. Barnhill’s nominees to interview them 1 2 3 4 Source: Company emails and filings

16 Why Shareholders Should Support TESSCO’s Board ▪ TESSCO is well positioned as a value - added distributor in the growing wireless infrastructure market ▪ TESSCO has the right strategic plan , developed by our new CEO, with strong support from the new Chairman, in conjunction with (and with the unanimous approval of) the Board ▪ We are making significant progress correcting legacy operating issues , such as modernizing our technology infrastructure, and expect to profitably grow over the next few years ▪ Mr. Barnhill’s campaign is disingenuous: he appears to be seeking a return to his prior glory days with excessive influence ‒ Mr. Barnhill’s operating track record was disappointing and TESSCO significantly lagged in TSR during his tenure ‒ Mr. Barnhill is not offering any new strategies or operating plan ▪ Mr. Barnhill’s nominees do not add value and, if elected, could jeopardize TESSCO’s operating momentum and stability ‒ The Special Committee believes it would be a mistake to change course now, when the current plan appears to be succeeding The Board urges shareholders to support the refreshed Board and the Company’s current strategic plan by rejecting Mr. Barnhill’s consent solicitation campaign ▪ Our Board has taken proactive steps to course - correct when necessary ‒ Hired Sandip Mukerjee as CEO in August 2019 ‒ Entered into an agreement to exit Retail Business in October 2020 ▪ Our Board has been substantially refreshed with five new directors added since 2018, including three in 2020 alone ‒ Three directors have retired since 2018, with a fourth committed to retiring after the consent solicitation ‒ Our directors have complementary skills, extensive experience and important institutional knowledge needed for a well - balanced Board Source: Company filings and emails

For the past 2 hours I have reviewed your Path Forward plan - it is outstanding.”

24 LEGACY ▪ TESSCO’s strategy under Mr. Barnhill’s leadership focused heavily on growing the Carrier Business – Between 2005 and 2014, carrier revenue increased by 87% ▪ By the end of FY 2016, the carrier business under Mr. Barnhill’s leadership was deteriorating, so he hired a Vice President of National Carrier Sales & Business Development to focus on growing business with Tier 1 Public Network Operators in North America ▪ From FY 2017 to the early stages of FY 2019, while Executive Chairman, Mr. Barnhill oversaw the further expansion of the carrier business under CEO Murray Wright ▪ Restructured sales and business development efforts to strengthen customer relationships and offer more value - added products and services ▪ Focus on growing share of wallet with existing customers to drive more gross margin dollars ▪ Add new customers that will continue to generate additional growth in revenue and profits as the deployment of 5G technology accelerates ▪ Introduce TESSCO’s proprietary, higher - margin Ventev products into the carrier ecosystem ▪ Expand into higher margin, value - added software and services NEW APPROACH TESSCO CARRIER REVENUE ($M) Source: Company filings.

46 Mr. Barnhill Appears to Be Seeking Influence Over the Board DISRUPTS PROGRESS WITH COSTLY CAMPAIGN TO REPLACE DIRECTORS SOUGHT TO TAKE THE COMPANY PRIVATE AT DEPTHS OF PANDEMIC ▪ In March 2020, during the depths of the pandemic - related market sell - off, Mr. Barnhill sent a letter to the Board expressing an interest in taking the Company private. ▪ The Board immediately empaneled a Special Committee to engage in independent discussions and evaluation of Mr. Barnhill’s interest. ▪ The Special Committee was willing to enter into discussion with Mr. Barnhill and requested that he sign a conventional NDA. ▪ Barnhill refused to sign the NDA and seemed offended that the Special Committee would require a thorough and fair process. ▪ Weeks later, Mr. Barnhill announced he would withhold votes from the Board at the 2020 Annual Meeting. ▪ Just 81 days after the Company’s 2020 Annual Meeting, Mr. Barnhill launched his consent solicitation, aiming to remove a majority of independent directors. ▪ The Board attempted to reach a resolution with Mr. Barnhill, but Mr. Barnhill continues to insist on removal of a majority of directors and replacing them with a hand - picked group of directors that he refuses to allow the Board to even interview. ▪ Without interviewing Mr. Barnhill’s candidates, the Board could not agree to this request. Mr. Barnhill appears interested in buying TESSCO at a low price and is frustrated with the Board’s independence $4.00 $5.00 $6.00 $7.00 $8.00 $9.00 $10.00 $11.00 $12.00 $13.00 01/20 03/20 05/20 March 12, 2020 At COVID bottom, Barnhill announces intention to take TESSCO private From January 1, 2020 to March 11, 2020, the day before Mr. Barnhill disclosed his intention to take TESSCO private, the Company’s stock price had declined by 57% and was near its 52 - week low I intend to amend my 13(d) and reach out to “Partners” who will join with me to take TESSCO ‘Private’”¹ Source: FactSet. ¹Letter to TESSCO Board of Directors March 12, 2020; ²Extracted from Mr. Barnhill’s 13D filing with the SEC on March 20, 202 0

47 Mr. Barnhill’s Conduct Has Been Concerning Sharing of Material Nonpublic Information with His Nominee, John Diercksen ▪ In August 2019, there were Board communications regarding the status of the CEO search and potential compensation decisions for both the outgoing CEO and senior management ▪ Mr. Barnhill forwarded the communication to John Diercksen , now one of Mr. Barnhill’s nominees ▪ Mr. Diercksen responded to Mr. Barnhill’s email, copying a director and a third party unfamiliar to the other directors, thereby sharing material nonpublic information ▪ The Audit Committee took steps to ensure that neither Mr. Diercksen nor the third party with whom he shared the Company’s confidential information would further disclose the information or trade the Company’s securities ▪ In July 2020, Mr. Barnhill requested that an external IT company be allowed to deliver a presentation during a Board meeting to promote their products and services to the Company; the Board agreed ▪ Mr. Barnhill failed to inform the Board that a family member was listening to the Board’s private discussions with this external IT company via Zoom Undisclosed Involvement of Family Member in Board Discussions

48 Mr. Barnhill’s Conduct Has Been Concerning (Continued) ▪ In 2018 and 2019, Mr. Barnhill interacted with a former TESSCO employee on a number of occasions regarding Mr. Barnhill’s personal IT issues ▪ It became apparent to another director that the former employee was aware of sensitive Company and Board matters, which the former employee had learned during his interactions with Mr. Barnhill ▪ Following an Audit Committee investigation into the situation, Mr. Barnhill was reprimanded for his actions, and the Committee impressed upon Mr. Barnhill the paramount importance of all Board members maintaining confidentiality Leak of Material Nonpublic Information ▪ We believe that in early November 2020, Mr. Barnhill improperly forwarded a confidential Board communication to one of his consultants, again demonstrating a breach of protocol and poor attention to key public company formalities ▪ The Board will be considering this matter and determining an appropriate course of action Sharing of Board Discussions with Outside Consultant

49 John Diercksen’s Previous Interactions with TESSCO Demonstrate His Close Ties with Mr. Barnhill and Questionable Judgment ▪ In December 2018, Mr. Diercksen worked as an advisor to TESSCO at the behest of Mr. Barnhill, who advocated for Mr. Diercksen to be CEO. During the course of this engagement, Mr. Diercksen was taken into TESSCO’s confidence and received material nonpublic information. ▪ Mr. Barnhill forwarded Mr. Diercksen a confidential internal email sent by one director to the Board, updating directors on the search process and related internal compensation decisions. ▪ Mr. Diercksen then responded to Mr. Barnhill’s email, copying TESSCO’s Audit Committee Chairman, Mr. Barnhill, and another individual who was unfamiliar to the other directors. ▪ Mr. Diercksen’s response – in which he stated that “[t]he entire board must be removed” and referred to certain strategic compensation decisions as “criminal” – came across as bitter and unprofessional. ▪ More importantly, by including the other individual on his email response, Mr. Diercksen shared material nonpublic information with an outside party. ▪ As a result, the Audit Committee Chair felt it necessary to respond, and Company counsel was called upon to coordinate a demand that Mr. Diercksen and the other individual confirm that neither of them would further disseminate confidential information or trade in TESSCO stock. Source: Email communication from John Dierckson to Robert Barnhill. 1 Barnhill letter to TESSCO shareholders issued on November 4, 2020. Despite Mr. Barnhill’s claim, Mr. Diercksen should not be viewed as an independent Board candidate In his own words, Mr. Diercksen states, “At Mr. Barnhill's request, I previously worked as a consultant for TESSCO and tried to assist with the strategy decisions a few years back.”¹ Unknown third party

50 TESSCO’s Employees Viewed Barnhill as Resistant to Change “The CEO does not embrace change causing the company to not meet its potential.” – Finance Employee, January 22, 2016 “Outgoing CEO/COB wasn’t open to change, new ideas, or those that were different than his. Company tended to function as a dictatorship as a result.” – Anonymous Employee, January 19, 2017 Source: GlassDoor.com “The CEO holds this company in the past… Tessco’s priorities are CEO, Tessco, customers, employees. They have never missed a dividend payment because the CEO is the largest share holder yet they have missed paying the employees.” – Leadership Employee, January 11, 2016 “Strong resistance to organizational change.” – Purchasing and Inventory Management Employee, March 1, 2011 “CEO refuses to retire and dismisses new ideas.” – Sales Employee, August 14, 2015 “Upper Management / CEO is adverse to change…” – April 14, 2015 “CEO who wants to [be] revered as cult hero. Could care less about his employees, Its all about him.” – VP, July 13, 2011 “The management at TESSCO seems to generally ignore advice, so providing feedback is pointless. It’s no wonder their performance in the telecommunication industry is lackluster.” – Anonymous Employee, September 30, 2011

52 Barnhill’s Claims Are Misleading

53 Barnhill’s Misleading Claims BARNHILL’S MISLEADING CLAIM TESSCO’S RESPONSE “[T]he Board has remained complacent and has refused to make the necessary changes to return the Company to profitability.” ▪ The Board took the strongest possible action it could take – it replaced the CEO in the fall of 2019, less than a year before Barnhill started demanding that the majority of the Board be handed to him. ▪ The Board and management team have been focused on returning the Company to profitable growth and are dedicated to pursuing aggressive profit improvement actions. ▪ TESSCO’s strategy, as crafted by management under the oversight of the Board that Mr. Barnhill now largely seeks to replace, is the result of a thorough analysis of TESSCO’s business, our competitive positioning in the marketplace and the optimal utilization of the company’s assets. “[I] nstead of growing the Company’s highest margin vertical, Value Added Resellers and Integrators (“VAR Integrators”), and expanding revenues from self - maintained users like public utilities and railroads, the Company instead pursued revenue growth in its least profitable market, Public Carrier, investing dollars to barely make cents.” ▪ The focus on public carriers was a strategy adopted by Mr. Barnhill, who grew carrier revenue and dependence, and the company’s next CEO, Murray Wright. ▪ The current Board and management team are focused on VARs and executing the Board’s unanimously - approved three - pillar strategy. ▪ One of our primary goals is to grow our value - added distribution business. While COVID - 19 has had a large impact on this business, we are actively pursuing initiatives, such as improvements to our tessco.com website, which we believe will enable us to capitalize on the favorable growth trends in that end market.

54 Barnhill’s Misleading Claims (Continued) BARNHILL’S MISLEADING CLAIM TESSCO’S RESPONSE “Since 2019, the Company has spent $8 million on internal use software. Despite this significant outlay, the TESSCO.com website needs updating to be a more meaningful source of revenue and to better represent the Company. Moreover, much of the Company’s investment in SAP has yet to be fully implemented.” ▪ TESSCO’s investment to replace the Company’s disparate and ineffective technology with a standardized, companywide software system was necessary following years of neglect under Mr. Barnhill’s management and leadership. The project is on - schedule for completion in 2020. ▪ The current Board and management team have made meaningful investments to enhance the Tessco.com website , which have been deployed over the past few quarters. ▪ Tessco.com now includes industry vertical specific “landing pages” to address the “self - maintained” and “private system operator” customer areas of interest/purchase. “Over the past two years, the Company has taken inventory write downs totaling over $20 million. This clear example of working capital mismanagement is unacceptable and speaks to the immediate need for corrective actions.” ▪ Upon arriving at TESSCO in Q3 of fiscal 2020, our CEO Sandip Mukerjee , immediately embarked on a thorough review of our assets and investments. As a result of that study, we sold the Retail Business in October 2020 to focus exclusively on the higher - margin Commercial Business. ▪ We've tightened our inventory management, and our new CEO is very focused on the highest turning SKUs. We’ve significantly reduced inventory level, and we are renegotiating many customer contracts and lowering overall SG&A expenses.

55 Barnhill’s Misleading Claims (Continued) BARNHILL’S MISLEADING CLAIM TESSCO’S RESPONSE “[T]he Board further entrenched itself by doubling the threshold required for shareholders to call a special meeting.” ▪ Over 10 years ago, when faced with shareholder discontent about the best way to maximize value, Mr. Barnhill, as Chairman and CEO, strongly advocated for increasing the threshold for shareholders to call a special meeting from 25% to 50%. ▪ Given Mr. Barnhill’s expressed desire to buy the Company, the Board took action to ensure that a small group of shareholders could not wreck havoc with the proper process for an insider buyout by threatening a Special Meeting. ▪ In addition to having the right to call special meetings, TESSCO shareholders also have the right to take action via written consent, giving them ample opportunity to act outside of the regular annual meeting cycle .

56 Barnhill’s Misleading Claims (Continued) BARNHILL’S MISLEADING CLAIM TESSCO’S RESPONSE “…the Board has declined to make the retail sale transaction documents public .” ▪ TESSCO has made the retail sale transaction document public in a public filing on November 6, 2020. ▪ It is important to note that TESSCO was not required to file the agreement until its February 2021 Form 10 - Q filing, but in the interest of transparency filed it earlier; TESSCO took a few days to redact non - material but commercially sensitive terms. “…the company disclosed that it has entered into a new credit agreement (the “New Credit Agreement” ) that contains a change of control provision that would be triggered by the successful consummation of Mr. Barnhill’s consent solicitation (i.e., a proxy - put), unless the Independent Candidates are approved by the current Board (such approved Independent Candidate, a “Continuing Director”).” ▪ TESSCO has publicly confirmed that the following statement it made in its Definitive Consent Revocation Statement on October 15, 2020, with respect to its prior Credit Agreement entered into on October 19, 2017, also applies to its Credit Agreement entered into on October 29, 2020: “The Board has approved the Barnhill Nominees for the limited purpose of constituting “Continuing Directors” under the Credit Agreement . As a result of this action, the election of the Barnhill Nominees will not constitute a change of control under the Credit Agreement even if the Barnhill Nominees comprise a majority of the Board after the conclusion of the Barnhill Consent Solicitation . ” Source: Company filings

57 Conclusion

58 Conclusion We urge shareholders to support TESSCO’s transformation by signing the GREEN consent revocation card The Board has been substantially refreshed and is focused on creating shareholder value ▪ Five directors were added since 2018 and three legacy directors will retire before year - end 2020 ▪ The Board acted quickly and took steps to replace the prior CEO when his performance was disappointing ▪ Mr. Barnhill’s consent solicitation is seemingly aimed at regaining excessive influence over the Board of TESSCO ▪ Mr. Barnhill does not appear to have any new ideas and has previously expressed strong support for our current strategic plan ▪ The Board believes Mr. Barnhill’s consent solicitation reflects Mr. Barnhill’s frustration with the Board members he once respected because the Board members have refused to allow him excessive influence and insisted on a fair sale process ▪ Mr. Barnhill’s hand - picked nominees do not appear to have experience or skills that would add to our Board Mr. Barnhill’s campaign is disingenuous and an unnecessary distraction TESSCO is well positioned to capitalize on massive growth in wireless infrastructure spending ▪ The Company’s new management team has developed a strategy – explicitly supported by Mr. Barnhill – that should lead to profitable growth and extend the Company into higher - margin, value - added distribution, industrialized proprietary products and solutions ▪ The Company’s initiatives to modernize its neglected technology and operations are well underway ▪ TESSCO recently entered into an agreement that, if closed, will result in its exit from its Retail Business, allowing TESSCO to focus its resources and team on the higher - margin, higher - growth Commercial Business
